No. 129,006, filed Mar. 29, 1971, entitled Shoe Cleaning-Polishing Device and Method of Making Same," now US. Pat. No. 3,722,021; which application was in turn a continuation-in-part of application Ser. No. 39,275 filed May 21, 1970, now abandoned.
BACKGROUND OF THE INVENTION One of the most disagreeable household tasks yet unaided by the advance of science, is the shining of shoes, a fact believed to result from the lack of creativity and invention contributed to date in the field.
The present inventions relate generally to the use and refinement of manually operated shoe polishing devices employing an aerosol can containing shoe polish. Though obvious in concept, utilization of the aerosol can as such in this context does not, to applicants knowledge, reflect in any prior invention, although Petion, US. Pat. No. 2,972,768, issued on Feb. 28, 1961, does refer to a pressurized container which in the drawings resembles a small cylinder tank with a novel escape valve. However, in Petion the need to use both hands to (a) depress a knob (No. 54 on Sheet 1) on the cover and (b) to simultaneously turn the elongate base plate from one position to another, made it impossible for a person to perform all of the traditional operations in the polishing of a shoe without causing the hand holding the shoe to repeatedly divert its grasp to engage in extrinsic tool manipulations. The inventions claimed in our co-pending Application, as further improved by novel and useful additions and changes now to be described, permit the hand holding the shoe at all times to retain its grip firmly on the shoe while the hand holding the device never loses contact with it during the entire sequence of traditional cleaning and polishing operations.
In a context in which millions of persons can be immediately assisted at low cost to conserve time and strength, any useful improvement admittedly novel should warrant serious patentable consideration. Each of the novel features now to be discussed contributes to make more accessible (because of their economical cost), more convenient and more useful, shoe shining devices containing an aerosol with polish. It is believed that taken as a class these devices stand as the first significant technological advance in the art for centuries.
SUMMARY OF THE INVENTION:
It is a general object of this invention to provide novel integrated shoe cleaning-polishing devices which may be held in one hand through the traditional sequence of cleaning and polishing procedures while the other hand at all times retains its original fast grip on the shoe, completing all of said tasks in a simplified and economical manner, and some embodiments of which devices accomplish all of the foregoing steps without allowing the motor hand to be dirtied by direct contact with the dauber, brush or buffer.
A purpose of the inventions claimed is the disclosure of new means of securing a fabric (lambswool, cloth, etc.) shoe polishing buffer onto a housing contoured to the circumference of an aerosol can containing shoe polish, contributing to create thereby an integrated device for the polishing of shoes.
It is a further specific object of this invention to suggest means of attaching a shoe polishing brush to said device, by which the device may be more expeditiously constructed and an improved aesthetic appearance achieved.
Yet another object teaches means of receiving and retaining aerosol cans in durable housings formed and contoured to the approximate circumference of said cans, allowing their insertion and removal without undue pressure or other strain on said housings.
Yet another object of the inventions here described is the use of identification windows within a sleevehousing utilized as a shoe cleaning-polishing device, providing a means of contents-identification as well as economy in manufacture.

DETAILED DESCRIPTION Referring now to the drawings more in detail wherein like numerals designate like elements throughout the various figures, FIGS. 1 through 6 show a preferred embodiment of the present invention reflecting improvements contained in this Continuing Application. It will be noted that this device is in effect a sleeve housing I I in which a replaceable aerosol can 15 is lodged. The lower end of the sleeve-housing is closed, and protruding from said end a dauber 17 is positioned under a removeable protective cap 19 to be conveniently used also as a base. As FIGS. 1 through 6 incorporate most of the novel features claimed herein as invention, they will now, following this initial general disclosure, be examined in greater detail as the subsequent drawings and explanation make this preferred embodiment the more easily understood.
In FIG. 1 we look down at the same device pictured frontally in FIG. 3 as it stands in an upright position on its lower dauber-protective cap 19. In FIGS. 1 through 4, an aerosol can I5, containing an expressible shoe polish, is shown in planned conjunction with the housing: The broken-away portion of FIG. 2 illustrates the manner of firmly lodging the can within the housing, namely by employing bosses 20 in wedging relationship with its lower chime 38.
One notes in FIG. 3 the cut away portion of the compensator ring (coordinate plastic ring-collar) 14. Once this compensator ring 14 is placed upon the aerosol cans upper chime 38, the can is in condition to be inserted into the sleeve housing I 1. It is in this closed position that the can, the ring and the housing appear in assembled relationship in FIGS. 1, 2 and 4.
Affixed to this sleeve housing 11 are a buffer 12 and a longitudinal brush 13 as well as dauber brush 17. In some embodiments it will not be necessary to utilize the dauber brush 17, which would in turn obviate the necessity for dauber protective cap 19: Under such circumstances, the added diameter footings l8 permit the unit to stand upright freely without additional support. The inventions contained in FIG. 5 are explained in greater detail in the multiple blown-up Figures appearing hereinafter.
Buffer Attachment Means The attachment of a buffing surface to a buffer handle has been traditionally achieved thusly: A lambswool or other fleecy material is positioned over a cushioned under-bed, then fixedly attached at both ends of a rectangular, flat backing. In the case of a plastic sleeve-housing into which neither nails, staples nor screws can be reliably fastened, different means must be supplied by which to fasten the buffing material to the housing, it being operatively insufficient that said ends be simply glued or sewn onto the top and ends of the under-bed. Several such novel means are now described, without attempting thereby to limit the scope of the invention as hereinafter claimed.
FIG. 7 shows the buffer 12 on its traditional underbed 21: FIG. 8 shows a cushioning material split equally into two parts 21 longitudinally, placed over a plastic under-bed in the nature of a platform which is similarly split longitudinally and raised above the level of the upper wall of housing 11. This leaves a passageway or channel 25 between the raised plastic underbed and the housing shell, as well as a slight separation between the divided underbed halves. This divided resilient support remains capable of cushioning the bufi'mg fabric 12 despite the presence of the center air strip running its entire length.
A strip of buffing material 12 (FIG. 9), somewhat longer than the whole length of the buffer bed, is made into an endless belt (FIG. 10) by sewing to each of its two ends, one end of a piece of elasticized material 12A. Taking the buffer shown in FIG. 10 in two hands, with the thumb and forefinger of each layer the sewn joint, it can be seen that the elastic 12A may be pulled apart a sufficient distance to allow it to pass between the divided plastic under-bed platform of the sleevehousing, over each side of which the sponge rubber strips 21 have been placed. As thus extended the elastic is moved longitudinally in a sliding motion through the free air space between the sides of resilient supporting material 21, twisting down into passageway 25 where it is allowed to contact thereby pulling closer together the ends of buffer 12 and creating a snug total relationship with the sponge rubber 21 and plastic under-beds.
This solution provides a convenient and aesthetically refined bufi'er-attachment by a means requiring a smaller amount of resilient supporting material 21 (due to the dividing air space), and whereby the buffer ends finally are securely affixed in the interior of the housing at a spot not otherwise accessible. The buffer 12 may be removed by again stretching the elastic 12A, allowing it to be easily slid out between the supporting sponge rubber 21 and plastic under-bed sides. This solution would as a practical matter not be possible if only the lambs wool or other fabric were utilized in an endless belt, due to the difficulty to be encountered in gluing the supporting resilient material onto the plastic bed and at the same time achieving a snug fit of the buffer fabric over the resilient supporting material 21: The passageway 25 dimensions would not only have to be measurably increased to accommodate lambs wool which varies between five-sixteenths to three-fourths inches in thickness, but a long aperture of a depth suitable for such heavy material would be aesthetically unattractive, yet necessary to prevent the crowding of the material.
It will be also noted that upon use many buffing fabrics elongate: Where the ends are fixedly attached at the ends of the buffer bed the growing slack in the material becomes offensive, yet there is no provision for its disposition. The use of elastic 12A in the buffer 12 under-structure (see FIG. 10) automatically contracts the exposed buffer surface to obviate this surplus goods" problem produced by elongation through use.
Other means of attaching buffing material 12 to a plastic base of housing 11, where a supporting resilient material 21 must cushion the buffer, is shown in FIGS. 12 through 160. Here resort is taken to a plastic wedge 26 having teeth 27 which engage with similar teeth 27A on the interior sides of the passageway 25A. By first placing the ends of the buffer in passageway 25A, then compressing wedge 26 and causing it to pass into the passageway 25A, the wedge 26, having increasing width and increasing thickness (see FIG. securely fastens the fabric at the end of the channel. Once the teeth 27 of the wedge engage with the teeth 27A of the interior of the passageway, the buffer is held securely by pressure of the wedge. Note that this solution does not contemplate a divided bed of resilient material 21, but rather a solid bed 21A over a passageway 25A which no longer needs to be split to allow longitudinal sliding entry of the elastic.
Another species of wedge 26A is shown in FIG. 16 and 16a in which the teeth 27 of the wedge engage against similar teeth 27A in the lower bed of channel 25A (in FIG. 16), compressing hard sponge-like material 28 between the jaws of the wedge, with the reversed upper teeth 27B of the wedge preventing the withdrawal or slippage of the buffer fabric once the wedge 26A is properly positioned. In both this and the preceding embodiments the wedge may be withdrawn and repositioned at any time to take up slack in the buffer 12 created through use.
A further means of attaching buffing material to a plastic housing for use as a shoe polishing device is shown in FIGS. 19 and 20. Lambs-wool 30 or similar fleecy fabric is cut to a width slightly greater than that of the under-bed 21A, and a length greater than that of its bed 11A, with the excess goods at both ends being turned under and sewn transversely at 32A into an open loop 32 (FIG. 19). Such a loop, when slid over the end pins 31 shown in FIG. 20, provides a solid means of affixing the buffer to the device, and permits easy replacement of the buffer when it has become worn.
Each of the aforesaid means of attaching the buffer to the device performs useful purposes not otherwise nor previously achieved by any buffer or similar device known to Applicants.
Brush Attachment Means The attachment of a polishing brush to a sleevehousing of this character, purposing to achieve thereby a shoe polishing device at least partially integrated, presents a fastening or adherence problem aggravated by the active use to which the brush will be put.
Reference is made to a commercial product sold under the trademark BRUSHLON (FIG. 17), consisting of an underlayment of urethane 29 into which are adhered thousands of bristles 13 in intensive placement thereon. The BRUSHLON underlayment 29 is of uneven height; viewed from the side (FIG. 17) its base presents an undesirably irregular appearance when used as a basic part of a consumer product such as a shoe shining device for personal use. However, the use of BRUSHLON in the present integration is otherwise advantageous because it may be easily cut to any size, and may be readily glued.
FIG. 18 shows a cut-away upper portion of a sleevehousing 11 running the approximate length of a coordinate aerosol can. The gallery 118 surrounding its upper perimeter is believed to be both novel and useful in the following respects: First, it places a wall in front of and slightly above the brushs underlayment 29 around its entire edge, thereby concealing its irregularity as well as the rough jointure of the otherwise flat backing of the device 11 with the flat base 29 of the brush. Second, in the production process where manual or even machine placement of a brush element on an otherwise flat surface is necessary, misplacement may easily occur: Where there is a known recess of fixed dimension and shape into which an object of similar size and contour can be quickly placed, the problem of misplacement is avoided inasmuch as the brush can only be lodged accurately within the recess if it is to be placed there at all. Third, the capability of the brush, when used, to withstand lateral and longitudinal pressures and movements is greatly increased where its sides are encased within and lodged against firm walls: The gallery 118 provides a solidity without which the effectiveness of the BRUSHLON material for such purposes is significantly diminished. Fourth, a device of this character receives hard handling; while in use it is in almost constant contact with shoes. Were the gallery not utilized, the corners especially of the brush material would receive incessant bumping and knocking; by utilizing the gallery or shield" around its corners the brush will not be repeatedly thus pried loose from adherence to the base.
Aerosol Can lnsertion and Retention Means lt has been found that the sleeve-housing device pictured in FIGS. 21 and 23 may be most economically cast first in two lateral halves as the cost of an injection mold (for quantity production of plastic pieces) is greatly increased by its depth; the halves are then joined by gluing. When a can is inserted into the housing, the upper end of this device (it being there just large enough to admit the can) is subjected to a strong horizontal outward pressure at the moment of the passage of the chimes 38 (the enlarged diameters of metal at top and bottom of can). Unless precautions are taken such lateral force being often reapplied must in time separate the upper portion of the longitudinal halves of the housing at their common joint.
Applicants have devised a novel means of harmlessly diverting this separating force caused by the cans insertion and removal, without impeding the convenience of its use. Reference is made to the six (which number may be greater or less than six) flexible extensions 33 appearing in FIGS. 21 and 23, which extensions are integrally a part of housing 11. A circle may be drawn touching the innenrlost tips of the aforesaid extensions 33: This circle, being of lesser diameter than the circle formed by the chime 38 of the inserted can 15, must be increased in size in order to permit the cans insertion. At the moment of insertion the angle of force upon the extensions 33 lies in a horizontal plane: However, this force does not act directly on the joint which adheres both halves of the whole housing, but rather simply pushes back the six raised, flexible extensions 33, resulting in a fulchrurn or hinge effect at their bases. After the chime passes, the extensions return to their original positions and serve to hold the can firmly within the housing.
The profile construction of the extensions 33, as shown in FIGS. 24, 25 and 26, discloses that their thickness increases generally as they ascend, then attenuates at their tip. Upon upward removal of the can the lateral pressures commence just above the level of the housing top; these grow more severe as the can rises, reaching their most destructive force at the upper level of the extensions 33 where the sideward force is imparted least of all to the main devices common longitudinal joint, being spent instead in the flexing of the extensions.
FIG. 27 discloses a type of protrusion or extension different from the others pictured in that the nib" or plastic extension points downward rather than up. This configuration operates especially well if the sleeve housing has an open lower end on which similar protrusions have likewise been placed so that the can is re tained by such protrusions at both ends serving to retain it snugly from within.
As an alternate construction, the extensions 33 may be affixed to an annular upstanding neck such as neck 24 pictured in FIG. 34 (but without machicolations), or as integral parts of a separate ring affixed to the said neck.
Compensator Ring (Coordinate Ring-Collar) to Accommodate Varying Can Diameters The importance of the aforesaid destructive force is greatly aggravated by one condition which prevails generally in the United States today within the can industry. For reasons peculiar to their own stell procurement and manufacturing processes, the large tin can companies such as American Can Company and Continental Can Company refuse to warrant the outer dimensions of the chimes of cans of the general sizes here under discussion. Not only will these can companies not assure purchasers of a responsible tolerance in said diameters, as, for example, plus or minus one thirtysecond inch; but the can companies will in fact 'not warrant or even express these outside dimensions within any tolerance whatever.
it is obviously difficult to design plastic sleevehousings to snugly accommodate cans of great potentially varying diameter; if such housings are merely designed for cans of the usua external dimensions, a minority of cans might be of a width, say, one-eighth inch greater than the average and these few could critically damage the sleeve-housings upon their forced insertion and removal. One novel and useful method of achieving secure retention of the can yet with a flexibility sufficient to allow cans of varying external chime dimension to be reliably inserted into a sleeve-housing having a neck of constant circumference, involves the utilization of a compensator ring as now described. See FIGS. 28-34.
A ring 14 made of a flexible plastic-like material is affixed to the top chime 38 of the can of polish by means of multiple hooks 35 which descend at planned intervals from the rings inner circumference. These hooks are of a length and shape such as to flexibly accommodate the forced insertion of cans of varying diameters, said hooks 35 gripping the can 15 from underneath the upper chime 38 when the ring is forced solidly down over the top of the can. See FIG. 32. The can is prevented from moving upward relative to the ring 14 by arcuate lips integrally a part of said ring.
Whereas the housing neck 24 is greater in diameter than the inner circumference of the compensator ring 14 and then the circle (of flexible diameter) of hooks descending therefrom, it is less than the diameter of the n'ngs outer circumference from which a side wall descends. (FIG. 32) When assembled, an annular protrusion 36 on the inside of the outer wall of the ring forms an interference fit with a similar raised circumference 37 on the outside of the neck of the housing; both pieces preserve a constant diameter and their respective raised circumference 36 and 37 co-act compatibly to insure the can 15 being held securely within the device.
As alternatively shown in FIGS. 33 and 34, the neck 24 of the housing 11 may be of a slightly lesser diameter, but slotted with machicolations 39 of a size, shape, placement and number determined by the size and positions of the hooks 35 descending from the inside circumference of the snap ring compensator. When the ring is positioned on the can and the can inserted into the housing (FIG. 33), the backs of the hooks protrude laterally from the cans upper circumference into their respective slots cut out of the neck specifically to accommodate such protrusions. Where an unusually large chime diameter 38 forces the hooks far backward, the machicolations in the neck easily accommodate the excess by permitting the backs of the hooks to further enter the cut-out voids 39.
Under both alternatives described above, whereas the tips of the hooks 35 (normally but not necessarily spaced equidistant about the inner circumference of the ring) can create circles of different diameters depending upon the diameter of the inserted can, by means of the novel comparator ring described the can is lodged solidly within the ring (by its circle of hooks) and the ring itself is thereafter lodged firmly over and on the housing by means of its outer rim of constant diameter interacting with the constant diameter neck 24 of housing I] being both unaffected by variances in chime 38 diameter.
Identification Window for Aerosol Housing Reference is made to FIG. 35 in which an aerosol can (15, in dotted line) has been packed within a sleevehousing 1 l which provides circumferential backings upon which the polishing tools (brush l3 and buffer 11) are conveniently placed. The use of such a housing normally creates a problem of contents-identification in that, if made solidly, the walls of the housing preclude the user or viewer from reading or otherwise learning the contents of the enclosed can as described on the cans label. This defect is better understood in the knowledge that the sleeve-housing is designed to accommodate easiest insertion and withdrawal of random aerosols, thereby encouraging it to serve as a vehi cle to dispense and to apply polishes of different colors, e.g. black, brown. Thus one utilizing the device occasionally with different aerosol inserts would not be able to know from looking at the outside of the device, what the color then contained in it might be. To alleviate this problem and achieve other useful purposes now described, an identification window is disclosed in FIG. 35 by which the viewer or user may at once determine the nature of the contents simply by looking through" the window of the device at the contained cans trade dress.
The cost of devices of this character, manufactured for consumption on a mass basis, is in large measure determined by the weight of plastic used therein. By creating a window in one (or more) side of the device, a significant amount of plastic is saved without sacrificing strength or function. A further economy is achieved in that by utilizing the trade dress already on the can anyway, it is unnecessary to place lettering or an identifying label on that side of the shoe device. Labels of a type appropriate for this usage cost in quantity from one to three cents each, possibly more depending upon the material used: But even the most durable commercial labels, e.g. printed foil, do not withstand the expected heavy manual use of this type of device, as after even mild use these become tattered. Cost-savings directly flowing from the omission of such a label on the device and from the reduction in weight of the plastic material required, are such as justify the use of such an identification window on an economic basis alone, quite apart from the functional contribution of the window.
The window pictured in FIG. 35 does not exhaust the scope or nature of the invention described. The window may thus be long and narrow, or there may be two or more windows critically placed on the housing device to disclose information or serve other express purpose. See FIGS. 36 and 37. The identification window concept can be also embodied on a second or even three or four sides of any housing in which an aerosol can is contained for storage or utilitarian purposes. It is clear that the scope of the invention in relation to housings for aerosol cans goes farther than reference solely to shoe cleaning and polishing devices.
A full explanation of the identification window must include reference to the trade dress used upon the can placed within the device. It will be noticed that the dimensions of the window in FIG. 35 are of a specific, known size: In the unrolled, flat representation (FIG. 38) of the trade dress (which in production would be either printed directly on or in the form of a label wrapped around the aerosol can as in FIG. 39), these same dimensions are directly adopted for correlation with the window aperture. The trade dress pictured in FIG. 38 is divided laterally into segments of equal size; the size of the segments is determined by the size and text requirements of the label interacting with the window shape and configuration of the housing. It is stressed that the correlated trade dress or label and identification window are co-equal features of the invention and coordinate parts thereof.
Aerosol Shoe Shine Device With Dirt-Free Handle It will be noticed in FIGS. 2, 3 and 4 of this Continuing Application, for one to clean and polish shoes utilizing the devices there pictured presents the possibility of dirtying the motor hand (i.e. the hand holding the device) by its contact with longitudinal brush or buffer. It has been found through extensive experiment that with aerosol devices employing buffer, brush and dauber virtually no dirt does in fact reach the hand when holding the device from either the brush side or the buffer side. However, some persons will no doubt dispute this, and large numbers of persons will conclude, however erroneously, in considering the use of these devices, that their hand would become dirty by touching the brush or the buffer.
A perhaps unreal, but nevertheless practical problem therefore tends to thwart public acceptance of this device, in that there is a natural disinclination on the part of many persons to permit their hands to fall in contact with a surface which, rightly or wrongly, they consider to be dirty. The inventions pictured in FIGS. 40 and 41 solve this problem. A person grasping handle 43 has at his immediate control without changing the hands position on the device, both brush and buffer: In neither case does the hand come in contact with an offensive surface.
A further embodiment of the aerosol side handle" concept is pictured in FIG. 41, in which to obtain a slightly more comfortable working position than is available in the configuration shown in FIG. 40, two handles have been constructed, each directly opposite a working surface. Hand contact with any working surface is again totally avoided. Although this device becomes somewhat more cumbersome in its employment,
it nonetheless presents the same dramatic capability of the other devices pictured in this entire Application, in which it is possible for one hand alone, without for an instant losing physical contact with the device, to perform all of the multiple steps in the polishing of a shoe while the other hand at no time relinquishes its grip upon the object shoe.
FIGS. 44, 45 and 46 show alternative handle designs that may be employed with the embodiments of FIGS. 40 and 41.
The scope of the inventions described is set forth in the claims hereinafter following, and is not confined merely to the precise alternatives described above.
Invention claimed is:
I. An elongate housing device designed to receive an aerosol can or the like, said housing device having at least one open end defined by an axially extending neck portion. permitting an aerosol can to be disposed therein, and means for retaining an aerosol can body in said housing, said means including a ring member capable of being mounted on an upper region of a can body and including means for attachment to said neck portion, which comprises axially extending wall means formed on said ring and having an effective inner diameter greater than the outer diameter of said neck por' tion, protrusion means on the inner surface of said wall means and corresponding protrusion means on the axial outer surface of said neck portion over which said protrusio means on said outer wall means are engaged in a snap-fit relation thereby retaining said ring on said neck portion.
2. An elongate housing device designed to receive an aerosol can or the like, said housing having at least one open end defined by an axially extending neck portion, which open end permits an aerosol can to be disposed within said housing device, and means for retaining an aerosol can body in said housing, said means including a ring member capable of being mounted to an upper region of a can body and including means for attachment to said neck portion, said ring member being engageable with a chime formed on an upper portion of an aerosol can and includes mounting means adapting said ring for the accommodation of an aerosol can having a chime diameter of potentially varying tolerance, said mounting means including a plurality of flexible hook members extending axially downward of said ring member, each said hook member being joined to the ring member at a location disposed radially outward of the inner periphery of said ring member and said inner periphery having a diameter less than that of the can chime, such that upon assembly, the hook members may flex radially outward to permit a can chime to pass into engagement with said ring, with said hook members returning to a position where they are engaged beneath said chime.
3. A device as defined in claim 2 further including a plurality of slots formed in said neck portion. said slots being sized and positioned to receive said hook members when the diameter of a can chime is such that it would dispose the hook members outwardly of the inner peripheral wall of said neck portion.
4. in combination, an aerosol can containing an expressible product, and a housing device within which said can is mounted, said housing device having at least one open end which includes an axially extending neck portion, said open end permitting an aerosol can to be disposed therein, and means for retaining said can within said housing, which means includes a ring member mounted upon an upper region of said can and including means for attachment of said ring member to said neck portion wherein said means for attachment of the ring to the neck portion comprises axially extending wall means formed on said ring and having an effective inner diameter greater than the outer diameter of said neck portion, protrusion means on the inner surface of said wall means and corresponding protrusion means on the axial outer surface of said neck portion over which said protrusion means on the outer wall means are engaged in a snap-fit relation thereby retaining said ring on said neck portion.
5. In combination, an aerosol can containing an expressible product and a housing device within which said can is mounted, said housing device having at least one open end which includes an axially extending neck portion, said open end permitting an aerosol can to be disposed within said housing device, and means for retaining said can within said housing, which means includes a ring member mounted to an upper region of the can body and having thereon means for attachment to said nut portion, said ring member being engageable with a chime formed on the upper portion of an aerosol can and includes mounting means adapting said ring for the accommodation of cans having chime diameters of varying tolerances, said mounting means including a plurality of flexible hook members extending axially downward of said ring member, each said hook member being joined to the ring member at a location disposed radially outward of the inner periphery of said ring member and said inner periphery having a diameter less than that of the can chime, such that upon assembly the hook members flexing radially outward to permit the can chime to pass into engagement with said ring, with said hook members engaged at rest beneath said chime.
6. The combination as defined in claim 5 further including a plurality of slots formed in said neck portion, said slots sized and positioned to receive said hook members when the diameter of the can chime is sufficiently large that the hook members are thereby disposed outwardly of the inner peripheral wall of said neck portion.
