Referring to Figs. 3 and 4, it will be observed that in the preferred embodiment of the invention, the bottle It! has a neck ll provided with a peripheral shoulder l2, suitably spaced from the free end of the neck; forming an abutment over which the tear-off strip, to be described, is to be clinched. Cast into the neck above the tearing shoulder I2 is a relatively deep and angular hellcal groove, or pair of grooves, forming threads l3;
Note that the groove threads 13 are formed in a portion M, the exposed outer area of which is cylindrical so that the cylindrical outer cap, to be described, can slide freely thereon. The threads l3 terminate at their upper portions at least, in an abrupt or'square end I5, which forms a positive stop for the lug to be described. The cylindrical portion M of the neck I i has a shoulder H5 at its upper end, and the free end of the neck extends upwardly from the shoulder It in a slightly reduced end ll, of such outer diameter as to slidably receive the inner cap of the closure to be described.
The free end or mouth of the bottle comprises an annular wall or rim 18 having a depressed integral outwardly directed concentric frusto-conical web 20, having the plane end 2!, preferably extended slightly beyond the upper level of the rim l8. The web 20 joins rim l8 inwardlyof the outer end so as to form an annular groove, gutter or recess 22. Communication of the inside of the bottlel0 with the space surrounding the outer area of the symmetrical conical web is formed preferably by the provision in the web of at least two openings 23, which may each comprise round or other shaped openings, as the arcuately disposed oval openings shown in Fig. 8. The open.-
ings are each eccentric to the longitudinal. axis.
bottle manufacturers, than to goto the troublev and expense of equipment and training necessary to provide the preferred form of unitary bottle according to the instant invention. Re-
Vferring first to Fig; 6, a bottleneck 24, provided with the tearing shoulder l2, and recessed or grooved thread l3, shoulder'lfi and reduced outer portion H as in the disclosures of Figs. 3, 4 and is provided, and there is also provided a reduced bead H and recess as an anchor for the independent adapter 26. The -adapter26maybe of any material such as molded glass, in which case it may be cemented to'the bottle, or even fused thereto if desired, or it? may, and. prefer ably does, comprise a stamping of sheetmetal V as shown. 7
The adapter 26 of Fig. 6 comprises a skirt 2], the outer diameter of which issubstantially identical with that of the reduced endll: of the bottle neck, and'has its lower edge crimped or bent over the bead 2 4 and'into recess 25, whereby-- the adapter is immovablyl secured substantially permanently to the bottle neck-2'4. Theskirt 21 of the adapter is bent over uponitself to define the annular rim 2%; and is stamped .to'form the webtll havingthe irusto-conical closed coaxial end 3|, and is provided With'the eccentric-taper tures 32 in as large number as desired; ,Obvi.-, .ously theadapter thus described can be stamped;
. moldecL'swaged, or otherwise formed. When the adapteris anchored to the bottle'jthe eliect is similar to that of the integral one piece bottle.
While the adapter of Fig. 6 is thoroughly practical and usable, it is relatively expensive to produce and'apply, and is thereforenot the pre- 7 ferred form, which, however, isshown infFig. 7.
In this form ,ofinvention thebo-ttle neck has the same reduced external portion l'l terminating in the shoulder 55, and the same cylindrical surw face I4-and tearing shoulder 12, as in the forms 7 described previously, although as will be later explained, the thread in the-cylindrical portion is modified. The mouth cfgthe glass bottle is formed by annular rim [9 having the internal shoulder: 29. The adapter comprises essentially' the closed Irusto-conical axial web 49, suitably apertured as at8'be1ow the closed end, 'andsultably disposed within the rim 1 9 upon the shoulder 29 thereof. Theadapter may comprise a mere spider, the radial legs of which'frictionally errgage the shoulder 29,1 although preferably the adapter includes an annular outer concentric rim having a resilient edge to frictionally en gage the inner surface of rim IS. The apertures 8 obviouslylmaybe as great in number as'dej sired and need not be disposed so that'a line parallel with the axislcan pass substantially con-r centrically through them, as'is desirable where Obviously the adapter of Fig.7 may be axially inserted to frictional seating afterthe bottle has been suitably filled. Of course it'isgcontemplated that theadapter of Fig. 7 may be permanently and positively engaged with the bottle in any desired manner if this should be found expedient, although'the'frictional engagement is satisfactory for most purposes. V
It is to be observed that is comprised on one side by the glass or other material rim l9, while on the other side and at the bottom, it is comprised of themetallicor composition adapter 49, and has apertures 8,
forming communication 7 between, the bottle interior and the'gutter.
' The closure element of this invention comprises preferably two elements, to wit, aninner cap 33 whic h forms the sealinglelement, andthe,
the bottle must be filled through such apertures.
I I the bottle of Fig. '7 provides a gutter as in the other form but which outer cap 34', comprising the seal ,actuater; V The inner cap 33, preferably drawn from a sheet of metal, comprises a larger cylindrical portion 35 arranged to tightly but slidably engage the re- V du'ced end I'I, of-the bottle end, and has atransverse web 36 merging into the cylindrical extent by a recessed or annularly concave portion 31 aligned substantially with the rim l8, or 28, of
the bottle, and having a smaller or reduced cylindrical portion 38, concentric with thecylindrical skirt 35, the inner diameter of which cylinder is slightly greater, preferably,than the diameter of the; plane end 2| of the conical web-20. The
inner cap 33 has preferably sealing elements as-v sociated with it, and comprised for instance of a sheet of relatively soft sealingniaterial-Msuch as composition cork'or the like, with, a facing layer of metal foil to protect the s'ealif this should be: desired and'for'general'purposes it is preferred. "The sealing elements have registering coaxial openings 42 and respectively, ar-
duced cylindrical shank 38 of theinner cap.
outer cap is provided with a'band 44, an integral portion preferably offcap '34, but detached there 1 from throughout the periphery of the cap except for one or more slender weakened attaching tongues 45, so arranged as to permit easy manual manipulation to sever the cap 33 from band 44, after the latter has been anchored to the bottleranged for substantial registration with the -re-i neck by clinching about the shoulder -l 2;las will 7 be readily understood. ,The cap 33 at'its outer end has a conical portion 46 having an axial opening 41, of diameter sufiicient to have s'lidable; engagement over the reducedcylindrical end 38 of the inner cap, and includes a transverse sub- 7 stantially plane .Web" portion 48 to engage the convex side of ring 31 of the-inner captoapply sealing pressure thereto; H l
The, inner cap, with its associatedsealing ele-f ment 'frictionallyor adhesively secured in place therein is assembled 11113119 outer 'capr34with the reduced cylindrical shank 38 extending through the axial-opening 41, then the end of the tubularshank is spun over asat 48in such way as to permit a slight axial as well as rotative.
relative motion of the inner and outer caps.
, The bottle having been properly filled, as by the insertion ofpfilling tubes through the appropriate openings 23 or 32, an assembled closure is pushed over :the erid ofthe bottleneck until 7 the sealing. elements 40 .a'nd 4| engage yieldingly but sealingly both the upper edge surface of the i rim l8, 19 or 28, as well as the tapered surface of the cone below the plane endl 2i thereof, so as to seal the guttergand, ofcourse, thejopenings 23 or 8, etc.
While a the caps are thus firmly held, or after abutments 59 are formed and the caps rotated on their threads to 'force them axially downward, the lower edge'of tearing strip 44 is spun or'otherwise bent' about the shoulder I2 of the neck. Whilethe cap or closure is firmly held downwardlyflon the neck, and either before, during, or after the spinning of the tear ihg strip 44 on the shoulder, a pair of plungers are brought to bear radially 'of the cylindrical closure element in proper relation to the'threads l3 so as to form at least one,.and preferably a pair of diametrically disposed, inwardly extendnormal and preferred case, but may be made ing locking lugs or abutments arranged to fit tightly within the square thread recess 13, and of such size and shape as to positively engage the end shoulder l5 thereof when the cap is ultimately rotated. The threads l3 and bottle are so disposed that the median molding line 5! or other indicator has predetermined angular relation to the ends of threads 53 so as to facilitate the positioning of the bottle so as to cause the indentation of the walls of the outer cap characterizing the lug or abutment 5G, to be exactly and positively disposed in threads l3, without breaking the bottle.
Referring to Fig. 9 there is disclosed the same arrangement of parts as to bottle neck and closure assembly as in the preferred forms shown in Figs. 3 and 4 for instance, and the parts are all the same and have the same reference characters, although it may be preferred to form a rather deeper gutter than usual when the gravity valve element about to be described, is to be used, in order to secure such clearances to insure free and untrammeled gravity actuation of the valve in each direction. Seated loosely and gravitationally in the annular gutter or recess 22 of the bottle, and between the surface of the gutter and the surface of the sealing elements M! and M is the valve disc 52 having the central aperture 53. The disc is concave in radial section, and the upwardly inclined portions are short enough, preferably, as to just cover the apertures 23, or 32, without extending up the side walls of the gutter a distance sufficient as to cause it to be in the way of or in contact with the sealing elements as this is undesirable. A deeper gutter facilitates this. Obviously, tilting the bottle after twisting the closure on its threads and raising the sealing device, permits the valve element to fall away from the mouths of the apertures in the gutter, while still axially anchored and confined by engagement of the central axial bore of the valve disc over the truncated cone of the central web. This action permits the free fiow of the fluid from the bottle. Obviously as soon as the bottle is moved to upright position again, the apertures are again closed by the valve element 52. Clearly, if desired, the valve element might have any desired sort of facing or backing to facilitate its functioning. It is not necessary that there be a ground seal between the Valve disc 52 and the bottle gutter, as the mere closing of the apertures is sufiicient to make the bottle and apertures so airbound that but slight amounts of liquid, if any at all, can be caused to enter when the permanently attached closure is in place.
It will be understood that in all forms of the invention, after the outer cap strip crimped or bent into attached relation and the wall indented as at 50, the inner cap having been slid simultaneously on its guide surface to sealing relation with the end of the neck, it is necessary to move the outer cap axially out of its clamping engagement with the inner cap before the latter can move or be moved to permit pouring. In the form shown in Figs; 3, 4, etc., the initial rotation of the outer cap causes it to turn on threads 53 through abutments 50 and to be moved axially away from the end of the bottle neck, or mouth, carrying the inner cap axially with it, to unseal the closure. During this movement it is preferred that the inner cap have axial movement only. This is secured by the tight fit of the inner cap about the reduced end of the bottle in the more definite by the provision of a vertical rib or bead or the like on the neck (not shown), with which the inner cap may engage longitudinally, to form a cooperating crease or slight bend, or merely a frictional engagement tending to preclude rotation, although this affords a clearance through which liquids may seep. It is found that in some cases the reduced end of the bottle neck is not exactly round, but may be slightly oval by a minute degree. In this case it will require that the inner cap be slightly distorted to permit its sliding engagement with such reduced end, and this in turn tends to prevent rotation. Obviously rotation of the inner cap, if desired for any purpose, may be arranged or permitted, although it may conduce to more rapid wear of the sealing elements.
It is preferred, in any case, that the inner can have a fit sufiiciently tight about the reduced end of the bottle neck, as to minimize or preclude leakage of any of the liquid from the bottle, between the neck and the inner cap after pouring. This provision of the instant invention of a tight sleeve engaging the outer periphery of the bottle mouth as a seal, and the consequent elimination of back lash marks a feature of improvement of the instant'invention over that shown in my earlier annlication'Ser. No. 720.961.
It being recognized that the axial movement of the inner cap between sealed and unsealed relationship to the end of the bottle is the desired movement after disruption of the tearing strip and the outer cap, it will be recognized that any desired sort of thread arrangements may be used as may fit any required condition. Thus the external threads of the aforesaid application may be used with the instant closure, instead of the indented threads herein. Illustratively, it is recognized that it may be considered a little onerous to be required to twist the outer cap to the degree indicated by the pitch of the threads l3 of Fig. 3, to secure complete opening of the closure. The modification shown in Fig. 7 may be resorted to to secure release from looking pressure, or to secure locking pressure, with a minimum of rotational effort, but with possibly considerable manual sliding effort to effect the desired end. Thus a recessed thread groove 5% has a vertical portion 55, and a smallinclined wedging or locking groove 56. The indentation or abutment 50 of the outer cap, being disposed in the groove 54, may engage the inclined portion 55 to apply sealing pressure or the unseating of the inner cap, according to the direction of relative travel or rotation. After the initial unsealing pressure resulting from relative movement of the abutment and inclined thread, the abutment reaches the vertical groove 55, and the outer and inner cap may then be moved together amally to complete unsealing and the establishment of pouring relation by manual pull. Conversely, to seal, the outer cap carrying the associated inner cap, is pushed axially toward sealing and thereafter, the abutment engages the inclined groove portion to force the closure toward sealing.
Attention should be directed to the preferred form of closure element in that the reduced cylindrical extension 38 of the inner cap, is spun or turned over at 48 to form the pouring mouth of the closure bottle end itself, to prevent the 'insertion of any refilling tubes in either of the respective apertures, or for such like purpose. From the viewpoint of pouring, the reduced cylindrical spout thus provided enables the liquid V to emerge from that aperture 8-, 23 or 32 having the lowest point from which it flows smoothly in of the bottle adjacent tosaidrim and having a a small stream through the spout 38. Simultaneously air entering'the upper portionof the mouth of spout 38 passes down around the frustoconical central element into the upper portion of the highest aperture 8, 23 or 32 to vent the bottle and permit free and but slightly restricted flow. When inltilting the bottle rafter pouring 10 thereare no straggling drops left on the edge of mouth '38, as the stoppage of pouring is practically instantaneous." Moreover, as eXplained the that'is between the upper-surface of the gutter and the spout at the time the valve element closes the apertures through the gutter into the bottle Will' remain in place, or, depending upon the degree of sealing, will, slowly seep back'into' the bott1e a V ,7 c
