4 Claims. (Cl. 220--94) This invention relates generally to the packaging arts and especially to handle devices to be assembled to containers for use in carrying such containers and in manipulating the same during pouring therefrom.
In the past, both rigid handles and pivotal wire bails have been commonly attached to metal cans having a capacity of a half gallon or more. The rigid handles, while extremely useful from the consumers standpoint, have effectively prevented stacking of the containers. This factor has led to unpopularity with both shippers and retailers. On the other hand, pivotal wire bails may be swung so as to lie closely against the container and accordingly have increased the stackability of the containers; but the ears or flanges by which such a bail is attached to the container tend to interfere with stacking of the containers; and when these ears are mounted in the top of the container, the bottom of the container must be correspondingly recessed to achieve full stacking capabilities.
Therefore, an important object of the present invention is to provide a handle device which presents a flat profile when assembled to a container.
A more general object of the invention is to provide a new and improved handle device for assembly to a container whereby to facilitate carrying the container and pouring therefrom.
Another object of the invention is to provide a handle device which normally assumes a position parallel with and hugging the top of a container to which it is attached.
Yet another object of the invention is to provide a handle device which affords a safe, comfortable grip.
Still another object of the invention is to provide a handle device having a non-corrosive mounting to a container.
A further object of the invention is to provide a handle device incorporating a leakproof mounting to a container.
A still further object of the invention is to provide a handle device having a mounting for use in positively attaching the same to a container.
These and other objects and features of the invention will become more apparent from a consideration of the following descriptions.
A handle device in accord with the invention includes a generally U-shaped handle having a central portion and coplanar end portions. The handle device also includes mountings at each of the end portions of the handle for cooperation with attachment sites formed in the top of a container to which the handle device is to be assembled. Each of these mountings includes both a tubular, radially resilient bushing having a tapered central bore and a tapered plug wedgedly insertable in the bore for expanding the same into sealing engagement with the edges of a hole fashioned in the top of the container to define an attachment site.
In order that the principles of the invention may be readily understood, two embodiments thereof, but to which the application is not to be restricted, are shown in the accompanying drawing wherein:
FIG. 1 is a perspective view of an oblong metal con tainer having a handle device constructed in compliance with the invention assembled therewith, the handle device being illustrated in carrying condition;
FIG. 2 is an enlarged perspective view of the assembled container and handle device of FIG. 1, showing the handle device in its normal position parallel with and closely hugging the top of the container;
FIG. 3 is an enlarged elevational view taken substantially along the line 33 of FIG. 2, the carrying and can-manipulating position of the handle being illustrated in broken outline;
FIG. 4 is an enlarged view taken substantially along the line 4-4 of FIG. 3 to show the cooperation between the tubular bushing and the tapered plug of a mounting used in attaching the handle device to the container;
FIG. 5 is a view similar to the showing of FIG. 4 but illustrating the tubular bushing and the tapered plug in disassembled condition;
FIG. 6 is a view of the arrangement of FIG. 5 illustrating the tapered plug partially assembled to the tubular bushing;
FIG. 7 is a view similar to the showing of FIG. 6 but illustrating a modified embodiment of the mounting of the invention; and
FIG. 8 is a sectional view of the arrangement of FIG. 7 illustrating the assembled condition of the plug and bushing.
Referring now in detail to the drawings, specifically to FIGS. 1 and 2, a handle device indicated generally by the numeral 10 is seen to be assembled with an oblong metal can 12 of the type customarily used in packaging automotive anti-freeze. The can 12 includes a body 14 and a lid or cover 16, the cover 16 having a central filling port which is closed by a crimp-type cap 18. In addition, the cover 16 is secured to the body 14 by means of a conventional double seam 20; and in use, the cover 16 s punctured with a venthole in a corner region 22 and is cut open with a pouring aperture at a diagonally opposite corner region 24.
The handle device 10 includes a generally U-shaped handle 26 which comprises a grippable central portion 28 and legs or end portions 30. The handle device 10 additionally includes a mounting or attachment fitting 32 at the terminus of each of the end portions 39, the mountlugs 32 cooperating with attachment sites provided in the can cover 16 in affixing the handle device 10 to the can. With reference to FIG. 3, the can cover 16 is seen to be fashioned with spaced attachment sites defined by circular holes 34; and the mountings 32 include bushings 36 that are each provided with a peripheral groove or reduced diameter portion 38 intermediate its ends for receiving the edges of a hole 34. With reference to FIG. 4, the bushing 36 is seen to be a tubular member having a tapermg, upwardly converging bore 40.
Each of the mountings 32 also includes a tapered plug 42 which is intended to be wedgedly inserted in the bore 40 to expand the same into sealing engagement with the edges of the hole 34. In addition, the mounting 32 comprises plug retention means acting between the bushing 36 and the plug 42 to hold the plug in wedged engagement with the bushing; and in the embodiment of FIGS. 1-6, the plug retention means is a resilient ring formation 44 fashioned on the bushing 36 at the inside surface of the large end of the bore 40 therein.
The components of the handle 26 and the components of the attachment fittings 32 are advantageously fabricated from a tough, resilient, chemically inert material which may be worked to a smooth, relatively soft surface. When the various components are so fabricated, the bushing 36 and the plug 42 are resistant to the action of chemically active materials packaged in the can 12; and furthermore, no galvanic corrosion can develop between the parts of the can 12 and the parts of the handle device 10. Moreover, the central portion 28 of the handle 26 may thus afford a safe, comfortable grip.
When the handle device is fabricated from such a material, the handle 26 is desirably arranged with the end portions 30 thereof secured laterally to the mountings 32 as is shown in FIG. 2, thus disposing the handle 26 normally in a position parallel with the top of the container and in closely hugging relationship therewith. So disposed, the handle device presents a flat profile having a very shallow projection above the top surface of the cover 16 as is shown in FIG. 3, this projection being less than the vertical projection of the cap 18 and substantially no greater than the projection of the double seam 20. Thus, the handle device 10 facilitates stacking of a number of the cans 12. When it is desired to use the handle device 10 for carrying the can 12 or for pouring the contents therefrom, it is only necessary to grasp the central portion 28 of the handle 26 and lift the same into the position shown in FIG. 1. Advantageously, weakened sections 46 are provided in the end portions 30 of the handle 26 adjacent the mountings 32, the weakened sections 46 defining a hinge axis and facilitating rotation of the handle 26 from its normal position hugging the cover 16 to the upright position that is associated with carrying and pouring. It is to be realized that the toughness and resiliency of the material from which the handle 26 is fabricated serves to return the same to its depressed position closely parallel to the cover 16 when the handle is released. The handle may also be molded with a convex curvature throughout or only at the hinge axis in order to insure the handle 26 snugly fitting the cover 16 when it has been released.
The desired toughness, resiliency, inertness and surface properties are provided in the handle device 10 by fabricating the same from a polyolefinic resinous material such as polyethylene; and in addition to the features and functions described hereinabove, fabrication of the various components of the handle device from a tough, resilient material promotes a tightly wedged fit between the plug 42 and the bushing of a mounting 32.
Assembly of a handle device 10 to a can 12 having a cover 16 perforated with apertures 34 will become .more apparent from a consideration of FIGS. 5, 6 and 4 taken in that order. First, the bushing 36 is assembled to the cover 16, the bushing being forced through the hole 34 until the edges of the hole reside in the groove 38; and advantageously, the portion of the bushing 36 which is to be forced through the hole 34 is somewhat smaller than the upper portion of the bushing which resides above the surface of the cover 16 whereby to facilitate this assem bly. Next, the tapered plug 42 is forced into the tapered bore 40, the ring formation 44 expanding radially to pass the plug 42 as is shown in FIG. 6. When the plug 42 has passed completely through the ring formation 44, the ring formation returns to its normal condition and acts to resist axial movement of the plug in the general direction out of the bushing 36, as is shown in FIG. 4. Furthermore, this latter action of the ring formation 44 preserves the wedged engagement between the plug and the bushing so as to preserve concomitantly the sealing engagement between the bushing and the edges of the hole 34 in the can cover 16.
While a particular embodiment of the invention has been thus far shown and described, it should be understood, of course, that the invention is not strictly limited :hereto since many rnpdjfications may be made. Therethe annular flange 52.
4 fore, and in order to enhance the understanding of the invention, a modified embodiment of the invention is shown in FIGS. 7 and 8. This modified embodiment incorporates certain elements which are similar to those found in the embodiment of FIGS. l-6; and accordingly, like numerals have been used to designate like parts, the suffix letter a being employed to distinguish those elements associated with the embodiment of FIGS. 7 and 8.
In the embodiment of FIGS. 7 and 8, the modifications are concerned primarily with the mounting or attachment fitting 32a and more particularly with the manner of providing retention of the plug 42a in the bushing 36a. Before turning to a more detailed consideration of the plug and mounting arrangement of the embodiment of FIGS. 7 and 8, it should be noted that the bore 40a is substantially cylindrical rather than being tapered and is fashioned with a conical undercut 48 at the end which is adapted for entrance of the plug 42a.
The particular plug retention arrangement provided in the embodiment of FIGS. 7 and 8 includes a counterbore 50 which is fashioned in the bushing 36a at the upper end thereof, In addition, both the bushing and the plug are made of a thermoplastic material, the plug 42a being specifically provided with an annular heat-expansible flange 52 disposed at the upper end of the plug 42a. So fabricated and arranged, the upper end of the plug 42a may be heated to soften the flange 52 so that the same may be flowed radially outwardly to form a head 54 that spreads over the shoulder between the walls of counterbore 59 and the walls of bore 400 whereby to lock the plug 42a in the bushing 36a after having been wedgedly inserted therein. An annular fusion joint 56 is advantageously created between the head 54 and the bushing 36a simultaneously with the creation of the head 54 from This fusion joint 56 creates a liquid and vapor seal as well as enhancing the plug retention characteristics of the head 54.
The specific examples herein shown and described are to be considered as being primarily illustrative. Various changes beyond those described will, no doubt, occur to those skilled in the art; and such changes are to be understood as forming a part of this invention insofar as they fall Within the spirit and scope of the appended claims.
