No. 461,902 Claims. (Cl. Hit-54) ABSTRACT OF THE DISCLOSURE A container having a sealed cover curved around a portion of the body portion of the container, the cover having two tear strips for progressively unsealing the cover from the body portion.
This invention relates to containers and, more particularly, to containers having removable cover members, which are particularly well adapted for use in commercial packaging materials for sale and shipment.
It is a primary object of the present invention to afford a novel container.
Another object of the present invention is to afford a novel container embodying a novel removable cover member.
A further object of the present invention is to afford a novel container embodying a novel cover member of the tearstrip type, which may be removed in a novel and expeditious manner.
Containers embodying cover members of the tear-strip type have been heretofore known in the art. However, containers of that type, heretofore, have commonly had several inherent disadvantages such as, for example, being diflicult to open; requiring that the cover member be made of undesirably thin or weak material; not embodying a cover member which afforded a practical closure member for reinstallation on the container after it had once been removed; not affording a sealed, or liquid type container; or being diflicult or expensive to manufacture, and the like. It is an important object of the present invention to overcome such disadvantages.
Another object of the present invention is to aiford a novel cover member for use on containers such as cans, jars, and the like.
Yet another object is to enable a tear-strip cover member to be constructed in a novel and expeditious manner whereby it may be constructed of relatively heavy gauge material and yet be manually opened with relatively little eflort.
A further object is to afford a novel container of the aforementioned type, embodying pull tabs constituted and arranged on the cover member thereof in a novel and expeditious manner.
Another object of the present invention is to aiford a novel container of the aforementioned type which is practical and eflicient in construction and operation, and which may be readily and economically produced commercially.
Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawings which, by way of illustration, show preferred embodiments of the present invention and the principles thereof and what we now consider to be the best mode in which we have contemplated applying these principles. Other embodiments of the invention embodying the same or equivalent principles may be used, and structural changes may be made as desired, by those skilled in the art without de- 3,347,467 Patented Oct. 17, 1967 parting from the present invention and the purview of the appended claims.
In the drawings:
FIG. 1 is a side elevational view of a container embodying the principles of the present invention;
FIG. 2 is an enlarged, detail sectional view taken substantially along the line 22 in FIG. 1;
FIG. 3 is an enlarged fragmentary elevational view of a portion of the container shown in FIG. 1, with a part of the cover member removed;
FIG. 4 is a sectional view similar to FIG. 3, but with an additional part of the cover member removed;
FIG. 5 is an enlarged detail sectional view taken substantially along the line 5-5 in FIG. 4; and
FIG. 6 is a fragmentary elevational view of a modified form of container.
A container 1, embodying the principles of the present invention, is shown in FIGS. l-5 of the drawings to illustrate the presently preferred embodiment of the present invention.
The container 1 comprises a can embodying, in general, a body portion 2, having a bottom wall 3 closing the bottom thereof, and a cover member 4 mounted on the upper end of the body member 2 in closing relation thereto. The body portion 2 and the cover member 4 may be made of any suitable material such as, for example, aluminum or tin plate, and the like.
The body portion 2 embodies a tubular side wall portion 5, and is open at the top. The bottom wall 3 may be secured to the lower end of the side wall portion 5 by a rolled double seam 6 in the usual manner. The upper end of the side wall portion 5 terminates in an annular, radially outwardly projecting open curl 7, FIG. 2.
The cover member 4 includes a substantially diskshaped central portion 8 from the outer peripheral edge of which an annular flange 9 projects: outwardly. In the assembled container 1, shown in FIG. 1, the flange 9 embodies an arcuate portion 10 which extends outwardly and downwardly around the curl 7, and the flange 9 terminates at its lower edge in a lower edge portion 11 which is disposed in flat juxtaposition to the outer face of the side wall portion 5 below the curl 7, FIG. 2. At the lower edge portion 12 of the arcuate portion 10 of the flange 9, the flange 9 is preferably disposed in underlying, abutting engagement with the lower surface of the curl 7 so that the cover 4 is firmly held against removal from the body portion 2. In the preferred form of the container 1 shown in the drawings, a sealing compound 13 is disposed between the curl 7 and the portion of the arcuate portion 10 of the flange 9 disposed above the portion 12, so that the sealing compound 13 is disposed between the curl 7 and the flange 9 across the entire top and side wall portion of the curl 7, FIG. 2. Preferably, the sealing compound 13 is a somewhat tacky, rubber-like material and may be any one of several suitable sealing materials readily available on the market such as, for
example, a plastisol gasket sealing compound.
Three pull tabs 14, 15 and 16 extend downwardly from the lower edge of the lower edge portion of 11 of the flange 9, to afford integral extensions thereof, FIG. 1, for a purpose which will be discussed in greater detail presently. Score lines 17 and 18, FIGS. 1 and 2, are formed in the flange 9 and extend therearound from one side to the other of the group of tabs 14-16.
A slot 19 separates the tab 16 from the tab 15, FIG. 1, and terminates at its upper end at one end of the score line 17. The score line 17 extends around flange 9 and terminates at its other end at the lower edge of the lower edge portion 11 adjacent to the tab 14 on the side thereof remote from the tab 16, FIG. 1.
Another slot line 20 separates the tab 14 from the tab 15, FIG. 1, and terminates at its upper end at one end of the score line 18. The other end of the score line 18 terminates at the slot 19 in downwardly spaced relation to the upper end thereof, FIG. 1.
The score line 17 defines the upper edge of a tear strip 21, which extends around the cover member 4 from the tab 16 to the termination of the score line 17 at the other side of the tab 14. The lower edge of the tear strip 21 is defined by the lower edge of the lower edge portion 11 of the flange 9. The upper edge of the tear strip 21, in the assembled container 1, is preferably disposed downwardly and inwardly of the radially outermost portion of curl 7, FIG. 2.
The score line 18 defines the upper edge of another tear strip portion 22 which extends from the tab 14, at one end, and terminates at the other end at the junction of the score line 18 with the slot 19, FIG. 1. The lower edge of the tear strip 22 is defined by the score line 17. The score line 18 is preferably disposed outwardly of the radially outermost portion of the curl 7 for a purpose which will be discussed in greater detail presently.
In the assembled container 1, the pull tabs 14-16 preferably aflord vertical extensions of the lower edge portion 11 of the flange 9, and are disposed in substantially fiat juxtaposition to the outer face of the side wall portion of the body portion 2. When it is desired to remove the cover member 4 from the body portion 2, the tab 16 may first be manually pulled upwardly and in a counterclockwise direction around the container 1 to thereby tear the tear strip 11 from the cover member 4 along the score line 17. When this is accomplished, the two pull tabs 14 and 15 remain on the cover 4, as shown in FIG. 3, and the flange 9 of the cover 4 continues to extend below the curl 7 in underlying relation thereto effective to retain the cover member 4 on the body portion 2 in a positive manner.
Thereafter, in the removal of the cover member 4 from the body portion 2, the pull tab 14 may be manually pulled upwardly and around the container 1 in a clockwise direction to thereby tear the tear strip 22 from the cover member 4. After this has been accomplished, the pull tab 15 remains on the cover member 4, as shown in FIG. 4, and the portion of the flange 9 from which the pull tab 15 depends remains in cover-retaining, underlying relation to the curl 7. After the tear strip 22 has thus been removed, all of the flange 9, except the aforementioned portion thereof from which the tab 15 depends, terminates at its lower edge along the score line 18 in outwardly disposed relation to the curl 7, as shown in FIG. 5.
Completion of the removal of the cover member 4 from the body portion 2 'may then be effected by manually pulling upwardly on the pull tab 15 to thereby pull the aforementioned portion of the flange 9 from which the pull tab 15 depends upwardly and outwardly of the aforementioned underlying relation to the curl 7, to thereby release the cover 4 for removal from the body portion 2. Thereafter, by pulling upwardly on the tab 15, the cover 4 may be completely removed from the body portion 2.
With the container 1 constructed in the aforementioned manner, a container embodying a removable, tearstrip type of cover member is afforded wherein a relatively extensive portion of the cover member may be readily removed with relatively little manual effort. With such construction, the cover member 4 in the assembled container 1 may be disposed in relatively extensive underlying relation to the curl 7 in such a manner to insure good sealing characteristics between the cover member 4 and the body portion 2, while enabling the cover member 4 to be readily removed without the use of tools of any type.
Also, it will be seen that, with a container constructed in the manner of the container 1 shown in the drawings, after the cover member 4 has been removed from the body portion 2, it can subsequently be replaced thereon in effective closing relation to the body portion 2. The cover member 4, shown in the drawings, includes a side wall portion 23 which extends between the central portion 8 and the flange 9 in substantially perpendicular relation to the central portion 8. In the assembled container 1, the side wall portion 23 is disposed in frictional engagement with the inner surface of the side Wall portion 5 at the upper end thereof, FIG. 2. This is also true when the cover member 4 is reinstalled in the aforementioned covering relation to the body portion 2, FIG. 5. When the cover member 4 is so reinstalled, the flange 9 rests on the upper face of the curl 7 in such a manner that it would afford an effective support for the cover member 4, even if the cover member 4 did not embody the side wall portion 23.
In those instances where a sealing compound, such as the sealing compound 13 is disposed between the flange 9 and the curl 7 in the assembled container 1, the sealing compound in the upper portion of the flange 9 also assists in retaining the cover member 4 on the body portion 2 when the cover member 4 is reinstalled in covering relation to the body portion 2.
In FIG. 6 of the drawings a container 1a, which constitutes a modified form of the container 1 is shown. The container 1a is identical in construction to the container 1 except for the arrangement of the score lines, the pull tabs, and the slots separating the pull tabs. Parts shown in FIG. 6 which are identical to parts shown in FIGS. 15 are indicated by the same reference numerals, and parts which are similar, but have been substituted for corresponding parts are indicated by the same reference numerals with the suflix a added thereto.
In the container 1a, the pull tabs 14a and 16a are disposed in side-by-side relation to each other, with the pull tab 15a disposed on the side of the pull tab 14a remote from the pull tab 16a. A slot 19a separates the tabs 14a and 16a, and terminates at its upper end at one end of a score line 17a, the other end of which terminates at the lower edge of the edge portion 11 of the flange 9 at the side of the tab 15a remote from the tabs 14a and 16a.
Another slot 20a separates the tabs 14a and 15a, and terminates at its upper end at one end of a score line 18a, the other end of which terminates at the score line 17a in outwardly spaced relation to the tab 15a on the side thereof remote from the tabs 14a and 16a.
Removal of the cover member 4a from the assembled container 1a may be effected in substantially the same manner as that heretofore described with respect to the removal of the container 4 from the container 1 shown in FIGS. 1-5. In this instance, the pull tab 16a may first be pulled upwardly and around the container 111 in a counterclockwise direction to thereby remove the lower tear strip 21a. Thereafter, the pull tab 14a may be pulled upwardly and around the container 1a in a counterclockwise direction to thereby remove the tear strip 22a. Completion of the removal of the cover member 4a may then be effected by pulling upwardly on the pull tab 15a to thereby pull the adjacent portion of the lower edge portion 11 of the flange 9 outwardly from latching engagement under the curl on the body portion 2, and lift the cover 4a from the body portion 2 of the container 1a.
From the foregoing, it will be seen that the present invention affords a novel container construction which is particularly well adapted for use in the manufacture of cans, and the like. However, as will be appreciated by those skilled in the art, such construction may also be used in the manufacture of other containers such as, for example, jars, and the like, wherein the body portion 2 is made of glass or other suitable material, and the cover members 4 or 4a are made from a suitable sheet material such as, for example, the aforementioned aluminum or tin plate, and the like.
Also it will be seen that the present invention affords a novel container having a cover member of the tear-strip type which may be readily removed from the body portion of the container. I
In addition, it will be seen that the present invention affords a novel container of the aforementioned type wherein the cover member thereof is so constituted and arranged that, after it has been removed, it may be again reinstalled in practical, effective covering relation to the body portion of the container.
Also, it will be seen that the present invention afiords a novel container which is practical and efficient in construction and operation, and which may be readily and economically produced commercially.
