CAN AND SLIP COVER Filed Nov. 2, 1928 Patented June 17, 1930 PATENT OFFICE f EDWARD HILDEBRANDT, OF TACOMA; WASHINGTQN CAN AND SLIP COVER Application filed November 2, 1928. Serial No. 316,863.
My invention relates to an improvement in cans, and has for its main object the provision of a .can and cover which may besecurely sealed, yet which, after opening,
leaves the can with a slip cover, both cover and can body being reinforced-at the edges, and these dges being withoutrough edges or portionsto catch on articles, or to cut the hands of those who handle them, or at least, with the rough edges so protected that they can do no damage.
It.is anobject to provide a can of the character described, which may be sealed with compound, and which may be opened by means of a tear-off strip, yet having the advantages as to stifiness and smoothness of the edges of both can body-and cover flange referred to above.
A further object is the provision of a can and cover of this general character which will be convenient and economical to manufacture.
It is a further object to provide a key for such cans which may be semi-permanently associated with the tear-ofl strip, so that it is always in condition for use, yet carried in such a position that it does not interfere with the packing and stacking of the cans.
My invention comprises the novel conso struction shown in the accompanying drawings, described in the specification, and particularly defined by the claims terminating the same.
In the accompanying drawings I have shown my invention embodied in several forms embodying the underlying basic idea.
Figure 1 is an elevation of my improved can as it would appear ready for shipment.
The remaining figures are axial sections along the line of the key tab, Figure 2 showing parts assembled but not secured together, Figure 3 showing parts secured together, Figure 4 showing parts in the relation they would occupy after the tear-off strip has been removed, and Figure 5 showing the cover and can body separated after removal of the tear-off strip.
Figures 6, 7 and 8 are similar axial sections through one side of a modified form, Figure 6 representing parts assembled but strip 5 these means serving to reinforce the upper edge of the final can body, and to provide a smooth edge therefor. Similarly, the cover resulting after the tear-ofl' strip has been removed is left with a reinforcing seam or bead, which also protects against .any rough or sharp edges. It is immaterial whether the tear-off strip employed be formed originally as a part of the can body or as a part of the flange of the cover, and both forms are shown herein. There is, of course, a seamed or like permanent securement between the can cover and the can body, but it is not material whether this seam be formed above or below the tear-off strip. In efiect, the tearofi strip is united at its top edge, permanently or by a seam, with the cover flange, and is united in one 8o 05 these ways to the can body at its lower e ge.
Proceeding first to a description of the forms shown in Figures 2 to 5 inclusive, it will be noted that the cover 1 is formed with 35 a depending peripheral flange 10, and that the can body 2 has secured to its upper edge and projecting thereabove a separate collar 3. terminal bead 4 is formed about the upper edge of the collar 3 in this instance, inasmuch as this collar is in effect a portion of the body in this form, and this bead4 therefore forms the upper edge of the can body, and reinforces this upper edge and renders it smooth. Below the upper edge of the can body 2 there is formed a tear-01f provided with a tab 50 for engagement by a key 6, which key is shown only in Figure 1. To secure the several parts of the can together a seam is formed at 23 be- 10 tween the can body 2 and the collar 3, thisoif strip-is removed the false seam 12' still being located at-the lower edge of the tearoif strip 5, and a bead 12 is formed between the flange 10 of the cover and the upper edge of the can body 2, this being located preferably immediately at the upper edge of the tear-off strip 5.
These seams 23 and 12, or the latter seam alone, in this particular form, may be filled with sealing compound, and the package may thus be made hermetically tight. Removal of the tear-off strip 5, as is indicated in Figure 4, leaves the cover 1 with its flange l0 and the seam 12 defining its lower edge, free to be removed from the can body which now includes the collar 3 and its bead 4 forming its upper edge, and when this removal is effected, both the can cover and the can body are left with reinforced free edges, and these edges are smooth. The remainder of the tear-off strip, which is located at the bead 12, is within and protected by the bead, and being short, is not likely to catch or to cut.
Whereas, in the form just described, the bead 4 was formed in a collar forming in effect an upward extension of the can body,
the can body itself cooperating with and being secured to the flange of the cover, which flange lies outside of this collar, it is possible to form the bead 4 in the metal of the can body itself, as is shown in Figures 6, 7 8 and 9, and to form the tear-off strip in a separate collar 30, which may be attached outside of the can body near its upper edge. Thus the collar 30 carrying the tab 50 is seamed at 23 to the can body 2, and at 12 to the can top, or rather to its depending flange 10. Sealing compound may be employed at both seams, or at either one alone. Now, when the tear-off strip 5 is removed, this breaks connection between the two edges of the collar 30, one of which is retained in the bead 23, and the other in the head 12, as is best seen in Figure 7, and the cover 1 may be removed, still carrying the bead 12 as a reinforcing and protective means, and the small portion of the collar retained by the bead 23 is not liable to do any damage. Further, the top edge of the can body retains the protective and stiffening bead 4. It will be noted that the seam 23 in this form is an internal seam, whereas in the previous form it was an external seam, but this is immaterial.
The collar 3 may be omitted entirely, if desired, and such a construction is illustrated in Figure 9. In this form the flange 10 is extended downward, and the tear-off strip 5 is incorporated in this extension. A false seam 12 is formed in this flange 10 just above the upper edge of the tear-oil? strip 5, and the lower edge of the flange is seamed to the bod 2 at 23, below the lower edge of the tear-o strip 5. When the tearforms a stiffening reinforcement at the lower edge of the can cover flange, also protecting against a sharp edge, and the bead 4, as befonfistiffens the upper edge of the can body itse While the usual keys may be employed in association with such a can, I prefer that a key be employed such as that shown in Figure 1. This key is provided with the usual shank and head 61, and a slot 62 extends from the shank into the head. Through this slot 62 is passed the tab 50, and the key may he slid lengthwise of itself on this tab. Norm ally it may be kept in the lowered position, as shown in full lines in Figure 1, and when it is desired to tear off the strip 5 the key may be slid to the dotted line position of Figure 1, where it is immediately ready for use. This is done without any detachment of the key and subsequent attachment to the tab, and it is thus unnecessary to anchor the key in any permanent manner to the can.
What I claim as my invention is:
