OPENING ATTACHMENT FOR CANS OR VESSELS- SPECIFICATION formingpart of Letters Patent No. 758,152, dated April 26, 1904.

Application filed March 16, 1903. 7 Serial No. 143,105. (No model.)

To all whom, it 17mg concern.-

Be itknown that I, SETH L. SHELDON, a citizen of the United States of America, residing at the city of Ithaca. in. the county of Tompkins and State of New York, have invented certain new and useful Improvements in Opening Attachments for Cans or Vessels, of which the following is a specification.

This invention relates to improvements in cans and similar vessels for packing and storing, and is more especially directed to an at tachment therefor designed to facilitate the opening of cans to which the closures thereof are sealed with a hermetic joint.

The object of the present invention is to provide an attachment of the character mentioned which may be applied to cans or similar packing and storing vessels with but slight cost and by the use of which the joints between the bodies of the vessels and the closures may be readily opened to enable removal of the closures without the necessity of cutting the joints or by the employment of anyimplement other than the attachment.

A further object of the present invention is the provision of an opening attachment which while the vessel is sealed forms a permanent part thereof, and thereby prevents loss of the attachment, but which may be readily detached and discarded from the can or other vessel supplied therewith immediately upon the vessel being opened.

A further object of the present invention is the provision of an opening attachment which is so applied to the can as to open the same with a minimum degree of effort and which is designedto efiect the opening of the joint between the body of the vessel and the closure without defacing or injuring the appearance of the closure, thus enabling the latter to be subsequently used with the vessel for closing the same.

(Vith these general objects in view and others which will appear as the nature of the improvements isbetter understood the invention consists, substantially, in the novel construction, combination, and arrangement of parts, which will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claim.

While the forms ofthe invention herein I shown and described are what are believed to be preferable embodiments thereof, it is to be understood that the same are susceptible ot" tion of a can provided with an opening attachment constructed in accordancewith the present invention. Fig. 2 is a'vertical transverse sectional view thereof. Fig. 3 is a top plan view of a can, illustrating another form of application of the herein-described invention. view of the form shown in Fig. 3.

Referring to the drawings, the numeral 1 designates the body of acan which is of the ordinary construction; but the rim of said body I is provided with a circumferential groove 2, the latter being formed in said rim in any suitable manner.

The numeral 3 designates an ordinary cover applied to the can-body 1 and extending over Fig. 4 is a vertical transverse sectional the rim of the latter to a sufficient extent to 1 and the cover 3. As before premised,it is the object of the present invention to provide means for opening the joint referred to without the necessity of defacing'or impairing the can" orwithout the employment of knives for cutting'the same, as is usual. To this end a releasingstrip 4t, preferably in the form of wireQeilthough any other form may be. employed, is seated in the groove 2 and surrounds the rim of the body 1, and the end of said strip 1 is passed through a perforation 5, formed in the rim of the body 1" adjacent to the groove 2, and is bent to form a book 6, whereby the inner end of the releasing-strip 4 is securely held in engagement with the rim of the body 1, but by which said strip may be readily detachable and discarded from the can-body when the joint has been opened.

through and is seated within a groove 7,formed in the outer side of the body 1 and extending obliquely to the .plane of the groove 2, and said groove 7 terminates in a substantially elliptical groove 8, which is also formed in the outer side of the body 1 in order to receive a finger-loop 9, formed at the outer extremity of the strip 4. Through the medium of the grooves 7 and 8 and the fact that the extremity of the releasing-strip 4 is seated within said grooves it will be seen that said extremity lies beneath the surface of the canbody and does not, therefore, interfere with the application of labels to said body. Moreover, the sealing medium effectually holds the extremity of the strip 4 Within the groove 7, thus preventing the entrance of air through said groove and at the same time preventing removal of the extremity therefrom. When it is desired to open the joint, the finger-loop 9 is removed from the groove 8 and by applying pressure to said loop and pulling thereon that portion of the strip within the groove 2 is gradually pulled from said groove, which effects breaking the hermetic joint, and this is continued until the joint around the entire circumference of the can has been broken, whereupon the cover 3 is free to be'removed from the body 1. When this has been accomplished, the purpose of the releasing-strip 4: has been fulfilled, and through the detachable connection of the inner end, by means of the hook 6 and theperforation 5, said strip may be readily detached from the can-body and discarded. It will thus be seen that the joint between the cover and the body is broken in a neat manner and without in any degree defacing or impairing the appearance of the can or the utility of the cover 3, and the latter, therefore, may be subsequently used for closing the can-body.

In Figs. 3 and 4 is shown another application of the releasing-strip I, and referring thereto it will be observed that the cover 3 in lieu of being applied to the exterior of the can-body l is set within the mouth thereof, and the rim of said cover is provided with a circumferential groove 10, in which the releasing-strip 4: is seated. As in the form shown in Figs. 1 and 2, the inner end of the strip ipasses through a perforation 11, formed in the rim of the cover 3, and terminates in a hook 12, while the outer end of the releasingstrip 4 passes through an oblique groove 13, also formed in the rim of the cover 3, in order that the extremity of the strip 4 may project at the outer side of the can. This extremity terminates in a finger-loop 14:, which finger-loop, if desired, may also be seated in a groove of corresponding shape as in Figs. 1 and 2 in order to depress the finger-loop beneaththe surface of the .cover 3. form it will be noted thatthe releasing-strip i occupies a position between the can-body 1 and the cover 3, immediately beneath the joint therebetween, and by grasping the finger-loop 14 and exerting pressure thereon it will'be seen that the body of the strip 4: may be readily drawn through the joint, severing the same and releasing the cover 3 from its sealed relation to the can-body 1. As in Figs. 1 and 2, after the joint has been broken the usefulness of the strip 1 has terminated, and this may be readily detached from the cover 3 by removing the hooked end therefrom and the strip may then be discarded. This does not afi'ect the appearance of the can body or cover, and the utility of the latter for closing the can-body is still preserved.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

The combination with the body of a can or similar vessel, and the closure thereof, one of said elements having a circumferential groove provided with a perforation, of a releasing-strip seated in said groove and having a hook at its inner end which engages the perforation of said groove, whereby the inner end ofsaid strip is detachably held, the other end of said strip projecting between the body In this and closure to the exterior of the can and seated in a groove formed in the exterior of the side of the can and extending obliquely to the plane of said circumferential groove, said end terminating in a finger-loop, the side of the can being also provided at its exterior with a groove corresponding to the shape of said finger-loop and communicating with the oblique groove, the finger-loop being seated in said groove to position said loop and the extremity of the releasing-strip beneath the surface of the side of the can-body and thereby not interfere with application of labels to the body.

In testimony whereof I hereto affix my signature in presence of two witnesses.

SETH L. SHELDON.
