SEAL FOR CAN COVERS.

Application filed December 17. 1924.

This invention relates to seals for can covers, and has for its object to provide an improved seal which may be attached to the can cover so as to securely seal the can cover to the can and give evidence by the untampered condition of the seal that it has not been tampered with. At the same time the object of the invention is to provide such a seal that it may readily be broken by the opening of the can cover by the user, simultaneously with the opening of the can cover or by some suitable instrumentreadily breaking the seal.

For this purpose, my invention consists of the structures hereinafter pointed out in the claims, embodiments of which will be described in the annexed description and shown in the annexed drawings.

In the accompanying drawings Figure 1 shows a side view of my improved seal as applied to a can top;

Fig. 2 is a plan view thereof;

Fig. 3 is a section taken on line 33 of Fig. 2;

Fig. 4 is a section taken on line 4-4 of Fig. 2;

Fig. 5 is a side View of the seal itself I before it has been applied to the can top;

Fig. 6 shows a portion of the seal in perspective, showing the character of the break after the seal is broken;

Fig. 7 is a side view of another embodiment of my invention;

Fig. 8 is a perspective of the seal breaking as the cap is being removed, and

Fig. 9 is the seal removed from the cap, showing the nature of the tearing along the scored portions.

Similar characters of reference designate corresponding parts throughout the differentviews.

Referring to the drawings, and more particularly to Figs. 1 to 4, there is shown a can of well-known manufacture indicated by 10, which forms no part of my invention, and this can is provided with a neck portion 11, which in general construction is also well known, but the improvement I provide on such necks is to have the exterior contour arranged on a straight line alignment in that the portion 12 as shown in Fig. 3, is in substantially the same perpendicular line as the portion 13. This alignment of these portions 12 and 13 permits what is known as a discharging spout, not shown in the drawings, and of well known construction,

to be readily applied to this improved form of neck which is possible by virtue of the perpendicular alignment of the parts 18 and 12. From the part 13 the neck portion is inclined inwardly as shown by 14, and this readily permits the closing cap for the neck to be applied thereto.

This closing cap for the neck has diametrically oppositely arranged depending members 15, and when this closing cap is applied, one of these depending members is inserted beneath the shoulder 13 into the indentation 16 of the neck and the other depending member may then readily take a similar position by being slid. along the inclined surface 1-1 of the neck. Interposed between the cap 17 and the neck of the can is a layer of paper or the like indicated by 18, and this layer is tightly compressed by means of a bead 19 against the uppermost edge of the neck 20.

Surrounding the cap 17 is arranged my improved seal 21 which is made of a suitable metal suflicicntly stiff to have the mo essary rigidity, but of such a character that it may readily tear particularly when tearing indications by partial incisions are provided therein. Such partial incisions are indicated by 22 in Fig. 5. These incisions do not pass through the metal of the seal. but only indent the metal but so effect the molecules thereof so that when a tensioned force is exerted in the portion indicated,

for instance at 23, the leg 24 will tear apart and the lines of cleavage will follow these indentations. The Y-shape is particularly adapted for this purpose and the line of cleavage and tearing function is clearly indicated by Fig. 6. This seal is applied to the cap 17 as stated and when it so surrounds the cap the lower edge of the seal is bent inwardly as indicated by 25 in Fig. 3, which serves to hold the seal securely around the cap. This bent in portion 25 can only then be removed from the cap after the seal is broken.

The cap can be readily removed with its seal by inserting a suitable instrument under the depending portions 15, whereby the indentations 22 will be torn apart as indicated in Fig. 6, or any instrument can be applied along any portion of the bent in part 25 and again the cleavage will take place as shown in Fig. 6.

It will be particularly noted that the leg 24 of the indentations does not go down to the edge of the seal but a portion of the metal is left unharmed by indentations,

In Fig. 7 I have shown an indentation 27 which extends from the uppermost portion 28 of the seal and shown close to the lower edge 29 of the seal, but does not extend to the very edge thereof leaving; a portion of the metal 80 in place.

The Yshaped indentation or scored portion, enables the seal or band to stretch quicker, and also open along two scored portions, in contrast to the strtight line score of Fig. 7. The ii shaped score renders an easier disengagement. Y

I have shown various embodiments of my invention, but it will be clearly understood that I do not wish to be limited to the specific constructions, but that changes may be made therein without departing from the spirit of the invention as defined in the ap pended claims.

I claim:

1. The combination with a cover for re ceptacles comprising a cap adapted to be fitted over the mouth of the receptacle and having integral clamping devices for on gagement with the shoulder of the receptacle wall; of a seal therefor comprising a sleeve like cylindrical member fitted snugly over the outer circumferential surface of the cover cap and having an upper internal portion engaging the above upper surface of the cover and a lower internal flange engaging the lower clamping crevice of the cover, so as to become axially immovable, and having further a weakened portion along its cylindrical circumferential part, but leaving a strip of unweakened metal around its lower flange so as to be adapted to cling fast to the cover cap if the latter is fixed in the right position on the receptacle but to be torn through the unweakoncd metal strip and along; the weakened portion as soon as the cap is distorted by being taken off the receptacle.

2. The combination with a cover for re ceptacles comprising a rap adapted to be fitted over the mouth of the receptacle and having integral clamping devices for engagement with a shoulder on the receptacle wall, of a seal therefor con'iprising a metallic sleeve fitting over the outer periphery of the cover cap, the intermediate section between the upper and lower portions thereof having a weakened portion adapted to break during the removingof the cover cap from the mouth of the receptacle, due to the slight distortion of the cap. and the cap thereafter being applicable for covering the receptacle without said sealing sleeve.

3. The combination with a cover for re ceptacles comprising a cap adapted to be fitted over the mouth of the receptacle and lessees the lower clamping; devu oi the Coven the lower inturned flange or the seal being; formed integral and having a plurality of diverging weakened port ons e7 tending; therefrom formed hy partial inci sions in the cylindrical portion of the seal whereby the seal will break during the removing of the cap from the mouth of the receptacle, due to the slight distortion of the cap, and the can thereafter being applicable for covering; the receptacle without said sealing: sleeve.

4;. The combination with a receptacle cover having a periphery adapted to be outwardly deformed during removal, of a seal cont st ing of a ring of angle cross section fitted snugly over the top and periphery of the cover, the peripheral part of which ring; has a plurality of weakened oortions adapted to be broken by the slight deforming of the seal through the primary deformation of the cover duringthe operation of moving; the cover from the rcceptaclcb said \YQZlltened portions extending; close to the lower edge but leaving an annular portion of unweahened metal around the lower rim of the peripheral part of the seali so that on the rupturing of the unwcalrened metal the rupture takes place along the weakened por tions.

5. The combination with a receptacle cover having a periphery adapted to he outwardly deformed during removal, of a seal, corsisting of a ring; of anpgie (eras section fitted snugly over the top and periphery of the cover, the peripheral part of which ring has a plurality of weakened por tions adapted to be broken by the slight deforming: of the seal through the primary deformation of the cover during the operation of removing: the cover from the receptacle, said weakened portions forming the shape of a Y and extending; close to the lower edge but eavinoj an aunular portion of umvealtened metal extend inn over and bent around the rim of the covering, in combination with :i prolonoat inf; flap at the lower rim of too covermpy extending beyond the lower edge of the seal ring. and adapted to as a grip for forcing the cover off from the receptacle In testimony that I claim the foregoing: as my invention, I have signed my name hereto.
