The present invention relates to sheet metal containers or cans adapted to be opened by pressingj'a scored portion inwardly and has particular reference to such a container or can having means for shielding the raw edge of the opened portion andl for reclosing the opened portion.
An object of the invention is the provision of a container or can wherein the raw edge left by pressing inwardly a scored portion of the can to provide a dispensing opening therein, is shielded to protect the consumer against injury when opening the can.
Another object is the provision of such a container or can wherein the raw edge shielding means has the additional function of serving as a reclosure element for the opened container or can.
Another object is the provision of such a container or can wherein the shield and reclosure may be made as a unitary structure which is economical and efficient and readily attached to a container or can. f
Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.
Referring to the drawings:

As a preferred and exemplified embodiment of the instant invention Figs. 1, 2 and 3 of the drawings illustrate a conventional rectangular shaped can having rounded corners' and used for hold- 5 Claims. (01.22977) orzngerof the' consumer.
ing condiments, granular substances or other dry materials including cocoa, dried milk, ground or bean coiiee'la'nd the like. The can includes a iibre body I;I having a metal countersunk panel bottomwIZ and a, similar metal top I3 secured thereto'in suitable end seams I4. The countersunk' panel of the top member I3 is formed with a..ourvedorzsemi-circular score linev I5 which defines a curved or semi-circular.depressible area lwliich is readily broken and bent downwardly andin'wardly into` the can yby pressure of a thumb When so depressed the area I6 breaks away along the score line I5 andbendsfialonga line connecting the terminal en`dsofthe"curved score line; and thus forms a dispensing opening I1r for the contents of th caniasbest. shown in Fig. 3.
Provision is'made for protecting the consumer against'injury from the raw curved edge which remains in the top I3'when the metal of the top is broken along the score line I5 during the opening of the can. For this purpose" the top of the can'fislf'providedr with an overcap 2l made of fibre' or `other suitable, preferably soft material. Thisvercap functions as a shield 2I which lies flat'against the sheet metal top I3 on its outer surface. f This shield preferably is the same shape asthe' top of the can and just large enough to t within its sunken panel. Along the straight portions of the top, the top end seam I4 may be crimped-` finwardly to form retaining lugs 22 which ,projectover the edges of the shield as shown in Figs. 2 and 3 and retain the shield or overcap against displacement.
'Above-fthe Vdepressible scored area I6 in the top I3, the shield 2I is out through along a curved line Aof severance 24 whichy is adjacent but spaced inwardly from the score line I5 in the top member, so that an overlapping ledge 25 of the shield projects Aover and thus shields the sharply severed edge. The ends of the curved line of severance k24 in the shield preferably terminate adjacent Athe terminal ends of the score line I5, and are yconnected by a straight ycrease line 26 which; together with the line of severance 24 deneareclosure flap or member 21 which is hingeable" upward1y along the crease line. The crease line 26 thus constitutes a hinge for the reclosurev member. lA lifting tab 3| secured by a wire staple"32` to the reclosure member 21 may be providedfor easy lifting or hinging of the reclosure member into an open position as best shown vin Fig. 3.
Thus when it is desired to open the can, the. reclosure flap 21 is first raised or hinged into an 3 open position by pulling on the lifting tab 3| as shown in Fig. 3. This provides an opening in the shield which exposes the depressible area I6 in the can top member |3 so that this area may be broken inwardly to provide the dispensing opening l1. Since the score line is disposed or hidden under the' ledge 25 of the shield 2| beyond the defining line of severance 24 of the reclosure ap 21, the sharp raw edge which results from the breaking of the score line is out of reach and the fingers of the consumer are thereby protected against injury therefrom. After a partial dispensing of the contents of the container by spoon or other tool, or by pouring, the
reclosure flap 21 may be returned to its normal closed position in the shield opening as shown in Figs. 1 and 2 and thereby reclose the container for storage.
In some cases it may be desirable to omit the reclosure fiap 21 from the shield. In such cases the shield may be made shorter, as indicated by the dot and dash line 35, and slideable along the top of the can. Such a shorter shield would be provided with an opening, which is movable into and out of register with the dispensing opening |1, the effective registrable openingof the shield being smaller than the dispensing opening of the inner top in order to shield the raw edge of the dispensing opening.
In the modified form of the invention as shown in Figs. 4 and 5, the shield 2| is applied to a round can comprising a sheet metal body 4I having a sheet metal countersunk top 42 permanently attached thereto by a suitable interfolded end seam 44. As in the preferred form of the invention, the top member 42 of the round can is formed with a curved or semi-circular score line 45 which defines a depressible area 46 which is breakable or bendable downwardly and inwardly into the can to provide a dispensing opening.
In this round can, the shield 2| with its protecting ledge and hingeable reclosure flap 21, is circular in shape to fit the can and is disposed in the countcrsunk panel of the top 42 as in the preferred embodiment. The shield is retained in place by a plurality of inwardly bent lug portions 48 of the top end seam 44, which project over the peripheral edge of the shield.
In order to prevent rotation of the shield 2| relative to the can top 42, the can top is formed with a locating bead or projection 49 which is struck outwardly from the can top at a place opposite the depressible area 46 and which extends up into a locating aperture 5| formed in the shield. The engagement of the bead 49 in the aperture 5| maintains the reclosure flap 21 of the shield in proper register with the depressible area 4S in the can top 42.
As in the preferred form of the invention, the reclosure element 21 of the modified form of the shield 2| is raised to expose the depressible area 46 in the can top 42 so that this area may be forced inwardly to provide a dispensing opening for the can. In this modified form also the score line 45 is covered by the ledge 25 of the shield and thus the sharp raw edge which results from the breaking of the score line is out of reach and the hand of the consumer is thereby protected against injury therefrom. In this can 'the reclosure fiap 21 may be returned to its original closed position for reclosing the vcan for storage.
A further modified form of thevinvention as shown in Figs. 6 and 7 discloses av can similar to that shown in Figs. 4 and 5 and having a shield or overcap 55 which is provided with an opening 56 of similar contour to that of the depressible area 46 in the can top, but of slightly smaller dimensions. There is no reclosure flap on this shield. The shield lies fiat against the can top and is rotatable thereon to move the opening 56 into and out of register withthe depressible area 4S. The end seam of the can is curled inwardly over the shield to retain it in place. Since the effective registrable opening in the shield is slightly smaller than the depressible area 48, the shield thus overlaps the score line 45 when the opening 56 in the shield is in register with the depressible area and hence the raw edge left by the breaking of the score line when the depressible area is forced inwardly, is covered to guard against inflicting injury on the consumer.
It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
