comBINED CAN AND OPENER.

Application filed June 16, 1926. Serial No. 116,392.

Our invention has for its object a can formed, rolled and sealed and provided with a flanged portion for frictionally engaging and holding an opener or key member adapted to open the said can.

Another object is a can of the character described in combination with the said-key or opener.

A further object is a can adapted to retain its contents under a vacuum or pressure and which may be readily opened by the user leaving the severed portions, namely t e body of the can and cover, or top, so that the two parts will frictionally engage, without any accessory .means, and thus enable the top to be employed as a cover to retain pure and out of contact with the air, the partially used contents. One of the end portions, as the bottom or top of the said can being provided with a frictionally engaging portion to grip an opener or key member. The said member is adapted to open the said can and is thus mounted in combination therewith.

A further object is a can of the character described in which the cover engages frictionally with the body portion and is initially sealed to the body portion by a double seam and which may be opened by employing a key member engaging a tearing strip around the body and immediately ada jacent to the cover double seam, after which may be can having athe two parts, that is the cover and the body, frictionally engaged to cover the can during the use of the contents at intervals, the top of said can being provided with a frictionally engaging flange portion'to grip and hold the key or opener, in combination with said member.

Another-object is a can of the character described, adapted as a package for vacuum coffee, the top of the said flanged portion constructed and adapted to frictionally grip and hold a removable key or opener for opening the said can. .Also such a can in combination with the said key or opener. 7

Other objects will appear from the'drawingrand specifications which follow:

packed ground hese objects we accomplish bytpressing rolling or otherwise forming one of the end portions and preferably the top of the can,

with a flanged portion over which or within which a key or opener is adapted to fit.

Frictional engagement is attained between the flanged portion and the key, by forming the key of suitable material and shape so that it will spring into or out of engagement with the said flanged portion.

The key is employed by the user by being lifted from frictional engagement with the flangedportion and thereafter engaging a known as herring bone scorings, thus pro-" viding a narrow tearing strip in the can body'immediately adjacent the double seam by which the cover or top is attached.

The cover of the can we prefer to flange inwardly and which frictionally engages with a peripheral internally projecting bead in the body portion, and after the tearing strip is removed the top or cover may be depressed so that any part of the flanged portion engages frictionally over the inner periphery of the said bead, as set forth in copending application Ser. No. 109,502, filed May 17, 1926, to which reference is herein made.

By referring to the accompanying drawing, our invention will be made clear.

Fig. 1 is a cross section through an upper portion of a can employing our invention and along the line II of Fig. 2.

Fig. 2 is a cross section of the cover of Fig. 1 on the line IIII thereof.

Fig. 3' is an alternate form of our invention and showing the can top and body portion after the tearing strip has been removed, and is on the line IIIIII of Fig. 4.

Fi .4 is a cross section of Fig. 3 on'the line %V IV thereof.

' Fig. 5 illustratesthe scoring lines and herring bone scoring of the'tea-ring strip.

Fig. 6 is a fragmentary side view of a can to show the manner in which the key or opener engages the tearing strip.

Throughout the figures similar numerals refer to identical parts.

A can body is shown by the numeral 1, to which is sealed the bottom 2, along the double seam 3.

The top is shown at 4 double seamed at 5 to the body portion 1 and is provided with the inner flanged portion 6, normally in frictional engagement with the internal projecting bead 7 in the body portion 1.

This bead presents an inner convex surface against which the outer surface of the flanged portion 6 frictionally engages.

At 8 and 9 are conventional score lines in the body of the can material between the bead 7 and the seam 5.

At 10 is a tongue projecting from the tearing strip 14 over which the key or opener is adapted to initially engage as indicated in Fig. 6.

Between the score lines 8 and 9 are the herring bone scorings 12-12, to insure the tearing along the lines of the scorings 8, 9 when the key 13 is employed to wind and therefore tear the strip 1 1 from the body portion 1.

When the key 13 has been wound about the periphery of the can, the tearing strip 14 will have been removed completely around the upper portion of the body between the bead 7 and seam 5, leaving the parts in the position shown in Fig. 3, with the top freed from the bottom but in frictional engagement between the flanged portion 6 and head 7, all as set forth in the above mentioned co-pending application.

Our present invention is directed particularly to the key or opener and its combination with the can, and this we accomplish by pressing, rolling or otherwise forming in a portion of the can and preferably in the top portion thereof, a circular flanged portion either extending upward or downward from the surface of the can.

In Figs. 1 and 2 the key or opener is illustrated as fitting into a flanged recess in the top of the can, whereas in Figs. 3 and the opener is shown as being sprung over and held in frictional engagement with an upstanding flanged portion of the top of the can.

When the top of the can of Fig. 1 is being formed, the annular recess 20, is formed therein with the overhanging projecting edge 21. The key or opener 13 is formed of spring wire and has an engaging portion at 22 WhICh normally seats under the projecting edge 21 and within the recess 20, the other end 23 of the key 13 engaging under the A projecting edge on the opposite side of the annular portion 20.

The key may be removed by slipping the finger under the body of the key for which purpose the recess 24 is provided.

Referring particularly to Figs. 3 and 4 an upstanding circular [lunged portiou is shown provided in the cow-r at 30.

This has an annular peripheral recess 31. with an overhanging extending edge 32.

The key adapted to this form of flanged can is shown at 33 having a circular linger grip portion 3 1 which is adapted to engage within the recess 31 and under the overhang ing edge and due to the spring material at 34 which is initially wound to a slightly smaller circle than that of recess 31, springs over the edge 32 and into place within the recess 31 and is there held frictionally until such time as the user desires to open the can when the key is removed by grasping the projecting shank portion and pulling it over the edge 32.

lVith either form of can or key there is available at once, when the can arrives in the hands of the user, an opener freely and readily removable from the can which may be employed to remove the tearing strip about the periphery and thus open the can.

Special attention is drawn to the form of the key 13 which is made up of spring wire bent in its shank portion, providing the loop 26 adapted to engage the tongue 10.

WVhile the finger recess 2a is shown in Figs. 1 and 2 as immediately under the center or body portion of the key it will now be apparent that this recess may be of greater diameter and concentric with the flanged portion so as to extend out and under the finger gripped portions of the key as indicated by the dotted circle 27 if desired, in which case the key may be gripped under the spring end 28 to remove it from the recess or a finger depression may be made in any portion to suit the taste and requirements of individual makers.

\Ve claim:

1. In a can adapted to be opened by a finger operable key, a flanged portion having an annular recess with an overhanging edge flanged from the can material and adapted to receive and to frictionally hold a finger operable key, said flanged portion depressed in an otherwise flat part of said can, and a finger space further depressed in and below the bottom of said recess.
