Description

May 24, 1932. w. F. PUNTE' EASY OPENING CONTAINER Filed June 28, 1950 ,wwwm i Patented May 24, 1932 UNITED STATES WILLIAM F. PUNTE, or SYRACUSE, NEW YYORK, ASSIGNOR r0. CONTINENTAL C N COMPANY, INC., OF NEW YORK N. Y., A CORPORATION OF NEW YORK v EASY OPENING CONTAINER Application filed June 28,

An object of theinvention is to provide a means whereby an inserted collar may be bonded to the metal wall of the container by solder which is applied so as to be covered and protected from contact with the food products in the container, and which is applied in such a way as not to injure the lithographing on the outer face of'the container. In the drawings which show by way of illustration one embodiment of the invention:

Figure 1 is a vertical sectional view through the upper portion of the container embody ing the improvements.

Figure 2 is a view through a portion 0 the container showing the rip strip removed and the end lifted from the container.

Figure 3 is an outer face view of a portion of the reclosure ring. y

The invention is used for securing an inserted reclo-sure collar to the body of the container. As shown in the drawings the container body is indicated at l, and one of the ends is indicated at 2; This end is secured to the body of a double seam 3. The body wall is provided with an in wardly projecting bead 4 and with

score lines

5 and 6 which form a rip strip 7. Located within the body of the container is an inserted reclosure collar 8 which is attached to the body of the container. There is also an inserted reclosure collar 9 attached to the end so collars are preferably made from metal by' rolling or drawing the metal so as to provide a smooth unbroken edge for the collar as dis tinguished from a cut or torn edge. The collars formed in this way and arranged as flameter,

shown in the drawingsform no part {of the present invention, but are shown 'andf'described and claimed in my co-pending application 465,742filed July 3,1930. The pres Kent invention is directed particularlyv to means for securing this collar8 to the body of the container. This collar when inserted in the body 'is directly above the bead 4, but

is not many way attached to the'bead. The

beadiserves as a support for preventing the collar from being forced into the container by-the pressure applied'to the outer edge 7 thereof. In the form of the invention shown in the drawings the collaris provided with an inwardly projecting bead 10 which forms 'a recess 11 in the outer face of the collar. This recess preferably extends all the way around the collar. 1 Again as illustrated in the drawings the recess 11 isprovided with a soft solder 112 which is located at spaced in"- tervals." The entire bead may be filled with oven raised to a temperature of about 250 F.-, v and this will cause the solder .to melt and adhere to theinner wall of the body of the This is a temperature below the teniperat-ure that willinany way'aifect the lith- I ographingon the outer'face of the can." The soldenbeing placedibetween the outer faceof the collar and the inner face of the container is covered by the collar so that food products within the container will not come in contact with the solder. Asnoted, the "solder is apin the container and placed against the'bead 4 in the body wallof the container.

The

' plied to the collar, the collar is'then inserted. C 9'0 container body is then passed through an oven heated as stated, and this causes a bond of solder tobe formedbetweenthe collar and the innerymetal' wall of the container body. The ends of the collar are preferably abutted so that the collarfis of uniform diand also of uniform thickness throughout. 1

While I have described the] collars as loo formed'by a rolling or drawing of the metal, it will be understood that it may be formed in other ways without departing from the spiritof the invention as set forth in the appended claims; It will also be noted that the solder as shown is applied at spaced points in the recess. While this greatly saves in the amount of solderused, it will be understood that the solder may be applied in other ways,

the essential feature residing inthe placing of the solder between the collar and the wall of the container andthe use of a solder Which u can be melted to form the bond joining the collar to the bodywithout injuring the litho- Y graphing on theouter face of the container. 7' 7 Having thus described the invention, what 7 .is claimed as new and'desired to be secured by Letters Patent, is V r v i lfAn easy opening container having score Y lines inthe body adjacent one endthereof forming a rip strip, a reclosure collar dis- I posed within said container body, said collar having an'inw'ardly projecting bead formed 1 therein adjacent its lower edge and providing j a recess on its outer face, said recess having soft solder applied therein, whereby when the collaris inserted in the container bodyand 1 heat applied thereto said solder will'form a 2. Aneasy opening container having score bond between the collar and the container for securing the'collar therein;

lines in' the body adjacent'one endthereof forminga rip/strip, a reclosur-e collar disposed within said container, body,'said collar having an inwardly projecting bead formed therein adjacent its lower edge and providing a recess on its outerface, said recess having soft'solder applied therein at spaced points, 'wherebywhen' the collar is inserted in the container body andheat applied thereto said solder will form a bond betweenfth'e collar and the container for securing the collar therein.

' 3. 'Ancasy opening container having score linesinlthe body adjacentione end thereof forming a rip strip, a reclosure collar disposedwithin said container body, said 001- lar having an. inwardly projecting'fbead formed therein adjacent its lower edge and providing a recess on its outer face, said recess having soft solder applied therein, whereby I when the collaris inserted'in thecontainer V body-and heat/applied theretosaidsolder will form a bond between the collar and the Y container for securing the collar therein, said soft solder being of such ingredients that the V i solder 7 may be melted and the bond i formed Without injuring the lithographing on v the outer face of the container. 7 7
