MarCh 14, 1933. A. J. CHAMBERLAIN CLOSURE FOR CONTAINERS Filed sept. 5o, 1929 Patented Mar. 14, 1933 UNITED sTATEs .ALFRED J'. CHAMBERLAIN, OF MILWAUKEEpWISCONSIN CLSURE FOR CONTAINERS Application filed September 30, 1929. Serial No. 396,088.

This invention relates in general to closures for containersand more particularly to that type of closure which employs a gasket compressed between parts of the con- '.5 tainer and closure when the closure is applied whereby to provide a fluid tight seal.

One of the principal objects of the present invention is to provide a closure of this character wherein the gasket is organized in a novel manner with the closure so as to avoid the use of cement and the same time more positively secure the gasket in position.

In connection with closures of this type it has been proposed to secure the gasket to the flange of the cover or closure by cement,

but this has not been found satisfactory because the cement will discolor or otherwise impair the chemical products packaged in the container and also because the cement is dissolved or broken down by the contents of the container thus permitting the gasket to become loose and displaced or lost when the cover is removed.

With the present invention even after the closure has been removed from the container the gasket is positively held in proper position so that the container may be resealed without recementing the gasket or taking any other steps to secure the same in proper 3 position on the closure.

In general, the present invention greatly facilitates the application of the closure in liquid tight relation to the container and eliminates much labor, difficulty and annoyance heretofore incurred. Further, the present invention lessens the first cost of the container and closure.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawing forming a part of this specification, and in which:

Figure 1 isa fragmentary sectional view taken on line 1-1 of Figure 2;

Figure 2 is a fragmentary sectional view taken on line 2--2 of Figure 1, with parts broken away for the sake of illustration; and

Figure 3 is a fragmentary view in bottom plan showing another form of the invention.

Referring to the drawing, the numeral 1 designates generally the bod of a container which may be of any suitable construction and which is shown as having an outwardly p and downwardly inclined flange 2 around its upper open end, the fiange 2 providing a gasket seat. A closure designated at 3 is provided for the container and has a rim 4 60 formed with an outwardly and downwardly inclined flange 5. At spaced points about its circumference, the ange 5 has integrally formed therewith bendable sealing lugs 6. When the closure is applied to the container a gasket 7 is interposed between the

flanges

2 and 5 so that when the lugs 6 are bent up under the Harige 2 as clearly shown in Figure 1 the gasket 7 is compressed between the

flanges

5 and 2 tov afford a liquid tight seal.

The present invention proposes to secure the gasket 7 to the flange 5 and for this purpose, retaining lugs 8 are struck out of the metal of the flange 5 adjacent the sealing lugs 6, the lugs 8 being deflected or depressed in- 75 wardly and being imbedded in the gasket to secure the same in position. Any suitable number of lugs 8 are provided, but preferably there is a retaining lug 8 for each sealing or clinching lug 6. It is to be noted that, 8 even where the lugs 8 are struck out of the metal containing the clinching lugs 6 to the flange 5, the bending of lugs 6 does not affect the action of the retaining lugs or clips 8.

With this construction whenever the clo- 8 sure is applied to the container the gasket 7 is properly positioned for compression between the

flanges

5 and 2. The means employed for holding the gasket in position is not affected by the contents of the container and will not impair their quality or character in any respect. The application or removal of the closure from the container does not impair the function of the retaining lugs 8 and these lugs by holding the gasket 7 in position during removal protect the gasket so that resealing may be effected without giving the gasket any further attention'. It is to be noted that the lugs 6 have apertured hook-like extensions 6 to facilitate prying out of the lugs 6 and removal of the closure.

Referring to Fig. 3, the gasket retaining, lugs are designated at 8 and are in all respects similar to the retaining lugs 8 ot Figures l and 2 except that they are positioned in between the sealing lugs 8 and are formed as integral extensions of the Harige 5 instead of being struck from the metal connecting the sealing lugs 6 and Harige 5 as in the other A'embodiment of the invention. The lugs 8 operate in the same manner and have the sanie advantages as the lugs 8.

The invention claimed is:

1. rl`lie combination with a container having an outwardly extending surrounding Harige at its upper end, of a closure for the container having its marginal portion formed to provide a Harige to overlie the container Haiige and ext-end toward the outer edge thereof on applying the closure to the container, a gasket to be compressed between said Hanges, bendable lugs connected with the closure Harige and extending below the same to be bent under the container Hange for locking the closure to the container and compressingthe gasket between said Hanges, and gasket retainer clips connected with the closure Hange and extending into the space between said Hanges for connecting the gasket to the closure and for holding the gasket at kall times in position for compression between said Hanges on locking the closure to the container.

2. The combination with a container having an outwardly extending downwardly inclined surrounding Harige at its upper end, of a closure i'or the container having its marginal portion formed to provide a complimentary flange to overlie the container Harige and extend toward the outer edge thereof on applying the closure to the container, a gasket to be compressed between said Hanges, bendable lugs connected with the closure Hanges and extending below the same to be bent under the container Hange for locking the closure to the container and compressing the gasket between said Hanges, and gasket retainer clips pressed ont of the portion of the closure Harige above the lugs and extending into the space between said Hanges for connecting the gasket to the closure and for holding the gasket at all times in position for compression between said Hanges on locking the closure on the container.

3. The combination with a container having an outwardly extending surrounding Harige at its upper end, of a closure for the container having its marginal portion formed to provide a Hange to overlie the container Harige and extend toward the outer edge thereof on applying the closure to the container, a gasket to be compressed between said Hanges, spaced bendable lugs connected with the closure Harige and extending below the same to be bent under the container Harige for recitar locking the closure to the container and compressing the gasket between said Haiiges, and gasket retainer clips connected with the closure Harige between the lugs and extending into the space between said flanges for consure securing lugs carried by the closure and cooperable with the Harige oic the container to compress a sealing gasket between said Hanges, and a gasket for the closure, the combination with said gasket of gasket-securing lugs carried by the said closure and clamping said gasket firmly against the Hange of the closure, said gasket-securing lugs being. positioned above the circumferential line of bend of the closure-securing lugs as defined by the outer edge of the container Hange so as to extend into the space between the Hanges of the container and closure and overlie the Hange of the container when the closure is in place thereon, whereby the holding action ofL the gasket-securing lugs is unaffected by the bending of the closure-securing lu into and out of clamping' relation with the ange of the closure.

5. ln a container closure having an annular gasket-seating Harige cooperable with a similar Hange on a container, spaced bendable closure-securing lugs carried by the closure and cooperable with the Harige of the container to compress a sealing gasket between said Hanges, and a gasket for the closure, the combination with said gasket of gasket-securing lugs carried by the said closure and clamping said gasket firmly against the Harige oi the closure, said gasket-securing lugs being positioned between the closuresecuring lugs and above the circumferential line of bend of the closure-securing lugs as deiined by the outer edge of the container Hange so as to extend into the space between the Hanges of the container and closure and overlie the Harige oft-the container when the closure is in place thereon, whereby the holding action of the gasket-securing lugs is unaHected by the bending of the closure-securing lug into and out of clamping relation with the Harige of the closure.

6.y lin a container closure having an annular gasket-seating Hange cooperable with a similar Harige on a container, bendable closure-securing lugs carried by the closure and cooperable with the Hange of the container to compress a sealing gasket between said Hanges, and a gasket for the closure, the coinbination with said gasket of gasket-securing lugs carried by the said closure and clamping said gasket firmly against the Harige of the closure, said gasket-securing lugs being positioned in substantial axial ali ent with the closure securing lugs and a ove the circumferential line of bend of the closure-securing lugs as defined by the outer edge of the container flange so as to extend into the space between the flanges of the container and closure and overlie the flange of the container when the closure is in place thereon, whereby the holding action of the gasketsecuring lugs is unaffected by the bending of the closure-securing lug into and out of clamping relation with the ange of the closure.

In witness whereof, I hereto aix my signature.
