May 22, 1 34- J. M. HOTHERSALL CONTAINER Filed NOV. 2, 1932 INVENTOR ATTORN EY Patented May 22, 1934 UNITED STATES 1,959,36} CONTAINER John M. Hothersall, Brooklyn, N. Y., assignor to American Can Company, New York, N. Y., a corporation of New Jersey Application November 2, 1932, Serial No. 640,801

a Claims. (01. 221-62) The present invention relates in generalto containers adapted for the packaging of spices or like materials, and has for a particular object the provision of the sealing of a dispensing opening 5 o'r aperture formed in the container top, with a frangible seal, together with a sliding closure for subsequently opening and closing the aperture embodied comprises a body 11 having a. bottom 12 after the frangible seal has been broken.

A frangible seal provides against any leakage 1 )f the materialin the can during shipment and during all of the rough handling incident thereto even though this material be finely pulverized. Where only a sliding closure is used during the shipment there is always the possibility that the slide may become displaced. Furthermore, maintaining a uniformly tight fitting slide construction for all cans presents a manufacturing problem which -requires extreme diligence with its attendant expense to provide satisfactory cans. In the slide go construction of the can embodying the present invention the slide fit need not be so accurate since the package before breaking of the frangible seal is absolutely tight and sift proof.

The principal object of the invention is the provision of a container of the character specified wherein the contents. are sealed by means of an inside frangible seal which forms a tight closure until the contents are to be dispensed, at which time the frangible seal is broken, when there then remains a sliding closure for a dispensing aperture.

An important object of the invention is the provision of a container of the character described having the combination of a frangible seal for sealing the contents prior to opening of the container and an improved spring-held form of sliding closure for subsequently opening and closing the container to permit dispensing of its contents.

A further important object of the invention is the provision of a container body seamed to an apertured top and a frangible seal incorporated in the seamed joint and closing the aperture, the seamedjoint surrounding a depression in the top part of the container in which a sliding closure is located.

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 drawing,

discloses a preferred embodiment thereof.

Referring to the drawing:

Fig. 1 is a perspective view of a container em-' bodying the present invention, this view illus I trating the container fully closed; I

Fig. 2 is a view similar to Fig. 1 illustrating the sliding closure member withdrawn from closing position; and

Fig. 3 is an enlarged longitudinal sectional view taken through the container and illustrating the construction of parts.

The container in which the present invention is and a top 13. The peripheral edges of the body are flanged at 14 and 15 and are included in a 5' bottom seam 16 uniting the body and the bottom and in a top seam 1'7 uniting the body and the top. The top is apertured at 21 and its peripheral edges are included in the seam 1'7. These edges in cross section are formed in the shape of a 7 letter U having legs 22, 23, the latter joining with a downwardly extending wall 24 connected with the central part of the top '13.

A frangible seal 25, which may be of. fibre, foil or other suitable material, is located beneath the top 13 and its peripheral edges 26 are included in the seam 17, the legs 22, 23 holding tightly against the flange 15 of the body 11 and the flange 26 of the frangible seal. In forming both of the seams 16 and 1'7, the interengaged parts are preferably first connected together while the. II flanges 14, 15 are straight, i. e., in the plane of the body wall, and are then preferably bent inwardly as shown in Fig. 3. In this bending to assembled position the frangible seal is stretched tightly over the bend which joins the parts 23, 24 of the top 13, this bend being designated by the numeral I 2'7.

The frangible seal 25 confines the contents of the container during shipment to the ultimate consumer and it is only after the seal has been broken that access to the contents of the container is had.

A supplemental sliding closure 31 is provided for protecting that partof the frangible seal 25 which is accessible through the aperture 21 of the top and this closure part also provides a shutter member for cooperation with the aperture in dispensing the contents of the container after the seal has been broken. I

The closure 31 is provided with parallel side edges 32 which are guided in a straight line of travel as the closure is slid from opening to closing position or vice versa.. These edges are confined between retaining lugs 33 which are stuck out from the top 13 and are bent over the upper face of the sliding closure 31. I

The closure 31 is alsoprovidedwith stop projections 34 which strike against the retaining lugs 33 and limit the sliding movement of the closure ends of the slide 31 and these provide curled finger holds for moving the slide into aperture closing position or into open position. The two forward lugs 34' are slightly bent downward as at 36 (Fig. 3) and these'bent ends resting against the top. surface of the part 13 put a spring holding action on the slide which prevents any inadvertent movement. When the slide is in closed position, 'these bent lugs engage over the inclined wall 24, of the top 13 and frictionally hold the slide in closed position.

When the slide is moved into 'the position shown in Fig. 2 the aperture 21 is exposed and the frangible seal 25 directly under the aperture may then be broken by any suitable sharp instrument which when applied from above easily tears the frangible seal. This conditions the container for dispensing and its contents may then be discharged through the aperture 21 after which the slide 31 may. be moved into the position illustrated in Fig. 1, at which time the container is fully .closed and the contents prevented from sifting. i

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.

I'claim:

1. A container, comprising a body, a one-piece top seamed to said body and having an aperture, 9. frangible seal for sealing the contents in said container, said seal having its margin incorporated within the top seam and thereby secured to said top and closing said aperture, and a sliding closure mounted in said top for opening and closing said aperture after said frangible seal has been broken.

2. A container, comprising a body, a one-piece top seamed to said body and having an aperture, a frangible seal located beneath said top for sealing the contents in said container, said seal having its margin incorporated within the top seam and thereby secured to said top and said body in their seamed joint and closing said aperture, and a sliding closure mounted in and above said top for opening and closing said aperture after said frangible seal has been broken.

3. A container, comprising a body, a one-piece top seamed to .said body and having an aperture, a frangible seal for sealing the contents in said container, said seal having its margin incorporated within'the top seam and thereby secured to said top and closing said aperture, an imperforate sliding closure mounted in said top for opening and closing said aperture after said frangible seal has been broken, said top being formed with integral retaining lugs for engaging and guiding said sliding closure. v
