DISPENSING CONTAINER FOR POWDERED MATERIALS Filed Aug. 22, 1952 INVENTOR Bruce 13. Gordon 2 BY MM, @fi EwJXAaw l ATTORNEY United States Patent DISPENSING CONTAINER FOR POWDERED MATERIALS Bruce B. Gordon, Glen Rock, N. J., assignor to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application August 22, 1952, Serial No. 305,767

1 Claim. (Cl. 222-542) The invention relates to a new and useful improvement in a dispensing container for powdered materials. It is a common practice to attach a closure end having a breast and a perforated nozzle to the body portion of a metal container by providing the breast with a depending skirt which makes frictional contact with the upper end of the container body. It is also a common practice to place in the breast a sealing gasket which makes sealing engagement with the upper end of the body wall of the container when the closure is assembled on the body. The gasket is usually held in the breast merely by frictional contact with the skirt of the breast. The gasket often becomes dislodged from its frictional grip with the breast and when the breast is assembled on the body without the sealing gasket there is an objectionable leakage of the powdered material when the container is inverted for dispensing the powder.

An object of the present invention is to provide the skirt of the breast with a positive means underlying the gasket for retaining the gasket as a unit in the breast before assembly, which means is so disposed that it does not interfere with the attachment of the breast to the body of the container and the sealing of the container.

In the drawings, which show one embodiment of the invention: 1

Figure l is a side view of the container with parts broken away to show the sealing gasket and the means for retaining the same in the breast;

Figure 2 is a view in perspective showing the closure member, the sealing gasket and the upper end portion of the container with the parts separated from each other; and

Figure 3 is an enlarged view of a portion of the upper end of the container, said view being partly in vertical section and partly in side elevation.

The improved powder dispensing container includes a metal body having fiat sides and rounded corners. It also includes a perforated closure end formed with a breast and a nozzle section which are joined by an interfolded seam. The breast has a skirt at its peripheral edge which is shaped so as to have flat portions and rounded corners conforming to the shape of the body and dimensioned so that the skirt portion makes frictional contact with the outer upper portion of the body wall. Within the breast is a sealing gasket having a central opening and with its peripheral edge shaped so as to have flat portions and rounded corners conforming to the shape of the skirt and dimensioned so as to frictionally engage said skirt. The skirt of the breast is provided with dimples which underlie the sealing gasket and retains the sealing gasket as a unit in the breast before the breast is assembled on the container body. The upper edge portion of the body wall is tapered inwardly so as to make sealing engagement with the gasket back from the edge and provide a space for these holding dimples formed in the skirt of the breast.

Referring more in detail to the drawings, the improved dispensing container consists of a body wall 1 having fiat sides 2 and rounded corners 3. The body wall is beaded all the way around the upper end as indicated at 4. This bead is spaced some distance below the upper end of the walls of the container. Above the beaded portion the wall is straight as indicated at 5. This provides a frictional seat for the closure member. The closiii) 2,695,738 Patented Nov. 30, 1954 ure member includes a breast 6 to which a nozzle 7 is secured by an interfolded seam 8. This breast is generally curved upwardly but all the way around the peripheral portion of the breast is a horizontal or fiat portion 9. Depending from the outer edge of this flat portion 9 is a skirt 10 which has flat sides and rounded corners to conform to the body wall of the container and this skirt is dimensioned so as to make tight frictl0illal engagement with the friction seat 5 on the body wa The nozzle 7 has the usual end closure 11 which is perforated and a cap 12 having a closed end 13 which is likewise perforated is rotatably mounted on the nozzle. This nozzle and the rotatable cap are of the usual construction and further description thereof is not thought necessary.

Within the breast is a sealing gasket 14. The sealing gasket has fiat sides 15 and rounded corners 16 conforming to the shape of the inner surface of the skirt 10 and dimensioned so as to engage the inner :face of the flat portion 9 of the breast. Preferably the gasket is dimensioned so as to contact with the skirt. In order to hold the gasket in the breast before the parts are assembled the skirt is provided with dimples 17. As shown there are two dimples in each side wall of the skirt. The number of dimples, however, may be varied. These dimples retain the gasket 14 in the breast. The body wall all the way around is tapered inwardly from a point just above the friction seat 5 to the end of the wall as indicated at 18. This causes the upper end of the body wall to engage the sealing gasket inwardly from the peripheral edge thereof as indicated at 19. This provides a space between the tapered portion of the body wall and the depending skirt for the dimples 17 when the closure is assembled on the container. In view of this space for the dimples, said dimples do not in any way interfere with the forcing of the skirt of the breast downwardly into frictional engagement with the seat 5 in the body wall until a tight sealing contact between the end of the body wall and the gasket is obtained.

The gasket is preferably of paper and has a center opening 20 through which the powder passes into the nozzle when the container is inverted for dispensing powder. This gasket does not have to be made so as to accurately engage the depending skirt. for the reason that the dimples 17 serve as a positive means for retaining the gasket in the breast before the breast is assembled on the container.

It is obvious that minor changes may be made in the means for holding the sealing gasket in assembled position within the breast Without departing from the spirit of the invention as set forth in the appended claim.

I claim:

A container for dispensing powdered material comprising a metal body having flat side walls and rounded corners, a closure for said body including a breast having a depending skirt adapted to make frictional contact with the outer face of the body walls, said breast having a neck section joined thereto with dispensing perforations in the closed end thereof, a cap rotatably connected to said neck section for controlling said dispensing perforations, an annular sealing gasket disposed in and seating against the underside of the peripheral portion of said breast when the closure is assembled on said body, and inwardly extending dimples formed in said skirt below the gasket for retaining said gasket in said breast as a unit before assembly, the upper portion of said body wall being tapered inwardly and spaced away from said skirt and adapted to make sealing engagement with said gasket, said dimples being disposed in said space between the tapered portion of the body wall and the skirt when the breast is in assembled position.
