1t tjlaim. (Ci. 222-4542) The invention relates to new and useful improvements in a dispensing container for powdered materials.

One of the common forms of containers for dispensing powdered materials includes a body portion having fiat sides and rounded corners. The closure member for the body includes a breast having a depending skirt which frictionally engages the upper outer portion of the body wall. Within the skirted portion of the breast is a gasket which is clamped between a shoulder portion of the breast and the top edge of the body wall when the closure is applied to the container body. This gasket is usually of paper and in the commercial form of container referred to is held in the skirted breast by frictional engagement with the skirt. The gasket is inserted in the closure member. When the frictional contact of the gasket with the skirted breast is the sole means for holding the gasket attached to the closure member the gasket often falls out during the handling of the closure member and the assembling of the same on the body.

An object of the present invention is to provide a re tainer which is frictionally attached to the neck portion of the closure member and is provided with a flange which projects outwardly and beneath the gasket for holding the gasket in the skirted breast when the closure member is unattached to the container body.

A further object of the invention is to provide a retainer for the gasket with an upturned portion which is closely associated with the flat sides of the container body midway between the ends thereof so as to prevent said body wall from springing away from the skirt of the breast with a resulting leakage of powder.

In the drawings:

Figure 1 is a view partly in side elevation and partly in vertical section through the upper portion of a container embodying the improvements.

Figure 2 is a view through a portion of the container on the line 22 of Figure 1, the upper end portion of the retainer being shown in this view.

Figure 3 is a view partly in section and partly in side elevation of the gasket retainer, and

Figure 4 is a top plan view of the same.

The dispensing container to which the improvements have been applied includes a body portion 1, preferably having flat sides 2 and rounded corners 3. The body wall is beaded at 4 all the way around to strengthen the same and prevent the fiat sides from springing inwardly or outwardly. The upper portion 5 of the body wall is offset inwardly for reasons which will be pointed out later. The closure member for the powder container includes a breast portion 6 having a depending skirt 7 with flat sides and rounded corners conforming to the shaping of the body of the container and dimensioned so that the lower portions of the skirt will make tight frictional contact with the body wall in the region beneath the inwardly offset portion 5. Attached to this breast 6 is a neck portion 8. This neck portion as shown is made from a separate piece of metal and joined to the breast by a lock seam indicated at 9. The neck portion has a closed end 10 provided with perforations 11. Rotatably mounted on this neck portion is a cap 12 having perforations 13 which may be moved into and out of alignment with the perforations 11 in the end of the neck portion of the closure. Disposed in the skirted portion of the breast is a gasket 14 preferably of paper. The gasket is shaped so that the outer edges thereof have flat portions and rounded corners which are adapted to engage the skirt 7, said gasket also has an opening 15 therethrough. When the closure is attached to the body portion the gasket 14 is pressed by the shoulder 16 in the breast against the upper edge 17 of the body wall. The upper portion of the body wall is oifset inwardly as indicated at 5 so that this upper edge of the body wall will engage the gasket inwardly from the outer edge 18 of the gasket. it has been a common practice to depend upon the thin paper gasket making frictional contact with the skirt for retaining the gasket in the skirted breast. This often fails and allows the gasket to fall out of the closure member during the handling of the same preparatory to the assembling of the closure member on the container body.

In order to insure that the gasket will be retained within the skirted breast applicant has provided a retainer 19. This retainer includes a cylindrical body, the upper portion 2'1 of which makes tight frictional contact with the inner surface of the neck 3. The retainer has a laterally projecting flange 21 at the lower end thereof, which flange is turned upwardly so that the upper I end portion 22 thereof will lie beneath thegasket l4 and this will prevent the gasket from dropping out of the container. The upstanding end 22 of the retainer is circular but the gasket is of sufficient width so that the end portion of the retainer all the way around is well beneath the gasket and can serve to retain the gasket in proper contact with the skirt so that when the closure member is forced onto the container the gasket will be firmly clamped between the shoulder 36 and the edge 17 of the body wall.

it will be noted from Figure 2 that the upstanding edge portion 22 of the retainer 19 lies very close to the in- Wardly offset portion 5' of the body wall midway between the ends of the hat sections. This provides a means for preventing the body wall from springing inwardly away from the skirt '7 so as to disturb the sealing contact with the gasket and resulting in a leakage of the powdered material. The retainer, therefore, not only functions to retain the gasket in the skirted breast of the closure but it also serves to prevent inward springing of the flat side walls of the body thus providing an avenue of escape for the powdered material. The upper end of the retainer is curved as indicated at 23 and is provided with an opening 24 through its end permitting the free passage of the powdered material to the upper end portion of the neck of the closure member. This curving of the upper end of the retainer strengthens the wall of the retainer against flexing inwardly and aids in holding the upper portion 20 f the retainer in tight frictional engagement with the inner surface of the neck portion 8.

it is obvious that minor changes in details of construction and arrangement of parts may be made without departing from the spirit of the invention as set forth in the appended claim.

I claim:

A container for dispensing powdered materials comprising a body having fiat sides and rounded corners, a breast having a depending skirt shaped and dimensioned so as to make frictional contact with the outer face of said body, a dispensing neck portion carried by said breast and a rotatable closure member attached to said neck, said neck portion having an inner cylindrical surface, a gasket disposed in said breast adapted to make sealing contact with the end of the body wall when the breast and associated parts are assembled on said body, and a gasket retaining sleeve having an outer cylindrical surface dimensioned so as to make tight frictional engagement with the cylindrical surface on the neck and having a laterally extending portion disposed within said breast beneath the gasket for retaining the gasket in the breast when it is detached from the body of the container.
