7 2,684,791 GOLLAPSIBLE DISPENSING CONTAINER Harry Sebell, Wolfeboro Falls, N. H., assignor to Reynolds Metals Com corporation of Delaware Application January 18, 1951, Serial No. 206,634

2 Claims. 1,

This invention relates to collapsible dispensing containers which may be used for dispensing material in paste form, tooth paste and shaving cream being, familiar examples of such material. One object of the invention is to provide a novel container which has. a discharge opening at its front end and a movable rear end member at the other end, against which pressure may be applied to force some of the contents through the discharge opening.

In the drawings,

Fig. 1 is a sectional view of a container embodying the invention.

Fig. 2 is a sectional view showing the rear end member.

Fig. 3 is a sectional view of the container body.

Fig. 4 is a sectional view illustrating a rear cover element which is applied to the rear end of the container.

Fig. 5 is an enlarged fragmentary sectional view illustrating the manner in which the end member and the body member are united.

Fig. 6 is a sectional view showing the position of the end member when the container is substantially empty.

Fig. 7 is an enlarged section on the line 1-1 Fig. 2.

The container herein shown includes a body member indicated generally at I which is formed with a side wall portion 2 and a front end portion 3, the latter preferably being relatively inflexible. The end portion 3 is shown as having a discharge opening 4 which is surrounded by an exteriorly screw threaded neck 5 adapted to receive a removable closure 6.

The rear end member is indicated generally at "l and it comprises a relatively inflexible body section 8 which is of a size to fit within the walls 2 of the container body I, and an extensible skirt section 5 which may be made of any thin soft easily foldable material, preferably metal, said skirt section having at its upper edge an outwardly extending seaming flange Ill.

The skirt section 9 is permanently united to the open end 25 of the container body I, and this may be accomplished in any approved way, as for instance by rolling together the seaming flange it of the end member and a seaming flange l i with which the container body is provided, thereb forming the lock seam l2.

With this construction the rear end member 1 closes the rear open end 25 of the container body I and a tight joint is provided where the edges I0 and II of the rear end member and the container body are connected together.

pany, Richmond, Va., a

As stated above, the skirt section 9 of the end member is extensible so that by applying pressure to the rear face of the body section 8 after the closure cap 6 has been removed said body section may be moved forwardly in the container body thereby forcing some of the material 20 within the container outwardly through the discharge opening 4.

The end member 1 may be made of any suitable soft ductile metal, such as aluminum, which can be fashioned to present a body section 8 having a proper thickness and stiffness to withstand the pressure applied thereto necessary to force. the contents 2!) of the container through the discharge opening 4, and also to present the skirt section 9 which can be readily extended. In forming the end member the skirt section is preferably reduced to a thickness on the order of foil, thereby providing a skirt section which can be easily shortened by forming circumferential folds 13 therein and can be extended by applying pressure to the relatively stiff body section 8.

The device also preferably embodies a rear cover member M which, desirably, is made of sheet metal, such as tin plate, that is somewhat stiffer and less ductile than that used in making the end member 1.

This cover member is initially formed with a seaming flange [5 that is rolled into the lock seam [2 along with the seaming flanges l0 and I l, thereby forming what might be called a triple lock seam.

Said cover member is provided with a central opening it and the material of the cover immediately surrounding said opening is curled upwardly and backwardly to form a bead IT. The opening it provides access to the body section 8 so that a person using the container for dispensing its contents can insert his thumb or finger through the opening [6 for the purpose of applying the necessary pressure to said body section 8.

The container body may be made of any desirable material but is preferably made of metal and the side wall 2 thereof can be relatively thin metal. It is desirable, however, that the front end portion 3 should be relatively inflexible so that when the contents of the container are to be dispensed the front end 3 of the container body may be placed against ones fingers while the thumb is entered into the opening it to apply the necessary pressure to the body 8 of the end member.

In order to provide for dispensing all of the 3 contents of the container, including that within the neck 5, the body section B of the end member may be provided with a cylindrical extension 2| of a size to fit the discharge opening 4, which extension has a plurality of exterior grooves 22.

After the body section 8 has been moved forwardly into a position in which the extension enters the discharge opening 4, as shown in Fig. 6, then during further forward movement, the material between said body section and the front wall 3 of the container body will be discharged through the grooves 22 and said extension will force all the material within the neck 5 out through the discharge opening.

I claim:

1. A dispensing container comprising a container body having at its front end a neck providing a discharge opening, a removable closure secured to said neck, and an end member having a relatively inflexible body section of a size to fit within the container body and also having a rearwardly directed extensible skirt section, the edge of the skirt section and the edge of the container body being rolled together to form a lock seam, said body section having a forwardly directed extension of a size to fit the discharge opening through said neck, which extension has exterior discharge grooves, whereby during the final forward movement of the body section of the end member the entire contents of the container, including that which is located in the neck, will be discharged by said extension and through the grooves therein.

2. A dispensing container comprising a container body having at its front end a neck providing a discharge opening, closure means associated with said neck, and an end member having a relatively inflexible body section of a size to fit within the container body and also having a rearwardly directed extensible skirt section, the edge of the skirt section and the edge of the container body being rolled together to form a lock seam, said body section having a forwardly directed extension of a size to fit the discharge opening through said neck, which extension has. exterior discharge grooves, whereby during the final forward movement of the body section of the end member the entire contents of the container, including that which is located in the neck, will be discharged by said extension and through the grooves therein.
