2,030,696 DISPENSING CONTAINER John S. Forster, Pittsburgh, Pa., assignor of onehalf to Raymond Schmidt, Pittsburgh, Pa.

Application February 25, .1935, Serial No. 1,969

3 Claims. (Cl. 221-60) of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference may be had to the following detailed description, taken in connection .with the accompanying drawing, in 20 whichn Figure 1 is a view, partly in section and partly in side elevation, showing a-dispensing container constructed in accordance with my invention. with the parts in unassembled arrangement,

' Fig. 2 is a view, partly in section and partly in side elevation of the upper end of a dispensing container showing the structure after it has been assembled, V

Fig. 3 is a view similar to Fig. 2, showing the closure member in a different position, with the opening therein in alinement with the opening in the top of the container,

Fig. 4 is a view, partly in section and part in side elevation of the upper end of a dispensing container showing a modification of the closure member,

Fig. 5 is a view in section showing the upper part of a dispensing container similar to that illustrated in Fig. 4,- but with the closure member 40 disposed in its open position, and

Fig. 6 is a view in vertical section of a closure member similar to that shown in Figs. 2 and 3,

illustrating a different method of connecting the neck to the top of the container.

Referring now to the drawing, and Figs. 1 to 3 in particular, the dispensing container comprises a tube'lll carrying a top H which is provided with a neck l2. In constructing a container of this kind, it is preferable to use a metal such as tin or aluminum which may be readily extruded. While these metals are suitable, and have been widely used for constructing such dispensing containers, when it-is desired to use the container 55 for materials which will react with these metals,

any other suitable material such as alloys or other metals may be substituted.

The common practice in constructing collapsible containers from tin or aluminum is to extrude them. The container such as I have introduced lends itself very readily to extruding. In extruding these tubes, they are made with the lower end of the tube Ill open. This open end of the tube may be closed by collapsing the lower end of the tube to provide meeting edges and then crimping it in a manner well known in the art, and so it has been deemed unnecessary to illustrate the crimped end.

As illustrated in Figs. 1 to 5, inclusive, the top H and neck I2 aremade integral. A seat 13 is provided between the top H and neck l2. The size of the seat l3 will depend on the size of the closure member it is desired to use and which will be described hereinafter. As illustrated, the

seat is substantially conical in shape or'it may be said that it simulates the surface of a conic frustum. An opening I4 is provided in the top H through which materials stored in the tube may be extruded. Generally the opening is disposed centrally of the neck I? and tube I ll.

A notch I5 is provided in the neck I! to receive the'actuating member provided for operillustrated, the closure member is made of such a size that it will just snugly fit within the neck 12.

It is preferably made from the same metal as the tube l0.

An opening I8 is provided in the closure member l1. While in this embodiment the opening I8 is illustrated as circular in cross-section, other shapes may be employed. The size of the opening l8 will depend upon the material that is to be dispensed from the container and other conditions that are generally taken into account when designing such tubes. The edges defining the opening !8 are slightly flattened or rounded so that they will not cut the'washer l6.

In the modification illustrated in Figs. 1 to 3, inclusive, an eye member I9 is provided on the closure member IT. This eye member is disposed at right angles tov the axis of the opening it through the-closure member and midway between the ends of the opening. This eye mem-' ber has a double function. It may be employed for actuating the closure member to aline the opening I 8 with the opening ll in the top H, or it may be used for'hanging the dispensing container on a hook or other support when not in use.

In assembling the dispensing container, the closure member I! is pressed downwardly into the neck forcing the washer I 6 into tight engagement with the seat B. The wall of the neck I! is then bent inwardly, engaging the closure member to holdit in position.

It may be desirable in assembling the dispensing container to press the closure member into the cork washer to give more than a line contact. By pressing the closure member downwardly, it is caused to engage the washer over an area simulating a hollow circle, thus producing a good tight closure.

' Assuming the closure member stands in the position illustrated in Fig. 2, and it is desired to set the closure member to permit the extrusion of the contents of the tube, then the eye member I9 is rotated through a ninety degree angle to the position illustrated in full lines in Fig. 3. The opening i8 in e closure member is then aiined with theopening l4 in the top H and the contents may be extruded in the usual manner by collapsing a portion of the tube.

when it is desired to close the tube, the eye member I9 is merely rotated to the vertical position again and then rotated about the vertical axis carrying the opening [8 to a point out of alinement with .the notch l5. When the tube has been closed in this manner, it cannot again be opened until the closure member I1 is rotated about two axes. Therefore a very dependable the neck It.

In the structure illustrated in Fig. 4, the closure member is opened by swinging the ring 20 to the position illustrated in Fig. 5. In this manner the opening l8 in the closure member is alined with the opening I l in the top H. To close the tube the ring 20 is merely swung into the vertical position' again.

In the modifications shown in Figs. 1 to 5, inclusive, the closure member is formed integral with the tube Ill. In the modification illustrated in Fig. 6, a slightly different construction is employed. As illustrated, the neck I! is made longer," presenting a hollow cylindrical portion below the member may'be used with a number of tubes.

Since certain changes may be made in the above invention and different embodiments of the invention made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limitingsense.

It is also to be understood that the following claims are intended to cover all of the generic lating a surface of a conic frustum inverted, a

cork washer disposed in the neck, a substantially spherical closure member having a discharge.

opening extending therethrough. disposed in the neck, the closure member pressing the washer tightly against the seat, means for retaining the closure member in engagement with the cork washer, an eye member carried by the closure member providing means for operating it, the eye member being disposed at right angles to the opening through the closure member and midway between the ends of the opening, the neck having a U-shaped notch therein to permit the operation of the eye member tcr'rotate the 010- sure member to setthe opening therethrough in alinement with the opening in the top.

, 2. In a dispensing container in combination, a hollow cylindrical neckportion, a seat in the lower end of the neck portion, the seat simulating the surface of a conic frustum. inverted, a cork washer mounted on the seat and a substantially spherical closure member having an an opening therethrough disposed in the hollow cylindrical neck engaging the washer throughout the area of an annulus located within the boundaries of the washer and pressing it into tight engagement with the seat thus providing a good closure, means for actuating the closure member to aline the opening therein with the axis of the neck, and means for connecting the neck portion to a. container.

3. In a dispensing container in combination,

a hollow cylindrical neck portion, a seat in the bottom of the neck portion, the seat simulating the surface of an inverted conic frustum, a cork washer disposed in the neck above the seat, a substantially spherical closure member having an opening therethrough disposed in the hollow cylindrical neck engaging thewasher throughout the area of an annulus lying within the boundaries of said washer and pressing it tightly into engagement with the seat thus providing a good closure, the wall of the outer end of the neck extending inwardly engaging the closure member to retain it in position, an eye member carried by the closure, member, the eye member being disposed at right angles to the axis of the opening through the closure member and substantially equally spaced from the ends of said opening, the neck portion having a notch cut in its well to permit a movement of the eye member to a predetermined position to open the tube, and means for connecting the neck to a container.
