Application April 17, 1952, Serial No. 282,785

Glaims.

This invention relates to an improvement in a dispensing device. More specifically this invention relates to a collapsible tube having an improved holder by which the tube may be held during the collapsing and dispensing operation.

It is a prime object therefore to provide an improved holder for a collapsible tube, the holder comprising a relatively flat and thin base to which the tube is releasably connected.

Another object is to provide an improved collapsible tube holder which is held in assembly with the tube by means of a pressure sensitive adhesive, the tube including a turnable key whereby the tube may be collapsed and the portion thereof which is rolled upon the turning of the key is released from the holder.

A still more specific object is to provide an improved collapsible tube dispenser having a base member releasably connected thereto, the tube including a, key which is integral with the tube for collapsing the tube and for releasing the tube from the holder.

A still further object is to provide an improved collapsible tube holder which is held in assembly integrally with the collapsible tube, the tube including means for collapsing the same and for simultaneously breaking the collapsed portion of the tube free of the holder.

These and further objects will become more readily apparent from a reading of the specification when examined in connection with the accompanying sheet of drawing.

In the drawing:

Figure l is a side elevational view of a collapsible tube and holder therefor;

Figure 2 is a plan view of the tube and holder shown in Figure 1;

Figure 3 is a plan view of a modified collapsible tube dispenser and holder therefor;

Figure 4 is a sectional View taken along the line 3-4 of Figure 3; and

Figure 5 is a sectional view taken along the line 5-5 of Figure 2.

Referring now to Figures 1, 2 and 5, a dispenser is generally designated by the reference character It. This dispenser ill comprises a flat base or holder l i, this holder being made of any suitable relatively stii'i material for supporting a collapsible tube iii. The collapsible tube i2 comprises a reduced section or neck it to which a conventional cover or neck it is connected.

The lower edge or surface E5 of the tube i2 is fastened to the base I l by means of an adhesive Hi. The adhesive i6 firmly connects the tube 52 and base i l in assembly, and the adhesive it may be of the pressure releasable type or it may consist of any satisfactory compound that will provide strong but releasable adherence.

One end of the tube i2 is provided with a. thin flat section ll which is integrally formed with a key l8 having a stem l8 extending laterally across the flat section ll. The tube [2 and the key l8 may be of integral cast or plastic material of a type particularly effective in a collapsible tube construction.

During use the key 68 is turned and the tube l2 collapsed and rolled as indicated at 2B in Figure 1 whereupon the material Within the tube is ejected through the neck I3. During this use the operator firmly grips laterally spaced edges of the base l l which project laterally outwardly with respect to the tube [2. In this manner he can firmly grip the tube l2 and hold the same while the key is is turned for collapsing the tube. The collapsed portion of the tube 12 as indicated at 28 is broken or released free of the base H.

The modified dispenser shown in Figures 3 and 4 is similar to the one above described, including however a base 2! which is integral with the tube This type of construction can adequately be made by a well-known molded plastic operation. When the key 18 is turned here the relatively thin section 22 which holds the tube l2 to the base 2! is broken free as indicated at 23 in Figure 3.

Thus an improved collapsible tube dispenser and a modification thereof has been described. This type of dispenser is particularly Well adapted for dispensing semi-fluid materials such as toothpaste, paint pigments, chemicals, medicines, etc. The holder is effective to firmly support the tube while it is being collapsed. An ancillary use of the base may be for descriptive matter, advertising, etc.

Thus the objects of the invention have been fully achieved and it must be understood that changes may be made in the construction Without departing from the spirit of the invention as disclosed nor the scope thereof as defined in the appended claims:

What is claimed is:

1. In a dispensing device, a substantially flat holder, a collapsible tube positioned on said holder, said tube comprising a longitudinally extending body having at one end a reduced neck portion and a closure member for said neck portion, a relatively flat portion on the opposite end of said tube, a turnable key connected to said flat end portion, and an adhesive substantially coextensive on one side of said body of said tube,

said adhesive adhering to the flat portion of said holder for releasably securing said tube and holder in contiguous and parallel assembly, the key being turnable for collapsing and rolling said tube whereby the rolled portion of the tube is released from adherence with the holder.

2. In a dispensing device in accordance with claim 1, wherein the key is an integral part of the fiat portion of the collapsible tube.

3. In a dispensing device in accordance with claim 1, wherein the key includes a stem extending laterally of the flat portion and being integral therewith.

4. In a dispensing device, a holder comprising a flat base, a collapsible tube on said base, said collapsible tube including a longitudinal body having a substantially fiat portion at one end, a key connected to said flat portion, and an adhesive substantially coextensive with one side of said body and adhering to said body and said fiat base for connecting said tube and said base in contiguous and parallel relation, said key being turnable for collapsing and rolling said tube whereby the rolled portion breaks free of the adhesive connection with respect to said base.

said base.
