HOLDER FOB CGLLAPSIBLE TUBES.

Application le December 29, 1920. Serial No. $1,943.

This invention relates to a holder for collapsible tubes and is especially adapted to receive and permanently retain a tube of tooth paste or the like, it being the prime object to remove the ordinary screw cap from the tube and to securely hold the tube in the ncv'el collapsible tube holder by meansY of the screw threads on the neck of the tube.

Another object of this invention is to provide a novel collapsible tube holder having a backing plate adapted to lie next to the body of the tube, forming a substantially rigid plate against which the tube may be pressed to exhaust the contents from the tube. With my novel holder the entire contents of the tube may be completely expelled with very little trouble and without the need of folding over the empty sections of the tube, as is customary in the use of a tube of tooth paste.

A further object being to provide a collapsible tube holder with` an internal screw threaded portion for receiving the neck of the tube, and with a simple, easily operated shut-ofi' connection to be opened and closed before and after squeezing some of the contents from the tube. l provide a sanitary tube holder having comparatively few parts which may be readily disassembled and cleansed, when aiii'xing a new tube in place.

A still further objectof the invention is to provide a novel collapsible tube holder with an outlet adapted to convert any shape discharge of substance from the tube into a flat ribbon; it being best adapted to convert tooth paste into a ribbon, which is more easily applied to a tooth brush.

The above and other objects of my invention will more fully appear from the following description and drawing, and will be especially pointed out in the annexed claims.

F ig. l is a view in elevation of my novel collapsible tube holder having a tube in place, and showing one mode in which the holder may be hung up;

Fig. 1, a similar view, partially in section, it being broken away to show the manner in which the contents of the tube is expelled;

F 1g. 4, a cross sectional view taken on line 4`4, F ig. 1;

F ig. 5, shows a modified form of my novel collapsible tube holder.; and

F ig. 6 is a sectional view thereof, taken through the holder the tube being in. elevation.

In-Figs. 1%, l() denotes the body portion of my novel collapsible tube holder, which forms a backing plate for the collapsible tube 1l. rlhe body 10 may be of any desired coniiguration or design, but is preferably semi-circular at the portion intended to lie adjacent the tube, the upper portion 12 be- `ing of reduced size to provide a handle, in

which may be provided an aperture 13 to aid in hanging up the holder. The lower part of the holder, integral with the body portion, is formed into an annular cup shaped bottom 14, the inside surface 15 of which is tapered to conform with the bevel found on the top of the ordinary collapsible tube. As seen in Fig. 2, the head 16 of the tube rests on the taper in the bottom of the holder, which aids in expelling the last of the contents in the tube when it is pressed against the bottom of the holder. ln this embodiment the bottom 14 is provided with a central aperture 17 adapted to receive the screw threaded neck 18 of the tube, which projects outside the bottom and receives a retaining cap number 19. The internal screw threads 20 of the cap member communicate with a passage 21, through which the paste, or other contents of the tube is forced to the outside. The passage makes its outlet to one side ef the center of the bottom of the cap, which bottom is arc-shaped and has a shut-off member 22 reciprocating thereon. The shut-olf member may be held for reciprocation in any desired manner, and is shown herein being supplied with a spring wire 23 which passes through the member 22 and finds a pivot on each side of the cap. In the lower surface of the arc-shaped bottom is a groove 24, receiving a projection 25 on the shut-off member, which guides and limits the movement of the shut-otf member over the arc-shaped surface of the cap.

rIhe passage 21 in the cap is a narrow oblong one, this invention not being intended to be limited to that specific form, which is adapted to convert the substance squeezed therethrough into a at ribbon shaped strip,

the particular advantage beng to convert the round discharge of ordinary tubes of tooth paste into a ribbon, which is especially applicable to a tooth brush.

In using my novel collapsible tube holder it may be easily held and operated by one hand, or may be operated while in a position, like shown in Figs. 1 and 1, attached vertically on the side of a wall or cabinet, or it may be used while in a horizontal position on a table. I have provided a pair of lugs 26, formed on the outside of the body portion 10, which act as legs for supporting my novel holder and to prevent it from rolling,

The modification of this invention, illustrated in Figs. 5 and 6 of the drawing, comprises a handle 27 having a laterally offset cup shaped portion 28, annular in shape and adapted to receive the top portion of a collapsible tube, thebottom of said cup portion being tapered, similar to the taper 15 of the holder described above. The screw threaded neck 18 of the tube is, received in a centrally located aperture in the'bottom of the portion 28 and is retained in place in the cup by a cap 29.' Like the cap 19, the cap 29 has a passage 30 connecting vthe internally screw-threaded aperture with the outside surface, preferably the bottom, the lower portion of the capI being of reduced diameter and having an annular groove 31. 32 denotes a revoluble cap thereon. The revoluble cap is provided with an eccentrically arranged opening 34 designed to register with the passage 30 when in one position, and to be moved away from the passage by a simple rotation of the revoluble cap.

In operation this novel collapsible tube holder is simple, rapid and easy to attach to an ordinary collapsible tube. The screw threaded cap of the tube is first removed and the tube is placed in position in the holder, the neck 18 projecting through the aperture in the bottom thereof. My improved cap 19 is then screwed o n the neck of the tube, which serves to securely fix the tube in place in the holder, and the device is then ready for use.'

The advantages of th is invention will obviously become apparent from an understanding of the foregoing detailed description. My novel collapsible tube holder eliminates the necessity of removing and replacing the ordinary cap each time an amount of the contents of the tube is needed, which operation requires the use of two hands. Tith my improved holder it is easily possibleto exhaust the entire contents of the tube and to conveniently operate it with 'only one hand.

support; a

It is to 'be understood that the construction disclosed herein is illustrative but not restrictive and that the same may be modified within the meaning and scope of the following claims.
