' The main object of the invention is to provide a dispensing device which is simple in construction, eflicient in operation and rel 'atively easy to assemble;

Another. 'object of the invention is to provide a dispensing closure for collapsible tubes "and the like which "has theabove desirable characteristics and one which is also an efficient closure which is desirableparticularly where the tube contains material affected by air. V

H Objects relating to' details and economies ojf'my invention willv appear fromthe description to follow. The invention is defined and pointed out in the claims. p v

A structure'which is a preferred embodiment of my invention is illustrated in the ac- 'companying drawings, in which T Fig.1 is a plan View partially broken away of a collapsible tube constructed in accordance with my invention. 1

Fig. 2 is a'fragmentary view in vertical section of the tube taken on line 2-2 of Fig.3.. y

Fig. 3 is a horizontal sectional 'view of the tube taken onjline 3-3 of Figs. 1 and 2.

Fig. 4 is a view similar to F ig, '3 showing the cap in a'closed position. 1

Fig. 5 is a bottom 'plan' alone, and v Fig.6 is a top plan view ofthe neck of thetube without thecap.

"In the drawings, numeral- 1 -indicates- .a collapsible tube, the contents of which may be tooth paste, shaving cream, paint pigment or the like. The tube 1 is provided witha view or the cap neck 2 of reduced section which is prefers ably in the'form of a cylinder. 7 4 At the bottom of the neck 2 :is formed a horizontal partition 3 having a vertical stud 4 concentric with the cylindrical neck2 and surmounted by a spindle 5 havinga late'ralr tentsthereof are 'forced through the opening lyprojecting head 6. A vertical'slotf7 extends through the partition3 whereby contents of the tube 1 may 'be'squeezed into the neck 2. v

. The neck 2 is also 'provi ded'with a vertical partition or wall 8 which is preferably -of fV-shape and formed integrally with the 'innerwall of the neck2, the stud 4; and the 193i. Serial No. 544,443.

partition 3. The top of the'wall 8 terminates in the plane of the top of the neck 2.

VA cap'9 is rotatably mounted on the spindle 5 and is provided with a downwardly eX;

tending skirt 10 which embraces-the neck The spindle 5 extends through an opening 11 provided therefor in the top 'ofthe cap A- semi-circular body portion 12 depends from the top of the cap '9 into the neck 2 ,"as indicated in the drawings, the. periphery and bottom "thereof being shaped soas to slidably fit the inner wall of the neck '2 and the top of the partition3'respectively.

The center of the bodyp'ortion 12 is preferably provided with an arcuate'recess 13 which is adapted to slide around the periphery of the stud 4. I

The opening 7 and the bodyportion 12 are positioned with respect "to each other so that when the "cap is closed, one side of the body portioni'engages a side of the V-shaped Wall 8 and the other side lies alongside of the hole 7, uncovering the same as shown by Fig. 4.

The 'ne'ck 2 is also provided with a horizontal hole v14 in the side thereof adjacent one side of the V-shaped wall 8'in spaced rea lation to the vertical hole 7 so that a measuring space15 is provided,,when'the'cap is in its closed position, "between the V-shaped wall 8 and the body portion12. A peripheral slot 16 is provided in theskirt '10 which is adapted ito'un'coverthehole 14 in the side of the neck2 when the 'cap 9 is "turned from its extremeclosed position, as's'hown by Fig. 4, around to its extreme open position, as shown by Fig. 3. The slot '16 ispreferably approximately equalin length to itheperipher-a1 .movement of the skirt 310 plus the. die

ameter o f the hole 14. v v I In operatiomthe tube is squeezed with: the cap closed, as'shown 'by ,FigJlfandthe con EM Yer-ms from through the hole 14 in the side of the skirt.

The contents of the measuring space 15 are completely ejected by turning the cap to its complete open position, as shown by Fig. 3. The cap may be left in this position until it is desired touse the tube again or the cap may be turned to its refilling position, as indicated by Fig. l. The operation of the measuring may be repeated whenand as often as desired.

It is to be noted that the closure above described provides an efficient seal when the cap is either in its extreme closed or in its extreme open positions. In any position, however, at least'one of the

openings

7 or 14 is closed thereby sealing the contents of the tube 1 from the atmosphere and consequent deterioration.

I lVhile I have described my improved closure in connection with a collapsible tube, it will be apparent to those skilled in the art that it may be used with other containers such as bottles, uncollapsible tubes or the like. Furthermore, if desired the device may be used by itself for measuring certain quantities of any desired material. In this use, the neck 2 and the cap would take the form of telescoped cylindrical cups in which case either opening could be the inlet opening with the other opening the outlet opening.

a As shown by Fig. 1, the cap 9 is preferably provided with a projecting knurled rim 17 r around the upper periphery thereof whereby the cap may be easily grasped and turned with the fingers. This is especially desirable where the cap happens to be slippery or wet.

Various changes may be made in. the details of construction of my preferred embodiment without departing from the spirit of the invent-ion which is intended to be limited only by the prior art and the scope of the following claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is z V 1. A collapsible tube having a cylindrical neck, said neck having a horizontal partition,

said partition having a vertical stud concentrio with said neck and extending beyond the top thereof, saidhorizontal partition having a vertical hole therein, a vertical V-shaped wall in said neck extending horizontally from j the inner periphery thereof to said stud and vertically from said partition to the top of said neck, said neck having a horizontal hole therein adjacent said wall, a cap rotatably mounted onsaid stud having a skirt slidably embracing said neck and a semi-circular body portion depending into said neck, the bottom and sides thereof being shaped to slidably fit the top of said partition and the inner surface of said neck respectively, said skirt having a horizontal slot therein adapted to cooperate with the hole in said neck whereby when the cap is closed said neck may be filled by pressing the tube and when said cap is rotated said slot permits said body portion to eject the contents of said neck through said horizontal hole, at the same time covering the top ofsaid vertical hole in said partition.

2. A collapsible tube having a cylindrical neck, said neck having a horizontal partition, said partition having a vertical stud concentrio with said neck having a spindle of reduced diameter and extending beyond the top thereof, said spindle having a laterally projecting head, said horizontal partition having a vertical hole therein, a vertical V-shaped wall in said neck extending horizontally from the inner periphery thereof to saidstud and vertically from said partition to the top of said neck, said neck having a horizontal hole therein adjacent said wall, a cap rotatably mounted on said stud having a hole accommodating said spindle,'a skirtslidably embracing said neck and a semi-circular body portion depending into said neck, the bottom and sides thereof being shaped to slidably fit the top of said partition and the inner surface of said neck respectively, said skirt having a horizontal slot therein adapted to cooperate with the hole in said neck, whereby when the cap is closed said neck may be filled by pressing the tube and when said cap is rotated said slot permits said body portion to eject the contents of said neck through said horizontal hole, at the same time covering the top of said verticalhole in said partition.

3. A collapsible tube having a cylindrical neck and an integral partition at the bottom thereof having a stud thereon, a hole therein and a vertical wall, a ca rotatably mounted on said stud having a siirt embracing said neck and a body portion depending into said neck, said neck having a hole therein, said skirt having a peripheral slot coacting with said hole whereby when said cap is closed said neck may be filled by forcing contents of the tube through said hole in said partition, and when said cap is turned from said closed position said body portion covers said hole in said partition, said slot uncovers said hole in said neck, andsaid body portion compresses the contents of said neckand causes it to be ejected out of said hole in said neck, the length of said slot being equal to the peripheral travel of said cap plus the diameter of said hole in said neck.

4:- In combination, a pair of relatively rotatable telescoping cylindrical cups for measuring material, one of saidcups having a hole in the wall thereof and the other cup having a v hole in the bottom thereof, said cups having coacting integral partitions therein forming a measuring space between said holes, said cup having a hole in the bottom thereof also having a peripheral slot therein coacting with said hole in the wall of the other cup, wherehand. 7
