5Claims. (ca. 22140) -'Ihisfinvention have. to dispensing devices.

The invention has for an object the provision of a device adapted to be secured to the threaded neck of a' tube, such as the, neck of a colla psible tube holding tooth paste, shaving cream, or.

' other substance, adapted to'be exuded through ed neck and adapted to allow the opening or the the neck when the tube is rolled or otherwise compressed, said dispensing device taking the place of the ordinary cap received on the threadneckto be positioned so that material may be exuded therethrough or, upon releasing the tube,

. to permit the-tube to have the neck thereof automatically closed.

The present device contemplates the use of a bracket adapted. to be secured to some object,

and a pair of arms pivoted to said bracket, one

of whicharms is threaded for, engagement with the threads of the neck oi! a collapsible tube, and the other oi. whicharms cooperates'with the end of theneck to close the opening in the same, the

relationship being such that when the tube is a manually moved, the tube carrying arm will move with said tube away from the closure arm and when the tube is allowed to drop under gravity,

the closure arm is positioned directly over the I One dimculty with devices now known to the inventor which are adapted to take the place of the usual cap on tubes is due to the expense of constructing such a device. The present inv vention is very cheap to manufacture in that it costs but a few cents and can, therefore, be'readily placed in a box by the manufacturer or seller of dental or shaving creams without greatly adding to the normal expense of the cream.

In the drawing Figure 1 is a side elevation of the device, a certain portion being shown in section to illustrate connection of the device with the threaded neck of a collapsible tube,

Figure 2 is a front elevation of the device associated with a collapsible tube,

a Figure 3 is a fragmentary side elevation of the device, the tube being raised so that the content thereof may be exuded through the neck upon compressing the tube, and,

Figure 4 is a sectional view on the line 4-4 of Flgurel.

Referring now with particularity to the drawing, I indicates the improved dispensing device as anentirety, and 2 a collapsible tube of the type employed for dental and shaving creams;

and wherein 3 is a threaded neck of said tube.

The device I includes a bracket 4 which may have two ofiset parallel portions 5 andiiwith an integrally formed connecting piece I, the portion 5 having through bores whereby screws may be passed therethrough "and received in some supporting member 8, thereby holding the bracket in substantially a vertical position. The portion 6 of said bracket is provided with a transverse bore 9 and the end of said portion provided with a shoulder III. A pair of arms ii and i2 are swingingly secured on opposite sides of the por- .tion .5 of the bracket through the medium of a stud-or pin i3. 'The arm II is given a structural twist at I4 and provided with a threaded bore i5 adapted to receive the threaded neck 3 of the tube 2. The arm. II is termed the tube carrying member. The arm i2 is given a structural twist at 16 and formed with a concave-convex protuberance I! which when the arms are cooperating, isin alignment with the threaded opening ii. A coil spring i8 has one end thereof passed through an opening in the part 6 of the bracket, shown at l9 in'Figure 2, and the opposite end of said spring is passed through an opening in the arm l2, as shown at 29. This coil spring at all times urges the arm to swing in a clockwise direction relative to the bracket, rotation being limited by the arm engaging the shoulder ill, see Figure 3.

The operation, uses and advantages of the invention just described are as follows:

The bracket is mounted so as to be in a vertical position relative to the supporting member 8, as shown in Figures 1 to 3, inclusive. The cap that is usually supplied with collapsible tubes is removed, and the neck threaded into the threaded opening l5 of the arm II. This operation is conveniently accomplished by swinging the arm II tothe position shown in Figure 3. Upon dropping the-tube, the same will fall under gravity and a portion of the neck of the tube which projects beyond the surface 2i will be received within the confines of the member I! as, for instance, illustrated in Figures 1 and 4. When the neck is received as aforesaid, the arm i2 will be moved from engagement with the shoulder ill, see Figure 1. It will be remembered that the arm i2 is spring actuated so that the portion I i is at all times urged to cover the outlet of the neck of thetube.

When it is desired to dispense any of the ma-- terial from the tube, the tube may be swung, together with the arm ll, about the pivot point of said arm to the position shown in Figure 3, whereupon pressure upon the tube will cause the contents to be exuded therefrom, as indicated by the dotted lines at 22. When the tube is dropped, any extra material at the outlet end of the neck of the tube will not be removed therefrom by the member I! unless, of course, considerable of the material .from said tube was left projecting from the opening in the neck. It is expected that the user of the devicewiil, under ordinary circumstances, wipe the tube clean with a brush or other article so that pastewill not build up within the member l1. However, it is evident that even if the material does build up within the member I! that the construction of the device is such that direct air contact with said material is prevented so that the material will not dry and become hard;

I claim:

1. In a device of the character disclosed, a bracket adapted to be vertically, secured to a supporting structure, a pin carried by one end of said bracket, a pair of arms positioned on opposite sides of said bracket and swingingly mounted on said pin, one of said arms formed with a threaded bore for threaded engagement with the neck of a collapsible tube and the other of said arms provided with a concave-convex cap, and means normally urging said last named arm to position said cap over the threaded opening of the other arm.

2. In a device of the character disclosed, a bracket adapted to be secured to a supporting structure, an arm swingingly mounted at one end 01 said bracket, said arm formed with a threaded bore to receive the threaded neck of a collapsible tube and said arm normally being swung from a vertical position under influence of gravity when a collapsible tube is secured thereto; a second arm swingin lv mounted to said bracket.

said second arm formed with a concave-convex structure, an arm swingingly mounted at one end of said bracket, said arm formed with a threaded bore to receive the threaded neck of a collapsible tube and said arm normally being swung from a vertical position under influence of gravity when a collapsible tube is secured thereto; a second arm swingingly mounted to said bracket, said second arm formed with a 'concavo-convex cap, resilient means urging said arm and its cap to overlie the opening of the first arm and the neck of any tube secured thereto. and stop means for said bracket for limiting movement of the resiliently urged arm in one direction.

4. A device of the character disclosed, including a bracket adaptedto be vertically secured to a support, a pin carried by said bracket, a pair of arms swingingly mounted on said pin, one of said arms being formed with a threaded bore into which the threaded neck of a collapsible tube is screw seated, said other arm being formed with a cap to receive the projecting end of the neck of said collapsible tube when said first arm is swung against said'second arm, under the influence of the weight of said collapsible tube, and a spring coiled around said pin with one end of said spring connected to said bracket and the other end of said spring connected to said second arm for urging said second arm toward said first arm to position said cap over the projecting end portion of said neck of said collapsible tube.

5. A device as claimed in claim 4 including a stop on said bracket to be engaged by said second arm to limit the movement of said arm under the influence of said spring.
