Application March 18, 1946, Serial N o; 655,096

This invention relates to new and useful improvements and structural refinements in dispcnsers, more specifically, to a device of the character herein described, in which a brush structure is connected to the outletofa collapsible tube of dental cream to provide what may be referred to 4as a fountain toothbrush.

apparent not only when used in the home, but

particularly when traveling, the dispenser being provided with a ventilated cover for the brush and with a resilient clip Whereby the entire assembly may be conveniently attached to wearing apparel.

A further object of the invention is to provide a dispenser in which the contents of the tube may be easily ejected and in which the tube when empty, may be readily replaced.

Another object of the invention is to provide a dispenser which may be quickly and easily disassembled for purposes of cleaning.

An additional object of the invention is to provide a dispenser which is of simple construction and Which will not easily become damaged.

A still further object of the invention is to provide a dispenser which will readily lend itself to economical manufacture.

With the above more important objects in view, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in Which:

Figure l is a longitudinal, cross-sectional view of the invention.

Figure 2 is a side elevation ofV the same.

Figure 3 is a top plan view of the brush assembly per se.

Figure 8 is a plan view of a flow regulator disc used in Fgure 7.

Like characters of reference are used to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawing's in detail, the invention consists of a tubular casing assuming substantially the form illustrated and designated by the general reference character Ili.4 One end of this casing is formed With a frusto-conicalv portion II, the latter in turn, be-

. ing provided With a central bore l2.

A collapsible tube IS, containing suitable dentifrice, is replaceably positioned in the casing IO, the threaded end portion 14 of this tube project- 'ing through'the bore l2.

The remaining end of the casing li] is of a somewhat enlarged outside diameter as indicated at IB and an annular groove I is formed in the portion l, to accommodate a suitable resilient clip ll of Conventional design, whereby the entire invention may be conveniently attached to wearing apparel.

An internal annular groove IB is formed adjacent the end of the casing IU and a longitudinally extending recess 19 connects the latter groove with the end of the casing. An ejecting knob 20 is formed on one side thereof with an integral extension 2l, this in turn, being provided with a radially projecting pin 22. It will be noted that by sliding this pin along the recess 19 into the groove l8, the knob 20 may be applied to the end of the casing, as shown in Figures 1 and 2. Furthermore, when the pin 22 engages the groove 18, the knob 2D and the associated extension 2| will be rotatably and removably retained in the end of the casing, as Will be clearly understood With reference to the accompanying drawings.

The extension 2l is also provided with an arcuate slot 23 and the closed end of the tube l3 is twist-ed to form a loop 24. This loop is removably engageable with the hook defined by the slot 23 in the extension 2 I, and it will be noted that by rotating the knob 2B, twisting motion will be imparted to the tube lfl and the contents thereof will be conveniently ejected.

The brush assembly used in the invention is designated generally by the reference character 25 and coinprises an elongated body 2% formed With an outiet passage Zf. This passage extends from the end of the body indicated by the character 2'8 and opens into an enlarged bowl or elonand provided Vwitha central .aperture ill.

3 gation 29 disposed medially the length of the side 3G of the body 26.

Suitable tufts of bristles 3! are also provided on this side of the body, the same being secured in position in any Conventional manner.

The remaining end of the passage 21 opens into a screW-threaded counter bore 32, Whereby the assembly 25 may be removably attached to the threaded pol-tion IA of the tube 1,3 and hence to the associated casing ID. The portion 23 of the body 26 may, if desired, be of a frusto-conical configuration, in order to constitute a continuation of the portion II of the `casing.

The removable cover for the brush assembly is designated generally by the reference character 33 and consists of a shell 34, configurated -substantially as shown, and provided With an opening 35 at one end thereof. The shell 34 is also formed With a plurality of ventilating openings or apertures 36 and with pairs of longitudinally vextending, inturnedvfianges 37, constituting .the

channels 31 The outervof the flanges .31 vare reinforced by the end cross-members 39 and by slidably iinserting the body 26 into Vthe channels 38, the shell Sliwill conveniently enclose the bristles 35, as is best shown in the accompanying When using a liquid dentifrice, the `rate-of flow of the same'to .the brushimay be effectively governed by a Vregulator disc dB, the .same being formed .from .rubber or vother .resilient material VThe disc li-Q is positioned in the inner end of the counter-bore 32 at the outlet of the tube .13 audit will be apparent that .the Aelastic properties Ainherent in the disc Will open or close the aperture (H in accordance With application or removal of pressure on the tube 13.

It is believed that the operation and use Vof the invention Will be clearly understood from the foregoing andfurther description thereof .at this point is therefore considered unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to Without departing from the spirit and scope of the invention as claimed.

What I claim as my invention is:

In a;dispenserfof the class described including 'a tubular casing and 'a eollapsible tube positioned in said casing and having a loop provided 'at one end thereof, a tube collapsing mechanism .comprising a knob rotatably positioned at one iend of said casing and provided integrally with aflat-sided and relatively narrow extension pro- Ajecting into the casing, said extension being ,formed'with an arcuate slot having open sides and an open end at one longitudinal edge of the extension Whereby the inner end portion of the extension constitutes an arcuate hook, said hook 'being slidably inserted in said loop vwhereby said ltube-may be axially twisted by .rotation :of said knob.
