lclsim.

This invention relates to improvements in dispensers and has particular reference to a selfsealing attachment adapted to be used in conjunction with collapsible tubes or containers that retain therein, dental creams, shaving creams, ointments and other commodities usually sold in paste form.

A further object is to produce a device which will not become clogged during use.

10 A further object is to produce a device which is sanitary in that it fully protects the contents from outside contamination.

A still further object is to produce a device which is economical to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the' same,

Fig. 1 is a side elevation of an ordinary collapsible tube having my invention applied thereto,

Fig. 2 is an enlarged fragmentary cross-sectional detail view taken on the line 2-2 of Fig. 1,

Fig. 3 is a view similar to Fig. 2, showing the parts in open position, and

Fig. 4 is a cross-sectional view taken on the line 4-4 of Fig. 3,

It is common to expel toothpaste or like commodities from a collapsible tube which ordinarily is closed by a screw cap. Due to the fact that it is a separable member the cap is often dropped, lost, misplaced or through neglect may not be returned to the tube with the result that the paste upon the end of the tube is subject to contamination from outside sources, becomes sticky and it is to overcome these objects that I have devised my device.

In the accompanying drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates an ordinary collapsible tube having a reduced portion 6 and a threaded neck '7. This tube corresponds to the ordinary collapsible tube purchased with a threaded cap thereon. In use This telescoping member has a port 16 through which the contents of the tube may be dispensed.

The operation of my device is as follows:-- Assuming that my device is attached to the ordinary collapsible tube and the tube is pressed in the customary manner, the paste within the tube will pass around the spring 11 and between the coils thereof through the opening formed between ahnular shoulder 9 and into the telescoping member 14. As the paste fills up the space within the telescoping member and further pressure .is brought to bear upon the tube the spring 11 will yield so that the telescoping member 14 will move from the position of Fig. 2 to the position of Fig. 3, thus uncovering the port 16 and permitting the escape of the commodity. As soon as pressure is released from the tube, the spring 11 will return the telescoping member to its normal position within the tubular member thus closing the port 16 and entirely sealing the contents against outside influences.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, 89 size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:-

In a device of the character described, a tubulet member capable of being removably attached to a collapsible tube, a tubular telescoping member having a closed outer end and an open inner end and slidably positioned in said tubular member, the cylindrical wall of said telescoping member having a discharge port near its outer end, whereby the contents of said tube may be expressed through said tubular member and through said port of said telescoping member, a pin centrally securedin said closed end and extending into said tubular member, said tubular member having an annular shoulder formed therein, a spring interposed between said annular shoulder, and ahead formed on said pin, said spring tending to retain said telescoping member within said tubular member when the contents of said collapsible tube are not being expressed.

VANCE S. WILCOX.
