1 Claim.

This invention relates to a dispensing cap which is particularly designed to be used in conjunction with a collapsible toothpaste or shaving cream tube or tubes holding a fluid or semi-fluid material.

An object of the invention is to provide a dispensing cap that may be distributed with the cap attached in position on the tube or may be sold separately from the tube.

The cap embodying the invention is intended to replace the cap now used on collapsible tubes and, when used, the cap will prevent loss and once fixed in place, there remains nothing to be removed from the tube to gain access to the contents thereof.

The new cap is sanitary in use, attractive in design, and will not easily be damaged to prevent full use of the cap.

With the above and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawing in which:

Figure 1 is a top plan view of a cap embodying the invention;

Figure 2 is an elevational side view of the cap;

Figure 3 is an elevational front view of the cap;

Figure 4 is a perspective view of the cap with the lid removed and Figure 5 is a vertical, sectional view on the line 55 of Figure 1.

Referring more in detail to the drawing, the reference numeral it designates a dispensing cap constructed in accordance with the invention.

The cap It comprises a circular body H, provided at its bottom surface with a threaded bore l2, Which is adapted to be screwed onto the threaded neck It of a collapsible tube [4.

The body H has formed on its upper surface, an offset spout portion i5, having a straight front face [6 and the straight side walls I! and I1 that merge into the curved rear face l8.

The top of the portion i5 is partially straight, as at 9, and partially curves downwardly as at 28, to merge into the curved rear face l8.

Extending at a forwardly diverging angle in the body H and portion 15, is a passageway 2|. The passageway, at its lowest end, is round in cross section as at 22, and merges into a U-shaped cross section at its upper end as at 23. The U- shaped formation provides a cuttin edge 24 for the material within the tube M.

A lid or cover 25 is provided for the passageway 2|, and a pin 26, passingthrough the transverse opening 21 in the portion l5 and the lid or cover 25, pivotally retains the lid on th portion l5.

The lid is formed to cover the top, side and rear surface of the portion l5 leaving the front surface IB free.

Centrally 0f the body II, in the rear of the central line of the portion I5, ther is provided a circular seat 28, to receive the coil spring 29. The spring 29 engaging the rear of the cap 25, will force the cap into closed relation with the passageway 2|.

All the edges of the cap are rounded to present an attractive appearance, as may be seen from the drawings.

In use with the cap screwed into place on the tube l I, pressure on the tube will force the contents thereof into engagement with the lid 25. Further pressure on the tube will force the contents to lift the lid and be dispensed outwardly of the passageway 2|. The quantity desired is determined by the length of time pressure is maintained on the tube. Upon release Of pressure on the tube, the spring 29 will force the lid closed against the cutting edge 24 to stop the flow of the contents of the tube.

The cap may be made of plastic material or die cast metal. It may be formed as previously described, or it may be formed permanently at tached to the tube.

It is believed that from the foregoing description, the manner of construction and operation of the cap will be apparent to those skilled in the art, and it is to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to. provided they fall within the spirit of the invention or the scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

A dispensing cap of the type described, for use with a collapsible tube having a, threaded connection on the end thereof, comprising a body portion, a threaded bore in the bottom surface thereof adapted to engage the connection on the tube, an offset spout portion on the top surface of said body portion, said spout portion having a straight front face and a curved rear face with the side walls bein straight and merging into said curved rear face, an angularly disposed passageway extending through said body portion and said spout portion and terminating adjacent the upper edge of the front face, th lower end of th p geway being round in cross section 3 and the'upper end of said passageway being U- shaped in cross section, the angularity and shape of the upper end forming a cutting edge on said spout portion, a lid pivotally mounted on said spout portion, and said lid having an open front Wall and being formed to cover the top, sides and rear surfaces of said spout portion, the body portion having a circular seat at the rear of said spout portion and a spring mounted in th circular seat in said body portion and engaging the portion of said lid covering the rear face of the body portion to force said lid into closing relation with said passageway.
