COLLAPS IBLE TUBE CAP Filed July 22, 1952 Z759. ffy? fhomasflZzLZZ tams INVENTOR ATTOR N EY Patented Aug. 15, 1933 UNITED STATES PATENT OFFICE' COLLAPSIBLETUBE CAP Thomas Williams, New Castle, Pa.

Application July 22, 1932. Serial No. 624,093

3 Claims. (Cl. 221-60) This invention relates to' caps or closures for collapsible tubes and like containers and has for the primary object, the provision of a device of the above stated character which will efficiently exclude dirt and other foreign matter from the interior of the tube and prevent evaporation of the contents of said tube and which may be easily and quickly moved to open the tube and still remain attached thereto for preventing loss or displacement of the cap.

With this and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following descriptionand accompanying drawing, in which Figure 1 is a side elevation illustrating a collapsible tube with a cap applied thereto and constructed in accordance with my invention.

Figure 2 is a fragmentary side elevation taken at right angles to Figure 1.

Figure 3 is a fragmentary side elevation illustrating the cap in an opened position.

Figure 4 is a sectional View taken on the line 44 of Figure 1.

Figure 5 is a fragmentary perspective view illustrating the discharge neck.

Figure 6 is a sectional view illustrating means of anchoring a gasket in the cap.

Figure 7 is a fragmentary sectional view illustrating a modified form of my invention in which the gasket is anchored to the discharge neck.

Figure 8 is a sectional view illustrating a modified form of cap.

Figure 9 is a fragmentary side elevation, showing a modified form of securing means of the gasket to the discharge neck.

Referring in detail to the drawing, the numeral 1 indicates a conventional type of collapsible tube and has formed integrally therewith a discharge neck 2 of substantially rectangular shape in cross section and the top wall thereof is provided with a discharge opening 3 whereby the contents of the tube may be dispensed in the usual manner.

Opposite faces of the neck 2 have formed therein substantially V-shaped grooves 4 to be engaged by inwardly extending projections 5 formed on' the side walls 6 of a closure or cap 7. The V- shaped grooves 4 form in the neck 2 locking shoulders 8 which are engaged by the projections 5 to secure the cap in position for closing the opening 3. A gasket9 is mounted against the top wall of the cap between the side walls 6 thereof for engagement with the top wall of the neck. The gasket 9 is constructed of yieldable material such as spongy rubber and is adapted to yield when the projections 5 are moved into engagement with the shoulders 8 and the natural expansible qualities of the gasket against the top wall of the neck have a tendency to retain the projections 5 against the shoulders 8, consequently retaining the cap in a position to efiiciently seal the opening 3.

The cap is offset as shown at 9' to fit in a slot of the gasket 9 to prevent displacement thereof. The discharge neck is provided with grooves 10' to receive the projections 5 to aid in guiding the latter into the grooves 4 during the application of the cap to the neck.

The side walls 6 of the cap taper toward the projections 5 and said side walls also are offset and roughened to form finger grips 10.

The gasket 9 may be secured to the neck instead of the cap as shown by either Figures 7 or 9. The projections 5 may be shaped as shown in Figure 8.

To release the cap from a closed position, the top wall of the top is pressed downwardly, compressing the gasket and the projections 5 are moved laterally out of engagement with the shoulders 8, permitting the cap to be swung or tilted to one side of the neck as shown in Figure 3. The cap when in this position allows the contents of the tube 1 to be freely dispensed with the cap still attached to the neck so as to prevent displacement or loss thereof.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of my invention, as claimed.

Having thus described my invention, what I claim is:

1. A cap for tubes comprising a neck of rectangular shape in cross section and having a discharge opening, a closure consisting of top and side walls to fit over the neck for closing the discharge opening, said neck having in opposite faces thereof V-shaped grooves forming shoulders, and projections on the side walls of the closure element and fitting in said grooves to slidably connect the closure element to the neck and adapted to engage the shoulders for drawing the top wall of the closure element towards the discharge opening in the neck.

2. A cap for tubes comprising a neck of rectangular shape in cross section and having a discharge opening, a closure consisting of top and side walls to fit over the neck for closing the discharge opening, said neck having in opposite faces thereof V-shaped grooves forming shoulders, projections on the side walls of the closure element and fitting in said grooves to slidably connect the closure element to the neck and adapted to engage the shoulders for drawing the top wall of the closure element towards the discharge opening in the neck, and a yieldable gasket mounted between the top and side walls of the closure element to engage the neck.

3. A cap for tubes comprising a neck of rectangular shape in cross section and having a discharge opening, a closure consisting of top and side walls to fit over the neck for closing the discharge opening, said neck having in opposite faces thereof V-shapcd grooves forming shoulders, projections on the side walls of the closure element and fitting in said grooves to slidably connect the closure element to the neck and adapted to engage the shoulders for drawing the top wall of the closure element towards the discharge opening in the neck, a yieldable gasket mounted between the top and side walls of the closure element to engage the neck, said side walls of the closure element being offset and roughened to form finger pieces.
