Description
Nov. 17, 1936. G. J. WALTHER COLLAPSIBLE TUBE CLOSURE Filed Jan. 29, 1936 atented cm. 17, 1936 "TED STATES PATENT OFFICE This invention appertains to new and useful improvements in closures for collapsible tubes, the principal object of the invention being to provide a cap constructed of flexible material, wherein the discharge opening is normally closed, but which will open automatically when the contents of the tube are placed under pressure, as when the tube is compressed by hand, thus permitting a discharge of the paste-or other material in the tube.
Other important objects and advantages of the invention will, become apparentto the reader of the following specification.
In the drawing:
Figure 1 represents a fragmentary side elevational view showing the cap about to be placed on a tube. 1
Figure 2 is a fragmentary detailed sectional view showing the cap in closed position.
Figure 3 represents a fragmentary detailed sectional view showing the cap in open position.
Figure 4 represents a perspective sectional view of the cap.
Referring'to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 represents a collapsible tube of conventional construction, the same being provided with the vneck portion 6 having the head or shoulder 1 extending circumferentially on the same.
The top portion 9 of the cap is provided with a short slit l2 which forms the outlet opening, while below this depends the tubular formation l3 having the beveled edge i4.
It can now be seen, that when the contents of the tube 5 are placed under hand compression, the paste or other material in the tube is forced 10 through the neck 6 and into the tubular formation [8 where the pressure of the rubber material causesexpanslon thereof and consequent opening of the opening l2, thus permitting the ma- 'terial to discharge. 16
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as 20 claimed hereinafter.
Having thus described the invention, what is claimed as new is:
A cap for a collapsible tube comprising a cupshaped member of elastic material having a dis- 25 charge slit in the top thereof, the elasticity of the cap normally maintaining the slit closed, and a depending tubular formation in the cap, said formation depending from the upper portion of the cap in alignment with the slit and having 30 relatively thin walls of elastic material disposed in spaced concentric relation with the walls of the cap and responsive to pressure surrounding the tubular formation to open the slit.
GEORGE J. WALTHER.
