UNITED STATES PATENT OFFICE.
Application filed November 3, 1921. Serial No. 512,528.
To all whom it may concern:
Be it known that I, CLAUDE TSCHIFFELY,
.a citizen of the United States, residing at Washington, in the District of Columbia,
have invented certain new and useful Improveanents in Collapsible Tubes, of which the following is a specification.
My said invention relates to a collapsible tube for liquids or semi-liquids such as tooth prevent ready disengagement of the capfrom the tube.
Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts.
Figure 1 is an elevation of a collapsible tube and its cap, the latter being in position for attachment to the tube,
Figure 2 is a top View in closed position.
Figure 3 a horizontal section through the cap and the neck of the tube, and
Figure 4 is a partial vertical section of the device.
Figure 5 is a sectional view through the cap when removed from the tube showing the manner in which the top of the cap bulges downwardly.
In the drawings .10 indicates a collapsible tube of conventional form having at its up per end a threaded neck 11. An internally threaded cap 12 is adapted to be screwed on the neck, the cap bein externally milled or roughened in usual fas ion. The cap has an aperture at 13 adapted to register in one position with a corresponding aperture in said neck, the latter being otherwise closed at the top by a transversely extending portion. or plate 14. The top of the cap about the aperture 13is downwardly beveled as shown at 15 to form a cutting edge ada ted to lie closely against the plate 14, and th the cap may, bulge downward as shown in Figure 5 and be slightly resilient to maintain contact between the same and the plate 14. When the apertures are brought together by screwing down the cap the bulged top of the cap is flattened by the top of the-tube as shown. in Figure 4. When the cap is un-' screwed the resiliency of the top of the cap e upper part of i will restore the bulge and insure close contact between the top of the tube and the cap so as to obtain a clean cuttingaction. This cutting edge is intended to sever the mate rial extruded from the tube from that remaining and if such material is sufficientlyhard it will make a clean cut therethrough separating the extruded part from the remaining part and at the same time preventing waste of the material. Preferably the thread will be of low pitch so that the up or down movement of the cap during the partial revolution necessary to bring the two apertures into or out of register will be very limited in extent.
A portion of the thread 11 is cut away at one side of the neck as indicated at 16 and after the cap has been screwed down thereon a portion of the cap is punched in as at 17. This portion forms an abutment which will permit the cap to be rotated through a sector, here shown as approximately a tpliarter revolution, but will strike against t e end of the remaining thread and prevent further revolution. In ordinar cases the material of the cap and the tube 15, however, sufiiciently soft so that: the internal abutment at 17 will crumble if sufiicient force is used and thus permit removal of the ca should this be desirable.
. Various modifications of my device will suggest themselves to those skilled in the art and therefore I do not limit myself to what is here shown and described but only as indicated in the appended claims.
Having thus fully described mv said invention, what I clalm as new an desire to secure byLet-ters Patent, is:
1. A'disp'ensing device having a threaded neck, a threaded cap connected thereto, said neck and cap having correspo-ndingapertures and means for placing the apertured top of the cap under a tension whenever the top is screwed "onthe cap to register the said'apertures, substantially as set forth.
2. A collapsible tube having a threaded neck, a threaded cap therefor, a segment of one of the threads being omitted and an inwardly projecting abutment on the other member ada ted to move in the space left by said omitted thread segment, substantially as set forth.
3. A collapsible tube having an externall threaded neck, a caglhaving internal threa s for engagement wit said neck, a portion of I one of said threads being omitted, and an abutment on the opposing member adapted to move in the space left by the omitted thread, substantially as set forth.
4. A dispensing device having a threaded neck, a threaded cap connected thereto the top of said cap being curved inwardly and provided with an aperture formed with a cutting edge said neck having a flat face engaging said curved portion of the cap and providedwith an aperture, and means incident to the rotation of the cap on the neck to register said apertures and distort and place under tension the top of the cap, substantially as set forth.
5. A container having a neck of unbroken cylindrical contour at the'inside and having a helical outer thread 'a segment of one con- In witness whereof, I have hereunto set' my hand and seal at Washin ton, District of Columbia, this 3rd day of ovemher, A. D. nineteen hundred and twenty one.
