cnosonn FOR COLLAPSIBLE TUBES.
Application filed June 8,
' This invention relates to a closure for a collapsible tube.
The general object of the invention is to provide an efficient automatic valve closure for collapsible tubes.
A specific object of the invention is to provide an elastic closure member for a collapsible tube wherein the closure comprises a rubber cap or nipple having a slit cut therein to afford an automatic closing valve.
Another object of the invention is to provide a rubber closure cap having a slit which is cut therein while the rubber is stretched.
Other objects of the invention will be ap parent from the following description taken in connection with the accompanying drawings, wherein:
Fig. 1 is a perspective view showing my invention applied to a collapsible tube;
Fig. 2 is a longitudinal section through the closure;
Fig. 3 is a bottom view of the closure;
Fig. 4 is a longitudinal sectional view through the closure and tube;
Fig. 5 is a view similar to Fig. 4 showing the manner in which the material is extruded;
Fig. 6 is a top plan and Fig. 7 is a side elevation showing the manner in which the rubber is placed under tension and the slit cut;
Fig. 8 is a sectional view through a tube and closure showing the closure as provided with internal threads;
Fig. 9 is a sectional view through the closure shown in Fig. 7;
Fig. 10 is a bottom view of the closure shown in Fig. 8, and
Fig. 11 is a central sectional view showing a slight modification of my invention.
eferring to the drawing by reference characters, I have shown a collapsible tube 'at 10. This tube is preferably soft and flex- 'ible and may serve as a receptacle for dentifrice, shaving cream, paste, or other similar material. The tube is shown as provided 1926. Serial No. 114,446.
with a relatively stiff end portion 11 upon which a stiff neck 12 is arranged.
A cap embodying the features of my in- Y vention is shown at 14. This cap includes a body portion which is preferably cylindrical and which has a dome-shaped end portion. The closure shown is of uniform thickness and is preferably made of a good grade of rubber.
The closure is provided with a slit 15 which is preferably formed as shown in Figs. 6 and 7 by stretching the rubber near the end of the cap with the v fingers 16 or with other means until it is in a taut condition and then inserting a knife 19 to cut a narrow slit. This provides a slit which has a strong tendency to close whereby the material being extruded will be cut off as soon as the tube is released from pressure, thereby providing a sanitary closure.
In Fig. 7 I show in dotted line at 19 the end of the tube before being stretched and at 19 I'show a knife which when pushed into the rubber cuts a slit and causes the end 7 of the tubeto assume the position shown in solid lines in Fig. 7. When the end of the tube is released the walls of the slit come together as shown in Fi 3.
In Fig. 8 I show the closure cap as provided with internal threads 18 which mate with the threads on the neck 12. The slit 15 of this modification is preferably formed in the manner as previously described.
In Fig. 10 I show the closure as fashioned in the shape of a nursery bottle nipple 20 wherein the closure isprovided with a bead 21. This closure has a slit15 made after the fashion. previously described. In this modification the material is of uniform thickness throughout substantially all of the cap and the slit is made by stretching the rubber and cutting it with a sharp instrument while stretched as previously described.
Although I have shown the neck of the collapsible tube as threaded, it will be understood that this neck may present a smooth n a I member, means to hold said closure on said 10 body and over said discharge opening, said closure having its elastic wall perforated vyhile under tension to form a discharge slit which closes when the tension is released.
In testimony whereof, I hereunto afiix my 15 signature.
