` lPASTE TUBE GAP Filed Apil 9, 1934 E l l In'venlor `/Illorney Patented Nov. 13,- 1934 1,980.6# PASTE TUBE cnr I y .ames W. Tanfleld, Jersey City, N. J. Application April 9, 1934, serial Nu. '119,758
This invention relates to a. cap for paste tubes, the general object of the invention being to provide the cap with a slit and to form the cap of resilient material whereby pressure upon the tube will force some of the contents through the slit and when the pressure is released, the vacuum occurring in the tube will close the slit.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and speciiically pointed out in the appended claim.
In describing the invention infdetail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-
Figure lis an eleva-tion showing the improved cap on a paste tube.
Figure 2 is a top planview of Figure 1.
Figure 3 is a section on line 3 3 of Figure 2.
Figure 4 is a view similar to Figure 3, but showing a modification.
In this drawing, the letter A indicates the tube and the letter B indicates a cap for fitting over the neck of the tube, said cap being formed of resilient material and having an internal bead 1 at its open end for engaging a groove 2 formed in the neck, this groove and rib holding the cap on the neck.
A diagonally arranged slit 3 is formed in the central part oi' the top portion of the cap and a pairof short slits 4 diverge from points adjacent the ends of the slit 3, as shown in Figure 2.
As shown in Figure 3, one wall of vthe slit 3 overlaps the other wall and the slits 4 are associated with the overlapping wall. Thus when the tube is pressed upon, some of the contents will press against the upper part of the cap so as to not only separate the walls of the slit 3 apart,
but also raise the part 5 formed by the overlapv ping Wall of the slit 3 and the slits '4 so that the v material can readily pass from rthe cap upon the brush or other article which is to receive the contents of the tube. The part 5 acts as a lip and moves upwardly when pressure comes upon the same. As soon as the pressure is removed from the tube, a slight vacuum occurs therein and this will pull the tongue or lip 5 downwardly and thus close the slit 3 in a. vsubstantially air-tight manner. 1
In Figure 4, the cap B is slipped over an internally threaded collar 6 which is adapted to be threaded to the threaded' neck 6 of a tube A', lso that the invention can be used in place of an ordinary threaded cap. The collar is -iormed with the ange '7 at its lower end which is adapted to be turned up over the lower end of the cap to fasten the cap to the collar.
It is thought troni the foregoing description that the advantages and novel features ot the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts. provided 9 that such changes fall within the scope of the appended claim.
What is claimed is: A cap for a. paste tube comprising a. body o! resilient material and including a flange for ilt- 85,
' ting over the neck of a paste tube and a top part.
said top part having a diametrically arranged slit therein, the ends of which terminate in spaced relation from the ilange, said slit sloping from the upper face of the top part to the lower face 9 thereof, whereby one wall ot the slit overlaps the other wall, the overlapping wall 'forming a lip and said top part having a pair of short slits therein for separating the ends of the lip forming part from adjacent parts of said top part.
