Application August 31, 1940', Serial No. 355,079
1 Claim.
The present invention relates to new and useful improvements in paste tubes and has for its primary object to provide a closure adapted for automatically opening to permit discharge of the contents of the tube'by pressure created in the tube and also to provide spring means for yieldably urging the closure into a closed position.
A further object is to provide a paste tube closure of this character of simple and practical construction, which is neat and attractive in appearance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure 1 is a fragmentary side elevational view 01' a paste tube illustrating the closure mounted in position on the neck of the tube,
Figure 2 is a top plan view, and
Figure 3 is a vertical sectional view therethrough.
Referring now to the drawing in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a paste tube of conventional collapsible construction and including the neck portion 6. The neck 6 is of square or other polygonal shape in cross section and has its top, as well as one of its side walls open.
snugly fitted in the open side wall of the neck is the closure 1 of substantially triangular shape, one wall of the closure being normally perpendicular and flush with the edges of the open side of the neck, the top of the closure being normally flush with the top of the neck and the bottom of the closure indicated at 8 being disposed inwardly of the neck and inclined upwardly toward the side wall of the neck opposite from the open side thereof. The upper edge of the inclined bottom 8 of the closure rests against the upper edge of the neck as shown at 9.
The closure is normally urged into a closed I position by means of a coil spring l0 which has one end indicated at H secured to the outer surface of the tube by means of a spot of solder l2 while the other end l3 of the spring is likewise secured to the perpendicular side of the closure 1 by means of a spot of solder I4.
From an inspection of Figure 3 of the drawing it will be apparent that the inclined bottom 8 of the closure will be subjected to internal pressure caused by the collapsing of the tube whereby to force the upper free end of the closure outwardly against the tension of the spring l0. When pressure is released the spring 10 will serve to close the tube in the position as shown.
It is believed the details of construction, manher of operation and advantages of the device will be readily understood from the foregoing without further detailed explanation.
Having thus described the invention, what I claim is A collapsible tube closure comprising in combination a neck for the tube of polygonal shape in cross section, the top of the neck and one side wall thereof being disposed at right angles and open substantially throughout the entire length of the neck, a closure in the form of a triangular-prism positioned in the open top and side walls with the top and side of the closure disposed at right angles to one another and flush with the opening at the top and sides of the neck, the bottom of the closure being inclined and responsive to internal pressure for opening the closure, and a coil spring having one end secured to the side wall of the closure adjacent its bottom edge and having the other end of the spring se-'-- cured to the tube beneath the neck, said coil spring constituting a pivotal support for swinging the closure about the axis of the spring.
