CLOSURE FOR RECEPTACLES Filed Dec. 15 1931 INVENTOR' Patented July 10, 1934 umrso TA res =1 ATENFF E 3 Claims.
This invention relates to closures .for receptacles, and .more especially to closures for..collapsible tubes which discharge a material .contained therein upon compression of the tube.
In general, it is an object of the invention to provide a device of the character described which will eficiently perform the purpose for which it is intended, which is simple and economical .of construction, which can be expeditiously and conveniently manipulated, and which is readily manufactured and assembled.
Another object of theinventionisto providea collapsible tube with a resilient member for permitting extrusion :which is readily accessible for repair.
Another object of the invention is to provide a collapsible tube with a resilient member for permitting extrusion, so arranged that any unused material is easily removed from said member.
Another object of the invention is to provide a collapsible tube with a resilient member for permitting extrusion, the action of which is frictionless.
Another object of the invention is to provide a detachable cap for a collapsible tube and having an exterior resilient member for permitting extrusion through the cap.
Other objects of the invention will in part be obvious and will in part appear hereinafter.
The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.
For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:
Fig. 1 is a perspective view of a device embodying one form of the invention;
Fig. 2 is a cross section of a portion of the device shown in Fig. 1 taken along the lines 22;
Fig. 3 is a plan view in section of the device shown in Fig. 2 taken along the lines 3 -3;
Fig. 4 is a perspective View of a modified construction embodying the invention; and
Fig. 5 is a sectional view in elevation of another modified construction embodying the invention.
It is desirable that resilient means which cover the opening of a collapsible tube and which may be pushed away by the extruding material should be in such a position that they may be easily repaired. It is sometimes necessary in the case of toothpaste, for example, to remove dried material which ,prevents the means .from acting. .It .is of importance that there .be substantially .noiriction retarding the .functioning .of .the resilient closingmeans. Where guides .co-operate with the resilientmeans to .direct the flow .of material and/or. limit the resilient motiona better operation issecured. These attributes, among others, are to be found in-the devicedescribed below.
In the .exemplification .shown in theldrawing, ,10 is-aoasing. Athroat ortruncatedboss ll-on the casinghas a passage .12 ltherethroughleading totheuinterior of .the casing. Resilientmeans are provided toulieoverthe outside. of v the .endof the passage, such as a spring member 13. This may be suitably secured, for example, by having one end frictionally retained in a depression 14 in the casing. Guide members 15 may be provided to prevent the resilient member from being pushed too far away from the opening as material is ex truded from the casing. These may take the form of arms countersunk in the sides of the boss and extending over and slightly above the resilient member. The guides and spring member may be attached to the boss by any suitable means such as the ring 16.
In the modification shown in Fig. 4, the part of the resilient member which overlies the end of the passage 12 is countersunk in the top of the boss 11. The portions 17 of the top of the boss along the sides of the countersunk member, may be raised so that as the resilient member is raised, the extruded material is only permitted to pass out past the end thereof.
In the modification shown in Fig. 5, that portion of the device which provides the passageway is detachable from the main portion of the casing, for example, the detachable tube or cap 18 may be provided with threads 19 adapted to cooperate with similar threads 20 on the main casing. It may also have another threaded portion 21 to which a supplementary cap 22 may be fitted.
The passage 12 may be constricted at its outer end and so positioned as to direct the force of the material extruded therefrom against the end of the spring member 13, as shown, for example,
n Figs. 2 and 3, so that the leverage of the spring member against the orifice at the end of the passage may be a maximum.
The operation of the device is as follows: Pres sure against the walls of the casing causes the material contained therein to be extruded and to force back the resilient spring 13 against the guides 15. When pressure on the tube is removed the resilient spring returns to the position shown,
for example, in Fig. 2, closing the opening to the passage.
Where desired, and in connection with any of the modifications of the invention shown, the added covering cap, such as shown in Fig. 5 at 22, may be provided to protect the article during shipment and handling.
Since certain changes may be made in the above product and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
Having described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. Discharge means for a collapsible tube comprising a throat having a passage therethrough, a slot in the exterior surface of said throat and spaced from the end of said passage, 2. fiat spring retained in said slot and extending tightly over the end of said passage, said spring being adapted to move freely away from said end under the impetus of extruded material and being adapted to lie closely against the surface of said throat and across the passage therein at all other times, and means adapted to restrain excessive movement of said spring.
2. Discharge means for a collapsible tube comprising a throat having a smooth, unobstructed passage therethrough and a slot in the exterior surface thereof and spaced from the end of said passage and a flat spring retained in said slot and extending tightly over said end and adapted to move freely against the adjacent parts under the impetus of extruded material to provide an unobstructed orifice to said passage, said spring being adapted at all other times to fit tightly against the exterior surface of said throat and across said passage, and a pair of guides attached to said throat, extending into the upward path of said spring and adapted to limit the movement of said spring.
3. Discharge means for a collapsible tube comprising a throat having a smooth, unobstructed passage therethrough and a slot in the exterior surface thereof and spaced from the end of said passage and a fiat spring retained in said slot and extending tightly over said end and adapted to move freely against the adjacent parts under the impetus of extruded material to provide an unobstructed orifice to said passage, said spring being adapted at all other times to fit tightly against the exterior surface of said throat and across said passage, and a pair of guides attached to said throat, extending into the upward path of said spring and adapted to limit the movement of said spring, the walls of said passage near its outer end being shaped to direct the extruded material past the end of said spring.
