Patented Get. 16, 1934 I VIUNITED STATES 1,977,537. g I CAP FoR CONTAINERS 'William Warmuth, Connellsville, Pa., assignor of one-fourth to'Arthurf B. Robbins, Gonnellsville, Pa.

Application September 2,1932, Serial'ld'o. 631,575 4 Claims; (cram-to) This invention relates .to closure caps for containers, and its general object is'to provide a valve cap primarily designed 'for collapsible tubes,but can be used on all types of containers p for controlling the dispensing of the contents thereof, without removing the cap from the container, and the cap is held associated with the container, with the result the cap cannot become lost or misplaced. V A further object of the invention is to provide a container closure cap of the dispensing valve typethat will control, the quantity dis pensed, merely by rotating the cap on the screw neck of the container andrwhen the cap .is completely closed, an air-tight connection is made, therefore the contents of the tube are kept/in the original as well as in a clean and sanitary condition.

Another object of the invention is to provide a-closure cap of the character set forth, that is simple in construction, is applicable to tubes now in general use, is inexpensive to manufacture and is extremely eificient in operation and service.-

v This invention also consists in certain other features of construction and in the combination and arrangement of theseveral parts,.to be hereinafterfully described, illustrated in the accompanying drawing and, specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is a fragmentary vertical sectional view taken through a collapsible tube illustrating one form of my invention applied thereto.

Figure 2 is a top plan view of the cap as shown in Figure 1.

Figure 3 is a sectional View taken approximately on line 33 of Figure 1, looking in the direction of the arrows.

Figure 4 is a sectional view illustrating the applied to a slightly different type of tube.

Figure 5 is a sectional view of a modified form of cap.

Figure 6 is a similar view of a further modified form.

Figure 7 illustrates a fragmentary portion of a still further modified form. 7

Referring to the drawing in detail, it will be noted that I have illustrated my cap applied that the cap is applicable to any type of container, that includes a screw threaded outlet neck, capable of receivingthe cap.

In Figures v1 to 4 inclusive I have illustrated one form of my invention which is applied to a 69; collapsible tube Ahaving a neck B which is provided with the usual screw threads arranged exteriorly thereo f., 1

g The capincludes a body in the form of a collar 1 that is provided with screw threads .on .5; the inner surface thereof for the purpose of receiving the screw threads of the neck, and

formed with the lower edge of the collarl is' an inturned flange 2' which is engageable with the lowermost thread of the neck in order to lpre- 70 vent the removal of the cap from the neck as will be apparent. f I

. Eigtendingoutwardly 'from the upper edgeof the collar is ahead 3 which may be serrated on the periphery thereof, but in any event provides 5 a grippingmeans for rotating the cap for a pur- 4 pose which will be presently apparent. .The top of. the cap is indicated by the reference numeral 4 and formed on and rising from the top and extending transversely thereof is a relatively 0 thick elongated reinforcing portion 5. Arranged laterallyof the elongated portion 5 is an outlet opening 6' which allows for thepassage of the contents .of the container, when the ,cap is moved from the positionas shown in. Figure 1, to the position as shown in Figure 4, or to any position between those mentioned, as it will be obvious that the contents of the container or tube as shown can be dispensed in accordance with the users desires.

Such a function is advantageous when use is made of a cap on a collapsible tubeof paste, as the cap can be moved whereby a thin or thick strip of paste can be dispensed.

The tube neck is provided with a valve seat '7 for the purpose of accommodating a valve member 8 formed with the underside of the top, and r it will be apparent that when the valve member is seated, an air-tight connection is provided between the cap and neck, with'the result that the contents of the tube or other container with which the cap is associated will be retained in the original, as'well as a clean and sanitary condition.

In Figure 5 I have illustrated a slightly modified form of my device, and in this form it will be noted that the valve member 9 of the cap 10 is conical shape and is adapted to be seated in a substantially conical shape bore formed in the top of the neck C of the tube D. The top of the v 1 invention will be readily apparent.

indicated by the reference numeral 15 and includes a rounded valve member 16 that is adaptedto be seated upon the edge of the bore of the neck F, and the cap 15 isprovided with an outlet opening in its top, which is disposed laterally of the elongated portion 17 in the same manner as in the other forms of the invention.

From the above description and'disclosure of the drawing, it will be obvious that I have pro-o vided a closure cap for containers that is held associated with respect to the container so as to prevent the caps frombeing lost therefrom or misplaced, and when use is'made of the cap with a collapsible tube as shown, it will be apparent that Whenit is desired to dispense the contents of the tube therefrom; the 'cap is rotated on the screw threads to move the valve members ofi of their seats, The tube is then pressed in the v usual manner to cause some of the contents to flow through the outlet the caps.

It is thought from the foregoing description that the advantages and novel features of my openings of the tops of I desire it to be understood that I may make changes in the construction and in the combina tion and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

WhatI claim is:

1. A closure cap for a container including a threaded neck, a threaded body for said cap and received by said neck, means to prevent the removal of the cap from the neck and being formed on said body, a top for said cap, a relatively thick elongated portioniormed on, rising from and extending transverselyof the cap to reinforce the same, said cap having an outlet opening arranged therein laterally of the elongated portion, and a valve member depending from said top below the elongated portion and engageable with the top of the neck to control the dispensing of the contents of the container through the outlet opening.

2. In a container having a threaded neck, a top for said neck and having a substantially conical shaped opening arranged centrally therein to provide a valve seat, a cap for said'container and threadedly secured to said neck, means to prevent the removal of the cap from the neck, a top for said cap, a relatively thick elongated portion formed on, rising from and extending transversely of the cap to reinforce the same,

,said cap being provided with an outlet opening laterally of the elongated portion, and a conical shaped valve member depending from the top of the-cap and having its pointed end receivable in the opening providing the valve seat whereby the valve member cooperates therewith to close the container as well as to control the dispensing of the contents thereof through the outlet opening. 1 I I 3. A combination with a collapsible tube having a cylindrical threaded portion with a circu-' lar orifice, of a closure cap therefor comprising: a threaded portion that co-acts with the said threaded portion or" the said collapsible tube, and an end wall, said end wall having an inwardly depending tapering portion arranged concentrically thereof and adapted to extend into said orifice when the cap is screwed down against the end of said tube, and by co-acting with the upper edge of said orifice form avalve, the said end wall being cut away on one side adjacent said depending portion so as to form an eccentrically located outletopening that is'closed by the upper'face of the said threaded portionof the collapsible tube when said valve portions are in their closed position.

4. A closure cap for collapsible tubes comprising a threaded portion for engaging the threaded cylindrical portion of a collapsible tube, and an end wall, a tapering portion depending inwardly and concentrically of the said end wall for entering into and forming a valve for the discharge orifice of the tube, the said end wall having a portion thereof cut away to form a discharge opening when the cap'is partially un-' screwed from the tube.
