GAP FOR CONTAINEBSJ.

Application filed .luly 15, 1926. Serial No. 122,642.

\ This invention relates to caps for containers and particularly to improved caps for collapsible containers.

The object of the invention is to provide an improved easily and quickly operated cap for containers, the arrangement including a structure whereby the same may be openedand closed with the finger or thumb.

Another object of the invention is to provide a cap for containers suchas toothpaste containers, wherein means are presented which will hold a closure member 'releasably and resiliently in a closed position.

A further object, more specifically, is the arrangement of a cap for standard collapsible tubes having a standard cap, the invention including a closure plate for normally' closing an opening in the standard cap.

In the accompanying drawing- Figure 1 is a top plan view of a cap shown in an. open position disclosing an embodiment of the lnvention, the cap being illustrated on a container.

Figure 2 is a side view of the shown in Figure 1. t

Figure 3 is a view similar to Figure 2 but showing the cap closed and in section.

Figure 4 is a sectional view through Figure 3 on line 4-4, the same being on an enlarged scale.

Figure 5 is a view similar to Figure 3 but showing a modified construction of cap.

Figure 6 is a view similar to Figure 5 but showing a further modifiedform of cap.

Figure 7 is a view similar to Figure 1 but showing another .form of the invention.

Figure 8 is a view similar to Figure 3 but showing the form of the invention illustrated in Figure 7.

Referring 'to the accompanying drawing by numerals, 1 indicates a collapsible tube which may contain soap, tooth paste, petroleum jelly or other asty or semi-liquid substance which may be ejected by collapsing the tube. The discharge end of the tube is provided with a threaded neck 2 receiving a cap 3 which is of usual construction heretofore made except that it isprovided with a passage-way 4 in the top. I This cap is adapted to clamp an encircling section 5 of the spring 6 against the body of the tube 1 for holding the same in proper position. Spring 6 merges into a supporting plate 7 which is provided with a turned Over section structure barrels 8. The plate 7 is provi ed with a cut and bent section 13 formin an interlooking member or'projection wit a. resilient extension 14. Th1s extension is provided with an offset ortion 15 extending partly around the section 13 and with an extension 16 presenting a hand hold for manipulating the cover or cap 10. This cover or 'cap is provided with a pressed up ortion 17 presentinga hole or cavity in w ich a packing member 18 is placed, said packing member being of any suitable material, as for. instance, cork. The packing or cork 18 is adapted to press against the upstanding bead or projection 19 formed on the cap 3 around the passage-way 4. By reason of the resilient action of members 14 and spring'6, the cork 18 is pressed tightly against member 19 and in fact, member 19 is slightly embedded in cork 18.

This presents a very desirable structure which may be readily opened by pressing upwardly on the extension 16 whereupon spring 6'will function to quickly'move the parts to the position shown in Figure 2. When the closure or cap 10 is closed, the same is merely swung over to substantiallytheposition shown in Figure 3 and is then pressed downwardly until it assumes this position. When the parts are in a closed or locked position as shown in Figure 3, spring 6 continually acts to'pull downwardly on the-knuckles 8 and, consequently, pull downwardly 0n the packing 18. This results in keeping the tube 1 sealed while presenting continually, means which I may be operated by one hand for releasing the closure and again latching the same.

In actual operation, usual y the tube 1 is grasped by one hand and the thumb of that .hand used to ress upwardly on the exten-' sion 16 where y the parts are released and caused to uickly inove over to the position shown in I igure 2. After the tube has been squeezed to the desired extent, the thumb of the hand which holds the tube moves the parts again to their closed position as shown in Figure 3.

In Figure 5, a modified form of the invention is disclosed which is similar to Figure 1, except that the cover or plate 10 s provided with a depressed portion 20 which is adapted to snugly fit into the passage-way ,4 of the cap 3 whereby this passage-way is tightl sealed.

ispresented wherein the closure plate is made flat and is adapted to press flatwise against the flange or bead 19 whereby a reasonably ti ht closing action is presented. Aside from t eparts especially referred to, the structures in Figures 5 and 6 are identical with that shown in Figures 1 to 3.

In Figures 7 and 8 another form of the invention is shown wherein the plate 10 merges into a cup 20 pressed so as to be capable of fitting over the tubular member or cap 3. However, a gasketor washer 21 is arrangedin the cup 20 as shown in Figure 8 so that when the parts are closed the cup will become even with or slightly telescoped over the upper end of the cap or tubular member 3. Aside from this slight difference, the structure is identical with that shown in Figures 1 and 3 and an additional description will, therefore, not be given.

What I claim is:

1. A closure structure for a collapsible tube formed with a threaded outlet member, comprising a tubular threaded member screwed onto said threaded outlet member,

said tubular threadedmember having a discharge opening registerlngwith the openin in said outlet member and an annular bea surrounding said discharge' opening, a'

spring provided with a supporting plate, said spring surrounding said outlet member below said tubular member, a closure plate carried by said supporting late, said supporting plate surrounding said tubular member normally held by said spring against said annular bead, said closure late being formedwith a depression, a pac ing mem ber arranged in said depression and engaging said bead when the closure late is in a closed position, means carrie by said spring acting as a catch for normally holding the closure plate in a closed position, said spring normally tending to quickly move the closure plate to an open position when said catch is released.

2. A ca comprising a closure plate formed wit a depression presenting a cavity, means acting as a gasket fitted into said cavity, a member formed with a portion adapted to encircle the neck of a container and a supporting late,'the neck encircling said supporting plate, said closure plate" be ing formed with an extension, and a catch carried by said resilient portion adapted to interlock with said extension for nor mally, holdin the closure plate in a closed position, sai spring functioning to move said supporting plate and cause saidclosure plate to swing to an open position when said catch is released. I

. 3. A cap for a container comprising a In igure 6, another form of the inventionclosure plate formed with a depression and a pressed out portion presenting a knob, a

member formed with a portion adapted to encircle the neck of a container and a supporting plate, the neck encircling portion and plate being connected by a resilient portion acting 'as a spring, a catch carried bysaid resilient portion adapted to interlock with said knob for normally holding said closure plate in a closed position, and means for hingedly being positioned to swing said supporting plate to a given positlonwhen said catch is released, said closure plate being swung toan open position by the supporting plate when the supporting plate has been swung to said given position.

, nnecting said? supporting plate and the closure plate, said member 4. In combination with a container having a neck formed with a discharge opening extending therethrough, a closure plate for.

said opening, said closure plate being formed with a depressed portion presenting a cavity, means acting as a gasket fitted into said cavity, a member formed with a supporting plate having an opening through which the neck projects, a portion encircling the neck, and a, looped portion connecting the plate and neck encircling portion and forming a spring-means for hingedly connecting said closure plate with said supporting plate, and a catch carried by said looped portion for normally holding said closure plate in a closed position, said spring portion when hinge knuckles, a closure plate formed with' means interlocking with said hinge knuckles for hingedly connecting the closure plate with the suporting plate, said closure plate being also ormedwith an extension having a pressed out knob co-acting with said rolled portion for forming a catch structure for normally holding said closure platein. a closed position. r

6. The combination with a container formed with a threaded discharge having an opening extending therethroagh,

of a tubular member having a discharge opening in line with the opening n the Lac threaded discharge member, said tubular member being screwed onto said threaded discharge member, a closure plate ior closing the discharge opening in said tubular member, an extension projecting from said closure plate,- means carried by the container for hingedly supporting said closure .plate, said means being formed with a catch coacting with said extension for normally holding t e closure member in a closed position, sald means being also formed with a spring portion surrounding said threaded discharge member, said spring portion acting to cause said closure member to swing to an open position when said catch is released.
