Mypresent invention-relates todispensers for products packaged in collapsible tubes havin outlet tips closed by caps threaded thereon.

Such tubes-are, iii-general, a convenientway of packaging various products of Whi'chtooth paste is perhaps the best example. The objectime to their use are that the caps' are'frequently'lostor are not replace'd with'theresult that .some of the contents deteriorate and is wasted,

that 1 when a tube-issque'ezed toflexpel its con- I tents, more than is needed is commonly discharged, and that the average user does not fully exhaust the contents oi-the tube before it is discarded.

Inaccordancewit-h myinvention, I- provi de a "dispenser'for products packaged in' suc'h collapsi- -ble tubes that consists of-a housinghav-ing -a, tube receiving chamber op'en'at one endand provided withmeans to exert-a collapsing pressure'on'a "tube in that chamber thereby to-'-expel its con- -tents through its threaded outlet tip. Connected to the housing adjacent the open end of 'the chamber is a support to which is attached a gate for-movement relative thereto between open 7 I provide a'member adapt- "ed to beconnected to the tipsof "the tube and that-member is heldby the-support to maintain it in operation relative to the gate. I prefer that the member be movable relativetoits support in "a direction transversely of the tube axis-so that the-tip may move along a'pathway under the influence of the tube collapsing means thereby to ensure that the tube contents maybe mores'come pletely exhausted than is'the case if the tube "tip is rigidly held. This is'also necessary to enable f different'size'd tubes to' be used'-efiiciently in the same dispenser and to ensure that' they "are properly positioned therein. 'For that reason, the

*aperture in the gate through which the tube-c0n tentsflow in the open position of the gate is in the form of' a slot sothat the'tip may register therewith in any of its positions. along its pathway.

In the drawings I have'shown an illustrative embodiment of my invention from which'these adispenser particularly adapted .for usewith toothpaste packaged in a collapsible tube lfl'having a'threa'ded outlet .tip Ii i The dispenser'shown in the .drawings'consists of 'a housing'lz having: an open-endedrchamber L3 and-a back wall M with "reference to which .thelhousing i2 .is so located that endtportions i5 and t6 'ofthe back wall are eXposed for-Jconvenience in attaching :the dispenserito any suitable supporting surface. The front portion I5 is preferablysoshapechas inclicatedtin Fig. 1, that it is I concealed by the detachable .closure,igenerally indicated'at I], for the open end of the chamber i3 andhasca singlezcountersunkhole 18 to ireceive an attachingscrew. The rearz'portion it Q isshown a's of substantial length andis divided by a horizontalrib Iii-spaced an equal distance from the top and bottom edges thereof and: ex-

I "provide the rib "[9 with: a 'plurality'o'f apertures 20 dimensioned 'to receive tooth brush handles "and 'on each side of it is a countersunk hole l3 for other attaching means.

Preferably, theJstem .23 is parallel to the 'The'dispenser may The attached to a 'suitable *supportingrsurface with the stem'23 .in an'u'pright or in 1a dependirg position" and it is proportioned "to be equallyrattractive and equally serviceabl "in 26-:towhich. a second annular shell, generally in- :either :position as may be desired bypreference or required "by the locationof the wash bowl, cabinetaor other fixtures.

, The closure consists of a firstiannularshell 24 secured atone end to the housing l2 as bye bayonet jointrindicatediathfi and ha'ving, at its other-end, aniinwardlydisposed annular flange dicated at 21, is secured by' bolts'28 having their heads'reoncealedbythefirst shell 24. The second :shell 21 "hasanroutlet port 29 and establishes a chamber 30 in'which :I mount an element 3| for .zmovementrelative thereto transversely of the outlet port129' and having an -aperturethreaded to 'receivezthetip II of "the tube I0. .I pivotally mount a gate 32 within the chamber 30 and hav- ;ingsanzactuatinghimr33extending through a slot the tip II is screwed into the element 3|.

34 in the periphery of the second shell 21 so that it may be moved from a first or closed position into a second or open position.

In practice, the second shell consists, as may be best seen in Fig. 2, of a disc 35, an end wall 33, and a ring 31 which constitutes a spacer so that the length of the chamber 30 is such as to accommodate the gate 32 and the element 3| for which the disc 35 constitutes a seat as it moves relative thereto and maintains it in contact with the gate 32. Preferably, the inner edges of the disc 35 and the flange 26 are beveled and dimensioned so that together they define a tapered port for the chamber 30 having its larger end disposed towards the chamber l3 and the outlet port 29 is oppositely tapered.

In the illustrative embodiment of my invention shown in the drawings, the gate 32 is pivotally supported as at 38 between the spacer 31 and the end wall 36 and the adjacent faces of the end wall 36 and the spacer 3'! are formed with complemental marginal shoulders 39 of sufficient length to define a major are so that on assembly, the peripheral slot 34 is established. The bolts 28 extend freely through the disc 35 and the shoulder 39 of the spacer 31 and are threaded into the shoulder 39 of the end wall 36. As such adjacent faces are similar, I have shown only that of the spacer 3'! which may be seen in Fig. 4.

As will be apparent from Fig. 4, the gate 32 in its closed position has its actuating arm 33 yieldably seated against one end of the slot 34 by the spring 49 attached at one end to the gate 32 and at its other end to the spacer 31.

As a dispenser in accordance with my invention is used, the tube collapsing means are actuated to exert pressure on the tube H) to expel its contents through its tip normally blocked by the gate 32. As the tube I is collapsed further, the tip l is free to move in the direction of the pressure applied to the tube since it is attached to the element 3| which is movable relative to the second shell. This ensures that the tube contents :may be much more completely exhausted. than would be the case if the tip were rigidly secured to the closure l8.

For that reason, the port 4| in the gate 32, which in the second position of the gate effects communication between the tube tip II and the outlet port 29, is in the form of a slot which registers in that second position with any position of the tip H as it moves along a pathway under the influence of the tube collapsing means.

In use, the closure I! is removed as a unit and The tube I0 is then inserted into the chamber l3 so that its end 42 is in parallel with the'pressure plate 2| and the closure I1 is replaced. Because of the fact that the element 3| is movable relative to the closure I1, the position of the tube willnot be affected by the attachment of the closure H to the housing l2 and this same fact ensures proper operation even if the tube H] is not inserted properly into the chamber I3. 'The handled stem 23 is then rotated to bring the pressure plate 2| into contact with the tube ID to exert sufiicient pressure thereon to cause some of its contents to be expelled when the gate 32 is moved by the user into its open position. While witha smaller tube it is necessary to rotate the stem "23 to a greater extent, its tip H is properly p0- sitioned because of the fact that the element 3| is movable relative to the closure l7.

Once a tube I0 is thus attached to a dispenser in accordance with my invention, it is only necessary for the user to move the gate 3| into its open position and the tube contents will flow out for his use until he releases the gate 3| so that it may be closed by the spring 40. With the tube collapsing means shown in the drawings, it is, of course, necessary for the user to turn the stem 23 from time to time to maintain pressure on the tube l0. When the tube I0 is emptied, the closure I1 is removed and the flattened tube H! is then detached from the element 3|. Before a new tube is attached, the closure may be rinsed in hot water to clean it.

From the foregoing, it will be apparent that dispensers in accordance with my invention are of simple construction and adapted to enable products packaged in collapsible tubes to be used with increased convenience and economy.

What I therefore claim and desire to secure by Letters Patent is:
