Fi l s st l u ther enlarge ,explod dn rsn nt e li he n v n cl ure me ns- I Referring to fl nvd awings in detail, the reference numeral '10 generally designatesla casing, which canjbe 0f n ld d'p n c r y other suitable.nie en a gsucha anon-corrosive metal. The casing is of vertieally elongated formation, and has vertical, :fiat side walls 12 414 respectively, a front wall 16 which can be fof 'sha 1y -sh pe s s ction as hown hons'hth srarncn on a o i n cr t c l t t e nten innh a t pfnc l 18, and an. open bottom.

Rigid with and projecting rearwandly and downwardly from thebackv wall of the casing is a, tonguezll, be of wedge shape, so asto ie ngagel in ,theppmplernentarily shaped guideway of a bracket 22 vhaving-iiiv'va ndly tu ne fl nges 2 defini l i .gnide y- 11 braeket 22iis attachable to a wall surfacenor the like, not shown, by means of vertically spaced screws 26'.,or[ e quiyalent fastening elements. i '7 V In the side wall- 12, there is formed a longitudinal slot 28, terminating at its upper end close to the top wall 18 and at its lower end close to the lower .entremityof the casing. The slot 28, at its lower end, may have ci eular enlargement 30, and extending through the "is he longitudinally slotted shank 32 of akey. having a, at, peripherally fluted or scallopedhandle 34, The per ular construction of the handle 34 facilitates the grasping and rotation of the key 32, it being. preferred as shown to form a handle of substantially large vdiameter;,f or -this Purp .Closing the .lower end of the casing is a loyten eud cap 36, having an upwardly directed peripheralflangfi receiving the lower end portion of the casing, ;T he casi n g cap 36 may be detachably securedhin'an. suitable ner .to the casing, and in thepresent instance .,is .to tightly and .frictionally.engage the easing thnoug 116 full periphery thereof. Cementedorotherwise to the inner surface ofthe cap a liner, 3 8. of 5 similar. material, bearing againstthellowjer, e d edgemf thejeasi'ng, and formed in the lineriis a ei-rcnlar ee nt er open n o subs an i l .diamet r- Anladapter has been generally designated at 42, and

. r 3 intermediate its ends is formed with a circular collar 48 fitting snugly and removably in the opening 40.

The adapter 42, above the collar, is formed with an elongated, axial extension 44, having external, threads for its full length, said extension being externally tapered fully from the collar to the upper extremity of the extension. Formed in the extension is an axial here through which the pasty contents of the supported toothpaste tube may flow, said bore continuing through the full length of the adapter, so as to open upon the lower end of a cylindrical, externally threaded body portion 50 of the adapter, said body portion extending .fully from the collar to the lower extremity of the adapter.

Removably connectable to the body'portion 50 is a cap member 52, the upper end portion of which is cylindrically shaped, and'the lower end portion of which tapers to the lower extremity of the cap member. In the upper end of the cap member there is formed a threaded recess 54 communicating at its inner end with an axial bore 56 of the cap member. The axial bore 56 extends fully to the lower end of the cap member, and is normally closed by a closure member 58 which, as shown in Fig. 3, has a spring hinge connection 60 to the cap member.

Diametrically opposite the spring hinge 60 is an outwardly projecting car 62 which canbe readily grasped by a user for a purpose of swinging the closure member 58 from its normally closed position to an open position shown in dotted lines in Fig. 3. In its open position, the closure member 58 depends substantially vertically from its hinge 60, and the spring of the hinge 60 is so tensioned as to normally swing the closure member to its closed position whenever the closure member is released following dispensing of the tube contents.

A conventional tooth paste tube has been designated at 64, and is disposed in inverted position within the casing. The key 32 is applied to the toothpaste tube with the base end of the tube extending into the slot of the key. It will thus be seen that to dispense the contents of the tube, one need merely rotate the key, so as to roll the tube from its base to its neck end, to effect dispensing of the contents.

In use of the device, with the casing cap 36 removed, the tube is inserted and the key applied in the manner previously described. Before insertion of the tube the closure cap, not shown, generally provided upon a tube of this type is removed, and the adapter 42 is forced into the neck of the toothpaste tube. The threads of the adapter are adapted to bite into the smooth inner surface of the cylindrical wall of the neck 66 of the tube, so as to connect the tube neck to the adapter in position such that the dispensed contents will be caused to flow through the axial bore 46.

It is of importance that the adapter is so designed as to be engageable in the necks of toothpaste tubes of different sizes. A small size tube will ordinarily have a relatively small diameter neck, whereas a large tube may have a neck of substantial diameter as shown, for example, in Fig. 4 in which the large size tube has been designated at 68 and has a large diameter neck 70. In this case, the adapter will extend to a further extent within the neck as may be noted by comparing Figs. 4 and 2. However, the same action is obtained, that is, when the adapter has been projected into the tube neck to the maximum extent, it can bite into the wall of the tube neck so as to securely attach the tube to the adapter. In effeet, a self-tapping or threading action is achieved, with the threads of the adapter forming thread grooves in the inner surface of the tube neck wall for a short distance.

With the tube supported in the dispenser casing in the manner shown, and the cap 36 applied to the lower end of the casing, the device is ready for use. A toothbrush 72 can be employed to swing the closure member 58 to open position, and will hold the closure member in the open position with the bristles of the toothbrush head 'dispos'ed'in position to receivethe flow out of the bore 4' 56 of the cap member 52. As soon as a suflicient amount of thetube contents has been dispensed, the closure member 58 will immediately swing back to its closed position under the force of its associated spring.

In Fig. 5 there is shown a slightly modified construction, making use of the same casing as shown in Fig. 1 and also making use of the same cap member 52. In this form, however, theadapter is omitted, and the neck of the toothpaste tube extends through the casing cap, which has been'designated at 74.

The casing cap is generally similar to the cap 36, except that it has a liner 76 which has a center opening 78 substantially greater than the center opening 40. Further, the cap 74 has a centrally disposed threaded opening 80, as distinguished from the smooth-walled center opening of the cap 36 of the first form.

In this form, the toothpaste tube can be threaded through opening 80, after which the cap member 52 is threaded directly onto the neck 66 of the toothpaste tube, with the adapter being eliminated.

In Figs. 7-10, there is shown another modification, making use of a slidable closure member instead of a hinged member such as has been shown in Fig. 1.

In this form the casing, casing cap 36, and adapter 42 are all identical to those used in the first form of the in vention. However, instead of the cap member 52 and closure member 58, there are used modified, analogous components including a cap member 82 having at its upper end an upwardly opening, threaded recess 84 communicating with an axial flow passage or bore 86.

As shown to particular advantage in Fig. 10, at its lower end the cap member has a reduced, axial extension 88 which is externally threaded. Further, formed in the lower extremity of the cap member 82 is a wide, deep transverse slot 90 of rectangular cross section, opening downwardly through the extension '88 and also opening upon diametrically opposite surfaces of the cap member. In depth, the slot 90 is greater than the length of the extension 88, that is, the inner wall of the slot is disposed above the juncture between the body part of the cap member 82 and the extension 88 thereof.

A slidable closure member 92 is formed as an elongated, flat, straight bar having at its opposite ends upwardly turned lips 94 to facilitate grasping of the closure member. Adjacent one of the lips 94 of the closure member 92 is an opening 96, adapted to be registered with the bore 86 when the closure member is slid to its dotted line position of Figs. 6 and 8. i

In assembling the cap member 82 and closure member 92, with a cap element 8 used for holding the closure member assembled with the cap member, one first shifts the closure member upwardly within the slot 90 to cause the closure member to bear against the inner wall of the slot. Then,- the cap element 98, which is tapered in extension of the taper of the cap member 82, is threaded onto the extension 88 so as to bear against the underside of the slidable closure 92 The cap element 98 (see Fig. 7) has an axial bore 100 opening upon the lower end thereof, and communicating at its upper end with a threaded counterbore 102 that engages the extension 88.

By reason of the arrangement illustrated, it will be seen that on assembly of the cap member with the closure member and cap element, the slidable closure is mounted for reciprocation in a direction longitudinally thereof between the full and dotted line positions shown in Figs. 6 and 8. In the full line position, the closure member is disposed to prevent flow through the bore 86 of the cap member, but to permit said flow one need merely shift the closure member to its flow-permitting position, with the toothbrush held under the cap element 98.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
