Patented Aug. 26, 1952 PUMP TYPE DISPENSER WITH CARTRIDGE HAVINGFLEXIBLE AND RIGID PORTIONS Joseph R. Harrison, J r., Qliicago, Application March 31, 1947, Serial No. 738,288

My invention relates, generally, to dispensing means, and it has particular relation to dispensers for tooth paste, shaving cream and like material.

Among the objects of my invention are: to provide a holder for a renewable cartridge or refill unit containing the material to be dispensed; to employ air pressure developed by squeezing a part of the holder for ejecting the material from the cartridge; to employ a self restoring rubber bulb as a part ofthe holder and to provide avalve therein for trapping air between the same and the cartridge; to provide the cartridge with .a rigid tubular section and a member that is movable therethrough on application of air pressure thereto for ejecting the material; to form the movable member of flexible material having a length about equal to that of the rigid tubular section; to reinforce the movable member of flex ible material; and to employ a plunger within the rigid tubular. section forejecting the material therefrom.

With the foregoing objects outlined and with other objects in" view which will appear as the description proceeds, my invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Fig. l is a view, in side elevation, of a dispenser constructed in accordance with my invention;

Fig. 2 is a bottomplan view of the dispenser;

Fig. 3 is a longitudinal sectional view of the dispenser, showing one form of cartridge or refill unit in the holder;

Fig. 4 is a longitudinal sectional view of the cartridge when it has been emptied;

Fig. 5 is a view, partly in side elevation, and partly in section, of a modified form of cartridge; Figs. 6 and 7 show modified forms of cartridge in which different reinforcing means for the flexible member thereof are provided; and

Fig. 8 is a detail sectional view, at an enlarged scale, of the air valve for the bulb of the holder.

Referring now to Figs. 1, 2 and 3 of the drawings, the reference character In designates, generally, a dispenser which includes a reusable holder that is indicated, generally, at H. As indicated, the holder l I is intended to be reused and to contain a cartridge or refill unit, to be described in detail hereinafter, which containsthe material, such as tooth paste, shaving cream, etc. to be dispensed in small quantities.

The holder ll may have at its upper end a large threaded cap I2, preferably of metal, which 11 Claims. (01. 222-) is removed to permit insertion of the cartridge. The cap [2 has a smaller threaded cap l3, of. plastic or like material, which can be removedto permit ejection of the material from the cartridge and then replaced. The holder I l includes a rigid tubular shell I4 of metal or plastic to the lowerv end of which a deformable member or bulb, I5 of rubber or the like may be secured by any suitable means, such as the ribs It. The bulb l5 can be squeezed by the hand to generate airpressure Within the holder I l.

The bulb l5 has an integrally formed suction cup H at its lower end which, when depressed againsta flat surface, serves to create a vacuum and thereby to hold the dispenser H3 in an upright position relative to the flat surface.

At its lowerend, the bulb l5.has an integrally formed flange 18 in which a valve mechanism, shown generally at 19, is located, and illustrated more clearly in Fig. 8. The valve mechanism 19 includes a valve stem 2:] that projects through the flange [8 and has a radial foot portion 2| which, together with a retaining ring 22, serves Within the holder H is a cartridge or refill unit that is indicated, generally, at 30 in Figs. 3

and 4. It will be understood that it is suitable for holding cream-like, or jelly-like material that is to be dispensed in small quantities. It includes a rigid tubular member 3| that may be formed of metal, cardboard, lastic or the like, and which may have an out-turned flange 32 which bears against the upper end of the shell I4. A closure member 33 in the form of an annular disc is secured, as byadhesive, to the flange 32 for closing th'e'upper end of the tubular member 3|. The closure member 33 has an aperture 34 whichregisters with an aperture 35 in the cap I2, through which the material is ejected when the cap [3 is removed. The closure member 33 preferablyhas a removable cover secured thereto for shipping and storing purposes which can be stripped off.

easily when the cartridge 30 is inserted in the holder H.

At its lower end, the tubular member 3| has a flexible member 36 secured thereto. It may overlap the member 3|, as shown at 3'l, and may be. formed of suitable material such as Water-proofed cloth or like fabric, or polythene 0r acetate plastic sheeting or cellophane. When the cartridge or refi11 unit 30 is first placed in the holder l l, the flexible member 36, the length of which is about equal to that of the tubular member 3|, extends full length into the bulb l5, as shown in Fig. 3. When the bulb I is squeezed, the pressure of the air between it and the cartridge is increased. Since only the member 36 is deformable, the air pressure applied to it causes the same to collapse and then, on repeatedsqueezings of the bulb l5, to assume the shape shown in Fig. 4. In so do ing, the material within the cartridge 30 is dispensed through the aperture in the cap I2,

A gasket 38, of soft rubber or the like, may be positioned underneath the cap 12 for providing an air-tight seal with the shell l4.

In Fig. 5, an alternate form of cartridge is shown, generally at 40. sleeve 4| of metal, paper, plastic or th like,

.4 in th collapsible bulb has an air valve operable on release of pressure from the former to admit air to fill the space previously occupied by the ejected material.

3. The invention, as set forth in claim 2, wherein the bulb is formed of self restoring resilient material whereby afte it has been squeezed and released it restores itself to its initial form.

' 4.-Theinverition, as setffor'thlin cl'aim 3, wherein the bulb "has a suction "cup integrally formed therewith which serves to hold the dispenser in It may-comprise a rigid which can be inserted in, the holder II when its cap I2 is removed. It may extend nearly to the lower end ofth'e bulb l5, and at its upper end it may have a flange 42 for abutting the upper erid' of the'she'll I4, and to which may be securedan annular closure member 43. t th lower end of the Sleeve "4!, there is positioned, when the cartridge '40 :is full, a plunger '44 that is gradually driven'to the upper end by the repeated application of air pressure thereto.

-An0ther form of cartridge is shown generally at 30' in Fig. 6. It is essentially of the same construction as illustrated in Figs.- 3 and 4., with the addition of reinforcing means in the form of oppesite1y spirally wound strips 41 and 48 of rela-' tively rigid material such as card board, fish paper" or the like. These stri s serve to reduce th likelihood of rupture of the flexible member 36', and collapse therewith on application of air ressurethereto as described.

Anotl'ier cartridge construction is shown at 30" in Fig. '1. Itis sim'iiar to the cartrid e so, but for reinforcing means, there may be provided a sleeve 50 of rigid material, such as card boardor fish paper, which telescopes with the rigid tubular member 3| as the flexible member 35 is collapsed. 'Like the strips '4'! and 48, the sleeve 50' serves to reduce the likelihood of the flexible member 36 being ruptured on application of air pressure thereto;

} While I have disclosed what I consider tobe preferred embodiments of my invention in such manner that the same may be readily understood by those skilled in the art, I am aware that changes may be made in the details disclosed, without departing from the'spirit of the "inven-= tion, as expressed in the following claims.

' What I claim and desire to secure by Letters Fatentis: e V g A dispenser fo'r toothpaste, shaving'cr'eam and like'material, comprising, in combination; a
