DISPENSER FOR LIQUIDS AND PULVERULENT MATERIALS Filed May 24, 1951 INVENTOR.

atented Feb. 3, 1953 DISPENSER FOR LIQUIDS AND PULVERULENT MATERIALS David Brody, Clinton, Mass, as'signor to Van Brode Milling 00., Inc., Clinton, Mass., a corporation of Massachusetts Application May 24, 1951, Serial No. 228,035

1 Claim.

The present invention relates to improvements in dispensers for liquids and pulverulent materials of the type wherein the material to be dispensed is held within a closed, resilient and compressible receptacle, from which it is adapted to be sprayed or discharged in small, measured quantities by compressing or squeezing the receptacle.

Receptacles of the character mentioned are ordinarily in the form of bottles and serve to store toilet preparations, deodorants, disinfectants and the like. They are commonly made of plastic materials, preferably polyethylene. While for ordinary use the shape or design of the container is immaterial, its beauty or elegance is essential in case the container is to be placed on a dressing table or, as a matter of fact, into almost any room of the living quarters of a house. Squeezable polyethylene bottles do not lend themselves to relief ornamentation, as, for the purpose of obtaining the necessary degree of elasticity throughout the length of the bottle, it is essential that its cross-section at right angles to its longitudinal axis be uniform, and that its wall be thin and even throughout.

The main object of the present invention is to produce an ornamental dispenser of the type mentioned, which is composed of two sections, a decorated housing and a plain, squeezable receptacle, the former incasing the latter and cooperating with the same in dispensing the material contained in the receptacle.

Another object of the invention is to so construct the two elements of the dispenser that they are held together by friction only, that is without the use of special locking means or the like.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several elements and details of construction within the scope of the appended claim, without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of a dispenser constructed in accordance with the present invention;

Figure 2 is a section taken on line 2-2 of Fig. l;

Figure 3 is a top elevation of the improved dispenser;

Figure 4 is a front elevation of the receptacle element of the dispenser; and

Figure 5 is a section taken on line 5-5 of Fig. 4, on a larger scale.

In the drawings, the numeral l6 indicates the housing as a whole, and the numeral I l the receptacle as a whole. The housing comprises a base l2, from which rises an open casing l3 consisting of a front [4, along the entire perimeter of which is formed a continuous wall l5, extending at right angles to and rearwardly of said front. The housing may be made of any suitable rigid material, preferably a plastic substance. It may be ornamented in any suitable way. In the case illustrated in the drawings, the front wall is circular in configuration and the continuous wall, consequently, cylindrical, but it is obvious that the said front may be of any other configuration, for instance polygonal, in which case the wall l5 will be of prismatic design. In either case, the casing I3 is closed at its front and open at its rear.

For decorative ends, the front I5 of the casing, with the representations of fins l6, tail l1 and eye I8, presents a conventional fish, but it will be readily seen that any other suitable decorative scheme may be made use of, without departing from the invention.

In the top portion of the wall I5 is formed a recess l9, extending from the open end of the casing toward the front It thereof, but stopping short of the latter.

The receptacle II is, preferably, formed of polyethylene and comprises a front wall 20 and a rear wall 2|, the configurations of which correspond to that of the casing front l4, they being circular. These walls are connected by a wall 22, corresponding in configuration to that of the casing wall l5, it being cylindrical. On the wall 22 is formed a neck 23, fitting the recess IS in the casing wall 15. The neck is closed by a disk 24, provided with a minute discharge opening 25, around which is disposed, interiorly of the receptacle, a spray tube 26, which extends from said disk toward the bottom of the receptacle, stopping short of said bottom. The disk 24 is attached to the neck 23 and the tube 26 to the said disk in a manner so as to provide air-tight connections.

The thickness of the receptacle walls is held within limits to produce an easily squeezable and compressible structure.

From the rear wall 2| of the receptacle projects a flange 21, disposed in the plane of the said wall and serving as the means by which th receptacle is handled when it is to be inserted into the casing l3. To facilitate such insertion, the outer surface of the receptacle wall 22 is tapered toward the front wall thereof, the two circles A and B in Fig. 4 indicating the extent of the taper. If found necessary, the inner surface of the cylindrical casing wall I5 may be tapered accordingly.

After the receptacle has been filled with the desired liquid or pulverulent material to a height a substantial distance below its neck 23, to provide an airspace therein, the disk 24, with the tube 26 depending therefrom, is aflixed, for instance, by a suitable cement to the receptacle.

The filled receptacle is then inserted into the casing l3, it being forced through the open rear end of the latter, with the neck 23 in alignment with the recess IS in the casing wall [5, toward the front M of the casing. In forcing the receptacle into the casing, care must be taken so as not to compress the receptacle. The flange 21 on the receptacle serves as a handle, by means of which the receptacle may be grasped by the fingers of the operator in assembling the elements of the dispenser without the danger of squeezing the receptacle walls. The receptacle, due to the close fit between it and the casing, is held in the casing by friction.

For the purpose of the spraying the contents of the receptacle, the dispenser is taken hold of by one hand of the operator, the thumb of the hand being placed on the rear wall 22 of the receptacle and the remaining fingers on the front I4 of the casing, and the said rear wall forced 35 toward the front wall of the receptacle. The air within the receptacle is thereby compressed, escaping through the discharge opening 25 in the closure disk 24 and carrying with it and spraying or atomizing a small quantity of the receptacle contents. The receptacle returns to its normal form, as soon as the pressure is released thereon.

What I claim is:

A dispenser comprising a rigid housing including a base, a casing rising therefrom composed of a vertical front and a wall extending rearwardly from said front all around the perimeter of the latter, said wall having a recess at its top portion running from the open rear end of said casing toward said front, a closed, resilient compressible receptacle fitted into said casing from the rear thereof, said receptacle including a front side, a rear side and a wall connecting said sides, the configuration of said sides corresponding to that of the front of said casing and the outer face of said receptacle wall fitting closely the inner surface of said casing wall whereby said receptacle is retained by friction in said casing, a neck on the top region of said receptacle wall fitting the recess in said casing wall, a closure disk attached to said neck having a discharge opening, a spray tube fixed to said closure disk around its discharge opening extending therefrom toward the bottom of said receptacle but stopping short thereof, and a flange on the rear side of said receptacle arranged in the plane of said rear side and serving as the means whereby said receptacle may be grasped by the fingers of the user in assembling said receptacle with said housing,
