Application August 5, 1942, Serial No. 453,637

(Cl. 20G- 42) 13 Claims.

This invention relates to dispensing containers.

vMore particularly the invention is directed to a container of the type which segregates a predetermined quantity of material while ythe container is .closed and, upon movement of the cover, exposes the segregated material for distribution without exposing the remaining material in the container.

One of the objects of my invention is to provide a dispensing container of the character described which shall be simple and economical to manufacture.

Another object of my invention is to provide a dispensing container of the character described which comprises relatively few and simple parts, which is rugged in construction and which can be readily fabricated from inexpensive non-metallic materials such as plastics.

Another object of my invention is to provide a plastic dispensing container of the character described which shall comprise but three parts, a container body, a cover, and means for biasing the cover to closed position, and in which the container body and cover are so shaped and dimensioned that they can be molded to substantially vnished form in simple two part molds.

Another object of my invention is ,to provide a plastic dispensing container of the character described in which the three parts comprising the container can be assembled simply by manipulation and without requiring additional parts or additional forming operations.

Another object of my invention is to provide a plastic dispensing container of the character described whose cross-sectional area diminishes from top to bottom whereby filling of the container and stripping from a mold is facilitated.

Another object of my invention is to provide a dispensing container of the character described in which the mouth is of greater cross-sectional area than the rest of the container body and in which the dispensing compartment :which receives the segregated material extends outwardly away from the main compartment, but is so supported and arranged that it is laterally concealed and cannot easily be damaged.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplied in the construction hereinafter described, and of which the scope of application will be indicated in the claims.

In the accompanying drawing, in which is shown one of the various possible embodiments of this invention,

Fig. 1 is a vertical central longitudinal section through a container embodying my invention;

Fig. 2 is a front view thereof;

Fig. 3 is a top View with the cover displaced so as to expose the dispensing compartment;

Fig. 4 is a sectional view taken substantially along the plane indicated by the line 4 4 in Fig. 1;

Fig, 5 is a top View of the container body with the cover removed; and

Fig. 6 is a bottom View of the cover.

Referring now to the drawing, I6 denotes a dispensing container constructed in accordance with my invention. Said dispensing container comprises a container body or receptacle I2, a cover I4, and a narrow leaf spring IE for biasing the cover to closed position. Both the container I2 and cover I4 are molded from a suitable plastic material such, for example, as a phenolic, urea, vinyl, vinylidene, acrylic, styrene, polyterpene hydrocarbon, or melamine resin, a cellulose ester, a cellulose ether, or a protein plastic.

The .container body I2 comprises a large main compartment I'I defined Kby a bottom wall I 8, two

side walls

20, 22, and front and

back walls

24, 26. The two

side walls

20, 22, and the front and

back walls

24, 26 are substantially parallel but flare slightly and uniformly toward the mouth 28 of the main compartment I 'I to facilitate stripping of the container body I2 from a mold and filling thereof with a dispensable product. The two

side Y walls

24, 26 are substantially vertical and straight (see Fig, 4) but the front and

back walls

24, 26 are curved about a common center (see Fig. l) in order to set back the mouth 28 of the main compartment from the forrward edge of the bottom wall I8 for a purpose which will soon be apparent. It will be appreciated that by using substantially the same center of curvature for the front and

back walls

24, 26, the container body l2 can be stripped from curved molds.

Lying forwardly of the top of the front wall 24 is a dispensing compartment 3l! which is of such size and shape that when closed of it will accommodate a desired predetermined quantity of material or number of tablets T. To simplify the construction and molding of the cover I4 and the container body I2, the

mouths

28, 32 of both the main and dispensing compartments may be disposed in the same horizontal plane. The rear of said dispensing compartment 3U comprises a part of the front wall 24 of the main compartment. The tip 34 of the dispensing compartment extends forwardly from said wall 24 a distance substantially equal to the distance that the top of said front wall is set back, so that said tip is substantially vertically aligned with the front edge of the bottom wall I8 (see Fig. 1).

In order to support, reinforce, and protect the jutting dispensing compartment 30, roughly triangular parallel

planar extensions

38, 40 are formed on the

side walls

20, 22 forwardly of the front wall 24 and laterally of said dispensing compartment. Said

extensions

38, 40 run out almost to said tip 34 and merge at their upper sides into the walls of the dispensing compartment (see Fig. 3). 'I'hese extensions may be slightly thicker (Fig. 2) than the

side walls

20, 22 of the main compartment (Fig. 4) to enhance the appearance of the dispensing container. The walls of the dispensing compartment 30 are all ared toward the mouth 32 thereof and are otherwise so shaped that they may be stripped from the curved molds on which the container body I2 is formed.

During molding, the

side walls

20, 22 are provided with a pair of

parallel rails

42, 44 projecting from their top edges and extending for substantially less than the length of said walls. Said rails are disposed adjacent the inner surface of the container body I2, and, subsequent to molding, are undercut to provide shallow grooves 45 along the outwardly facing surfaces thereof.

The cover I4 has a plan contour (Fig. 6) substantially the same as that of the container body I2 (including the dispensing compartment 30) and is cupped to permit transfer of material from the main to the dispensing compartment when the container is closed.

The two

side walls

46, 48 of the cover are provided during molding with two parallel

thin portions

50, 52 which serve as cover guide rails and are disposed adjacent the outer surface of the cover so that they are spaced apart slightly more than the

body rails

42, 44. Said cover rails are undercut along the inwardly facing surfaces thereof to provide shallow grooves 54. The container body and

cover grooves

45, 54 are so dimensioned that when the body and

cover guide rails

42, 44, 50, 52 are laterally juxtaposed the cover I4 will be slidably locked on the container I2. The length of the

cover guide rails

50, 52 is greater than the length of the

body guide rails

42, 44 by an amount substantially equal to the length of the dispensing compartment 30 in the direction of movement of the cover. Due to this construction, the ends of the heavier portions of the

cover side walls

46, 48, where the

rails

50, 52 terminate, serve as stops in conjunction with the ends of the container

body guide rails

42, 44 to limit reciprocation of the cover I4 relative to the container body I2. Said cover and body guide rails are so arranged that at one extreme position of the cover (Fig. 3) the dispensing compartment will be fully exposed, but the interior of the main compartment I'I will still be covered, and at the other extreme position (Fig. 1) of the cover both dispensing and main compartments will be covered.

If desired, serrations 56 may be formed in the top of the cover to facilitate manipulation thereof.

The spring I6, which biases the cover to the closed position (Fig. 1) has its forward end resting in a niche 58 in the cover, and its rear end resting on a ledge 60 in the container body. The niche 58 may be cut in the cover subsequent to molding.

In accordance with an ancillary feature of the invention the dispensing compartment 3|) is made only long enough to receive one tablet, and the portion 62 of the spring over said dispensing compartment cooperates with the rear wall and mouth of said compartment to define a passageway 64 which is only long enough and deep enough to allow one tablet at a time to pass therethrough. With such construction, after the container is inverted to charge the dispensing compartment and then righted, the single tablet lying in the passageway 64 will drop into the dispensing compartment and leave the passageway clear. This prevents mutilation or breakage of tablets by the cover when it is slid back to expose the dispensing compartment. It will be understood, of course, that the width of the compartment 30 and passageway 64 may be increased to accommodate two or more tablets without departing from the spirit of this feature of the invention.

It will be observed that the

side walls

20, 22, 46, 48 of the container` body and cover are relatively thin, which, since they are made out of a plastic material, makes them somewhat resilient and enables them to be manually deformed. Because of this construction the cover and container can be assembled with ease, without using tools or extra parts, and without having to deform the cover or container body after assembly to hold container parts together. The assembly of the cover and container is carried out by setting the rear end of the spring I6 on the ledge 60 and the forward end of said spring in the niche 58 while the cover and container body are held in closely spaced relationship. Opposed fingers of one hand then squeeze the

side walls

20, 22 of the container body together thereby springing the

body guide rails

42, 44 inwards. Simultaneously, the front and back of the cover are squeezed together thereby outwardly bowing the

side walls

46, 48 of the cover and spreading the cover guide rails 5U, 52 apart. These combined movements of the cover and container body guide rails suffice to allow the cover to be slipped over the container body with the lower portion of the cover guide rails horizontally aligned with the under-cut grooves 45 in the body guide rails. 'I'he cover and container body can then be released, whereupon they will resume their normal shape with the guide rails interlocked as shown in Figures 1, 3, and 4.

It will thus be seen that there is provided a device in which the several objects of this nvention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
