JACOB EGKAR'I, OF FURTH, IBAVARIA, GERMANY.

CONTAINER.

Application filed February 2, 1927, Serial No. 165,485, and in Germany February 9, 1926.

The invention generally relates to containers and more particularly to that class of containers in which are provided two chambers or compartments each adapted to contain an ingredient or ingredients of a product, thus enclosing the whole of such prodnot while keeping the ingredients. separated until ready for use.

In the preparation of paints for the market, for example, such containers are particularly desirable because many paints, especially bronze, aluminum and like metallic paints, if kept ready mixed for a length of time are apt to fade and deteriorate.

It is therefore the object of the invention toprovide a simple and economically constructed container in which is provided a main receptacle body and a partition member dividing that body into an upper chamber for holding the bronze, aluminum or other metallic powder, and a lower chamber for holding the varnish or other liquid vehicle, the two ingredients being thus kept separated during the shelf or storage period. Further, the partition member has a knockout portion and a cover is rovided for the body which cover carries a nook-out plunger or pin the upper end of which extends through the top of the cover and the lower end extends down through the upper chamber into close proximity to the knock-out portion of the partition member so that s when it is desired to use the paint it is only necessary to smartly strike the plunger to force its end into forceful contact with the knock-out portion to dislodge the same and open communication between the upper and lower chambers and permit proper mixing of the paint ingredients, this operation being possible without removal of the cover.

With the above and other objects in view that will hereinafter appear, the invention further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully de- In carrying out the invention, according to one practical arrangement, the container comprises an outer or main receptacle body closed at its bottom in the usual manner and having a top flange 2 over which is mounted the flange 3 of the cup-like partition member 4 the walls 5 of which may be slightly tapered to be smaller at the bottom than at the top. The member 4 is open at its bottom as at 6, the opening being closed by a knock-out bottom 7 having a flange 8 to snugly fit within the opening 6 and normally form a hermetic seal separating the body 1 into an upper powder chamber 9 and a lower varnish vehicle chamber 10.

A lid or cover 11 serves to close the container at its top and the said cover is provided with an opening 12 in which is secured a friction sleeve 13. A knock-out plunger or pin 14 is carried by the sleeve 13, the head extending above the sleeve and .its lower end extending below the sleeve into close proximity to the knock-out partition or bottom 7. To augment frictional contact of the pin 14 in the sleeve 13 the said pin may be provided with a ribbed portion 16 for contacting with the sleeve.

It will be observed that the cover 11 is dished or provided with a central depression. Thus when the pin 14 is in its normal position its head 15 remains below the limits of said top and thus normal stacking of the containers in storage or shipment is'notv interferred with and the possibility of inadvertent actuation of the plunger is rendered remote.

The container, of course, may be constructed in any manner conventional in the related art and I do not wish to be limited to the precise construction illustrated in Figures 1 and 2 of the drawing, as the construction may be varied within the scope of the appended-claims. For example, in Figure 3 of the drawing, I have shown a modified flange construction which may be employed if desired. In this figure, I have also shown the pin .14 equipped with a spiral-ribbed portion 16. In this form the sleeve may be either smooth-bored or grooved as may be desired to add to the frictional mounting of the plunger therein.

When the paint is required for use, the

plunger is smartlystruck 1n a downward direction, and such operation forces the bottom or knock-out portion 7, constituting the floor of the upper compartment 9, down into the lower compartment 10, allowing the powder contained in the upper compartment to fall into the liquid vehicle 1n said lower compartment. This operation is performed with the cover 11 still in position and on removing the cover the mixed paint is accessible for use.

By tapering the walls 5 of the partition member, means is not only provided for facilitating the mounting of the bottom 7, but also a drip and brush wiping edge is provided surrounding the opening 6. Also an air space is provided surrounding the lower end of the partition member which allows expansion of the contents of the lower compartment without tendency to force the bottom 7 upwardly which might flush with t e top edge of the cover.

result in'leakage from the upper compartment.

By positioning the plunger head 15 in the cover depression means is not only provided to prevent inadvertent actuation of the plunger but also for indicating to the buy mg public that the container is intact and the partition member unbroken. When in its normal osition the plunger bead top is Thus, by noticing the position of the plunger head, a buyer can always assure himself that the plunger is in its normal position.

From the foregoing description, taken in connection with the accompanyin drawing, it is thought the novel details 0 construction, the manner of use of the invention and the advantages thereof will be readily apparent to those familiar with the art to which it relates.

What I claim is:

A container of the class described comprismgl a receptacle body, a cover for the body aving a central depression, a partition adapted to separate the body into an upper and a lower compartment and including a knock-out portion, and a plunger PIO]8CtBd through and carried by the cover and having a striking head located within and operable in the depression of the cover and'a knock-out portion dislodging end projected into close proximity with said knockout portion.

2. 'A container of the class described comprising a receptacle body, a cover for the ody having a central depression, a partition adapte to separate the body into an upper and a lower compartment and in c uding a knock-out portion, a lunger pro- 'ected through and carried by the cover and aving a striking head operable in the depression of the cover and a knock-out portion dislodging end projected -into close proximity w1th said knock-out portion, and a sleeve carried by the cover through which the plunger projects and in which it is held in tight frictional engagement, said plunger being of a length that when the bottom of the plunger is in contact with said knock-out portion the head of' said plunger will lie wholly within said central depression of the cover.

3. A container of the class described comprising a receptacle body, a cover for the body having a central depression, a partition adapted to separate the body into an upper and a lower compartment and includ-',

ing a knock-out portion, a plunger projected through and carried by the cover and having a striking head operable in. the depression of the cover and a knock-out portion dislodging end projected into close proximity with said knock-out portion, a sleeve carried by the cover through which the plunger projects and in which it is held in tight frictional engagement, said plunger having a ribbed portion. adapted to, engage in the sleeve to augment such frictional engagement, said plunger being of a length that when the ,bottom of the plunger is in contact with said knock-out portion the head of said plunger will lie wholly within said central depression of the cover.
