FREDERICK L. SLEEPER, OF CHICAGO, ILLINOIS.

CERAMIC-PAINT PACKAGE.

To all whom fit may concern:

Be it known that I, FREDERICK L. SLEEPER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ceramic Paint Packages, of which the following is a specilication.

This invention relates to improvements in ceramic paint packages and refers more spe-A citically to improvements in ceramic paint packages, the salient object of the invention being to provide a package in which the paint is kept hermetically sealed and in perfect condition, yet sealed in such manner that when opened the contents of the package are kept entirelyfree from contamination of the sealing materialh and sealing devices and are accessible with the greatest convenience and without loss by waste.

Other objects of the invention are to provide a form of package which eliminates expensive slow assembling by hand and secures great certainty of effective sealing; to provide a form of package which exposes the contents to View through a transparency and be manufactured and assembled with enhanced economy; to provide a package of such construction that the act of opening it provides a hinged cover which may afterward be closed to guard the remaining contents of the package; to provide a package which is extremely neat and tasty in appearance, showing at a glance that it may be used in a cleanly manner and without waste due to smearing the contents over waste surface or losing any part thereof by transferring the paint from one side of the base to another.

Other advantages and improvements will appear to those skilled in this art.

The invention consists in the matters hereinafter described and more particularly pointed out in the appended claims.

In the drawings Figure 1 is al transverse sectional detail of my improved package, the section being taken through the central portion of Fig. 3 and the crimping flange of one member of the box being left uncrimped, although the parts are otherwise assembled. Fig. 2 is a view like Fig. 1 but with the crimped flanges closed down into nal position. Fig. 3 is a plan view of the package. Fig. 4 is a perspective view of the package with the cover portion cut loose and opened up.

Specification of Letters Patent.

Application filed June 6, 1911.

Patented Nov. 21, 1911. Serial No. 631,530.

Broadly speaking, packages of this type are not new. Heretofore, athe quantum of paint has been applied to the central portion of a glass or vitreous slip and the same covered by a Celluloid cover having its edges cemented to the upper surface of the slip around the edges of the paint, and having the celluloid cover made convex so as to remain out of contact with the paint. In using such a package the edges of the celluloid are cut or broken away from the cement and lifted off, after which'it is the custom and is practically necessary to transfer the paint to the opposite side of the slip, in order to avoid its contamination by the cement materials adhering to the glass. This is inconvenient and accompanied by a loss of paint.

The advantages of the present improvement will appear from the description of the package.

Referring to the drawing, 1 designates a partly-formed metal box (preferably aluminum), which is by means of a suitable die formed into a shallow box portion-proper Q. surrounded by an outstanding horizontal flange 3, the upper surface of which is about flush with the top side of a glass slip 4, fitted loosely within said package. An extension portion 3 is formed integral with the flange portion 3. As blank 1 leaves the factory ready for assembling, flanges 3 are perpendicular to the main plane of the box.

The cover, 5, which is preferably transparent celluloid is cut of a size to lit easily inside the upstanding flanges 3 and has its central portion 5 made sufficiently convex so as to remain out of contact with the body of paint 6 which is applied to the central portion of the glass slip 4. The slip 4, bearing its charge of paint, is dropped into the shallow box, the celluloid cover then being placed in position within the blank and thereafter, by means of a suitable die or tool the upstanding flanges 3 are crimped over inwardly into firm bearing with the edges of the Celluloid, thus forming to all practical intents, a hermetically sealed or closed package.

The body of the box is purposely made vslightly larger in its internal dimensions than the sli of glass, as indicated by the dotted lines? and 8 in Fig. 3, the outer line indicating the inner planes of the vertical walls of the box and inner dotted lines the outer' edges of the slip. When the box is to be opened, the operator with a suitable knife point cuts through the celluloid cover between the dotted lines along three sides of the boX and then lifts up the Celluloid, While the uncut fourth side of the latter acts as a hinge. This aifords complete access to the paint upon the slip without removing it from the box, or, if preferred, the slip can be lifted out of the package and afterward returned. In either event, the paint need not be smeared .over 4the face of the slip more than is necessary in taking it up with a spatula or other suitable tool and there is obviously no chance for the paint to become contaminated from any part of the inclosing package.

Inasmuch as the paint put up in this form is usually gold and therefore of very high value, it follows that the elimination of waste together with preservation against contamination become matters of unusual importance.

Thile I have herein illustrated and described the preferred embodiments of my invention, it is to be understood that the arrangement -of the details and construction may be modified within certain limits without departure from the invention.

I claim as my invention:

l. A paint package comprising a plate of vitreous material, the central portion of which is adapted to receive a charge of paint,

a pair of members for ent-irely inclosing said plate, one of said members being transparent, and the other of said members being recessed to receive the plate and the marginal edges of one of said members being crimped over the marginal edges of the other member to form a hermetically sealed joint.

2. A paint package comprising a slip of t vitreous material for receiving a charge of paint at its central portion, a sheet metal shallow cup-like inclosing member adapted to receive said slip and provided with marginal crimping flanges andan impervious member over-lying said slip, having its central portion made convex to remain out of contact with the paint and having its margins hermetically engaged with crimping iianges of the opposite member.

3. A paint package comprising a glass slip, for holding a charge of paint at its central portion, a sheet metal shallow cup-like receptacle shaped to conform to and receive said slip and provided with outstanding marginal iianges, each iiange folded back upon itself, and a transparent Celluloid cover overlying the slip, having its central portion conveXed and having its margins inserted and embraced within the said flanges.
