Oct. 15, 1968 s. D. COLLIE ARTICLE PACKAGE CONVERTIBLE TO A CONTAINER Filed Nov. 4, 1966 FIG. 2

INVENTOR. 3 S.D.COLLIE A T TORNE KS" United States Patent 3,405,858 ARTICLE PACKAGE CONVERTIBLE TO A CONTAINER Stafford D. Collie, Kansas City, Mo., assignor to Phillips Petroleum Company, a corporation of Delaware Filed Nov. 4, 1966, Ser. No. 592,158 Claims. (Cl. 229-) ABSTRACT OF THE DISCLOSURE In a cup-shaped package having a substantially continuous side wall and a bottom wall, the bottom wall comprises a central diaphragm portion, at least one sloping wall section extending from the side wall to the central diaphragm portion, and a plurality of spaced triangularly shaped channel-like members extending from the side wall to the central diaphragm portion. The diaphragm portion and the channel-like members are shaped to permit the vertical displacement of the sloping wall section and the diaphragm portion.

This invention relates to article packages which are convertible to containers or dishes. In one of its aspects, it relates to an article package which is convertible to a suitable container for the article by pushing in the bottom wall of the package, the bottom wall having a downwardly and inwardly sloping surface and a central diaphragm portion which is disposed upwardly within the package when the same is converted to a container.

The advent of thermoplastic materials such as polyethylene and polystyrene have precipitated a revolution in the packaging field. Many new packages or articles have been devised. Generally, once the article is ready to be consumed, the package is not useable. This is especially true in the case of articles such as soap.

I have now discovered an article package which can be converted to a container, for example, a soap dish, after the package is opened.

By various aspects of this invention, one or more of the following or other objects can be obtained.

It is an object of this invention to provide an article package which is convertible into a useable container from which the article can be easily removed.

It is a further object of this invention to provide a soap package which is convertible to a soap dish.

Other aspects, objects and the several advantages of this invention are apparent to one skilled in the art from a study of this disclosure, the drawings, and the appended claims.

According to the invention, there is provided an article package which is convertible to a container or dish-shaped holder for the article. The package is generally cup-shaped with a substantially continuous side wall integral with a bottom wall which bottom wall contains at least one generally downwardly and inwardly sloping wall section, the sloping wall section extending from the side wall to a central diaphragm area which central diaphragm area is so shaped that upward pressure on the same with relation to the side walls causes said diaphragm portion and said sloping wall section to be displaced upwardly until the sloping wall sections slope upwardly and inwardly in a stable position.

The invention will now be described with reference to the accompanying drawings in which FIGURE 1 is an elevational view of a container according to the invention, FIGURE 2 is a top view of the container shown in FIGURE 1, and FIGURE 3 is a sectional view through lines 33 of the container shown in FIGURE 2 in the modified position.

Referring now to the drawings, there is provided a cupshaped package having side walls 2 with an upper rim 16 at the top thereof. The rim can be used for closing the package by placing a cover having a downwardly extending flange with interlocking grooves for rim 16. The bottom 4 of the package contains a plurality of supporting members 8 which are triangularly shaped and extend from the rounded corner 18 substantially vertically downwardly and then extend inwardly to a central diaphragm area 10, interspersed between each supporting means 8 are generally downwardly and inwardly sloping walls 6 which extend from the side walls 2 to the central diaphragm area 10.

The central diaphragm area 10 is preferably frustopyramidally shaped having walls 12 extending upwardly and a central upwardly concave area 14.

When it is desirable to convert the package into a dish or container, pressure is applied upwardly in the central diaphragm area 10 to cause movement of the sloping wall section 6 and the central diaphragm area 10 upwardly. Movement of the wall 6 will continue until a stable position is reached, as shown in FIGURE 3. Generally, the angle the wall 6 makes with the horizontal will be the same in FIGURE 3 as FIGURE 1 except that the angle will be upward with respect to the horizontal in FIGURE 3 and downward with respect to the horizontal in FIG- URE l (with respect to the junction of the sloping walls 6 with the side walls 2). The concave upward shape of area 14 provides flexibility for the bottom so that the bot tom wall can contract during the transition from the package to the container or dish. As can be seen from FIGURE 3, when the soap or other article is placed in the converted dish of FIGURE 3, it will protrude substantially above rim 16, thereby facilitating the removal of the article. This novel convertible package is especially adaptable to the packaging of soap bars.

As is understood by one skilled in the art, the package can be closed in any known manner. For example, the package could be wrapped with a transparent material or a lid could be sealed on the top thereof.

Whereas the invention has been described with regard to a rectangularly shaped package, it is within the scope of the invention to provide any shaped package, i.e., round, triangular, pentagonal, hexagonal, etc., and to accordingly provide less than or more than four supporting members 8. Generally, at least three supporting members will be desired to provide a stable dish. However, the invention is still operable when no supporting members are provided. Supporting members are preferred, however, since the shape of these supporting members, i.e., the triangularly shaped channel of like members 8, aids in the contraction of the bottom in the transition from the package to the container or dish. The rounded corner 18 serves as a hinge for the rotation of supporting members 8 during the transition from the package to the container or dish.

Further, the frusto-pyramidal shape of the central dia phragm area 10, although preferred, is not essential. A suitable convertible package could be made by using only the concave upwardly shaped portion 14 of the central diaphragm area 10. Alternately, any other shaped portion could be used which would allow the bottom to flex sutficiently so that the bottom could be transformed from the package to the container or dish.

As can be seen from FIGURE 3, the platform provided by portion 14 in combination with the downwardly sloping walls 6 provides an excellent place for water to drain from a soap bar which is placed on platform 14. It is within the scope of this invention to provide drain holes within support members 8 or in the bottom portion of sloping wall 6.

The package according to the invention can be manufactured from any thermoplastic material which has substantial flexibility to permit the transformation from the package to the container or dish as has been described hereinbefore. The examples of such materials are polyethylene, polypropylene, polybutene-l, polystyrene, polyvinylchloride, and the like.

Reasonable variation and modification are possible within the scope of the foregoing disclosure, the drawings, and the claims to theinvention without departing from the spirit thereof.
