Abstract

A receptacle which may be used for different purposes such as an ashtray or as a coaster on which a glass, which contains a beverage, for example, may be placed. The receptacle has an inner glass dish which is provided with an endless sidewall extending upwardly from and surrounding its bottom wall and terminating at its top end in an outwardly directed peripheral flange. This inner dish is surrounded by an outer ring which has an inner peripheral flange extending beneath and overlapping the outer flange of the inner dish. In this way the receptacle is made of a pair of components which will have a minimum possibility of distortion when these components are molded using glass for the receptacle and plastic for the outer ring.

Description

United States Patent Primary ExaminerDonald F. Norton AttorneyBlum, Moscovitz, Friedman & Kaplan ABSTRACT: A receptacle which may be used for different purposes such as an ashtray or as a coaster on which a glass, which contains a beverage, for example, may be placed. The receptacle has an inner glass dish which is provided with an endless sidewall extending upwardly from and surrounding its bottom wall and terminating at its top end in an outwardly directed peripheral flange. This inner dish is surrounded by an outer ring which has an inner peripheral flange extending beneath and overlapping the outer flange of the inner dish. In this way the receptacle is made of a pair of components which will have a minimum possibility of distortion when these components are molded using glass for the receptacle and plastic for the outer ring.

RECEP'IACLES BACKGROUND OF THE INVENTION The present invention relates to receptacles.

In particular, the present invention relates to receptacles in the form of relatively shallow dished structures capable of being used for many different purposes. Thus, such structures may be used as ash trays, or they may be used as coasters for beverage-containing glasses.

It has been customary to mold such receptacles from glass, and with the presently known molding techniques a relatively large number of such glass receptacles, which are conventionally molded in one piece, become unavoidably distorted while cooling. Of course, such distorted pieces must be rejected, so that the cost of manufacture of such receptacles is undesirably high.

SUMMARY OF THE INVENTION It is accordingly a primary object of the invention to provide a receptacle of the above type which will avoid the above drawbacks.

In particular, it is an object of the invention to provide a receptacle construction which will very greatly reduce the possibility of distortion during setting of the glass which forms only the receptacle and is not of complex cross section so that the number of rejects is very greatly reduced with the structure of the invention.

At the same time, it is an object of the invention to keep the structure of the receptacle quite simple so that it can be inexpensively manufactured.

Furthermore, it is an object of the invention to provide a receptacle of the above general type which lends itself to combination with coverings of silver or the like, which may be used for protective and decorative purposes.

According to the invention, the receptacle includes an inner dish having a bottom wall surrounded by a sidewall, which latter extends upwardly from the bottom wall. This sidewall is provided at its upper region with an outwardly directed peripheral flange. The receptacle further includes an outer ring which is separate from and surrounds the inner dish and which has an inner peripheral flange overlapping and extending beneath the outer peripheral flange of the inner dish. As a result of making the receptacle from a pair of components, namely the dish and ring referred to above, these separate components have practically no tendency to become distorted during cooling and solidification. They are separately molded, the dish of glassand the ring of plastic, with each component having a cross Zection which is relatively simple as compared to the cross section of a one-piece receptacle of a corresponding total configuration, so that in this way the possibility of distortion is substantially eliminated. At the same time the outer plastic ring lends itself to being covered with a suitable protective as well as decorative covering sheet or like element which can be separately applied to the ring with the dish itself being separately formed and easily assembled with the ring, as by being deposited in the space which is surrounded by the ring with its flange resting on the inner peripheral flange of the ring.

BRIEF DESCRIPTION OF DRAWINGS The invention illustrated by way of example in the accompanying drawings which form part of this application and in which:

FIG. I is an exploded perspective illustration of an embodiment of a receptacle according to the invention;

FIG. 2 is a top plan view of the receptacle of the invention;

FIG. 3 is a transverse fragmentary section, on an enlarged scale as compared to FIG. 2, taken along line 3-3 FIG. 2 in the direction of the arrows and showing the details of the structure at the place where the dish and the ring coact.

DESCRIPTION OF A PREFERRED EMBODIMENT Referring to the drawings, the receptacle 10 of the present invention includes an inner glass dish 12 and an outer plastic ring 14. These

components

12 and 14 are separately illustrated in FIG. 1.

The inner dish 12 has a bottom wall 16 surrounded by and integral with a sidewall 18 which extends upwardly from the bottom wall. This sidewall 18 terminates at its upper end in an outwardly directed peripheral flange 20, as shown most clearly in FIG. 3.

The glass dish 12 may be molded in any well-known manner. Because of the relatively simple configuration of the dish 12, it will have practically no tendency to become distorted during solidification and setting.

The plastic ring 14 surrounds the dish 12 and has an inner peripheral flange 22 extending beneath and overlapping the outer flange 20 of the dish 12. Thus, the ring 14 surrounds a space into which the dish 12 may be deposited with the flange 20 overlapping the flange 22. Through this simple expedient it is possible to assemble the

components

12 and 14 which form the receptacle 10.

It will be noted that the flange 22 has the configuration of a cylinder surrounding the central vertical axis of the dish 12, this axis forming the axis of the cylinder formed by the flange 22. This flange 22 has axially of the cylinder a length substantially greater than the thickness of the flange 22. Furthermore it will be noted that the dish 12 has an exterior side surface 24 which tapers inwardly away from the flange 22 so as to have a slight clearance with the respect thereto, as indicated in FIG. 3.

The ring I4 is in the form of an annular channel having a downwardly directed hollow interior limited at the inside by the flange 22 and at the outside wall 26 which extends down approximately to the elevation of the bottom surface of the bottom wall 16 of the dish 12. Thus, this ring 14 has an outer exterior surface extending beyond the outer flange 20 of the dish 12. This exterior surface of the ring 14 may be covered with a suitable ring-shaped fllm or sheet 28 which may be decorative and which at the same time may be made of a protective metal such as silver. For example the covering 28 of silver is clinched into the ring so that in this way the ring 14 is protected.

Since the ring 14 is separate from the dish 12 it is an exceedingly simple matter to provide it with a protective and/or decorative medium 28 which does not form a part of the dish 12.

Furthermore, because of the relatively simple cross-sectional configuration of the

components

12 and 14 they will have very little if any tendency to become deformed during solidification and setting. If there is any slight deformation it will easily be accommodated by the clearance between the flange 22 and the outer side surface 24. The inner dish 12 can at any time be removed from the space surrounded by the ring 14 simply by being displaced upwardly out of this space. Furthermore, when the ring 14 is raised the dish 12 will be raised therewith.

It is to be noted that if the

components

12 and 14 were integrally molded to provide a one-piece construction for the receptacle 10, then a relatively large number of these pieces would become deformed during solidification and setting, so that under these conditions an undesirably large number of rejects would be encountered. In contrast, by making the receptacle 10 of the

components

12 and 14 as described above this disadvantage is avoided with the added advantage of the relatively inexpensive structures of the

components

12 and 14 and the possibility of treating the latter independently of the dish I2, as providing the ring 14 with the protective and decorative medium.

In addition, if it should happen that dish 12 breaks, it is a simple matter to replace it with another dish 12 without replacing the ring 14. Moreover, it is possible to have several sets of rings 14 and several sets of dishes 12 of different colors,

for-example, enabling difl'erent combinations of

rings

12 and 14 to be put togetheras desired.

This structure described above may be used as an ashtray and as a support for a beverage-containing glass, in which case the receptacle of the invention would function as a coaster.
