INSULATED COASTER FOR GLASSES, CANS, BOTTLES OR THE LIKE Filed Feb. 15, 1965 United States Patent Ofilice 3,285,456 Patented Nov. 15, 1966 3,285,456 INSULATED CQASTER FOR GLASSES, CANS, BOTTLES, OR THE LIKE Bernard B. Pewitt, Bexar County, Tex. (Rte. 1, Box 16A, Wetmore, Tex.) Filed Feb. 15, 1965, Ser. No. 432,553 15 Claims. (Cl. 215100.5)

This invention relates to coasters, and more particularly to an insulated coaster of molded expandable polystyrene combined with a cap of flexible resilient material which will automatically effect a grip with a drinking glass, can, bottle or the like, form a trap for catching condensation, and becomes a means for keeping an iced drink cold for a considerable period of time or until consumed, and, conversely, to keep a heated drink hot for a longer time than would be normal with-out insulation.

The objects of the present invention are to provide a coaster, with a magnetic base, of two separable members, i.e., an insulative main body and a flexible and resilient plastic cap, whereby the parts may be quickly and easily "assembled and locked together, to provide such an in sulated coaster structure with inwardly directed blades or vanes which will be deflected sideways and/or downward upon insertion of a drinking glass, can or bottle to form gripping means, thereby holding the glass or the like securely within the insulated coaster structure and with an inner ring which cooperates to contain and hold water or moisture that has drained int-o the coaster and prevent same from spilling therefrom.

In accomplishing these and other objects of the present invention, I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

FIG. 1 is a plan view showing the general arrangement of the cap or top assembly with the vanes or blades 12 in vertical position and showing the sideways deflection caused when a glass 14 or the like is inserted therein.

FIG. 2 is a partial plan view of another embodiment showing the blades or vanes 13 in horizontal position.

FIG. 3 is an enlarged sectional view through the cap or top ring taken on the line 33, FIG. 1.

FIG. 4 is an enlarged sectional view through the top portion of the assembled coaster taken on the line 4-4, FIG. 1.

FIG. 5 is a cross-sectional view through the assembled coaster taken on the line 55, FIG. 1.

FIG. 6 is an enlarged sectional view through the top portion of the assembled coaster taken on the line 66, FIG. 2.

Referring more in detail to the drawings:

The coaster consists of a cup-like main body 1, molded or otherwise made of flexible resilient material having insulative qualities, having a bottom wall, with 'an Alnico magnet 4 embedded or recessed therein, and a circular side wall extending upward from the bottom wall and terminating in a beaded edge 16 or an inverted ledge of increased thickness defining an open upper end of the cup-like body member 1, which engages the cap member 2 as later described.

The cap member 2 is preferably formed of flexible resilient plastic or the like, and has an annular ring 5 of thickened cross-section with a sloping and inwardly projecting ledge 6 located on the inner surface of said annular ring 5. The outer cap wall 7 is joined to the annular ring 5, extends upward, then inward around a smooth radius and thence downward to become the middle or intermediate wall 9, said configuration forming a locking rim to engage the upper edge of the main body 1. Wall 8 is attached to the upper and inner surface of the aforesaid locking rim, extends inward and upward, around a smooth radius, and then downward to form a vertical coaster.

cylinder wall 11, said configuration forming a liquidretaining chamber when the coaster is positioned in degrees of inversion, and a plurality of web members 10 are molded and join wall 11, wall 8 and the upper portion of wall 9 together to reinforce and impart a certain degree of rigidity to the vertical cylinder wall 11. A plurality of inwardly directed blades or vanes, shown as vertical 12 and horizontal 13, are positioned around and attached to the inner surface of the vertical wall 11. It is intended to use the best combination of blades or vanes to adequately secure the glass, bottle or can within the coaster, whether this necessitates all vertical, all horizontal, a combination thereof, or some, as yet, undetermined angle between the vertical and horizontal positions as shown in the drawings.

It is assumed that these coasters may be used in automobiles and rested on reasonably flat metallic surfaces having magnetic properties, thus it is also the object of the present invention'to provide a coaster with an Alni co or other permanent magnet 4 embedded or recessed into the base thereof to hold the coaster on a reasonably flat metallic surface having magnetic properties and thus resist movement of the coaster due to vibration or sliding due to abrupt changes in direction of the vehicle while in motion.

The cross-sectional view of FIG. 3 shows a cross-section of the molded cap member 2 in a state of rest, as molded, and before insertion on the main body 1. It will be seen in FIG. 4 that application of the cap member 2 to the main body 1 causes the annular ring 5 to stretch or dilate slightly causing a ring stress to be introduced into the annular ring 5. When the internal projection 6 is forced down slightlybelow the inverted ledge 15 located on the upper edge of the main body 1, the resilient properties of the material of the cap member 2 cause contraction of the annular ring S'toward the original and smaller diameter thereof, and causes a snug fit around the perimeter of the upper edge of the main body 1. It will also be seen that wall 9 is deflected inward slightly, due to the inwardly tapering inner wide wall of the main member 1, effecting a tight seal between wall 9 and the cup body adjacent thereto. I

For the purposes and intended uses of the coaster, it is not necessary to dissassemble the two component parts, but due to the natural curiosity of many people, the cap member 2 and the main body 1 are so arranged that these parts can be separated and reassembled many times without damage to either part.

The vane 12 in FIG. 4 is shown attached in a vertical position to the vertical cylinder wall 11 and deflected sideways due to pressure exerted from the circumference of a glass, can or bottle 14, and the vane or blade 13 in FIG. 6 is shown attached in a horizontal position to the vertical cylinder wall 11 and deflected downward due to pressure exerted by inserting a glass or the like 14 inside the It is intended to use a combination of these plural blade or vane attachments to the vertical cylinder wall 11 in order to obtain the best arrangement, within these limits, for holding the glass, can or bottle 14 securely and centered within the rigid, web reinforced, vertical cylinder wall 11. Thus, insertion of a glass, can or bottle, of varying diameters, into the coaster, will deflect the vanes or blades downward, sideways or in a combination of these directions, thus holding the glass or the like securely within the insulated coaster.
