Aug. 28, 1934. yH. B. vcom lNs 15971337 coAsTER PAD Filed Feb. 29, 1952 Patented Aug. 28, 1934 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to coaster pads, and more particularly relates to a type of coaster pad upon which a tumbler or other container for liquids may be placed.

5 It is well known that in serving a beverage, moisture collects on the outside of its container due either to frosting or to the spilling of the contents. Such moisture may mar the finish of furniture or stain the linen covering the furniture,

and it is the purpose of this invention to provide means of overcoming this disadvantage.

The means heretofore devised for obtaining this result have neither been economical nor have they presented a means for eliminating the moisture from the bottom of the tumbler or other container so that when the tumbler was picked up the drops of the liquid would not fall from the glass.

Another disadvantage of coaster pads heretofore known was that a moist tumbler would frequently adhere to the coaster so that when it was lifted the coaster pad would adhere thereto until some distance above its supporting surface and then drop and spill its contents.

It is an object of my invention to provide means which will absorb the moisture from the bottom of the tumbler, which means will at the same time be kept out of contact with the supporting surface.

It is a further object of my invention to provide a coaster to which a glass lled with the usual beverage substances will not adhere.

Other objects and advantages will be apparent from the following specification and drawing, in which I have illustrated an embodiment of my invention, in which:

Figure 1 is a perspective view of my improved coaster pad with portions broken away to indicate the texture of the various layers, and

Fig. 2 is a sectional elevation of the coaster pad on the line 2 2, Fig. 1.

I attain my objects by the provision of a multiple-ply coaster pad which may be of any desired shape; that illustrated being circular and of a size suitable for supporting a tumbler or other beverage container. Obviously, as will hereafter be apparent, the coaster pad may be of whatever size and shape is found desirable and which may appeal to the trade, for supporting not only tumblers but pitchers, punch-bowls and other containers with'which it is necessary or desirable to use a support or pad of the coaster type.

Referring particularly to Fig. 1, the coaster may comprise an upper layer of an absorbent material indicated at 1, a layer of adhesive material 2, and a layer of paper, card board, or any suitable cellulosic material 3. The layer of absorbent material is preferably a relatively thick sheet of blotting paper. The layer of adhesive is of a waterand moisture-proof nature and is preferably a bituminous material. This waterproofing layer may be in the nature of asphaltum or may equally well, if less expensive and satisfactory material can be found, be any suitable waterproof adhesive such, for instance, as rubber cement. The lower layer 3 is of a suitable paper or similar 65 material having a smooth exposed surface. If a stiffer pad is desired, the lower layer may be of stiff card board, suitably waterproofed; wood; latex paper or any suitable material which will not mar the surface upon which it may be placed. If a waterproof lower layer is used, such as wood or a latex paper the adhesive need not be water-Y proof.

By the provision of the upper layer of absorbent material l, such as blotting paper, I provide means whereby any moisture which may be found on the outer portion of the glass will be readily absorbed as it falls to the coaster pad and will not form a bond between the glass and the coaster pad as has frequently occurred in the types of coaster pads heretofore used. By the same means I eliminate from the bottom of the glass drops of liquid which formerly fell therefrom when it was lifted from coasters of the usual type. While doing this I preserve the table from contact with the moisture by the use of the waterproof intervening layer of asphaltum or other material between the absorbent material and the base support for the same.

Obviously, various changes may be made in the materials used from those specifically enumerated but preserving the combination of an absorbent upper surface and a moisture-proof lower surface in a coaster, and modifications may be made from the above described embodiment of my invention without departing from the spirit and scope thereof as set forth in the following claim.

I claim: t

As a new article of manufacture, a laminated coaster pad for individual liquid-containing vessels, comprising a structure consisting of an upper layer of blotting paper presenting a continuous surface, a bottom layer of relatively stiff paper presenting a continuous surface, and a continuous layer of bituminous material disposedbetween and connecting said upper and bottom layers and permanently adherent to both of the same; said layer of blotting paper being materially thicker than the bottom layer.

I HAROLD B. COLLINS.
