INFANTS DRINKING MUG Filed July 25, 1949 INVENTOR.

Application July 23, 1949, Serial No. 106,390

1 Claim.

This invention relates generally to vessels or containers and, more specifically, to drinking vessels such as cups, glasses, tumblers, mugs and surface, the lowermost portion of the mug bottom which first contacts the tray acts as a fulcrum about which the mug is apt to tilt to a recumbent position.

Furthermore, the ordinary mug used by children upsets quite readily when struck or pushed"- sidewise, as it frequently is by its user.

My present invention is designed to prevent the usually frequent accidental spilling of their beverages by children or the upsetting of any similar vessel or container. With this end in view,"

it contemplates the provision of a drinking mug or other vessel or container which will not readily upset when struck or pushed sidewise and which, when deposited on a tray or other supporting surface, will automatically, under ordinary conditions, assume an upright position.

In carrying out the conception of my invention I propose to provide a drinking vessel or container, preferably in the form of a mug or other vessel having a low center of gravity, with a base which extends radially a substantial distance or distances in all directions from the bottom of the mug.

A preferred embodiment of my invention is illustrated in the accompanying drawings from which, when considered in connection with the following description, its structural features and the attendant advantages thereof should be readily appreciated.

Referring to the drawings,

Fig. 1 is a perspective of a drinking mug constructed in accordance with my invention;

Fig. 2 is a plan view thereof; and

Fig.3 is a sectional view on the line 33 of Fig. 2.

Referring now to the drawings more in it will be observed that the mug as illustrated comprises a body 5 preferably substantially cylindrical in contour, equipped in this instance with a handle 6, although in many instances it may be preferable to employ a plurality of handles or none.

The bottom of the body is provided with a detail,

base I which surrounds and extends radially outwardly in all directions from the lower end of the mug. This base may be formed integrally with the body of the mug, as, for instance, by a molding process if the mug be made of plastic or ceramic material or glass or other suitable material, or, if preferred, the mug body and the base may be formed structurally independent of each other and rigidly secured together by a fusion process, or by the employment of a suitable adhesive.

.The shape of the base I may vary in accordand with the manufacturers views but, preferably, it is polygonal in contour, and for illustrative purposes I have herein shown it as being substantially square. In any event, the base extends outwardly from the mug bottom a willcient distance to impart great stability to the mug so that it cannot be readily upset by striking it or pushing it laterally, obliquely or in any other plane. Furthermore, when the user lowers the mug in an inclined position onto a tray or other surface, an edge or a corner of the base will be first to contact the surface and will act as a fulcrum about which the mug will tilt to assume an upright position. The low center of gravity of the mug assists in the attainment of this result.

The dimensions of the mug body and the base may, of course, be varied, and although the most satisfactory results are attained if the axial dimensions of the mug body are less than the minimum diametral dimensions of the base, the ratio of the base dimensions and the axial dimensions may vary considerably and still impart practical stability to the container or vessel.

It should be apparent from the foregoing that I have provided a container or vessel which, because of its stability and its tendency to automatically assume and maintain an upright position, will be most satisfactory for use by preventing spilling of its contents.

I claim:

' An infants drinking mug having an enlarged and stable base comprising a container provided with a, handle and an integral, fiat and substantially square base of substantially greater thickness than the thickness of the side wall of the container with the side wall merging into the flat base, said base projecting outwardly in a horizontal plane from the bottom and outer periphery of the container so that the container is disposed a substantial amount inwardly from the periphery of the base and the base presents a relatively wide and symmetrical flange encompassing the container and projecting outwardly a. substantial amount from the periphery of the container, said base having a low center of gravity imparting stability to the container and causing UNITED STATES PATENTS Number D. 22,171 D. 24,576

it to assume and maintain an upright position 5 170,329

whereby the danger of tipping and spillage of the contents of the container is greatly minimized EDWIN S. SINAIKO.
