IAPEB DISH.

Application led latch 83, 1921. `8eria1'll'o.'454,772.

The present invention relates to paper dishes, that is, to dishes made of any suitable fibrous stock, whether paper or resembling paper, and particularly to such a dish having a re-enforced rim. The dish may be circular, polygonal, or any suitable form, molded or formed in any suitable way. rllhe paper stock-may be single or multiple ply with or without incorporatin a binder, andv 10 the dish may be coated with parailin or otherwise treated to resist moisture and to withstarfd washing.

The dish, which may consist of one Vpiece of stock, has a rim re-enforced to give strength and rigidity thereto.

which is preferably triple-enforced, 1s

' formed from a continuation yof the stock of the dish folded in overlying portions and .where triple-enforced, into three overlying portions. The inner surface of the -rim is referably made to liein uninterrupted conormity with the interiorsurface of the dish. Irrespective, however, of the continuity of the inner rim and dish surfaces, but prefer'- 26 ably embodying this construction, the dish may have an upturned side wall, the upper portion of which is recessed, and the folds of stock may be anchored in said recess. Furthermore, the rim may be highly compressed and practically solidified, in which case the folds thereof are rigidly set to pery manent gage dimensions. So formed and treated, the rim provides a substantial ref enforcement for the dish against deforma# tion in handling or in use. Where the rim is triple-enforced, the folds of stock may consist of a base portion, a reversely extending intermediate portion, and an enclosed terminal portion, the inner surface of the intermediate portion lying in uninterrupted conformit with the interior surface of the dish. In t e specific embodiment described hereinafter, the base and intermediate portions are joined by means ofa secedge of the terminal portion to form a flat edge for the dish, thus facilitating the handling thereof.

Irrespective of the manner in which the rim of the dish is re-enforced, the invention comprehends as another of its parts, a paper dish having an upturned side wall and a re-enforced rim formed from a continuation of the stock of the side wall folded into overlying portions, the bottom of the dish having an annular' depression which serves as The rim,

tion of stock lying flat over the peripheral a stand for the dish to keep the bottom thereof out of contact with wet or damp surfaces upon which the dish might be placed. Preferably the bottom of the dish is slightly concaved outwardly to provide against Warpmg and t'o increase the depth of the dlsh, and the annular depression is situated adjacent the upturned side wall to provide a stand of sufficient diameter to firmly supp ort the dish when in use. Preferably one side of the annular depression lies in uninterrupted conformity with the `upturned side wall so that the latter has aV rounded section of stock -joining it with the base tov sup- *port 1t 1n the upturned or inclined position.

The connecting section Vthus formed provldes a-stronger support for the side wall 4in a position inclined to the bottoml than would be provided were the connection a corner or sharp edge.

Whether or not the dish is provided with an annular depression to serve as a stand therefor, but preferably so, the invention comprehends as still another of its parts', a

one piece paper dish having a rim formed from a continuation. of the stock thereof which is convoluted, preferably outwardly j l of said dish, to form a re-enforced rim or bead. (Where the bead is highly compressed and practically solidified under great pressure the convolutions of stock are rigidly set topermanent gage dimensions and the rim re-enforces the dish against deformation under pressure in handling. The bottom of the dish may have an annular' depression to serve as a stand therefor, one side of which preferably' lies in uninterrupted conformity with the upturned side wall to providev a rounded connecting section betweenait and thebottom of the dish.

In the accompanying drawings illustrating the preferred embodiment of the invention in application, as an example, to a dish of single-ply stock,

Fig. 1 is a view in elevation of the dish partl in section and partly in full view; and ig. 2 is a plan view of the dish shown in Fig. 1.

In the embodiment illustrated in Fig. 1, the dish has aI bottom 1 slightly concaved outwardly, an upturned side wall 2, and a re-enforced rim 3. The rim 3 is formed from a continuation of the stock composing the dish and comprises a base portion 4, an intermediate portion 5, a section 6 joining the base and intermediate portions, and'a` terminal portion 7 enclosed between the base and intermediate portions. The joining section 6 lies flat over the raw edge of the terminal portion 7, so that said edge is concealed, and is also protected lfrom moisture, which might` otherwise have access thereto either from without the dish, when it is placed in water to be washed, or through capillary attraction from its contents. The inner surface of the rim lies in uninterrupted conformity with the inside surface of the dish. Thus while the inner surface of the rim is made to constitute part of the interior sur-k 'communicated to the bottom will not be concentrated at any one point between the side and bottom, but will be distributed throughout the entire curved portion, so that, while this portion may yield, under strain, it will be perfectly resilient and will always return to the form in which it was molded. As a result, the sides of the dish will not become distorted under ordinary conditions of use.

In the manufacture of the dish the resiliency and permanency of the curved connection portion or annular depression 9 is greatly increased during the molding operation, by so forming the molds or dies that the pressure to which this portion 9 is subjected, will be greatly in excess of that applied to the side and bottom, thereby causing this portion to be highly solidified.

The formation of the bottom 1 slightly concave is important in that this construction also assists in preventing deformation n use much more effectively than if it were The folds of subjected, in forming,to a pressure preferably of about 4000 to 6000 pounds per square inch, under which pressure the parts become highly compressed and practically solidifiedv and are rigidly set to permanent gage dimensions.

Having thus described my invention, what I claim is: j

As a new article of manufacture, a pa er dish formed from an vintegral paper dlsk, an upturned flaring outer rim having a recessed upper portion, and a multi-reenforced marginal portion of said rim formed from a continuation of the stock thereofv folded into stock composing the rim are paper dish formed from an integral paper disk, and comprising an upturned flaring outer rim having a`recessed upper portion, and a highly compressed and vpractically solidified multi-reenforced marginal portion of said rim formed from a continuation of the stock thereof folded into three overlying rigidly-set portions, said overlying portions being located in said recessed upper portion.

4. As a new article of manufacture, a paper dish formed from an integral paper disk, and comprising a multi-reenforced flaring outer rim formed from a continuation of the stock thereof and comprising a base portion, a reversely extending intermediate portion, and an enclosed terminal portion, the inner surface of said intermediate portion'lying in uninterrupted conformity with the interior surface of the dish.
