CONTAINER AND LINER THEREFOR James B. Luck, Providence, B. 1., and Harry M. Chatto, Cambridge, Mass.

Application August 12,1935, Serial No. 35,100 l 12 Claims. (01. 65-15) 10 in the home or in camping service as it will remove in large part the drudgery ofdishwashing,

which at all times is unpleasant and in cases.

where food has become adherent to the dish is a particularly difficult and objectionable task.

15 The modern so-called paper or paper pulp dish has been developed to the point where it is serviceable and satisfactory under many conditions, but

the public has not yet accepted it as a substitute I for china, silver or other fine table ware, and in 2 fact, it still falls far short of complete satisfaction under certain conditions. For example, when used as a pie plate, the knife which cuts the pie is also liable to cut into or through the pulp plate .with obvious unpleasant results. Such ware or 25 other molded cellulose fibre product, however, lends itself quite satisfactorily to the construction of our liner.

Although there seems to exist some aversion to the service of food on a paper or paper pulp dish, 3 nevertheless, there appears to be just as definite a liking for a lined dish, and linings are used not only for utilitarian purposes, but also for decoration and frequently in fine service asa last dainty finish. A white paper or paper pulp lining with- 35 in or upon a fine china or silver dish seems to convey a suggestion of individual daintiness, cleanliness and freedom from objectionable contacts. Such a suggestion is even more pronounced with cheaper crockery or metal ware and 40 when used in the cheaper line of eating places.

' The practical advantages of -such a liner are obvious. Notonly is dishwashing greatly reduced, but the supporting dishes may be kept either hot or chill d as desired and thus tend to keep the food ser ed in the liner in similar condition. After use the liner may readily be removed and discarded v v v The advantages following the use of our liner in mixing and cooking dishes are particularly 50 noteworthy. Instead of the necessity of scraping or soaking adherent material from the dish, our liner is simply disengaged therefrom and burned or otherwise disposed of. v I One of the main objections to dish lining de- 55 vices heretofore used was the difiiculty of retaining or locking the same in position on the supporting dish or holder. To avoid this various expedients 'were suggested, such as corrugating the lining, or perforating or otherwise breaking the rim of the dish to receive protuberances' on the 5 liner, all of which required change from the usual standard dish to such a degree as to make the use of the same. impracticable, undesirable and unsightly. While we propose to use with our liner a dish or holder so constructed as to prevent dislodg ment of the liner during use, it is our object to accomplish this without the necessity for any unduly obvious or unaesthetic mechanical features of. construction which would tend to mar and alter the standard simple line and pleasing appearance of the traditionally accepted plates and bowls of the table and kitchen service.

Briefiy, we propose to hold the liner resiliently in its dish or holder. This is satisfactorily accomplished when the liner is made of paper pulp or other moldable cellulose fibre product and is provided with a rim portion which may be formed with curved arched surfaces or bows, singly or in greater number, which add to the natural slight resiliency of the stock enough spring to permit the same to be snapped into position in the holder and to be held there againstmovementso long as desired. It is essential that our liner be made of premolded pulp or other self-sustaining material with enough rigidity to retain its desired form, and in this respect our invention represents improvement over the many proposed paperlinings of the prior art which relied entirely on the dish on which they rested to furnish their support, or required pleating, crimping or other mechanical device to impart the required rigidity to the liner. We provide a smooth-surfaced, molded liner which is entirely self-supporting and is adapted to be inserted within a container of crockery, metal, or other rigid material for the purposes of protecting such containers.

In the accompanying drawing we have illustrated and in the following specification describe certain embodiments of our invention which we have found successful in practical use. Throughout the specification and drawing-like reference numerals are employed to indicate corresponding parts, and in the drawing:

' tain its shape.

Zhollier I, iroi' permanent,v multi-use material and the liner 2 is of single use, destructible material. The material of the liner may be of molded fibre pulp or other cellulose fibre capable of" being molded to desired form and producing a self-supporting body as above suggested as distinguished from ordinary folded or pressed paper or other material requiring foldin Dressing or other mechanical reinforcement to main- The holder I may be any desired hollow dish, plate, bowl or othercontainer, the plate showin is provided with an upwardly extending flange In which is provided with means to hold the resilient, yielding, arched edge of the liner 2 within the holder l. Broadly, this is effected by forming' the upwardly extending flange or side wall |a,' which as illustrated may be outwardly flaring, with a groove or indentation'3 into which the edge of the resilient rim l of the liner 2 may be sprung.

In the form of holder illustrated in Figs. 1 and 2, the wall of the holder l flares outwardly as at 5, and is then turned upwardly and inwardly as at 6 to form the groove 3 for the edge of the liner, and thence upwardly and outwardly to provide a guide or lead-in portion 6' over which the edge orperimeter of the resilient or yielding rim of the liner 2 is guided and sprung and which retains the liner in the container until removed as hereinafter described. Beyond the portion 6' the rim curves downwardly as at 'l and may have a beaded edge 8.

The wall and rim of the holder may be modifled considerably as to any desired form or bear any desired decoration. The rim 1 outwardly of the groove 3 is desirable as a neat, pleasing and contrasting ornamental feature and also as a means of gripping the assembled device, but is not always used, as for example, in straight sided dishes. v

Our liner is preferably of the same contours and of dimensions to permit the base of the liner to lie snugly and flat upon the base of the holder I. When the liner is used as a plate in table or camping service, the snug fit on base and side of the plate, serves to prevent the edge of a knife puncturing the plate as would likely occur if the plate had no backing.

In the construction of the liner illustrated in Fig. l, the sidewall flares outwardly at In to form a substantially horizontally disposed bow 4, the edge of which is adapted to be flexed inwardly to permit its being snapped into the groove 3, in the holder.

One of the essential features of this construction of the liner is the bow or concentric arched or curved portion 4 of the rim by which the outer rim edge is resilientlyyieldable to be snapped into locking relation with the rigid cooperating concentric overhanging locking edge 6' of the supporting plate or holder which overhangs the groove 3.

The how 4 is of such extent that when the liner 2 is locked in the holder I, the bow 4- extends upwardly above the rim portions 1 and} and forms a rest or support for a metal knife, spoon or other serving device and serves to prevent a metal to metal contact. By means of utilizing the fibre liner as a rest for such articles, the rattle and noise usually accompanying the com it of the same with the holder is avoided. Such a spacing means also serves to prevent any food particles remaining on a knife or fork from being deposited on the rim of the metal container.

The modified construction of Fig. 3 includes double reverse curves or bows la and lib in the rim of the holder, the portions 5b merging into the upright portion 5c. The liner 2 is similarly curved as at la and lb, the portion in extending above the holder rim as did the bow 4 and the other portion 4b being fore-shortened and having its edge abutting the upright 50, to hold the liner .under compression in the holder. The

.- double-bowed construction of this form of our being illustrative only. -In each case the holder double. arch but under most circumstances the simpler engagement of Figs. 1 and 2 is wholly satisfactory.

In an assembly of holder and liner, the liner may be removed by inserting the fingers through the openings 9 provided in the wall of the holder. Upon application of slight pressure the resilient rim of the liner is disengaged from the holder which is ready to receive a new liner.

The form of liner shown in Fig. 3 is readily inserted'in the holder as it may simply be pressed downwardly until the edge slips past the slight curve of the inturned upright 50 and locks in the depression 3.

We preferably dispose the finger holes 9 or resilient tongues or other disengaging means in the upwardly extending flange la adjacent the receiving groove for the resilient rim. This allows for a dislodging, warping movement of the liner rim by which the slight tension set up by springing it into place is relieved. This frees the rim edge and the liner is loose and ready for removal without puncture, rupture or distortion that might spill any food particles left in the ner.

We are aware of the use of ejector apertures in cans, containers or other holders through which the contents or lining can be poked out or ejected. We do not therefore claim such broadly but only as a simple and inexpensive means of breaking or relieving the tensioned rim edge engagement of our resilient liners to free the radial stress set up when they are sprung into place in the rigid holder in our combination.

The visible metal edge I of the holder adds greatly to the beauty of the dish and the raised bound rim or brim 4-4a of the liner protects the holder edge I from soil or noisy metal conact.

As suggested above, the liner need be supported by the holder only on the base and rim, the liner being made of stock of sufficient body and rigidity to support itself. If desired, the liner may be decorated to accord to the color scheme or to give the general appearance sought in the service.

The shape of the dish is immaterial and may be circular or rectangular, the liner being capable of being produced in any desired shape and being adapted to use whether in a mixing, cooking or serving dish. In all of these constructions only designs which may be molded are desirable as only in molded pulp devices can be found the combined rigidity and resiliency which are essential to the assembly of our liner within its holder.

Any modification in the form of construction within these limits may be resorted to without departing from the spirit of our invention if within the limits of the appended claims.
