FLAKMINATED VESSEL Ernest Jr., Fresno, Calif. Application February 11, 1947, Serial No. 727,832

1 Claim. (01. 65-15) This invention relates to dishes or receptacles.

"' An object of this invention is to provide a dish or receptacle which is formed of a plurality of laminations which are detachably secured to a base dish or receptacle so that a clean surface may be provided without washin or otherwise cleaning the article.

Another object of this invention is to provide a dish .or' receptacle which includes a plurality bf removable laminations, and means in the form of tear strips to facilitate the removal operation of each lamination.

' A further object of this invention is to provide a dish or receptacle in which the removable laminations may be formed of relatively flexible material, such as paper, plastic sheets, or the like which are moistureproof so that the succeeding laminations will not be damaged through use of the outermost lamination.

A further object of this invention is to provide a dish or receptacle of this kind wherein the free end or tab of each tear strip is provided with an identifying numeral so that the user will know at a glance the number of laminations which remain about the base receptacle.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claim appended hereto.

In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 1 is a top plan view of a plate, partly broken away, constructed according to an embodiment of this invention.

Figure 2 is a bottom plan view, partly broken away of the plate. 1

Figure '3 is a sectional view, partly broken away, on an enlarged scale, taken on the line 3-3 of Fig. 1.

Figure 4 is a fragmentary sectional view taken on the line 4--4 of Fig. 3.

Figure 5 is a fragmentary sectional view taken on the line 5-5 of Fig. 3.

Referring to the drawing, the numeral l0 designatesgenerally a base plate or receptacle which may be formed of such material as will give the base plate substantial rigidity and which is of a character such that the base plate will not readily break or crack. As an example, the base plate Ill may be formed out of -plastlc or composition material, or may be formed out of compresse'dand heat treated fibrous material which is impregnated with moistureproof and heat resistance material. In the present instance the plate In comprises a bottom ll having a flared rim l2 extending therefrom, and an annular rib I3 is disposed on the lower side of the bottom H. It will be understood that the plateherein disclosed is only one application of this invention, and that the term plate or dish as herein used will also include cups, saucers, and other vessels which are used in holding edibles. The plate in has a plurality of relatively thin superposed laminations or covers disposed there on, the laminations being designated by. the numeral I. These laminations 14 are of relatively flexible "characteristic and may be formed 91 moistureproofed paper, plastic, or other contiposition material which has the additional characteristic" of resisting heat and preventing the saturation of the lamination by the juices of vegetable, meats, fruits, or other edibles.

Each lamination I4 includes a central part I5 engaging over the bottom ll of the plate, an upwardly and outwardly flared rim covering part 16 which is bent over the outer edge of the rim 42 as indicated at IT, and is then bent or folded inwardly and downwardly as indicated at l8 on the lower side of the rim 12. The reverted or folded part l8 of the lamination l4 terminates outwardly from the annular bead l3, as clearly indicated in Fig. 3.

The innermost lamination I4 is secured to the inside of the plate III by means of adhesive [9 which secures this lamination to the plate ID at the junction between the bottom 1 l and the rim I2. Each succeeding lamination I4 is secured to the next inner lamination by additional rings of adhesive I9, so that all of the laminations will be firmly secured together and to the plate in order that the nested laminations will very closely follow the configuration of the plate Ill.

On the outer or lower side of the rim l2, each lamination is securedto the rim by means of adhesive 20 and the outer lower portions of the laminations are secured together by similar rings of adhesive 20.

In order to provide a means whereby each lamination may be removed from the plate, I have provided a tear strip 2! which is fixedly secured to each lamination outwardly from the ring of adhesive 20. Each tear strip 2| is provided with a free end .or tab 22, and the tab 22 has a numeral 23 printed orstamped thereon to indicate the number of the lamination. These lamination identifyingmumerals 23 are arranged in inverse order, that is, the innermost lamination is identified by-the number 1, and the outer lamination by the last number. While there are four laminations shown in the drawing, there may be as many laminations as may be'desired.

In the formation of this plate or vessel, the base. I0 is shaped or molded to the desired configuration and the laminations M are secured to the inside of the plate by means of the adhesive l9, and to the outside of the plate by means of the adhesive go after the plate has been used for the. normal purposes of eating, or the like, the outermost lamination M may be removed. by pulling the exposed tab 22 of the outer lamina; tion. The rim portion of the outer lamination is thus freed, and the lamination can be freed from the adhesive I!) by upward pull. will be understood that the adhesive l!) is of a character such as to only hold the variouslaminationsto gether and to the inside of the plate, and if {1437,

sired the adhesive I9 may be of the spot type than he rin t eith ve se a he e v l befe sleser bfid ods 9 1d. ans ither o? or me fi a be s s a d the vessel. fi d a er e usual nn'e f o china es l, e seve a aminail rQvid sanita nin iQr I e e W can e readil rem ve in suege n Wh n t ec me s 2 T e sev r e netions v he 019M r n ent ma e nd ay be appro riate y wrated to prov d a iapnearan'ee be mde teqd tha h e v ss l st e s ed e in wil nc ud ifr pa s lik rti es-Y tive rigidity and formed of a bottom wall and an upwardly flared side wall, a plurality of superposed fiexible sheets disposed in covering relation with respect to the upper faces of said bottom wall and said side wall and projecting over the marginal edge of said side wall for a substantial distance therebeneath, means adhesively securing the marginal edges of said sheets to each other and to thelower side of; said; side wall, and a tear stripcarried by eachsheetspacedffrom the marginal secured edge thereof; the marginal secured portion of a removed sheet remaining secured to an adjacent sheet when said tear strip has been pulled, each tear strip having one end free from its associated sheet thereby forming a tab, and a numeral impressed on each tab for identifying the associated sheet.
