Application March 22, 1934, Serial No. 116,818

9 Claims.

My invention relates to sanitary attachment linings for bath-tubs, wash-basins and like containers, and it has for its object to provide an improved device of the character indicated.

It is also an object of this invention to provide a. strong, durable and eflicient attachment lining of the character indicated which can be folded or otherwise collapsed into a small bundle so that it may be conveniently stored or transported; which may be quickly, and securely fastened in operative position within a bath-tub or other container so that removed after use; which will be of comparatively inexpensive construction, and which, in. its best form, will provide an inconspicuous lining having a hard, non-fibrous, sanitary and attractively smooth glossy inner surface.

To these ends I have provided a lining attachment of the character described having the peculiar features of construction and operation set forth in the following description, the several novel features of the invention being separately pointed out and defined in the claims at the close thereof. 7

In the accompanying drawing':- Figurelisatopplanviewofaliningfora bath-tub, said lining being constructed in accordance with my invention.

Figure 2 is a longitudinalsectional view of a bath-tub provided with a fining like that of Fig. 1. Figure 3 is an enlarged sectional view of one "end portion of the lining illustrated in Figs. 1

and 2.

Figure 4 is of Fig. 3.

Figure 5 is a detail hereinafter referred to. The embodiment of my invention herein illustrated is a complete, self contained lining structure for a bath-tub, said structure comprising a vessel-like container of thin flexible sheet material that is indicated generally at and which is of a size and shape to fit and coverthe interior portion thereof. The vessel-like container 10 is constructed with a bottom 12 to fit against the bottom of the tub; with oppositely disposed side walls 13 and 14 to fit against the opposite side walls of the tub, and with oppositely disposed endwalls 15 and 16 to fit against the end walls of the tub.

The bottom wall 12 is made, wall 15, with an an enlarged section on line 4-4 adjacent to the end outlet aperture 1'1 that is normally closed by a cover or closure element 18 of thin flexible sheet material adhesively and lyfastenedtothetopsideofwall 12in position to cover and closure element 18 is made at one side thereof that is farthest from the end wall 15 with an integral tang extension .19 which extends upwardly from said closure element to the upper it may be quickly detached and I of a bath-tub 11, particularly the lower closetheoutlet 1'1. This.

portion of end wall 15 where it is cemented or otherwise fastened to the inner side of said wall as at 20.

The outlet 1'! in bottom wall 12 is located so that when the lining is in position within the tub 11 said outlet is in register with the usual outlet 21 of the tub.

It is a feature of this invention that the exterior of the vessel-like lining is adhesively engaged with the surface of the tub so thatit will be maintained in extended vessel-like shape while in use. This engagement may be established by the employment in any suitable manner of an adhesive or cement. I

In the best form of my invention however. I provide a plurality of adhesive plaster patches 22 each of which consists of a small piece of textile fabric 23 having a coating of adhesive 24. In practice I have employed patches 22 made from ordinary surgeons adhesive plaster comprising a textile fabric body 23 coated upon one side with a waterproof adhesive composition 24-including rubber, pitch, and gums, as usual, and which will adhere strongly to any surface without setting or curing so that it can be quickly and cleanly removed or strippedfrom said surface y when desired.

Each patch 22 is permanently mounted upon the inside of the vessel-like lining 10 opposite, or in register with, an aperture 25 formed in the lining.

Each aperture 25 is of non-angular, or circular, shape and is located within the top marginal portion of the lining adjacent to the chime or upper edge thereof. The several apertures 25 are located at intervals throughout the circuit of the lining and as will layer of each patch is exposed upon the exterior of the lining by its aperture 25. The area of the aperture 25 -is substantially less than tlie area of that portion of the patch which is adhesively' engaged with the wall of the lining so that the latter portion materially reinforces the lining material immediately adjacent to and surrounding the aperture.

These exposed portions of adhesive material may adhere to other portions of the lining while the latter is collapsed in the form of a bundle or package while in storage or transit but may be readily disengaged when the lining is opened up for use.

When the liningistobe useditis opened and placed within the tub so that its bottom rests on the bottom of the tub and its upright walls are against the walls of the tub. Then by applying fingerpressuretothemiddle of eachpatchthe adhesive of the latter is shoved into its aperture 25 and against the proximate wall of the tub to which it Afterusingthetubewiththelininginposimovements of tion therein the bather pulls upwardly upon the tang extension 19 and strips the closure element 18 off from the bottom 12 whereupon the contents of the tub and lining discharge by gravity through the outlets 17 and 21 after which the lining is stripped fromthe walls of the tub and removed.

The embodiment of my invention herein illustrated has its end wall 16 constructed at its top with an apron extension 26 made near its extremity with apertures 27 and provided with patches 28 attached to the top surface of the extension, each opposite one of said apertures. By means of these patches- 28 the upper end of the extension 26 is adhesively attached to the top of the tub to hold the end wall 16 against being displaced downwardly through movement of the bathers body against the same.

It is an important feature of my invention that the; vessel-like lining attachment herein illustrated, with the exception of the adhesive patches 22 and 28, is made from a thin cellulose material such as that which is known commercially as cellophane. This cellulose material is of great tensile strength; it is nonfibrous; it has a desirably hard, smooth glossy surface, and may be colorless and transparent so that it is not conspicuous.

An advantage to the use of this material is that the lining is not easily displaced through the body of the bather while the latter is within the tub. Another advantage is that after use, and before removal of the lining the latter may, if desired, be quickly cleaned by rinsing or flushing so that, if desired, it may be used more than once although low cost of production permits of discarding the same after one use and for sanitary reasons this may be done., Its use will prevent the spread of disease in hotels and other public places where the bath tubs and wash basins are used by many diiferent people.

My new lining attachment may be produced in various sizes and shapes appropriate to the bathing container in connection with which they are to be used and therefore the invention is notlimited to the particular embodiment herein shown.

Also the vessel-like structure of the attachment may be made from a single piece of sheet material or from two or more pieces fastened tov gether.
