` VACUUM-Berrie CASE. j

Application mea october so, 1924. serial no. 746.831.

My invention relates to certain new and useful improvements in vacuum ibottle cases and it particularly has for" its object to provide means preventingliquid getting down in between the glass bottle and the'metal case. I-Ieretofore in vacuum bottles of the type now commonly found on the market, the glass bottle is held within a metalli(` casel by means of a spring cradle. that holds the glass bottle from breaking nythin the container andrkeeps it spaced froii'i 'the walls thereof, a rubber gasket being used at the mouth of the container and bottle to make a seal, with a view of preventing liquid working down, between the glass bottle and the case. This gasket, however, frequently rots.

'E plaster' of Paris, or other suitable material,

that will lill the space between the metal container and the elastic envelope and effect a permanent seal at the mouth of theglass vessel and that of the container.

In its more detail nature, the invention resides in those novel details of 'construction, combination and arrangementl of parts, all 0f which will be first `fully described, then be specifically pointed out in the afppended claims and illustrated in the accompanying drawing, in which:

Figure 1 is a vertical longitudinal section of a vacuum bottle container, the lvacuum bottle being shown in elevation, parts of the elastic envelope also' being shown in elevation, and other parts in section."

Figure 2 is a horizontal section on the line 2 2 of Figure 1.

In the drawing, in which likenumerals indicate like parts in all of the figures,` 1 is the glass vessel 'or vacuum bottle proper which is of the ordinary construction and -lis the container which also is of the ordi` nary constll'nction. In carrying' out my invention. I provide an elastic envelope 2 for the bottle* 1 which preferably does not extend entirely to the mouth of the bottle but leaves the neck ot the bottle projecting, from the envelope slightly. .The envelope raap le of any desired thicknessoi' material and .n.uinufactured in any desired way, its function being to allow for inequalities inthe expansion of the glass of the bottle andthat or' :he filling 3.. After supplying the bottle with the envelope 2, it is assembled in its case and plaster' of Paris or other suitablefilling material is poured in to set and occupy the space between the case 2l and the bottle and the envelope 9.l and to form a permanent 'seal around the mouth ot' the containerand ot the bottle. This liller also serves to prevent the bottle being broken by movement within the container. It' the bottle should become broken in any way and requires renewal, the plaster of` Paris can be broken away and the case used again, if desired.

From the loregoing description, vtaken in connection with the accompanying drawing, it 1s thought the complete construction, usesv and advantages of my invention will `be readily understood by those skilled'in the art. to which the invention relates.

l/Vhat Iclaim is:

1. In vacuumbottles, the combination with the glass bottle proper and the metallic case for cortaining the same, of an elastic envelope for the bottle and an impervious rigid filler between the envelope and the Acase said filler embedding permanently the elastic envelope and the glass bottle. n

. 2. In vacuum bottles, the combination with the glass:bottle and the metallic case surrounding the same, of an elastic envelope for the bottle and an inelastic filler between the envelope and the case land sealing the space between the case and the mouth of the bottle.

3. In vacuum bottles', the combination with the glass bottle and the metallic casethere Vttor, of a rubber envelope fort-he bottle and a plaster of Paris filler occupying the space between the Wall of the casey` and the envelope and bottle.
