VACUUM-COVER FOB, RECEIPTACLES.
Specification of Letters Patent.
Patented Apr. 8, 1919.
Application filed January 10, 1918. Serial No. 211,247.
'To all whom it'may concern:
and useful Improvements in Vacuum-Covers for Receptacles, of which the following is a specification. j
This invention relates ,to vacuum covers for receptacles, and has for its primary object to provide improved means for hermetically sealing the container and preventing heat or cold passing through the said;cover.
A further object of the invention is to provide a. cover adapted particularly tor-use in connectoin with vacuum containers or receptacles, and includes a novel means for assembling the cover with the receptacle in such manner as to obviate the possibility of the cover becoming readily detached from the container. as well as to prevent heat or cold entering or leaving the container through or around the cover.
\Vith these objects in view together with others which will appear as the description proceeds the invention resides in the novel formation. combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims.
In the drawings l igure 1 is a vertical sectional view taken through a conventional form of vacuum avall container, and illustrating the application of a cover constructed in accordance with the invention,
Fig. 2 a bottom plan view of the improved cover, and,
Fig. 3 is a sectional view taken on line 3-4-3 of Fig. 1.
Referring now to the drawings, 4 indicates generally the body of the receptacle with which the improved cover is used, and this receptacle is provided with a second or inner wall fispaced from the outer wall. Lugs (3 maintain the inner and outer walls in proper spaced relation, so as to provide a' coiuparl ment completely surrounding the inner wall. A nipple 7 may be arranged in the outer wall and preferably at the bottom thereof. and through which the air within the chamber between the walls may be extracted. The nipple 7 is made of soft metal such as lead. or con'iposition of lead and tin.
so that the same may be squeezed together as indicated in the drawings after the air has been removed fromwithin the Walls of the vessel by a mercury. pump. This contraction of the nipple may be easily and quickly performed, and entrance of air through the nipple to the vacuum chamber is prevented.
The upper open end or mouth of the receptacle has its walls flared outwardly and the improved cover, indicated generally at 8, is adapted to fit within the open end of the receptacle and to snugly seat upon the inner wall 5 thereof.v The lower portion of the cover is therefore tapered, and a bottom 9 extends across the cover, remote from the lower end thereof. By so constructing the cover, the lower portion thereof constitutes an apron 10 which fits'snugly with the inner Wall 5 of the receptacle mouth.
The upper end of the cover protrudes bc yond the corresponding edges of receptacle, and the outer edges of the said cover are turned downwardly as at 11 to overhang the edges of the receptacle. A nipple 12, similar to nipple 7, is arranged in the bottom 9 of the cover, so as to enable the air within the hollow portion of the cover to be easily removed therefrom. It will be observed that the double wall'arrangement of the cover is included in the overhanging portions 11 thereof.
In applying the cover to the receptacle, a washer 13 is arranged around the cover 'between the body and the overhanging portion 11. The cover is then inserted in the upper open end of the receptacle, and the upper edge of the latter supports the said cover. The gasket 13 is interposed between the said upper edges and the cover and hermetically seals the container, and it is to be observed that the overhanging portions 11 extend downwardy a distance approximately equal to the horizontal plane of the upper edges of the receptacle mouth.
It is obvious that a receptacle and cover constructed in accordance with the torego-t ing lessens the liability of the temperature ticularly to be used' in connection with milk cans or containers, but it is to be understood that its use is not necessarily limited to containers of this character, as it will be readily 7 and the overlapping portions of said cover a parent that refrigerating plants, ice 0 ests and other receptacles where a con- "stem or unchanging temperature is required may egually as well be provided with such a coverm While the above is a description of the preterred embodiment of the invention, it will be understood that the invention is not necessarily limited to the structure shown and'described, as changes in the details of construction and arrangement of parts may be resorted to Without departing from the invention as defined by-the claims. I claim V 1. In a device of the class described, the combination with a container having spaced walls, of a cover for said container adapted to extend into'and to fit within the open end of said container and to extend beyond and to overlap the edges thereof, and the body comprising Walls spaced apart.
2. In a device of the class described, the combination with a container having spaced Walls, of a cover for said container adapted to fit within the open end of said container and to overhang the edges thereof, the body and overhanging portions of said cover comprising walls spaced apart, and a gasket intel-posed between said cover and the upper edges of said container.
'3. In a device of the class described, a container having spaced walls and being flared outwardly at its upper open end, a
hollow cover for said container adapted to extend downwardly into said open end and I In a device of the class described, a'
double walled body, a nipple comprising a tube communicating with the interior of the said body and being independent of the body, and the said nipple being formed of readily compressible material.
In testimony whereof I 'aiiix my signature in presence of two witnesses.
