VACUUM-PACKAGE APPARATUS.
Specification of Letters Patent.
Patented Oct. 10,1911.
Application filed Kay 12 1910. Serial No. 560,905. 7
To all whom it may concern:
Be it known that I, GRAY STAUNTON, a citizen of the United States, residin at Evanston, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Vacuum-Package Apparatus, of which the following'is a specification.
My invention relates to improvements in 10 vacuum package apparatus, and has for its general object to provide means for packing material in air-tight receptacles to bemaintained sealedjby preponderance of ,atmos phere pressure over a reduced pressure within the sealed receptacle.
' More particularly, one of th'eobjeets of my invention is to provide a vacuum package apparatus, so that the exhausting apparatus may create in an area local to. itself and the receptacle, an attenuated atmosphere', the cover of the receptacle, as a whole, being entirely inclosed within the area of the exhausting means, and receptacle, and free for bodily movement to permit egress of air from the receptacle mto the exhausting means, and to be sealed u on the receptacle by the pressure produce in the operation of exhausting the air, so that when the exhausting means has been operated and removed, the cover Wlll be maintained in sealing relation with the receptacle by the preponderance of normal atmosphere over the pressure of attenuated atmosphere within said receptacle. A further and more specific object of my invention is to provide in association with a suitable receptacle :1 pump of the character to be described which is especially adapted for exhausting relatively large mouthed re-- 40 ceptacles, such as fruit jars or tumblers, and to use the top or closure of such receptacle in conjunction therewith in lieu of a check valve, and thereby to avoid the necessity of perforating the top, or other wall of the receptacle, and placing a special check valve therein, to retain the atmosphere attenuation of the interior of such receptacle.
Other and further objects of my invention will become a l parent to persons skilled in the art from 1 consideration of the application, ta ken in connection with the drawing, whe 'ein- V v Figurell is an elevation, partly in section, of a fragment of a vessel to be exhausted with a closure overlying the mouth thereot showing the manner of applying the'pump;
Fig. 2 is a perspective view of the flexible pump end, with a portion broken away to show the grooves therein; Fig. 3 is a fragmentary section of the pump end' taken on l ne 3-3 of Fig. 2; and in all of the views the same reference charactersindicate corresponding parts. 1
My 'nvention is to be used for exhausting the gaseous content of a jar or other receptacle and sealing same, as a result of such exhaustion. In preserving fruit, or the like,
or oxygen from such packages. It is also desirable to seal the package securely in order to retain the package in its exhausted Wondition. By the practice of my invention the closure is securely held in place over the mouth of the jar, or package, by virtue of the difi'erence of atmosphere pressure without and within said jar or package.
5 isthe jar or package to be sealed, preferably composed of glass, provided with a glass cover or closure, 6. A circumferential shoulder is formed around and under the periphery of said cover, as at 7, around which is seated-a flexible, preferably rubber, ring, 8, preferably of triangular shape, in cross section. This feature of my invention is specifically disclosed and claimed in my Letters-Patent No. 835,166, dated November 6, 1906. In this case, however, the top is not perforated, and is not provided with a special sealing valve. The open end or cap, 9, is made of a material which is more or. less flexible, such as rubber.. It is designed to fit over the open end of the pump and to be such size as to conveniently envessel.
The pump 10 consists of an ordinary brass pump barrel, 11, piston, 12, piston rod, 13, and handle 14, provided on its lower end with the bead, 15. The cap, 9, consists of a boss part, 16, the disk part, 17, and the skirt part, 18. The hub 16 may be provided with which the head 15 passes when the cap is placed upon the end of the pump. rlctional engagement between the pump barrel tion "of the pump tends to produce a more intimate contact between the parts, but the head and cave provide a mechanical means for positively maintaining association of parts when the pump is not in use. The
it is desira-ble to extract and exclude the aircompass the outside surface of the jar or an interiorcircumferential groove, 19, into 11 and the boss 16 is sufficiently great to retain the structure 9 on, said pump, as the suchollow radial ribs, herein shown as four, 20,
21, 22, and 23, said ribs overlying or pan tially encompassing corresponding grooves as at 21 and 22. These radial grooves extend from the central boss to a circumferential groove, coextensive with an exterior circumferential rib, 24:, thus providing air passageways from the pump to the outside surface r ofthe closure, as clearly shown in Fig. 1.
The lower edge of the flexible skirt, 18, is provided with an interiorly' circumferentially extending bead, 25, which strengthens this part of the skirt and provides an accurate surface for contact with the side of the jar toprevent air leak when-the device is in operation.
To hold the upper part of the skirt, an open brass wire hoop, 27, not large enough to fill the groove, 24, may be placed therein.
Thisfeature, however, is not essential to the use and practice of theinvention, as the stiffer disk or plate 17 is sufficient for this purpose.
The use and operation of the device is as follows: After the receptacle 5, such as a preserve-containing jar or the like, has been filled to a greater or less degree, the topor closure 6 having thereon the packing ring, 8, is'placed over the mouth or opening of the jar. The exhaust pump, 10, with the cap 9, is applied -over the mouth of the jar, as shown in Fig. 1, so that the bead, 25, of the skirt, 18, makes contact with the sides of the jar. When the piston, 12, by means of the handle 14-, is raised, air is drawn from the interior of the jar, the top, 6, rising suiliciently for the air to pass out between the packing ring, 8, and the normally contacting surface of the jar. When the handle, l l, is depressed, the piston, 12, forces the air contained therein upon the top surface of the closure, 6, thereby firmly sealing it, and the air will escape from under the bead 25, of the skirt, 18, the latter yielding sufficiently to permit of separation to provide an opening for the passage of air.
In the operation of the exhaustion, the closure 6 acts as a check valve, and the skirt, by virtue of its elasticity separates from the side of the jar, due to the pressure of air from the interior, thus acting as an exhaust valve. 21, 22, and 23, are preferably made of material somewhat harder and less flexible than the skirt,'18, and boss, 16, so as to hold the device more positively in the desired shape to be quickly applied. The wire ring 27 may be used to supplement this efiect if desired. Either means may be separately The disk, 17, and ribs, 20,
used, or both means may be used if desired. The air passes from the center to the periphery of the disk -17, through the radial grooves provided under the radial ribs 20, 21, 22, and 23, and the circumferential rib 24.
The cap 9 is sufficiently elastic to permit the free movement of the closure 6 in its operation as a check valve.
Having thus described my invention, what I claim is:
1. The combination with a receptacle having a single opening, and an imperforate closure therefor, of an exhaust pump, and a valveless cap terminal secured to said pump, inclosing the receptacle closure and adapted to make air tight contact with the receptacle beyond said closure.
2.
