Description
April 15, 1930. 5 STANLEY CLOSURE FOR BOTTLES OR BAGS Filed April ll, 1928 Y E N R O T T A Banan s, 1930 STANLEY .1. summit, on new Yoax, n. v.
CLOSURE FOB "BOTTLES OR BAGS Application filed April 11, 1928. Serial No. 269,079.
This invention relates to closures for bottles or bags, and for use particularly in connection with hot water bottles or ice caps or bags.
The stopper or closure of the present invention is designed particularly foruse in connection with the gasket disclosed in my Patent No.1,640,430, granted July 30, 1927.
The gasket described in that patent has been found ineffectual to prevent small leaks where the ordinary screw top closure has been employed, and it is to overcome such defect that the resent cap is designed. V v
A furt er object of the invention is to pro-' vide a cap constructed in such manner and of such materials as to obviate the possibility of leakage occurring at the mouth of the neck when used with any compressible washer 0r gasket other than the type disclosed in the aforementioned patent. v
2 A further object is to provide a cap or closure constructed in such manner as to minimize the degree'of air-pressure at the threads or at other points Where leaks usually occur when the bag is under pressure or in compressed condition.
With these objects in view, together with others which will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts, all as will be disclosed more fully hereinafter, illustrated in the accompanying drawings and particularly pointed out in the claims.
In the drawings:
85 Fig. 1 is a erspective view of a conventional form of ice cap and illustrating the application thereto of a cap embodying the invention,
V Fig. 2 is anenlarged fragmentary sectional view taken through the neck of the ice cap and illustrating the closure and gasket in operative position,
Fig. 3 is a bottom plan view of the improved cap, and
Fig. 4 is a longitudinal sectional view taken through the gasketpreferably used in connection with the improved cap.
In hot water bags, ice caps and other containers of a similar nature usually employed in or ab u the sick room, it has been f und difiicult to preventleakage to some degree around the closure. Leakage usually occurs when pressure is applied to a bag filled or partly filled with water mice, as the external pressure displaces the fluid into the neck and against the threads of the stopper and out between the shoulder of the stopper'and the gasket. This leakage is particularly noticeable in instances where the ordinary screw top of metal is used, due to the fact that it is practically impossible to compress the rubber gasket between the neck and the metal top sufficiently tight to hermetically seal the container.
I have found that this difliculty or objection is overcome b the use of a sto er or closure constructe in accordance w1t this invention, and this is due to the fact particularly that the material of which the stopper is made has a decided aflinity for rubber and forms a strong union therewith, and also due to the fact that provision is' made in the stopper for entrapped air which may be ac commodated and permitted to com ress, thus reducing the degree of pressure at t e threads or at the juncture of the cap shoulder with the gasket.
In carrying out the invention, the cap, represented generally at 5, is formed of a su stance or material impregnated ,with orpossessing a hard resin which has a strong aflinity'for rubber and when tightly engaged therewith forms a hermetically sealed joint.
This material is known as Micarta, and so far as I am aware has never heretofore been used for the purposes here employed.
The cap 5 includes a tubular body portion 6 of a depth substantially equal to the height of the bottle or bag neck 7,. and is provided in its exterior surface with a thread 8 corresponding to threads 9 in the metallic neck 7. The body is provided at its outer end with an outwardly directed annular flange 10,. the under surface of which, in practice, is disposed parallel to the outwardly-extending flange 11 of the bottle or bag neck. The shoulder thus formed by the outwardly projecting annular portion v10 engages the gasket 12, formed preferably of rubber and the passage of air or liquid. The under surface of the shoulder 10 may be provided with annular ribs 13 to engage with the gasket and form additional obstructions for the passage of air or liquid. v
As before stated, the use of Micarta, possessing resin, causes such gripping actionbetween the rubber gasket and itself as to create a union preventing the passage of fluid or air, even though the ba or container be subjected to a relatively hig degree of pressure. To relieve the threads and the union thus formed, however, of some of this pressure, the cap is constructed in such way as to provide an air chamber in order that air entrap ed within the bag may be accommodated an permitted to contract without creating excessive pres sure at points where leakages might even tually occur. The body 6 of the cap is of substantially tubular formation and the skirt portion thereof is of a length substantially equal to the height of the neck. 'This body portion is hollowed out to provide a pocket 14, closed at its upper end by the head or portion 5, but open at its inner end to at all times be in communication with the interior of the bag. By constructing the body of the stopper in this manner it is at once'apparent that the pocket l-provides a chamber in which air or liquid may enter when compression of the bag occurs, so that the internal pressure at ints where leakage might occur is considera ly reduced.
It has been found in practice that a cap or closure for ice or hot water bags constructed of the material mentioned and in the manner disclosed efiectively accomplishes the object set forth where caps similarly constructed but formed of different materials have been unable to accomplish the desired results. The
sealing of the joint between the gasket and the shoulder in air and water tight connection is attributable to the material of which the cap is formed and the peculiar under surface of the shoulder which comes in direct contact with and compresses the gasket.
Having thus described my invention, I claim: 1. In a stopper for bottle necks, a neck havmg internal threads and an outwardly directed flange at its outer end, a stopper c0mprismg an exteriorly threaded body formed of a material including hard resin, an outwardly extending shoulder at the outer end of said body, a rubber gasket interposed between and shoulder, and the said neck and stopper provided withmeans for bringing the shoulder forcibly against said asket.
3. In a closure for bott e necks, a neck having an out-turned flange formed of metal, a stopper for said neck, a shoulder projectin outwardly from said stopper to overlie sai flange, said shoulder formed of material including hard resin, and having a strong aflinity for rubber, a soft rubber gasket interposed between said flange and shoulder and the said neck and stopper provided with means for brixllging the shoulder forcibly against said gas et.
In testimony-whereof I hereby aflix my sig nature.
STANLEY J. STANLEY.
