i Application filed August 21, 1916. Serial N o. 116,007.

To all whom t 'may concern.'

i Be it known that I, BAsiL SAvAGE, a citi- `zen of the United States, residing at San- Diego, in the county of San Diego and State 0f California, have invented new and useful Improvements in Receptacles and Closures Therefor, of which the following is a specication.

This invention relates to receptacles and closures therefor, and more particularly to preserving jars and closures therefor, such invention having for its object the provision of an improved organization or combination or association of parts and features which will be superior in point of relative sim@ plicity and ineXpensiveness of formationf construction and organization, taken in con-- nection with positiveness in action, facility 1n application, manipulation and use, effectiveness in 4sealing function, which will permit the ar or other receptacle readily and conveniently to be unsealed or opened, and

which may be conveniently utilized within its structural organization for indicating the contents of the closure, and which will be generally superior in efficiency and serviceability.

With the above and other objects in View, the invention consists in the-novel and useful provision, formation, combination, association, mode of application and inter-rela- A'tion of parts, members and features, all as 1 hereinafter described, shown in the draw- 'ing and nally pointed out in claims. 3E In the drawing:

Figure 1 is a central Vertical sectional View of a fragment of a container, shown as a bottle or preserving jar, the improved closure for which and means of sealing which are shown similarly sectioned and applied to the oriice of such receptacle; Aand F ig. 2 isa detail transverse sectional view of the same, taken upon the line 2-2, Fig. l, and looking in the direction of the appended arrows, t

Corresponding parts 1n both figures are designated by the same reference characters.

Referrin with particularity to the drawing, A designates the upper or mouth portion of a preserving jar or bottle, and B designates inclusively the closure and sealing means shown as applied to such jar or receptacle, which latter is formed or provided adjacent to its oriticeand upon the exterior wall with screw threads 3 adapted to coperate with similar screw threads 4r formed upon the cap element a of the sealing and closure means B. The orifice of the jai' A is formed or provided at its terminal portion with an annular seat 5, produced by beveling or chamfering ofi the wall of the mouth portion of the receptacle, to produce an outward and upward flare, and a sealing element b in the nature of an annular gasket cooperatesl witlrand is applied to said seat, being -held thereto `by the cap element a and a disk element c interposed between such cap element and such sealing element. Preferably suc'h cap element a is provided with a central or -bodv receptacle, and having an annular depending flange portion 7' in which or upon which the threads 4 are formed, such threads being preferably produced by distorting or striking up the metal of such capmember in any suitable manner. The disk element c, which may be referred to specically as the lid, while the cap member a may be referred to generally as a screw cap, is suitably formed or pressed into shape from a blank of cardboard, and the sealing element may be of any suitable material, such as rubber, or a` plastic composition, being compressible to produce a liquid-and-air-tight joint as between the lid and the mouth portion of the receptacle when said sealing element and lid are jointly forced into position by application of the screw cap over the same and in threaded co-action with the threads 3 upon the receptacle mouth wall. To produce a particularly eflicient closure and sealing relation, and to most eiectively take advantage of the flaring seat 5 for the sealing element b, such sealing element is likewise dished in formation or caused to flare upwardly and outwardly in its annular con-struction, so as to complement such formation of the seat 5; and likewise the cardboard lid c is bent upwardly and curved outwardly and slightly downwardly, as at 8, to overlie the sealing element or gasket b and come substantially into contact with the upper region'of the hseat 5. To accommodate such inter-relation of the marginal portion of the lid c and the sealing element or gasket 5, the marginal portion of the body 6 of the screw cap a is likewise upwardly and outwardly bent, as at 9, thence depending to produce the threaded flange 7. The

portion 6 fitting over the entire orifice of the body portion 6 of the screw cap may be slightly upwardly arched the more effectively to withstand atmospheric pressure resulting from the sealing off of the contents of the closure partially n ocwo, and the central portion of the cardboard lid c may likewise and correspondingly be upwardly arched beneath such central or body portion of the screw cap.

In the application of the closure and sealing means B to the 'mouth portion A of the jar or other receptacle, the sealing element or gasket b is first applied or attached to the cardboard lid, and suitable conditions prior to sealing off the contents of the Jar having been created within the jar, thc said sealing element and lid are jointly applied to the sealing element Seat 5, and the screw cap is then screwed down over such elements, so as to force the lid tightly against the sealing element and the sealing element tightly against its seat, the wedge action resultant upon depression of the sealing element in the flaring seat producing a particularly tight and efficient sealing action. Prior to the application of the screw cap a there may be inscribed upon the upper surface of the cardboard lid c a suitable mark, symbol or wording indicative of the'character and nature of the contents ofthe jar, sovfthat ".when the screw cap is afterward removed the contents of the jar ma be known with citt removing the lid. an sealing element an""=`making examination of such contents. Whenlit is desired to remove the contents of the jar, the screw cap is un'screwed and the lid is punctured, if held in position by atmospheric pressure incident to partial vacuum in the jar. This puncturing may readily be performed due to the cardboard material of the lid, and thus the unsealing of the jar is rendered far more easy and conif'enient' than when a metallic lid isemployed. After such puncturing the lid and the sealing element or gasket b may be removed, and the contents of the jar taken therefrom. The Sealing elexpent effectively isolates the contents of the ]ar from the metallic screw cap a, preventing contamination of the substance of the jar or any poisonous or deleterious effect upon such contents being produced.

It will be seen that the entire closure and sealing means may be very cheaply produced, are convenient in application and removal and in use, effectively seal off and inclose the contents of the jar, and provide for coiwenient indication upon the lid of the contents of the jar, at the same time being sanitary and safe in use, theonly portions of such closure and sealing means being exposed to the contents of the jar consisting of the non-metallic sealing element and lid.

While l am aware of the fact that many devices and combinations and associations of parts and features have been devised aiming at the proper sealing and closing off of the contents of jars and other receptacles, I am not aware, after extendedl examination of such prior means, that any combination, inter-relation and association of parts and elements as shown in the drawing hereinabove described have previously been devised, nor the particular inter-relation of the same with the orifice of the receptacle, the distinguishing advantages and benefits and attributes of efficiency 'and convenience attaching thereunto readily appearing from the foregoing description vtaken in connection with the drawing. Y

I do not desire that the combination be understood as limited to the specific provitures herein-above set forth and shown in the drawing, but wish to point out that many detail departures may be made from lthe same, without circumventing-the spirit and substance of the invention.

Having thus disclosed my invention, l claim and desire to secure by Letters Patent:
