or container so as to'exert such pressureon the security in holding the cap-tothe container and' 55 yet facilitating removal of the cap when desired while at the same time reducing the cost of production and also providing a cap affording to a practical degree a resealing cap in use after the initial removal of the cap. The cap 2 is formed with a depending skirt or apron 4 made with vertically extending flutings or corrugations 5 and also formed at its perimeter, or substantially thereat, with a groove or recess 6 designed to receive and ,hold the upper portion of an annular or ring-shaped elastic gasket 3, the outer face of which lies parallel with the inner face of the depending corrugated skirt 4 and its inner face adapted to make sealing contact with the outer surface of the wall of the container while the under surface of the centrally disposed top of the cap will rest or seat upon the top edge of the container wall all as illustrated. When the cap and its gasket is rst slipped over the open mouth of the container, the depending skirt or apron by means of a suitable tool or former, is pressed inwardly on a downward inclination or taper so as to make sealing contact with the outer surface of the Wall of the container, changing the outlines of the depending skirt and gasket from what is shown in Figs. 3, 5, 8, and l2 to that shown in Figs. 4, 6, 9, l1 and 13 respectively, and causing the inner face of the gasket to conform to irregularities in theiouter surface of the wall of the container and enterand practically close cavities otherwise existingbetween the wall of the container and the inner surface of the gasket, and making an effective seal between the cap and containenas illustrated in Figs.'4, 6, 9, 11 and 13 of thedrawings. The vertical corrugations give a degree of` elasticity to the skirt or apron in application and removal of the cap from the container and maintain the uniformity of contour of the skirt orapron throughout its circumference so that the effective seal is not impaired, whether the contents of the container have been subjected to a. processingtreatment as commonly practiced in the hermetic sealing of the contents of a container, or not so processed. 'Ihe vertical corrugations to the skirt or apron, under the present invention, perform the additional and important function of permitting the insertion, by a housewife, of a pointed instrument, for instance a needle like article, .between the gasket and wall of the container opposite the depressed portion Y of oneof the 'corrugations so that the face of the gasket at the point of application of the pointed instrument rwill be pressed away from the wall of theJ container and into a corrugation of the cap skirt and thus provide a vent leading to the interlor of the container at the temporarily displaced portion of the gasket away from the wall of thereceptacle and break the vacuum inthe receptacle and thus facilitate the removal of the cap without damage` to the cap or its sealing gasket. The corrugations also under normal con- Aditions serve to admit atmosphere between the gasket and skirt so as to exert an inwardly atmospheric pressure on the gasket in the direction of the wall of the container so as to press the gasket-against the wall of the container and tend to maintain sealing contact between the gasket and Wall of the container as previously stated.

Figs; 4, 6, 9, l1 and 13 show the relationship between the cap and its gasket and the container under acondition of vacuum in the container and the othergures without such vacuum. n In Figs. 8, 9, l0 and 1l the cap is shown formed withga depressedbead T adapted to seat against the rounded/.top edge ofthe wall of the tumbler or container, and the elastic gasket will be forced beneath the bead and close the space between the bead and outside of the container wall when the cap apron or skirt is given its downward and inward inclination as illustrated in Figs. 9, 1l and 13. In Figures 12 and 13 the container or jar I is shown as formed with an inclined face 8 at the outer surface of the wall substantially at the top and with a shoulder 9 below the inclined face so that the rubber gasket when compressed to sealing position will contact with the inclined face and also lie beneath the shoulder 9 thus making an eiective seal at said points and aid in holding the cap to its closing position.

It will be observed that in each form, the elastic gasket is shown as extending below the bottom edge of the depending skirt or apron. That is for the purpose of protecting or guarding the lingers or hand of the housewife, or manipulator, from possible injury by contacting with the edge of the skirt in lifting the cap from off the container.

I have illustrated and described the details of the several modifications but changes may be made therein and essential features of the invention retained as sought to be defined by the appended claims.

Having described my invention and set forth its merits what I claim is:-

1. A closure for receptacles comprising a cap having a depending skirt formed with axially disposed corrugations and an elastic gasket positioned between the skirt and wall of the receptacle and of a cross sectional thickness not to fill the skirt corrugations, the skirt extending downwardly and inwardly to effect sealing contact between the gasket and receptacle.

2. A closure for receptacles comprising a cap having a depending skirt formed with axially disposed corrugations, and an elastic gasket positioned between the skirt and receptacle and of a cross sectional thickness not to fill the skirt corrugations, with its upper portion in contact with the inner face of the cap, the skirt extending downwardly and inwardly to effect sealing contact between the gasket, receptacle and cap.

3. A closure for receptacles comprising a cap having a depending skirt, and an elastic gasket lying between the skirt and receptacle, the meeting faces of the skirt and gasket being so shaped as to form axially extending air spaces between the gasket and skirt to provide for atmospheric pressure' against the gasket in effecting sealing contact between the gasket and receptacle, the skirt extending downwardly and inwardly to effect sealing contact between the gasket and receptacle.

4. A closure for receptacles comprising a cap having a depending skirt formed with axially disposed corrugations, and an elastic gasket positioned between the skirt and receptacle, the skirt extending downwardly and inwardly to effect sealing contact between the gasket and receptacle, the corrugations serving to-receive a portion of the gasket displaced by a tool inserted between the gasket and wall of the receptacle to effect a vent to relieve a vacuum within the receptacle to facilitate removal of the cap.

`5. A closure for receptacles comprising a cap having a depending skirt formed with axially disposed corrugations, and an elastic gasket positioned between the skirt and receptacle and of a cross sectional thickness not to fill the skirt corrugations, the skirt extending downwardly and inwardly to effect sealing contact between the elastic gasket and receptacle, apices of the corrugations making sealing i contact with the elastic gasket, and the spaces between the apices constituting cavities serving to receive atmospheric pressure between the skirt and gasket to exert pressure on the gasket in direction of the wall of the receptacle to effect sealing Contact of the gasket with the wall of the receptacle.v

6. A. closure for receptacles comprising a cap having a depending skirt formedv with axially disposed corrugations, and an elastic gasket plositioned between the skirt and receptacle, and of a cross sectional thickness not to ll the skirt corrugations, the skirt extending downwardly and inwardly to effect sealing contact between the gasket and receptacle, the gasket. being also extended below the lower edge of the skirt prior to application of the closure and subsequent tok its removal to afford a safety guard for the hand in manipulation of the cap.

7. A closure for receptacles comprising a capv having a depending skirt formed with axially extending corrugations and with a groove in the v `face disposed for Contact with the inner apices of the skirt oorrugations, the corrugated skirt extending downwardly and inwardly to effect sealing contact between the gasket and cap and a receptacle to which the cap is applied.
