Application June 18, 1941, Serial No. 398,681

4 Claims. 1

This application is a continuation in part of aggication Serial No. 251,312, filed January 17 1 I My invention relates to a new and improved combination of a, receptacle and a closure therefor. a

One of the objects of the invention is to provide a cap for glass jars, bottles or the like which are sealed under vacuum, whereby the vacuum can be readily broken without distorting the cap to any substantial extent and without chipping the glass,'and whereby the cap can be used for sealing the contents after the vacuum has been broken. g

Another object is to provide simple means which can be manufactured at low cost and which can be used in a simple and convenient manner. I

More particularly the invention embodies a combined glass container and metallic closing cap so. arranged and constructed that with the ordinary conventional kitchen tools the housewife may break the vacuum to remove the cap without chipping the glass and with the greatest facility, while the cap may be re-inserted to form a substantially tight closure notwithstanding the vacuum-breaking and cap-removing operation.

Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above statement of the objects of my invention is intended generally to explain the same without limiting it in any manner.

Fig. 1A is a plan view of the invention;

Fig. 2A is a section along the line 2A of Fig. 1A;

Fig. 3A is a section along the line 3A of Fig. 1A;

Fig. 4A is a side view with parts broken away;

Fig. 5A is a view of the embodiment of Figs. 1A to 4A illustrating the relative rotation after the vacuum is broken; and

Fig. 6A is a perspective view showing the breaking of the vacuum by the use of an instrument T.

Closures for glass receptacles utilized in the marketing of food products have heretofore been proposed wherein means are provided for facilitating the removal of the closure cap. These proposals usually involve the. use of a sharp or other tool for prying off the cap, and in allsuch prior proposals with which I am familiar the construction is such as to necessitate the tool coming. into chipping contact with the glass with the attendant danger of glass chips entering the food product, or no provision is made to mini mize or obviate this danger. 1

This invention relates to. food container closures, particularly adapted for vacuum packed food products, and takes into account the danger of glass chipping by the. closure removing tool and minimizes or entirely obviates this'danger. It furtherinvolves the permanent upsetting or mutilation of a part of the closure for the purpose of breaking the vacuum preliminary to removin the closure with provision for reclosure after the removal to prevent or-reduce the likelihood of contamination of food remaining in the container. -1

Referring to Figs. 1A to 6A of the drawings,

the invention is illustrated as embodied in a glass jarJ' whose neck or mouth portion l' is indicated as having the finish illustrated, being of conventionalstructure. According to this conventional structure the upper or end periph- I eral edge of the neck portion is indicated as having a central substantially flat portion and the rounded edges l1 and J8. The peripheral edge I! merges into a substantially flat outside surface and this merges-into a-rounded holding surface or shoulder 20. Thejar is provided onits end peripheral edge, with shallow lateral recesses 4', the sides of these recesses being curved;

as indicated at l5 and It. In the particular embodiment shown there are four of these recesses 4, and this is the preferable number forthe reasons indicated below. These recesses are comparatively shallow and are exaggerated in depth as shown in the drawings to correspond to the enlarged scale of the drawings.

The closure includes a metallic cap having a disc or bottom 5 and an annular flange I2 formed integral therewith, the flange engaging the flat side periphery of the neck of thejar or container. The lower part iii of the flange .I2 is curved inwardly to engage the rounded holding surfaceor shoulder 20 formed in the glass container and the edge of the flange is formed into a reinforcing bead l4. The closure also includes a sealing composition 2| which according to conventional practice may be fixed to and carried by the closing cap. This seal may be of composition paper or composition rubber or composition cork and is compressed tightly between the end peripheral edge of the neck I of the glass jar and thedisc 5' of the cap. Under the pressure of the closure and due to the nature of the sealing composition the latter completely fills up thelateral recesses! formed on the end peripheral edge of the jar. As indicated any suitable. composition may be emsealing compound or composition 2| containedin the recesses 4'. As indicated in the drawing, the lower wall of a slot 9' is disposed above the level of the bottom of the recesses 4' and likewise the upper wall of the slots 9 is spaced below the disc 5'. Similarly, the end Walls of the slots 9 preferably stop short of the end walls I5, iii of therecesses 4'. These slots 9' serve the double function as indicia to indicate tothe housewife Where an instrument T, such as an ordinary kitchen knife, may be inserted to break the vacuum in the container and remove the closing cap, and also function to accommodate the reception of this instrument, This instrument T is' inserted through, the indicium slot 9' and the sealing ,composition 2| contained in the recess 4 is pierced by this instrument .to break the vacuum, where- 'fuponthe instrumentor knife T may be lifted as indicatedein Fig. 6A with thecomposition in the bottom of recess dforming a fulcrum to pry the side'of'the'closurecap with the flange l3 disengaged from the holdingsurfaceZD; By reason of the arrangement and structure shown the vacuum may be broken and the cap removed without the knife engaging the glass walls of the lateral recess 4,-. thus completely eliminating the danger of chippingofl glass particles from the glass during this operation. 13y providing amultiplicity of these lateral recesses and'co-operating slots 9 ,the housewife may insert the knife T into each of these-slots and through 'the composition contained'in each of-the recesses 4' and the cap is thereby'pr'ied off gradually without distorting the same. v p 3 After the vacuum is broken and the cap re-' moved the housewife may readily replace the cap upon the jar'and reclose' the same, and a sub- 'stantially' tight closure is obtained notwithstanding the puncture of the sealing compound in alinement with the slots 9, since upon replacement the cap is rotated as indicated in Fig. 5A relatively 1 to the jar with theslots 9 out of alignment with therecesses 4'. The jar neck as shown in the drawings is not provided with a bead below the holding shoulder 20, but it isunderstood that it may be so provided with the conventional bead. A sharp round instrument may be utilized in the place of the knife'T, but a fiat instrument is preferable with a sharp point. The reclosing may be assisted by reheating the product and creating a slight vacuum inside the container whereupon with the cap in the position shown in Fig. 5A the holding and closure is assisted by the atmospheric pressure. It is understood that while the indicium slots 9' are indicated as elongated, slots of any suitable character may be substituted thercfon.
