JAR COVER Filed Oct. 6, 1953 Patented Nov. 12, 1935 V UNITED STATES JAR COVER Charles S. Baron, Tiffin, Ohio Application October 6, 1933, Serial No. 692,524 2 Claims. (01. 215-38) I as glass, earthen ware, or metal if desired. The

shape and configuration of the jar are susceptible of wide variation in respect to design and dimensions. The cover'may be solid, as for the confinement of liquid within the jar, or it may lbe foraminously perforate for use as a container for table service of pulverulent substances, such as salt, pepper, or spices.

The means for securing the cover to the jar are very simple, so as to render the jar and its cover easy to be effectively secured together for use, or to be separated upon occasion as required, by the simplest disjunctive manipulation, without the necessity for imparting to the respective members any relative motion by twisting or screwing movement of the two portions, which, when united, complete the container, such movement being sometimes difficult to effect.

In addition to the device comprising only a cover and jar, provision is made for the accommodation between them, in assembled union, of a liner, which may be made of any suitable elastic or semi-elastic yielding material, varying, for instance, from thin glazed paper or thicker cardboard to the more substantial thickness of a cork liner, which is especially adapted for hermetically sealing the complete container against leakage of liquid confined therein. The liner may be of disk shape, or for some purposes, it may be desirable to make it in the familiar shape of an annular gasket.

What constitutes my invention will be hereinafter described in detail and succinctly defined in the appended claims.

In the accompanying drawing which illustrates my invention in its present preferred form of embodiment,

Figure I is a diametrical vertical section of the neck of a jar and of its attached cover in one form of embodiment.

Figure II is a similar view showing a modification of the cover.

Figure III is a like view of a further modification illustrative of a disk shaped liner between the jar and cover.

' Figure IV is a View similar to those preceding,

showing a reversal between the connective ele- V ments on the jar and cover, respectively.

Figure V is a top view of the cover shown in Figure I, illustrating in broken line the expansibility of the cover by which the union and disunion between the jar and its cover are effected.

Figure VI is a top plan view of jar as shown in Figure I, with cover removed.

Referring to the numerals on the drawing, in which each part is designated by a distinctive 5 numeral, i indicates a hollow body which may be made of any suitable material, as aforesaid, and of any design and dimensions preferred. The dimension of the member I may vary from' the smallest size that may be desirable to sizes as large as four or five inches in the diameter of the neck 2 thereof.

In all dimensions of the member 8, the neck is provided substantiallyon opposite sides with a pair of latches 3 formed by any preferred method of the material of which the neck is composed.

I prefer to locate the latches upon the outside of the neck, but it is obvious that they may be located, mutatis mutandis, on theoutside'wall of the cap. When located on the outside of the neck, the cap or cover 4 is made as indicated in the drawing, to receive the neck within it; but

if the latches be located on the outer wall of the cap and the continuous flange be on the inside of the neck, the skirt of the cover becomes the male member and the neck the female.

I illustrate four forms of female covers, which respectively present advantages in design as well as in mechanical adaptation to the purpose intended. In Figure I for example, the cap 4 is shown in form preferred for solid caps, and which is sufiiciently constricted in diameter to define a shoulder 5 between the skirt 6 and the top I of the cap, that is adapted to press upon the mouth-defining rim 8 of the jar.

Figure II illustrates a similar form of cap which is preferred for a foraminous cover.

Figure III illustrates a form of cap especially adapted to accommodate within it the thickness of a liner 9 made of such substantial material as cork.

Figure II shows a cap which is distinguished by the presence of a dome-shaped top It). This form of cap is for some reasons superior to all others, but it requires that the rim 8 be extended sufficiently to find a seat directly against the lined inner face of the dome l9 instead of against the shoulder 5 that is provided in the other caps for such a seat.

Figure III shows a fiat topped cover specially adapted to accommodate a heavy liner 9, the rim 8 being omitted.

In Figure V, I show diagrammatically the oval or elongated form which the skirt 6 assumes in comparison with the normal cylindrical shape of the skirt as shown in said figure upon elongation thereof as by action of the latches 3, or by external pressure upon the skirt 6 which accomplishes the same effect.

In practice, all that is necessary to secure any form of cap to the body I is to force the cap gently into place against the resistance opposed by the presence of the latches 3. Thereupon the skirt assumes at first the elongated form shown in Figure V. The latches are usually located above the rim or annular projection 8 on the neck 2 and the faces of each are tapered from bottom to top as indicated by the numeral I4. Each is pro-- vided with an undercut recess l into which a projection IS on the skirt enters when the latter is forced into contact with the bead 8, the resiliency of the skirt causing the member [6 to snap into secure engagement with the'wall of V the recess and so to confine the cap to the body against accidental displacement in ordinary use.

As illustrated, the projection I6 is susceptible of' considerable modification of shape in cross-section. For effecting the greatest security of union between the jar and cover, the sharply deformed annular construction of the member I6, as shown, for example only, in Figure IV, is preferred.

As often as occasion may require, the cap may be pulled apart from the body by the gentle application of force which may be facilitated by pressure of thumb and finger applied to opposite sides of the outside of the skirt between the spaces which separate the latches.

What I claim is:

1. In combination with a container, of a deformable cap provided with a resilient circular shaped skirt arranged to detachably engage the container, said skirt being of a uniform depth and members thereby sprung outwardly sufliciently to ,clear the locking members so that the cap may be readily removed from the container upon the application of inward pressure to opposite sides of the skirt between said locking members.

2fIn combination with a container, of a deformable cap provided with a resilient circular shaped skirt arranged to detachably engage the container, said skirt being of a uniform depth and having an annular continuous inturned projection adjacent its bottom edge, said projection completely surrounding the container when the cap is applied, said container having a pair of diametrically opposed tapered latches, each latch being provided with an undercut recess for receiving the projections when the cap is applied to the container, said skirt being sufliciently spaced from the container between the latches to permit the portions of the skirt disposed between the latches to be pressed inwardly and the skirt portions opposite the latches thereby sprung outwardly sufiiciently to clear the latches whereby said cap may be readily removed from the container upon the application of inward pressure to opposite sides of the skirt between said latches.
