March 16 1926- C. HAMMER FRICTION TUMBLER CAP Filed 001:. 1, 1924 'yv w Patented Mar. 16, 1926.
UNITED STATES PATENT OFFICE.
CHARLES HAMMER, OF HOLLIS COURT BOULEVARD, NEW YORK, ASSIGNOR TO AMERI- CAN METAL CAP COMPANY, OF BROOKLYN, NEW YORK, A
YORK.
CORPORATION OF NEW FRICTION TUMBLER CAP.
To all whom it may concern:
Be it known that 1, CHARLES HAMMER, a citizen of the United States, residing at Hollis Court Boulevard, in the county of 6 Queens and State of New York, have invented certain new and useful Improvements in Friction Tumbler Caps, OfWlllCll the following is a specification.
This invention relates to metal caps, and
10 more particularly to what is known as a friction cap adapted for use on glass containers, suchas the tumbler or preserve Jar variety, the object of the invention being to provide an improved metal friction cap or closure which will eflectively seal the con tents of the container and will not prematurely jar off, but which can be readily removed when desired.
It is the present day custom of many ackers to pack the preserve tumblers or ars while the contents are hot, and as the caps, when applied, hermetically seal the container, those forms of friction caps heretofore used which did not permit the escape of the air resulted in t 1e blowing off of the caps when the tumblers or ars were packed hot.
Furthermore, the purchaser found it was a nuisance and very difficult to get off certain styles of these caps without either mutilating the cap or breaking the glass container, which latter was liable to result 1n part of the glass getting into the contents so that it had to be thrown away. One of the major defects of many friction caps heretofore atented, and particularly those having vertical holding corrugations, 13 that they fail to efficiently hold on to the container, so that they are prematurely 1arred or worked off.
The object of the present improvement ,therefore is to provide a friction cap which will avoid these defects, and will therefore efiiciently hold .on to the container both while the contents are being packed and subsequently, and yet can be readily removed without mutilation of the cap or jar.
In the drawings accompanying and forming a part of this specification, Fig. I is a perspective view of the cap; Fig. 2 is an enlarged transverse section through a concaved friction holding surface; Fig. 3 is an enlarged transverse section through the juncture point of a pair ofcon'caved friction holding surfaces; Fig. 4 is a. bottom view of the cap with liner partly broken away and illustrates'the concaved friction holding surfaces; Fig. 5 illustrates the cap applied to a tumbler; Fig. 6 is an enlarged diagrammatic view of a portion of the cap and container prior to the forcing on of the cap; and Fig. 7 is an enlarged view after the cap is forced on to the container, these two views illustrating the different positions of the concaved holding surfaces.
Similar characters of reference indicate corresponding parts in the several drawings.
Before explaining in detail the present improvement and mode of operation thereof. I desire to have it understood that the invention is not limited to the details of construction and arrangement of parts which areillustrated in the accompanying drawings since the invention is capable of other embodiments, and that the phraseology which I employ is for the purpose of description and not of limitation.
This improved metal friction cap or closure comprises a top 2 of any suitable form having a depressed panel 3 forming an annular reinforcing portion 4 around the top. This top is provided with a depending skirt or flange shown as of shallow form 5 whereby the cap is particularly adapted for use on a tumbler or jar, such as a preserve tumbler having a comparatively smooth cylindrical outer sealing surface near the top thereof. The lower edge of this skirt is reinforced or strengthened by rolling or curling or turning the metal of an annular band upon itself to form a bead or rolled edge 6 of comparatively small size. The top edge of the flange is also formed with an annular band 7 forming an annular recess 8 on the inside of the'cap for the reception of a suitable gasket or liner plate 9. Between this annular band 7 and the strengthened lower edge of the cap .is a series of concaved angularly connected surfaces 10, the inner convex faces 11 of which project interiorly of the flange or skirt, so that the concaved surfaces are at the outer side of the skirt. The diametrical distance apart of the convex faces of these friction holding surfaces is not reater and isusually slightly less than t e diameter of the sealing surface on the container; -1 These concaved friction surfaces are directly:.-united with each other end to end around the flange, and in one form shown are of greater circumferential width orlength than height, thus forming a continuous series of unseparated concaved surfaces entirely around the skirt, so that the angle or juncture points 12 form very small vertical ribs. These concaved surfaces as well as the juncture points thereof do not in the form shown project beyond the normal cylindrical surface of the skirt, and in the construction shown are contracted or narrower vertically at their middle than at their juncture points with the narrow vertical ribs. The concaved friction holding surfaces extend from near the top of the cap to near the strengthened lower edge, and therefore take up practically the entire skirt above the strengthened edge and are beveled upwardly on the inner side of the flange at the bottoms, as at 13, to facilitate the forcing of the cap on to the tumbler, so that the necessity of providing a cylindrical skirt portion below the friction holding surfaces is avoided.
Thus the friction cap has the skirt made up of a continuous series of united and unseparated concaved friction surfaces, interrupted only by the vertical juncture points or edges of the concaved surfaces which serve to strengthen the cap and the friction surfaces against improper distortion, so that the flange is made up entirely of what may be considered a continuous series of concaved blocks all of the same size and each having the same concaved form, the concaved side of each being at the outer side of the skirt while the convex holding side of each is at the inner side of the skirt, so that when the cap is placed upon the tumbler each of these convex surfaces frictionally engages the wall of the tumbler and as the cap is forced thereon under pressure these friction surfaces are forced or spread lengthwise and outwardly to the necessary extent, the metal ofthe skirt being sufficiently resilient for this purpose, so that all around the tumbler the cap is held in place by a large number of flattened friction surfaces (see Fig. 7) which have proved in practice to be very efiicient. In a 63-millimeter cap for instance, it has been found desirable to provide such a size of ca with about twenty-six of these concaved riction surfaces, so that when this style of cap is forced on to the tumbler there are twentysix holding surfaces.
In the shallow form of cap shown, each of these concaved friction surfaces is of greater length than the height circumferentially of the skirt, though of course this might vary according to the depth of the flange.
This improved construction of cap enables it to be effectively used wit-h glass containers even though they do not have a uniform dimension or outer sealing surface, and can be readily forced on to the container as is usually done by machinery in a very rapid manner, and when forced on will effective- 1y hold against premature detachment and yet the user can readily remove it without either mutilation of the cap or breakage of the container.
Located within the cap is a suitable liner 8 whereby the hermetic sealing of the container is obtained.
This improved cap is particularly well adapted for use with containers that are hot packed, since the construction facilitates the escape of the air during the hermetic sealing of the cap through the medium of the liner or gasket on to the container, as the air can readily escape adjacent to the juncture points 14: (see Fig. 7 between the flattened surfaces 11, thus there is no danger of the cap blowing off during the capping of the container while at the same time the enlarged flattened surfaces 11 all around the tumbler very effectively hold the cap in place, as has been found in practice, without however interfering with the proper removal of the cap without mutilation thereof or liability of breaking the container, so that it can be readily reused by the purchaser.
It is to be understood that by describing in detail herein any particular form, structure, or arrangement, it isinot intended to limit the invention beyond the terms of the several claims or the requirements of the prior art.
Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be used, or all of the modes of its use, I claim:
1. A metal friction cap comprising a top and a depending skirt having exteriorly therearound a series of Widely spaced apart narrow vertical ribs exteriorl connected by concaved surfaces of materia 1y greater circumferential width than said ribs, the inner convex face of each of which forms a friction surface to enga e the glass container, whereby on the application of the cap each of the convex faces is flattened out to form a friction surface of substantially one-half the length of such convex face.
2. A metal friction cap comprising a top and 2. depending skirt having exteriorly therearound a series of widely spaced apart narrow vertical ribs exteriorly connected by concaved surfaces of materially greater circumferential width than said ribs, the inner convex face of each of which forms a friction surface to engage the glass container, each of said concaved surfaces being narrower vertically at its middle than at its juncture points with said ribs.
tened friction holding surface of substantially one-half the length of such curved surface when the cap is forced on to a container.
4. A metal friction cap comprising a top and a depending skirt having exteriorly therearound a series of widely spaced apart narrow vertical ribs connected by curved surfaces of materially greater circumferen-,
tial width than said ribs, each of said surfaces having greater circumferential length than height and of suflicient resiliency to form a flattened friction holding surface when the cap is forced on to acontainer.
5. A metal friction cap comprising a top and a depending skirt having a beaded, curled or rolled lower ed and a series of sharply united concaved i lock like friction surfaces extending substantially from the top to the rolled lower edge of the cap, and each of greater circumferential length than height and of suflicient resiliency to permit the fric tion holding portion thereof on the container to be increased on the applicaton of the cap to the container.
6. A metal friction cap comprising a top and a depending skirt having 'exteriorly therearound a series of widely spaced apart narrow vertical ribs exteriorly connected by concaved surfaces of materially greater circumferential Width than said ribs, each extending substantially from the top to the lower edge of the cap and of suflicient resiliency to permit the friction holding portion thereof on the ntainer to be increased to substantially onealf the length of such concave surfaces on the application of the cap to the container.
' A metal friction cap comprising a top and a depending skirt having a narrow annular band at its top and a narrow annular reinforcing band at its bottom, said bands being exteriorly connected by a series of widely spaced apart narrow vertical ribs exteriorly connected by elongated concaved surfaces of materially greater circumferential width than said ribs, the inner convex face of each of which forms a friction surface to engage the glass container, each of said surfaces having a greater circumferential length than height.
