FFECE 18 Claims.

The invention relates to a closure structure for bottles and the like. particularly containers of glass conventionally used as containers for spiritual liquors or other liquids, for instance, perfumes and the like.

Distillers of liquor who bottle and market such beverages or perfume manufacturers selling highpriced perfumes under trade-marks of consider able value and whose products are identified by the public by such trade-mark or a distinctive label, are faced with the serious problem of preventing the reiilling of bottles in which their products were originally sold, by products of inferior quality or of a different brand. There has been no means previously devised for protecting either the public or the manufacturer from this practice. For instance, manufacturers are subject to the loss of valuable good-Will and a great deal of business by the illegal practice of unscrupulous persons in refilling the bottle of the manuii'acturer after the original contents thereof have been dispensed, for instance, in the case of spiritual liquors, at bars of restaurants and other establishments, one form of such practice being for the unscrupulous person to buy up empty bottles or a particular distiller and to refill them with a product of inferior grade and therefore of cheaper price and to recap and resell such bottles thus filled. Loss of a large amount of revenue from` taxes by governments, both State and Federal, is also incurred when such practice is carried out, as no stamp or band, evidencing the payment of tax is affixed to such refilled container.

One of the objects of the present invention is to prevent this practice by providing a bottle which, so long as it is filled with its original contents, indicates such fact by the appearance of a legend, for instance, the Word original upon a tamperproof type of closure provided upon the bottle. In accordance with my invention, I provide a construction of bottle closure which is tamper proof to the extent that the Word original or other similar indicating legend, appears clearly upon the closure so long as the original contents of the bottle have not been dispensed, in part or in Whole. As soon as the bottle has been opened, for instance, by the removal of the original cap therefrom, the closure member is necessarily rotated in such manner as to bring into view another legend, ior instance, the Word usedj indicating that the bottle has been opened, that it is no longer in its original condition in which it 'was shipped from the establishment of the distiner, and that at least a part of its original content of liquid has been removed from the bottle.

In accordance with my invention, I accomplish these objects by providing a container, such as a glass bottle, with a construction of the neck of` the glass bottle which has been slightly modified from the conventional glass neck of a bottle, so as to be adapted to receive a metal or other closure member and a cap which cooperate with the modified form of glass neck in such manner as to indicate, immediately upon the unscrewing of the cap, the fact that the bottle has been opened. In this manner, anyone handling the bottle so opened, is immediately apprised of that fact. My novel construction is such that it is impossible, after the bottle has been opened and the Word "used brought to appear on the closure member, to again bring it to a condition in which the Word original could appear. In other Words, my novel. construction of closure member or band provides an insurance that once the bottle has been opened such factor is permanently evident and any relling of the bottle With liquid of inferior quality or of a different origin would be brought to the attention of the purchaser or user.

In one form of my invention, my novel construction embodies the use of two sleeve members constituting elements of the novel structure of closure member with a system of slots and tongues disposed for cooperative engagement by one sleeve or the other and by an element carried by the cap of the bottle which causes movement of one of the sleeves in one direction upon the removal of the cap so as to bring into view the notation indicating that the bottle has been opened, which notation becomes visible through an aperture or Window in the outer sleeve. In another form of my invention, I make use of a single sleeve member, cooperating, in substantially like manner, with a tongue or spring member anchored directly to the glass neck of the bottle.

Various structural features embodied in my novel construction of closure will be pointed out in conjunction with the description of two embodiments of my inventive structure illustrated in the accompanying drawings.

In suoli drawings, Fig. l is a front View of the upper portion of the glass neck of the bottle with the metal cap in position thereon and showing the bottle in its condition of its original content; Fig. 2 is a bottom view of the metal cap; Fig. 3 is a front view of the bottle neck an-d closure with the cap removed therefrom indicating that the bottle has been opened by the appearance of the notation used in the window of the closure member; Fig. 4 is a vertical section through the neck of the bottle and through the various elements of the closure member; Fig.

is an outside View of the bottle closure; Fig. '7 is a plan View of the closure in the position thereof shown in Fig. 6; Fig. 8 is a horizontal section similar to Fig. 5 but showing the parts in a different position, i. e. after rotation of the inner sleeve member by the bottle cap; Fig. 9 is a horizontal section showing the position of the parts on still i further rotation; Fig. 10 is a vertical section along lines lill0 of Fig. 8; Fig. 11 is a partial section through the closure of a modied form; Fig. 12 is a section on the line llll2 of Fig. 1l; Fig. 13 illustrates the modified form of closure member after removal of the cap; Fig. 14 is a section on the line ill-ld of Fig. 13; Fig. l5 is a section on the line ill-i5 of Fig. 13; and Fig. i6 is a plan view of the closure member with the cap removed as shown in Fig. l5.

Referring more particularly to the drawings, in which similar reference characters identify similar parts in the several views, Il designates the neck of a glass bottle or container, which is provided near its upper extremity with the usual threading ill. The neck il is conveniently formed with a series of peripheral shoulders i9, il@ and 2i. In the peripheral surface of the neck, lying beta/'een the shoulders 29 and 2i, there is formed a slot 2li of a depth suiiicient to accommodate a tongue cut from the surface of a sleeve 2li of metal mounted for rotation upon the shoulder 2li of the bottle neck by flange 2li.l The sleeve Eil extends upwardly to a point above the shoulder 25, its upper portion 2l being or" somewhat smaller -diameter than the body of the sleeve.

The tongue 23 is adapted to be flexed about its pivot 'lil to cause the tongue to enter the slot 2L as hereinafter more fully explained.

Surrounding the sleeve 2d is an outer sleeve also of metal, seated upon the shoulder i9 and extending upwardly to a point beyond the shoulder 2l, and thence inwardly into contact with the inner sleeve 2d and again upwardly to the upper extremity of said inner sleeve. At one point along the bottom peripheral portion of the sleeve 2S, a tongue 3Q is cut therein which, upon rotation of the sleeve, as hereinafter described. enters a slot 3i extending along the lower peripheral edge of the inner sleeve. For accommodating such tongue 30, a slot 32 is provided in the glass neck. The sleeve 23 is provided with a peripheral window 33 through which the legend Orig or Used, printed, lithographed, or otherwise produced, upon the outer surface of the inner sleeve 2li will appear, as hereinafter described.

The upper peripheral edge ofthe outer sleeve 2Q is cut to provide a cam surface Sli having a rise 35, while the upper peripheral edge of the inner sleeve 2d is provided with a notch 36. Into this notch is adapted to enter and abut against the upstanding edge thereof, a tongue 3l cut and depressed, from the horizontal'annular surface 38 of a metal cap S9 having threads (lli c0- operating, when the cap is screwed onto the upper end of the bottle neck, with the threads I8 thereof. The engagement of such edge of the notch 35 by the tongue 3l occurs, as will be pointed out hereinafter, after the cap has been placed in position, the tongue beingfree to ride up the rise 35, and when the cap is rotated in the opposite direction (to remove the same) Engagement of the edge of notch 35 by the tongue 3l will then cause rotation of the inner sleeve 2d to bring the legend Used opposite the aperture 33 in the outer sleeve 29.

In the modified form' of my inventive structure, illustrated in Figs. 1l to 16, inclusive, the neck d of a glass bottle is provided with a peripheral slot il having a projection or post 42 extending thereinto near one end of the slot, a metal spring being anchored at one end 43 about said post, the free end d4 of the spring extending within and along the length of the slot.` In this form of my inventive structure, a single sleeve d5 is used in which, at a point conveniently substantially diametricallyr opposite the aperture t6 in the sleeve, there is provided a tongue lll' cut, and depressed, from the peripheral surface of the sleeve, which tongue, upon rotation of the sleeve, as hereinafter described is abutted by the free end of the spring The glass neck, extending above the slot 4I, between the post d2 and the free kend of the spring fill, may be provided with a notch d8 to permit the sleeve to be placed in position by the pasthrough such notch, of the inwardly extending tongue il, or such touffue, after being out, may be depressed from the peripheral surface of the sleeve after the latter has been positioned upon the glass neck.

The upper peripheral edge of the sleeve 45 of' this modified form is provided with a cam suriace i9 having a rise 5e and an abrupt edge 5l, against which latter a depressed tongue 52, cut from the horizontal annular portion 53 of the cap is adapted to abut and cause rotation of the sleeve #i5 to bring the aperture thereof opposite the legend Used, when the cap is turned for removal from the bottle neck.
