SCREW-CLOSURE FOB. BOTTLES AND OTHER RECEIETACLES.

Specification of Letters Patent.

Patented Oct. 18, 19m.

Original application filed February 6, 1907, Serial No. 355,986. Divided and this application filed October Serial No. 397,006.

To all whom it may concern:

Be it known that I, ARTHUR WILZIN, a citizen of the United States, and a resident of Paris, France, have invented certain new and useful Improvements in Screw-Closures for Bottles and other Receptacles, of which I tures of the bottle or other receptacle whereby the same cooperates with the cap.

The present application is a division of another "application filed by me in the United States Patent Oifice on February 6, 1907, Serial No. 355,986, which has ma use into United States Patent 937,401 dated October 19, 1909 in said earlier application I have claimed an im roved method of screw-capping bottles an other receptacles.

In the accom anying drawings, Figures 1 and 2 are vertical sections illustratin one form of my cap and the manner of app ying' it to a receptacle. Figs B and 4 are respectivelya vertical section and an elevation showing another form of my screw cap. Figs. 5, 6 and 7 are respectively an elevation, a vertical section on line AA of Fig. 5 and a partial horizontal and greatly enlarged sectionon line BB of Fig. 5, illustrating a third form of my invention; Fig; 8 is an elevation ofthe bottle neck used in connection with the cap shown in Fi s. 5, 6 and 7. Fig. 9 shows the same bott e neck with thefcap shown ready for unscrewing. Figs. 10, 11' and 12 illustrate still another form of my invention, Fig. 10 being an elevation of the bottle neck with the cap applied, Fig. 11 a vertical section of the two, and Fig. .12 an elevation of the bottle neck alone Figs. 13,514 and l5 represent a further construction, Fi 13 showing bottle andcap in elevation, ig. 14L in vertical section and Fig. 15 being an elevation of the bottle neck alone. Figs. 16 and 17 are an elevation and a plan view respectively of a form of screw cap provided with longitudinal (vertical) ribs or folds, and Fig. 18 shows this cap applied to a bottle.

perfectly after filling the bottle, the y The neck of the bottle, jar or other receptacle a, that is the part adapted to receive the annular portion or flange of the cap, is provided with a screw thread I). Adjacent to the threads of this neck I slide or slip axially a cape the flange of which in the form of my invention shown in Fig. 1 is plain or smooth so that it need not be turned relatively to the bottle to bring the cap home, with the packing disk Z (of cork or other suitable material) engaging the mouth of the receptacle. Pressure is exerted longitudinally or axially by any well-known or approved mechanism to hold the cap firmly against the bottles mouth and insure a tight joint. Then, while the, ca is so held, it is forcibly-pressed im ward y any suitable mechanism, so as to cause the flange of the cap to mold itself perfectly. against the screw thread I). An example of a mechanism suitable for this purpose has been indicated in Figs. 1 and 2 and consists of 'aws or rolls 6 provided with elastic v(rub er) facings j which become deformed under pressure as shown in Fi 2 thus making the cap conform closely ea in the same manner wil complete the shaping or molding of as above described the screw thread on the cap to fit'exactly the threaded portion 6 of the receptacle.

I prefer to lock the'cap against rotation relatively to the bottle before or while exerting the inward pressure to mold the flange of the cap to the screw threads of the bottle. This locking may be accorn plished in various manners. For instance, as shown in Figs. 3'and 4 and also in Fig. 18, the bottle or other receptacle a may be provided with a notch it below the screwthreadedortion b to receive a tongue 9 projected rom the lower edge of the cap. 01', as shown in Figs. 5 to 9 the bottle neck a may have a screw thread k notched or inthe tongue obviously need not project down- Wardly beyond the fla-nge of the cap, but I prefer to do this to enable the tongue to be more readily grasped and bent upward when it is desired to release the cap so that it may be turned to open the receptacle. To faciliate this manipulation of the tongue, I may provide a weakened horizontal line m at the upper attached end of the tongue and also, if desired, weakened vertical lines j at the sides of the tongue, so that the latter may be broken off enti'ely, as shown in Fig. 9. It will be observed, however, that in any event the upper portion of the cap flange, adjacent to the bottom or disk of the cap, is continuous so as to give it the strength and elasticity required to hold the cap in tight engagement with the receptacle along all points of the circumference. This remark also applies to the construction of the locking means illustrated by Figs. 10 to 15. Here the locking element or surface provided on the bottle a below the screw thread 6 consists, not of a notch, but as an equivalent, of a projection k adapted to be engaged by a concave, portion or recess on the .tongues g or g respectively. In these two constructions, instead of the merely weakened lines 7' of Figs. 5 and 7 I have provided slits or incisions 7' so that the sides of the tongue are perfectly free, its upper end being attached to the cap flange along the weakened line m.

The preferred form of my cap, illustrated in Figs. 16, 17 and 18, is rovided in its entire height with longitudinal (vertical) ribs or folds c whichhave a twofold purpose first, they render the cap flange expansible and contractile within certain limits so that it may fit the receptacle prop erly notwithstanding variations or inaccuracies in the diameter and form of the neck. Second, these ribs or folds, which in the finished closure extend across the screw threads of the cap, and project therefrom outwardly (Fig. 18) afford a better hold for the fingers of the person in unscrewing or otherwise handling the cap. The tongue 9 which in this located between two of the ribs 0 and projects entirely below the cap flan e to enter a suitable notch may be provi ed with a weakened line m at its upper edge to facilitate breaking off.

It will be understood that vertical ribs or folds such as 0 may be a plied to other forms of screw caps as weli.

One great advanta e of the screw cap a plied as above described is that it fits t e screw thread of the receptacle with absolute accuracy, even when sald thread is irregular as it unavoidably is when molded. An ordinary screwcap necessarily has its thread form of my invention is widened when screwed down over a somewhat irregular thread on the bottle, and therefore does not fit perfectly tight. My cap, however, is not screwed on or turned when it is first applied to the receptacle, and no widening of the thread can occur, but a perfect fit is obtained. A further advantage of my invention is the rapidity of the closing operation, much less time being required to slip the cap into position and then mold it against the threaded neck than to screw a cap home. Still another advantage is the possibility of using machiner for screwcapping receptacles; with ordlnary screw-caps this could not be done efficiently, for the reason that it would be impossible to determine whether or not the cap was screwed on far enough and there would be danger of stripping the thread on the cap or breaking the receptacle if the cap were screwed too far. The longitudinal (vertical) ribs are of advantage in enabling the cap to expand or contract and thus fit necksof different diameters and shapes within certain limits; moreover, as above explained, these ribs afford the user a better hold in unscrewing the cap and screwing it on again. The locking tongue prevents the cap from turning relatively to the bottle during the process of molding the cap flange against the threaded neck, as also during transportation, so that the cap cannot be jarred loose. At the same time, the presence of an uninjured tongue indicates to the consumer that the rece tacle and contents. are still in their original condition, for in tuming the tongue away from the neck to release the cap, the, tongue is either broken off completely (Fig. 9), or at least.so altered in ap pearance as to show plainly that it has been tam ered with. Of course, after the cap has een unscrewed, it can be screwed on by hand like an ordinary screw cap for closing the receptacle temporarily, as in this case the joint need not be so tight as when the bottle is closed for the first time.

I claim as my invention:

' 1. The combination of a receptacle having a screw thread and a locking surface at a different level, with a 'cap provided-with a threaded flange in engagement with said screw thread, said flan e having longitudinal ribs on its entire helght extending across its threads, and a tongue rejecting from the edge of said flange and in locking engagement with said locking surface to keep the ca from turnin relatively to the receptac e, the attache end of the tongue being connected with the flange along a weakened line.

2. The combination of areceptacle having a screw thread and a locking surface at a different level, with a cap provided with a threaded flange in engagement. with said screw thread, a tongue projecting from thu edge of said flange and in locking enga ement with said locking surface to keep t e cap from turnin relatively to the receptacle, and longitu inal ribs concaved toward the axis of the receptacle and extending across all thethreads of the cap.

3. The combination of a receptacle having a screw thread and a locking surfaceat a different level, with a cap provided with a threaded flange in engagement with said screw thread and a tongue (projecting from the edge of said flange an in locking engagement with said locking surface to keep the cap from turning relatively to the receptacle, the'attached end of the tongue being connected with the flange along a weakened line.

4. A closure cap provided with a threaded I flange which has longitudinal ribs extending across its threads, and also a tongue adapted for locking engagement with the receptacle, the attached end of said tongue bein izonnected with the flange along a weakene 5. A bottle cap provided with a flange the upper part of which, at least, is circumferentially continuous, said flange having a screw thread 0 ening out at the bottom thereof, inwar ly concaved longitudinal ribs intersecting all the screw threads and extending the whole height of the flange, and a locking element attached to said flange and adapted to be readily detached therefrom. y

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses, this 8th day of October, 1907.
