The ultimate consumer or any distributor or dealer, by accepting only a package having the seal or indicator thereof intact, can be certain that he is obtaining the original contents of the package as shown by the trade-mark or label or other marking thereon.

In the accompanying drawing there are shown two different embodiments of the invention, but it will be understood that the drawing is intended for illustrative purposes only and is not to be construed as limiting or defining the scope of the invention, the claims forming a part of this specication being relied upon for that purpose.

Of the drawing:

Fig. 2 is a. top lview of the inner or primary closure.

Fig. 3'is a bottom view of the indicator member or outer closure,

Fig. 4 is a view similar to Fig. 3,- but showing the indicator member or outer closure relatively turned so as to break the skirt portion thereof.

Fig. 5 is a view similar to Fig. 1, but showing an alternative embodiment of the invention.

- Fig. 6 is a detail perspective view oi the ratchet device shown in Fig. 5.

Fig. 7 is a top view of the inner or primary elo.- sure shown in Fig. 5.

Referring to the drawing, particularly Figs. 1 to 4, l represents a container with which the container closure means embodying the invention may be used, the said container having a mouth or opening 2.Y The container is shown as being a glass bottle, but'it will be .understood that the invention may be used with a wide variety of containers. For instance, the container I, instead of being a glass bottle, may be a metal receptacle such as a can or barrel having projecting metallic parts for engaging the closure means. i

The indicator member or element is represented at 3 andit is shown as being a complete closure of the cap type entirely covering vthe opening 2 in the container, but I do not necessarily limit myself to an indicator member which is a complete closure. The indicator'member 3 has as a definite indication to the ultimate consumer and to each intermediate distributor or dealer who handles the package that the original contents are intact and that thre has been no substitution or adulteration. Closure means emtect various commodities, whether liquid or otherwise, such as beverages, medicines, cosmetics, food products, lubricating oils, etc.v

A container closure means of the type to which the present invention relates, includes a readily breakable indicator member which may be formed to also constitute a closure for the receptacle, ordinarily being an outer closure cooperating with a primary or inner closure. The readily breakable indicator member is preformed and is adapted to be put in place on the container without substantial change in size or shape, and it is to be distinguished from various devices of the prior art consisting of sheet metal, of paper, of fabric, or other material adapted to be crimped or folded or shrunk or otherwise put into place by a change in size or shape.' The readily breakable indicator member is freely movable into its from its normal position. Container closure means of this type are disclosed in Patent No. 1,938,063 to James P. Burke, in applicationl Serial No. 723,864 in the name of Benjamin F. Connames of Benjamin F. Conner and William F. Schmalz.

In accordance with the present invention the indicator member or outer closure is held in place by a thread engaging a thread carried by the container, and a concealed ratchet means is provided to automatically prevent unscrewing. Associated .with the indicator member is a. stop for limiting axial movement of the said member o rpclosure whenturned in the opposite or engaging direction. The aforesaid thread of the indicator member or outer closureis formed on a thin readily a breakable skirt portion thereof, and the result is that, if the rotative movement of the member or closure is continued after the stop has been engaged, the thread-n. the said member or closure definite warning to anyone handling the package a thin readily breakable skirt portion l formed with an internal thread 5 adapted to engage an external thread 8 on the container. The skirt portion 4*" of the indicator member is preferably thinner than the remainder of the side wall thereof, there being a distinct zone or line of differentiation at 1.

Associated with the indicator member 3 is a concealed ratchet means permitting the said member to be freely turned inone direction into its normal position, but automatically preventing turning in the unscrewing direction. This ratchet means may be widely varied as to details, but I prefer and have shown ratchet teeth 8 formed integrally with the top wall 9 of the member 3, these teeth being adapted to cooperate with a normally non-rotative means carried by the container. Y

Preferably-and as shown there is provided in addition to the indicator member or outer closure 3 a primary closure 4III which directly engages the container I to close the mouth thereof. 'l'he closure Il may be of any one of a variety of types, but it is shown` as being of the cap typel and as having an internal thread Il adapted to engage anexternal thread I 2 on the container adjacent the opening 2. The primary closure is provided with a'gasket or liner I3 which engages the top of the container or bottle to seal it in the usual manner. The closure I Il is covered or at least partly covered by the indicator member or outer closure 3, the relationship being such that the primary closure I I cannot be removed while the indicator member or outer closure remains in place and unbroken.

When a primary closure such as I8 is provided it preferably serves as the means for supporting that portion of the ratchet means vwhich cooperates with the before-mentioned teeth 8. As shown the closure 'Il is provided at the top with an annular series of ratchetteeth I4 adapted to directly engage the ratchet teeth 8 on' the outer closure member. Inasmuch as the ratchet teeth 3 and I4 directly engage each other, it is necessary to provide a certain amoimt of resiliency, and as shown this is obtained by making the top wall 3 of the outer closin'e 3 relatively thin. The teeth 3 are-shallow and witlr'the top wall 8 thin and resilient, the lteeth 8 are permitted to snap over the teeth Il when the outer closure screwed into its normal position as shown in Flg. 1. The engagement of the teeth 8 with the teeth Il prevents any movement in the unscrewingdlrection..

A stop is provided for limiting the axial movement of the indicator member or outer closurewhen turned in the engaging direction. and when there is a primary closure such as III, the top surface Il'ot the primary closure may serve as a stop, this surface beingongaged by a surface Ii on the outer Y A In using the closure means shown in Figs. 1 to4gthe containerisiilledinanyusualor preferred manner and the Aprimary closure I8 is put in place in accordance with-usual practice. Then the indicator member or outer closure 3 is put in'place, the thread 5 thereof being engaged with the thread 8 on the container. The outer closure is turned until the surface I8 thereof engages the stop I I, and care is taken to avoid any excessive force which would turn the said outer closure after the said stop has been engaged. It will be apparent that the teeth 8 will snap over the llas already described, and that the Said teeth will vengage each other to prevent any unscrewing of the outer closure member.

When it is desired to openthe containenthe indicator member or outer closure 3 is forcibly turned in the direction to tighten it. During such turning the teeth- 8 snap over the teeth I4 as already described. Inasmuch as the surface I6 of the outer closure is already engaged with the stop I5 further downward axial movement is impossible and the thread 5 on the skirt 4 is forced over the thread 6 on the container, thus breaking the skirt into several pieces as indicated in Fig. 4. With the skirt l broken the remainder of the outer closure 3 can be removed to permit access to the primary closure I which canv then 1- manner indicated in Fig. 4, it may be preferable to make the threads and 6 of the buttress type, these threads having their substantiallyperpendicular surfaces facing upward, as clearly shown in the drawing. 'Ihis enables the inclined surface of the thread 5 to more readily be cammed outward by the inclined surface of the thread 6 so as to facilitate breaking. l

Preferably the thread I2 on the container and the corresponding thread II on the primary closure are right hand threads so that the primary closure can be put in place and removed in the ordinary manner. 'I'he thread 8 on the container and the corresponding thread 5 on the outer `closure member are preferably left hand threads. The making of the threads 5 and 6 left hand has the advantage, that the additional turning of the closure member to eiect the breaking of the skirt thereof is effected in the left hand direction, which is the direction in which a personA would ordinarily turn a cap to unscrew it. It is not necessary for the person opening the package to have any special knowledge of the interior construction, and it is merely necessary for him to turn the outer closure in the same direction in which he would naturally turn a right hand threaded cap to unscrew it. The left hand turning of the outer closure, instead oi' unscrewing it, tends to tighten it, and this attempted tightening causes the breaking of the skirt portion thereof in the manner already described.

By reason of the ratchet means, that is the teeth 8 and I4, any'turning of the outer closure 3 in the unscrewing direction is positively pre-v not readily turn, but if the primary closure should Y The indicator member 3 may be formed of one of a variety of materials, but it is preferred to mold the said member from a material of the synthetic resin class.` Such a material is some-A what brittle and isv readily breakable when provided with a sufciently thin portion such as the Vskirt portion 4 below the line 1; and such material has the further advantages that it is available in a variety of colors and can be molded to provide any external trade-mark or ornamental design. Synthetic resin material has the further advantage that upon breaking it does not form sharp fragments or splinters dangerous to the person opening the container. The primary closure Ill may also be molded from a synthetic resin material.

It will be observed that one of the advantages of the container closure means shown in Figs. 1 to 4, is that there are only two pieces, -both of them molded. There is no separate metallic breaking or ratchet device, whichwouid add to the cost of original manufacture and which would also add to the cost of assembling the closure means with the container.

The construction shown in Figs. 5 to 7 diiers essentially from that shown in Figs. 1 to 4 in that a separate metallic ratchet device is provided between the two closures. The separate ratchet device is not ordinarily preferred,A but -it may be necessary when it is desired to \\make the .outer closure of a material not sufciehtly resilient to permit the direct engagement with the primary closure as shown in Fig. 1.

The outer closure 3 is similar to the outer closure 3 except that the top wall 9 thereof may the walls of the recess I1 and theresilient pawls I9, I9 thereof engage the teeth 8*l to prevent turning of the outer closure 38L Iin the unscrewing direction. Except for the necessity of putting in vplace the separate ratchet device I8, the manner of use of the container closure means shown in- Figs. 5 to 7 is substantially the same as that of the container closure means shown in Figs. 1 to 4, and repetition of the description is unnecessary.
