2 Claims.

This invention relates .to a functionally an structurally improved closure. 7 i

It is an object ofthe invention to provide an article of this character capable of use in numerous associations, but primarily intended for they purpose of sealing vessels suchras for example, bottles, and by means ofwhich the contents thereof will be effectively prevented from w escaping by evaporation or otherwise.

Another, object of the invention is that of providing a closure which may be unseated with minimum effort and which closure will, despite severe stress, have its component parts remain a in properly assembled condition.

Another object of. theinv'ention is that of providing a closure which may have associated with it a swab and the construction of which closure will besuch that the swab will remain as a unit thereof throughout the entire life of the article.

An additional object is that of providing a closure, the construction of which will be relatively simple so that the device may be manufactured to the greatest extent by automaticmachinery. Moreover, this device will embody rugged characteristics so that maximum life will be incorporated within the same.

With these and other objects in mind, reference is had to the attached set of drawings il- 0 lustrating practical embodiments of the inven- Figs. 6 and 7 illustrate additional structures which may be included within the teachings of the present invention.

While a closure constructed in accordance with the present invention may be manufactured of many different materials, it is preferred that it be formed of a moldable material such as bakelite, or other phenol product. Such materials lend themselves especially to the construction of closures which should be moisture and air-proof and are to be capable of withstanding rough usage.

Thus, referring primarily to Fig. 1, the numeral l0 indicates a closure formed of a disklike body having a downwardly extending flange ll adjacent its outer edge and the exterior face of which, as in Fig. 4:, maybe serrated to provide a roughened surface [2 by 5 means of which the cap may be readily gripped and manipulated. The area of this cap should, in the embodiment under consideration, be adequate to insure that the pouring lip ofthe loottle is enclosed withinthe flange. ,The latter is concentrically disposed with respect to a sec ond flange l3 whichdefines thespace within which the plugor stopper M is to be disposed; This second flange has a radius such that it N lies within the neck ofthe bottle and it will consequently be appreciated that the entire lip of the receptacle is thus effectively protected. With a view to securing the stopper to the cap it is preferred, according to the present invention, that a series of spaced annular grooves I5 be formed in the inner cap face to provide trough portions within which cement or similar material may be keyed for the purpose of preventing a dislodgment of the stopper or plug I l. Obviously, the latter may be formed of any desired material as, for example, cork and with the construction aforenoted it will be observed that not alone is the pouring neck of the bottle protected adequately, but also that it is possible to secure a major purchase on the outside of the flange in order forcibly to dislodge the cap and plug from association with the bottle, and the plug or stopper will remain coupled to the cap even under most strenuous conditions of use. 0

With a View to assisting the withdrawal and insertion of the plug or stopper, it is preferred that the latter as in Fig. 1 be formed with a bore 16 which will break the vacuum or pressure except under final stages of sealing or initial stages of withdrawal. The same results may be achieved by, for example, forming a groove H in the side Wall of the plug or stopper.

Closures of this nature are quite often employed in connection with a receptacle, the contents of which require the use of a swab. Considerable difficulty has been experienced in securing such an element against accidental displacement. In order to overcome this objection,

it is proposed, when necessary, to apply an element of this nature to the closure that the cap of the latter be extended as at I8 in Fig. 2 and and passed to extend through the fibrous body W of the former as has been indicated in Figs. 2 and 3.

The teachings of the present invention and more especially the coupling of the rod to the cap are not limited to the construction shown in Figs. 1 and 2. For example, the cap 2|, as

shown in Fig. 5, may have a bored extension 26 for the purpose of accommodating the ro d ifi.

Where this construction is resorted to, it is ob-' vious that a relatively deep groove is provided for the reception of a cement or similar material to retain the plug applied to the cap. As indicated in dotted lines, a complementary extension 21 might extend from the upper surface of the cap in order to assist in manipulating the same. Also, if desired, the rod as at 28 in Fig. 7 might be molded integrally out of the cap, material. However, due to the liability of breakage it is usuallypreferred that the rod be a unit or element separate from the cap.

As at 29 in Fig. 6, a cap of the general type shown in Fig. might, of course, be constructed without employing a rod structure in association therewith. This cap might, moreover, be provided with an extension 21 as previously described.

Where, however, a rod I9 is employed, it is preferred as shown in Figs. 2 and 5 that the rod be formed with a relatively extended portion or portions as at 30 and around which at the time of forming the cap, the moldable material is caused to extend. Thus, while in certain instances, it might be feasible to rely solely upon frictional contact of the parts, there is provided by the construction just describedor its functional equivalent, an anchoring provision which will prevent completely any danger of accidental displacement.

With structures such as the foregoing, it will be appreciated that among others the objects asspecifically aforenoted are achieved. Obviously, numerous changes in construction and rearrangements of the parts might be resorted to without departing from the spirit of the inven- "tion as defined by the claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A closure including a cap, a plug secured to the inner face of said cap, a bored extension forming a part of said cap and a swab mounting rod extending through said plug and having frictional engagement with said bore, the outer end of said rod being split and extending angularly with respect to the rod body.

2. A closure including, in combination, a cap, an extension projecting from the inner face of said cap and integraltherewith, said extension being formed with a bore, a swab-mounting" rod extending into said bore, an enlargement form'- ing a part of said rod and within said bore to lock the same against displacement, and a plug formed with an'opening for the accommodation of said rod and secured to the inner face of said cap, said rod lying in contact with the face of said plug opening. 7
