Application May 4, 1937, Serial No. 140,661

14 Claims.

This invention relates to improvements in protective closures.

The main objects of this invention are:

First, to provide a sealing and protective closure or cover member adapted to be removably mounted on a bottle, drinking glass, or other container to cover and protect the same.

Second, to provide a protective closure or cover of the type described which is highly efiective for the purpose and capable of repeated use.

Third, to provide a protective member of cupshaped form treated with an adhesive such as rubber latex or other adhesive having the characteristic or quality of adhering to itself but not become afllxed to a dissimilar surface.

Fourth, to provide a cup-shaped member conformed and treated as stated which is well adapted for association with articles to be packaged such as candles, for example, to serve as a packing to prevent them from adhering to each other or being marred through contact, and at the same time can be removed without leaving marks on the articles packed.

Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawing in which:

Fig. 1 is a perspective view of the bottle-like container having my protective closure or cover applied thereto.

Fig-2 is an enlarged view mainly in vertical section of the structure shown in Fig. 1.

Fig. 3 is a bottom or inverted view illustrating the structural details of my closure or cover member, parts being conventionally shown.

Fig. 4 is a fragmentary enlarged horizontal section illustrating structural details.

Fig. 5 is a fragmentary view partially in section illustrating a package of candles with my protective member or cap used for packing and separating the candles.

Fig. 6 is a perspective view of the adaptation of my improvements shown in Fig. 5.

Referring to the drawing, the reference numeral l represents a bottle of substantial size such as is commonly used for the delivery of distilled water, spring water and the like. It will be understood, however, that the purpose for which the bottle or container is used is unimportant, but my closures or covers are now widely used on bottles for delivering water. The cork 3 is of conventional type.

In use such bottles as described are normally exposed during delivery and even in use, while the contents are being consumed, and are therefore usually free to accumulate dust and germs. This accumulation around the mouth of the bottle renders the same unsanitary. In order to shield the necks of the bottles, the rims of drinking glasses and various other containers, and protect the same against dirt, dust and foreign matter, I provide a seamless tapered cup-shapedclosure or cover member 4 formed of paper and having pleated side walls, the pleatings being shown at 5 (see Figs. 3 and 4), These cover or closuremembers of a single size are adapted for a wide range of articles but, of course, may be made in varying sizes.

In the embodiment illustrated the cover or closure is adapted to fit quite snugly against the upper end of the projecting cork 3 and to be compressed against the sides of the neck 2. The cover member is provided with an inner circumferential zone or strip of adhesive indicated at 6 preferably extending to the lower edge or at least terminating near the lower edge of the side walls. In the illustration it extends to the lower edge of the side walls.

The adhesive coating extends into and be-' tween the pleats. For this purpose I provide a relatively tacky adhesive having the property or characteristic of repeatedly adhering to itself but, generally stated, being non-adherent to dissimilar surfaces; that is, while it may have a sealing or retaining engagement with the surface to which it is applied, it can be readily freed therefrom without the adhesive remaining or sticking to such surface. I have found a rubber compound such as latex which may be applied in liquid form very suitable for my purpose.

Having the adhesive applied as described, the cover member may be placed over the neck of a bottle, for example, and squeezed or compressed and fitted therearound, and the pleating will permit its being readily conformed to the particular size of the article to which it is applied. Of course, there are limits to which the closure or extending member may be extended or collapsed, but a single size is adaptable for quite a wide range. When it is desired to remove the member it may be readily pulled off, it is easily replaced, and is effectively retained. It will be observed that it does effectively protect the neck and rim of the bottle, for example, which is very desirable in the delivery of water, milk and various other materials. The cover member may also be used in hospitals for covering glasses containing medicines and in numerous other remember or protecting member in packing candles as indicated at 8, Fig. 5. As shown in Fig. 6, the general shape of the protective member is cylindrical. It has the pleated wall indicated generally at 1, the pleats 8 being arranged parallel with the axis of a cylindrical body such as a candle 9. The protecting member is provided with an adhesive carrying sealing zone so that it may be snugly fitted around the candle, the adhesive acting as previously described. In packing, each candle is provided with a protecting member at one end and these being arranged in reversed relation the candles are held in separated relation and effective packings provided therefor. The candles being kept out of contact are not injured in appearance by rubbing of the surfaces thereof or by the surfaces becoming fused together under undue heat.

Other adaptations and embodiments of vmy invention will be apparent to those skilled in the art. I have illustrated and described the invention in embodiments which I have found very practical and have not attempted to disclose all the adaptations of which my invention is capable.

Having thus described my invention what I.

claim as new and desire to secure by Letters Patent is:
