Description

Jan. 7, 1936. A. GROSS 2,026,890
SCREW CAP OR COVER WITH BRUSH Filed Jan. 23, 1953 Imventor Patented Jan. 7, 1936 UNITED STATES PATENT OFFICE Application January 23, 1933, Serial No. 653,213 In Germany November 11, 1932 1 Claim.
Several types of screw-caps or covers combined with a brush are known. They are mostly used with containers, the contents of which, such as medicaments, cleaning or varnishing lotions,
5 or adhesives, are applied by means of a brush. The manner of fastening the brush into the cap or cover has up till now had certain defects, which have been remedied-in the present invention.
A cover is for instance known, provided with a washer of cork or similar material, a brush handle consisting of a length of metal wire being fastened to the washer. The brush could easily fall out when in use. It has therefore already been sug-. gested to fasten the brush to a boss connected with the inside of the cover. In such cases, hollow material was generally made use of for handles (e. g. the well-known quills). As however the internal space varies very greatly with quills, a reliable fastening of the latter with the boss was not possible. The quills have also been replaced by thin metal tubes, into the lower portion-of which the bristles were squeezed the upper part being pressed over the boss. On account of liquid contents which have power to dissolve, the
cementing medium used for fastening the brush handle to the boss was not permanent. By tapering both the boss and the handle, in an attempt to fasten the brush so securely, that the handle would not loosen after a longer period of use and in spite of the dissolving power of the liquid, it was found that this tapering failed in its purpose.
One method of carrying out the invention is illustrated in the drawing, in which:
Fig. 1 is a vertical sectional view through the improved device showing the parts connected together,
Fig. 2 is a side elevational view of the cap, and
Fig. 3 is a side elevational view of the brush.
Referring now, more particularly, to the accompanying drawing in which similar reference numerals are employed throughout the several views there is provided a screw-cap or cover a,
preferably made of some kind of moulded material (artificial amber, artificial horn etc.). b
is the boss for the handle, which it is advisable to. make in one solid piece with the cap. The boss is provided with an external screw-thread. In 5 the interior of the screw-cap there is a washer g of rubber or cork. As will be noted the washer g is apertured so as to snugly fit about the boss when inserted in the cap. The brush handle consists of a thin brass or aluminum tube, at the 10 lower end of which the bristles d are fastened.
A counter-thread is provided at the inner end of the handle. This inner end is also provided with the flared edge 1.
Before the handle is screwed upon the boss b', 15 the latter is coated with some special cement f. The handle is then screwed on so firmly that the flare f is in tight contact with the washer 9.
Apart from the fact that the screw-thread connection affords a special hold to the brush, the 0 flared edge at the top of the handle, guarantees that no contents within the container, apt to dissolve the cement, can enter the interior of the brush handle.
A device of the character described, comprising a flanged cap-like body, a boss integral with and depending centrally from the inner surface of the flanged body and having an external screwthread, a brush, a handle for carrying the brush including a, hollow metal tube having the inner end internally threaded for engagement with the boss, an apertured annular sealing member inserted within the flanged body and about the boss, the inner end of the tube being flared outwardly so that when the tube is screwed tight the flared end will firmly engage the sealing member and a cementitious material acting to bind the handle to the boss to prevent accidental relative movement between the handle and the boss and also prevent admission of the liquid contents of the container to the cementitious material.
