MILK BOTTLE CAP Sept. 6, 1938.
Eiled March 5, L937 ATTORNEY.
Patented Sept. 6, 1938 UNITED STATES PATENT OFFICE 3 Claims.
This invention pertains to closure caps and more especially to such as are designed for the closing of milk bottles. Among the objects of this invention are the provision of a cap which can be manufactured and sold for a less price than the most popular caps now on the market; to provide a. cap of the character indicated which will aiford a greater degree of sanitation than the previously manufactured caps; to provide a cap which will furnish a perfect seal for a standard milk bottle; to provide a cap which will reduce to a minimum the space on the top of the cap wherein water and dirt can collect; and such further objects, advantages, and capabilities as will hereafter appear and as are inherent in the construction disclosed herein.
In the drawing annexed hereto and forming a part hereof,
Fig. 1 represents a plan view of a cap embodyso ing the present invention;
Fig. 2 represents a fragmentary section substantially along the plane indicated by the line 2-2, Fig. 1;
Fig. 3 represents a fragmentary sectional view of a part of a cap to which the printed label has not yet been attached. Reference will now be made in greater detail to the annexed drawing for a more complete description of this invention. In the drawing, a 30 bottle is represented by the letter B, while the cap is represented, in generahby the letter C. Inside of the pouring lip, a standard milk bottle is provided with a ledge i for the reception of a closure'cap of any suitable type. One of the popular capsof the present day is constructed somewhat along the lines indicated in Figs. 1, 2, and 3 of Patent No. 1,615,157. However, a. cap with a deep top opening, such as shown in this patent, furnishes too much room for the collection of water and dirt on the'top thereof. The cap which I have produced comprises a circular grooved portion 2 adapted to fit closely the pouring rim of the milk bottle. The outer periphery of this cap is provided with a rib or bead which furnishes a reinforcement for the cap, thus rendering it more diflicult for the rim ofthe cap to expand when moist and being handled.
The inner portion of the grooved rim is extended inwardly in the form of a flat ring 4 which rests upon the ledge I of the milk bottle to close the mouth thereof. The central portion of the cap is dome shaped, as indicated at 5, which permits easier application of the cap to a bottle, the upright wall 6 of the cap being slightly larger in diameter than the corresponding wall of the bottle so that it is necessary for this to contract somewhat when the cap is being placed upon the bottle. This furnishes an outward pressure upon the mouth of the bottle to hold the cap in place after it has been inserted.
As shown in Fig. 3, the cap is formed with a tapered rib l at the top of the grooved portion,
and this furnishes an opening for the reception of the label disc 8. It is'usual in this art to make up the body of the caps without the discs 8 and store them for use later when an order is received for a supply of caps. When the order is received, the required printing is placed upon the discs 8, and these are then inserted into the opening within the flange i and the edge of this flange is forced inwardly, as indicated at 9. This furnishes means for retaining the label in place. The rib 1 also furnishes a fulcrum about which the channeled rim of the cap may operate when a pull is exerted on the rib or bead 3 tending to remove the cap from the bottle. The effect of such a pull is to tend to draw the part 6 outwardly into tighter engagement with the mouth of the bottle.
It will of course be understood that the specific description of structure set forth above may be departed from without departing from the spirit of this invention as set forth herein and in theappended claims.
Having now described my invention, I claim:
1. A bottle cap comprising a central section to rest upon the bottle ledge and close the mouth of the bottle, a channeled rim integral with said central section to surround the pouring lip of the bottle, part of the substance of said rim rising from the crest thereof and being adapted to be bent over to secure a disc in place thereon, and a disc resting upon the top of said rim and extending only to the crest thereof, said disc being secured in place on the rim by bending over said part of the substance.
2. A bottle cap comprising a central section to rest upon the bottle ledge and close the mouth of the bottle, a channeled rim, continuous with said central section, to surround the pouring lip of the bottle, a disc resting upon the top of said rim and extending to the crest thereof, and a flange extending upwardly from said rim and turned inwardly over the edge of said disc to hold same attached to said rim. v
3. A bottle cap comprising a central section to rest upon the bottle ledge and close the mouth of the bottle, a rim continuous with said central section rising to the top of the bottle mouth and extending outwardly and downwardly around the edge of the bottle, a flange extending upwardly from the crest of the bottle edge-enclosing portion, said flange being concentric with the central section and being upwardly tapered, and a disc fitting closely within said flange and having the,
edge of the flange turned over to hold the disc in place and furnish a substantially flat top for the FRED B. COLE.
