W. GLASS BOTTLE CAP Filed Sept. 14, 1927 r m m Patented Dec. v 1 1, 1928.

UNITED STATES PATENT OFFICE.

WIL IAM amiss, or CAMPBELL, 01110.

r BOTTLE car.

Application filed se tember 14,1927 Serial No. 219,461.

. ented rubber caps of one Saul Schulhoif,

identified'by No. 1,093,211,'under date of April 14, 1914. I

It follows that the present invention is an'improvement'upon this patented cap as well as other known rubber caps on the market.

The structural features and advantages of the improved cap as well as this advantage of known caps, will be made clear from the following description and drawing.

In the drawings:

Figure 1 .is a fragmentary perspective view of a milk bottle neck provided with the improved rubber cap;

Fig 2 is a central vertical section thru the same. Fig. 3 is a view like Fig. 2, showing the relationship of the cap to the bottle under predetermined conditions.

Fig. 4 is a horizontal section through the upper portion of'Fig'. 3.

Referring now to thedrawings-by numeral s, it will be seen that the reference character 5 designates the neck of an ordinary milk bottle which, as is usual, is provided at its upper end with an outstanding annular bead 6 whose outer face is of customary convex formation. At the juncture of the bead and neckisthe customary seat 7- upon which the usual paper cap is placed.

The improved rubber cap, which cooperates with these parts, is generally designated by thereference character 8. This cap is characterized by a rim portion-9, the inherent resiliency of which causes it to conform to the surfaces of the bead 6 with v which it is adapted to cooperate. This terminates at its bottom in a ring-like band 10 while at its top it merges into a' comparatively rigid rib 11 adapted to rest upon the ledge or seat 7. h

Formed integral with the rib and spanning the space over the discharge end of the bottle neck is a comparatively flexible disk-like diaphragm or cap portion 12.

Particular attention is invited to a circular groove formed in the internal sur face of the rim portion 9 and functioning as a channel. Communicating with this channel and extending diagonally and 'downward, are circumferentially spaced openings or discharge ports 14.

- Under normal conditions, the cap is fitted upon the bottle as represented in Figs. '1 and 2, wherein. the rim portion 9 snugly contacts the bead 6, while the ring-like band 10 surroundsthe neck just below the bead. Also, the rib 11 bears firmly down upon'thc seat 7. Thus, an air-tight and liquid-tight closure is provided.

Under certain conditions, and particularly in coldweather, the contents of the bottle freezes and expands, and in the pres-- ent arrangement, the construction, permits unhampered expansion. As shown for instance, in Fig. 3, the portions 9, 11 and 12, 7

are forced out of contact and into spaced relation with the cooperating portion of the bottle, thus compensating for expansion small leakage, and preventing breakage of the bottle.

In the foregoing description and draw- .ings, it will be seen that I have evolved an exceptionally simple and inexpensive cap for milk bottles which is characterized by such indispensible features as simplicity in construction, ease of manufacture, large quantity output, and efiiciency in use.

The head of the bottle is protected from damage, and germs are prevented from depositing thereon. Hence, the structure makes for sanitation. In addition, the cap provides a hand grip such as will not accidentally slip off the bottle and the bottle is carried by gripping the cap. This expansion and contraction, without causing displacement of the cap, guards against the entrance of extraneous matter, and prevents the contents from oozing out.

. In fact, the improved cap appears to possess all of the advantages of known caps and 1 stoppers, and thus avoids certain outstand- I ing disadvantages which are apparent insuch caps and stoppers. Particularly do I Wish to emphasize the presence of the annular channels and the discharge openings 105 which communicate therewith and which cooperate in allowing the discharge of pressure. particularly when the contents of the bottle expands in cold weather.

' Another advantage to be noted is that the o top, being made of rubber, permits the entire article to be submerged in boiling water for sterilizing, with little liability ofthe cap accidentally coming ofl. This is not permitted with aluminum caps and the ordinary cardboard caps. In addition, the boiling action which produces an expansion in the bottle contents, is taken care of by the relief-valve action of the cap as shown in Fig. 3, which allows escape of pressure which is built up under the boiling action.

Since the foregoing advantages and features of the invention have been made plain, a more lengthy description is believed unnecsary.

Minor changes in shape, size, and rearrangement coming withinthe field of invention claimed may be resorted to if desired.

Having thus described my invention,what I claim as new is Q As a new product of manufacture, a bottle cap comprising a body composed of rubber including a concavo-convex diaphragm merging at its marginal portion into an annular rib,"and formed beyond said rib With a surrounding rim portion of general channel-shaped cross section, said rim portion" terminatmg in a ring-like band, and sand rim portion being provided between its upper and lower ends and on its internal surface with an endless channel and circumferentially spaced openings communicating therewith and extending thru the exterior surface, said openings being inclined outwardly and downwardly.

In testimony whereof I aflix my signature.
