1 Claim. (01. zit-10c) prevent the contents of the bottle from spilling out of the bottle while the user is drinking there-' from.

A further object of this invention is the production of a simple and eflicient sanitary drinking cap for bottles and thelike, which cap is so constructed as to properly vent the bottle to which the cap is attached, thereby facilitating the even flow of liquid from the bottle' and through the cap. I

Other objects and advantages of the present invention will appear throughout the following specification and claim.

' In the drawing:

Figure 1 is a perspective view of the sanitary drinking cap shown upon the neck of a bottle, a

portion of the cap being shown in section;

Figure 2 isa vertical sectional view through the cap and a portion of the neck of a bottle, showing the cap in the process of being attached to the bottle; and

Figure 3 is a longitudinalsectional view of the neck of a bottle and cap, the cap and bottle being shown in a drinking position.

II designates the bottle neck which is provided with the conventional cap-retaining bead II. In carrying out my invention, the conventional By referring to the drawing, it will be seen that crimped cap is removed and my improved sanimy drinking cap i2 is attached to the bottle.

This cap I! is preferably formed of resilient waxed card-board, or other material, which may be obtained at a minimum cost. Light metal or other similar material, may be used without departing from the spirit of the invention, and the sanitary drinking cap may be easily stamped or pressed from sheet material and manufactured by automatic machinery.

The sanitary drinking cap I! is provided with a resilient crimped depending flange ii, the edge I of which is inturned slightly to flex under the bead ii when the cap I! is attached to the bottle tohold the cap in place and to flexoutwardly while the flange I3 is being forced over the bead 1 ll,-as shown in'Figure 2." The cap i2 is provided with an outer wall it which overhangs the mouth of the bottle when the cap is in position upon the ing cap having an outer flat wall, a resilient flange user may be used as a valve by moving the lip toas new is:

bottle. The outer wall it is provided with a central aperture it. p I

An inset drinking spout ll which is open at its outer end extends outwardly of the wall I! and partly surrounds the aperture I6, as shown. The spout i1 is provided with a ut-away portion or vent opening II on one side, which extends the full length of the spout ll. Thiscut-away portion it extends from the outer end of the spout ii to the point where the spout ioins'the wall it. The side edges of the cut-away portion I! are gradually curved from a point approximately the longitudinal center of the spout l'l outwardly in the direction of the edge of the cap and merge into the outer wall it, as shown. All edges are smooth to avoid injury to the mouth of the user. The aperture it extends laterally of the cut-out portion l8, as shown in Figures 2 and 3. I

The formation of the cut-away portion It, as described above, will place the inner end of the cut-away portion It to one side of the longitudinal center of the spout and above the lip of the user when the spout I1 is in a drinking position, as shown in .Figure S. The approximate position of the lips will be seen by noting the dotted lines in Figure 3. The upper lip of the ward or away from the wall I! to control the venting of the cap and bottle. when the upper lip A shown in dotted lines in Figure 3 is moved away from the wall II, the vent opening formed by the cut-away portion 18 will be enlarged and the liquid within the bottle will flow more freely, but when the lip A is moved toward the wall II the flow of liquid is retarded. Furthermore, the cap 12 fits tightly upon the beadli thereby preventing liquid from leaking between the cap and bottle. The upper lip of the user may be manipulated to prevent overflow of liquid out through th cut-away portion or vent. opening ll.

From the foregoing description, it will ,be seen that a simple and emcient sanitary drinking cap has been provided which maybe readily applied or attached to the conventional soft-drink or similar bottle, to facilitate drinking from the mouth of a bottle. Through the use of this cap, the flow of liquid may be easily controlled by the user, and theuse of a drinking straw may be eliminated, thereby avoiding danger of spilling the contents upon the clothing of the user. 'Having described the invention, what I claim As an article-of manufacture, a sanitary drinkcarrled by the outer edge of said wall and adapted to engage the head of the neck of a. bottle for seating the cap upon the neck of a bottle, the flange having an inturned edge for flexing under the heald of a bottle neck, said wall having a central apertur inset from the outer edge of the cap to provide a. wide flat lip-abutment portion entirely surrounding the aperture, an open sided spout partly surrounding said aperture and protruding outwardly of the flat wall adjacent the 2,soo,ssu

edge oi the aperture, the open sided spout defln-
