Application filed ril 16, 1917. serial ltd 162,273.

To all whom it may concern:

-Be it known that I, WILLIAM J. DAVIS, a citizen of the United States, and a'resident of Chicago, in the county of Cook and State of Illinois, have invnted certain new and useful Improvements in Milk-Bottles and Caps, of which the following is a full, clear, and exact specification. I

My invention is concerned with improvements in milk bottles and caps therefor, and

is designed primarily to produce a bottle of. the class described with a cheap and practical cap, so designed and constructed that when the cap is removed, the contents of the bottle can be readily poured out without permitting them to come in contact with any portion. of the bottle that has not been protected by the cap.

My invention is further concernedwith a bottle of the class described, provided with a cap so constructed that the air which would tend to be compressed -in the hollow of the can is released until the cap comes in contact with the mouth ofthe bottle and the sealing is completed. I

My invention is further concerned with a bottle having a novel bottom which is de signed to be more easily washed by machinery than are the bottles heretofore used.

To illustrate my invention, I annex hereto a sheet of drawings in which. the same reference characters are used .to designate identical parts in all the figures, of, which- Figure 1 is a central vertical section through the bottle showing the cap in place;

Fig. 2 is a side elevation of the preferred form of the cap with a portion thereof broken away and in central section, to show the sealing cut;

F 3 is a top plan View of the cap;

Fig. 4 is. a central vertical section of a thickness of the edge 9 is secured by foldmg modified form of the cap;

Fig. 5 is a and v Fig. 6 is a view of the month without the cap.

The eneral shape of the body of the bottle a embm iying my invention is that of the customary milk bottle, although it will be understood that the invention is not necessarily confined to bottles of. this general shape. The bottom I), however, is differently designed in that the corners are rounded oif by a considerable curve, and the center of the bottom is occupied by the protuberance.

c, which it will-be noted is connected by a top plan View of the same;

Specification of Letters Patent. I Patented Sept 17, I

continuously 'concaved surface with the rounded corners, so that when a jet of water is directed into'the center of the bottle, as occurs in some forms of bottle-'washing-machines, the jet of water will strike on the point of the-protuberance c and be deflected along the concaved surfaces, thus washingout the bottom and the corners much more effectively than is possible where the center of the bottom of the bottle is flat, as in that case, the water striking the bottle tends to rebound and does not necessarily flow into the' corners. This, of course, is especially true where the bottles have the water thrown into them their inverted position, as is sufli'cient distance to make the deep andv narrow annular channel f, which annular channel is adapted to receive the annular edge 9 of the cup-shaped cap h, which is of the proper size'and thickness shown, so that when the cap is forced down over the mouth of the bottle, as shown in Fig. 1, the edge 9 thereof will enter the recess f, and I hold the cap securely in place against any accidental removal. These caps are prlncipally constructed if some vegetable fiber, such as pasteboard, straw-board, etc., and in the pre-' ferred form shown in Figs. 2 and 3, the annular walls of the cap are formed by cor rugating and pressing them into shape from the flat disk from which the cap is formed.

In the modification shown in Fig. 4:, the

back an annular portion 9' of the cap, the two folds inthis case being thick enough to fill the channel.

100. With the corrugated 1 form shown in Figs. 2 and 3, the natural j tendency of the folded ortion to expand helps to keep the cap in place. V Where .the interior of the cap is substantially cylindrical, necessitating a cylindrical exterior of the flange d, it becomes neces-' sary to make some provision for the escape of the air that tends to be confined-between the cap and the top of the contents of the bottle, as soon as the edge of the cap is started in its downward movement over the flange d, and for this purpose I preferably provide the semicircular cuts in at the proper point in the top 'of the cap, and when these cuts are made, the tongue Z resulting therefrom is forced down into the interior of the cap enough so that there is a free passage for the air to escape as the 'cap is shoved down into place. These caps are preferably coated with paraflin, and it will be obvious that as the cap .is rammed home,.as it appears in Fig. 1, the outer .end of the tongue 1 will engage the upper edge of the flange d and be forced up into its closed position, the parafiin acting as the sealing agent sufliciently to make the closure air-tight when the ca is in place. I

Wit these caps having the cylindrical outline, it is possible to place them one above the other, without their nesting, in the sup ply tube of a bottle capping machine, whence they can be fed by a pushing stroke over the top of the bottle in the same manner as are the ordinary caps now in use.

To. facilitate the removal of the caps from the bottle, and alsoto make sure that they cannot expand at the bottom sufliciently so as to overlap the top of the cap below in the supply pipe of a bottle capping machine, I may form the folded annular flange m, seen in Fig. 4, and it will be understood that with the. thinner material shown in this form it is easier to form the flanges m.

. While'I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purpose, it W111 be understood that it is capable of some modifications, and that I donot desire to be limited in the interpretation of I the following claims, except as may be necessitated by the-state of the prior art.

What I claim as new, and desire to secure 7 by Letters Patent of the United States is:

1. In a bottle and cap, the combination with a bottle having an elongated, generally cylindrical exteriorv sealingsurface just be-- as to be engaged and closed thereby when it is brought in contact therewitln 1 2. In a bottle and cap, the combination side portion,

drical fibrous cap having its disk-like top adapted to rest on the top, of the pouring flange and its annular bottom flange adapted to enter and be forced in it to close tightly by itself the entire annular recessformed between the two flanges to hold the cap from expanding and secure it in place simply by a downward movement, and to be removed by a simple upward movement without destroying either the bottle or the cap.

3. The combination with a glazed bottle adapted for repeated use having a narrow high annular flange at its mouth over which. its. contents are poured without-coming in contact with the second flange, and a second annular cap-securing flange outside of the first and at a substantially lower level, the

two flanges between them forming a narrow vertically disposed channel, the lower por-' tion of which is the same width throughout but narrower than the thickness of either flange and into which the edge of a cover inclosing the inner flange may be forcedby a direct downward movement along-the axis- I of the bottle, the top of the pourlng flange extending above the top of the cap-securlng flange a distance greater than thethickness of either flange, of a slightly flexible fiber cap having a circular center and an annular the rim of which enters the annul'ar channel and place and the bottle sealed without deforming either it or the bottle by engaging when seated both the outer wall of the inner flange and the inner wall of the outer flange, substantially as and for the purpose descrrbed.

In witness whereof, I have hereunto set holds the cap securely 1n my hand and aflixed my seal, this ninth day of April, A. 1);.1917.
