.15 Claims.

The present invention relates to .a valved nursing bottle. In particular, it relates'to a-nursing bottle having an air port in the lower end thereof, and a valve for controlling the air port so that the same may be opened or closed at will.

It is an object of the invention to provide a nursing bottle of this kind that has a valve means that is entirely sanitary. A further object is to provide a nursing bottle of this kind having a valve means that may be operated by a very simple actuation, so that it may be opened or closed quickly at any time. A particular object is to provide a valve means of this kind that may be opened or closed by the thumb of the hand that is holding the bottle, so that the use of the bottle and the valve will be one-handed.

A further object of the invention is to provide a valve of this kind having completely:detachable parts, so that they all may be cleaned. In this connection, anespecial object is to provide a valve means having its operating parts completely removable from the bottle, and associated holding means on the bottle that is open and accessible for cleaning.

Other objects will appear in thedescription to follow.

In the drawings:

Fig. 1 is an elevation of a nursing bottle, showing the valve in place;

Fig. 2 is a view of the bottom of the bottle in its preferred form, with the removable valve parts withdrawn;

Fig. 3 is a side elevation of the removable valve actuating means in its preferred form;

Fig. 4 is a transverse section through the valve and bott e, taken on the line i 3 of Fig. 1;

Fig. 5 is a view similar to Fig. l but showing the valve open;

Fig. 6 a sectionon theline 6--% of Fig. 4-;

Fig. '7 is a view of a preferred .form .ofthe valve washer;

Fig. 8 is a sectional view of a modified form.

of valve actuating means;

Fig. 9 is a section on the line 9--9 of Fig. .8;

the understanding of the full description that the valve may be inserted into an extension formed by enlarging the outside dimensions of the bottom of the bottle, without changing the internal opening thereof, or by merely providing a boss on one side of the internal wall of the bottle near its bottom, and that other like arrangements may be used.

The bottom of the bottle is thereby provided with a relatively thick section [4 on at least one side. This section is provided with an undercut recess 15 that extends transversely to the bottle. and terminates in a wall 16 that is preferably slightly beyond the middle of the bottle, when viewed as in Figs. 1 and 2. It is most desirable tomake the wall i6 generally perpendicular to the bottom of the recess 15, as appears clearly in Fig. 4, although it will be understood that these shapes may be varied within the limits of the operating mechanism.

The bottle at the inner part of the recess I5 isprovided with an air port ll that extends from the interior of the lower well [3 of the bottle through 'to the recess l5.

This port ll is valved by a removable mechanism. This includes, first, a resilient washer l8 that may be made of rubber or the like, and which preferably is square or suitably corresponded to the shape of the recess, so that when it is inserted it will engage with the walls of the recess and be held against accidental removal or displacement. Preferably, also, it is rounded off 1 on its outer edge so that the valve operating mechanism may be inserted over it easily. It has through it a port 253 that. when the shaped washer is inserted into the inner end of the recess and against the wall ltgwill be in registry with-the port ll of the bottle.

Secondly, a valve actuating means (Fig. 3)

which includes an insert portion 23 that is shaped on its sides and bottom to correspond with the shape of the sides and bottom of the recess l5. In other words, in preferred form, it is tapered so as to slide into the recess from the shallow end thereof and to be held there against outward removal by the undercut shaping of the walls of the recess l5. This valve actuating means is cut away on its inner surface to receive the washer, and to engage the side thereof opposite the wall l 6 so as to hold it in place. EXtending across this cut-away space and mounted in the insert, in a manner such as is shown in Figs. 3 and 4, there is a spring-like closing blade 25 which acts as a 'valving member. This is actuated by an over-center bell crank type of handle that'may be 'pivotally held in a cut-away portion 21 in the outer surface of the valve actuating means, and projecting slightly therefrom. It will be seen that the operation of the handle of this member 26 to the position of Fig. 4 causes the spring-like blade 25 to compress the Washer 18 over the port [1, and to close the opening 20 in the washer, and to cause the washer to seal tightly against the bottom of the recess around the port l1. However, when the handle 26 is flipped up, as shown in Fig. 5, the ports 20 and I! are opened for ingress of air into the bottom.

A modified type of valve actuating means is shown in Figs. 8 and 9. This type may be made of sheet metal, or like material, and consists of a generally U-shaped actuating bracket 30 that has walls 3| that extend outwardly from a base portion 32 and converge, so as to cooperate with the undercut walls of the recess I5. There is an integral blade 33 that projects across the member 38 and over a cut-away portion 34 thereof. An actuating handle 35 is pivoted at 36 between the wall members 3|, and it has a cam portion 31. The operation of this type actuating member is the same as that in the original type described.

Fig. 10 shows another modification, in which the recess 55 may be the same as before, as are the washer and ports. The valve insert may be formed of a metal stamping similar to that of Fig. 8, but with the side walls cut away. The base 4| of this stamping has the end in engagement with the washer and a spring blade 42 is turned back to overlie the port 20 and normally spring outward therefrom. In this modification, the operating handle 43 is separately pivoted to the sides of the recess 15. The sides of the recess 15 have opposite grooves 45, of which one is shown in Fig. 10. The pivot ends of the handle 43 are slid into the outer ends of these grooves 45, and back to the more or less radial inner ends thereof, in which they are retained by the spring 42 acting outwardly on the crank part of the handle lever 43. By this means, the handle may be inserted and removed individually.

Operation The bottle is initially sterilized, and the valve parts may be removed at this time and sterilized separately. When they are removed, it will be seen that they consist of the valve actuating means, or its counterparts in Figs. 8 and 10, and the washer IS. The bottle is designed so that it can be cleaned readily, as is evident, because the valve receiving recess I is open and large enough so that complete cleaning of its and of the port i7 is easily accomplished.

When the bottle is so sterilized, the washer I8 is slipped into place, which may be done readily as the recess is large enough to receive sterilized mechanical holding means, and the washer will be properly located by virtue of its shape. Then the actuating means is slid into the recess 15 from the left end in Figs. 1 and 2. Preferably, in this position, it engages the free edge of the washer and holds it in place. This also disposes the blade 25 over the port 20 when the handle is in the position of Figs. 3 and 5. The actuating means has sufiicient spring or friction to prevent accidental removal from the recess IS. The handle may be flipped down, to the position shown in Fig. 4, compressing the blade over the port 20 and closing the opening. Then the bottle may be filled with the formula.

When the bottle is used for feeding an infant,

the person feeding the infant will hold the bottle with its lower end above the nipple end. As the infant Withdraws milk from the bottle, there is a low pressure condition developed in the bottle that retards the outflow of milk. This may cause excessive labor on the part of the infant, and consequent failure of the child to get enough food. This characteristic is peculiar to mechanical feeding means, and thus imposes upon the bottle-fed infant a labor that is not required of a breast-fed infant.

With the present invention, the person feeding the child can hold the bottle in the hand in proper position for the infant to withdraw the milk therefrom. The person, while so holding the bottle, may with the thumb flip the handle 26 upwardly to open the valve, and thereby admit air through the ports 20 and I! of the washer and bottle, respectively, so as to vary the low pressure that resists the withdrawal of the milk by the infant.

Furthermore, if, because of some sudden necessity, the person is required to withdraw the bottle from the infant and set it down, the valve may be closed with no delay whatever by merely flipping the handle 26 back into closed position by the thumb of the hand holding the bottle. The bottle may then be set up on its bottom without leaking. It may be seen that a very sanitary and very simply and quickly operatable valve means has been provided. Modifications in it are evidently possible within the scope of the disclosed invention. The mechanism of Fig. 8, which preferably is made of metal, has certain advantages of simplicity of construction, although the operation is the same.
