FERDINAND HERB, OF SUPERIOR,

com-em:

Be it known that I, FERDINAND HERB, a citizen of theUnited States, residing. at Superior, in the county of Douglas and State of Wisconsin, have invented a new and useful Nursing-Bottle, of which the following is a specification.

This invention relates to nursing bottles and is more particularly designed as an improvement upon the structure described and claimed in Patent #803590 issued to me on November 7, 1905.

In order to permit air to enter the bottle I otherwise than through the openingin the collapsmg,

nipple, and thus prevent the nipple from it has heretofore been necessary to form a longitudinal incision within the end of the bottle neck. This incision however is hard to clean properly and moreover -creased in thickness and weakens the bottle.

The object of the present invention is to provide a bottle which dispenses with such an lncision without however interfering with the admission of air into the nipple.

A further object is to provide such a means which does not weaken the bottle, but, on the contrary, tends to reinforce'it.

With these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention has been shown. In said drawings ;Figure 1 is a perspective view of a portion of a nursing bottle having the present improvement thereon. Fig. 2 is a longitudinal section through the upper portion of the bottle and showing, by dotted lines, a nipple in engagement there"- with. Fig. 3 is an end view of the neck of the bottle. Fig. 4 is a View of a construction slightly different from that shown in the other figures.

Referring to-the figures by characters of reference, 1 designates a bottle neck having an annular extension or flange 2 designed to be engaged by the large end of an ordinary rubber nipple such as has been indicated by dotted lines at 3. As shown in Figs. 1 and 3 a portion of. the wall of the neck 1 may, if desired, be gradually interminate in a projection or shoulder 4 which extends longitudinally of the upper portion of the neck and upon the outer side and the free end of WISCONSIN.

the flange or enlargement2. A substantially L shaped groove or recess is thus formed between the shoulder and the adjoining. faces of the enlargement 2, this recess gradually diminishing thereof.

By providing a shoulder such as described it will. be. apparent that when the large end of a rubber nipple is placed-on the neck the rib or shoulder 4 will hold a portion of the inner surface of the nipple :out of contact with the neck, thus forming an air' vent or passage through which air is free to pass into the nipple. Inasmuch as the groove or recess is produced by extending a shoulder radially. from the neck of the bottle it will be obvious that the same can be very readily cleaned by means of a brush or'the like and in no wise weakens the construction of the bottle but, on the contrary, reinforces that portion of the bottle on which the shoulder is located.

If preferred, and as shown in Fig. 4, the projection may be in the form of a well defined rib' 5 forming a substantially L or V-shaped groove or recess at each side so that when a nipple is fitted on the bottle an air passage will be provided-at both sides of the rib. These grooves or recesses gradually diminish in depth toward their lower ends. r

It will be understood, of course, that by shifting the nipple so as to extend below the rib or shoulder, air will not enter the nipple by way of the recesses formed along the rib or shoulder. However, by shifting the nipplealong the rib or shoulder so as to expose the lower extremity of said rib or shoulder a minute quantity of air will be tle. By further adjusting the nipple toward the ends of the bottle neck the quantity of air admitted in this manner can be increased.

By providing a device such as herein described the nipple is prevented from collapsing and the force necessary to withdraw the food therefrom can be controlled to suit the child. Moreover, by extending the outstanding portion partly across the end' of the bottle neck, the nipple is prevented from collapsing against the end of the bottle neck to such anextent asto prevent the passage of air from the vent to the interior of the nipple and bottle neck. k

It is of course to be understood that ribs in depth toward the lower end permitted to thus enter the nipple and botand shoulders .of different forms and proportions may be used and that various changes may be made in the construction and the arrangement of the parts Without departing from the spirit or sacrificing thevariable height and merging at one end,

' into anoutst-andin portion upon the end of the bottle neck, sai last mentioned outstanding portion extending inwardly to the mouth of the bottle.

2. A nursing bottle having a portion of its neck of gradually increasing thickness and terminating in a radially extending shoulder of variable height.

3. A nursing bottle having a portion of its neck gradually increasin in thickness to form a radially disposed s oulder extending longitudinally of the neck and partly across the end thereof, said shoulder being of variable height.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence -of two witnesses.-

, FERDINAND HERB.
