inventa Witness@ j EDWARD E. ETTER, oFv'rRTLEfcREEK, PENNsYINlfNIag.
To aZZ'f-whom 'it mlvyfcohcemf l [Be it known that I, EDWARD E; E'ITER,
. citizen vof the United States, residing at Turtle Creek, in the county of Allegheny and 4 State of Pennsylvania, have invented certam new and useful Improvements in Nursing-Bottles, of which the following is a o specification.
This invention comprehends certain 'new and useful improvements in nursing bottles of that type that are designed to admit air into the bottle as the contents are withdrawn therefrom, and' one of the objects of the invention is a sim le and efficient construction of nursing bottllell of this character, whiclris composed of comparatively few parts that may be cheaply manufactured and readily assembled. And a further object of the invention is a nursing bottle of this type', the air inlet means of which are embodied in a cap adapted to be secured to the open-base body portion of the bottle, so that the cap,
may be easily detached Whenevernecessary for the purpose of cleansing the bottle, which manifestly may thus be more easily effected than when the neck portion thereof must alone be depended upon forthis purpose.
With these and other objects in view that will more fully appear as the description proceeds, the invention consists in certain constructions and arrangements of the parts that I shall hereinafter fully vdescribe and claim. A
Fora full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction, reference is to be had tothe following description and accompanying drawing, in
which Figure 1 is a longitudinal sectional view of a bottle constructedv in accordance With my invention,"a portion thereof being shown in side elevation; Fig. 2 is a detail top plan view of the bottle cap detached; Fig. 3 is a detail perspective view of the valve employed; and, Fig. 4 is a sectional view of the base portion of the bottle, illustrating the valve in the raised or open position which it will assume in the operation of withdrawing the contents of the bottle throughthe nipple end thereof. l
Corresponding and like parts are referred to in the followin description and indicated in all the views o the drawing, by the same reference characters.
Specification ofLetters Application led June 26,
isos. seal No. acaso,
. -.Referring to the drawing, thenumeral 1 designates the body portion of a nursing bottle which may be of any desired construction and design', -2 the neck thereof and 3 the nipple which mayl also be of any .desired material, construction or design, as I'do not deadnuttmg air into the bottle as the contents are sucked therefrom. In the present instance, the body ortion 1 of the bottle is constructed entire open at the bottom and is designed to be cfosed b means of a cap of metal or any other desire material, said cap being detachably secured to the base ortion of the body'l by means of the threaded engagement of the sides 5 of the cap with exterior screw threads formed on the body portion near the lower end thereof. The cap 4 is formed with a preferably centrally disposed raised portion 6, and around the margin of said raised portion with a circular series of apertures 7.
The valve in the bottle, in the present instance, comprises a disk-like membrane 8 of rubber or 'similar substance, and it is formed with a preferably centrally located slit 9 formed, for instance, byan incision in the material of which the valve is constructed. The valve 8 is formed with a thickened rim 10 which may be interposed between the lower edge of the body portion and the cap 4, as clearly illustrated 1n Figs. 1 and 4, so as to securely hold the valve in lace, and at the same time subserve the a ditional function of a seal at this oint.
In the practica use of a nursing bottle constructed as set forth in the foregoing ,description and illustrated in the accompanying drawing, it is evident that the contents of the'bottle are prevented from iiowing out through the ports or apertures 7 by the engagenent of the major central portion of the valve 8 with the raised portion 6 of the ca 4. When the contents of the -bottle are suc ed out through the nipple 3, it is clear that the valve 8 wlll rise from the elevated portion 6 of the cap, and air will be drawn in through the apertures 7 and the slit or incisioni) in the valve, thereby avoiding any collapsing of the nipple, and insuring that the infant shall properly obtain milk orl other liquid within the bottle, thus overcoming animportant cause of colic. It will also be seen that by my invention, the cap 4 may be easily detached from the body portion of the pend upon the nipple to provide means forA Patented may' 1 1, 190e.
whenever necessary to adjust the parts and that when detached, the .bottle may be thoroughly cleansed.. y
Having thus described the invention, what I claim is: l
1. A nursing bottle, the body portion of which is formed with an opening a cap secured to the body portion and c osing said opening, said cap being formed with a raised ortion, and air inlet apertures, and a valve bottle` termed with an opening therein above said raised portion an adapted to normally rest upon said raised portion of the cap, as and for the purpose set forth.
l2. vA nursing bottle, the body portion of which is formed with an open bottom, a cap secured to said body portion and closing said bottom, said cap being formed with a raised portion and a series of apertures around said raised portion, and a valve membrane se- 2o cured between said body yortior'a. and said cap and formed with a slit, t e litted portion of the valve being adapted to rest upon the raised portion of the cap.
In testimony whereo I aix my signature 2.5 in presence of two witnesses.
