To all whom t may concern.'
Be it known that I, FRANK J. Ciascuna citizen of the United States, residing at Cuyahoga Falls, in the county of Summit and' State of Ohio, have invented ycertain new and useful Improvements in Nursing Bottles, of which the following is a specification, reference being had therein tothe accompanying drawing. y
This invention relates to certain new and useful improvements in nursingl bottles,.the object being to provide a botti which` is so constructed that air Will be admitted into the bottle, as the milk is drawn out through the nipple so as to prevent a'vacuum from being formed, thereby overcoming the difliculties existing with the nursingb'ottles now in use. v
Another and further object of the invention is to provide a bottle with avent closed by a flexible member which is so constructed that it snugly fits the neck of the kbottle so as to prevent the milk from passing' out through the vent yet allows air to passin through the vent into the bottle as the milk is withdrawn.
Other and further objects and advantages of the invention will be hereinafter setV forth and the novel features thereof deined by the appended claims.
In the drawing I have shown aY side ele vation of a nursing bottle, partly in section, illustrating one embodiment of my invention and while I have shown a specially shaped bottle, it is, of course, understood that I do not wish to limit myself to any particular shape of bottle or the number of vents used.
In carrying out; my invention I employ a bottle, preferably vformed of glass, comprisfrom the shoulder of the bottle to the mouth of theneck and is provided with an interior annular groove for the purpose hereinafter fully described. 1
The neck of the bottle is provided with an air vent 3, the outer wall of the neck being enlarged around the vent as clearly shown, but it is, ofcourse, understood that this is not essential and the outer wall of the neck might be provided with an annular rib through which the Vvent or vents could extend.
- Arranged within the neck of the bottle 'is a rubber sleeve 4 provided with an enlarged bottle.
ing a body l having a neck 2 which tapersupper edge forming ,anIV annular bead adapted lto be seated in the annular groove formed in theneck of the. `bottleliat the mouth. f The sleeve slightly tapers from the bead orl uppery edgetowards the lower edge thereof and isada'pted-lto vfit snugly'withm the neck of the bottle.
The sleeve is inserted from the top and as the neck gradually tapers, it fits snugly the interior of the neck at thek junction of the body so that the contents of the bottle is prevented sleeve. l
The tube collapses so as to allow air to en-y ter the vent and An ordinary nipple 6 can Abe used and as the milk is drawn out of the bottle through j i i the nipple, the sleeve yields in order to allow air to pass vthrough the vent Vinto the passinto the interior of the from passing out around the body ofv the bottle which prevents the nip;
yple from collapsing, thereby overcomingthe y y, driculties now existing'wlth nursing. bottles.
F rom the foregoingdescription it will be lseen that I have provided a y'nursing bottle'- with a neckhaving a vent. in the kwall thereof l over which-isarranged a rubber sleeve hav-y ing an annularv bead at its upper` edge to reinforce the same to facilitate the insertion f of the sleeve within the neck, whereby a bottle is constructed which allows air to enterl the same as the contents -is drawn out.
'Ihev sleeve can be readily removed and the bottle sterilized in the ordinary manner, the sleeve` being alsosterilized so that -a thoroughly sanitary bottle .is formed and as the Vvent hole is protected by the sleeve,.it
is never exposed to the contents of the bottle.
As the contents ofthe bottle is withdrawn through the nipple, a partial vacuum is cre# f ated within the bottle and the rubber sleeve collapses slightly` so as to allow airto come in through the Avent hole. i
What I claim. is: v LA nursing bottle providedwith a neck havinga. vent in the wall thereof and a flexi- Y ble sleeve arranged within the neck of the bottle over said vent and fornring a valveV for said vent.
2. A nursing bottle having a taperingV neck. provided with' a vent and a flexible rubber sleeve arranged withinV said neck over said 'vent and forming alvalve forl said vent.
3. A nursing bottle having a vent and a rubber sleeve arranged over said vent to 'form a valve for said vent and so constructed that the contents of, the bottle passes th-rough'said sleeve and the valve. opens to allow air to enter said bottle through said vent When a partial vacuum is created therein. l
4;. As a new artiole of manufacture, a ni'irsing bottle having aftapering -neck .pro-
vided "With a vent inthe Wall thereof, a ruloloer sleeve Iarranged Within the neck of saidbottle extending from the mouth of `the neck to a point beyond the vent rand forming a, valve forfsaid vent.
A nursing bottle having a neok provided With a vent infthe Wall. thereof and m-ysi-gnature. f
