Specification of Letters Patent.
Patented Dec. 23, 1915.
Application filed February 20, 1912, Serial No. 678,895.
To all whom it may concern:
Be it known that I, RANSOM R. BAKER, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, did invent new and useful Improvements in N ursing-Bottles, of which the following is a specification.
My invention relates to nursing bottles, and it has for its primary object the production of a bottle of this kind which is more convenient to handle by a child than bottles now in use and which is absolutely sanitary owing to its construction permitting easy access to every point thereof.
Other objects are to so construct the two parts of the bottle that there will be a natural flow or gravitation of milk to the nipple without compelling the child to lift the bottle above a horizontal plane, which in bottles now in vogue is necessary and very tiresome on the child particularly when consuming the last half of the milk or liquid food preparation; to provide the bottle proper with an opening considerably larger than the cross-sectional diameter thereof so that a hand can be inserted and the bottle thoroughly washed without resorting to the use of a brush and so that thebottle may be filled without the use of a funnel; and to so arranged and position the nipple that the orifice thereof is at the lowest point when the bottle is held in a horizontal position, thus making it unnecessary for the child to raise its arm into an uncomfortably high position and tiring it.
Other objects are to construct the bottle with an angular portion at its bottom so that the child can readily grasp it beneath the longitudinal center and thus further aid in avoiding undue elevation of the childs arm while draining the bottle; to provide a construction which will more easily permit the cap to be applied to the bottle; and to otherwise improve the bottle to the end that it can be more conveniently handled by a child.
With these and other objects to appear hereinafter, the invention consists in the novel features of construction and in the arrangement of parts to be hereinafter described and more particularly pointed out in the subjoined claim.
In the drawings,-Figure l is a central longitudinal section of a complete bottle embodying the novel features of my invention;
the same being shown in a horizontal position. Fig. 2 is a perspective view of the bottle proper. Fig. 3 is a cross section taken on line ee, Fig. 1.
In the drawings in which similar numerals of reference refer to like parts in the several figures, l designates the bottle proper or body portion, and 5 the cap. The bottle 4 is made comparatively short so that a child need not reach forward so far as necessary with bottles now in vogue and to this end it is enlarged in cross-sectional area so that it will have a capacity fully equal to that of other but longer bottles; it being so formed, however, that at its lower end it is made angular, as at 15, and somewhat narrower than midlength. The upper or open end of the bottle is beveled, as at 6, so that the opening is much larger than the cross-sectional size of the bottle, thus making it possible to insert a hand thereinto when cleaning and rendering the interior angles and corners easily accessible.
The bottle is gradually restricted inwardly from its open end, as at 7, and from its point of greatest restriction and also from the lower end of the bottle it is bulged outward or enlarged, as at 8, to increase the capacity. The desired capacity is therefore obtained in a much shorter bottle than bottles now is use having the same capacity, yet the bottle is so formed at the side opposite the enlargement 8 that it can be con veniently takenhold of by a child without straining its fingers or tiring it. The angular portion of the bottle extends from the bottom to a point about midlength and from this angular region the bottle is gradually curved to the upper or open end.
By sloping the open end of the bottle the opening is made oval and along the edge of the bottle a bead 9 is formed over which is to be stretched the cap 5. This cap, which may also be termed a nipple member, is of oval or substantially oval formation and is dished to provide a rim 10 which is adapted to be stretched around the head 9 of the bottle and at its edge said rim has an en largement or bead 11 which fits against the underside of the bead 9, thus assuring an air-tight fit between the bottle and cap.
At one end of the cap, (the lower end when the bottle is in use and the higher end when standing upright) a nipple 12 is formed which has the usual orifice 13 through which the milk or other liquid food is to be drawn and at or near its opposite end (the upper end When the bottle is in use) is a vent 14.
The nipple 12 is preferably arranged at a slight angle to the bottle so that the orifice therein is in a plane beneath the milk in the bottle When the latter is held in horizontal position. By means of this arrangement it Will be found unnecessary to hold the bottle in even a horizontal position until only a small quantity of milk remains therein. By placing the nipple as described there is a natural flow of milk to the nipple and at no time Will it be necessary to elevate the bottle above a horizontal plane.
It may be said that the nipple is placed at the lowest point when the bottle is held in a horizontal position and that under like conditions the vent 14 is at a high point or in a plane above the greatest point of restriction so that air Will be admitted to the bottle to assist in the proper escape of the milk or other liquid food through the orifice in the nipple.
The inclination of the upper end of the bottle greatly aids in the ready application of the cap thereto and also in the removal of the same therefrom, and the placing of the nipple to one side of the longitudinal center of the bottle, preferably as described, is a decided advantage.
It is apparent that certain features of this invention can beused without others and that changes can be made in details of construction without departing from the spirit of the invention.
Having thus described my invention, what I claim is,
A nursing bottle having its upper end open and being gradually restricted downwardly from its upper end and provided with an intermediate enlargement at one side of its vertical center extending from said restricted portion to a point near the bottom of the bottle, the walls of said enlargement being curved and the bottle being angular in cross section opposite said enlargement, the upper open end of said bottle being inclined to provide an elongated opening, and a nipple member closing said upper open end and having a nipple in line with said angular portion.
In testimony whereof, I have aliixed my signature in the presence of two subscribing Witnesses.
RANSOM R. BAKER.
