:
We FELIX RUTARD and FRANCOIS DELAS trading as Rutard & Cie of Amboise
(Indre et Loire) in the republic of France Glass Manufacturers do hereby declare
the nature of the said invention for "IMPROVEMENTS IN FEEDING BOTTLES" and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention relates to improvements in feeding bottles, the object of the
invention being to provide better means than are at present in use for stoppering
or closing the mouths of feeding bottles.
In carrying out our invention we construct the stopper or cap of the feeding
bottle of metal and glass or of glass alone or of other suitable natorial, the said
stopper or cap being constructed to fit over or into the mouth of the feeding bottle
and being provided with the usual hole to receive the india rubber tube and also
with a valve or openings for the admission of air.
In order to enable our invention to be fully understood we will describe the
same by reference to the accompanying drawing in which figures 1, 2, 3 and 4
ropresent sections of feeding bottles constructed according to our invention. In
figures 1 and 3 the bottles are shewn with straight necks and in figures 2 and 4
with bent necks.
In figures 1 and 2 the stopper consists of a cap or collar a, of metal, hard india
rubber or other suitable material. This cap may be formed by moulding or
otherwise with a screw thread to screw onto a male screw thread b, on the neck of
the bottle as shown in figure 1, or it may be provided with projections c, c, adapted
to take into inclined bayonet slots d, d, on the neck of the bottle as shewn in
figure 2. These projections c, c, and bayonet slots d, d, are clearly shewn in the
detached views at figures 5 and 6, figure 5 being a horizontal section of the cap
and figure 6 being a side elevation of part of the neck of the bottle. In the upper
part of the metal cap a, we fix the flanged disc f, of glass or other suitable material
and having the usual hole for receiving the usual rubber tube g, and the air hole h,
with a nipple i, over which is sprung the short india rubber tube forming the usual
valve for the admission of air.
To make a tight joint between the stopper and the neck of the bottle we place a
ing or washer k, of suitable elastic material such as cork or india rubber around
ho disc, and under the flange f¹, thereof as shewn so that when the stopper is

page_text: screwed or turned on the neck of the bottle the elastic ring or washer k, will be
pressed between the flange f', of the disc f, and the top of the neck of the bottle.
The india rubber tube g, is provided with the usual seat l, at its outer end and with
the usual glass tube m, within the bottle. The valve j, may if desired be arranged
at the top of the stopper instead of at the bottom thereof.
Instead of forming the stopper of two parts as shewn in figures 1 and 2 we
sometimes form the stopper of a cap n, of glass, porcelain or other suitable
material as shewn in figure 3, in which case we place a washer of suitable elastic
material around a groove on the outside of the neck of the bottle; the elastic
washer A, in this case serves to fix the stopper on the neck of the bottle, no screw
thread or bayonet fastening being required; k, is the ring or washer to form the
joint between the stopper and the bottle. In this arrangement we dispense with
the air valve h, j, and in place thereof form two holes or grooves o, o, at the side of
the hole through which passes the india rubber tube g; the holes or grooves o, o,
are clearly shewn in figure 7, which represents a plan of the cap or stopper.
In the modification shewn in figure 4, we dispense with the cap herein before
described and provide the stopper B, with an elastic washer k, which fits in a
groove formed around the stopper; the washer k, in this case tightly fits the
interior of the neck of the bottle and serves both to fix the stopper in the bottle
and also to make the joint.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1
The manufacture and use of the improved feeding bottles hereinbefore described
and represented in the accompanying drawing.
