IMPROVEMENTS IN OR RELATING TO FEEDING BOTTLES OR APPARATUS FOR ADMINISTERING ALIMENTARY FLUIDS OR SEMI-FLUIDS
Year: 1884

page_text: . I LOUIS ANTOINE VICTOR PELLEGRIN of Toulon sur Mer in the Republic of
France, but at present residing at West Hill Wandsworth in the County of Surrey,
Civil Engineer do hereby declare the nature of my Invention for "IMPROVEMENTS
IN OR RELATING TO FEEDING BOTTLES OR APPARATUS FOR ADMINISTERING
ALIMENTARY FLUIDS OR SEMI-FLUIDS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My Invention relating to feeding bottles has reference to the fittings which are
applied to and used in combination with the bottle proper, the object of the
Invention being the production of an apparatus which shall be capable of being
mounted disconnected and cleaned with greater facility than has been heretofore
attainable with apparatus of this class.
The Invention consists chiefly of a peculiar construction arrangement and
combination of parts as hereinafter described whereby the above object is effected
but it also embraces the important feature of a stopper forming itself a conduit for
the fluid or semi-fluid and having the external flexible tube and the internal glass
or rigid, pipe respectively connected with its opposite extremities in lieu of the
flexible tubing being passed through the stopper to be connected to the internal
glass or rigid pipe as in the ordinary manner.
In order that the said invention may be perfectly understood I shall now
proceed particularly to describe the same and for that purpose shall refer to the
several figures on the accompanying sheet of drawings, the same letters of reference
indicating corresponding parts in all the figures.
Fig. 1 of the accompanying drawings is a sectional elevation of the complete
apparatus, and the remaining figures are details to be hereinafter referred to.
The combination of parts constituting the entire apparatus exclusive of the
bottle proper consists of four principal sections viz :—
1, The teat or mouth piece fittings A.
2, The external tube B.

page_text: 1st. The teat or mouth piece fittings A are arranged in the following manner,
viz :-
In the usual teat or mouth piece a is inserted, the smaller end 6 of a double
tubular union piece (shewn in detail in Fig. 2) of which the two parts b and c of
conical shape but different size are joined together at their bases with a small
annular groove or recess d between them. The double tubular union piece is also
shewn in Fig. 1, with the teat so attached, the teat being represented as embracing
the smaller end b of the union piece with its extremity entering the annular groove
or recess d substantially in the manner described in the specification to former
Letters Patent granted to me dated the 20th October 1882 N° 4999.
The teat or mouth piece thus mounted is then passed through a shield (see
detail Fig. 3) perforated through its centre e and having an external flange fand
an internal annular recess g in which latter the ring of the teat or mouth piece
becomes located when the teat or mouth piece with its union piece is firmly pulled
inside (as shewn in Fig. 1) thus making the shield perfectly firm and secure so
that no infant is able to remove it.
2nd. The external tube B is composed of india rubber or other suitable flexible
material and formed with a cap h of bell or funnel shape on each end; one cap is
passed over the part c of the union piece and over the flange ƒ of the shield,
whilst the other cap passes over the conical nipplei of the stopper C to be presently
described and at its extremity enters an annular groove or recess k at the base of
the said nipple the mode of attaching the tube B to the teat and stopper as just
explained being thus similar to the method herein before described for connecting
the teat to its union piece.
3rd. The stopper C is only one piece with an internal longitudinal channel or
conduit extending throughout its length. It consists of two main portions viz :-
an exterior portion marked Y (in the detail fig. 4) and another portion marked Z
which enters the mouth of the bottle E. The exterior portion Y somewhat
resembles the shield in shape, and is surmounted at its centre with the conical
nipple with the annular recess k at its base to which reference has previously
been made. The interior portion Z or that which enters the mouth of the bottle
consists of a slightly conical part ¹ terminating in a tail piece m of a diameter
larger than the part to form a recess for a piece of india-rubber tubing n which
firmly secures the stopper in the bottle or the stopper may be secured in the bottle
by any other suitable means. The tail piece terminates in a small nipple o of
conical form with an annular groove p between the nipple and the body of the
The stopper is also pierced at
tail piece for a purpose to be presently described.
its upper part with a fine hole g¹ corresponding with a notch q2 cut along the
internal conical part of the stopper in order to allow a regular renewal of air in the
feeder, so not exhausting the infant.
4th. The internal tube D consists of a glass or rigid pipe r over the upper
extremity of which is placed one end of a piece of india rubber tubing the other
end of which is stretched over the nipple o and enters the annular groove p in a
similar manner to that in which the teat or mouth piece is attached to its union
piece the glass pipe being thus suspended in the bottle and movable.
It will thus be seen that the flexible tube B at the exterior of the bottle, and
the internal tube D (that is to say the glass or rigid pipe r which extends down
within the bottle to a short distance from the bottom thereof and is mounted at
its upper extremity with the flexible tubing 1) are attached respectively to the
upper and lower extremities of the stopper which closes the mouth of the bottle,
and the longitudinal channel 7 of the stopper itself forms a conduit for the fluid
or semi-fluid in lieu of the india rubber or flexible tubing being passed through
the hole in the stopper and directly connected to the glass pipe as heretofore.
My improved arrangement by thus making the flexible tubing independent of the
glass pipe gives facility in mounting, dismounting and cleaning. Not only may
the parts be readily taken to pieces and put together again, but the tubular

page_text: portions may be also thoroughly cleansed without the least difficulty not merely
with the brush (which method is almost impracticable with existing feeding bottles
by reason of the length and small size of the tubing) but by allowing the actual
passage of hot water right through. The use of cork (which substance becomes foul
very quickly) is also entirely dispensed with, and glass porcelain and the best
quality of india rubber or equivalent materials are alone employed, thus fulfilling
the indispensable condition of perfect cleanliness and securing in the highest degree,
the hygienic character of the feeder.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is
1. A feeding bottle or apparatus for administering alimentary fluids or semi-
fluids, in which the flexible tubing connected with the teat or mouth piece is
attached to the pipe entering the bottle, through the intervention of the bottle
stopper, which itself forms a conduit for the alimentary fluid or semi-fluid,
substantially as herein before described.
2nd The general construction arrangement and combination of parts constituting
a feeding bottle or apparatus for administering alimentary fluids or semi-fluids,
substantially as hereinbefore described with reference to the accompanying
drawings.'
