FR2662077A1 - VALVE WITH VALVE FOR BREASTFEEDING BOTTLES. - Google Patents

Abstract

The piercing comprises a central slot (2-2'), there being formed at least at one end of the slot a blind cavity (3) which has a substantially cylindrical profile and whose base, formed at a very slight depth, is cut radially so as to delimit deformable flaps, thereby permitting a functioning in the manner of a valve capable of permitting the intake of air into the feeding bottle while at the same time counteracting the inadvertent passage thereof during the manipulations carried out when the teat is outside the baby's mouth.

Description

The present invention relates to nipples intended to be adapted

  on the opening of nursing bottles.

  We know that in their classic form, teats, made of natural or synthetic rubber, have, opposite their open part arranged to be fixed on the neck of the bottle, a hole formed by one or more holes suitable for allowing flow of porridge into the child's mouth It should be noted, however, that

  obviously this drilling also allows the liquid to leak out

  laughing at the bottle when the latter is handled while the pacifier is not

  is not yet or is no longer in the infant's mouth.

  It will also be observed that the entry of air inside the bottle, entry which obviously accompanies the exit of the liquid out of it, frequently disturbs the operation, to the point that it arrives

  often the teat goes into depression when it is intro-

  picks up in the child's mouth, the air cannot penetrate

inside the bottle.

  It is to all of these drawbacks that the pre-

  invention, which has as its object a pacifier which, all being suspected

  tible to be made of any material, natural or synthetic

  that, and especially silicone, is capable of giving complete satisfaction to the mother or nurse by avoiding any unexpected expulsion of liquid and by controlling the movements of opposite directions of the

porridge and air.

  The teat according to the invention is essentially remarkable in that its piercing comprises a slot at at least one of the ends of

  which is arranged an opening arranged to operate at the ma-

  niere of a clean valve to allow the entry of air into the bottle

  while opposing any untimely passage of liquid during handling.

pulations of it.

  The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing: FIG. 1 is a vertical section showing, on a very enlarged scale, the arrangement of the piercing of a nipple established in accordance with

the invention.

  Fig 2 is the plan view of the end face of the teat

  which is facing the inside of the bottle.

  Fig 3 is a detail section, made transversely by

  relative to the central slot of the hole.

  Fig 4 is a section along the plane indicated in IV-IV in

fig 1.

  Fig 5 is a section along the plane indicated in V-V in Fig 1.

  Fig 6 reproduces fig 3 when the bottle is oriented with the teat facing down.

  In this drawing, the reference 1 designates the wall which forms the end

  mite (sometimes referred to as a "nipple") from the nipple and which

  includes the hole intended to allow the passage of liquid porridge

  quide, which bore is, in the usual way, placed inside an area delimited by two projections la with an arcuate profile,

  opposite to each other at the outer face of the wall 1.

  In accordance with the invention, the piercing of the teat comprises a slot 2 (which has been assumed to have a straight profile in order to simplify the representation, but which is advantageously established with a broken profile in order to facilitate the flow of relatively thick slurries), at each end of which is fitted a blind cylindrical cavity 3 which opens inside the nipple and the bottom, of very reduced thickness, is cut by radial slots 4, in number

  of three in the embodiment example envisaged.

  The central slot 2 has a lower part with a triangular profile.

  gular, which is extended upwards by a cutout 2 '. It will also be observed that the upper bottom of each cavity 3 is located at a very short distance from the external face of the nipple, so that the membranes or flaps delimited by the radial slots 4

  have a very reduced thickness.

  It is thus understood that one realizes, on either side of the slot 2-2 'intended for the normal passage of the spray mixture from the inside of the bottle.

  in the direction of the child's mouth, two sets able to behave

  ter in the manner of valves, which: effectively oppose any untimely expulsion of the liquid when the bottle is handled more or less roughly with the nipple turned substantially upward, allow, by means of the deformation of the flaps illustrated in fig 6, penetration of air into the bottle as it is emptied, when said bottle is used with the teat turned more or less obliquely downward and introduced into the

child's mouth.

  It will be noted that the cylindrical cavities 3 hold advantageously-

  instead of the circular section holes formed at the ends of the central slot of the known teats made of silicone, this hole having

  for the purpose of opposing the tearing of said central slot.

  It should also be understood that the above description has not

  given as an example and does not limit the area

  ne of the invention which we would not leave by replacing the details

  of execution described by all other equivalents.
