Definitions

  • Improved baby bottle that includes an air valve located on the rigid body of the container, or optionally on an additional threaded device; which in its preferred embodiment will allow analog flow regulation by manually modifying the pneumatic flow resistance of the system.
  • the present invention fundamentally introduces the incorporation of a valve located on some of the solid parts of the bottle, which will generally be carried out in thermoplastic hydrophobic technical fabric.
  • said valve can be part of a screw-in device, capable of being adapted to a conventional bottle for infant feeding.
  • the purpose of said valve in both cases is to obtain beneficial effects in the process of ingesting milk or fluid food, thus avoiding the known colic of the infant.
  • the device according to the invention is intended to almost completely prevent undesirable entry of air through the suction hole, allowing air exchange by a valve or membrane independent of the nipple, and additionally maintaining constant pressure inside the container during the entire lactation process.
  • the present invention raises in one of its embodiments the possibility of modifying, by means of a simple manual operation, the reference value of the pressure inside the container, and thus allows analogically adjusting the conditions of the intake in order to achieve of a totally natural breastfeeding.
  • Another purpose of the invention is to allow simple hygiene and maintenance thereof, as well as to maintain the proper functioning of the valve regardless of the conditions of use and condition of the nipple.
  • SUBSTITUTE SHEET (RULE 26) to claim all those embodiments of bottles that, being absent from the valve, are instead provided with holes or openings whose clear purpose is the coupling of one or more valves of the type described herein.
  • the application of the particular physical characteristics (air permeability and water impermeability) associated with hydrophobic membranes, with small pore size or microperforation, to the area of the development of anti-colic valves for bottles, is the novel and original idea They share all the proposed accomplishments.
  • this document is intended to claim all that embodiment that, whether or not contemplated herein, applies, for the solution of infant colic, the particular physical principles of filtration mentioned herein.
  • the infant is forced to interrupt the suction and open the mouth to allow air to enter through the suction hole of the nipple.
  • This air mixes undesirably with the nutritional liquid, generating digestive problems that add to the discomfort caused by a process of discontinuous suction with forced pauses, very different from the instinctive process of natural breastfeeding.
  • the excessive intake of air associated with this annoying process of artificial feeding is almost exclusively responsible for the infant's known colic; and, additionally, the vacuum generated during suction can be transferred to the baby's ear causing fluid to enter the eustachian tubes, which increases the risk of otitis.
  • a prominent group of inventions (ES 2065048 T3, ES 1028589 U, ES 1030225 U, ES 1017343 U) consists of a collapsible and generally disposable container incorporated inside the outer rigid bottle container.
  • These solutions which jointly solve hygiene problems together with those associated with the formation of imperfect vacuum inside the container (and consequent risk of colic), however, have the disadvantage of being expensive in the long term. Indeed, in the increasingly frequent cases, in which the stage of breastfeeding is prolonged considerably, it is not interesting nor an excess of asepsis, which could stunt the child's immune system, nor of course the use of disposable materials that entail In addition to the aforementioned increase in economic cost, an unnecessary accumulation of waste, not recommended from the point of view of ecological sustainability.
  • Another group of inventions are those that have the anti-colic valve incorporated in the teat itself (ES 0291545 U), generally in the outer body thereof, or at its base.
  • the former have the disadvantage that if the child (think of children with sufficient independence to take the bottle by themselves) turns the head or the bottle slightly during intake, it deforms the valve so that, in a few cases it comes out She's the milk
  • these valves must be incorporated in radially asymmetric teats in which there is only a correct position of lactation, which is the one in which the valve is oriented upwards.
  • the last major group of inventions (ES 2166902 T3, ES 2094717 Tl, ES 1036158 U, ES 1037906 U), is one in which the solution to the hydrodynamic problem is approached through systems of pipes, valves or recesses more or less sophisticated, some of which even contain moving parts. All these inventions have two major drawbacks. The first is cleaning, since it is either expensive to access certain points of the pipeline system, or it is directly impossible. The second is maintenance, as these systems usually have delicate or fragile parts as well as bulky or prominent.
  • valves made from hydrophobic tissues such as ethylene polytetrafluoride (ePTFE), ethylene-ethylene chlorotrifluoride (HALAR®), or other polymers of similar characteristics.
  • ePTFE ethylene polytetrafluoride
  • HALAR® ethylene-ethylene chlorotrifluoride
  • valves containing ePTFE membranes prepared in the absence of PFOA 's, in compliance with current food regulations), or HALAR®, allows, in a really simple way, to achieve an almost perfect anti-colic effect.
  • the basic principle of filtration of these materials is that they offer minimal resistance to the flow of air through it, and on the contrary they impose a high resistance to the flow of hydrophilic fluids. If we take into account that the technical difficulty to be solved is to allow the entry of air inside the bottle and prevent the outflow of fluid, it is easy to conclude that the constructive possibilities of bottles with ePTFE valves, HALAR will be many and simple ®, or similar.
  • valves and vessels are sold separately.
  • the first one consists of a ring with an inner diameter equivalent to the inside diameter of the threaded neck of the bottle container, which in its lower part is provided with a female thread to adapt to the bottle's neck and in its upper part it has a male thread to allow it to be adapted a nipple with conventional thread.
  • the size of each thread will be variable to suit most or all manufacturers in the market, the present invention not being limited to a single thread diameter.
  • This ring contains the necessary pipes to allow sufficient air flow from the outside to the valve that communicates with the "wet" part of the system.
  • the latex in its usual form, the silicone, either in its usual form or with a micropore system taking advantage of its highly hydrophobic character
  • valves, membranes or tissues of hydrophobic fibers with a micropore size that allows both adequate asepsis and a simple suction process.
  • fabrics composed of ePTFE or Halar fibers is advised.
  • the fixing of these valves can be carried out in different ways according to the chosen embodiment, such as welding, simple insertion by pressure or by threading.
  • a threaded washer would be required for the valves in latex, silicone or ePTFE (not necessary in all cases, since a simple disc could be provided whose exterior is a self-supporting elastic ring, or it could be inserted "under pressure”"a valve of the type expressed in Figure 10 (38), or simply weld the entire valve, the membrane, or the filter tissue, if it consists of thermoplastic material.
  • SUBSTITUTE SHEET (RULE 26) that replacing said element with a fixed ring will be a particular case contemplated in the present invention.
  • the proposed design for this mobile ring in the preferred embodiment allows to modify the absolute resistance to the air inlet flow according to a continuous function, but with discontinuous gradient. In this way we can obtain, in a simple way, for a given value of the suction force, any flow value in a wide range that extends from practically zero to a characteristic value that will be determined by the state of conservation of the valve arranged at the "wet" end.
  • the present invention refers to a threaded device adaptable to bottles, which could continue to be used (with worse behavior) without the participation thereof.
  • This provides a particular advantage over other systems, and its use is optional, the bottle being functional with or without the provision of the proposed invention.
  • a simplified version of the proposed system could be fixed in a fixed way directly to the bottle container, although the fact that the device is independent, presents another series of advantages besides the one mentioned, among which we highlight the following: ) the cleaning of both the device and the container is simplified b) in case of having children of an advanced age or less demanding we can give up the use of the ring at will, c) the situation in the upper part of the bottle allows that in transport the system stays dry
  • SUBSTITUTE SHEET (RULE 26) d) it is also allowed to incorporate a cap between the fluid of the bottle and the valve or membrane that is the most delicate part of the system, and the only fungible in some embodiments, thus extending the useful life of these elements e) finally, maintaining the uniformity of the internal pressure of the vessel is all the more effective the closer to the outlet orifice the valve is arranged, as discussed in the following paragraph.
  • the hydrodynamic study of the complete system during breastfeeding shows that, except for some initial sips in which the suction resistance is slightly lower, and the final sips, characterized by "dry" work of the valve porous; in the rest of the suction the relationship between the suction force and the flow rate obtained is strictly constant, and almost completely independent even of the angle at which the baby arranges the bottle.
  • the justification for this statement is simple: i) At the beginning of suction, the pressure in the air of the container is atmospheric, so that when tilting the bottle for breastfeeding, the highest point of the liquid is at that pressure, and thus The pressure at the end of the nipple will depend on the height of the fluid according to the known fundamental equation of hydrostatics.
  • the baby makes a very slight vacuum in the air of the bottle that will vary depending on the liquid remaining in the container, thus the reference point (whose pressure will be constant and equal to the Atmospheric minus hydrodynamic load losses in the valve) is located on the wet side of the valve itself.
  • valves of the wet end of the pneumatic pipe can be replaced, since their useful life and economic cost will be predictably lower than that of the main body.
  • cleaning of the entire system is carried out by immersing it in a sterilizing liquid; This would not cause any problems, even if the pneumatic ducts were not completely dry at the time of artificial feeding. Indeed, the
  • SUBSTITUTE SHEET (RULE 26)
  • the morphology of the preferred embodiments is such that a slight shaking of the system would suffice, as it is removed from the sterilizing liquid to remain functional, since when the position of the bottle is reversed during breastfeeding, the dry side of the valve is effectively dried by gravitational effect. and therefore would behave correctly.
  • the purely pneumatic circuit ducts (with the exception of both initial and final valves) are oversized, so that if their section is reduced by the presence of drops of sterile liquid, the system continues to function normally.
  • the proposed invention allows, when incorporated into a conventional bottle, to have an improved bottle system that has the following advantages over current systems a) As it is a multi-use bottle, it resolves, compared to bottles with a container disposable, the problems discussed above related to a lower economic and ecological impact b) By untying the valve nipple, it can be used together with any type of nipple without being limited to radially asymmetric or those designed for a single format container. c) The valve and nipple disengagement also allows, in case of wear, that only the damaged part is replaced. This advantage may seem minor, however, in practice, it is common for children to "fondle" certain teats going through a long and annoying period of adaptation each time it is replaced.
  • the present invention allows a slight regulation of the suction resistance, by means of the analog seal of the pneumatic duct. This regulation can facilitate, among other things, the process of adapting the child to a new nipple with a different hole size, adapting the suction in case of milk or food with the same nipple (for example on trips), or simply look for the optimal point in each moment for the well-being of the baby.
  • any additional device is claimed, whose purpose is to adapt to bottles for their improvement, and in whose elaboration valves are used that contain ePTFE, HALAR, or other hydrophobic polymers of similar physical characteristics that use the same physical principles mentioned in the previous paragraph to allow the entry of air without fluid outlet.
