Description

    The present invention is a valve structure for a drinking mouth that enables both a peristaltic movement and a suction movement for an infant to take a drink.

    Conventionally, a drink or a straw is used for ingesting a beverage, and suction is performed by sucking. However, infant feeding is performed by the peristaltic movement of the infant's tongue with the nipple positioned on the infant's upper jaw, and the infant has not performed a suction movement from the beginning. For this reason, in the transition period from breastfeeding to drink intake, infants have a problem that it is very difficult to take drinks and they cannot handle artificial nipples etc., and many drinking mouths for training are used. ing.

    These drinking mouths have been improved. A valve structure has been proposed that is used by infants and the like with reduced suction force, can prevent the backflow of the beverage, holds the beverage at the mouth of the user, and facilitates suction from the second time. (See Patent Document 1)

    Moreover, when ingesting a drink, this inventor proposed the valve | bulb structure body joined and used for a user's mouth part so that the user with which the attraction | suction power fell might be easy to attract. This valve structure is a simple structure using a soft valve member, and has the ability to assist suction movement by pressing with a tongue or teeth. (See Patent Document 2)

JP2001-301 JP2009-159445A

    The valve structure proposed in Patent Document 1 is used by being connected to a straw or the like, and is an improvement in which a user whose suction power is reduced by holding a beverage near the user's mouth is easy to suck. is there. However, there is no change in the assumption of the suction luck.

    Moreover, although it is patent document 2 which is a proposal of this inventor, the features, such as a soft valve member, apply the flow pressure of the drink by the user who the suction force fell using the tongue, teeth, etc. Although effective, it does not exceed the scope of improvement based on suction motion.

    During the lactation period, infants perform a peristaltic movement of the tongue, which is a reflex movement, and ingest breast milk or milk from the nipple or artificial nipple. This exercise is swallowing the nipple or milk by moving the tongue back and forth with the mouth open. They are not sucking. Although there are individual differences, from about 5 to 6 months of age, the unconscious movement of the tongue gradually shifts to a suction movement that integrates the conscious lips, tongue, gums, teeth, jaws and cheeks. Go. The suction movement must be acquired by the infant, and is accompanied by great difficulties such as mess and spillage. However, the current training products are not enough. Even when the tongue is moved, the vertical movement is added from the front and back movement, and the left and right movements are added. Furthermore, complex and delicate movements involving lips, teeth, jaws and cheeks that are linked to breathing are required.

  The present invention has been made in view of the above, and has developed the valve structure used by a user with weak suction force proposed by the present inventor to smoothly perform a transition from a peristaltic motion to a suction motion.

    In addition, the present invention is a valve structure for a drinking mouth, and naturally it is possible to prevent the reverse flow of the beverage, and not only does it not allow the beverage to be ingested by a peristaltic-like exercise, but also does not disturb the suction exercise. The ability to perform peristalsis-like movements and suction movements at the same time has gained the ability to serve as a drinking mouth for ingestion of beverages during the transition period from early childhood to early childhood.

    In addition, the valve structure for the drinking mouth of the present invention is configured such that the cross-sectional areas of the beverage outlet port 3a, the beverage channel port 3b, the beverage channel port 3c, and the beverage channel port 3d through which the beverage passes are the valve structure 2a and the valve structure. Since the cross-sectional area of the body 3a is changed from 5% to 20%, and the cross-sectional area is set to the beverage outlet port 3a ≧ the beverage channel port 3b ≧ the beverage channel port 3c ≧ the beverage channel port 3d, the flow of the beverage is made smooth. I was able to. Furthermore, the effect of preventing the backflow of the beverage could be improved.

    Further, the valve structure for the mouth of the present invention enables an infant to ingest a beverage by a peristaltic movement, and further, it is necessary to lift the beverage container so that the infant uses an artificial nipple or the like. And a valve structure that can handle any posture of infants.

    Although it is an Example which shows the form of this invention, as long as it does not impair the technical idea of this invention, it should just be and does not specify or limit to this Example.
