Description

  The present invention relates to a beverage container having a mouthpiece adapter attached to an opening of a cap.

  There is a great difference in the behavior of the infant between the stage where the infant ingests the beverage from the nipple of the baby bottle by peristaltic movement and the stage where the infant ingests the drink from the straw. Then, the drink container provided with the suction mouth part applied in the transition period of those steps is proposed. For example, a first adapter having a mouth portion having a substantially elliptical cross section and a second adapter having a mouth portion having a substantially circular cross section are prepared, and the mouth portion of the second adapter is provided inside the mouth portion of the first adapter. The shape of the mouthpiece can be adjusted according to the growth of the infant by making it possible to use both the state in which both adapters are attached to the opening of the cap in an overlapping manner and the state in which only the second adapter is attached to the opening of the cap. A beverage container that can be changed has been proposed (see Patent Document 1). In addition, there is Patent Document 2 as a prior art document related to the present invention.

Japanese Patent No. 4086174 JP 2002-321755 A

  In the technique of Patent Document 1 described above, since there is a relationship in which the mouth portion of the second adapter is fitted inside the mouth portion of the first adapter, the size of the mouth portion of one adapter depends on the size of the mouth portion of the other adapter. Limited. That is, the outer diameter of the second adapter can only be set to a value equal to or less than the value obtained by subtracting the thickness of the suction port from the short diameter of the suction port of the first adapter. Therefore, for example, when the short diameter of the mouthpiece portion of the first adapter is optimized for an infant of the age to which the first adapter should be applied, there is a possibility that a sufficient outer diameter cannot be given to the mouthpiece portion of the second adapter. On the other hand, if the outer diameter of the mouthpiece of the second adapter is optimized, the minor diameter of the mouthpiece of the first adapter may become excessively large.

  Therefore, the present invention can use a plurality of mouthpieces properly, gives each mouthpiece the optimum size and hardness, promotes the development related to infant lip closure, and suppresses the forward protrusion of the tongue to suppress moisture. An object of the present invention is to provide a beverage container capable of wearing lip and tongue movements suitable for ingestion.

The beverage container (1) of the present invention has a container body (2) for containing a beverage and a cap (3) for closing the container body, and the cap is provided with an opening (3d), and the opening A plurality of mouthpiece adapters (10, 20) can be alternatively attached to the portion, and each of the plurality of mouthpiece adapters can be fitted around the opening of the cap. A base (11, 21); a mouthpiece (12, 22) projecting from the base beyond the opening to the outside of the cap; and a suction hole communicating with the inside and outside of the beverage container through the base and the mouthpiece (15, 25), and the plurality of mouthpiece adapters include a first mouthpiece adapter (10) in which a section of the mouthpiece portion is substantially elliptical, and a section of the mouthpiece portion is substantially circular. the second suction port adapter (20) and includes a, Each sucker portion of the serial first suction port adapter and the second suction port adapter is molded integrally with the base portion in quantitative protruding state from the base, the mouthpiece portion of the first suction port adapter, the suction The solid structure has no space except for the hole, and the inner diameter (D1) of the suction hole of the first suction adapter is larger than the outer diameter (d2) of the tip of the suction part in the second suction adapter . Is also set smaller.

  According to the beverage container of the present invention, since a plurality of mouthpiece adapters can be selectively attached to the common opening of the cap, the shape or size of the mouthpiece portion of each mouthpiece adapter is the mouthpiece portion of another mouthpiece adapter. Not affected. Therefore, the shape and size of the mouthpiece portion of each mouthpiece adapter can be optimized according to the purpose. Since the mouthpiece portion of the first mouthpiece adapter has a substantially elliptical cross section and the second mouthpiece adapter has a substantially circular cross section, for example, for users who do not have sufficient muscle group development related to lip closure, etc. The mouthpiece part of the first mouthpiece adapter is applied, and switching to the mouthpiece part of the second mouthpiece adapter according to the development of the muscle group is possible. Moreover, since the suction portion of the first suction adapter has a solid structure with no space except for the suction holes, it is easy to ensure rigidity, and the inner diameter of the suction holes provided in the first suction adapter is the first. It is smaller than the outer diameter of the suction part of 2 suction adapters. Thereby, it is possible to selectively use a plurality of mouthpieces, which cannot be realized with a conventional beverage container that requires the mouthpieces to be overlapped.

  In the beverage container of the present invention, the short diameter (d1) of the mouthpiece portion of the first mouthpiece adapter may be set larger than the outer diameter (d2) of the mouthpiece portion of the second mouthpiece adapter. Projection amounts (h1, h2) from the caps of the respective suction portions of the first and second suction adapters may be set to 18 mm or less. The inner diameter (D1) of the suction hole of the first suction adapter may be in the range of 1 to 4 mm. The outer diameter of the inlet portion of the second inlet adapter may be 7.2 mm or more. Furthermore, at least the suction port portion of the first and second suction adapters may be made of an elastic material. Each of the inlet portions of the first inlet adapter and the second inlet adapter may have a tapered shape in which the cross-sectional area gradually decreases toward the tip. The technical significance of these aspects will be clarified by referring to the embodiments of the present invention described later.

  In addition, in the above description, in order to make an understanding of this invention easy, the reference sign of the accompanying drawing was attached in parenthesis, but this invention is not limited to the form of illustration by it.

  As described above, according to the beverage container of the present invention, since a plurality of mouthpiece adapters can be selectively attached to the common opening of the cap, the shape or size of the mouthpiece portion of each mouthpiece adapter is It is not affected by the inlet part of other inlet adapters. Therefore, the shape and size of the mouthpiece portion of each mouthpiece adapter can be optimized according to the purpose.

  1A and 1B are cross-sectional views of a main part of a beverage container according to an embodiment of the present invention, and FIGS. 2A and 2B are perspective views of the beverage container. The beverage container 1 is intended for infants and, more specifically, a transition between a step of ingesting a beverage by a peristaltic movement from a nipple of a baby bottle and a step of ingesting a beverage through a straw-type mouthpiece. It is adapted for use in the season. The beverage container 1 includes a container body 2 and a cap 3. The container body 2 is formed in a cup shape having an opening 2a at the upper end, and a beverage is accommodated therein. The cap 3 is attached to the container main body 2 so as to close the opening 2 a by engaging a female screw portion 3 a formed on the inner periphery of the lower end portion with a male screw portion (not shown) on the outer periphery of the upper end of the container main body 2.

  As shown also in FIG. 3, a bulging portion 3b is formed on one side across the center of the cap 3, and a substantially flat receding portion 3c that is one step lower than the bulging portion 3b is formed on the other side. A substantially elliptical opening 3d is formed in the bulging portion 3b, and a substantially circular retaining hole 3e is formed in the retreating portion 3c. On the outer periphery of the cap 3, a plurality of convex portions 3 f that are to be finger-hooked when the cap 3 is rotated with respect to the container body 2 are formed at appropriate intervals in the circumferential direction.

  The first suction adapter 10 shown in FIG. 1A and the second suction adapter 20 shown in FIG. 1B are alternatively attached to the opening 3d. As shown in FIGS. 1A and 4A, the first suction adapter 10 includes a base portion 11, a suction portion 12 protruding from the surface of the base portion 11, and a stopper connected to the outer periphery of the base portion 11 via a belt 13. And a through hole-like suction hole 15 that penetrates the base 11 and the suction port 12 and opens to the upper and lower surfaces of the suction adapter 10. On the outer periphery of the base portion 11, a groove portion 11 a that goes around the base portion 11 is formed. A flat base body 11b having an oval outer periphery is formed below the groove 11a of the base 11, and a substantially elliptical flange 11c is formed above the groove 11a. The flange 11c is somewhat smaller than the base body 11b. The belt 13 is connected to the base body 11b.

  The suction port 12 projects substantially vertically from the surface of the flange 11c. The cross section of the suction port 12 (the cross section in the direction crossing the suction hole 15) is substantially elliptical. The outer peripheral surface of the suction port 12 is tapered so that the cross-sectional area of the suction port 12 decreases toward the tip of the suction port 12 (the upper end in FIG. 1A). However, the outer peripheral contour of the cross section at an arbitrary position of the suction port 12 is similar to the outer peripheral contour of the cross section at other positions. The suction port 12 has a solid structure in which no space exists except for the suction hole 15.

  As shown in FIGS. 1B and 4B, the second suction adapter 20 includes a base 21, a suction part 22 protruding from the surface of the base 21, and a stopper connected to the outer periphery of the base 21 via a belt 23. And a through hole-like suction hole 25 that opens through the upper and lower surfaces of the suction adapter 20 through the base part 21 and the suction part 22. The base portion 21 has the same shape as the base portion 11 of the first suction adapter 10, and has a groove portion 21 a that goes around the base portion 21, a base body 21 b that is positioned below the groove portion 21 a of the base portion 21, and an upper side of the groove portion 21 a. And a substantially elliptical flange 21c. The size of the base 21 is also equal to that of the base 11. Further, the belt 23 is connected to the base body 21b, and the stopper 24 is the same shape and size as the stopper 14.

  The suction port 22 protrudes substantially perpendicularly from the surface of the flange 21c. The cross section of the suction port 22 (cross section in the direction crossing the suction hole 25) is substantially circular. The outer peripheral surface of the suction port 22 is tapered so that the cross-sectional area of the suction port 22 decreases toward the tip of the suction port 22 (the upper end in FIG. 1B). However, the outer peripheral contour of the cross section at an arbitrary position of the suction port 22 is similar to the outer peripheral contour of the cross section at other positions. The suction port 22 has a solid structure with no space except for the suction hole 25.

  The first suction adapter 10 is configured such that the flange 11c of the base 11 is exposed to the surface of the cap 3 and the suction mouth 12 is connected to the cap 3 by fitting the groove 11a of the base 11 to the inner periphery of the opening 3d of the cap 3. It is attached to the cap 3 so as to protrude obliquely upward. The base body 11 b and the belt 13 are accommodated in the cap 3. The stop portion 14 is fitted into the stop hole 3e of the cap 3 from the inside of the cap 3, thereby giving the suction adapter 10 an effect of preventing the cap adapter 3 from falling off. Even when the second suction adapter 20 is mounted instead of the first suction adapter 10, the base 21 and the stopper 24 may be fitted to the cap 3 in the same manner as described above.

When the beverage container 1 is used in the transition period described above, the first mouthpiece adapter 10 is used first, and then the second mouthpiece adapter 20 is used. The reason is as follows. If the transition from the beverage intake phase with peristaltic movement to the beverage intake phase with a straw is rapid, the infant may be confused about its intraoral movement, and may give a false response such as sticking out the tongue even if a straw is applied. . For this purpose, it is necessary to suppress confusion in the intraoral movement by pressing the tongue at the mouthpiece. In addition, it is necessary to close the lips when drinking beverages through a straw, but at the beginning of the transition period, the muscle groups related to lip closure in infants are not sufficiently developed. It is necessary to provide a mouthpiece that promotes muscle group development. Therefore, in the initial stage of the transition period, first cross-sectional shape by applying the mouthpiece portion 12 of the substantially elliptical shape, thereby holding down the tongue, and suck the suction port 12 relatively reasonably even infants muscle groups is underdeveloped To be able to. Next, at the stage where muscles related to lip closure have developed to some extent, the mouthpiece 22 of the second mouthpiece adapter 20 having a substantially circular cross-sectional shape is provided, and the transition to the beverage intake stage by a general straw is performed. To smooth.

  In order to adapt to the above purpose, it is desirable to set the dimensions of the adapters 10 and 20 as follows. First, regarding the mouthpiece portion 12 of the first mouthpiece adapter 10, the tip width W (major axis) shown in FIGS. 1A and 2A is 20 mm, the minor axis d1 is 9 mm, and the protrusion amount h1 is 18 mm or less (an example). As 17 mm). On the other hand, with regard to the mouthpiece 22 of the second mouthpiece adapter 20, the outer diameter d2 of the tip shown in FIGS. 1B and 2B is 7.2 mm or more (8.2 mm as an example), and the protrusion amount h2 is 18 mm or less (one example). As 17 mm). The outer diameter d2 is larger than 5.9 mm which is the outer diameter of the straw for infants and smaller than the minor diameter d1 of the mouthpiece portion 12 of the first mouthpiece adapter 10. Thereby, the suction port portion 22 can function as a means for facilitating the transition to the straw. Further, the protrusion amount 18 mm is smaller than the protrusion amount 29.2 mm of the infant straw. Thereby, as described above, the tongue of the infant can be pressed by the mouthpieces 12 and 22 to suppress confusion in the oral cavity. Further, the inner diameters D1 and D2 of the suction holes 15 and 25 are preferably set to a range of 4 mm at the maximum and 1 mm at the minimum. By setting the inner diameters D1 and D2 of the suction holes 15 and 25 in such a range, it is difficult to make a drink and the development of muscle groups related to the lip closure of infants can be promoted.

  Furthermore, since the suction port portion 12 of the first suction adapter 10 has a solid structure with no space except for the suction hole 15, it is difficult for an infant to collapse, and the inner diameter D 1 of the suction hole 15 is reduced. Even if it is set to a minimum of about 1 mm, there is no possibility that it will be blocked during use. The inlet adapters 10 and 20 can be made of various elastic materials, but silicon may be used as a material as an example. In that case, the hardness of silicon is preferably about 40 when measured according to K6253 durometer type A of Japanese Industrial Standard (JIS). This standard is a standard consistent with ISO7619. Note that it is sufficient that the mouthpieces 12 and 22 are elastic materials, and the bases 11 and 21 and the like may be rigid bodies integrally formed with the mouthpieces 12 and 22 using an insert molding method.

  The present invention is not limited to the form described above, and can be implemented in an appropriate form. For example, the number of inlet adapters is not limited to two, ie, the first and second inlet adapters 10 and 20, and an appropriate number of three or more may be prepared. For example, even if a mouthpiece adapter having a mouthpiece portion whose cross-sectional shape is closer to a circle than the mouthpiece portion 12 of the first mouthpiece adapter 10 is prepared between the first mouthpiece adapter 10 and the second mouthpiece adapter 20. Good. A mouth adapter having a mouth portion with a substantially circular cross section having an outer diameter smaller than the mouth portion 22 of the second mouth adapter 20 and larger than a general straw may be further prepared. Alternatively, a further suction adapter in which the outer diameter of the second suction adapter 20 is the same as that of the suction portion and the inner diameter of the suction hole is enlarged may be prepared.

  The base part of the mouthpiece adapter is sufficient if it can be attached to the common opening of the cap, and it is not always necessary that the base parts have the same shape and size between the mouthpiece adapters. The beverage container of the present invention is not limited to those applied to the above-mentioned transition period of infants and can be applied as long as it is a beverage container having a plurality of types of desired shapes or dimensions of the mouthpiece. For example, the present invention can also be applied to a beverage container for rehabilitation when a muscle group related to lip closure is damaged. The present invention can also be applied to the case where the mouthpiece is properly used depending on the type of beverage.
