Description

[Detailed description of the invention]

[0001]

[Technical field of invention]

 The present invention relates to a nipple worn on a baby bottle or the like.

[0002]

[Prior art and problems]

 The elastic nipple 3 attached to the opening of the baby bottle 1 by the cap 2 has a suction portion 31 formed in a substantially nipple shape and a nipple main body 32 connected to the suction portion 31. The nipple main body 32 is attached to the opening of the baby bottle 1 by the cap 2 and includes a circular flange 321 and a trunk portion 322 erected by the flange 321 and connected to the suction part 31. . The body part 322 is in a state narrower than the bottom of the suction part 31. A suction passage 33 communicating with the inside of the baby bottle 1 is formed in the suction part 31 and the nipple main body 32, and the contents in the baby bottle 1 are passed through a suction port 34 formed in the suction part 31. , Can be sucked.

The nipple 3 is fixed to the cap 2 by fitting the constricted torso portion 322 into an opening formed at the center of the cap 2, and is further screwed into a screw formed at the tip of the baby bottle 1. Thereby, it is detachably attached to the baby bottle 1.

In order to suck the contents in the baby bottle 1, it is necessary to enter air into the baby bottle 1. In order to allow such air to flow, an intake valve is provided in the flange 321. 35 are formed.

The suction port 34 is generally in the shape of a circular hole, and is divided into three types, large, medium and small, according to the suction force. A nipple in which the suction port 34 is a cut is also known. The suction port 34 of the nipple 3 is formed of an X-shaped cut or a Y-shaped cut as shown in FIG. In the case of such a cut, since the opening size of the suction port 34 changes due to the suction force and the flow rate can be controlled, unlike the round hole-shaped suction port 34, it is not necessary to form a large, medium, and small cut. Was thought.

However, theoretically, as described above, the opening size of the cut changes linearly depending on the magnitude of the suction force, but in practice this is not the case, and the content in the baby bottle 1 is large. The drawback is that it is sucked in or is too small. In addition, when the contents are somewhat viscous, such as milk, and when the contents are not viscous, such as water, the amount of suction changes drastically, and a single cut size cannot be used.

[0007]

[Purpose of the invention]

 The present invention has been made in view of the above-described problems, and has as its object to provide a nipple in which an appropriate amount of contents is sucked in a nipple having a notch in a suction port.

[0008]

[Means for solving the problems]

 In order to achieve the above object, according to the nipple according to the present invention, in the nipple having a suction portion formed with a suction port for suction at a tip thereof and a flange for attaching to a baby bottle, the suction port is cut into a notch. The cut has a different size in accordance with the suction force.

According to the present invention, since the size of the cut is changed in accordance with the suction force in the nipple having a cut in the suction port, an appropriate amount of contents can be obtained by selecting a nipple having an appropriate cut size. Has the advantage that it can be sucked.

【Example】

 According to the nipple of the present invention, as in the prior art, the nipple comprises a suction portion 31 having a substantially nipple shape and a nipple main body 32 to be attached to the opening of the baby bottle 1. The nipple main body 32 has a torso portion 322 fitted into the opening of the cap 2, and a flange 321 sandwiched between the cap 2 and the opening of the baby bottle 1. It is connected to the bottom and has a structure erected by a circular flange 321 extending in the horizontal direction. The torso portion 322 has a diameter smaller than the diameter of the bottom of the suction portion 31 in this embodiment, so that the torso portion 322 forms a constriction. A suction passage 33 communicating with the inside of the baby bottle 1 is formed in the suction part 31 and the nipple main body 32 so that the contents in the baby bottle 1 can be sucked through a valve formed in the suction part 31. It has become.

The flange 321 is formed with an inhalation valve 35 projecting inward of the baby bottle 1, and the inhalation valve 35 penetrates through the front and back surfaces of the flange 321 to allow air to flow. . In this embodiment, the suction valve 35 is provided at an arbitrary position on the circumference of the flange, forms a hemispherical hollow projection 351 on the lower surface of the flange, and is provided at the tip 352 of the projection 351. It has a-, X- or Y-shaped cut so that the inside of the baby bottle 1 and the upper part of the flange 321 communicate with each other.

A suction port 34 is formed at the tip of the suction section 31. The suction port 34 is X-shaped in this embodiment, but may be Y-shaped or −-shaped. In the present invention, the notch dimension L differs from L1, L2, L3 depending on the suction force or the contents. In other words, an infant with a small suction force uses an L1 nipple with a large incision size, while an infant with a large suction force uses an L3 nipple with a small incision size. Infants with suction force in between use L2 nipples with intermediate cut dimensions. By selecting nipples having different cut dimensions L depending on the suction force or the contents of the baby bottle 1 in this manner, it becomes possible to suck an appropriate amount of the contents.

In this embodiment, the X-shaped cut has been described, but the same applies to a Y-shaped or a -shaped cut.

In the present invention, from the suction valve 35 formed on the flange 321, the body part 322 is raised toward the center of the circumference of the circular flange, and the bottom of the suction part 31 is brought into contact with the center of the nipple body 32. It has an air groove 4 that extends outward in the opposite direction and reaches the side surface of the suction portion 31. Therefore, the air groove 4 has an opening 41 above the cap 2. That is, the air groove 4 allows the suction valve 35 to communicate with outside air (see FIGS. 2 and 3). For this reason, there is an advantage that even if the cap 2 is screwed tightly to improve the adhesion of the flange 321 to the opening of the baby bottle 1, the flow of air is not hindered.

In the present invention, the cross-sectional shape of the air groove may be U-shaped, V-shaped, semi-circular or any other shape. As for the dimensions of the cross-sectional shape, the depth is 0. 2 to 0.8 mm, and its width is 1 to 3 mm. If the depth is less than 0.2 mm, it may be crushed by the fixture during sealing and the gap may be lost, and if it exceeds 0.8 mm, the contents may leak. In the case of the V shape, the length of one side of the isosceles triangle in cross section is 1.2 to 3.0 mm, and the central angle thereof is 45 to 100 degrees. If the temperature is less than 45 degrees, the nipple may be cracked and the washing becomes difficult. In the case of a semicircle, its radius is 0.4-1.5 mm. If it is less than 0.4 mm, the air supply is insufficient, and if it is 1.5 mm, there is a possibility of milk leakage.

Here, as shown in FIG. 2, the edge of the flange forms a rising end 323 having a triangular cross section. The seal end 21 of the cap 2 connecting the nipple main body 32 to the baby bottle 1 also has an inverted triangular cross section, so that the flange 321 of the nipple main body 32 is sealed from above.

The rising end 323 of the rim of the flange of the nipple 3 and the sealing end 21 of the mounting tool interact with each other when the nipple is attached to the baby bottle, thereby forming a ring-shaped hermetically sealed space. It is a relationship that gives the character. And, despite this sealing structure, the air groove 4 enables the supply of air to the baby bottle.

Here, the material of the nipple is silicone rubber or other rubber, and it is necessary that the rubber be highly safe especially for infants and infants. The rubber of the nipple preferably has a JIS hardness of 25 to 35. If the hardness is 25 or less, the nipple is easily deformed, and if the hardness is 35 or more, it is difficult for infants to suck.

[Effect of the invention]

 As described above, according to the nipple according to the present invention, in the nipple where the suction port is a cut, the size of the cut is changed in accordance with the suction force, so that a nipple having an appropriate cut is selected. This has the advantage that an appropriate amount of contents can be sucked. In addition, by forming an air groove communicating with the outside air from the suction valve, the contents can be sucked well without leaking.
