The flange portion 25 is located at an intermediate portion in the vertical direction of the milking connector 23, has a ring shape, is connected to the upper end portion of the insertion tube portion 24, and protrudes outward in the radial direction. The nipple is fixed between the upper end of the mouth 2B of the bottle body 1B of the second type baby bottle and the upper end of the nipple fixing ring 7.

The connection tube portion 26 constitutes the upper side of the milking connection member 23 and is in the form of a tube which communicates with the inside of the insertion tube portion 24 and opens obliquely upward and forward.
The connecting cylinder 16 of the milking cup 12 is removably inserted into the milking cup 12 from the inner peripheral portion of the milking cup 5 upward. In addition, the connecting cylinder 26
Is inclined at the same angle as the connecting cylindrical portion 16 of the milking cup 12 (inclined with respect to the vertical direction), and the axis thereof is the milking cup in FIGS. 1, 2 and 5. It is overlapped with the axis 17 of the twelve connecting cylinders 16 and intersects with the axis 27 of the insertion cylinder 24.

On the inner peripheral surface of the connecting cylindrical portion 26, inner peripheral ribs 31 located at four positions (a plurality of positions, three or more positions) at the front, rear, left and right sides thereof are equally spaced in the circumferential direction (substantially equally spaced in the circumferential direction). ). The inner circumferential rib 31 is formed over substantially the entire length in the axial direction (the entire length in the axial direction) excluding the upper end portion of the connection tubular portion 26, and protrudes radially inward in a semicircular shape. When the connecting tube 16 is inserted into the connecting tube 26,
As shown in FIG. 6, the outer peripheral surface of the connecting cylindrical portion 16 is
Line contact with 1. However, at the time of insertion, the inner circumferential rib 31
May be slightly elastically deformed, and the contact portion may be slightly larger than the line contact, or a slight gap may be formed between the outer peripheral surface of the connecting tubular portion 16 and the inner peripheral rib 31. .

In one example configured as described above, when the milking connector 23 is attached to the bottle 1A of the first type baby bottle, the nipple is removed from the mouth 2A of the bottle 1A. As shown, the insertion tube portion 24 of the milking connector 23 is inserted into the mouth 2A.

When the milking connector 23 is attached to the bottle body 1B of the second type baby bottle, the nipple fixing ring 7 is removed from the mouth 2B of the bottle body 1B, as shown in FIG. Thus, the insertion cylinder 24 of the milking connector 23 is inserted into the mouth 2B, and the flange 25 of the milking connector 23 is placed on the upper end surface of the mouth 2B. Next, the nipple fixing ring 7

After attaching the connection body 23 for milking to B, as shown in FIGS. 1, 2 and 5, the connection tube part 16 of the milking cup 12 is inserted into the connection tube part 26 of the connection body 23 for milking. Then, the milking set is attached to the bottles 1A and 1B.

At the time of milking, the bottles 1A and 1B are moved between the thighs of the obstetrics and women through an auxiliary tool (or towel, magazine, etc.).
In this state, pinch or place on a table, etc.
As shown in FIG. 2, the front edge of the opening edge of the milking cup 12 is in contact with the lower side of the maternal breast 35. Then, the mother rubs the breast 35 by hand and squeezes out breast milk, and stores the squeezed breast milk in the bottles 1A and 1B via the milking cup 12 and the milking connector 23.

In the above case, the connection tube portion 26 of the milking connector 23 and the connection tube portion 16 of the milking cup 12 are inclined forward, and the milking cup 12 projects forward from the bottles 1A, 1B. Therefore, when the bottles 1A and 1B are sandwiched between the thighs of the obstetrics and women, the bottles 1A and 1B can be easily sandwiched between the "portions near the knees" where the force is easily applied.

The front edge of the opening edge of the milking cup 12 is formed as a straight linear portion 21, and the contact portion with the lower side of the breast 35 is large. The protection member 14 made of an elastic material is externally fitted to the edge, and the inner peripheral rib 31 of the connection tube 26 or the elasticity of the entire connection tube 26 in the milking connection 23 made of the elastic material. Due to deformation or the like, the milking cup 12 can freely swing (swing) in any radial direction (any direction of 360 °) around the connection portion between the connection tube portion 16 and the connection tube portion 26. Therefore, the contact of the milking cup 12 with the lower side of the breast 35 can be made extremely soft, so that the maternity does not feel pain or the like during milking.

In the side view, the axis 17 of the connection tube 26 and the connection tube 16 is aligned with the opening direction 1 of the milking cup 12.
9, even if it is not inclined,
Even if the axis 17 of the connecting cylinder 16 is decentered with respect to the center of the opening 18 of the milking cup 12, the rotation of the milking cup 12 causes the opening 18 of the milking cup 12 to rotate.
And the positional relationship between the maternal nipples 36 can be adjusted.

By the way, if there is no inner circumferential rib 31 on the inner circumferential surface of the connecting cylinder 26 of the milking connector 23,
When the connection tube portion 16 of the milking cup 12 is inserted into the milking cup 12, the inner peripheral surface of the connection tube portion 26 and the outer peripheral surface of the connection tube portion 16 are, for example,
When the milking connector 23 is made of a material having a large coefficient of friction such as rubber in the case of surface contact over substantially the entire surface (entire surface), the frictional force between the connection tube portion 26 and the connection tube portion 16 becomes large, A large force is required for inserting / removing the connecting tube 16 into / from the connecting tube 26 and rotating the connecting tube 16 with respect to the connecting tube 26. However, in the present invention, the inner circumferential ribs 31 are arranged on the inner circumferential surface of the connection tubular portion 26 at equal intervals in the circumferential direction.
The connecting tubular portion 16 is connected to the connecting tubular portion 26 via the inner circumferential rib 31.
Is in line contact with (or in close contact with) the inner peripheral surface of the connecting cylinder portion 26, the frictional force between the connecting tubular portion 26 and the connecting tubular portion 16 is small, and the connecting tubular portion 16 can be inserted into and removed from the connecting tubular portion 26. The rotation of the connecting cylinder 16 with respect to the connecting cylinder 26 can be easily performed with a small force.

The inner peripheral rib 31 is provided on the inner surface of the connection tube 26 of the milking connection member 23 as described above, and its strength is increased. The milking cup 12 can be securely held.

Incidentally, at the opening edge of the milking cup 12,
Since both sides of the straight portion 21 are curved corner portions 22, the breast portion attached to the maternal nipple 36 can be scraped off by the corner portion 22 at the end of milking.
