Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cap of a breast milk cryopreservation bag for cryopreserving breast milk.

[Prior Art] In recent years, due to the widespread use of refrigerators with freezer compartments, breast milk left unfed by infants is frozen and stored in the refrigerator, thawed when necessary, and warmed up to a predetermined temperature (about 40 ° C) before feeding Is being done.

2. Description of the Related Art Conventionally, when storing breast milk in a frozen state, a baby bottle or other sealable bottle container is often used as a storage container. However, the present inventor has come to the conclusion that the container having the form as shown in FIG. 5 is excellent in freezing property, storability and the like.

This cryopreservation container is made of a plastic bag body 1, a plastic mouth member 2 that is closely fixed to the opening of the bag body 1, and a plastic member that is attached to the mouth member 2 to close the opening. It is composed of a cap 3.
The cap 3 is provided with a tubular body portion 5 that is provided with an annular retaining projection 4 that is engaged with the outer peripheral edge of the mouth member 2 to prevent the cap member 3 from coming off.
An end surface portion 6 that is continuous with the tubular portion 5 and closes the opening side of the mouth member 2 is formed.

When thawing frozen milk, for example, a thawing container 7 as shown in FIG. 6 is used. This thawing container 7
It has an inner tank 9 and an outer tank 10 which are formed by being partitioned by a cylindrical partition 8, and water is injected into the inner tank 9 and the outer tank 10 has a temperature of 90 ° C.
Injecting some boiling water. Then, the frozen stored milk is soaked in water in the inner tank 9 as it is in a storage bag, and the frozen milk is gradually thawed by the water in the inner tank 9 warmed by the hot water in the outer tank 10, and further, 40 ° C. The baby is warmed to a certain degree and is fed.
In this way, by gradually thawing the frozen milk with a thaw container having a two-tank structure, it is possible to thaw without destroying or damaging the components of the milk.

[Problems to be solved by the invention] However, in such a breast milk freezing storage bag,
In order to improve storage stability, the air is removed as much as possible, the cap is capped, and the cap is put in the freezer and laid sideways to freeze it. A lump (the cross hatched area shown in Fig. 5 and 6) is formed. In this way, if a large block of ice forms in one place, the freezing of that part will not be melted easily with lukewarm water in the inner tank 9, and it will take a long time to thaw the entire frozen breast milk and raise it to a predetermined temperature. There was a problem that

The present invention has been made in view of such problems,
The cap has an inner cylinder that is inserted to the bottom of the mouth member.
The object of the present invention is to solve the above problems by reducing the size of ice formed in the vicinity of the mouth member as much as possible.

[Means for Solving the Problems] In order to achieve the above object, a breast milk cryopreservation bag cap according to the present invention is a breast milk in which a cylindrical mouth member is closely fixed to an opening of a bag body for storing breast milk. A cap to be attached to the mouth member of a cryopreservation bag, the inner cylinder portion projectingly formed in the central portion so as to be fitted to the bottom of the hole of the mouth member, and to be concentric with the inner cylinder portion. An outer cylinder part provided integrally with the inner cylinder part is provided on the outer peripheral surface of the inner cylinder part with an annular seal ridge that is pressed against the inner peripheral surface of the mouth member to seal the inner peripheral surface of the outer cylinder part. Is characterized in that an annular retaining ridge is provided which is engaged with the outer peripheral edge of the mouth member and prevents the mouth member from coming off.

[Operation] When the cap is attached to the mouth member, the bag body is grasped to raise the liquid level of the breast milk to the lower part of the mouth member, and in that state, the inner tubular portion is inserted into the opening of the mouth member, and The tubular portion is engaged with the outer peripheral edge of the mouth member. As a result, the seal ridge provided on the outer peripheral surface of the inner tubular portion is pressed against the inner peripheral surface of the mouth member, and the retaining ridge provided on the inner peripheral surface of the outer tubular portion engages with the outer peripheral edge of the mouth member. Therefore, it is possible to reliably prevent the cap from coming off while ensuring the sealing performance.

In this state, when the freezing storage bag for breast milk is frozen in the freezer compartment of the refrigerator, the inner cylinder part of the cap is inserted into almost the entire hole of the mouth member, so the size of the ice formed near the mouth member is reduced. Can be made smaller. Therefore, even lukewarm water can be thawed relatively early, and the baby can be fed without damaging the components of the breast milk stored frozen.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

1 to 4 are views showing an embodiment of the present invention.

First, the structure will be described. In the figure, 11 is a vinyl bag body, 12 is a plastic mouth member, and 13 is a plastic cap.

The bag body 11 is formed by heat-sealing and closing one end of a continuous tubular body, the mouth member 12 is inserted into the opening, and the mouth member 12 and the opening are formed by an adhesive means such as heat welding. It is fixed tightly around the entire circumference. The mouth member 12 is a hole
A ring-shaped cylindrical shaft portion 14 having 12a and fitted in the opening portion
And a flange portion 15 provided outward at one end of the cylinder shaft portion 14.

The cap 13 attached to the mouth member 12 includes an inner cylindrical portion 16 provided with a central portion protruding toward one surface side, an end surface portion 17 continuously provided outside the inner cylindrical portion 16, and an end surface portion thereof. It is provided with an outer cylindrical portion 18 which is continuous with the inner cylindrical portion 16 and is concentric with the inner cylindrical portion 16. On the outer peripheral surface of the inner cylindrical portion 16, there is provided an annular seal ridge 20 which is in pressure contact with the inner peripheral surface of the mouth member 12 for sealing. In addition, the inner peripheral surface of the outer tubular portion 18 is engaged with the outer peripheral edge of the mouth member 12 and has an annular retaining projection for preventing the stopper member from coming off.
21 are provided.

Reference numeral 22 is a knob for attaching and detaching the cap 13, and 23 is a rib for reinforcing the knob 23.

 Next, the operation will be described.

When freezing and storing the milk that has been milked using a breast pump or the like, first, hold the bag main body 11 containing the milk and raise the liquid level of the milk to the lower end of the mouth member 12, and then cap it.
The inner cylindrical portion 16 of 13 is inserted into the hole 12a of the mouth member 12, and the end surface portion 17 of the cap 13 is pressed. As a result, the cap 13 is capped on the mouth member 12.

In this case, the seal ridge 20 provided on the outer peripheral surface of the inner tubular portion 16 is pressed against the inner peripheral surface of the mouth member 12, and the retaining ridge 21 provided on the inner peripheral surface of the outer tubular portion 18 is provided on the mouth member 12. Is engaged with the outer peripheral edge of
Since the mouth member 12 is held so as to be sandwiched by the inner and outer cylindrical portions 16 and 18, the cap 13 is secured while ensuring the sealing performance.
It is possible to reliably prevent the slip-out.

In this way, when the air-bleeded and frozen capped mother's milk frozen storage bag B is placed in the freezer compartment of the refrigerator and laid sideways and frozen, the hole 12a of the cylindrical mouth member 12 becomes the inner cylinder portion of the cap 13. Since it is blocked by 16, the size of the ice (the cross hatched portion in FIG. 4) formed near the mouth member 12 is small.

When thawing the frozen breast milk, for example, the thawing container 7 as shown in FIG. 6 is used as described above. That is, the milk injected into the inner tank 9 is stored in the breast milk frozen storage bag B.
The milk-frozen storage bag B is warmed with the water in the inner tank 9 that has been warmed with hot water of about 90 ° C. poured into the outer tank 10, and the frozen milk in the bag body 11 is gradually thawed. And 40 of melted breast milk
Warm up to about ℃ and feed the baby.

As described above, by gradually thawing the frozen milk, it is possible to prevent the destruction and deterioration of the milk components due to heat. Moreover, since the mass of breast milk produced in the vicinity of the mouth member 12 is not so large, the whole frozen breast milk can be thawed relatively quickly even with lukewarm water.
Therefore, it is possible to quickly respond to the infant's desire to feed.

[Effects of the Invention] As described above, the present invention is configured as described above, so that it can be thawed quickly without destroying or damaging the components or nutrients of breast milk, and when necessary,
It is possible to provide an effect of providing a frozen milk storage bag cap capable of rapidly thawing the frozen stored milk and feeding the baby.
