Description

Vacuum structure of the milk bottle for baby using vacuum valve body}

The present invention relates to a vacuum structure of a baby bottle using a vacuum valve body, and more specifically, to prevent unnecessary waste of nutrient-rich breast milk and milk powder by keeping the formula or breast milk remaining inside the bottle after feeding for a certain time. It is to.

In the case of not breastfeeding infants directly, most of the infants are fed with liquid milk or breast milk using the normal bottle (1) shown in FIG. 1, and the remaining mother's milk and milk during lactation are wasteful. It is common to leave it inside the bottle for a while and re-feed.

However, breast milk and powdered milk are gradually oxidized and decayed over time within the bottle.

Therefore, some bottles of breast milk or powdered milk are kept refrigerated, but there is a hassle of having to heat them to lukewarm temperature when re-feeding. Of course, there is a risk of harm, as well as discarded the remaining breast milk and milk powder would cause unnecessary waste.

Therefore, the present invention has been devised to solve the conventional problems, the purpose of which is to keep the breast milk and powdered milk remaining after feeding in a fresh state for a certain time at room temperature inside the bottle, reducing the waste of breast milk and milk powder and refrigerated This is to prevent the hassle that has to be lukewarm when re-feeding after storage. It operates according to the pumping operation of the pumping port, and removes the air inside the bottle to maintain the vacuum state for a longer time. It is intended to keep fresh milk and milk powder in the baby bottle at room temperature.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

2 is a view illustrating an operation example of the present invention,

Fig. 2A is an operation diagram of intake and exhaust of air inside the bottle by the vacuum valve body and the pumping port to the outside.

Fig. 2B shows an operation diagram for maintaining the vacuum state inside the bottle by the valve of the vacuum valve body, respectively.

Reference numeral A denotes a vacuum valve body, and the vacuum valve body A is formed with a concave inlet portion 12 for injecting and installing a soft sealing member 11 configured in a ring shape, and a valve to be described below is fitted and fastened. The cover 10 formed with the boss 13 having a fitting hole 14 to be formed in the center.

Here, the boss 13 is to protrude from the center of the cover to the upper, lower side, in particular at least four radially vented holes (13a) to the lower portion to form a constant equal intervals.

Then, the fitting is fastened to the inside of the boss of the cover to configure the valve 20 to selectively seal the fitting hole of the boss as the fluid passage in accordance with the operation of the pumping port (30).

The valve of the illustrated embodiment is preferably composed of a material such as silicone having excellent flexibility and sealing properties, such a valve is the recessed groove 21, which is a fluid space for lowering faster than when the extremely low pressure is formed inside the bottle. It is formed on the inside, it is to form a catching piece (22) to prevent the valve that rises during the pumping port pumping operation to the lower outer peripheral surface is caught by the lower end of the cover boss.

And it forms the sealing piece 23 which seals the boss upper opening part of the cover which is a substantially fluid flow path while raising and lowering to the outer peripheral surface of a valve upper side.

Here, the indentation groove of the valve is formed to a length that does not pass through the sealing piece at the point of about 중 of the total length (L) of the valve, even when deformation occurs in the indentation groove when extremely low pressure is generated inside the bottle. The sealing piece of the valve sealing the boss opening of the cover must not be deformed.

Further, the boss upper end portion of the cover is chamfered 13b inward, and the tapered chamfered portion 24 is formed in the form of a light beam narrower on the valve body below the sealing piece of the valve so as to contact the chamfered portion as a face. Ensure a tight seal.

Figure 4 is a longitudinal cross-sectional view for explaining another embodiment of the present invention, according to this view, by extending the outer (15) of the cover to form a screw thread (15a) on the inner surface of the cover (10) ) Is screwed in so that the cover does not shake or move when the pumping port is in operation.

When explaining the operation of the present invention made in the configuration as described above in detail.

That is, when breast milk and powdered milk remaining in the feeding bottle (1) are not refrigerated and stored in a fresh state at room temperature for a certain period of time, after separating the holder from which the nipple is fastened from the feeding bottle, the vacuum valve body which is a component of the present invention. Place (A) in the opening at the top of the bottle. At this time, the sealing member 11 placed on the lower concave portion 12 of the cover constituting the vacuum valve body is positioned in contact with the upper end of the bottle.

Then, after the pumping port 30 having a conventional structure is located outside the boss 13 in the center of the cover and the user performs the pumping operation of the pumping port fastening to the boss fitting hole 14 of the cover according to the pumping operation The valve 20 is repeatedly raised and lowered to gradually inhale and evacuate the fluid (air) present in the bottle to remove the air causing oxidation and corruption by contacting breast milk or milk powder, thereby maintaining the inside of the bottle in a vacuum state. The milk and milk powder remaining in a fresh state that does not rot for a time will be stored, and this process will be described in more detail as follows.

For example, when the user repeatedly performs the pumping operation of the pumping port as shown in FIG. 2A, the valve 20 installed in the boss fitting hole 14 of the cover is raised to raise the sealing piece 23 formed on the outer peripheral surface of the boss. The fluid inside the bottle is exhausted from the upper opening through the vent hole 13a and the fitting hole 14 at the lower end of the boss. At this time, the rising valve is caught on the lower end of the engaging piece 22 formed integrally on the outer peripheral surface of the boss is no longer the valve does not rise, and also does not go out.

Subsequently, the valve 20 is lowered as shown in FIG. 2B due to the pressure generated inside the bottle, and the upper end of the open boss is tightly sealed as a side of the valve, where the valve is positioned below the valve. Thus, the chamfer 24 of the upper and lower strait form formed integrally with the valve body is in close contact with the chamfer 13b formed on the inner circumferential surface of the boss upper end as a surface to obtain a perfect sealing force.

In addition, when the valve 20 is lowered according to the pressure generated inside the bottle, the valve can be lowered more quickly and accurately by the inlet groove 21 formed inside the valve, the inlet groove is the valve length It is formed only to the point of about 중 of the length (ℓ), so if the valve body of the concave groove formed part is deformed when the pressure is extremely low, the sealing piece formed on the upper part of the valve which performs a substantially sealing role It is designed so as not to be deformed so that the sealing force of the sealing piece 23 does not affect anything.

As the lifting and lowering operation of the valve is repeatedly performed several times in accordance with the pumping operation of the pumping port, gradually the inside of the bottle maintains a very low vacuum state, and the milk and powdered milk remaining inside the bottle in the vacuum state are decayed. It has little contact with the promoting air, so you can keep the milk you have left for a longer time.

On the other hand, as shown in Figure 4 by extending the lower portion of the cover 10 as necessary 15, and fixing the vacuum valve body to the upper end of the bottle using a screw thread (15a) formed on the inner surface, the pumping operation of the pumping port The vacuum valve body can eliminate the inconvenience of moving from the top of the bottle.

According to the above-mentioned proposal, according to the mutual connection operation of the vacuum valve body and the pumping port, the air inside the bottle, which promotes oxidation and decay, is rapidly sucked out to maintain the vacuum state. It can solve the problem of having to discard the breast milk or powdered milk of milk, or the inconvenience of having to lukewarm after storage. It is a new useful tool that can keep the remaining milk and milk powder at room temperature inside the bottle for a certain time. It is an idea.
