Description

Bottle {NURSING BOTTLE}

The present invention relates to a feeding bottle, and more particularly, to a feeding bottle that can easily intake liquid and minimize intake of air by a venting circuit to improve safety and reliability.

Bottles and beverage containers for users to eat milk, drinks, etc. have been developed in various forms and structures. As an example of a baby bottle, a baby bottle of Patent Registration No. 130746 is connected to a baby bottle having an inlet for the storage of liquid, an adapter fitted to the bottle's inlet, a nipple adhered to the upper surface of the adapter, and a baby bottle. Consists of a collar to bind the nipples.

In the baby bottle of Patent No. 130746 having such a configuration, when the infant sucks the nipple, the liquid flows out of the bottle through the hole of the nipple. However, when the bottle is upside down or shakes, there is a problem that the liquid leaks through the gap between the nipple hole and the bottle and the collar. In addition, when the infant inhales the liquid, air in the bottle is leaked together with the liquid, and the internal pressure of the bottle decreases, so that the liquid does not flow smoothly. Concerns are very high. Therefore, it is very difficult to use a baby bottle with a weak suction force alone, which is accompanied by a cumbersome and inconvenient problem in that a parent shakes or presses the bottle to assist in the outflow of the liquid.

On the other hand, in order to facilitate the inhalation of infants in the bottle, the infant feeding nipple of Korean Utility Model No. 206846 is introduced into the bottle through the air hole formed in the gap between the bottle and the lid and the edge of the nipple. Techniques for smoothly maintaining outflow are disclosed. However, this technique has a problem that the infant directly sucks the air introduced into the bottle through the hole of the nipple. When infants inhale air, it causes stomach pain or vomiting due to swelling of the intestine, which is accompanied by an uncomfortable problem that must be trimmed after feeding.

As an example of a beverage container, the lid assembly for a beverage container of Korea Patent Publication No. 2001-40475 has a spout having an outlet as a liquid discharge means for outflow of liquid on a lid of a container, and has a spout adjacent to the spout. The lid has an air hole communicating with the container. The flexible diaphragm head and lip are configured to open the spout's outlet and the lid's air holes only when the user inhales the spout.

The lid assembly for a beverage container of Korean Patent Publication No. 2001-40475 has an air hole that is closed by a lip of a diaphragm when a user inhales a spout, and the outside air is introduced into the container, thereby preventing the leakage of liquid. It has the advantage of keeping it smooth. However, this technique is that when the container containing the liquid is upside down or falls, the diaphragm under pressure of the fluid is deformed, and the lip is spaced from the air hole of the lid by the deformation of the diaphragm, so that through the air hole of the lid There is a problem that a large amount of liquid leaks. Leaking liquids entail a very cumbersome and uncomfortable problem of asking a user to inhale a drink or contaminating the container.

The present invention has been made to solve the various problems of the prior art as described above, the object of the present invention is to provide a baby bottle that can easily prevent the leakage of liquid while the intake of the liquid by the ventilation circuit is easy and smooth. It is.

Another object of the present invention is to provide a bottle capable of ingesting an appropriate amount of liquid in accordance with the suction power of the infant by controlling to supply an appropriate amount of air into the bottle in proportion to the amount of the liquid ingested by the infant.

Another object of the present invention to provide a baby bottle that can improve the safety and reliability by minimizing the amount of air sucked by the infant.

A feature of the present invention for achieving such objects is a bottle having an inlet at the bottleneck for storage of liquids; A first channel and an air inlet pipe are formed at each of the flange and bottom center of the cup having recesses coupled to close the inlet of the bottle to introduce air into the bottle.

Now, the operation of the bottle according to the present invention having such a configuration will be described.

1, 2 and 3, first look at the assembly of the bottle according to the present invention, through the inlet 11 of the bottle 10, injecting a liquid, such as milk, drink in an appropriate amount, then the bottle ( The cup 21 of the air supplier 20 is coupled to the inlet 11 of 10. The temperature sensor 28 attached to the air inlet pipe 26 of the air supply 20 is changed from purple to pink when the temperature of the liquid is 36 to 38 ° C. or higher, and the bottle starts to change from pink to purple. Milk powder is fed to hot water stored in (10) to maintain the most appropriate temperature.

Next, the valve 30 and the disk 40 are sequentially mounted in the recess 23 of the cup 21. The tubes 45a, 45b of the disk 40 couple to the first liquid holes 27 of the air supply 20 through the second liquid holes 38 of the valve 30. At this time, when the first vent hole 32 of the valve 30 and the fourth vent hole 41 of the disk 40 are aligned so as to communicate with each other, the first vent hole 32 of the valve 30 is arranged in the opposite direction to the first vent hole 32 of the valve 30. The three vent holes 37 are positioned so that a long distance is formed between the first vent holes 32 and the third vent holes 37. The other three first vent holes 32a to 32c of the valve 30 are closed against the lower surface of the disk 40.

One of the first vent holes 32, 32a-32c of the valve 30, depending on where the tubes 45a, 45b of the disk 40 are coupled to the second liquid apertures 38 of the valve 30. Is aligned with and communicates with the fourth vent hole 41 of the disk 40. If the first vent hole 32b of the other three first vent holes 32a to 32c is aligned with and communicated with the fourth vent hole 41 of the disk 40, the first vent holes 32, 32a, 32c are closed against the lower surface of the disk 40. Similarly, the first vent hole 32a or the first vent hole 32c of the other three first vent holes 32a to 32c can communicate with the fourth vent hole 41 of the disk 40. . Therefore, regardless of the coupling position of the second liquid holes 38 and the tubes 45a and 45b of the disk 40, one of the four first vent holes 32, 32a to 32c is the fourth vent hole ( 41 is always in communication with each other to enable the flow of air, so that the first venting hole 32 of the valve 30 and the fourth venting hole 41 of the disk 40 must be assembled so as to prevent misalignment. It is possible to eliminate, and by incorrectly assembling the valve 30 and the disk 40 can prevent the flow of air is cut off.

Finally, after mounting the valve 30 and the disk 40 to the cup 21 of the air supply 20, the bottle in the state where the upper part of the nipple 50 is projected to the hole 63 of the cap 60 When the female screw 61 of the cap 60 is fastened to the male screw 13 of (10), the flange 51 of the nipple 50 comes into close contact with the upper surface of the disk 40 so that airtight assembly is completed. do. At this time, a second vent passage 62 is formed between the male screw 13 of the bottle 10 and the female screw 61 of the cap 60 by the disconnected portion.

Referring to FIG. 6, when the bottle 10 is tilted such that the liquid in the bottle 10 reaches the inlet 11, the liquid is the first liquid of the air supply 20 as indicated by the arrow "A" in FIG. 6. Through the holes 27, the second liquid holes 38 of the valve 30 and the third liquid holes 42 of the disk 40, the inner space of the nipple 50 is filled, and the infant is nipple 50. ), The liquid flows out through the hole 63 of the nipple 50.

Referring to FIGS. 3, 4 and 7, air is drawn between the venting circuit, that is, between the male screw 13 of the bottle 10 and the female screw 61 of the cap 60, as indicated by arrow “B” of FIG. 7. The first channel 24 of the air supply 20, the second channel 43 of the disk 40, and the first ventilation of the valve 30 are introduced through the second ventilation passage 62 formed in the valve. The bottle 10 is sequentially passed through the hole 32, the first vent passage 35, the third vent hole 37, the second vent hole 34, and the air introduction pipe 26 of the air supply 20. Supplied into the stomach.

On the other hand, when the bottle 10 is tilted for the intake of the liquid, the empty space 14 of the bottle 10 close to the bottom becomes a vacuum as shown in FIGS. 6 and 7 by the flow of the liquid, and the valve The diaphragm 33 is elastically deformed by the air pressure acting on the diaphragm 33 of the valve 30 while being spaced apart from the plug 46 of the disk 40, as indicated by arrow "C" in FIG. 7. Allows the introduction of air through the second vent hole 34. Air introduced through the second vent hole 34 of the valve 30 is supplied to the empty space 14 of the bottle 10 through the air introduction pipe 26 of the air supply 20. At the same time as the outflow of the liquid, the empty space 14 is supplied with air through the ventilation circuit in proportion to the outflow amount of the liquid.

As the air is filled in the empty space 14 of the bottle 10 as described above, the vacuum of the empty space 14 is released, so that the internal pressure and the atmospheric pressure of the bottle 10 are balanced, so that the infant smoothly drinks the liquid with little force. It can be easily consumed by spilling. In addition, the infant may not directly suck the air supplied into the bottle 10 by supplying air to the empty space 14 adjacent to the bottom of the bottle 10, it is possible to minimize the amount of air intake. . As a result, the feeding bottle of the present invention can effectively prevent otitis media, stomach ache, and vomiting that infants tend to develop.

In addition, when the internal pressure and the atmospheric pressure of the bottle 10 are in equilibrium, the diaphragm 33 of the valve 30 is restored and closely adhered to the plug 46 of the disk 40, so that the second vent hole of the valve 30 is close. Close 34. The amount of air is proportional to the amount of liquid flowing into the bottle 10 by opening or closing the second vent hole 34 by the diaphragm 33 of the valve 30 operating according to the internal pressure of the bottle 10. Can be controlled appropriately.

Referring again to FIG. 6, when the bottle 10 in which the liquid is stored is upside down or falls, the diaphragm 33 of the valve 30 which is subjected to the pressure of the liquid concentrated at the inlet 11 of the bottle 10. ) Closes the second vent hole 34 of the valve 30 while being in close contact with the plug 46 of the disk 40 by elastic deformation.

Referring to FIG. 7, when a small amount of liquid leaks through the second vent hole 34 while the diaphragm 33 of the valve 30 is spaced apart from the plug 46 of the disk 40, the leaked liquid may be The third vent hole 37 of the 30, the first vent hole 35, the first vent hole 32, the fourth vent hole 41 of the disk 40, the second channel 43, the third After passing through the channel 44 and the first channel 24 of the air supply 20 sequentially, and finally, the second ventilation passage formed between the bottleneck 12 of the bottle 10 and the cap 60 ( Through 62) out of the bottle (10).

As such, the liquid leaking in the opposite direction to the ventilation circuit for introducing the air has to go through a long distance, thereby minimizing the leakage of the liquid. In detail, the liquid passing through the third vent hole 37 of the valve 30 is formed to form a long distance along the circumferential direction between the third vent hole 37 and the first vent hole 31. It is delayed to reach the first vent hole 31 while flowing along the first vent passage 35, and the liquid is stored in the first vent passage 35, thereby effectively preventing leakage of the liquid through the vent circuit. In particular, the leakage of the liquid through the ventilation circuit is blocked by the pressure of the liquid filled in the ventilation circuit. The liquid that has been filled in the ventilating circuit is re-introduced into the bottle 10 with air in accordance with the suction of the infant and recovered.

On the other hand, when another 1st ventilation hole 32b formed in the position opposite to the 1st ventilation hole 32 of the valve 30 approaches the 3rd ventilation hole 37, the 1st ventilation hole 32b ) And the third vent hole 37 form a near-distance path, but as described above, the flow of the liquid is blocked by the pressure of the liquid filled in the vent circuit, thereby effectively preventing the leakage of the liquid. By near-coiling between the first vent hole 32b and the third vent hole 37, it is possible to speed up the introduction rate of air from a long distance.
