Background technique

Existing feeding bottles generally contain two states:

A kind of feeding bottle for adults to feed infants and young children, generally including the bottle body, nipple, screw cap, dust cover, etc. During the feeding process for adults and infants, the feeding bottle must maintain a certain inclination and the nipple must be downward. Only the milk can fill the nipple, and infants and young children can drink the milk smoothly (as shown in Figure 1-1); if the bottle is flat or reversely inclined, and the nipple is up, there will be no nipple If milk is present, infants and young children will not be able to suck up milk. They can only breathe the air in the bottle, and they will drink too much air into their stomachs, forming flatulence, and then spit milk due to flatulence, which is very unfavorable for infants Health (as shown in Figure 1-2/1-3).

The other is a baby bottle for infants and young children to grasp and suck up milk by themselves, generally including a bottle body, a pacifier, a screw cap, a silicone straw with a gravity ball, a straw blade and other parts. This kind of milk bottle directly connects the inside of the nipple and the bottle through a silicone straw Inside the body. When infants and children use it, because there is air in the nipple and the straw, infants and young children must drink the air in the nipple and the silicone straw before drinking the first sip before the milk can be sucked into the straw and under the effect of atmospheric pressure. In the nipple, so that the infant can drink milk; when the infant's mouth leaves the nipple, the milk that originally existed in the nipple will flow back to the bottle through the silicone straw due to its own gravity. In the bottle body, so, when the infant drinks milk again, the air in the nipple and the straw will be repeatedly consumed, and then the milk can be drunk again; in this way, the infant will drink too much air into the stomach, forming Flatulence, and the phenomenon of spitting milk due to the presence of flatulence, is very detrimental to the health of infants and young children (as shown in Figure 2).

The teat 2 is inserted into the screw cap 9 and is installed on one end of the bottle body 1 through the screw cap 9. The teat 2 has a second chamber 201 whose opening is opposite to the opening of the first chamber 101.

The partition 3 is provided between the bottle body 1 and the nipple 2 to partition the first chamber 101 and the second chamber 201. The partition 3 is provided with a through hole 301 that communicates the first chamber 101 and the second chamber 201.

The valve piece 4 is provided on the side of the separator 3 close to the bottle body 1, and the valve piece edge 401 is attached to the side of the through hole 301 to seal the through hole 301; One end extends into the first chamber 101, and the other end extends into the second chamber 201; the connecting pipe 402 extends into the second chamber 201 of the teat 2 at one end is provided with a connecting pipe check valve 403, the connecting pipe check valve The flow direction controlled by 403 is that the liquid flows from the first chamber 101 to the second chamber 201, and the connecting tube 402 extends into one end of the first chamber 101 for connecting the silicone straw 8 with a gravity ball.

The opening and closing button 5 is provided on the nipple 2 and corresponds to the through hole 301, and is used to push the edge 401 of the valve piece 4 to open the through hole 301.

When in use, first turn the feeding bottle 1 so that the nipple 2 faces down and the bottle body 1 faces upwards, then press the opening and closing button 5, and the opening and closing button 5 moves toward the valve sheet 4 and pushes the edge 401 on the valve sheet 4 to open the partition sheet 3 Through the through hole 301, the milk flows from the first chamber 101 into the second chamber 201 of the nipple 2 through the through hole 301 due to the force of gravity, until the second chamber 201 is filled up, the button 5 is opened and closed, and the valve piece 4 The edge 401 is reset to close the through hole 301, and then the baby bottle is given to the infant to drink milk. Since the second chamber 201 is already filled with milk, the infant and the child drink milk at the first sip instead of air . After that, as the milk in the second chamber 201 of the teat 2 is continuously sucked away, due to the pressure difference, the milk in the first chamber 101 of the bottle body 1 passes through the silicone straw 8 with gravity ball and the valve piece 4 The connecting pipe 402 and flushing the connecting pipe check valve 403 to replenish the second chamber 201 of the teat 2 so that the second chamber 201 is always filled with milk. Moreover, in the gap between drinking milk, when the mouth of the infant leaves the nipple 2, because the edge 401 of the valve piece 4 blocks the through hole 301 of the separator 3, the milk in the second chamber 201 of the nipple 2 cannot pass through the through hole 301 Flow back to the first chamber 101, and the valve piece 4 is provided with a connecting pipe check valve 403, milk cannot flow from the connecting pipe 402 of the valve piece 4 back to the first chamber 101 of the feeding bottle 1, therefore, when the infant drinks milk again The milk you drink is always until you have finished drinking the milk in the bottle, and you will never drink air, thus avoiding the occurrence of flatulence caused by too much air into the stomach of infants and young children. problem.

The partition 3 includes a sheet-shaped base 31, and the through hole 301 penetrates the base 31. The valve piece 4 can seal the through hole 301 by abutting on the side of the partition 3, and the structure is very simple, which is convenient for disassembly, installation and cleaning. Further, the valve 4 is made of silicone material or other soft materials that can contact with food. Silicone or other soft materials that can be in contact with food have a certain elasticity and can bear a certain weight. The opening and closing button 5 applies a certain force to the edge 401 of the valve sheet 4 to push the edge 401 to deform, thereby opening the through hole 301 If the applied force is removed, the edge 401 of the valve piece 4 will automatically reset, closing the through hole 301.
