Description

Bottle Return System This application claims priority to Chinese Patent Application No. 200920001593.8, entitled "Bottle Return System," filed on January 19, 2009, the entire contents of which are incorporated herein by reference. Application. Technical field

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component for a baby bottle, and more particularly to a bottle return air system for returning the baby bottle to allow the baby to dynamically balance the internal and external pressure of the baby bottle when the baby is sucked. Background technique

Bottles are commonly used during the growth of infants. In the use of the bottle, when the baby sucks the milk powder solution through the nipple, as the solution in the bottle decreases, the air pressure in the bottle is less than the air pressure outside the bottle, and the vacuum inside the bottle occurs, and the baby is laborious. In the normal use of pacifiers, since the pressure difference between the inside and outside of the bottle is caused when the baby sucks the milk through the nipple, the air enters the bottle through the mouth, the return hole and the nipple, so that the air bubbles dissolved in the milk powder and the water form a flatulence, so that the baby sucks Inhalation of air from the milk causes paroxysmal intestinal fistula and abdominal pain, which can cause problems such as vomiting and separation.

At present, there is a return air system, which consists of two parts, a return air cover and an air guide tube. There are one or two return air holes on the return air cover, which can achieve some return air effects. However, there are two bad loopholes in the gas return system: a. One return air hole or two return air holes can only return air at the position of the return air hole, and the air return effect is affected; b. It is not easy to disinfect or clean the system stain, health. Summary of the invention

The object of the present invention is to provide a bottle returning system which has a simple structure, a good air return effect and is easy to clean in response to the above problems.

In order to achieve the above object, the present invention uses the following technical solutions:

A bottle returning system includes a return air cover and an air guiding pipe, and the return air cover includes:

An upper cover, the upper cover is provided with at least two milk outlet holes in a circumferential direction, and the edge of the milk outlet hole extends downward to form at least two first passages;

a cover, a milk inlet hole is formed at a position corresponding to the milk inlet hole at a periphery of the lower cover, and the edge of the milk inlet hole extends upward to form a second passage, and the second passage closely matches the first passage to form a milk a passage, an air flow passage is formed in an outer space of the milk outlet passage, and an outer circumferential portion of the lower cover extends upward to form an annular flange, and at least two air return openings are formed on the annular flange, and the lower side of the lower cover is downwardly a boss is protruded, and a vent hole is disposed at a center of the boss, and the vent hole is in communication with the air flow passage;

The air guiding tube is sleeved on the boss.

Preferably, the upper cover has three milk outlet holes, and is arcuate in shape and uniformly disposed in the circumferential direction.

Preferably, the number of the air return ports is three, and is disposed at a position corresponding to the air flow channel. Alternatively, an annular recess can be provided on the lower side of the lower cover for fitting into the bottle opening.

Alternatively, a cylinder may be provided at the center of the boss, and the vent hole is located at the center of the cylinder.

Alternatively, the boss includes a central cylinder and a ring wall surrounding the cylinder, the venting hole being located at a center of the cylinder, and the air guiding tube being sleeved outside the annular wall.

Preferably, the air guiding tube has a large diameter end and a small diameter end for being sleeved with the ring wall, and a slot is formed in the small diameter end.

Compared with the prior art, the bottle returning air system of the present invention forms a venting passage outside the milking passage and communicates with the outside through the air return port and the bottle spinner, and the return air can be returned to the bottom of the bottle along the venting passage and the air guiding tube. At the same time, avoiding the air dissolved in the water to form flatulence, which causes the baby to have problems such as vomiting and severing, and the air return port and the ventilating passage form a surrounding air return, and the return air is not restricted by the direction, and the air return effect is good; The gas cover is composed of a combination of an upper cover and a lower cover, and the two can be disassembled, which is convenient for cleaning and more sanitary.

The invention will be further described below in conjunction with the drawings and specific embodiments.

1 is a bottle returning system of the present invention, comprising a return air cap and an air guiding tube 30, the return air cover comprising: an upper cover 10, the upper cover is provided with three milking holes in the circumferential direction, and the milk is discharged. The hole shape is curved and uniformly disposed in the circumferential direction, and the edge of the milking hole extends downward to form at least two first passages 11.

The return air cover further includes a lower cover 20. Referring to FIG. 1 and FIG. 2, three milk inlet holes are provided at a position corresponding to the milk inlet hole at the periphery of the lower cover, and the edge of the milk feed hole extends upward to form a second passage. 21, the second passage 21 is closely matched with the first passage 11 to form a milk passage, and an air flow passage 22 is formed in an outer space of the milk passage, and an outer annular portion of the lower cover 20 extends upward to form an annular flange 23. Three air return ports 24 are formed in the flange 23, and the air return ports 24 are disposed at positions corresponding to the air flow passages 22. A boss 25 is protruded downwardly from the lower side of the lower cover 20, and a vent hole 26 is formed in the center of the boss 25, and the vent hole 26 communicates with the air flow passage 22. The air tube 10 is sleeved on the boss 25.

An annular recess 27 is provided on the lower side of the lower cover 20 for fitting with the bottle opening, so as to better seal the bottle mouth and prevent the milk from overflowing.

As shown in FIG. 1, a cylinder 28 may be disposed at the center of the boss 25, and the vent hole

26 is located at the center of the cylinder 28, which prevents the milk entering the airway 10 from entering the vent 26 when sucking, thereby affecting the return air. The boss 25 may also include a central cylinder 28 and a ring wall (not shown) surrounding the cylinder, the vent hole 26 is located at the center of the cylinder 28, and the air guiding tube 30 is sleeved in the ring Outside the wall.

The air guiding tube 30 has a large diameter end 31 and a small diameter end for being sleeved with the boss 25.

32. A slot 33 is formed in the small diameter end 32. When the thick diameter end 31 is sleeved outside the boss 25, a plenum is formed near the boss to avoid large pressure fluctuations in the bottle when the baby sucks more, and at the same time, a part of the bottle can be stored when the bottle is inverted. The milk of the airway tube 10 prevents the milk from entering the venting opening 26. The small diameter end 32 is used to guide the air, and the slot 33 is opened to ensure even the thin end 32 Touching the bottom of the bottle, the air can still be reliably introduced.

Figure 3 is an assembly view of the bottle. In Fig. 3, the upper cover 10, the lower cover 20 and the air guiding tube 30 are sequentially mounted together, and then placed in the bottle opening of the bottle, which is pressed by the bottle cap 60. When the baby sucks the milk, the milk flows out from the milking passage of the upper and lower lids through the nipple 50; and the air enters from the screw opening between the bottle cap 60 and the bottle 40, and flows through the air return port 24, the air flow passage 22, and the air duct 10 The bottom of the bottle of the bottle 40 ensures that the milk flows smoothly.

The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should be considered as the scope of protection of the present invention.
