Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a tubular cap for a baby bottle. The tubular cap for baby bottles of the present invention is a tubular cap that is attached to the inside of the mouth of a baby bottle and has a hollow inside to fix the nipple together with the cap of the baby bottle. Between the outer wall and the inner wall of the tubular cap of the present invention, there is a deep ring-shaped recess that extends downward to the bottom, and the bottom portion of the recess has a few downwardly open air openings. The entrances are lined up in a ring. The air outside the baby bottle, introduced from the air inlet valve at the bottom of the nipple, is led through the recess to the air inlet, which is slightly further away from the mouth of the bottle. Then, by automatically selecting a low-pressure point and preferentially supplementing air into the bottle from the inlet of the air closest to the air originally stored in the bottle, Avoid areas where some residual fluid is sucked out and prevent air from entering the abdomen thoroughly.

2. Description of the Related Art Baby bottles allow infants to drink milk,
It is an essential feeding device when giving fluids such as juice and water. The nipple of the baby bottle is attached to the baby bottle with the cap, and the baby bottle is sucked by being contained in the mouth of the baby and feeding the liquid in the bottle. However, when sucking the nipple of a baby bottle into an infant, the pressure in the bottle is unbalanced unless the air outside the bottle is properly taken in, and the liquid in the bottle cannot be sucked well. Therefore, a small air entrance hole is always opened below the portion of the baby bottle including the mouth of the nipple. A cap is attached to the upper part of the baby bottle, and while the liquid is sucked out in the process of sucking the nipple, at the same time, a proper amount of outside air is automatically taken in. The presence of the air entry hole adjusts the pressure balance.

However, when sucking the nipple, a liquid discharge area having a large suction force is naturally formed in the passage of the liquid inside. Therefore, when the air outside the bottle is introduced by the air inlet holes around the passage of the liquid, a part of the air around the passage of the liquid is naturally sucked out together with the liquid sucked out of the bottle. The infant often enters the abdomen of the baby, becomes bloated, becomes uncomfortable, and sometimes cry because of pain.

[0004] In order to solve this problem, in the previous patent, several improvements were proposed in order to overcome the drawback that the air inlet valve of the nipple causes the problem of the abdomen of the infant. US Patent No: 5678710: NIPPLE
The FOR NURSING BOTTLES installs the extension passage of the protruding extension tube 2 (see FIGS. 1 and 2) so that the air AIR outside the bottle is moved to the initial position in the feeding bottle P, that is, the liquid inside the nipple N. The approach is to be made at a position away from the lower part of the path N1. This is liquid L
Although the air AIR does not cause the phenomenon that the air AIR enters the abdomen of the baby and becomes bloated when the air is sucked and discharged from the nipple N, the tilted state of the baby bottle as shown in FIGS. Seen from above, the "unidirectional" protruding extension tube 2
Is in the bottom position (as in FIG. 2) and the liquid L in the bottle is
When there is a large amount of residual amount, the pressure is relatively large, and there is a basic drawback that the liquid does not go out smoothly. Further, the air AIR, which has a smaller mass than the liquid L, inevitably rises vertically. On the contrary, when it is close to the area where the remaining liquid inside the passage N1 behind the liquid is discharged, there is a possibility that it will be dissolved in the remaining liquid L and sucked together.

Further, in order to improve this, when the protruding extension tube 2 is moved upward (see FIG. 3), the remaining amount of the liquid L in the bottle becomes small, the pressure becomes small, and the liquid The output will improve. Then, when the air AIR rises in the vertical direction, it quickly dissolves in the air originally retained in the bottle near the upper surface of the remaining liquid L. However, also due to the drawback that the projecting extension tube 2 is "unidirectional", it will face up correctly (see FIG. 3) and continue to be used, which is practically difficult and inconvenient.

In order to prevent the above-mentioned air AIR outside the bottle from dissolving in the remaining liquid L, a new baby bottle has been developed. Between the nipple cap (the nipple attached to the middle stage) and the mouth of the baby bottle, a pair of separate air admission tubes was added.
This is a design that directs the air outside the bottle to the position of the bottom of the baby bottle (eg US Patent No. 577907).

structure). This structure was certainly as good as expected. But it is independent and must be installed separately and assembled with several parts. The intricate structure of the isolated air inlet tube is
In addition to being inconvenient to assemble and use, the dedicated structure does not work well with the standard baby bottles and nipples, and the manufacturing cost is reflected in the price, which obviously increases the burden on consumers and is not practical. Absent. In particular, it is difficult to completely seal the inside of the bottle, the nipple, and the process of attaching them between the nipple caps, which combine several parts in layers.
Air leaks occur. This is inconvenient to use, and the frequency of failure increases.

[0007]

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a tubular cap for a baby bottle which prevents air from entering the abdomen of an infant.

[0008]

The tubular cap for a baby bottle of the present invention is attached to the upper part of a baby bottle, and a slightly elevated ring-shaped neck portion in the hollow portion of the baby bottle is attached to the mouth of the baby bottle. It is a hollow tubular cap that is inserted inside and holds the nipple together with the cap of the baby bottle.
Between the outer wall and the inner wall of the tubular cap of the present invention is a deep ring-shaped recess extending downwardly to the bottom. At the bottom of the depression, there are several downward air inlets arranged in a ring. The air outside the baby bottle, which is introduced from the air inlet valve at the bottom of the nipple, is guided through the downwardly extending recess to the air inlet, which is a little far from the mouth of the bottle. Then, it automatically replenishes air preferentially from the low-pressure air inlet, avoiding the area in the baby bottle that discharges the remaining liquid and thoroughly prevents air from entering the abdomen. There is a feature of preventing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Please refer to FIG. 4, FIG. 5 and FIG. The tubular cap for baby bottles according to the first embodiment of the present invention is a tubular cap 3 having a hollow inside the mouth PA of the conventional baby bottle P.
It is a structure that only attaches. Its tubular cap 3
Has a stop portion 31 on the outer periphery of the uppermost portion,
It is attached so as to straddle above the mouth PA. Then, the hollow portion 3A inside the tubular cap 3
The inner wall of the has a ring-shaped neck portion 32 having a slightly raised upper portion so as to fit into the mouth of the lower portion of the nipple. Then, the nipple N is pinched and fixed together with the nipple cap P1.

The tubular cap 3 is provided between the outer wall and the inner wall,
There is a deep ring-shaped recess 33 extending downward to the bottom. On the bottom surface of the recess 33, several air inlets 331 opened downward are arranged in a ring shape. Please refer to FIG. 6 and FIG. Due to the presence of the deep ring-shaped indentation 33, the nipple N above the indentation 33 has a ring type in which the outside air AIR introduced from the air inlet valve N2 at the bottom of the nipple N extends downward. It is guided toward the hollow 33 and further to the air inlet 331 away from the position of the mouth of the bottle. Then, it is discharged into the bottle. The length of the tubular cap 3 is at least equal to or longer than the length of the uppermost spiral portion PB of the baby bottle P. Therefore, the air AIR introduced into the baby bottle P from the air inlet 331 leaves the main liquid discharge area below the passage N1 of the liquid inside the nipple N, and the introduced air A
Prevent the IR from being sucked in with the liquid L in the bottle.

Referring to FIG. When the general baby bottle P is in an inclined state, the distribution distribution of the liquid L in the bottle forms a zone with a slightly higher pressure below the liquid surface and a zone with a slightly lower pressure above it. The air inlets 331 arranged in several rings are
A condition for receiving pressure at different mouth positions of high and low (the distribution state of pressure magnitude is indicated by arrows of different magnitude in FIG. 7) is formed. Therefore, the air AIR outside the bottle has a characteristic that it is discharged into the recess 33 in an arbitrary direction, rises due to its light mass, and flows to a low-pressure portion. That is, the ring-shaped passage of the recess 33 is automatically headed to the lowest point. This also means that the bottle is preferentially replenished from the position of the air inlet 331 located closest to the upper side of the liquid surface. Further, the air AIR discharged from the air inlet 331A located at the upper position is sucked together with the liquid L in the bottle to avoid the main liquid discharge area of the passage N1 inside the nipple N, and the abdomen is stretched. In addition to preventing such a situation, a small amount of liquid L passes through a very short distance after the air AIR is introduced, and even if it momentarily rises, it fuses with the air originally retained in the baby bottle P. Since the pressure in the bottle is balanced, an infant can smoothly drink the liquid in the baby bottle.

Please refer to FIG. 8, FIG. 9 and FIG. In the tubular cap for a baby bottle according to the second embodiment of the present invention, the inward position of the air AIR which is extended to the rear side is formed with the recess 3 in order to avoid the main liquid discharge area below the passage N1 of the liquid inside the nipple N.
A protrusion-shaped air-core column 331A extending to the outside of the ring-shaped air inlet 331 on the bottom surface of No. 3 is attached. Further, the air-core column 331A is an air-core extension tube S of an appropriate length.
It is also possible to attach to. By doing so, the position of the end outlet of the air AIR can be extended further rearward. Alternatively, or additionally, the air core extension tube S can be added to extend the air entry position to the bottom of the baby bottle P, so that the air AIR entering from the outside of the bottle can be extended.
It certainly prevents the situation where the is sucked in with the liquid in the bottle. Therefore, it is possible to thoroughly eliminate the situation in which the abdomen is stretched by sucking air when the baby uses the baby bottle.

Please refer to FIG. 8, FIG. 9 and FIG. The tubular cap for baby bottles according to the second embodiment of the present invention can be combined with an automatic suction tube unit. Its structure is
A ring-shaped fitting portion 321 is provided at the upper end of the hollow portion inside the ring-shaped neck portion 32 in the hollow tubular cap 3, and the fitting portion 321 allows the extension type absorbent soft tube to extend downward. 41 and the suction head 4 at the end
The movable bottom piece 4 having 2 and 2 is fitted into the upper part and fixed. The liquid absorbing soft tube 41 and the liquid absorbing head 42 at the end pass downward from the hollow portion 3A and enter the inside of the baby bottle P. This completes the air entry assist device. this is,
The baby bottle unit can be arranged in any orientation and operates similarly to the automatic suction tube unit. This opens up a wide range of choices for consumers, making replacement easy, convenient and economical.

[0014]

According to the tubular cap for baby bottles of the present invention, a tubular cap having a hollow inside is attached to the inside of the mouth of the baby bottle, and the nipple is fixed together with the cap of the baby bottle.
The air outside the baby bottle is taken in, and automatically the low pressure part, that is, the place near the upper air inlet of the air originally stored in the baby bottle is selected and replenished preferentially, and the inside of the nipple It has the effect of surely avoiding the main liquid discharge area of the liquid passage in. The introduced air outside the bottle is prevented from being sucked together with the liquid in the bottle, so that the baby can smoothly suck the liquid. Therefore, by sucking in air, it is possible to avoid the problem that the baby has a tight abdomen and suffers from difficulty. INDUSTRIAL APPLICABILITY The tubular cap for baby bottles of the present invention has features that it is simple and convenient, has high applicability, is inexpensive, and is easy to wash.

The tubular cap for baby bottles of the present invention is
An air-core column projects outside the ring-shaped air inlets on the bottom of the depression. This connects to one end of an air-core extension tube of unlimited length. Therefore, at the position of the outlet at the end where the air enters, extending backward to the position of the bottom of the baby bottle simply, conveniently, and surely,
Air entering from outside the bottle is never sucked out again with the liquid inside the bottle. Therefore, the defect that the abdomen is stretched due to the sucking of air by the infant is more reliably prevented.

Furthermore, the tubular cap for baby bottles of the present invention has an extended liquid absorbing soft tube at the bottom and a liquid absorbing head at the end in the inner hollow portion of the ring-shaped neck portion in the hollow tubular cap. It is designed to attach a movable bottom piece, and to fix it by fitting the upper part. Then, the liquid absorbing soft tube and the liquid absorbing head at the end pass downward from the mouth portion of the hollow tube and enter the inside of the baby bottle.
In this way, an ideal feeding effect can be expected by the vertical array type having the same action as the automatic suction tube unit. Therefore, the tubular cap for baby bottles of the present invention is convenient for consumers to use and easy to replace. And the economic effect is also high.
