Description

[Detailed description of the invention] [Field of industrial application] This invention allows the amount of sucking by an infant to be adjusted by controlling the amount of outside air introduced with a pressure regulating cap installed in the baby bottle. Concerning baby bottles.

[Conventional technology and its problems]

In general, in a nursing bottle that does not have an outside air introduction hole, when an infant continuously sucks the nipple, the inside of the bottle becomes under negative pressure, and the nipple eventually contracts and becomes unable to suck.

To deal with this, in recent years, products have been developed that use the collar of the nipple or a cap nut for attaching the nipple to provide an introduction hole for outside air, but these introduction holes are required to be extremely thin. Therefore, for the above-mentioned nipples made of soft materials such as latex, it is impossible to simultaneously mold them with a mold, and the holes are generally perforated with a punch.
Not only is it time-consuming to manufacture, but due to changes in conditions such as the elongation of the rubber and wear of the punch, it is difficult to consistently obtain uniform perforations, resulting in inconveniences such as the amount of milk sucked becomes unstable. It is.

In addition, by opening a cylindrical ventilation hole on one side of the baby bottle, and screwing a small lid with a ventilation hole on the side and a gasket on the inner bottom surface into the cylindrical ventilation hole, each of the above-mentioned "Baby bottle ventilation hole device" (Utility Model Application Publication No. 48-22687) in which the ventilation hole can be opened and closed freely, or a ventilation hole penetrating near the trapezoidal part protruding from the center of the bottom of the baby bottle; A "baby bottle" in which a gasket fitted around the trapezoidal part has a groove on the surface facing the ventilation hole, and the ventilation hole can be closed by screwing in a valve body that joins with the gasket.
(Utility Model Application Publication No. 49-44590) is already known.

However, in the former case, the gasket surface that closes the vent is flat, so the vent is either fully open or fully closed, making it impossible to adjust the amount of outside air introduced. Also, the latter is
There is a risk that the screwed-in valve body and gasket may rotate together, causing the groove and the vent hole to become misaligned, and the surface of the gasket that comes into contact with the vent hole is still flat, so the amount of outside air introduced must be adjusted as in the former case. I can't.

In any case, with these baby bottles that do not have the ventilation adjustment function, it is impossible to adjust the amount of suction per unit time, which varies depending on the amount of outside air introduced. If left untreated, there were problems such as the possibility that the infant would suck up too much milk and choke.

The purpose of the present invention is to adjust the amount of outside air introduced according to the sucking force of the infant, and to ensure the optimum amount of suction for the infant.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has a cylindrical part protruding from one side of the main body of the baby bottle, which screws the pressure regulating cap so as to allow ventilation, and a resilient valve with a concave groove on the surface. A method was used in which a plate was housed in the inner bottom surface of the pressure regulating cap, and the groove was continuously deformed by screwing the pressure regulating cap.

[Effect]

In the present baby bottle, if the pressure regulating cap is screwed tightly, the valve plate will be compressed between the cap and the cylindrical part, and the groove will be deformed, gradually narrowing the outside air introduction passage and eventually blocking it, preventing ventilation. Completely cut off. On the other hand, if the pressure regulating cap is gradually loosened when the baby bottle is under negative pressure, the recessed groove that has been pressed and deformed will be restored due to the elasticity of the valve plate itself. It has the effect of being introduced through the groove.

〔Example〕

Hereinafter, the configuration of the proposed nursing bottle will be described in more detail according to the embodiment shown in the drawings. 1 is a nursing bottle main body, and a cylindrical portion 1a is protruded at an appropriate position to enable communication with the outside air. It is. Further, 2 connects the lower flange 2a to the opening 1b of the bottle main body 1 via the attachment ring 3.
4 is a pressure regulating cap, which is screwed into the cylindrical portion 1a of the bottle main body with a gap s.
A valve plate 5 made of a soft elastic material such as silicone is fitted and housed on the inner bottom surface of the cap. As shown in FIG. 2, this valve plate 5 has a concave groove 5a in the shape of one or a cross, which serves as an introduction path for outside air, on the surface that comes into contact with the distal end surface of the cylindrical portion 1a.
is provided.

Note that 7 in the figure indicates a reinforcing ring that is fitted to the bottom of the bottle main body 1, if necessary.

Next, we will discuss how to use the nursing bottle of the present invention and how it works.If the pressure regulating cap 4 is tightly screwed onto the cylindrical portion 1a, the valve plate 5 will come into contact with the tip of the cap and the cylindrical portion, as shown in FIG. As the pressing force increases, the groove 5a is gradually deformed in the direction of narrowing, and is eventually closed, completely blocking the introduction of outside air (Fig. 3A). reference).

On the other hand, when the inside of the baby bottle is under negative pressure, if the pressure regulating cap 4 is loosened and the pressure on the valve plate 5 is released, the concave groove 5 deformed by the elasticity of the valve plate 5 itself
a is restored to its original shape, outside air is introduced into the bottle main body 1 using the concave groove 5a and the screw engagement gap s as an outside air introduction path, releasing the contraction of the nipple 2 caused by the negative pressure state and releasing the milk. This increases the amount of absorption (see Figure 3B).

By the way, if the concave groove 5a is left fully open, it may cause the infant to suck and choke on milk excessively, but according to the present nursing bottle, the pressure regulating cap 4 is screwed in an appropriate amount and the valve plate 5 is closed. By changing the shape and narrowing the concave groove 5a to adjust the amount of outside air introduced, it is possible to obtain the amount of sucking and drinking that is appropriate for each individual infant.

Note that the amount of suction can be continuously adjusted within the range from when the groove 5a begins to deform until it is closed.

In addition, the pressure regulating cap 4 is designed to prevent the bottle from being lost during cleaning or from being swallowed by infants.
One end is rotatably fixed to the pressure regulating cap 4 via a connecting member, and the other end is attached to the mounting ring 3 or ring as a stop ring that can be fitted to the mouth 1b of the bottle main body 1 or the outer periphery near the bottom surface. 7, as shown in FIG.
It may be rotatably inserted through the base of a. In this case, the present invention is also applicable to a structure in which the cylindrical portion 1a is attached to the bottom surface of the main body of the baby bottle, which is formed in the shape of an upper base.

[Effect of idea]

As mentioned above, the present nursing bottle has a concave groove that serves as an introduction path for outside air on the surface of the valve plate attached to the pressure regulating cap, and this concave groove can be opened and closed in stages. It is now possible not only to simply send outside air into the nursing bottle, which has become under negative pressure due to sucking, but also to continuously adjust the amount of outside air introduced according to the infant's suction force. This makes it possible to ensure the optimal amount of absorption.

In addition, since the pressure regulating cap is attached to the main body of the bottle, which has a simple structure, the baby bottle itself can be mass-produced mechanically and can be supplied at low cost, which provides excellent effects.
