Description

Specification

Technical field

The present invention relates to a baby bottle as a childcare product, and more particularly to a baby bottle provided with a tube or tube for delivering a beverage inside a bottle for storing the beverage. Background art

In general, the requirements for baby bottles include:

The material must be safe for food hygiene.

Good adhesion and good cleaning.

The bottle must be of a shape that does not pose a physical hazard to infants and the bottle itself should be light. The contents must be visible.

Etc. as basic requests,

The shape must be easy to hold.

The contents should not leak if the bottle falls.

Easy filling of beverages.

Can be babies in any posture.

All contents can be used.

S should be provided according to infants' motivation.

Do not interfere with infants' independent baby activity. And so on.

With the availability of a wide variety of resin materials today, the basic requirements for baby bottles can be seen to have almost been achieved, but the demands for their use have been fully achieved. Can not. Is this a baby that attaches a dummy nipple to the mouth of the bottle? Due to the K-field of the functions that the basic configuration of the I bottle can perform, it is necessary to add some components to the basic configuration to overcome this limitation. Therefore, next, such an example is related to the object of the present invention. Here are two examples.

The component to be added is a ball valve 11 (see No. 6S, Japanese Utility Model Publication No. 58-16751).

In addition, the names and reference numerals of the components of the baby bottle shown in this publication are based on the examples in the publication because they are convenient for reference.

When the baby * 1 is turned down during lactation, or when the baby is sucked off the feeding site 1 by mistake, the milk that has entered the nipple 2 momentarily vigorously flows through the small hole at the tip of the nipple 2. The purpose is to keep the baby's face, clothing, bedding, etc. from getting dirty, and to achieve this purpose, a control valve is placed near the base of the nipple 2 and the baby bottle. It is provided. The control valve includes a dish-shaped partition plate 5 attached so as to be superimposed on the base flange 4 of the nipple 2, a bottom lid 8 that forms a valve chamber between the dish-shaped plate 5, and a ball valve to be loaded into the valve chamber. 1 1. A bottom frame 6 protrudes from the center bottom of the dish-shaped B plate 5, and the bottom lid 8 is fitted to the bottom frame 6 so as to be freely attached. In addition, the exhibition frame 6 is formed with a buckle 7 that expands downwardly in a wobble shape, and the bottom wall 8 is formed with an introduction hole 9 that expands upwardly in a wobble shape. , Formed by the IS port 7 and the introduction hole 9.

Therefore, the cross-sectional shape of the valve chamber is a ball having a large diameter portion at the center as shown in FIG. 7, and the opening 7 functions as a valve seat. In addition, although there is no direct description about the existence of a pressure reducing hole for sending air equivalent to the amount of consumed milk into the baby bottle 1 or the material of the ball valve 11 and the spirit, Regarding the specific gravity of the valve 11, "it is automatically closed by the weight of the ball valve 11 ... From the description of j etc., it is understood that it is at least large in size.

When the baby bottle 1 according to the above configuration is turned down, the ball valve 11 comes into close contact with the valve seat due to the pressure of the milk that enters the place when the squirrel and the sword are turned down. By closing 7, the intended purpose is achieved, but the same applies to milk bottles with non-return valves, not to the religious ranch 1 The disadvantage is that it is not possible to supply a sufficient amount of milk according to the desire of the person. In short, infants who are new to birth tend to have a short delivery period when feeding because they do not breathe properly, but as they grow up, they become more powerful babies with long cycles. In other words, the amount of milk to drink in a breath can be tolerated. It will be lost.

As another disadvantage, the leakage of milk immediately after the baby bottle 1 has fallen can be effectively prevented by the action of the ball valve 11. There is a drawback that it is not possible to prevent the leakage of milk when left unattended. This is because, as shown in Fig. 6, the flow of milk in the baby bottle 1 stops and the ball valve 1 with a large specific gravity As a result, 1 falls into the center of the valve stem and stabilizes in the state where the mouth 7 is thrown. As a result, it is not possible to prevent the leakage of milk over time.

Next, a description will be given of a case where the added component is the suction pipe 6 (see FIG. 7; Japanese Utility Model Publication No. 55-55771).

It should be noted that the names and reference numerals of the respective parts in the milk bottle described in this publication are based on the examples in the publication.

The baby bottle is intended to cope with the infant's feeding posture depending on the growth stage, and the suction pipe 7 is attached from the nipple 4 to the inside of the bottle 5 so as to hang down. As a result, infants who can drink milk with their own bottles can inhale the entire amount of stored milk without the unnatural posture of lifting the bottom of the bottle 5 greatly. It is devised so that it can be done. In addition, the suction pipe 7 is detachable, and by removing the suction pipe 7, it is possible to cope with infants who cannot hold a baby bottle by themselves.

The baby bottle with such a configuration mainly has a drawback that it cannot cope with the nursing behavior of the mother with the assistance of a mother, and cannot attain a sufficient market position similarly to those having the control valve. In other words, the mode of infants 'babies' behavior and lactation behaviors by mothers are quite diverse. Not necessarily. In addition, it can be said that light S that is scattered on a daily basis is used to encourage the baby to sleep and let the mother fill the milk bottle with it. In general, a milk bottle in which a suction pipe 7 is dropped inside the bottle body 5 is supplied with milk from the bottom of the bottle body 5 through the suction pipe 7, and as shown in FIG. In addition, when the baby bottle is turned downwards, the milk accumulates in the bottle and the air moves to the bottom, making it impossible to suck the milk. Therefore, this type of pill bottle can be used to change the posture of a baby bottle, which often differs between lactation and lactation. It is not possible to supply milk stably while responding to the above.

The present invention provides a desired effect as a result of adding another configuration to the basic configuration of a baby bottle in which a pseudo nipple is attached to the mouth of the bottle as in the above conventional milk bottle. In the conventional circumstance of presenting a new defect caused by the added configuration, the effect that would be caused by the added configuration greatly exceeds the lack that would be caused by the added configuration, Alternatively, breastfeeding, while using as a criterion the adoption of a new configuration, is to be able to reduce the number of chips that would be generated due to the configuration to be added to negligible when using a baby bottle. Even if the baby bottle is turned downward, the milk does not squirt, and there is no leakage of milk even if the baby is thrown in a falling posture. of An object of the present invention is to obtain a baby bottle that can cope with changes in religion behavior with growth. Disclosure of the invention

The present invention employs the following means for the S problem.

The means comprises a resin bottle for storing a beverage, a flexible pseudo-nipple having a suction hole and attached to the mouth of the bottle, and a nozzle hole. The nipple is provided with a separator to be interposed in the field, and one end is connected to the nozzle hole of the separator, and a flexible tube is attached with a heavy weight. The gist is to have a length that reaches the bottom of the bottle and to bend as the weight attached to the tube moves.

In the baby bottle having such a configuration, the beverage that moves toward the mouth of the bottle when the baby bottle is tilted downward is blocked by the separator, so that the beverage does not flow into the pseudo nipple at a stretch. Eliminating the situation in which the beverage spouts from the drinking hole of the pseudo nipple during breastfeeding. Although the separator is provided with a nozzle hole, a tube is connected to this nozzle hole. Therefore, in the case of the M relationship with the beverage that moves to the bottle mouth at a stretch, the nozzle hole is a tube. The presence of the nozzle hole does not impede the brewing prevention of the beverage. In addition, the beverage flow path is elongated as a whole by the intake / drainage holes of the pseudo nipple, the nozzle holes of the separator, and the tubing that are connected in series, and since there is no pressure reduction hole, In the natural state, the beverage inside the bottle and the outside air are not exchanged, and the beverage can be prevented from flowing out from the milk supply bottle released in the inverted ffl state over time.

Here, ¾When the milk bottle is in the upright posture, the beverage inside the bottle accumulates on the bottom side of the bottle, and the end of the bendable tube attached to the nozzle hole is attached to the bottle by the weight of the weight. Move to the bottom side. On the other hand, when the baby bottle is in an inverted posture, the beverage inside the bottle irrigates toward the mouth of the bottle, the weight moves to the mouth of the bottle, and the other part of the tube is closed by the heavy sleep. Move to the side, that is, regardless of the posture of the baby bottle, the tube of the tube can be moved to the position where the beverage is irrigated in that posture, thereby enabling the supply of the beverage.

In addition, an inner hole that communicates with the inner hole of the tube can be formed in the Zhong. The inner hole of the weight opens toward the lower part where the milk accumulates, which makes it possible to effectively match the position of the weight with the position of the end of the tube. It is possible to use up the entire amount of beverages. BRIEF DESCRIPTION OF THE FIGURES

In order to explain the present invention in more detail, embodiments of the present invention will be described with reference to the accompanying drawings.

The baby bottle 10 comprises a bottle 11, a screw cap 12, a dustproof cap 13, a separator 14, a simulated nipple 15, a tube〗 6, and a weight 17 (first 10, second @).

The bottle body 11 is obtained by blow molding a side surface 11a, a bottom surface 11b, a scrap portion 11c, and a bottle mouth portion 11d integrally from a highly transparent resin material. 0). The cross-sectional shape of the VS surface 1a is not circular, but as a result of pursuing ease of holding, the three surfaces that are relatively wide, and the two narrow surfaces that are located at the tops of the triangles formed by these three surfaces, From 9 faces with a total of 6 faces Li, as a whole, 3 have a shape as chamfered rectangular apexes by a narrow dihedral of each width, therefore, also _β is such a shape in the yard surface 1〗 b are as appears, side 1 1 a is squeezed into a circle with enough snow to secure a predetermined internal volume, and a shoulder 11c is formed in this area. The stool surface 11a formed with the shoulder 11c is further raised into a cylindrical shape to form a bottle mouth 11d. In addition, the bottle body 11 is formed thin except for the bottle mouth »11d, and is appropriately elastically deformed. An external thread 11 s is provided on the external surface of the bottle mouth 11 d (3rd S).

The screw cap 1 2 is a colored S-shaped body formed by integrally molding the upper bottom surface 1 2 b and the stepped cylindrical ffl surface 12 a into a relatively thick wall. 2a is provided with a female screw 12s on the inner surface, and a central hole of the upper bottom surface 12b is provided with a through hole H1 of a large mouth S (FIG. 1, FIG. 2). Figure). On the other hand, the dustproof cap〗 3 is a colorless dome-shaped body, and can be tightly fitted to the surface〗 2a of the screw cap 12. In addition, the stepped portion of the inverted surface 12 a of the screw cap 12 serves as an abutting surface for the ridges, which enhances airtightness and has a function of determining the position of the dust-proof cap 13. A nipple 15a with a drinking hole H2 at the top, a sore base 15b, and a brim〗 5d are integrally formed from a resilient resin material with a resilience. (Fig. 2). The outer diameter of the flange〗 5 d is equivalent to the inner diameter of the screw cap 12, and the maximum diameter of the 捥 -shaped base 15 b is the maximum diameter of the through hole H 1 provided on the upper bottom surface〗 2 b of the screw cap 1 2 It is equivalent to diameter. However, a rib 15c for retaining is protrudingly provided on the base 15b alongside the dance 15d.

The separator 14 is provided with an annular body〗 4 c for positioning the pseudo nipple 15 on the upper surface of the circular base plate 14 b, and is positioned on the lower surface with the bottle 11. And a ring 14a. Here, the dimensional relationship between the members is as follows: the outer diameter of the bottle mouth 1〗 d is equal to the outer diameter of the base plate 14b, and the inner diameter of the bottle mouth 1 1d is the outer diameter of the body 14a. equal. Also, the outer diameter of the base plate 14b is the pseudo nipple 15 !? The outer diameter of the ring〗 4 c is equivalent to the inner diameter of the ring-shaped base 15 b. The base plate 14b is provided with a decompression hole H6 located between the ring 14a and the ring 14c, and is in contact with the lower center S of the base plate 14b. The kneading plug 14d is protruded, and a nozzle hole H3 is provided in this portion (FIG. 2, FIG. 30). Reference numeral 17 denotes a small-diameter sphere obtained by wrapping a metal core in a resin material.

A connection plug 17 d protrudes from 17, and an inner hole H 5 penetrating the weight 17 from this portion is formed. The tube 16 is an S-bendable thin tube made of a soft tree material similar to the artificial nipple 15, and one end thereof is connected to the connection plug 14 d of the pace plate 14 b, The end is connected to the connection plug 17 d of the weight 17. Therefore, the nozzle hole H3 communicates from the inner hole H4 of the tube 16 to the inner hole H5 of the weight 17.

These boar members described in sequence include a separator 14 placed on the upper end surface of the bottle mouth 1 1 d of the bottle body 1, a dummy nipple 15 placed thereon, and a screw cap 12 kneaded. By attaching it, it can be assembled very easily (Fig. 3).

The reason is that the bottle 11, the separator 14, and the pseudo nipple 15 are formed by the ring 14 a and the ring 14 c provided on the upper and lower surfaces of the separator 14. The screw cap 1 2 is positioned autonomously by the shape of the juicy base 15 b and the through-hole H 1. Is fixed in the correct position.

Once assembled in this way, the rib 15c prevents the pseudo nipple 15 from dropping off the screw cap 12, so that both can be handled simultaneously as a single unit.

The tube # 6 has a length that reaches the bottom surface 11b of the bottle body 11 with a margin in this assembly completed state. Here, as shown in this example, when the weight 17 has the inner hole H5, the length of the tube 16 includes the length of the inner hole H5, and the weight 1 If 7 has no bore H5, the length of tube 16 shall be its own length.

What is important here is that, in the baby bottle 10 in the assembled state, the decompression hole H6 formed in the separator 14 has the pseudo-nipple 15 !? It means that it is blocked from the outside by the part 15d. In other words, the pressure-reducing hole H 6 does not function in a direction in which the outside air is introduced into the bottle body〗, and only releases the internal pressure when the screw cap 12 is tightened to the outside, so that The purpose is to prevent milk and the like in the body 11 from spouting from the contact portion of each city material. Uniquely elucidating the supply mechanism of the beverage filled in the «milk bottle» 0 is that the «milk bottle 10 appearance», the elastic deformation of the bottle body 11 and its rotation during use «Force, change in internal volume due to sexual deformation of tube 16, pseudo nipple 15» sexual deformation and its resilience, sucking, sunning, etc. Although it is generally difficult for the BB, here, we ignore the trivial factors that spread on the branches and leaves, and use only basic factors to control the basic beverage supply in the normal use position of the «milk bottle〗 0>. An overview of the mechanism is explained.

The baby bottle 10 is normally used in a slightly downwardly inclined position (4th S). At this time, the plate 17 sinks and stops at a position where the elasticity of the tube 16 and the force of contact with the inclined surface 11a of the bottle body 1 are balanced.

In use, first, the side 11a of the bottle 11 is slightly pressed and deformed (indicated by the two-dot chain line in (A)), the internal pressure P2 of the bottle 11 rises to the external pressure P1. The milk M in the bottle 11 is injected into the pseudo nipple 15 from the nozzle hole H3 via the tube 16 and is spilled therein. Here, when the bottle 11 held down is released, the deformed surface 11a recovers to its original shape, so that the internal pressure P2 of the bottle 11 is reduced to the external pressure P1. The outside air is drawn into the dummy nipple 15 from the intake / drainage hole H2, and the air A in the dummy nipple 15 moves into the bottle body 11 through the tube # 6. Here, since the internal pressure P2 and the external pressure P1 are balanced, the movement of the air A and the milk M is stopped, and the milk M does not leak even if the baby bottle 10 is left as it is. It is preferable that the baby bottle 10 is given to the infant after such preparation.

Next, when the infant BBs the dummy nipple 15 from the direction of the arrow YKY 1 (Same country (B)), the internal pressure P 3 of the dummy nipple 15 is temporarily increased, and the empty space in the dummy nipple 15 is changed. A is fed into the bottle 1 チューブ via the tube 16, and the milk M in the dummy nipple 15 is supplied into the mouth of the baby. Here, when the dummy nipple 15 is released, the outside air is drawn in from the intake and drinking hole H2, and the dummy 11 is simulated from the side of the bottle 11 that has been surrounded by the internal pressure P2 by the air A that has been sent earlier. Milk M is replenished in the nipple 15 and, as a result, the amount of air A and milk M in the simulated nipple 15 returns to the above-mentioned ready state.

Here, consider the case where the infant sucks the pseudo nipple 15. In this case, the nipple 15 is deformed so that the nipple 15 can be squeezed as in the case of the wrapping. The internal pressures P 2 and P 3 of the similar nipple 15 are both lower than the external pressure P 1. Therefore, when the pseudo nipple 15 is opened, the outside air is drawn from the drinking and drinking hole H2, and the air A drawn into the pseudo neck 15 continues to flow into the bottle 11 through the tube 16. The internal pressure P2 and the external pressure P1 are balanced in this state. Therefore, if the sucking baby sucks and drinks, the balance between the internal pressure P 2 and the external pressure P 1 is broken, and the milk M that has been overtaken in the simulated nipple 15 is supplied to the baby's mouth, Milk M is replenished into the dummy nipple 15 from the bottle 11 side. Then, the dummy nipple 15 is released, and the baby bottle 11 can return to the ready state again (再び闳 (B)).

The basic operation of the baby bottle 10 according to the present invention is as described above. Here, a specific operation example will be described.

This baby bottle 10 can use all the milk S stored in the upright posture (FIG. 3). This is because the weight 17 has an inner hole H5 communicating with the inner hole H4 of the tube 16, and the weight 17 always moves to the low position where the milk M moves. . Therefore, can you feed yourself with a baby bottle 10 on your own? It does not impair the independence of the L child, and is extremely convenient for raising children who do not eat or drink because they are facing upward due to their structure or habits.

In addition, the rein milk bottle 10 can use the entire amount of the milk M stored in the inverted posture (¾5). The configuration in which the tube 16 is bendable and has a weight 17 at the other end thereof enables an operation such that the tube 16 is turned upside down as shown in FIG. Therefore, the milk M moved to the bottle mouth 11 d can be supplied to the outside by setting the baby bottle 10 to the inverted posture. In other words, the provision of tube 16 completely avoids the new drawbacks that may arise. This is because not only the mother and other caregivers can concentrate on breastfeeding without worrying about the posture of the baby bottle 10, but also because the baby inadvertently inhales the air in the bottle 11 Milk return can be effectively prevented.

In the above description, the name of the resin material for forming each member is not specified, but this is because special materials are not required for manufacturing the baby bottle # 0, and safety and durability are not required. With traditionally used materials that are implemented through use This is the purpose. Note that the tube 16 may be made of the same material as the pseudo nipple 15. Industrial applicability

As described above, the rein milk bottle according to the present invention has no depressurization hole in the sense of supplying air equivalent to the amount of milk or the like extinguished into the bottle body. By inserting a tube between the inside and the outside of the body, air exchange between the inside and outside of the bottle is not performed and the flow of beverage inside the bottle is not affected unless external force is applied, so nursing When the baby bottle is turned down, the milk does not squirt even when the baby bottle is turned down, and the milk does not leak even when the baby is released in the inverted posture, and a flexible tube with a weight attached inside the bottle body is used. By providing, this double-laying will always feed the end of the tube to a place where the milk is rinsed, so that it is possible to feed or milk the whole milk in any position and therefore to the growth of the infant Handles any accompanying salivary behavior Rukoto can.
