Technical Field

The invention relates to the technical field of infant products, in particular to a feeding bottle and a manufacturing method thereof.

Background

A baby bottle is a very widely used baby product. The nipple is used for containing liquid substances such as milk products and the like, and the liquid contained in the nipple is sucked by a baby. Feeding bottles can be classified into a number of different categories depending on the raw materials from which they are made. Among other things, factors such as weight, portability, manufacturing cost, and manufacturing difficulty are considered. Plastic feeding bottles made of high molecular polymers are currently the most common type.

Feeding bottles, as infant products, are frequently in contact with infants during daily use. Therefore, the raw materials used to make plastic baby bottles must be carefully chosen to avoid the release of toxic substances, such as bisphenol A, during use.

Silicone rubber, as a safe and reliable inert high molecular polymer, is often used in the manufacture of feeding bottles. However, the hardness of silicone rubber is limited, and the task of maintaining a sealed connection between the nipple and the bottle body is difficult to achieve.

In order to avoid leakage during use, the existing feeding bottle uses some hard polymer material instead of silicone rubber at the connecting part to provide enough structural strength to avoid leakage. These hard polymeric materials are generally thermoplastic resin materials (e.g., PP, PC, PBT). Due to its direct contact with the liquid in the bottle, it may release unhealthy chemicals during use, creating a certain risk to the health of the infant.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

For convenience of explanation and understanding of the technical solutions of the present invention, the following descriptions use the directional terms as they are used in the drawings.

Fig. 1 is a schematic structural view of a feeding bottle provided by an embodiment of the invention. As shown in fig. 1, the nursing bottle includes a body 100 and a nipple 200.

The bottle body 100 is a watertight container with an opening at one end, and can be used for containing liquid. A first connecting portion 110 is provided at the top opening of the body 100 to serve as a connecting base.

Specifically, the main body of the bottle body 100 may be made of a soft material, such as silicone rubber. In addition, silicone rubber is also a safe and reliable polymeric material that does not release chemicals to avoid health risks.

The nipple 200 is the portion that the infant sucks on to simulate a nipple during nursing. Correspondingly, a second connection portion 210 adapted to the first connection portion 110 is provided at one end of the nipple 200 connected to the bottle body 100. During use, the nipple 200 may be hermetically connected to the body 100 by the first and second connection portions 110 and 210. Specifically, the nipple 200 may also be made of silicon rubber, so as to meet the health care requirements of the infant products.

It should be noted that the bottle body 100 and the nipple 200 may be configured in any type of shape or size according to the actual requirement, and are not limited herein. For example, a three-dimensional cylindrical shape or a square cylindrical shape.

Preferably, the nursing bottle can be added with one or more different structural units to provide convenience in use. For example, the surface of the body 100 may be further provided with a scale 120 for indicating the volume of the liquid inside to assist the user in brewing powdered milk.

In this embodiment, the scale 120 may be formed by a series of graduation marks marked on the transparent portion, so that the user can read the liquid volume in the current feeding bottle through the corresponding graduation at this time of the liquid level on the bottle body 100.

Fig. 2 is a schematic structural diagram of a first connection portion according to an embodiment of the present invention. Fig. 3 is a schematic structural diagram of a second connection portion according to an embodiment of the present invention. As shown in fig. 2 and 3, in the present embodiment, the first connection portion 110 and the second connection portion 210 both adopt the same multilayer structure, including a support structure (111, 211) and an isolation layer (112, 212).

Wherein the support structure (111, 211) is a support part having a strong stiffness or rigidity. The structure can still be kept from deforming under the states of pressure bearing and the like so as to ensure the sealing property of the connection between the nipple and the bottle body and avoid the leakage phenomenon during use.

In particular, the support structure may be made of a thermoplastic resin or other polymeric material, such as PBT (polybutylene terephthalate) or the like. A polyester material having sufficient structural strength and rigidity after curing.

The isolation layer (112, 212) is a component covering the surface of the support structure for isolating the support structure from external contact.

In some embodiments, the isolation layers (112, 212) of the first and second connection portions 110, 210 may have opposing structural configurations, and when the first and second connection portions 110, 210 are sealingly connected, the isolation layers (112, 212) cooperate to completely cover the support structure with the isolation layers, e.g., the isolation layer 112 of the first connection portion 110 covers an inner side of the support structure. The isolation layer 212 of the second connection portion 210 covers the outer side of the support structure.

In particular, considering that the isolation layer is the part directly contacted with the food liquid, the isolation layer can also be made of safe and reliable silicon rubber materials so as to avoid the risk of the health of the infants.

The first connecting part and the second connecting part cover the isolating layer (112, 212) on the surface of the supporting structure, so that a complete closed space can be formed inside the feeding bottle when the nipple is connected with the bottle body in a sealing mode. The liquid such as the milk powder and the like which is brewed is contained in the closed space and can only be sucked out through the topmost end of the nipple, so that the risk of health hazard caused by the fact that the liquid directly contacts with the supporting structure is avoided.

With reference to fig. 2, in a preferred embodiment, the first connecting portion 110 further includes an extending portion 113. The extension portion 113 is formed with a stepped surface on an outer side surface of the first connecting portion, and is thereby engaged with the top end opening of the body. Such structure setting is favorable to the manufacturing of body, guarantees the sealed effect between first connecting portion and the body.

The feeding bottle provided by the embodiment of the invention has a special structural design, can ensure that the nipple is in sealed connection with the bottle body, avoids leakage, keeps the rigid plastic supporting structure from contacting with liquid contained in the feeding bottle through the arrangement of the isolating layer, and can ensure the health of infants.

Depending on the design of the feeding bottle, the connection between the teat and the body may be of a corresponding configuration. In some embodiments, as shown in fig. 2 and 3, the outer side of the first connection portion 110 and the inner side of the support structure of the second connection portion 210 may be respectively provided with a matching spiral line, so that the nipple 200 and the bottle body 100 can be hermetically connected by means of a threaded connection.

That is, in actual use, the user may screw the bottle body 100 or the nipple 200 in a certain direction to achieve the sealing connection as shown in fig. 6, or after the sealing connection, the nipple 200 may be detached from the bottle body 100 by screwing in the opposite direction.

Of course, in fig. 6, the first connection portion 110 and the second connection portion 210 are described by way of example as being screwed. The surfaces of the first connection portion 110 and the second connection portion 210 can be modified to have different structures, and different types of connection means can be used to achieve the sealing connection between the bottle body 100 and the nipple 200, such as a snap connection.

Fig. 4 is a schematic structural diagram of a nipple 200 according to an embodiment of the present invention. As shown in fig. 4, the pacifier 200 may be substantially semi-spherical in shape with a convex portion at the top to provide a simulated environment for nursing. The method specifically comprises the following parts: a second connection part 210, a nipple body 220, and a mouthpiece 230.

The nipple body 220 is a main structure of the nipple, and may be a semi-spherical shape as a whole. The bottom of the bottle body is provided with an opening, and the size of the opening is matched with that of the top end of the bottle body 100 (namely, the size of the bottom opening is slightly smaller than that of the top end of the bottle body 100). The second connection portion 210 is disposed at an edge of the bottom opening, and is connected to the first connection portion.

It should be noted that the top opening of the body and the bottom opening of the teat body may take any suitable shape or size. In particular, a circular opening with a larger radius may be used to facilitate cleaning of the bottle body and nipple.

A spout 230 is formed extending upward from the nipple body 220 at an end spaced apart from the bottom opening. The mouthpiece 230 may be integrally formed with the nipple body to simulate the nipple portion of a human body. Accordingly, a nipple hole of a proper size for the baby to suck out the liquid inside the baby bottle is provided at the top end of the nipple 230.

In a preferred embodiment, one or more air inlet valves 240 may be provided on the nipple body to avoid choking or swelling of the infant.

The air inlet valve 240 penetrates through the nipple body and allows outside air to flow through, so that the internal pressure and the external pressure of the feeding bottle can be kept balanced at any time, the baby can suck milk more smoothly, and the problems of milk choking, belly expansion and the like are effectively prevented.

An appropriate number of inlet valves may be selected based on different design requirements. Specifically, the air inlet valves 240 may be provided in a pair, and are respectively symmetrically disposed on the nipple main body to ensure the air flow.

FIG. 5 is a schematic structural view of a feeding bottle according to another embodiment of the present invention. As shown in fig. 5, the nursing bottle may include a protective cap 300 in addition to the basic body and nipple.

The bottom end of the protective cap 300 is opened to form a receiving space adapted to the nipple. Corresponding connecting structures, such as outwardly extending latches, may also be provided at the edges of the bottom opening of the protective cap 300 to secure it over the top opening of the bottle body, thereby enclosing the nipple shield within the nipple to protect it from contamination or damage.

It will be appreciated that the protective cap 300, as part of the non-direct food contact, may be made from any type of material, such as the same PBT material as the support structure. The protective cover 300 may be formed in a variety of shapes as required by the design, so long as it forms a space for receiving a nipple.

In order to realize the multilayer structure of the first connecting part and the second connecting part, the embodiment of the invention also provides a manufacturing method of the feeding bottle. Wherein, the manufacturing method can comprise the following steps:

firstly, through a secondary injection molding process, a support structure and an isolation layer covering the surface of the support structure are formed so as to obtain a first connection part and a second connection part.

By "overmolding process" is meant that the cover material is injected over, under, around, and/or within the substrate, etc. during the molding process, and ultimately assembled into a complete part.

Based on the secondary injection molding process, the support structure made of PBT can be used as a base material, liquid silicon rubber is injected on the surface to be covered as a covering material to form an isolation layer covering the support structure, and finally the first connection portion and the second connection portion are obtained.

Preferably, a self-adhesive silicone rubber (self-adhesive silicone, commercially available from seiko chemical) can be used to prepare the isolation layer outside the support structure to form the first connection portion.

It should be noted that the first connection portion and the second connection portion are two portions that match each other. It can be produced by using a proper mould so that the two can be tightly engaged.

Then, on the basis of the isolating layer of the first connecting part, a bottle body with a preset size and shape is manufactured through a forming process, and on the basis of the isolating layer of the second connecting part, the nipple matched with the bottle body is manufactured through the forming process.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
