Description

Tube-integrated baby bottle

[0001] The present invention relates to a tube-coupled infant bottle, and more specifically, to a tube-coupled infant bottle in which a silicone tube is coupled to wrap around the outside of the bottle and configured so that the bottle can be used in a state where the tube is inflated like a balloon, and which improves quality by preventing internal air from the inflated part, which is the part held by the hand, from leaking to the non-inflated part, thereby maintaining a good grip for a long time.

[0002] The tube-integrated infant feeding bottle described above is designed to incorporate a silicone tube that wraps around the bottle body, and to allow the bottle to be used after air is injected into the tube to inflate it evenly like a balloon, thereby enabling the child to experience a sensation (such as touch or temperature) similar to that of a mother's breast milk when using the bottle, thus contributing to comfortable and stable feeding and the child's emotional development.

[0003] Such tube-coupled infant feeding bottles have been disclosed in the past by the present inventors in numerous ways.

[0004] For example, Korean Patent 10-2652235 (hereinafter referred to as "prior art") discloses a silicone tube for a baby bottle cover that allows the baby bottle to land stably when standing upright, ensures that the expansion part of the silicone tube of the baby bottle held by the child during drinking is in an optimal position, and reduces manufacturing costs through a simple structure.

[0005] The silicone tube mounted to wrap around the baby bottle of the prior art described above is characterized by comprising: an upper expansion portion that expands outward by pressure when air is injected, formed as a thin membrane and extending downward from the lower part of a ring-shaped thick portion; and a lower tightening portion that contracts downward from the lower part of the upper expansion portion and expands, formed as a thick membrane, and does not expand when air is injected, thereby maintaining contact with the baby bottle.

[0006] Here, the upper expansion part expands when air is injected, and expands particularly in the area near where the nipple is located, providing the advantage of making it comfortable for the child to hold with their hand when drinking.

[0007] However, this prior art had a problem in that when the baby bottle was used for a long time, the air that flows into the interior of the upper expansion part and provides expansion force gradually leaked into the lower tightening part.

[0008] If air inside the upper expansion part leaks to the outside in this way, the expansion force and elasticity of the upper expansion part decrease, and at the same time, the grip feels poor.

[0009] Therefore, to solve this, one can use an air pump to replenish air into the upper expansion part, but such frequent replenishment of air leads to a problem that degrades the quality of the product.

[0010] The present invention aims to solve the aforementioned problems. The objective of the present invention is to provide a tube-integrated infant feeding bottle with improved quality, wherein a silicone tube is combined to wrap around the outside of the bottle and configured so that the bottle can be used in a balloon-like inflated state, and by fundamentally blocking the leakage of internal air from the inflated part (the part held by the hand) to the non-inflated part, a good grip can be maintained for a long time.

[0011] The present invention, for achieving the above purpose, comprises: a container in which a stopper equipped with a nipple portion is detachably coupled to an upper fastening portion; a tube mounted to surround the container and having a certain elasticity that inflates outward upon air injection, wherein the tube is configured in a sack shape to surround the container and has a mounting hole formed at the top so that the fastening portion protrudes after the container is inserted and mounted; a tightening ring portion formed by thickening the rim of the mounting hole to tighten and connect to the lower end of the fastening portion of the container; an expansion portion formed by extending downward from the tightening ring portion and formed as a thin membrane that expands outward by pressure upon air injection; a non-expansion portion formed by contracting downward from the expansion portion and then extending, which does not expand upon air injection and maintains a state of close contact with the lower and bottom surfaces of the container; an air injection portion formed on one side of the expansion portion; and a sealing ring portion formed by protruding a certain length inward from the boundary line between the expansion portion and the non-expansion portion, which is in close contact with the side of the container and prevents air in the expansion portion from leaking into the non-expansion portion.

[0012] In addition, according to the present invention, the sealing ring portion is configured in a ring shape and is characterized by being formed with an upward slope having a certain angle with respect to the expansion portion formed on the upper side.

[0013] In addition, according to the present invention, a second thick portion is formed at regular intervals at the boundary between the expansion portion and the non-expansion portion where the sealing ring portion is formed.

[0014] In addition, according to the present invention, the second thick portion is formed as a thick film and is characterized by having a sealing ring portion formed in the central portion.

[0015] In addition, according to the present invention, the tube is characterized by forming a boundary line portion at a certain interval in a vertical direction on one side, and forming a transparent portion on the inner side of the boundary line portion.

[0016] In addition, according to the present invention, the transparent part is characterized by having a vertical scale mark printed thereon.

[0017] In addition, according to the present invention, the boundary line portion is characterized by being configured in a zigzag shape.

[0018] As such, the present invention is configured such that a silicone tube is combined to wrap around the outside of a baby bottle, allowing the bottle to be used in a balloon-like inflated state; by fundamentally blocking the leakage of internal air from the inflated portion, which is the part held by the hand, to the non-inflated portion, it provides the effect of improving quality by maintaining a good grip for a long time.

[0029] As described above, the tube-coupled infant feeding bottle (100) according to the present invention is,

[0030] It includes a container (110) in which a stopper (113) equipped with a nipple portion (112) is detachably coupled to an upper fastening portion (111), and a tube (110) that is mounted to surround the container (110) and expands outward by injecting air while having a certain elasticity.

[0031] The above container (110) has the same configuration as a generally known baby bottle and can be configured to have the same specifications.

[0032] The above tube (120) is a characteristic component of the present invention, and the inflated tube, which is made of silicone material, provides a texture and temperature similar to mother's milk when a child uses a baby bottle, thereby contributing to comfortable and stable feeding and the emotional development of the child.

[0033] The above tube (120) is configured in a sack shape to surround the container (110) and has a mounting hole (121) formed at the top so that a fastening part (211) protrudes after the container (110) is inserted and mounted; a tightening ring part (122) formed by thickening the rim of the mounting hole (121) to tighten and connect to the bottom of the fastening part (111) of the container (110); an expansion part (123) formed as a thin film that expands outward by pressure when air is injected and is formed by contracting and expanding below the expansion part (123), a non-expansion part (124) that does not expand when air is injected and maintains a state of close contact with the bottom and bottom surface of the container (110); an air injection part (126) formed on one side of the expansion part (123); and a certain length protruding inward from the boundary line between the expansion part (123) and the non-expansion part (124). It includes a sealing ring portion (127) that is formed and adheres to the side of the container (110) and prevents air in the expansion portion (123) from leaking into the non-expansion portion (124).

[0034] The above tube (120) may be made of a silicone material having a certain elasticity.

[0035] The above tightening ring portion (122) is configured in the form of a thick silicone ring and applies strong pressure elastic force to the mounting hole (121), so that when fitted into the container (110), it is positioned at the bottom of the fastening portion (111) of the container (110) as shown in FIG. 5 and is configured to be tightly sealed so that air does not leak out.

[0036] The above expansion portion (123) is formed by extending to the lower part of the tightening ring portion (122) and is formed as a thin film.

[0037] Therefore, when air is injected, it expands, and the expansion location is a location close to where the nipple part (112) is located, so that the position is appropriate when the child holds it with their hand while drinking.

[0038] In addition, a first thick portion (128) that inhibits expansion is formed in the expansion portion (123).

[0039] The first thick portion (128) is preferably formed at an intermediate position of the expansion portion (123), and a groove is formed so that the middle circumference portion contracts slightly inward when the expansion portion (123) is expanded by air injection, thereby improving the grip when a child holds the expansion portion (123).

[0040] The above non-expanding portion (125) is formed by contracting and expanding to the lower part of the expansion portion (123) and remains non-expanded even when air is injected, maintaining a state of close contact with the lower and bottom surfaces of the container (110). The air injected into the expansion portion (123) is completely sealed by the sealing ring portion (127) and cannot move to the non-expanding portion (125), thereby maintaining a non-expanding structure.

[0041] In addition, the bottom portion (124) of the above-mentioned non-expanding portion (125) is kept in close contact with the bottom surface of the container (110), so that the baby bottle (100) can be stood upright stably.

[0042] The bottom part (124) is configured with a structure in which the central part is sunken inward, so that the baby bottle (100) can be stood up more stably.

[0043] The air inlet (126) is formed on one side of the expansion part (123) and is a hole into which air is injected through an air injector (200) as shown in FIG. 6, and is configured so that the air inside can be discharged to the outside by a pressing action when removing air. The air inlet (126) has a known structure.

[0044] The sealing ring portion (127) is a characteristic component of the present invention and is formed to protrude a certain length inward from the boundary line between the expansion portion (123) and the non-expansion portion (124), and is in close contact with the side of the container (110) to prevent air in the expansion portion (123) from leaking into the non-expansion portion (124).

[0045] The sealing ring portion (127) is configured in a ring shape and is formed to be inclined upward at a constant angle (a) with respect to the expansion portion (123) formed on the upper side.

[0046] The above angle (a) may be composed of an acute angle range, but is not necessarily limited thereto.

[0047] The sealing ring portion (127) is further adhered to the side of the container (110) when expanded by the inflow of air into the expansion portion (123), thereby preventing the air in the expansion portion (123) from leaking into the non-expansion portion (125).

[0048] The sealing ring portion (127) is formed integrally with the tube (120) and may be made of silicone material.

[0049] In addition, a second thick portion (129) may be formed at regular intervals at the boundary between the expansion portion (123) and the non-expansion portion (124) where the sealing ring portion (127) is formed.

[0050] The second thick portion (129) is formed as a thick film and configured so that a sealing ring portion (127) is formed in the central portion (129a).

[0051] The second thick portion (129) firmly supports one end of the sealing ring portion (127), thereby enabling the sealing ring portion (127) to perform the sealing function more efficiently.

[0052] At the same time, the second thick section (129) pressurizes the container (110) with a stronger elastic pressure to prevent the air in the expansion section (123) from leaking into the non-expansion section (124).

[0053] The operation and function of the baby bottle (100) of the present invention configured as described above will be explained below with reference to FIGS. 5 and FIGS. 6.

[0054] First, the mounting hole (121) of the tube (120) is forcibly opened to insert the container (110). This operation is carried out using a designated jig in the factory during product manufacturing.

[0055] Accordingly, when a tube (120) is mounted on the outer surface of the container (110), as shown in FIG. 5, the tube (120) is maintained in a state of close contact with the body of the container (110), and in particular, the tightening ring portion (121) is configured to strongly close the lower end of the fastening portion (111) of the container (110) so that air does not leak out, and the sealing ring portion (127) is maintained in a state of close contact with the side of the container (110) so as to face upward.

[0056] In addition, when a stopper (113) equipped with a nipple portion (112) is attached to the fastening portion (111) of the container (110), the lower portion of the stopper (113) presses against the tightening ring portion (121), thereby further enhancing the sealing function of the tightening ring portion (121).

[0057] In this state, when air is injected into the air injection part (126) of the tube (120) using an air injector (200) as shown in FIG. 6, the expansion part (123) of the tube (120) begins to expand.

[0058] As the expansion portion (123) expands, the sealing ring portion (127) located at the boundary line with the non-expansion portion (125) is separated from the expansion portion (123) but continues to maintain contact (close contact) with the side of the container (110). At the same time, the air flowing into the expansion portion (123) pressurizes one side of the sealing ring portion (127) in the direction of the arrow, thereby increasing the sealing force of the sealing ring portion (127) to the side of the container (110). As a result, the air flowing into the expansion portion (123) is not leaked into the non-expansion portion (125) by the sealing ring portion (127) and the second thick portion (129).

[0059] Therefore, after the appropriate amount of air is injected into the expansion part (123), the expansion part (123) will remain in an expanded state even after a long period of time has passed.

[0060] In addition, when the expansion part (123) expands, a groove is formed around the middle portion by the first thick portion (128), and the groove formed at this time improves the grip when a child holds the expansion part (123).

[0061] Therefore, the present invention prevents the internal air of the expansion part (123), which is the part held by hand, from leaking into the non-expansion part (125), thereby allowing a good grip to be maintained for a long time.

[0062] In addition, the tube (120) of the present invention is configured to form a boundary line section (131) at regular intervals in a vertical direction on one side as shown in (a) and (b) of FIG. 7, and to form a transparent section (132) inside the boundary line section (131).

[0063] The above tube (120) is typically made of silicone material and has an opaque part (133), but is configured to have a transparent part (132) as described above so that the container (110) can be seen.

[0064] A vertical scale mark can be printed on the transparent part (132).

[0065] In addition, the boundary line portion (131) is configured in a zigzag shape so that it can be checked for horizontality when combined with the container (110).

[0066] Meanwhile, although specific embodiments have been described in the detailed description of the present disclosure, it is understood that various modifications are possible within the scope of the present disclosure. Therefore, the scope of the present disclosure should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
