Description

Baby pacifier

[0001] The embodiments disclosed in this specification relate to infant pacifiers, and more specifically, to infant pacifiers capable of allowing an infant to suck on the pacifier.

[0002] Generally, pacifiers are used to soothe infants because infants whose teeth have not yet grown can obtain satisfaction and relieve anxiety solely through the act of sucking.

[0003] A conventional infant pacifier, like the artificial pacifier disclosed in Korean Published Patent Application No. 10-2024-0113846, comprises a nipple inserted into an infant's mouth, a shielding portion formed with an area larger than the infant's mouth to prevent the nipple from being sucked into the infant's mouth, and a housing that secures the nipple to the shielding portion.

[0004] Here, the nipple of a conventional pacifier is formed of a silicone-based resin that is harmless to the human body and soft to protect the infant's mouth, and the shielding part is formed of a material that is hard because it fixes the nipple together with the housing.

[0005] However, conventional pacifiers have a problem in that the shielding part that contacts the infant's facial skin is formed of a hard material, causing irritation to the infant's skin.

[0006] In addition, conventional pacifiers have a shielding portion formed with a curvature corresponding to the curvature of an infant's face, which causes contact with the facial skin over a large area, thereby irritating the skin. Furthermore, because it blocks air circulation in the contact area, there is a problem of the infant's skin becoming chafed.

[0007] In addition, conventional pacifiers have the problem that it is difficult to clean the inside of the nipple, and water accumulates in the part where air enters the nipple.

[0008] Therefore, technology was needed to solve the aforementioned problems.

[0009] Meanwhile, the aforementioned background technology is technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot be considered as prior art disclosed to the general public prior to the filing of the present invention.

[0010] The embodiments disclosed in this specification aim to provide an infant pacifier in which a shield portion that prevents the nipple from being sucked into the infant's mouth is formed from a plurality of materials having different hardnesses, so that the hardness of the portion in contact with the skin and the hardness of the portion where the nipple is fixed can be formed differently.

[0011] In addition, the embodiments disclosed in this specification aim to provide a pacifier for infants that can minimize the surface area of ​​the shield portion in contact with the infant's facial skin.

[0012] In addition, the embodiments disclosed in this specification aim to provide an infant pacifier capable of allowing air to circulate to the portion in contact with the infant's skin formed in the shield portion.

[0013] In addition, the embodiments disclosed in this specification aim to provide an infant pacifier that can easily and securely fix a nipple portion to a shield portion without the need for a separate attachment member.

[0014] In addition, the embodiments disclosed in this specification aim to provide an infant pacifier that allows air to flow smoothly through the hollow of the spout and prevents water from accumulating during cleaning.

[0015] As a technical means for achieving the aforementioned technical problem, an infant pacifier according to one embodiment comprises: a nipple portion made of silicone material having a nipple shape with a hollow formed inside, wherein the front end is inserted into the infant's oral cavity and the rear end has a flange portion formed with an expanded outer diameter; a shield portion formed in a plate shape having an outer diameter larger than that of the nipple portion and coupled to the nipple portion to contact the infant's skin; a nipple fixing portion coupled to the flange portion of the nipple portion to allow air to circulate in the hollow of the nipple portion and coupled to the shield portion to fix the nipple portion to the shield portion; and a handle portion coupled to the nipple fixing portion, wherein the shield portion is formed of a plurality of materials having different hardnesses so that the hardness of the portion coupled to the nipple fixing portion and the portion contacting the infant's skin may be formed differently.

[0016] Additionally, the shield portion may include: a shield plate body formed of a material having a relatively low hardness, having a plate shape having a predetermined size and curved with a predetermined curvature to contact the skin of an infant, and having a through hole into which the tip portion is inserted; and a fixing holder formed of a material having a higher hardness than the shield plate body, having a tubular shape on the outer edge of the through hole and forming a connecting portion of the tip portion, while being integral with the shield plate body.

[0017] In addition, the shield plate body may be made of a material mixed with polyethylene and polypropylene, and the fixing holder may be made of polypropylene.

[0018] Additionally, the shield portion may further include contact wings that are formed by protruding in multiple numbers on the outer edge of the shield plate body to provide a contact area that contacts the infant's skin, and are formed with a curvature that protrudes convexly in the direction of the infant's skin to reduce the contact area with the infant's skin.

[0019] In addition, the shield portion may further include an air circulation hole formed through the shield plate body while adjacent to the contact wing, allowing air to circulate to the contact portion between the contact wing and the infant's skin.

[0020] Additionally, the above-mentioned tip fixing part may include: a fixing ring formed in an annular shape having an inner diameter larger than the flange portion of the tip, which accommodates the tip by wrapping around the flange portion while the tip is fitted, and which is formed with an outer diameter corresponding to the inner diameter of the fixing holder and is fixed to the fixing holder by fitting; and a fixing cap that is detachably coupled to the fixing ring and covers the flange portion of the tip accommodated in the fixing ring, and has a communication tube protrudingly formed to be inserted into the hollow of the tip, thereby allowing air to flow into the hollow of the tip through the communication tube.

[0021] In addition, the communication tube may be formed with a cross-section in which the inner diameter of the inlet gradually expands toward the opposite direction of the fixing ring, while extending toward the fixing ring and being inserted into the hollow of the tip portion while forming an air inlet in the center of the fixing cap.

[0022] In addition, the inlet may have an arc-shaped cross-section with a predetermined curvature, and its inner diameter may gradually expand as it moves in the opposite direction of the fixed ring.

[0023] According to any one of the aforementioned means for solving the problem, a pacifier for infants can be provided in which the hardness of the part in contact with the skin and the hardness of the part where the nipple is fixed can be formed differently by forming the shield part with a plurality of materials having different hardnesses.

[0024] In addition, according to any one of the aforementioned means for solving the problem, the shield plate body in contact with the skin is formed of a material having relatively low hardness, so irritation to the infant's skin can be minimized, and the fixing holder is formed of a material having relatively high hardness, so the tip can be fixed more firmly.

[0025] In addition, according to any one of the aforementioned means for solving the problem, the contact wing formed on the outer edge of the shield plate body is formed with a curvature that protrudes convexly toward the infant's skin, thereby minimizing the contact area with the infant's skin and thus minimizing irritation to the skin, and the remaining part of the shield plate body that is not in contact with the skin is separated from the infant's skin, so that air can be supplied to the skin.

[0026] In addition, according to any one of the aforementioned means for solving the problem, air can be supplied to the contact area between the contact wing and the skin through an air circulation hole formed in a part adjacent to the contact wing, so that the contact area can be prevented from becoming chafed.

[0027] In addition, according to any one of the aforementioned means for solving the problem, the fixing ring and the fixing cap constituting the tip fixing part accommodate the flange part of the tip part and are fixed by fitting into the fixing holder of the shield part, so the tip part can be easily and firmly fixed to the shield part without a separate attachment member.

[0028] In addition, according to any one of the aforementioned means for solving the problem, a communication tube formed in the fixed cap is inserted into the hollow of the spout, allowing air to be smoothly circulated into the interior of the spout. Furthermore, since the inlet of the fixed cap forms an arc-shaped cross-section and the inner diameter gradually expands toward the opposite direction of the fixed ring, the effect of preventing water accumulation in the inlet during cleaning of the spout and the fixed cap can also be expected.

[0029] The effects obtainable from the disclosed embodiments are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art to which the disclosed embodiments belong from the description below.

[0040] A pacifier (10) for infants according to one embodiment can relieve the anxiety of an infant and provide satisfaction by allowing the infant to put it in their mouth and suck on it. As shown in FIGS. 1 and 2, it may be configured to include a nipple portion (100), a shield portion (200), a nipple fixing portion (300), and a handle portion (400).

[0041] The nipple portion (100) is a part that an infant bites and sucks on, and can be formed into a nipple shape having a predetermined length with a hollow formed inside.

[0042] This nipple portion (100) is made of a silicone-based resin material that is harmless to the human body, and the front end of the two longitudinal ends is formed in the shape of a nipple so that it can be inserted into the oral cavity of an infant, and as shown in FIGS. 3 and 4, a flange portion (110) with an expanded outer diameter is formed at the rear end to provide a connection portion with the shield portion (200) and nipple fixing portion (300) described later.

[0043] Here, the tip portion (100) can be formed in various shapes for the front portion. For example, the tip portion (100) can be formed in any shape known in the field of nipples, such as the front portion being formed in a cylindrical shape or a flat shape.

[0044] Additionally, the nozzle (100) may have a suction hole (120) formed in the front portion so that the infant can suck smoothly, and the flange portion (110) may be opened.

[0045] Here, the tip portion (100) may be formed with a hollow, elongated cross-section as shown in FIG. 3, and accordingly, the communication tube (330) formed in the fixing cap (320) described later, as shown in FIG. 4, may also be formed with an elongated cross-section and inserted into the hollow of the tip portion (100). Of course, the hollow of the tip portion (100) may be formed with a cross-section of various shapes, such as a circle, in addition to the elongated shape.

[0046] Additionally, the tip portion (100) may have an unillustrated projection formed on the outer or inner surface to stimulate the teeth when an infant bites it.

[0047] The shield portion (200) is designed to prevent the tip portion (100) from being sucked into the infant's mouth and is formed in the shape of a plate having an outer diameter larger than that of the tip portion (100), so as to be connected to the flange portion (110) of the tip portion (100) and come into contact with the skin around the mouth.

[0048] That is, the shield portion (200) is fixed to the flange portion (110) of the spout portion (100) and positioned on the outer edge of the spout portion (100), so that when an infant sucks on the spout portion (100), it comes into contact with the skin around the mouth, thereby preventing the spout portion (100) from being sucked into the mouth.

[0049] This shield part (200) may be configured to include a shield plate body (210) and a fixing holder (220) as shown in FIG. 3.

[0050] The shield plate body (210) is formed in the shape of a plate having a predetermined size and is a member that prevents the tip (100) from being sucked into the mouth while in contact with the infant's skin, and can be formed with a curvature that can wrap around the face.

[0051] This shield plate body (210) is formed from a material having a relatively lower hardness than the fixed holder (220) described later, so that irritation applied when in contact with the infant's skin can be minimized.

[0052] For example, the shield plate body (210) may be formed from a material that is a mixture of polyethylene and polypropylene. Polyethylene is known to have lower hardness than polypropylene, making it more flexible and having relatively better impact resistance. That is, by being formed from a polyethylene + polypropylene material, the shield plate body (210) can be formed with a relatively lower hardness than if formed from polypropylene material alone.

[0053] In addition, the shield plate body (210) can be formed from a material having relatively low hardness, such as thermoplastic polyurethane called TPU, silicone resin, or rubber material.

[0054] Here, a through hole (211) is formed in the center of the shield plate body (210) so that the tip (100) can be inserted and caught.

[0055] The fixed holder (220) is a component that provides a connecting portion of the tip fixing part (300) so that the flange portion (110) of the tip portion (100) can be fixed via the tip fixing part (300) described later.

[0056] Specifically, the fixed holder (220) is formed in a tubular shape on the outer edge of the through hole (211) while being integral with the shield plate body (210), and can provide a connection part of the tip fixing part (300).

[0057] Here, the fixed holder (220) is formed of a material having a relatively higher hardness than the shield plate body (210), thereby allowing the tip fixing part (300) to be fixed more firmly.

[0058] For example, the fixed holder (220) may be made entirely of polypropylene. Polypropylene is known to be used in applications requiring durability because it has a higher hardness than polyethylene.

[0059] In addition, the fixed holder (220) can be made of any material having a higher hardness than the material forming the shield plate body (210).

[0060] Here, the shield part (200) can be manufactured such that the shield plate body (210) and the fixed holder (220) are formed as a single unit by molding two materials having different hardnesses using a double injection molding method.

[0061] For example, the shield part (200) can first inject a fixed holder (220) by introducing a polypropylene material into the mold, and then additionally inject a material mixed with polypropylene and polyethylene into the mold while the fixed holder (220) is in the mold, thereby injecting the shield plate body (210) as a single unit with the fixed holder (220).

[0062] Meanwhile, the shield portion (200) may be configured to further include contact wings (230) that are formed protruding in multiple numbers on the outer edge of the shield plate body (210), as shown in FIGS. 3 and 4.

[0063] The contact wing (230) is formed protruding from the outer edge of the shield plate body (210) to provide a contact area that contacts the infant's skin, and is a component for reducing the contact area with the infant to a minimized state.

[0064] Here, the shield plate body (210) can be formed in the shape of a roughly square plate, and the contact wing (230) can be formed to protrude outwardly away from the through hole (211) at each vertex portion of the shield plate body (210).

[0065] These contact wings (230) are formed with a curvature that protrudes convexly downward in the drawing as shown in FIG. 5, that is, a curvature that protrudes convexly in the direction of the infant's skin, thereby reducing the contact area with the infant's skin by contacting the infant's skin.

[0066] Accordingly, the shield plate body (210) contacts the infant's skin through a plurality of convexly protruding contact wings (230), thereby minimizing skin irritation.

[0067] Meanwhile, the shield portion (200) may be configured to further include an air communication hole (240) as shown in FIGS. 3 and 4.

[0068] The air circulation hole (240) is a component for preventing chafing of the contact area by allowing air to circulate between the contact wing (230) and the infant's skin.

[0069] Specifically, the air communication hole (240) is formed through the shield plate body (210) while being adjacent to the contact wing (230), thereby supplying air to the contact portion between the contact wing (230) and the infant's skin.

[0070] In addition, the air circulation hole (240) can prevent the skin from becoming chafed by allowing air to circulate in the space between the shield plate body (210) and the skin.

[0071] The tip fixing part (300) is a component for fixing the aforementioned tip part (100) to the fixing holder (220) of the shield part (200) as shown in FIG. 6, and is a component that is coupled to the flange part (110) of the tip part (100) and allows air to flow into the hollow of the tip part (100).

[0072] Specifically, the knob fixing part (300) may be configured to include a fixing ring (310) and a fixing cap (320) as shown in FIGS. 3 and 4.

[0073] The fixing ring (310) is a member that is fixed to the fixing holder (220) of the shield portion (200) while receiving the flange portion (110) of the tip portion (100) in a manner that wraps around it.

[0074] Specifically, the fixing ring (310) is formed in an annular shape having an inner diameter larger than the flange portion (110) of the tip portion (100), so as shown in FIG. 6, the tip portion (100) can be fitted and received in a shape that surrounds the flange portion (110), and is formed with an outer diameter corresponding to the inner diameter of the fixing holder (220) so that it can be fixed by fitting into the fixing holder (220).

[0075] Accordingly, the tip portion (100) is fixed to the fixing holder (220) of the shield portion (200) while being received in the fixing ring (310), so that it can be firmly fixed without an adhesive or a separate fixing member, and can be easily separated from the fixing holder (220) of the shield portion (200) for cleaning.

[0076] The fixing cap (320) is a component that accommodates the flange portion (110) of the tap portion (100) together with the fixing ring (310) and allows air to pass through the hollow of the tap portion (100).

[0077] Specifically, the fixing cap (320) is formed in an annular shape like the fixing ring (310) and is detachably coupled to the fixing ring (310) to cover the flange portion (110) of the tip portion (100) received in the fixing ring (310).

[0078] Additionally, as shown in FIG. 4, the fixed cap (320) has a communication tube (330) formed protruding from the center of the annular shape and is inserted into the hollow of the tip portion (100), thereby allowing air to be circulated into the hollow of the tip portion (100) through the communication tube (330).

[0079] These fixing caps (320) are connected to the top of the fixing ring (310) in a press-fit manner and can accommodate the flange portion (110) of the tip portion (100) together with the fixing ring (310).

[0080] Here, the communication tube (330) formed in the fixed cap (320) can be inserted into the hollow of the tap portion (100) by extending in the direction of the fixed ring (310) while forming an air inlet (331) in the center of the fixed cap (320) as shown in FIG. 3, and can be inserted into the hollow of the tap portion (100) by forming an elliptical elongated cross-section corresponding to the shape of the hollow of the tap portion (100).

[0081] Additionally, the communication tube (330) may be formed with a cross-section in which the inner diameter of the inlet (331) gradually expands toward the opposite direction of the fixing ring (310).

[0082] That is, the inlet (331) of the communication tube (330) can be formed in a shape that expands through an inclined surface that widens as it moves in the opposite direction of the fixed ring (310).

[0083] Accordingly, the inlet (331) gradually narrows in the direction of the tap (100), thereby increasing the speed of the incoming air according to Bernoulli's principle, and thus allowing air to flow smoothly into the hollow of the tap (100).

[0084] Here, the inlet (331) can be formed with an arc-shaped cross-section having a predetermined curvature, with an inclined surface that widens as it moves toward the opposite direction of the fixed ring (310).

[0085] Accordingly, since the fixed cap (330) is formed as a curved surface without a step at the inlet (331), water accumulation during washing is prevented and smooth drying can be expected.

[0086] As shown in FIG. 6, the handle portion (400) can be rotatably coupled in a state interposed between the fixing ring (310) and the fixing cap (320) constituting the knob fixing portion (300) to provide a handle that can be grasped by an infant.

[0087] A method of use for an infant pacifier (10) according to one embodiment including the above-mentioned components is described.

[0088] The infant puts the tip of the knob (100) into their mouth and sucks while holding the handle (400).

[0089] At this time, external air can be introduced into the hollow of the tap portion (100) through the inlet (331) of the communication tube (330) formed in the fixed cap (320), and can be introduced smoothly into the hollow of the tap portion (100) as the diameter of the inlet (331) gradually narrows toward the tap portion (100).

[0090] Meanwhile, the shield part (200) can prevent the nipple part (100) from being sucked into the infant's mouth by coming into contact with the skin around the infant's mouth when the infant sucks on the nipple part (100).

[0091] At this time, the shield portion (200) can minimize irritation to the infant's skin by contacting the infant's skin through a contact wing (230) that protrudes convexly toward the infant's skin. Additionally, the air circulation hole (240) can prevent skin irritation by supplying external air to the contact portion of the contact wing (230) and the space between the shield plate body (210) and the skin.

[0092] When washing the infant pacifier (10), the nipple portion (100) can be separated from the shield portion (200) together with the nipple fixing portion (300) and washed.

[0093] At this time, the fixing cap (320) constituting the nozzle fixing part (300) can be washed and dried without water accumulation by forming the inclined surface of the inlet (331) as a curved surface.

[0094] As described above, according to one embodiment of the pacifier (10), the shield plate body (210) that comes into contact with the skin is formed from a material having relatively low hardness, so irritation to the infant's skin can be minimized, and the fixing holder (220) is formed from a material having relatively high hardness, so the nipple part can be fixed more firmly. In addition, the contact wing (230) formed on the outer edge of the shield plate body (210) is formed with a curvature that protrudes convexly toward the infant's skin, thereby minimizing the contact area with the infant's skin and thus minimizing irritation to the skin.

[0095] The embodiments described above are for illustrative purposes only, and those skilled in the art will understand that the embodiments described above can be easily modified into other specific forms without altering the technical concept or essential features of the embodiments described above. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.

[0096] The scope of protection sought through this specification is defined by the claims set forth below rather than by the detailed description above, and should be interpreted to include all modifications or variations derived from the meaning and scope of the claims and the concept of equivalents.
