Description

[Technical field]

[0001] The present invention relates to a teeth development device. More specifically, it accurately realizes the shape of a peeled banana, enhancing the aesthetic look, while the banana peel acts as a stopper to prevent the banana from going too deep into the baby's mouth, preventing safety accidents. Furthermore, it is easy to mold, and instead of painting it, different colors (different colors) can be embodied at the same time as molding, further enhancing the aesthetic look. It is also non-toxic to the human body, has excellent bonding properties in the parts embodied in different colors, and does not cause interfacial separation even during heat sterilization, allowing for a long lifespan. The present invention relates to a teeth development device with these improvements. [Background technology]

[0002] Babies start exploring with their hands at around 3 months of age, and their first teeth begin to appear around 6 months of age, at which point they start to feel toothache.

[0003] When toothache starts, it can be itchy and painful as the tooth comes out through a hole, the baby becomes sensitive and the symptoms become worse especially for babies aged 14-16 months as their first molar comes in, the symptoms usually last for around 3 days.

[0004] Teething devices (also known as "teething cages") are often used during this process to aid in oral development through gum stimulation, relieve itching, begin grasping exercises with the hands, and develop small muscles.

[0005] The most commonly used tooth development devices, as disclosed in Patent Documents 1 to 3, are mostly round and circular, which can be held in the hand and water can be poured into the mouth.

[0006] There are also ones shaped like plants or fruits, and they are made from silicone, which is harmless to the human body and has excellent heat resistance.

[0007] In particular, the banana shape has become common among fruit-shaped tooth development devices, as the banana shape is the perfect size for a baby to hold in one hand, and adding protrusions to the skin can help babies develop tooth sensation.

[0008] Not only that, the banana peel is a safety measure to prevent the banana from going too deep into the baby's mouth, the bottom has more protrusions to enhance the baby's teething sensation, and the patterned holes help develop the baby's senses.

[0009] However, as shown in the example of Figure 1, when banana leaves are attached, it is difficult to design the mold, and it looks like a simply peeled banana, which is not aesthetically pleasing and unnatural.

[0010] That is, in terms of mold design, it is difficult to realize a banana peel with a rounded tip that curves downwards, and as shown in the example, the entire peel is raised upwards, making it easy for the slide mold to slip out. Also, there is a limit to only being able to realize an even number of peels, such as two or four, which is unnatural.

[0011] Moreover, since the molding is done by pouring in solid-phase silicon and pressing it with a press, the upper part shaped like leather and the lower part including the leather are molded in two halves, and then the two are bonded by applying heat. This makes the process complicated and requires post-processing due to the occurrence of burrs on the adhesive surface.

[0012] In addition, since it is formed by pressing solid silicon with a press, it is difficult to realize various different colors, so it is mostly released in a single color, or if a different color is realized, it is painted through a separate process. [Prior art documents] [Patent documents]

[0026] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0027] Prior to describing the present invention, the following specific structural or functional descriptions are provided solely for purposes of illustrating examples of the inventive concepts, which may be embodied in various forms and should not be construed as being limited to the examples set forth herein.

[0028] In addition, since the embodiments according to the concept of the present invention can be modified in various ways and can have various forms, specific embodiments are illustrated in the drawings and described in detail in the present specification, but this is not intended to limit the embodiments according to the concept of the present invention to the specific disclosed forms, and it should be understood that the embodiments include all modifications, equivalents, or alternatives included in the spirit and technical scope of the present invention.

[0029] As shown in Figures 2 and 3, the tooth development device according to the present invention includes a banana-shaped press-molded part (100) that a baby can hold in his / her hand, and an injection-molded part (200) that is joined to the press-molded part (100) to form an integral body and that enters the baby's mouth to provide a tooth development function.

[0030] That is, the tooth development device according to the present invention is manufactured in a new way by combining press molding and injection molding, unlike the conventional method which is manufactured only by press molding, and improves moldability and makes it easy to design a mold, allowing free curve expression. Through this, it is characterized by being embodied as close as possible to the real banana.

[0031] In the present invention, it is possible to express three skin parts, and it is also possible to express a skin with a rounded shape toward the bottom, which improves the aesthetics. Above all, injection molding uses liquid silicon, so it is easy to realize colors. It has the advantage of being free to mold different colors, making it possible to express various desired colors without having to paint separately as in the past.

[0032] The press-molded part (100) includes a support part (110), a pillar part (120) erected integrally with the support part (110), and a joining part (130) formed on the upper part of the pillar part (120) to which the injection-molded part (200) is joined.

[0033] At this time, the support part (110) is circular with a number of indentations, for example, in the shape of a petal, rounded so that the baby can feel it, and has a structure in which a number of position fixing holes (112) are formed.

[0034] Here, the position fixing hole (112) is not only an important element for accurately matching the parting surface with the press molded part (100) during injection molding to prevent poor bonding, but also contributes to the development of small muscles when a baby holds it in his / her hands or plays with it between his / her fingers, and also helps the oral cavity develop by stimulating the gums when chewing it, and also helps relieve itching.

[0035] The pillar portion (120) is the main part that the baby grasps with its hands, and serves as a guide to allow the baby to easily grasp, pull, and put the developing portion (210) in its mouth and chew, as well as to enjoy repeatedly grasping and releasing the toy.

[0036] Furthermore, as shown in Figs. 2 and 4, the joint (130) is shaped like a peeled banana and includes an injection groove (132) into which the injection liquid can be injected, and a dam (134) formed in the shape of a jaw around the injection groove (132) to prevent the injected injection liquid from overflowing or forming burrs along the interface.

[0037] This results in an accurate parting line being formed when the injection mold is closed, preventing burrs from occurring, preventing misalignment of the molding surface, and achieving uniform and accurate joining guidance.

[0038] In other words, because such a concept did not exist in the past, it was necessary to focus solely on press molding, and the only technique that could be realized was to thermally attach the developed portion after press molding. However, with the present invention, by realizing the configuration described above, it is now possible to carry out press molding and injection molding in parallel.

[0039] Meanwhile, the injection molded part (200) includes a development section (210) that enters the baby's mouth and performs a development function, and a skin section (220) that protrudes from the lower part of the development section (210) at intervals in the circumferential direction and is joined to the joining section (130) to be integrated therewith.

[0040] At this time, the growing portion (210) has a shape of banana peels interlocked together, and a number of first growing projections (212) are protruded from a part of the periphery.

[0041] Also, a design portion (214) is formed around the development portion (210) and expresses various forms, shapes, and shapes that the baby can see and react to.

[0042] Here, the first developmental protrusion (212) is placed in the baby's mouth and rolled around, touched with the tongue, rubbed against the gums, and bitten with the gums, thereby inducing not only tactile play but also developmental functions.

[0043] It is preferable that the design unit (214) is configured to convey a sense of beauty, particularly to express characters that 0-1 year old babies like, so that babies can visually respond to them.

[0044] Moreover, the peel portion (220) represents the shape of a peeled banana, and it is preferable that at least three peel portions (220) are constituted.

[0045] The purpose of this skin part (220) is to improve the aesthetics by making it closer to the real shape, but its main function is to prevent a baby from putting the development part (210) too deep into his / her mouth, thereby preventing a safety accident.

[0046] However, since the leather part (220) has a shape and form that allows the baby to easily grasp or bite it, a number of secondary developmental projections (222) may be formed on the surface of the leather part (220).

[0047] In this case, the first and second developmental projections (212, 222) may have various shapes, but a line type with a certain interval between them is preferable.

[0048] The tooth development device according to the present invention having the above structure is manufactured in the following manner.

[0049] The method for manufacturing a tooth development device according to the present invention includes the steps of: preparing a mold for press molding; placing solid-phase silicon on the prepared press mold and press molding to form a press-molded part; preparing a mold for injection molding; demolding the press-molded part, fitting and fixing it in a prepared injection mold, closing the injection mold, and injecting injection liquid while performing injection molding to form an injection-molded part; and inspecting the quality after demolding when molding is complete.

[0050] At this time, the press molding die preparation process includes, as illustrated in Figures 5 and 6, a first process of providing a cavity in the shape of a support portion (110) and a lower half pin (12) for forming a position fixing hole (112) in the press lower die (10); a second process of providing a cavity in the shape of a pillar portion (120) in the press side die (20) and an upper half pin (22) that matches the lower half pin (12) on the lower surface of the cavity; and a third process of providing a cavity in the shape of a joint portion (130) having an injection groove (132) and a dam (134) on the lower surface of the press upper die (30).

[0051] The press side die (20) is a kind of slide die.

[0052] In addition, the process of making the press-molded part is a process in which, when the press upper die (30) is pressed, the solid-phase silicon contained therein enters the internal cavity of the press die and is molded into a shape that matches the shape of the cavity.

[0053] Furthermore, the injection molding mold preparation process includes, as illustrated in Figures 7 and 8, a fourth step of providing a fixing pin (42) in the lower injection mold (40) to be fitted into the position fixing hole (112); a fifth step of providing a cavity in the shape of a skin portion (220) in the upper part of the injection side mold (50); and a sixth step of forming a cavity in the shape of a teeth portion (210) in the upper injection mold (60) and an injection port (62) connected to this cavity.

[0054] When the press-molded part (100) is fixed to the lower injection mold (40), it is preferable to assemble the part so that the position fixing hole (112) is sandwiched by the fixing pin (42) and firmly fixed.

[0055] By carrying out press molding and injection molding in this order, the injected liquid enters the injection groove (132) and is trapped inside the dam (134) while hardening safely during bonding, making it possible to bond with a clean parting line.

[0056] In particular, since the injection liquid is liquid, it is easy to color the material and realize a desired color, which is advantageous in that different color tooth development devices can be molded with great freedom.

[0057] As described above, the present invention accurately realizes the shape of a peeled banana, enhancing aesthetics, while the banana peel acts as a stopper to prevent the banana from going too deep into the baby's mouth, preventing safety accidents. Furthermore, it is easy to mold, and instead of painting to create a color, different colors can be embodied at the same time as molding, further enhancing aesthetics. In addition, it is not harmful to the human body, has excellent bonding properties at the parts embodied in different colors, and does not cause interfacial separation even during heat sterilization, achieving a long life.
