Teeth grower

The present invention relates to a teether, and more specifically, to an improved teether which accurately embodies the shape of a peeled banana to enhance aesthetics, and in which the banana peel portion functions as a stopper to prevent safety accidents by preventing the product from entering deep into a baby's mouth, and which is easy to mold and allows for a different color to be implemented simultaneously with molding instead of being painted to provide color, thereby further enhancing aesthetics, causes no harm to the human body, and has excellent bonding properties in the part implemented as a different color, so that interface separation does not occur even during heat sterilization, thereby achieving a long lifespan.

Babies begin to explore with their hands around 3 months of age, and their first teeth begin to grow around 6 months of age, which is when they experience teething pain.

When teething begins, teeth may start to come out through holes, causing tickling or pain, and the child may become sensitive. Babies aged 14 to 16 months, especially, experience severe symptoms when their first molars come out, and symptoms usually last for about 3 days.

During this process, teething devices (aka 'teething devices') are often used to help oral development by stimulating the gums, relieve tickling, and develop fine motor skills by starting hand grasping practice.

The most commonly used teether is a wrist teether, which is mostly a round, circular shape that can be held by hand and bitten with the mouth, as disclosed in the [prior art literature] below.

In addition, there are those shaped like plants or fruits, and they are made of silicone, which is harmless to the human body and has excellent heat resistance.

In particular, among the fruit-shaped teethers, the banana shape is popular. The banana shape is the most suitable size for babies to hold with one hand, and the addition of protrusions to the peel can help develop babies' dental sense.

In addition, the banana leaf part acts as a safety measure to prevent the product from going too deep into the baby's mouth, the bottom part has more protrusions to increase baby's dental sensitivity, and the geometric holes help develop baby's senses.

However, as in the example of Fig. 1, in the case of banana leaves, the mold design is difficult, so the aesthetic is not good and it does not look natural, as if the banana peel was just peeled off.

That is, due to the design of the mold, it is difficult to implement the ends of the banana peel to be rounded and bent downward, so as in the example, they are all lifted upward, making it easy for the slide mold to fall out. In addition, there is a limitation that the peels can only be implemented in even numbers, such as 2 or 4, which is unnatural.

In addition, since it is formed by pressing and stamping high-performance silicone, the upper part of the shell shape and the lower part including the shell are formed in two parts and then heat is applied to bond them together, making the work complex and requiring post-processing due to the occurrence of burrs on the bonding surface.

In addition, since it is molded by pressing high-performance silicone, it is difficult to implement various colors as a different color, so it is mostly released in a single color, or if the color is implemented differently, it is created by painting the color through a separate process.

Therefore, if you have to paint it separately to get a different color, there is a risk of harmful substances being released into the child's mouth, and it is also unsanitary.

The present invention has been created to solve the above-described problems of the prior art, by accurately implementing the shape of a peeled banana to enhance aesthetics, and the banana peel portion functions as a stopper to prevent safety accidents by preventing the product from entering deep into a baby's mouth. In addition, the present invention provides an improved teething device that is easy to mold and can be implemented in a different color at the same time as molding rather than painting it to provide color, thereby further enhancing aesthetics, causing no harm to the human body, and having excellent bonding properties in the part implemented in a different color so that interface separation does not occur even during heat sterilization, thereby achieving a long lifespan.

The present invention provides a teething device, which comprises a press-molded part (100) having a shape that a baby can hold with his or her hand, and an injection-molded part (200) that is joined to the press-molded part (100) to form an integral part and enters the baby's mouth to provide a teething function.

At this time, the press-molded part (100) includes a support part (110), a pillar part (120) that is erected as an integral part with the support part (110), a joint part (130) formed at the upper end of the pillar part (120) and to which the injection-molded part (200) is joined; the injection-molded part (200) is also characterized in that it includes a teething part (210) that enters a baby's mouth and performs a teething function, and a shell part (220) that protrudes circumferentially from the lower end of the teething part (210) at intervals and is joined to the joint part (130) to form an integral part.

In addition, the support part (110) includes a plurality of position fixing holes (112); the joint part (130) includes an injection groove (132) into which a liquid can be injected, and a dam (134) formed in the shape of a jaw along the circumference of the injection groove (132); the injection molding part (200) includes a teething part (210) that enters a baby's mouth and performs a teething function, and a shell part (220) that protrudes circumferentially from the lower end of the teething part (210) at intervals and is joined to the joint part (130) to form an integral body; Another feature is that a number of first tooth protrusions (212) protrude from some portion of the circumference of the above-mentioned tooth portion (210), a design portion (214) is formed on another portion of the circumference of the above-mentioned tooth portion (210), and a number of second tooth protrusions (222) are formed on the surface of the shell portion (220).

According to the present invention, the following effects can be obtained.

First, the shape of the peeled banana can be accurately implemented to make it as realistic as possible.

Second, the banana peel acts as a stopper, preventing accidents by preventing the banana from going deep into the baby's mouth.

Third, by using a press mold and an injection mold in parallel to combine press molding and injection molding, there is an advantage in that the degree of freedom in molding is increased, making molding easier.

Fourth, since it is possible to implement a different color at the same time as molding, there is no need to paint it separately.

Fifth, the fixing strength at the joint is excellent, so that interface separation does not occur even during heat sterilization, allowing for a long service life.

Sixth, it is harmless to the human body.

Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the attached drawings.

Before describing the present invention, the following specific structural and functional descriptions are merely exemplified for the purpose of explaining embodiments according to the concept of the present invention, and the embodiments according to the concept of the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described in this specification.

In addition, since the embodiments according to the concept of the present invention can have various changes and can have various forms, specific embodiments are illustrated in the drawings and described in detail in the present specification. However, this is not intended to limit the embodiments according to the concept of the present invention to a specific disclosed form, but should be understood to include all modifications, equivalents, or substitutes included in the spirit and technical scope of the present invention.

As shown in FIGS. 2 and 3, the teething device according to the present invention includes a press-molded part (100) in the shape of a banana that a baby can hold with his or her hand, and an injection-molded part (200) that is joined to the press-molded part (100) to form an integral part and enters the baby's mouth to provide a teething function.

That is, unlike the conventional method of producing a tooth growth device only through press molding, the tooth growth device according to the present invention is manufactured in a new form that combines press molding and injection molding, thereby improving moldability and facilitating mold design, allowing free curve expression, and thereby implementing it as close to a real banana as possible.

Therefore, the present invention enables expression of three shells, and also enables expression of a shell in a shape that is rounded downward, thereby enhancing aesthetics. Above all, since injection molding uses liquid silicone, it is easy to implement colors, allowing free two-color molding, and thus has the advantage of being able to implement various desired colors without having to paint separately as before.

In addition, the press-molded part (100) includes a support part (110), a pillar part (120) that is erected integrally with the support part (110), and a joint part (130) formed at the upper end of the pillar part (120) and to which the injection-molded part (200) is joined.

At this time, the support part (110) has a circular shape with a number of arc shapes, for example, a flower petal shape, and is processed into a round shape so that babies can feel the touch, and has a structure in which a number of position-fixing holes (112) are formed.

Here, the position fixing hole (112) is not only an important element that precisely matches the parting surface with the press molding part (100) during injection molding to prevent a bonding defect, but also contributes to the development of fine muscles when babies hold it with their hands or play with their fingers, and helps with oral development through gum stimulation when biting it with their mouths, and also helps relieve ticklishness.

In addition, the pillar part (120) is the main part that babies grasp with their hands, and is a means to guide them to conveniently perform such actions, such as repeatedly grabbing and putting down a jam jam, as well as biting and pulling the teething part (210) with their mouth and chewing.

In addition, the above joint (130) is implemented as is in the shape of a banana peel when peeled, as in the examples of FIGS. 2 and 4, and includes an injection groove (132) into which injection liquid can be injected, and a dam (134) formed in the shape of a chin along the periphery of the injection groove (132) to prevent the injected injection liquid from overflowing or forming a burr along the interface.

Therefore, when the injection mold is closed, an accurate parting line is formed, which prevents burr generation, prevents misalignment of the parting surface, and induces uniform and accurate joining.

That is, since this concept did not exist in the past, only press molding could be used, and only a technology for bonding the teeth with heat after press molding could be implemented. However, in the present invention, by implementing the above-described configurations, press molding and injection molding can now be performed in parallel.

Meanwhile, the injection molded part (200) includes a teething part (210) that enters the baby's mouth and performs a teething function, and a shell part (220) that protrudes circumferentially from the lower end of the teething part (210) at intervals and is joined to the joining part (130) to form an integral body.

At this time, the tooth protrusion (210) has a shape of a peeled banana, and a number of first tooth protrusions (212) protrude from some of the circumference.

In addition, a design section (214) expressing various shapes, figures, and figures that babies can see and react to is formed on another part of the perimeter of the teething section (210).

Here, the first teething protrusion (212) is used to induce tactile play as well as teething function by babies putting it in their mouths and rolling it, touching it with their tongues, rubbing their gums, or biting it with their gums.

In addition, it is desirable to configure the design section (214) so that it can convey aesthetics, especially by expressing characters that babies aged 0-1 like, so that babies can visually react to them.

In addition, the peel part (220) expresses the shape of a peeled banana, and it is preferable to configure at least three peel parts (220).

Although the purpose of this shell part (220) is to improve the aesthetics by making it look more realistic, its main function is to prevent safety accidents by preventing the baby from putting the teething part (210) deep into the mouth.

However, since the shell part (220) has a shape and form that babies can easily grasp or chew, a number of second teething protrusions (222) can be formed on the surface of the shell part (220).

In this case, the first and second tooth protrusions (212, 222) may have various shapes, but a line type with a certain interval is preferable.

A teething device according to the present invention having such a configuration is manufactured by the following method.

The method for manufacturing a teething device according to the present invention comprises a step of preparing a press mold for press molding, a step of placing solid silicone on the prepared press mold and performing press molding to create a press molded part; a step of preparing an injection mold for injection molding; a step of demolding the press molded part, fixing it in the prepared injection mold, closing the injection mold, and injecting an injection fluid while performing injection molding to create an injection molded part; and a step of inspecting the quality after demolding when molding is complete.

At this time, the press forming mold preparation step includes, as in the examples of FIGS. 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 a press lower mold (10); a second process of providing a cavity in the shape of a pillar portion (120) in a press side mold (20) and an upper half pin (22) that is fit together with 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 a press upper mold (30).

And, the above press side mold (20) is a type of slide mold.

In addition, the step of making the press-molding part is a step in which, when the press upper mold (30) is pressed, the solid silicon contained therein enters the internal cavities of the press mold and is formed into a shape that fits the shape of the cavity.

In addition, the injection molding mold preparation step includes, as in the examples of FIGS. 7 and 8, a fourth step of providing a fixing pin (42) to be fitted into the position fixing hole (112) in the injection lower mold (40); a fifth step of providing a cavity in the shape of a shell part (220) in the upper part of the injection side mold (50); and a sixth step of forming a cavity in the shape of a tooth part (210) in the injection upper mold (60) and an injection port (62) connected to the cavity.

And, when fixing the press-molding part (100) to the injection lower mold (40), it is desirable to assemble it so that the position fixing hole (112) is firmly fixed by being fitted into the fixing pin (42).

By sequentially performing press molding and injection molding in this manner, the injection liquid enters the injection groove (132) and is safely hardened and bonded while being trapped in the dam (134), making it possible to form a bond with a clean parting line.

In particular, since the injection solution is liquid, it is easy to colorize, making it easy to implement the desired color, and this has the advantage of allowing very free molding of teeth development devices in different colors.

As described above, the present invention accurately implements the shape of a peeled banana, thereby enhancing aesthetics, and the banana peel portion functions as a stopper to prevent safety accidents by preventing the product from entering deep into a baby's mouth, and is easy to mold, and instead of painting on the color, a different color can be implemented simultaneously with the molding, thereby further enhancing aesthetics, causing no harm to the human body, and since the bonding properties in the part implemented as a different color are excellent, no interface separation occurs even during heat sterilization, thereby achieving a long lifespan.
