Description

Technical Field

[0001] This application relates to the field of infant and toddler products technology, and in particular to a water-fillable rattle teether. Background Technology

[0002] Teething is a crucial period in an infant's growth and development. According to relevant medical research, approximately 80% of infants begin teething between 4 and 10 months of age. During this stage, babies experience significant discomfort in their gums and often relieve it by chewing on objects. Teething toys, as common supplementary products, effectively meet a baby's chewing needs and help soothe gum pain. Meanwhile, rattles and other rattle-like toys, with their sounds and colors, can stimulate a baby's hearing and vision, promoting sensory development.

[0003] However, current teething toys and rattles on the market have relatively limited functions. Traditional teething toys only have a single chewing function, failing to provide babies with more sensory stimulation; ordinary rattles focus on sound and visual attraction, lacking chewing and care functions, and cannot simultaneously meet babies' needs for chewing, sensory stimulation, and diverse tactile experiences. Furthermore, most teething toys cannot be filled with water, failing to provide babies with different temperature sensations and thus hindering their ability to effectively relieve gum discomfort. For example, when a baby's gums are swollen and painful, ordinary teething toys cannot provide supplementary relief through temperature changes. In addition, the shape of the teething parts in existing products is fixed, making it impossible to change them according to the baby's needs at different stages, resulting in poor flexibility. As babies' teething progresses, the required shape and hardness of the teething toy change at different stages, and a fixed-shape teething toy cannot continuously meet the baby's needs. Therefore, this invention proposes a water-fillable rattle teething toy to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a water-fillable rattle teether. By deeply integrating the functions of a rattle and a teether, it innovatively designs a replaceable teether replacement part and a water-fillable structure to precisely meet the usage needs of infants at different stages of teething, bringing a diverse user experience to babies. It not only effectively relieves teething discomfort but also promotes the baby's sensory development through sound, touch, and other stimuli, while improving the product's practicality and lifespan. The product includes a handheld component and a detachable teether part connected within the handheld component. The teether part is functionally divided into two replaceable replacement parts: Part 1 and Part 2. The handheld component has a slot for installing the teether part, and the teether part has a water-filling chamber. One end of the teether part has a handle, and the inner side of the handle has a water-filling hole. A sealing plug that matches the water-filling hole is fixed inside the handle via a connecting arc arm.

[0005] The teething component has a second positioning hole in the middle, and a sound generator is detachably connected inside the second positioning hole. The handheld component also has a first positioning hole, and the sound generator is snapped into the first positioning hole.

[0006] Furthermore, the handheld component has symmetrical handholds on both sides, and each handhold is fixed with an anti-slip rubber sleeve.

[0007] Furthermore, the sound generator includes two sets of symmetrically arranged hemispherical shells, which are fastened together by a snap-fit ​​groove, and the space between the two sets of hemispherical shells is filled with sound-emitting beads.

[0008] Furthermore, a second snap-fit ​​groove is provided between the two sets of hemispherical shells. The second snap-fit ​​groove is located on the outer circumference of the first snap-fit ​​groove, and a T-shaped rubber ring that mates with the second snap-fit ​​groove is fixed in the second positioning hole.

[0009] Furthermore, the replacement part one has a teething part one at the end away from the handle, and the teething part one is Y-shaped. The replacement part two has a teething part two at the end away from the handle, and the teething part two is semi-circular. Both teething parts one and teething parts two have raised textures to enhance the tactile feel.

[0010] Furthermore, the teething component has symmetrically fixed arc-shaped positioning protrusions on both sides of the middle part, and the arc-shaped positioning protrusions are provided with anti-slip protrusions. The inner wall of the insertion groove is symmetrically provided with arc-shaped positioning grooves that cooperate with the arc-shaped positioning protrusions.

[0011] The inner sides of both ends of the insertion slot are also provided with anti-detachment protrusions.

[0012] Furthermore, on the opposite side of the two sets of positioning holes, there is also a second anti-detachment protrusion for limiting the position of the sound generator.

[0013] Compared to existing technologies, the advantages of this application are:

[0014] This application deeply integrates the functions of a rattle and a teething toy. While babies relieve teething discomfort by chewing on the teething toy, the teething toy features two replaceable parts. The different shapes and textures of the teething toy can precisely adapt to the chewing needs of babies at different stages, satisfying their need for large-area chewing. This greatly improves the product's flexibility and applicability, and extends its lifespan. The water-filling chamber design of the teething toy allows for the filling of warm or cold water, providing babies with different temperature tactile experiences. At the same time, the water-filling design enhances the overall elasticity of the teething toy, increasing the gum stimulation effect. The water-filled teething toy also increases the overall weight, serving the purpose of exercising the baby's hand strength. With multiple functions, it has market potential.

[0026] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0027] Example 1:

[0028] This invention provides a water-fillable rattle teether; please refer to [link / reference]. Figures 1-9The core structure includes a handheld component 1 and a teething toy 2 detachably connected within the handheld component 1. The teething toy 2 is functionally designed as two replaceable parts: a first part 21 and a second part 22. This design fully considers the changing chewing preferences and needs of babies at different teething stages. The handheld component 1 has a groove 13 for fitting the teething toy 2, the shape of which ensures the teething toy 2 is securely installed and easily disassembled. The teething toy 2 has a water-filling cavity 207, which uses a one-piece injection molding design to ensure no leakage after water is filled. One end of the teething toy 2 has a handle 203, and the inner side of the handle 203 has a water-filling hole 204. A sealing plug 202, which mates with the water inlet 204, is fixed inside the handle 203 via a connecting arc arm 205. The sealing plug 202 is made of food-grade silicone, which has good elasticity and sealing properties, ensuring that there will be no leakage after water is filled. The teething toy 2 has a positioning hole 208 in the middle, which facilitates the installation and removal of the sound generator 3. The sound generator 3 is detachably connected inside the positioning hole 208. The handheld part 1 also has a positioning hole 12 that matches the sound generator 3. The sound generator 3 is snapped into the positioning hole 12, achieving a stable connection between the sound generator 3, the handheld part 1, and the teething toy 2.

[0029] Please refer to this first. Figure 2 The handheld part 1 has symmetrically designed ergonomic handholds 11 on both sides, with a smooth shape and size designed to accommodate the gripping habits of parents and babies. Each handhold 11 is fixed with an anti-slip rubber sleeve 111, which is made of environmentally friendly and non-toxic soft silicone material. The surface is designed with fine anti-slip texture, which greatly increases friction, making it easy for parents or babies to grip and preventing slippage. Even if the baby's hands are sweaty, they can still grip it easily.

[0030] Please refer to this first. Figures 6-8 The sound generator 3 includes two symmetrically arranged hemispherical shells 31. Both hemispherical shells 31 are made of high-strength and environmentally friendly plastic, possessing good toughness and durability. The two hemispherical shells 31 are precisely fastened together by a snap-fit ​​groove 311. The structural design of the snap-fit ​​groove 311 has been optimized multiple times, ensuring a tight and secure fit that is not easily loosened. A sound-emitting bead 32 is also filled between the two hemispherical shells 31. The sound-emitting bead 32 is made of a special material; when shaken, it collidees with the hemispherical shells 31 to produce a crisp, pleasant sound with a moderate volume, attracting the baby's attention without damaging their hearing.

[0031] A second locking groove 312 is provided between the two sets of hemispherical shells 31. The second locking groove 312 is located on the outer circumference of the first locking groove 311, which serves a double fixing function. A T-shaped rubber ring 206 that matches the second locking groove 312 is fixed in the second positioning hole 208. The T-shaped rubber ring 206 is made of high elastic silicone material. Its shape and size are adapted to the second locking groove 312 to ensure that the sound generator 3 is firmly installed on the teething toy 2 and will not easily fall off even if the baby shakes it vigorously.

[0032] Please refer to this first. Figures 3-4 Replacement part 1 21 has a teething part 211 at the end furthest from the handle 203. Teething part 211 is Y-shaped, a unique design that better meets the baby's need to chew on different edges. Its length, width, and curvature are all designed to conform to the baby's oral structure and chewing habits. Replacement part 22 has a teething part 221 at the end furthest from the handle 203. Teething part 221 is semi-circular, suitable for the baby to chew on a large area. Both teething parts 211 and 221 feature carefully designed raised textures to enhance tactile feedback. The shape, size, and spacing of these textures have been tested and optimized multiple times to effectively massage the gums without harming the baby's delicate mouth.

[0033] The teething component 2 has symmetrically fixed arc-shaped positioning protrusions 201 on both sides of its middle section. The arc-shaped positioning protrusions 201 are provided with anti-slip protrusions, and the surface of the anti-slip protrusions is frosted to further increase friction. The inner wall of the insertion groove 13 is symmetrically provided with arc-shaped positioning grooves 132 that cooperate with the arc-shaped positioning protrusions 201. The depth and curvature of the arc-shaped positioning grooves 132 are precisely matched with the arc-shaped positioning protrusions 201 to ensure that the teething component 2 and the handheld component 1 are installed firmly. The inner sides of both ends of the insertion groove 13 are also provided with anti-detachment protrusions 131. The height and width of the anti-detachment protrusions 131 are reasonably designed to effectively prevent the teething component 2 from accidentally detaching from the insertion groove 13.

[0034] Please see Figures 7-9 On one side opposite to the two sets of positioning holes 12, there is also an anti-detachment protrusion 121 for limiting the position of the sound generator 3. The shape and position of the anti-detachment protrusion 121 are precisely designed to match the structure of the sound generator 3, further ensuring the stability of the sound generator 3 after installation and preventing the sound generator 3 from shifting or falling off during use.

[0035] Before use, parents should choose the appropriate replacement part 1 (21) or replacement part 2 (22) based on the baby's current teething stage and biting preferences. If the baby is in the early stages of teething, with itchy gums concentrated in a localized area and a preference for biting different edges, the Y-shaped replacement part 1 (211) can be chosen. After installing replacement part 1 (211) onto the teether part 2, guide the baby to bite on it. The Y-shaped teether part 1 (211) can precisely stimulate the baby's gums and relieve discomfort. If the baby's teeth have partially erupted and require a larger area of ​​gum massage, and the baby prefers to bite on a larger area, then the semi-circular replacement part 2 (221) can be used. During the biting process, the raised textures on teether part 1 (211) and teether part 2 (221) will fully contact the baby's gums, effectively massaging the gums and promoting healthy tooth growth.

[0036] Rattle Usage: Parents or babies hold the handle 11 of the handpiece 1 and shake the product naturally by swinging their arm or shaking it up and down. The sound-producing beads 32 inside the sound generator 3 will collide with the hemispherical shell 31 under inertia, producing a crisp sound. When the baby is playing, crying, or has difficulty concentrating, the sound produced by shaking the product can attract the baby's attention and stimulate the baby's auditory development. For example, when the baby is playing in bed, the parent can shake the product, and the sound can guide the baby to find the sound source, exercising the baby's hearing and reaction ability.

[0037] Water Injection Usage: Before injecting water, ensure the product is clean. Open the sealing plug 202 of the water injection hole 204 inside the handle 203. Using a clean syringe or other suitable water injection tool, draw an appropriate amount of warm or cold water. The recommended water temperature is between 30-40℃. The cold water temperature should not be too low to avoid irritating the baby's gums. Align the water injection nozzle of the water injection tool with the water injection hole 204 and slowly inject the liquid. Observe the water level in the water injection chamber 207 carefully to avoid overfilling and causing overflow. After injecting water, promptly and tightly close the sealing plug 202 to ensure a good seal and prevent leakage. At this time, when the baby chews on the teething toy 2, they can feel the different temperatures, further relieving gum discomfort. For example, when the baby's gums are red and swollen, injecting cold water can help reduce swelling; injecting warm water can bring a warm and comfortable feeling, soothing the baby's emotions.

[0038] Simultaneously, water is injected into the water-filled cavity 207, which can effectively improve the overall elasticity of the teething component 2, providing a certain resistance for the baby to bite and further enhancing the gum exercise effect.

[0039] Clean the product promptly after each use. Prepare a basin of warm water, add an appropriate amount of baby-specific cleaning agent, and stir well. Place the handheld part 1, teething toy part 2, and sound generator 3 into the water and gently scrub with a soft brush, paying special attention to cleaning the teething part 2, the water inlet 204, and the crevices of the sound generator 3—areas prone to dirt accumulation. After cleaning, rinse thoroughly with clean water to remove any cleaning agent residue. Then, dry with a clean, soft towel and place in a well-ventilated, dry place to air dry naturally, avoiding direct sunlight to prevent product aging.

[0040] Regularly check the connections of all parts of the product; it is recommended to check at least once a week. Check whether the connection between the teething part 2 and the handheld part 1 is secure by gently shaking the teething part.

[0041] This application deeply integrates the functions of a rattle and a teething toy. While the baby relieves teething discomfort by chewing on the teething toy, the sound emitted by the sound generator 3 when the product is shaken stimulates the baby's auditory development and attracts their attention. It realizes a transformation from a single function to multi-dimensional care and entertainment, promoting the baby's all-round sensory development.

[0042] Teether part 2 is equipped with replaceable replacement part 1 21 and replacement part 2 22. Teether parts with different shapes and textures can accurately adapt to the chewing needs of babies at different stages, meet the needs of babies to chew on a large area, greatly improve the flexibility and applicability of product use, and extend the product's service life.

[0043] The teething toy 2 features a water-filling chamber 207 that can be filled with warm or cold water, providing babies with different temperature tactile experiences. The water-filling design also enhances the overall elasticity of the teething toy 2, increasing the stimulation effect on the gums. Furthermore, the water-filled teething toy 2 increases its overall weight, which helps to strengthen the baby's hand muscles. With its diverse functions, it has promising market prospects.

[0044] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
