Description

Technical Field

[0001] This utility model relates to the field of swimming ring technology, and more specifically, to a thermoformed pearl cotton baby neck swimming ring. Background Technology

[0002] An infant neck float, also known as an infant swimming ring, is a special neck ring for infants that is usually placed around their necks to allow them to float on the water. The neck ring has an opening at the end for easy access for the baby's head. To use it, simply inflate the neck ring, then open it from the opening and place it around the baby's neck, and then fasten the buckle at the opening. The baby will then float on the water surface due to the buoyancy of the air inside the neck ring.

[0003] Existing inflatable baby neck floats are prone to rupture and air leakage when exposed to sharp objects, posing a safety hazard. In addition, some existing baby neck floats are prone to tipping over during use due to the baby's movements or encountering waves, which is not very safe. Furthermore, when in use, the opening is prone to misalignment when exposed to water waves or other external forces, which can cause the neck float to deform and the neck opening to contract and compress the baby's trachea or carotid artery, making it unsafe to use. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a thermoformed pearl cotton baby neck float ring, comprising a body, a neck hole provided vertically on the body, an opening communicating with the neck hole on the body, the body comprising a first pearl cotton layer, a second pearl cotton layer, and a third pearl cotton layer, the first pearl cotton layer being connected to the lower side of the second pearl cotton layer, the third pearl cotton layer being connected to the upper side of the second pearl cotton layer, the density of the first pearl cotton layer, the second pearl cotton layer, and the third pearl cotton layer decreasing sequentially, and a first pearl cotton layer being provided on the upper side of the body. The main body has a second groove on its lower side. One end of the neck loop extends to the concave surface of the first groove, and the other end extends to the concave surface of the second groove. The vertical height of the neck loop is less than the vertical height of the main body. This utility model features a thermoformed pearl cotton baby neck float ring. The lower layer of pearl cotton near the water surface has a higher density, providing stronger support and preventing tipping. This ensures the baby's head is always above the water surface, preventing choking. The upper layer has a lower density, conforming to the baby's chin and neck, reducing pressure, while allowing slight neck movement to avoid stiffness. It is comfortable and safe to use.

[0005] Optionally, both the first groove and the second groove are arc-shaped grooves, and both the first groove and the second groove are formed by a hot-melt process.

[0006] Optionally, the first pearl cotton layer and the second pearl cotton layer are heat-fused together, and the second pearl cotton layer and the third pearl cotton layer are heat-fused together.

[0007] Optionally, the density difference between adjacent layers of the first pearl cotton layer, the second pearl cotton layer, and the third pearl cotton layer is 5 kg / m³ to 20 kg / m³.

[0008] Optionally, one end of the neck hole extends to the center of the concave surface of the first groove, and the other end of the neck hole extends to the center of the concave surface of the second groove. An arc-shaped portion is provided at the connection between the neck hole and the first groove.

[0009] Optionally, the main body is provided with a placement slot for placing the baby's chin.

[0010] Optionally, the opening divides the body into a first block and a second block. The first block has a positioning protrusion on the side near the second block, and the second block has a positioning groove corresponding to the positioning protrusion. In use, the positioning protrusion falls into the positioning groove for positioning.

[0011] Optionally, the positioning protrusion includes a first positioning protrusion and a second positioning protrusion, and the positioning groove includes a first positioning groove corresponding to the first positioning protrusion and a second positioning groove corresponding to the first positioning protrusion.

[0012] Optionally, the first block is provided with a first connector and a second connector, and the second block is provided with a third connector and a fourth connector. The first connector and the third connector are detachably connected, and the second connector and the fourth connector are detachably connected.

[0013] Optionally, the first connector is a first female snap fastener, the second connector is a second female snap fastener, the third connector is a first male snap fastener, and the fourth connector is a second male snap fastener. A first rope is connected between the first connector and the first block, with one end of the first rope connected to the first connector and the other end connected to one side of the first positioning protrusion. A second rope is connected between the second connector and the first block, with one end of the second rope connected to the second connector and the other end connected to one side of the second positioning protrusion.

A fourth rope is connected between the fourth connector and the second block, with one end of the fourth rope connected to the fourth connector and the other end connected to one side of the second positioning groove.

[0014] Compared to existing technologies, this novel thermoformed pearl cotton baby neck float features a lower layer of pearl cotton with a higher density near the water surface, providing stronger support and preventing tipping. This ensures the baby's head remains above the water, preventing choking. The upper layer has a lower density, conforming to the baby's chin and neck to reduce pressure while allowing slight neck movement to prevent stiffness, resulting in comfortable and safe use. Both the first and second grooves are curved, providing a smooth transition and a softer feel. Both grooves are formed using a thermoforming process, and the different densities of the pearl cotton layers are heat-fused to avoid delamination during processing. The first and second pearl cotton layers are thermoformed together, as are the second and third layers. The different densities are also bonded together using thermoforming, ensuring a strong bond and minimizing the risk of delamination. Attached Figure Description

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0024] Example 1:

[0025] See Figures 1-4 Embodiment 1 of this utility model provides a thermoformed pearl cotton baby neck float, including a body 1. A neck hole 101 is vertically arranged on the body 1, and an opening 102 communicating with the neck hole 101 is also provided on the body 1. The body 1 includes a first pearl cotton layer 11, a second pearl cotton layer 12, and a third pearl cotton layer 13. The first pearl cotton layer 11 is connected to the lower side of the second pearl cotton layer 12, and the third pearl cotton layer 13 is connected to the upper side of the second pearl cotton layer 12. The density of the first pearl cotton layer 11, the second pearl cotton layer 12, and the third pearl cotton layer 13 decreases sequentially. A first groove 10 is provided on the upper side of the body 1. 3. A second groove 104 is provided on the lower side of the main body 1. One end of the neck hole 101 extends to the concave surface of the first groove 103, and the other end of the neck hole 101 extends to the concave surface of the second groove 104. The vertical height of the neck hole 101 is less than the vertical height of the main body 1. The thermoformed pearl cotton baby neck float of this utility model has a higher density of pearl cotton in the lower layer near the water surface, which provides stronger support and is less likely to tip over, ensuring that the baby's head is always above the water surface and preventing choking. The upper layer has a lower density, fits the baby's chin and neck, reduces pressure, and allows slight neck movement to avoid stiffness, making it comfortable and safe to use.

[0026] Specifically, because the density of pearl cotton is less than that of water, it can float on the water surface without inflation, providing buoyancy for the baby and avoiding the problem of air leakage associated with inflation. In this embodiment, the density of the pearl cotton layers gradually increases from bottom to top, achieving a progressive buoyancy distribution. The lower layer of pearl cotton, closer to the water surface, has a higher density (greater hardness), providing stronger support and ensuring that the baby's head is always above the water surface to prevent choking. The high-density layer acts like a "base," lowering the center of gravity and suppressing the risk of tipping over, maintaining balance even when the baby is moving. The upper layer has a lower density (softer), conforming to the baby's chin and neck to reduce pressure while allowing slight neck movement to avoid stiffness. The low-density layer absorbs the energy from water ripples. This design reduces the impact on the neck from sudden movements, providing a shock-absorbing effect. The multi-layered structure also allows for adjustment of the thickness of each layer to accommodate the different neck development differences of infants at different ages. For example, for younger infants who are lighter and have more delicate tissues, the thickness of the top layer is increased to ensure softness and comfort during use. For older infants who are heavier, the thickness of the bottom layer is increased to ensure sufficient stability. The first groove 103 and the second groove 104 are provided to reduce the vertical height of the neck loop 101, preventing the neck loop 101 from being too high due to the three-layer pearl cotton structure, thus avoiding the problem of the neck loop 101 being too high and preventing the infant's neck from being unable to turn flexibly after being covered.

[0027] See Figure 1 and Figure 4 Both the first groove 103 and the second groove 104 are arc-shaped grooves with a smooth transition and a softer touch. Both the first groove 103 and the second groove 104 are formed by hot-melt process. The pearl cotton layers of different densities are processed by hot-melt to avoid the risk of delamination during the processing. The first pearl cotton layer 11 and the second pearl cotton layer 12 are hot-melt bonded together, and the second pearl cotton layer 12 and the third pearl cotton layer 13 are hot-melt bonded together. The pearl cotton layers of different densities are bonded together by hot-melt, which is a strong bond and is not prone to delamination (traditional adhesives are prone to failure due to water immersion).

[0028] See Figure 1 and Figure 4The density difference between adjacent layers of the first pearl cotton layer 11, the second pearl cotton layer 12, and the third pearl cotton layer 13 is 5 kg / m³-20 kg / m³ to avoid abrupt changes in rigidity that could reduce comfort. Specifically, in this embodiment, the density of the first pearl cotton layer 11 is 35 kg / m³, the density of the second pearl cotton layer 12 is 25 kg / m³, and the density of the third pearl cotton layer 13 is 18 kg / m³. In this embodiment, there are three pearl cotton layers, but more than three layers can be provided as needed. One end of the neck hole 101 extends to the center of the concave surface of the first groove 103, and the other end of the neck hole 101 extends to the center of the concave surface of the second groove 104, making the structural weight distribution uniform and preventing tipping. An arc-shaped part 105 is provided at the connection between the neck hole 101 and the first groove 103, which is soft to the touch and comfortable to use.

[0029] See Figure 1 and Figure 3 The main body 1 is provided with a placement groove 106 for the baby to place his / her chin, so as to stabilize the baby's head position. The placement groove 106 supports the chin and prevents the baby's head from tilting forward due to weak neck muscles, thus reducing the risk of accidental water immersion in the mouth and nose.

[0030] See Figures 1-3 The opening 102 divides the main body 1 into a first block 111 and a second block 112. A positioning protrusion 2 is provided on the side of the first block 111 near the second block 112, and a positioning groove 3 corresponding to the positioning protrusion 2 is provided on the second block 112. In use, the positioning protrusion 2 falls into the positioning groove 3 for positioning. The first block 111 and the second block 112 are less likely to be misaligned during use, thereby improving safety. The positioning protrusion 2 includes a first positioning protrusion 21 and a second positioning protrusion 22, and the positioning groove 3 includes a first positioning groove 31 corresponding to the first positioning protrusion 21 and a second positioning groove 32 corresponding to the first positioning protrusion 21. The positioning effect is good, further improving safety.

[0031] See Figures 1-3The first block 111 is provided with a first connector 41 and a second connector 42, and the second block 112 is provided with a third connector 43 and a fourth connector 44. The first connector 41 and the third connector 43 are detachably connected, and the second connector 42 and the fourth connector 44 are detachably connected. In use, the first connector 41 is connected to the third connector 43, and the second connector 42 is connected to the fourth connector 44. The multiple connectors prevent relative displacement between the first block 111 and the second block 112 during use, avoiding detachment, misalignment, etc., and ensuring reliable use. The first connector 41 is a first female buckle, the second connector 42 is a second female buckle, the third connector 43 is a first male buckle, and the fourth connector 44 is a second male buckle. A first rope 51 is connected between the first connector 41 and the first block 111. One end of the first rope 51 is connected to the first connector 41, and the other end of the first rope 51 is connected to the first positioning protrusion. On one side of 21; a second rope 52 is connected between the second connector 42 and the first block 111, one end of the second rope 52 is connected to the second connector 42, and the other end of the second rope 52 is connected to one side of the second positioning protrusion 22; a third rope 53 is connected between the third connector 43 and the second block 112, one end of the third rope 53 is connected to the third connector 43, and the other end of the third rope 53 is connected to one side of the first positioning groove 31; a fourth rope 54 is connected between the fourth connector 44 and the second block 112, one end of the fourth rope 54 is connected to the fourth connector 44, and the other end of the fourth rope 54 is connected to one side of the second positioning groove 32; the four connectors lock the first block 111 and the second block 112, making it difficult for relative displacement to occur; and the four connectors are located at the position where the positioning groove and the corresponding positioning protrusion engage, which can improve the stability of the engagement between the positioning groove and the corresponding positioning protrusion, and further improve the safety during use.

[0032] Example 2:

[0033] See Figure 5 The difference between this embodiment two and embodiment one is that: in this embodiment two, the pearl cotton layer has five layers. The lower side of the first pearl cotton layer 11 is heat-fused to the fourth pearl cotton layer 14, and the upper side of the third pearl cotton layer 13 is heat-fused to the fifth pearl cotton layer 15. The density of the fourth pearl cotton layer 14 is greater than that of the first pearl cotton layer 11, and the density of the fifth pearl cotton layer 15 is less than that of the third pearl cotton layer 13. The progressive buoyancy distribution has more layers. The lower pearl cotton layer near the water surface has a higher density (higher hardness) and provides stronger support to ensure that the baby's head is always above the water surface to prevent choking. The high-density layer acts like a "base" to lower the center of gravity and suppress the risk of tipping over, so that the baby can maintain balance even when moving. The upper layer has a lower density (softer) and fits the baby's chin and neck to reduce pressure, while allowing slight neck movement to avoid stiffness. The low-density layer absorbs the energy of water wave swaying and reduces the impact of sudden movements on the neck, thus playing a shock absorption role.

[0034] This utility model relates to a thermoformed pearl cotton baby neck float. The lower layer of pearl cotton, closer to the water surface, has a higher density, providing stronger support and preventing tipping. This ensures the baby's head remains above the water, preventing choking. The upper layer has a lower density, conforming to the baby's chin and neck to reduce pressure while allowing slight neck movement to avoid stiffness, resulting in comfortable and safe use. Both the first and second grooves are curved, with a smooth transition and a softer feel. Both grooves are formed using a thermoforming process, and the different densities of the pearl cotton layers are thermoformed together to avoid delamination during processing. The first and second pearl cotton layers are thermoformed together, as are the second and third pearl cotton layers. The different densities of the pearl cotton layers are also thermoformed together, ensuring a strong bond and minimizing the risk of delamination.
