Description

Technical Field

[0001] This utility model belongs to the field of neck ring technology and relates to a neck ring. Background Technology

[0002] Neck rings are a new type of product for cooling in summer and keeping warm in winter. Their principle is similar to that of hot water bottles. A flexible container is filled with a liquid with a high specific heat capacity, such as water. In summer, an appropriate amount of ice cubes are poured in and then cold water is poured in, or cold water is poured in and then placed in the refrigerator to cool it down before wearing it around the neck, so that people feel a cooling sensation. In winter, hot water is poured in, with the water temperature around 60℃, so that people feel warmer and can also play a role in neck care.

[0003] For example, a neck ring and its manufacturing method are disclosed in Chinese patent application (application number: 202410073080.7). The neck ring includes a cooling neck body, a first TPU membrane sleeve sealed to the outside of the cooling neck body, and a second TPU membrane sleeve sealed to the outside of the first TPU membrane sleeve. Hydrogel or PU gel is filled between the first and second TPU membrane sleeves. The neck ring body is made of phase change material PCM or composed of several hollow spheres filled with phase change material PCM. However, because both the first and second TPU membrane sleeves are flexible materials, they lack support and are easily deformed. When worn around the neck, the two ends of the neck ring naturally droop under gravity, causing the part of the neck ring that is in contact with the skin at the back of the neck to bend. This causes the neck ring on both sides of the neck to pull inwards and press tightly against the neck, resulting in excessive compression. Since the blood vessels and nerves on both sides of the neck are relatively dense, prolonged compression can easily cause discomfort. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a neck brace. The technical problem this invention aims to solve is: how to improve the wearing comfort of the neck brace.

[0005] The purpose of this utility model can be achieved through the following technical solution: a neck ring, characterized in that it includes two bladders made of flexible material and having cavities, and an inner connector and an outer connector made of rigid material. One end of each bladder has a tubular interface. The two ends of the inner connector are respectively inserted into the interfaces of the two bladders and fixedly connected to the interfaces. The outer connector covers the outside of the two interfaces and is fixedly connected to the two interfaces.

[0006] This invention employs a split-structure design, connecting two flexible pouches via an inner and outer connector made of rigid materials. The outer connector is located in the middle of the two pouches. When worn, the outer connector contacts and rests against the back of the neck. Because the outer and inner connectors are made of rigid materials, they provide a certain degree of rigidity, thus providing some outward expansion and support to the pouches on both sides. This prevents the pouches from excessively converging under gravity, maintaining contact between the pouches and the skin on both sides of the neck while avoiding excessive pressure on the neck, resulting in greater comfort. Furthermore, the connection between the two pouches via the outer and inner connectors ensures greater stability, preventing detachment and leakage.

[0007] In the aforementioned neck collar, both the inner and outer connectors are welded to the interface of the bladder body.

[0008] In the aforementioned neck collar, an annular groove is formed between the two bladders and the outer connector. An outer sleeve, made of a flexible material, is fitted inside the annular groove to cover the outer connector. The outer sleeve can be made of silicone, thus enhancing comfort through contact with the skin of the neck and back.

[0009] In the aforementioned neck collar, the inner connector includes plug-in portions located at both ends and an annular protrusion located between the two plug-in portions. The inner connector is inserted into the interface of the bladder through the plug-in portions, and the annular protrusion abuts against the outer end face of the interface, thereby ensuring proper installation.

[0010] In the aforementioned neck collar, the outer wall of the inner connector's insertion portion, the inner wall of the outer connector, and the inner and outer walls of the interface are all provided with several annular ribs arranged circumferentially and spaced apart along the length direction. This allows the inner and outer connectors to interlock with the interface of the bladder body, improving the stability and sealing of the connection.

[0011] In the aforementioned neck collar, the outer connector includes a first side cover and a second side cover. Both sides of the first side cover have outwardly protruding connecting protrusions, and both sides of the second side cover have connecting grooves for the connecting protrusions to be inserted. The outer connector adopts a two-part structure for easy installation.

[0012] In the aforementioned neck collar, the end of the bladder furthest from the connector has an inlet, and an annular connection port is fixed at the inlet. This connection port is made of a rigid material and has a sealing cap for sealing the inlet. Phase change materials or ice water, etc., can be filled into the bladder through the inlet. Furthermore, the rigid connection port and sealing cap at the inlet of the bladder make it less prone to deformation and provide better sealing.

[0013] In the aforementioned neck ring, a sealing ring is also provided at the inlet of the bladder body, surrounding the connection port, to further improve the sealing effect.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This utility model uses two sacs connected by an inner and outer connector made of rigid material, which provides support and sealing to both the inner and outer walls of the interface. The inner and outer connectors also provide some outward expansion and support to the two sacs on both sides, preventing excessive pressure on the sides of the neck when wearing the device and making the wearer more comfortable.

[0016] 2. The inner connector, outer connector, and the interface of the bladder are all equipped with intermittently spaced annular ribs. The interlocking of the annular ribs further improves the connection stability and sealing effect.

[0017] 3. The outer connector of this utility model adopts a split structure, which is convenient for installation and welding. In addition, the outer side of the outer connector is covered with a soft material jacket to avoid direct contact between the hard outer connector and the human body, further improving wearing comfort.

Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] A type of neck brace, such as Figure 1 , Figure 2As shown, it includes two elongated sacs 1 and an inner connector 2 and an outer connector 3 for connecting the two sacs 1. The sacs 1 are made of skin-friendly flexible materials such as flexible PVC, TPU or silicone. The sacs 1 are elongated and narrow at the top and wide at the bottom. The sacs 1 have a cavity 1a inside, which can be filled with water or other phase change materials for storing cold and providing a continuous cooling sensation when worn. The smaller cross-section end of each sac 1 is provided with a tubular interface 11, which communicates with the cavity 1a. The inner connector 2 and the outer connector 3 are both made of rigid PVC material. Of course, other rigid materials can also be used. The two ends of the inner connector 2 are inserted into the interfaces 11 of the two sacs 1 and fixed to the interfaces 11. At the same time, the outer connector 3 covers the interfaces 11 of the two sacs 1 and is fixed to the interfaces 11, so that the two sacs 1 are connected to form a whole. When worn, the inner connector 2 and the outer connector 3 provide certain support to the two sides of the bladder 1, preventing excessive deformation under the weight of the bladder 1 and thus avoiding excessive pressure on the wearer's neck, thereby providing the wearer with a better user experience.

[0027] Specifically, such as Figures 3-6 As shown, both the inner connector 2 and the outer connector 3 are hollow tubular, and the cross-sections of the inner connector 2, the interface 11 of the capsule 1, and the outer connector 3 are all arc-shaped, giving them high resistance to deformation. In this embodiment, the inner connector 2, the outer connector 3, and the interface 11 are all ultrasonically welded. The inner connector 2 includes insertion portions 21 located at both ends and an annular protrusion 22 located between the two insertion portions 21. When the insertion portions 21 at both ends of the inner connector 2 are inserted into the two interfaces 11, the annular protrusion 22 can abut against the end face of the interface 11, ensuring that the interface 11 and the inner connector 2 are connected in place. The outer wall of the insertion part 21 of the inner connector 2, the inner wall of the outer connector 3, and the inner and outer walls of the interface 11 are all provided with a number of annular ribs arranged circumferentially and spaced apart along the length direction. This interlocks the annular ribs on the outer wall of the inner connector 2 with the annular ribs on the inner wall of the interface 11, and the annular ribs on the outer wall of the interface 11 with the annular ribs on the inner wall of the outer connector 3. This increases the contact area during ultrasonic welding, improves the sealing performance, and enhances the structural strength, making it less prone to deformation.

[0028] Furthermore, for ease of installation, in this embodiment, the external connector 3 adopts a split structure, including a first side cover 31 and a second side cover 32. Both sides of the first side cover 31 have outwardly protruding connecting protrusions 311, and both sides of the second side cover 32 have connecting grooves 32a for the connecting protrusions to be inserted. Through the connecting protrusions 311 and the connecting grooves 32a, the first side cover 31 and the second side cover 32 can form an enclosure.

[0029] Furthermore, such as Figure 2 , Figure 3As shown, in this embodiment, the cross-section of the outer connector 3 is smaller than the cross-section at the connection between the bladder 1 and the interface 11, so that an annular groove is formed between the bladder 1 and the outer connector 3. An outer sleeve 4 is fitted inside the annular groove, so that the outer surface of the outer sleeve 4 is basically flush with the outer surface at the connection between the bladder 1 and the interface 11. The outer sleeve 4 can be made of a skin-friendly flexible material. In this embodiment, the outer sleeve 4 is made of silicone to avoid the rigid outer connector 3 from coming into contact with the skin of the neck, thereby further improving the wearing experience of this utility model.

[0030] like Figure 2 , Figure 3 As shown, in this embodiment, the end of the capsule 1 with a larger cross-section has an inlet 12 and a sealing cap 5 for sealing the inlet 12. An annular connection port 6 is formed at the inlet 12 of the capsule 1 through an injection molding process. The connection port 6 is made of rigid PVC material, and its inner wall has internal threads. The sealing cap 5 and the connection port 6 cooperate to seal the inlet 12 of the capsule 1. In this way, water or other phase change materials can be filled into the receiving cavity 1a of the capsule 1 through the inlet 12. Furthermore, a sealing ring 13 is also provided at the inlet 12 of the capsule 1. The sealing ring 13 surrounds the connection port 6 and can cooperate with the sealing cap 5 to improve the sealing performance.

[0031] The assembly process of this utility model is as follows: First, insert the inner connector 2 into the interface 11 of the first bladder 1, then put the outer cover 4 into the first bladder 1 and move it to a non-connection position to avoid the outer cover 4 interfering with the subsequent connection. Then, insert the other end of the inner connector 2 into the interface 11 of the second bladder 1, and cover the first side cover 31 and the second side cover 32 at the interface 11 of the two bladders 1. Then, simultaneously perform ultrasonic welding on the first side cover 31 and the second side cover 32 to connect the first side cover 31, the second side cover 32, the inner connector 2 and the interface of the two bladders 11 into one unit.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0033] Although this document frequently uses terms such as capsule 1, inner connector 2, outer connector 3, and sealing cap 5, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
