Description

Technical Field

[0001] The utility model relates to a neck pillow for filling. Background Art

[0002] In the travel, work or leisure of needing to keep sitting posture for a long time, people usually feel tired because the head and neck can not be effectively supported. For this reason, the U-shaped pillow that can be inflated or filled with soft particles is known in the prior art.

[0003] However, traditional neck pillows only support the head and neck, but are unable to provide users with additional functions other than supporting the head and neck, such as hot compresses, cold compresses, cooling or warming up, etc., and are unable to bring users a more comfortable and relaxing experience. It is also difficult to effectively relieve fatigue and soreness caused by sitting for a long time. Utility Model Content

[0004] The purpose of this utility model is to provide a neck pillow that can enhance the user experience. In addition to supporting the head and neck, the neck pillow can provide users with additional functions such as hot compress, cold compress, cooling or warming up, effectively relieving fatigue and soreness caused by sitting for a long time, while ensuring safety of use and portability.

[0005] The utility model relates to a neck pillow for filling liquid and / or solid, the neck pillow comprising a sac body in an annular or square shape, the sac body being configured with a notch adapted to the human neck, wherein the sac body is soft and elastic, and a filling opening is configured on the outer peripheral surface of the sac body away from the notch, the filling opening having a diameter greater than or equal to 4 cm for filling the sac body with liquid and / or solid, and a cover body having a substantially flat outer surface is provided for closing the filling opening.

[0006] In the present invention, the neck pillow includes a circular or square shaped capsule with a notch configured to fit the human neck. Thus, the capsule has a generally C- or U-shaped shape and can be used like a traditional U-shaped pillow. During use, the user can align the notch with the back of the neck and slip it over the neck.

[0007] According to the present invention, a soft and elastic bladder is selected for the neck pillow. This means that the bladder has a low elastic modulus, meaning that it can undergo a certain degree of deformation under the action of an external force and can restore its shape when the external force is removed. As a result, the bladder has good flexibility and a certain degree of shape self-sustaining. A bladder made of such a material can flexibly fit various parts of the human body, such as the head, neck, and shoulders. Moreover, such a soft and elastic bladder undergoes only limited deformation when subjected to pressure and when filled with liquid and / or solid, and can maintain the basic shape of the neck pillow as a whole.

[0008] According to the present invention, the bladder is configured with a filling port on its outer peripheral surface, facing away from the notch. The filling port has a diameter of 4 cm or greater for filling the bladder with liquids and / or solids, and a cover with a substantially flat outer surface is provided for the filling port. This means that the filling port is located at the junction between the two symmetrical sides of the bladder's C- or U-shape. When the neck pillow is in use, the filling port faces away from the back of the user's neck. As a result, the filling port and its associated cover face the seat back during use, while the soft, elastic bladder still surrounds the user's neck, preventing the filling port and cover from contacting the neck. Furthermore, the outer surface of the cover, i.e., the surface exposed outside the filling port when closed, is designed to be substantially flat, thereby not hindering the user from leaning against the seat back, particularly at a certain reclined angle. This allows the cervical pillow to adapt to the physiological curvature of the cervical spine in this area, reducing the load on the cervical spine and relieving tension in the neck muscles. In addition, the diameter of the filling port is designed to be greater than or equal to 4 cm. Such a size is particularly convenient for users to fill the bladder with liquids and / or solids, such as filling ice cubes, injecting water, especially hot water or cold water, etc. In this way, the neck pillow according to the present invention can provide users with additional functions such as hot compresses, cold compresses, cooling or warming up in addition to supporting the head and neck, effectively alleviating fatigue and soreness caused by sitting for a long time. The design of the filling port size greatly facilitates users to fill, especially in shaking scenes such as airplanes and trains, which can effectively avoid spillage and ensure safety in use. At the same time, the filling port located at the connection between the symmetrical two sides of the C-shape or U-shape of the bladder can also achieve basically symmetrical filling, effectively preventing safety risks caused by the shift of the center of gravity due to unilateral filling.

[0009] In particular, it should be noted that the cover can also naturally seal the gas in the capsule, so that the neck pillow can be used similarly to a traditional inflatable neck pillow. At the same time, the soft and elastic material of the neck pillow also allows the cover to seal the capsule when the gas in the capsule is expelled, thereby achieving a lighter weight and smaller size for portable use.

[0010] In summary, the neck pillow according to the present invention can provide users with additional functions such as hot compress, cold compress, cooling or warming up in addition to supporting the head and neck, effectively relieving fatigue and soreness caused by sitting for a long time, while ensuring safety of use while maintaining its portability.

[0011] According to one embodiment of the present invention, the cover and the filling port can be threaded or snap-fitted. This threaded or snap-fit ​​connection achieves a seal between the cover and the filling port. In particular, the cover can be configured with a sealing ring. This sealing ring ensures a good air-liquid seal for the capsule.

[0012] According to one embodiment of the present invention, a hard connecting fitting can be embedded at the filling port. Here, the hard connecting fitting is used to strengthen the sealing connection between the cover body and the filling port to avoid leakage of the capsule when under pressure. At the same time, the hard connecting fitting is also suitable for use as a grip during filling to avoid deformation of the filling port under pressure. In particular, the connecting fitting can be made of polyamide (Polyamide, PA for short, commonly known as nylon). Here, the connecting fitting has the shape of a hollow cylinder. Depending on the connection method used for the cover body, the annular inner surface of the connecting fitting can be constructed to be smooth or provided with an internal thread.

[0013] According to an embodiment of the present invention, the connecting fitting may not extend into the cavity of the capsule or may only partially extend into the cavity of the capsule. By such provision, the user's comfort when leaning against the chair back is improved without leaning against the relatively hard connecting fitting.

[0014] According to one embodiment of the present invention, a raised flange can be constructed on the outer periphery of the filling port. This flange can be flush with the cover or raised above the cover. Here, the raised flange can be understood as an annular edge extending beyond the plane of the filling port, facing away from the neck pillow capsule. This raised flange can prevent solids or liquids, particularly hot water, from spilling onto the hand holding the capsule during filling, further ensuring safety during use.

[0015] According to one embodiment of the present invention, the flange and the filling port may be spaced apart, and an annular plane or truncated cone surface may be formed between the flange and the filling port. Thus, the annular plane or truncated cone surface may cooperate with the raised flange to better receive the solid and / or liquid to be filled.

[0016] According to one embodiment of the present invention, the distance from the filling port to the free end of the bladder at the notch is between 20 and 25 centimeters. This distance can be understood as the longitudinal length of the entire neck pillow. This dimensioning is particularly advantageous for aircraft water heaters, allowing the free end of the bladder at the notch to rest on the base of the water heater when the bladder is filled with hot water from under the faucet, further facilitating filling.

[0017] According to one embodiment of the present invention, the liquid can be hot water or ice water, and / or the solid can be ice cubes, fruit pits, or ceramic pellets. The capsule can be filled not only with hot water, ceramic pellets, or fruit pits, particularly cherry pits, for hot compresses, but also with ice water or ice cubes for cold compresses. It is also conceivable that the filled capsule can be chilled or heated, such as by microwave heating.

[0018] According to one embodiment of the present invention, the capsule can be made of polyvinyl chloride (PVC), silicone or fiber composite material, and / or the cover can be made of polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (also known as ABS plastic) or polyphenylene sulfide (PPS).

[0019] According to one embodiment of the present invention, the bladder body is ultrasonically welded from two injection-molded halves. Compared to blow molding, injection molding ensures a more uniform bladder wall thickness, preventing breakage due to uneven thickness. Separately molding the bladder halves also facilitates demolding. It is also conceivable to integrate the aforementioned rigid connector into the filling port through insert molding.

[0020] According to one embodiment of the present invention, one or more reinforcement structures, in particular reinforcement grooves or reinforcement ribs, may be constructed on the bladder body. The reinforcement structures may enhance the shape stability of the bladder body during use and filling.

[0021] According to one embodiment of the present invention, the neck pillow may include a fabric cover that fits over the bladder. To provide a more comfortable feel and prevent burns or frostbite during hot or cold compresses, the neck pillow is preferably fitted with the fabric cover. Advantageously, the fabric cover can be fitted over the neck pillow, leaving only the filling port exposed.

[0022] According to one embodiment of the present invention, the fabric cover can be provided with a drawstring, buckle, or snap fastener at the notch of the bladder. This prevents the cover from slipping off the user's neck during use. Alternatively or additionally, the fabric cover can accommodate at least one of a temperature measuring element, a temperature regulating element, a massage element, and a power supply element. The addition of these elements can further enhance the functionality of the neck pillow.

[0023] Other features of the present invention can be found in the drawings and the detailed description. All the features and feature combinations mentioned above in the description and the features and feature combinations mentioned below in the detailed description and / or shown individually in the drawings can be used not only in the respective combinations given, but also in other combinations or in isolation.

[0030] Figure 1 A perspective view of a neck pillow according to an embodiment of the present invention is shown. Figure 1 As shown, the neck pillow 1 for filling liquid and / or solid includes a bladder 2 in the shape of a ring or square, and the bladder is configured with a notch 4 adapted to the human neck. According to the provisions of the present invention, the bladder 2 is soft and elastic, and the bladder is configured with a notch 4 on the outer peripheral surface away from the notch 4. Figure 1 The filling port not shown in the figure has a diameter greater than or equal to 4 cm for filling the capsule 2 with liquid and / or solid, and is provided with a cover 3 having a substantially flat outer surface 3a in order to close the filling port.

[0031] According to the utility model, the neck pillow 1 can provide the user with additional functions such as hot compress, cold compress, cooling or warming up in addition to supporting the head and neck, effectively relieving fatigue and soreness caused by sitting for a long time, while ensuring its safety of use and portability.

[0032] exist Figure 1 In the embodiment, the capsule 2 of the neck pillow 1 is exemplarily annular with a notch 4, so the capsule 2 is C-shaped as a whole. Without being limited thereto, a square capsule 2 with a notch 4 can also be considered, so that the capsule 2 is U-shaped as a whole.

[0033] Here, the C-shaped bladder 2 can be divided into three sections: a first section 2a, a second section 2b, and a connecting section 2c between the first and second sections 2a, 2b. These three sections surround and contact the user's neck during use. The first and second sections 2a, 2b can each be attached to the user's shoulders, while the connecting section 2c can be placed behind the neck. If necessary, the connecting section 2c can also be placed in front of the neck to apply a hot or cold compress to the throat.

[0034] During use, the cover 3 can enclose liquids, solids, and / or gases within the bladder 2, thereby supporting the user's head and neck. The large design of the filling port facilitates the filling of liquids and / or solids into the bladder 2, providing additional functions such as heat and cold compresses, cooling, or warming, effectively alleviating fatigue and soreness caused by prolonged sitting. The liquid can be hot or ice water, and / or the solid can be ice cubes, fruit cores, or ceramic pellets.

[0035] The bladder 2 is configured with a filling port on its outer circumference facing away from the notch 4. This means that the filling port is located on the outer circumference of the connecting section 2c of the bladder 2. Advantageously, the bladder 2 can be constructed as a mirror-symmetrical structure, with the filling port located on its plane of symmetry. This allows for substantially symmetrical filling, effectively preventing safety risks caused by a shift in the center of gravity due to unilateral filling.

[0036] The outer surface 3a of the cover 3 for closing the filling port is also configured to be substantially flat, which means that the outer surface 3a of the cover 3 has no significant protrusions and thus does not hinder the user from leaning against the chair back, especially leaning against the chair back with a certain backward tilt angle.

[0037] In order to well withstand a wide temperature range when using cold and hot compresses, it is advantageous to use materials such as polyvinyl chloride, silicone or fiber composite materials for the bladder 2. Alternatively or additionally, materials such as polycarbonate, acrylonitrile-butadiene-styrene copolymer or polyphenylene sulfide can be used for the cover 3.

[0038] Particularly advantageously, the bladder 2 can be ultrasonically welded from two injection-molded half-shells. A half-shell can be understood as a longitudinally sectioned halves of the bladder 2, each comprising a portion of the first section 2a, a portion of the second section 2b, and a portion of the connecting section 2c. Manufacturing the bladder 2 in this manner allows for easy demolding and uniform thickness. Ultrasonic welding effectively ensures the strength of the connection between the two half-shells.

[0039] Figure 2 An exploded view of a neck pillow according to an embodiment of the present invention is shown. Figure 2 In order to more clearly show the outer contour of the neck pillow, an outline frame is additionally shown.

[0040] Figure 2 In the neck pillow shown, the capsule 2 and the cover 3 are separated from each other. Figure 1 The filling port 5 is enclosed by the cover 3. According to the present invention, the filling port 5 has a diameter greater than or equal to 4 cm, so that solids and / or liquids can be easily passed through it to ensure safety in use. The radial dimension of the filling port 5 requires the thickness of the neck pillow 1 to be equal to or greater than the radial dimension. Figure 2 It can be seen that the filling opening 5 is away from the notch 4 of the capsule 2. In order to realize a generally planar filling opening 5, an annular protrusion protruding from the outer circumference of the capsule 2 facing away from the notch 4 is formed.

[0041] In the current embodiment, the capsule 2 and the cover 3 can be threadedly connected to each other. To this end, an external thread 3c is constructed on the cover 3. In order to facilitate the user to apply the tightening force, a plurality of, here three, screw ears 3b are provided on the outer circumference of the outer surface 3a of the cover 3. Correspondingly, an internal thread matching the external thread 3c is provided at the filling port 5 of the capsule 2. Thus, the user can simply close the filling port 5 by screwing the cover 3 into the filling port 5. In order to prevent leakage of liquid or gas, a sealing ring (not shown) can preferably be provided on the cover 3.

[0042] In addition to the threaded connection, a snap-fit ​​connection between the capsule 2 and the cover 3 can also be considered. To this end, one or more movable hooks, particularly push-type hooks, can be provided on the cover or the filling port. These movable hooks can be used to detachably connect the capsule 2 and the cover 3 to each other.

[0043] Particularly advantageously, a hard connecting fitting 6 can be embedded in the filling port 5. The connecting fitting 6 is Figure 23 is shown as a ring surrounding the filling port 5. The connecting fitting 6 can have the shape of a hollow cylinder. Corresponding to the external thread 3c of the cover body 3, the inner surface of the ring of the current connecting fitting 6 can be provided with an internal thread. The connecting fitting 6 can be used to strengthen the sealing connection between the cover body 3 and the filling port 5 and is also suitable for being used as a grip during filling to prevent the filling port 5 from being deformed by pressure. In particular, the connecting fitting 6 can be made of polyamide. It is also preferred that the above-mentioned hard connecting fitting 6 is integrally formed at the filling port 5 by insert injection molding.

[0044] In order to improve the comfort during use, the connecting fitting 6 whole or most of it is located in the region of the annular protruding neck of the capsule 2. This means that the connecting fitting 6 does not extend into the cavity of the capsule 2 or only partially extends into the cavity of the capsule 2.

[0045] In order to increase safety during filling, it is advantageously provided that a raised flange 7 is formed on the outer circumference of the filling opening 5, said flange 7 being flush with the cover 3 closing the filling opening 5 or said flange 7 being higher than the cover 3. In this case, the raised flange 7 can prevent solids or liquids, in particular hot water, from spilling out when filling the neck pillow 1.

[0046] like Figure 2 As shown, the flange 7 and the filling port 5 can be spaced a certain distance apart, and an annular plane or a truncated cone surface can be constructed between the flange 7 and the filling port 5. The annular plane or the truncated cone surface can cooperate with the raised flange 7 to better receive the solid and / or liquid to be filled.

[0047] Particularly advantageously, the distance between the filling port 5 and the free ends 2d, 2e at the notch 4 of the bladder 1, i.e., the overall longitudinal length of the neck pillow 1, can be designed to be between 20 and 25 centimeters. This dimensioning is particularly advantageously adapted to the structure of an aircraft water heater, allowing the free ends 2d, 2e at the notch 4 of the bladder 1 to be supported to a certain extent on the base of the water heater when the bladder 2 is filled with hot water under the water heater faucet, thereby further facilitating filling by the user.

[0048] In order to improve the shape stability of the bladder 2 during filling and use, one or more reinforcement structures, in this case reinforcement grooves, may be constructed on the bladder 2. Figure 2 As shown, first and second reinforcement grooves 8a and 8b are formed on the first and second sections 2a and 2b, respectively. The first and second reinforcement grooves 8a and 8b extend over a substantial portion of the first and second sections 2a and 2b, respectively, and are arcuate in shape. Alternatively to reinforcement grooves recessed into the surface of the bladder 2, reinforcement ribs protruding from the surface of the bladder 2 may also be used.

[0049] Particularly preferably, the neck pillow 1 may also include Figure 2A fabric cover, not shown, can be put on the bladder 2. The fabric cover provides the user with a more comfortable touch and avoids burns or frostbite during hot or cold compresses. In order to facilitate filling, the fabric cover does not cover the filling port 5. Exemplarily, the fabric cover can only wrap the first section 2a, the second section 2b and the connecting section 2c of the bladder, and the connecting section 2c is designed as an elastic opening surrounding the annular protruding neck. Thus, under the current embodiment, the filling port 5 of the bladder 2, the raised flange 7 and the annular plane or truncated cone surface located therebetween are exposed outside the fabric cover, thereby facilitating the user to fill the bladder 2 with solids and / or liquids.

[0050] Advantageously, it can also be considered that the fabric cover is provided with a drawstring, buckle or snap button at the notch of the bladder to prevent the neck pillow 1 from slipping off the user's neck during use. Alternatively or additionally, the fabric cover can accommodate at least one of a temperature measuring element, a temperature regulating element, a massage element and a power supply element. Exemplarily, the temperature measuring element can indicate the temperature of the bladder 2 to the user and can be, for example, a thermocouple or a temperature indicator card; the temperature regulating element can heat or cool the bladder 2 and can be, for example, a heating wire, a heating plate, a semiconductor refrigeration plate or a phase change material (PCM); the massage element can massage the neck and / or shoulders to relax muscles, invigorate the spirit, eliminate fatigue, etc. and can be, for example, a vibration motor, a rotary motor or an electrode sheet; the power supply element can supply power to the aforementioned elements and can be, for example, a dry cell or a storage battery. In order to accommodate these elements, it can be considered to provide corresponding pockets on the fabric cover.

[0051] The present invention is not limited to the embodiments shown, but includes or extends to all technical equivalents that fall within the effective scope of the appended claims. Positional descriptions selected in the specification, such as top, bottom, left, right, etc., refer to the direct description and the accompanying drawings and can be transferred to the new position according to the meaning when the position changes.

[0052] The features disclosed in the present application may be essential and implementable both individually and in any combination for the realization of the exemplary embodiments in various configurations.

[0053] Although the present invention has been disclosed above in terms of preferred embodiments, this is not intended to limit the present invention.
