Description

The present invention relates to a double neckband with a thermal insulation layer and a manufacturing method thereof. More specifically, the present invention relates to a double neckband with a thermal insulation layer, which is composed of an inner tube with a built-in heat storage material and an outer tube that is sealed while containing the inner tube and the thermal insulation material to form the outer appearance, and a manufacturing method thereof.

The present invention relates to a double neckband with an insulating layer that improves aesthetics and design by configuring at least a portion of the outer tube to be transparent and configuring the inner tube to have a color so that the inner tube can be seen through, and a method for manufacturing the same.

The present invention relates to a double neckband with an insulating layer that can be used in both summer and winter using heat storage material, and a method for manufacturing the same.

The present invention relates to a double neckband with an insulating layer that prevents bias and minimizes emotional frustration by joining a portion of the inner tube together when sealing the outer tube, thereby limiting the movement of the inner tube inside the outer tube, and a method for manufacturing the same.

The present invention relates to a double neckband with an insulating layer that uses air as an insulating material, making it possible to reduce weight, increase insulating efficiency, and eliminate emotional dissatisfaction by providing a full, comfortable fit, as well as a method for manufacturing the same.

The present invention relates to a double neckband with an insulating layer that can improve airtightness by forming an outer tube by layering and joining different materials, and a method for manufacturing the same.

For example, when construction workers, athletes, students taking exams, or the general public engage in indoor or outdoor activities during the hot summer weather, their bodies can generate a large amount of heat, causing a rapid decline in bodily functions and even leading to heatstroke.

Therefore, to cool down the body, you can drink cold water or eat ice cream, or get into an air-conditioned space.

However, continually drinking cold water or consuming ice to cool the body may actually lead to headaches or stomach aches, and there are limits to finding an air-conditioned space.

On the other hand, another way to cool down your body on a hot day is to wipe parts of your body, including your face, with a damp towel, which will make you feel cooler due to the effect of evaporation.

You can also feel cooler by putting ice in your pocket or somewhere else and letting it touch your body.

However, such methods require the user to repeatedly wet the towel or replenish ice in a pocket as the water evaporates, which is extremely inconvenient, and they also have the problem that they cannot be used in environments where water or ice cannot be easily found nearby.

For this reason, Patent Document 1 discloses a neck ice cooling package that, as shown in Figure 1, when worn around the neck, provides a feeling of coolness due to the cooling medium, can be reused by quick freezing, and is easy to carry and store.

Patent Document 2 also discloses a neck cooling tube, as shown in Figure 2, that can regulate temperature while easily ensuring safety during transport and storage.

Patent Document 3 discloses a wearable cooling tube that, as shown in FIG. 3, has a fiber layer on the surface of the tube body that can be cooled by water evaporation, so that when worn by a user in a high-temperature environment, the self-cooling cooling effect can cool the heat generated by the body, maximizing the cooling effect.

Patent document 4 also discloses a neck cooling device that can check the degree to which the refrigerant material contained inside has melted, as shown in Figure 4.

However, these conventional technologies have problems such as reduced cooling efficiency due to the fact that the built-in refrigerant medium is made of a single material and the usage time is extremely short.

In addition, even though the product is meant to be worn in an exposed position, it is poorly designed and undesirable.

And when stored in a freezer, it has a fixed operating temperature, which poses the problem of being less convenient for use by sensitive infants.

In addition, the entire inside of the tube is filled with the refrigerant medium, making it impossible to reduce weight, and the cold air contained in the refrigerant medium comes into close contact with the outside through the tube, which undesirably induces a loss of cold air.

Republic of Korea Patent No. 10-1977325 Republic of Korea Patent No. 10-1948865 Republic of Korea Patent No. 10-2306013 Republic of Korea Patent Publication No. 10-2020-0097644

The present invention is intended to solve the problems of the conventional technology and aims to provide a double neckband with a thermal insulation layer, which is composed of an inner tube with a built-in heat storage material and an outer tube that is sealed while containing the inner tube and thermal insulation material to form the outer appearance, and a method for manufacturing the same.

Another object of the present invention is to provide a double neckband with an insulating layer that improves aesthetics and design by configuring at least a portion of the outer tube to be transparent and configuring the inner tube to have a color so that the inner tube can be seen through, and a method for manufacturing the same.

Another object of the present invention is to provide a double neckband with an insulating layer that can be used in winter as well as summer by using heat storage material, and a method for manufacturing the same.

It is yet another object of the present invention to provide a double neckband and method of manufacture with an insulating layer that prevents bias and minimizes emotional frustration by joining a portion of the inner tube together when sealing the outer tube and limiting movement of the inner tube within the outer tube.

Another object of the present invention is to provide a double neckband with an insulating layer that uses air as an insulating material, making it possible to reduce weight, increase insulating efficiency, and eliminate emotional dissatisfaction by providing a full, comfortable fit, as well as a method for manufacturing the same.

Another object of the present invention is to provide a double neckband with an insulating layer that can improve airtightness by laminating and joining different materials to form an outer tube, and a method for manufacturing the same.

The double neckband with a thermal insulation layer according to the present invention is characterized by comprising an inner tube with a built-in heat storage material and a color on its outer surface, an outer tube that forms the outer appearance when the inner tube is housed therein and is wrapped around the user's neck, and an insulating layer filled with a thermal insulation material and having a thermal insulation function between the outer tube and the inner tube.

The insulating material is air.

The outer tube has a structure in which a first layer made of TPU (Thermoplastic Polyurethane) and a second layer made of PE (Polyethylene) are bonded together, and the second layer has a lower porosity than the first layer.

The method for manufacturing a double neckband with a thermal insulation layer according to the present invention is characterized in that it is manufactured by sequentially carrying out the following steps: a tube preparation step for preparing an inner tube having a heat storage material built in and a color on its outer surface, and an outer tube having an opening formed to accommodate the inner tube; an outer tube inversion step for exposing the inside of the outer tube to the outside and turning it inside out; an inner tube insertion step for inserting the inner tube into the inside of the inverted outer tube; an insulation injection step for injecting insulation material between the outer tube and the inner tube; and an outer tube sealing step for sealing the insulation material injected inside the outer tube so that it does not leak, thereby forming an insulation layer.

In the tube preparation step, the outer tube is characterized in that openings are formed only in the remaining portions excluding both ends.

In the tube preparation step, the opening is formed in the outer part of the outer tube, and the inner part is joined by ultrasonic bonding.

In the outer tube inversion step, an opening is formed in the outer part of the inverted outer tube, and the inner part, which is ultrasonically bonded, is housed inside the outer tube.

The double neckband with a thermal insulation layer and the manufacturing method thereof of the present invention have a thermal insulation layer composed of an inner tube with a built-in heat storage material and an outer tube that is sealed with the inner tube and the thermal insulation material contained therein to form the outer appearance.

Therefore, the formation of an insulating layer has the advantage of significantly reducing weight and slowing down the heat absorption of the heat storage material, thereby increasing the duration of the cooling sensation.

In addition, in the present invention, at least a portion of the outer tube is made transparent, and the inner tube is made to have a hue so that the inner tube can be seen through, thereby improving the aesthetics and design.

And because the heat storage material allows it to be used not only in summer but also in winter, it increases convenience of use and makes people more willing to buy it.

In addition, when sealing the outer tube, a portion of the inner tube is joined together to limit the movement of the inner tube inside the outer tube, preventing misalignment and minimizing emotional frustration.

In addition, by using air as an insulating material, it is possible to reduce weight, increase insulating efficiency, and alleviate emotional dissatisfaction by providing a full, comfortable fit.

In addition, airtightness can be improved by forming the outer tube by layering and joining different materials.

The configuration of the double neckband with the insulating layer 160 according to the present invention (hereinafter referred to as "double neckband 100") will be described below with reference to the attached FIG. 5.

Figure 5 shows a photograph of the appearance of a double neckband 100 with an insulating layer 160 according to the present invention.

Prior to this, the terms and words used in this specification and claims should not be interpreted in their ordinary and dictionary sense, but should be interpreted in a meaning and concept that corresponds to the technical idea of the present invention, based on the principle that an inventor can appropriately define the concept of a term in order to best explain his/her invention.

Therefore, it should be understood that the embodiment described in this specification and the configuration shown in the drawings are merely preferred embodiments of the present invention and do not fully represent the technical ideas of the present invention, and that there may be various equivalents and modifications that can replace them at the time of filing this application.

As shown in the drawing, the double neckband 100 according to the present invention can be stored in a freezer, then taken out and wrapped around the neck to cool the body, and in winter it can be worn warmly wrapped around the neck.

That is, the double neckband 100 has a built-in heat storage material (see reference symbol H in FIG. 6) and can be used either hot or cold due to the inner tube 120 having a color on the outer surface, and the heat storage material H can be used in various ways depending on the time and purpose of use of the double neckband 100.

The heat storage material H may be configured to contain at least one of tetradecane, hexadecane, and octadecane, so as to provide a cooling sensation to the user for a long period of time.

The heat storage material H can be made of a polymer gel and used to selectively provide a cool or warm sensation.

An outer tube 140 is provided on the outside of the inner tube 120. The outer tube 140 forms the exterior of the double neckband 100 and is the part that actually comes into contact when wrapped around the user's neck. It is ring-shaped and has an opening in one part.

The open area can then be spread open and wrapped around the user's neck, providing a feeling of coolness or warmth through the heat storage material H of the inner tube 120 built inside.

The outer tube 140 is configured so that the inside can be seen through. This is to allow the inner tube 120 built into the outer tube 140 to be seen from the outside of the double neckband 100, giving it an aesthetic feel.

In an embodiment of the present invention, the outer tube 140 is not completely transparent, but is configured to be partially see-through, so that the purple inner tube 120 can be seen from inside the outer tube 140, as shown in FIG. 5.

An insulating layer (see reference numeral 160 in FIG. 6) is provided between the outer tube 140 and the inner tube 120.

The detailed configuration of the double neckband 100 will be described below with reference to the attached Figures 6 to 8.

Figure 6 shows a schematic diagram illustrating the internal structure of a double neckband 100 with a thermal insulation layer 160 according to the present invention, Figure 7 shows a cross-sectional view of part A-A' in Figure 6 showing the internal structure of a double neckband 100 with a thermal insulation layer 160 according to the present invention, and Figure 8 shows a cross-sectional view of part B-B' in Figure 6 showing the internal structure of a double neckband 100 with a thermal insulation layer 160 according to the present invention.

First, as shown in FIG. 6, the double neckband 100 includes an inner tube 120 that is filled with a heat storage material H and is sealed. The inner tube 120 has a ring shape and is open at the bottom. The inner tube 120 is made of TPU (Thermoplastic Polyurethane) material that is harmless to the human body, and two horseshoe-shaped sheets are stacked and ultrasonically fused only at the ends.

The protruding portion (see reference symbol N in FIG. 7) that protrudes due to ultrasonic welding may cause damage to the inner surface of the outer part, so the inner tube 120 is turned inside out and the heat storage material H is injected with the protruding portion N positioned inside, and then the injection hole is sealed.

The outer tube 140 has a similar shape to the inner tube 120 and is larger than the inner tube 120, so that the inner tube 120 and the insulating material I are simultaneously filled inside.

In an embodiment of the present invention, air is used as the insulation material I filled inside the outer tube 140, and it is more preferable to use dry air with reduced humidity.

The outer tube 140 is also manufactured by stacking two horseshoe-shaped sheets like the inner tube 120 and ultrasonically fusing only the ends. Since the fused part W protruding from the ultrasonic fusing may cause chafing against the user's skin, it is preferable to fill the insulating material I inside out so that the fused part is located on the inside, as shown in Figure 7.

A shielding part 180 is provided on the outside of the outer tube 140. The shielding part 180 functions to prevent the insulation material I from leaking out after filling the inside of the outer tube 140 with the insulation material I, and the shielding part 180 is applied by ultrasonic welding.

The area where the shielding portion 180 is located is the last area to be fused after the insulation material I is filled inside the outer tube 140, and when viewed from the outer tube 140, a finishing portion (reference symbol F in FIG. 8) protruding outward is formed.

The shielding portion 180 can be configured to prevent the finishing portion F from being exposed to the outside by fusing together a tag that describes the manufacturer's trade name, logo, and brief functions.

The manufacturing method of the double neckband 100 will be described below with reference to the attached Figures 9 to 12.

Figure 9 is a process flow diagram showing the manufacturing method of the double neckband 100 with the insulating layer 160 according to the present invention, Figure 10 is an actual photograph showing the inner tube 120 and the outer tube 140 prepared in the tube preparation step S100, which is a step in the manufacturing method of the double neckband 100 with the insulating layer 160 according to the present invention, Figure 11 is an actual photograph showing the outer tube 140 turned inside out in the outer tube turning step S200, which is a step in the manufacturing method of the double neckband 100 with the insulating layer 160 according to the present invention, and Figure 12 is an actual photograph showing the inner tube 120 inserted in the inner tube insertion step S300, which is a step in the manufacturing method of the double neckband 100 with the insulating layer 160 according to the present invention.

First, as shown in FIG. 9, the double neckband 100 is manufactured by sequentially carrying out the following steps: tube preparation step S100, which prepares the inner tube 120 containing the heat storage material H and the outer tube 140 with an opening (reference symbol O in FIG. 10); outer tube inversion step S200, which exposes the inside of the outer tube 140 to the outside and turns it inside out; inner tube insertion step S300, which inserts the inner tube 120 into the inside of the inverted outer tube 140; insulation material injection step S400, which injects insulation material I between the outer tube 140 and the inner tube 120; and outer tube sealing step S500, which seals the insulation material I injected into the outer tube 140 so that it does not leak, thereby forming an insulation layer 160.

The tube preparation step S100 is a process of preparing the inner tube 120 and the outer tube 140, as shown in FIG. 10, and the inner tube 120 is filled with the heat storage material H and sealed inside.

The outer tube 140 is then made by stacking two horseshoe-shaped sheets, and then ultrasonically fusing the entire inner arc, the lower end, and only a portion of the lower part of the outer arc to join them.

Therefore, the outer tube 140 prepared in the tube preparation step S100 is prepared so that the upper outer part is open and the inside can be opened as seen in FIG. 10.

When the inner tube 120 and the outer tube 140 are prepared in the tube preparation step S100, the outer tube inversion step S200 is performed. The outer tube inversion step S200 is a process of inverting the outer tube 140 so that the inside of the outer tube 140, which is formed in two layers, is exposed to the outside. The outer tube 140 after the outer tube inversion step S200 is in the form shown in FIG. 11, which is similar to the form shown in FIG. 10.

However, the outer tube 140 prepared in the tube preparation step S100 still has a fused portion protruding outward due to the ultrasonic fusion process, but when the outer tube inversion step S200 is performed, the fused portion is positioned on the inside of the outer tube 140, which prevents emotional dissatisfaction when the tube is wrapped around the user's neck.

After the outer tube inversion step S200, the inner tube insertion step S300 is performed. That is, as shown in FIG. 12, the inner tube 120 is inserted into the outer tube 140 through the opening O.

At that time, the ultrasonically fused lower portion of the outer tube 140 accommodates both ends of the inner tube 120 to prevent separation, and the inner arc portion of the outer tube 140 is also ultrasonically fused.

Then, a portion of the opening O is fused a little further, leaving only the portion into which the insulating material I is to be injected, and the insulating material injection step S400 is performed. In the insulating material injection step S400, the inside of the outer tube 140 is filled with air, and such air is injected at a low humidity level to prevent freezing, etc.

After the insulation injection step S400, the outer tube sealing step S500 is performed. In an actual process, the outer tube sealing step S500 is performed at the same time as the insulation injection step S400 is completed. Once the outer tube sealing step S500 is completed, the outer tube 140 with the inner tube 120 built in may be formed as shown in FIG. 5, and the insulation layer 160 is formed inside the outer tube 140 by the insulation material I.

Meanwhile, the double neckband 100 may be implemented by changing the connection structure of the inner tube 120 and the outer tube 140 as shown in FIG. 13.

Figure 13 is a cross-sectional view showing another embodiment of the connection structure of the outer tube 140 and the inner tube 120 in the double neckband 100 with the insulating layer 160 according to the present invention. In the above embodiment, the inner tube 120 is inserted into the outer tube 140 without being connected to it, but in another embodiment, the inner tube 120 is configured in a state where it is partially connected to the outer tube 140.

That is, the inner tube 120 may be provided with an extension 128 integrally formed on the outside thereof, and the extension 128 may be ultrasonically fused together with the finishing portion F and the shielding portion 180.

As a result, the inner tube 120 maintains a constant distance inside the outer tube 140 without changing the separation distance, allowing the function of the insulating layer 160 to be efficiently performed.

The scope of the present invention is not limited to the above-described embodiment, and many other variations based on the present invention would be possible for a person skilled in the art within the above-described technical scope.

For example, in the embodiment of the present invention, the outer tube 140 is made of a transparent material so that the inner tube 120 can be seen through, but this can also be modified as shown in Figures 14 and 15.

Figure 14 is a photograph showing the appearance of another embodiment of a double neckband 100 with a thermal insulation layer 160 according to the present invention, and Figure 15 is a vertical cross-sectional view of part C-C' in Figure 14 showing the internal structure of another embodiment of a double neckband 100 with a thermal insulation layer 160 according to the present invention. The outer band does not necessarily have to be transparent as in Figure 14, and the outer tube 140 can be modified to have multiple layers joined together as in Figure 15.

More specifically, the outer tube 140 contains the insulating material I inside, and is preferably configured to have low porosity so as to prevent leakage to the outside.

Therefore, the outer tube 140 has a form in which a first layer 142 and a second layer 144 are bonded together as shown in FIG. 15, and the second layer located on the outside is configured to have a lower porosity than the first layer, thereby minimizing leakage of the insulation material I.

In an embodiment of the present invention, the first layer is made of TPU (Thermoplastic Polyurethane) and the second layer is made of PE (Polyethylene), and it is preferable that the second layer is made thicker than the first layer to minimize air leakage.

An adhesive may be provided between the first and second layers to maintain their adhesion.
