Description

Cooling neck band and method of manufacturing the same

[0001] The present invention relates to a cooling neck band and a method for manufacturing the same, and more specifically, to a cooling neck band and a method for manufacturing the same in which a Phase Change Material (PCM) capable of maintaining a cooling sensation on the wearer's neck for a long time is filled inside by blow molding one of PE, PP, PET, EVA, or nylon, thereby allowing it to be easily worn on the wearer's neck, not easily detached even with prolonged use or excessive movement, and having robustness that prevents easy breakage.

[0002] Generally, heat exhaustion can occur during outdoor activities in hot summer weather due to the body losing a significant amount of heat in high outdoor temperatures, or heatstroke can occur in workers who work for long periods in industrial sites handling thermal energy.

[0003] To prevent accidents caused by heat as described above, ice packs filled with ice, or frozen towels or water bottles kept in a refrigerator, were applied to the face, neck, and other parts of the body to induce a sensation of coldness and cool the body.

[0004] There were problems with ice packs used for temporary body cooling, as the ice melted easily and had to be replaced frequently, and with cold towels, the inconvenience of having to repeatedly put them in and take them out of the refrigerator to maintain the coldness.

[0005] Furthermore, in addition to the problem of clothes getting wet due to condensation caused by the melting ice in the ice pack and water from the cold towel, there was also a problem where physical abnormalities such as headaches could occur when the ice pack or cold towel came into contact with the body or was placed around the neck due to the large temperature difference between the ice in the ice pack and the coldness of the refrigerator towel and the body's warmth.

[0006] To solve this, Patent Document 1 proposes an ice neck band using a phase change material that allows the neck band to be easily worn around a person's neck and provides a cooling sensation for a long time by maintaining the cold air transmitted to the neck of the person wearing the neck band at a constant temperature for a long time. The composition includes a band wearing member that can be worn in a wrapping manner, an ice pack embedded with a phase change material installed on one side of the band wearing member to absorb heat generated from the human body and provide a cooling sensation, a pack protection member coupled to the back side of the ice pack to attach and detach the ice pack to the band wearing member, and a cold air leakage prevention member coupled to the upper and lower sides of one side of the band wearing member to prevent the cold air of the ice pack from leaking out to the outside.

[0007] However, in order to wear and remove the band, the band member must be attached or tied with Velcro, and there are side effects such as skin irritation due to the rough surface of the Velcro, and problems such as it easily coming loose or falling off the body when worn for a long time.

[0008] In particular, since ice packs containing phase change materials are made of vinyl or film, the film is often easily torn or damaged, and if the film is torn, there are problems such as the internal phase change material leaking out.

[0009] Accordingly, we propose a cooling neck band that does not tear or break.

[0010] The present invention was devised to solve the problems of the aforementioned prior art, and the objective of the present invention is to provide a cooling neck band and a method for manufacturing the same, which is manufactured by blow-molding one of PE, PP, PET, EVA, and nylon so that PCM can be filled inside, thereby allowing it to be easily worn around the wearer's neck, not easily detaching even with prolonged use or excessive movement, and having robustness that prevents easy breakage.

[0040] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0041] Prior to the description of the present invention, the following specific structural or functional descriptions are provided merely for the purpose of illustrating embodiments according to the concept of the present invention. Embodiments according to the concept of the present invention may be implemented in various forms and should not be interpreted as being limited to the embodiments described herein.

[0042] In addition, since embodiments according to the concept of the present invention may be subject to various modifications and may take various forms, specific embodiments are illustrated in the drawings and described in detail in this specification. However, this is not intended to limit the embodiments according to the concept of the present invention to specific disclosed forms, and it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention.

[0043] In addition, the configurations of the present invention are interpreted to include not only direct contact or connection but also contact or connection between configurations through other configurations within the same scope.

[0044] Figure 1 attached is a drawing showing a cooling neck band according to the present invention, Figure 2 is a drawing showing the cooling neck band according to the present invention viewed from a different direction, Figure 3 is a cross-sectional view showing the structure of the cooling neck band according to the present invention, Figure 4 is a drawing showing a stopper of a sealing part provided in the cooling neck band according to the present invention, Figure 5 is a drawing showing the cooling neck band according to the present invention in a state of use, and Figure 6 is a drawing showing another embodiment of the cooling neck band according to the present invention, showing an example in which a plurality of cold heat transfer plates provided in the cooling neck band are installed.

[0045] As illustrated in these drawings, the cooling neck band according to the present invention can provide a cooling sensation to the wearer by wearing it around the wearer's neck.

[0046] Phase Change Materials (PCMs) are substances that accumulate or release stored heat through a type of physical change process in which they transition from one state to another, such as from solid to liquid, liquid to solid, liquid to gas, or gas to liquid.

[0047] As described, the cooling neck band according to the present invention preferably includes a main body (110).

[0048] It is preferable that the above main body (110) be formed in a shape that wraps around the wearer's neck and has a 'horseshoe' shape with a portion cut out on the front side so as to be worn in a way that wraps around the wearer's neck, through elastic parts (114) extending on both sides centered on the neck part (112) that wraps around the wearer's neck, so that it can be worn in a way that wraps around the wearer's neck.

[0049] It is preferable to blow mold one of the raw materials PE, PP, PET, EVA, and nylon so that the main body (110) has an internal space filled with PCM (118) that reacts with the external temperature to create a cooling effect.

[0050] As described above, the cooling neck band according to the present invention preferably includes a sealing portion (120).

[0051] It is preferable that the sealing part (120) be installed in an injection port (122) formed to fill PCM (118) into the internal space of the main body (110) so as to seal the filled PCM.

[0052] Preferably, this sealing part (120) is formed such that an injection port (122) is formed to protrude outwardly so as to fill the internal space of the main body (110) with PCM (118), and a stopper (124) is injection molded to seal the injection port (122) and installed in the injection port (122).

[0053] It is preferable that the above stopper (124) be installed to be sealed to the injection port (122) by a screw fastening method, and that the stopper (124) be formed with an opening / closing confirmation part (126) to check whether it is open or closed, so that the authenticity can be verified by checking whether the stopper is open or closed through the opening / closing confirmation part (126).

[0054] Here, it is preferable that the stopper (124) be sealed by forming it into a screw-type injection molded part having a triple sealing structure, and as can be seen from the stopper of carbonated beverages such as cola and cider, the contents of the carbonated beverage do not leak out, so the PCM never leaks out.

[0055] Specifically, the opening / closing confirmation part (126) is formed to be connected to the lower end of the stopper (124), which is screw-coupled to the injection port (122), by a connecting piece (128) that can be easily broken, so that when the stopper (124) is rotated to open it, the opening / closing confirmation part (126) is connected in a way that prevents rotation. That is, it is preferable that an inner fixing projection be formed on the inner surface of the opening / closing confirmation part (126), and an outer fixing projection be formed on the outer surface of the injection port (122) to engage with the inner fixing projection to suppress rotation.

[0056] Therefore, when the stopper (124) is rotated to open it, the opening / closing confirmation part (126) is not rotated by the inner fixing projection and the outer fixing projection, and the connecting piece (128) is broken so that the opening / closing confirmation part (126) remains in the injection port (122), so that the opening / closing confirmation part (126) can be easily checked whether the stopper has been opened and thus the authenticity can be determined.

[0057] Meanwhile, the above plug (124) can be installed to be sealed in the injection port (122) by heat fusion, high-frequency bonding, or adhesive.

[0058] Meanwhile, the injection port (122), which is formed to protrude outwardly to fill the internal space of the main body (110) with PCM (118), is preferably formed by forming a recess (116) in the main body (110) and protruding from the recess (116).

[0059] When the injection port (122) is formed after the recess (116) is formed in this manner, the length of the injection port (122) protruding outward can be reduced, and if necessary, the injection port can be formed only in the recess (116) so that the injection port (122) does not protrude outward from the main body (110).

[0060] As described, the cooling neck band according to the present invention preferably further includes a cold heat transfer plate (130).

[0061] The above-mentioned cold heat transfer plate (130) is installed on the inner surface of the main body (110), and it is preferable that the PCM (118) filled in the internal space of the main body (110) reacts with the external temperature to produce a cooling effect, thereby allowing the cooled cold heat to be transferred to the wearer's neck through direct contact.

[0062] It is preferable that such a cold heat transfer plate (130) be made of a metal material having a predetermined area, and preferably be made of one of a thin aluminum plate, a copper plate, or a copper plate.

[0063] Additionally, as shown in FIG. 6, the above-mentioned cold heat transfer plates (130) may be installed in multiple numbers at predetermined intervals across the entire inner surface of the main body (110), or as shown in FIG. 1, only one may be installed at the center of the inner surface of the main body (110).

[0064] Accordingly, the cooling neck band of the present invention can more effectively transmit a cooling sensation to the wearer due to the installation of the cooling heat transfer plate (130). That is, the effect of transmitting a cooling sensation can be maximized by the cooling heat transfer plate (130) coming into direct contact with the wearer's neck.

[0065] Meanwhile, the above main body (110) may be impregnated with a conductive component and an antistatic agent, and the conductive component and the antistatic agent may be mixed with any one of PE, PP, PET, EVA, and nylon during the molding of the above main body (110) and blow-molded.

[0066] Specifically, when molding the main body (110), it is preferable to blow mold 1 to 3 parts by weight of a raw material containing a conductive component capable of suppressing static electricity and an antistatic agent together with 100 parts by weight of any one of PE, PP, PET, EVA, and nylon so as to suppress the generation of static electricity in the main body (110).

[0067] These conductive components and antistatic agents can be coated on the main body (110) or mixed into the raw material and blow injection molded.

[0068] In this way, if raw materials containing a conductive component capable of suppressing static electricity generation and an antistatic agent are molded together, the generation of static electricity can be blocked in principle. That is, static electricity is prone to occur due to the characteristics of PE, PP, PET, EVA, and nylon materials, but this can be fundamentally blocked.

[0069] In addition, the present invention may impregnate the main body (110) with a phytoncide raw material, and may mix the phytoncide raw material with any one of PE, PP, PET, EVA, and nylon during the molding of the main body (110) and blow mold it.

[0070] Specifically, when molding the main body (110), it is preferable to blow mold 1 to 10 parts by weight of phytoncide raw material together with 100 parts by weight of any one of PE, PP, PET, EVA, and nylon.

[0071] According to the present invention, the main body (110) may be coated with a phytoncide raw material or mixed with a raw material and blow injection molded, and a specific description of the phytoncide raw material will be provided later.

[0072] Figure 7 attached is a block diagram of a method for manufacturing a cooling neck band according to the present invention, Figure 8 shows the antibacterial effect of a deodorizing and antibacterial composition applied to a cooling neck band according to the present invention, and Figure 9 shows the deodorizing effect of a deodorizing and antibacterial composition applied to a cooling neck band according to the present invention.

[0073] As described above, the method for manufacturing a cooling neck band according to the present invention comprises a first step (S101) of blow-molding a main body (110) using any one of PE, PP, PET, EVA, and nylon, wherein the main body (110) is formed with an elastic portion (114) extending on both sides centered on a neck portion (112) that wraps around the wearer's neck, and has a 'horseshoe' shape with a portion cut on the forward side so as to wrap around the wearer's neck so as to be worn in a close fit that wraps around the wearer's neck, and has an internal space filled with PCM (118) that reacts with the external temperature to produce a cooling effect and becomes cool, and has an injection port (122) formed to fill the PCM (118) into the internal space, and a second step of filling the PCM (118) into the internal space of the main body (110) through the injection port (122) blow-molded in the first step (S101). It is preferable to include a step (S102), and a third step (S103) of sealing the injection port (122) filled with PCM (118) in the second step (S102).

[0074] At this time, the third step (S103) involves preparing an injection-molded stopper (124) that can be installed in the injection port (122) and installing the stopper (124) so ​​that it is sealed in the injection port (122) by a screw fastening method. It is preferable that the stopper (124) has an opening / closing confirmation part (126) formed therein to check whether it is open or closed, so that the authenticity can be verified by checking whether the stopper is open or closed through the opening / closing confirmation part (126).

[0075] Meanwhile, in the first step (S101), it is preferable to install a cold heat transfer plate (130) made of any one of an aluminum plate, a copper plate, or a copper plate having a predetermined area on the inner surface of the main body (110) so that the PCM (118) filled in the internal space of the main body (110) reacts with the external temperature to produce a cooling effect and the cooled cold heat can be transferred to the wearer's neck through direct contact.

[0076] These cold heat transfer plates (130) can be injection molded so as to be fixed integrally when the main body (110) is formed by blowing, and can be fixed by attaching them using an adhesive after blowing the main body (110).

[0077] By providing the present invention configured as described above, it can be easily worn on the wearer's neck, does not easily detach even with prolonged use or excessive movement, and can maintain a cooling sensation on the wearer's neck for a long time.

[0078] In particular, the present invention can maximize cooling performance by installing the above-mentioned cold heat transfer plate (130).

[0079] Meanwhile, in the first step (S101) above, it is preferable to blow-mold 1 to 3 parts by weight of a raw material containing a conductive component capable of suppressing static electricity and an antistatic agent together with 100 parts by weight of any one of PE, PP, PET, EVA, and nylon to mold the main body so as to suppress the generation of static electricity.

[0080] In addition, the fan body can be coated after molding without mixing conductive components and antistatic agents capable of suppressing static electricity generation into the raw material.

[0081] Meanwhile, in the first step (S101) above, it is preferable to blow mold 1 to 10 parts by weight of phytoncide raw material together with 100 parts by weight of any one of PE, PP, PET, EVA, and nylon raw material, and the phytoncide may be coated after molding the main body without mixing it with the raw material.

[0082] Phytoncide is a compound word formed from the Greek words Phyton, meaning 'plant,' and cide, meaning 'bactericidal power,' and refers to a bactericidal substance secreted by plants. The term originated in 1930 when Professor B.P. Tokin of Leningrad University discovered that odorous substances emitted from garlic, onions, and pine trees kill protozoa such as amoebas, as well as bacteria causing typhoid fever, dysentery, and tuberculosis. He named the substance that causes this phenomenon phytoncide. Recently, in a broader sense, it has come to refer collectively to aromatic antibiotic substances emitted by trees into the air or soil to defend themselves against pests or microorganisms in the surroundings.

[0083] The main components of these phytoncides are volatile organic compounds of the terpene family, and they are known to have antibacterial, deodorizing, sedative, and stress-relieving effects. The feeling of stress relief and increased metabolism when a person enters a dense forest and takes a forest bath is also due to the action of these phytoncides.

[0084] Phytoncide is a natural substance, not a chemically synthesized one, and is absorbed into the human body without strain, selectively sterilizing bacteria harmful to humans. In other words, phytoncide is known to perform numerous functions, including antibacterial, deodorizing, calming, and stress-relieving effects. It also cleanses and moisturizes the skin through its excellent sterilization, antibacterial, and cleansing actions, and strengthens the body's immune function.

[0085] Research results have reported that inhaling phytoncides drastically reduces the concentration of the stress hormone cortisol, and it is known that even when animal carcasses decompose in the forest, the phytoncides prevent a strong odor.

[0086] In addition, it has a sedative effect on the central nervous system, providing a pleasant sensation, extending sleep duration, and helping you achieve restful, deep sleep.

[0087] Furthermore, it has been revealed to be effective against hyperlipidemia and thrombotic heart failure by improving the blood circulation system, and it is also known for its powerful antibacterial action that does not cause resistance in the human body. Phytoncide, a natural substance, is known to be the most effective for preventing allergies without side effects, as it provides a house dust mite repellent effect of up to nearly 90%.

[0088] Meanwhile, phytoncides produced by Hinoki cypress are self-defense substances of plants that are emitted or secreted by plants to resist pathogens, pests, and fungi, and they contain antibacterial and insecticidal components.

[0089] As such, phytoncides produced from cypress trees not only provide antibacterial and air purification capabilities but also relieve stress, strengthen intestinal and cardiopulmonary functions, and enable sterilization of indoor environments.

[0090] Accordingly, the above phytoncide includes plant extracts, and the method of treating the plant extract includes all methods that enable the antibacterial properties of the plant extract to be exhibited, and may include all means that can be used by a person with ordinary knowledge in the relevant field, such as mixing the plant extract with a phase change material raw material and blow injection molding, or applying or coating the surface of the main body.

[0091] The deodorizing and antibacterial composition comprises a natural extract selected from the group consisting of mint extract, lemon extract, eucalyptus extract, and mixtures thereof.

[0092] The above-mentioned mint (Mentha) refers to a perennial herbaceous plant of the Lamiaceae family, order Lamiales, class Dicotyledon. Depending on the variety, the scent, flavor, leaf color, and shape vary. Based on the properties of the essential oil, it is classified into peppermint, spearmint, pennyroyal mint, catmint, apple mint, bowls' mint, and eau de cologne mint. It is a perennial plant native to the Mediterranean coast and is cultivated throughout Europe.

[0093] The aforementioned lemon (*Citrus limonum*) belongs to the Rutaceae family; its flowers are pale pink, and its fruit is bright or pale yellow. Essential oil is extracted by squeezing the lemon peel and has traditionally been used in perfumes due to its strong, pungent citrus scent. Lemon oil emits a unique, refreshing, and pleasant aroma; the higher the quality of the oil, the fresher and more invigorating the scent, whereas lower-quality or aged oil may emit a musty and unpleasant odor. The fruit juice and peel are widely used as seasonings in food and contain many nutrients, being rich in vitamins A, B, and X. In Spain and other European countries, it is used as a remedy, and is particularly effective for infectious diseases.

[0094] The aforementioned Eucalyptus (*Eucalyptus globulus*) belongs to the Myrtaceae family and is extracted from the leaves and twigs of the eucalyptus tree via steam distillation. Eucalyptus has a colorless, sweet scent with a menthol aroma, and expired oil turns yellow. The eucalyptus tree is native to Australia and Tasmania and is also cultivated in Mediterranean regions such as Spain and Portugal, as well as in China. Furthermore, eucalyptus oil is most effective when used as a vapor inhaler for patients with respiratory diseases such as coughs, asthma, herpes, and influenza, as well as sinusitis, bronchitis, pulmonary tuberculosis, pseudomembranous laryngitis, spasmodic pharyngitis, and diphtheria, due to its antiviral effects against these conditions. It is particularly beneficial for sore throats as it facilitates the expulsion of mucus; additionally, it is used for painless indigestion, diarrhea, cholera, and gallstones. Ozone, which is generated when some terpenes of eucalyptus oxidize in the air, has a strong bactericidal effect.
