Description

[Technical Field]

[0001] The present invention relates to a cooling cylinder including a pressure-resistant container equipped with an injection valve and containing a cooling agent, and a cap attached to the pressure-resistant container, and a cooling method using the cooling cylinder. [Background technology]

[0002] In summer, when cooling textile products such as towels, handkerchiefs, wet towels, and tissues, a cooling aerosol is known that uses the heat of vaporization of a cooling agent (propellant) to instantly freeze the target textile product (see, for example, Patent Document 1).

[0003] According to Patent Document 1, when cooling a portable towel sealed in a packaging bag, part of the packaging bag is opened to form an opening, a spray nozzle for a cooling aerosol is inserted into this opening, and a spray button is pressed to spray the cooling agent into the packaging bag, thereby instantly cooling or freezing the portable towel. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-17027 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the cooling aerosol described in Patent Document 1 sprays a coolant from a long, thin spray nozzle, so while it is suitable for cooling relatively small textile products sealed in a packaging bag such as that described in Patent Document 1, it poses problems when directly cooling relatively large textile products or textile products in an unpackaged state.

[0006] For example, when cooling a relatively large textile product such as a towel that is not normally packaged, the cooling aerosol described in Patent Document 1 requires repeated spraying while moving the aerosol at a certain distance from the textile product. In this case, some of the coolant may not reach the textile product and be wasted, or the coolant may evaporate before reaching the textile product, resulting in a decrease in cooling efficiency. Furthermore, when the surface area of ​​a textile product is large, it takes time to cool the entire textile product, and the temperature of the area where the coolant was initially sprayed may rise, requiring the product to be cooled again.

[0007] As described above, the cooling aerosol described in Patent Document 1 can only be used in limited situations, and is not convenient for everyday use.

[0008] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an easy-to-use cooling cylinder that can instantly and efficiently cool textile products such as towels, and a cooling method using the cooling cylinder. [Means for solving the problem]

[0009] The cooling cylinder according to the present invention for solving the above problems has the following characteristic configuration: A cooling cylinder comprising a pressure-resistant container containing a coolant and provided with an injection valve, and a cap attached to the pressure-resistant container, The cap has an injection portion connected to the injection valve and an abutment portion that abuts against an object to be cooled.

[0010] With this cooling cylinder, when the coolant sealed in the pressure-resistant container is sprayed from the spray valve, it travels from the spray portion of the cap to the contact portion. Since the contact portion is in contact with the object to be cooled, for example, if the object to be cooled is a textile product such as a towel, when the coolant is sprayed from the spray portion, it spreads quickly between the contact portion and the textile product, instantly cooling the textile product. Furthermore, because the contact portion is in contact with the textile product, the sprayed coolant does not come into excessive contact with the outside air, suppressing a temperature rise in the cooled area and allowing the textile product to be cooled efficiently. Furthermore, this type of cooling cylinder is easy to use and convenient for everyday use.

[0011] In the cooling cylinder according to the present invention, The contact portion preferably has an annular cooling surface provided so as to surround the injection portion.

[0012] With this cooling cylinder, the coolant sprayed from the spray unit penetrates between the annular cooling surface and the object to be cooled (for example, a textile product such as a towel), allowing the textile product to be cooled instantly and efficiently. Furthermore, because the annular cooling surface is arranged to surround the spray unit, the annular cooling surface firmly presses the sprayed area of ​​the object to be cooled, and the coolant sprayed from the spray unit spreads evenly between the annular cooling surface and the textile product, allowing the textile product to be cooled uniformly.

[0013] In the cooling cylinder according to the present invention, The injection unit preferably has an injection port through which the coolant is injected, and a diffusion space in which the coolant injected from the injection port is diffused and vaporized.

[0014] With this cooling cylinder, the coolant ejected from the injection valve is sprayed from the nozzle of the injection unit, then diffuses and vaporizes in the diffusion space, and reaches the object to be cooled (for example, a textile product such as a towel) via the annular cooling surface (contact portion). In this way, diffusing and vaporizing the propellant in the diffusion space makes it easier for the coolant to be distributed evenly over the annular cooling surface, thereby improving the cooling efficiency of the textile product.

[0015] In the cooling cylinder according to the present invention, It is preferable to use the device in an inverted state with the cap facing downwards.

[0016] The cooling cylinder of this configuration can be used in an inverted position with the cap facing downwards, making it easy to work in, particularly when cooling relatively large textile products such as towels, and making it a user-friendly product.

[0017] In the cooling cylinder according to the present invention, The coolant is preferably one selected from the group consisting of liquefied petroleum gas (LPG), dimethyl ether (DME), fluorocarbons, nitrogen, nitrous oxide, and carbon dioxide.

[0018] According to the cooling cylinder of this configuration, since the liquefied gas or compressed gas that is commonly used as a propellant as described above is used as the cooling agent, no special approval is required, and it can be a low-cost, reliable product.

[0019] In the cooling cylinder according to the present invention, The object to be cooled is preferably a textile product.

[0020] With this cooling cylinder, the spray part and the contact part work together to instantly cool the textile product. Furthermore, since the object to be cooled is a textile product, a cooling item suitable for everyday use can be easily obtained.

[0021] In the cooling cylinder according to the present invention, The textile product is preferably one selected from the group consisting of towels, handkerchiefs, wet towels, tissues, masks, gauze, and clothing.

[0022] With the cooling cylinder of this configuration, even if the object to be cooled is a textile product with a relatively large surface area as described above, the entire textile product can be cooled by pressing the cooling cylinder against the surface of the textile product multiple times or by sliding the cooling cylinder over the surface of the textile product.

[0023] In the cooling cylinder according to the present invention, The contact portion preferably contacts the object to be cooled so as to freeze the object.

[0024] The cooling cylinder of this configuration can freeze an object to be cooled by contacting the contact part with the object, thereby maintaining a high cooling effect and making it suitable for use during the recent hot summers. Furthermore, a high cooling effect can be easily obtained without the need for equipment such as a refrigerator.

[0025] In the cooling cylinder according to the present invention, It is preferable that a frozen pattern corresponding to the shape of the contact portion is formed on the cooling target.

[0026] With this type of cooling cylinder, a frozen pattern is formed on the object to be cooled according to the shape of the contact part, so by freely changing the shape of the contact part, various frozen patterns can be formed on the object to be cooled. A cooling cylinder with such unique features can provide added value that is likely to attract the interest of users.

[0027] The cooling method according to the present invention for solving the above problems has the following characteristic configuration: A cooling method using the cooling cylinder described in any one of the above, a placing step of placing the cooling cylinder in an inverted state on an object to be cooled; a pressing step of pressing the cooling cylinder against the object to be cooled to spray the coolant; a maintaining step of maintaining the cooling cylinder pressed against the object to be cooled to allow the coolant to permeate the object to be cooled; a lifting step of lifting the cooling cylinder to stop the injection of the coolant; The purpose is to encompass the above.

[0028] According to this cooling method, when the pressing step and the subsequent maintaining step are performed, the coolant sealed in the pressure-resistant container is sprayed from the spray valve and transferred from the spray portion of the cap to the abutting portion. The coolant then spreads quickly between the abutting portion and the textile product, penetrating the textile product and instantly cooling it. Furthermore, because the abutting portion is in contact with the textile product, the sprayed coolant does not come into excessive contact with the outside air, suppressing temperature rise in the cooled portion and allowing the textile product to be cooled efficiently. Furthermore, the placing step allows the cooling cylinder to be used in an inverted position with the cap facing downwards, making the user's working posture more comfortable.

[0029] In the cooling method according to the present invention, The maintaining step is preferably performed until the object to be cooled is frozen.

[0030] According to the cooling method of this configuration, a high cooling effect can be maintained by performing the maintenance step until the object to be cooled is frozen, making it suitable for use during the extremely hot summer months of recent years. Furthermore, a high cooling effect can be easily obtained and the object to be cooled can be frozen even without facilities or equipment such as a refrigerator.

[0031] In the cooling method according to the present invention, In the maintaining step, it is preferable to form a frozen pattern on the object to be cooled according to the shape of the contact portion.

[0032] With this cooling method, a frozen pattern is formed on the object to be cooled according to the shape of the contact area, so by freely changing the shape of the contact area, various frozen patterns can be formed on the object to be cooled. A cooling method with such unique features can provide added value that is likely to attract people's attention. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0034] Hereinafter, embodiments of the cooling cylinder and the cooling method of the present invention will be described, but the present invention is not intended to be limited to the following description and drawings.

[0035] <Overall configuration of cooling cylinder> The cooling cylinder of the present invention is primarily used to cool textile products. In this context, "cooling" refers not only to lowering the temperature of the object to be cooled but also to freezing the object. Examples of textile products to be cooled include everyday items such as towels, handkerchiefs, wet towels, and tissues, as well as sanitary items such as masks and gauze. When a cooling agent is sprayed onto these objects, the temperature drops rapidly due to the heat of vaporization of the cooling agent, resulting in a cooling effect. Continued spraying of the cooling agent onto the object freezes the surface of the object, incorporating moisture in the air and surrounding areas. A frozen object (e.g., a frozen towel) can maintain a high cooling effect, making it ideal for use during the recent heatwaves. Furthermore, a high cooling effect can be easily achieved and the object can be frozen without the need for equipment such as a refrigerator. It is even more effective if the object to be cooled also contains moisture, as the moisture freezes, resulting in a longer-lasting cooling effect.

[0036] 1 is a perspective view of a cooling cylinder 100 according to one embodiment of the present invention. The cooling cylinder 100 comprises a pressure-resistant container 10 and a cap 20. (a) shows the pressure-resistant container 10 with the cap 20 attached, and (b) shows the pressure-resistant container 10 with the cap 20 removed. Details of the cooling cylinder 100 will be described below.

[0037] <Pressure-resistant vessel> The pressure-resistant container 10 is provided with an injection valve 11. The injection valve 11 is configured to include a valve stem 11a and a valve mechanism 11b (see FIG. 2). A coolant R (see FIG. 2) is sealed inside the pressure-resistant container 10. The coolant R is ejected from the valve stem 11a, which is located outside the pressure-resistant container 10, via the valve mechanism 11b, which is located inside the pressure-resistant container 10. Although not shown, a tube for sucking the coolant R may be connected to the valve mechanism 11b.

[0038] The pressure-resistant container 10 is generally made of metal such as aluminum, stainless steel, iron, tin, or copper, but may also be made of resin or glass as long as it is strong enough to withstand the internal pressure when filled with the coolant R. The capacity of the pressure-resistant container 10 is not particularly limited, but is preferably about 50 to 500 mL in consideration of its use as a cooling cylinder (cooling aerosol).

[0039] The refrigerant R can be any refrigerant known in the art as a propellant. Examples of the refrigerant R include liquefied gases such as liquefied petroleum gas (LPG), dimethyl ether (DME), and fluorocarbons (e.g., HFO-1234ze), as well as compressed gases such as nitrogen, nitrous oxide, and carbon dioxide. These liquefied gases and compressed gases are commonly used as aerosol propellants, so no special approval is required to manufacture a refrigerant cylinder (refrigerant aerosol). This allows for a low-cost, reliable product.

[0040] In addition to the above-mentioned cooling agent R, other ingredients (for example, ingredients used in cosmetics) can also be enclosed in the pressure-resistant container 10. Examples of other ingredients include fragrances, essential oils, moisturizers, UV absorbers, deodorants, etc. By enclosing ingredients used in cosmetics together with the cooling agent R in the pressure-resistant container 10, the cooling cylinder 100 of the present invention can also be used as a cosmetic product. When the cooling cylinder 100 of the present invention is used as a cosmetic product, it is preferable to use compressed gas as the propellant.

[0041] <Cap> The cap 20 functions as an actuator that operates the injection valve 11 by being attached to the pressure-resistant container 10. The cap 20 has an injection portion 21 and an abutment portion 22.

[0042] [Injection part] The spray unit 21 is connected to a valve stem 11a (spray valve 11) from inside the cap 20, and sprays the coolant R sprayed from the spray valve 11 to the outside. The coolant R is sprayed from a spray nozzle 21a of the spray unit 21. The spray unit 21 is provided with a diffusion space 21b, as necessary, where the coolant R sprayed from the spray nozzle 21a diffuses and vaporizes. When the diffusion space 21b is provided, the coolant R sprayed from the spray valve 11 is sprayed from the spray nozzle 21a of the spray unit 21, and then diffuses and vaporizes in the diffusion space 21b. This makes it easier for the coolant R to be evenly distributed over the contact part 22, which will be described later, and improves the cooling efficiency of the object to be cooled (for example, a textile product such as a towel).

[0043] [Contact part] The contact portion 22 is a member that contacts the cooling target to improve cooling performance. The contact portion 22 is positioned adjacent to the injection portion 21. Therefore, the coolant R sprayed from the injection portion 21 is immediately transferred to the contact portion 22. As a result, the coolant R spreads and contacts the cooling target in contact with the contact portion 22, instantly cooling the cooling target and even freezing it. Furthermore, the presence of the contact portion 22 prevents the coolant R sprayed from the injection portion 21 from excessively contacting the outside air, thereby suppressing temperature rise in the cooled or frozen portion and enabling efficient cooling of the cooling target. The contact portion 22 may have any shape. The shape of the contact portion 22 may be, for example, a round, square, floral, star, or animal pattern, or a character pattern such as alphabets, numbers, katakana, or hiragana. Since a frozen pattern is formed on the surface of the object to be cooled according to the shape of the contact portion 22, various frozen patterns can be formed on the object to be cooled by freely changing the shape of the contact portion 22. The cooling cylinder 100 of the present invention, which has such unique features, can provide added value that easily attracts people's attention. For example, if a user posts the cute frozen pattern formed on a towel or handkerchief on social media, it can provide entertainment that will entertain many people beyond the purpose of cooling.

[0044] The contact portion 22 preferably has annular cooling surfaces 22a and 22b arranged to surround the injection portion 21. In this embodiment, double annular cooling surfaces 22a and 22b are provided, but single or triple or more annular cooling surfaces may be provided. By providing the annular cooling surfaces 22a and 22b, the coolant R injected from the injection portion 21 penetrates between the annular cooling surfaces 22b and the cooling target, and further between the annular cooling surface 22a and the cooling target, thereby instantly and efficiently cooling the cooling target. Furthermore, because the annular cooling surfaces 22a and 22b are arranged to surround the injection portion 21, the annular cooling surfaces 22a and 22b firmly press the target area, and the coolant R injected from the injection portion 21 spreads evenly between the annular cooling surfaces 22a and 22b and the cooling target, thereby uniformly cooling the cooling target. In addition, when providing double annular cooling surfaces 22a and 22b as in this embodiment, if the width of the outer annular cooling surface 22a is made larger than the width of the inner annular cooling surface 22b, as shown in Figure 1, the posture of the cooling cylinder 100 during spraying is more likely to be stable.

[0045] In this way, the cooling cylinder 100 can efficiently and instantly cool the object to be cooled by the cooperation of the spray portion 21 and the annular cooling surfaces 22a and 22b (contact portion 22), making it easy to obtain a cooling item suitable for everyday use. Even if the object to be cooled is a textile product with a relatively large surface area, such as a towel, handkerchief, wet towel, tissue, mask, gauze, or clothing, the entire textile product can be cooled by pressing the cooling cylinder against the surface of the textile product multiple times or by sliding the cooling cylinder over the surface of the textile product. Furthermore, as will be explained in the cooling method described below, the cooling cylinder 100 can be used with simple operations, making it easy to use in everyday life.

[0046] <Cooling method using a cooling cylinder> Fig. 2 is a partial cross-sectional view showing the state (method) of use of a cooling cylinder 100 according to one embodiment of the present invention. (a) shows the state before the cooling agent is sprayed, (b) shows the state immediately after the cooling agent is sprayed, and (c) shows the state while the cooling agent is being sprayed. Fig. 3 is an explanatory diagram showing the formation of a frozen pattern on a cooling target using a cooling cylinder 100 according to one embodiment of the present invention. (a) shows the state of the surface of the cooling target before the cooling agent is sprayed, and (b) shows the state of the surface of the cooling target with the frozen pattern formed.

[0047] 2, the object to be cooled is a towel M. To cool the towel M, a user places the towel M on a flat table and places the cooling cylinder 100 on top of the towel M in an inverted position (placing step). At this time, as shown in FIG. 2(a), the annular cooling surfaces 22a and 22b (contact portion 22) of the cap 20 contact the surface of the towel M, and the nozzle 21a is directed toward the surface of the towel M.

[0048] Next, the user presses the cooling cylinder 100 against the towel M (pressing step). The pressing time of the cooling cylinder 100 is preferably 0.1 seconds or more. At this time, the cap 20 presses the injection valve 11 of the pressure-resistant container 10 due to the reaction force, and the valve mechanism inside the pressure-resistant container 10 is activated, causing the coolant R to be ejected from the valve stem 11a. The coolant R ejected from the valve stem 11a is ejected from the injection port 21a of the cap 20, and is diffused and vaporized in the diffusion space 21b as shown in FIG. 2(b).

[0049] Furthermore, the cooling canister 100 is maintained in a state of being pressed against the towel M (maintenance step). Then, as shown in FIG. 2(c), the cooling agent R enters between the annular cooling surfaces 22a and 22b and the towel M, permeates the towel M, and instantaneously cools the towel M. Here, the cooling canister 100 may be slid along the surface of the towel M while being pressed against the towel M. In this case, a wide area of ​​the towel M can be cooled with a single operation.

[0050] The above-mentioned maintaining step may be carried out until the towel M is frozen. The frozen towel M can maintain a high cooling effect and is suitable for use during the recent hot summer months. The present invention also has a great advantage in that a high cooling effect can be easily obtained and the object to be cooled can be frozen without the need for facilities or equipment such as a freezer.

[0051] Once the coolant R has been sufficiently distributed over the towel M, the user lifts the cooling canister 100 (lifting step) as shown in Fig. 3(a) to Fig. 3(b). This stops the spray of the coolant R from the cooling canister 100, and the cooling of the towel M is completed. At this time, as shown in Fig. 3(b), a frozen pattern is formed on the surface of the towel M according to the shape of the annular cooling surfaces 22a and 22b (contact portion 22) (in this embodiment, the portions corresponding to the annular cooling surfaces 22a and 22b are slightly raised, and the portion corresponding to the diffusion space 21b is raised). If the towel M needs to be cooled again or if a different portion of the towel M needs to be cooled, the states (operations) shown in Figs. 2(a) to 2(c) can be repeated.

[0052] As described above, the cooling method using the cooling cylinder 100 of the present invention can be carried out by simply performing the simple steps of placing, pressing, maintaining, and lifting.

[0053] According to the cooling method of the present invention, the cooling cylinder 100 can be used in an inverted state with the cap 20 facing downward, which allows the user to work in a more comfortable posture, particularly when cooling a relatively large textile product such as a towel M. Therefore, the cooling cylinder 100 is not only superior in cooling efficiency compared to conventional cooling aerosols, but is also easy to use. [Industrial Applicability]

[0054] The cooling cylinder and cooling method of the present invention are used for the purpose of cooling textile products, and are primarily intended to cool daily necessities and sanitary products, but can also be used for cooling clothing products. Furthermore, if ingredients used in cosmetics are enclosed in the cooling cylinder together with the cooling agent, it can also be used as a cosmetic product. [Explanation of symbols]
