AI Technical Summary
Existing cutlery designs fail to effectively cool the interior of food items, leading to discomfort when consuming hot foods, particularly for elderly individuals with impaired swallowing functions.
A metal spoon equipped with a coolant or ice pack on the handle that generates a cold temperature using latent heat of fusion, cooling the contact part through heat conduction.
The solution effectively cools the food surface and interior, enhancing ease of consumption and safety for elderly individuals with impaired swallowing functions.

Abstract
Description
[Technical Field]
[0001] This invention relates to cutlery that has a coolant or ice pack on the handle of a metal spoon or other cutlery. [Background technology]
[0002] Conventionally, when eating or drinking an object such as cooked food, the food is scooped up by contact with a spoon or other contact means having a spoon-shaped or other contact part, and then eaten or drunk while blowing on it to cool it down.
[0003] When eating or drinking cooked food such as porridge or rice porridge, people would scoop it up using a contact means such as a spoon with a spoon-shaped contact part, and then blow on it to cool it down before eating or drinking.
[0004] When elderly people who require nursing care and have reduced swallowing function eat or drink objects such as cooked food, including nursing care food that has been thickened to make it easier to swallow, they often use a contact device such as a spoon with a spoon-shaped contact part to scoop up the food, and then blow on it to cool it down before eating or drinking. [Patent documents] [Non-patent literature] Summary of the Invention [Problem to be solved by the invention]
[0005] When you blow on an object such as cooked food, only the surface cools, and the inside remains cool. As a result, it can be hotter than you expect when you put it in your mouth, making it difficult to eat or drink.
[0006] To provide cutlery that allows for easy eating and drinking of cooked food and other objects, and that contributes to safety when feeding or drinking to elderly people who require care due to their impaired swallowing function. [Means for solving the problem]
[0007] This device is composed of a structure in which a cold generator such as a coolant or ice pack that generates a cold temperature of approximately 0 degrees using a cold generating means such as latent heat of fusion is attached to the handle of a metal spoon or other object that has a spoon-shaped or other contact part that comes into contact with an object such as food by scooping or other contact means.
[0008] To use it, first place it in the freezer compartment of the refrigerator to freeze the cold generator, such as a coolant or ice pack attached to the handle, and then remove it when ready to use. When removed, the latent heat of fusion of the cold generator causes the coolant or ice pack to generate a cold temperature of approximately 0 degrees.
[0009] The cold temperature of approximately 0 degrees generated by the cold generator is conducted through the handle and other parts, cooling the contact parts such as the spoon-shaped part.
[0010] When the spoon-shaped contact part is brought into contact with an object such as porridge, miso soup, or a cooked food, for example, by scooping it up, heat is conducted and the object is cooled. [Effects of the Invention]
[0011] The cutlery of this invention can cool cooked foods such as porridge, miso soup, and nursing care meals, making them easier to eat and drink, and also contributes to safety when feeding or drinking to elderly people who require nursing care due to their impaired swallowing function. DETAILED DESCRIPTION OF THE INVENTION
[0012] The cutlery of the present invention will be specifically described below based on the best mode of carrying out the invention, with reference to the examples shown in the drawings, but the procedures and purposes of use are not particularly limited.
[0013] Fig. 1 is a plan view showing one embodiment of the present invention, and Fig. 2 is a front view showing one embodiment of the present invention. It is composed of a spoon-shaped contact part 1 that comes into contact with an object such as food by scooping or other contact means, a handle 3 extending from the contact part 1, and a cold generator 2 such as a coolant or ice pack attached to the handle 3 that generates a cold temperature of approximately 0 degrees using a cold generating means such as latent heat of fusion.
[0014] 3 is a cross-sectional view taken along the line AA of one embodiment of the present invention. The device is comprised of a spoon-shaped contact part 1 that comes into contact with an object such as food by scooping or other contact means, a handle 3 extending from the contact part 1, and a cold generator (exterior) 4 such as a coolant or ice pack that generates a cold temperature of approximately 0°C using a cold generating means such as latent heat of fusion, and a cold generator (solution) 5 attached to the handle 3.
[0015] The contact part 1 and the handle 3 are made of a suitable material such as metal. The cold generator 2 is made of a suitable material such as a coolant or ice pack, and is composed of a cold generator (solution) 5 made of a gel of water and a highly absorbent polymer, a water-absorbent polymer, an absorbent resin, sodium chloride, etc., and a cold generator (exterior) 4 made of a plastic material such as synthetic resin.
[0016] It is also desirable to provide a cover during use so that the hands holding the cold generator 2 do not feel cold. The outside of the cover should be made of an appropriate material such as cloth, chemical fiber, or synthetic resin, and the inside should be made of aluminum or other material with high cold retention properties. It is desirable to use a type that fits onto the cold generator 2 or a type that wraps around it so that the hands holding the cold generator 2 do not feel cold.
[0017] To use it, first place it in the freezer compartment of a refrigerator to freeze the cold generator 2. By keeping it frozen, when you take it out, the cold generator 2 generates a cold temperature of about 0 degrees due to the latent heat of fusion of the cold generating means, and the heat is conducted from the handle 3 to cool the contact part 1.
[0018] When the contact part 1 is brought into contact with an object such as porridge, miso soup, or cooked food such as nursing care food by a contact means such as scooping, heat is conducted and the food is cooled, making it easy to eat or drink, and also contributing to safety when feeding or drinking to elderly people who require nursing care due to their reduced swallowing function.
[0019] It is also desirable to have contact portions 1 in shapes other than spoon-shaped, such as fork-shaped or knife-shaped.
[0020] For example, when an object such as a cooked food such as a hamburger steak is brought into contact with the food by piercing it with the fork-shaped contact part and holding it down while cutting it with the knife-shaped contact part, heat is conducted and the food is cooled, making it easy to eat or drink, and also contributing to safety when feeding food or drink to elderly people who require care due to reduced swallowing function.
