AI Technical Summary
Conventional cooling hand towels provide only temporary relief in high-temperature environments, as the cooling sensation is short-lived due to the rapid evaporation of moisture or melting of ice.
A cool hand towel is designed by integrating a water-permeation-inhibiting membrane with towel fabric, forming a membrane pocket to store moisture, and incorporating a funnel-shaped ice block insertion structure to maintain a sustained cooling effect.
The towel achieves a long-lasting cooling sensation by storing moisture in the membrane pocket and releasing it as needed, while the funnel-shaped design ensures the ice block remains in place, prolonging the cooling effect.

Abstract
Description
[Technical field]
[0001] The present invention relates to a cool hand towel. [Background technology]
[0002] Conventional cold-feeling oshibori towels are generally made by wringing them out in ice water. There are also damp towels that are cooled in a refrigerator. Summary of the Invention [Problem to be solved by the invention]
[0003] During sports or physical labor in a high-temperature environment, sweating occurs as body temperature rises. Conventional cooling hand towels used in such situations include towels wrung out in ice water or damp towels cooled in a refrigerator, but the cooling sensation is temporary. The objective of the present invention is to provide a cooling hand towel that solves this problem and provides a sustained cooling sensation. [Means for solving the problem]
[0004] The cool hand towel of the present invention is prepared by combining a water-permeation-inhibiting membrane with towel fabric, sewing them together in the order of towel fabric, water-permeation-inhibiting membrane, water-permeation-inhibiting membrane, and towel fabric, forming a water-permeation-inhibiting membrane pocket and storing moisture in the water-permeation-inhibiting membrane pocket under gravity.
[0005] When a squeeze pressure is applied to the water-permeation-control membrane, the water stored in the water-permeation-control membrane pocket seeps out and moistens the outer terry cloth.
[0006] The upper opening of the cooling hand towel of the present invention is sewn together to form a funnel-shaped structure with a wide ice block insertion opening and a narrow ice block passage portion. Effect of the Invention
[0007] According to the first invention, When the ice block melts to an appropriate degree, moisture is stored in the water-permeability-restricting membrane pocket. When squeezing pressure is applied to the pocket, the stored moisture seeps out through the water-permeability-restricting membrane, making the outer terry cloth cool and moist. The remaining ice block remains inside, sustaining the cool sensation. When the ice block continues to melt and moisture is stored inside, squeezing pressure is applied, making the terry cloth cool and moist. By repeating this process, a long-lasting cooling sensation hand towel is obtained.
[0008] According to the second invention By making the ice block insertion port at the upper opening into a funnel-shaped structure, the inserted ice block is less likely to escape from the pocket of the cooling hand towel, thereby providing a cooling hand towel that lasts. [Brief description of the drawings]
[0009] [Figure 1] 1 is a plan view of a cool hand towel according to the present invention. [Diagram 2] 2 is a cross-sectional view taken along line AA in FIG. 1 in a state where no ice blocks have been inserted. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] Fig. 1 shows an example of a cooling hand towel (1) according to the present invention. Fig. 2 is a cross-sectional view taken along line AA in Fig. 1 when no ice blocks have been added, and shows the outline of the structure.
[0011] In Figures 1 and 2, the cooling hand towel (1) of the present invention is made of terry cloth (2) and a water-inhibiting membrane (3), and has a pocket-like shape with the bottom and left and right sides sewn together (4), and the upper opening (5) is sewn into a funnel shape (4) to form an ice block insertion section (5).
[0012] The water-restricting membrane (3) is made of a fabric or the like densely constructed of nylon fibers, polyester fibers, or the like, which is capable of storing water in the water-restricting membrane pockets (7) under gravity.
[0013] The basic method of using this invention is to put an appropriate amount of ice blocks into the upper opening (5) of the pocket, pass it through the ice block passage (6), and store the ice blocks in the water-permeability-restricting membrane pocket (7). When the ice blocks melt moderately over time and moisture is stored in the water-permeability-restricting membrane pocket (7), squeeze pressure is applied, causing moisture to seep out through the water-permeability-restricting membrane (3), making the terry cloth (2) cool and moist, and it can be used as a cooling hand towel (1). The same process is then repeated when the remaining ice blocks melt and moisture is stored in the water-permeability-restricting membrane pocket (7), and it can be used as a cooling hand towel (1).
