Abstract

To provide a leather bag having a cooling and warming effect. [Solution] To provide a leather bag with heat and cold insulation, an inner bag made of heat and cold insulating fabric is placed inside the leather bag and secured with fasteners such as buttons and hook-and-loop fasteners. The outside of the inner bag (the surface that comes into contact with the leather) is covered with waterproof fabric to prevent moisture from reaching the leather. The heat and cold insulating inner bag can be removed by removing the fasteners, allowing it to be used in different situations. Furthermore, if the heat and cold insulating inner bag becomes damaged or soiled, it can be replaced.

Description

[Technical Field]

[0001] This invention relates to a leather bag (including synthetic leather, the same applies below) that has the effect of keeping things cool and warm. Summary of the Invention [Problem to be solved by the invention]

[0002] Conventional insulated bags have focused on functionality, with little emphasis on design or fashion. On the other hand, leather bags are luxurious and fashionable, but due to the characteristics of the material, they are not suitable for carrying items that become wet. In fact, no leather bags have been devised to provide the insulated function. [Means for solving the problem]

[0003] An inner bag made of insulating fabric is built into the leather bag and secured with fasteners such as buttons or hook-and-loop fasteners. The outside of the inner bag (the side that comes into contact with the leather) is covered with waterproof fabric to prevent moisture from reaching the leather. The inner bag can be removed by removing the fasteners, and when not in use as an insulating bag, it can be removed and used for different purposes depending on the situation. Furthermore, if the inner bag becomes damaged or soiled, it can be replaced. [Effects of the Invention]

[0004] There are several benefits to giving a high-quality, fashionable leather bag the ability to keep things cool and warm. For example, by being able to carry refrigerated items that get wet in a leather bag, it can be used as a formal work bag for documents, and also as a casual shopping bag for the supermarket or as a lunch bag. [Brief explanation of the drawings]

[0006] To make the leather bag and the inner cold / heat insulation bag detachable, hook-and-loop fasteners are attached to both the inner cold / heat insulation bag and the leather bag.

Claims

[Claim 1] The purpose of this invention is to provide a leather bag with a removable inner pouch for keeping things cool and warm.
