Dry bag with clothing compression function

Abstract

The present invention provides a dry bag that allows for the waterproof storage of clothing and other items, and enables the manual removal of internal air without the use of tools to reduce the volume and compress the clothing. [Solution] The bag is characterized by comprising a bag body 1 made of a flexible waterproof material, a roll-top sealing section 2 that rolls up and seals the upper opening of the bag body, and an exhaust valve 3 disposed on the wall surface of the bag body, which has a check valve structure that expels internal air and prevents the inflow of fluid from the outside. The top of the waterproof fabric bag body is sealed with a roll-top, and internal air is expelled from the exhaust valve with a check valve provided at the bottom.

Description

Technical Field

[0001] The present invention relates to a dry bag that can store items such as clothes in a waterproof state and manually discharge the internal air to reduce the volume.

Background Art

[0002] Conventional dry bags are excellent in waterproof performance, but there is a problem that air easily remains inside the bag when closing the opening, and it bulges during packing. In addition, many general clothing compression bags require a suction tool such as a vacuum cleaner, lacking convenience.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The problem to be solved is to simply realize a structure that discharges the internal air and prevents water intrusion from the outside by simply crushing the dry bag itself without using a special tool.

Means for Solving the Problems

[0004] The present invention includes a bag body made of a flexible waterproof fabric, a roll-top sealing structure that rolls up and seals the opening, and an exhaust valve with a check valve provided at the bottom of the bag.

Effects of the Invention

[0005] According to the present invention, by manually pressing the bag after sealing the opening, the internal air is quickly discharged from the exhaust valve. Thereby, it can be carried while maintaining waterproof performance while minimizing the volume of the stored items.

Brief Description of the Drawings

[0006] [Figure 1] It is an external view showing the usage state of the clothing compression dry bag of the present invention. [Figure 2] It is an external view showing the exhaust valve with a check valve arranged at the bottom of the clothing compression dry bag. [Figure 3] The opening is rolled up. [Modes for carrying out the invention]

[0007] An embodiment of the clothing compression dry bag according to the present invention will be described with reference to the drawings. As shown in Figure 1, the dry bag mainly consists of a bag body (1) made of a flexible waterproof material and an exhaust valve (3) disposed at its lower part.

[0008] The bag body (1) is made of a material with a waterproof coating, which prevents water from entering from the outside and maintains airtightness inside.

[0009] The sealing section (2) seals the opening of the bag body (1) airtight and watertight by rolling it down multiple times (for example, three or more times) and connecting the buckles (4) provided at both ends. This protects the stored clothing from external moisture and water, and ensures airtightness during compression.

[0010] The exhaust valve (3) has a check valve structure that connects the inside and outside of the bag body (1). When the bag body (1) is compressed by hand with the sealing part (2) closed (in the direction of the arrow in Figure 1), the internal air pressure increases, and only the internal air is discharged to the outside through the exhaust valve (3). At the same time, water and air from the outside are blocked by the check valve of the exhaust valve (3).

[0011] According to this embodiment, the volume of the contents can be easily reduced simply by rolling up the bag itself or pressing down on it, without using external tools such as a vacuum cleaner. Furthermore, since it can be carried as a waterproof bag while maintaining its compressed state, it is possible to significantly improve packing efficiency during travel and outdoor activities.
