FIG. 3 is a perspective view showing an air inlet of a waterproof bag serving as a life tube according to the present invention, and FIG. 4 is a perspective view explaining an air inlet of a waterproof bag serving as a life tube according to the present invention.

Referring to FIGS. 1 to 4, the air inlet 30 is configured to allow air to flow into the first tube 10 and the second tube 20. As described above, the first tube 10 And the second tube 20, respectively.

3, the air inlet 30 is provided on the outer sides of the first tube 10 and the second tube 20, respectively, so that air is introduced into the first tube 10 and the second tube 20, And includes an injection port body 31 and a first plug 33 and a second plug 35 for injecting air or discharging air from the first tube 10 and the second tube 20.
The injection port body 31 is provided on the outside of the first tube 10 and the second tube 20 respectively and the first plug 33 extends from the injection port body 31 and the second plug 35 As shown in FIG. 4, has a hollow structure and is fixed to the connection portion between the injection port body 31 and the first stopper 33, and the backflow prevention means 37 is provided at the lower portion.
Specifically, the lower portion of the first stopper 33 is inserted into the upper portion of the second stopper 35, the lower portion of the second stopper 35 is inserted into the upper portion of the injection port body 31, Air is prevented from entering and exiting the second tube 20 and the air is injected into the first tube 10 and the second tube 20 through the second stopper 35 by opening the first stopper 33.
The backflow prevention means 37 provided in the second stopper 35 includes a backflow prevention plate 37a disposed at the lower portion of the second stopper 35 to form a bottom surface; A plurality of through holes 37b passing through the upper and lower surfaces of the backflow prevention plate 37a; When the air is injected from the upper portion of the second stopper 35, the second stopper 35 is elastically deformed to generate a gap with the through-hole 37b by the pressure of the air to be injected And the inner air of the first tube 10 and the second tube 20 flows out to the outside through the through hole 37b, And a backflow prevention pad 37c made of an elastic material that is elastically deformed to closely contact the through hole 37b and seal the through hole 37b.

Accordingly, when the user temporarily stops the infusion for re-breathing in the process of injecting air into the mouth, the air inside the tube is prevented from leaking, so that air can be efficiently injected.

In addition, when the air inside the tube is discharged to the outside, the air can be quickly discharged by separating the second stopper 35 from the injection port main body 31, and portability as a bag can be easily restored.

FIG. 5 is a perspective view illustrating an air infusion process of a waterproof bag serving as a life tube according to the present invention, and FIG. 6 is a perspective view showing a waterproof bag serving as a life tube together with a waterproof endothelium according to the present invention.

Referring to FIGS. 5 and 6, the waterproofing means 40 prevents water from flowing into the storage space when the present invention is used as an air tube for swimming or as a life tube, And a fastening collar 43 provided at both ends of the waterproof jacket 41 and the waterproof jacket 41 in the longitudinal direction.

The waterproof jacket 41 has a first jacket 41a provided at the product inlet / outlet A of the first tube 10 and a second jacket 41a provided at the second product outlet / The waterproof jacket 41 is folded in a state where the first outer skin 41a and the second outer skin 41b are overlapped with each other as shown in FIG. When the first tube 10 and the second tube 20 are inflated with air, the air pressure inside the tube strengthens the adhesion between the first shell 41a and the second shell 41b, The entrance A is sealed.

5B, since the article D such as a camera or a phone is fixed in the storage space due to bi-directional compression of the expanded first tube 10 and the second tube 20, So that the storage and waterproofing of the article can be stably maintained even when the shake due to swimming or the shock caused by disturbance of water occurs.

However, since the waterproof jacket 41 becomes circular when the fastening ring 43 is fastened, since wrinkles are formed in the first outer shell 41a or the second outer shell 41b disposed in the inner side in this process, The adhesion is reduced and leakage water may be introduced.

In order to prevent this, a core 45 for suppressing the generation of wrinkles may be further provided inside the waterproof jacket 41. The core 45 is made of a synthetic resin having flexibility, and the waterproof jacket 41, So that the occurrence of wrinkles in the circular deformation of the waterproof jacket 41 is suppressed.

6, in order to enhance the sealing property of the product inlet / outlet A, the first tube 10 and the second tube 10 constituting the product inlet / The inside of the second tube 20 may further include a waterproof inner skin 47 extending toward the bottom of the storage space. The waterproof inner layer 47 is made of a material having excellent adhesion to each other such as vinyl or latex and seals the water inlet 41 with the double-walled structure.

While the preferred embodiments of the present invention have been described, it should be understood that the scope of the present invention is not limited thereto and that the range of the present invention is substantially equivalent to the embodiments of the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
