Embodiment Construction

[0019] The following examples are used to further describe the present invention in detail, but do not limit the present invention in any form.

[0020] Such as figure 1 As shown, the high-tightness envelope of the present invention includes two parts, an upper envelope 1 and a lower envelope 2, both of which are flexible cubic covers made of high-barrier composite materials, and a floor mat 5 can be connected to the bottom of the lower envelope 2. A rainproof curtain 3 covering the sealing joint between the upper envelope and the lower envelope is arranged on the outer side of the lower edge of the upper envelope 1, and a temperature and humidity indicator 4 is also arranged on the upper envelope 1 to indicate the environmental conditions in the envelope.

[0021] Such as figure 2 As shown, the upper edge of the lower envelope 2 is provided with an eversion folded edge 6, and a zipper 7 for opening and closing is arranged between the outer edge of the eversion folded edge 6...

Abstract

The invention discloses a high-sealing-performance envelope which comprises an upper envelope and a lower envelope which are made of flexible material. The envelope is characterized in that an outward turned folding side is formed at the upper edge of the lower envelope; the lower edge of the upper envelope is separated from and connected with the folding side of the lower envelope through a zipper; a rain-proof curtain for covering the zipper is arranged on the outer side of the lower edge of the upper envelope; a sealing tape is adhered to the outer side of the zipper which is zipped up; and the upper envelope, the lower envelope, a ground mat and the rain-proof curtain are all made of high-barrier camouflage composite material. The envelope adopts a unique adhesive tape zipper type sealing structure design and high-performance preparation material, so that the envelope has the excellent properties of reasonable structure, good gas tightness, puncture resistance, tear resistance, high barrier, maintenance-free property and the like, can effectively solve the problem that army supplies are easy to become damp during long-term sealing, storage and transportation in the wild, and helps to improve the sealing, storage and transportation quality of the supplies.

Description

technical field [0001] The invention relates to an outer package for sealed articles, in particular to a highly airtight envelope used for moisture-proof storage and transportation of materials. Background technique [0002] Military equipment and materials are greatly affected by environmental temperature, humidity, light, and electromagnetism during storage and transportation. Especially in harsh environments, the properties of military materials will change to varying degrees, and some may even deteriorate or become invalid. For this reason, the staff will generally take certain protective measures when storing or transporting military equipment and materials to ensure the safe storage and transportation of materials. [0003] At present, there are many protection methods for military equipment and materials. The traditional method is to smear butter on military equipment such as firearms to isolate the materials from contact with the air, so as to prevent moisture and ru...
