Abstract

A packsack or bag floating and carrying structure contains cloth with an inner layer made of thermoplastic material, an airtight zipper with the thermoplastic material arranged on the surface and a one-way air inlet valve set made of the thermoplastic material. Side corners where the packsack or the bag is formed conduct high frequency heat seal welding to the plastic material of the inner layer of the cloth, so as to form the packsack or bag shape; at a pre-opening position of the packsack or bag, high frequency heat seal welding is conducted on the airtight zipper, and at a position on the packsack of the bag where the zipper is not located, high frequency heat seal welding is conducted on the one-way air inlet valve, so that air can be filled into the packsack or the bag from outside. The carried object can be arranged in the floating object. When the displacement of such packsack or bag being sealed and filled with air is more than the weight of the carried object, not only floating and carrying of objects can be realized on water, but also the lifesaving function can be achieved.

Description

The bag of waterproof and floatability loading or bag

Technical field

The utility model relates to a kind of waterproof and structure that can the floating on water surface loading.Especially relate to a kind of knapsack or sack, both can daily loading, again can loading waterborne and have the lifesaving function concurrently.

Background technology:

General knapsack or sack mostly are that cloth is a raw material, make with sewing machine to form.Rainwater is easy to see through the stitching pin hole and is penetrated in bag or the bag when the rainy day, causes the moist immersion of object in the bag.The waterproof bag has also appearred in recent years, a kind of knapsack or bag configuration are for example disclosed among the CN2712136Y, its structure mainly comprises cloth material top layer and bonding plastic cement nexine, plastic cement bound edge and cloth material bound edge, plastic cement bound edge and plastic cement nexine edge weld, therefore wrapping periphery does not have the slit, well waterproof.For this Knapsack structure,, can Sometimes When It Rains facilitate just as the daily use of common knapsack.But during for field work or outdoor travel and military operation, if knapsack only has the dress thing and water-proof function is not enough.Wade across a river or during floating marine at needs, perhaps fall into water accidentally or meet by chance under some fortuitous event such as flood, at this moment need knapsack to have the floating function of rescue concurrently usually.And in this case, this common waterproof knapsack or sack sink because of heavy burden in water, can not reach the function of floating on water surface loading and lifesaving at all.

The utility model content:

The utility model purpose provides a kind of knapsack or sack, except having water-proof function, can also the floating on water surface loading and can reach the structure of lifesaving function, and reach not only practicality but also multi-functional effect is arranged.

Product of the present invention can be achieved through the following technical solutions.

The utility model provides a kind of knapsack or the floating loading structure of sack, include: the cloth that thermoplasticity material nexine is arranged, there is the air hermetic slide fastener of thermoplasticity material on the surface, the breather cheek valve group that the thermoplasticity material is made, it is characterized in that, at the edge that forms described knapsack or sack with the plastic material of described cloth nexine by the high frequency heat seal welding, to form knapsack or sack body, pre-open position at described knapsack or sack, the described air hermetic slide fastener of high frequency heat seal welding, at the place, non-slide fastener place of described knapsack or sack, the described breather cheek valve of high frequency heat seal welding makes and can inflate in knapsack or sack from the external world.

The specific embodiment

Structure of the present utility model and special efficacy thereof further are described in more detail as follows according to the most preferred embodiment shown in Fig. 1-4:

Wherein, so-called thermoplastic plastic is meant multiple thermoplastic plastics such as PVC, TPU.Shown in Fig. 1-4, knapsack of the present utility model or sack structure consists predominantly of the plastic with plasticity nexine 2 bonding with cloth 1, the air hermetic slide fastener 4 of surperficial adhesion heat plastic with plasticity 3, and the breather cheek valve 5 made of thermoplastic plastic.Cloth 1 utilizes high frequency heat seal to be fused into knapsack or sack shape together with bonding with it plastic with plasticity nexine 2, with air hermetic slide fastener 4 weldings of surperficial adhesion heat plastic with plasticity 3 at the suitable opening place, at the appropriate location of knapsack or sack welding intake valve 5.Can form the air bag of an inflatable seal by intake valve 5 inflations in case of necessity, reach the function of floating on water surface loading.

Claims

1. the bag of waterproof and floatability loading or bag, include: the cloth (1) that thermoplasticity material nexine (2) is arranged, there is the air hermetic slide fastener (4) of thermoplasticity material (3) on the surface, the breather cheek valve group (5) that the thermoplasticity material is made, it is characterized in that, at the edge that forms described knapsack or sack with the plastic material of described cloth nexine (2) by the high frequency heat seal welding, to form knapsack or sack body, pre-open position at described knapsack or sack, the described air hermetic slide fastener of high frequency heat seal welding (4), place, non-slide fastener place at described knapsack or sack, the described breather cheek valve group of high frequency heat seal welding (5) makes and can inflate in knapsack or sack from the external world.

2. the bag of waterproof according to claim 1 and floatability loading or bag is characterized in that described thermoplastic plastic is PVC, TPU.
