Bag body

This creation is related to the bag body; in particular, it is a bag body with waterproof and moisture permeability characteristics.

Generally, the bag body that achieves the waterproof function is mostly realized by using a waterproof cloth (such as a plastic cloth) made of a petrochemical material to achieve waterproof and windproof effects by the high-density structure of the waterproof cloth.

However, the aforementioned waterproof fabric has limited plasticity, and it is difficult to make a diversified color design during manufacture, and the surface of the waterproof fabric is flat and smooth, and it is not easy to produce various changes on the surface, so that the waterproof fabric is made of the foregoing waterproof fabric. The shape and appearance of the bag is relatively monotonous.

In addition, the bag made of the waterproof fabric does not have the function of moisture permeability and venting. Therefore, in one case, it is assumed that the articles contained in the bag belong to fresh food such as vegetables and fruits. When the fresh food is continuously placed in a space that is not permeable to moisture and airtight, it is easier to accelerate the corruption rate of fresh food, and there is a lack.

Therefore, how to achieve the goal of moisture permeability and increased aesthetics under the waterproof effect is the design focus of today's waterproof bag body.

In view of this, the purpose of the present invention is to provide a bag body which, under the condition of being waterproof, also has the characteristics of being breathable, beautiful and selectively carrying articles.

In order to achieve the above object, the present invention provides a bag body for accommodating articles, characterized in that the bag body comprises an inner layer, an intermediate layer and an outer layer; wherein the inner layer is closer to the contained article than the outer layer And the inner layer is made of a material that can be combined with a felt of a devil's felt; the intermediate layer is located between the inner layer and the outer layer, and the intermediate layer is made of a waterproof and moisture permeable material; The inner layer is farther away from the contents contained therein.

The effect of the creation is that the water-permeable and moisture-permeable material of the intermediate layer can effectively resist the penetration of moisture outside the bag body, but the moisture inside the bag body can be effectively discharged to the outside without being stuffy; The inner layer can be used for the bonding of the object with the felt of the devil's felt, so that the user can place the object to adhere to a specific position in the bag body, and the user can store and retrieve and retrieve it again.

In order to explain the present invention more clearly, an embodiment will be described in detail with reference to the drawings. Referring to FIG. 1 to FIG. 3, the bag body 1 according to an embodiment of the present invention is configured to form an accommodating space for accommodating articles.

The inner layer 12 is located on the inner side of the bag body 1 and is made of a material having good gas permeability, and has moisture absorbing and gas permeable properties. In one embodiment, it can be supplemented with a material having soft properties. production. The inner layer 12 is closer to the article contained in the bag body 1 than the outer layer 16, and the inner layer 12 is made of a material that can be combined with a male felt mat. For example, the inner layer 12 is It can be made of felt fabric so that at least the unadhered side is fluffy and can be combined with the felt of the devil's felt.

The intermediate layer 14 is adhered between the inner layer 12 and the outer layer 16, and the intermediate layer 14 is made of a waterproof and moisture permeable material. In the embodiment, the intermediate layer is made of a material having a porous structure. For example, it is made of microporous expanded polytetrafluoroethylene (e-PTFE), but not limited thereto, wherein the surface of the intermediate layer 14 has a plurality of small pores, and the size of the pores It is smaller than water molecules (or water droplet molecules) but larger than water vapor molecules, whereby water vapor adsorbed by the inner layer 12 of the bag body 1 can pass through the pores of the intermediate layer 14 and be discharged outside the bag body 1. . Preferably, in one embodiment, the size (or diameter) of each of the pores is less than 100 micrometers but greater than 0.0004 micrometers, in order to obtain a better waterproof effect, and both have the dual function of gas permeability.

In addition, it is worth mentioning that the intermediate layer 14 is not limited to a material having a porous structure. In an embodiment, the intermediate layer 14 is capable of thermoplastic resin (TPU) non-porous hydrophilicity. The film is made of, but not limited to, the material property of the TPU, because the molecular interaction between the water molecules is strong, and the waterproof effect can not be achieved by the film, but in the bag The water molecules or water-gas molecules inside the body can be adsorbed by the hydrophilic functional groups of the TPU, and then diffused to the outside by the capillary phenomenon, thereby achieving the effect of waterproofing, moisture absorption and dehumidification.

The outer layer 16 has a gas permeable property, and the moisture adsorbed by the inner layer 12 can be discharged outside the bag body 1 through the pores of the intermediate layer 14 and the outer layer 16. Wherein, the outer layer 16 can be made of materials such as cotton, hemp, wool, silk, nylon, polyester fiber, etc. according to the design requirements of the pattern, the color and the outer surface texture, but in other embodiments The material is not limited to the above, and may be woven by a single material or a plurality of materials, so that the outer layer 16 which is exposed to the outside and has a display effect can achieve a multi-faceted aesthetic effect.

Therefore, through the design of the above-mentioned fabric structure 10, the bag body 1 of the present invention can be matched with a plurality of different cloth materials in appearance, and the bag of the present invention is compared with the bag body made of plastic cloth. The body 1 can have a relatively versatile appearance, and can be designed with a cloth of a touch that is preferred when the types of fabrics that are selectable are various.

It is worth mentioning that since the above-mentioned fabric structure 10 has the characteristics of moisture absorption and air permeability, the moisture of the articles placed in the bag body 1 can be effectively discharged outside the bag body 1 without being easily fresh food. A boring situation occurs and helps to preserve the item.

In addition, as shown in FIG. 4, since the inner layer 12 of the bag body 1 has the characteristics of being able to combine the male felt of the devil felt, the object 20 having the male felt 222 of the devil felt can be After being placed in the accommodating space of the bag body 1, the surface having the male felt 22 is detachably bonded to the surface 12a of the inner layer 12 of the bag body 1.
