Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a bag having a shock-absorbing bag surface.

[0002]

[Prior art]

 BACKGROUND ART Heretofore, a bag in which an inflatable bladder is arranged around or inside a bag has been disclosed as a bag capable of absorbing an external impact of a contained object.

Since such a bag can have a cushioning effect while maintaining its light weight, and can inject air into the air bag as needed to have a cushioning effect, it is not used. When used, it can be folded small and stored.

[0004]

[Problems to be solved by the device]

 However, the air bag is apt to release air even if it has a few holes or gaps, and it is difficult to maintain its shape and cushion. In addition, it is difficult to uniformly expand the entire body, and it is weak against external force such as piercing, and weak against partial impact. Therefore, the inventor of the present invention can provide cushioning properties even without injecting air, and can also take advantage of the lightness and cushioning properties of air, and is lightweight and uniform except for the drawbacks of air bags. In order to form a bag that can be expanded dynamically and is resistant to partial impact, an elastic material such as polyurethane is interposed between the airtight coatings, and these laminated bodies are fixed and fixed at appropriate intervals. An air bag containing elastic material was used between the parts, and a hollow communication path was used to connect the air bags to each other, and a bag with a cushioning property was developed by the cooperation of the elastic body and air.

According to this bag, it is possible to obtain a cushioning effect without injecting air into the air bag while surely maintaining the lightweight property, and further injecting air can further obtain a cushioning effect, so that the bag is always stable. As a result, a reliable buffering effect can be obtained.

However, since this bag is one in which an elastic body is encapsulated by a film having airtightness and then the peripheral portion is adhered, the surface from the surface encapsulating the elastic body to the adhered adhered portion is It was found that a slight wrinkle is likely to occur in the changed portion, and that air leakage may occur through this wrinkle over time if the air injection state is maintained. Also, when accommodating a photographic device, a camera, etc., the bag surface should be uneven so as to absorb the unevenness, especially when the lens part is thickly protected by a cushioning mechanism or the unevenness is accommodated. It is desirable to be able to form it.

Therefore, the inventor of the present invention has made the present invention by further improving the bag according to the above-mentioned invention. The purpose of the present inventor is to maintain a lightweight and stable cushioning effect. Therefore, even if it is used for a long period of time, it does not leak air, and even if it is a specially shaped storage item with irregularities such as a camera, a camera or other objects, it should be stored appropriately. The purpose is to provide a bag that can be used.

[0008]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a bag having an inflatable / contractible cushioning surface on a peripheral surface portion, the peripheral surface portion having at least a front material and a lining material, and at least one of them. A bag-shaped part is formed by forming an openable and closable opening on one surface, while an elastic body such as a flat-plate open-cell foam material is enclosed between the airtight front and back coatings to seal the periphery. Then, an air injection / exhaust mechanism was provided at an arbitrary position of this sealed bag to form a buffer bag body, and the buffer bag body was housed in the bag-shaped portion to serve as a buffer surface to form a bag. It is characterized by.

In addition, according to the present invention, the cushioning bag body includes an elastic body such as a flat-plate-like open-cell foam material between air-tight front and back coatings to seal the periphery, and the elastic body surface and front and back coatings. The inner surface of the bag is adhered to the bag, and an air injection / exhaust mechanism is provided at an arbitrary position of the sealed bag, and the buffer bag is housed in the bag-shaped portion to serve as a buffer surface to form a bag. Is also featured. In any of the above cases, the bag peripheral surface portion accommodating the buffer bag body may be appropriately bent and folded, and uneven portions may be formed in each portion depending on the difference in folding thickness.

[0010]

[Action]

 Even without forming multiple protruding air bags on the outer periphery of the bag, the cushioning bag can be detachably accommodated between the front and back to provide cushioning, and the inside and outside of the front and back are airtight. Even if it is not in the state, the buffer bag can surely maintain the airtightness. By adhering the front and back coatings to the elastic body, the buffer bag can be inflated uniformly by the injected air together with the elastic body.

[0020]

[Effect of device]

 In this way, an elastic body such as an open-cell foam material is interposed between the front and back coatings, and further these are adhered to form a buffer bag, which is sealed inside. Since the bag was formed with the bag material that was inserted in the bag, not only can it be made to have a shock-absorbing property even when air is not injected, but it also does not bulge locally by injecting air, and It does not bulge unevenly, it bulges in a uniform plate shape, and the elastic body expands by filling with air, and the air and elastic body work in an integrated state rather than in a separated state, so it is lightweight. However, it is possible to form a bag that exerts a strong cushioning property, has a constant shape and does not easily change due to external force, and exhibits a stable cushioning action without the fear of air leakage. Moreover, according to the bag material having the above-described structure, the bag material can be formed into an arbitrary shape and can be formed into a desired folded shape, so that the cushioning property of the desired surface can be strengthened or changed to form the bag, and Since both the inner and outer surfaces can be formed with the uneven surface depending on the material of the bag, it is easy to form a bag that wraps the stored items in a state of being in close contact with each other. Further, a gap can be intentionally formed between the folded pieces, and various shapes can be formed.
