[0002]
[Prior art]
In general, in the case of a product that is taken out of a packaging case and sold and displayed, it is often returned to the packaging case at the time of purchase and returned to the purchaser.
This type of product may be impaired in quality, such as dust, dirt, hand oil, etc., adhering to the product in the display state, or causing damage or damage to the product due to unexpected situations such as dropping. In order to avoid such a situation, in recent years, it has been practiced to store the air-tight airtight transparent packaging bag.
As shown in FIGS. 14 and 15, this type of packaging bag body AA is obtained by folding a flat-shaped binding bag 100 in which the entire periphery is heat-sealed and in a sealed state into two at a square central portion. The periphery is heat-sealed while leaving the opening 100A at one end, and air can be introduced into the binding bag 100 by the air valve 110. The introduced air is held by the air valve 110, and the inside of the binding bag is passed through the air valve 110. By inserting a straw or the like into the binding bag, the inside of the binding bag is communicated with the outside air so that the air in the bag can be removed (for example, see Patent Document 1).
As a usage of the packaging bag body AA, after inserting the product C from the opening 100A of the binding bag 100 into which air is not introduced, for example, air is blown from the air inlet 110a of the air valve 110 through the mouth to perform binding. The bag 100 is inflated, the product C is wrapped in the binding bag 100, and the fabric surface 100a of the binding bag 100 is brought into pressure contact with the surface of the product C, and an air layer 100b is formed around the product to form the product C. By preventing direct contact, it prevents dust, dirt, hand oil, etc. from adhering, and protects the product with a cushion layer, such as the air layer 100b, so as to actively avoid a situation in which the quality of the product is reduced. Is what you can do.

BEST MODE FOR CARRYING OUT THE INVENTION
[First Embodiment]
Hereinafter, a cylindrical bag A, which is an example of an embodiment to which the present invention is applied, will be described with reference to the drawings.
The tubular bag A of the present embodiment is obtained by applying the present invention to a display bag that is temporarily housed and held until a commodity C, which is a target article that is taken out of the packaging case and sold and displayed, is purchased. It is.
[0028]
As shown in FIGS. 1, 4 (a), 4 (b) and 4 (c), this cylindrical bag A is formed by folding the cylindrical body 1 into one end opening 1A of the cylindrical body 1 and folding the cylindrical body 1 into the other. An end opening 1B is arranged, and the edges of the openings 1A and 1B at one end and the other end are joined in an airtight state over the entire circumference of the openings 1A and 1B, so that the outer peripheral surface 1C and the inner peripheral surface 1D are connected to a continuous surface. A tubular bag A1 is formed, and the tubular bag A1 is provided with an air valve B having an air introducing means B1 and an air release preventing means B2.
[0029]
Further, in the tubular bag A of this embodiment, as shown in the drawing, the tubular bag body A1 is formed with a tubular outer diameter and a tubular length that can wrap the entire target product C. Here, the cylinder length is the outer diameter of the cylindrical body 1 and is larger than the maximum width of the target product. The length of the tube is approximately half the length of the tube 1 so that a tube corresponding to the size of the target product C can be manufactured.
[0030]
The tubular body 1 is formed of a transparent sheet-like soft material made of PP, PE, olefin resin or the like.
[0031]
As shown in FIGS. 1 and 4 (b), the air valve B includes a rectangular flat cylindrical air introduction passage Bc having both ends opened, and one end opening 1A of the cylindrical bag body A1 and other parts. One end Ba is extended to the outside with the joining portion 1E of the end opening 1B as a boundary, and the other end Bb excluding the one end Ba is provided on the inner side in a state of being accommodated. By injecting air into the air introduction passage Bc and introducing the air into the cylindrical bag A1, the air introducing means B1 capable of inflating the cylindrical bag A1 is constituted. Due to the pressure difference between the inside and outside of the tubular bag A1, the flat cylindrical air introduction passage Bc portion in the tubular bag A1 is closed in a tight contact state to produce a valve function, and the air is introduced into the tubular bag A1. It constitutes an air escape preventing means B2 that can prevent the outflow of air. Further, in this embodiment, one end side of the air valve B extending to the outside from the tubular bag body A1 is formed in a state where the tubular body is divided at the facing portion, and one end opening 1A of the tubular bag body A1 and the other end. The entrance of the air introduction passage Bc is formed at the joint 1E of the end opening 1B.
[0032]
Next, a method for manufacturing the cylindrical bag A will be described.
First, as shown in FIG. 4A, a tubular body 1 having a set cylinder outer diameter is formed by an extruder or the like, and cut into a set tube length.
[0033]
Then, as shown in FIG. 4 (b), the other end opening is folded back inside the one end opening 1A of the cylindrical body 1 and the junction 1E between the one end opening 1A and the other end opening 1B is bounded. And the edges of the openings 1A, 1B at one end and the other end are joined in an air-tight manner through the fusion means over the entire circumference of the openings 1A, 1B. An outer peripheral surface 1C and an inner peripheral surface 1D form a cylindrical bag A1 having a continuous surface. Here, the air valve B has a joint portion 1E between the one end opening 1A and the other end opening 1B of the cylindrical bag body A1 at a valve portion corresponding to a boundary position. An unfused material Bd is applied, and the edges of the openings 1A and 1B at one end and the other end of the cylindrical body 1 and the opening edges at one end and the other end of the cylindrical body 1 and the air valve B are fused. However, the inner peripheral surface of the flat cylindrical portion constituting the air valve B is not fused, and the inlet Bca of the air introduction passage Bc is formed.
[0034]
With this configuration, as shown in FIGS. 2 and 3, air is introduced into the tubular bag A1 from the air valve B to appropriately inflate the tubular bag A1, thereby providing an outer peripheral surface. 1C and the inner peripheral surface 1D are continuous, and the cylindrical bag A which forms the cylindrical air layer 1F inside can be formed.
[0035]
In the inflated cylindrical bag A, the outer peripheral surface 1C around the entrance corresponding to the insertion side shifts to the inner peripheral surface 1D as the target product C is inserted from one of the cylindrical entrances formed at both ends. When the bag C moves, the product C can be easily inserted into the inside of the cylinder, and in the storage position, the product C can be brought into a holding state in which the entire product C is surrounded by the inner peripheral surface 1D. From this state, the entrance of one end of the cylindrical bag body A1 is pressed so that the outer peripheral surface 1C around the entrance on the pressing side becomes the inner peripheral surface 1D, thereby causing the bag surface to move. C can be easily taken out from the entrance on the anti-pressing side.
[0036]
The air layer 1F of the tubular bag A is compressed by the inserted product C, so that the inner peripheral surface 1C can be brought into close contact with the inserted product C, and a cushioning property is formed on the entire bag. Thus, the product C in the bag can be protected against an unexpected situation such as a fall or a collision.
[0037]
Furthermore, in the unused state in which the air in the cylindrical bag A is not introduced, a flat bag state without bulk can be obtained.
[0038]
Further, by inserting a straw into the inflated tubular bag A through the air valve B, the internal air of the tubular bag body A1 is discharged to the outside through the straw, and the original flat bag state can be returned.
[0039]
In this embodiment, the example using the air valve B having the air introducing means B1 and the air retaining means B2 has been described. However, the present invention is not limited to this. There is provided an air introducing means comprising an air introducing hole by removing the stopper and adopting a plug which is detachable from the air introducing hole, and an air retaining means comprising a plug inserted into the air introducing hole. It may be one using an air in / out structure.
