Description

  The present invention relates to a bedding storage bag, and more particularly to a bedding storage bag in which bedding such as a futon, a blanket, a towelette, a sheet, and a pillow can be put in and out and the bedding outlet can be stopped with a hook.

  So-called beddings such as futons and blankets are usually distributed in a bedding storage bag made of a transparent or translucent synthetic resin film, and then distributed, stored, or displayed and sold in stores. The Bedding is a product that comes into direct contact with human skin at bedtime, so when examining the quality at the time of purchase, in addition to the appearance (for example, color and pattern), check the touch and elasticity, especially by touching them. It is required to obtain.

  The feeling of touch and elasticity of the bedding cannot be confirmed from the top of the bedding storage bag, or it is difficult to sufficiently confirm it. Usually, the bedding is taken out from the bedding outlet of the bedding storage bag and then touched with a finger. Or press to confirm. For this reason, it is preferable that the bedding storage bag has a structure in which a bedding insertion / removal port that allows the bedding to be taken in and out is provided in the bag body and the bedding insertion / removal port can be easily opened.

  In order to be able to open the bedding entrance / exit of the bedding storage bag, for example, it is necessary to provide an opening device such as a hook, a fastener, or an adhesive tape at the bedding entrance. Among various opening tools, hooks are widely used as opening devices for bedding storage bags because they require less installation space and are easy to open.

  FIG. 3 shows a perspective view of an example of a conventional bedding storage bag. The bag body 1 is made of a transparent synthetic resin film and has a total of six surfaces including an upper surface 2, a lower surface 3, a top surface 4, a bottom surface 5, a right side surface 6, and a left side surface 7. It is formed to have a substantially rectangular parallelepiped shape. The upper surface 2 further comprises two synthetic resin films, an upper surface 2a and an upper surface 2b, and the bedding can be taken out from the bedding outlet 8 between the upper surface 2a and the upper surface 2b, or the bedding can be put into the bedding outlet. Further, the upper surface 2a and the upper surface 2b are configured so that the overlapping portion 9 can overlap the end portion of the upper surface 2a on the end portion of the upper surface 2b.

  The upper surface 2 a and the upper surface 2 b are fastened to each other by a hook 10 and a hook 11 made of synthetic resin that form a pair of upper and lower surfaces. 4A is a cross-sectional view taken along line AA in FIG. The hook 10 includes a hook 10a and a hook 10b, and the upper surface 2a and the upper surface 2b of the bag body 1 can be held together by fitting the convex portion 13 of the hook 10b into the concave portion 12 of the hook 10a.

In order to fix the hook 10b to the hook 10a, for example, the upper surface 2a in the vicinity of the hook 10a and the upper surface 2b in the vicinity of the hook 10b are respectively picked with fingers, and the hook 10a and the hook 10b are pressed against each other. Therefore, during the fitting operation, a force that stretches the film is applied to the synthetic resin film on the upper surface 2a near the hook 10a and the upper surface 2b near the hook 10b when the hook 10a and the hook 10b are fitted.
On the other hand, in order to release the hook 10a and the hook 10b, the upper surface 2a in the vicinity of the hook 10a and the upper surface 2b in the vicinity of the hook 10b are respectively picked up with fingers, and the upper surface so as to separate the hook 10a and the hook 10b from each other. A tensile force is applied to the synthetic resin film 2a and the upper surface 2b. In general, it is considered that a greater force is applied to the synthetic resin film forming the bag body 1 when the stopper is removed than when the hook 10a and the hook 10b are fixed.

Therefore, when the hook 10a and the hook 10b are locked and / or released, especially when the hook 10a and the hook 10b are removed, the synthetic resin film near the hook 10a and / or the hook 10b is stretched and easily deformed.
In order to prevent the deformation, conventionally, the synthetic resin film on the upper surface 2a is folded inward at the folded portion 14, and similarly, the synthetic resin film on the upper surface 2b is folded inward at the folded portion 15, respectively. Thus, the thickness of the overlapping portion 9 is doubled over the entire periphery of the inlet / outlet 8 to increase the strength in the vicinity of the hooks 10a and 10b.

In the edge aligning portion 16 and the edge aligning portion 17 of FIG. 3, the upper surface 2a (folded back by the folded portion 14) is doubled, and the upper surface 2b (folded by the folded portion 15 is doubled). And the bottom surface 5 are laminated. FIG. 4B is a cross-sectional view taken along the line BB in FIG. 3 (along the central portion of the overlapping portion 9). In FIG. 4B, the end of the bottom surface 5,
The end portion (upper two layers) of the upper surface 2 a and the end portion (lower two layers) of the upper surface 2 b are laminated, and the upper and lower portions are further covered with a film 18, and stitched with a suture thread 19.
Since the edge aligning portion 16 and the edge aligning portion 17 are also portions where force is applied when the bedding insertion / removal port 8 is largely opened when the bedding is inserted / removed in the bag 1 of FIG. 3, the film 18 serves to reinforce this portion. It has also done.

However, the conventional bedding storage bag of FIG. 3 has the following problems.
1) The film 18 shown in FIG. 4 (B) is not provided at the folded end 20 and the folded end 21 shown in FIG. 4 (A). At the time of opening the bedding storage bag, a pulling force is applied to the periphery of the slot 8, particularly to the points 22 to 25 in FIG. 3, and the bag body 1 may be torn and damaged at the points 22 to 25. At the time of hook engagement and disengagement, the bonding strength at the location where tensile force was applied was not sufficient.
2) Since the entire end portion of the synthetic resin film on the upper surface 2a and the upper surface 2b corresponding to the entire periphery of the loading / unloading port 8 is folded back, the portion other than the vicinity of the portion where the hook is attached does not need to improve the strength. Thus, the synthetic resin film is overlapped twice until the synthetic resin film is wasted, and the appearance of the folded portion 14 and the folded portion 15 is not preferable.
3) As shown in FIG. 4 (A), an operation process for folding the synthetic resin film at the folding portion 14 and the folding portion 15 is required, and the work efficiency is lowered, and more synthetic resin film is required for the folding. Therefore, the production cost is increased particularly when producing in large quantities.

  The present invention is for solving the problems of the prior art, and the object of the present invention is not only to increase the strength of the bag body in the vicinity of the hook mounting location in the bedding storage bag, but also to fit the hook. Increases the tear strength of the peripheral edge bag body where the pulling force is applied when stopping and releasing, and compared with conventional bedding storage bags, when hooking in and out the bedding, the hook is locked and released. An object of the present invention is to provide a bedding storage bag in which damage and deformation of a bag body are difficult to occur, or the damage and deformation can be prevented.

That is, the bedding storage bag of the present invention is
Having a bedding out port, it comprises a bag body made of a synthetic resin film, and a Hamada' freely least one pair of polycarbonate hook attached to the bag,
The hook is made an end of Kigo synthetic resin film before forming the bedding out port is stopped overlapped with each other so vertically,
Near the location at which the hook is attached is in the range of about ambient 2~3cm of the synthetic resin film wherein the enhancing film of the same thickness of the same material as the hook, by being welded to the synthetic resin film, more thick Formed into meat ,
Periphery of at least the bedding and unloading opening of the bag, the non-woven fabric covering the end upper and lower front Kigo synthetic resin film, formed by the tear strength is enhanced by being sewn by the yarn, and characterized by Bedding storage bag.

Since the strength of the bedding storage bag according to the present invention is increased in the vicinity of the hook mounting portion, the bedding storage bag in the vicinity of the hook mounting portion can be prevented from being damaged and deformed when the hook is locked and unlocked. . Furthermore, since the bedding storage bag of the present invention has an increased tear strength at the peripheral edge of the bedding outlet, the bedding where a tensile force is applied when the hook is locked and unlocked when the bedding storage bag is opened. Breakage and deformation of the peripheral edge of the entrance / exit can be prevented.

FIG. 1 shows a perspective view of an example of the bedding storage bag of the present invention. The bag body 26 is made of a synthetic resin film. The synthetic resin film may be translucent or opaque in addition to being transparent. What can check the external appearance of the stored bedding easily visually is preferable.
As the synthetic resin film, a film made of low density polyethylene was used in the examples. As a material of the bag body 26, for example, polyolefin such as low density polyethylene, medium density polyethylene, high density polyethylene, polypropylene, polyester, polyamide, polyvinyl chloride, or the like can be used alone or in combination.
The thickness of the synthetic resin film is appropriately selected in consideration of the type of synthetic resin, the type and weight of the bedding to be stored, and the like.

The bag body 26 has a total of six surfaces including an upper surface 27, a lower surface 28, a top surface 29, a bottom surface 30, a right side surface 31, and a left side surface 32, and stores the bedding therein according to the size and shape of the stored bedding. In this state, the whole is formed in a substantially rectangular parallelepiped shape.
The upper surface 27 is further made of two synthetic resin films, an upper surface 27a and an upper surface 27b, and a bedding entrance 33 is provided between the upper surface 27a and the upper surface 27b. Further, the overlapping portion 34 is configured to be able to overlap the end portion of the upper surface 27a on the end portion of the upper surface 27b.
The width of the overlapping portion 34 can be appropriately selected according to the size and shape of the bag body 26 so that dust or the like outside the bag body 26 does not enter the inside of the bag body 26 from the bedding outlet 33. For example, it is 1 cm to 30 cm, for example, 3 cm to 10 cm.

  Various characters (for example, characters such as “... blankets”), figures, symbols, etc., which mean the kind of bedding stored in the bag body 26, the production area, etc. on any one or more surfaces of the bag body 26 A pattern, a sign, a registered trademark, or the like may be displayed in a desired color or a combination of a plurality of colors.

The upper surface 27a and the upper surface 27b are fastened to each other by a polycarbonate hook 35 and a hook 36 that form a pair of upper and lower surfaces.

  A reinforcing film 37 is welded to the vicinity of the portion where the hook 35 is attached, and a reinforcing film 38 is welded to the vicinity of the portion where the hook 36 is attached. The thickness is increased.

Enhancement films 37 and reinforcing films 38, can be welded to the surface and / or back surface of the upper surface 27a and upper surface 27b, for welding on the back side, the appearance of the bag body 26 preferably.
The reinforcing film 37 and the reinforcing film 38 having the same thickness and the same material as the synthetic resin film of the bag body 26 are welded in the range of about 2 to 3 cm around the hook 35 and the hook 36, and the thickness in the vicinity of the hook mounting portion is set. Doubled. Thereby, the strength is also doubled.

2A is a cross-sectional view taken along line AA in FIG. The polycarbonate hook 35 includes a polycarbonate hook 35a and a polycarbonate hook 35b. By fitting the convex portion 40 of the hook 35b into the concave portion 39 of the hook 35a, the upper surface 27a and the upper surface 27b of the bag body 26 are fitted. Can be stopped together. In the vicinity of the place where the hook 35a is attached, the reinforcing film 37 is welded to the lower side of the synthetic resin film on the upper surface 27a to improve the strength, and the reinforcing film 38 is welded to the lower side of the synthetic resin film on the upper surface 27b. The strength has been improved.
The end portion of the upper surface 27a (left side in the figure) is a non-woven fabric 41 is covered with upper and lower, tear strength is improved by being sutured suture 42. Similarly, the end portion (right side in the drawing) of the upper surface 27 a is covered with the nonwoven fabric 43 at the upper and lower portions and is sewn with the suture thread 44, so that the tear strength is improved.

FIG. 2B is a cross-sectional view of the side aligning portion 48 along the line BB in FIG. 1 (along the central portion of the overlapping portion 34). In FIG. 2B, the end of the lower surface 28, the end of the upper surface 27 a and the end of the upper surface 27 b are laminated, and the upper and lower portions are covered with a nonwoven fabric 45 and stitched with a suture thread 46.
In the side aligning portion 47 and the side aligning portion 48 of FIG. 1, the point 50 and the point 52 are formed by overlapping the nonwoven fabric 41, the upper surface 27b, and the lower surface 28, which are sewn covering the upper and lower portions of the bag body 27a, Further, the upper and lower portions are covered with a non-woven fabric 45 and are sewn with a suture thread 46. Point 49 and point 51 are
The non-woven fabric 43, the upper surface 27a, and the lower surface 28, which are sewn so as to cover the upper and lower portions of the synthetic resin of the bag body, are overlapped, and the upper and lower portions are further covered with the non-woven fabric 45 and are sewn with the suture thread 46. Therefore, the tear strength of points 49 to 52 is sufficiently improved. Accordingly, when the bedding is taken in and out of the bag body 26 in FIG. 1, the bedding outlet 23 is opened when the bedding is opened, and when the bag is opened, the vicinity of the hook is pinched and pulled to release the hook. Even if a tensile force is applied to the peripheral edge of 23, breakage and deformation do not occur in the portion of points 49 to 52 and the peripheral edge of the bedding outlet 23.
