BACKGROUND OF THE INVENTION
The present invention relates to a plate-shaped packaging bag that covers and laminates laminated plate-shaped bodies as a unit.
[0002]
[Prior art and problems to be solved by the invention]
As a packaging bag containing a plurality of plate-shaped bodies having shape retaining properties, a sheet-shaped body is formed inside a bag formed by sealing the peripheral portion of a sheet member made of a polyolefin film, an aluminum staying film, or the like. The thing accommodated in the state which laminated | stacked was known.
[0003]
In order to take out the stacked plate-like bodies from the respective packaging bags, the sealing portion at the edge of the packaging bag is peeled off to form a take-off opening, or the packaging bag is torn at the play portion around the accommodated plate-like bodies. Or by cutting the plate-like material to form a take-out opening, and take out each plate-like body from the take-out openings at these ends.
[0004]
According to the conventional packaging bag, it is necessary to push the finger into the take-out opening formed at the end to pick out the plate-like body, and it is difficult to smoothly remove each plate-like body. In particular, when the stacked plate-like bodies are in close contact with each other or locked and it is difficult to slide in the plane direction, it is difficult to take out each plate-like body one by one.
[0005]
In addition, according to the conventional packaging bag, after opening the packaging bag, in order to prevent the remaining plate-like body from being taken out from the opening, the opened end can be folded or fastened with a clip or the like. It was inconvenient to handle because it was necessary to close it.
[0006]
An object of this invention is to provide the plate-shaped packaging bag which can take out the laminated plate-like material easily one by one, and is easy to handle after opening.
[0007]
[Means for Solving the Invention]
The plate-shaped packaging bag of the present invention is formed of various synthetic resin films, aluminum films, or sheet members such as paper, and has a cylindrical shape by sealing a pair of short sides of a rectangular sheet member to each other. And a laminated plate-shaped body having shape retaining property is inserted into the cylindrical sheet member, and an upper surface covering portion, a lower surface covering portion, and a side surface covering portion are provided on the cylindrical shape sheet member, and The two side opening portions are sealed as end seal portions while being wrapped so that the surplus portions of the side surface covering portions removed from the side surfaces of the plate-like body are folded inward, and are covered and packaged together. The plate-shaped packaging bag is formed on the upper surface of the laminated plate-like body with a length exceeding the total length of the plate-like body across the end seal portions on both sides, and at the center of the laminated plate-like body Is provided with an opening line formed so as to be opened by rotating the outer side sandwiching the opening line at a position that is 1/4 to 1/2 of the width of the plate-like body. Thus, a take-out opening is formed to take out the plate-like body. Since the side surface of the plate-like body is exposed when the formed extraction opening is expanded to the side of the plate-like body, each plate-like body can be easily taken out by grasping the exposed side end portion. Further, after the necessary number of plate-like bodies have been taken out, if the take-out opening is returned to the state before spreading to the side of the plate-like body, the take-out opening opens with a narrow width only on the upper surface of the plate-like body. Therefore, it is possible to easily prevent the remaining plate-like body from protruding from the take-out opening.
[0008]
The opening line in the above description is composed of, for example, a perforation, a part that is completely opened with a tack seal or the like, and facilitates manual tearing along the planned opening line. Further, the length exceeding the full length of the plate-like body on which the opening line is formed means a length exceeding the maximum projection width when the plate-like body is projected on a straight line perpendicular to the take-out direction, and the take-out direction Depending on the length.

The plate-like body packaging bag 10 of the present embodiment is formed by a sheet member made of a polyethylene film, covers and wraps a plurality of laminated plate-like bodies 11 together, and opens along a perforated opening line 22. The plate-like body 11 is taken out by opening.
[0010]
The plate-like body 11 is a disposable brush described in, for example, Japanese Patent Application No. 10-282690 relating to the application of the present applicant, and is formed using a non-woven fabric and has sufficient shape retention. Further, the plate-like body 11 is provided with uneven portions by projecting a large number of conical hollow projections 12 from the surface thereof. By these hollow protrusions 12, a concave portion is formed on the back surface of the plate-like body 11, and the back surface of the plate-like body 11 located above the hollow protrusion 12 on the surface of the plate-like body 11 located on the lower side. Ten or more plate-like bodies 11 are stacked while being inserted into the recesses, respectively, and have a height of about 30 mm as a whole.
[0011]
In order to package the plate-like body 11 with the plate-like body packaging bag 10, first, a pair of short side portions of a rectangular polyethylene film are sealed together as a short side seal portion 13 to form a cylindrical shape (FIG. 2). reference). The laminated plate-like body 11 is inserted into the cylindrical polyethylene film from the short side of the arc shape, and the short side seal portion 13 is arranged at the center of the lower surface of the plate. Next, both end openings of the cylindrical polyethylene film are sealed in a direction parallel to the front and back surfaces of the plate-like body 11 to form an end seal portion 21 (see FIG. 1). That is, by providing folding lines 14 along the upper and lower corners 20 of the side surface 19 of the long side portion of the laminated plate-like body 11, the upper surface covering portion 15, the lower surface covering portion 16, and the side surface covering are formed on the polyethylene film. The both-end seal portion 21 is formed while the excess portion 18 of the side surface covering portion 17 that is provided from the side surface 19 of the plate-like body 11 is bent and overlapped.
