We have continued to earnestly research the development of a lid with excellent water resistance. As a result, they have found that these problems can be solved by manufacturing the lid with a specific material and joining the lid and the box with a specific method, and have completed the present invention.

[0010] That is, the present invention is a lid for a box, which comprises a rectangular flat bottom portion and four side portions that are vertically upward in the periphery of the bottom portion. The lid material is made of thermoplastic resin. Molded hollow structure board with a thickness of 1-15 mm, thickness
It is a plate-like material selected from the group consisting of 0.5 to 7 mm water resistant paperboard, 0.1 to 7 mm thick plastic sheet, and 3 to 15 mm thick water resistant cardboard, and the lid is a square flat plate. It consists of the plate part and the side parts which are the four sides located almost vertically downward around the four peripheries of the top part, and the joint between the lid and the box is the side part of the box from the side part of the lid with the lid on the box. It is a lid for a box characterized by being driven by driving a stapler toward.

The material, shape, size, manufacturing method, joining method of the lid and the box, etc. of the lid of the present invention will be described below.
Here, when the present invention is described with reference to the drawings, what is shown is only an example relating to the lid of the present invention, and the present invention is not limited to what is shown. The material of the lid of the present invention is a hollow structure board having a thickness of 1 to 15 mm formed from a thermoplastic resin, a water resistant paperboard having a thickness of 0.5 to 7 mm, and a thickness of 0.1 to 7 mm.
Is a plate-like material selected from the group consisting of a plastic sheet and a water-resistant cardboard having a thickness of 3 to 15 mm.

Thickness from 1 to 15 mm molded from thermoplastic resin
The hollow structure plate is well known and is also called plastic corrugated cardboard, or abbreviated as Pradan in the industry, but as the hollow structure plate, Sumply (registered trademark), which is a hollow structure plate manufactured by Sumitomo Chemical Co., Ltd. ) And Sumipanel (registered trademark). These are hollow structure plates having a structure illustrated in FIG. 1, which are molded from a thermoplastic polypropylene resin, and are available in various thicknesses. An example of the water resistant paperboard having a thickness of 0.5 to 7 mm is, for example, Shicra Board (trade name) manufactured by Nippon Paper Industries Co., Ltd., and a plastic sheet having a thickness of 0.1 to 7 mm, such as a polyolefin-based material such as polyethylene or polypropylene. A sheet made of a resin (including a copolymer), a polyvinyl chloride resin, or the like can be used.
Water resistant corrugated cardboard with a thickness of 3 to 15 mm is a well-known plate material.

The lid of the present invention has a shape including a top plate portion 2 which is a rectangular flat plate, and side surface portions 3, 13, 23 which are four surfaces positioned substantially vertically downward around the four edges of the top plate portion 2. It is not limited in any other respect than that. An example of the lid of the present invention is shown in FIG. The lid 1 in FIG. 2 has a thickness of 4 mm.
Is a lid 1 manufactured from a hollow structure plate made of Sunply (trademark), and the parallel lines in the circles in the figure indicate the directions of the ribs of the hollow structure plate. The size of the lid 1 in FIG. 2 is, for example, the box 10 in FIG.
When used as a lid for 3, the vertical and horizontal sizes are sizes that can cover the box 103, and the height of the lid 1 may be arbitrarily selected within the height of the box 103. Top plate 2 of lid 1
The angle formed by the side portion 3 and the side surface portion 3 does not need to be an exact right angle, and a plurality of lids 1 can be inserted and stacked for storage in a compact state, such as paper cups stacked in the inserted state. It may be slightly larger than a right angle so that it can be transported or transported.

The lid 1 shown in FIG. 2 has a heat bar (for melting the portion of the dotted line A by heat) on the dotted line A of the template 4 which is cut out from a plate-like object into a predetermined size and a predetermined shape and is molded. It is manufactured by applying a heated rod-shaped jig), bending the part of the dotted line A by hand, for example, applying a heat bar on the dotted line B, and then bending the part of the dotted line B in the same direction. Obtain (hereinafter, the lid obtained by such a bending method is also referred to as "lid-1"). 2 is a lid 1
Since the portion of the line D of Fig. 3 is an integrated body obtained by bending the hollow structure plate, the portion where the cut portion of the hollow structure plate is close (the portion of the line C)
Even if it is not joined, the part of line D is not a one-piece lid (line D
This is a fixed lid with a shape that is less distorted by external force than a lid whose portion is cut (see later)). The portion of the line C may be fused and bonded by heat, for example.

Regarding the manufacture of the lid 1 shown in FIG. 2, it is preferable to fold the portion indicated by the dotted line A by the above-mentioned heat bar. However, regarding the bending of the portion indicated by the dotted line B, the bending direction of this portion and the rib direction of the hollow structure plate Since and are in the same direction, a method other than the heat bar may be used. For example, there is a method in which a U-shaped blade (the temperature of the blade is room temperature) is pressed against the portion of the dotted line B to form a U-shaped depression on the dotted line B, and it is bent by hand in the direction of the depression. Although the lid obtained by this bending method (hereinafter also referred to as “lid-2”) has a larger distortion with respect to external force than the lid-1, in joining the lid and the box, there are some inconveniences as described later. do not have.

The lid 1 shown in FIG. 2 has a rectangular top plate portion 2 and 4
A lid made of a template 4 which is an integral body obtained by cutting one plate-like object with one side surface 3 of a square, and a pair of opposed pair of templates 4 constituting the side surface of the lid. Surface (Fig. 2 (a)
The shape of the upper surface and the lower surface) is a trapezoid in which the length of the side on the top plate 2 side is longer than the length of the side on the lower side of the surface, and the other pair of opposite faces The shape of the left side surface and the right side surface of FIG. 2 (a) is a trapezoid in which the length of the side on the side of the top plate 2 is shorter than the length of the side on the lower side of the side. In the lid 1 manufactured by bending the template 4 along the dotted lines A and B, the remaining two non-parallel trapezoidal sides of the pair of opposed surfaces (the upper surface and the lower surface in FIG. 2 (a)) And the other pair of opposite faces (the left face and the right face in FIG. 2 (a)) of the trapezoid that are not parallel to each other are one example of a non-overlapping lid, each of which has four trapezoids. Is an example of a lid in which the angles formed by the longer one of the two parallel sides and the remaining two non-parallel sides of the trapezoid are all 45 degrees.

There are various modifications of the lid 1 shown in FIG. 2, all of which are included in the lid of the present invention. For example, for each of the four trapezoids, the angle formed by the longer side of the two parallel sides and the remaining two non-parallel sides of the trapezoid is not limited to 45 degrees. The angle may be greater than or less than 45 degrees, and if one trapezoid is focused, these two angles may or may not be the same. The maximum angle that the angle can take is less than 90 degrees (right angle). Further, the minimum angle that the angle can take is that the two lines C on the side surface of the lid are just one point at the lower end.
It is an angle of (overlapping) case, and in this case, the shape of the upper surface and the lower surface of FIG. 2 (a) is a triangle (not only an isosceles triangle). In the present invention, the meaning of the above-mentioned "trapezoid" includes the special case of such a triangle. The important point is that the portion of line D is a unitary body and the portion of line C does not overlap. It should be noted that it is sufficient to satisfy the condition that the portions of the line C do not overlap each other, and there may be some gaps.

Another example of the lid of the present invention is shown in FIG. FIG.
The lid 11 of is a lid manufactured from a hollow structure plate made of Sunply (registered trademark) having a thickness of 4 mm.
It is manufactured by bending like lid-1 and lid-2. The portion of the line E adjacent to the side surface portion 13 may be melt-bonded by, for example, heat (the lid in this case is hereinafter also referred to as “lid-3”) or may not be joined (in this case, The lid is hereinafter also referred to as "lid-4").

Still another example of the lid of the present invention is shown in FIG. The lid 21 in FIG. 4 is a lid manufactured from a hollow structure plate made of Sunply (registered trademark) having a thickness of 4 mm, and the dotted line portion of the template 22 can be bent in the same manner as in the case of lid-1 and lid-2. Manufactured by. The portion S where the side surface portion 23 overlaps may be joined by, for example, heat fusion or rivets (the lid 21 in this case is hereinafter also referred to as “lid-5”), or may not be joined (in this case, The lid 21 of the above is hereinafter also referred to as "lid-6").

Similar to the case of the above lid-1 to lid-6,
A plastic sheet having a thickness of 0.1 to 7 mm can be used to manufacture the lid of the present invention. The shape, size and manufacturing method of the lid of the present invention when the lid material is a water resistant paperboard having a thickness of 0.5 to 7 mm or a water resistant corrugated cardboard having a thickness of 3 to 15 mm are basically exemplified above. The same as those of the lid of the present invention. However, the place to fold the template made of these paperboards and corrugated cardboard is different from the case of the hollow structure board or plastic sheet molded from thermoplastic resin,
Can be bent without heating. For example, by pressing a V or U-shaped blade on the place where the template should be bent,
This is a method in which a V-shaped or U-shaped recess is provided on a template and the product is bent by hand in the direction of the recess.

The method of joining the lid of the present invention and the conventional box 103 illustrated in FIG. 6, for example, is a method using a stapler.
(Hereinafter also referred to as "stapler method"). FIG.
Shows the state in which the lid of the present invention and the conventional box 103 are joined by the stapler method. The mark ---- in the figure shows the joined state by the stapler, and the nails of the box are not shown. The procedure of the stapler method is to put an article in the box 103, cover the box 103 with the lid of the present invention, and then drive the stapler from the side portion of the lid toward the upper gusset of the box 103. In this case, if the angle between the top plate and the side surface of the lid is fixed (for example, lid-1, lid-
(3, lid-5), it is not necessary to press the side of the lid against the side of the box 103 by hand when driving the stapler, but the angle between the top and side of the lid is fixed. If not, that is, if the angle between the top plate portion and the side surface portion can be easily changed by an external force (for example, hand force) (for example, in the case of lid-2, lid-4, lid-6), and If the normal angle between the top plate and the side is larger than a right angle,
It is convenient to drive the stapler against the side 105 of the 103. When the material of the lid is a hollow structure plate, the stapler is preferably driven in a direction perpendicular to the ribs in order to strengthen the joint between the lid and the box.
