Description

[Detailed Description of the Invention] The present invention relates to a packing device for eaves gutters, and more specifically, the tongue piece 2 extends from one side of the open end of the longitudinal end of a cylindrical cardboard case body 1 with a square cross section. At the same time, flap pieces 3 are extended from the remaining three sides of the opening end in the longitudinal direction of the cardboard case body 1, and an eave gutter 4 having a semicircular or semicircular cross section is formed.
Place the stacked pieces into the cardboard case main body 1 so that the open side of the eaves gutter 4 in the longitudinal direction faces the side piece 5 from which the tongue piece 2 of the cardboard case main body 1 extends, and then Place it on the left and right side pieces 6 of the cardboard case body 1, bend the tongue piece 2 at right angles to form the first folded piece 7, and insert the tip of the first folded piece 7 inward along the first folded piece 7. Fold it back to form the second bent piece 8, and attach the tip of the second new piece 8 to the tongue piece 2.
is newly bent along the extended side piece 5 to form a third bent piece 9,
This third bent piece 9 is inserted into the eaves gutter 4 at the end facing the side piece 5 from which the tongue piece 2 extends, and both ends of the third bent piece 9 are brought into contact with the in-plane side surface of the eaves gutter 4. At the same time, the second bent piece 8 is applied to the longitudinal end of the eaves gutter 4, and the three flap pieces 3 are bent to close the opening at the longitudinal end of the cardboard case body 1. This is related.

Conventionally, when the eaves troughs 4' are stacked and packed by being inserted into the cardboard case body 1', there has been a drawback that the eaves troughs 4' located at the ends are deformed inward as indicated by the arrows in FIG.

For this reason, as shown in Figure 2, there are holes 1 in the ears 1 and 0' of the eaves gutter
1', a metal rod 12' bent into a U-shape is inserted into the ear part 10' to prevent deformation of the eaves gutter 4', or as shown in Fig. 3, the opening of the eaves gutter 4' is Four strips 13 on the circumferential surface
'', a flat cardboard paper 14' is inserted to prevent the eaves gutter 4' from deforming.

However, the one in Figure 2 can only be used with a hole 11' in the ear 10', and the one in Figure 3 can only be used with a groove 13'.
It could only be used for things with ''.

Furthermore, in both the cases shown in FIGS. 2 and 3, a metal rod 12' and a flat cardboard paper 14' must be prepared separately from the cardboard case body 1', resulting in an increase in cost.

The present invention was devised in view of the above-mentioned conventional drawbacks, and its purpose is to provide a tongue piece on the cardboard case body so that the tongue piece can prevent the deformation of the eaves gutter. The number of parts can be reduced, and by placing the second folded piece of the tongue against the longitudinal end of the eaves gutter, the second folded piece and the first folded piece overlapping it can be used to close the opening. To provide a packing device for an eaves gutter which can double as a closing flap piece and can ensure packing.

The present invention will be explained in detail below with reference to Examples.

In the figure, reference numeral 1 denotes a cylindrical cardboard case body with a square cross section, in which a tongue piece 2 extends from one side of the open end in the longitudinal direction, and a flap piece 3 extends from the other three sides.

FIG. 7 shows this developed view.

Reference numeral 15 in FIG. 7 is an overlapping piece, and when forming a cylinder with a rectangular cross section, this overlapping piece 15 is overlapped with the opposite side piece 16 and fixed with adhesive or a fastener such as a stapler. ing.

The tongue piece 2 is bent along the first bending line 17 so that the tongue piece 2 is bent at a distance of + of the protruding length of the tongue piece 2 from the protruding base of the tongue piece 2. A second bending line 18 is formed.

That is, the tongue pieces 2 are arranged in order from the protruding base side to the first bent piece B and the second bent piece.
Folded piece 8. Although it is the third bent piece 9, the first bent piece 7
The lengths of the second bent piece 8 are t and t, respectively, when the length of the protruding piece 2 is l, and the length of the third bent piece 9 is the same.

The width of the side piece 5 extending the tongue piece 2 and the width of the side piece 5 overlapping with the overlapping piece 15 and the maximum middle of the eaves gutter 4 are the same length L, and the third bent piece 9 The width and the maximum opening width of the opening of the eaves gutter 4 are the same length W, respectively.

Furthermore, the protruding lengths of the tongue piece 2 and the three flap pieces 3 are equal;
Each flap piece 3 may be provided with a bending line 19 so that it can be bent at the edge.

Therefore, the tongue piece 2 is formed by stacking the eaves troughs 4 each having a semicircular or cross-sectional shape, and is opened in the longitudinal direction of the eave troughs 4.
Insert the cardboard case body 1 so that it faces the side piece 5 that extends.
inside, and both ends of the eave gutter 4 (i.e., the outer surface of the ear part 10)
are applied to the left and right side pieces 6 of the cardboard case body 1 to prevent the stacked eaves gutters 4 from expanding outward.

The tongue piece 2 is bent inward at a right angle at the protruding base, further bent by 180° at the first bending line 17 to align the first bending piece 7 and the second bending piece 8, and then folded into the second fold. Bend the third bent piece 9 by 90° at the bending line 18, align the third bent piece 9 with the inner surface of the side piece 5 from which the tongue piece 2 extends, and insert the third bent piece 9 into the eaves gutter 4. Both ends of the curved piece 9 are placed against the in-plane side surfaces of the opening of the eaves gutter 4, and the second bent piece 8, which is folded back along the first bent piece 7, is placed against the longitudinal end surface of the eaves gutter 4. The two flap pieces 3 are bent to close the longitudinal end opening of the cardboard case body 1.

In this way, the openings at both ends of the cardboard body 1 are closed, and the flap pieces 3 are fixed with adhesive or a fastener such as a stapler.

In the present invention, as described above, a tongue piece is extended from one side of the opening end in the longitudinal direction of the corrugated cardboard body, and the third bent piece, which is the tip of this tongue piece, is inserted into the eaves gutter. Since the end touches the inner surface of the eaves gutter, the tongue piece provided on the cardboard case body can prevent the eaves gutter from deforming inward when packed, unlike conventional deformation prevention devices that are separate from the cardboard case body. It is advantageous that there is no need to prepare special parts, the number of parts is small, the cost is low, and the work is easier.

Furthermore, even if there are no holes in the ears of the eaves gutters, there are holes that are not large enough to insert a metal rod, or there are no grooves into which cardboard can be inserted. Regardless of the conditions, any eaves gutter can be prevented from being deformed by the tongue piece, and since the tongue piece extends from the cardboard main body, the deformation can be reliably prevented without moving inside the eave gutter.

Furthermore, since both ends of the eaves gutter are brought into contact with the left and right side pieces of the cardboard main body, it is of course possible to prevent the eaves gutter from deforming outward.

Also, since the second bent piece is placed against the longitudinal end surface of the eaves gutter,
The tongue piece doubles as a flap piece, and in fact, in addition to the three flap pieces, this tongue piece serves as a fourth flap piece to reliably cover the end opening of the cardboard case body, and This ensures the protection of the ends of eaves gutters.
