Description

[Detailed Description of the Invention] This invention relates to a lid fitting frame whose purpose is to assemble a lid abutting portion with relatively high strength against external forces from a single sheet of paper board.

Conventional lid insertion frames (hereinafter referred to as ten bats) are known to have a hollow square tube installed in the relatively deep inner corner of the lid, but those in which the square tubes around the four circumferences are not connected to each other, Since it has to be attached to the lid, it not only requires an extra step to attach it, but also has the problem that it is relatively easily deformed by external force because it is shaped like a rectangular tube.

However, this idea has an abutment plate connected to the four circumferences of the top plate via diagonal support plates, and an outer plate is also attached to the abutment plate, so it is significantly reinforced against external forces, and the inner side of the lid is By inserting it in a box shape, the shape of the tenbutt itself can be fixed, and the above-mentioned conventional problems have been solved.

That is, to explain the embodiment of this invention, the support plate 2.2a is stacked on the inside of the top plate 5a of the lid 5, and the support plate 2.2a rises obliquely inward through folds 7 on the four circumferences of the top plate 1.

2b and 2c are connected and the rising angle of the support plate is approximately 60 degrees)
, the support plate L 2 a92 be 2 c is bent outward through a fold 8 at its leading edge, and abutment plates L 3 a, 3 b, 3 c are connected to the top plate 1 in a horizontal direction. .

The contact plates 3, 3a, 3b, and 3c have creases 9 at their end edges.
Outer plate 4.4a bent at right angles to top plate 1 through
, 4b, 4c are arranged in series, and the outer plates 4.4a, 4b, 4c
The side walls of the support plates 2.2a, 2b,
Auxiliary plate 11.2c contacts the end edge of 2c, is bent through the fold line 10, and overlaps with the top plate 1. lla, llb, llc are installed in succession.

Abutment plates 3, 3a, 3 are provided at both ends of the support plates 2, 2b.
Notch 12t for b and 3c to form a frame shape and overlap each other
12at 12bt 12c are provided.

In the embodiment, the notches 12, 12b are formed on the support plate 2.
, 2b, but it goes without saying that it may be provided on the support plates 2a and 2C.

In addition, in the embodiment, the auxiliary plates 11.11a, ll
b, llc are provided, but the auxiliary plate is not an essential requirement and can be omitted if necessary.

(Embodiment in FIG. 5) As shown in FIG. 4, the insertion frame of this invention is inserted into the inside of the lid 5 and overlaps the waist top plate 1 and the top plate 5a of the lid 5, and the outer plates L 4at 4b of the insertion frame. , 4c are attached to the inner recessed circumferential side wall of the lid 5, but when it is inserted into the box 13, the contact plate 3 of the lid = 3 a, 3 bt
3c is brought into contact with the upper end surface of the side wall of the box 13, so that the depth at which the lid 5 is fitted into the box 13 can be regulated.

In this case, even if an external force is applied as indicated by the arrow 14 in FIG. 4, the outer plates 4, 4a, 4b.

4c support plates 2, 2a, 2bt 2c, and the contact plate 3 connected thereto? Since it is supported by 3at, 3bt, and 3c, there is no fear that the insertion frame will be deformed or crushed.

Furthermore, even if an external force as shown by the arrow 14a is applied from the lateral direction, since the support plates 2, 2a, 2b, and 2c are installed diagonally,
It has a reinforcing effect against external forces.

The depth of insertion of the lid 5 into the box 13 can be determined by regulating the width of the outer plate.

Further, the width of the abutting plate can be similarly set.

That is, according to this invention, a support plate, a contact plate, and an outer plate are successively arranged around the four circumferences of the top plate through creases, and these are folded and assembled into a box shape and inserted into the lid, so that a single paper board is formed. In addition, the support plate is provided diagonally as a fitting frame and connected to the abutment plate and the outer plate, so that the reinforcing effect is large and the abutment plate can be assembled from the box into which the lid is fitted. It comes into contact with the upper edge and has the effect of regulating the depth of fitting.

Furthermore, if the insertion frame of this invention is used, the outer plate is interposed between the support plate and the side wall of the lid, so sufficient shape retention can be achieved just by fitting it into the inside of the lid (no need for gluing). In addition, despite being assembled from a single sheet of paper, it forms a sturdy frame and has sufficient strength against external forces.
