(Disadvantages of the prior art) Conventionally, two types of objects to be packed have the same planar shape as the other when one of them is reversed, for example, the abutting part forming the top plate of a planar L-shaped sink has a diagonal edge. When packing each of the top panel components, the direction of their diagonal edges is different, so it is not possible to pack them with packing sheets of the same shape.As a result, a packing sheet is made for each item to be packed, and Therefore, two types of items were each packaged. Therefore, it was extremely uneconomical.

(Means for solving the problems) This invention employs the following means to solve the above-mentioned drawbacks.

In the packing sheet 1 for packing a plate-shaped object 40 having a trapezoidal planar shape and having at least one of the non-parallel left and right edges being a diagonal edge 45, the packing sheet main body 2 having a rectangular planar shape has a top and a bottom. A pair of front and rear fold lines 4 are formed across the left and right at a position spaced apart by half the length of the object to be packed 40 in the front and rear direction from the center line l parallel to the edge, and these fold lines 4
A pair of front and rear fold lines 3 formed apart from the front or rear by a length corresponding to the total height of the object to be packed 40
and a fold line 5A formed diagonally from the left end point 31 of the rear fold line 4 to the front fold line 4 along the diagonal edge 45 of the object to be packed 40, and this fold line 5A. A fold line 6A is formed parallel to the left side of the fold line 5A and separated from the fold line 5A by a length corresponding to the total height of the object to be packed 40, and a point 32 where the fold line 5A hits the front fold line 4.

Fold lines 6A formed apart by a length corresponding to the total height of the component 40, and a cut 7A formed across from the point 32 where the fold line 5A hits the front fold line 4 to the front fold line 3. , a cut 8A formed from a point 33 where the fold line 6A hits the front fold line 4 to the front fold line 3, and these fold lines 5A, 6A and 7A, 8A are symmetrical about the center line l. Fold lines 5B and 6 formed as follows
B and cuts 7B and 8B. The packing sheet 1 also has a planar rectangular end cover 10 which is connected to the right edge of the packing sheet main body 2 via a fold line 9 formed between a pair of front and rear fold lines 4. The end cover 10 has a fold line 11 that is parallel to the fold line 9 and separated by a length corresponding to the total height of the top plate component 40, and the fold line 11 and the fold line 9 are connected to each other. A small rectangular front and rear ear piece 1 is attached to the front and rear edges of the end cover 10 between the fold lines 12
3 are installed in succession. Note that the item to be packed is not limited to the top plate component 40 of the sink, but may have a planar shape similar to the top plate component 40,
It suffices if it is plate-shaped, with one of its upper and lower surfaces being the surface to be protected.

(How to use the example) The usage of the embodiment will be explained below.

First, when the top plate component 40 is placed in an inverted state on the packaging sheet 1 as shown in the figure, a fold line 5A is formed along the diagonal edge 45 of the top plate component 40.
The main body 2 is shaped like a dashed line shown in FIG.
A cut 14A is formed extending from the outer edge of the cut line to the outer edge of the cuts 7A and 8A. Next, the top plate component 40 that has been turned over is
A and fold line 9, place it on main body 2, fold the left side of fold line 5A along fold line 5A so as to cover left wall 46 of top plate component 40, cut 7A, cut The part separated by 8A and the cut 14A is used as a corner cover 15, and the corner 48 at the left end of the front edge of the top plate component 40 is folded along the fold lines 3 and 4 of the corner cover 15. The part on the left side of the fold line 5A other than the part that covered the left wall 46 of the top plate component 40 is covered with the fold line 6A so as to cover the left end of the upward surface of the top plate component 40. Then, the right side of the fold line 9 is folded along the fold line 9 to cover the right wall 47 of the top plate component 40, and the front and rear tabs 13 are folded along the fold line 12 at the right end of the front wall 43 and back guard 4
4 to cover the right end of the rear wall of the top plate component 40, and fold the right side of the fold line 11 along the fold line 11 to cover the right end of the upward surface of the top wall 42 of the top plate component 40, and then , the remaining front part of the main body 2 is folded along the fold line 4 so as to cover the front wall 43 of the top plate component 40, and the portion of the top plate component 40 other than the part that covers the front wall 43 is folded along the fold line 3. , bend the top plate component 40 so as to cover the front end of the upward surface of the top wall 42, and fold the remaining rear portion of the main body 2 along the fold line 4.
Then, bend the back guard 44 of the top plate component 40 so as to cover the rear wall thereof, and fold the rear side of the fold line 3 along the fold line 3 to fold the top wall 4 of the top plate component 40.
Fold it to cover the rear end of the upward facing side of 2.
In this way, the top plate component 40 is
After covering, if necessary, a hat-shaped cover 16 having a triangular planar shape is fitted over the left end of the top plate component 40, and the whole is secured with duct tape, a band, or the like. In addition, if necessary, a cushioning material 17 is provided in the space between the top plate component 40 and the packaging sheet 1.
It is also possible to intervene.

In addition, when the diagonal edge 45 of the top plate component 40 placed upside down on the packaging sheet 1 is along the fold lines 5B and 6B, a cut is made from the outer edge of the main body 2 as shown in the dashed line in FIG. By forming the cuts 14B extending to the outer ends of 7B and 8B, the top plate component 40 can be packed in the same manner as described above.

(Effects of the invention) As described above, according to this invention, the packaging sheet main body 2 has the fold lines 5A, 6A, 7A, 8A, and the fold line 5B formed so as to be symmetrical with respect to the center line l. 6B and cuts 7B and 8B, and by the simple operation of forming a continuous cut in either of these cuts, when one of them is reversed, it becomes the same planar shape as the other. It is extremely economical because desired items to be packed can be packed.
