Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endless ink ribbon replenishment case for replenishing a cartridge with endless ink ribbons used in a printing device.

When replacing a used endless ink ribbon, it is uneconomical to replace a cartridge that can still be used, so a refill case containing the endless ink ribbon in advance is used so that only the used endless ink ribbon can be replaced. There is.

This case is made by assembling paper and other materials to reduce the cost, and when storing the previously stored endless ink ribbon in the cartridge, the bottom of the case is pressed to push out the endless ink ribbon. If the amount of movement of the endless ink ribbon at that time is large, the endless ink ribbon will fall down within the cartridge, requiring a troublesome work to stand it up.
To minimize the amount of movement of the endless ink ribbon, the case can be inserted into the cartridge and the endless ink ribbon can be pushed out. However, in the conventional case, when the bottom part is pressed, the wall part expands outward, so the size of the case must be reduced by that amount, which has the disadvantage that the capacity for storing the endless ink ribbon is reduced.

The present invention ameliorates this drawback. The bottom part is formed by four bottom pieces,
When the bottom portion is pressed from the outside, the bottom portion moves in the pressing direction without the wall portion expanding outward.
Therefore, even if the bottom part of the case is pressed when storing the previously stored endless ink ribbon in the cartridge, the wall part does not expand outward, and the endless ink ribbon becomes approximately the same size as the cartridge. Can accommodate more ribbon.

Embodiments of the invention are explained in the drawings.

The case is assembled from the paper shown in the exploded view in Figure 1. A first wall piece 1, a second wall piece 2, a third wall piece 3 having the same length as the first wall piece 1, and a fourth wall piece having the same length as the second wall piece 2, forming a wall portion. The wall pieces 4 have the same width and are successively connected in the longitudinal direction via folds 5, 6, and 7.

The first wall piece 1 is provided with a continuous piece 9 on the outside via a fold 8, and the second wall piece 2 and the fourth wall piece 4 are provided with a slit 10 and a slit perpendicular to the longitudinal direction, respectively. 11 are provided.

A first bottom piece 12, a second bottom piece 13, and a third bottom piece 1 having the same shape as the first bottom piece 12, forming a bottom part.
4, and a fourth bottom piece 1 having the same shape as the second bottom piece 13
5 are separated from each other to form fold 16 and fold 1, respectively.
7, the first side piece 1, the second wall piece 2, the third wall piece 3, and the fourth wall piece through the fold line 18 and the fold line 19.
They are sequentially connected to the wall pieces 4 of.

The first bottom piece 12 is provided with a triangular notch 20 and an extruded part 21 in contact with the notch 20, and the third bottom piece 14 is provided with a triangular notch 22 and an extruded part 23 in contact with the notch 22. It is provided.

On the first wall piece 1 and the third wall piece 3, respectively,
A small piece 24 and a small piece 25 are provided by U-shaped cuts in contact with the fold line 16 and the fold line 18.

To assemble the case, in Figure 1,
The wall piece 1, the second wall piece 2, the third wall piece 3, and the fourth wall piece 4 are respectively connected to the first bottom piece 12, the second wall piece
Fold the bottom piece 13, the third bottom piece 14, and the fourth bottom piece 15 at right angles to the paper back direction, and then fold the small piece 24
and small pieces 25 are made to protrude from the first bottom piece 12 and the third bottom piece 14, respectively.

The second wall piece 2 is bent at right angles to the third wall piece 3, and the second bottom piece 13 is placed on top of the third bottom piece 14 (FIG. 2).

The first wall piece 1 is bent at right angles to the second wall piece 2, the first bottom piece 12 is stacked on the extruded parts 23 of the second bottom piece 13 and the third bottom piece 14, and the first The extruded portion 21 of the bottom piece 12 is placed under the third bottom piece 14 (FIG. 3).

The fourth wall piece 4 is bent at right angles to the third wall piece 3, and each wall piece 1, 2, 3, 4 forms a wall section. The fourth bottom piece 15 is stacked under the third bottom piece 14 and the first bottom piece 12 is stacked, and each bottom piece 1
2, 13, 14, and 15 form the bottom part (4th
figure).

The continuous piece 9 is bent at right angles to the first wall piece 1 and is pasted over the fourth wall piece 4 to form the opening 2.
6, and the extruded parts 21 and 23 are arranged in parallel and exposed on the opening 26 side (Fig. 5,
Figure 6).

A folded endless ink ribbon (not shown) is stored in this case, a part of which is taken out through slits 10 and 11, and a cover (not shown) is attached to the case.

To replace a used endless ink ribbon in a cartridge (not shown), the endless ink ribbon is removed from the cartridge. Remove the cover and remove the small piece 24 and small piece 2 of the case.
5 with the thumb and middle finger of the left hand (both not shown). Each bottom piece 12, 13, 14, 15
Point your index finger (not shown) at the gathering point 26 (Fig. 5).
When each of the bottom pieces 12, 13, 14, 15 is moved downward by pressing with Store in the cartridge.

This invention can be assembled from materials such as paper at low cost.
This has the effect of increasing the storage capacity of endless ink ribbons.
