Abstract

PURPOSE:To easily form and keep a gap between a body and a tongue part to easily insert an insertion piece without a possibility of intrusion of dust or the like and a need of removing punched chips at the time of machining by a method wherein an impression part is formed on the surface of the tongue part formed by a tongue-form notch. CONSTITUTION:An insertion piece 2 can be inserted into a tongue-form notch 4 formed in a body 3 to be fitted therein. An impression part 6 is formed in a tongue part 41 formed by the tongue-form notch 4 so that the tongue part 41 can get warped to one side of the body. When the tongue part 41 is directed to the insertion piece 2, the tongue part 41 is warped outward to be spaced a large gap from the body 3 for the easy insertion of the insertion piece 2. The impression part 6 can be formed by pressing a rule blade when a sheet blank to be made into the body 3 is formed. By pressing the impression part 6, the impression part 6 is depressed flat, the tongue part 41 is elongated, and the top of the tongue part 41 is caught by the tongue-form notch 4, whereby a gap can be kept.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case with a lid for closing an opening with a lid flap.

[0002]

2. Description of the Related Art In a case with a lid that has been generally used in the past, when the opening is closed, the insert piece at the tip of the lid flap is inserted into a tongue-like cut provided in the main body. Although there is a method of stopping with, there is no gap in the tongue-like notch, so there is a drawback that it is difficult to insert when inserting the insertion piece.

There is also a method in which a circular hole punched out in a circular shape is provided in place of this notch so as to make it easier to insert the insertion piece, but dust or the like is more likely to enter than a large circular hole, or a step for removing punching dust during processing is required. There are drawbacks such as high cost.

DISCLOSURE OF THE INVENTION The present invention has an improved notch for fitting an insertion piece. The insertion piece at the tip of the lid flap is fitted to the tongue-shaped notch of the case body to close the opening. In the case with lid described above, a pressing recess is formed on the surface of the tongue portion of the tongue-shaped cut, which will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an example of a case with a lid of the present invention, FIG. 2 is a partial sectional view taken along line II-II of FIG. 1, and FIGS.
FIG. 7 is a plan view showing another example of the pressing recesses on the surface of the tongue piece.

As shown in FIGS. 1 to 4, the present invention is a case with a lid in which the insertion piece 2 at the tip of the lid flap 1 is fitted into the tongue-shaped notch 4 of the case body 3 to close the opening 5. The case with lid is characterized in that a pressing recess 6 is formed on the surface of the tongue portion 41 of the tongue-shaped notch 4.

As the case body 3, a single sheet of amorphous polyethylene terephthalate, polyvinyl chloride, polypropylene or the like or a composite sheet is used to assemble a blank sheet formed by punching into a predetermined contour shape and forming folding ruled lines. For example, general case manufacturing technology can be adopted.

For example, as shown in FIG. 1, the lid flap 1 extends upward from the rear plate 31 of the case body 3 and can be folded forward to close the opening 5 in cooperation with the side flaps 32 and the like. I wish I could.

As shown in FIG. 1, the lid flap 1 is provided with an insertion piece 2 at a position corresponding to the tongue-shaped cut 4 of the main body 3. Although not shown, the insertion piece 2 may be laterally inserted so as to be inserted laterally into the tongue-shaped notch 4 that is also horizontally oriented, so that the fitted state can be made more reliable.

As shown in FIG. 2, the main body 3 is provided with a tongue-shaped notch 4 so that the insertion piece 2 can be inserted and fitted.

The tongue piece portion 41 of the tongue piece cutout 4 is formed with a pressing recess 6 so that the tongue piece portion 41 is bent back to one side of the main body. As shown in FIG. 2, when the tongue piece portion 41 faces the insertion piece 2, it bends outward and the gap 42 is easily opened between the tongue piece portion 41 and the main body 3, so that the insertion piece 2 is easily inserted.

Although not shown, when the tongue-shaped cut 4 and the tongue-shaped portion 41 are turned back inward when the tongue-shaped notch 4 and the tongue-shaped portion 41 face the opposite direction from the insertion piece 2, a large gap 42 is formed between the tongue-shaped notch 4 and the body 3. Easy to open, so insert piece 2 is easy to insert.

The pressing concave portion 6 can be provided by pressing with a ruled blade at the same time when a sheet blank for assembling the main body 3 is formed, and this pressing causes the pressing concave portion 6 to move in the direction of arrow 61 as shown in FIG. Since the tongue piece portion 41 is extended by pushing the tongue piece portion 41 and the tip of the tongue piece portion 41 is caught by the tongue piece notch 4, the gap is maintained, so that there is no fear that the insertion piece 2 becomes difficult to insert.

As for the shape and arrangement of the pressing concave portion 6, the pressing concave portion 6 is horizontally interrupted at the base of the tongue piece portion 41 as shown in FIG. 1, continuous or curved as shown in FIG. As shown, it can be appropriately set depending on the shape of the notch 4 or the insertion piece 2 such as an inverted T-shape, and by providing one or several pieces, the degree of extension and warp of the tongue piece portion 41 can be adjusted.

[0015]

According to the present invention, in the case with a lid in which the insertion piece at the tip of the lid flap is fitted into the tongue-like cut of the case body to close the opening, the surface of the tongue-like cut of the tongue-like cut is pressed. Since it is a case with a lid that features a recess, it is easy to open a gap between itself and the main body, and because the gap is maintained, it is easy to insert the insert piece and dust is entered because it is not a punching hole. There is an advantage that there is no fear or that there is no need to remove punching residue during processing.
