Description

  The present invention relates to a plastic article packing pack used for packaging small products such as operation switches.

  Small products such as the operation switches mentioned above are shipped to users in a packaged state packed in a plastic packing pack.

  This type of packing pack is generally made of a rigid or semi-rigid sheet molded product made of general-purpose plastics such as polyethylene and polypropylene, and the pack structure is integrated with a tray and a cover for containing the packaged items. There is known a double-folded packing pack that is connected to (see, for example, Patent Document 1).

  The products such as the operation switches are shipped upon receiving an order from the user, and the number of orders at that time varies depending on the user. Therefore, usually a plurality of packs, each of which is made up of a plurality of packs as a unit, are formed by integrally forming a sheet by connecting the packs to the left and right, and separating lines such as perforations and notches between the packs. After preparing a take-up pack, the multi-ply take-up pack is stocked and stored in a packed state, and the required number of packs are separated and shipped according to the number of orders from the user.

  Next, FIG. 3 and FIG. 4 show the conventional structure of a two-fold type packing pack adopted for packaging the operation switch. 3 (a) and 3 (b) are perspective views showing a state before and after assembly of one pack separated from a multi-pack sheet, and FIG. 4 shows five packs as an example. FIG. 3 is a development view of a multi-piece pack sheet in which individual packs are connected to the left and right as a set unit and integrally formed into a sheet.

  First, in FIGS. 3A and 3B, 1 is a tray-shaped saucer that accommodates products, 2 is a cover that overlaps the upper surface of the saucer 1 and covers it, and 3 is a boundary between the saucer 1 and the cover 2. A hinge part that can be folded along a crease line, and in the peripheral area of the saucer 1 and the cover 2 are flanges 1a and 2a that overlap each other in the assembled state of the pack, and the cover 2 in the assembled state of the pack. A T-shaped engaging claw 2b and an engaging groove 1b are formed.

  4 is a developed view of the multi-piece pack sheet 4. In FIG. 4, A is a crease line corresponding to the hinge portion 3 (see FIG. 3), and B is a contour of the pack formed by patterning on the multi-piece pack sheet. A separation line along the boundary is represented, and the separation line B is formed with a perforation, a notch, or a half-cut process to form a breaking line so that each pack can be separated later.

  In the packing pack having the above configuration, after the product (not shown) is accommodated in the tray 1 with the cover opened in FIG. 3A, the cover 2 is folded along the hinge portion 3 and folded on the tray 1; Subsequently, the engaging claw 2b of the cover 2 is inserted into the engaging groove 1b of the receiving tray 1 and hooked on the back side thereof, whereby the pack assembled state shown in FIG.

Further, in order to divide the pack from the multi-cavity pack sheet 4 in FIG. 4, the pack is separated by a break line (perforation or the like) formed along the separation line B.

  By the way, the multi-pack with the conventional structure described above has the following problems in terms of handling.

  That is, as shown in the developed view of FIG. 4, if the separation line B formed between the packs in accordance with the outline shape of the pack is a straight line, each pack is separated in the two-fold assembly state of FIG. If it divides | segments along B, the corner | angular part of the both ends turned up by the hinge part 3 will come out in edge shape (right angle). For this reason, when a user or the like handles the packing pack with his bare hands, his / her fingers may touch the folded corner and hit an edge protruding at a right angle, which may cause an unexpected injury (stab or cut). Improvement measures are required.

  For such a problem, the fold line A and the separation line B intersect in the forming process of the multi-sheet pack sheet 4 shown in FIG. It is conceivable to punch a diamond-shaped hole that has a concave arc on each side, and chamfering it, but this chamfering method requires a punching process separately from the sheet forming of the pack. Packing packs are expensive.

  The present invention has been made in view of the above points, and has an improved safety by improving the shape of the pack so that there is no risk of injury even if the pack is touched with bare hands without requiring the chamfering process described above. The purpose is to provide a packing pack.

In order to achieve the above object, according to the present invention, a pack for packing an article having a bi-fold structure made of a rigid or semi-rigid resin sheet molded product, wherein the tray and the cover for storing the article are crease lines. In which a hook part that overlaps with each other in the assembled state of the pack and a latching part are formed in the peripheral area of the tray and the cover through a foldable hinge part formed along
On the periphery of the folding part of the heel part corresponding to the hinge part, a corrugated contour shape in which a substantially semicircular peak and valley part are point-symmetrically connected with the intersection with the crease line of the hinge part as the center of symmetry. (Claim 1).

  Further, in the above-described configuration, the separation line of the multi-pack package sheet in which a plurality of packs are connected to the left and right according to the corrugated contour shape formed on the periphery of the collar portion with the intersection with the crease line as the center of symmetry. (Claim 2).

  According to the packing pack having the above configuration, in the assembled state of the pack folded back and overlaid on the tray, the above-described corrugated crest and trough overlap each other around the crease line, and both end angles of the hinge portion A smooth mountain portion having a substantially semicircular shape protrudes outward from the portion. Therefore, there is no risk of injury even if the peripheral edge of the packing pack is touched with bare hands, so that the packing pack can be handled safely.

  In addition, by forming separation lines of the multi-pack pack sheet in accordance with the corrugated contour shape, additional steps such as R-shaped chamfering and punching at the corners at both ends of the hinge portion as described above This avoids an increase in pack cost.

  Embodiments of the present invention will be described below based on the examples shown in FIGS. 1 (a) and 1 (b) are perspective views showing a state before and after assembly of one pack separated from a multi-pack sheet, and FIG. 2 shows five packs as an example. FIG. 5 is a development view of a multi-piece pack sheet obtained by integrally molding the packs in the left and right directions as a set unit, and an enlarged view of a main part thereof. The same reference numerals are given to portions corresponding to FIGS. 3 and 4. A description thereof will be omitted.

  That is, the packing pack of the illustrated embodiment is basically the same as the conventional structure shown in FIGS. 3 and 4, but the periphery of the flanges 1 a and 2 a formed in the peripheral area of the tray 1 and the cover 2 A substantially semicircular crest 5a and trough 5b are connected point-symmetrically with respect to the intersection with the crease line A of the hinge 3 that folds the pack in half to form a corrugated contour 5.

  Further, in the multi-pack package sheet 4 shown in FIG. 2, the separation line B between the packs is matched with the corrugated contour shape 5, and a break line such as a perforation is formed along the separation line B. Form it.

  2, in the assembled state in which the cover 2 is folded and overlapped on the tray 1, the corrugated peak 5a and valley 5b are connected to the hinge portion 3 in the assembled state. They overlap each other around the crease line. Thus, in the state where the individual packs are separated from the multi-piece pack sheet 4, as can be seen from FIG. 1 (b), a substantially semi-circular peak portion 5a is directed outward at the turning corner portion of the hinge portion 3. Will overhang.

  Therefore, when handling the packing pack for shipping products with bare hands, even if the finger touches the folded corner of the hinge portion 3, the edge shape is formed at the folded corner as in the conventional pack (see FIG. 3B). Can be handled safely without risk of injury.
