Abstract

<P>PROBLEM TO BE SOLVED: To provide a paper sheet-made container which is manufactured at low cost and has a lid capable of being easily opened. <P>SOLUTION: A portion forming a body 1 and lids 2 extending from both sides thereof are formed in a blank formed of a paper sheet. The portion of the body 1 is pressed and formed in a tray shape, and the lids 2 on both sides are closed to cover an opening surface of the body 1. An insertion plate 5 is provided on a tip part of each lid 2, and these insertion plates 5 are butted to each other and inserted inside the body 1. Since the insertion plates 5 abut on each other, the closed condition of the lids 2 can be maintained, the inner side of the body is partitioned by the insertion plates 5, and the ends of the insertion plates 5 are extended to reach a bottom wall 6 of the body 1 for ensuring the compressive strength. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a lidded container formed from a paper sheet such as cardboard.

  Conventionally, as shown in FIG. 6, as a container for food or the like, a paper sheet such as cardboard is pressed to form a tray-like main body 51, and this main body 51 is covered with a plastic lid 52, and each other's flange is covered. A device in which 53 and 54 are engaged and closed is known.

  However, as described above, when the lid is manufactured separately from the main body, there is a problem in that it is costly and that it takes time to engage and disengage the main body and the flange of the lid when closing and opening the lid.

  Accordingly, an object of the present invention is to provide a paper sheet-made container that can be manufactured at low cost and that can be easily opened and closed.

  In order to solve the above-mentioned problems, the present invention provides a container in which a blank made of a paper sheet is formed by pressing. The blank is provided with a portion to be a main body and lids extending from both sides, and the main body portion is pressed to form a tray. The lids on both sides were closed to cover the opening surface of the main body.

  In addition, an insertion plate is provided at the tip of each lid, these insertion plates are butted into the main body, and further, the front end of the insertion plate is extended until it reaches the bottom wall of the main body. .

  In the paper sheet forming container as described above, since the lid is formed from the same blank as the press-molded main body, it is not necessary to separately manufacture the lid, the manufacturing cost can be suppressed, and the lids on both sides are in the form of double doors. It can be easily opened and closed.

  Moreover, when the insertion plate provided at the tip of each lid is abutted and inserted into the main body, the closed state of the lid is maintained by the contact of the insertion plates, and the inside of the main body is partitioned by the insertion plate. .

  Furthermore, if the insertion plate is extended until it reaches the bottom wall of the main body, the compressive strength can be increased, and the cover can be prevented from being depressed during stacking.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  This container accommodates a cone of soft cream and is formed from a cardboard blank shown in FIG. The blank is provided with a portion to be the main body 1 and a lid 2 extending from both sides thereof. A ruled line 3 is radially inserted into the corner of the main body 1, and an insertion plate 5 is connected to the end of the lid 2 via the ruled line 4.

  When manufacturing a container from such a blank, the blank is set in a mold, and the portion of the main body 1 is pressed so that the ruled line 3 forms a crease, as shown in FIG. 7 and a flange 8 are formed into a tray shape.

  Then, when delivering the soft ice cream cone to the store using this container, as shown in FIG. 3, a large number of cones are stacked and laid down and stored in the main body 1 in two rows.

  Next, the lids 2 on both sides are closed while the insertion plates 5 are bent inward along the ruled lines 4, and these insertion plates 5 are brought into contact with each other as shown in FIGS. Insert and cover the opening of the body 1. At this time, the insertion plate 5 reaches the bottom wall 6, and the lid 2 is placed on the flange 8.

  In the corrugated container as described above, the lid 2 is formed from the same blank as the press-molded main body 1, so that it is not necessary to manufacture the lid 2 separately, the manufacturing cost can be suppressed, and the lids 2 on both sides can be suppressed. Becomes a double spread and can be easily opened and closed.

  Moreover, since the insertion plate 5 of each lid 2 is abutted and inserted into the main body 1, the closed state of the lid 2 is maintained by the contact of the insertion plates 5 and the inside of the main body 1 is inserted. Divided by the plate 5, the movement of each row of cones is prevented.

  Further, since the lid 2 is supported by the flange 8 of the main body 1 and the insertion plate 5 reaches the bottom wall 6, the compression strength is excellent, and the lid 2 is prevented from being depressed during stacking.

  In the above embodiment, a paper sheet molded container used for packaging soft ice cream cones is shown. However, in other containers having different shapes, a press-formed main body and a similar lid provided with lids connected to both sides thereof are also provided. A configuration can be employed.
