When expanding the box-shaped container to one sheet material, all the pair of bonding members are provided on the one side surface of the sheet material, and one of the bonding members exposes the bonding surface to the other side surface of the sheet material through a through window provided on the sheet material.

Description

  The present invention relates to a packaging container with an opening / closing means that can be repeatedly opened and closed, and a sheet material with an opening / closing means for producing such a packaging container. The packaging container with an opening / closing means of the present invention is preferably used as a container for packaging processed foods and confectionery.

  Processed foods and confectionery, such as gums and chocolates, are wrapped in wrapping paper each time you eat at a time and stored in paper or plastic packaging containers (bags, boxes, etc.) May be. Consumers who purchase gum or chocolate sold in such a form do not eat all the gum or chocolate purchased at once, but usually one at a time and store the rest in the packaging container. . In this case, after opening the mouth of the packaging container and taking out one piece of gum or chocolate, it is preferable to keep the mouth of the packaging container closed again until the next meal.

  As a method of closing the mouth of the packaging container once opened, when the packaging container is a bag, there are a method of closing the mouth with a clip or a fastener provided in the mouth. Alternatively, when the packaging container is a box including a main body and a lid, there is a method of forming the main body and the lid into a pair of structures that engage with each other. However, if the mouth is sandwiched between clips, the impression of temporary fixing is very strong, and the clip becomes an obstacle, so there is a difficulty in handling when carrying. Further, when the main body and the lid are formed in a pair of structures that engage with each other, it may be difficult for an infant or an elderly person to open and close the mouth of the packaging container.

  In order to solve the above-mentioned problems, there is a method of providing a pair of hook-and-loop fasteners (Velcro) or a flaky magnet (a magnet layer or a magnet sheet) between the main body of the box-shaped packaging container and the lid. In such a structure, it is possible to close the mouth of the box-shaped container simply by pressing the surface fasteners and flaky magnets provided on the main body and the lid, respectively, and the attached surface fasteners and flaky magnets. Since they can be easily separated from each other, it is easy for an infant or elderly person to open and close their mouths, and it is easy to handle when carried in a pocket.

  However, many of the conventional box-shaped packaging containers for processed foods and confectionery are formed into a box shape in which a main body and a lid are integrated by bending a sheet material of a predetermined shape made of paperboard or plastic sheet. Is. FIG. 1A is a perspective view showing an example of such a packaging container 110, and FIG. 1B is a plan view showing a sheet material 120 for forming such a packaging container. The sheet material shown in FIG. 1 (b) has a shape in which the packaging container shown in FIG. 1 (a) is developed in a plane, and is folded along the fold shown in FIG. Then, it can be formed in a box shape having the main body 111 and the lid portion 112.

  More specifically, FIG. 1B is a view of the sheet material 120 as viewed from the side that becomes the inner surface of the box when formed in the box-shaped packaging container. The sheet material is a rectangular back member 121. Upper, lower, left and right side members connected to the four sides of the back member, a left front frame member 123 connected to the left side member 122, a right front frame member 125 connected to the right side member 124, and a lower side surface The front member 127 is connected to the member 126 and the front cover member 129 is connected to the upper side member 128. In addition, sticking pieces 126a and 126b for sticking to the left and right side members 122 and 124 are connected to the left side and the right side of the lower side member 126, respectively.

  The sheet material shown in FIG. 1 (b) has a pair of attachment members 130 and 131 made of a hook-and-loop fastener and a flaky magnet on the surface so that the mouth of the packaging container shown in FIG. 1 (a) can be opened and closed repeatedly. Have In the packaging container 110 of FIG. 1A, the pair of bonding members 130 and 131 are provided on a part of the outer surface of the main body 111 and the inner surface of the lid portion 112 that is bonded to the main body 111 from the outside. For this reason, as can be seen from FIG. 1B, the pair of bonding members 130 and 131 must be provided on the surface on one side and the surface on the other side of the sheet material, respectively. If a pair of bonding members are to be provided on both sides of the sheet material, after providing one bonding member on the surface of one side, the other bonding member must be provided on the other side surface again. In addition, since it is necessary to perform the process of forming the bonding member twice, there is a problem that the number of processes for manufacturing the packaging container increases.

  When forming a flaky magnet as a bonding member on the surface of a sheet material, a magnetic sheet having a magnetic material layer formed in advance on one side of a thin piece of paper or plastic is attached to a predetermined position on the surface of the sheet material. In addition to this method, a magnetic material layer can be applied to a predetermined region on the surface of the sheet material and then magnetized. However, in any case, the flaky magnet is used. It is still necessary to perform the forming process twice.

  The present invention relates to a packaging container having a content take-out port, and a box that can be developed into a single sheet material by integrating a main body in which the take-out port is formed and a lid portion that closes the take-out port. In the state where the take-out port is closed by the lid portion, one joining member that exposes the joining surface on the inner surface of the lid portion is the other that exposes the joining surface on the outer surface of the main body. When the box-shaped container is developed on a single sheet material, the take-out port can be repeatedly opened and closed by separating the pair of bonding members. Each of the pair of bonding members is provided on the surface of one side of the sheet material, and one of the bonding members is aligned with the surface of the other side of the sheet material through the extraction window provided in the sheet material. Solving the above problem by providing a packaging container characterized by exposing the wearing surface

  As a pair of bonding members, in addition to a pair of flaky magnets and hook-and-loop fasteners, a combination of flaky magnets and flaky iron sheets, or a material using an adhesive sheet that can be repeatedly separated, etc. should be used. Can do. Use of a pair of flaky magnets or hook-and-loop fasteners is preferable in terms of ease of handling.

  The other joining member to be joined with one joining member peeking from the extraction window is sized to fit in the extraction window or with some margin, and is provided at a position corresponding to the extraction window. Preferably it is. Thereby, when one joining member and the other joining member viewed through the extraction window are joined, there is no gap between the lid and the main body, so that the packaging container can be closed compactly. Furthermore, since there is no gap between the lid portion and the main body, it is easy to apply an overlap with a resin-made transparent film from above the packaging container.

It is a perspective view (a) which shows an example of the conventional box-shaped packaging container with a joining member, and a top view (b) which shows the sheet material with a joining member for forming it. It is a perspective view (a) which shows the box-shaped packaging container with a fusion member which concerns on one Embodiment of this invention, and a top view (b) which shows the sheet | seat material with a fusion member for forming it. It is a series of perspective views showing a part of a process of manufacturing a box-shaped packaging container with a binding member according to another embodiment of the present invention.

Fig.2 (a) is a perspective view which shows an example of the box-shaped packaging container with a pair of joining member (flaky magnet) based on one Embodiment of this invention, FIG.2 (b) is such packaging. The sheet material with a flaky magnet for forming a container is shown. The sheet material 20 shown in FIG. 2 (b) has a shape in which the packaging container 10 shown in FIG. 2 (a) is developed in a plane. The sheet material 20 is bent along the crease shown in FIG. If attached, it can be formed in a box shape having the main body 11 and the lid 12.

  More specifically, FIG. 2B is a view of the sheet material 20 as viewed from the side that is the inner surface of the box when formed in a box-shaped packaging container. The sheet material is a rectangular back member 21. Upper, lower, left and right side members respectively connected to the four sides of the back member, a left front frame member 23 connected to the left side member 22, a right front frame member 25 connected to the right side member 24, and a lower side surface A front member 27 connected to the member 26 and a front cover member 29 connected to the upper side member 28 are formed. In addition, sticking pieces 26a and 26b for sticking to the left and right side members 22 and 24 are connected to the left side and the right side of the lower side member 26, respectively.

  The sheet material shown in FIG. 2 (b) has a pair of flaky magnets 30 and 31 on its surface so that the mouth of the packaging container shown in FIG. 2 (a) can be repeatedly opened and closed. In the packaging container 10 of FIG. 2A, the flaky magnet 30 provided on the inner surface of the main body 11 is exposed to the outer surface of the main body through the extraction window 32 provided in the sheet material, and the lid portion 12 is provided there. The flaky magnet 31 provided on the inner surface of the magnet is attached. At this time, the vertical and horizontal lengths of the flaky magnet 31 provided on the inner surface of the lid portion 12 are slightly shorter than the vertical and horizontal lengths of the extraction window 32 provided in the main body 11, respectively. Just fits in the extraction window 32 and there is no extra space between the lid 12 and the body 11.

  As can be seen from FIG. 2B, the pair of flaky magnets 30 and 31 are both provided on the inner surface of the sheet material 20, that is, the surface on one side. However, although the flaky magnet 31 provided on the inner surface of the front cover member 29 is exposed as it is with the magnet surface facing the inner surface of the packaging container, the flaky magnet 30 provided on the inner surface of the front member 27 is The magnet surface faces the outer surface of the packaging container, that is, the sheet material side, and is exposed to the outer surface through the extraction window 32 provided in the sheet material.

  In order to form the flaky magnet 31, a magnetic material layer is applied and formed in a predetermined region on the surface of the sheet material, and then magnetized, so that the magnetic material is preliminarily formed on one side of a thin piece of paper or plastic. You may use the method of sticking the magnet sheet in which the layer was formed in the predetermined position of the sheet | seat material surface. However, in order to form the flaky magnet 30, the former method cannot be used because the forming region includes a window, and the latter method, that is, the magnet sheet is attached to a predetermined position on the surface of the sheet material. You must use the method of doing. Since using a different method to form the pair of flaky magnets increases the number of steps, in this embodiment, it is preferable to use a method of sticking the magnet sheet to the surface of the sheet material.

  In addition, in this embodiment shown to Fig.2 (a)-(b), although the joining member (flaky magnet) by the side of a main body has taken the structure exposed to an outer surface side through a extraction window, it is not the main body side. The cover side joining member may be configured to be exposed to the inner surface side through the extraction window. In any case, the pair of bonding members are provided on one side of the sheet material.
