Description

  The present invention relates to a storage box in which a lid is closed with an adhesive such as a hot melt adhesive, and more particularly to a storage box capable of confirming the opening of the lid.

  A paper storage box for storing food, medicine, etc., comprising: a box body having an open upper surface; and a lid body that is connected to a first side plate of the box body and opens and closes an upper surface opening of the box body. An insertion portion that can be inserted into the box body along the inner surface of the second side plate facing the first side plate is formed at the free end portion of the body, and the second side plate and the insertion portion are hot-melt adhesive in the closed state Have been widely put into practical use with a closed lid structure in which a cut-out part that can be cut off by a perforation or a cut is formed on the second side plate so as to surround the adhesive part. .

  In this storage box, the finger can be pressed against the cutout part bonded to the lid with an adhesive such as hot melt adhesive, so that the cutout part can be separated from the box body along the perforations and cuts, and the lid can be opened. The cut-out part separated from the box body is configured to be kept attached to the insertion part.

  By the way, in the storage box, when the lid is returned to the closed state after opening, the cutout part is placed in the original position, and therefore, after the contents are removed or replaced, the lid is closed. There was a problem that it was not possible to easily find out that fraud was made by visual inspection.

  Therefore, as a storage box, it is possible to prevent the contents from being removed or replaced, and in the unlikely event that the contents are removed or replaced, it is easy to find out if the contents are opened. Various devices having functions have been proposed.

  For example, like a paper box described in Patent Document 1, a box body having a bottom plate and four side plates, and a lid body that is connected to the rear side plate and covers an opening of the box body, and a front end portion of the lid body Provided with an insertion part that can be inserted along the inner surface of the front plate, and a guide part having a longer insertion length than the other part of the insertion part is formed in the insertion part, and the lid corresponding to a position different from the guide part In the assembled state of the cover, the finger hook part that can form the hole part and the sealing means for connecting the finger hook part and the front side plate are formed, the finger hook part is cut off, and the hole part is formed in the cover body. There has been proposed a structure in which the unsealed display portion formed and printed on one side blade is visible through the hole.

JP 2005-298049 A

  In the paper box described in Patent Document 1, since the unsealed display portion printed on one side blade is configured to be visible through the hole portion, the position of the finger hook portion on the lid body is It is limited to the position facing the side blades in the state. However, ordinary paper boxes are closed by attaching a sealing tape to the center of the lid in the left-right direction so that various printings such as product names made on the lid are not hidden by the sealing tape. Because the various prints are laid out, as described in Patent Document 1, when the finger hook part is formed at a position facing the side wing plate, it is necessary to change the print layout for the cover body significantly. There is. In addition, because the side blades are supported by the contents, depending on the contents, the side blades may be tilted in the packaged state, and the opened display part is separated from the hole part. There is also a problem that it becomes difficult to see. Moreover, in the paper box described in Patent Document 1, it is indispensable to provide a sealing tape, and there is a problem that the manufacturing cost of the paper box becomes higher as compared with the case of bonding with a hot melt adhesive.

  An object of the present invention is to provide a storage box that can be implemented at low cost by using existing equipment and that can be easily and surely confirmed by visual inspection.

  A first openable storage box according to the present invention includes a box body having an open upper surface, and a lid body that is connected to a first side plate of the box body and opens and closes an upper surface opening of the box body, A folding part that is folded inward and overlapped with the second side plate is connected to the second side plate that faces the first side plate, and can be inserted into the free end of the lid body into the box body along the inner surface of the folding part. Forming a first cutout portion at a position facing the first cutout portion, and forming a second cutout portion at the folded portion at a position facing the first cutout portion. The second cutout part is bonded to the insertion part and closed.

  When opening the storage box that can be confirmed to be opened, the finger is pressed against the first cutout part, the first cutout part is separated from the second side plate, and the second cutout part is separated from the folded part, The lid is opened by opening the lid. At this time, since the second cutout part is adhered to the insertion part with an adhesive such as a hot melt adhesive, the second cutout part is attached to the insertion part, and the first cutout part is separated from the storage box and dropped off. become. For this reason, once the storage box is opened, since the first cutout part is dropped even if the lid is closed after that, the opening can be easily confirmed visually. In addition, the surface of the material sheet constituting the storage box is usually printed, but the back surface is plain or the background is left, and from the opening of the second side plate after the first cutout part is dropped Since the back surface of the second cutout portion is exposed, it can be clearly and easily confirmed that it has been opened based on the presence or absence of printing and the difference in printing form. Further, unlike the paper box described in Patent Document 1, since the sealing tape is not used, the degree of freedom of printing on the storage box is not restricted by the sealing tape.

  Here, in the storage box capable of confirming the first opening, a part of the second cut-out part is cut out to form an opening, and a display part for displaying the opened state is seen through the opening through the insertion part. It is a preferred embodiment that it can be formed. In this case, once opened, the opening of the second side plate formed by dropping off the first cutout part and the second cutout part were cut out even if the lid was returned to the original closed position. The display unit can be visually observed through the opening, and by printing characters such as “opened” on the display unit, anyone can easily confirm the presence / absence of opening. In addition, since printing is performed on the front surface side of the insertion portion, it is not necessary to perform printing on the back surface of the material sheet, and the printing process for the material sheet does not increase.

  It is also a preferred embodiment that the first cut-out portion is formed at the center in the left-right direction at the top of the second side plate. That is, the first cutout part can be formed at an arbitrary position in the left-right direction of the storage box, but the first cutout part is formed at the central part in the left-right direction at the upper part of the second side plate, as in the conventional storage box. Then, the 2nd cutting part formed facing the 1st cutting part can be adhere | attached with adhesives, such as a hot-melt-adhesive, to an insertion part using the existing equipment.

  A storage box capable of confirming the second opening according to the present invention includes a box body having an upper surface opened, and a lid body that is connected to a first side plate of the box body and opens and closes an upper surface opening of the box body, An insertion portion that can be inserted into the box body along the inner surface of the second side plate facing the first side plate is connected to the free end portion of the lid, and the upper portion of the second side plate is opposed to the insertion portion. One cut portion is formed, a second cut portion is formed on the second side plate adjacent to the first cut portion, and the second cut portion is adhered to the insertion portion and closed.

  When opening the storage box capable of confirming the second opening, the finger is pressed against the first cutout part, and the first cutout part is separated from the second side plate and opened. At this time, the second cutout part is opened. The part is pushed to the inside of the storage box together with the insertion part, and the second cutout part is cut off from the second side plate. For this reason, the second cutout part is attached to the insertion part, and the first cutout part is cut off from the storage box and falls off. Once the storage box is opened, the first cutout part is closed even after the lid is closed. Since one cut-out part has fallen off, it can be easily confirmed visually that it has been opened. In addition, since the surface of the insertion part is exposed through the opening after the first cutout part is dropped, printing of different forms such as colors and patterns on the outer surface of the storage box and the surface of the insertion part is possible. It can be clearly and easily confirmed that the package is opened due to the difference. Further, unlike the paper box described in Patent Document 1, since the sealing tape is not used, the degree of freedom of printing on the storage box is not restricted by the sealing tape.

  Here, in the storage box capable of confirming the second opening, a display portion for displaying the opening completion can be formed on the surface of the insertion portion facing the first cutout portion. In this case, by printing characters such as “opened” on the display unit, anyone can easily confirm the presence / absence of opening.

  It is also a preferred embodiment that the second cut-out portion is formed at the central portion in the left-right direction at the top of the second side plate. If comprised in this way, a 2nd cut part can be adhere | attached by a hot-melt-adhesive etc. to an insertion part using an existing installation, and a lid can be adhere | attached effectively using an existing installation.

  According to the first opening confirmation storage box according to the present invention, once the lid is opened, the second cutout portion is attached to the insertion portion, but the first cutout portion is separated from the second side plate. Therefore, even if the lid is closed after that, since the first cutout part has dropped off, it can be easily confirmed visually that it has been opened, and the contents can be prevented from being removed or replaced. Even if the contents are extracted or replaced, it can be easily found. In addition, the surface of the material sheet constituting the storage box is usually printed, but the back surface is plain or the background is left, and from the opening of the second side plate after the first cutout part is dropped Since the back surface of the second cut-out part is exposed, it can be clearly and easily confirmed whether or not it has been opened based on the presence or absence of printing or the difference in printing form. Moreover, since the 2nd cutting part is arrange | positioned in the front surface of a storage box, even when a storage box is stacked and installed, it can be confirmed whether it is opened from the front side. Further, unlike the paper box described in Patent Document 1, since the sealing tape is not used, the degree of freedom of printing on the storage box is not restricted by the sealing tape.

  According to the second opening confirmation storage box according to the present invention, as with the first opening confirmation storage box, it is easy to visually check whether or not the first cutting part has been opened or not. Even if the storage boxes are stacked and installed, it can be confirmed whether they are opened from the front side. Unlike the paper box described in Patent Document 1, no sealing tape is used, so printing on the storage box with the sealing tape is possible. The effect that the degree of freedom is not restricted is obtained. In addition, since the surface of the insertion part is exposed through the opening after the first cutout part is dropped, the printing form can be obtained by printing different forms such as colors and patterns on the outer surface of the storage box and the surface of the insertion part. It can be clearly and easily confirmed that the package is opened due to the difference. Furthermore, since it is not necessary to provide a folded portion, the storage box can be assembled by effectively utilizing the existing equipment as it is.

Can be glued to.

  In addition, when comprised like storage boxes 1A-1C, the formation position and shape of the 2nd opening part in a 2nd cutting part are the ranges which do not inhibit adhesion with the 2nd cutting part and insertion part 6 by adhesive 9 It can be set arbitrarily. Further, in the storage boxes 1D and 1E, the second cutout portions 8D and 8E are arranged in close contact with the first cutout portion 7, but a gap is formed near the first cutout portion 7 so that it is independent of the first cutout portion 7. And can be intermittently connected to the front side plate 3F outside the second cutout portion 8 through the perforation. Furthermore, the printing on the display units 25A to 25E can be made with characters and designs other than “opened” and “opened” as long as anyone can easily confirm that the package has been opened.
