Description

The present invention relates to a opened confirmation carton.

By leaving traces on the box once opened, it is possible to manage the box (things in the box are in use or used, etc.), remove things in the box, prevent unauthorized opening of the box including falsification, etc. Those who try to discover are known.

Patent Document 1 discloses a packaging box (paperboard) in which a range to be torn by a fingertip is surrounded by a breaking line and a half-cut notch is formed in the vicinity of the breaking line on the outside of the breaking line. When the area surrounded by the break line is pushed through, half of the paperboard is peeled off between the break line and the half-cut notch, and the intermediate layer of the paperboard is exposed. It can be confirmed that it has been done. However, if the color of the intermediate layer of the paperboard is close to the color of the surface of the paperboard, the exposure of the intermediate layer is less noticeable. If the distance between the break line and the half-cut notch is widened to make the exposure of the mesosphere stand out, the resistance at the time of opening will increase.

In Patent Document 2, the outer lid piece is divided into a main body and a pair of corners at both ends by an auxiliary break line, and when the lid of the packaging box is opened, the corners at both ends are separated from the outer lid piece at the auxiliary break line. Describe what is to be separated. The corners of both ends automatically rise due to the bending repulsive force, which confirms that the package has been opened. However, the amount of rise is not stable because the rise of the corners at both ends depends on the bending repulsive force.

An object of the present invention is to provide a carton that can be easily confirmed to have been opened.

The opened confirmation carton according to the first invention includes a bottomed tubular body portion and a closing portion for closing the upper opening of the tubular body portion, and the closing portion is connected to the upper end edge of the back surface of the body portion. It is provided with a top surface portion that closes the upper opening of the body portion, and an insertion piece that is connected to the tip of the top surface portion and is inserted into the front surface of the body portion. A free surface portion that is adhered to the outer surface of the insertion piece and is pushed away from the body portion by being pushed in, and a free surface portion that is formed adjacent to the lower part of the free surface portion and is connected to the body portion at the lower side and is pushed in. As a result, the remaining piece that falls inward with the lower side as the axis is formed, and the insertion piece has a dimension extending to the front of the remaining piece that falls inward when the closed portion is reclosed. ing.

The free surface formed on the upper end of the front surface of the body of the opened confirmation carton is pushed off from the body by being pushed. Since the free surface portion is adhered to the outer surface of the insertion piece connected to the tip of the top surface portion, when the top surface portion (closed portion) is opened and the insertion piece is pulled out from the body portion, the free surface portion is together with this. Moving. At the upper end of the front face of the body where the free surface was formed, there is a hole (recess) of a size corresponding to the crushed free surface.

In one embodiment, the free surface portion has one end reaching the upper edge of the body portion, has a length shorter than the length of the insertion piece, and is a pair of first vertical portions formed on the body portion at intervals. The trunk sandwiched between the orientation break line, the first horizontal break line formed on the body portion connecting the other ends of the pair of first vertical break lines, and the pair of first vertical break lines. It is the range surrounded by the upper edge of the part. The free surface portion can be pushed through from the body portion along the pair of the first vertical break line and the first horizontal break line. The pair of first vertical break lines and the first horizontal break lines are made up of through-cut lines, perforations, half-cut lines, intermittently formed holes, etc., which are formed leaving a joint. ， The free surface part is kept flush with the body part until it is pushed in (keeps it as a part of the body part), and when it is pushed in, the free surface part can be easily pushed through the body part.

At the upper end of the front surface of the body, the remaining piece is formed adjacent to the lower side of the free surface and is connected to the body at the lower side, and when pushed, the remaining piece falls inward with the lower side as the axis. It is formed. Since the remaining piece is adjacent to the free surface portion, when the free surface portion is pushed in to break through the free surface portion, the remaining piece is also pushed in together. Since the remaining piece is connected to the body at the lower side, the pushed remaining piece falls inward with the lower side as the axis.

Preferably, the remaining piece has one end located at both ends of the first lateral breaking line defining the free surface portion and the first lateral breaking line, and when the length of the free surface portion is added up, the remaining piece of the insertion piece It has a length that is long, and is formed on the body that connects the other ends of the pair of second vertical break lines and the pair of second vertical break lines that are formed on the body at intervals. It is a range surrounded by the second horizontal ruled line. With the remaining piece connected to the body at the second horizontal ruled line (lower side), the remaining piece can be tilted inward.

According to the present invention, the insertion piece hidden behind the remaining piece when unopened is located in front of the remaining piece when reclosed. Inserts that were not visible when unopened can be made visible when reclosed.

For example, it has been opened (reclosed) by printing a specific character (such as "opened") on the outer surface (surface) of the insert piece, or coloring the insert piece in a color different from the carton. Can be shown in an easy-to-understand manner.

The opened confirmation carton according to the second invention includes a bottomed tubular body and a closing portion that closes the upper opening of the tubular body, and the closing portion is the upper end edge of the back surface of the tubular body. It is provided with a top surface portion that is continuously installed in the above to close the upper opening of the tubular body portion and an insertion piece that is continuously installed at the tip of the top surface portion and is inserted into the front of the tubular body portion. A free surface portion that is adhered to the outer surface of the insertion piece at the upper end of the front surface of the body portion and is pushed away from the body portion by being pushed in, and a free surface portion that is formed adjacent to the lower portion of the free surface portion and is pushed in. As a result, a window forming piece to be separated from the body is formed, and the insertion piece reaches the window formed by separating the window forming piece when the closing part is reclosed. have.

According to the second invention, the insertion piece hidden behind the window forming piece when unopened can be seen through the window formed by separating the window forming piece from the body when reclosed. Inserts that were not visible when unopened can be made visible when reclosed.

It is a blank of a rectangular parallelepiped carton. It is a perspective view of a rectangular parallelepiped carton. It is a perspective view of the rectangular parallelepiped carton after opening. It is a perspective view of the rectangular parallelepiped carton after reclosing. It is a perspective view of the rectangular parallelepiped carton after the reclose of another example.

1 to 5 show an example of a carton (folded box).

FIG. 1 shows a blank 1A (developed view) of a rectangular parallelepiped carton 1B (see FIG. 2). The blank 1A is formed by punching out a paperboard. Corrugated cardboard, plastic sheets, etc. can be used instead of paperboard.

With reference to FIG. 1, the carton blank 1A includes a right side panel 11, a rear side panel 12, a left side panel 13, a front panel 14, and a glue margin piece 15 which are continuously provided in a row in a horizontal direction. The top panel 22 is continuous at the upper end of the rear panel 12, and the insertion piece 24 is further continuous at the tip of the top panel 22. The outer bottom panel 32 is continuous at the lower end of the rear panel 12. The inner bottom panel 34 is continuous at the lower end of the front panel 14. In addition, flaps 21, 31, 23, and 33 are continuous on the upper and lower ends of the right side panel 11 and the left side panel 13, respectively.

These right side panel 11, rear side panel 12, left side panel 13, front panel 14, glue margin piece 15, top surface panel 22, insertion piece 24, outer bottom panel 32, inner bottom panel 34 and flaps 21, 23, 31 , 33 are separated by the fold line indicated by the alternate long and short dash line. In order to make it easier to fold in the carton assembly process, it is advisable to make creases along the fold lines in the blank punching process.

At the upper end of the front panel 14, a free surface portion 41 and a remaining piece 42 are formed continuously in the vertical direction.

At the upper end of the front panel 14, a pair of vertically extending break lines 41A formed at intervals on the left and right and a pair of notch lines 41B extending horizontally in the direction connecting the lower ends of the pair of break lines 41A are formed. There is. The upper end of the pair of break lines 41A reaches the upper edge of the front panel 14. The front panel 14 has the above-mentioned free surface portion formed by the pair of breaking lines 41A, the upper edge portion of the front panel 14 sandwiched between them, and the notch line 41B extending laterally in the direction connecting the lower ends of the pair of breaking lines 41A. 41 is specified.

The front panel 14 also has a pair of cut lines 42A having an end near the lower end of the pair of break lines 41A and extending vertically in a slightly outward arc shape with a space between the left and right sides, and a pair of cut lines 42A. A fold line 42B extending laterally in the direction connecting the lower ends is also formed. The pair of cut lines 42A, cut lines 41B, and fold lines 42B define the remaining piece 42 adjacent to the free surface portion 41 below the free surface portion 41 on the front panel 14.

The pair of break lines 41A defining both side edges of the free surface portion 41 are, for example, a plurality of short cuts formed discontinuously through short joints (perforation line of sight). The shape of the notch may be a short straight line, a small hole, or a small bend line. The cut line 41B defining the lower side (upper side of the remaining piece 42) of the free surface portion 41 is a cut line that linearly penetrates the front panel 14 leaving connecting portions at both ends, for example. It does not necessarily have to be a through-cut line, and may be a perforated line or a half-cut line up to about half the paper thickness. In any case, as will be described later, when the free surface portion 41 is pushed in, it is sufficient that the free surface portion 41 can be easily pushed through from the front panel 14.

A pair of notch lines 42A defining both side edges of the remaining piece 42 and a folding line 42B defining the lower side of the remaining piece 42 fold the remaining piece 42 at the folding line 42B when the free surface portion 41 is pierced. It suffices as long as it stays connected to 14 and tilts inward (tilts inward with the folding line 42B as the hinge axis). The cut line 42A may be a through cut line, a perforation line, or a half cut line. The folding line 42B may also be a through-cut line, or of course, a half-cut line or a perforation line, as long as connecting portions are provided on the left and right sides thereof. Of course, the fold line 42B may be a fold rule (press rule).

With reference to FIG. 2, the carton 1B is assembled using the blank 1A described above. That is, the right side panel 11, the rear panel 12, the left side panel 13, the front panel 14, and the glue margin piece 15 are bent at a right angle between their adjacent ones, and the glue margin piece 15 is adhered to the inner surface of the right side panel 11. By doing so, a cylinder with an open top and bottom is formed. After forming the cylinder, the flaps 31 and 33 are bent at right angles, the inner bottom panel 34 and the outer bottom panel 32 are bent at right angles in this order, the inner bottom panel 34 and the outer bottom panel 32 are adhered, and the bottom is closed. Put the contents into the cylinder from the upper side of the opening. Fold the flaps 21 and 23 at right angles, bend the top panel 22 and the insertion piece 24 at right angles, and insert the insertion piece 24 on the inside of the front panel 14. Carton 1B is completed by adhering the outer surface of the insertion piece 24 to the inner surface of the free surface portion 41 of the front panel 14. The order of assembling the carton 1B is not limited to the above, and may be appropriately determined according to the operation of the assembling machine or the like.

With reference to FIG. 3, FIG. 3 shows the carton 1B in the opened state. When the free surface portion 41 is pushed toward the carton 1B with a finger, the free surface portion 41 is pushed from the front panel 14 along the break line 41A and the cut line 41B. When the top panel 22 is pulled up and tilted backward (rotating the top panel 22 backward around the boundary between the top panel 22 and the rear panel 12), the insertion piece 24 continuous with the top panel 22 becomes the carton 1B. Is pulled out from. As described above, since the free surface portion 41 is adhered to the insertion piece 24, the free surface portion 41 also moves together with the insertion piece 24. The upper part of the carton 1B opens, from which the contents can be taken out.

When the free surface portion 41 is pushed toward the carton 1B with a finger, the remaining piece 42 adjacent to the lower side of the free surface portion 41 is also pushed toward the carton 1B. Unlike the free surface portion 41, the remaining piece 42 is connected to the front panel 14 at the lower side (folding line 42B), so the remaining piece 42 is not completely cut off from the carton 1B, and both side edges are cut off by the cut line 42A. Can only be done. That is, the remaining piece 42 only tilts toward the inside of the carton 1B (slightly rotates toward the inside of the carton 1B about the lower side (folding line 42B)). As the remaining piece 42 tilts toward the inside of the carton 1B, a window 51 is formed in the area of the front panel 14 closed by the remaining piece 42.

With reference to FIG. 4, FIG. 4 shows the carton 1B in the reclosed state. When the opened top panel 22 is returned to its original position and reclosed, the insertion piece 24 pulled out from the carton 1B at the time of opening is inserted again into the carton 1B, and the top panel 22 is pushed downward. As described above, since the remaining piece 42 is tilted inward toward the inside of the carton 1B, when the insertion piece 24 is inserted into the carton 1B, the insertion piece 24 overlaps the outside of the remaining piece 42 in the carton 1B. A part of the insertion piece 24 is exposed to the outside through the window 51. The outer surface of the tip of the insertion piece 24 can be visually confirmed through the window 51.

For example, if the word "opened" is printed on the tip of the insertion piece 24 (Fig. 1), the word "opened" (Fig. 2) that was hidden by the remaining piece 42 and was not visible before opening was printed. ， It will be visible through the window 51 (Fig. 4). It is clearly shown that Carton 1B has been opened. On the contrary, it can be seen that the carton 1B is unopened by not seeing "opened".

Instead of printing the characters "opened", for example, the tip portion of the insertion piece 24 may be colored in a color different from that of the carton 1B.

Returning to FIG. 3, in order to bring the insertion piece 24 to the position of the remaining piece 42 (window 51) when reclosed, the length (insertion length) A of the insertion piece 24 is set from the upper edge of the front panel 14. The length C up to the folding line 42B defining the lower side of the remaining piece 42 may be substantially equal (may be slightly shorter). As a matter of course, the length B of the free surface portion 41 is formed shorter than the length A of the insertion piece 24. It suffices if there is a relationship in which the length (insertion length) A of the insertion piece 24 is approximately the sum of the length B of the free surface portion 41 and the length of the remaining piece 42.

FIG. 5 shows the carton 1C of the modified example, and shows the carton 1C in the closed state. It differs from the carton 1B shown in FIG. 4 in that the remaining piece 42 is cut off from the front panel 14.

For example, when the free surface portion 41 is pushed toward the carton 1C with a finger, the remaining piece 42 is not connected to the front panel 14 at the fold line 42B, but is cut off from the front panel 14 along the fold line 42B. Remove or try to fall into carton 1C. Since it is not possible to undo the inclination of the remaining piece 42 tilted in the carton 1B and cover the remaining piece 42 on the outside of the insertion piece 24 again, it is possible to make it easier to find the unauthorized opening. When the remaining piece 42 is cut off at the time of opening, the fold line 42B is such that the remaining piece 42 is easily cut off along the fold line 42B when the free surface portion 41 is pushed in, such as a cut line or a half cut line. do it.

It goes without saying that the overall shape of the cartons 1B and 1C is not limited to the rectangular parallelepiped shape. The above mechanism can also be used for triangular cylinders, pentagonal cylinders, hexagonal cylinders, other square cylinder cartons, and cylindrical cartons.
