Description

  The present invention relates to a packaging box having a display function for displaying products while packaging them. More specifically, the packaging box of the present invention comprises a tray-like inner box part and an outer box part covering the periphery thereof, and packages products etc. in a state where these inner box part and outer box part are connected. It has the structure to do. For this reason, by releasing the connected state of the inner box part and the outer box part and removing the outer box part from the inner box part, it is possible to display the products in the packaging box as they are.

  Conventionally, it is a packaging box that can wrap a variety of products. When displaying products at a storefront, etc., the box that covers the tray-like part is separated from the tray-like part on which the product is placed. Therefore, what functions as a display shelf for goods is known. This type of packaging box is also called a shelf ready package. The shelf-ready package can be displayed as it is if the box is opened, so it has excellent workability at stores.

  As such a shelf-ready-package type packaging box, one disclosed in Patent Document 1 is known. The packaging box of Patent Document 1 is composed of an inner box part having a bottom surface and an outer box part covering the inner box part, and a product packaging operation or a work for separating a part of the packaging box and displaying the product.

  However, the packaging box of Patent Document 1 has a structure in which a part of the inner box part can be separated, and the inner box part and the outer box part are connected by applying an adhesive to the separation part. ing. As described above, the packaging box of Patent Document 1 requires an adhesive at the time of assembling, so that the assembling work becomes complicated, and it takes time for the assembling work to wait for the adhesive to dry. It was a thing.

  Moreover, the packaging box of Patent Document 1 forms a U-shaped notch in the outer box part, and includes a piece part formed by the substantially U-shaped notch and a separating part provided in the inner box part. We are going to bond. For this reason, by rotating to open one part of the outer box part, the separation part bonded to this one part is separated from the inner box part, and the connection between the outer box part and the inner box part is released. Can be done. However, in such a structure, for example, in the case where the adhesive state between one part of the outer box part and the separation part of the inner box part is insufficient, the outer part is separated before the separation part is separated from the inner box part. It is also assumed that the bond with the one part of the box part is peeled off. Then, there arises a problem that the outer box part cannot be separated from the inner box part well.

  As described above, in the conventional packaging box structure in which the outer box part and the inner box part are connected using an adhesive, the outer box part is separated from the inner box part when the packaging box is assembled. When opening, there was a problem that workability was bad. Therefore, there is a need for a shelf-ready-packaging packaging box that has excellent workability during assembly and opening.

Accordingly, the inventors of the present invention have intensively studied the conventional means for solving the problem, and as a result, the insertion flap is extended to the lower edge of the side surface of the outer box portion, and the insertion port is formed on the side wall of the inner box portion. A structure was proposed in which the outer box part and the inner box part were connected by inserting the insertion flap into the insertion slot. According to such a structure, after inserting the insertion flap of the outer box part into the insertion port of the inner box part and connecting them, the outer box part and the inner box part are assembled to easily form a packaging box. It becomes possible to do. Moreover, since the outer box part and the inner box part can be separated by simply pulling out the insertion flap from the insertion port, products etc. can be easily displayed using the packaging box. Then, the present inventors have conceived that the problems of the prior art can be solved based on the above knowledge, and have completed the present invention.
More specifically, the present invention has the following configuration.

The packaging box of the present invention includes an inner box part A and an outer box part B.
The inner box part A has a bottom surface 10 and side walls 20 standing around the bottom surface 10. The outer box portion B has a side surface 30 that covers the outer surface of the side wall 20 of the inner box portion A. The outer box portion B may have a top surface 40.
Here, the side wall 20 of the inner box portion A has at least one insertion port 26 at a position along the boundary line with the bottom surface 10.
On the other hand, the side surface 30 of the outer box part B has connection means 36 with the inner box part A. The connecting means 36 has an insertion flap 36 a that extends from the lower edge of the side surface 30 toward the bottom surface 10 and is inserted into the insertion port 26.
Accordingly, in the packaging box of the present invention, the inner box part A and the outer box part B are separated by extracting the insertion flap 36a from the insertion port 26.

  According to the above configuration, the outer box B and the inner box A can be connected by inserting the insertion flap 36a into the insertion port 26, so that the packaging box can be easily assembled. For example, with the inner box part A and the outer box part B in a flat state, the insertion flap 36a of the outer box part B is inserted into the insertion port 26 of the inner box part A, and both are connected. In condition, the packaging box manufacturer delivers the packaging box. Thereafter, a person who handles the packaging box can assemble the outer box portion B of the connected inner box portion A to form a packaging box, and can store articles therein. In this way, the packaging box can be transported (delivered) and assembled easily. Further, since the outer box part B can be separated from the inner box part A by pulling out the insertion flap 36a from the insertion port 26, products and the like can be easily displayed using the packaging box. Further, the packaging box of the present invention is provided with an insertion port 26 at a position along the boundary line with the bottom surface 10 in the side wall 20 of the inner box portion A, and is inserted into the lower edge of the side surface 30 of the outer box portion B. A flap 36a is provided. Thereby, since the substantially whole surface of the side wall 20 of the inner box part A can be covered by the side surface 30 of the outer box part B, the sealing performance in the packaging box is enhanced. Therefore, goods etc. can be safely stored in the packaging box.

  In the packaging box of the present invention, it is preferable that the connecting means 36 further has a movable piece 36b provided between two cutting lines or cutting guide lines formed on the side surface 30 and extending vertically. An insertion flap 36a is connected to the lower edge of the movable piece 36b through a broken line.

  As described above, by providing the movable piece 36b above the insertion flap 36a, the movable piece 36b rotates when the insertion flap 36a is inserted and removed. For this reason, the operation | work which inserts / extracts the insertion flap 36a in the insertion port 26 becomes easy.

  In the packaging box of the present invention, the connecting means 36 further includes a knob surrounded by a cut line or a cutting guide line formed on the movable piece 36b and a fold line provided between the insertion flap 36a. It may have a piece 36c.

  As in the above configuration, by forming the knob 36c connected to the insertion flap 36a in a part of the movable piece 36b, the separation flap 36a is separated from the inner case A when the outer case B is separated from the inner case A. It becomes easy to pull out from the insertion port 26. This further facilitates the work of unfolding the packaging box and displaying the merchandise.

  In the packaging box of the present invention, the movable piece 36b may be connected to the side surface 30 via a fold line formed at the upper end thereof.

  As described above, since the movable piece 36b is connected to the side surface 30 so as not to be separated, the insertion flap 36a can be repeatedly inserted into and removed from the insertion port 26. Therefore, even after the outer box portion B is once removed from the inner box portion A, the inner box portion A can be covered again by the outer box portion B and connected to each other. Thus, the packaging box of the present invention preferably has a resealable structure.

  In the packaging box of the present invention, the movable piece 36b is surrounded by a fold line provided between the insertion flap 36a and a cut line or a cutting guide line formed on the side surface 30. Also good. In this case, the movable piece 36b can be separated from the side surface 30 together with the insertion flap 36a.

  As described above, the packaging box of the present invention may have a structure in which the movable piece 36b and the insertion flap 36a can be completely separated from the side surface 30 of the outer box portion B.

Further, in the example shown in FIG. 1, a joining margin 35 is provided at the side end portion of the rear side plate 32. For this reason, the rear side plate 32 and the right side plate 34 can be connected by applying an adhesive to the bonding allowance 35 and bonding it to the right side plate 34.

In addition, a front top plate 41, a rear top plate 42, a left top plate 43, and a right top plate 44 are connected to the upper ends of the front, rear, left and right side plates 31 to 34 via folding lines, respectively. Each top plate 4
As the structure of the top surface 40 including 1 to 44, a known structure can be adopted as appropriate. In the example shown in FIG. 1, the top surface 40 has the same structure as a so-called A-type packaging box.

  Further, as shown in FIG. 1, a connecting means 36 is provided on the side surface 30 of the outer box portion B. The connecting means 36 is means for connecting the outer box part B to the inner box part A. The connecting means 36 basically has an insertion flap 36 a that can be inserted into the insertion port 26 formed in the inner box portion A. The insertion flap 36a is formed so as to extend from the lower edge of the side surface 30 toward the bottom surface 10 side (lower side). The same number of insertion flaps 36a as the insertion ports 26 are basically provided at positions corresponding to the insertion ports 26 formed in the inner box portion A. That is, in this embodiment, the insertion port 26 is formed in the front side wall board 21 and the rear side wall board 22 of the inner box part A one each. For this reason, the outer box B is provided with insertion flaps 36a (connection means 30) on the front side plate 31 and the rear side plate 32, respectively. And the outer box part B can be connected with the inner box part A by inserting the insertion flap 36a of the outer box part B into the insertion port 26 of the inner box part A.

  FIG. 2 shows an example in which the insertion flap 36a of the outer box part B is inserted into the insertion port 26 of the inner box part A and the outer box part B is connected to the inner box part A. At this time, in order to form the side wall 20 of the inner box part A, the rear side wall plate 22 and the right side wall plate 24 are joined via a joint allowance 25. Similarly, the rear side plate 32 and the right side plate 34 are joined via a joint allowance 35 in order to form the side surface 30 of the outer box portion B. Thus, the outer box part B and the inner box part B can be connected in the state folded flat. For this reason, for example, when a manufacturer delivers a packaging box, it is highly convenient because it can be transported and stored in a compact manner by delivering it in the state shown in FIG.

  After connecting the inner box part A and the outer box part B as shown in FIG. 2, the packaging box 100 is assembled. When assembling the packaging box 100, the bottom surface 10 needs to be assembled. FIG. 3 schematically shows a state when the bottom surface 10 is assembled. As described above, in the present embodiment, the bottom surface 10 has a double lid structure of an outer lid formed by the front outer plate 11 and the rear outer plate 12, and an inner lid formed by the left inner plate 13 and the right inner plate 14. It has become. That is, first, the left inner plate 13 and the right inner plate 14 are folded into the packaging box to form an inner lid, and then the front outer plate 11 and the rear outer plate 12 are folded into the packaging box to form an outer lid. By doing so, the bottom surface 10 of the double lid structure can be formed. In addition, the front outer plate 11 and the rear outer plate 12 forming the outer lid have engaging means 17 for engaging with each other. Here, an example of the engaging means 17 will be described.

  As shown in FIG. 3 and FIG. 1, the front outer surface plate 11 is formed with a pair of inner side protrusions 17 a on the left and right sides on the front end side, and the pair of inner side protrusions 17 a An outer central small protrusion 17b is formed therebetween. The outer center small protruding portion 17b has a shorter protruding length than the inner side protruding portion 17a. On the other hand, the rear outer plate 12 is formed with a pair of outer side protrusions 17c on the left and right sides on the front end side, and an inner central large protrusion 17d between the pair of outer side protrusions 17c. Is formed. The inner central large projecting portion 17d has a longer projecting length than the outer side projecting portion 17c. Here, in order to engage the front outer plate 11 and the rear outer plate 12, first, the inner central large protrusion 17 d of the rear outer plate 12 is submerged under the outer central small protrusion 17 b of the front outer plate 11. And insert it underneath. Thereby, the inner central large protrusion 17d overlaps with each other so that the outer central small protrusion 17b is positioned outside the box. At the same time, the inner side protruding portion 17a of the front outer surface plate 11 is inserted under the outer side protruding portion 17c of the rear outer surface plate 12 so as to be submerged. Thereby, it overlaps mutually so that the inner side protrusion part 17a is located inside a box, and the outer side protrusion part 17c is located outside a box. Thus, the three protrusions formed on the front outer plate 11 and the rear outer plate 12 are alternately stacked one above the other. In this way, the front outer plate 11 and the rear outer plate 12 are engaged with each other.

  Further, as shown in FIG. 1 and the like, the engaging means 17 for forming the bottom surface 10 of the inner box part A and the connecting means for connecting the outer box part B to the inner box part A are shown. 36 is formed on the same surface among the front, rear, left and right surfaces. That is, in the present embodiment, the engaging means 17 is formed on the front outer surface plate 11 and the rear outer surface plate 12 corresponding to the front surface and the rear surface of the inner box portion A. Similarly, the connecting means 36 is connected to the outer A front side plate 31 and a rear side plate 32 corresponding to the front and rear surfaces of the box B are formed. Thus, the packaging means 100 can be efficiently assembled because the engaging means 17 and the connecting means 36 are formed on the same surface among the front, rear, left and right surfaces. That is, as shown in FIG. 3, the operation of engaging the front outer plate 11 and the rear outer plate 12 provided with the engaging means 17 is performed, and at the same time, the connection provided on the front side plate 31 and the rear side plate 32. The means 36 (inserted flap 36a) bends at the fold line 38b. As described above, when the front outer plate 11 and the rear outer plate 12 are engaged, the connecting means 36 (inserted flap 36a) is inserted and fixed. Therefore, as shown in FIG. 2, even when the inner box part A and the outer box part B are connected in a flat state and then the packaging box 100 is assembled, the normal packaging box (inner box part and It can be assembled by the same operation as when assembling a packaging box that is not separated into the outer box. Therefore, even if the person who handles the packaging box assembles the packaging box 100 according to the present invention for the first time, it can be assembled relatively easily.

  FIG. 4 shows a state in which the packaging box 100 is assembled in a state where the insertion flap 36a of the outer box portion B is inserted into the insertion port 26 of the inner box portion A. As shown in FIG. 4, by assembling the packaging box 100 with the insertion flap 36a inserted into the insertion port 26, the outer case B is assembled so that almost the entire outer surface of the inner case A is covered. Go up. At this time, since the top surface 40 can be opened, goods and the like can be stored inside the packaging box 100 through the top surface 40 portion.

Here, the structure of the connecting means 36 will be described more specifically.
As shown in FIGS. 1 and 4, the connecting means 36 includes a movable piece 36b connected to the insertion flap 36a. The movable piece 36b is a portion that moves together with the insertion flap 36a when the insertion flap 36a is inserted into and removed from the insertion port 26. That is, as shown in FIGS. 1 and 4, the pair of cut lines 37 a are formed on the side surface 30. The two cut lines 37a extend in the vertical direction from the lower edge of the side surface 30. In addition, one fold line 38a extending in the left-right direction is formed so as to connect the upper ends of the two cut lines 37a. A single folding line 38b is also formed on the boundary line between the lower edge of the side surface 30 and the insertion flap 36a. In this case, the area surrounded by the two left and right cut lines 37a and the two upper and lower folding lines 38a and 38b is the movable piece 36b. The movable piece 36b is connected to the insertion flap 36a through a folding line 38b. Further, the movable piece 36b is partially separated from the side surface 30 by being provided with the two cut lines 37a, and can move freely. However, the movable piece 36b is not completely separated because it is connected to the side face 30 by a fold line 38a provided at the upper end thereof. Note that the two cut lines 37a extending vertically can be replaced with cutting guide lines (perforation lines).

  As shown in FIGS. 1 and 4, the connecting means 36 has a knob piece 36c formed in the movable piece 36b. The knob 36c is a portion that is held by the user when the insertion flap 36a is pulled out from the insertion port 26. For this reason, the knob | pick piece 36c is connected with the insertion flap 36a via the broken line 38b. That is, as shown in FIGS. 1 and 4, the movable piece 36b is formed with a cutting guide line 39a (perforation line) extending vertically. The movable piece 36b may be formed with a finger hooking hole 36d on the top of the knob 36c. In this case, the area surrounded by the cutting guide line 39a, the finger hooking hole 36d, and the folding line 38b is the knob 36c. The knob 36c can be separated from the movable piece 36b by breaking along the cutting guide line 39a. Even after the knob 36c is separated from the movable piece 36b, the movable piece 36b is connected to the insertion flap 36a via the folding line 38b. Therefore, the insertion flap 36a can be pulled out from the insertion port 26 by grasping and pulling the movable piece 36b. The cutting guide line 39a can be replaced with a cutting line.

  FIG. 5 shows an operation for releasing the connection state between the outer box part B and the inner box part A when the outer box part B is separated from the inner box part A. FIG. As shown in FIG. 5 (a), first, a finger is put into a finger hooking hole 36d formed on the top of the knob 36c, and the knob 36c is formed around the knob 36c. The cutting guide wire 39a is broken. Then, the knob 36c is laid sideways. Thereby, the pick piece 36c is separated from the movable piece 36b.

  Next, as shown in FIG. 5B, by pulling the knob piece 36 c, the insertion flap 36 a connected to the knob piece 36 c is pulled out from the insertion port 26. Thus, when pulling out the insertion flap 36a, the movable piece 36b connected to the insertion flap 36a rotates about the folding line 38a. Thereby, the insertion flap 36a can be easily pulled out from the insertion port 26. In this way, the connected state of the inner box part A and the outer box part B is released.

  FIG. 6 shows a state where the inner box part A and the outer box part B are separated from each other. As shown in FIG. 6, in the tray-shaped inner box portion A, the height of the front side wall plate 21 is lower than the height of the rear side wall plate 22. Further, the left side wall plate 23 and the right side wall plate 24 are cut obliquely so that the height on the front side is lowered. For this reason, by removing the outer box part B from the inner box part A, the products placed in the inner box part A can be visually recognized. Therefore, the packaging box 100 of the present invention can display the product as it is by installing the inner box part A on a display shelf or the like after removing the outer box part B. Thus, the packaging box 100 of the present invention has both a product packaging function and a product display function (exhibition function).

  As shown in FIGS. 6 and 1, the left bottom plate 13 and the right bottom plate 14 constituting the bottom surface 10 may be formed with notches 16 at the corners of the tip. Thus, by providing the notch 16 on the bottom surface 10, it is possible to prevent the insertion flap 36 a and the bottom surface 10 from coming into contact with each other when the insertion flap 36 a is inserted into the insertion port 26. For this reason, by forming the notch 16 in the bottom face 10, the insertion flap 36a can be smoothly inserted and removed.

  In addition, the packaging box 100 according to the first embodiment inserts the insertion flap 36a into the insertion port 26 even after the outer box portion B is removed from the inner box portion A as shown in FIG. Then, the outer box part B can be connected to the inner box part A again. For this reason, the packaging box 100 according to the first embodiment can reseal products.

Yes. In addition, a pair of cutting guide lines 39b that are inclined obliquely and extend in the vertical direction are formed above the cut line 37a. For this reason, the cut line 37a and the cutting guide line 38b are substantially connected. In addition, a single folding line 38c extending in the left-right direction (lateral direction) is formed in the movable piece 36b at a position serving as a boundary between the cut line 37a and the cutting guide line 39b. Therefore, the movable piece 36b is separated from the side surface 30 together with the insertion flap 36a by breaking the cutting guide wire 39b.

  7 and 8, a tongue piece 36e is provided above the movable piece 36b. The tongue piece 36e is an area surrounded by a substantially U-shaped cut formed in the side surface 30. Therefore, by pushing the tongue piece 36e into the box, a finger hooking hole 36d is formed at a position corresponding to the tongue piece 36e.

  FIG. 9 shows an operation for releasing the connection state between the outer box part B and the inner box part A when the outer box part B is separated from the inner box part A. As shown in FIG. 9A, first, the tongue piece 36e formed on the front side plate 31 is pushed into the outer box portion B. As shown in FIG. Thereby, a finger hooking hole 36d is formed at a position corresponding to the tongue piece 36e. The tongue piece 36e is formed at a position where it does not come into contact with the front side wall plate 21 of the inner box portion A when being pushed into the outer box portion B. That is, in the present invention, since the height of the front side wall plate 21 of the inner box portion A is low, the tongue piece 36e may be formed at a position higher than the front side wall plate 21. On the other hand, as shown in FIG. 7, the rear side wall plate 22 of the inner box portion A is formed with a relatively high height. For this reason, when the tongue piece 36e of the outer box part B is pushed in, it may come into contact with the rear side wall plate 22 of the inner box part A. In that case, as shown in FIG. 7, an opening 27 may be formed in the rear side wall plate 22 of the inner box portion A at a position corresponding to the tongue piece 36 e of the outer box portion B. The pressed tongue piece 36e is inserted into the opening 27. Thereby, the tongue piece 36e of the outer box part B can be prevented from being obstructed by the rear side wall plate 22 of the inner box part A.

  Thereafter, a finger is inserted through the finger hooking hole 36d, and the upper part of the movable piece 36b is gripped and pulled downward. At this time, the cutting guide wires 39b formed on both sides of the movable piece 36b are broken. As a result, the movable piece 36 b is completely separated from the front side plate 31.

  Further, as shown in FIG. 9B, an insertion flap 36a is connected to the lower end of the movable piece 36b. For this reason, the insertion flap 36a can be pulled out from the insertion port 26 by pulling the movable piece 36b completely separated from the front side plate 31. In this way, the connected state of the inner box part A and the outer box part B is released.

  FIG. 10 shows a state in which the inner box part A and the outer box part B are separated from each other. As shown in FIG. 10, in the tray-shaped inner box portion A, the height of the front side wall plate 21 is lower than the height of the rear side wall plate 22. Further, the left side wall plate 23 and the right side wall plate 24 are cut obliquely so that the height on the front side is lowered. For this reason, by removing the outer box part B from the inner box part A, the products placed in the inner box part A can be visually recognized. Therefore, the packaging box 100 of the present invention can display the product as it is by installing the inner box part A on a display shelf or the like after removing the outer box part B. Thus, the packaging box 100 of the present invention has both a product packaging function and a product display function (exhibition function).

  Further, in the packaging box 100 according to the second embodiment, after the outer box part B is removed from the inner box part A as shown in FIG. 10, the insertion flap 36a and the movable piece 36b are completely removed from the outer box part B. To separate. For this reason, the inner box part A and the outer box part B cannot be connected again using the insertion flap 36a (connecting means 36). According to such a configuration, it can be confirmed that the packaging box 100 has been opened once. That is, if the insertion flap 36a and the movable piece 36b are separated from the outer box portion B, it can be recognized that the packaging box 100 has already been opened.

  As mentioned above, in this specification, in order to express the content of this invention, embodiment of this invention was described, referring drawings. However, the present invention is not limited to the above-described embodiments, but includes modifications and improvements obvious to those skilled in the art based on the matters described in the present specification.

  The present invention relates to a packaging box with a display function formed by, for example, paper cardboard. Therefore, the present invention can be suitably used in the packaging box manufacturing industry, the paper manufacturing industry, and the like.
