Description

  The present invention relates to a packaging container including a case and a tray accommodated in the case, and a tray included in the packaging container.

  As a container for storing confectionery or the like, a paper packaging container comprising a substantially square cylindrical case and a tray stored in the case is known.

  When the contents of such a packaging container decrease, the container itself may be larger than the contents, and the container may be an obstacle for the user. For this reason, a carton that can be used by being transformed into a small container by folding the tray in half is known (see, for example, Patent Document 1).

On the other hand, in the same packaging container, the side of the tray to be pulled out is placed in the pulling out direction so that the user can easily hold it when pulling out the tray from the case. A packaging container having a space that does not contain an object is known (see, for example, Patent Document 2).
JP 2002-308251 A JP 7-242230 A

  The carton described in Patent Document 1 is suitable for storing small contents such as granulated gum. However, when such a container is used for contents such as chocolate having a large size and mass, or used for a tray having a space that does not contain the contents, such as the container described in Cited Reference 2. In some cases, when the tray is folded in approximately half and transformed into a small container, there is an inconvenience that it is not possible to secure a capacity for storing the remaining contents, such as the area taken up as the height of the small container in the tray increases. It was. Further, in the same case, there is a problem that the deformed shape cannot be held firmly and opens.

  Accordingly, an object of the present invention is a packaging container comprising a case and a substantially rectangular parallelepiped tray that is accommodated in the case and opened on one side, and when the contents are reduced, the tray is deformed to be a small container. Another object of the present invention is to provide a packaging container that can hold a deformed shape.

  The packaging container of the present invention that solves the above problems is a packaging container that includes a case and a substantially rectangular parallelepiped tray that is accommodated in the case and that is open on one side, and the tray is a bottom surface that faces the opened side. An extension piece extending in the longitudinal direction from the center, a folding mechanism capable of being folded with the opening of the tray as an inner side in the vicinity of the central portion in the longitudinal direction of the bottom surface, and when the folding mechanism in the tray is folded on the bottom surface, It has the latching | locking part which can latch an extension piece, It is characterized by the above-mentioned.

  According to the present invention, when the contents of the tray are reduced, the contents can be stored by bending the folding mechanism into a small container that is about half the size of the tray. And it can prevent that the container after a deformation | transformation opens unexpectedly by latching an extension piece with a latching | locking part. Thus, according to the packaging container of the present invention, when the contents are reduced, the container can be deformed in a small size, and the deformed shape can be maintained.

  In the packaging container of the present invention, the case has a substantially rectangular tube shape with a pair of opposed surfaces opened, and the tray is housed so as to be able to be pulled out from the opening of the case. The extension piece has a severable notch that is connected in a direction intersecting in the longitudinal direction between the adhesion position of the extension piece and the side surface. The folding mechanism has at least two first folding lines having substantially the same width as the side surface in the width direction of the bottom surface, and the locking portion has the extension piece from the folding mechanism on the bottom surface. It is provided in the side which does not have.

  According to the present invention, when the contents of the tray are reduced, specifically, the cut portion of the extension piece of the tray is cut, and the first folding line is broken, so that it is about half the size of the tray. It can be transformed into a small container to store the contents. And the container after a deformation | transformation can be prevented from opening unexpectedly by latching the extension piece after cut | disconnecting a notch part by a latching | locking part. Thus, according to the packaging container of the present invention, when the contents are reduced, the container can be deformed in a small size, and the deformed shape can be maintained.

  In the packaging container of the present invention, the tray has a cross section in a direction in which the extension piece has at least four second folding lines in the width direction, and the four second folding lines are pulled out by being folded. It has the drawer part formed so that it may have a hollow part which is a rectangle.

  According to the present invention, in addition to the above-described effects, when the drawer portion is pushed from the opened side, the drawer is crushed in the direction of withdrawal, so that the user of the packaging container can easily draw out the tray. Moreover, since the site | part in which the notch part was provided becomes a drawer part and moves by pushing, it becomes easy for a user to cut | disconnect a notch part. Furthermore, even if the drawer portion is provided in the tray, it is possible to secure a volume when the tray is deformed in a small size.

  In the packaging container of the present invention described above, the width direction length of the tray on the side of the tray that does not have the extension piece from the bending mechanism, and the width of the bottom side of the tray that has the extension piece from the bending mechanism. The direction length is different.

  Therefore, when the folding mechanism is folded and transformed into a small container that is about half the size of the tray, for example, by increasing the width direction length on the side having no extension piece from the bending mechanism on the bottom surface The respective side surfaces on the side having the extension piece rather than the folding mechanism can be inserted into the respective side surfaces on the side not having the extension piece, and the deformed small container is difficult to lose its shape.

  The tray of the present invention that solves the above-mentioned problem is a tray that is open on one surface of a substantially rectangular parallelepiped shape, and is an extension piece extending in the longitudinal direction from the bottom surface facing the opened surface, near the longitudinal center of the bottom surface. A folding mechanism that can be bent with the opening of the tray inside, and a locking portion that can lock the extension piece when the folding mechanism in the tray is bent on the bottom surface. .

  Therefore, when the contents of the tray are reduced, the contents can be stored by being transformed into a small container which is about half the size of the tray by folding the folding mechanism of the tray. And it can prevent that the container after a deformation | transformation opens unexpectedly by latching an extension piece with a latching | locking part. Thus, according to the tray of the present invention, when the contents are reduced, the tray can be deformed in a small size, and the deformed shape can be maintained.

  According to the packaging container and the tray of the present invention, when the contents are reduced, the tray can be deformed in a small size, and the deformed shape can be maintained.

  Below, the packaging container and tray of this invention are demonstrated with reference to drawings. In addition, this embodiment is only one form for implementing this invention, and this invention is not limited by this embodiment.

It is the perspective view which shows an example of the tray provided in, and its sectional drawing. FIG. 4 is a view showing an example of a tray blank, and FIG. 5 is a view showing a process of deforming the tray. FIG. 6 is a perspective view showing another example of a tray and a diagram showing a blank body.

  As shown in FIG. 1 to FIG. 3, the packaging container 10 of the present invention includes a case 20 and a substantially rectangular parallelepiped tray 30 that is housed in the case 20 and opened on one side. In each figure, specifically, the case 20 has a substantially rectangular tube shape with a pair of opposed surfaces opened, and the tray 30 is housed so as to be drawable from the opening 21 of the case 20.

  The direction in which the tray 30 is pulled out is any direction (in the direction of arrow A in FIGS. 1 to 3) having the opening 21 in the case 20, and is usually the longitudinal direction in the packaging container 10. In the present invention, the direction A in which the tray is pulled out is referred to as the longitudinal direction, and the direction substantially perpendicular to the longitudinal direction on the bottom surface 31 of the tray 30 is referred to as the width direction.

  First, the tray 30 provided in the packaging container 10 is demonstrated using FIG. 3 thru | or FIG.

  As shown in FIG. 3 (a), the tray 30 has a bottom surface 31 and side surfaces 32, 33, 34, and 35 formed substantially perpendicular to the bottom surface 31 (rear side facing the front side surface 32 and the front side surface 32 on the drawer side). The side surface 33 is configured by a right side surface 34 on the right side from the opening side toward the front side surface 32, and a left side surface 35) facing the right side surface 34. The tray 30 has an extension piece 36 extending in the longitudinal direction from the bottom surface 31 facing the opened one surface, a folding mechanism 43 that can be folded around the central portion in the longitudinal direction of the bottom surface 31 with the opening of the tray 30 inside, The bottom surface 31 has a locking portion 47 that can lock the extension piece 36 when the bending mechanism 43 in the tray 30 is bent. Hereinafter, each configuration of the tray 30 will be specifically described.

  As shown in the blank body 40 in FIG. 4, the tray 30 has an extension piece 36 that extends in the longitudinal direction (the direction to be pulled out: the arrow direction in FIGS. 1 to 3) from the bottom surface 31 that faces the opened one surface. Yes. The extension piece 36 has a part 361 bonded to the bottom surface 31 to form the front side surface 32 on the side to be pulled out.

  The extension piece 36 has a cut portion 37 connected in the width direction between the adhesion position 361 and the side surface 32 of the extension piece 36. As shown in FIGS. 3 to 5, specifically, the cut portion 37 can be formed in a substantially V shape toward the distal end portion 362 of the extension piece 36. The cut portion 37 is a portion to be cut when the tray 30 is deformed as will be described later, and is cut in a perforated shape. In addition, the deformation | transformation form of the notch part 37 is later mentioned using FIG.

  3 and 4, the tray 30 has an extension piece 36 having at least four second folding lines 381, 382, 383, and 384 in the width direction so that a cross-sectional view is shown in FIG. The lead-out portion 42 is formed so as to be folded so as to have a hollow portion 41 having a rectangular cross section in the pull-out direction. In this shape, when the user grasps the drawer portion 42, a force is applied as shown by an arrow B in FIG. 3B, and the drawer portion 42 is easily crushed and held as shown by a broken line in FIG. 3B. The tray 30 can be easily pulled out from the case 20. In addition, the deformation | transformation aspect of the front side surface 32 is later mentioned using FIG.

  Further, as shown in FIGS. 3 and 4, the tray 30 has a folding mechanism 43 that can be folded with the opening of the tray 30 as the inside in the vicinity of the center portion of the bottom surface 31 in the longitudinal direction. The folding mechanism 43 has at least two first folding lines 431 that are substantially perpendicular to the longitudinal direction and have substantially the same or slightly larger width than the side surfaces 32, 33, 34, and 35.

  The bending mechanism 43 is configured to be easily deformed when the two first folding lines 431 are folded and the tray 30 is deformed. For example, as shown in FIGS. 3 and 4, the tray 30 is provided with two first folding lines 431 extending on the right side surface 34 and the left side surface 35, and two first folding lines 431 on the both side surfaces 34, 35. There are a notch portion 44 that is notched between the fold lines 431 in a substantially V shape, and a fold line 46 that extends from the tip 441 of the notch portion 44 to the intersection 451 between the two first fold lines 431 and the sides (folds) 45 of the tray 30. It has a shape. Therefore, since the portion for folding the tray 30 has the shape as described above, when the first fold line 431 is folded, the fold line 46 is naturally folded into the inside, and the user is transformed into a small container. It becomes easy. In addition, the deformation | transformation aspect of the bending mechanism 43 is later mentioned using FIG.

  The bottom surface 31 of the tray 30 is provided with a locking portion 47 that can lock the extension piece 36 when the folding mechanism 43 in the tray 30 is bent. Due to its function, the locking portion 47 is normally provided on the side C not having the extension piece 36 from the bending mechanism 43 on the bottom surface 31 of the tray 30 as shown in FIGS. The locking portions 47 shown in FIGS. 3 and 4 are two T-shaped straight lines that are cut substantially perpendicularly to a single straight line that is substantially parallel to the width direction of the bottom surface 31. The deformation | transformation aspect of the latching | locking part 47 is later mentioned using FIG.

  In the blank body 40 shown in FIG. 4, the side surfaces 32, 33, 34, and 35 are raised by folding the sides of the case 30 respectively, and the rear side surface 33 has rear pieces 48 extending from the right side surface 34 and the left side surface 35. The side surface 33 and the extension piece 331 are sandwiched and fixed by bonding or the like, and the front side surface 32 is folded so that the second fold lines 381, 382, 383 of the extension piece 36 are crested on the bottom surface 31 side, and the second fold line 384 is formed. The bottom surface 31 is folded so as to form a valley, and a part 361 on the tip side of the second folding line 384 is bonded to the inside of the bottom surface 31.

  Here, the process of transforming the tray 30 into a small container will be described with reference to FIGS. 3 and 5.

  By folding the two first folding lines 431 in FIG. 3 so that the bottom surface 31 is on the outside (see FIG. 5A), the other folding lines 46 are naturally folded and do not have the extension piece 36 in the tray 30. Side C looks like a lid. On the other hand, by cutting the notch portion 37 in FIG. 3 (see FIGS. 5A and 5B), the space of the drawer portion 42 becomes a space in which the contents can be stored as shown in FIG. 5A. . Further, as shown in FIG. 5C, the extension piece 36 after cutting the cut portion 37 bends the two second fold lines 381 and 382 close to the bottom surface 31, and the tip of the extension piece 36 is trayd. The small container 50 is inserted into the 30 locking portions 47.

  Subsequently, a modified embodiment of the tray 30 will be described with reference to FIG.

  As shown in the perspective view of FIG. 6 (a) and the blank body 40 of FIG. 6 (b), the front side surface 32 of the tray 30 is formed of three second folding lines 381, 382, 383. By having in the width direction, it has a shape having a normal edge. A portion 49 extending from the right side surface 34 and the left side surface 35 is sandwiched between the front side surface 32 and its extension piece 36, and a part of the extension piece 36 can be fixed by adhesion or the like. Also in this case, the extension piece 36 has a cut portion 37, and can be transformed into a small container 50 in the same manner as the tray 30 described above by being cut off from the tip of the cut portion 37.

  The cut portion 37 in the tray 30 is connected in the width direction between the adhesion position 361 and the side surface 32 of the extension piece 36, and is not particularly limited as long as it can be separated. For example, FIG. a), as shown in FIG. 6B, it may be formed in a straight line substantially parallel to the width direction of the extension piece 36, or may be formed in a substantially U-shape toward the tip 362 of the extension piece 36. Can do.

  Further, although not shown, the tray 30 does not have to have the cut portion 37. In that case, it is sufficient that a part 361 of the bonded extension piece 36 can be peeled off from the bottom surface 31, and the peeled extension piece 36 can be locked to the locking portion 47. Just do it. In this case, a part of the extension piece 36 is attached to the bottom surface 31 of the tray 30 with an adhesive or the like that can be attached and detached.

  On the other hand, the locking portion 47 in the tray 30 is not particularly limited as long as it can lock the extension piece 36 after cutting the notch portion 37. It may be a straight line, a curved line having another shape, or the like, and may be an elongated opening 471 as shown in FIGS. 6 (a) and 6 (b).

  The relationship between the extension piece 36 including the cut portion 37 and the locking portion 47 is not particularly limited as long as the locking portion 47 can be locked to the extension piece 36 as described above, but is not particularly limited. As shown in (c), the extension piece 36 may be inserted into the locking portion 47 without breaking the tip, or the extension piece 36 may be folded back and inserted into the locking portion 47 (not shown). Also good. Further, as shown in FIGS. 6A and 6B, a folding line 491 that is substantially parallel to the width direction in the middle of the extension piece 36 and a notch (engagement) that is convex on the front side 32 near the center. The engaging protrusion 492 may be inserted into the locking portion 471 by folding the folding line 491 from the protrusion 492.

  Moreover, the bending structure 43 cut | disconnects the position where the two 1st folding lines 431 in the right side surface 34 and the left side surface 35 of the tray 30 extended, as shown to Fig.6 (a) and FIG.6 (b), for example. A tear line 432 may be provided so that it can. Further, although not shown, the bent structure 43 has a configuration in which the cut line 432 in FIG. 6 is cut from the beginning, and the shape of the above-described notch portion 44 as shown in FIG. Can be configured to have a cutout portion 433 having a substantially rectangular shape in which the entire portion between the extended lines of the two first folding lines 431 on the right side surface 34 and the left side surface 35 is cut. Thus, the structure of the folding structure 43 is not particularly limited as long as it is provided in the vicinity of the central portion in the longitudinal direction of the tray 30 and can be bent with the opening of the tray inside.

  Here, regarding the fold 45 (side of the tray 30) 45 between the bottom surface 31 of the tray 30 and the right side surface 34 or the left side surface 35 in FIG. 3A, the extension piece 36 from the first folding line 431 on the bottom surface 31 of the tray 30. The width direction length W1 of the side C that does not have the width is different from the width direction length W2 of the side D having the extension piece 36 rather than the first folding line 431 at the bottom surface 31, and the first folding line 431 is broken. A straight line 45 can be used (a blank body is not shown). In this case, when the tray 30 is deformed into a different container 50 by making the width W1 and the width W2 slightly different, the width W2 of the tray 30 is increased (for example, the C side) while the width W2 is decreased. It becomes easy to cover the other (for example, D side). Of course, the crease (side) 45 described above may be a straight line.

  Each fold line 381, 382, 383, 384, 431, 45, 46, etc. in the tray 30 described above is formed with grooves, ruled lines, broken line cuts, half cuts, half cuts, etc. so as to be easily folded. Is preferred.

  Next, the case 20 provided in the packaging container 10 will be described.

  As shown in FIG. 2, the case 20 has a substantially rectangular tube shape and has a shape having openings 21 on two opposing surfaces, and is large enough to accommodate the tray 30 without excess or deficiency. Other configurations are not particularly limited, and a cutout portion 22 as shown in FIG. 2 may be provided on the side where the tray 30 is pulled out so that the user can easily take out the tray 30. The shape of the notch 22 may be a substantially trapezoidal shape as shown in FIG. 2 or may be a shape obtained by cutting a substantially square, a substantially triangular, a circle or an ellipse, and is not particularly limited. Although not shown, the case 20 may be provided with one or more windows so that the contents of the packaging container 10 can be seen. The notch 22 and the window are provided in consideration of design and the like.

In addition, condenser paper, paraffin paper, non-woven fabric, aluminum foil, or a film in which these are combined may be used. Note that the case 20 and the tray 30 are usually made of the same material, but may be made of different materials.

  In addition, the case 20 and the tray 30 are usually made from a single sheet-like material, but may be made from a plurality of materials. However, when a plurality of materials are used, it is preferable to use a single material because the number of steps for producing the packaging container 10 increases.

  The packaging container 10 is usually a rectangular parallelepiped shape, and has a shape that is long in the pulling-out direction of the tray 30 as shown in FIG. The ratio of each side of the rectangular parallelepiped is not particularly limited and is appropriately set according to the application.
