[Embodiment 1]
A packing tool 300 according to the first embodiment of the present invention will be described with reference to FIGS. 1, 2A and 2B. FIG. 1 is a schematic perspective view of a packaging device 300 according to the first embodiment of the present invention. FIG. 2A is a schematic perspective view of the inner member 200. FIG. 2B is a schematic perspective view of the outer member 100.

In the following description, the X-axis direction of the coordinates shown in FIG. 1 is the left-right direction (the direction that is positive on the X-axis when viewed from the origin is the right direction), and the Y-axis direction is the front-back direction (the Y-axis is positive when viewed from the origin). There are cases in which the direction that becomes positive is the backward direction, and the direction of the Z axis (direction perpendicular to the XY plane) is the vertical direction (the direction that is positive on the Z axis when viewed from the origin is the upward direction).

As shown in FIG. 1, the packing 300 includes an outer member 100 and an inner member 200. The packing 300 is used by combining the outer member 100 and the inner member 200. The packing tool 300 can pack an object to be packed.

As shown in FIG. 2A, the inner member 200 has a bottom surface 210, a side surface 220a, and a side surface 220b. The side surface 220a is connected to the bottom surface 210. The side surface 220b is connected to the bottom surface 210. The side surface 220a is bent toward the +Z direction side with respect to the bottom surface 210. The side surface 220b is bent toward the +Z direction side with respect to the bottom surface 210. The side surface 220a is provided with a recess 222a. A recess 222b is provided on the side surface 220b.

In this specification, the side surface 220a and the side surface 220b may be collectively referred to as the side surface 220. Further, the recess 222a and the recess 222b may be collectively referred to as the recess 222.

As shown in FIG. 2B, the outer member 100 includes a bottom surface 110, a side surface 120a, a side surface 120b, an upper surface 130a, an upper surface 130b, a protrusion 140a, a protrusion 140b, and a protrusion 140c. And a protrusion 140d. Note that FIG. 2B shows a state in which the upper surface 130a, the upper surface 130b, the protruding portion 140a, the protruding portion 140b, the protruding portion 140c, and the protruding portion 140d are not bent.

The side surface 120a is connected to the bottom surface 110. The side surface 120b is connected to the bottom surface 110. The side surface 120a is bent toward the +Z direction side with respect to the bottom surface 110. The side surface 120b is bent toward the +Z direction side with respect to the bottom surface 110. In this specification, the side surface 120a and the side surface 120b may be collectively referred to as the side surface 120.

The upper surface 130a is connected to the side surface 120a. The upper surface 130b is connected to the side surface 120b. As shown in FIG. 1, the upper surface 130a is bent toward the +X direction side with respect to the side surface 120a. The upper surface 130b is bent toward the −X direction side with respect to the side surface 120b. In this specification, the upper surface 130a and the upper surface 130b may be collectively referred to as the upper surface 130.

Each of the protrusion 140a, the protrusion 140b, the protrusion 140c, and the protrusion 140d has a main body 142 and a recess 144. In this specification, the protrusion 140a, the protrusion 140b, the protrusion 140c, and the protrusion 140d may be collectively referred to as the protrusion 140. The height of the main body portion 142 (length along the Z-axis direction) is equal to the height of the side surface 220 (length along the Z-axis direction). Therefore, the tip of the protrusion 140 contacts the bottom surface 110 (see FIG. 1 ).

The protrusion 140 is connected to the upper surface 130. Specifically, the protrusion 140a is connected to the end of the upper surface 130a on the −Y direction side. The protrusion 140b is connected to the end of the upper surface 130a on the +Y direction side. The protrusion 140c is connected to the end of the upper surface 130b on the −Y direction side. The protrusion 140d is connected to the end of the upper surface 130b on the +Y direction side.

As shown in FIG. 1, the protrusion 140a is bent toward the −Z direction side with respect to the upper surface 130a. Similarly, the protrusion 140b is bent toward the −Z direction side with respect to the upper surface 130a. Further, the protrusion 140c is bent toward the −Z direction side with respect to the upper surface 130b. Similarly, the protrusion 140d is bent toward the −Z direction side with respect to the upper surface 130b.

The recess 144 corresponds to an example of “first recess”. The recesses 222a and 222b correspond to an example of “second recess”. The side surface 120a and the side surface 120b correspond to an example of “first side surface”. The side surface 220a and the side surface 220b correspond to an example of "second side surface".

The packing 300 has a configuration in which the outer member 100 and the inner member 200 are combined. The inner member 200 is placed on the bottom surface 110 of the outer member 100. The inner member 200 is located inside the outer member 100. The side surface 120a of the outer member 100, the side surface 120b of the outer member 100, the side surface 220a of the inner member 200, and the side surface 220b of the inner member 200 form the side surface of the packing device 300. Specifically, the side surface 120a of the outer member 100 and the side surface 120b of the outer member 100 form a side surface along the Y-axis direction of the packing device 300. The side surface 220a of the inner member 200 and the side surface 220b of the inner member 200 form a side surface along the X-axis direction of the packing device 300. The first side surface and the second side surface are orthogonal to each other. Specifically, the side surface 120a and the side surface 120b are orthogonal to the side surface 220a and the side surface 220b.

In the state where the outer member 100 and the inner member 200 are combined, the first recess and the second recess engage with each other. Specifically, the recess 144 of the protrusion 140a and the recess 222a are engaged with each other. Further, the recess 144 of the protrusion 140c and the recess 222a are engaged with each other. Further, the recess 144 of the protrusion 140b and the recess 222b are engaged with each other. Further, the recess 144 of the protrusion 140d and the recess 222b are engaged with each other. Therefore, the upper surface 130a and the upper surface 130b are fixed to the side surface 220a and the side surface 220b. As a result, the packing device 300 can be easily assembled without using an adhesive tape.

The outer member 100 will be further described with reference to FIGS. 1, 2A, 2B, 3A, and 3B. FIG. 3A is a development view of the outer member 100. FIG. 3B is an enlarged view of the vicinity of the protrusion 140a.

As shown in FIG. 3A, the bottom surface 110, the side surface 120a, the side surface 120b, the upper surface 130a, and the upper surface 130b are rectangular. A fold line 191, a fold line 192, and a fold line 193 are formed on the outer member 100. The folding line 191, the folding line 192, and the folding line 193 extend along the Y-axis direction. The side surface 120a and the side surface 120b can be bent with respect to the bottom surface 110 via a folding curve 191. The upper surface 130a can be bent with respect to the side surface 120a through a bending line 192. The upper surface 130b can be bent with respect to the side surface 120b via a bending line 192. The protrusion 140a and the protrusion 140b can be bent with respect to the upper surface 130a through a folding line 193. The protrusion 140c and the protrusion 140d can be bent with respect to the upper surface 130b through a folding curve 193.

As shown in FIG. 3B, the protrusion 140 a further includes a notch 146 in addition to the main body 142 and the recess 144. The notch 146 extends from the recess 144 along the X-axis direction. The recess 144 and the recess 222a (see FIG. 2A) are engaged so that the recess 222a (see FIG. 2A) reaches the notch 146. Therefore, it is possible to prevent the recess 144 from coming off from the state where the recess 144 and the recess 222 are engaged with each other.

The inner member 200 will be further described with reference to FIGS. 1, 2A, 2B, and 4. FIG. 4 is a development view of the inner member 200.

As shown in FIG. 4, the bottom surface 210 has a rectangular shape. The side surface 220a and the side surface 220b have a substantially rectangular shape. A fold line 291 is formed on the inner member 200. The folding curve 291 extends along the X-axis direction. The side surface 220a is bendable with respect to the bottom surface 210 via a folding curve 291. The side surface 220b can be bent with respect to the bottom surface 210 via a folding curve 291.

The recess 222 is provided at the center of the side surface 220. That is, the distance from the recess 222 to the edge of the side surface 220 on the +X direction side is equal to the distance from the recess 222 to the edge of the side surface 220 on the −X direction side. Specifically, the recess 222a is provided at the center of the side surface 220a. The recess 222b is provided at the center of the side surface 220b.

With reference to FIGS. 1 and 5(a), 5(b), 6(a) and 6(b), a method of assembling the packing device 300 will be described. 5(a), 5(b), 6(a) and 6(b) are schematic perspective views showing an assembling method of the packing device 300.

First, as shown in FIG. 5A, the outer member 100 is prepared.

Next, as shown in FIG. 5B, the side surface 120a and the side surface 120b are bent toward the +Z direction side with respect to the bottom surface 110.

Next, as shown in FIG. 6A, the inner member 200 is placed on the bottom surface 110 of the outer member 100 so that the inner member 200 is located inside the outer member 100.

Next, as shown in FIG. 6B, the upper surface 130a is bent toward the +X direction side with respect to the side surface 120a. Further, the protrusion 140a is bent toward the −Z direction with respect to the upper surface 130a so that the recess 144 of the protrusion 140a and the recess 222a are engaged with each other. Similarly, the protrusion 140b is bent toward the −Z direction with respect to the upper surface 130a so that the recess 144 of the protrusion 140b and the recess 222b are engaged with each other.

Next, from the state shown in FIG. 6B, the upper surface 130b is bent toward the −X direction side with respect to the side surface 120b. Further, the protrusion 140c is bent toward the −Z direction side with respect to the upper surface 130b so that the recess 144 of the protrusion 140c and the recess 222a are engaged with each other. Similarly, the protrusion 140d is bent toward the −Z direction with respect to the upper surface 130b so that the recess 144 of the protrusion 140d and the recess 222b are engaged with each other. As a result, the packing 300 is assembled as shown in FIG.

As described above with reference to FIGS. 1 to 6, in the packaging device 300, the first recess (recess 144) and the second recess (recess 222) engage with each other. Therefore, the upper surface 130a and the upper surface 130b are fixed to the side surface 220a and the side surface 220b. As a result, the packing device 300 can be easily assembled without using an adhesive tape.

Further, by engaging the first concave portion and the second concave portion, movement of the side surface 220a and the side surface 220b in the Y-axis direction can be suppressed. Therefore, it is possible to prevent the side surface 220a and the side surface 220b from being pushed inward.

Further, the first side surface (side surface 120a and side surface 120b) is orthogonal to the second side surface (side surface 220a and side surface 220b). Therefore, the first side surface and the second side surface form a side surface of the packing device 300. Therefore, the amount of corrugated board used can be reduced as compared with the case where the inner member is put in the outer box as in Patent Document 1.

The height of the main body portion 142 (length along the Z-axis direction) is equal to the height of the second side surface (side surface 220) (length along the Z-axis direction). Therefore, the tip of the protrusion 140 contacts the bottom surface 110. As a result, the packing 300 can be made stronger against the pressure from above.

[Embodiment 2]
The packing 300 according to the second embodiment of the present invention will be described with reference to FIG. 7. FIG. 7 is a schematic perspective view of the packing device 300 according to the second embodiment of the present invention. The packing tool 300 according to the second embodiment has the same configuration as the packing tool 300 according to the first embodiment, except that the height of the main body 142 is lower than the height of the side surface 220a. The description is omitted.

As shown in FIG. 7, in the present embodiment, the height of the main body portion 142 is lower than the height of the side surface 220a. Therefore, the tip of the protrusion 140 does not contact the bottom surface 110. In the present embodiment, the height of the side surface 220a is higher than the height of the main body 142, so that it is possible to package a relatively high-height object to be packed.

In the present embodiment as well, similar to the first embodiment, the packing device 300 can be easily assembled without using the adhesive tape.

[Third Embodiment]
A packing device 300 according to the third embodiment of the present invention will be described with reference to FIG. 8. FIG. 8 is a development view of the outer member 100 included in the packing device 300 according to the third embodiment of the present invention. The packing 300 according to the third embodiment has the same configuration as the packing 300 according to the first embodiment except that the outer member 100 has the connecting portion 148, and therefore, the description of the overlapping portions will be omitted.

As shown in FIG. 8, the outer member 100 includes a bottom surface 110, a side surface 120a, a side surface 120b, a top surface 130a, a top surface 130b, a protrusion 140a, a protrusion 140b, a protrusion 140c, and a protrusion 140d. In addition to and, a connection portion 148 is further provided.

The connecting portion 148 connects the protrusion 140a and the protrusion 140b. The protrusion 140a corresponds to an example of “first protrusion”. The protrusion 140b corresponds to an example of “second protrusion”. The connecting portion 148 can be bent along with the protruding portion 140a and the protruding portion 140b with respect to the upper surface 130a via a bending line 193.

Similarly, the connecting portion 148 connects the protrusion 140c and the protrusion 140d. The protrusion 140c corresponds to an example of "first protrusion". The protrusion 140d corresponds to an example of “second protrusion”. The connecting portion 148 can be bent along with the protruding portion 140c and the protruding portion 140d with respect to the upper surface 130b through a folding line 193.

The length of the connecting portion 148 along the X-axis direction is equal to the length of the side surface 120a and the side surface 120b along the X-axis direction. Therefore, when the packaging tool 300 is assembled, the tip of the connecting portion 148 contacts the bottom surface 110.

A method for assembling the packing device 300 will be described with reference to FIGS. 1, 5A, 5B, 6A, 8A, 9A, and 9B. 9A and 9B are schematic perspective views showing an assembling method of the packing device 300.

Similar to the method of assembling the packing device 300 described with reference to FIGS. 5A, 5B, and 6A, as shown in FIG. 9A, the inner member 200 is the outer member 100. The inner member 200 is placed on the bottom surface 110 of the outer member 100 so as to be located inside.

Next, as shown in FIG. 9B, the upper surface 130a is bent toward the +X direction side with respect to the side surface 120a. Furthermore, the protrusion 140a, the protrusion 140b, and the connecting portion 148 are bent toward the −Z direction side with respect to the upper surface 130a. At this time, the recess 144 of the protrusion 140a and the recess 222a are engaged with each other. Further, the recess 144 of the protrusion 140b and the recess 222b are engaged with each other. The connecting portion 148 contacts the bottom surface 210. Therefore, the upper surface 130a is supported by the connecting portion 148. As a result, it is possible to prevent the upper surface 130a from sinking.

Next, from the state shown in FIG. 9B, the upper surface 130b is bent toward the −X direction side with respect to the side surface 120b. Furthermore, the protrusion 140c, the protrusion 140d, and the connecting portion 148 are bent toward the −Z direction side with respect to the upper surface 130b. As a result, the packing 300 is assembled as shown in FIG. At this time, the recess 144 of the protrusion 140c and the recess 222a are engaged with each other. Further, the recess 144 of the protrusion 140d and the recess 222b are engaged with each other. The connecting portion 148 contacts the bottom surface 210. Therefore, the upper surface 130b is supported by the connecting portion 148. As a result, it is possible to prevent the upper surface 130b from sinking.

In the present embodiment as well, similar to the first to second embodiments, the packing device 300 can be easily assembled without using an adhesive tape.

A packing device 300 according to the fourth embodiment of the present invention will be described with reference to FIG. 10. FIG. 10 is a schematic perspective view of the packaging device 300 according to the fourth embodiment of the present invention. The packing tool 300 according to the fourth embodiment has the same configuration as the packing tool 300 according to the third embodiment except that the recess 222 is provided at a position displaced from the center of the side surface 220. The description is omitted.

As shown in FIG. 10, the protrusion 140a and the protrusion 140c are located at positions displaced from the center of the side surface 220a. Specifically, the protrusion 140a and the protrusion 140c are located at positions displaced from the center of the side surface 220a toward the −X direction side.

The inner member 200 will be described with reference to FIG. 11. FIG. 11 is a development view of the inner member 200. The inner member 200 shown in FIG. 11 has the same configuration as the inner member 200 shown in FIG. 4 except that the concave portion 222 is provided at a position displaced from the center of the side surface 220, and therefore the overlapping portions will be omitted. The description is omitted.

As shown in FIG. 11, the recess 222 is provided at a position displaced from the center of the side surface 220. Specifically, the recess 222a is provided at a position displaced from the center of the side surface 220a toward the −X direction side.

[Fifth Embodiment]
With reference to FIG. 12, the packing 300 which concerns on Embodiment 5 of this invention is demonstrated. FIG. 12 is a development view of the outer member 100 included in the packing device 300 according to the fifth embodiment of the present invention. The packaging tool 300 according to the fifth embodiment is implemented except that the protrusion 140 is provided only on one upper surface 130 of the two upper surfaces 130 and the insertion port 132 is provided on the other upper surface. Since the packaging tool 300 according to the first embodiment has the same configuration as that of the packaging tool 300, description of overlapping portions will be omitted.

As shown in FIG. 12, the outer member 100 has a bottom surface 110, a side surface 120a, a side surface 120b, an upper surface 130a, an upper surface 130b, a protrusion 140a, and a protrusion 140b. The upper surface 130a is provided with an insertion port 132a and an insertion port 132b. In this specification, the insertion port 132a and the insertion port 132b may be collectively referred to as the insertion port 132. The insertion port 132a and the insertion port 132b are openings. The insertion port 132a and the insertion port 132b have a rectangular shape. The insertion port 132a is provided at a position where the protrusion 140a can be inserted when the packaging tool 300 is assembled. The insertion port 132b is provided at a position into which the protrusion 140b can be inserted when the packaging tool 300 is assembled. The length of the insertion port 132 along the Y-axis direction is substantially equal to the length of the protrusion 140 along the Y-axis direction.

The inner member 200 will be described with reference to FIGS. 24 to 27. FIG. 24 is a perspective view showing the inner member 200 according to the ninth embodiment of the present invention. As shown in FIG. 24, the inner member 200 includes a plate (an example of a plate-shaped member) 10 and a film 30. In the present embodiment, the film 30 has a tubular shape. A film 30 is attached to the plate 10. Specifically, the film 30 is wound around the plate 10. The inner member 200 can pack the packing target object 50.

In the present embodiment, the plate 10 is, for example, one corrugated board having a thickness of about 5 mm. The film 30 is, for example, a polyethylene film having elasticity (flexibility). The film 30 is colorless and transparent, but is not limited thereto, and may be so-called translucent or opaque, or may be colored.

Note that FIG. 24 shows the developed state of the inner member 200. The size of the inner member 200 in the unfolded state is, for example, about 300 mm in the left-right direction and about 180 mm in the front-rear direction. The size of the inner member 200 is not limited to this, and is set according to the size of the packing target assumed as the packing target, various uses, and the like.

As shown in FIG. 24, the plate 10 is provided with three bending lines (folds; streaks) 21, 23 and 24. That is, one main bending line 21 and two sub bending lines 23 and 24 are formed. These folding lines 21, 23, 24 are formed by pressing a so-called creasing roller or creasing blade, for example. The folding lines 21, 23, 24 may be perforated.

The main bending line 21 is arranged at a position substantially in the center of the plate 10 in the front-rear direction and parallel to the left-right direction (parallel to the Y axis). The plate 10 can be easily bent with respect to the main bending line 21 so that both front and rear ends are displaced upward.

The sub-folding line 23 is arranged in the vicinity of the right end portion of the plate 10 in parallel to the front-rear direction (parallel to the X axis). In addition, the sub-bending line 24 is arranged in the vicinity of the left end portion of the plate 10 in parallel with the front-rear direction. The plate 10 can be easily bent with respect to the sub-folding line 23 so that the right end portion is displaced upward. The plate 10 can be easily bent with respect to the sub-folding line 24 so that the left end portion is displaced upward.

The plate 10 is provided with an arrangement surface 11 on which an object to be packed 50 (FIG. 25) to be packed is arranged, an adjacent surface 12 adjacent to the arrangement surface 11, and two side surfaces 220a and 220b. ing. The bottom surface 210 includes a part of the arrangement surface 11 and a part of the adjacent surface 12.

A main bending line 21 is arranged between the arrangement surface 11 and the adjacent surface 12. In other words, the arrangement surface 11 and the adjacent surface 12 are separated by the main bending line 21. The arrangement surface 11 is arranged on the front side of the plate 10, and the adjacent surface 12 is arranged on the rear side of the plate 10. The side surfaces 220a and 220b are partitioned so as to be adjacent to the arrangement surface 11 and the adjacent surface 12 via the sub-folding lines 23 and 24, respectively. The side surface 220a is a portion of the plate 10 on the right side of the sub-folding line 23. The side surface 220b is a portion of the plate 10 on the left side of the sub-folding line 24. In other words, the disposition surface 11 is a portion in front of the main bending line 21 and between the sub bending lines 23 and 24. The side surface 220a is provided with a recess 222a. A recess 222b is provided on the side surface 220b. In addition, the adjacent surface 12 is a portion that is behind the main bending line 21 and that is between the sub bending lines 23 and 24.

The plate 10 can be bent at the main bending line 21 between the adjacent surface 12 and the portion behind the side surfaces 220a, 220b with respect to the arrangement surface 11 and the portion in front of the side surfaces 220a, 220b.

The film 30 is arranged so as to mainly surround the arrangement surface 11 and the adjacent surface 12 of the plate 10. The film 30 is arranged so that the width direction (direction orthogonal to the circumferential direction) of the tubular film 30 is the left-right direction. In other words, the film 30 is wound around the plate 10 so that the main bending line 21 penetrates the inside of the cylinder formed by the film 30.

The film 30 may be attached to the plate 10 by various methods. For example, the film 30 is attached to the plate 10 by passing the plate 10 through the inside of the film 30 formed in advance in an annular shape. Further, for example, the film 30 is attached to the plate 10 by winding the film 30 around the plate 10 at least once and adhering the films 30 to each other using a wrapping machine or the like. With the film 30 attached to the plate 10, the plate 10 is foldable at each fold line 21, 23, 24.

In the present embodiment, the main bending line 21 is offset rearward of the center of the plate 10 in the front-rear direction. That is, the main bending line 21 is located at a position displaced from the center of the plate 10. The area of the arrangement surface 11 is larger than the area of the adjacent surface 12.

Next, a method of packing the packing target object 50 using the inner member 200 will be described. FIG. 25 is a sectional view of the inner member 200. In FIG. 25, the packaging using the inner member 200 is performed by sequentially following steps S11, S12, and S13 from top to bottom.

As shown in FIG. 25, the unfolded inner member 200 has a flat plate shape (S11). From this state, as shown by the upward arrow in the drawing, the plate 10 is bent at the main bending line 21 to bring the adjacent surface 12 close to the arrangement surface 11 and put in a bent state (a bending step).

Next, in a state where the plate 10 is bent, the packing target object 50 is placed in the gap A between the placement surface 11 and the film 30 (S12; placement step). The adjacent surface 12 is bent at the bending line 21 with respect to the arrangement surface 11 (hereinafter, also referred to as a bent state). When the inner member 200 is in the bent state, the object to be packed can be arranged in the gap A between the film 30 and the upper surface of the plate 10.

Then, as shown by the downward arrow in the figure, the adjacent surface 12 is expanded with respect to the arrangement surface 11 to be in the expanded state (S13). Then, the film 30 is stretched in a state of being in contact with the top of the packing target 50. As a result, the packing target 50 is pressed against the plate 10 (deployment step).

FIG. 26 is a perspective view showing the inner member 200 that has been packed and is in a developed state.

As shown in FIG. 26, when the unfolding step is performed, the front end portion, the rear end portion of the plate 10, the fold portion of the main bending line 21 portion, and the upper portion of the packing target object 50 are connected by a straight line in a side view. The length of the path becomes larger than that in the initially expanded state due to the arrangement of the packing target 50. The film 30 is stretched slightly while being in contact with the top of the packing target 50. Therefore, the packaging target 50 is pressed against the plate 10 by the film 30.

Here, in the present embodiment, when the expansion step is performed as described above, the side surfaces 220a and 220b may be bent by the auxiliary bending lines 23 and 24 with respect to the arrangement surface 11 so as to be in an upright state. it can. This allows the abutment surface 12 to be deployed relative to the placement surface 11, thereby tensioning the film 30. It should be noted that the side surfaces 220a and 220b may be raised after the expanding step is performed (starting step).

FIG. 27 is a perspective view showing a state where the side surfaces 220a and 220b are raised.

As shown in FIG. 27, since the sub-folding lines 23 and 24 intersect the main folding line 21 on the plate 10, when the side surfaces 220a and 220b are folded along the sub-folding lines 23 and 24, the plate 10 is arranged. The surface 11 and the adjacent surface 12 are held in the unfolded state (the unfolded state in which the adjacent surface 12 is substantially parallel to the placement surface 11). In other words, the side surfaces 220a and 220b cannot be bent unless the arrangement surface 11 and the adjacent surface 12 are substantially parallel to each other. In the present embodiment, since the two side surfaces 220a and 220b are provided on the plate 10 via the two sub-folding lines 23 and 24 that do not intersect with each other, both side surfaces 220a and 220b are bent and raised. By setting the state, the state in which the plate 10 is developed in the portion of the arrangement surface 11 and the adjacent surface 12 is reliably retained.
