  In the above-described packaging container, the opening formed by the wall plate is covered by a part of the lid when the lid is closed. For this reason, when the packaging container is viewed in a plan view, the inside of the packaging container cannot be seen in a partial region of the lid. The present specification provides a technique for making the inside of a packaging container easier to see.

  The technology disclosed in the present specification relates to a packaging container. The packaging container includes a container body including a bottom portion, a side wall portion extending from the bottom portion, and a transparent film for closing an opening formed by the side wall portion, and the transparent film covers the opening. In the state, the opening is not closed by a member different from the transparent film. According to the above configuration, when the transparent film blocks the opening, the opening is not closed by a member different from the transparent film. Therefore, the inside of the packaging container is easy to see.

  One end of the transparent film is fixed to the container main body, and the packaging container is a fixing part to which the other end of the transparent film is further fixed, and is separate from the container main body. It may include the fixing part. According to this configuration, the user can hold the fixing portion and change from a state in which the transparent film does not block the opening to a state in which the transparent film is closing the opening.

  The container body may include a receiving structure for receiving the fixing portion. According to this configuration, the fixing portion can be fixed to the container main body by using the receiving structure, so that the operation of bonding the fixing portion to the container main body becomes unnecessary. Therefore, user convenience is improved.

  The receiving structure may be provided on an outer bottom surface of the container body. According to this configuration, the fixing portion is fixed to the outer bottom surface of the container body. Therefore, the appearance of the packaging container is not impaired.

  The transparent film has a rectangular shape, the one end and the other end constitute two opposing sides of the transparent film, and in a state where the transparent film covers the opening, the transparent film A part of each of the other two sides may be supported by the side wall of the container body. According to this configuration, it is possible to suppress the transparent film from being loosened while the transparent film is blocking the opening.

  The side wall portion may include a first portion extending upward from the bottom portion, and a second portion extending horizontally from an upper end of the first portion toward the inside of the container body. According to this configuration, when another packaging container is overlaid on the packaging container, the other packaging container is supported by the second portion. Therefore, the packaging containers can be stably stacked.

  In the deployable body for molding the packaging container, the fixing portion may be fixed to a deployable body for molding the container body.

(First embodiment)
The structure of the packaging container 100 of the first embodiment will be described with reference to FIGS. The packaging container 100 is a container for accommodating foods, daily necessities and the like. The packaging container 100 is particularly useful for containing a gift. As shown in FIG. 1, the packaging container 100 has a substantially rectangular parallelepiped shape, and includes a container body 10 and a transparent film 20. In the drawings, the transparent film 20 is hatched for convenience.

  The container body 10 is formed of, for example, corrugated paper, but may be formed of paper other than corrugated paper. Further, the container body 10 is not limited to paper, and may be formed from plastic or the like.

  The container main body 10 includes a bottom 11, a pair of long side walls 12 and 14 extending upward from the bottom 11, and a pair of short side walls 16 and 18 extending upward from the bottom 11. An opening 10 a of the container body 10 is formed by the side walls 12, 14, 16, 18. The opening 10a is closed by the transparent film 20. In a state where the transparent film 20 closes the opening 10a (hereinafter, referred to as a “closed state”), the opening 10a is not closed by a member different from the transparent film 20. Therefore, the inside of the packaging container 100 is easy to see.

  As shown in the development of FIG. 5, the transparent film 20 is a colorless and transparent film having a rectangular shape. The transparent film 20 is not limited to a colorless and transparent film, but may be a colored and transparent film. Further, the transparent film 20 may be a translucent film. Generally speaking, the transparent film 20 only needs to be transparent so that the inside of the packaging container 100 can be seen. Further, the transparent film 20 only needs to have a shape corresponding to the shape of the container body 10, and for example, may have a square shape.

  FIG. 2 is a plan view of the packaging container 100 in a state where the transparent film 20 does not block the opening 10a (hereinafter, referred to as “non-blocking state”). One end (that is, the left end in FIG. 2) of the transparent film 20 is fixed (adhered in the present embodiment) to the container body 10. The packaging container 100 includes a fixing portion 30 that is separate from the container body 10. The fixing portion 30 is made of the same material as the container body 10 in this embodiment, but may be made of a material different from that of the container body 10 in a modified example. The other end of the transparent film 20 is fixed (adhered in this embodiment) to the fixing part 30. The fixing portion 30 extends from the center of the first portion 30a to which the transparent film 20 is fixed, and the right direction in FIG. 2 (that is, the direction opposite to the direction in which the transparent film 20 exists) from the center of the first portion 30a. A second portion 30b. As will be described later in detail, a closed state is realized by inserting the second portion 30b of the fixing portion 30 into a slit provided on the outer bottom surface of the container body 10. The user can change the packaging container 100 from the non-closed state to the closed state by holding the fixing unit 30. In particular, since the transparent film 20 is not fixed to the second portion 30b of the fixing portion 30, if the user holds the second portion 30b, it is possible to prevent the transparent film 20 from being stained by a fingerprint or the like.

  FIG. 3 shows a bottom view of the packaging container 100 in the non-closed state. The bottom 11 has a so-called double bottom structure. That is, the bottom portion 11 includes a plate 11a (see FIG. 2) forming the inner bottom surface of the container body 10 and a plate 11b forming the outer bottom surface of the container body 10. One end 20a of the transparent film 20 (that is, an end region forming one short side of the transparent film 20) is adhered to the plate 11b. The hatching in the area indicated by reference numeral 20a indicates a portion of the transparent film 20 that is adhered to the plate 11b. Since the adhesive portion (that is, reference numeral 20a) of the transparent film 20 is provided on the outer bottom surface of the container body 10, the adhesive portion is not visible when the packaging container 100 is viewed in a plan view. For this reason, the appearance of the packaging container 100 is not impaired.

  The plate 11b is provided with a slit 11c. The slit 11c is not provided on the plate 11a. That is, the slit 11 c does not penetrate the bottom 11. As a result, the slit 11c is not formed on the inner bottom surface of the container main body 10, so that when the second portion 30b of the fixing part 30 is inserted into the slit 11c, the fixing part 30 does not protrude inside the container main body 10. As a result, it is possible to prevent the object accommodated in the container body 10 from being damaged by the fixing portion 30. In addition, in a modification, the slit 11c may penetrate the bottom part 11. In the present embodiment, the slit 11c is an example of the “receiving structure”.

  FIG. 4 shows a bottom view of the packaging container 100 in the closed state. The other end portion 20 b of the transparent film 20 (that is, an end region forming the other short side of the transparent film 20) is adhered to the first portion 30 a of the fixing portion 30. The hatching in the area indicated by reference numeral 20b indicates a portion of the transparent film 20 that is adhered to the fixing unit 30.

  The fixing portion 30 is fixed to the container body 10 by inserting the second portion 30b of the fixing portion 30 into the slit 11c. The work of bonding the fixing portion 30 to the container body 10 is unnecessary, and the convenience for the user is improved. Further, a slit 11c is provided on the outer bottom surface of the container body 10, and the fixing portion 30 is inserted therein. Therefore, when the packaging container 100 is viewed in a plan view, the slit 11c and the fixing portion 30 are not visible. Therefore, the appearance of the packaging container 100 is not impaired.

  As described above, the one end 20a and the other end 20b of the transparent film 20 form two short sides (that is, two opposite sides) of the transparent film 20. As shown in FIG. 1, in the closed packaging container 100, part of one long side 20 c of the transparent film 20 is located between the outer side surface 16 a and the inner side surface 16 c of the short side wall portion 16. I do. Further, a part of the other long side 20 d of the transparent film 20 is located between the outer side surface 18 a and the inner side surface 18 c of the short side wall portion 18. Therefore, a part of each of the two long sides 20 c and 20 d of the transparent film 20 is supported by the short side wall portions 16 and 18. Thereby, the loosening of the transparent film 20 can be suppressed in the closed state.

  FIG. 5 shows a development body 60 for molding the packaging container 100. The structure of the packaging container 100 will be described in more detail with reference to FIG. In FIG. 5, the broken line is shown by a broken line. The deployable body 60 includes a deployable body 62 for molding the container body 10, the fixing unit 30, and the transparent film 20.

  The deployable body 62 includes a plurality of plates 16a to 16h for forming the short side wall portion 16. The plate 16d is bent 90 degrees toward the near side of the drawing sheet (hereinafter, simply referred to as “front side”) in the folding curve 110. The plate 16c is bent 90 degrees in the folding curve 111 toward the back side of the paper (hereinafter simply referred to as “back side”). The plate 16b is bent 90 degrees to the back side in the folding curve 112. The plate 16a is bent 90 degrees to the back side in the folding curve 113. The plate 16e is bent 90 degrees to the near side at the folding curve 114, and the plate 16f is bent 90 degrees to the back side at the folding curve 115. The plate 16g is bent 90 degrees to the near side in the folding curve 116, and the plate 16h is bent 90 degrees to the back side in the folding curve 117. Thereby, the short side wall portion 16 is formed. The plate 16b forms the upper end surface of the short side wall portion 16, and supports a part of the long side 20c of the transparent film 20 in the closed state. Although a reference numeral and description are omitted, the short side wall portion 18 is formed in the same manner as the short side wall portion 16.

  The deployable body 62 further includes a plurality of plates 14a to 14d for forming the long side wall portion 14. The plate 14d is bent 90 degrees to the near side in the folding curve 120. The plate 14c is bent 90 degrees to the back side in the folding curve 121. The plate 14c is provided with two holes 15. The plate 14b is bent 90 degrees to the back side in the folding curve 122. The plate 14a is bent 90 degrees to the back side in the folding curve 123. At this time, the plates 16g and 16h of the short side wall portion 16 are sandwiched between the plates 14a and 14c (the same applies to the short side wall portion 18). Thereby, the long side wall portion 14 is formed.

  In the unfolded body 60, the first portion 30a of the fixing portion 30 is fixed to one end of the unfolded body 62 (the upper end in FIG. 5, more specifically, the plate 11d). As a result, since the deployable body main body 62 and the fixing portion 30 do not separate from each other in the deployable body 60, the deployable body 60 is easily stored. Further, a break line 32 is provided between the first portion 30a of the fixing portion 30 and the deployable body main body 62 (more specifically, the plate 11d). Thereby, when molding the packaging container 100, the gap between the deployable body main body 62 and the fixing portion 30 can be easily broken.

  In the unfolded body 60, the transparent film 20 is disposed so as to overlap the plates 11a, 11b, 11d, 12a to 12c, and the first portion 30a of the fixing portion 30. One end 20a of the transparent film 20 is fixed to the plate 11b, and the other end 20b of the transparent film 20 is fixed to the first portion 30a of the fixing portion 30. Since the transparent film 20 is not bent but maintained in a rectangular shape, the developed body 60 can be easily stored.

  The deployable body 62 further includes a plurality of plates 12a to 12c for forming the long side wall portion 12. After breaking between the deployment body main body 62 and the fixing portion 30 at the break line 32, the long side wall portion 12 is formed. The plate 12c is bent 90 degrees to the back side in the folding curve 130. The plate 12b is bent 90 degrees to the back side in the folding curve 131. The plate 12a is bent 90 degrees to the back side in the folding curve 132. At this time, the plates 16e and 16f of the short side wall portion 16 are sandwiched between the plates 12a and 12c (the same applies to the short side wall portion 18). Thereby, the long side wall portion 12 is formed.

  The deployable body 62 further includes a plurality of plates 11a, 11b, 11d for forming the bottom portion 11. The plate 11d is bent toward the near side at the folding curve 140. The plate 11a is bent 90 degrees to the near side in the folding curve 141. Then, the two plates 11d are inserted into the two holes 15 of the plate 14c of the long side wall portion 14. Thus, the plate 11a forms the inner bottom surface of the container body 10, the plate 11b forms the outer bottom surface of the container body 10, and the bottom 11 has a double bottom structure. Thereby, the container body 10 is formed.

  After molding the container body 10, the user stores the object in the container body 10. Then, the user inserts the second portion 30b of the fixing portion 30 into the slit 11c provided on the outer bottom surface of the container body 10. Thus, the closed packaging container 100 is realized.

(Second embodiment)
Next, the structure of the packaging container 200 of the second embodiment will be described with reference to FIGS. In the present embodiment, the bottom 211 of the container body 210 is different from the bottom 11 of the container body 10 of the first embodiment. Each part 212 to 220 and 230 of the packaging container 200 has substantially the same configuration as each part 12 to 20 and 30 of the packaging container 100 of the first embodiment. Therefore, only the details of the bottom part 211 will be described below.

  FIG. 6 shows a perspective view of the packaging container 200 in a closed state. The bottom part 211 has a so-called double bottom structure. That is, the bottom part 211 includes a plate 211a (see FIG. 9) forming the inner bottom surface of the container body 210, and a plate 211b (see FIG. 9) forming the outer bottom surface of the container body 210.

  The plate 211a of the bottom part 211 has two holding parts 213a and 213b. The holding portions 213a and 213b are members for holding an object accommodated in the container body 210, and can be bent at folding curves 250 to 259. FIG. 7 shows the packaging container 200 in a state where the object Ob1 is held by the holding units 213a and 213b (hereinafter, referred to as a “holding state”). In FIG. 7, illustration of the transparent film 220 is omitted for easy understanding. The holding portion 213b is bent 90 degrees toward the opening 210a at the folding curve 257. Although not visible in FIG. 7, the holding portion 213a (see FIG. 6) is also bent 90 degrees toward the opening 210a at the folding curve 251. Accordingly, the object Ob1 is held by the holding units 213a and 213b by sandwiching both ends of the object Ob1 by the holding units 213a and 213b. As a result, for example, even when the packaging container 200 is placed with the short side wall portion 216 as the bottom surface, the position of the object Ob1 can be held. Therefore, the degree of freedom in displaying the packaging container 200 is improved. FIG. 7 is an example of the packaging container 200 in a holding state. The holding portions 213a and 213b can hold objects of various shapes by being bent at other portions of the folding curves 250 to 259. .

  FIG. 8 shows the packaging container 200 in a holding state different from that of FIG. In FIG. 8, the illustration of the transparent film 220 is omitted for easy understanding.

Thereby, the holding part 213a forms an opening for receiving an object. The same applies to the holding unit 213b. By inserting the objects Ob2 and Ob3 into the openings of the holding units 213a and 213b, the objects Ob2 and Ob3 are held by the holding units 213a and 213b. In the present embodiment, the holding portions 213a and 213b have a square shape, but may have another shape (for example, a rectangular shape), and may have a shape corresponding to an object to be held.

  FIG. 9 shows a developed body 260 for molding the packaging container 200. In FIG. 9, broken lines are shown by broken lines. The deployable body 260 includes a deployable body main body 262 for molding the container body 210, a fixing portion 230, and a transparent film 220.

  The deployable body 262 includes a plurality of plates 211a, 211b, 211d to 211g for forming the bottom 211. The plate 211d is bent 90 degrees to the near side in the folding curve 240. The plates 211e to 211g are bent 90 degrees to the back side at the folding curves 241 to 243, respectively. The plate 211a is bent 90 degrees to the near side at the folding curve 244. Then, the two plates 211d are inserted into the two holes 215 of the plate 214c of the long side wall portion 214. Thus, the plate 211a forms the inner bottom surface of the container body 210, the plate 211b forms the outer bottom surface of the container body 210, and the bottom 211 has a double bottom structure. In the present embodiment, a space is created between the plates 211a and 211b by the plates 211e to 211g. That is, the bottom 11 has a so-called raised bottom structure. When the bottom 211 is formed, the container body 210 is formed.

  After molding the container main body 210, the user stores the object Ob1 (or 2, 3) in the container main body 210 and fixes the object Ob1 (or 2, 3) using the holding portions 213a, 213b. Then, the user inserts the fixing portion 230 into the slit 211c provided on the outer bottom surface of the container body 10. Thereby, the closed packaging container 200 is realized.

Then, the user inserts the second portion 330b of the fixing portion 330 into the slit 311c provided on the outer bottom surface of the container body 310. Thus, the closed packaging container 300 is realized.

  As mentioned above, although embodiment of this invention was described in detail, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and alterations of the specific examples illustrated above.

(1) The packaging container 100 does not have to include the fixing unit 30. That is, the other end 20b of the transparent film 20 does not have to be fixed to another member, as long as at least one end 20a of the transparent film 20 is fixed to the container body 10.

(2) The slit 11c may not be provided. In this case, the packaging container 100 in the closed state may be realized by bonding the fixing portion 30 to the container body 10.

(3) The slit 11c may not be provided on the plate 11b of the bottom part 11, but may be provided on the long side wall part 14, for example. Also in this modification, the operation of bonding the fixing portion 30 to the container body 10 is unnecessary, and the convenience for the user is improved.

(4) In the deployable body 60, the fixing portion 30 may not be fixed to the deployable body main body 62.

(5) The shape of the packaging container 100 is not limited to a rectangular parallelepiped, and may be, for example, a cube, a triangular prism, or a pentagonal or more polygonal prism.

  Further, the technical elements described in the present specification or the drawings exert technical utility singly or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.
