Description

  The present invention relates to a package including a tray and a lid for closing the opening of the tray.

  Conventionally, packages that are heated by heating means such as a microwave oven while containing contents such as food are known. The package described in Patent Document 1 as an example includes a tray in which an opening is formed, and a lid that closes the opening. A hole is formed in the center in the longitudinal direction of the lid, and the hole is closed by an adhesive label. When the package is heated, the contents generate water vapor, the pressure in the space inside the tray rises, and the lid expands. When the lid expands, the adhesive label is peeled off, the space inside the tray is connected to the outside through the hole, and the water vapor is discharged to the outside.

JP 2008-253481 A

According to the above-mentioned package, for example, when an external force acts on the pressure-sensitive adhesive label at the distribution stage, the pressure-sensitive adhesive label peels off, and there is a possibility that foreign matter enters the space inside the tray through the hole.
An object of the present invention is to provide a package that can prevent foreign matters from entering a tray and can appropriately discharge water vapor.

  [1] One form of a package according to the present invention is a main body that forms a storage space that is a space in which contents can be stored, a tray that includes a flange that is formed around an opening of the main body, and a tray that is attached to the tray. And a lid that closes the opening of the main body, and the lid includes a penetrating portion that passes therethrough, and further includes a plurality of rotational positions or positions that can be attached to the tray, and the rotational position of the lid with respect to the main body Alternatively, when the position is set to the first position, the through portion is disposed at a portion closer to the edge of the flange than the planned seal portion of the flange where the seal with the lid is planned. When the rotational position or position of the lid with respect to the main body is set to the second position, the penetrating portion and the accommodation space are connected.

  According to the above package, after the contents are stored in the storage space of the tray, the sealing portion and the lid are sealed by sealing the planned sealing portion and the lid in a state where the rotation position or position of the lid with respect to the main body is set to the first position. A portion where the lid and the tray are sealed is formed between the edge of the opening and the penetrating portion. For this reason, it is prevented by the sealed part that a penetration part and an accommodation space connect, and a foreign material does not easily enter into the accommodation space of a tray from a penetration part.

  On the other hand, when the end user heats the package containing the contents, the seal between the lid and the tray is peeled off, the lid is once removed from the tray, and the rotational position or position of the lid with respect to the main body is set to the second position. . When the rotation position or position of the lid with respect to the main body is set to the second position, the penetration part and the accommodation space are connected, so that the water vapor generated from the contents by heating the package is appropriate through the penetration part. Discharged to the outside.

  [2] According to an example of the package, the flange includes a concave portion that opens to a front side of the flange and forms a concave space that is a space connected to the accommodation space, and the rotational position or position of the lid with respect to the main body Is set at the second position, the penetration portion and the recessed space are connected to each other, whereby the penetration portion and the accommodation space are connected.

  According to the above-described package, when the position of the lid with respect to the main body is set to the second position, since the penetrating portion faces the concave portion formed in the flange, there is a concave space in the portion facing the penetrating portion. . For this reason, the water vapor that is about to be discharged to the outside through the recessed space and the through portion from the housing space is less likely to stay near the through portion, and the water vapor is more likely to be discharged more appropriately.

[3] According to an example of the package, the flange is formed around the entire opening of the main body.
When the package in which the contents are stored in the tray is heated, the water vapor is discharged from the storage space of the tray through the penetration portion. For this reason, the part in which the recessed part which faces the penetration part among flanges is formed has high temperature. According to the above package, since the flange is formed around the entire opening of the main body, the end user can select a portion of the package flange other than the portion where the recess is formed, that is, relatively A portion having a low temperature can be gripped. For this reason, it is easy to carry a package.

  [4] According to an example of the package, the contents are accommodated in the accommodation space, the rotational position or position of the lid with respect to the main body is set to the first position, and the planned sealing portion and the lid are It is sealed.

  According to the said package, since the said package of [1]-[3] is used, it is difficult for a foreign material to enter into the storage space of a tray, and water vapor | steam can be discharged | emitted appropriately.

  According to the said package, a foreign material cannot enter a tray easily and water vapor | steam can be discharged | emitted appropriately.

(First embodiment)
As shown in FIG. 1 or 2, the package 1 before the contents are accommodated includes a tray 10 and a lid 50 that can be attached to the tray 10. 1 and 2 show the package 1 in a state where the tray 10 and the lid 50 are not sealed.

  The tray 10 includes a main body 20 that forms a storage space 21 that is a space in which contents can be stored, and a flange 30 that is formed around the opening 11 of the main body 20. As an example, the tray 10 includes a three-layer structure in which an outermost layer, an intermediate layer, and an innermost layer are stacked. An example of the material constituting the outermost layer is polypropylene. An example of the material constituting the intermediate layer is eval resin. An example of the material constituting the innermost layer is polypropylene. The main body 20 has a hollow rectangular parallelepiped shape with an open top.

  The flange 30 is formed all around the opening 11. The flange 30 includes a first portion 31 formed at one end portion in the longitudinal direction of the main body 20, a second portion 32 formed at the other end portion in the longitudinal direction of the main body 20, and a first portion A pair of third portions 33 that connect the first portion 31 and the second portion 32 to each other.

  The first portion 31 faces the second portion 32 through the main body 20 in the longitudinal direction of the main body 20 and extends outward from the edge of the opening 11. The area of the first portion 31 is larger than the area of the second portion 32.

  The second portion 32 extends outward from the edge of the opening 11 to form a recess 32A. The recess 32 </ b> A opens on the surface of the flange 30 to form a recess space 32 </ b> B that is a space connected to the accommodation space 21. The opening of the recess 32 </ b> A is connected to the opening 11 of the main body 20. The pair of third portions 33 oppose each other via the main body 20 in the short direction of the main body 20.

  A two-dot chain line shown in FIG. 1 is a region formed on the flange 30 and where a planned sealing portion 40 which is a portion sealed with the lid 50 is formed. The planned sealing portion 40 is formed around the opening of the recess 32 </ b> A and the periphery of the opening 11 of the main body 20.

  As shown in FIG. 1, the lid 50 has an elliptical shape in plan view, and a through portion 51 penetrating in the height direction of the package 1 is formed. As an example, the lid 50 has a three-layer structure in which an outermost layer, an intermediate layer, and an innermost layer are stacked. An example of the material constituting the outermost layer is polypropylene. An example of the material constituting the intermediate layer is eval resin. An example of the material constituting the innermost layer is an easy peel resin that can be easily sealed with polypropylene constituting the innermost layer of the tray 10. The through portion 51 is a circular hole in the plan view of the lid 50.

  The lid 50 includes a plurality of rotational positions that can be attached to the tray 10. The rotational position includes a first position and a second position. The end user changes the rotational position of the lid 50 with respect to the main body 20 by rotating the lid 50 about the height axis of the tray 10.

  When the rotation position of the lid 50 with respect to the main body 20 is set to the first position (see FIGS. 1 and 2), the seal 30 is a portion of the flange 30 where the seal with the lid 50 is planned. Also, the penetrating portion 51 is disposed in a portion near the edge of the flange 30. When the position of the lid 50 with respect to the main body 20 is set to the first position, the through portion 51 faces the first portion 31 of the flange 30.

  When the rotation position of the lid 50 with respect to the main body 20 is set to the second position (see FIGS. 7 and 8), the penetrating part 51 and the accommodation space 21 are connected. When the position of the lid 50 with respect to the main body 20 is set to the second position, the penetrating portion 51 faces the concave portion 32 </ b> A formed in the second portion 32 of the flange 30.

An example of a method for filling the contents into the package 1 will be described.
As shown in FIG. 3, the lid 50 is removed from the tray 10, and the liquid content 110 is stored in the storage space 21 of the tray 10. An example of the liquid content 110 is a seasoning such as a sauce.

  As shown in FIG. 4 or 5, after the liquid content 110 is accommodated in the accommodation space 21 of the tray 10, the lid 50 is placed in the tray 10 so that the rotational position of the lid 50 with respect to the main body 20 becomes the first position. The sealing process is performed on the portion of the lid 50 corresponding to the planned sealing portion 40 and the planned sealing portion 40. For this reason, the seal part 60 which is the part by which the lid | cover 50 and the tray 10 were sealed in the part which was the seal | sticker planned part 40 is formed. The seal portion 60 is also formed between the edge of the opening 11 and the through portion 51. For this reason, the seal portion 60 prevents the penetration portion 51 of the lid 50 and the accommodation space 21 of the tray 10 from being connected. The package 1 in a state where the seal portion 60 is formed is displayed in, for example, a convenience store.

The operation will be described together with an example of how to use the package 1.
As shown in FIG. 6, the end user purchases the package 1 in which the liquid content 110 is accommodated and the seal portion 60 is formed, and before the package 1 is heated by heating means (not shown) such as a microwave oven. Remove the lid 50 from the tray 10 once. For this reason, the seal part 60 peels. After removing the lid 50 from the tray 10, the end user adds the solid content 120 to the liquid content 110. An example of the solid content 120 is meat and vegetables.

  As shown in FIG. 7 or FIG. 8, after the end user adds the solid content 120 to the liquid content 110, the end user trays the lid 50 so that the rotational position of the lid 50 with respect to the main body 20 is the second position. Attach to 10. Thereafter, the end user heats the package 1 by a heating means. When the package 1 is heated, the liquid content 110 and the solid content 120 generate water vapor. When the rotation position of the lid 50 with respect to the main body 20 is set to the second position, the penetrating part 51 and the accommodation space 21 are connected, so that water vapor generated from the liquid content 110 and the solid content 120 passes through the penetrating part 51. Are appropriately discharged to the outside. After the heating of the package 1 is finished, the end user grasps, for example, the first portion 31 of the flange 30 and takes out the package 1 from the heating means.

According to the package 1, the following effects can be obtained.
(1) After the liquid content 110 is stored in the storage space 21 of the tray 10, the planned sealing portion 40 and the cover 50 are sealed in a state where the rotation position of the cover 50 with respect to the main body 20 is set to the first position. A seal portion 60 is formed between the edge of the opening 11 of the tray 10 and the penetrating portion 51. For this reason, the penetration part 51 and the accommodation space 21 are prevented from being connected by the seal part 60, and foreign matter does not enter the accommodation space 21 of the tray 10 from the penetration part 51.

  (2) When the rotation position of the lid 50 with respect to the main body 20 is set to the second position, the penetrating part 51 and the accommodation space 21 are connected, so that the liquid content 110 and the solid form are heated by heating the package 1. The water vapor generated from the contents 120 is appropriately discharged to the outside through the penetration part 51.

  (3) When the position of the lid 50 with respect to the main body 20 is set to the second position, the through portion 51 faces the concave portion 32A formed in the flange 30, so the concave portion 32A is formed in the portion facing the through portion 51. The recessed space 32B exists. For this reason, the water vapor that is about to be discharged from the accommodating space 21 to the outside through the recessed space 32B and the through portion 51 is unlikely to stay in the vicinity of the through portion 51, and the water vapor is more easily discharged.

  (4) When the package 1 in which the liquid content 110 and the solid content 120 are accommodated in the tray 10 is heated, the water vapor is discharged from the accommodation space 21 of the tray 10 through the penetrating portion 51. For this reason, the 2nd part 32 in which the recessed part 32A facing the penetration part 51 of the flange 30 is formed has high temperature. Since the package 30 has the flange 30 formed around the entire periphery of the opening 11 of the main body 20, the end user can select a portion other than the portion where the recess 32A is formed in the flange 30 of the package 1 after heating. It is possible to grip a portion having a relatively low temperature. For this reason, the package 1 is easy to carry.

  (5) Since the area of the first portion 31 is larger than the area of the second portion 32, the end user can more easily grip the first portion 31 that is a relatively low temperature portion of the flange 30.

  (6) Since the planned sealing portion 40 is formed around the entire periphery of the opening 11, the liquid content 110 is accommodated in the accommodating space 21, and the rotational position of the lid 50 with respect to the main body 20 is set to the first position. By sealing the planned sealing portion 40 and the lid 50 in the state, the sealing portion 60 is formed around the entire opening 11. For this reason, the entire periphery of the opening 11 and the lid 50 are sealed, and foreign matter does not enter the accommodation space 21 of the tray 10.

When the position of the lid 450 with respect to the main body 420 is set to the second position, the through portion 451 faces the recess 432 of the flange 330, and the two protrusions 452 of the lid 450 are inserted into the two holes 434 of the flange 430. Is done.

The operation will be described together with an example of how to use the package 1.
As shown in FIG. 19, the package 1 has two protrusions 452 so that the position of the lid 450 with respect to the main body 420 becomes the first position after the liquid content 110 is accommodated in the accommodation space 421 of the tray 410. The lid 450 is attached to the tray 410 by being inserted into 433, and the sealing process is performed on the planned sealing portion 440. Therefore, a seal portion 460 that is a portion where the lid 450 and the tray 410 are sealed is formed in the portion that is the planned seal portion 440. Since the seal portion 460 is also formed between the edge of the opening 411 and the through portion 451, the seal portion 460 prevents the through portion 451 of the lid 450 from being connected to the accommodation space 421 of the tray 410.

  After the end user purchases the package 1 in which the liquid content 110 is accommodated and the seal portion 460 is formed, the lid 450 is removed from the tray 410 before the package 1 is heated by heating means (not shown) such as a microwave oven. Remove it once. For this reason, the seal part 460 peels.

  As shown in FIG. 20, after the end user adds the solid content 120 to the liquid content 110, the end user shifts the lid 450 in the longitudinal direction of the main body 420, and the position of the lid 450 with respect to the main body 420 is the second position. In such a manner, the two protrusions 452 of the lid 450 are inserted into the holes 434 and attached to the tray 410. Thereafter, the end user heats the package 1 by a heating means. When the package 1 is heated, the liquid content 110 and the solid content 120 generate water vapor. When the position of the lid 450 with respect to the main body 420 is set to the second position, the penetrating portion 451 and the accommodation space 421 are connected to each other, so that water vapor generated from the liquid content 110 and the solid content 120 passes through the penetrating portion 451. Are appropriately discharged to the outside. After the heating of the package 1 is completed, the end user grasps, for example, the flat portion 431 of the flange 430 and takes out the package 1 from the heating means. According to the package 1, the effects according to the above (1) to (4), (6), and (7) can be obtained.
