Description

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

  2. Description of the Related Art Conventionally, there has been known a package which is heated by a heating means such as a microwave oven in a state in which contents such as food are stored. The package described in Patent Document 1 as an example thereof 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 steam, the pressure in the space inside the tray increases, and the lid expands. When the lid expands, the pressure-sensitive adhesive label is peeled off, the space inside the tray is connected to the outside via the hole, and 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 may be peeled off, and foreign matter may enter the space inside the tray via the hole.
It is an object of the present invention to provide a package that makes it difficult for foreign matter to enter a tray and that can appropriately discharge water vapor.

  [1] One embodiment of a package according to the present invention is a tray including a main body forming a storage space that is a space capable of storing contents, a flange formed around an opening of the main body, and a tray attached to the tray. A lid that closes the opening of the main body by being provided, the lid is formed at a portion including an edge of the lid, protrudes toward the front side of the lid, and faces toward the outside and the bottom side of the lid, respectively. It comprises a hollow convex portion that opens, and further comprises a plurality of rotational positions or positions attachable to the tray, and when the rotational position or position of the lid with respect to the main body is set to a first position, The convex portion is arranged at a portion closer to the edge of the flange than a portion to be sealed, which is a portion where sealing with the lid is scheduled, and the rotational position or position of the lid with respect to the main body. If is set to the second position, the convex portion space and the receiving space is a space formed in said convex portion leads.

  According to the above-mentioned package, after the contents are accommodated in the accommodation space of the tray, the portion to be sealed and the lid are sealed in a state where the rotation position or the position of the lid with respect to the main body is set to the first position, whereby the tray A portion where the lid and the tray are sealed is formed between the edge of the opening and the convex portion. For this reason, the connection between the convex space and the housing space is prevented by the sealed portion, and foreign matter is less likely to enter the housing space of the tray from the portion opened outside the convex portion.

  On the other hand, when heating the package containing the contents, the end user peels off the seal between the lid and the tray, once removes the lid from the tray, and sets the rotational position or position of the lid with respect to the main body to the second position. . When the rotation position or the position of the lid with respect to the main body is set to the second position, since the convex space and the housing space are connected, water vapor generated from the contents by heating the package is outside the convex. It is appropriately discharged to the outside through the portion that opens toward the outside.

  [2] According to an example of the package, the flange includes a concave portion that opens on a front side of the flange and forms a concave space that is a space connected to the housing space, and the rotational position or the position of the lid with respect to the main body. Is set to the second position, the projection space and the accommodation space are connected by connecting the projection space and the recess space.

  According to the above package, when the position of the lid with respect to the main body is set to the second position, the convex portion faces the concave portion formed on the flange, so that there is a concave space in the portion facing the convex portion. . For this reason, the water vapor that is going to be discharged to the outside from the accommodation space through the concave space, the convex space, and the portion that opens outside the convex portion is unlikely to stay near the convex portion, and the water vapor is more appropriate. Easy to be discharged.

[3] According to one example of the package, the flange is formed entirely around the opening of the main body.
When the package in which the contents are stored in the tray is heated, water vapor is discharged from the storage space of the tray through a portion that opens outside the convex portion. Therefore, the temperature of the portion of the flange where the concave portion facing the convex portion is formed is high. According to the package, since the flange is formed entirely around the opening of the main body, the end user can use a portion of the flange of the heated package other than the portion where the concave portion is formed, that is, a relatively small portion. A part with a low temperature can be gripped. Therefore, the package is easy to carry.

  [4] According to an example of the package, contents are accommodated in the accommodation space, a rotation position or a position of the lid with respect to the main body is set to the first position, and the scheduled sealing portion and the lid are Sealed.

  According to the above package, since the packages of [1] to [3] are used, foreign matter hardly enters the accommodation space of the tray, and water vapor can be appropriately discharged.

  According to the above-mentioned package, it is difficult for foreign matters to enter the tray, and the steam can be appropriately discharged.

(1st Embodiment)
As shown in FIG. 1 or FIG. 2, the package 1 before the contents are stored includes a tray 10 and a lid 50 attachable 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 forming a storage space 21 that is a space capable of storing contents, and a flange 30 formed around the opening 11 of the main body 20. As an example, the tray 10 has a three-layer structure in which an outermost layer, an intermediate layer, and an innermost layer are stacked. One example of a material constituting the outermost layer is polypropylene. One example of a material forming the intermediate layer is an evar resin. One example of a material constituting the innermost layer is polypropylene. The main body 20 has a hollow rectangular parallelepiped shape whose upper part is open.

  The flange 30 is formed entirely around the opening 11. The flange 30 includes a first portion 31 formed at one longitudinal end of the main body 20, a second portion 32 formed at the other longitudinal end of the main body 20, and a first portion 31. And a pair of third portions 33 connecting the first portion 31 and the second portion 32.

  The first portion 31 faces the second portion 32 via 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 part 31 is larger than the area of the second part 32.

  The second portion 32 extends outward from the edge of the opening 11 and has a recess 32A. The concave portion 32A opens on the surface of the flange 30 to form a concave space 32B that is a space connected to the housing space 21. The opening of the concave portion 32A is connected to the opening 11 of the main body 20. The pair of third portions 33 face each other with the main body 20 interposed therebetween in the lateral direction of the main body 20.

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

  As shown in FIG. 1, the lid 50 has an elliptical shape in a plan view, and has a convex portion 51. The lid 50 has, for example, a three-layer structure in which an outermost layer, an intermediate layer, and an innermost layer are stacked. One example of a material constituting the outermost layer is polypropylene. One example of a material forming the intermediate layer is an evar resin. An example of a material constituting the innermost layer is an easy-peelable resin which can be easily sealed with the polypropylene constituting the innermost layer of the tray 10.

  As shown in FIG. 3, the convex portion 51 is formed at a portion including the edge 50 </ b> A of the lid 50, protrudes toward the front side of the lid 50, and opens toward the outside and the bottom side of the lid 50. It is.

  The lid 50 has a plurality of rotation positions that can be attached to the tray 10. The rotation 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 around an axis in the height direction 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 sealing portion 40, which is a portion of the flange 30 where sealing with the lid 50 is scheduled, is performed. The protruding portion 51 is also arranged 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 convex portion 51 faces the first portion 31 of the flange 30.

  When the rotational position of the lid 50 with respect to the main body 20 is set to the second position (see FIGS. 8 and 9), the convex space 51A, which is a space formed in the convex portion 51, and the housing 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 convex portion 51 faces the concave portion 32A formed in the second portion 32 of the flange 30.

An example of a method of filling the contents into the package 1 will be described.
As shown in FIG. 4, 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. One example of the liquid content 110 is a seasoning such as a sauce.

  As shown in FIG. 5 or FIG. 6, after the liquid content 110 is stored in the storage space 21 of the tray 10, the lid 50 is moved so that the rotation position of the lid 50 with respect to the main body 20 becomes the first position. The sealing process is performed on the portion to be sealed 40 and the portion of the lid 50 corresponding to the portion to be sealed 40. For this reason, a seal portion 60, which is a portion where the lid 50 and the tray 10 are sealed, is formed in the portion that was the portion to be sealed 40. The seal part 60 is also formed between the edge of the opening 11 and the convex part 51. For this reason, connection between the convex space 51 </ b> A of the lid 50 and the storage space 21 of the tray 10 is prevented by the seal portion 60. The package 1 in which the seal part 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. 7, 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. The lid 50 is once removed from the tray 10. For this reason, the seal part 60 peels off. After removing the lid 50 from the tray 10, the end user adds the solid content 120 to the liquid content 110. Examples of the solid content 120 are meat and vegetables.

  As shown in FIG. 8 or FIG. 9, the end user adds the solid content 120 to the liquid content 110 and then trays the lid 50 so that the rotation 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 the heating means. When the package 1 is heated, the liquid content 110 and the solid content 120 generate steam. When the rotational position of the lid 50 with respect to the main body 20 is set to the second position, the convex space 51 </ b> A and the storage space 21 are connected to each other, so that the water vapor generated from the liquid content 110 and the solid content 120 loses the convex 51. It is appropriately discharged to the outside through the portion that opens outside. After the heating of the package 1 is completed, the end user removes the package 1 from the heating means by grasping, for example, the first portion 31 of the flange 30.

According to the package 1, the following effects can be obtained.
(1) After accommodating the liquid content 110 in the accommodation space 21 of the tray 10, the sealing portion 40 and the lid 50 are sealed with the rotation position of the lid 50 with respect to the main body 20 set to the first position. A seal portion 60 is formed between the edge of the opening 11 of the tray 10 and the convex portion 51. Therefore, the connection between the convex space 51 </ b> A and the storage space 21 is prevented by the seal portion 60, and it is difficult for foreign matter to enter the storage space 21 of the tray 10 from a portion opened outside the convex portion 51.

  (2) When the rotational position of the lid 50 with respect to the main body 20 is set to the second position, the convex space 51A and the housing space 21 are connected, and the liquid content 110 and the solid Water vapor generated from the shape contents 120 is appropriately discharged to the outside through a portion that opens toward the outside of the convex portion 51.

  (3) When the position of the lid 50 with respect to the main body 20 is set to the second position, the convex portion 51 faces the concave portion 32A formed on the flange 30. Therefore, the concave portion 32A is formed at the portion facing the convex portion 51. There is a concave space 32B. For this reason, the water vapor that is going to be discharged from the accommodation space 21 to the outside through the concave space 32B, the convex space 51A, and the portion that opens outside the convex portion 51 does not easily stay near the convex portion 51. In addition, water vapor is more easily discharged.

  (4) When the package 1 in which the liquid content 110 and the solid content 120 are stored in the tray 10 is heated, the package 1 is opened from the storage space 21 of the tray 10 to the outside of the protrusion 51. Water vapor is discharged. For this reason, the temperature of the second portion 32 of the flange 30 where the concave portion 32A facing the convex portion 51 is formed is high. Since the package 1 has the flange 30 formed entirely around the opening 11 of the main body 20, the end user can use the portion of the flange 30 of the heated package 1 other than the portion where the recess 32 </ b> A is formed, that is, In addition, a relatively low temperature part can be gripped. Therefore, 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 grasp the first portion 31 of the flange 30 which is a relatively low temperature portion.

  (6) Since the pre-seal portion 40 is formed entirely around the opening 11, the liquid content 110 is accommodated in the accommodation space 21, and the rotation position of the lid 50 with respect to the main body 20 is set to the first position. The sealing portion 40 and the lid 50 are sealed in this state, so that the sealing portion 60 is formed entirely around the 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 storage space 21 of the tray 10.

A package 1 according to a fourth embodiment will be described with reference to FIGS. In addition, the same reference numerals as in the first embodiment denote the same components as those in the first embodiment, and a description thereof will be omitted.

  As shown in FIG. 17, the tray 410 of the package 1 includes a main body 420 forming a storage space 421 that is a space capable of storing the liquid content 110 and the solid content 120 (see FIG. 21), and the opening 411. It has a flange 430 formed around it. The layer structure of the tray 410 and the material constituting each layer are the same as those of the tray 10 of the first embodiment. Note that a two-dot chain line shown in FIG. 17 is a region formed on the flange 430 of the tray 410 and formed with a pre-seal portion 440 which is a portion to be sealed with the lid 450 (see FIG. 18).

  The flange 430 is formed entirely around the opening 411. The flange 430 has a rectangular flat portion 431 in plan view, a concave portion 432 formed in the flat portion 431, a pair of holes 433 facing each other via the main body 420 in the short direction of the main body 420, and A pair of holes 434 facing each other via the main body 420 in the lateral direction is provided. The concave space 432A, which is the space inside the concave portion 432, is connected to the housing space 421 of the main body 420.

The pre-seal portion 440 is formed around the opening of the concave portion 432 and around the opening 411 of the main body 420.
As shown in FIG. 18, the lid 450 of the package 1 has a rectangular shape in plan view, and includes a protrusion 451 and two protrusions 452 inserted into the holes 433 and 434 of the flange 430 (see FIG. 17). . The layer structure of the lid 450 and the material constituting each layer are the same as those of the lid 50 of the first embodiment.

The convex portion 451 is formed in a portion including the edge 450A of the lid 450, has a hollow shape protruding toward the front side of the lid 450, and opening toward the outside and the bottom side of the lid 450.
As shown in FIG. 19, the protrusion 452 has a columnar shape and extends downward in the height direction of the package 1.

  The lid 450 has a plurality of positions that can be attached to the tray 410. The positions include a first position and a second position. The end user changes the position of the lid 450 with respect to the main body 420 by shifting the lid 450 in the longitudinal direction of the main body 420.

  When the position of the lid 450 with respect to the main body 420 is set to the first position (see FIG. 20), the convex portion 451 is arranged in a portion of the flange 430 closer to the edge of the flange 430 than the seal portion 460. When the position of the lid 450 with respect to the main body 420 is set to the first position, the convex part 451 faces the flat part 431 of the flange 430, and the two projections 452 of the lid 450 fit into the two holes 433 of the flange 430. Inserted.

  On the other hand, when the position of the lid 450 with respect to the main body 420 is set to the second position (see FIG. 21), the convex space 451A, which is a space formed in the convex 451, and the housing space 421 are connected. When the position of the lid 450 with respect to the main body 420 is set to the second position, the convex portion 451 faces the concave portion 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. 20, after the liquid content 110 is stored in the storage space 421 of the tray 410, 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. The lid 450 is inserted into the tray 433, the lid 450 is attached to the tray 410, and the sealing portion 440 is sealed. Therefore, a seal portion 460, which is a portion where the lid 450 and the tray 410 are sealed, is formed in the portion that was the portion to be sealed 440. Since the seal portion 460 is also formed between the edge of the opening 411 and the convex portion 451, the connection between the convex space 451A of the lid 450 and the storage space 421 of the tray 410 is prevented by the seal portion 460.

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

  As shown in FIG. 21, after adding 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 so that the position of the lid 450 with respect to the main body 420 is the second position. Then, 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 the heating means. When the package 1 is heated, the liquid content 110 and the solid content 120 generate steam. When the position of the lid 450 with respect to the main body 420 is set to the second position, since the convex space 451A and the storage space 421 are connected, the water vapor generated from the liquid content 110 and the solid content 120 loses the convex portion 451. It is appropriately discharged to the outside through the portion that opens 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 removes the package 1 from the heating means. According to the package 1, effects according to the above (1) to (4), (6), and (7) can be obtained.
