Description

本発明は、加熱された物品を収容する包装袋に関する。 The present invention relates to a packaging bag that houses a heated article.

従来から、樹脂シートを用いて形成された包装袋が知られている。該包装袋は、物品を収容する収容空間を形成する袋本体を備える。該袋本体は、対向するように配置された一対の対向シート部を備えると共に、該一対の対向シート部の間に収容空間が形成される(特許文献1参照)。 Conventionally, a packaging bag formed by using a resin sheet has been known. The packaging bag includes a bag body that forms a storage space for storing articles. The bag body includes a pair of facing sheet portions arranged so as to face each other, and a storage space is formed between the pair of facing seat portions (see Patent Document 1).

ところで、上述のような包装袋に収容される物品は、包装袋に収容される前に加熱された状態であったり、包装袋に収容された状態で電子レンジや湯煎等によって加熱されたりする場合がある。例えば、包装袋に収容された物品が米飯加工食品(例えば、チャーハンやおにぎり等)である場合、米飯加工食品を食する際に、包装袋に収容された状態の米飯加工食品が電子レンジ等で加熱される場合がある。 By the way, when the article stored in the packaging bag as described above is in a heated state before being stored in the packaging bag, or is heated in a microwave oven, a water bath, or the like while being stored in the packaging bag. There is. For example, when the article contained in the packaging bag is processed rice food (for example, fried rice, rice balls, etc.), when eating the processed rice food, the processed rice food contained in the packaging bag is placed in a microwave oven or the like. May be heated.

しかしながら、包装袋に物品が収容されてなる包装体を手で把持する際に、物品が加熱された状態であると、物品の熱が包装袋を介して手に伝わり、包装体を手で把持することが困難になる虞がある。 However, when the article is held in the packaging bag by hand, if the article is in a heated state, the heat of the article is transferred to the hand through the packaging bag and the package is gripped by hand. It may be difficult to do.

そこで、本発明は、包装袋に物品が収容されてなる包装体を手で把持する際に、物品が加熱された状態であっても、包装体を手で容易に把持することができる包装袋を提供することを課題とする。 Therefore, according to the present invention, when the packaging body in which the article is stored in the packaging bag is gripped by hand, the packaging bag can be easily grasped by hand even when the article is heated. The challenge is to provide.

本発明に係る包装袋は、樹脂シートを用いて袋状に形成されると共に、加熱される物品を収容可能な収容空間を形成する袋本体を備えており、該袋本体は、対向するように配置された一対の対向シート部を備えると共に、該一対の対向シート部の間に収容空間が形成され、一方向における一対の対向シート部の一端部側で収容空間が閉塞されている包装袋であって、一対の対向シート部における収容空間を挟んで対向する領域を袋本体の外側から覆うシート状の被覆部材を更に備えており、該被覆部材は、紙および不織布の少なくとも一方を用いて形成されると共に、一方向における一対の対向シート部の一端部側に配置されており、一対の対向シート部は、被覆部材で覆われた被覆領域と、被覆部材で覆われていない非被覆領域とを備える。 The packaging bag according to the present invention is formed in the shape of a bag using a resin sheet, and is provided with a bag body that forms a storage space capable of accommodating an article to be heated, so that the bag bodies face each other. A packaging bag provided with a pair of facing sheet portions arranged, and a storage space is formed between the pair of facing seat portions, and the storage space is closed on one end side of the pair of facing seat portions in one direction. Further, a sheet-like covering member for covering the facing regions of the pair of facing sheet portions across the accommodation space from the outside of the bag body is further provided, and the covering member is formed by using at least one of paper and non-woven fabric. At the same time, they are arranged on one end side of a pair of facing sheet portions in one direction, and the pair of facing sheet portions include a covered region covered with a covering member and a non-covered region not covered with a covering member. To be equipped.

斯かる構成によれば、袋本体が備える一対の対向シート部における収容空間を挟んで対向する領域を袋本体の外側から覆うシート状の被覆部材を備える。また、被覆部材は、紙および不織布の少なくとも一方を用いて形成される。また、被覆部材は、一方向における一対の対向シート部の一端部側に配置される。そして、一対の対向シート部は、被覆部材で覆われた被覆領域と、被覆部材で覆われていない非被覆領域とを備える。また、被覆領域は、一方向における一対の対向シート部の一端部近傍に形成される。 According to such a configuration, a sheet-like covering member is provided which covers the facing regions of the pair of facing sheet portions included in the bag body from the outside of the bag body. Further, the covering member is formed by using at least one of paper and non-woven fabric. Further, the covering member is arranged on one end side of a pair of facing sheet portions in one direction. The pair of facing sheet portions includes a covered region covered with a covering member and a non-covered region not covered with the covering member. Further, the covering region is formed in the vicinity of one end portion of the pair of facing sheet portions in one direction.

これにより、物品が包装袋に収容されて包装体が形成された状態において、包装袋における被覆部材を備える箇所では、収容空間に収容された物品の熱が包装袋の外側に伝わり難くなる。このため、包装袋における被覆部材を備える箇所を手で把持することで、物品の熱の影響を受けずに包装体を手で容易に把持することができる。
また、非被覆領域から物品の熱が包装袋の外側に放散されるため、被覆部材で一対の対向シート部の全体が覆われている場合(非被覆領域を備えない場合)よりも物品を迅速に冷ますことができる。
As a result, in a state where the article is housed in the packaging bag and the packaging body is formed, the heat of the article housed in the storage space is less likely to be transferred to the outside of the packaging bag at the place where the covering member is provided in the packaging bag. Therefore, by grasping the portion of the packaging bag provided with the covering member by hand, the package can be easily grasped by hand without being affected by the heat of the article.
In addition, since the heat of the article is dissipated from the uncovered area to the outside of the packaging bag, the article can be swiftly processed as compared with the case where the entire pair of facing sheets are covered with the covering member (when the uncovered area is not provided). Can be cooled down.

袋本体は、前記一方向における一対の対向シート部の一端部同士を連結する連結シート部を備えており、非被覆領域は、前記一方向における被覆領域よりも一対の対向シート部の一端部側の領域であって該一端部を含む領域と、前記一方向における被覆領域よりも一対の対向シート部の他端部側の領域とに形成されることが好ましい。 The bag body includes a connecting sheet portion that connects one ends of the pair of facing sheet portions in one direction, and the uncovered area is one end side of the pair of facing sheet portions with respect to the covered area in the one direction. It is preferable that the region is formed in a region including one end portion and a region on the other end side of the pair of facing sheet portions with respect to the covering region in the one direction.

斯かる構成によれば、袋本体は、前記一方向における一対の対向シート部の一端部同士を連結する連結シート部を備える。また、非被覆領域は、前記一方向における被覆領域よりも一対の対向シート部の一端部側の領域であって該一端部を含む領域と、前記一方向における被覆領域よりも一対の対向シート部の他端側の領域とに形成される。 According to such a configuration, the bag body includes a connecting seat portion that connects one ends of the pair of opposed seat portions in one direction. Further, the uncovered region is a region on one end side of the pair of facing sheet portions with respect to the covering region in the one direction, and the region including the one end portion and the pair of facing sheet portions with respect to the covering region in the one direction. It is formed in the region on the other end side of.

ここで、物品が包装袋に収容されて包装体が形成された状態において、包装袋に収容された物品が粒状や粉状である場合、前記一方向における一対の対向シート部の一端部と連結シート部との連結位置の近傍に物品が溜まる場合がある。しかしながら、上記のように、前記一方向における一対の対向シート部の一端部を含む領域に非被覆領域(以下、一端側非被覆領域とも記す)が形成されることで、包装袋は、被覆部材を備える領域よりも一端側非被覆領域の方が変形し易くなる。これにより、前記一方向における一対の対向シート部の一端部と連結シート部との連結位置の近傍に物品が溜まるような場合であっても、一端側非被覆領域を変形させることで溜まった物品を容易に取り出すことができる。 Here, in a state where the article is housed in the packaging bag and the package is formed, when the article housed in the packaging bag is granular or powdery, it is connected to one end of the pair of facing sheet portions in the one direction. Articles may collect in the vicinity of the connection position with the seat portion. However, as described above, the packaging bag is formed of a covering member by forming an uncovered region (hereinafter, also referred to as an uncoated region on one end side) in a region including one end portion of the pair of facing sheet portions in one direction. The uncovered area on one end side is more easily deformed than the area provided with. As a result, even when articles are accumulated in the vicinity of the connecting position between one end of the pair of facing sheet portions in one direction and the connecting sheet portion, the accumulated articles are formed by deforming the uncovered area on one end side. Can be easily taken out.

被覆部材は、前記一方向に交差する他方向における一対の対向シート部の両端部間に亘って帯状に形成されることが好ましい。 The covering member is preferably formed in a band shape over both ends of the pair of opposed sheet portions in the other direction intersecting in the one direction.

斯かる構成によれば、被覆部材は、前記一方向に交差する他方向における一対の対向シート部の両端部間に亘って帯状に形成される。このため、物品が包装袋に収容されて包装体が形成された状態において、包装袋における被覆部材を備える領域をより容易に手で把持することができる。 According to such a configuration, the covering member is formed in a band shape over both end portions of the pair of opposing sheet portions in the other direction intersecting in the one direction. Therefore, in a state where the article is housed in the packaging bag and the packaging body is formed, the region of the packaging bag including the covering member can be more easily grasped by hand.

被覆部材は、袋本体と接合された被覆部材接合部と、袋本体と接合されていない被覆部材非接合部とを備えており、被覆部材非接合部は、被覆部材の端部よりも内側の領域から被覆部材の端部に達すように連続的に形成されることが好ましい。 The covering member includes a covering member joint portion joined to the bag body and a covering member non-joining portion not joined to the bag body, and the covering member non-joining portion is inside the end portion of the covering member. It is preferably formed continuously so as to reach the end of the covering member from the region.

斯かる構成によれば、被覆部材は、袋本体と接合された被覆部材接合部と、袋本体と接合されていない被覆部材非接合部とを備える。また、被覆部材非接合部は、被覆部材の端部よりも内側の領域から被覆部材の端部に達すように連続的に形成される。 According to such a configuration, the covering member includes a covering member joint portion joined to the bag body and a covering member non-joining portion not joined to the bag body. Further, the non-joint portion of the covering member is continuously formed so as to reach the end portion of the covering member from a region inside the end portion of the covering member.

このため、物品が包装袋に収容されて包装体が形成された状態において、被覆部材非接合部と袋本体との間の熱が被覆部材の端部と袋本体との間から排出されるため、包装袋における被覆部材を備える領域をより容易に手で把持することができる。 Therefore, in a state where the article is housed in the packaging bag and the package is formed, the heat between the non-joined portion of the covering member and the bag body is discharged from between the end portion of the covering member and the bag body. , The area of the packaging bag provided with the covering member can be more easily grasped by hand.

被覆部材は、袋本体と接合された被覆部材接合部と、袋本体と接合されていない被覆部材非接合部とを備えており、被覆部材非接合部は、前記一方向における被覆部材20の両端部と、被覆部材の端部よりも内側の領域とに形成されており、被覆部材の端部よりも内側の被覆部材非接合部と被覆部材の端部の被覆部材非接合部との間に被覆部材接合部が形成されることで、被覆部材の端部よりも内側の被覆部材非接合部が被覆部材の端部の被覆部材非接合部に達しないように構成されることが好ましい。 The covering member includes a covering member joint portion joined to the bag body and a covering member non-joining portion not joined to the bag body, and the covering member non-joining portion includes both ends of the covering member 20 in one direction. Between the non-joined portion of the covering member and the non-joined portion of the covering member at the end of the covering member, which are formed in the portion and the region inside the end of the covering member. It is preferable that the covering member joint portion is formed so that the covering member non-joining portion inside the covering member non-joining portion does not reach the covering member non-joining portion at the end portion of the covering member.

斯かる構成によれば、被覆部材は、袋本体と接合された被覆部材接合部と、袋本体と接合されていない被覆部材非接合部とを備える。また、被覆部材非接合部は、前記一方向における被覆部材20の両端部と、被覆部材の端部よりも内側の領域とに形成される。また、被覆部材の端部よりも内側の被覆部材非接合部と被覆部材の端部の被覆部材非接合部との間に被覆部材接合部が形成されることで、被覆部材の端部よりも内側の被覆部材非接合部が被覆部材の端部の被覆部材非接合部に達しないように構成される。 According to such a configuration, the covering member includes a covering member joint portion joined to the bag body and a covering member non-joining portion not joined to the bag body. Further, the non-joining portion of the covering member is formed at both ends of the covering member 20 in the one direction and a region inside the end portion of the covering member. Further, by forming a covering member joint between the non-joining portion of the covering member inside the end portion of the covering member and the non-joining portion of the covering member at the end portion of the covering member, the joint portion of the covering member is formed more than the end portion of the covering member. The inner non-joint portion of the covering member is configured so as not to reach the non-joint portion of the covering member at the end of the covering member.

これにより、物品が包装袋に収容されて包装体が形成された状態において、被覆部材の端部よりも内側の被覆部材非接合部と袋本体との間に空気の層が形成され易くなるため、物品の熱が包装袋の外側により伝わりに難くなる。このため、包装袋における被覆部材を備える領域をより容易に手で把持することができる。 As a result, when the article is housed in the packaging bag and the package is formed, an air layer is likely to be formed between the non-joined portion of the covering member and the bag body inside the end portion of the covering member. , The heat of the article is less likely to be transferred to the outside of the packaging bag. Therefore, the area of the packaging bag including the covering member can be more easily grasped by hand.

以上のように、本発明によれば、包装袋に物品が収容されてなる包装体を手で把持する際に、物品が加熱された状態であっても、包装体を手で容易に把持することができる。 As described above, according to the present invention, when the packaging body in which the article is stored in the packaging bag is gripped by hand, the packaging body is easily gripped by hand even when the article is in a heated state. be able to.

The heated article is housed in the packaging bag 100 configured as described above. The article contained in the packaging bag 100 is not particularly limited, and examples thereof include granular, powdery, and liquid articles. The articles contained in the packaging bag 100 may be, for example, processed rice rice foods (specifically, fried rice, rice balls, etc.), sandwiches, curry, and other foods, and may be non-food items. Good.
Further, the article housed in the packaging bag 100 may be heated before being stored in the packaging bag 100, or may be heated after being stored in the packaging bag 100. The method for heating the article is not particularly limited, and examples thereof include a microwave oven, an oven, and a water bath.

包装袋100は、物品が収容された状態で収容空間Rが閉塞される。収容空間Rを閉塞する方法としては、特に限定されるものではなく、例えば、筒状部10aの開口部10cを閉塞するようにシールすることで、収容空間Rを閉塞してもよい。又は、包装袋100に収容された物品と開口部10cとの間の位置で筒状部10a(具体的には、一対の対向シート部11,11)を捻りまわすことで、収容空間Rを閉塞してもよい。 In the packaging bag 100, the storage space R is closed in a state where the articles are stored. The method of closing the accommodation space R is not particularly limited, and for example, the accommodation space R may be closed by sealing the opening 10c of the tubular portion 10a so as to close it. Alternatively, the storage space R is closed by twisting the tubular portion 10a (specifically, the pair of facing sheet portions 11, 11) at the position between the article housed in the packaging bag 100 and the opening 10c. You may.

以上のように、本実施形態に係る包装袋100によれば、包装袋100に物品が収容されてなる包装体を手で把持する際に、物品が加熱された状態であっても、包装体を手で容易に把持することができる。 As described above, according to the packaging bag 100 according to the present embodiment, when the packaging body in which the article is housed in the packaging bag 100 is gripped by hand, the packaging body is heated even when the article is heated. Can be easily grasped by hand.

即ち、袋本体10が備える一対の対向シート部11,11における収容空間Rを挟んで対向する領域を袋本体10の外側から覆うシート状の被覆部材20を備える。また、被覆部材20は、紙および不織布の少なくとも一方を用いて形成される。また、被覆部材20は、一方向における一対の対向シート部11,11の一端部側に配置される。そして、一対の対向シート部11,11は、被覆部材20で覆われた被覆領域11bと、被覆部材20で覆われていない非被覆領域11cとを備える。また、被覆領域11bは、一方向における一対の対向シート部11,11の一端部近傍に形成される。 That is, the bag body 10 is provided with a sheet-like covering member 20 that covers the facing regions of the pair of facing sheet portions 11 and 11 with the accommodation space R sandwiched from the outside of the bag body 10. Further, the covering member 20 is formed by using at least one of paper and non-woven fabric. Further, the covering member 20 is arranged on one end side of the pair of facing sheet portions 11 and 11 in one direction. The pair of facing sheet portions 11 and 11 include a covered region 11b covered with the covering member 20 and an uncovered region 11c not covered with the covering member 20. Further, the covering region 11b is formed in the vicinity of one end portion of the pair of facing sheet portions 11 and 11 in one direction.

これにより、物品が包装袋100に収容されて包装体(図示せず)が形成された状態において、包装袋100における被覆部材20を備える箇所では、収容空間Rに収容された物品の熱が包装袋100の外側に伝わり難くなる。このため、包装袋100における被覆部材20を備える箇所を手で把持することで、物品の熱の影響を受けずに包装体を容易に把持することができる。また、非被覆領域11cから物品の熱が包装袋100の外側に放散されるため、被覆部材20で一対の対向シート部11,11の全体が覆われている場合(非被覆領域11cを備えない場合)よりも物品を迅速に冷ますことができる。 As a result, in a state where the article is housed in the packaging bag 100 and a package (not shown) is formed, the heat of the article housed in the storage space R is packaged at the place where the covering member 20 is provided in the package bag 100. It becomes difficult to reach the outside of the bag 100. Therefore, by manually grasping the portion of the packaging bag 100 provided with the covering member 20, the package can be easily grasped without being affected by the heat of the article. Further, since the heat of the article is dissipated from the uncovered region 11c to the outside of the packaging bag 100, the case where the entire pair of facing sheet portions 11 and 11 is covered by the covering member 20 (the uncoated region 11c is not provided). If) the goods can be cooled more quickly.

また、袋本体10は、前記一方向における一対の対向シート部11,11の一端部同士を連結する連結シート部12を備える。また、非被覆領域11cは、前記一方向における被覆領域11bよりも一対の対向シート部11,11の一端部側の領域であって該一端部を含む領域と、前記一方向における被覆領域11bよりも一対の対向シート部11,11の他端側の領域とに形成される。 Further, the bag body 10 includes a connecting sheet portion 12 that connects one ends of the pair of opposed seat portions 11 and 11 in one direction. Further, the non-covered region 11c is a region on the one end side of the pair of facing sheet portions 11 and 11 with respect to the covered region 11b in the one direction, and includes the one end portion and the covered region 11b in the one direction. Is also formed in a region on the other end side of the pair of facing sheet portions 11, 11.

ここで、物品が包装袋100に収容されて包装体(図示せず)が形成された状態において、包装袋100に収容された物品が粒状や粉状である場合、前記一方向における一対の対向シート部11,11の一端部と連結シート部12との連結位置の近傍に物品が溜まる場合がある。しかしながら、上記のように、前記一方向における一対の対向シート部11,11の一端部を含む領域に非被覆領域11c(以下、一端側非被覆領域11dとも記す)が形成されることで、包装袋100は、被覆部材20を備える領域よりも一端側非被覆領域11dの方が変形し易くなる。これにより、前記一方向における一対の対向シート部11,11の一端部と連結シート部12との連結位置の近傍に物品が溜まるような場合であっても、一端側非被覆領域11dを変形させることで溜まった物品を容易に取り出すことができる。 Here, in a state where the articles are housed in the packaging bag 100 and a package (not shown) is formed, when the articles housed in the packaging bag 100 are granular or powdery, the pair of opposed surfaces in the one direction. Articles may collect in the vicinity of the connecting position between one end of the sheet portions 11 and 11 and the connecting sheet portion 12. However, as described above, the uncovered region 11c (hereinafter, also referred to as one end side uncovered region 11d) is formed in the region including one end portion of the pair of facing sheet portions 11 and 11 in one direction, so that the packaging is packaged. The bag 100 is more easily deformed in the one-sided uncovered region 11d than in the region including the covering member 20. As a result, even in the case where articles are accumulated in the vicinity of the connecting position between one end of the pair of facing sheet portions 11 and 11 in one direction and the connecting sheet portion 12, the uncovered region 11d on the one end side is deformed. As a result, the accumulated articles can be easily taken out.

また、被覆部材20は、前記一方向に交差する他方向における一対の対向シート部11,11の両端部間に亘って帯状に形成される。このため、物品が包装袋100に収容されて包装体(図示せず)が形成された状態において、包装袋100における被覆部材20を備える領域をより容易に手で把持することができる。 Further, the covering member 20 is formed in a band shape over both end portions of the pair of opposed sheet portions 11 and 11 in the other direction intersecting in the one direction. Therefore, in a state where the article is housed in the packaging bag 100 and the packaging body (not shown) is formed, the region of the packaging bag 100 including the covering member 20 can be more easily grasped by hand.

また、被覆部材20は、袋本体10と接合された被覆部材接合部20aと、袋本体10と接合されていない被覆部材非接合部20bとを備える。また、被覆部材非接合部20bは、被覆部材20の端部よりも内側の領域から被覆部材20の端部に達すように連続的に形成される。 Further, the covering member 20 includes a covering member joining portion 20a joined to the bag main body 10 and a covering member non-joining portion 20b not joined to the bag main body 10. Further, the non-joining portion 20b of the covering member is continuously formed so as to reach the end portion of the covering member 20 from a region inside the end portion of the covering member 20.

このため、物品が包装袋100に収容されて包装体(図示せず)が形成された状態において、被覆部材非接合部20bと袋本体10との間の熱が被覆部材20の端部と袋本体10との間から排出されるため、包装袋100における被覆部材20を備える領域をより容易に手で把持することができる。 Therefore, in a state where the article is housed in the packaging bag 100 and the package (not shown) is formed, the heat between the non-joining portion 20b of the covering member and the bag body 10 is generated between the end portion of the covering member 20 and the bag. Since it is discharged from between the main body 10 and the main body 10, the region of the packaging bag 100 including the covering member 20 can be more easily grasped by hand.

なお、本発明に係る包装袋は、上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の変更が可能である。また、上記した複数の実施形態の構成や方法等を任意に採用して組み合わせてもよく(1つの実施形態に係る構成や方法等を他の実施形態に係る構成や方法等に適用してもよく)、さらに、下記の各種の変更例に係る構成や方法等を任意に選択して、上記の実施形態に係る構成や方法等に採用してもよいことは勿論である。 The packaging bag according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention. Further, the configurations and methods of the plurality of embodiments described above may be arbitrarily adopted and combined (the configurations and methods of one embodiment may be applied to the configurations and methods of other embodiments). Of course, the configurations and methods according to the following various modification examples may be arbitrarily selected and adopted for the configurations and methods according to the above-described embodiment.

例えば、上記実施形態では、被覆部材非接合部20bは、被覆部材20の端部よりも内側の領域から被覆部材20の端部に達すように連続的に形成されるが、これに限定されるものではない。
例えば、図4に示すように、被覆部材20の端部よりも内側に形成された被覆部材非接合部20bと被覆部材20の端部に形成された被覆部材非接合部20bとの間に被覆部材接合部20aが形成されることで、被覆部材20の端部よりも内側の被覆部材非接合部20bが被覆部材20の端部の被覆部材非接合部20bに達しないように構成されてもよい。具体的には、前記他方向における一対の対向シート部11,11(具体的には、筒状部10a)の両端間の全域に亘って被覆部材接合部20aが帯状に形成されると共に、該被覆部材接合部20aが前記一方向に間隔を空けて複数形成される。そして、前記一方向における被覆部材20の両端部と、隣り合う被覆部材接合部20aの間の領域(即ち、被覆部材20の端部よりも内側の領域)とに被覆部材非接合部20bが形成される。これにより、前記一方向における被覆部材20の両端部に形成された被覆部材非接合部20bと、隣り合う被覆部材接合部20aの間(即ち、被覆部材20の端部よりも内側)に形成された被覆部材非接合部20bとの間に、被覆部材接合部20aが位置することになる。このため、被覆部材20の端部よりも内側の被覆部材非接合部20bは、被覆部材接合部20aによって被覆部材20の端部の被覆部材非接合部20bに達しないように構成される。
For example, in the above embodiment, the covering member non-joining portion 20b is continuously formed so as to reach the end portion of the covering member 20 from a region inside the end portion of the covering member 20, but is limited to this. It's not a thing.
