Description
本発明は、物品と保冷材とを収容する保冷容器に関する。 The present invention relates to a cold insulation container that houses an article and a cold insulation material.
物品を容器に収容した状態で保管したり搬送したりする際には、物品の品質等の状態を維持するべく、物品と共に保冷材が容器に収容される場合がある。斯かる容器としては、例えば、筒状に形成された本体側壁部と該本体側壁部の一端部を閉塞する本体底部と本体側壁部の他端部に形成された本体開口部とを備える容器本体部と、本体開口部に対して着脱可能に取り付けられる蓋体部とを備えるものが知られている。そして、本体開口部に蓋体部が取り付けられた状態で、物品と板状の保冷材とを収容可能な収容空間が形成される。 When storing or transporting an article in a state of being accommodated in a container, a cold insulating material may be accommodated in the container together with the article in order to maintain a state such as the quality of the article. As such a container, for example, a container body provided with a main body side wall portion formed in a cylindrical shape, a main body bottom portion closing one end portion of the main body side wall portion, and a main body opening portion formed at the other end portion of the main body side wall portion. And a lid body part that is detachably attached to the opening of the main body are known. And the accommodation space which can accommodate articles | goods and a plate-shaped cold insulating material in the state by which the cover body part was attached to the main-body opening part is formed.
また、このような容器は、本体開口部を形成する本体側壁部の端部と蓋体部とが嵌合するように構成される場合がある。例えば、本体側壁部の端部と蓋体部とが凹凸嵌合するように構成されたり（特許文献１参照）、蓋体部の一部が本体開口部の内側から本体側壁部に摺接する（所謂、内嵌合する）ように構成されたりする場合がある。これにより、容器本体部に蓋体部を取り付けた状態が良好に維持されるため、収容空間における保冷材による保冷効果を良好に維持することが可能になる。 Moreover, such a container may be comprised so that the edge part of the main body side wall part which forms a main body opening part, and a cover body part may fit. For example, the end portion of the main body side wall portion and the lid body portion are configured to be unevenly fitted (see Patent Document 1), or a part of the lid body portion is in sliding contact with the main body side wall portion from the inside of the main body opening ( In some cases, it is configured to be so-called in-fitting. Thereby, since the state which attached the cover part to the container main-body part is maintained favorably, it becomes possible to maintain the cool effect by the cool insulating material in accommodation space favorably.
ところで、上記のような容器は、発泡樹脂を用いて形成される場合がある。具体的には、複数の発泡樹脂粒子を金型に充填し、蒸気過熱等することで一体的に成形することで、上記のような容器を形成することができる。このような発泡樹脂を用いて容器を形成することで、断熱性が比較的高くなるため、外気温の影響で収容空間の温度が上昇するのを抑制することができる。 By the way, the above containers may be formed using a foamed resin. Specifically, the container as described above can be formed by filling a plurality of foamed resin particles into a mold and integrally forming the mold by steam heating or the like. By forming the container using such a foamed resin, the heat insulating property becomes relatively high, so that the increase in the temperature of the accommodation space due to the influence of the outside air temperature can be suppressed.
しかしながら、上記のような容器は、継続的に使用されると、容器本体部と蓋体部との嵌合部分が摩耗し、容器本体部から蓋体部が意図せずに外れてしまう虞がある。また、容器本体部と蓋体部との嵌合部分が摩耗すると、容器本体部と蓋体部との間に隙間が生じ、該隙間を介して、容器の外側から内側へ熱が伝達される虞がある。このため、収容空間における保冷材による保冷効果を良好に維持することができなくなる虞がある。 However, when the container as described above is continuously used, the fitting portion between the container main body and the lid body wears down, and the lid may be unintentionally detached from the container main body. is there. In addition, when the fitting portion between the container main body and the lid body is worn, a gap is generated between the container main body and the lid body, and heat is transferred from the outside to the inside of the container through the gap. There is a fear. For this reason, there exists a possibility that the cold insulation effect by the cold insulation material in an accommodation space cannot be maintained favorable.
そこで、本発明は、物品と共に保冷材が収容される保冷容器において、収容空間における保冷材による保冷効果を良好に維持することができる保冷容器を提供することを課題とする。 Then, this invention makes it a subject to provide the cold insulation container which can maintain the cold insulation effect by the cold insulation material in accommodation space favorably in the cold insulation container in which a cold insulation material is accommodated with an article | item.
本発明に係る保冷容器は、筒状に形成された本体側壁部と該本体側壁部の一端部を閉塞する本体底部と本体側壁部の他端部に形成された本体開口部とを備える容器本体部と、本体開口部から本体底部へ向かう一方向に沿って本体開口部に取り付けられる蓋体部とを備えており、
本体開口部に蓋体部が取り付けられて収容空間が形成される保冷容器であって、
蓋体部は、収容空間に配置された板状の保冷材と当接する保冷材当接部を備えており、
本体開口部に蓋体部が取り付けられた状態で、保冷材当接部に板状の保冷材が当接した状態が保持されるように構成される。
A cold storage container according to the present invention includes a main body side wall formed in a cylindrical shape, a main body bottom that closes one end of the main body side wall, and a main body opening formed at the other end of the main body side wall. And a lid portion attached to the main body opening along one direction from the main body opening to the bottom of the main body,
A cold storage container in which a lid portion is attached to a main body opening to form an accommodation space,
The lid portion includes a cold insulation material abutting portion that abuts a plate-like cold insulation material disposed in the accommodation space,
The state in which the plate-like cold insulation material is in contact with the cold insulation material abutting portion is held in a state where the lid portion is attached to the main body opening.
斯かる構成によれば、収容空間に収容された板状の保冷材は、蓋体部が備える保冷材当接部に当接した状態が保持される。これにより、保冷材当接部と板状の保冷材とが当接することによって生じる摩擦によって、容器本体部に対する蓋体部の良好な取り付け状態を維持することができる。このため、容器本体部から蓋体部が意図せずに外れてしまったり、本体開口部を形成する本体側壁部の端部から蓋体部が浮き上がって容器本体部と蓋体部との間に隙間が生じたりするのを抑制することができる。これにより、収容空間における板状の保冷材による保冷効果を良好に維持することができる。 According to such a configuration, the plate-shaped cold insulation material accommodated in the accommodation space is kept in contact with the cold insulation material contact portion provided in the lid portion. Thereby, the favorable attachment state of the cover part with respect to a container main-body part can be maintained by the friction which arises when a cold-insulating material contact part and a plate-shaped cold insulating material contact | abut. For this reason, the lid body part is unintentionally removed from the container body part, or the lid body part is lifted from the end of the body side wall part that forms the body opening, and between the container body part and the lid body part. It can suppress that a clearance gap arises. Thereby, the cold insulation effect by the plate-shaped cold insulation material in an accommodation space can be maintained favorable.
容器本体は、本体開口部に蓋体部が取り付けられた際に、前記一方向に対して交差する他方向から保冷材当接部に板状の保冷材が当接した状態を保持すると共に板状の保冷材が前記一方向に沿って配置された状態を保持する保冷材保持部を備えることが好ましい。 The container body holds the state in which the plate-like cold insulation material comes into contact with the cold insulation material contact portion from the other direction intersecting the one direction when the lid body portion is attached to the body opening. It is preferable to provide a cold insulating material holding part for holding a state in which the shape cold insulating material is arranged along the one direction.
斯かる構成によれば、収容空間に収容された板状の保冷材は、容器本体部が備える保冷材保持部によって、蓋体部が備える保冷材当接部に前記他方向から当接した状態が保持される。これにより、保冷材当接部と板状の保冷材とが当接することによって生じる摩擦（前記一方向に生じる摩擦）によって、容器本体部に対する蓋体部の良好な取り付け状態を維持することができる。このため、容器本体部から蓋体部が意図せずに外れてしまったり、本体開口部を形成する本体側壁部の端部から蓋体部が浮き上がって容器本体部と蓋体部との間に隙間が生じたりするのを抑制することができる。これにより、収容空間における板状の保冷材による保冷効果を良好に維持することができる。 According to such a configuration, the plate-shaped cold insulation material accommodated in the accommodation space is in contact with the cold insulation material abutting portion provided in the lid body portion from the other direction by the cold insulation material holding portion provided in the container main body portion. Is retained. Thereby, the favorable attachment state of the cover part with respect to a container main-body part can be maintained by the friction (friction which arises in the said one direction) which arises when a cold insulation material contact part and a plate-shaped cold insulation material contact | abut. . For this reason, the lid body part is unintentionally removed from the container body part, or the lid body part is lifted from the end of the body side wall part that forms the body opening, and between the container body part and the lid body part. It can suppress that a clearance gap arises. Thereby, the cold insulation effect by the plate-shaped cold insulation material in an accommodation space can be maintained favorable.
保冷材当接部は、本体開口部に蓋体部が取り付けられた状態で、本体側壁部と板状の保冷材との間に配置され、且つ、本体側壁部及び板状の保冷材と当接するように構成されることが好ましい。 The cold insulation material abutting portion is disposed between the main body side wall portion and the plate-shaped cold insulation material in a state where the lid portion is attached to the main body opening, and is contacted with the main body side wall portion and the plate-shaped cold insulation material. It is preferable to be configured to contact.
斯かる構成によれば、保冷材当接部は、本体開口部に蓋体部が取り付けられた状態で、本体側壁部と板状の保冷材との間に配置されて本体側壁部及び板状の保冷材と当接するように構成される。これにより、保冷材当接部と板状の保冷材との当接による摩擦だけでなく、本体側壁部と板状の保冷材との当接による摩擦も生じることになる。このため、容器本体部に対する蓋体部の良好な取り付け状態をより確実に維持することができる。これにより、収容空間における板状の保冷材による保冷効果をより良好に維持することができる。 According to such a configuration, the cold insulation material abutting portion is disposed between the main body side wall portion and the plate-like cold insulation material in a state where the lid portion is attached to the main body opening, and the main body side wall portion and the plate-like shape are arranged. It is comprised so that it may contact | abut with the cold insulating material. As a result, not only friction due to contact between the cold insulation material contact portion and the plate-like cold insulation material but also friction due to contact between the main body side wall portion and the plate-like cold insulation material occurs. For this reason, the favorable attachment state of the cover part with respect to a container main-body part can be maintained more reliably. Thereby, the cold insulation effect by the plate-shaped cold insulation material in an accommodation space can be maintained more favorably.
保冷材保持部は、本体側壁部から離間した位置に前記一方向に沿って配置される保冷材保持壁を備え、該保冷材保持壁と本体側壁部との間に板状の保冷材を配置可能に構成されており、本体開口部に蓋体部が取り付けられて本体側壁部と板状の保冷材との間に保冷材当接部が配置された際に、保冷材保持壁によって板状の保冷材が本体側壁部側へ押圧されるように構成されることが好ましい。 The cold insulation material holding portion includes a cold insulation material holding wall disposed along the one direction at a position separated from the main body side wall portion, and a plate-like cold insulation material is arranged between the cold insulation material holding wall and the main body side wall portion. It is configured so that when the lid is attached to the opening of the main body and the cold insulation material abutting portion is disposed between the main body side wall and the plate-like cold insulation material, a plate shape is formed by the cold insulation material holding wall. It is preferable that the cold insulating material is configured to be pressed toward the side wall of the main body.
斯かる構成によれば、本体開口部に蓋体部が取り付けられて本体側壁部と板状の保冷材との間に保冷材当接部が配置された際に、保冷材保持壁によって板状の保冷材が本体側壁部側へ押圧されるように構成される。これにより、保冷材当接部が本体側壁部と板状の保冷材とに挟み込まれることになるため、本体側壁部及び板状の保冷材と保冷材当接部との間に生じる摩擦がより大きくなる。これにより、容器本体部に対する蓋体部の良好な取り付け状態を更に確実に維持することができる。これにより、収容空間における板状の保冷材による保冷効果を更に良好に維持することができる。 According to such a configuration, when the lid portion is attached to the main body opening and the cold insulation material abutting portion is disposed between the main body side wall portion and the plate-like cold insulation material, the cold insulation material retaining wall forms a plate shape. The cold insulating material is configured to be pressed toward the side wall of the main body. As a result, the cold insulation material abutting portion is sandwiched between the main body side wall portion and the plate-like cold insulation material, so that the friction generated between the main body side wall portion and the plate-like cold insulation material and the cold insulation material contact portion is further increased. growing. Thereby, the favorable attachment state of the cover part with respect to a container main-body part can be maintained further reliably. Thereby, the cold insulation effect by the plate-shaped cold insulation material in an accommodation space can be maintained further favorably.
板状の保冷材が保冷材保持部に保持された状態で、板状の保冷材における本体底部側の端部から本体開口部側の端部へ向かって該端部間の長さの１／２以上２／３以下の領域が保冷材保持壁と重なるように構成されることが好ましい。 In a state where the plate-shaped cold insulation material is held by the cold insulation material holding portion, 1 / of the length between the end portions of the plate-like cold insulation material from the end portion on the bottom side of the main body toward the end portion on the opening side of the main body. It is preferable that the region of 2 or more and 2/3 or less overlap with the cold insulation material holding wall.
斯かる構成によれば、板状の保冷材が保冷材保持部に保持された状態で、板状の保冷材における本体底部側の端部から本体開口部側の端部へ向かって該端部間の長さの１／２以上２／３以下の領域が保冷材保持壁と重なるように構成される。ここで、収容空間における本体開口部の近傍の領域は、本体開口部を形成する本体側壁部の端部と蓋体部と接続部分に重なるため、外気温度の影響を受けやすい。しかしながら、上記のように構成されることで、板状の保冷材における保冷材保持壁と重ならない領域が本体開口部側に形成されるため、収容空間における本体開口部の近傍の領域を板状の保冷材によって冷却することができる。これにより、収容空間における板状の保冷材による保冷効果を良好に維持することができる。 According to such a configuration, in a state where the plate-shaped cold insulating material is held by the cold-insulating material holding portion, the end portion of the plate-shaped cold insulating material from the end portion on the main body bottom side toward the end portion on the main body opening side. The region between ½ and 2/3 of the length in between is configured to overlap the cold insulation material holding wall. Here, the region near the main body opening in the accommodation space overlaps with the end of the main body side wall forming the main body opening, the lid portion, and the connection portion, and thus is easily affected by the outside air temperature. However, since the region that does not overlap the cold insulation material holding wall in the plate-shaped cold insulation material is formed on the main body opening side by being configured as described above, the region in the vicinity of the main body opening in the accommodation space is plate-shaped. It can be cooled by a cold insulator. Thereby, the cold insulation effect by the plate-shaped cold insulation material in an accommodation space can be maintained favorable.
保冷材保持部は、保冷材保持壁と、該保冷材保持壁を取り付ける保持壁取付部とを備えており、該保持壁取付部に対して保冷材保持壁が着脱可能に構成されることが好ましい。 The cold insulation material holding portion includes a cold insulation material holding wall and a holding wall attachment portion to which the cold insulation material holding wall is attached, and the cold insulation material holding wall is configured to be detachable from the holding wall attachment portion. preferable.
斯かる構成によれば、保冷材保持部は、保冷材保持壁と、該保冷材保持壁を取り付ける保持壁取付部とを備えており、該保持壁取付部に対して保冷材保持壁が着脱自在に構成される。このため、保冷材保持壁が破損したり変形したりして板状の保冷材を本体側壁部側へ押圧できなくなっても、保冷材保持壁を交換することができる。また、保冷材保持壁を交換することで、板状の保冷材を本体側壁部側へ押圧する力を調節することができる。これにより、本体側壁部及び板状の保冷材と保冷材当接部との間に生じる摩擦を調節することができるため、容器本体部に対する蓋体部の着脱し易さを調節することができる。 According to such a configuration, the cold insulation material holding portion includes the cold insulation material holding wall and the holding wall mounting portion to which the cold insulation material holding wall is attached, and the cold insulation material holding wall is attached to and detached from the holding wall attachment portion. Freely configured. For this reason, even if the cold insulation material holding wall is damaged or deformed and the plate-like cold insulation material cannot be pressed toward the side wall of the main body, the cold insulation material holding wall can be exchanged. Moreover, the force which presses a plate-shaped cold insulating material to a main body side wall part side can be adjusted by replacing | exchanging a cold insulating material holding wall. Thereby, since the friction which arises between a main body side wall part and a plate-shaped cold insulating material and a cold insulating material contact part can be adjusted, the ease of attachment or detachment of the cover body part with respect to a container main body part can be adjusted. .
蓋体部には、本体開口部に蓋体部が取り付けられた際に、本体底部側へ開放する蓋体凹部が形成されており、保冷材保持部は、本体開口部に蓋体部が取り付けられた状態で、板状の保冷材における蓋体部側の端部が本体開口部よりも蓋体部側に位置し、且つ、該端部が蓋体凹部の内側に位置するように板状の保冷材を保持することが好ましい。 The lid is formed with a lid recess that opens to the bottom of the main body when the lid is attached to the main body opening. The cold insulator holder is attached to the main body opening. In such a state, the end of the plate-shaped cold insulating material on the lid body side is positioned on the lid body side of the main body opening, and the end is positioned on the inside of the lid recess. It is preferable to hold the cold insulating material.
斯かる構成によれば、保冷材保持部は、板状の保冷材における蓋体部側の端部が本体開口部よりも蓋体部側に位置し、且つ、該端部が蓋体凹部の内側に位置するように板状の保冷材を保持する。ここで、収容空間における本体開口部の近傍の領域と蓋体凹部の内側の領域は、外気温度の影響を受けやすい。しかしながら、上記のように構成されることで、本体開口部と重なる位置、及び、蓋体凹部の内側に板状の保冷材の一部が位置する。このため、収容空間における本体開口部の近傍の領域と蓋体凹部の内側の領域とを板状の保冷材によって冷却することができる。これにより、収容空間における板状の保冷材による保冷効果を良好に維持することができる。 According to such a configuration, the cold insulator holding portion is such that the end on the lid body side of the plate-shaped cold insulator is located closer to the lid body than the main body opening, and the end is the lid recess. A plate-shaped cold insulating material is held so as to be located inside. Here, the area near the main body opening in the housing space and the area inside the lid recess are easily affected by the outside air temperature. However, by being configured as described above, a part of the plate-shaped cold insulating material is positioned inside the lid concave portion at a position overlapping the main body opening. For this reason, the area | region near the main-body opening part in an accommodation space and the area | region inside a cover recessed part can be cooled with a plate-shaped cold insulating material. Thereby, the cold insulation effect by the plate-shaped cold insulation material in an accommodation space can be maintained favorable.

上記のように構成される保冷容器１０は、図３，４に示すように、容器本体部１に蓋体部２が取り付けられることで、物品と板状の保冷材Ｘとが収容される収容空間Ｒが形成される。この際、容器本体部１が備える嵌合凸部１ｇと蓋体部２が備える嵌合凹部２ｇとが凹凸嵌合すると共に、蓋体内側配置部２ｄ（本実施形態では、保冷材当接部２ｆ）が本体側壁部１ａの他端部（即ち、本体開口部１ｃ）と内嵌合するように構成される。 As shown in FIGS. 3 and 4, the cold insulation container 10 configured as described above is accommodated in which the article body and the plate-shaped cold insulation material X are accommodated by attaching the lid body part 2 to the container main body part 1. A space R is formed. At this time, the fitting convex portion 1g included in the container main body 1 and the fitting concave portion 2g included in the lid body portion 2 are unevenly fitted, and the lid inner side arrangement portion 2d (in this embodiment, the cold insulation material abutting portion). 2f) is configured to fit inside the other end of the main body side wall 1a (that is, the main body opening 1c).
そして、蓋体内側配置部２ｄ（本実施形態では、保冷材当接部２ｆ）は、保冷材保持部１ｄに保持された板状の保冷材Ｘと本体側壁部１ａとの間に配置される。この際、蓋体内側配置部２ｄ（本実施形態では、保冷材当接部２ｆ）は、前記一方向に対して交差する他方向から本体側壁部１ａ及び板状の保冷材Ｘと当接した状態になる。そして、保冷材保持部１ｄによって板状の保冷材Ｘが保冷材当接部２ｆ（具体的には、保冷材当接面２ｅ）に当接した状態が維持される。具体的には、蓋体内側配置部２ｄ（本実施形態では、保冷材当接部２ｆ）が板状の保冷材Ｘと本体側壁部１ａとの間に配置されることで、板状の保冷材Ｘが保冷材保持壁１ｅを押圧した状態になる。この際、その押圧に対向する応力（具体的には、押圧されて湾曲した保冷材保持壁１ｅが復元する方向の力）によって板状の保冷材Ｘが本体側壁部１ａ側へ押圧された状態になる。これにより、板状の保冷材Ｘが保冷材当接部２ｆ（具体的には、保冷材当接面２ｅ）に当接した状態が維持される。 The lid inner arrangement portion 2d (in this embodiment, the cold insulation material contact portion 2f) is arranged between the plate-like cold insulation material X held by the cold insulation material holding portion 1d and the main body side wall portion 1a. . At this time, the lid inner arrangement portion 2d (in this embodiment, the cold insulation material contact portion 2f) comes into contact with the main body side wall portion 1a and the plate-shaped cold insulation material X from the other direction intersecting the one direction. It becomes a state.

Specifically, the lid inner arrangement portion 2d (in this embodiment, the cold insulation material contact portion 2f) is arranged between the plate-like cold insulation material X and the main body side wall 1a, so that the plate-like cold insulation is provided. The material X is in a state of pressing the cold insulation material holding wall 1e. At this time, the plate-shaped cold insulating material X is pressed toward the main body side wall 1a by the stress opposite to the pressing (specifically, the force in the direction in which the pressed and curved cold insulating material holding wall 1e is restored). become. As a result, the state in which the plate-shaped cold insulation material X is in contact with the cold insulation material contact portion 2f (specifically, the cold insulation material contact surface 2e) is maintained.
また、本体側壁部１ａと板状の保冷材Ｘとの間には、隙間Ｇが形成される。該隙間Ｇが形成されることで、容器本体部１と蓋体部２との間を通って収容空間Ｒに伝わる熱の伝達が一次的に緩衝される。これにより、収容空間Ｒの温度変化を抑制することができる。また、板状の保冷材Ｘにおける蓋体部２側の端部が蓋体凹部２ｃの内側に配置される。つまり、保冷材保持部１ｄ（具体的には、保冷材載置部１ｆ）は、板状の保冷材Ｘにおける蓋体部２側の端部が本体開口部１ｃよりも蓋体部２側に位置するように板状の保冷材Ｘを保持する。 Further, a gap G is formed between the main body side wall 1a and the plate-shaped cold insulating material X. By forming the gap G, the transmission of heat transmitted to the accommodation space R through the space between the container body 1 and the lid body 2 is temporarily buffered. Thereby, the temperature change of the accommodation space R can be suppressed. Moreover, the edge part by the side of the cover body part 2 in the plate-shaped cold insulating material X is arrange | positioned inside the cover body recessed part 2c. In other words, the cold insulation material holding portion 1d (specifically, the cold insulation material placement portion 1f) is such that the end of the plate-like cold insulation material X on the lid body portion 2 side is closer to the lid body portion 2 side than the main body opening 1c. The plate-shaped cold insulating material X is held so as to be positioned.
なお、上記のように構成される保冷容器１０は、発泡樹脂を用いて形成されることが好ましい。発泡樹脂としては、特に限定されるものではなく、例えば、ポリスチレン系樹脂発泡体、ポリエチレン系樹脂発泡体、ポリプロピレン系樹脂発泡体、又は、ポリウレタン系樹脂発泡体等を用いることができる。また、これらの発泡樹脂の粒子が成形金型を用いて一体的に成形されて保冷容器１０が形成されてもよい。 In addition, it is preferable that the cold insulation container 10 comprised as mentioned above is formed using a foamed resin.

以上のように、本発明に係る保冷容器は、物品と共に保冷材が収容される保冷容器において、収容空間における保冷材による保冷効果を良好に維持することができる。 As described above, the cold insulation container according to the present invention can maintain a good cold insulation effect by the cold insulation material in the accommodation space in the cold insulation container in which the cold insulation material is accommodated together with the articles.
即ち、収容空間Ｒに収容された板状の保冷材Ｘは、容器本体部１が備える保冷材保持部１ｄによって、蓋体部２が備える保冷材当接部２ｆ（具体的には、保冷材当接面２ｅ）に当接した状態が維持される。これにより、保冷材当接部２ｆ（具体的には、保冷材当接面２ｅ）と板状の保冷材Ｘとが当接することによって生じる摩擦（前記一方向に生じる摩擦）によって、容器本体部１に対する蓋体部２の良好な取り付け状態を維持することができる。このため、容器本体部１から蓋体部２が意図せずに外れてしまったり、本体開口部１ｃを形成する本体側壁部１ａの端部から蓋体部２が浮き上がって容器本体部１と蓋体部２との間に隙間が生じたりするのを抑制することができる。これにより、収容空間Ｒにおける板状の保冷材Ｘによる保冷効果を良好に維持することができる。 That is, the plate-shaped cold insulation material X accommodated in the accommodation space R is cooled by the cold insulation material holding portion 1d provided in the container main body 1 and the cold insulation material abutting portion 2f provided in the lid portion 2 (specifically, the cold insulation material). The state of contact with the contact surface 2e) is maintained. Accordingly, the container main body portion is caused by friction (friction generated in the one direction) generated by contact between the cold insulation material contact portion 2f (specifically, the cold insulation material contact surface 2e) and the plate-shaped cold insulation material X. 1 can maintain a favorable attachment state of the lid portion 2 to 1. For this reason, the lid body part 2 is unintentionally removed from the container main body part 1 or the lid body part 2 is lifted from the end of the main body side wall part 1a forming the main body opening 1c. It can suppress that a clearance gap produces between the body parts 2. Thereby, the cold insulation effect by the plate-shaped cold insulation material X in the accommodation space R can be maintained favorably.
また、保冷材当接部２ｆは、本体開口部１ｃに蓋体部２が取り付けられた状態で、本体側壁部１ａと板状の保冷材Ｘとの間に配置されて本体側壁部１ａ及び板状の保冷材Ｘと当接するように構成される。これにより、保冷材当接部２ｆが備える保冷材当接面２ｅと板状の保冷材Ｘとの当接による摩擦だけでなく、本体側壁部１ａと板状の保冷材Ｘとの当接による摩擦も生じることになる。このため、容器本体部１に対する蓋体部２の良好な取り付け状態をより確実に維持することができる。これにより、収容空間Ｒにおける板状の保冷材Ｘによる保冷効果をより良好に維持することができる。 Further, the cold insulation material abutting portion 2f is disposed between the main body side wall portion 1a and the plate-shaped cold insulation material X in a state where the lid portion 2 is attached to the main body opening 1c, and the main body side wall portion 1a and the plate. It is comprised so that it may contact | abut with the cold insulating material X of a shape. Thereby, not only the friction caused by the contact between the cold insulation material contact surface 2e included in the cold insulation material contact portion 2f and the plate-like cold insulation material X but also the contact between the main body side wall portion 1a and the plate-like cold insulation material X. Friction will also occur. For this reason, the favorable attachment state of the cover part 2 with respect to the container main-body part 1 can be maintained more reliably. Thereby, the cold insulation effect by the plate-shaped cold insulation material X in the accommodation space R can be maintained more favorably.
また、本体開口部１ｃに蓋体部２が取り付けられて本体側壁部１ａと板状の保冷材Ｘとの間に保冷材当接部２ｆが配置された際に、保冷材保持壁１ｅによって板状の保冷材Ｘが本体側壁部１ａ側へ押圧されるように構成される。これにより、保冷材当接部２ｆが本体側壁部１ａと板状の保冷材Ｘとに挟み込まれることになるため、本体側壁部１ａ及び板状の保冷材Ｘと保冷材当接部２ｆとの間に生じる摩擦がより大きくなる。これにより、容器本体部１に対する蓋体部２の良好な取り付け状態を更に確実に維持することができる。これにより、収容空間Ｒにおける板状の保冷材Ｘによる保冷効果を更に良好に維持することができる。 Further, when the lid portion 2 is attached to the main body opening 1c and the cold insulation material abutting portion 2f is disposed between the main body side wall portion 1a and the plate-shaped cold insulation material X, the cold insulation material retaining wall 1e is used to It is comprised so that the shape cold insulating material X may be pressed to the main body side wall part 1a side. As a result, the cold insulation material abutting portion 2f is sandwiched between the main body side wall portion 1a and the plate-like cold insulation material X, so that the main body side wall portion 1a and the plate-like cold insulation material X and the cold insulation material contact portion 2f The friction generated between them becomes larger. Thereby, the favorable attachment state of the cover part 2 with respect to the container main-body part 1 can be maintained further reliably. Thereby, the cold insulation effect by the plate-shaped cold insulation material X in the accommodation space R can be maintained more satisfactorily.
また、板状の保冷材Ｘが保冷材保持部１ｄに保持された状態で、板状の保冷材Ｘにおける本体底部１ｂ側の端部から本体開口部１ｃ側の端部へ向かって該端部間の長さの１／２以上２／３以下の領域が保冷材保持壁１ｅと重なるように構成される。ここで、収容空間Ｒにおける本体開口部１ｃの近傍の領域は、本体開口部１ｃを形成する本体側壁部１ａの端部と蓋体部２と接続部分に重なるため、外気温度の影響を受けやすい。しかしながら、上記のように構成されることで、板状の保冷材Ｘにおける保冷材保持壁１ｅと重ならない領域が本体開口部１ｃ側に形成されるため、収容空間Ｒにおける本体開口部１ｃの近傍の領域を板状の保冷材Ｘによって冷却することができる。これにより、収容空間Ｒにおける板状の保冷材Ｘによる保冷効果を良好に維持することができる。 Further, in the state where the plate-shaped cold insulation material X is held by the cold insulation material holding portion 1d, the end portion of the plate-like cold insulation material X from the end portion on the main body bottom portion 1b side toward the end portion on the main body opening portion 1c side. The region between ½ and 2/3 of the length in between is configured to overlap the cold insulation material holding wall 1e. Here, the region in the vicinity of the main body opening 1c in the accommodation space R overlaps with the end of the main body side wall 1a that forms the main body opening 1c and the connecting portion of the lid 2, so that it is easily affected by the outside air temperature. . However, since the region that does not overlap with the cold insulation material holding wall 1e in the plate-shaped cold insulation material X is formed on the main body opening 1c side by being configured as described above, the vicinity of the main body opening 1c in the accommodation space R This region can be cooled by the plate-shaped cold insulating material X. Thereby, the cold insulation effect by the plate-shaped cold insulation material X in the accommodation space R can be maintained favorably.
また、保冷材保持部１ｄは、保冷材保持壁１ｅと、該保冷材保持壁１ｅを取り付ける保持壁取付部１ｈとを備えており、該保持壁取付部１ｈに対して保冷材保持壁１ｅが着脱自在に構成される。このため、保冷材保持壁１ｅが破損したり変形したりして板状の保冷材Ｘを本体側壁部１ａ側へ押圧できなくなっても、保冷材保持壁１ｅを交換することができる。また、保冷材保持壁１ｅを交換することで、板状の保冷材Ｘを本体側壁部１ａ側へ押圧する力を調節することができる。これにより、本体側壁部１ａ及び板状の保冷材Ｘと保冷材当接部２ｆとの間に生じる摩擦を調節することができるため、容器本体部１に対する蓋体部２の着脱し易さを調節することができる。 The cold insulation material holding portion 1d includes a cold insulation material holding wall 1e and a holding wall attachment portion 1h to which the cold insulation material holding wall 1e is attached, and the cold insulation material holding wall 1e is attached to the holding wall attachment portion 1h. It is configured to be detachable. For this reason, even if the cold insulating material holding wall 1e is damaged or deformed and the plate-shaped cold insulating material X cannot be pressed toward the main body side wall 1a, the cold insulating material holding wall 1e can be replaced. Moreover, the force which presses the plate-shaped cold insulating material X to the main body side wall part 1a side can be adjusted by replacing | exchanging the cold insulating material holding wall 1e. Thereby, since the friction which arises between the main body side wall part 1a and the plate-shaped cold insulating material X and the cold insulating material contact part 2f can be adjusted, the attachment or detachment of the lid part 2 with respect to the container main body part 1 is easy. Can be adjusted.
また、保冷材保持部１ｄは、板状の保冷材Ｘにおける蓋体部２側の端部が本体開口部１ｃよりも蓋体部２側に位置し、且つ、該端部が蓋体凹部２ｃの内側に位置するように板状の保冷材Ｘを保持する。ここで、収容空間Ｒにおける本体開口部１ｃの近傍の領域と蓋体凹部２ｃの内側の領域は、外気温度の影響を受けやすい。しかしながら、上記のように構成されることで、本体開口部１ｃと重なる位置、及び、蓋体凹部２ｃの内側に板状の保冷材Ｘの一部が位置する。このため、収容空間Ｒにおける本体開口部１ｃの近傍の領域と蓋体凹部２ｃの内側の領域とを板状の保冷材Ｘによって冷却することができる。これにより、収容空間Ｒにおける板状の保冷材Ｘによる保冷効果を良好に維持することができる。 Further, the cold insulator holding portion 1d has an end on the lid body 2 side of the plate-shaped cold insulator X located on the lid body 2 side of the main body opening 1c, and the end is the lid recess 2c. The plate-shaped cold insulating material X is held so as to be located on the inside. Here, the area near the main body opening 1c and the area inside the lid recess 2c in the accommodation space R are easily affected by the outside air temperature. However, by being configured as described above, a part of the plate-shaped cold insulating material X is located at a position overlapping the main body opening 1c and inside the lid recess 2c. For this reason, it is possible to cool the region in the accommodation space R in the vicinity of the main body opening 1c and the region inside the lid recess 2c by the plate-shaped cold insulating material X. Thereby, the cold insulation effect by the plate-shaped cold insulation material X in the accommodation space R can be maintained favorably.
