Description

本発明は、断熱容器に関する。 The present invention relates to a heat insulating container.

従来から、一端が開口した金属製の外容器及び内容器を有して、外容器の内側に内容器を収容した状態で互いの開口端側が接合されると共に、外容器と内容器との間に真空断熱層が設けられた真空断熱構造を有する断熱容器がある。このような断熱容器は、保温・保冷機能を有する水筒やマグなどの飲料用容器、保温機能を有するフードコンテナや調理器などに広く利用されている。 Conventionally, a metal outer container and an inner container having one end opened are provided, and the open end sides of each other are joined with the inner container housed inside the outer container, and between the outer container and the inner container. There is a heat insulating container having a vacuum heat insulating structure provided with a vacuum heat insulating layer. Such heat-insulating containers are widely used in beverage containers such as water bottles and mugs having heat-retaining and cold-retaining functions, food containers and cookers having heat-retaining functions, and the like.

ところで、上述した断熱容器では、外容器と内容器との互いの開口端同士を突き合わせた状態で、この突き合わせ部分を溶接により接合している（例えば、下記特許文献１を参照。）。 By the way, in the above-mentioned heat insulating container, the open ends of the outer container and the inner container are butted against each other, and the butted portions are joined by welding (see, for example, Patent Document 1 below).

一方、断熱容器の中には、比較的浅底で広口となる形状のものがある。このような形状の断熱容器では、外容器と内容器との互いの開口端同士を突き合わせた状態で、これら外容器及び内容器を治具により保持することが困難である。なぜなら、このような形状の断熱容器では、外容器及び内容器の側面が緩やかに湾曲しているため、治具で保持する部分が滑り易くなっている上、外容器と内容器とが面内方向にずれ易くなっているからである。このため、接合前の外容器と内容器との位置合わせが難しく、上述した溶接加工を精度良く行うことが困難である。 On the other hand, some heat insulating containers have a relatively shallow bottom and a wide mouth. In a heat insulating container having such a shape, it is difficult to hold the outer container and the inner container with a jig in a state where the open ends of the outer container and the inner container are butted against each other. This is because, in a heat insulating container having such a shape, the side surfaces of the outer container and the inner container are gently curved, so that the portion held by the jig becomes slippery and the outer container and the inner container are in-plane. This is because it is easy to shift in the direction. Therefore, it is difficult to align the outer container and the inner container before joining, and it is difficult to perform the above-mentioned welding process with high accuracy.

一方、真空中で外容器と内容器との互いの開口端を巻き締め加工により接合する方法がある（例えば、下記特許文献２を参照。）。しかしながら、このような方法を用いた場合、上述した広口形状の断熱容器では、接合部分の厚みが厚くなるため、使い勝手が悪くなるだけでなく、見た目も悪くなってしまう。 On the other hand, there is a method of joining the open ends of the outer container and the inner container by winding in a vacuum (see, for example, Patent Document 2 below). However, when such a method is used, in the above-mentioned wide-mouthed heat insulating container, the thickness of the joint portion becomes thick, so that not only the usability is deteriorated but also the appearance is deteriorated.

以下、本発明の実施形態について、図面を参照して詳細に説明する。
本発明の一実施形態として、例えば図１〜図３に示す断熱容器１について説明する。なお、図１は、断熱容器１の構成を示す断面図である。図２は、断熱容器１の分解斜視図である。図３は、断熱容器１の外容器２と内容器３との接合端部を拡大した要部断面図である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
As an embodiment of the present invention, for example, the heat insulating container 1 shown in FIGS. 1 to 3 will be described. Note that FIG. 1 is a cross-sectional view showing the configuration of the heat insulating container 1. FIG. 2 is an exploded perspective view of the heat insulating container 1. FIG. 3 is an enlarged cross-sectional view of a main part of the heat insulating container 1 at the joint end between the outer container 2 and the inner container 3.

本実施形態の断熱容器１は、図１、図２及び図３に示すように、例えばステンレス等からなる金属製の外容器２及び内容器３を備えている。断熱容器１は、一端が開口した外容器２の内側に一端が開口した内容器３を収容した状態で、互いの開口端２ａ，３ａ側が接合されると共に、これら外容器２と内容器３との間に真空断熱層４が設けられた真空断熱構造を有している。 As shown in FIGS. 1, 2 and 3, the heat insulating container 1 of the present embodiment includes a metal outer container 2 and an inner container 3 made of, for example, stainless steel or the like. The heat insulating container 1 accommodates the inner container 3 having an open end inside the outer container 2 having an open end, and the open ends 2a and 3a are joined to each other, and the outer container 2 and the inner container 3 are joined to each other. It has a vacuum heat insulating structure in which a vacuum heat insulating layer 4 is provided between the two.

真空断熱層４は、例えば、高真空に減圧（真空引き）されたチャンバー内で、外容器の内側に内容器を収容した状態で互いの開口端が接合された容器の外容器２の底面中央部に設けられた脱気孔をろう材により封止することによって形成することができる。また、外容器２の底面中央部には、ろう材により封止された脱気孔を覆うように、円板状の保護材５が貼り付けられている。 The vacuum heat insulating layer 4 is, for example, in a chamber decompressed (evacuated) to a high vacuum, in a state where the inner container is housed inside the outer container, and the open ends are joined to each other in the center of the bottom surface of the outer container 2. It can be formed by sealing the degassing holes provided in the portion with a brazing material. Further, a disk-shaped protective material 5 is attached to the central portion of the bottom surface of the outer container 2 so as to cover the degassing holes sealed with the brazing material.

このような真空断熱構造を有することで、断熱容器１に保温や保冷といった機能を持たせることが可能である。また、断熱容器１では、このような真空断熱構造を有することで、内圧（真空圧）と外圧（大気圧）の差により外容器２及び内容器３に対して常に張力が加わった状態となり、これら外容器２及び内容器３の機械的強度が増すことになる。これにより、外容器２及び内容器３の板厚を薄くした場合でも、断熱容器１の剛性を高めることが可能であり、この断熱容器１の軽量化を図ることが可能である。 By having such a vacuum heat insulating structure, it is possible to give the heat insulating container 1 functions such as heat retention and cold retention. Further, since the heat insulating container 1 has such a vacuum heat insulating structure, tension is always applied to the outer container 2 and the inner container 3 due to the difference between the internal pressure (vacuum pressure) and the external pressure (atmospheric pressure). The mechanical strength of the outer container 2 and the inner container 3 will be increased. As a result, even when the thickness of the outer container 2 and the inner container 3 is reduced, the rigidity of the heat insulating container 1 can be increased, and the weight of the heat insulating container 1 can be reduced.

断熱容器１は、平面視で円形状となる底部１ａと、底部１ａの周囲から漸次拡径しながら上方に向かって起立した胴部１ｂとを有している。また、胴部１ｂの上部は、この断熱容器１の上部開口部１ｃとして、平面視で円形状に開口している。また、底部１ａと胴部１ｂとの間は、断面視で緩やかに湾曲している。さらに、底部１ａには、高台１ｄが設けられている。高台１ｄは、外容器２の底部において脱気孔の周囲を囲むように同心円状かつ凸状の平坦な面を形成している。 The heat insulating container 1 has a bottom portion 1a having a circular shape in a plan view, and a body portion 1b standing upward while gradually increasing the diameter from the periphery of the bottom portion 1a. Further, the upper portion of the body portion 1b is opened in a circular shape in a plan view as an upper opening portion 1c of the heat insulating container 1. Further, the bottom portion 1a and the body portion 1b are gently curved in a cross-sectional view. Further, the bottom portion 1a is provided with a hill 1d. The hill 1d forms a concentric and convex flat surface at the bottom of the outer container 2 so as to surround the degassing hole.

このように、本実施形態の断熱容器１は、全体として比較的浅底で広口形状を有している。また、真空断熱層４は、外容器２の底部と内容器３の底部との間から外容器２の胴部と内容器３の胴部との間に亘って設けられている。 As described above, the heat insulating container 1 of the present embodiment has a relatively shallow bottom and a wide mouth shape as a whole. Further, the vacuum heat insulating layer 4 is provided from between the bottom of the outer container 2 and the bottom of the inner container 3 to the body of the outer container 2 and the body of the inner container 3.

本実施形態の断熱容器１は、図３に一部を拡大して示すように、外容器２の開口端２ａを含む第１の接合端部６と、内容器３の開口端３ａを含む第２の接合端部７とを備えている。つまり、第１の接合端部６は内容器３の開口端３ａ及びその付近に設けられ、第２の接合端部７は外容器２の開口端２ａ及びその付近に設けられている。断熱容器１では、これら第１の接合端部６と第２の接合端部７とを接合することによって、この断熱容器１の接合端部１ｅが構成されている。 As shown in a partially enlarged view of FIG. 3, the heat insulating container 1 of the present embodiment has a first joint end portion 6 including an open end 2a of the outer container 2 and a second including the open end 3a of the inner container 3. It is provided with a joint end portion 7 of 2. That is, the first joint end portion 6 is provided at the opening end 3a of the inner container 3 and its vicinity, and the second joint end portion 7 is provided at the opening end 2a of the outer container 2 and its vicinity. In the heat insulating container 1, the joint end portion 1e of the heat insulating container 1 is formed by joining the first joint end portion 6 and the second joint end portion 7.

具体的に、第１の接合端部６は、外容器２の上部開口部から全周に亘って拡径方向に突出されたフランジ形状を有している。第１の接合端部６は、外容器２の上部開口部から外容器２の開口端２ａに向かって平坦な面を形成している。 Specifically, the first joint end portion 6 has a flange shape protruding from the upper opening of the outer container 2 in the diameter-expanding direction over the entire circumference. The first joint end portion 6 forms a flat surface from the upper opening of the outer container 2 toward the opening end 2a of the outer container 2.

第２の接合端部７は、内容器３の上部開口部から全周に亘って拡径方向に突出されたフランジ形状を有している。具体的には、第２の接合端部７は、フランジ形状の天面部９と、変曲部分７ａにより内容器３の開口端３ａを下側に折り返したフランジ形状の折返部８とを有している。つまり、第２の接合端部７は、折返部８である下部と、天面部９である上部とを有する。なお、第２の接合端部７の変曲部分７ａは、断熱容器１の開口端１ｆとなっている。 The second joint end portion 7 has a flange shape protruding in the diameter-expanding direction from the upper opening of the inner container 3 over the entire circumference. Specifically, the second joint end portion 7 has a flange-shaped top surface portion 9 and a flange-shaped folded portion 8 in which the open end 3a of the inner container 3 is folded downward by the inflection point 7a. ing. That is, the second joint end portion 7 has a lower portion that is a folded portion 8 and an upper portion that is a top surface portion 9. The inflection point 7a of the second joint end portion 7 is the open end 1f of the heat insulating container 1.

第２の接合端部７は、外容器２の上部開口部から折返部８に向かって平坦な面を形成している。また、内容器３の開口端３ａは、折返部８により外容器２の開口端２ａと突き合わされる位置まで折り返されている。 The second joint end portion 7 forms a flat surface from the upper opening of the outer container 2 toward the folded-back portion 8. Further, the open end 3a of the inner container 3 is folded back to a position where it is abutted with the open end 2a of the outer container 2 by the folded portion 8.

本実施形態の断熱容器１では、第２の接合端部７が第１の接合端部６よりも、容器の半径方向において外側に位置すると共に、第１の接合端部６と、第２の接合端部７の天面部９とを上下方向に突き合わせた状態で、開口端２ａと開口端３ｂとが互いに突き合わされた部分を接合することで、第１の接合端部と、第２の接合端部７とは接合されている。 In the heat insulating container 1 of the present embodiment, the second joint end portion 7 is located outside the first joint end portion 6 in the radial direction of the container, and the first joint end portion 6 and the second joint end portion 6 are located. The first joint end and the second joint are joined by joining the portions where the opening ends 2a and the opening ends 3b are butted against each other in a state where the top surface portion 9 of the joint end portion 7 is abutted in the vertical direction. It is joined to the end portion 7.

第１の接合端部６と第２の接合端部７との接合には、例えばレーザー溶接などの溶接方法が用いられる。 A welding method such as laser welding is used for joining the first joint end portion 6 and the second joint end portion 7.

これにより、本実施形態の断熱容器１では、第２の接合端部７の天面部９、より具体的には天面部９の下面において、第１の接合端部６と第２の接合端部７とが接合されて一体化されている。したがって、この断熱容器１の接合端部１ｅは、上部開口部１ｃから全周に亘って拡径方向に突出されたフランジ形状を有している。 As a result, in the heat insulating container 1 of the present embodiment, the first joint end portion 6 and the second joint end portion are on the top surface portion 9 of the second joint end portion 7, more specifically, on the lower surface of the top surface portion 9. 7 is joined and integrated. Therefore, the joint end portion 1e of the heat insulating container 1 has a flange shape protruding from the upper opening 1c over the entire circumference in the diameter-expanding direction.

なお、図３は溶接前の容器を示すため、第１の接合端部６と第２の接合端部７との突き合わせ部分である開口端２ａ，３ａが図示されているが、接合後は、この突き合わせ部分が溶接により溶融することで、第２の接合端部７の天面部９に全周に亘って溶接ビードが形成されることになる。溶接加工の後に、形成された溶接ビードに研削及び研磨加工を施すことによって、平坦な面に仕上げられる。 In addition, since FIG. 3 shows the container before welding, the opening ends 2a and 3a, which are the abutting portions between the first joint end portion 6 and the second joint end portion 7, are shown. When the butt portion is melted by welding, a weld bead is formed on the top surface portion 9 of the second joint end portion 7 over the entire circumference. After the welding process, the formed weld bead is ground and polished to finish a flat surface.

また、図３では、第１の接合端部６と第２の接合端部７との突き合わせ部分である開口端２ａ，３ａが接合可能なクリアランスの範囲で離間している。このクリアランスは、溶接により形成されるビード幅を考慮して定められればよく、互いの開口端２ａ，３ａが当接した状態で、この突き合わせ部分を溶接により接合することも可能である。 Further, in FIG. 3, the opening ends 2a and 3a, which are the abutting portions between the first joint end portion 6 and the second joint end portion 7, are separated within a range of clearance that can be joined. This clearance may be determined in consideration of the bead width formed by welding, and it is also possible to join the butt portions by welding while the opening ends 2a and 3a are in contact with each other.

なお、上記実施形態では、第１の接合端部６と第２の接合端部７との突き合わせ部分である開口端２ａ，３ａを溶接しているが、外容器２の開口端２ａと第２の接合端部７の天面部９とを溶接により接合してもよい。 In the above embodiment, the opening ends 2a and 3a, which are the abutting portions between the first joint end portion 6 and the second joint end portion 7, are welded, but the opening ends 2a and the second of the outer container 2 are welded. The top surface portion 9 of the joint end portion 7 of the above may be joined by welding.

この場合、外容器２の中心と内容器３の中心とがずれて、外容器２の開口端２ａと内容器３の開口端３ａとのクリアランスにおいて、一方向が広く他方向が狭くなったとしても、外容器２の開口端２ａと第２の接合端部７の天面部９とを接合すれば、真空断熱層４となる閉空間を形成することが可能となる。 In this case, assuming that the center of the outer container 2 and the center of the inner container 3 are deviated from each other, the clearance between the opening end 2a of the outer container 2 and the opening end 3a of the inner container 3 is wide in one direction and narrow in the other direction. However, if the open end 2a of the outer container 2 and the top surface portion 9 of the second joint end portion 7 are joined, a closed space serving as the vacuum heat insulating layer 4 can be formed.

また、外容器２の開口端２ａの外径が所定の大きさよりも小さく形成され、開口端２ａ，３ａのクリアランスが全周において広くなったとしても、上記の場合と同様に、外容器２の開口端２ａと第２の接合端部７の天面部９とを接合すれば、真空断熱層４となる閉空間を形成することが可能となる。 Further, even if the outer diameter of the opening end 2a of the outer container 2 is formed to be smaller than a predetermined size and the clearance of the opening ends 2a and 3a is widened over the entire circumference, the outer container 2 has the same as the above case. By joining the open end 2a and the top surface portion 9 of the second joint end portion 7, it is possible to form a closed space that becomes the vacuum heat insulating layer 4.

したがって、本実施形態の断熱容器１では、外容器２と内容器３との厳密な位置合わせやサイズ調整を行う必要がない。また、第１の接合端部６と第２の接合端部７の天面部９とが互いに面接触しているため、溶接ビードを幅広く取ることが可能である。これにより、外容器２及び内容器３の板厚が薄いものや、外容器２及び内容器３のサイズが大きいものであっても適切に接合することが可能である。 Therefore, in the heat insulating container 1 of the present embodiment, it is not necessary to strictly align the outer container 2 and the inner container 3 and adjust the size. Further, since the first joint end portion 6 and the top surface portion 9 of the second joint end portion 7 are in surface contact with each other, it is possible to take a wide range of weld beads. As a result, even if the outer container 2 and the inner container 3 have a thin plate thickness or the outer container 2 and the inner container 3 have a large size, they can be appropriately joined.

以上のように、本実施形態の断熱容器１では、上述した第１の接合端部６と第２の接合端部７の天面部９とが上下方向に突き合わされた状態で、第１の接合端部６と第２の接合端部７とが接合されている。 As described above, in the heat insulating container 1 of the present embodiment, the first joint is joined in a state where the first joint end portion 6 and the top surface portion 9 of the second joint end portion 7 described above are butted in the vertical direction. The end portion 6 and the second joint end portion 7 are joined.

これにより、浅底で広口となる形状を有する断熱容器１であっても、接合の際に第１の接合端部６と第２の接合端部７の天面部９とを上下方向に突き合わせることによって、外容器２及び内容器３を上下方向から押し付けるように固定すればよく、治具により安定した状態で保持することが可能である。 As a result, even in the heat insulating container 1 having a shallow bottom and a wide mouth shape, the first joint end portion 6 and the top surface portion 9 of the second joint end portion 7 are abutted in the vertical direction at the time of joining. As a result, the outer container 2 and the inner container 3 may be fixed so as to be pressed from above and below, and can be held in a stable state by a jig.

さらに、本実施形態の断熱容器１では、上述した第２の接合端部７の天面部９において、内容器３の開口端３ａと外容器２の開口端２ａとが突き合わされた状態となっている。これにより、接合の際に外容器２と内容器３とが面内方向にずれるといったことを防ぐことが可能である。 Further, in the heat insulating container 1 of the present embodiment, the open end 3a of the inner container 3 and the open end 2a of the outer container 2 are abutted against each other on the top surface 9 of the second joint end 7 described above. There is. As a result, it is possible to prevent the outer container 2 and the inner container 3 from being displaced in the in-plane direction at the time of joining.
