Description

本発明は、独立請求項による食品の温度管理された（例えば冷却された）輸送のための真空断熱積み重ね容器に関する。 The present invention relates to a vacuum-insulated stacking container for temperature-controlled (e.g. chilled) transport of food products according to the independent claim.

このタイプの積み重ね容器は、実際において広く知られており、例えば輸送のためだけでなく保管のためにもプラスチックボックスの形でパン屋のパンを取り扱う際に使用される。これらのプラスチックボックスは、充填した状態と充填していない状態で積み重ねることができる。 Stacking containers of this type are widely known in practice and are used, for example, in the handling of bread in bakeries in the form of plastic boxes not only for transport but also for storage. These plastic boxes can be stacked in filled and unfilled states.

このようなプラスチックボックスは、容器底を４辺で全周包囲する容器壁を備えており、それによってパン又は同類のものを入れることができる一側が開いた容器空間が生じる。 Such plastic boxes are provided with a container wall which encircles the container bottom on four sides, thereby creating a container space open on one side into which bread or the like can be placed.

容器壁の開いた縁部と底部はそれぞれ全周を囲んで互いに噛み合う端縁部で形成されている。そのため上にあるプラスチックボックスの容器底の端縁部は、その下にあるプラスチックボックスの容器壁に当接して、積み重ねたプラスチックボックスが滑って位置がずれないように固定できる。 The open edge and the bottom of the container wall are each formed with edges that interlock around the entire circumference. The edge of the bottom of the container of the upper plastic box can therefore abut against the container wall of the lower plastic box to secure the stacked plastic boxes from slipping out of position.

このようなプラスチックボックスの問題は、断熱性がないために使用が制限されている点である。特にいわゆるベーカリーチェーン店に商品が適温状態で納入されるケースがますます増えているので、断熱材のない従来のプラスチックボックスは冷却冷蔵ユニットのない配送車両での輸送には使用できない。冷却装置を内蔵した車両でもチェーン店に搬入する間に温度の影響が大幅に増加する。この場合、プラスチックボックスで保管又は輸送される食品は過大な温度変動を被り、そのためにもはや使用できなくなったり、腐ったりするリスクがある。 The problem with such plastic boxes is that they are of limited use due to their lack of insulation. Conventional plastic boxes without insulation cannot be used for transport in delivery vehicles without cooling and refrigerating units, especially since the goods are increasingly being delivered in moderate temperature conditions, especially to so-called bakery chains. Even vehicles with built-in cooling systems experience significantly increased temperature effects during delivery to chain stores. In this case, food stored or transported in plastic boxes is subjected to excessive temperature fluctuations and therefore risks being no longer usable or spoiling.

食品を輸送するためのプラスチックボックスに断熱材がない問題は、肉製品の輸送においても同様に生じる。ここでは精肉店内での取り扱い中に冷却が不十分になるリスクがある。この問題は、食品を取り扱う他の多くの分野でも当てはめることができる。 The problem of lack of insulation in plastic boxes for transporting food also arises in transporting meat products. Here there is a risk of insufficient cooling during handling in the butcher shop. This problem can also be applied to many other areas of food handling.

断熱性を有する積み重ね可能な容器は、特許文献１に示されている。原則としてそこに記載されている輸送容器は、温度に敏感な食品（例えばパン、肉製品、魚など）に使用することができる。輸送容器は、内部容器と外部容器からなる下部からなり、内部容器と外部容器の間に断熱材が配置されている。下部の上には閉鎖可能な蓋が配置されており、積み重ねを可能にするために蓋の上側は閉じた状態で輸送容器の下側に対して相補的に設計されている。上記のプラスチックボックスとは異なり、この輸送容器は蓋が装備されているため、積み重ねるときに上側容器の下側が閉じた蓋の上に置かれる。原則としてこれにより垂直方向に、食品輸送での通常の使用に必要とされない余分な断熱が生じる。 A thermally insulated stackable container is shown in US Pat. In principle, the transport containers described there can be used for temperature-sensitive foodstuffs (eg bread, meat products, fish, etc.). The transport container consists of a lower portion consisting of an inner container and an outer container, and a heat insulating material is arranged between the inner container and the outer container. A closable lid is positioned over the lower portion and is designed complementary to the underside of the shipping container with the top side of the lid closed to allow stacking. Unlike the plastic boxes mentioned above, this shipping container is equipped with a lid so that the underside of the upper container rests on the closed lid when stacked. In principle this results in extra insulation in the vertical direction which is not required for normal use in food transport.

独国実用新案第２０２０１６００１０９７（Ｕ１）号明細書German Utility Model No. 202016001097 (U1)

本発明の課題は、従来技術の不利な点を克服し、特に構造が単純で、輸送のために便利に取り扱うことができる積み重ね容器を提供することである。 SUMMARY OF THE INVENTION It is an object of the present invention to overcome the disadvantages of the prior art and to provide a stacking container that is particularly simple in construction and can be conveniently handled for transport.

上記の課題は、独立請求項による食品の温度管理された輸送のための積み重ね容器によって解決される。従属請求項に有利な実施形態が記載されている。 The above problem is solved by a stacking container for temperature-controlled transport of food products according to the independent claim. Advantageous embodiments are described in the dependent claims.

本発明は、食品の温度管理された輸送のための（真空断熱された）積み重ね容器を含む。積み重ね容器は、外部容器底と外部容器壁を備えた外部容器を有しており、外部容器底と外部容器壁は一側が開いた収容空間を形成するように互いに接合している。さらに、積み重ね容器は、内部容器底と内部容器壁を備えた内部容器を有しており、内部容器底と内部容器壁は一側が開いた容器空間を形成するように相互に接合している。内部容器壁は上縁部を有し、外部容器底には下縁部を有しており、上縁部と下縁部は容器を上下に積み重ねたときに互いに噛み合うように相補的に設計されている。内部容器壁と外部容器壁との間、及び内部容器底と外部容器底との間には、真空断熱要素が配置されている。上記の上縁部の設計により、その上にある積み重ね容器の下縁部と確実に噛み合うことができるので、多数の積み重ね容器を確実に積み重ねることができる。内部容器底と外部容器底との間に真空断熱要素を配置することにより、上側容器の底部が下側容器の容器空間を閉じることによって、積み重ねた積み重ね容器で断熱された蓋が提供される。真空断熱要素は真空断熱パネル（ＶＩＰ）であることが好ましく、これは例えば欧州特許出願公開第２７００８９１（Ａ２）号明細書又は独国特許出願公開第２０２０１４００４５１５（Ｕ１）号明細書に記載されている。このようにして積み重ね容器システムは、上下に積み重ねて配置された少なくとも２つの積み重ね容器から作成することができ、上にある積み重ね容器の外底が下にある積み重ね容器の容器空間の上側を閉じる。これにより高度に断熱された積み重ね可能なコンパートメントが得られ、熱伝導率が０．５Ｗ／Ｋ未満と良好な熱システムが実現する。これは約０．６１Ｗ／（ｍ2Ｋ）の熱伝達係数（Ｕ値）に相当する（蓋面を含み、外面に基づくすべての熱橋を含む）。原則として真空断熱要素による非常に優れた断熱によって得られる温度保持時間は、約６時間の輸送時間を達成するのに十分である。輸送時間を、例えば最大２４時間まで延ばすために、温度保持時間を相応に長くする相変化材料（ＰＣＭ）を導入することができる。商品に機械的ストレスを与えるのを防ぐために、（ＰＣＭ）アキュムレータ（側面及び／又は蓋）を保持具によってライナー内に固定して落下を防ぐ。ボックスのスタックの閉鎖部材として、或は個々のボックスが納入される場合、若しくは配達後の待ち時間が長い場合は、真空断熱要素を含んだ追加の蓋を配置できる。 The present invention includes a (vacuum insulated) stacking container for temperature controlled transportation of food products. The stacking container has an outer container with an outer container bottom and an outer container wall, the outer container bottom and the outer container wall joining together to form a receiving space open on one side. Further, the stacked container has an inner container with an inner container bottom and an inner container wall, the inner container bottom and the inner container wall joining together to form an open-sided container space. The inner container wall has an upper edge and the outer container bottom has a lower edge, the upper and lower edges being complementary designed to interlock when the containers are stacked one on top of the other. ing. Vacuum insulation elements are positioned between the inner and outer container walls and between the inner and outer container bottoms. The design of the top edge ensures that it can be mated with the bottom edge of an overlying container stack, thus allowing multiple stacks to be stacked securely. By placing a vacuum insulation element between the bottom of the inner container and the bottom of the outer container, the bottom of the upper container closes the container space of the lower container to provide an insulated lid on the stacked stacked container. The vacuum insulation element is preferably a vacuum insulation panel (VIP), which is described for example in EP 2700891 A2 or DE 202014004515 U1. . In this way, a stacked container system can be made up of at least two stacked containers arranged one above the other, with the outer bottom of the upper stacked container closing the upper side of the container space of the underlying stacked container. This results in highly insulated stackable compartments and a good thermal system with a thermal conductivity of less than 0.5 W/K. This corresponds to a heat transfer coefficient (U-value) of approximately 0.61 W/(m 2 K) (including lid surface and all thermal bridges based on the outer surface). The temperature holding time obtained in principle by the very good insulation provided by vacuum insulation elements is sufficient to achieve a transport time of approximately 6 hours. In order to extend the transport time, for example up to 24 hours, a phase change material (PCM) can be introduced which correspondingly increases the temperature holding time. To prevent mechanical stress on the product, the (PCM) accumulator (sides and/or lid) is secured within the liner by retainers to prevent falling. Additional lids containing vacuum insulation elements can be provided as closures for stacks of boxes, or if individual boxes are delivered or if the waiting time after delivery is long.

有利な態様によれば、内部容器壁は上縁部に、及び外部容器底は下縁部に、それぞれＬ字型ストッパを備える。Ｌ字型の構成により上縁部と下縁部を簡単に相補的に設計できるため、上縁部と下縁部は滑らないようにロックされている。 According to an advantageous embodiment, the inner container wall at the upper edge and the outer container bottom at the lower edge each comprise an L-shaped stopper. The L-shaped configuration allows for a simple complementary design of the top and bottom edges so that they are locked against slippage.

Ｌ字型ストッパはそれぞれ上縁部と下縁部で、それぞれ最小長さ０．５ｃｍの第１の輪郭部と（それに直角に配置された）第２の輪郭部を有することが有利である。 Advantageously, the L-shaped stops each have a first contour and a second contour (disposed at right angles thereto) of minimum length 0.5 cm, respectively, at the upper and lower edges.

特に好ましくは、内部容器壁は、上縁部で完全に全周を囲む突出部を備えており、突出部は挿入された状態で外部容器壁を少なくとも部分的に覆う大きさと形状を有する。 Particularly preferably, the inner container wall is provided with a projection which completely surrounds the entire circumference at the upper edge, the projection being sized and shaped to at least partially cover the outer container wall in the inserted state.

内部容器の突出部は、外部容器壁と全周で堅固に接合していることが有利である。 Advantageously, the projection of the inner container is firmly connected to the outer container wall all around.

堅固な結合を達成するために、内部容器の突出部と外部容器壁は、好ましくは熱的に接合可能なプラスチック材料でできている。プラスチックは、例えばポリウレタン、ポリプロピレン又はポリエチレンを含むことができる。この場合、内部容器の突出部分は、外側の容器壁に溶着されている。 In order to achieve a firm connection, the projection of the inner container and the outer container wall are preferably made of a thermally bondable plastics material. Plastics can include, for example, polyurethane, polypropylene or polyethylene. In this case, the projecting portion of the inner container is welded to the outer container wall.

代替例によると、内部容器の突出部は外部容器壁と接着されている。代替例によれば、熱的に接合可能な材料も接合不可能な材料も接着により接合することができる。 According to an alternative, the protrusion of the inner container is glued to the outer container wall. According to an alternative, both thermally bondable and non-bondable materials can be bonded by adhesion.

さらに、内部容器壁は、内部容器底を起点として垂直に延びるように、又は互いに円錐状に広がるように配置されていることが好ましい。特に真空断熱要素が一体的な真空断熱パネルで、内部容器底又は外部容器底の延び方に従って折りたたまれている場合、内部容器底と外部容器底との間の距離がより大きく、内部容器壁と外部容器壁との間の距離がより小さいと、組み立てに有利である。 Furthermore, the inner container walls are preferably arranged such that they extend vertically starting from the inner container bottom or diverge conically from one another. Especially when the vacuum insulation element is an integral vacuum insulation panel and is folded according to the extension of the inner container bottom or the outer container bottom, the distance between the inner container bottom and the outer container bottom is greater and the inner container wall and A smaller distance to the outer container wall is advantageous for assembly.

別の有利な態様によれば、内部容器の底面の大きさは外部容器の底面の大きさの少なくとも７０％の大きさである。真空断熱パネルの優れた断熱性に基づき、内部容器の底面と外部容器の底面との間の空間を小さく保つことができるため、外部容器の底面と比較して同様に大きい内部容器の底面が提供される。 According to another advantageous embodiment, the size of the bottom surface of the inner container is at least 70% of the size of the bottom surface of the outer container. Based on the excellent insulation properties of the vacuum insulation panels, the space between the bottom of the inner vessel and the bottom of the outer vessel can be kept small, thus providing an equally large bottom of the inner vessel compared to the bottom of the outer vessel. be done.

真空断熱要素は単一の（一体的な）真空断熱パネルであることが特に好ましい。真空断熱パネルは少なくとも１つの折り目を有する。 It is particularly preferred that the vacuum insulation element is a single (integral) vacuum insulation panel. The vacuum insulation panel has at least one crease.

外部容器底は有利には、その下にある積み重ね容器の上縁部を完全に囲んで閉じるための大きさと形状を有する。有利な例では、容器間の閉鎖が、対流が防止されるように設計されている。 The outer container bottom is advantageously sized and shaped to completely enclose and close the upper edge of the underlying stack of containers. Advantageously, the closures between the containers are designed to prevent convection.

この態様の１つの可能な実施形態は、外部容器底が底部構造に十分な高さの段差を有しており、その結果として２つの積み重ね容器を積み重ねた状態で下にある上縁部に深く突入して、熱の熱経路が十分に延長され、かつ対流が減少するようにされている。 One possible embodiment of this aspect is that the outer container bottom has a step of sufficient height in the bottom structure so that the two stacked containers are deep into the underlying top edge in the stacked state. Intrusions are made so that the thermal path of the heat is sufficiently extended and convection is reduced.

以下に本発明を、添付の図面に示された例を参照してより詳細に説明する。 In the following, the invention will be explained in more detail with reference to the examples shown in the accompanying drawings.

図１は、本発明による積み重ね容器１の例示的な実施形態の外部容器３と内部容器２の詳細図を示している。 Figure 1 shows a detailed view of the outer container 3 and the inner container 2 of an exemplary embodiment of a stacked container 1 according to the invention.

外部容器３は、外部容器底３１と、そこから上方に延びる外部容器壁３２とを備える。外部容器壁３２と外部容器底３１は、一体的に形成されているか、若しくは製造工程においてプラスチック材料から成形されている。このように成形された外部容器３は、一側が上方に向かって開いた収容空間３３を有し、その中に内部容器２をほぼ完全に押し込むことができるので、外部容器３の内側と内部容器２の外側との間に真空断熱要素のための完全に閉じられた収容空間が形成されている。 The outer container 3 comprises an outer container bottom 31 and an outer container wall 32 extending upwardly therefrom. The outer container wall 32 and the outer container bottom 31 are either integrally formed or molded from a plastics material during the manufacturing process. The outer container 3 molded in this way has a receiving space 33 open on one side upwards, into which the inner container 2 can be almost completely pushed, so that the inside of the outer container 3 and the inner container are separated. 2 forms a completely closed receiving space for the vacuum insulation element.

内部容器２は、単一の材料から一体的に形成され互いに接合している内部容器底２１と内部容器壁２２を有する。それにより温度管理された輸送を目的とした食品を受け入れるのに適した、一側が開いた容器空間２３が形成される。 The inner container 2 has an inner container bottom 21 and an inner container wall 22 integrally formed from a single piece of material and joined together. An open-sided container space 23 is thereby formed which is suitable for receiving food products intended for temperature-controlled transport.

確実で安定した方法での積み重ねを保証するために、内部容器壁２２は上部に完全に全周を囲むＬ字型のストッパを備えた縁部２２１を有する。 In order to ensure stacking in a secure and stable manner, the inner container wall 22 has at the top an edge 221 with a completely encircling L-shaped stop.

外部容器底３１は下縁部（この斜視図では見えない。図２を参照）を有し、これは積み重ね容器１を互いに積み重ねたときに、下にある積み重ね容器１の内部容器壁２２の上縁部２２１に設けたＬ字型ストッパに当接するように相補的に設計されている。 The outer container bottom 31 has a lower edge (not visible in this perspective view, see FIG. 2) which, when the container stacks 1 are stacked on top of each other, is positioned above the inner container wall 22 of the underlying container stack 1 .
