Definitions
- the invention relates to an insulation container for receiving temperature-sensitive products according to the independent claim.
- Thermal insulation means the reduction of passage of thermal energy through a shell to protect a space or body from cooling down or being heated.
- insulation containers for receiving temperature-sensitive products, which are equipped with at least one insulation element.
- This insulation element is connected via at least two connecting surfaces to form an insulation container.
- the insulation containers for example, consist of a flexible material or of boards which are connected to each other.
- Containers of this type provide passive thermal protection for valuable temperature-sensitive products, such as pharmaceutical products. This is particularly crucial because the standards for storage and transport of pharmaceutical products, for example, are very high and must be demonstrably maintained throughout the entire supply chain.
- Thermal conduction means the transport of heat in a medium without mass transfer (as is the case in convection, for example).
- Materials with low thermal conductivity are referred to as thermal insulation materials and are used to reduce heat or cold losses.
- thermal bridges may occur at the abutting surfaces where the individual boards are connected to each other, where undesired exchange of heat between the interior of the insulation container and the environment occurs.
- Thermal bridges arise particularly strongly, for example, due to manufacturing tolerances resulting from the production of the boards or uneven surfaces, which lead to corresponding opening gaps at the connecting surfaces.
- Heat exchange (or heat transfer) is a physical process taking place between at least two media, during which the thermal energy of the medium with the higher temperature is transferred to another medium with a lower temperature. Heat exchange results in heating or cooling of a substance system or evaporation or condensation or freezing or melting of a substance. This results in deterioration of the insulation properties of the container and heating or cooling of the temperature-sensitive products placed inside the insulation container. Leakage in insulation may lead to serious loss of time and resources within the supply chain. The products may then under some circumstances no longer be usable, or only usable to a limited extent.
- the invention pertains to the technical field of insulation of containers for receiving products to be stored or transported at specific temperatures, in particular the improvement of thermal insulation of such containers.
- the invention has the object of providing an insulation container which overcomes the disadvantages in prior art and, in particular, enables improved sealing of the insulation containers and thus reduced heat exchange along the connecting surfaces.
- the invention encompasses an insulation container for receiving temperature-sensitive products.
- the insulation container is equipped with at least one vacuum insulation element.
- This vacuum insulation element is connected via at least two connecting surfaces.
- a sealing means is disposed at the connecting surfaces to reduce heat exchange along the connecting surfaces by closing and sealing, respectively, of the opening gaps created between the vacuum insulation elements. This enables improved sealing of the insulation containers and thus reduced heat exchange in the region of the connecting surfaces. Thermal bridges created due to manufacturing tolerances resulting from the production of the boards or uneven surfaces, which lead to corresponding opening gaps at the connecting surfaces, are thus reduced.

- the sealing means can be disposed in a narrow strip along the connecting surface which extends over only a part of the width of the connecting surface.
- the sealing means is designed to be flexibly deformable. This allows any gaps that may exist to be compensated for when the boards are exposed to a certain amount of pressure against each other.
- the thickness of the sealing means is in the range from 0.5 mm to 10 mm, in particular 2 mm to 4 mm, because manufacturing tolerances above these ranges do not usually occur.
- the sealing means is disposed laterally at the abutment joint of the connecting surfaces in each case completely or partially along the connecting face.
- a coated (aluminium) foil can be employed as the sealing means.
- the sealing means is designed in each case in one piece or in multiple pieces at the connecting surfaces.
- the sealing means is designed in one piece, with a precise fit in conformity with the connecting surface.
- the sealing means is designed in multiple parts and can thus be disposed several times in succession in the direction of heat transfer, for example in the form of parallel strips.
- the sealing means comprises an adhesive, in particular an adhesive tape, a bonding agent, spray latex, or a combination thereof.
- the sealing means may hold the connecting surfaces together due to adhesion, thereby increasing the stability of the insulation container while reducing the passage of air to reduce heat exchange at the connecting surfaces.
- the sealing means comprises a heat transfer minimizing material, particularly a thermal insulation material, a swelling tape, foam material, or a combination thereof.
- a thermal insulation material is an insulation foam.
- the swelling tape may be made of a thermal insulation material and simultaneously minimize air passage at the connecting surfaces.
- the insulation container further comprises four side insulation elements, a bottom insulation element, and a lid insulation element.
- the four side insulation elements and the bottom insulation element are brought into abutment with each other along the respective connecting surfaces in such a way as to form a receiving space which is open on one side for receiving the temperature-sensitive products.

- the vacuum insulation elements comprise a vacuum insulation panel.
- the connecting surfaces formed at the abutment joints can be sealed in an advantageous manner.
- vacuum insulation panels of the vacuum insulation elements are each embodied as a single layer or as multiple layers. If several layers of vacuum insulation panels are used, adjacent connection abutment joints can also be sealed separately.
- the insulation container further comprises a sheathing which completely or partially surrounds the insulation container, the product or the vacuum insulation elements.
- a sheathing made of foil prevents water vapor and air from reaching between the vacuum insulation elements.
- corner elements are disposed at the outer edges of the insulation container formed along the connecting surfaces. These corner elements are designed in such a way as to at least partially enclose the outer side of the vacuum insulation elements. In this way, the insulation container can be protected from impacts and associated damage caused to the products located in the insulation container.
- At least one strap for stabilizing the vacuum insulation elements is disposed along the outer sides of the vacuum insulation elements. This allows the vacuum insulation elements to be held firmly together and, for example, due to the elasticity of the strap, contact pressure can be applied in such a way as to press the connecting surfaces together.

Abstract
Description
- This patent application claims priority to German utility patent application number 20 2020 107 477.6 filed Dec. 22, 2020 and titled “insulation container for receiving temperature-sensitive products”. The subject matter of patent application number 20 2020 107 477.6 is hereby incorporated by reference in its entirety.

- Not Applicable.
- The invention relates to an insulation container for receiving temperature-sensitive products according to the independent claim.
- Thermal insulation means the reduction of passage of thermal energy through a shell to protect a space or body from cooling down or being heated.
- It is known from prior art to provide insulation containers for receiving temperature-sensitive products, which are equipped with at least one insulation element. This insulation element is connected via at least two connecting surfaces to form an insulation container. The insulation containers, for example, consist of a flexible material or of boards which are connected to each other. Containers of this type provide passive thermal protection for valuable temperature-sensitive products, such as pharmaceutical products. This is particularly crucial because the standards for storage and transport of pharmaceutical products, for example, are very high and must be demonstrably maintained throughout the entire supply chain.
- The insulation elements used should have the lowest possible thermal conductivity λ in order to achieve a good thermal insulation effect. Thermal conduction means the transport of heat in a medium without mass transfer (as is the case in convection, for example). Materials with low thermal conductivity are referred to as thermal insulation materials and are used to reduce heat or cold losses.
- However, thermal bridges may occur at the abutting surfaces where the individual boards are connected to each other, where undesired exchange of heat between the interior of the insulation container and the environment occurs. Thermal bridges arise particularly strongly, for example, due to manufacturing tolerances resulting from the production of the boards or uneven surfaces, which lead to corresponding opening gaps at the connecting surfaces. Heat exchange (or heat transfer) is a physical process taking place between at least two media, during which the thermal energy of the medium with the higher temperature is transferred to another medium with a lower temperature. Heat exchange results in heating or cooling of a substance system or evaporation or condensation or freezing or melting of a substance. This results in deterioration of the insulation properties of the container and heating or cooling of the temperature-sensitive products placed inside the insulation container. Leakage in insulation may lead to serious loss of time and resources within the supply chain. The products may then under some circumstances no longer be usable, or only usable to a limited extent.
- The invention pertains to the technical field of insulation of containers for receiving products to be stored or transported at specific temperatures, in particular the improvement of thermal insulation of such containers. The invention has the object of providing an insulation container which overcomes the disadvantages in prior art and, in particular, enables improved sealing of the insulation containers and thus reduced heat exchange along the connecting surfaces.
- This object is achieved by an insulation container for receiving temperature-sensitive products having the features of the independent claim. Advantageous embodiments form the subject-matter of the associated subclaims.
- The invention encompasses an insulation container for receiving temperature-sensitive products. The insulation container is equipped with at least one vacuum insulation element. This vacuum insulation element is connected via at least two connecting surfaces. A sealing means is disposed at the connecting surfaces to reduce heat exchange along the connecting surfaces by closing and sealing, respectively, of the opening gaps created between the vacuum insulation elements. This enables improved sealing of the insulation containers and thus reduced heat exchange in the region of the connecting surfaces. Thermal bridges created due to manufacturing tolerances resulting from the production of the boards or uneven surfaces, which lead to corresponding opening gaps at the connecting surfaces, are thus reduced.
- In the following, the invention will be explained in greater detail with reference to drawings, wherein:
-
FIG. 1 shows an exploded view of an insulation container according to the invention; -
FIG. 2 shows an exploded view of the insulation container ofFIG. 1 in a partially connected state; -
FIG. 3 shows a side view of the insulation container ofFIG. 1 in a completely closed state with a sheating; -
FIG. 4 shows a sectional view through a vacuum insulation element with a sheathing; -
FIG. 5 shows an exploded view of the insulation container ofFIG. 1 with corner elements; and -
FIG. 6 shows an exploded view of the insulation container ofFIG. 1 with corner elements and straps for stabilizing the vacuum insulation elements. - According to an advantageous aspect, the sealing means is disposed between the connecting surfaces in each case completely or partially along the connecting surface. For example, the sealing means can be disposed in a narrow strip along the connecting surface which extends over only a part of the width of the connecting surface.
- Preferably, the sealing means is designed to be flexibly deformable. This allows any gaps that may exist to be compensated for when the boards are exposed to a certain amount of pressure against each other. Preferably, the thickness of the sealing means is in the range from 0.5 mm to 10 mm, in particular 2 mm to 4 mm, because manufacturing tolerances above these ranges do not usually occur.
- It has proven to be a technically good alternative if the sealing means is disposed laterally at the abutment joint of the connecting surfaces in each case completely or partially along the connecting face. For example, a coated (aluminium) foil can be employed as the sealing means.
- It is particularly preferred if the sealing means is designed in each case in one piece or in multiple pieces at the connecting surfaces. Advantageously, the sealing means is designed in one piece, with a precise fit in conformity with the connecting surface. According to a further aspect, the sealing means is designed in multiple parts and can thus be disposed several times in succession in the direction of heat transfer, for example in the form of parallel strips.
- According to a preferred aspect, the sealing means comprises an adhesive, in particular an adhesive tape, a bonding agent, spray latex, or a combination thereof. The sealing means may hold the connecting surfaces together due to adhesion, thereby increasing the stability of the insulation container while reducing the passage of air to reduce heat exchange at the connecting surfaces.
- According to an advantageous aspect, the sealing means comprises a heat transfer minimizing material, particularly a thermal insulation material, a swelling tape, foam material, or a combination thereof. For example, the thermal insulation material is an insulation foam. The swelling tape may be made of a thermal insulation material and simultaneously minimize air passage at the connecting surfaces.
- It is particularly advantageous if the insulation container further comprises four side insulation elements, a bottom insulation element, and a lid insulation element. The four side insulation elements and the bottom insulation element are brought into abutment with each other along the respective connecting surfaces in such a way as to form a receiving space which is open on one side for receiving the temperature-sensitive products. The lid insulation element and the four side surface elements are brought into abutment with each other along the respective connecting surfaces in such a way as to completely cover the receiving space. A sealing means is disposed at and along, respectively, each connecting surface. In this manner, an insulation container in the form of a box can be improved.
- According to an alternative aspect, the insulation container further comprises four side insulation elements, a bottom insulation element, and a lid insulation element, wherein the four side insulation elements and the bottom insulation element are brought into abutment with each other along the respective connecting surfaces in such a way as to form a receiving space which is open on one side for receiving the temperature-sensitive products, wherein the lid insulation element and the four side surface elements are brought into abutment with each other along the respective connecting surfaces in such a way as to completely cover the receiving space, wherein a sealing means is disposed only on and/or along the connecting surface between the lid insulation element and the four side surface elements and/or the bottom insulation element and the four side surface elements. As a result of the sealing means disposed in this manner, when the lid of a box is closed, pressure can be applied to the boards from top to bottom such that the sealing means are squeezed or pressed together at the connecting surfaces so as to achieve an improved sealing efficiency.
- According to a preferred aspect, the vacuum insulation elements comprise a vacuum insulation panel. Thus, when multiple vacuum insulation panels are used in one insulation container, the connecting surfaces formed at the abutment joints can be sealed in an advantageous manner.
- It has proven to be a technically good alternative if the vacuum insulation panels of the vacuum insulation elements are each embodied as a single layer or as multiple layers. If several layers of vacuum insulation panels are used, adjacent connection abutment joints can also be sealed separately.
- Advantageously, the insulation container further comprises a sheathing which completely or partially surrounds the insulation container, the product or the vacuum insulation elements. For example, a sheathing made of foil prevents water vapor and air from reaching between the vacuum insulation elements.
- According to a preferred aspect, corner elements (edge protection elements) are disposed at the outer edges of the insulation container formed along the connecting surfaces. These corner elements are designed in such a way as to at least partially enclose the outer side of the vacuum insulation elements. In this way, the insulation container can be protected from impacts and associated damage caused to the products located in the insulation container.
- According to an advantageous aspect, at least one strap for stabilizing the vacuum insulation elements is disposed along the outer sides of the vacuum insulation elements. This allows the vacuum insulation elements to be held firmly together and, for example, due to the elasticity of the strap, contact pressure can be applied in such a way as to press the connecting surfaces together.

FIG. 2 shows an insulation container 1 according to the invention, which comprises fourside insulation elements 2, abottom insulation element 5 and a lid insulation element 6. The fourside insulation elements 2 and thebottom insulation element 5 are brought into abutment with each other along the respective connecting surfaces 7 in such a way that a receivingspace 3 which is open on one side for receiving the temperature-sensitive products (not shown) is created. The lid insulation element 6 is placed onto the connecting surfaces 7 of the fourside surface elements 2 in such a way that the receivingspace 3 is completely covered. A sealing means 4 is disposed at each of the connecting surfaces 7. -
FIG. 3 shows a side view of an insulation container 1 according to the invention which comprises avacuum insulation panel vacuum insulation panels vacuum insulation panels -
FIG. 3 also shows a complete sheathing 9 of an insulation container 1 according to the invention. This sheathing 9, for example, can be embodied as a foil, foil tube or foil bag. It is conceivable that this sheathing 9 is shrunk onto the insulation container 1 by means of thermal treatment. It is further conceivable that the sheathing 9 is embodied as an additional thermal pocket which completely or partially surrounds the product 1. Optionally, a thermal hood can be slipped over the insulation container 1 as a sheathing 9. -
