The sample mount arrangement defines a sampling channel and the port housing defines a sampling opening and a first securing mount. The lid assembly includes a latch arrangement and defines a second securing mount.

An object of the present invention is to provide a container for cryopreservation and transportation which is excellent in maintainability and can appropriately control the temperature of an object to be frozen. The present invention provides a container for cryopreservation and transportation (1A) used to transport an object to be frozen, including: a thermal insulation container (2) having an upper opening (2a); a thermal insulation lid (3) which closes the upper opening (2a) of the thermal insulation container (2); and a cooling unit (4) which is held in the thermal insulation container (2) while absorbing liquid nitrogen, wherein a housing space (K) for accommodating a storage tool (50) for storing the object to be frozen is provided inside the thermal insulation container (2), and the cooling unit (4) is detachable through the upper opening (2a) of the thermal insulation container (2) while the storage tool (50) located in the housing space (K) is housed in the thermal insulation container (2).

The invention relates to a box for preservation under vacuum. The box incudes a container and a lid for closing the container. The container includes a body with an internal wall and an external wall, the internal wall delimiting an internal volume of the container, the internal volume being upwardly open when the container is placed on a horizontal surface. The internal wall and external wall are connected together at an edge and define a first cavity between them, the edge having a closed contour. The lid includes a body with a perimeter that has a closed contour and is intended to bear in a sealing manner against the edge of the container when the cover is fitted on the container in a closed configuration of the box. The first cavity opens towards the exterior environment through at least one opening.

A portable, handheld, storage device for holding and organizing perishable goods. The storage device includes an upper assembly having a cap connected to a working lid, a main body having a removable insert that can hold perishable goods in the removable insert or within the interior cavity of the main body. The main body is connected to a lower assembly that includes a removable thermal pack and thermal conductor rod. The thermal conductor rod conducts heat through the main body by making contact with an exterior underside of the main body to provide a suitable temperature within an interior of the main body or the removable insert. A removable pack is freezable or can be heated to provide a desired temperature as conducted from a bottom cup holding the removable pack to the interior of the main body and the items stored inside the main body or the removable insert.

A liquid nitrogen tank includes a tank, a storage rack and a drive component. The tank includes a tank cover, a tank body, a vacuum cavity layer and a heat-insulating cavity layer. The tank cover is disposed to cover on the tank body. An access door is provided on the tank body. A storage cavity is provided in the tank body. The heat-insulating cavity layer is provided on a periphery of the storage cavity. The vacuum cavity layer is provided on a periphery of the heat-insulating cavity layer. The storage rack is provided in the storage cavity. A plurality of cryopreservation tube racks are stored in the storage rack. The drive component can drive the storage rack to rotate and move up and down in the storage cavity, and can drive the plurality of cryopreservation tube racks to move to a position corresponding to the access door.

An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The second outer wall can include a second end configured to support the container on a surface. The second outer wall can include a dimple, and the dimple can include a circular base and an inner portion converging to an hole extending into the second outer wall. The hole can be sealed by a resin, and the circular base can be covered by disc formed of the material. Alternatively, a cap can cover the dimple, and a weld can connect the cap to the second outer wall. The container can also include a sealed vacuum cavity forming an insulated double-wall structure between the first inner wall and the second outer wall.

A portable insulating device kit may be configured to fit within a smaller container for easier shipment. In one example, the assembly may include a base, a top wall having an opening, an inner liner configured to extend into the opening of the top wall to form an interior cavity defining a volumetric storage capacity and an exterior wall. The container can have a flat configuration defining a length, height, and width. The base, the top wall, the inner liner, and the exterior wall may be configured to be assembled into a portable insulating device. The volume of the container may be less than the volumetric storage capacity of the assembled portable insulating device, and the base, the inner liner, and the exterior wall are configured to be detached from one another and shipped in the container.

The present invention provides a disposable insulator for a cup. The disposable insulator includes a sleeve including an insulating material to provide thermal insulation to the exterior of the cup, the sleeve having a top edge, a bottom edge, an inner surface, and an outer surface having a thickness therebetween, the sleeve being tapered from the top edge to the bottom edge and configured to surround at least a portion of the cup, and at least one finger pad made of the insulating material having a bottom edge, the finger pad being separable from the remainder of the sleeve and movable from a first position to a second position, in the first position, the bottom edge of the finger pad being proximate to the bottom edge of the sleeve, and in the second position, the finger pad being separated from at least a portion of the remainder of the sleeve and movable relative to the remainder of the sleeve, in the second position the finger pad being foldable relative to the sleeve with the bottom edge of the finger pad positionable proximate to the top edge of the sleeve, wherein, when in the second position, the folding of the finger pad increases the thickness of the insulation material present at the finger pad to create an area of increased insulation on the sleeve to provide additional thermal insulation to a portion of the exterior of the cup.
