Description

Technical Field

[0001] The utility model relates to a protective shell for a flexible container, belonging to the technical field of transfer and storage of flexible containers. Background Art

[0002] In order to maintain the activity of liquid medicine and extend the storage time, the liquid medicine is often filled into a flexible container and stored frozen. At present, many enterprises in the market use a freeze-thaw machine for freezing; especially a horizontal freeze-thaw machine, whose freezing method is as follows: the plate layer is horizontally placed, the flexible container is horizontally placed above the lower plate layer, and the upper plate layer is closely attached to the upper surface of the flexible container; silicone oil circulates inside the plate layer, and by raising and lowering the temperature of the silicone oil, the freezing and thawing of the liquid medicine are realized. At present, in order to protect the liquid medicine and facilitate transfer, the flexible container is placed in a tray or a box; these two methods have the following disadvantages:

[0003] 1. When using a tray, the surface of the flexible container is relatively soft. When frozen, the surface of the flexible container may adhere to the plate layer, and it may be damaged during the material taking process;

[0004] 2. The flexible container is directly exposed outside, increasing the risk of damage;

[0005] 3. When using a box to place the product, there is a problem that it cannot be guaranteed that the upper surface of the product is in contact with the upper surface of the box during freezing. Summary of the Invention

[0006] The technical problem to be solved by the utility model is: to provide a protective shell for a flexible container.

[0007] To solve the above problems, the utility model provides the following technical solutions:

[0008] A protective shell for a flexible container, which includes an upper shell, a lower shell and a spring arranged between the upper shell and the lower shell. The spring is used to buffer the thickness of the product and provide a margin.

[0009] Preferably, fixing holes are respectively arranged at corresponding positions of the upper shell and the lower shell, and the fixing holes on the upper shell and the lower shell are connected by a cable tie to ensure that the distance between the upper and lower shells remains constant.

[0010] Preferably, the outer edges of the upper shell and the lower shell are connected by four evenly distributed springs.

[0011] Preferably, a fixing rod is inserted into the spring, and the lower end of the fixing rod is connected to the lower shell.

[0012] Preferably, the top end of the spring is in contact with the inner surface of the upper shell.

[0013] Preferably, the materials of the upper shell and the lower shell are 304 or 316 stainless steel.

[0014] Preferably, a handle is provided on the outer side of the lower housing.

[0015] Preferably, a temperature probe sleeve is provided inside the upper housing and the lower housing.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model can form an open space to protect the flexible container. The sealed container formed by the upper and lower housings avoids the direct contact between the flexible container and the laminar, and at the same time reduces the risk of damage. Description of the Drawings

[0017] Figure 1 is a schematic structural view of the flexible container protection shell provided by the present utility model;

[0018] Figure 2 is a schematic view when the present utility model is in use. Detailed Embodiments

[0019] To make the present utility model more obvious and understandable, preferred embodiments are provided below in conjunction with the drawings for detailed description as follows.

[0020] Embodiment

[0021] As Figure 1 shown, a flexible container protection shell provided by the present utility model includes an upper housing 1, a lower housing 4, and a spring 3 disposed between the upper housing 1 and the lower housing 4. The outer edges of the upper housing 1 and the lower housing 4 are connected by four evenly distributed springs 3. A fixing rod 2 is inserted through the spring 3, and the lower end of the fixing rod 2 is connected to the lower housing 4. The length of the fixing rod 2 is preferably within the compression range of the spring 3. The top end of the spring 3 is in contact with the inner surface of the upper housing 1.

[0022] Corresponding fixing holes 1-1 and 4-1 are respectively provided on the upper housing 1 and the lower housing 4. The fixing holes on the upper housing 1 and the lower housing 4 are connected by a cable tie to ensure that the distance between the upper and lower housings remains constant.

[0023] The materials of the upper housing 1 and the lower housing 4 are 304 or 316 stainless steel.

[0024] A handle 4-3 is provided on the outer side of the lower housing 4.

[0025] A temperature probe sleeve 1-2 is provided inside the upper housing 1 and the lower housing 4.

[0026] Put the flexible container 7 into the above flexible container protection shell, as Figure 2As shown, an upper heat exchange plate (5) and a lower heat exchange plate (6) can be respectively placed on the top and bottom of the flexible container protective shell to exchange heat with the product, that is, transfer the cold in the plate layer to the product inside the flexible container to achieve freezing, or transfer the heat in the plate layer to the product in the flexible container to achieve thawing.
