Description

Technical Field

[0001] This utility model relates to freeze-drying tubes, and more particularly to a freeze-drying tube cap and a freeze-drying manifold. Background Technology

[0002] Freeze-dried bulbs are generally packaged inside freeze-drying tubes. For information on the existing structure of freeze-drying tubes, please refer to the Chinese patent publication CN114100721A entitled "A Freeze-Drying Tube and a Multi-Unit Freeze-Drying Tube". When freeze-dried bulbs are transported in such freeze-drying tubes, static electricity is generated during transportation. During use, the freeze-dried bulbs often flip or become upside down and adhere to the tube, which prevents the freeze-dried bulbs from thawing quickly. It is necessary to manually flick the tube to make the freeze-dried bulbs upright, which not only results in low thawing efficiency but also makes the process time-consuming and laborious. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a freeze-drying tube cap and freeze-drying manifold that facilitates freeze-drying and capping and can prevent freeze-dried bulbs from flipping or shifting, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A freeze-drying tube cap includes a cap body, on which a downwardly extending cylindrical portion and a support column are provided. The support column is located inside the cylindrical portion and its length is greater than that of the cylindrical portion. An upper sealing ring and a lower sealing ring are provided on the outer wall of the cylindrical portion. A vertically extending evaporation window is opened on the side of the cylindrical portion, and the upper edge of the evaporation window is located between the upper sealing ring and the lower sealing ring.

[0006] Preferably, the support column is coaxially arranged with the cylindrical portion.

[0007] Preferably, the evaporation window extends downward to the lower edge of the cylindrical portion.

[0008] Preferably, the cover is a flat cover.

[0009] Preferably, the outer wall of the support column is formed with a raised ridge.

[0010] Preferably, the outer side wall of the support column has three protruding ridges evenly distributed.

[0011] A freeze-dried manifold includes multiple tube bodies and multiple freeze-dried tube caps, with the cylindrical portion inserted into the tube body and the upper sealing ring and the lower sealing ring sealingly engaged with the tube body.

[0012] Preferably, the caps of multiple freeze-drying tubes are connected in sequence, and the multiple caps are integrally formed.

[0013] Preferably, a hollow connecting part is provided between two adjacent covers.

[0014] In the freeze-drying tubing disclosed in this utility model, the cylindrical part and the support column are integrally formed with the cover. The tubing is placed in a pre-set freeze dryer. After the freeze-dried bulbs are loaded into the tubing, the cylindrical part is aligned and inserted into the tubing, so that the lower sealing ring fits tightly with the tube wall, while the upper sealing ring is placed above the tube. At this time, the upper half of the evaporation window is exposed. During the drying process, the moisture inside the tube evaporates through the evaporation window. After freeze-drying is completed, the capping mechanism in the freeze dryer applies pressure to the cover, pressing the cylindrical part and the support column into the tubing, and making the upper sealing ring fit tightly with the tube wall. The freeze-drying and capping efficiency is higher. At the same time, the support column's restraining effect on the freeze-dried bulbs effectively prevents the freeze-dried bulbs from turning over or shifting during transportation, thus facilitating thawing and use.

[0018] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0019] This utility model discloses a freeze-drying manifold, combined with Figures 1 to 3 As shown, it includes multiple tubes 8 and multiple... Figure 1 The freeze-drying tube cap shown is described. The freeze-drying tube cap includes a cap body 1, on which a downwardly extending cylindrical portion 2 and a support column 3 are provided. The support column 3 is located inside the cylindrical portion 2, and its length is greater than the length of the cylindrical portion 2. An upper sealing ring 4 and a lower sealing ring 5 are provided on the outer wall of the cylindrical portion 2. A vertically extending evaporation window 6 is opened on the side of the cylindrical portion 2, with its upper edge located between the upper sealing ring 4 and the lower sealing ring 5. The cylindrical portion 2 is inserted into the tube body 8, and the upper sealing ring 4 and the lower sealing ring 5 are in a sealing fit with the tube body 8.

[0020] In the above structure, the cylindrical part 2 and the support column 3 are integrally formed with the cover 1. The tube 8 is placed in a preset freeze dryer. After the freeze-dried bulb is loaded into the tube 8, the cylindrical part 2 is aligned and inserted into the tube 8, so that the lower sealing ring 5 fits tightly with the tube wall of the tube 8, while the upper sealing ring 4 is placed above the tube 8. At this time, the upper half of the evaporation window 6 is exposed. During the drying process, the moisture in the tube evaporates through the evaporation window 6. After the freeze-drying is completed, the capping mechanism in the freeze dryer applies pressure to the cover 1, pressing the cylindrical part 2 and the support column 3 into the tube 8, and making the upper sealing ring 4 fit tightly with the tube wall of the tube 8. The freeze-drying and capping efficiency is higher. At the same time, the support column 3 restricts the freeze-dried bulb, which effectively prevents the freeze-dried bulb from turning over or shifting during transportation, thus facilitating thawing and use.

[0021] As a preferred embodiment, the support column 3 is coaxially arranged with the cylindrical portion 2. In practical applications, the cylindrical portion 2, the support column 3, and the cover 1 can be manufactured by injection molding.

[0022] In this embodiment, the lower end of the evaporation window 6 has an opening, combined with Figure 1 and Figure 2 As shown, the evaporation window 6 extends downward to the lower edge of the cylindrical portion 2.

[0023] To prevent the freeze-dried bulbs from getting stuck in the gap between the support column 3 and the tube wall, in this embodiment, the outer side wall of the support column 3 is provided with a raised ridge 7. Specifically, three raised ridges 7 are evenly distributed on the outer side wall of the support column 3.

[0024] To improve evaporation efficiency, in this embodiment, two symmetrical evaporation windows 6 are provided on the side of the cylindrical part 2.

[0025] In this embodiment, the cover 1 is a flat cover. Multiple freeze-drying caps are connected sequentially, and the multiple cover 1s are integrally formed. Furthermore, a hollow connecting portion 9 is provided between two adjacent cover 1s. This hollow connecting portion 9 effectively increases the connection elasticity between two adjacent cover 1s.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
