AI Technical Summary
The traditional freeze-dryer pressing bottle plug device lacks a fixing mechanism to the bottle body, which causes the freeze-drying bottle to tip over when pressed, affecting normal use. Moreover, due to the differences in bottle specifications, materials and tightness of the bottle, it is easy to cause the pharmaceutical bottle to be crushed, exploded or blocked in place.
A freeze-dryer pressing bottle plug device is designed, including a placement box, a support column, a limiting plate, a placement hole, a vertical plate, a sliding column, a clamping block, a retaining ring and a first spring. Through the combination of these components, the clamping and fixing of the freeze-drying bottle is achieved to prevent pouring, and the movement distance of the pressure plate is adjusted through the buffer device to prevent the bottle from being pressed and exploded.
It effectively prevents the problem of pouring during pressing of the freeze-dried bottle, and adjusts the height of the buffer device to avoid the compression of the freeze-dried bottle, ensuring the effective sealing of the bottle stopper and the quality of the medicine.

Abstract
Description
Technical Field

[0002] A freeze dryer is a vacuum freeze dryer that uses the space in the box to freeze-dry the materials placed in the box in a vacuum manner. A bottle stopper pressing device is a device used to seal freeze-dried bottles. One of its main functions is to apply pressure on the mouth of the freeze-dried bottle to seal the bottle stopper at the bottle mouth to prevent air, moisture or other contaminants from entering the bottle and affecting the freeze-drying process and product quality. However, most traditional bottle stopper pressing devices do not have a mechanism to fix the bottle body.
