AI Technical Summary

Technical Problem

Existing lyophilized formulation packaging bottles have problems such as protruding bypasses affecting aesthetics, limited manufacturing methods and high costs, and potential liquid residue and leakage.

Method used

A notch is made in the packaging bottle and a flexible part is set. The flexible part deforms under the pressure of the liquid formulation to form a bypass, realizing the mixing of liquid and solid formulations. It is operated by an injection holder and push rod and can be used with multiple packaging bottles.

Benefits of technology

It improves the aesthetics of the packaging bottle, reduces manufacturing costs, avoids liquid residue and leakage, and facilitates mixing.

Abstract

The utility model relates to the technical field of freeze-dried preparation product packaging, specifically relates to a kind of packing bottle and packing assembly, the packing bottle includes bottle body, in initial state, the first piston in bottle body and the discharge port of bottle body form solid preparation cavity between, the second piston in bottle body and the first piston form liquid preparation cavity between;The side wall of bottle body is formed with gap corresponding solid preparation cavity, and flexible piece is sealingly arranged at gap;When the first piston is moved to liquid preparation and flexible piece contact under the pressure action of second piston and liquid preparation, liquid preparation can extrude flexible piece to make flexible piece produce elastic deformation and form bypass outside, and liquid preparation can flow from bypass to the first piston and the discharge port of bottle body between and solid preparation mix. The packing bottle provided by the utility model, by setting flexible piece by opening gap on bottle body, so that product can be more beautiful, cost can be reduced, and there is no waste and leakage problem of liquid.
