The concentrate glass jar container, also called as pressed glass jars, if we observe carefully we will find the inner wall of the jar is straight up and down, there is no curved part on the inner neck part, but you can find there is a stage inside the mouth of press-and-blow molding glass jar.
Different manufacturing process
Pressing glass container, is to install a mold and a punch on the glass forming machine, inject the liquid glass into the mold and press the liquid glass by using the punch to make the glass into the shape required by the mold.
Blown glass container, which is made by Press & Blow Process. It can be blown into a glass container with a jar/bottle diameter larger than the mouth diameter.
In simple terms, the glass cosmetic jars with stage inside are blown glass jars, and those jars with straight inner wall (from the mouth till the base) are concentrate glass jar containers (or pressed glass jars).
The shape of this two styles of glass cosmetic container can be round, square or other customized shapes.
