Air comes out when you squeeze with that design - it’s a poor closure.
so you mean air shouldnt be able to come out of the bottle when you squeeze the bottle?
they said this is normal for caps that are not air tight and everyone is using it and no one has any complain and i shoud use Air and water-tight caps which are screw caps if i dont want air to come out.
this was a local cap producer and local producers here usually has lower quality products but cheaper. i am already looking to import high quality caps from another country.
what about the products that i have sold with caps that have this problem?
is ther any risk of microbes getting in or preservative (formalin) escap from bottle or something bad happen to product? not all the caps are like this. this only happens to some of them.
if we squeeze the bottle, fragrance scented air comes out. if we dont squeeze the bottle there is no scent even in warehouse where hundreds of these bottles are stored.( looks like if we dont sqeeze the bottle, air is not comming out easily).
