CONTAINER NECK AND METHOD FOR MAKING SAME, AND CONTAINER WITH ASSEMBLING METHOD AND DEVICE

摘要

The invention concerns a container neck (3) obtained from a synthetic material sheet by thermoforming process. Said container neck (3) is characterised in that said sheet has a given nominal thickness (e), the wall forming the neck (3) has the same thickness without noticeable thinning over its entire useful length, that is over its inner surface height against which is to be located a plug (26) of a particular type engaged in the neck (3) when the container is closed. The invention also concerns a method for making said container neck (3) and a container (20) with its assembling method and the device for implementing the method. The invention is useful for packaging products capable of being extracted from the container by successive withdrawals, involving plugging and unplugging several times, provided that the successive plugging operations ensure that the container remains sealed.
