Embodiment Construction

[0028] figure 1 An embodiment of an assembly according to an aspect of the invention is shown, comprising

[0029] - pipe head 1,

[0030] - Cap 2, and

[0031] - Removable spacer ring 3.

[0032] Tube head 1 comprises a neck 11 defining a longitudinal axis Z-Z, a shoulder 12 and a solid insert 13 formed as a cap closing said neck 11 .

[0033] More precisely, insert 13 comprises a peripheral portion 16 , typically frusto-conical or disc-shaped, and a central portion 17 , the diameter of which typically corresponds to the internal diameter of neck 11 , forming said cap.

[0034] The neck 11 comprises on its outer circumference a thread 14 adapted to enable the cap 2 to be screwed onto the neck 11 .

[0035] The cap 2 comprises an internally tapped thread 21 adapted to cooperate with the thread 14 of the neck 11 , and a punch 22 configured to be inserted into the neck 11 of the tube head 1 when the cap 2 is screwed onto said neck 11 . The longitudinal direction of the cap ...

Abstract

A tube head assembly includes a tube head that includes a lid, a cap that includes a punch and a spacing ring. The ring is dimensioned in such a way as to keep the punch spaced from the lid when the cap is screwed onto the neck. Further, the ring and the cap include lugs and recesses co-operating in such a way as to limit their rotation relative to one another in the direction of screwing of the cap onto the neck.

Description

technical field [0001] The invention relates to the field of flexible pipes comprising a cap closing the neck before the pipe is used for the first time, and a piercing cap adapted to pierce the cap. Background technique [0002] Tubes are known which are equipped with a cap associated with a piercing cap comprising a punch adapted to perforate the cap when the cap is inserted into the neck of the tube in a first direction and when the cap is inserted in a second direction The cap is screwed onto the neck while the orientation is positioned onto the neck of the tube. [0003] In fact, the cap keeps the product contained in the tube sealed during storage before the first use of the product, said cap being a very important component throughout the lifetime of the tube. [0004] However, these solutions are not very practical and are not valued by users. These solutions also result in a tube with a punch protruding from the cap of the tube during use and storage, and a thrust...
