This shape is conducive to the cutting to lid by drift, and previous embodiment is by the cutting of compressing to provide drift.

The shoulder 12 of tube head 1 comprises the teat 15 of radially giving prominence to from the junction between neck 11 and shoulder 12.

Spacer ring 3 is equipped with such as the device that is suitable for the internal-rib 32 coordinating with described teat 15, so that ring can only rotate around neck 11 in a direction along axis Z-Z, this direction screws to the direction on neck 11 corresponding to cap 2, the direction that teat 15 coordinates with rib 32 to avoid spacer ring 3 to outward winding from the neck 11 of tube head 1 at cap 2, rotates around neck 11.

Fig. 3 shows the embodiment of the embodiment that comprises teat 15, and described teat has around the cardinal principle of axis Z-Z spiral-shaped.

Multiple embodiments are possible; Teat 15 can for example form the circular arc extending from neck 11 center, substantially spiral-shaped to form, also or substantially gear shape.

First between used life, user is from neck 11 cap 2 of outwarding winding.Coordinate to stop the rotation of spacer ring 3 with rear protrusion 15 and internal-rib 32.

Thereby spacer ring 3 remains motionless in the time that cap 2 is outwarded winding, this causes the disengaging with respect to cap 2 of the fracture of material bridge 31 and spacer ring 3.

Once cap 2 is outwarded winding and is removed from neck 11, user is by making spacer ring 3 slide and remove spacer ring 3 along neck 11, and then cap 2 is screwed to neck 11, until cap 2 touches to neck 11 or shoulder 12, this has caused the drift 22 of the cover cap 2 being formed by inserts 13 pars intermedias 17 cut or bore a hole, and the free end 23 of the drift 22 of described cap 2 is through the central part 17 of inserts 13.

Advantageously local to the cutting of lid, be connected with the remainder of inserts 13 with the one or more parts that have been cut that make lid, thereby avoid the material that forms inserts 13 to mix with any of product who is contained in respective tube, and avoid may be by this Distribution of materials to user.

For instance, with regard to cutting the cuttings of 360 degree that are lid completely, that is to say, the annular of advantageously having carried out being completed by the rotation of cap 2 is cut---the cutting between a kind of 250 degree and 330 degree, thereby form connection fully to ensure cut central part 17 and the linking of peripheral part 16.

In industrial scale, dress cap, namely cap 2 screws to the step on neck 11 and is typically carried out by dress cap machine.But, need construct a kind of machine that so that it screws cap 2 to neck 11 spacer ring 3 touches to the exact location of shoulder 12 and protective material bridge 31 simultaneously exquisitely.Really,, if cap 2 is a little bigger a little to the rotation on neck 11 in order to screw cap, material bridge 31 ruptures, and cap 2 separates from spacer ring 3.

For fear of the risk that material bridge 31 ruptures during dress cap, spacer ring 3 and cap 2 comprise lug 34 and recess 35, described lug and recess fit in the rotation that limits the direction that they relative to each other screw on neck 11 along cap 2, with avoid encircling during cap 2 is screwed on neck 11 3 and cap 2 between described material bridge fracture.

Lug 34 and recess 35 are configured such that they are only for hatting 2 and spacer ring 3 along the relatively rotating of direction (be generally clockwise direction and represented by the arrow in Fig. 4) corresponding to cap 2 being torqued-up to neck 11, wherein, cap 2 and spacer ring 3 be along being possible corresponding to the relatively rotating of direction (being generally anticlockwise direction) of the cap 2 of outwarding winding from neck 11, and described in relatively rotate and make user can break material bridge 31 to separate cap 2 and spacer ring 3.

Lug 34 typically extends in the plane of the axis Z-Z perpendicular to neck 11.

Can in Fig. 4, see, because lug 34 separates with recess 35, due to the interval 36 between lug 34 and recess 35, relatively rotating between cap 2 and spacer ring 3 is possible.

The size at the interval 36 between lug 34 and recess 35 according to form cap 2 and spacer ring 3 material mechanical specialities and particularly determine according to its elasticity and plastic deformation characteristic, to make relatively rotating between cap 2 and ring 3 cause the distortion of material bridge 31 to be less than its fracture resistance.According to specific implementations, interval 36 equals 0.5mm, thereby is not having

cap

2 and 3 distortion in the situation thats of ring consistent with the distance between lug 34 and recess 35.

Thereby the present invention allows to guarantee the preservation of the material bridge 31 of attachment cap 2 and spacer ring 3 during dress cap, thereby the interval function producing due to ring allows to guarantee to preserve before using first lid, and described ring allows to maintain interval between the drift 22 of cap 2 and the lid of tube head 1.

In addition, the present invention allows to guarantee to open proof function.Really,, first between used life, user is from neck 11 cap 2 of outwarding winding; Coordinate to stop the rotation of spacer ring 3 with rear protrusion 15 and internal-rib 32.

Spacer ring 3 keeps motionless in the time that cap 2 is outwarded winding subsequently, and this causes fracture and ring 3 separation with respect to cap 2 of material bridge 31, thereby allows to identify simply by used pipe.
