Fig. 9 to Figure 11 shows the former 201 according to another alternate embodiment, with the class of former 101 shown in Fig. 5 to Fig. 8 Seemingly, from the embodiment, the difference of former 201 essentially consists in the molded surface being separately positioned on panel element and ring is formed The construction of profiled surface on type element.

Especially, former 201 includes annular shaped element 204, and it, which is provided with, is configured to make to be formed at forming cavity 3 in outside The profiled surface 209 of side wall (tamper ring may the be provided with) shaping of interior spill object.Former 201 further comprises being provided with The panel element 205 of molded surface 206, molded surface 206 is configured not only to make the transverse wall of spill object to be shaped in outside, and The join domain for being used in connection transverse wall and side wall shapes in outside.

In the embodiment shown in Fig. 1 to Fig. 8, the side wall of spill object, and the company for connecting side wall and transverse wall Region is connect, is changed to shape by annular shaped element in outside, and the purpose of panel element is, only makes the transverse wall of spill object In outside shaping.

Therefore, molded surface 206 includes essentially flat central member, and it is suitable to shape transverse wall, central member Surrounded by bending coupling part, bending coupling part is adapted in use to the join domain of the side wall and transverse wall in connection spill object Shaping.

Molded surface 206 limits the boundary of the groove for the thickness for entering panel element 205.

Reference surface 7 surrounds molded surface 206.Groove 38 can be formed on reference surface 7, the purpose of groove 38 is to hold Receive seal washer 39.

Recessed annular region 247 can be set on reference surface 7, and its shape is also configured as being groove.By annular region 247 are arranged in concentric position relative to groove 38, also, annular region 247 than groove 38 closer to molded surface 206.Ring Shape region 247 is used as being used for the air vent of any air stayed in forming cavity 3 in moulding process.Moreover, being attributed to annulus Domain 247, prevents any grease or other similar materials for mounting gasket 39 from reaching forming cavity 3.

Former 201 similar mode assembling and operation in the way of with reference Fig. 5 to Fig. 8 descriptions before.In addition, former 201 allow to obtain by reference to advantage disclosed in the embodiment of disclosed mould before.
