In this case, the outstanding section 32 of the outward flange 29 of sealing band 27 has formed with the recessed section 37 of the inward flange 28 of sealing band 27 the fracture initiation region 31 that is roughly chevron pointing (or inverted V-shaped) here jointly.
These two sections 32 and 37 are complimentary to one another; They are parallel or extension at least substantially in parallel relative to each other.
This specific structure is intended to avoid occurring in these 31 places, fracture initiation region the local widening of sealing band 27, and this is widened can increase the needed power of opening inherently.
In context, the path 18 of flange 13 and pulling-on piece 23 are relatively arranged in (between the inward flange 28 in sealing band 27 and outward flange 29) overlay area 30 of sealing band 27.
More specifically, this path 18 is here arranged in the overlay area between its exterior section 32 and interior section 37 in fracture initiation region 31.
In the situation that there is path 18, this fracture initiation region 31 is here for eliminating to a certain extent possible the widening (sealing band this widen the weakening that can be used for compensating contingent bed knife) of sealing band 27.
In addition, the aperture 181 of path 18 is arranged to about the axis 32' in fracture initiation region 31 and longitudinal axis 23'(Fig. 3 and 4 of pulling-on piece 23) symmetrical or at least roughly symmetrical.
As a rule, this fracture initiation region 31 of sealing band 27 can be arranged on a kind of like this container 3, and (one or additional) flange 13 of this container 3 can not arrange any above-mentioned path 18.
On the other hand, flange 13 advantageously has variable width, the section 13'(Fig. 3 of portion widening) in path 18 places, and depend on the circumstances, this section 13' of portion widening is in 31 places, fracture initiation region, to contribute to its layout.
