CAN CONTAINER
Document Type and Number:
WIPO Patent Application WO/2007/122724
Kind Code:
A1
Abstract:
A resealable can container with a can body consisting of a welded can barrel that
without degrading of productivity and unsealability, satisfactorily ensures
the tight seal between curled portion of its neck part and resin-made liner of
its cap. In can body (2) consisting of a welded can barrel resulting from overlapping
and welding of ends of a metal sheet material rolled into a cylindrical configuration,
the step by welded portion (2a) on the surface of curled portion (21a) brought
into contact with resin-made liner (37) of cap (3) is rendered smaller than the
step by welded portion (2a) on barrel part (22), and regulated so as to fall within
the range of 15 to 100 μm. In the cap (3) with resin-made liner (37) for sealing,
the hardness of the resin-made liner (37) is regulated so as to fall within the
range of HDA 30 to HDA 70 in terms of durometer hardness in accordance with ISO 868
(JIS-K 7215).
