摘要： An easily openable container lid includes a shell and liner. The shell includes a flat circular top wall, a skirt wall having an arcuate part extending arcuately radially outward and downward from the peripheral edge of the top wall in a longitudinal cross sectional view and a linear part extending vertically downward following the arcuate part, and a grip piece extending from the lower end of the skirt wall. The top wall, the skirt wall and at least a base part of the grip piece are integrally formed of a metal sheet, and a pair of scores each composed of first and second portions are formed on the shell. The first portions extend on the skirt wall upward from both sides of the grip piece, and the second portions extend arcuately between the upper end part of the skirt part and the peripheral edge part of the top wall.

摘要： An oxygen-shielding container lid according to the present invention comprises a high density polyethylene cap shell 1 having a skirt section 7 and a top plate section 5 provided with an inner ring 9 for intimate contact with an inner surface of a container mouth; and an in-shell molded body 3 provided in a portion of an inner surface of the top plate section which is surrounded with the inner ring 9. The in-shell molded body 3 is composed of a primary molded body 3a which has been formed by in-shell molding on the inner surface of the top plate section and which has an oxygen shielding function; and a secondary molded body 3b which has been formed on the primary molded body 3a by in-shell molding so as to cover the primary molded body 3a and to be fused and fixed to the inner surface of the top plate section at the peripheral edge of the primary molded body. A resin composition used for formation of the secondary molded body 3b contains linear low density polyethylene, and has a melt flow rate at 190° C. of 1 to 10 g/10 minutes, a density of 0.900 to 0.920 g/cm3, and a nominal tensile strain at break, as defined by JIS K-6922-2, of 400% or more.

摘要： A container lid is configured such that repeated movement of a grip piece and a connecting piece of the lid will not break the connecting piece so that the lid can be removed easily. An extension section extends upwardly from an upper end of the connecting section along an inner peripheral surface of a skirt wall of the lid. When the container lid is on the mouth-neck section of a container, an upper end part of the extension section is sandwiched between an inner peripheral surface of the lid skirt wall and an outer peripheral surface of a locking projection on the container mouth-neck section.

摘要： To provide a cap and a capped container that prevent a user from feeling a sense of discomfort about a torque when the cap is opened while reliably preventing the inversion of a flap when the cap is opened. Provided is a cap (10) having a TE band (30), with this TE band (30) having a flap (32), the flap (32) has a flange engaging part (32b) and an attitude maintaining piece (32c), and an inner peripheral wall of the band body part (31) has a release part (22c) that forms a gap between an outer peripheral wall of the attitude maintaining piece (32c) and the inner peripheral wall of the band body part (31) when the cap is attached to the container. A circumferential width of the attitude maintaining piece (32c) is formed to be narrower than a circumferential width of a flap body (32a).

摘要： A cap-type synthetic resin container lid (2), which can be removed sufficiently easily from a mouth-neck section (38) of a container without requiring great force and, even after removal from the mouth-neck section (38) of the container, continues to be kept integral without being partly separated to form a scrap piece, is provided.The container lid (2) includes thin-walled inversion pieces (18) arranged at intervals in the circumferential direction and extending upward beyond a top panel wall (4) from the lower ends of the thin-walled inversion pieces, the lower ends being connected to the outer peripheral surface of a skirt wall (6) or to the boundary part between the outer peripheral surface of the skirt wall (6) and the upper surface of the top panel wall (4); a restraint wall (20) connected to the upper ends of the thin-walled inversion pieces (18) and having a specific site (22) in the circumferential direction, the specific site being either split, or being defined by a breakable weakened section (24); and an operating section (30) connected to the outer peripheral surface of the skirt wall (6) via a connecting piece (28) extending out radially from the outer peripheral surface of the skirt wall (6) at a position in alignment with the specific site (22). Locked projections (26) and locking projections (36) are disposed in the restraint wall (20) and the connecting piece (28), respectively, to collaborate in restricting the expansion of the restraint wall (20).

摘要： A composite container lid which includes an inner cap fitted onto the container mouth portion by screw engagement, an over-cap fitted onto the inner cap, and an IC tag. The over-cap has a top panel and a skirt descending from the circumferential edge of the top panel. The inner cap has a top plate and a cylindrical wall descending from the circumferential edge of the top plate and has a thread formed in the inner surface thereof to come into screw engagement with the outer surface of the container mouth portion. An engaging means is provided between the inner surface of the skirt of the over-cap and the outer surface of the cylindrical wall of the inner cap to transmit the turn of the over-cap fitted onto the inner cap to the inner cap.

摘要： A synthetic resin container closure does not render required initial torque and required secondary torque for unsealing excessively high, and but can fully reliably prevent slipping-out, a phenomenon where a locking device ascends while elastically climbing over a locking jaw portion, without causing breakage of a circumferential breakable line, at the time of unsealing. Such a synthetic resin container closure and a combination of the synthetic resin container closure and a container are provided. An inverted truncated cone-shaped fitting surface extending upwards at a radially outward incline from the base edge of an upper surface of the locking device is disposed in the inner peripheral surface of a tamper evident bottom section demarcated below the circumferential breakable line formed in a skirt wall.

摘要： A synthetic-resin container lid having tamper-evident characteristics, which is not separated in its entirety from a mouth-neck portion of a container even after the mouth-neck portion of the container is unsealed, is manufactured rapidly and inexpensively. A plurality of scores (26, 30, 32, 34, 36, 38) are formed, as post-processing, at predetermined positions in an incomplete container lid formed with no scores.

摘要： A plastic cap is able to be applied to a container having a screw formed with a vent. The plastic cap has an outer ring for sealing at least the outer surface of the mouth of the container, and an inner ring for sealing the inner surface of the container mouth. In a closed state, sealability is maintained by a seal point on the inner surface of the outer ring. In an unsealing step, a seal point on the outer surface of the inner ring is shifted into a pressure-contacted state on the inner surface of the container mouth, where there is no risk of sink marks caused by molding strain, before a seal by the outer ring is released. Thus, reliable sealability can be exhibited even when the cap is applied to a container having inferior dimensional accuracy.

摘要： A container lid (2) can be removed from a mouth-neck section (106) of a container without the need for a tool. Following the breakage of a breakable thin-walled line (70) in a transition region (52), the breakage of a breakable thin-walled connection wall (68) in a side wall separation region (54) can be started sufficiently smoothly in the container lid (2). For this purpose, the breakable thin-walled line (70) formed in a side wall (10) in the transition region (52) is brought into a form in which at least a part thereof extends obliquely downwardly in a counterclockwise direction.
