摘要:
A plastic cap of this invention is opened by tearing-off and is comprising a top plate (1) provided with a sealing portion to be engaged with the mouth of a container, a skirt (2) extending perpendicularly from the top plate, and a tear-off portion (3) arranged around the skirt and defining an upper closure portion for resealing and a lower opening band, wherein in the inner surface of the skirt, at an upper position than the tear-off portion, a diametrically inwardly-directed protrusion which is engaged with a jaw of the container is formed peripherally intermittently, simultaneously, at a lower position than the tear-off portion, a flap piece (7) whose tip portion (71) is engaged with the jaw of the bottle is formed peripherally intermittently, and the engaged protrusion (6) and the flap piece are formed at least alternately in most of the peripheral direction. The plastic cap has excellent sealing reliability, easy openability, and tamper-evident property while the cap height is lowered and the resin weight of the resin is reduced.

A metallic container closure comprising a shell of a thin metal sheet having a circular top panel wall 7 and a skirt wall 9, and a synthetic resin liner arranged in the shell, the skirt wall 9 having a thread-forming region and an annular groove 17 positioned at an upper end portion of the thread-forming region, wherein an internal pressure release line ,4 extending in the circumferential direction is arranged in the skirt wall 9 at a portion over the annular groove 1 , and annular bead 30 is arranged so as to pass through between the internal pressure release line A and the annular groove 17. The metallic container closure effectively releases the gas when the pressure in the container is elevated and effectively prevents the skirt wall from being deformed at a portion where the internal pressure release line A is formed when it is being wrap-seamed with the mouth-and-neck portion of the container.

A cap comprises a cap body (2) fitted and secured to the mouth of a container, an upper closure (3) provided in the cap body, and a ring-like member (4) which covers the outer surface of a skirt portion (6) of the cap body (2). The ring-like member (4) and the skirt portion (6) are coupled together through breakable bridge portions (17). These two members are separated away from each other via cut surfaces (19) but are intimately contacted to each other at the cut surfaces (19). The cap can be easily removed by hand from the mouth of the container, and can be separated from the container at the time of disposal.
摘要:
A container cap which offers improved opening/closing performance and improved touch feeling. Linear protuberances are formed on the circumferential wall of the main portion of the skirt of the container cap of the container. The protuberances include large protuberances having a large height and small protuberances having heights of protrusion from the outer surface of the circumferential wall portion smaller than that of the large protuberances. The main portion has large protuberance regions forming a plurality of large protuberances and small protuberance regions forming a plurality of small protuberances, the large protuberance regions and the small protuberance regions being alternately arranged in the circumferential direction of the main portion.
