[Problems to be Solved] In a synthetic resin container closure of a type which includes a body and a tamper evident bottom portion connected to the body via a plurality of breakable bridge portions arranged with spacing in a circumferential direction, and in which the body continues to be connected via unbroken connecting pieces to the tamper evident bottom portion continuously mounted on a mouth-and-neck portion of a container even after the bridge portions are broken to remove the body from the mouth-and-neck portion of the container, an improvement is made so that the container closure can be applied, without posing problems, even when the ascent distance of the body when removed is relatively long. [Means to Solve the Problems] Each of the unbroken connecting pieces is in such a form as to include two tilting portions whose tilting directions are opposite to each other.

A plastic cap with IC tag storing product information provided on the upper surface of a top plate. The top plate is formed by an annular flange and a recessed portion, the recessed portion, including a side wall continuous to the inner circumferential edge of the annular flange and a bottom continuous to the lower end of the side wall. The tagis attached to the annular flange to cover the recessed portion. A gap between the tag and the bottom is maintained to such a degree that the transmission and reception of signals to and from the tag are not interrupted when the back surface of the bottom comes in contact with water.

A closure to be applied to a container for holding a liquid such as shampoo. The closure comprises a closure body, a discharge liquid tube extending through the closure body and a reciprocating air pump mechanism built in the closure body. The air pump mechanism includes a cylinder whose discharge side communicates with the inside of the container and whose intake side communicates externally of the container, a piston, and a spring for elastically biasing the piston toward the intake side. The piston has a rod whose free end portion extends outwardly of the closure body.

A closure for containers comprises an automatic opening-closing mechanism and an outside closure member having a pour opening. The automatic opening-closing mechanism includes a plug member having a centrally formed air introduction hole and a plurality of liquid discharge ports formed around the air introduction hole, a first valve member for opening and closing the liquid discharge ports and a second valve member for opening and closing the air introduction hole.
