Abstract: [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.

Abstract: 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 37, 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 tag 10 is 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.

Abstract: [Problems] To provide a plastic cap having a pouring cylinder capable of pouring the content liquid smoothly maintaining a constant liquid width even in case the degree of inclination of a container is varied to some extent at the time of pouring the content liquid, and of easily adjusting the liquid quantity. [Means for Solution] A bill 20 is formed at an upper end portion of the pouring cylinder 11 provided in a top panel 5 of a cap body 1, the bill 20 protruding outward in an inclined manner, a lower end of the pouring cylinder 11 is forming a seal surface 17 of nearly a cylindrical shape, a groove 30 is formed in the inner surface of the bill 20 in the pouring cylinder 11 and is extending from an upper end portion of the seal surface 17 up to an upper end of the bill 20, and a seal ring 29 is formed on the inner surface of the upper lid 2 so as to come into close contact with the seal surface 17 which is the inner surface of the pouring cylinder 11 when the upper lid 2 is closed.

Abstract: [Problem] To provide a plastic cap with an IC tag without interrupting transmission and reception of information to and from the IC tag, reliably inputting product information to the IC tag and reliably outputting product information that is input. [Means for Solution] The plastic cap has an IC tag 10 storing product information provided on the upper surface of a top plate 21. The top plate 21 is formed by an annular flange 35 and a recessed portion 37, the recessed portion 37 including a side wall 37a continuous to the inner circumferential edge of the annular flange 35 and a bottom 37b continuous to the lower end of the side wall 37a. The IC tag 10 is attached to the annular flange 35 so as to cover the recessed portion 37. A gap between the IC tag 10 and the bottom 37b is maintained to such a degree that the transmission and reception of signals to and from the IC tag 10 are not interrupted when the back surface of the bottom 37b comes in contact with water.

Abstract: 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.

Abstract: 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.
