Patent number: 9511906Abstract: A tamper-evident closure includes a tamper-evident strip connected with frangible connection points to a shoulder portion of a closure body before first time opening of the closure. In the closed position of a lid, a skirt portion of the lid is located behind the tamper-evident strip. The skirt portion includes locking lugs that protrude from the outer skirt surface towards the front and in the closed position of the lid engage an underside of the tamper-evident strip, such that upon a first-time opening the lid is only movable to the open position when the tamper-evident strip is permanently removed by breaking the frangible connecting points. The tamper-evident strip has bent end portions with frangible connection points that are bent towards the skirt portion, whereby a virtual straight line through these frangible connection points, seen from the front, lies behind a virtual straight line through the other frangible connection points.Type: GrantFiled: June 19, 2015Date of Patent: December 6, 2016Assignee: PLASTICUM NETHERLANDS B.V.Inventors: Jan van Alfen, Shi Ming Pun, Sebastiaan Wilhelmus Josephus den Boer, Gerrit Jan Stegeman

Patent number: 9409680Abstract: A tamper-evident dispensing closure includes a body adapted to be attached to a container. The container has a shoulder portion surrounding a dispensing opening. The closure body has a peripheral wall and a top wall which extends over one end of the peripheral wall, such that the corresponding end of the body is closed off by the top wall and an opposite end of the body is open. The open end is in use placed over the shoulder portion of the container. The top wall is provided with a dispensing passage which in use is in line with the dispensing opening of the container. The peripheral wall is provided with tamper-evident means, which cause the peripheral wall to rupture when the closure is removed from the container, thereby indicating tampering.Type: GrantFiled: November 13, 2012Date of Patent: August 9, 2016Assignee: Plasticum Netherlands B.V.Inventors: Jan van Alfen, Shi Ming Pun, Sebastiaan Wilhelmus Josephus den Boer, Gerrit Jan Stegeman

Patent number: 9340335Abstract: A closure assembly for a container includes a closure cap having an open ended body with a peripheral wall and a top wall provided with a dispensing passage which is defined by a collar arranged to the top wall. A self-closing valve is arranged in the closure cap. The valve includes a slit central portion and a skirt extending downwardly from the central portion, which has an outwardly extending flange. The skirt is arranged in the collar and the flange is located below the collar and extends radially outwardly beyond it. On a lower surface of the top wall, a plurality of lips is formed outward from the collar. The lips are folded over the flange such that the latter is partly enveloped between the lips and the top wall so as to secure the valve in the closure cap.Type: GrantFiled: January 10, 2014Date of Patent: May 17, 2016Assignee: PLASTICUM NETHERLANDS B.V.Inventors: Lenny Marita Ellenkamp-Van Olst, Sebastiaan Wilhelmus Josephus Den Boer, Gerrit Jan Stegeman, Jan Van Alfen

Patent number: 9090386Abstract: A tamper-evident dispensing closure includes a body adapted to be attached to a container and a pivotable lid which is hingedly attached to the body. A tamper-evident strip is located within the contour of the body and attached to the body by means of predetermined frangible connecting points. The tamper-evident strip is engaged or engageable by at least one locking member provided on a skirt portion of the lid, such that the lid is only pivotable to the open position when the tamper-evident strip is permanently removed. The body and the pivotable lid in the closed position define a recess in which the tamper-evident strip is received in a countersunk manner. The recess has a height which essentially corresponds to the height of the tamper evident strip such that the edges of the tamper-evident strip are essentially unreachable.Type: GrantFiled: November 13, 2012Date of Patent: July 28, 2015Assignee: PLASTICUM NETHERLANDS B.V.Inventors: Jan van Alfen, Shi Ming Pun, Sebastiaan Wilhelmus Josephus den Boer, Gerrit Jan Stegeman
