  • Patent number: 5871111
    Abstract: In the case of over-tightening of the closure-cap on a beverage bottle (through turning in the wrong direction) there is the risk that, due to the high internal pressure, not only will the thread jump, but also that the cap will be ejected directly from the container. In order to avoid this risk, the invention proposes a screwable closure-cap with security against over-tightening. This cap possesses a ramp element (3) on the end of the thread oriented towards the cap-base, said ramp element being able to engage with the thread-start of the container mouth in the case of over-tightening of the closure-cap. As a result, the cap-wall in the area of the ramp element will be forced outwards in the case of over-tightening so that jumping of the thread in this region will be facilitated. In this way, jumping of the thread on one side only--on the ramp element side--will be achieved when over-tightening is continued, so that ejection of the closure-cap will not be possible.

  • Patent number: 5791506
    Abstract: A display-type container for cosmetics and the like, includes a flat jar having a neck portion with an external screw thread, and a ring-shaped screw cap member that is mounted on and cooperable with the neck portion. The latter has an annular sealing lip, and a plastic panel member which is disposed in the ring-shaped screw cap member provides underside sealing areas or surfaces that are engaged with the sealing lip. Portions of the screw-cap member and panel member are disposed in overlying relation, the two members being centralized with one another, and forming a unitary closure assemblage. The arrangement is such that the sealing areas of the panel member are forced by the screw cap member, into substantially air-tight sealing engagement with the sealing lip of the jar. The seal does not depend on the engagement of the threads, or upon any incidental sealing therebetween, which may or may not occur.

  • Patent number: 5769255
    Abstract: A plastic container closure comprising a top panel, a skirt portion, an annular protruded portion that is formed inwardly from the inner surface of the top panel and on the inside of a portion near the root of the skirt maintaining a small gap therebetween, and a sealing liner that is fitted by press-molding on the inside of the top panel, wherein a substantially vertical portion is formed on said liner along the inner surface of the annular protruded portion, and sealing performance is maintained by the engagement between the outer edge of the mouth of the container and the substantially vertical portion. Since the sealing is accomplished over a surface having a predetermined width in the up-and-down direction, the sealing performance is not impaired even when the top panel is deformed by the pressure. Moreover, favorable sealing performance is maintained even against shock that is given to the container at the time of fitting the closure.

  • Patent number: 4122965
    Abstract: A closure for glass containers is formed with a top end wall and a depending annular skirt wall. A base ring depends downwardly from the top end wall and supports a small sealing fin which projects downwardly from base ring to engage the finish of a glass container neck in sealing relation when the closure is applied to the container. The preferred base ring is tapered downwardly and outwardly and facilitates the flow of plastic into the sealing fin during molding of the closure. The closure is threaded onto the container neck and the sealing fin comes into contact with the finish. The application of additional closure torque causes the sealing fin to deform and be crushed. Polypropylene has the desired structural properties of flexural stiffness, hardness and compressive strength to be used for the closure.
