POUCH CLOSURE ASSEMBLY WITH TAMPER INDICATION

摘要

A container closure assembly includes a cap and a spout assembly. The cap includes an internal thread that is configured to engage with an external thread located on the spout assembly. The cap further includes an engagement prong assembly that is configured to engage with the cylindrical band located on the spout assembly. The cylindrical band is supported by a plurality of tabs such that the engagement prong assembly extends between the band and the external threads when the internal and external threads are engaged and the cap is rotated such that the interaction of the threads moves the cap toward the band, the engagement prong assembly engaging the band when the cap seals the open end of the hollow cylinder, and the engagement prong assembly breaks the tabs when the cap is rotated causing the cap to unseal the open end.

主权项

1. A container closure assembly comprising:
a cap including a hollow rim which provides an external gripping surface; a closed cylinder including a closed end, an open end and an internal thread extending from the open end toward the closed end, the cylinder including an engagement prong assembly; a support structure for supporting the hollow rim outside of the cylinder so that fluid flow is permitted between the hollow rim and the cylinder, and rotational force can be transferred between the rim and cylinder; and a spout assembly including a hollow cylinder including an open end and an external thread configured to interact with the internal thread, a cylindrical band supported by a plurality of tabs relative to the cylinder such that the engagement prong assembly extends between the band and the external threads when the internal and external threads are engaged and the cap is rotated such that the interaction of the threads moves the cap toward the band, the engagement prong assembly engaging the band when the cap seals the open end of the hollow cylinder, and the prong assembly breaks the tabs when the cap is rotated such that the interaction of the internal and external threads causes the cap to unseal the open end.
