Container lid assembly

摘要

A container lid assembly is a lid unit for covering an upper-end opening of a container. The lid unit includes a lower connecting member peripherally mounted with a ring, an intermediate covering member, and an upper connecting member stacked in order. When the lid unit covers the container's opening and the upper connecting member is rotated manually, the lower connecting member is driven to move upward so that the ring at the periphery is pushed outward by the lower end of the intermediate covering member and closes the container's opening even more tightly, thereby providing desired sealing for the container.

主权项

1. A container lid assembly designed as a lid unit for closing an opening at an upper end of a container that is configured to contain eatable or uneatable objects, with the container lid assembly comprising a lower connecting member with a ring mounted around an outer periphery thereof, an intermediate covering member, and an upper connecting member;
with the lower connecting member having a depressed step at a predetermined site, and a lower guiding portion formed at an outer periphery of the depressed step, with the upper connecting member having an outer periphery configured to abut against a step depressed from an upper end of the intermediate covering member, with the intermediate covering member having an introverted pushing section extending outward from a predetermined downward facing site, with the upper connecting member having a connecting section extending downward from a predetermined site at a bottom thereof, with an upper guiding portion formed at an outer periphery of the connecting section, wherein the upper guiding portion works with the lower guiding portion of the corresponding step of the lower connecting member, wherein for covering the assembled lid unit over the opening of the container, the intermediate covering member has a bottom periphery thereof abutting against the opening, wherein the lower connecting member that has directional interference with the upper connecting member is placed in the opening, wherein when the upper connecting member is manually rotated, the upper guiding portion draws close or pushes away the corresponding lower guiding portion of the lower connecting member, and the introverted pushing section of the intermediate covering member pushes the ring at an approaching end of the lower connecting member outward, to close the opening of the container tightly.
