Background of the Invention
1. Field of the Invention
[0001] The present invention relates to a container lid which includes a sensing system
and a transmission system actuated to cause the container lid to move to an open position
in response to a signal from the sensing system.
2. Description of the Related Art
[0002] A container includes a lid which can open automatically to allow the user to throw
things into the container is known and is available in market. Such container generally
includes a sensor and a motor, and the motor is installed to the container, either
inside or outside.
[0003] Patent
W02006/084774 shows a waste collector including a container and a lid mounted above an opening
of the container in order to close the opening. The lid opens automatically when a
sensor detects an approach of an object and is driven by an electrically powered transmission
assembly. The transmission assembly includes a motor mounted inside a cover disposed
on a side of the lid. Further, a spring is used to cause the lid to return to an unopened
position. The waste collector is characterized in that the motor is disposed outside
the container and it operates an actuating member to move upwardly and downwardly
for operably moving a T member to open and close the lid.
[0004] When removing the lid from the container for the purpose of emptying trashes inside
the container or arranging a bag inside the container, it is difficult to carry and
transport the lid in a balanced state and is likely to drop inadvertently. The lid
and the motor are damaged if dropped. Furthermore, because the motor and the cover
project outside the container they are liable to be bumped easily and the lid has
an increased volumetric size, which results an increased packaging cost.
[0005] The present invention is, therefore, intended to obviate or at least alleviate the
problems encountered in the prior art.
Summary of the Invention
[0006] According to the present invention, a container lid is adapted to be releasably mounted
on a container includes a base adapted to be releasably mounted on the container in
order to allow the container lid to be releasably supported on the container. The
base includes a hole extending therethrough and adapted to align with and communicate
with an opening of the container when the container lid is supported on the container.
The container lid also includes a control mechanism mounted and bore on the base and
disposed within a circumferential edge thereof. The control mechanism includes circuit
board, a motor, a transmission system, and a sensing system. The container lid further
includes first and second hoods pivotally mounted and bore on the base and disposed
within the circumferential edge thereof. The first hood is engaged with and driven
to pivot by the control mechanism. Moreover, the first and second hoods are structurally
connected to each other in a manner that the pivoting of the first hood would cause
the second hood to pivot oppositely from the first hood. Additionally, the first and
second hoods are arranged symmetrically and disposed above the hole and moveable between
a first operation position such that the first and second hoods cooperate to prevent
a foreign object to pass therebetween and a second operation position such that the
first and second hoods are apart and have a gap therebetween through which the foreign
object is adapted to be passed and moves into the hole.
[0007] It is an object of the present invention to provide a container lid that the carrier
can be carry it easily and stably.
[0008] It is another object of the present invention to provide a container lid that resolves
the problem of having an increased volumetric size, which results an increased packaging
cost.
