Tamperproof closures for use on a container are disclosed. The closure includes a base which can be arranged on a container port and can be connected thereto in a fluid-tight manner as well as a closure part connected to the base via a predetermined breaking point. Each of the base and the closure part includes at least one force-enhancing means by which a movement of the base and the closure part relative to each other can be force-assisted in terms of destruction of the predetermined breaking point. The movement of the base and the closure part relative to each other can be a rotary movement of the closure part with respect to the base in the opening direction of the closure part and each force-enhancing means can be a handle in the form of a lever projecting radially from both the base and the closure part with respect to the axis of rotation of the rotary movement.

Disclosed is an airtight container in which a lid is easily opened by the principle of the lever thus preventing broth from splashing out when the lid is opened. The airtight container includes a container body having a latching bump and a bent flange, a rotating knob connected to the flange and having an opening-closing plate and a step portion, and a lid having a latching protrusion, a downwardly bent flange and a lid extension portion, wherein, when the rotating knob is just rotated upward in a state where the lid is coupled to the container body, the opening-closing plate lifts the lid extension portion by the principle of the lever while the step portion prevents the lid extension portion from spreading outwards, thereby allowing the latching protrusion to be released from the latching bump and the lid to be opened from the container body.

The present invention relates to a closure means for closing the opening of a container, said closure means comprising: a) a lid assembly, comprising: a lid cover, configured to provide an upper plate and a lower plate connecting said upper plate via standing wall therebetween, said upper plate is provided with at least one hinge member; at least one wing member comprising a handling portion, a flipping portion, and a stopper portion, said wing member pivotably connecting to said lid cover at said hinge member and thus movable between a first position where said stopper portion being away from said upper plate of said lid cover and a second position where said stopper portion being engaged with said upper plate of said lid cover and thus the upward movement of said wing member with respect to said lid cover being limited; and b) a sealing element, fittingly mounted around said standing wall of said lid cover; and characterized in that, in a first configuration where said container being closed with said closure means, said wing member being moved from said first position to said second position causing said closure means being moved upwards automatically.

A container for loosely stored products including a container body, a cover for closing an opening end of the container body, the cover being movable between a closed position closing the opening end of the container body and an open position, and an opening part provided on the container body wherein the opening part includes a pushing element with a contact portion, and a lifting portion positioned, in the closed position of a cover, beneath an abutment of the cover, the contact portion of the pushing element being arranged to be pushed away from the opening end of the container body such that the lifting portion displaces the abutment of the cover.

A food container includes a box, a cover and a pair of locking wings. The box includes a main body and elastic engaging plates. The main body has a receiving space. The elastic engaging plates are arranged on opposite sides of the receiving space. Each elastic engaging plate includes an elastic arm and a clip. The cover includes a cover plate and engaging slots. The cover is positioned on the main body through the clip inserted in the engaging slot. The locking wings are pivotally coupled to the cover. Each locking wing rotates toward the box to press elastic arms. The elastic arms drive the clips to be disengaged from the engaging slots. Thus, the cover is separated from the box.

A lid assembly for a beverage container having a lid housing, a seal assembly and a trigger member. The seal assembly has a drink seal to close the drink aperture. The seal assembly is rotatedly connected to the lid housing and movable between a use position and a cleaning position to allow the drink aperture to be open for cleaning. The trigger member is connected to the lid housing and is capable of engaging the seal assembly in the use position, but it cannot engage the seal assembly in the cleaning position. Additionally, a trigger lock is connected to the lid housing to prevent engagement of the seal assembly by the trigger member when the trigger lock is locked. The trigger lock may also contain a visual indicator to indicate that the lock is in the locked position.

A lid assembly for attachment to a drinking vessel is provided having a camming lever rotatably attached to an upper portion of a lid main body, and a sealing member rotatably attached to a lower portion of lid main body. Rotation of the camming lever between a forward and rearward position in an elongated recess of the lid main body selectively seals and unseals a drinking aperture in the lid main body. A locking member is operable to selectively secure the rotational position of the camming lever when the sealing member is in a sealing position sealing the drinking aperture. A cam axle of the camming lever is removably attachable to an attachment element of the sealing member to transition the lid assembly between a use configuration for drinking and a cleaning configuration in which the lid assembly may be thoroughly cleaned.

Each locking wing rotates toward the box to press elastic arms. The elastic arms drive the clips to be disengaged from the engaging slots. Thus, the cover is separated from the box.

A beverage container closure or lid adapted for closing an open end of a beverage container. The lid is couplable to the beverage container and includes a selectively openable stopper that when closed, creates a fluid-tight seal between the beverage container and the environment. The stopper may be opened by pressing a button disposed on a side of the beverage container closure. The stopper is subsequently automatically closed when the button is released. Thus, the user may open and close the beverage container closure using a single hand without the need to remove the beverage container closure from the beverage container. The beverage container closure includes an actuating lever configured to press the button when a user applies a force to the lever. By utilizing the mechanical advantage provided by the lever, a user is able to selectively open and close the stopper using a relatively low amount of force.
