The container includes a base and a lid pivotally coupled to the base. The base includes a bottom wall and a peripheral wall, where a plurality of receptacles are defined in the peripheral wall. The peripheral wall is configured to be moved from a relaxed position to a flexed position by applying a first force to a first portion of the peripheral wall in a first direction and a second force to a second portion of the peripheral wall in a second direction. The lid includes a top wall and a plurality of projections. In the relaxed position, the lid is configured to engage the receptacles so as to retain the lid in a closed configuration. The container is configured to be moved from the closed configuration to an open configuration by moving the lid in a third direction while the peripheral wall is in the flexed position.

A package includes a base, a lid, and a locking mechanism. The locking mechanism includes an arm and a flexible member. The arm extends from the lid and has a first engaging structure. The member includes a flexible rib connected to a base floor, and a second engaging structure and a contact structure on a rib outer surface. The member flexes in response to a first force applied in a first direction to the contact structure and relaxes in response to absence of the first force. The member engages the first and second engaging structures based on the member being relaxed while the lid is closed. The member disengages the first and second engaging structures based on the member being flexed while the lid is closed. The lid may be opened based on applying a second force to the lid in a second direction while the member is flexed.

The package includes a base, a primary lid connected to the base via a first hinge, the primary lid and the base defining a primary storage area when the primary lid is in a closed position, a first locking mechanism, and a second locking mechanism. The first locking mechanism and the second locking mechanism each include a flexible member including a first and second segment connected by an elbow, the first segment being connected to the primary lid, a distal end of the second segment including a contact structure, the second segment including a first engaging structure, a second engaging structure on an interior wall of the base, the flexible member being in a first position when the primary lid is in the closed position, the second engaging structure being retained by the first engaging structure to lock the primary lid onto the base in the closed position.

The present invention provides a storage tank which comprises a tank body and a sealing cover. A top of the tank body is provided with a tank mouth; the sealing cover can seal the tank mouth; the sealing cover comprises a main cover, a cover plate, a sealing ring, an annular extrusion part and a sealing switch; a top of the main cover is provided with an accommodating groove; the cover plate is covered on the accommodating groove; an edge of the cover plate is covered on the tank mouth; the sealing ring is sleeved and fixed on the outer circumference of the main cover; the annular extrusion part is slidably sleeved on the main cover below the sealing ring ; the sealing switch is located in the accommodating groove. The storage tank has good sealing effect, simple operation and convenient use.

A bottle assembly is provided including a bottle having an end portion with a first detent formation, and a collar having a second complementary detent formation. The collar is arranged to snap fit to the end portion by engagement of the detent formations by application of force only in a direction towards the bottle. In addition, a valve assembly for use with a drinking vessel is provided including a base member and a sealing member. The sealing member is movable, dependent on a pressure difference across it, between a sealed position, wherein the sealing member is sealed against the base member, and an unsealed position, wherein the sealing member is unsealed from the base member. One or more channels are formed between the base member and the sealing member and are arranged to allow air to enter the drinking vessel when the sealing member is in the unsealed position.

A container including a lid, a first body, a second body and a latch is provided. The first body connects to the lid by a first hinge for pivoting between a lid closed position and a lid open position. The first body defines a storage cavity. The second body connects to the first body by a second hinge for pivoting the first body relative to the second body between a first body closed position and a first body open position. The second body defines a storage cavity. The latch is attached to the second body. The latch is transitionable between a latched position in which the latch engages the lid and prevents transitioning either the lid or the first body to the corresponding open positions.

Lids for a container having an external peripheral rim at the upper end thereof, the lid comprising a top wall; a peripheral skirt depending downward from the top wall and having a bottom edge larger in diameter than the rim of the container and an inside surface with a locking mechanism disposed between the bottom edge and the top wall and being adapted to receive and engage the rim; and a plurality of slots defined in skirt extending upward from the bottom edge to divide the skirt into individually resiliently flexible skirt portions.

A closure system with a three-dimensional structure with an opening and a lid for plugging onto the three-dimensional structure in order to close the opening. The lid is bistably deformable between a first state, in which its end wall is curved in the plug-in direction, and a second state, in which the end wall is curved against the plug-in direction. An annular edge section of the lid has a greater outer circumference in the first bistable state than in the second bistable state and forms a clamping fixture of the lid to a wall region of the opening when the edge section is pressed inwards in the first state or outwards against the wall region in the second state. The three-dimensional structure transfers a force from the outside at specified locations that to a snapping process of the lid from one to the other bistable state.

The present invention is directed to a child resistant double seam container lid including an adapter ring for securely affixing to the double seam top rim of conventional double seamed containers that will be difficult for children to open, yet readily openable by adults. More particularly, a one-piece, two-piece, and three-piece child resistant double seam affixable container lid is provided having a first piece lid portion first, a second piece adapter ring locking member second piece and optionally a third piece securing unit piece, with rotational alignment indicators, and optional additional integral features such as a liquid measuring cup feature, a liquid tight lid feature, a threaded lid portion, a replaceable double seam container lid portion and a double seam container lid locking member adapter ring securely affixable to the double seam container.
