The present invention relates to an airtight container that is usually used to keep foodstuffs including food and drinks. The airtight container includes: a container part; and a lid part configured to be locked to the top of the container part, in which the lid part has a two-step opening/closing structure to partially open the container part or to completely open the container by being separated from the container part when the lid part is locked to the container part. The lid part includes: a body having locking portions integrally formed such that the body can be locked to the container part on the top of the container part; and a lid plate hinged at a side on the body part to be rotatable, having integral locking portions to be able to be locked to the container part, and used to open a portion of the container part with the body locked to the container part.

According to the present invention, it is possible to open/close the lid part fastened to the container part in two steps of partial opening/closing and complete opening/closing, increase ease and convenience in use, achieve stable sealing force at the container part and the lid part, and increase durability of the product such as preventing contraction when forming the product.

A one-piece polymeric closure includes first and second closure portions. The first closure portion includes a first polymeric top wall portion and a first polymeric annular skirt portion. The first annular skirt includes a first set of splines on an inner surface thereof and knurls formed on an exterior surface thereof. The second closure portion includes a second polymeric top wall portion with a pull ring and a second polymeric annular skirt portion The second annular skirt portion includes a second set of splines on an outer surface thereof, an internal thread formation, and a locking ratchet band. The first and second sets of splines are configured to interact with each other when the polymeric closure is in a closed position. The polymeric closure opens by flipping the first closure portion with respect to the second closure portion via a hinge.

Method for providing a container with food, the method comprising: providing a container for infant formula food, adding the food, sealing the container with a gas-tight membrane seal, adding an inner scannable code on the gas-tight membrane seal, closing the container with a tamper-proof closure means, so that the inner scannable code is not scannable without breaking a part of the tamper-proof closure means, and storing the inner scannable code in a database.

A device configured to maintain or preserve products sensitive to environmental triggers, such as moisture or oxygen, can include a lid (24) removably attachable to a body (16) of a container (10) in which the sensitive product (23) is stored. An active agent (12) capable of preventing, or at least slowing, exposure of the sensitive product to the environmental trigger is positioned in or under the lid. A utensil (40) configured to shield the active agent can be removably attached to an underside of the lid and positioned to cover the active agent when the utensil is attached to the lid. Upon removal of the utensil, the active agent is unshielded and, upon exposure to the environment, is activated to absorb or consume at least some of the environmental triggers within the container.

A closure includes a pivoting closure cap and a closure base configured to more easily align and securely pivot open without uncoupling. In various embodiments, the pivoting closure cap includes a pair of hinge assemblies including hinge pins pivotable between a closed position and an open position where the pivoting closure cap is opened for pouring. The closure base includes a pair of hinge pin receivers with a hinge pin sockets. The hinge pins located and rotatable within the sockets.

A container, includes a collapsible portion and a container base. The collapsible portion has a first step structure; a second step structure; and a hinge assembly coupled between the first step structure and the second step structure. The container base is coupled to the collapsible portion. Another container includes a container base; a collapsible portion, coupled to the container base; a lid base, coupled to the collapsible portion; a ring, coupled to the lid base and sandwiching a periphery of the collapsible portion with the lid base; and a lid assembly, coupled to the ring when the container is in a closed status.

A combined lid and strainer device for a paint container features an outer mounting rim configured for mated fitting onto a rim of the paint container. Within a central circular area surrounded by the rim, there is a perforated a straining area through which paint is pourable. A movable cover is selectively movable between a closed position overlying the perforated straining area, and open positions withdrawn therefrom to allow strained pouring of the paint therethrough. Raised features on the cover are used to secure the cover closed when the lidded container is placed in a paint shaker. A sealing membrane is used, at least initially, seal the perforated area in airtight fashion to maintain paint freshness. Securement features are usable to secure the flap in both closed and open positions.

A two part container lid for a container including a separately moulded brim mount part with a hatch opening in a top portion, reversibly clamped onto an rolled rim of the container and a separately moulded hatch cover part, sized and shaped to reversibly fit over the hatch opening. The hatch cover part is coupled to the top wall of the brim mount part by a detachable hinge thus pivoting the hatch cover part over the hatch opening between a fully closed position and a fully opened position and any intermediate position therein, thereby providing access to the beverage within the container without removing the two part container lid from the container. Detaching the hatch cover part from the brim mount part converts the two part container lid into a hybrid lid covering partially covering the container while permitting access to the contents within the container through the hatch opening.

A container is provided according to an embodiment of the present disclosure. The container may include a container part in which an accommodation space configured to accommodate contents is formed, a middle body configured to communicate with the accommodation space and coupled to the container part to surround at least a portion of the container part, an inner cover rotatably connected to the middle body to open or close the accommodation space, and an outer cover rotatably connected to the middle body to open or close the middle body.

A card-based package for sensitive food products, comprises a container portion defining an interior space with a base and a sidewall extending to an upper peripheral edge for receiving a removable seal for hermetically sealing the container portion prior to use. The package further comprises a lid structure, that can open and close to allow selective access to the interior space after removal of the seal. The container portion and the lid structure are both formed of card-based material and at least the container portion has light, oxygen, and water vapour barrier properties sufficient for storage of the product for a period exceeding 24 months.
