A container set includes a cover, a base, the cover having a cover sealing member which is made of elastic material and protrudes from a cover peripheral edge of the cover to allow the cover to engage the base, and a first container received between the cover and the base and having a container edge to allow the first container to engage an inner surface of the cover. In addition, the inner surface of the base has a base groove to allow the cover sealing member to engage the base groove when the cover engages the base, wherein the container edge, the cover sealing member and the base groove constitute an interlocking structure. With this interlocking structure, the cover, the base and the container(s) located therebetween can form a tightly engaged container set.

A storage box that includes a container, a lid for covering and sealing the container and a circular seal that encloses the lid. The lid includes a bottom plate, a top push plate, a cam body with sloping teeth, and a spring. The bottom plate includes a base that contains the spring and the cam body. The base includes stopping members and the top push plate includes sloping pushing teeth. The spring is positioned inside the base of the bottom plate and the cam body is placed on the spring. The top push plate is assembled on the bottom plate and the cam body is connected to the top push plate in a way that enables a rotational movement and a limited relative vertical movement. The lid is designed to be in a retracted close position or in an extended open position.

Apparatus and installation methods for sampling ports are disclosed. Sampling ports include a port housing and a lid assembly. The lid assembly is configured to sealably close against the port housing. Additionally, the lid assembly can be secured, such as with a lock, to the port housing. In one aspect, the port housing includes a sample mount arrangement configured to receive a sampling assembly. The sample mount arrangement defines a sampling channel and the port housing defines a sampling opening and a first securing mount. The lid assembly includes a latch arrangement and defines a second securing mount.

A container includes a molded fiber tray at least partially defining a tray internal volume. The tray includes a perimeter wall extending upward from a bottom tray surface, a rest extending outward from the perimeter wall, a parapet extending upward from the rest, and a tray build-up projecting inward from the parapet. The tray build-up and the rest at least partially define a gap therebetween. The container includes a molded fiber lid at least partially defining a lid internal volume. The lid includes a perimeter wall extending downward from a lid upper surface, and a ridge extending downward from the perimeter wall. The ridge includes an outer ridge wall, a lateral surface extending inward from the outer ridge wall, and a lid build-up projecting outward from the outer ridge wall. The lid build-up is configured to be received in the gap when the container is in a closed condition.

A container cover and assembly provide an extremely low profiled edge to the container cover when the container cover is secured or attached to a complementary container. Using such a low profile results in less of an edge being exposed such that its profile works to prevent inadvertent opening of the hinged lid from the container cover and also prevent removal of the container cover from the container. The container cover comprises two halves that are integrally-molded. The two halves are connected by a common pivot point or hinge that is disposed to one side of each half which allows the halves to be folded over and onto one another. The structure of the container cover and integrally-formed hinged lid can be formed using a one-shot plastic injection molding process. This simplifies and speeds up the production process for manufacturing the container cover and hinged lid combination.

A sealing structure for a lid and a container includes: the container including a hard material structure, a soft material structure connected to the hard material structure, and an opening at the top, the soft material structure includes a limiting portion, the limiting portion includes a container convex arc section and a container concave arc section connected to the container convex arc section; and the lid covering the opening to form an interference fit with the container, and including a locking portion capable of interlocking with the limiting portion, the locking portion includes a lid concave arc section abutting against the container convex arc section, and a lid convex arc section connected to the lid concave arc section and abutting against the container concave arc section. The sealing structure improves the sealing of the container, preventing leakage of liquid from the container, and making the container easy to carry.

A container has a fibrous lid (100) and vessel (110) that have mutually mating raised beads (104, 112). The beads are preferably formed in rings, which in the case of the lid is positioned on the underside of the cap, and in the case of the vessel is positioned at the mouth of the vessel. Also in preferred embodiments, the beads can have outward curls, inward curls, or have a split formation. Both lid and vessel are preferably made of at least 85 wt % paper. The non-paper percentages can advantageously comprise one or more of glues, adhesives, films, and/or moisture barriers, and in most preferred embodiments, the moisture barrier is also an adhesive.

A container system includes a container having a plurality of sidewalls and a rim extending from the sidewalls at a top of the container. The rim of the container includes a first sealing part and a second sealing part. Parts of the rim extend along arcs as viewed from above the container. The container system also includes a lid for sealing the container, with the lid having a rim that includes a first sealing part that is configured to contact the first sealing part of the rim of the container to form a first sealing area, and a second sealing part that is configured to contact the second sealing part of the rim of the container to form a second sealing area. Parts of the rim of the lid extend along arcs as viewed from above the lid. The container may be tightly sealed by the lid.

A packaged food product for being heated in an oven or heater includes a container with a food and a lid. The container includes an inwards raised bead at the inner wall of the container near the opening end of the container. The lid includes a recess designed to engage with the raised bead at the inner wall of the container in such a way as to snap-close the container. The food is located in the container.

A sealable container system contains a body and a lid assembly. The body includes an internal volume defined by bottom and side wall(s), bump(s) on the inside surface of the side wall and projecting toward the internal volume, and a lid with outer and inner walls at its bottom side with a channel in-between. A gasket couples to the lid with a wall portion residing within the channel and a lip outside the channel. When the lid assembly is pressed into the body, the lip of the gasket engages the bumps and deforms, and a gap forms between the lip and the side wall, where air in the internal volume exits through the gap. When the lip of the gasket travels past the bumps, the lip fully seats against the inside surface of the side wall, where negative air pressure is imparted to the internal volume of the body.
