A container including a base and a lid that is releasably attached to the base. The lid includes a channel that extends around a perimeter of the lid. At least one inlet opening provides fluid communication between an interior of the container and the channel, and at least one outlet opening provides fluid communication between the channel and atmosphere.

A container package includes a container and a lock-on closure that couples to the container. The container includes an annular sidewall. The closure includes a channel portion having an inner, an outer, and a top wall that define a channel. The inner wall includes a primary seal having sealing ridges formed thereon. The closure further includes a single, flexible sealing wiper appendage extending away from the top wall. When the sidewall of the container is outside of the channel, the appendage is in a first position in which it extends downwardly and is angled inwardly so a terminal end of the appendage is freely suspended within the channel. When the sidewall of the container is in the channel, the appendage is in a second position in which the terminal end is closer to the inner wall than in the first position and the appendage contacts the top rim.

A novel container and container system is herein disclosed. Each container includes a main body, at least one male connection member, and at least one female connection member. The connection members are arranged on the main body in a manner that easily coupling of adjacent containers is facilitated, as well as a wide range of potential configurations of coupled containers.

A tamper-evident container generally includes a tray having an opening with a step section formed around the opening and including a first protrusion section that is provided with a first coupling unit with a first perforation line formed therebetween. The first coupling unit includes a coupling trough. A cover includes a concave groove having a bottom and an outside surface engageable with the step section to close the opening. The cover includes a second protrusion section and a second coupling unit between which a second perforation line is formed and projecting beyond the first perforation line. The second coupling unit has a coupling member receivable in and engageable with the coupling trough. Tearing off the first and second perforation lines allows the first and second coupling units to detach from the tray and the cover, respectively with the second protrusion section projecting outside the tray for easy gripping.

A tamper-evident container formed by thermoforming includes a tub having a bottom and a sidewall forming an interior volume. The container has a lid with an edge extending peripherally outward therefrom which is configured to mate with the tub edge to close the container. The lid edge has an inner portion and an outer portion with a perforated section therebetween. The perforated section extends continuously around the entire periphery of the lid, whereby the outer portion forms a tamper-evident seal removable from the inner portion for removing the lid from the tub.

A tamper-evident container formed by thermoforming includes a tub having a bottom and a sidewall forming an interior volume. The container has a lid with an edge extending peripherally outward therefrom which is configured to mate with the tub edge to close the container. The lid edge has an inner portion and an outer portion with a perforated section therebetween. The perforated section extends continuously around the entire periphery of the lid, whereby the outer portion forms a tamper-evident seal removable from the inner portion for removing the lid from the tub. Texture elements are distributed around the outer portion of the lid edge which are configured to provide a visual indication of the presence of the tamper-evident seal. The tub edge is disposed beneath the outer portion of the lid edge and extends peripherally outward so that a substantial part of the outer portion of the lid edge does not extend below the tub edge in a vertical direction of the container in an upright orientation. A tab extends from the outer portion of the lid edge and below the tub edge in the vertical direction of the container.

A height-adjustable container is configured such that an upper body and a lower body thereof are rotated from side to side in a zigzag form while coming into close contact with each other, so that the height of the container can be easily adjusted. The present invention enables the height of a container to be adjusted, whereby it is possible to make better use of a space of a refrigerator, a cabinet, or the like, in which the container is stored.

A container, that prevents an illegal operation and can be easily identified after being illegally operated, includes a bowl-shaped base and a cover selectively closing the bowl-shaped base, wherein a pre-broken structure is formed on the cover and the cover cannot be smoothly detached from the bowl-shaped base before the pre-broken structure being damaged. For the market, the salesperson easily confirms that the container has been illegally operated and the illegally operated container is replaced in time for providing fresh good to the consumers. For the consumers, the illegally operated containers can be easily confirmed and eliminated through choosing for preventing from buying unsafe or stale goods, particularly foods.

The first coupling unit includes a coupling trough. A cover includes a concave groove having a bottom and an outside surface engageable with the step section to close the opening. The cover includes a second protrusion section and a second coupling unit between which a second perforation line is formed and projecting beyond the first perforation line. The second coupling unit has a coupling member receivable in and engageable with the coupling trough. Tearing off the first and second perforation lines allows the first and second coupling units to detach from the tray and the cover, respectively with the second protrusion section projecting outside the tray for easy gripping.

A container includes a casing having an opening and a first abutting edge surrounding the opening. A cover is selectively mounted onto the casing for closing the opening, wherein the cover has a second abutting edge laterally extending therefrom and abutting against the first abutting edge when the cover closes the opening. A puller extends from the second abutting edge of the cover. A snapping device is formed between the casing and the puller. The snapping device includes a plug formed on the puller and a socket defined in the casing for temporarily receiving the plug and holding the plug in place. A weakened portion is formed on at least one place of the puller such that the puller is irreversibly curved after being lifted due to the weakened portion and the curved puller is used as a basis for easily identifying whether the container is illegally operated or not.
