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 suture package for retaining a barbed suture is provided. The suture package includes a suture retaining member including an outer wall and an inner wall. The inner wall is radially spaced from the outer wall and defines a suture retaining area therebetween. The inner wall defines a needle retaining area and includes at least one opening therein to permit reception of at least one suture therethrough. The outer wall includes a plurality of inwardly extending tabs configured to engage a cover. The suture package further includes a cover configured to be received within the outer wall of the suture retaining member and to selectively engage the inwardly extending tabs formed thereon.

A vacuum-drawing lid can include a base frame with a first one-way valve, a piston with a second one-way valve, and a cylindrical cam with a sinusoidal groove formed on an inner surface thereof to drive reciprocation of the piston as the cylindrical cam turns. Turning the cylindrical cam in a first direction can drive the piston to translate in a first direction and actuate the first valve. Turning the cylindrical cam in a second direction can drive the piston to translate in a second direction and actuate the second valve.

An airtight container has a lid which 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.

A plastic container capable of assuming a loading state, an initially sealed state and an opened state comprises a lid including a lid rim and a base having a base rim. The lid rim sealingly engages with the base rim. A projecting portion has an accordiated section and a pull tab that projects outwardly from the lid. The accordiated section has at least one pleat. The projecting portion includes a frangible bridge. When the plastic food container is in the initially sealed state, the accordiated section has a first length and a first orientation relative to the projecting portion. When the container is in the initially sealed state and a first pulling force is applied to the pull tab, the frangible bridge ruptures. When the frangible bridge ruptures and before the lid is separated from the base, the container is in a tab-employed state in which the accordiated section springs outward and has a second length visibly longer than the first length.

A container includes a lid having a peripheral flange which defines a lifting tab. The container includes a base having an upper peripheral rim. A bend line is formed in a surface of the base to define a bendable portion of the base. The bendable portion of the base receives and limits access to the lifting tab when the container is closed. A container includes a lid having a peripheral flange which defines a lifting tab. The lifting tab has a top surface and a bottom surface. The lid includes a protrusion extending downwardly from the bottom surface of the lifting tab. The container includes a base. The base has an aperture formed in a portion of the base to receive the protrusion of the lid when the container is closed.

A suture package for retaining a barbed suture is provided. The suture package includes a suture retaining member including an outer wall and an inner wall. The inner wall is radially spaced from the outer wall and defines a suture retaining area therebetween. The inner wall defines a needle retaining area and includes at least one opening therein to permit reception of at least one suture therethrough. The outer wall includes a plurality of inwardly extending tabs configured to engage a cover. The suture package further includes a cover configured to be received within the outer wall of the suture retaining member and to selectively engage the inwardly extending tabs formed thereon.

A cooler has a body and a lid that co-operate. The lid is movable between closed and open positions. The lid is a freezable reservoir. A filler port is located inside the lid. The entrance of the filler port into the lid is located at a height part way between the inside and outside walls of the lid. The lid has a downwardly extending hollow peripheral formation. The filler port is spanwise inset from the peripheral formation. The lid has spanwise extending internal formations that stiffen the lid and divide the internal chamber into sub-volumes connected by necks through which liquid can flow. The inside and outside walls of the lid may be connected. The lid is provided with a fill to line visible from the filling port to discourage over-filling. The lid may have an insulated cap, and the cooler may have an insulated jacket.

A tamper evident closure includes a first snap, a second snap, a tear strip connected to the second snap, a third snap connected to the tear strip, and a first projection extending around three sides of the first snap. In a closed position, a cavity of the second snap is configured to be placed over the first snap, and the third snap is configured to be placed in a cavity in the first snap. Further, in a closed position, the first projection is configured to surround three sides of the third snap that has been placed in a cavity in the first snap.
