The present invention provides a lidded container which, even when a flange portion of the container warps during microwave heating, can prevent a contact between the flange portion and a lid and allows steam to pass from a steam escape mechanism.

The lidded container is provided with a container having an opening and a lid which covers the opening and is joined to the container. The container is provided with a bottom portion, a side portion standing upright from the bottom portion, and a flange portion which is continuously connected to an upper portion of the side portion and includes a first plane. A circumferential seal portion is formed between the lid and the first plane of the flange portion. The seal portion is provided with a main seal portion and a protruding seal portion protruding inward with respect to the main seal portion. At least one of the flange portion and the lid is formed with a contact suppression mechanism for suppressing a contact between the flange portion and the lid, which is provided outside the protruding seal portion at a position corresponding to at least the protruding seal portion.

A closure member for a food container comprises a multilayer laminate peripherally delimited by its peripheral edge having a predetermined shape suitable for covering an opening of a corresponding container and defining at least one hand gripping portion for a user. The multilayer laminate is provided with a first layer of material, preferably at least partly light permeable, a second layer of preferably plastic material, a third layer of repositionable adhesive material interposed between the first and the second layer and at least one anti-adhesive strip interposed between the first and second layer and placed near the hand gripping portion.

A closure body (40) is provided for installation with a liner membrane (52) on a container (44). The closure body (40) has a peripheral portion (74) for being mounted on the container (44) around an access opening (48), and a separable portion (82) that (i) is disposed laterally inwardly of the peripheral portion (74); (ii) is initially connected to the peripheral portion (74) by at least one frangible connection (86); and (iii) can be separated from the peripheral portion (74) upon breaking of the at least one frangible connection (86). The closure body (40) has an opening member (94) that is connected with the separable portion (82) to accommodate movement of the opening member (94) relative to the separable portion (82). The opening member (94) has a grippable portion (102) and a puncture portion (106) each disposed in an initial inactive orientation relative to the separable portion (74).

Provided is a portion container whose detaching seal portion can be easily detached by a stress applied from a radial inner side based on an inside pressure of a container body, but can be hardly detached by a stress applied from the outside during distribution. Provided also are a seal head for sealing such container and a container sealed with using such seal head. The seal head includes pressing end portions for pressing a lid member against a flange of an opening. At least a portion of the pressing end portions is formed as an uneven projecting portion having different curvature radii in its cross sectional contour between a radial inner portion and a radial outer portion of the opening.

An ink cartridge contains an outer package, an ink container within the outer package, and sheet bodies attached to an outer surface of the outer package, and is attachable to and detachable from a printing device. Small pieces are formed by cuts in the outer package. The small pieces include breakable sections, and the bendable sections. Sheet bodies cover a portion of the small pieces. Pressing on a small piece with a finger breaks the breakable section, and bends the bendable section to press them inside the outer package. A portion of the sheet body then shifts upwards so that the sheet body can be grasped with fingers and peeled away from the outer package. Disassembly and sorting of used cartridges in this way becomes easier.

The closure body (40) has a peripheral portion (74) for being mounted on the container (44) around an access opening (48), and a separable portion (82) that (i) is disposed laterally inwardly of the peripheral portion (74); (ii) is initially connected to the peripheral portion (74) by at least one frangible connection (86); and (iii) can be separated from the peripheral portion (74) upon breaking of the at least one frangible connection (86).

Cut portions of packaging material can be used as film lids that are respectively heat sealed to mouths of cups of carbonated beverage to close openings of the cups. The film lids can be configured in a manner that seeks to optimally maintain both package integrity and beverage freshness, and provide selective access to the carbonated beverage. The film lids can include diffusion-controlling microperforations. The film lids can include access-providing score lines.
