A can lid that enables a tab to be easily pulled up. A tab has a leading end positioned inside a predetermined opening area bordered by a score and a rear end positioned on an opposite side to the leading end relative to a portion where the tab is fixed to a lid body, and a sliding member is provided which is configured to slide in a state where a part thereof penetrates into a gap between the lid body and the tab, the sliding member having an insertion section which is configured to move the rear end of the tab in a direction away from a surface of the lid body when the sliding member is caused to slide from an initial position.

An anti-opening container includes a first box and a second box. The first box includes a first body, a first box section and a first gripping section. The first box section is formed by the extension of the first body. The second box includes a second body, a second box section, a second gripping section, an extension section, and a fastener section. The second box section is formed by the extension of the second body. The fastener section is connected to the extension section via a perforated line. The fastener section is embedded in the first box section. When the first gripping section and the second gripping section are displaced in opposite directions, the perforated line breaks, and the first box section and the fastener section are separated from the second box section together to separate the first box and the second box.

Provided is a container whose shape for discharging contents is hardly expandable laterally, the container including a container body holding contents and a lid member for closing an opening of the container body which are sealed with each other by an annular seal portion formed along a flanged face of the opening. At a specified position of the annular seal portion, there is provided a detaching seal portion which is to be detached by an increase of inside pressure inside the container body in association with deformation of the container body based on an external force. An outflow channel for discharging the contents therethrough extends radially outwards from the detaching seal portion. At a position of the container body corresponding to the outflow channel of the flanged face, there is formed an outflow groove which is sunk toward a bottom portion of the container body.

Provided is a container that allows a portion where detachment starts to be fixed at a specified position in a more reliable manner, thus allowing contents to be discharged in a direction expected by a user, allowing eventually reduction in the amount of contents to remain in the container in the end. The container includes a container body holding contents therein and a lid member, the container body and the lid member being sealed by an annular seal portion formed along a flanged face of the opening. There is provided a detaching seal portion which is detached in response to increase of pressure inside the container body associated with deformation of the container body. The detaching seal portion includes a reverse-oriented annular seal portion which occupies a part of a width of the flanged face and which projects toward a radial inner side of the opening.

According to one aspect of the present invention, a method for manufacturing a can container includes: covering a can body with a can lid including a disk-shaped panel portion in which a score line is formed on an outer peripheral edge side, a flange portion seamed to the can body, a ring-shaped groove portion provided between the panel portion and the flange portion and protruding downward, and a tab that is provided in the panel portion, breaks the score line, and allows the panel portion to open along the score line; pressing an upper surface portion of the panel portion located on an outer side of the score line in a radial direction and above the score line with a knockout pad; and seaming the can lid pressed by the knockout pad and the can body.

The disclosure relates to a can lid for food or drink, the can lid including an end and a tab for opening a score formed on the end. The end and/or the tab includes an aluminum alloy containing: Mn: 0.5 mass % to 1.4 mass %, Mg: 2.0 mass % to 4.5 mass %, Si: 0.6 mass % or less, Fe: 0.8 mass % or less, Cu: 0.25 mass % or less, Cr: 0.10 mass % or less, Zn: 0.25 mass % or less, and Ti: 0.10 mass % or less. With this configuration, even if the end and/or the tab contains a recycled aluminum alloy made up of aluminum UBCs as a raw material, a can lid having such an end and/or tab that has properties required for a can lid, such as pressure resisting strength, can be provided.

An ecology stay-on tab beverage can end has a first curvilinear segment of frangible score severable to form a vent region and a pressure equalization port. A second curvilinear segment of frangible score has opposing terminal ends separated by a hinge segment of the center panel. The second curvilinear segment of frangible score is severable to form a pour opening. A lifting of a lift end of a tab actuates an opening sequence in which the first curvilinear segment of frangible score is severed causing the vent region and the pressure equalization port to form before the pour opening is completely formed.

An anti-opening container includes a first box and a second box. The first box includes a first body, a first box section and a first gripping section. The first box section is formed by the extension of the first body. The second box includes a second body, a second box section, a second gripping section, an extension section, and a fastener section. The second box section is formed by the extension of the second body. The fastener section is connected to the extension section via a perforated line. The fastener section is embedded in the first box section. When the first gripping section and the second gripping section are displaced in opposite directions, the perforated line breaks, and the first box section and the fastener section are separated from the second box section together to separate the first box and the second box.
