Abstract

An internal-expansion sealing cover for round-mouth cans belongs to the technical field of manufacturing of daily appliances, and particularly relates to the technology of design and manufacturing of covers of sealed cans which are used for storing and preserving. The internal-expansion sealing cover is characterized in that a round expansion hoop is embedded in an inner cover and formed by connecting four quarter expansion hoop units by elastic split rings, each expansion hoop unit consists of a large-diameter quarter ring and a corresponding small-diameter quarter ring which are connected by five straight ribs, an involute surface which is expanded gradually is attached to the inner circle of the small-diameter quarter ring, two ends of the involute surface are provided with limit bars, support columns connected with a knob are butted against the involute surface, and a silicon rubber strip closely fit with the inner edge of the mouth of a round-mouth can is attached to the outer edges of the expansion loop units closely. The internal-expansion sealing cover has the advantages that the internal-expansion sealing cover has excellent sealing effect to round mouths, is novel in sealing manner and can be used for various round-mouth cans.
