In the preferred scheme, still be equipped with annular cutting line on the backing layer, annular cutting line with the bow-shaped tear line diameter is the same and concentric setting, the backing layer divide into by annular cutting line and press seal outer loop and inner circle portion once more, the bow-shaped portion is in the inner circle portion. Through this kind of setting, when the material in the container is toppled down gradually and be difficult for pouring, the user can tear the other regions of inner circle portion together through annular cutting line, forms complete full opening. Typically, after tearing the seal, if the contents of the container are not used up at one time, the seal is deteriorated after the cap is re-applied. Resealing may also be performed by providing a resealing outer ring.
In a further preferred scheme, a plurality of adhesion points are arranged between the arched part and the re-press-sealed outer ring, between the arched part and other areas of the inner ring, and between the re-press-sealed outer ring and the inner ring.
In a preferred scheme, a plurality of protruding points are arranged on the lower surface of the handle part. Through setting up a plurality of bumps at the lower surface of handle portion for the combination of handle portion and aluminium layer is loose, breaks out the handle portion off with fingers and thumb and pulls up from the aluminium layer more easily.
In a preferred embodiment, the adhesive layer is directly laminated on the lower surface of the aluminum layer.
In a preferred embodiment, the backing layer is laminated on the upper surface of the aluminum layer by an adhesive layer.
In a preferred embodiment, the backing layer includes a PE foam board and a PE film, and the PE film is laminated on the upper surface of the PE foam board. The backing layer may also be a plastic film, cardboard, foam board or plastic board.
The utility model has the beneficial effects that: the semi-tearing sealing gasket can keep the sealing gasket flat after sealing, can open a semi-opening with a neat boundary when uncovering, and is easier to tear the aluminum layer.
