摘要

The kit (1) or ensemble comprises a closing cover in the form of a perforated blade (2), a capsule body (3) having a truncated arrangement with a lower base provided with perforations and an upper base provided with an annular edge in the form of flap, and a support sheet (4) with the cover having an auto-adhesive layer (20) at its lower part. The capsule body has an annular protuberance molded on a lower surface of its annular edge, where the protuberance extends from a proximity of the annular edge to an insertion zone that is provided in an external lateral surface of the capsule body. The kit (1) or ensemble comprises a closing cover in the form of a perforated blade (2), a capsule body (3) having a truncated arrangement with a lower base provided with perforations and an upper base provided with an annular edge in the form of flap, and a support sheet (4) with the closing cover having an auto-adhesive layer (20) at its lower part. The capsule body has an annular protuberance molded on a lower surface of its annular edge, where the protuberance extends from a proximity of the annular edge to an insertion zone that is provided in an external lateral surface of the capsule body and forms a pressure joint or a seal in the capsule body. The protuberance consists of a reinforcement cord to increase the stability and mechanical resistance of the capsule body. The support sheet has a smooth finish to facilitate the detachment of the closing cover, and is provided as an individual sheet or a roll having glued closing covers. The auto-adhesive layer is provided in the form of circular ring having a width, which is equal to a width of the annular edge of the capsule body.
