A cap assembly includes a base cap, a chemical resistant sheet, and a closure assembly. The closure assembly is configured for carrying the chemical resistant sheet. The closure assembly is mounted in the base cap. The base cap and the closure assembly together define a central cap assembly aperture therethrough.

A cap assembly comprising a body, a sealing membrane and a retaining ring. An opening is provided through the body and includes a recessed circumferential channel and a membrane engaging flange positioned proximate the recessed circumferential channel. The sealing membrane covers the opening and includes a body engaging flange and a pierceable surface. The retaining ring is positioned with the sealing membrane engagement surface in overlying engagement with the sealing membrane. Extension of the tab into the recessed circumferential channel of the body releasably maintains the overlying engagement and biases the retaining ring against the membrane. The inner wall structure of the retaining ring extends radially inward beyond the membrane engaging flange of the sealing membrane, to, in turn, protect the membrane.

A closure for a pharmaceutical vial. The closure comprises an aluminum foil with an inductively meltable adhesive, an elastic seal, and a cap. The cap has an opening through which a perforating cannula can be inserted.

A tap is described for delivering liquids from a container: including: a main body to be placed at the delivery end of the container; a valve inserted between a lower fastening body and the main body, which includes slits to ensure the air-tightness allowing liquids to pass only when opening the tap; the lower fastening body to be placed on the delivery end of the container; and an upper plug placed over the main body; the main body includes a tamper evident warranty ring integrated and removable when first opening the tap; and the upper plug is assembled on the main body and anchored to the warranty ring integrated in the main body.

An anti-spurt device, for application in a closure of a container with a cap and a ring with teeth for cutting a sealing membrane. The anti-spurt device may comprise a tube that automatically unfolds from a folded position and may be connected with the cutting ring. In the folded or loaded position, the tube may be outside of the sealing membrane and with the breakage of the membrane, it may be inserted and automatically unfolded in the inside of the container. In a second main embodiment, the need for a cutting ring and membrane may be eliminated, and the tube may be installed on a carriage held by a hook that is released with the opening of the cap.

A closure having a base with a piercable part, defined by a sidewall extending transversally with respect to the base and a bottom thereby creating an indent therein, the sidewall and/or bottom provided with several lines of weakened material strength, wherein the lines divide the sidewall and/or bottom in several wedge formed parts.
