Abstract:
A closure assembly is provided that includes an outer cap with a skirt dimensioned to telescope over the open top end of the tube. An annular shoulder extends inwardly from the top end of the skirt and includes an aperture through which a needle may be directed. A laminated seal is bonded to the bottom surface of the annular shoulder of the outer cap and extends continuously across the aperture in the annular shoulder. A stopper is secured on the bottom surface of the annular seal and is dimensioned for sealing engagement in the open top of the tube. Outer circumferential portions of the bottom surface of the laminated seal between the skirt and the stopper are bonded to the open top end of the tube. The bond between the closure and the laminated seal is stronger than the bond between the tube and the laminated seal. Thus, the closure assembly retains its structural integrity after opening of the tube and can be used to reseal the tube.
Abstract:
A container, particularly for medical preparations, comprises a container body (2) with an integral closure portion (16) and a cap (6) provided over the closure portion. The container body is provided with a frangible portion for removal of the integral closure. The cap is provided with an internal spike (28) which penetrates the closure portion (16) when the cap (6) is screwed towards the container body (2). A Luer connector (26) is provided on the cap (6) and accesses the container contents via a passage through the spike (28).
Abstract:
The invention relates to a resealable plastic packaging container (1) consisting of a tray (2) and a lid film (3) which in the sealing area (4) is sealed to the tray (2) such that it can be at least partly peeled back. The plastic packaging container comprises at least one hook and loop closure (9, 10, 11) whose two complementary parts (9′, 10′, 11′) are arranged opposite each other on the tray (2) and lid film (3), respectively, and by means of which the plastic packaging container can be resealed after the peel-back seal has been opened.
Abstract:
A liquid chromatography seal capable of withstanding pressures in excess of 8000 to 10,000 psi utilizing an annular ring disposed upon either the seal or the seal seating surface. The annular ring is triangular in cross section. The triangular cross section forms three seals. The first seal is the innermost face of the triangular cross section, the third is the outermost face, and the second is the angle between the first and third. The structure of the seal enables the column to be leak-free even with a minimum of torque applied to the fasteners. Another important aspect of the seal is that it eliminates the need for a disperser frit since the seal itself acts as to disperse liquid to the frit.
Abstract:
A vial closure device, a sample vial incorporating such a vial closure device, and certain methods of using such a vial and closure device. The vial and closure device are intended to contain a gaseous sample or a headspace gas present above a liquid or solid material, so that the gaseous sample or headspace gas can be conveniently analysed, typically by means of an autosampler connected to an analytical instrument such as a mass spectrometer. Mass spectrometric methods of determining the isotopic composition of hydrogen and oxygen comprised in aqueous samples contained in vials fitted with such closure devices are disclosed. The vial closure device comprises a hollow body member locatable in the mouth of a vial, and a first seal for making a substantially gas-tight seal between the exterior of said hollow body member and said vial. The hollow body member comprises an aperture and an aperture closing means for closing said aperture when required, and a second seal, through which a gas sampling means may be inserted. The aperture closing means is operable to open the aperture by the insertion of a gas sampling means through the second seal and is operable to close the aperture when the gas sampling means is withdrawn.
Abstract:
A container having a closure comprising a closure wall having a puncturable region in communication with the interior of the vessel, and having on an inwardly facing region of the closure wall a desiccant material separated from the interior of the vessel by a semi-permeable membrane which permits transmission of water vapor therethrough but is substantially impermeable to liquid water.
Abstract:
A sealing element for sealing a container includes a cap having a top with an opening therein in combination with a septum. The septum includes an elastomer in direct physical contact with an interior surface of the cap. The septum occludes the opening in the top. There is no layer of adhesive or plastic material between the elastomer and the interior surface of the cap. The cap may be made of plastic or metal. Also provided is a method of directly bonding an elastomer, such as silicone rubber, to a plastic or metal.
