A method of packaging fluid or powdery products, in particular foodstuffs or beverages, in an essentially sterile manner in a packaging material in the form of a pouch of foil material having a filler opening closable by a closure cap, said method includes: providing a pouch whereby the closure cap can be placed in a first and second sealing position relative to the filler opening, whereby the closure cap is removable non-destructively from the filler opening in at least the first position; subjecting the interior of the empty substantially flat pouch having the closure cap in its first position to a germ-killing treatment; conveying the pouch having the closure cap in its first position and its interior already subjected to a germ-killing treatment to a filling plant; subjecting the exterior of the pouch having the closure cap in its first position to a germ-killing treatment; removing the closure cap from the pouch; filling the product into the pouch through the filler opening; and re-placing the closure cap on the filled pouch and closing the filler opening by moving the closure cap into its second position. A corresponding flexible pouch is also described.

A slit closure valve for container openings includes a membrane member of flexible material having an at least unidirectionally aligned slit-like outlet opening and a base member peripherally surrounding the membrane member and connected to the membrane member. The outlet opening is held in its closed position by the resilient properties of the material although it is adapted to be moved into its open position against the resilient bias force of the material by a predetermined differential positive pressure exerted on one side of the membrane member. A peripheral wall portion of the base member and an adjacent wall portion of the membrane member include therebetween an acute angle of less than 90&prime;. At least one further, substantially peripherally aligned slit-like passage opening held in its closed position by the resilient properties of the material is provided in the membrane wall portion near the base member, said passage opening being adapted to be moved into its unblocking position by a differential negative pressure exerted on the membrane member from the side thereof subjected to said predetermined differential positive pressure. The valve thereby enables the pressure between the interior of a container and its surroundings to be equalized thus assisting in the restoration of the container after its walls have been pressed-in manually for emptying the contents of the container.

In a screw thread arrangement for the angular positioning, in the circumferential direction, of a first component having a multiple-thread pattern screw thread relative to a second component having a complementary multiple-thread screw thread pattern, in particular for a threaded closure cap relative to a container member, wherein a first angular spacing of adjacent runouts when viewed in a circumferential direction differs from angular spacing of adjacent runouts . As an alternative the dimensions of at least one thread turn of each multiple-thread screw thread pattern is different from those of a second thread turn. By such measures, when configurations of the components are rotationally asymmetrical, the two parts are always positively brought into alignment when the one component has been firmly screwed onto the other.

A self-closing closure which can be integrated into a discharge opening of a container, cap part or the like, and includes an upper wall section ( ) containing a through opening ( ) and a sealing tappet ( ) which protrudes from an inner section ( ) of the closure and engages with the through opening from beneath the upper wall section. The configuration of the upper wall section ( ), at least on the upper surface thereof, can be adapted to the shape of the wall ( ) of the container such as to be flush therewith, and furthermore it is formed elastically deformable at at least an actuating portion ( &prime;) thereof so that the actuating portion is deformable in elastically concave manner by an external manual force exerted thereon. A conveying member ( ) is provided for converting the concave deformation of the actuating area into a relative movement between the sealing tappet ( ) and the through opening ( ) so as to release the latter whereby the contents of the container can be discharged.

A plastics weld pourer component having child-proof properties for attachment by welding to a container component of film-like plastics material, includes a tubular body portion defining a through passage having axially spaced ends. A plurality of welding ribs is formed integrally on the outer periphery of the body portion near one axial end of the through passage. Furthermore, a cap member is integrally formed on the body portion near the other axial end, said cap member sealing the through passage at one end. The cap member is attached to the body portion through a weakened portion which is adapted to break when a rotational force is exerted by hand on the cap member. The dimensions of the cap member relative to those of the body portion are made such that the cap member can be placed on the body portion for repeatedly sealing the through passage after it has been separated from the body portion. Furthermore, the cap member is also permanently attached in one-piece manner to the body portion through a meandering strap. A radially spaced ring element integrally formed with the cap member provides a flow passage between the cap member and the ring element, said flow passage acting as an emergency breathing passage should the cap member be accidentally swallowed.

A self sealing slit valve for closing off a container opening comprises a diaphragm part having a slit-shaped pour opening. The diaphragm part is made of a first thermoplastic elastomer material having resilient property, which is integrally formed to a base part made of a second thermoplastic material different from the first thermoplastic elastomer material. The slit valve according to the present invention is a molded part which is formed in a single operation by a two-component injection molding process.

A child-proof closure device for containers has an inner cap for securement on the container neck, and an outer cap rotatable on the inner cap between positions in which dispensing apertures in the caps are respectively aligned, to permit dispensing of the container contents, and covered, to prevent such dispensing. A square control projection on the inner cap is normally engaged with a star-shaped opening in the outer cap in one of positions angularly spaced by 45.degree. to prevent rotation of the outer cap, and can be disengaged for rotation by axial inward pressure to resiliently deform the inner cap. A ring of projections on the outer cap can engage in corresponding depressions or in the dispensing apertures of the inner cap.
