Abstract: Closures for container openings, which comprise: a tap (16); and a piston (4) capable of axial movement along a longitudinal axis (12) within the tap; wherein the tap has a product conduit (5) and a venting conduit (6) blockable by the axially movable piston are disclosed.

Abstract: A packaging system for bulk goods or material comprises a hollow polygonal blown plastic form or container for accommodating the material which is to be contained therein. A cardboard cover surrounds and is fixed to the hollow plastic form. The hollow plastic form has at least one outer edge indentation in a corner area, corresponding to a polygonal area of the cardboard cover which can be folded inside for locking or securement purposes, which is symmetrical to a corner fold line of the cardboard cover, and which is connected to the cardboard cover by at least one stamped line arranged perpendicular to the corner fold line and two fold lines forming a V-shape. The packaging system enables secure fastening between the hollow plastic form and the wrapper. To achieve this, the polygonal area of the cover is shaped as a square, and the V-shaped fold lines merge into two stamped lines culminating in a point.

Abstract: A plastic bottle, made of polyethylene (PE), polypropylene (PP), or poly(ethylene terephthalate) (PET), blown with a very thin overall wall thickness within the range 0.1 to 0.3 mm, includes a triangular or polygonal cross-section, the bottle being preferably surrounded by a supporting jacket. The bottle can be blown with a uniform wall thickness and adequate strength without the need for reinforcing ribs via walls formed by pressing them against the surface of a blow mold which has been worked at least in some areas by etching, form-cutting or eroding, having features with heights of 0.05 to 0.15 mm.

Abstract: A multicomponent product container includes two separate component compartments covered by a common pouring cap, individual pouring openings for the first and second components contained in the compartments, respectively, offset from one another relative to the longitudinal axis of the container and opening in the plane of an outer surface provided in said cap. The pouring openings are each juxtaposed in the pouring direction necessary to dispense the first and second components, by an individual pouring edge, which both rises beyond the outer surface of the cap, and projects beyond the associated pouring opening in the lateral or peripheral direction. Each pouring edge is shaped for providing in the tilted position of the container necessary for pouring via gravity said first and second components from said pouring openings, a sink formed in the region of the associated pouring opening.

Abstract: A dispensing storage container comprising a somewhat spherical housing forming a storage compartment for a supply of laundry treatment liquid and having an inlet/outlet portion, which may also be a removable cover portion. The inlet/outlet portion comprises a recessed groove, preferably annular, surrounded by elevated surface areas of the housing, and having inlet/outlet openings recessed at the base of the groove.

Abstract: Dispensing storage containers and assemblies of such containers secured over the conventional cup-like cap of a bottle designed to contain a supply of laundry treatment material. The dispensing storage containers have a shell housing, a closed base end, an open filling end and a cover including media transfer holes and means for securing it over the filling end of the container to disperse laundry treatment material from the container into the wash during use. The open filling end has a collar forming an opening sufficiently wide to receive and be secured over the cup-like bottle cap during periods of non-use, and the base end of the container preferably includes a flange means to which the cover can be secured on the assembly.

Abstract: A measuring cup closure for a container opening having a screwthread formed on its outside surface. The closure has a spout part which is placeable in the container opening, a pouring spout, and an outer ring formed integrally around the base of the spout part. The outer ring is adapted for surrounding the rim of the container opening from the inside to the outside of the container.The closure includes a measuring cup which is adapted to be screwed onto the container opening over the spout part wherein the aforementioned outer ring of the spout part has a screwthread for screwing the measuring cup thereto. The measuring cup is integrally formed with an encircling ring having an internal screwthread corresponding to the screwthread of the outer ring of the spout part and the screwthread of the container opening.

Abstract: A container or the like for cleaning preparations comprising a fused closure which consists of a stopper disposed in a closure hole of the container and made of a material which melts at a predetermined temperature and which releases the closure hole for the exit of product packaged in the container. A ring of which the thickness increases radially inwards towards the axis of the hole is integrally formed with the inner peripheral surface of the closure hole. The position and shape of the stopper are stabilized by a film applied by sealing to the outside of the closure hole. The walls of the container are flexible to accomodate changes in pressure inside the container.

Abstract: Processes and means for perfuming packaging containers wherein absorbable carrier materials, preferably in the form of a disc, are separately perfumed and then attached to an inner wall of the packaging container.
