摘要:
The present invention relates to a flexible container containing a liquid product, wherein the flexible container (2) comprises a closure having an inner end and an outer end, the closure being fixed through the wall of the flexible container (2) such that the inner end of the closure lies within the flexible container (2) and is in contact with the liquid product, and the outer end of the closure lies outside of the flexible container, wherein the closure has an open position and a closed position, and wherein the outer end of the closure is connected to a self-sealing valve (30) which opens when the closure is in the open position and when pressure is applied to the liquid product within the flexible container, and which closes when the pressure is released. In another aspect the invention relates to a process of making a liquid-filled, flexible container.

The present invention relates to a shipping unit (30) comprising a plurality of lightweight plastic containers (1), the containers being held in position relative to each other by an outer supporting layer (31), the outer supporting layer (31) being essentially a film in tension. Substantially all of the containers (1) comprise a base portion (2), a top portion (3), a side wall (5) and optionally a handle (10), wherein at least two opposing regions (6, 6') of the side wall (5) are joined together to form a rigidifying portion (7) of the container other than the optional handle (10).

A process for manufacturing a filled aerosol container, the aerosol container containing a propellant and a product, the propellant being soluble in the product, the propellant being non liquefiable, the process comprising a water bath step, the water bath step consisting in immersing the filled aerosol container in water. The water bath test is such that the aerosol container has an internal pressure above its equilibrium pressure prior to and while being immersed in water, in order to detect leakage more rapidly.

The invention relates to a wrapped bundle (20) comprising one or more rows of plastic containers (1) and an outer wrapping layer (16), the or each row comprising a container at each end of the row, each of the end containers comprising a handle (10), the handle being asymmetrically located on the container to provide a first side of each container which contains the handle, and a second, opposing, side of each container which does not contain the handle, and wherein the first side is more rigid than the second side, whereby the first side of the end containers is directed towards the outside of the wrapped bundle (20), and the second side of the end containers is directed towards the middle of the row; or the handles (10) of adjacent containers (1) are directed towards opposite sides of the wrapped bundle (25).
摘要:
The present invention concerns a foam having a bulk density of less than 250 g/l; the foam having a stability in air of at least 15 seconds (and preferably at least 30 seconds), the stability being defined as the time for the foam to collapse to half its volume when measured in a 111 mm internal diameter and 62 mm internal height glass beaker; wherein the foam has a stability on water at 20°C of less than 2 hours, the stability on water being defined as the time taken for a 150 ml foam mass on the surface of 450 ml distilled water in a 111 mm internal diameter and 62 mm internal height glass beaker, to collapse to reveal a 2 cm diameter area of the water surface which is substantially free from foam.

The present invention relates to a process for blow-molding a container, the container comprising a handle, whereby the process comprises the steps of:
(i) introducing a thermoplastic preform (2) into a mold cavity (6) and stretching the preform (2) with a stretch rod (3); (ii) increasing the pressure within the preform (2) so that the preform (2) expands within the mold cavity (6); (iii) displacing at least one moving mold section within the mold and which deforms the thermoplastic material;
wherein the displacement of the moving section is in a direction which is substantially parallel to the direction of movement of the stretch rod (3).

The present invention relates to process for forming a container by stretching and blow-molding a preform within a mold cavity comprising the steps of:
(i) introducing a preform into the mold cavity and stretching the preform with a stretch rod; (ii) increasing the pressure within the preform so that the preform expands within the mold cavity in a blowing step; (iii) at least one inwardly moving mold section within the mold cavity so that the expanding preform is deformed by the inwardly moving mold section;
wherein the glass transition temperature (Tg) of the preform material is at least 10°C below the temperature of the walls of the mold cavity. The present invention further relates to a stretch blow molded container comprising walls of a thermoplastic polyolefin, the thermoplastic polyolefin having a glass transition temperature of less than 30°C and wherein the container has a degree of asymmetry of at least 1.5.

Self-standing pouches are disclosed which are made of a flexible material, which comprise a contained goods and which are inflated during manufacture, before they are closed. Inflated pouches are thus obtained which are made of a flexible material and which are yet substantially more rigid than similar but non-inflated pouches. The pouches thus obtained stand upright in a stable manner and are less prone to folding. In a preferred embodiment, the pouches herein comprise a cut-opening region, and a spontaneous pouring spout is formed as the cut-open region is cut off.

The present invention relates to a flexible multiple compartment pouch, preferably capable of being used, when comprising compositions, to refill a multiple compartment durable container. In a preferred embodiment, the multiple compartment pouch comprises a gripping means. In another preferred embodiment, the multiple compartment pouch comprises at least one gusset. In yet another preferred embodiment, the multiple compartment pouch comprises at least a first and second compartment wherein the first compartment comprises a first composition and the second compartment comprises a second composition and wherein the first and second compositions are incompatible.
