摘要:
The present invention relates to a process for blow molding a polyethylene container comprising the steps of: a) providing a solid preform made from a polyethylene material having a melt flow index from 0.01 to 10.0 g/10 minutes, wherein the preform comprises a neck region, side walls and a base region, and wherein the side walls between the neck region and the base region have substantially straight and parallel outer walls; b) reheating the preform so that the maximum temperature difference between the hottest and coldest regions of the side walls and the base region of the reheated preform is less than 4°C; c) transferring the reheated preform to a blow mould; d) stretching the preform at a pressure below 10 bars; and e) increasing the pressure within the reheated preform so as to cause the walls of the stretched preform to expand to the shape and dimensions inside the blow mould. A polyethylene container made according to the present invention preferably has a minimum wall thickness of the container of less than 200 micrometers, and a weight to volume ratio of the empty container of less than 50 grams per litre.

The process of the present invention comprises the steps of :
a) forming a bottle (3) with a handle (2), the handle (2) having opposing ends, wherein one end of the handle merges with the bottle in a merging region (4), and the other end of the handle is a free end (5); b) forming a flexible sleeve (6) essentially in the shape of a tube, the sleeve (6) having at least one cut-out region (7) which is defined on all sides by the sleeve (6), and wherein the profile of the cut-out region (7) is at least as big as the cross-sectional profile of the free end of the handle (5); c) opening the generally tubular sleeve (6) and disposing the open sleeve over the bottle (3); d) displacing the sleeve (6) relative to the bottle (3) so that the cut-out region (7) of the sleeve is adjacent to the free end of the handle (5); e) deforming the sleeve (6) so that the cut-out region (7) encompasses the free end of the handle (5); f) displacing the sleeve (6) relative to the bottle (3) so that the sleeve (6) generally surrounds the bottle (3), and so that the handle (2) is disposed through the cut-out region (7) of the sleeve; and g) shrinking the sleeve (6) to the outer surface of the bottle (3).

The invention relates to a bottle (1) having a base, a top part and sides, the bottle (1) comprising a handle (2) located on a side of the bottle, the bottle being shrink-sleeved, whereby the sleeve (3) covers the handle (2), the sleeve (3) comprising a cut-out allowing to grip the handle (2), the cut-out having a fringe maintained flush against the bottle (1).

The present invention relates to a roll-on applicator (10) which prevents leakage or spillage without the need of the cooperation of a cap. This container comprises a ball (3) and a flexible and resilient support means (4) for said ball. Said flexible and resilient support means is such to urge said ball against said dispensing opening, achieving a leak-tight engagement between said ball and said dispensing opening. Furthermore, said flexible and resilient support means can be resiliently deformed by an external force acting on said ball to disengage said leak-tight engagement between said ball and said dispensing opening, allowing said contained product to be spread by said ball.

The present invention relates to an apparatus for applying a sleeve to a bottle, wherein the bottle comprises a handle, the handle having opposing ends wherein one end of the handle merges with the bottle in a merging region and the other end of the handle is a free end. The apparatus comprises a sleeve applicator, and a means for inserting the free end of the handle through a hole in the sleeve. In a first embodiment the apparatus further comprising a transport means, the transport means being between the sleeve applicator and the means for inserting the free end of the handle through a hole in the sleeve. In a second embodiment the apparatus is an integrated machine which combines the application and the insertion processes.
