Abstract:
1. Draining device for a package for a liquid material, wherein the draining device comprises: a housing part; and a draining part which is arranged movable in relation to the housing part, wherein the draining part is attached articulated to the housing part around an axis in a joint, wherein the housing part comprises a first channel with an inlet which ends towards the inside of the package during draining of the contents and an outlet which ends in the section surface between the housing part and the draining part, and wherein the draining part comprises a second channel with an inlet which ends in the section surface between the housing part and the draining part and an outlet which ends on the outside of the package, wherein the housing part of the draining device comprises an attachment surface defining a plane along which the housing part is arranged to be attached on the outside of a wall of the package, the plane being vertical in the normal draining position of the package, when the package is standing with its horizontal bottom on a horizontal surface, and the draining part being arranged with at least one puncturing device in its end opposite to the outlet, which puncturing device is arranged to puncture the wall of the package so that at least one passage is formed in the wall of the package through which passage liquid material located in the package may be made to flow out through the draining part to the outside of the package whereby the package may be emptied via the draining device, wherein the housing and the plane defined by the attachment surface define a cavity, wherein the puncturing device is arranged in the cavity when the channel in the draining part is directed upwards from the axis, wherein the axis is horizontal and the outlet of the channel in the housing part is arranged to change from not being in contact with the inlet of the channel in the draining part to abut the inlet of the channel in the draining part in a position where the channel in the draining part in the normal draining position of the package inclines downwards in the direction towards its outlet which ends outside the package, in which position the puncturing device protrudes through the plane defined by the attachment surface, such that the puncturing device widens the passage to enable a larger flow through the passage when the draining part is in the normal draining position, and where the outlet of the channel in the housing part and the inlet of the channel in the draining part further are arranged to abut each other to an increasing extent as the end of the draining part being at a distance from the joint is moved further in a direction downwards, and the outlet of the channel in the housing part is arranged displaced in a direction upwards in relation to the inlet of the channel in the position where the channel in the draining part is in a horizontal position.
