BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates generally to a container arrangement.
More specifically, although not exclusively, the invention relates to a roll container arrangement which includes an openable roll container and which enables a web of material, preferably a paper web, to be pulled from the outside of the roll, preferably a roll of toilet paper.
U.S. Pat. No. 3,539,124 teaches a container arrangement which includes a rotation-svmmetrical basin and a pin located centrally on the bottom of the basin. The pin is intended to receive a roll of toilet paper having a central winding core made of cardboard or like material. Subsequent to placing the roll on the pin, a lid or cover having a centrally located peg is fitted onto the opposite end of the roll (i.e. the opposite end of the cardboard core). An annular gap is formed between the edge of the basin and the edge of the cover. The paper web is drawn off from the outer surface of the roll through said gap. The paper web is drawn from the roll by circulating around the outfeed gap and usually becomes twisted in the process.
SE-A-9203182.2 teaches an arrangement similar to the arrangement just described, although in this case the container basin is intended to be mounted on a wall so that the annular paper web outfeed gap faces downwards, and the paper roll is intended to rotate about a centre pin or peg in the basin. The container arrangement includes an end plate which defines the annular outfeed gap together with the edge of the basin and which is firmly connected to the bottom end of the pin. The circular end plate has a diameter which is greater than the original diameter of the roll, so as to prevent the web from sliding axially on the outer surface of the roll when web material, e.g. paper, is drawn from the container arrangement. This end plate thus has a guiding function and forms a firm seating for the bottom end surface of the roll and can be removed when needing to place a new roll in the roll container.
The arrangement taught by SE-A-9203182.2 has been found to be unusable because the material web tends to break or tear inside the basin. It has not been possible to solve this problem and consequently this known arrangement has not been marketed commercially.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a container arrangement which minimizes the tensile force that acts on a web of material when unrolled from the outside of a roll, particularly a paper roll, such as a toilet paper roll, rotatably mounted in the container, and with which the web is deflected around the edge of a web-deflecting guide member whose effective diameter is greater than the roll diameter, and with which said guide member is located between the roll and the web outfeed opening in the container arrangement.
This object is achieved with an arrangement according the claims.
A central feature of the inventive arrangement is that the guide member is arranged for rotation about an axis which is coaxial with the container. It is thus important to the invention that the actual guide member is able to rotate. The rotational bearings of the guide member may be disposed between the guide member and a roll guide pin, when such a pin is included. Alternatively, the guide member and a possible guide pin may be firmly connected together while the other end of the guide pin is rotatably connected to the container arrangement. The container arrangement will preferably include a guide pin which extends through the central bore of the paper roll and the guide pin will preferably have a diameter which is sufficiently small to enable the roll to rotate on the pin, at least in that case when the rotational bearing of the guide member is located between the pin and the guide member.
As a result of the substantial reduction in tensile forces on the web as the web is pulled from the roll, the container can be configured with a centrally positioned, small outfeed hole in one end wall of the generally cylindrical container, this end wall preferably b
