ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an element for adjusting the outlet width in dispensers of paper towels, in particular but not necessarily of the type in which the paper towels are mutually interleaved or intercalated (i.e. of the C-shaped type) and stacked in a dispenser with a bottom outlet.
It is known that in dispensers of paper towels of the above-mentioned type, but also of towels cut from a continuous roll, the dispenser outlet has a well definite cross-section corresponding to a certain width of the paper towel to be manually pulled out through the outlet. Clearly you can not be sure to use always the same type of paper, whose size can change in width, e.g. if you change supplier, thus making the operation of the dispenser less than optimal. In fact, if a paper having a width significantly smaller than the dispenser outlet width is used, the removal of single paper sheets at each manual pulling action performed by the user can no longer be guaranteed.
This drawback has been overcome until now by providing templates of different sizes to be applied to the dispenser outlet, so as to change the shape and size of its cross-section, but it is clearly unpractical to have a template for each different size of the paper sheets used in the dispenser.
BRIEF SUMMARY OF THE INVENTION
Therefore the object of the present invention is to provide, for any dispenser, a pair of adjusting elements which can take different positions along the dispenser outlet thus changing the width thereof according to the size of the paper sheets in use.
It should be noted that such adjusting elements can be useful also in dispensers of paper towels cut from a continuous roll, by forming a lateral guide which better follows the sheet during its unwinding and removal from the dispenser, regardless of the way in which this takes place.
This object is achieved through an adjusting element, in the specular right and left versions, having the characteristics cited in claim
