Abstract
An adapter element configured for insertion inside the core of a paper roll to be applied to the support shaft of a dispenser includes an external annular wall adapted for insertion into the core of the paper roll with a predetermined degree of mechanical interference; an axial channel delimited by an annular wall arranged internally to the external annular wall; and first engaging elements configured for releasable engagement to second engaging elements belonging to the support shaft of the dispenser so that, in use, a portion of the end of the support shaft is insertable into the axial channel of the adapter element. A dispenser is also disclosed having the support shaft adaptable for engagement with the adapter element.
Claims21
An adapter element (11) configured for being insertable inside a core (110) of a paper roll (100) to be applied to a support shaft (7, 8, 9) of a dispenser (10) for paper rolls, said adapter element comprising:
- an external annular wall (12) configured for being inserted into the core (110) of the paper roll with a predetermined degree of mechanical interference;
- and
- an axial channel (14c) delimited by an annular wall (14, 14′) arranged internally to the external annular wall (12) and comprising first engaging elements (15a) configured for being engaged in releasable manner to second engaging elements (15b) belonging to said support shaft (7, 8, 9) of the dispenser so that, in use, an end portion (7s) of said support shaft (7, 8, 9) can be engaged in said axial channel (14c) of the adapter element (11),
- wherein said first engaging elements (15a) are configured to be engaged to said second engaging elements (15b), so that said adapter element (11) is rotatable in idle manner around said support shaft (7, 8, 9) to which said adapter element (11) is engaged in use.
An assembly for constraining a paper roll fitted with a core to a dispenser, said assembly comprising:
- an adapter element (11);
- and
- a support shaft (7, 8, 9), said adapter element and said support shaft being configured for being insertable inside said core (110) of said paper roll (100) so as to engage to each other in a releasable manner;
- said adapter element (11) comprising an external annular wall (12) configured for being inserted into the core (110) of the paper roll with a predetermined degree of mechanical interference, said support shaft being configured for being inserted into the core of the paper roll, so that the paper roll unobstructedly rotates around said support shaft, said adapter element (11) further comprising an axial channel (14c) delimited by an annular wall (14, 14′) arranged internally to the external annular wall (12) and comprising first engaging elements (15a) engaging in a releasable manner to second engaging elements (15b) belonging to said support shaft (7, 8, 9) so that, in use, a portion of an end (7s) of said support shaft (7, 8, 9) can be engaged in said axial channel (14c) of the adapter element (11), said first engaging elements (15a) being configured so as to be constrained to said second engaging elements (15b) so that said adapter element (11) is rotatable in idle manner around said support shaft (7, 8, 9).
