The packaging box provided by the present disclosure is conducive to storage, transport, and cutting the vacuum bag rolls, meeting the requirements of the user for using vacuum bags.

A foil dispensing device for on demand dispensing of sections of foil of a selectable length includes a housing comprising a lid that is hingedly engaged to a box so that the lid is positioned to selectively close an open top of the box. A motor is engaged to and positioned the box. A spindle is positionable in box to operationally engage the spindle to the motor. A roll of foil is positioned around spindle so that a free end of the roll of extends into a slot positioned in the housing. A motion sensor engaged to the housing and operationally engaged to the motor is actuated by motion of a hand of a user to signal the motor to rotate the spindle to dispense a section of the foil through the slot. A cutter positioned by the slot cuts the foil to separate the section from the roll.

There is provided an image recording apparatus having a housing having a front wall and a rear wall, and a right wall and a left wall defining an internal space of the housing, a sheet roll holder configured to hold a sheet roll, a supporting member configured to support the sheet roll, the supporting member extending in an axial direction of the sheet roll and being supported by the sheet roll holder, a sheet conveyer arranged in an internal space of the housing, the sheet conveyer being configured to convey a sheet unwound from the sheet roll, and a recording device configured to record an image on the sheet unwound from the sheet roll and conveyed by the sheet conveyer. The sheet roll holder is configured to be slidable with respect to the housing so as to be detachable from and attachable to the housing.

Refill for a dispenser, with a material web wound to form a roll and at least one substantially axially adjustable bearing journal. The at least one substantially axially adjustable bearing journal is adjustable substantially axially outwards away from the roll starting from a defined inner end position in which it protrudes axially beyond the roll. A bearing unit for such a refill, and a dispenser for housing the refill and dispensing the material web are also provided.
