Definitions

  • the present invention relates, in general, stretch film dispensers intended to be directly used by a human operator.
  • the invention relates to a stretch film dispenser, comprising a mandrel cylindrical hollow, a roll of stretch film, and first and second manipulation organs, the mandrel delimiting an internal volume and presenting first and second ends, an external face and an axis of revolution, the roller being wound on the external face of the mandrel, and the first and second organs of manipulation being engaged in the internal volume of the chuck, first and second respectively ends of this mandrel, these members being susceptible to be simultaneously hand-held by an operator to allow the film to be rolled out by application, on the film in progress, of a controlled traction causing a rotation of the mandrel.
  • a device of this type is for example at least partially known from patent EP 0 200 662, which describes a reusable handling device, intended for be implemented in such a device.
  • the present invention which is in this context, precisely aims to alleviate the problems previously mentioned.
  • the device of the invention by elsewhere conforms to the generic definition given by it the preamble above, is essentially characterized in that at least the first end of the mandrel does protruding from the roller, and in that the first member of manipulation basically consists of a first cylindrical sleeve folded back on itself and offering to the operator's hand only a surface of slip without roughness, this first sleeve comprising a hollow internal cylindrical part, threaded in the internal volume of the mandrel, a cylindrical part external hollow, at least partially covering the face external of the first end of the mandrel which makes protrusion from the roller, and a connection surface connecting the internal and external parts of the first sleeve and frontally covering the first end of the mandrel.
  • the device of the invention thus designed is such that at least the first manipulation member is mounted, both from the outset and permanently, on the corresponding end of the mandrel, this member has no need to present the axial cutouts which are provided on the known removable handling members, and whose contact with sliding and pressure on the operator's hand causes irritation and burns.
  • the internal cylindrical part of the first sleeve can just be force-fitted in the first end of the mandrel.
  • connection surface of the first sleeve preferably has a rounded external profile.
  • the first sleeve can be made of a material injectable polymer, such as polypropylene, mandrel being generally made of cardboard.
  • the cylindrical part internal hollow of this first manipulation organ can present, at a distance from the connection surface, a tapered end likely to be more easily engaged in the internal volume of the mandrel.
  • the second manipulator is basically constituted by a second sleeve, which is shaped and secured to the mandrel like the first sleeve.
  • the invention relates a stretch film dispenser, which includes a mandrel 1, a roller 2 formed from a stretch film 20, and handling devices 3 and 4.
  • the mandrel 1 is constituted by a hollow cylinder, generally of cardboard, which extends along an axis of revolution X, and which delimits, between its two ends 11 and 12, an internal volume 10.
  • Roll 2 is wound on the middle part of external face 100 of the mandrel 1, while the organs of handling 3 and 4 are engaged in the internal volume 10 of this mandrel, at the respective ends 11 and 12 of this last.
  • organs 3 and 4 are designed to be simultaneously hand-held by the user of the film dispenser that the device of the invention.
  • the user adheres the free end of the film 20 to an object to be wrap and move roller 2 relative to this object by holding the mandrel 1 through the handling devices 3 and 4.
  • controlled traction T is applied to the film 20 during unwinding and causes the rotation of the mandrel 1, this traction and this rotation being controlled by the tightening that the user exercises by hand on at least one of the handling devices 3 and 4.
  • ends 11 and 12 of the mandrel 1 protrude out of the roller 2, and the handling members 3 and 4 are essentially constituted by cylindrical sleeves each of which is folded in on itself and does not offer by hand of the operator that a sliding surface devoid of roughness.
  • Each of the sleeves 3 and 4 for example made of an injectable polymer material such as polypropylene, comprises on the one hand an internal cylindrical part hollow, such as 31 and 41, which is threaded into the internal volume 10 of the mandrel.
  • Each of the sleeves 3 and 4 further comprises a hollow external cylindrical part, such as 32 and 42, covering at least part of the external face 100 with the corresponding end 11 and 12 of the mandrel which makes protrusion from the roller 2.
  • each of the sleeves 3 and 4 finally includes a connection surface, such as 33 and 43, which connects internal and external parts such as 31, 32 and 41, 42 of this sleeve 3 and 4, and which covers frontally the corresponding end 11 and 12 of the mandrel, this connection surface 33, 43, preferably having a rounded external profile.
  • the part internal cylindrical, such as 31 and 41, of each of sleeves 3 and 4 advantageously has one end conical, such as 310 and 410, engaged in the volume internal 10 of the mandrel 1, and force-fitted into the corresponding end, 11 and 12, of this mandrel.
  • sleeves 3 and 4 can easily be clamped at least between the thumb and the user's index finger, the thumb being applied to the external part 32, 42, and the index, possibly helped by major, being engaged in the internal part 31, 41.
