Definitions

  • the present invention relates to a device for generating at least partial vacuum in bags for packaging clothes or the like.
  • Bags are commercially available which are constituted by two walls made of heat-sealing synthetic material, which are mutually connected so as to form a receptacle that can be accessed from a mouth of the bag and is designed to contain, for example, clothes, blankets, duvets and the like.
  • closure of the inlet is ensured by means of various kinds of device.
  • One of these devices consists of a cylindrical element, around which the rim of the mouth of the bag is wrapped, and of a closure element, which has a surface that is complementary to the lateral surface of the cylindrical element and is designed to be coupled to the cylindrical element in order to keep the rim of the mouth locked between the two complementary surfaces so as to close it.
  • Bags which have, at one of the two walls, a valve for aspirating the air contained therein, in order to reduce the volume of the items of clothing contained in the bag.
  • the valve is suitable to be connected to the suction connector of a conventional vacuum cleaner.
  • valve on the bag constitutes a very awkward bulk, especially in the very frequent case in which a plurality of bags are to be stacked one on top of the other.
  • valve is a critical point for maintaining vacuum over time.
  • the aim of the present invention is to eliminate the drawbacks noted above by providing a device for generating at least partial vacuum in bags for packaging clothes or the like, which allows to extract air from the bags in a practical manner.
  • an object of the present invention is to provide a device for generating at least partial vacuum in bags for packaging clothes or the like that allows to close the bags hermetically.
  • Another object of the invention is to provide a device for generating at least partial vacuum in bags for packaging clothes or the like that allows to use bags that do not have a suction valve.
  • a further object of the present invention is to provide a device for generating at least partial vacuum in bags for packaging clothes or the like that thanks to its particular constructive characteristics is capable of giving the greatest assurances of reliability and safety in use.
  • a still further object of the present invention is to provide a device for generating at least partial vacuum in bags for packaging clothes or the like that has a very simple structure, is easy to use, and has a competitive production cost.
  • a device for generating at least partial vacuum in bags for packaging clothes or the like characterized in that it comprises a box-like body that forms a suction chamber designed to accommodate at least one portion of a mouth of a bag for packaging clothes or the like, means for providing at least partial airtightness acting between said bag and said box-like body, said suction chamber having an air suction intake that can be connected to air suction means, said device comprising heat-sealing means that act on a region of said bag that is interposed between said at least one portion of said mouth and the clothes or the like contained within said bag.
  • the device for generating at least partial vacuum in bags for packaging clothes or the like comprises a box-like body 2, which forms internally a suction chamber that is designed to accommodate at least one portion of an inlet or mouth of a bag 3 adapted to package clothes 4 or the like.
  • means for providing at least partial airtightness are provided and act between the bag 3 and the box-like body 2.
  • the suction chamber has an air suction intake 18, which is conveniently surrounded by a sealing element 18a and can be connected to air suction means 5.
  • the air suction means 5 are constituted by a vacuum cleaner provided with a suction hose 6 that ends with a connector 7 that can be connected to the suction intake 18 of the suction chamber and can engage hermetically the sealing element 18a, which is advantageously capable of adapting to the various diameters that the connector 7 can have.
  • the device according to the invention further comprises heat-sealing means 8, which are adapted to act on a region 9 of the bag 3 that is interposed between the portion of the mouth of the bag 3 that engages the suction chamber and the clothes 4 contained in said bag 3.
  • the box-like body 2 is formed by two parts 2a and 2b, which are associated to each other and can move with respect to each other to pass from an open condition, in which they allow to arrange at least one portion of the mouth of the bag 3 in the suction chamber, to a closed active condition, in which the sealing means form an at least partial seal between the outer surface of the bag 3 and the two parts 2a and 2b, so as to isolate the suction chamber from the outside.
  • such means comprise, at one of the two parts 2a and 2b, for example at the part 2a, heating means which, according to an example of embodiment, are constituted by an electric resistor that is controlled by a control circuit provided with an activation button 10.
  • the heating means are also provided with a protective element 11 that covers the electric resistor.
  • the heat-sealing means 8 are completed by an insulating element 12, which is supported by the part 2b and is designed to face the protective element 11 when the two parts 2a and 2b are placed in their closed active condition.
  • the protective element 11 is constituted by a plate-like element made of Teflon, while the insulating element 12 can be formed advantageously by a plate-like element made of silicone material.
  • At least one of the two parts 2a and 2b has a recess 13, which forms the suction chamber in cooperation with a portion of the other part that faces it in the closed active condition.
  • both parts 2a and 2b are provided, in matching positions, with a respective recess 13, which, when the two parts 2a and 2b are in the closed active position, forms a corresponding portion of the suction chamber.
  • sealing gasket 14 which constitutes such sealing means.
  • the two parts 2a and 2b are constituted by two elongated elements, which are pivoted to each other, for example at one of their ends, about a rotation axis that is formed by a pivot 100 that is substantially perpendicular to their longitudinal extension.
  • the parts 2a and 2b have, at their end that lies opposite the pivoting end, retention means 15, which are designed to keep the two parts 2a and 2b arranged so that they face each other when they are in the closed active condition and are constituted by a tooth 16 that is supported for example by the part 2b and can engage detachably an abutment profile formed on the part 2a.
  • the mouth of the bag 3 is arranged within one of the recesses 13, so that the clothes 4 are arranged on the opposite side of the mouth with respect to the heat-sealing means 8 (as shown in Figure 3).
  • the parts 2a and 2b are placed in the closed active condition, and as shown in Figure 4 the intake 7 of the vacuum cleaner is connected to the suction intake 18 of the suction chamber and engaged, on its outer lateral surface, with the sealing element 18a in order to extract the air from the suction chamber and accordingly from the inside of the bag 3.
  • the heat-sealing means 8 are activated by way of the activation button 10 and seal the region 9 of the bag 3 that is interposed between the insulating element 12 and the protective element 11.
  • the bag 3 at least proximate to its mouth and at least up to the region 9, with means for spacing its internal surfaces that are suitable to form a plurality of air suction channels.
  • spacer means can be constituted by an embossed internal surface of the bag 3 or by a plate-like element that is interposed between the internal surfaces of the walls of the bag 3 and has a substantially undulated configuration.
  • a bag 3 of the concertina type or the user can directly form the creases in the region that is engaged by the device according to the invention, so as to form channels through which the air to be aspirated can flow.
  • Another possible solution is to insert, through the mouth of the bag 3, at least one tubular element, which can be arranged so that one end is connected to a suction chamber and the other end lies within the internal portion of the bag 3 arranged between the region 9 and the clothes 4.
  • the bag must be made, at least at its internal surfaces, of a heat-sealing material, such as for example polypropylene or polyethylene.
  • the two parts 2a and 2b can be constituted by two elongated elements that are associated to each other on a long side and so that they can rotate about a rotation axis that is substantially parallel to their longitudinal extension.
  • the materials used may be any according to requirements.
