Definitions

  • the invention multipurpose die-cut bag, relates to a multipurpose die-cut bag, referring to a plastic bag, preferably recycled, of the type made up of two rectangular sheets with a die-cut, close to the opening, that serves as a handle, further having a self-closing strap, whereby, in addition to the uses that it can be given as a reusable bag with handles to transport products, it allows the lacing of the strap to be closed at the opening thereof, for example, to use it as a garbage bag in one last use of the bag.
  • the field of application of the present invention falls within the sector of the industry dedicated to the manufacture of bags, particularly plastic bags or bags made of a similar material with a handle to transport products, at the same time covering the field of garbage bags with a self-closing strap.
  • Plastic bags or bags made of similar materials, whether recycled or biodegradable or not, are known on the market, said bags having a handle defined by an oval-shaped hole die cut in the material close to the opening, known in the sector as die-cut bags. Bags of this type, with a low manufacturing cost due to their simplicity, are currently widely used, especially in the retail and supermarket sectors. However, their use is only intended for the transport of the acquired product and, depending on whether the material withstands it, its subsequent reuse also to transport other products or objects, such as in the case of recycled plastic bags, in that the bag has a high number of reuses, preserving its original characteristics and properties.
  • the objective of the present invention is, therefore, the development of an improved plastic bag with a die-cut handle which further allows its use by closing the opening with a self-closing strap.
  • the bag has a multipurpose use, serving both to transport products from the shop to the home, to reuse it to carry any product or object that fits in it and one last use as a correctly closed garbage bag.
  • the object of the present invention is a multipurpose die-cut bag according to claim 1.
  • the invention proposes a bag, preferably made of plastic material, and more preferably made of recycled plastic material, of the type comprising two side walls preferably joined together by their two lateral sides and their lower side, while their upper side determines the access opening to the interior of the bag, opposite the lower side that forms the bottom of said bag.
  • the sides of the bag are preferably joined together done by means of welding, in particular heat-welding.
  • Each of the two walls close to said opening have a die-cut hole in the form of a handle to hold the bag by hand.
  • Said die-cut hole has an upper side of the hole closer to the opening, a lower side of the hole closer to the bottom of the bag, and two lateral sides of the hole that join the upper side and the lower side of the die-cut hole.
  • the bag has a strap located between the upper side of the die-cut hole of each side wall and the opening of the bag, the strap being accessible from said upper side of the die-cut hole so that when it is pulled, it closes the bag.
  • the strap is accessible from the outside of the bag, that is, from outside the opening, or from the inside of the bag, that is, from inside the opening.
  • the bag preferably comprises at least above the die-cut hole of each side wall, a double wall or cuff that determines a tube connected to the outside through the upper side of the die-cut hole.
  • a strap that remains concealed inside each tube. Said strap is joined to the welds between the lateral sides of both side walls.
  • each strap located above each die-cut is accessible through the upper side of each of the two die-cut holes.
  • each strap is accessed through the die-cut hole and pulled, extracting it through the die-cut hole, bringing the sides where the ends of the straps are fastened closer together, wrinkling the body of the bag closing the opening, to then make a knot or bow between the extracted sections of both straps.
  • each tube is formed by folding each side wall towards the inside of the opening , the length of the inner fold preferably extending from the opening to a seam line by means of which the inner fold is fixed to the side wall, forming the cuff or tube inside which the strap is housed.
  • Said seam line preferably coincides with the upper side of the die-cut hole, running along the side wall from one lateral side to the other, but it is interrupted when it reaches said upper side. If the seam line is slightly below the upper side, which is not preferable, it will be interrupted when it reaches the die-cut hole. Also, in another alternative, the seam line can be arranged below the lower side of the die-cut hole.
  • the inclusion of the strap serves as a reinforcement of the bag in its grip area, since, as the strap is arranged above the die-cut holes on each side wall, that is, between said holes and the opening or upper edges of the side walls, the strap contributes to the handle function of the die-cut holes, which in turn are the opening for access to the self-closing strap.
  • the bag can have different configurations, such as, for example, a fold in the lower bottom of the bag that will give it a greater load volume or greater capacity.
  • the bag can further incorporate an additional wall between the two side walls.
  • the materials for manufacturing the strap or straps is preferably polyethylene, but other materials that allow the same function cannot be ruled out.
  • the material of the bag is preferably recycled plastic, without ruling out other materials suitable for bags, such as other plastics or cardboard.
  • the bag (1) of the invention comprises two layers (1a) of sheet material joined together on all sides except the upper side which defines the access opening (1b) to its interior to fill and empty the bag, there being close to said opening (1b) a die-cut hole (2) in each of the two layers (1a) that serves as a handle for transport.
  • the two layers (1a) of the bag are rectangular in configuration ( Figures 1 and 2 ). And it is distinguished by further comprising a self-closing strap (3) inserted into the internal face of the opening (1b) in such a way that it is accessible from the die-cut holes (2) that serve as handles to pull it and be able to tie the extracted sections thereof together to close the opening (1 b), as shown in figure 5 .
  • the self-closing strap (3) is incorporated in a cuff (1c) of the sheet material provided around the perimeter on the inside face of the opening (1b), having a height (h) that covers the position of both die-cut holes (2), that is, the seam line (4) with which it is fixed to the layers (1a) of material is located below said die-cut holes (2), as observed in Figures 2 and 3 , serving as reinforcement of the same when used as handles, the strap (3) being arranged above the position of said die-cut holes (2), that is, between the latter and the upper edge of the opening (1 b), so that the die-cut perimeter itself of the die-cut holes (2) that serve as handles constitutes the opening for access to the self-closing strap (3) ( Figure 4 ).
  • the bag (1) has a cuff (1c) on the inner face of the opening (1 b) that provides two layers of sheet material in the area of the die-cut holes (2) that serve as handles, which confer greater resistance to same.
  • the two layers (1a) of the bag also have a lower fold (1d) at the bottom of the bag (1) that gives it a greater volumetric capacity.
  • the bag (1) can be made of recycled plastic material and the self-closing strap (3), for example, can be made of polyethylene, to impart resistance to same.
  • the following steps preferably take place, but not necessarily in the order indicated below:
