Definitions

  • the present invention relates to a package for holding a food product, in particular a pourable food product such as yoghurt, milk or the like.
  • the present invention also relates to a mould for a packaging machine.
  • pourable food products such as fruit juice, milk, UHT (ultra-high-temperature treated) milk, wine, tomato sauce, yoghurt, cottage cheese, soup, salt, sugar etc.
  • pourable food products such as fruit juice, milk, UHT (ultra-high-temperature treated) milk, wine, tomato sauce, yoghurt, cottage cheese, soup, salt, sugar etc.
  • Tetra Brik Aseptic sold by Tetra Brik Aseptic (registered trademark).
  • Tetra Brik Aseptic sold by Tetra Brik Aseptic (registered trademark).
  • the packaging material has a multilayer structure comprising a carton and/or paper base layer, covered on both sides with layers of heat-seal plastic material, e.g. polyethylene.
  • the packaging material also comprises a layer of oxygen-barrier material, e.g. an aluminum foil, which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material forming the inner face of the package eventually contacting the food product.
  • a package for holding a food product comprises a main body formed from a multilayer packaging material that comprises a layer of fibrous material and a lid structure formed from a plastic material and attached to the main body.
  • the main body has: a bottom section, a wall section extending from the bottom section for forming an inner space for the food product, and an opening arranged at an end of the wall section that is opposite to the bottom section.
  • the lid structure is configured to seal the opening and the inner space (14) and comprises: a lid frame attached to the main body at the opening, a lid detachably joined with the lid frame and sealing the opening in cooperation with the lid frame, and a pull element connected to a peripheral portion of the lid and configured to, when pulled, exert an opening force on the lid so as to at least partially detach the lid from the lid frame and thereby at least partially freeing the opening.
  • the package is advantageous in that by arranging the pull element at the peripheral portion of the lid, it is possible to efficiently direct the opening force, at the very beginning of the opening, onto a locally restricted portion of the lid thereby allowing to improve the separation of the lid from the lid frame. This provides for an opening that allows easy access to the food product held by the package.
  • the pull element may extend from a lid top surface of the lid by an angle that is in the range of 50° to 100° or in the range of 70° to 90° or (substantially) 85°.
  • the angle may be the angle between a plane of the lid top surface of the lid and a direction by which the pull element extends from the lid, at the location where the pull element is connected to the lid and measured on a side of the pull element facing a center of the lid. In this way, it is possible to further guarantee the concentration of the opening forces.
  • the pull element may be connected to the lid at one coupling point only or at two coupling points only. This allows to direct and concentrate the force on one single portion of the lid further improving the efficiency of the detaching of the lid.
  • the pull element may comprise a ring-shaped gripping structure
  • the lid may comprise a depression that is located beneath the ring-shaped gripping structure. In this manner, it is possible to allow for an improved housing of the ring-shaped gripping structure.
  • the ring-shaped gripping structure may be closed or may be open with its ends connected to the lid or to two elements (legs) that extend from the lid.
  • the lid may comprise a protrusion that extends over the lid frame, and the pull element may be connected to the protrusion. This allows to even further improve the separation properties of the lid from the lid frame.
  • the lid may cover at least 90% of the opening of the main body. In this way, it is possible to liberate a significant portion of the opening facilitating the access to the food product, in particular for consumption-on-the-go solutions.
  • the lid frame may comprise a frame top surface extending along an entire periphery of the opening of the main body.
  • the lid may comprise a cover portion and a lid wall section.
  • the lid wall section may extend around a peripheral section of the cover portion and may be joined to the lid frame and may lift peripheral section of the cover portion above the frame top surface. The presence of the lid wall section allows the forces to follow the orientation of the lid wall section itself, thereby allow to concentrate the forces and to facilitate the separation of the lid from the lid frame.
  • the lid may comprise a tip-shaped protrusion extending into the lid frame, at a location underneath the pull element.
  • the tip-shaped protrusion allows to concentrate the forces onto the interface formed between the tip-shaped protrusion and the lid frame leading to even further improved separation properties of the lid from the lid frame.
  • the lid structure may comprise a tear section that is located where the lid is joined with the lid frame.
  • the tear section guarantees on the one side the joining between the lid frame and the lid and provides on the other side for the possibility to detach the lid from the lid frame.
  • At least 70% of the length of the tear section may follow a contour that has the same shape as the shape of the contour of the opening of the main body. In this way one ensures to easily access the food product.
  • the lid may be at least partially detached, the entire periphery of the lid has exact correspondence to an inner part of the lid frame from where the lid was detached. In this manner, the lid retains its original structure and is simply detached from the lid frame without any incision or the like within the lid.
  • the tear section may comprise a tip-shaped section that extends into the lid frame, at a location underneath the pull element. This allows to concentrate at the very beginning of the separation of the lid from the lid frame to a localized portion.
  • the tear section may be interrupted at a side of the opening of the main body that is opposite the side of the main body where the pull element is located. This allows to guarantee that the lid remains attached to the lid frame, thereby that the lid will be correctly disposed with the rest of the package.
  • the tear section may comprise an angled-side portion that, at the side of the main body where the pull element is located and at a respective side of the pull element, extends with an angle relative an outer periphery of the lid frame, such that the distance between the tear section and the outer periphery of the lid frame increases along the angled side portion, in a direction away from the pull element.
  • a mould for a packaging machine comprising a cavity having a shape that corresponds to the shape of the above-described lid structure of the package.
  • the mould allows to shape the lid structure and attach it onto the main body of the package.
  • an exemplary package 1 for holding a food product in particular a pourable food product, such as milk, yoghurt, cottage cheese, tomato sauce, soup, salt, sugar or similar, is illustrated.
  • a food product such as milk, yoghurt, cottage cheese, tomato sauce, soup, salt, sugar or similar.
  • package 1 comprises a main body 2 formed from a multilayer packaging material 3 and a lid structure 4 attached to, in particular molded onto, main body 2.
  • the multilayer packaging material 3 may comprise: a layer of fibrous material 5, such as e.g. paper or cardboard, and at least two layers of heat-seal plastic material 6, e.g. polyethylene, interposing the layer of fibrous material 5 in between one another.
  • a layer of fibrous material 5 such as e.g. paper or cardboard
  • heat-seal plastic material 6 e.g. polyethylene
  • the multilayer packaging material 3 may also comprise a layer of gas- and light-barrier material 7, e.g. aluminum foil or ethylene vinyl alcohol (EVOH) film, in particular being arranged between one of the layers of heat-seal plastic material 6 and layer of fibrous material 5.
  • the multilayer packaging material 3 may also comprise a further layer of heat-seal plastic material 8 being interposed between layer of gas- and light-barrier material 7 and layer of fibrous material 5.
  • the main body 2 comprises: a bottom section 12, a wall section 13 extending from bottom section 12, in particular along a central (longitudinal) axis A, for forming an inner space 14 for the food product, and an opening 15 arranged at an end 16 of the wall section 13, which end 16 is opposite to bottom section 12.
  • the lid structure 4 is attached onto the main body 2 so as to seal the opening 15 and the inner space 14.
  • the lid structure 4 may be manipulated such that a consumer can access the inner space 14, e.g. so as to outpour the food product from the inner space 14 and/or to directly consume the food product out of the main body 2.
  • the bottom section 12 may define a support surface of package 1, in particular of the main body 2, which is configured to be put in contact with a support surface, such as e.g. a shelf, in particular when, in use, being e.g. exposed within a sales point or when being stored.
  • a support surface such as e.g. a shelf
  • the bottom section 12 is to be arranged at a lower position than the other positions, when being placed on the support surface.
  • bottom section 12 defines the lowest portion of package 1.
  • the bottom section 12 defines the lowest position of main body 2.
  • any references referring to top, bottom, upper, lower, above, beneath and similar refers to package 1 being placed e.g. on a support surface or when being held by a consumer when this latter intends to manipulate lid structure 4, having the bottom section 12 at the lowermost position while the lid structure 4 and thus the opening 15 are located vertically above the bottom section 12.
  • a "correct" orientation of package 1 is such that bottom section 12, when being viewed by the consumer, is arranged at a lower position than lid structure 4 as otherwise the manipulation of lid structure 4 would lead to a non-desired spilling of the food product.
  • the end 16 may be arranged at an upper position than the bottom section 12. In other words, the end 16 may define a top end of the main body 2.
  • the package 1 may also comprise a cover 17 (only shown in Figure 1 ), in particular a plastic cover 17, removably coupled to main body 2 and covering the lid structure 4.
