Definitions

  • the subject of the present invention is a dinner packaging for food products, suitable for packing ready-to-go meals, in particular hot ones.
  • menuboxes There are known methods of forming menuboxes from various materials and many packaging constructions. There are several variants of packaging construction and material versions, one of them is the formation of menubox containers from a strip of expanded EPS polystyrene foil. Packagings are also made in thermoforming technology.
  • Packagings suitable for packing ready-to-go dishes are adapted to the type of the dish. For dishes served cold, the packagings do not have to have thermal insulation properties and, on the other hand, it is expected that the packagings will be transparent. Polyethylene terephthalate is most often used for this purpose. These packagings also do not usually contain dishes with a large mass, so their high stiffness is not required.
  • Known packagings may be single-chambered and/or divided into several compartments for the components of a complete dish.
  • the packagings have a main chamber and a lid, connected with each other by a thinner, flexible strip forming an arch, and all parts of the packaging form a uniform structure. They are closed with two protrusions in the lid, mounted in two slots of the main chamber. This connection does not provide the leak-tightness of the packaging.
  • the aim of the invention is to obtain a leak-tight food packaging intended for the transport of ready-to-go meals, in particular hot ones, prepared in restaurants.
  • the packaging consists of at least one-compartment main chamber and a lid.
  • the lid is connected with the main chamber by a thin, flexible strip, and all parts of the packaging form a uniform structure.
  • At the edge of the lid there are at least two horizontal protrusions of the lid having embossings.
  • the main chamber has at least two horizontal protrusions of the chamber, each of which has a recess with a width smaller than the width of the horizontal protrusions of the lid.
  • there are horizontal slots extending under the unembossed part of the protrusion of the chamber.
  • the lid has a vertical, circumferential projection with a flange flanged outward located around its edge.
  • the main chamber has a vertical, circumferential projection with a flange flanged outward, located around its edge except for the area of the strip. Moreover below the vertical projection of the main chamber there is a first horizontal, circumferential offset and below it there is a second horizontal, circumferential offset.
  • the vertical projection of the lid is supported on the second offset of the chamber in the closed position of the packaging.
  • the terms vertical and horizontal relate to their position in space, when the packaging is closed and stands on a horizontal surface. Two corners of the main chamber located on the edge with the flexible strip have additional horizontal projections located above the first horizontal, circumferential offset.
  • the packaging is made of non-oriented, multi-layer expanded polypropylene film.
  • the main chamber and the lid have two horizontal protrusions.
  • the main chamber is divided into two and/or three compartments.
  • the thin, flexible strip has three longitudinal and parallel bends, between which it has the shape of arches bent to the outside of the packaging.
  • the bottom of the main chamber and the top of the lid have embossings on their surface.
  • the packaging according to the invention thanks to the shape of the protrusions and projections of the lid and the main chamber, is a click closure, protecting against uncontrolled opening.
  • the horizontal offsets of the main chamber and the vertical protrusions of the lid seal the packaging.
  • Under the additional protrusions in the two corners of the main chamber goes a flanged part of the lid's flange, creating another click closure protecting against uncontrolled opening of the packaging and its sealing.
  • the packagings of menubox type made of expanded polypropylene XPP are ideal for packaging meals prepared on an ongoing basis, as these packagings are characterized by excellent thermal insulation, thanks to which one can easily deliver the meal to the customer without great loss of heat. Additionally, the content of the packaging do not spill out. Due to the wide range of operating temperatures from 2°C to 120°C of the material used, these packagings are also suitable for storing meals in the refrigerator and for heating products in packaging using a microwave oven.
  • the method of production of the packagings consists in going through all subsequent stages in the thermoforming process.
  • the material in the form of a web of film is unwound from the rolls of the film by means of driven rollers in the unwinding station.
  • the foil then goes to the pre-heating cabinet, where the hot air circulation preheats the foil.
  • the conditions in the cabinet are defined by the requirements of different thicknesses of XPP material in the range of 80°C to 150°C.
  • the pre-heated foil is directed to the forming machine, where the foil is guided by chains responsible for foil movement, in the first part the material is heated to the temperature of 150-250°C.
  • an important element before the forming station is stretching the film guiding chains so that the film sheet transported to the forming station is taut and wrinkle-free.
  • the next stage is the forming station, where the foil sheet is pre-stretched mechanically using forming punches and the main forming using compressed air and vacuum.
  • the time of 1 molding cycle in a single or multi-cavity mold is from 2-7 s.
  • the material that has spent a certain period of time in the forming cavity reproduces the final shape of the packaging.
  • the formed foil sheet is released and then the sheet with formed moldings is transported to the cutting station, where the moldings are cut out with the help of guides in the upper cutting plate and dies made of steel tape and adapted to the shape of the packaging.
  • the cutting station operates using toggle levers.
  • the blades are equipped with point transport bridges enabling further transport of packagings to the stacking station.
  • the packagings are separated from the blanking scrap.
  • a robot which is equipped with arms ended with vacuum suction cups, molded parts are collected.
  • At the bottom of the robot there are baskets used to push packagings out of the foil sheet.
  • the robot moves in three axes in vertical and horizontal guides and performs axial rotation.
  • the robot's operation is set by programming the parameters depending on the multiplicity of the mould, dimensions of the packaging and stacking height.
  • Packagings collected in stacks of a few and/or several pieces are transferred by means of a robot to the conveyor belt to be collected and packed into cardboard boxes.
  • the material remaining after cutting out the packagings in the form of a blanking scrap is wound on a winder and/or is led directly to the mill for reuse in other processes.
  • Film for production of packagings is made of non-oriented, multi-layer expanded polypropylene film. It is obtained by an extrusion method using polypropylene in the form of granules.
  • the XPP foil extrusion technology can be divided into the following stages:
  • XPP film is characterized by excellent technical parameters, while maintaining very good optics of the material.
  • the raw material from which the menubox packaging film is made is resistant to weak acids, alkaline solutions, oils and fats, therefore the film can be used as a monopackaging, which is a component of trays for packaging food products.
  • the structure of the XPP film by its expanding generates the appropriate surface tension of the film, and therefore it is possible to print the packaging with offset inks, as well as flexographic or screen printing.
  • Packagings made of XPP foil are formed in a production line intended for thermoforming packagings from unrolled foil web.
  • the machine is made of the following elements, one after the other:
  • the packagings consists of a main chamber 1 divided into two compartments 1a and 1b and a lid 2.
  • the lid 2 is connected with the main chamber 1 by a thin, flexible strip 3, and all parts of the packaging form a uniform structure.
  • On the edge of the lid 2 there are two horizontal protrusions 4 of the lid 2 having embossings 5.
  • the main chamber 1 has at two horizontal protrusions 6 of the chamber 1, each of which has a recess 7 with a width smaller than the width of the horizontal protrusions 4 of the lid 2.
  • there are horizontal slots 8 extending under the unembossed part of the protrusion 6 of the chamber 1.
  • the lid 2 has a vertical, circumferential projection 9 with a flange 10 flanged outward located around its edge.
  • the main chamber 1 has a circumferential, vertical projection 11 with a flange 11 a flanged outward located around its edge except for the area of the strip 3. Additionally below the vertical projection 11 of the chamber 1, inside, there is a first horizontal, circumferential offset 12 and below it there is a second horizontal, circumferential offset 13.
  • the vertical projection 9 of the lid 2 is supported on the second offset 13 of the chamber 1 in the closed position of the packaging.
  • the terms vertical and horizontal relate to their position in space, when the packaging is closed and stands on a horizontal surface.
  • the thin, flexible strip 3 has three longitudinal and parallel bends 3a, between which it has the shape of arches bent to the outside of the packaging.
  • the packaging is made of non-oriented, multi-layer expanded polypropylene film.
  • the packaging was made of 1.4 mm thick XPP foil. Additionally the packaging is characterized by excellent thermal resistance, what was confirmed by tests. This resistance is possible due to the use of a tight structure and use of expanded polypropylene film, which increases thermal insulation due to the content of air bubbles. A test consisting in measuring the temperature of liquid heated to 100°C after 10 minutes showed higher temperature by more than 10°C for the said containers in comparison to the currently used packagings made from EPS.
  • a packaging was made as in the example 1, where the chamber 1 was divided into three compartments 1a, 1b and 1c.
  • a packaging was made as in the example 1, where the chamber had one compartment.
  • the packaging was made of a thinner foil with a thickness of 1.05 mm.
  • embossings 15 and 16 were made in the bottom of the main chamber 1 and in the lid 2.
