Definitions

  • the present invention relates to a method according to the preamble of patent claim 1.
  • the bag surrounding the ground coffee (insert bag or inner bag) must be adapted to the coffee volume that varies during the packaging process. This is usually done by adjusting the package height accordingly.
  • the inner cover is made from a very tough composite film that often has to be opened with scissors and a knife.
  • Opening aids with a tear cut or cut at the top closure can provide relief. However, they have the disadvantage that the crack for opening the pack is not controlled.
  • the machine device for attaching the tear strip can adversely affect the efficiency and the output of the packaging system. Tear incision and thread make it easier to open the pack.
  • the outer carton When packing according to item 4 with inner bag and outer carton, the outer carton has a plastic frame at the top, within which the inner bag is visible. To open the hard vacuum pack, this inner bag zone must be cut open with a knife. After partial removal of the ground coffee, a plastic cover is placed over the plastic frame to reclose the vacuum pack. Filling this vacuum pack on the The packaging line is on the bottom side. For this purpose, the packaging for filling and closing goes through the packaging system with the plastic frame and lid down.
  • the package according to item 4 is the only one that offers a reclosable option after a partial removal of the product.
  • the adaptation to the volume fluctuations of the ground coffee takes place: - in the vacuum packs according to item 1 or 2 by changing the height of the single or double bag; - for the packs according to item 3 or 4 through the variable cavity between the inner bag fold and the glued outer cardboard cover flaps.
  • Plastic frame with slip lid
  • the invention is therefore based on the object of creating a method with which the production of a vacuum pack which, as shown in FIGS. 1 to 4, fulfills the conditions mentioned above.
  • This object is achieved according to the invention by a method having the features specified in the characterizing part of claim 1.
  • the insert vacuum pack can be produced with printed, grooved and finseal (inside against inside) longitudinally sealed pack blanks made of a rigid composite packaging material.
  • the composite packaging material can also be removed from the roll in printed and grooved condition.
  • the package height can be adjusted with a tendency control to the volume of ground coffee that varies during the packaging process.
  • the printed, grooved and longitudinally sealed packaging blank or the printed and grooved packaging section removed from the roll can statically regulated and cut to the length corresponding to the package height. The cut is made on the opposite side of the floor scoring.
  • the packing sleeve is shaped - in the case of the longitudinally sealed, flatly folded package blank by opening the same and - With the packaging material removed from the roll, by shaping and longitudinally sealing the packing sleeve on a multi-part, indexing wheel.
  • the intermittently supplied plastic cover with the tear-open tab is sealed on a mandrel molding wheel or molded part and then the pack is inserted with the plastic cover downward into a switchable package cup transport. After being pre-folded, the packs can be filled from the bottom, shaken, measured with a button for the respective fill level, sealed with an expansion fold and partially sealed.
  • the packages slide in package cup transport on a floor rail that is adjusted according to the variable filling volume or the package height required for this.
  • the floor rail is adjusted using the fill level button mentioned about a statistical regulation.
  • This statistical regulation also called trend regulation, also provides the adjustment for the cutting of the packaging material blank to the length corresponding to the package height mentioned at the beginning.

  • CO2 When roasting coffee beans, CO2 is produced, which is contained in the cells of the coffee beans with excess pressure. When grinding the bean coffee, the CO2 can from the grinding open cells of the coffee grains escape. The CO2 with excess pressure remains in the remaining closed cells. This CO2 can slowly diffuse through the thin cell walls, causing the excess gas pressure in the cells to break down.
  • the duration for the CO2 to escape from the cells of the coffee grains depends on the degree of roasting, the degree of grinding, the origin and harvest of the coffee. In order to allow this CO2 to escape from the ground coffee, it is temporarily stored under vacuum for a certain time before packaging. If the coffee is vacuum packed after grinding without intermediate storage, the CO2 escaping with excess pressure can reduce the negative pressure in the vacuum packs and even cause the pack to expand.
  • This inflation of the packs can, as shown in FIG. 1, be avoided by using a one-way pressure relief valve 124.
