Definitions

  • the present invention relates to a method for making fibre box-like containers and related covers, and the containers made thereby.
  • box-like bodies provided with a respective cover, which have a substantially parallelepipedal shape and are made of fibre materials, that is including a plurality of superimposed kraft paper layers, glued to one another so as to provide a desired consistency.
  • a cover member In order to apply to these box-like containers a cover member, two procedures are conventionally adopted, the first of which consists of making a cover having a peripheral profile larger than the peripheral edge of the box-like body so as to provide an overlaying type of coupling, with the cover projecting from the side surface of the container body.
  • a core that is a band, extending starting from the bottom of the container and projecting, at the top of said body, so as to define the coupling region for a cover, which has the same peripheral shape as the box-like body.
  • the aim of the present invention is to ovecome the above mentioned drawbacks by providing a method for making fibre box-like containers and related covers, which provides a container having a smooth side surface, that is with a flush arranged container cover, without using any additional elements, such as an inner core member.
  • a main object of the present invention is to provide such a method which allows a container to be made which has an increased mechanical strength.
  • Yet another object of the present invention is to provide such a container making method which is very reliable and affords the possibility of making containers starting from easily available materials and elements.
  • Yet another object of the present invention is to provide such a method which is adapted to make containers and related covers which are very competitive from a mere economic standpoint.
  • a method for making fibre box-like containers and related covers comprising the steps of making a tubular container body including superimposed paper material sheets, stretching said tubular body by rollers arranged at corner portions of said tubular body, causing said tubular body to assume a substantially parallelepipedal shape, characterized in that said method further comprises the following steps of: deforming, by a mold, an axial end portion of the tubular body so as to provide an edge substantially parallel band recessed from a side surface of said tubular body, inwardly bending corner regions of said tubular body in order to remove the material excess and making a container cover having the same peripheral extension as said box-like container body.
  • the method for making fibre box-like containers, and related covers comprises the step of preliminarily making a tubular body 1, of a substantially circular cross-section, which is made, in a known way, by superimposing and glueing a plurality of kraft paper sheets, so as to provide an article of manufacture having a desired consistency.
  • the container tubular body 1 After having made the container tubular body 1, of circular cross-section, it is arranged on rollers 2 which are subjected to a spreading movement so as to stretch the tubular body, as is shown in figures 2 and 4, in order to cause said tubular body to assume a substantially parallelepipedal shape, with rounded corners, at the region in which said rollers 2 operate.
  • tubular body having a polygonal cross-section and a desired size
  • lengths of tubular body corresponding to the length of the box-like body to be made are cut therefrom.
  • an axial end of the tubular body length is introduced into a mold 10 having an inner die 11 including, on its side surface, recessed portions 12 arranged under a projecting portion 13 turned toward said tubular body.
  • a pressing element 20 driven by hydraulic or the like driving means, and including a shaping projection 21 arranged at the mentioned recess, and with a restraining undercut 22, arranged at said projection 13.
  • the axial end portion of the tubular body will be deformed so as to provide a recessed edge with parallel faces, with respect to the side surface of the container.
  • shaped pressing elements 25 adapted to form a recessed zone 26 at the corner region of the edge band, so as to allow the material excess provided by the edge band recess, to be inward displaced with respect to the side surface.
  • a region will be formed, i.e. the edge band, which is so shaped that it can be easily introduced inside a cover 50, made by a conventional method which, in its assembled condition, will be flush with respect to the container body.
  • the edge band will practically also provide a stiffening rib along the overall extension of the tubular body.
  • the coupling region between the edge band and the side surface, indicated at 27 will operate as an abutment element for the free edge of the container cover.
