Definitions

  • a machine for emplacing and forming lids on filled cartons is comprised of a lid supply means and a carton receiving station. Means are provided for feeding the lids to a position above the carton receiving station where the open top of the carton is mated with the lid which is formed by pressure rollers to conform to the carton walls.
  • the lids have flaps and corner tabs which are folded downward and inward and adhered to the flaps which engage the carton walls, all of the folding is done in sequence but simultaneous steps. Novel means are provided for adapting the machine to various lid sizes thus reducing the inventory of blank lids that must be stocked for various carton sizes.
  • cut size packages of paper are difficult to handle for transport and sale because the packages are bulky, heavy and, in a sense fragile.
  • the industry has adopted the practice of packing the cut size packages in a carton usually containing 5,000 sheets divided into equal packages or reams of 500 sheets each.
  • the outer carton is usually fabricated from corrugated paperboard having sufficient strength to encompass and confine the plurality of packages while protecting same against impact or shock that would render the wrapped sheets unusable because of wrinkles, tears, curled edges, and bent corners and the like. Because of the necessity for strength and impact resistance, the board from which the cartons are fabricated must be of substantial thickness and weight, thus making the carton and contents quite heavy to further increase storage bulk and shipping costs en route from manufacturer to consumer.
  • the closure blank is fed into place over the filled container.
  • the filled container is then elevated into what the art terms a well which folds the closure around the sides of the container and, in some cases, adheres the folded sides of the closure to the container.
  • a well usually consists of a stationary member or members defining a periphery of an open hole into which the container is lifted.
  • the stationary members contact the edges of the blank and, as the container moves upward, the relative movement past the stationary members causes folding of the marginal edges of the blank down along the container walls, which walls are generally vertical and parallel to the longitudinal axis of movement of the container. Since an extremely tight fit of the closure to the container is necessary, the edges or stationary members defining the mouth of the well are positioned and spaced so as to very closely, within inch or less, approximate the dimensions of the outer dimensions of the side walls of the container. In all cases, the folding pressure required to bend the marginal surfaces of the closure,
  • the present invention has for a general objective the provision of a relatively inexpensive efficient and extremely versatile carton lidding machine.
  • a particular object of the invention is to provide a carton lidding machine capable of producing tightly lidded cartons which are integrated with the contents to provide improved impact resistance to the package and contents.
  • Another object of the invention is to provide a lidding machine which can be installed easily in any carton packing line.
  • a further object of the invention is to provide a lidding machine which is readily adjustable to accommodate different sizes of cartons.
