Definitions

  • the present invention relates to a novel procedure for packaging liquid products in envelope-type receptacles or wrappers, commonly known as "packeting", which procedure is particularly suitable for packaging oily or viscous products such as, for example, honey.
  • the invention also relates to a packaging machine which permits implementation of the above-mentioned procedure.
  • the invention additionally relates to the package obtained with this packaging procedure and this packaging machine.
  • Injection/metering machines which, either using a continuous tubular body with a plastic nature or, alternatively, two sheets which the actual machine welds longitudinally in order to convert them into a tubular body, establish transverse heat-sealing lines in said tubular body and, immediately after each transverse heat-sealing line, supply the tubular body with a metered amount of product, thereby arriving at the various metered amounts being received in independent vessels established in longitudinal alignment over the continuous tubular body which is then divided up in order to obtain the unitary packages of product.
  • each operating unit or each unitary machine can make and fill the packages only one by one, that is to say that this is a repetitive process, with intermittent stops, in which the following sequence of operations takes place: metering of the product and its supply to a unitary package, closure of the package; metering and supply of the product to a new unitary package, closure of the package, and so on.
  • the packages can be closed only either at atmospheric pressure or, alternatively, at a specific pressure with which the operating mechanisms of the machine are surrounded and which requires pressurizing means separate from the machine, with the consequent rise in costs that this involves.
  • the procedure proposed by the invention is based on a substantially different functional philosophy, according to which packaging takes place in two phases which, in addition, can be combined into a continuous process or, alternatively, be completely separate from each other.
  • the first phase coincides with the conventional method of packaging, but with the particular feature that a greatly oversized package is achieved which holds inside a considerable number of unitary metered amounts of product which are, however, combined as a multiple metered amount.
  • the package with the multiple metered amount obtained in the first phase is subjected, firstly, to a uniform distribution of the product accommodated inside and then to a dividing-up operation, using heat-sealing and cutting, which results in the definitive unitary packages with their corresponding metered amounts which are also unitary.
  • the bulk product may be prepackaged in the oversized packages containing multiple metered amounts and be kept under these conditions, while it is deemed convenient, up to definitive compartmentalization and dividing-up of these packages.
  • the machine for implementing the procedure in addition to the conventional injection/metering/heat-sealing apparatus for carrying out the first phase of the procedure, will incorporate a conveyor belt for receiving the oversized packages obtained in the first phase, on which belt a series of smoothing rollers responsible for uniformly distributing the product inside said oversized packages will act.
  • a conveyor belt for receiving the oversized packages obtained in the first phase, on which belt a series of smoothing rollers responsible for uniformly distributing the product inside said oversized packages will act.
  • a press or subdividing station equipped with grids which can be changed (or which can be regulated in terms of height when dealing with envelopes), with which the product is held along lines which form parcels or segments of various configurations.
  • the four operating sectors mentioned above are in the upper block of the press, generally the movable block, in longitudinal alignment.
  • a package press plate is located in the first of them; a plurality of presser-expeller rubbers aligned in one direction, for example longitudinally, in the second; presser-expeller rubbers are also in the third sector but, in this case, in a cross arrangement with respect to those of the previous sector, for example in the transverse direction; finally, in the fourth and last sector there is a die, the cutting lines of which coincide numerically and in terms of position both with the longitudinal and transverse presser-expeller rubbers.
  • the lower block are four sectors opposite those of the upper block.
  • the first sector is smooth and the upper sector consisting of the package press plate acts on it;
  • the second sector is provided with resistance elements which coincide numerically and in terms of position with the presser-expeller rubbers of the second sector of the upper block;
  • the third sector is provided with resistance elements which assume an arrangement coinciding with that of the presser-expeller rubbers of the third sector of the upper block;
  • the fourth sector is provided with a plurality of longitudinal and transverse grooves defining a reticular cut for actuation of the cutting die in the fourth sector of the upper block.
  • each block may be physically independent from one another, associated with a common support inside each block, or may constitute a monobloc assembly without this affecting the functional characteristics of the press, the upper block of which will preferably be actuated by pneumatic pistons.
  • the invention also relates to the package obtained as a result of using the procedure and the machine which have been described above; this "envelope"-type package has its characteristics centred around a special configuration of its walls, according to which they have a cross section derived from a biconvex or elliptical lenticular shape as a result of the pressure exerted on the walls by the product, which leads to elimination of the conventional play between container and contents and ensures easier emptying-out of the contents.
  • filling of the oversized package takes place at such a pressure that, once said package is subdivided, each unitary package is filled to a proportion of approximately 80 - 85 %, which gives rise to a pressure permitting total emptying-out.
  • a pneumatic metering device (1) which is conventional per se, with the following elements: the tank (2) for supplying the product, an injector (3) assisted by a motor (4) and a heat-sealer (5) with the corresponding timer controls (6), all this being mounted on a lower body (7) with its corresponding general controls (8).
  • a series of packages (9), which are considerably oversized, are formed unitarily and sequentially in this metering unit, and these packages, as mentioned above, will each hold multiple metered amounts of the product in question accommodated in the tank (2), each of these oversized packages (9) being completely sealed.
  • these packages (9), conveniently grouped together, are set up at the exit from the injection/metering/heat-sealing apparatus (1) on pallets (10) in the form of a frame, in which they are conveniently fixed with the collaboration of end clamps (11), these pallets (10) being deposited on a conveyor belt (12) assisted by a pair of end pulling rollers (13) and (14), one of them actuated by the corresponding motor (15).
  • Figure 2 shows a pallet in the form of a frame with six oversized packages (9) held by the clamps (11).
  • a press (17) preferably actuated by pneumatic pistons (18), which press is intended to constitute a station for subdividing the packages (9) and which consists of changeable grids (19) and (20) located respectively on its movable and stationary parts, the grid (19) having a series of ribs (21), preferably of rubber, which define a lattice with the shapes corresponding to the unitary packages (22) to be obtained, as may be observed especially in the detail of Figure 3, whilst, in the changeable grid (20) of the stationary part of the press (17), there are, forming a lattice of identical format, electrical resistance elements (23) for heat-sealing and cutting; the pressure of the movable grid (19) over the package (9) having a multiple metered amount, along the lines of the drawing formed by the ribs (21) and the electrical resistance elements (23), provided in the stationary grid (20), gives rise to the dividing-up of the package (9) into the various unitary packages (22).
  • the smoothing rollers (6) may be eliminated, carrying out an equivalent function in the actual press (17') which constitutes the exit element of the packaging machine and where the second phase of the procedure is carried out.
  • the first operating sector (33) consists of a package press plate which flattens and smoothes the packages originating from the injection/metering/heat-sealing apparatus (1); a smooth base (34) in the first sector of the lower block (32) collaborates with this plate so that the package is pressed between these elements to achieve a uniform distribution of the product contained therein.
  • the fourth sector (41) of the upper block (31) is provided with a cutting die (42), of reticular structure, corresponding with the longitudinal rubbers (36) and the transverse rubbers (36'), a reticular groove (43) in the fourth sector (44) of the lower block (32) collaborating with said die (42) so that, through this fourth sector (41-44) of the press definitive separation is achieved for the bag-type unitary packages (45), which are, in turn, shown in Figure 9.
  • FIG. 9 shows, diagrammatically and sequentially, the operating process of the press, on the basis of the four operating sectors (33-34), (35-37), (39-40) and (41-44) in the upper (31) and lower (32) blocks of the press.
  • the upper block (31) descends, through actuation of the pneumatic pistons (47)
  • the oversized package (48) arriving at the press and which has a broad rectangular surface undergoes, in the first sector, a uniform distribution of product contained inside it, in which phase the package has been given the reference number (49); next, said package passes to the second sector (33-38), where it is given the reference number (50) and a series of longitudinal heat-sealing lines (51) is made on it; next, and in the third operating sector, the package (52) receives the transverse heat-sealing lines (53), that is to say lines perpendicular to the previous ones, thereby defining within them the unitary packages (45), that is to say the packages carrying unitary metered amounts; finally, in the fourth operating
  • These packages (45) consist of a laminar structure of an impermeable nature, specifically based on two sheets of plastic which are heat sealed around their perimeter (56) to retain the viscous product (57) held inside and, through the effect of the actual pressure supplied to the original package (48) of large dimensions, they adopt, on application of the longitudinal (51) and transverse (53) heat-sealing lines, a markedly curved/convex configuration so that their cross section is derived from an ellipse, oval or biconvex lenticular shape.
  • the package offers a large volume for specific perimeter dimensions, additionally facilitating emptying-out of the package with just one hand, after making a cut (58) in one of the corners of the package, as shown in Figure 11.
  • the pressure exerted with just one hand is added to the internal pressure of the package which causes the natural and virtually total exit of the viscous product contained therein.
