Definitions
- the present invention concerns the field of cardboard packaging and in particular it concerns a container provided with at least one conical, truncated cone-shaped or truncated pyramid-shaped portion provided with an improved opening system.
- the invention further concerns a process and a machine for making the above opening system.
- Cardboard containers and in particular cardboard containers having a truncated conical shape such as, for example, those used for packaging panettone, pandoro and similar products, currently have a knock-out opening system disposed on the bottom.
- said systems have lines of weakness or pre-cutting which define a removable portion of said container, removal of which forms a sufficiently large opening in the package to allow access to the contents of the container for removal thereof.
- the lines of weakness or pre-breaking define a strip of cardboard, removal of which allows the container to be divided into two parts, usually a top and a bottom part.
- the removable portion or dividing strip therefore has a protruding tab or strip, connected to the lines of weakness, on which the consumer acts by pulling to cause removal of the above portion.
- the object of the present invention is to solve the problems of the prior art by proposing a container provided with an improved opening system that allows opening thereof in any condition.
- Another object of the present invention is to provide an improved opening system that is simple and intuitive for any user to use and allows the product to be presented upright, ready for use on the supporting base.
- Yet another object of the present invention is to provide such an opening system that is cheap to make and reliable.
- Another object of the present invention is to provide a machine to produce such an opening system that is cheap and simple to make.
- the container according to the invention has the characteristics claimed in appended independent claim 1.
- the machine for making the opening system according to the invention has the characteristics of appended independent claim 8.
- the container according to the invention has a truncated cone or truncated pyramid shape comprising a side wall closed at the bottom by a base and at the top by a lid and is provided on the inside with a single adhesive tape of plastic material applied to a perimeter thereof and constrained to a pull tab cut in the cardboard of said side wall, so that pulling on said tab causes guided tearing of a strip of said side wall with a width substantially corresponding to the width of said inner tape.
- the machine for applying the tape of plastic material to a blank shaped as a section of circular crown forming said side wall of the container substantially comprises an application head for said tape that can be moved along a circular path to apply said tape, by means of a presser member, to said blank along a portion of circumference parallel to the portions of circumference of the section of circular crown of which said blank is made up.
- FIGS 1, 1a and 2 a cardboard container 1 particularly for leavened products such as panettone, pandoro and the like according to the present invention is illustrated.
- cardboard used in the present description, must be understood in the broad sense and also comprises multiply materials having at least one cardboard layer.
- the container 1 has a truncated cone-shaped or truncated pyramid-shaped side wall 2, closed at the bottom by a base 3 and at the top by a lid 4.
- the base 3 can have a tray shape which protrudes at the bottom from the side wall 2 of the container ( Figure 1), as illustrated in the figures, or can have a flat shape and be recessed into the side wall 2 ( Figure 1a). It is fixed by gluing or bonding (welding) to the side wall 2 by means of an edge folded to the inside thereof, in a per se known manner.
- the lid 4 can be made from the same blank as the side wall 2, or from a separate blank, as in the embodiment shown in the appended figures.
- the lid 4 is fixed by gluing or bonding, to the truncated cone-shaped side wall 2.
- the side wall 2 is made from a blank 23, which, developed in plan view, as shown in Figures 3 and 4, is shaped as a sector of circular crown and is provided, at one end thereof, with a flap 40 defined by a scored line 5.
- the flap 40 during assembly of the container 1, is superimposed on the other end of the blank 23 and glued or bonded thereon to bring the blank 23 to its truncated cone-shaped condition.
- the truncated cone-shaped side wall 2 has an improved opening system according to the present invention.
- Said opening system consists of a thin tape 6 of plastic material, sufficiently strong, adhesive on only on side, which is applied firmly to the truncated cone-shaped wall 2 of the container 1 so as to encompass the entire circumference thereof.
- the tape 6 is made to adhere by gluing to the truncated cone-shaped portion 2.
- Suitable tapes for the present invention are polyester or polypropylene tapes which have a width in the range of 1 to 4 mm.
- the tape 6 preferably has a width of about 3 mm.
- the crosswise measurement of the tape 6, that is to say its width, is chosen within the above range to give a good mechanical strength thereto and allow application thereof to the cardboard of the container following a curved path substantially without folds or creases.
- the tape 6 is disposed at a fixed distance from the lower edge of the truncated cone-shaped side wall so as to run along the entire length thereof.
- the tape 6 is connected to a tab 7 made on the blank 23 of the truncated cone-shaped wall 2 of the container.
- the tab 7 which protrudes slightly from the blank 23 is defined by two curved side incisions or cuts 70 made on the blank 23, and represents a gripping means for the user.
- a cardboard strip 8 whereon the tape 6 of plastic material is applied is removed by tearing from the truncated cone-shaped wall 2.
- the removed strip 8 has substantially the same width as the tape 6 of plastic material.
- the tear can be stopped before the occurrence of complete detachment of said two parts of the container, which remain attached for a portion, but in any case determining such an opening as to allow the product to be removed from beneath.
- the container can be closed again in the event of partial consumption of the product.
- the blank 23 could advantageously have two parallel lines of weakness coinciding with the area of application of the tape 6.
- it could have an upper and a lower line of weakness which run along the entire circumference of the truncated cone-shaped wall and are placed at a reciprocal distance substantially equal to the width of the tape 6.
- the tape 6 is applied to the truncated cone-shaped wall between the two lines of weakness.
- Application of the single adhesive tape 6 to the truncated cone-shaped wall 2, that is along a curve, which represents the essential characteristic of the opening system of the container according to the invention, is not a simple operation.
- the machine for performing application of the tape 6, shown diagrammatically in Figure 5, comprises an unwinding reel 9 for the adhesive tape 6 and a series of rollers 10 for conveying and aligning the tape, made of Teflon® to reduce friction with the adhesive side of the tape 6. Downstream of the conveying rollers there is a straightening guide 10, able to rotate the orientation of the tape 6 by 90°, to send it to idle roller 50, also of Teflon®, which deflects the path thereof by 90°.
- a second straightening guide 11' Downstream of the roller 50 there is provided a second straightening guide 11', which sends the tape to a series of guide rollers 19, 21, with horizontal axes, two of which 21 are dancing rollers, to keep the tape always at the right tension.
- the tape 6 undergoes a further rotation around its direction of travel by means of a straightening guide 13, to be sent to a second idle roller 14 which returns it, through a third idle roller 51 and a further straightening guide 52, to an application head 12, wherein means are disposed for drawing of the tape 6 and application thereof to the blank 23.
- the application head 12 is carried by a rocking arm 16 hinged around a centre of rotation coinciding with the axis of the roller 14 and moved in rotation by an actuator, such as a cylinder-piston assembly 15.
- the free end of the arm 16, which during the stroke of the arm describes an arc of circumference equal to the curved path of application of the tape 6, has a pressure element responsible, during the stroke of the arm 16, for adhesion of the tape 6 to the blank 23.
- the blank 23, in the open condition, that is to say in the condition shown in Figures 3 and 4, is brought level with the application head 12 of the tape 6 by means of a step by step conveyor chain 20 and is drawn by means of a pair of pusher nibs 18.
- the blank 23, coming from a special store, not shown, is disposed on the conveyor chain 20 transversally to the direction of travel F, as shown in Figure 5.
- the conveyor chain 20 is disposed so that the midline thereof passes through the centre of rotation 14 of the rocking arm 16.
- the cylinder-piston assembly 15 and the conveyor chain 20 are synchronised so that the latter stops for the time necessary for application of the tape 6, when the blank 23 arrives under the application head 12.
