Definitions

  • the present invention relates to the field of packages, for example packages for food products, such as flour or the like. More particularly, the present invention relates to the field of packages comprising a bag of flexible material and an element folded along a folding line and placed outside the bag, for example to report information on the product contained in the packages.
  • packages of flexible material are known on the market, for example packages for food products such as flour, mixes for pizza, mixes for desserts, sugar and so on.
  • packages generally comprise a bag of flexible material with a flat bottom that allows the package to stand upright when resting on the flat bottom, and an upper end opposite to the flat bottom.
  • the upper end can for example correspond to a sealed area so as to close the package.
  • the upper end can also define the opening of the package.
  • the bag of flexible material generally comprises a first face, i.e. a front face, a second face, i.e. a back face, opposite to the first face, and right and left side faces that connect the first face to the second face.
  • this folded element is also known as the "cavaliere", or knight, since from a side view of the package, the first portion and the second portion divided by the folding line can schematically represent the legs of a knight straddling the bag.
  • this element can be called “Kartonreiter”, see for example DE 38 32 275 A1 , or “Kartonst Vietnamese”. In English it can be called “cardboard strip”.
  • This element is particularly advantageous because it allows reporting information on the product contained in the packaging to which it is applied, for example information on the manufacturer of the product contained therein, on the ingredients of the product contained therein, the expiry date and so on. Furthermore, it is possible to display captivating images, trademarks or logos on this element to attract consumer attention. Instead of printing this information directly onto the faces of the bag, whose flexible material may not be a good support for printing, it is possible to print it easily and effectively on this folded element which is generally made of paper, card or cardboard, and is then applied to the bag in order to realise the final package.
  • the object of the present invention is to optimise and further improve such packages.
  • the object of the present invention is to provide packages of this type which are even more versatile and functional than the known packages.
  • the present invention is based on the idea of providing a further container, for example an envelope, interposed and fixed between the bag of flexible material and the folded element. It is possible to store products inside this container that accompany the main product contained in the bag of flexible material. For example, if flour is contained in the bag of flexible material, it may be advantageous to provide yeast in the additional container. If a mix for desserts is contained in the bag of flexible material, it may be advantageous to provide decorative items for desserts in the additional container.
  • the additional container can also be used for gadgets or in any case for any type of product wished to accompany the product contained in the bag of flexible material but which, for whatever reason, is not initially placed in contact or mixed with the product contained in the bag of flexible material.
  • a package comprising a bag of flexible material comprising a first face and a second face, wherein the package further comprises an element folded along a folding line, wherein the folding line is parallel to the upper end of the bag and divides the folded element into a first portion and a second portion so that the first portion extends along the first face and the second portion extends along the second face, wherein the package further comprises a container interposed between the package and the folded element, for example between the first portion and the first face.
  • the bag can be made of any type of flexible material, for example a material compatible with food products.
  • the first face can be the front face of the bag, i.e.
  • the second face can be the back face of the bag, i.e. the face that generally shows further information such as the ingredients of the bag's contents, the nutritional values, the expiry date and so on.
  • the bag could also not present any information or words and all this information could be reported on the folded element.
  • the bag could be closed, for example sealed, in order to avoid the accidental spillage of the product.
  • the bag could be configured to preserve the organoleptic properties of the product contained therein.
  • the bag could be sealed at its upper end.
  • the folded element according to the present invention is generally indicated in English as a "cardboard strip".
  • the folded element can be made of any material suitable for being folded.
  • the folded element can be made of paper, card or cardboard.
  • the first portion of the folded element can report the main information on the contents of the bag, for example the manufacturer's logo, the name of the product, one or more figures representing the product contained therein or that which can be achieved with the product contained therein or so on.
  • the second portion of the folded element can report further information such as the ingredients of the contents of the bag, the nutritional values, the expiry date and so on.
  • the length of the first portion along the first face of the bag could be equal to the length of the second portion along the second face of the bag.
  • the folded element is symmetrical.
  • one of the two lengths could be greater than the other and thus give the folded element an asymmetrical configuration.
  • the container interposed between the bag and the folded element can be advantageously used to contain any type of product wished to accompany the product contained in the bag but which, for whatever reason, is not placed in direct contact with the product contained in the bag within the package.
  • a package wherein the container is an envelope.
  • the envelope is particularly advantageous since it has a flattened shape which is particularly suitable to be interposed between the bag and the folded element.
  • the envelope can be made of any type of material, for example material compatible with food products.
  • the envelope can be hermetically sealed to preserve the properties of the product contained therein.
  • a package wherein the length of the first portion along the first face is greater than the length of the second portion along the second face.
  • This asymmetrical configuration of the folded element is particularly advantageous in the case wherein the container is interposed between the first portion and the first face of the bag, as a larger surface to which the container can be applied is available.
  • a package wherein the folded element further comprises a through hole, for example a euro hole that allows hanging the package, or one or more openings to be able to grasp the package through the one or more openings.
  • the euro hole can be used to hang the package on store shelves.
  • the one or more openings can be used as a handle to be able to grasp the package.
  • a package wherein the first portion and/or the second portion is fixed, for example by means of glue, to the first face and/or to the second face, respectively. It is therefore possible to have a configuration wherein only the first portion is fixed to the first face. Alternatively, it is possible to have a configuration wherein only the second portion is fixed to the second face. Furthermore, it is possible to have a configuration wherein both portions of the folded element are fixed to the respective faces of the bag. Fixing by glue is advantageous because it is a stable fixing and, at the same time, it is not visible from the outside of the package. Furthermore, the use of glue allows avoiding fixing by rivets, which are disadvantageous since they are expensive, difficult to apply and can be accidentally swallowed.
  • a package wherein the container is fixed, for example by means of glue, to the folded element, for example to the first portion of the folded element. Fixing with glue is advantageous because it is stable. Furthermore, fixing the container to the folded element is advantageous since it allows the container to be applied directly to the bag when the folded element is applied.
  • a package is provided wherein the container is fixed, for example by means of glue, to the first face. This allows the container to be further secured to the system so as to effectively prevent the container from accidentally separating from the package.
  • a package wherein the container is interposed between the first portion and the first face, the container is fixed, for example by means of glue, to the first portion and the first portion is further fixed, for example by means of glue, to the first face.
  • the fixing of the first portion to the first face can advantageously take place below the container so that the container is enclosed in the space defined in the vertical direction between the folding line of the folded element and the fixing point between the first portion and the first face of the bag. In this way the accidental detachment of the container from the package is effectively prevented, for example during the transport steps of the package.
  • a package wherein the folded element is fixed to the package by one or more rivets. Even if the rivets could increase the costs of the system and could be accidentally swallowed, the package with rivets could still be desired for aesthetic purposes, for example because the rivets evoke a fixing method of past times or in any case fixing carried out in a manual manner.
  • a package wherein the bag further comprises a flat bottom so that the package can stand upright resting on the flat bottom.
  • a method for making a package of flexible material comprising the following steps:
  • the bag can for example be provided by a machine known from the state of the art for making, filling and closing bags of flexible material.
  • step b) comprises the following sub-steps realised in the order in which they are listed:
  • This method is particularly advantageous since fixing the container to a flat element is particularly simple. In this way the container is automatically fixed to the package in an easy way when the folded element is fixed to the package.
  • step b3) and step c) are carried out simultaneously.
  • Folding and fixing the folded element to the bag at the same time is particularly advantageous because the production times of the package are accelerated and everything can be done in a reduced amount of space.
  • step b1) comprises the following sub-step: b11) applying glue to a surface of the foldable flat element so that a first part of the applied glue can be used to perform step b2) and, following step b3), a second part of the applied glue is in the second portion so as to be able to fix the second portion to the second face and a third part of the applied glue is in the first portion so as to be able to fix the first portion to the first face.
  • step b11 This embodiment is particularly advantageous because with the sole application of glue to the flat element as defined in step b11), all the desired portions of glue are obtained to firmly fix both the container and the folded element to the bag. This allows speeding up and further simplifying the formation of the package and, at the same time, obtaining a stable package.
  • the glue applied in step b11) can be applied using a single glue applicator that applies the three parts of glue at different times.
  • step a) comprises the following sub-step: a1) applying glue to the first face and/or to the second face so that following step c), the first portion is fixed to the first face by at least a first portion of the glue and/or the second portion is fixed to the second face by means of at least a second portion of the glue.
  • the glue for fixing the folded element to the bag is applied directly to the bag.
  • the glue for fixing the container can instead be applied to the foldable flat element.
  • This embodiment provides two distinct glue application stations, one station for applying glue to the bag and one for applying glue to the foldable flat element. This makes it possible to speed up the process because these glue applications taking place in separate stations can occur simultaneously, since one station operates on the bag and the other on the foldable flat element before they are placed in contact.
  • FIG 1 schematically shows a bag 100 that can be used to realise a package according to an embodiment of the present invention.
  • the bag 100 is made of flexible material, for example material compatible with food products that can be stored in the bag 100.
  • the bag 100 comprises a first face 101, in the front in the figure, and a second face 102 opposite to the first face 101 and therefore in the back in the figure.
  • the bag 100 also comprises a flat bottom 104 that allows the bag to stand upright resting on the flat bottom 104.
  • the bag also comprises an upper end 103 opposite the flat bottom 104.

  • the package 1000 comprises a bag 100 such as that shown in figure 1 , a folded element 200 and a container 300, for example an envelope, interposed between the bag 100 and the folded element 200.
  • the folded element 200 (also called "cardboard strip” in English) is folded along the folding line 203 which is parallel to the upper end 103 of the bag 100.
  • the folding line 203 divides the folded element 200 into a first portion 201, visible in the figure, and a second portion 202 placed in the back of the package and therefore not visible in the figure (see, for example, figure 4 ).
  • the first portion 201 extends along the first face 101 of the bag 100.
  • the second portion 202 extends along the second face 102.
  • the container 300 is interposed between the first portion 201 and the first face 101.
  • the container 300 is shown with a dashed line in figure 3 since it is located below the first portion 201. However, the container 300 is outside the bag 100.
  • Figure 4 shows a side view of the bag of figure 3 .
  • the two portions 201 and 202 of the folded element 200 identified by the folding line 203 can be noted.
  • Note also that the length of the first portion 201 along the first face 101 is greater than the length of the second portion 202 along the second face 102. In this way, space is created for housing the container 300 between the first portion 201 and the first face 101.
  • the container 300 is interposed between the first portion 201 and the first face 101.
  • the container 300 is therefore below the folded element 200 but outside the bag 100.
  • Figure 4 also shows that the folded element 200 is fixed to the bag 100 by means of glue.
  • the second portion 202 of the folded element 200 is fixed to the second face 102 of the bag 100 through the portion of glue 501.
  • the first portion 201 of the folded element 200 is fixed to the first face 101 of the bag through the portion of glue 502 which is above the container 300, i.e. between the package 300 and the upper end 103 of the bag 100.

  • the container 300 is fixed to the first portion 201 through the portion of glue 503.
  • the portion of glue 501 is not present but the portion of glue 504 with which the container 300 is fixed to the first face 101 is present.
  • Figure 7 shows a further alternative embodiment.
  • the fixing of the first portion 201 to the first face 101 does not take place through the portion of glue 501 placed above the container 300 but through the portion of glue 505 placed below the container 300, i.e. between the container 300 and the lower end of the first portion 201.
  • Figure 8 shows a further possible variant of the configuration of figure 7 wherein the portion of glue 504 between the container 300 and the first face 101 is added.
  • Figure 9 shows a further possible variant of the configuration of figure 7 wherein the portion of glue 502 is added between the container 300 and the first face 101.

  • the system can comprise a glue applicator 17c configured to apply glue to the lower surface of the foldable flat element 200' extracted from the storage 11.
  • the foldable flat element 200' is placed in a position between the storage 11 and the supporting and folding element 13.
  • the foldable flat element 200' is transported from the second gripping element 12b to a position outside the storage 11, in particular between the storage 11 and the supporting and folding element 13.
  • the conveyor belt 19 is located below this position.
  • one of the containers 300 housed on the conveyor belt 19 is located below this position.
  • glue 503 is applied to the lower face of the foldable flat element 200'.
  • the glue 503 can be applied by means of the applicator 17c, for example a glue gun or the like.
  • the applicator 17c can be configured to apply not only the glue 503 to fix the container 300 to the foldable flat element 200', but also to apply additional glue to the foldable flat element 200' so as to be able to fix the folded element 200 obtained by folding the foldable element 200' along the folding line 203 to the bag 100.
  • the glue can be applied while the foldable flat element 200' is removed from the storage 11. Alternatively, the glue can be applied while keeping the foldable flat element 200' stationary between the storage 11 and the position at the supporting and folding element 13.
  • Figure 21 shows that a supporting and thrusting element 20, for example a suction cup or a pusher movable in a vertical direction, is used to bring the container 300 from the housing onto the conveyor belt 19 until it comes into contact with the foldable flat element 200'.
  • a counter-thrusting element 21 keeps the foldable flat element 200' fixed against the thrust of the element 20 so as to be able to effectively fix the container 300 to the foldable flat element 200' without undesirably displacing the foldable flat element 200' and/or without damaging the foldable flat element 200'.
  • Figure 22 schematically shows a further step of the manufacturing process of a package.
  • the second gripping element 12b has dragged the foldable flat element 200' over the supporting and folding element 13, in particular above the bar 13a.
  • the system 1 further comprises locking means 16 for locking the foldable flat element 200' in contact with the supporting and folding element 13.
  • the locking element 16 comprises a bar which is movable in a vertical direction so as to push the foldable flat element 200' downwards until it contacts the supporting and folding element 13.
  • the lower end of the bar 16 can have a recessed shape so as to be able to better lock the foldable flat element 200' in contact with the supporting and folding element 13.
  • FIG 23 schematically shows a further step of the manufacturing process of a package.
  • the folding means 14 are lowered so as to fold the foldable flat element 200' around the supporting and folding element 13 and fix it to the bag 100.
  • the folding means 14 comprise two series of rollers that can be moved in a vertical direction so that when they are moved downwards they fold the foldable flat element 200' around the supporting and folding element 13 so as to form the folded element 200.
  • the rollers slide along the sides of the folded element 200 so as to make it adhere and then fix it to the bag 100.
  • the fixing of the folded element 200 to the bag 100 can take place by means of the glue applied to the faces 101 and 102 of the bag by the applicators 17a and 17b.
  • the fixing of the folded element 200 to the bag 100 can take place by means of the glue applied to the lower face of the foldable element 200' by means of the applicator 17c configured to apply glue to the lower surface of the foldable flat element 200' when it is extracted from the storage 11.
  • the fixing could also take place through the container 300, to whose surface facing the bag glue could be applied by means of the applicator 17c.
  • the further movement of the housings 15 allows removing the package 1000 from the supporting and folding element 13.
  • the supporting and folding element 13 can be adjustable in height so as to be able to select the desired distance D between the folding line 203 and the upper end 103 of the bag (see figures 1 and 2 ).
  • the housings 15 can also be adjustable in height so as to select the distance D based on the vertical position of the bags 100 housed in the housings 15.
  • the through holes can be made directly on the packages, therefore made as obtained in figure 23 .
  • the through holes can be made by providing the foldable flat elements 200' with suitably positioned pairs of holes so that the holes of the pairs fit together when the foldable flat element 200' is folded along the folding line 203.
  • the foldable flat elements 200' stacked in the storage 11 can already be provided with these pairs of holes wherein the two holes of each pair are suitably positioned in relation to the folding line 203 so that, following the folding along this line, a through hole is obtained.
  • system could further comprise a station for applying rivets 205 to the package so as to fix the folded element to the bag not only by means of glue, but also by means of rivets.
  • This station could be downstream of the station at the supporting and folding element 13.
  • configurations have been shown with only one container 300 interposed between the folded element and the bag, it is possible to realise configurations with more than one container interposed between the folded element and the bag.
  • configurations with a first container between the first portion of the folded element and the first face of the bag and a second container between the second portion of the folded element and the second face of the bag.
  • more than one container for example two, three or four, are arranged between the first portion of the folded element and the first face of the bag, or between the second portion of the folded element and the second face of the bag, or on both sides.
  • the dimensions of the packages and therefore of the relative bags and of the corresponding folded elements can be various, for example to be able to contain from a few grams up to a few kg of product.
  • the dimensions and geometric configurations of the folded element can also be varied.
  • the portions of the first face and/or the second face of the bag covered by the first portion and/or the second portion, respectively, of the folded element can have various dimensions with both symmetrical and asymmetrical configurations possible.
