CONTAINER FOR FRUIT AND VEGETABLE PRODUCTS AND METHOD FOR MAKING THE CONTAINER AND FOR PACKING SUCH PRODUCTS
A container for fruit and vegetable products includes one closed mesh casing for storing products, and one shaped band including one first end portion and one second end portion associable with the respective ends to the mesh casing, and one narrower intermediate portion for connecting between the first end portion and the second end portion, the intermediate portion for connecting between the first end portion and the second end portion, the intermediate portion making a hand grip for the user, so as to allow optimal visibility of the fruit and vegetable products packed and easy and safe transportation thereof.
The present invention relates to a container for fruit and vegetable products and method for making the container and for packing such products.
In particular the present invention relates to a container for fruit and vegetable products that allows optimal visibility of the products themselves contained in it, and at the same time allows it to be easily and safely transported by the user.
STATE OF THE ARTThere are known containers for fruit and vegetable products, suitable for containing products of various kinds like for example potatoes, tubers in general, onions, and yet more, generally consisting of mesh portions associated with extended portions of film made from synthetic material.
The mesh and film portions can be associated with each other for example through welding, or even gluing, crimping, or in yet other ways.
The film portions display information of various kinds, like for example concerning the goods, nutrition, storage and expiry date of the products, and the like, as well as writing and commercial data, producer's logos, and yet more data.
However, containers of this known type, due to the aforementioned extended film portions, do not allow the products contained inside them to be seen clearly, in this way preventing the user from checking the appearance, the integrity or the cleanliness of the fruit and vegetable products.
In many cases, containers do not have adequate handgrip portions for the user, making them awkward to transport; in other cases the existing containers instead have handles specially made in the processing steps, which obviously lengthens the production times, also worsening the final costs of the containers themselves.
Spanish utility model ES1027802U teaches, for example, a bag with mesh casing and a label that has a first strip element extending from one end of the bag to the other and externally opposite the rear face of the bag, as well as a second and a third strip element each arranged externally opposite the front face of the bag and each welded to a respective portion of the first strip element with interposition of the ends of the bag, said ends thus being clamped one between the first and the second strip element welded together and the other between the first and the third strip element welded together.
The European patent application with publication number EP2535281A1, on the other hand, teaches a bag with mesh casing and a label having two elements arranged on opposite sides to one another with respect to the bag and connected together at the ends of the casing, so that both the ends are locked between the two strip elements.
Bags with structures similar to those indicated above are taught by EP2210735A1, U.S. Pat. No. 5,912,197, WO2011034038A1.
In order to obtain all of the bags according to the patent documents mentioned above, it is necessary to use a substantial amount of material for the label, taking into account, furthermore, the fact that it is necessary to foresee label elements or components arranged on opposite sides to one another at the two ends of the bag and, also for this reason, the packing and fastening procedure of the label to the casing involves a series of complex steps that are expensive to carry out.
SUMMARY OF THE INVENTIONThe technical task of the present invention is therefore to devise a container, such as a bag for fruit and vegetable products and method for making the container and packing the such products, which allows optimal visibility of the products contained inside it, so as to allow the user to easily and quickly check the appearance, the integrity and the cleanliness of the products themselves, still displaying all the necessary information and data.
In such a technical task, a particular purpose of the present invention is to make a container for fruit and vegetable products that can be easily and safely transported by the user.
A further purpose of the present invention is to devise a method for making the container and packing such products that requires simple and quick processing steps, cutting production times and costs.
Another purpose of the present invention is to provide a new bag as stated above having an amount of material for a band or band component, such as a label, that is less than the solutions proposed previously.
This task and this purpose are accomplished by the container for fruit and vegetable products according to the present principles.
The container for fruit and vegetable products comprises at least one closed mesh casing for storing the products, and at least one shaped band comprising at least one first end portion and at least one second end portion suitable for being associated with the respective ends to the mesh casing; the shaped band also comprising at least one narrower intermediate portion for connecting between the first end portion and the second end portion, such an intermediate portion is suitable for making a handgrip for the user, so as to allow optimal visibility of the fruit and vegetable products packed and easy and safe transportation thereof.
Further advantageous characteristics are described herein.
The characteristics of the invention will become clearer to any man skilled in the art from the following description and from the attached tables of drawings, given as a non-limiting example, in which:
With reference in particular to the attached
The container 1 for fruit and vegetable products A comprises at least one closed mesh casing 2 for storing the products A.
The container 1 also comprises at least one shaped band 3.
The mesh casing 2, if so desired having a substantially tubular body, includes a first face 2a1, a second face 2a2 and two side walls 2b and 2c.
According to the present invention, the shaped band is fixed solely to the first face 2a1 of the container, whereas the second face 2a2 is free or not engaged or in contact with the band 3.
The tubular body comprises a first end 2d and a second end 2e each defined between respective end sections 2f, 2g (
Preferably, the shaped band comprises at least one first end portion 4 and at least one second end portion suitable for being associated with the respective ends to the mesh casing 2.
Even more preferably, the shaped band 3 also comprises at least one intermediate portion 6, if so desired narrower for connecting between the first end portion 4 and the second end portion 5.
The intermediate portion 6 is suitable for making a hand grip for the user, so as to allow optimal visibility of the fruit and vegetable products A packed and easy and safe transportation thereof.
In particular, at least one from the first end portion 4 and the second end portion 5 defines at least one extended surface 7 suitable for the application of writing, logos and the like, as represented in
In a possible solution, represented in
In particular, the ends of the first end portion 4 and of the second end portion 5 of the shaped band 3 are associated with respective ends of the mesh casing 2.
The shaped band 3 and the mesh are preferably made from synthetic material, so that at least the ends of the first end portion 4 and of the second end portion 5 can be associated through welding with the mesh casing 2.
Moreover, for example in the case in which a particularly thin mesh is required, the shaped band 3 can be associated with the mesh casing 2 through welding at least of the ends of the first end portion 4 and of the second end portion 5 to the mesh itself, if so desired, with the interposition of respective pieces made from strengthening synthetic material. Such a solution is not represented in the figures.
The casing 2 and/or the band 3 at the respective attachment area can be flat, as illustrated in
In this version, the casing 2 and/or the band 3 have a substantially corrugated or undulating configuration, so that the contact surface between them is greater than that between two contact portions (of the band and of the casing) that are both substantially flat.
Moreover, the band, in particular at the attachment area, could have a substantially corrugated configuration, so as to comprise, from one side wall to the other of the bag, raised portions 3a alternating with recessed portions 3b.
It should be noted that the raised portions 3a define convexities facing towards the end sections 2f, 2g of an end 2d, 2e of the container or bag, whereas the recessed portions 3b define concavities facing towards the end sections 2f, 2g of an end 2d, 2e of the container, so as to have an attachment area that has a greater extension than an attachment area that lies entirely on one same plane and also shaped attachment portions so as to increase the stability and secureness of the attachment.
Concerning this, the raised portions 3a and/or the recessed portions 3b can comprise V-shaped sections (see
The raised portions 3a of a band component or label can, in use, be housed in, and welded to respective hollow portions 3c of a first end section 2f of an end 2d, 2e of the casing, whereas the recessed portions 3b of a band or label can, in use, be housed in, and welded to respective projecting portions 3d of a first end section 2f of an end 2d, 2e.
The hollow portions 3c of an end section 2f will, in this case, alternate with projecting portions 3d thereof.
According to a version of the present invention, the hollow portions 3c will in turn be housed in, and welded to respective channel portions 3e of the other or second end section 2g of an end 2d, 2e, whereas the projecting portions 3d of a label are, in use, welded to respective projecting portions 3f of the other or second end section 2g of an end 2d, 2e.
The channel portions 3e of an end section 2g will alternate with projecting portions 3f thereof.
Preferably, between band or rather between the intermediate portion 6 and the first face 2a1, see
The band can, of course, have a different width or length.
In a container according to the present invention, as will be understood, it is possible to use a smaller amount of label/labels than the solutions presented earlier, taking into account the fact that it has one or more bands, each fixed just on one face, first (front) or second (rear if so desired), or rather just on one face of one or both of the ends 2d, 2e of the container or bag itself.
This is possible in particular precisely due to the characteristic according to which the attachment area of the label to a respective face of the mesh casing is not flat or in any case does not lie in a single plane, but has raised portions 3a and recessed portions 3b and, if so desired, hollow portions 3c and projecting portions 3d, channel portions 3e and projecting portions 3f, which make it possible to obtain a larger contact surface and with suitably shaped sections so as to improve the anchoring or attachment with respect to bags with conventional labels that, indeed, have a substantially flat surface or attachment area.
If so desired, a container according to the present invention could comprise one or more bands 3, each fixed solely at an end 2d or 2e of the mesh casing (see
Therefore, in such a second case, the band component or label 3 would be detached or in any case not fixed to the mesh casing 2 in the portions of the first face 2a1 for connecting between the top and bottom ends 2d, 2e.
Alternatively, the mesh casing 2 could be folded upon itself, or undulated, or rolled up, at the attachment end to the band so as to still allow a contact surface to be obtained between them that is larger than that between two contact portions (of the band and of the casing) that are both substantially flat.
According to a further version (not illustrated) of the present invention in the lower part of the casing 2, substantially at the second face 2a2, it is possible to insert a sheet of soft material, or bubbled material, which allows the most delicate fruit and vegetable products to be protected.
Hereafter we will describe the method for making the container 1 and for packing such products A, according to the present invention.
The method comprises the steps of providing at least one mesh made from synthetic material, feeding the products A to be packed into the mesh, welding the mesh so as to enclose the products A, cutting the mesh so as to make the aforementioned closed mesh casing 2, associating at least one shaped band 3 with the mesh casing 2 through welding. In the case of the container of
In particular, the quoted steps of welding the mesh so as to enclose the products A and of welding at least the ends of the first end portion 4 and of the second end portion 5 to the mesh can take place in a single operating step.
In greater detail, the method can comprise the step of providing a mesh of the flat type, for example taken from a storage reel, arranging the mesh around a tubular element with the side edges overlapping, welding it at such edges so as to give it a tubular structure, feeding the products A to be packaged, welding the mesh so as to enclose the products A, cutting the mesh so as to make the closed mesh casing 2.
In the case in which it is required for example to use a particularly thin flat mesh, the step of welding the edges of the mesh wound on the tubular element can take place with the interposition of a strip 8 of strengthening synthetic material, to ensure the hold of the weld itself, as illustrated for example in the solutions of
Otherwise, the flat mesh can comprise a side edge previously associated with a strip of synthetic material, and once arranged around the tubular element with at least the quoted strip overlapping the other free side edge, it is welded at at least the strip and at the other free edge, so as to give it a tubular structure.
The welding can take place by overlapping just the strip and the free side edge, or overlapping the strip with the respective edge associated with the free side edge.
Or even both of the side edges of the flat mesh can be associated in advance with respective strips of synthetic material, and once the mesh has been arranged around the tubular element with at least the strips overlapping, it is welded at at least such strips so as to give it a tubular structure.
The welding can take place by overlapping just the strips, or the strips and an edge or both edges of the mesh.
Alternatively it is possible for a mesh to be provided directly already of the tubular type, also stored in a respective reel.
The solutions comprising the strips are not represented in the figures.
Preferably, a method for obtaining a bag according to the present invention can also comprise an attachment step, such as welding or thermowelding of the band or label on the casing 2 so as to obtain a sequence of raised portions 3a alternating with recessed portions 3b, as well as, if so desired, hollow portions 3c and projecting portions 3d and/or channel portions 3e and projecting portions 3f.
Concerning this, it is possible to use a welding group 11, if so desired a welding and cutting group 11 as illustrated in
Such a group comprises a pair of half-bodies or jaws 12, 13 able to be moved apart/together, for example through suitable motor means and each having a respective first 14 and second 15 abutment front. The abutment fronts 14, 15 define the welding and cutting area WCZ of the casing 2 (
From one side, for example the top, to the other, for example the bottom, the abutment front 14 can comprise a first welding section 14a, thus a housing recess 14b in which it is possible to fix a blade or knife 16 that projects, in use, with respect to the abutment front 14, and finally a second welding section 14c, for example substantially aligned with the first section 14a.
The abutment front 15, on the other hand, can comprise at least one welding section configured, in use, to abut and engage a respective welding section of the first abutment front.
The second abutment front, from one side, for example top, to the other, for example bottom, can comprise a first welding section 15a configured, in use, to abut and engage the first welding section 14a, therefore a housing recess 15b, configured, in use, to receive the blade or knife 16, and finally a second welding section 15c, for example substantially aligned with the first section 15a and configured, in use, to abut and engage the second welding section 14b.
As it has been possible to observe, at least one welding section 14a, 15a, 14c and 15c has a configuration having raised portions, for example V or U-shaped alternating with recessed portions, for example V or U-shaped.
When the half-bodies 12, 13 are positioned close together, the raised portions of the welding section 14a or 14c of the first abutment front 14 can shape-engage recessed portions of a respective welding section of the second abutment front 15a or 15c, whereas the raised portions of the welding section 15a or 15c of the second abutment front 15 shape-engage recessed portions of a respective welding section 14a, 14c of the second abutment front 14. The configuration with raised and recessed portions of one or more welding sections, makes it possible, as will be understood, to obtain the corrugated configuration—raised portions 3a and recessed portions 3b—indicated above of the band component or of the label 3, as well as, if so desired, the hollow portions 3c, the projecting portions 3d, the channel portions 3e and the projecting portions 3f of the end sections 2f, 2g.
It is also possible to envisage suitable heating means (not illustrated in the drawings) of one or both of the abutment fronts 14, 15.
With such a group, the casing to be welded as well as the band component or label 3 to be fixed to it are fed between the two abutment fronts 14 and 15 until one end, for example the bottom 2e, of the casing 2 is at the level of the first welding sections 14a and 15a of the group. At this point the group is commanded to close or the two jaws 12 and 13 are commanded to come together, so as to weld the bottom end 2e of the casing and in this way obtained the bottom of a respective bag 1. Possibly, in such a step, it is possible to feed a band or label 3 between the casing and one of the welding sections 14a and 15a, so as to weld or thermoweld it to the bottom of the bag.
Thereafter, the welding and cutting group 11 is commanded to open or the half-bodies or jaws 12, 13 are commanded to move apart, and the casing 2 with the bottom end 2e welded is made to move in steps, with any suitable means, such as belts or rollers or by acting (pulling) on the bottom of the casing, until the top end 2d of the casing is at or at the level of the welding sections 14c and 15c.
At this point, the loose products to be packed are fed into the casing with bottom or lower end 2e closed and, thereafter, the group is commanded to close or the two jaws 12 and 13 are commanded to move together, so as to weld the upper end 2d of the casing and in this way obtain the closed top of a respective bag. Possibly, in such a step it is possible to feed a band or label between the casing 2 and one of the welding sections 14c and 15c, so as to weld it to the top of the bag. If, moreover, a label had been welded to the bottom of the bag that is now closed at the top, during such a welding step of the top of the bag it is possible, if so desired, to fix the other end of the label 3 fixed to the bottom of the bag to the top end of the bag. In order to do this, suitable means for holding and guiding the label must of course been provided.
As can be understood, thanks to the presence of welding sections 14a and 15a and/or of welding sections 14c and 15c configured as stated above (raised portions alternating with recessed portions), it is possible to obtain the welding or attachment of a band or label to a casing only at a face thereof and at one or both ends, without however engaging the connecting portion or section between the ends of the casing.
Such a provision, as we have said, makes it possible to widen and improve the attachment or welding area of the band or label to the mesh casing with respect to the solutions proposed up to now and thus to avoid envisaging band or label portions arranged on both sides or faces of the casing and welded to one another with interposition of the casing or rather of the ends thereof. Such portions are necessary in the prior solutions proposed to ensure a good seal or in any case firm and stable anchoring of the label to the casing.
The way of using the container for fruit and vegetable products 1, according to the invention is, according to what is described, totally intuitive.
As seen, the particular configuration of the shaped band 3, with the narrower intermediate portion 6 (if provided), and the first end portion 4 and the widened second end portion 5, leaves large areas of the mesh casing 2 in view, allowing the user to see the fruit and vegetable products A packed inside in an optimal manner.
It should be noted how on the shaped band 3 it is possible to display (in particular on the surfaces 7, but also on the intermediate portion 6) any information concerning the goods, nutrition, storage and expiry date of the products, and the like, as well as writing and commercial data, producer's logos, and yet more data.
Moreover, the intermediate portion 6 of the shaped band 3 constitutes a safe and easy handle for the user, so that they can transport the container 1 with the packed products A easily and without the risk of it breaking, also thanks to the possible presence of tissues, and/or strips 8 and strengthening strips, suitably welded as needed as described earlier.
As seen, the hand grip for the user is made directly and simply thanks to the intermediate portion 6 of the band 3 suitably associated with the mesh casing 2, without additional processing steps of the container 1 being carried out, as happens, on the other hand, for known types of containers.
Thanks to a bag and to a method for obtaining it according to the present invention it is moreover possible to obtain a substantial reduction in the material of the band or label used to make a container or bag, at the same time obtaining an anchoring of the label to the mesh casing that is just as reliable and firm as, if not better than, prior solution.
The invention, thus conceived, makes it possible to obtain important technical advantages.
An important technical advantage consists of the fact that the container 1 for fruit and vegetable products A allows optimal visibility of the products contained inside it, so as to allow the user to easily and quickly check the appearance, the integrity and the cleanliness of the products A themselves.
As seen, the container 1 can also be transported easily and safely by the user, thanks to the hand grip made through the intermediate portion 6 of the shaped band 3.
The method for making the container 1 and for packing the products A requires, as seen, simple and quick processing steps—including those for obtaining the hand grip—thus allowing advantages in terms both of reduction of production time and costs.
It has thus been seen how the invention achieves the proposed purposes.
The present invention has been described according to preferred embodiments, but equivalent variants can be devised without departing from the scope of protection offered by the following claims.
