Description

The scope of the invention

The present invention relates to a container, especially intended for storing food products, and to a method for manufacturing such a container.

The presented invention is applicable in the food industry and is particularly intended for the storage of liquid food products, such as milk, fruit juices, yoghurts, mineral water and others whose chemical and organoleptic properties can be easily impaired.

State of the art

It is common practice for liquid products of the type in question to be poured into containers made of a multilayer material or from processed paper material, such as thick paper or cardboard, coated with at least one layer of an impermeable antiseptic coating, along with others, usually polyethylene.

Typically, these containers are created from flat blanks cut from a roll of continuous material wound around a bobbin. Each workpiece obtained in this way undergoes a scoring operation designed to print fold lines that determine the shape of the container being manufactured.

In particular, on each workpiece after scoring there are longitudinal, transverse and inclined fold lines. The longitudinal bending lines extend generally along the entire length of the workpiece, so they can serve as the basis for the initial bending operation to give the workpiece a substantially tubular shape that can be fixed immediately by sealing or welding along one overlapping longitudinal side edge of the workpiece. The bending transverse lines essentially extend close to the free transverse edges of the workpiece and extend over the entire width of the material so as to determine the boundaries of the two opposite ends, which, in subsequent bending and sealing operations, constitute a closed lower end and upper outlet in the finished container.

The inclined fold lines usually extend through the end parts of the workpiece between the transverse fold lines and the free transverse edges and are intended to facilitate the formation of the lower end and the outlet of the container during manufacture.

As for the operation in which the lower end of the container is formed, it is performed as a whole by folding and folding the corresponding end part in mutually opposite sections of the corresponding transverse fold line. Thus, by using inclined fold lines, the end portion structure can be strengthened in a direction perpendicular to the longitudinal direction of the corresponding container, and initially it has the form of two conjugated and partially overlapping trapezoidal halves.

After bending and folding operations, two trapezoidal halves are welded along the overlap line to create a square central part corresponding to the lower end of the container, on both sides having one side part with a multilayer structure and with a triangular contour, which can be called the corresponding stiffeners in the manufacture of protruding perpendicular to the container body.

The long base of each triangular stiffening element usually coincides with the corresponding portion of the transverse fold line limiting the corresponding end portion, so that the stiffening elements can be bent along the corresponding long bases and folded to the desired position within the contour of the central square part, so that each of them is in a plane substantially parallel to the plane in which this central portion is located. In this case, the stiffeners are directed towards each other, converging to the middle of the central square part.

In this connection, the stiffeners are sealed, whereby they are fixed in the middle of the central square part, thereby completing the lower part of the corresponding container.

Then, the half-assembled container is subjected to the following folding operation, by means of which the upper part is formed, which can also be sealed to form a completely closed configuration or provided with a neck including a removable cover.

While it is known that conventional containers for storing liquid food products create an environment that provides protection against harmful bacterial reagents, the applicant believes that they nevertheless have some drawbacks, mainly related to problems associated with the storage of products without compromising their quality, and the costs of manufacturing and selling containers.

More precisely, the design of such conventional containers and especially the folded bottom end is such that they have at least one intermediate space created by stiffeners and allowing gaps to be present in which unwanted liquids, such as cleaning or flushing liquids, can enter and remain there until the container is filled with liquid food product. Needless to say, in the final analysis, mixing food products with such liquids leads to their irreversible contamination and deterioration in quality.

Attempts to overcome the aforementioned drawback consisted in carrying out a variety of operations, including drying and monitoring the condition inside the container being manufactured. However, these operations lead to a significant increase in production time, as well as to a noticeable increase in manufacturing costs, which are factors that in turn affect the cost of sales of containers.

The purpose of the present invention is to overcome the problems inherent in the prior art by creating a container, in particular, for storing food products, in which there are no intermediate spaces and which has a relatively low cost of manufacture and sale.

SUMMARY OF THE INVENTION

This goal, as well as other goals that will become clear from the following description, are essentially realized according to the invention in a container, in particular for storing food products containing a hollow body, obtained by folding and sealing at least one essentially flat preforms and containing a capacitive part forming a cavity in which at least one product intended for storage is placed and having at least one side wall that has at least one the end part, made possible to bend and seal it with the formation of the lower end, and the output part located on the end opposite the lower end, and is constantly connected to the side wall of the capacitive part and combined with it to form the specified cavity, at least partially wherein the container is characterized in that the lower end made of the end part of the side wall has at least one zone with a layered structure, separated by at least one seam located insulating said zone from the container cavity, so that the cavity encloses a volume in which there are no intermediate spaces and / or stagnation places.

According to another aspect of the invention, the aforementioned objects are realized in a similar manner in a container, in particular for storing food products comprising a hollow body obtained by folding and sealing at least one substantially flat preform and containing a capacitive portion forming a cavity into which placed at least one product intended for storage, and having at least one side wall, which has at least one end part, made with the possibility of its bending and sealing with the formation of the lower end, and the output part located on the end opposite the lower end, and is constantly connected to the side wall of the capacitive part and combined with it to form the specified cavity, at least partially, the container is characterized in that the output part has at least one spout, due to which food products in the container can flow in a preferred predetermined direction and which consists of a portion of the output part formed by two lines bends extending in different directions to the free edge of the outlet part, and can go from an idle state in which the container is closed and the spout is removed into the outlet part and has a substantially flat configuration, to the working state in which the container is open and the spout protrudes from the specified output part, and vice versa.

The objectives of the present invention are also realized in a method for manufacturing a container, in particular for storing food products using a substantially flat preform from a material having bending lines obtained by scoring, including forming the preform substantially tubular with at least one lateral shape the walls of the manufactured container, fixing the workpiece while maintaining the tubular shape, bending the tubular workpiece in at least two mutually opposite sections of the transverse line the bend that bounds the end part of the side wall, ensuring the bending of the end part along inclined bending lines extending from the transverse bending line and converging to the free transverse edge of the tubular workpiece, with the formation of the lower end of the manufactured container and at least two mutually opposite stiffeners with layered structure, fixing the bottom end and stiffeners by welding at least two connected sides of the free transverse edge formed by a tubular zag by otovka, subsequent bending of the end part along mutually opposite sections of the transverse fold line, limiting the stiffeners, providing a flat arrangement of these elements on top of the lower end, and attaching the stiffeners to the lower end, the method is characterized in that it additionally seals the layered structure, formed by each stiffener along a corresponding portion of the transverse fold line.

In the drawings, the item number 1 indicates the proposed container as a whole and, in particular, a container for storing food products.

As shown in FIGS. 1, 3, 4, 5, 7, 9, and 10, the container 1 comprises a container 2 obtained by bending and welding at least one planar blank 1a, which is described below. The container 2 of container 1 includes a capacitive part 3 forming a cavity 4 (FIG. 3), which can be filled with at least one liquid food product, and an outlet part 5, through which the food product located in cavity 4 can be poured or otherwise retrieved.

The capacitive part 3 contains at least one side wall 6 having an end part 7, which, by means of bending and welding operations, can be shaped into the lower end 8, which is located essentially perpendicular to the longitudinal direction of the container 1.

1 and 3-6 depict a first embodiment of the invention in which the preferred geometric shape of the side wall 6 of part 3 is in the form of a substantially prism with a square cross section and with four substantially identical rectangular sides 6a. Also, the end portion 7 (FIG. 3) of the side wall 6 is four sides 7a extending from the respective sides 6a of the side wall 6 in the longitudinal direction of the container 1, without interruption.

7 depicts a second embodiment of the invention, in which, on the contrary, the side wall 6 formed by part 3 of the container 1 is essentially cylindrical with a circular cross section.

Naturally, the description of these two solutions characterizing the shape of the container 1 does not imply any restrictions on the proposed invention, the scope of which includes other forms and embodiments that differ from those presented as an example.

The above output portion 5 extends from the end of the portion 3 opposite the lower end 8 and surrounds the cavity 4 at least partially. More precisely, the outlet part 5 has four sides 5a integrally formed with the side wall 6 and inclined relative to this wall 6 to form an essentially funnel-shaped element in the form of a truncated pyramid, tapering in the direction from the side wall 6.

As shown in FIGS. 1 and 7, the container 1 preferably has at least one mouth of a substantially tubular shape, indicated by the position number 9 and attached to the uppermost edge of the outlet part 5, remote from part 3, and a corresponding closure element or lid 9a, worn on the neck 9 or screwed on it with the possibility of removal, so that the container 1 can be reliably closed.

The scope of the invention is not limited to the image of the neck 9, since the container 1 may also have other devices with which you can close the food product and / or pour it out or otherwise remove it.

Alternatively and with reference to the third embodiment of the invention, the output part 5 of the container 1 can be made as shown in FIGS. 9 and 10, that is, in the form of a familiar top of the pediment, welded together along the raised suture closure 5b extending across the entire container one.

In the example shown in FIG. 10, the outlet portion 5 has fold lines 5c that, when the container 1 is opened, typically by separating and extending to the sides of the connected parts of the means 5b, serve to create a drain nozzle 5d that allows fluid to flow out when it is removed in a given direction.

In particular, the discharge nozzle 5d can transition from an idle state in which the container 1 is closed and the nozzle 5d is folded flat to form means 5b of the output part 5 to an operating state in which the container 1 is open and the nozzle 5d protrudes from the output part 5, forming a profile of a substantially V-shaped cross section, and vice versa.

As for the end face 8, described by way of example with reference to Figs. 4, 5 and 6, it has a substantially square contour over which two mutually opposite stiffeners 10 are made, made from the end portion 7 of the side wall 6, and are attached to them flat shape.

In particular, each element 10 has a layered structure consisting of two layers of material, obtained by folding the end part 7 twice, and has essentially an outline of an isosceles triangle, the base of which coincides with one corresponding side of the end face 8, and the vertex 10b, opposite the base 10a directed towards the middle of this lower end (Fig.6). Each element 10 folded in this way is welded to the end face 8 at least at one point to ensure permanent attachment.

It should be noted that the layered structure of each element 10 is completely closed at the periphery, since the only side remaining first open during the bending operation, by which part 7 of the side wall 6 is bent and flattened, in other words, the base of the triangle 10a is closed with the corresponding welded a seam 10c made along this base 10a (Fig. 5).

Similar to the structure of the end face 8 described above, the end face 8 of the cylindrical container 1 shown in FIG. 7 is a similar structural configuration, preferably obtained by bending and sealing part 7 of the side wall 6 in a similar manner.

As shown in FIG. 2, the blank 1a used in the manufacture of the container 1 shown in FIGS. 1, 3, 4, 5, and 6 has a substantially rectangular contour and several crease lines 11 obtained by scoring.

In more detail, the preform 1a has four longitudinal fold lines 11a extending along the entire length and bounding the sides 5a, 6a and 7a, respectively, of the outlet portion 5, the side wall 6 and the end portion 7 of the side wall.

The preform 1a also has two transverse fold lines 11b extending substantially perpendicular to the longitudinal lines 11a at a small distance from the free transverse edge 12 of the preform. As shown in FIG. 2, the transverse fold lines 11b extend over the entire width of the workpiece 1a, separating the output part 5 and part 7 from the side wall 6 of the container 1.

Moreover, on the blank 1a there is a group of inclined fold lines 11c located on the output part 5 and serving to determine the shape of this part and on the part 7 of the side wall 6.

More specifically, on each side 5a of the output part 5, there are two inclined fold lines 11c extending from the respective intersection points of the transverse line 11b and the corresponding longitudinal lines 11a, and converging to the corresponding free transverse edge 12 of the workpiece. Each inclined line 11c, thus combining with a corresponding longitudinal line 11a, delimits a triangular zone 13, which will be flattened and welded to a corresponding triangular zone 13, bounded by the same longitudinal line 11a and an inclined line 11c located on the adjacent side 5a.

As can be seen in FIG. 2, the inclined lines 11c on the part 7 of the side wall 6 are located only on two sides 7a of this part. In particular, the sides 7a of the end portion 7 having inclined lines 11c are alternately arranged with two sides 7a on which there are no inclined lines 11c.

Similar to the lines described above, the inclined lines 11c of part 7 depart from the corresponding intersection points of the transverse line 11b and the corresponding longitudinal lines 11a, and converge to the corresponding free transverse edge 12 of the workpiece, in this case meeting at this edge 12 and thus restricting the three triangular zones 14 to each of the two sides 7a, which ultimately fold with the creation of the corresponding elements 10.

As shown in Fig. 8, the cylindrical container 1 shown in Fig. 7 is made of a blank 1a without longitudinal fold lines, but with two transverse fold lines 11b of substantially curvilinear and irregular shape, separating respectively the output part 5, the side wall 6 of the capacitive part 3 and the end part 7 of the side wall.

In particular, the transverse line 11b separating the output part 5 of the container 1 extends over the entire width of the workpiece 1a along subsequent curved segments 11d, each of which coincides with the base of the corresponding side 5a of the output part 5. Also, the transverse line 11b defining the side wall part 7 6 extends over the entire width of the preform 1a along subsequent curved segments 11a, each of which coincides with the base of the corresponding side 7a of part 7.

In relation to the output part 5, the blank 1a has a group of inclined fold lines 11c extending from the corresponding connection points of the segments 11d of the transverse fold line 11b and extending to the corresponding free transverse edge 12.

As shown in FIG. 8, two oblique lines 11c extend preferably from each connection point of the segments 11d and extend in different directions to the transverse edge 12 of the workpiece 1a, on both sides of the longitudinal fold line 11a. The longitudinal line 11a is combined with two inclined lines 11c to create the corresponding triangular zones 13, which are then flattened and welded to one another.

When considering part 7 or end 8, it is evident that there is a group of inclined bend lines 11c on the workpiece, extending from the corresponding connection points of the segments 11d of the transverse line 11b and passing to the corresponding free transverse edge 12 of the workpiece 1a.

More precisely, the inclined lines 11c located on the part 7 are present only on two sides 7a of this part and depart in pairs from the corresponding connection points of the segments 11d and converge from these segments, meeting at points coinciding with the corresponding transverse edge 12. The inclined lines 11c, which can be seen in Fig. 8, limit two essentially triangular zones 14 and two zones 14a, having essentially the shape of half an ellipse, arranged alternately, one after another.

In the example shown in FIG. 11, the blank 1a used to make the container 1 shown in FIGS. 9 and 10 seems almost the same as the blank 1a (FIG. 2) used to make the container 1 shown in FIG. 1, at least with respect to the side 6 and part 7.

On the contrary, with regard to the outlet portion 5, the preform 1a has an auxiliary fold line 12a located between the corresponding transverse line 11b separating the outlet portion 5 and the corresponding free transverse edge 12 of the preform. More precisely, the auxiliary line 12a extends substantially parallel to the transverse edge 12, separating the outlet portion 5b, which is sealed to close the container 1.

In this embodiment, the blank 1a also has a group of inclined fold lines 11c located differently from the inclined lines 11c on the output part 5 of the blank 1a shown in FIG. 2. As shown in FIG. 11, on each side 5a of the output part 5 there is a pair of inclined lines 11c extending from the corresponding intersection points of the transverse line 11b and the corresponding longitudinal lines 11a, and converging to the auxiliary line 12a and meeting therewith creating three substantially triangular zones 13.

The preform 1a also has sloping lines 5c extending between the auxiliary line 12a and the corresponding free transverse edge 12, i.e. across the area to be sealed to create a suture closure 5b. As shown in FIG. 11, the inclined lines 5c are located only on two sides 5a of the output portion 5, alternating with two other sides 5a.

More specifically, the inclined lines 5c located in the area of the tool 5b extend substantially diverging pairs to the transverse edge 12 of the workpiece 1a, delimiting the corresponding triangular zones, each of which forms a corresponding drain spout 5d of the container 1. To make each spout 5d essentially V- figurative profile, on the workpiece 1A there is also a central fold line 12b connected to each pair of inclined lines 5c located in the area of the tool 5b. The specified line 12b bisects the zone along the edges of which a pair of oblique lines 5c passes, with the creation of a preferred flow path defined by the spout 5d.

Regarding the method of creating the container 1, the steps of forming the container shown in FIG. 1 are described below as an example. The corresponding preform 1a (FIG. 2) is first bent along the longitudinal lines 11a to create a substantially tubular element (FIG. 3). At this stage, the preform is subjected to a welding operation to secure one overlapping longitudinal edge 15 and thereby fix the tubular shape obtained in the initial bending step. As a result of this, as shown in FIG. 3, the longitudinal lines 11a form four angular edges, together defining the shape of the container 1 at least partially.

After that, part 7 of the side wall 6 is subjected to a subsequent bending operation, which is carried out on mutually opposite sections of the transverse bending line 11b, which serves to create the end face 8 of the container 1, at least partially (Fig. 4).

In more detail, the bending of the part 7 is preferably carried out along the sections of the line 11b coinciding with the sides 7a of this part, on which there are no inclined lines 11c. Thus, these sides 7a are turned inward to the cavity 4 to a position in which they are located essentially perpendicular to the longitudinal direction of the container 1. At this stage, the sides 7a of the part 7, on which there are inclined lines 11c, are forced to deform by displacing the first two sides 7a and bend exactly along these inclined lines 11c. Thus, part 7 assumes a different shape and position than the original tubular shape.

As shown in FIG. 4, the sides 7a of part 7, on which there are no oblique lines 11c, occupy a position in which they are perpendicular to the longitudinal direction of the container 1 and are within the cross-section of the container, their edges connected along the zone indicated by position number 16 coincide with the median plane of the container.

On the contrary, the sides 7a with the inclined lines 11c applied are bent in two places and give them a substantially triangular shape formed by the various triangular zones 14 of the workpiece 1a. These sides 7a are also set in a position in which they are perpendicular to the longitudinal direction of the container 1, but are outside a square cross section.

As can be seen in FIG. 4, the triangular zones 14 are partially connected in the direction coinciding with said zone 16, so that this zone extends continuously in both directions.

Part 7 after bending and folding is sealed by welding, carried out along the connection zone 16 with the formation of the end face 8 and, therefore, part 3 of the container 1, at least partially.

Preferably, the part 7 located perpendicular to the longitudinal direction of the container 1 is subjected to the following welding operation, for geometrically separating the element 10 from the end face 8 of the container (FIG. 5). In more detail, this operation consists in welding together two layers of each element 10 along the corresponding section of the corresponding transverse bending line 11b, in other words along the base 10a of the corresponding triangle. Thus, each element 10 is isolated from the cavity 4, which as a result is an internal space of a prismatic shape in which there are no intermediate spaces or chambers.

After welding of the element 10, part 7 is once again bent along the sections of the transverse line 11b coinciding with the aforementioned bases 10a, so that the elements 10 are folded onto the end face 8 of the container (Fig. 6). In other words, each element 10 is rotated 180 ° relative to the base 10a and is flattened against the bottom of the container, with its apex directed towards the opposite element 10. In this position, the elements 10 are firmly attached to the end face 8 by a subsequent welding operation.

After forming part 3 of the container 1, the output part 5 is also folded and fastened by subsequent folding and welding operations, which for the container 1 shown in FIG. 1 include an additional step of assembling and securing the neck 9 of the output part 5.

So, the problems inherent in the prior art are overcome in accordance with the present invention, and these objectives are duly achieved.

Thus, the proposed container 1 provides the ability to store liquid food products for a long time in the most favorable condition, and not only products in general, but also substances that require careful handling and / or are perishable.

In particular, with the introduction of welds 10c, applied selectively to areas with a layered structure attached to the end face 8, namely, elements 10 formed by folding in half the parts 7 of the side wall 6 and including the intermediate spaces, these spaces can be isolated from the main volume of the cavity 4, and thus, droplets and / or residual traces of undesirable liquids, such as washing liquids, which usually clean the inside of the container 1, or the foodstuff itself, cannot remain in them.

It is clear that by eliminating the risk of stagnation at the bottom of the container, you can do without all the long and expensive procedures associated with inspecting and drying those areas where flushing liquids could linger and contaminate the packaged food product. Therefore, the corresponding production costs, as well as the costs of manufacturing the container 1, are significantly reduced.
