Description

A kind of container and its manufacturing method

technical field

The invention relates to a container, especially a container for storing edible products and a manufacturing method thereof.

The present invention is applicable to edible products, especially suitable for storing liquid edible products, such as milk, fruit juice, yoghurt, mineral water, etc., whose chemical properties and properties that can be identified by sensory are easy to be reduced by adulteration.

Background technique

It is standard practice for liquid products of the type described above to be filled in multi-layered and treated paper materials such as cardboard or cardboard coated with one or more impermeable and sterile coatings , made of containers, and various coatings are typically polyethylene.

Such containers are generally formed by folding and pasting flat blanks which are cut from a continuous strip of web wound on a reel. The blank produced in this manner is creasing, impressing the blank with a number of crease lines along which it can be bent and which define the shape of the container to be produced.

More specifically, in the creasing process, each blank is pressed into longitudinal, transverse and oblique directions of foldable crease lines. The longitudinal foldable indentation lines generally extend over the entire length of the blank. During production, the initial bending operation is performed along these longitudinal foldable indentation lines to make the blank into a roughly cylindrical shape, and then along the A longitudinally overlapping side edge of the blank is taped or welded to secure the cylindrical shape. Two transverse foldable crease lines are generally close to the transverse free edge of the blank and extend across the entire width of the blank material to define two opposite ends, and the bending is carried out along these transverse foldable crease lines. Folding and sealing operations may form a closed bottom end and top outlet portion of the volume to be produced.

An obliquely oriented crease line typically extends obliquely between the transverse crease line and the transverse free edge at the end of the blank, which facilitates shaping the bottom end of the container to be made bottom and top outlet sections.

Regarding the forming operation of the bottom end of the container, the bottom end of the container is generally formed by bending along mutually opposite segments of the transverse foldable crease lines, respectively. In this way, the end structure can be forced perpendicular to the longitudinal dimension of the container by means of the obliquely oriented foldable crease lines, initially appearing as two matching and partially overlapping half-trapezoidal profiles.

After the bending operation, the two half-trapezoidal profiles are sealed along the overlap to form a square central portion corresponding to the bottom end of the container, while forming two protruding parts from opposite sides of the container. Parts of the double-layer structure, these two parts present a triangular profile, roughly perpendicular to the main structure of the vessel under construction, and they will serve as reinforcing members for the bottom end of the vessel.

The longer bases of each triangular reinforcing member typically coincide respectively with a segment of the transverse foldable indentation line defining this end, so that each reinforcing member can be turned over along the longer bases of the two triangles. Folded to a position within the outline of the square central portion so that they lie in a plane substantially parallel to the plane occupied by said central portion. In this case, two triangular-shaped reinforcement members overlie each other on the square central part.

Subsequently, the sealing operation is carried out to each reinforcing member, and they are attached to the central part of the square to reinforce the bottom end of the container, thus completing the bottom end of the container.

The half-finished container is then further bent to form its outlet portion, which can be permanently sealed in a fully enclosed structure, or fitted with a neck, the opening of which is fitted On a removable cover.

While common containers for storing liquid edible products provide an environment that protects the product, it protects the product from harmful bacterial pathogens. However, the applicant believes that those common containers are by no means without certain disadvantages, mainly related to their ability to ensure that their contents do not deteriorate, and to the manufacturing and distribution costs of the containers.

More specifically, the construction of those common containers, especially their folded bottoms, has one or more interstitial spaces formed by the gaps between the reinforcing members of the double layer, which may trap cleaning or flushing fluids Such undesired liquids, and these undesired liquids are trapped in the container until the container is filled with liquid edible products. There is no doubt that these entrapped liquids will eventually get mixed into the liquid edible products, subjecting them to irreversible contamination and deterioration.

Attempts have been made to overcome the above disadvantages, including adding certain steps in the production, such as drying and monitoring the state of the inside of the container. These steps, however, lengthen the manufacturing process and significantly increase production costs, among other factors that affect the cost of goods sold for the container.

The object of the present invention is to overcome the problems of the prior art by providing a container, in particular for storing edible products, in which there will be no interstitial spaces as mentioned above, and which will have moderate production and distribution costs .

With reference to the figures, reference number 1 designates the container of the present invention, in particular a container for storing edible products, in its entirety.

As shown in Figures 1, 2, 3, 4, 5, 7, 9 and 10, the container 1 has a containment structure 2, which can be made by bending and sealing at least one flat blank 1a, which will be described below be explained. The containing structure 2 of the container 1 comprises a containing part 3 and an outlet part 5, the containing part 3 has a housing 4 (see figure 3), which can be filled with at least one liquid edible product, and the outlet part 5 is used for It is used to pour out or extract the liquid edible product in the housing 4 li.

The receiving portion 3 comprises at least one side wall 6, the end 7 of which is configured to form a bottom end 8 substantially perpendicular to the longitudinal dimension of the container 1 by sequentially performing bending and sealing operations.

Fig. 1 and Fig. 3-6 show the first embodiment of the present invention, wherein each side wall 6 of receiving part 3 shows the preferred geometry of a kind of substantially square section prismatic profile, and it has four substantially complete The same rectangular sides 6a. Similarly, the end portion 7 of the side wall 6 (see FIG. 3 ) is shown as having four continuous extensions from each side 6 a of the side wall 6 without breaking, and four faces 7 a extending along the longitudinal direction of the container 1 .

Figure 7 shows a second embodiment of the invention in which, by contrast, the side wall 6 of the containing part 3 of the container 1 has a cylindrical shape of substantially circular cross-section.

Naturally, the description of these two shapes for the container 1 does not mean to limit the container of the invention to these two shapes, but the scope of the invention includes other shapes and embodiments than those described here.

The above-mentioned outlet portion 5 extends from the end of the housing portion 3 opposite to the bottom 8 and constitutes at least a part of the housing 4 . More specifically, the outlet portion 5 has four faces 5a integral with and angled to the side wall 6, which together form a substantially frustoconical shape oblique to the side wall 6. or chimney-like components.

As shown in Figures 1 and 7, the container 1 is preferably equipped with at least one generally tubular neck 9 fixed to the uppermost end of the outlet portion 5 away from the receiving portion 3, and a detachably fastened on or A lid member or cap 9a threaded onto the port of the neck 9 closes the container 1 tightly.

The scope of the invention is in no way limited to the represented shape of the neck 9, since the container 1 is equally suitable to be fitted with other systems enabling the closure of the container and/or the pouring or extraction of the liquid edible product therein.

Alternatively, with reference to a third embodiment of the invention, the container 1 may be provided with an outlet portion 5 as shown in Figures 9 and 10, that is to say with a familiar gable top, which is secured by a seal achieved by a seam closure 5b extending atop the entire transverse dimension of the container 1.

In the example of Figure 10, the spout portion 5 has two foldable crease lines 5c which, when the container 1 is opened by tearing the top seam closure 5b into two connected parts, 5c forms a pouring port 5d, which can guide the liquid to flow out along a predetermined optimal flow direction when pouring out the liquid edible product.

In particular, the pouring spout 5d can be moved between a non-working position and an operative position, in which the pouring spout 5d is folded flat to become the top seamed closure structure 5b of the outlet portion 5, at which time the container 1 is closed; and In the working position, the pouring spout 5d protrudes outwardly from the outlet portion 5 to form a substantially V-shaped flow path in section, when the container 1 is opened.

In the case of the bottom end 8 exemplified with reference to Figures 4, 5 and 6, it is of generally square profile on which two mutually opposing reinforcing members 10 are obtained by folding and flattening the end 7 of the side wall 6 .

In particular, each reinforcement member 10 is a double-layer structure consisting of two material thicknesses, formed by folding the ends 7 in double layers, and has a substantially isosceles triangular profile, the base 10a of which coincides with A corresponding side of the bottom end 8, the apex 10b of the triangle facing the bottom edge 10a is towards the middle of the same bottom end (see FIG. 6). Once folded in this position, each reinforcing member 10 is affixed to the bottom end 8 at one or more points to ensure a permanent bond.

It can also be seen that since only one side is left open during the initial bending operation of folding and flattening the end 7 of the side wall 6, in other words, the base 10a of the triangle is sealed along this side with the sealant 10c. The bottom edge is closed (see FIG. 5 ), and the periphery of the double-layer structure of each reinforcement member 10 is completely closed.

Similar to the structure of the above-mentioned bottom end 8, the bottom end 8 of the cylindrical container 1 shown in FIG. And made.

As shown in Figure 2, the blank 1a used to make the container 1 of Figures 1, 3, 4, 5 and 6 is generally rectangular and has a plurality of foldable crease lines 11 formed in the creasing operation.

In detail, the blank 1a has four longitudinal foldable crease lines 11a extending along its entire length and defining respectively the faces 5a, 6a and 7a of the outlet portion 5, the side wall 6 and the end 7 of the side wall 6 .

The blank 1a also has two transverse foldable lines 11b which are approximately perpendicular to the longitudinal foldable lines 11a and which are at a short distance from each transverse free edge 12 of the blank. As can be seen in FIG. 2 , the transverse foldable crease line 11 b extends over the entire width of the blank 1 a, demarcating the outlet portion 5 and the end portion 7 of the container 1 from the side wall 6 .

In addition, the blank 1a has a set of obliquely oriented foldable creasing lines 11c, some on the exit portion 5 for defining the shape of this portion, and some on the end portion 7 of the side wall 6.

More specifically, each face 5a of the outlet portion 5 has a pair of obliquely oriented foldable crease lines 11c extending from respective intersections of the longitudinal foldable crease lines 11a and the transverse foldable crease lines 11b to and intersecting on the free transverse edge 12 of the blank. Thus, each foldable crease line 11c and an associated longitudinal foldable crease line 11a together define a triangular area 13 which is flat and sealed to the same longitudinal foldable area formed by the adjacent face 5a. A triangular area 13 defined by the crease line 11a and the crease line 11c in the oblique direction.

It can be seen from FIG. 2 that the oblique direction foldable creasing line 11c on the end portion 7 of the side wall 6 only exists on the two surfaces 7a of this portion. To be precise, there is a surface 7a without the oblique direction folding crease line 11c between the two surfaces 7a of the end portion 7 having the oblique direction folding crease line 11c.

Like the creasing lines already described, the oblique direction crease lines 11c of the end portion 7 are free from the intersections of the longitudinal crease lines 11a and the transverse crease lines 11b close to each other in the transverse direction of the blank. Edge 12 extends. In this case, however, they intersect on a transverse line inside the transverse free edge 12 and divide both faces 7a with oblique direction foldable indentation lines 11c into three triangular regions 14, which The regions will eventually be folded over to form each reinforcement member 10 .

Referring to Fig. 8 and Fig. 7, the cylindrical container 1 is made of a blank with no longitudinal foldable indentation line but two irregular wavy transverse foldable indentation lines 11b, and these two indentation lines respectively define The outlet part 5 , the side wall 6 of the receiving part 3 and the end 7 of the side wall 6 .

In particular, the transverse foldable crease lines 11b defining the outlet portion 5 of the container 1 extend across the entire width of the blank 1a along end-to-end arcuate segments 11d each of which will form the outlet portion 5. The bottom edge of each face 5a. Similarly, the transverse foldable indentation lines 11b defining the ends 7 of the side walls 6 of the container 1 extend across the width of the blank 1a along respective end-to-end arcuate segments 11d each of which will form an end portion 11d. The bottom edge of each surface 7a of the part 7.

As far as the outlet portion 5 is concerned, the blank 1a has a set of oblique direction foldable indentations 11c extending from the intersection of end-to-end arcuate segments 11d of the transverse foldable indentations 11b towards the associated transverse free edge 12 .

As shown in Figure 8, two oblique direction foldable crease lines 11c extend away from each other from the intersection point of each arc segment 11d to the transverse free edge 12 of the blank 1a, and respectively extend along the short longitudinal foldable crease lines. One side of 11 a meets the transverse free edge 12 . Each short longitudinal foldable crease line 11a together with two oblique direction foldable crease lines 11c form each triangular area 13 which will eventually be flattened and sealed against each other.

Turning now to end 7 , or bottom end 8 . The blank has a set of obliquely oriented foldable crease lines 11c extending from the intersection of end-to-end arcuate segments 11d of transverse foldable crease lines 11b towards the associated transverse free edge 12.

More precisely, the bevel direction foldable indentation lines 11c of the end portion 7 only exist on the two faces 7a of this part, and they are formed in pairs from the intersection point of each circular arc line segment 11d connected end to end from the same circular arc. The line segments initially extend close to each other and intersect at the transverse free edge 12 . It can be seen from FIG. 8 that the foldable creasing lines 11c in the oblique direction define two substantially triangular regions 14 and two substantially semi-elliptical regions 14a, which are arranged alternately with each other.

In the example of FIG. 11, the blank 1a used to make the container 1 of FIGS. 9 and 10 appears to be identical to the blank 1a (see FIG. 2) used to make the container 1 of FIG. This is the case for the end 7 .

As far as the outlet portion 5 is concerned, the blank 1a, by contrast, has an auxiliary foldable crease line 12a (see FIG. Between the edges 12. More precisely, the secondary foldable creasing line 12a is substantially parallel to the transverse free edge 12, delimiting the region 5b of the outlet portion 5 (see FIG. 1 ), which is finally taped to close the container 1 .

In this type of embodiment, the blank 1a also has a set of obliquely foldable indentations 11c, which are located differently from the bevelly foldable indentations on the outlet portion 5 of the blank 1a shown in FIG. Line 11c. As shown in FIG. 11, each face 5a of the outlet portion 5 has a pair of oblique direction foldable crease lines 11c extending from each intersection point of the transverse foldable crease line 11b and the corresponding longitudinal foldable crease line 11a to both sides. Intersecting the auxiliary foldable crease lines 12a, in this way divides each face 5a into three generally triangular regions 13.

The blank 1a also has an oblique direction foldable crease line 5c extending between the auxiliary foldable crease line 12a and the associated transverse free edge 12, that is to say, through the portion to be sealed to form a seam closure 5b of that area. It can be seen from Fig. 11 that only the two surfaces 5a of the outlet part 5 have oblique direction foldable indentation lines 5c, and there is a surface without oblique direction foldable indentation lines 5c between these two surfaces 5a. 5a.

More precisely, the oblique direction foldable creasing lines 5c in the region of the seam closure portion 5b extend in pairs substantially away from each other towards the transverse free edge 12 of the blank 1a, in this way defining Several triangular areas, which will form the pouring spout 5d of the container 1 . In order to make each spout 5d have a substantially V-shaped profile, the blank 1a also has a central foldable crease line 12b located between each pair of obliquely directed foldable crease lines 5c. The two central crease lines 12b bisect the area between the pair of oblique direction crease lines 5c, thereby establishing an optimal flow path for the spout 5d.

Regarding this method for making the container 1, the steps of making the container shown in FIG. 1 are illustrated below. Firstly, the relative blank 1a (see FIG. 2) is bent along the longitudinal foldable crease line 11a to form a substantially square cylindrical component (see FIG. 3). At this point, the blank is subjected to a sealing operation to seal the overlapping longitudinal edges to each other, thus securing the cylindrical shape formed by the initial bending step. As a result of this step, it can be seen from FIG. 3 that the longitudinal foldable creasing lines 11a have become four ribs which have at least partially established the shape of the container 1 .

The ends 7 of the side walls 6 are then folded along mutually opposite segments of the transverse foldable crease lines 11b, thereby at least partially forming the bottom end 8 of the container 1 (see FIG. 4 ).

More specifically, it is preferable to bend the end portion 7 on the line segment of the lateral foldable crease line 11b of the face 7a without the oblique direction foldable crease line 11c, and to fold the two faces 7a inwardly to A position substantially perpendicular to the longitudinal dimension of the container 1 . In this step, the two surfaces 7a of the end portion 7 with oblique direction foldable indentation lines 11c are deformed by the displacement of the aforementioned two surfaces 7a without oblique direction foldable indentation lines 11c , and finally bend along those oblique directions along the creasing lines 11c. In this way, the end portion 7 assumes a contour and a state different from the original cylindrical shape.

As shown in Figure 4, the two faces 7a of the end portion 7 without the oblique direction foldable creasing line 11c are in a position perpendicular to the longitudinal dimension of the container 1 and are within the cross-sectional area of the container 1, their The edges join and coincide with the central plane of the container 1 along a seam area indicated by reference "16".

In contrast, the two faces 7a that have been stamped with obliquely directional foldable crease lines 11c are folded in half so as to assume the substantially triangular shape formed by the triangular regions 14 of the blank 1a. These two faces 7a also become substantially perpendicular to the longitudinal dimension of the container 1, but outside the square section of the container.

It can be seen from FIG. 4 that the two triangular regions 14 are partially joined in a direction coincident with the aforementioned seam region 16 , so that this seam region extends continuously between the two sides.

After the ends 7 have been bent and folded flat, the bottom end 8 of the container 1 and thus the accommodating part 3 can be at least partially formed along the seam area with a sealing glue that is airtightly secured.

Advantageously, such ends 7 perpendicular to the longitudinal dimension of the container 1 are subjected to a further sealing operation to geometrically isolate the gap space of the two reinforcement members 10 from the bottom end 8 of the container 1 . More precisely, this operation consists in sealing the two layers of material of each reinforcing element 10 together along the respective segments of the corresponding transverse foldable crease lines 11b, ie along the bases 10a of the respective triangles. In this way, each reinforcement member 10 is isolated from the casing 4 of the container 1, so that a substantially prismatic inner space is formed in the casing without any gap spaces or blind seams.

After the reinforcement member 10 has been sealed, the end portion 7 is bent along the line segment of the transverse foldable crease line 11b coincident with the above-mentioned bottom edge 10a, and the reinforcement member 10 is turned over on the bottom end portion 8 of the container 1 ( See Figure 6). In other words, each reinforcing member 10 is turned over 180° around its respective bottom edge 10a to be flattened on the bottom end 8 of the container 1, and the vertices of the two reinforcing members 10 are aligned with each other. In this position, the reinforcement member 10 is permanently fixed to the bottom end 8 by further sealing.

After shaping the receiving portion 3 of the container 1, the spout portion 5 is similarly folded and secured by further bending and sealing operations, which in the case of the container 1 of FIG. 1 include fitting and securing the neck 9 to the spout. Additional steps for section 5.

The present invention can overcome the problems existing in the prior art, and the above objects can be fully realized.

Firstly, the container 1 of the present invention is able to ensure that liquid edible products are in optimum condition for a long time, not only liquid edible products in general, but especially sensitive and/or perishable liquid edible products as well. In particular, a sealant 10c is selectively applied to the area of the double structure associated with the bottom end 8, that is to say the reinforcing member containing the interstitial space formed by folding the end 7 of the side wall 6 into double layers. 10 is sealed with a sealant to isolate those gap spaces from the body volume of the housing 4, which prevents liquids such as cleaning fluid used to clean the interior of the container 1 or the liquid edible product itself from remaining in the gaps in space.

Clearly, the very time-consuming and costly process of inspecting and drying those crevice spaces of the containers can be dispensed with since the risk of liquid remaining at the bottom of the containers is eliminated. And if there are interstitial spaces communicating with the main body volume of the container, those spaces will trap flushing liquid and the like and contaminate the packaged liquid edible product. Therefore, adopting the present invention can greatly reduce the production cost of the container, and can also reduce its sales cost.
