Description

  The present invention relates to an injectable aseptic food container.

  A sterile container (for example, an injectable food container such as fruit juice) is a continuous strip of packaging material consisting of multiple layers of different materials (typically heat-seal plastic materials such as paper, aluminum, and polyethylene) Can be obtained starting from It is processed on a dedicated automatic machine.

  The dimensions of such a container are determined so as to accommodate the amount of product used by the user within a predetermined period.

  After opening for the first time, it is often necessary to check the level of food in the container.

  Therefore, in some aseptic containers, a window hole is provided in the packaging material, and the window hole is closed with a layer of transparent material (polyethylene). Such a window hole is arranged in the central portion of the side wall of the container so as to occupy at least 1/3 of the area of the side wall so that the user can easily adjust the inside of the container.

  However, this solution does not ensure the integrity of the container, which can be damaged during or after manufacture. In fact, the presence of the transparent window described above makes the packaging material for manufacturing the container quite weak.

  Furthermore, due to the presence of the window described above, the window expands and a considerable amount of light is incident on the inside of the container. Therefore, the food in the container is adversely affected by the incident light, and the chemical and physical properties of the food are changed.

  The problem to be solved by the present invention is to eliminate the above-mentioned drawbacks.

  The problem to be solved by the present invention can be solved by the injectable aseptic food container described in the claims.

  The container according to the invention is advantageous because the amount of food in the container can be adjusted and at the same time damage to the packaging material and excessive incidence of light can be avoided.

It is a front view in the 1st operation position of the injectable aseptic container for foodstuffs by preferable embodiment of this invention. It is a front view in the 2nd operation position of the container of FIG. It is a top view of the sheet | seat for obtaining the injectable aseptic container for foodstuffs by this invention. FIG. 4 is a perspective view showing another embodiment of an injectable aseptic food container according to the present invention. FIG. 6 is a perspective view showing still another embodiment of an injectable aseptic food container according to the present invention. It is a top view of the sheet | seat and cover strip for obtaining the injectable aseptic container for foodstuffs by embodiment of this invention.

  Further advantages of the present invention will become apparent from the following description given with reference to the accompanying drawings.

  1-3, the code | symbol 1 has shown the aseptic container for foodstuffs which can be inject | poured by this invention.

  The injectable aseptic container 1 for food has a deployment axis H extending in the longitudinal direction D (see FIGS. 1 and 2).

  The container 1 has a bottom wall 2 that faces in a lateral direction with respect to the deployment axis H (when the container 1 becomes usable, the bottom wall 2 is disposed so as to contact a plane), and a bottom wall 2 A side wall 3 in contact with the bottom wall 2 and at least one top wall 4 facing the bottom wall 2 are provided.

  At least the side wall 3 is made of a multilayer material comprising a plurality of layers overlapping each other, at least one of the layers 30 being made of an opaque material (ie avoiding the passage of light) and at least one One layer 31 is made of a transparent material (i.e., allows light to pass through and allows the user to see the amount of food in the container 1). The multilayer material described above is a heat-seal plastic material such as paper, aluminum, and polyethylene.

  The bottom wall 2 and the top wall 4 are also preferably made of the same material as the side wall 3.

  The layer 30 of opaque material (e.g. paper and / or aluminum) forming at least one side wall 3 of the container 1 is provided with a plurality of holes 5, 5 ', which are transparent materials (e.g. polyethylene). The layer 31 is closed.

  Specifically, the holes 5, 5 'are adjacent to each other along the longitudinal direction D and each has a peripheral edge 50, 50' that defines a closure profile. The maximum distance between the two points of the peripheral edge 50, 50 '(i.e. the distance between the two distal points) is 4-8 mm (see in particular Fig. 1A).

  Advantageously, according to technical tests, the maximum distance described above between the two points of the peripheral edge 50, 50 ′ of each hole 5, 5 ′ (ie the maximum width of each hole 5, 5 ′) It has been demonstrated that the inside of the container 1 can be properly visually recognized without adversely affecting the properties. Actually, the holes 5 and 5 'of this size do not weaken the strength of the container 1 and at the same time allow the food in the container 1 to be sufficiently visible.

  Obviously, considering the first hole 5 and the second hole 5 ′, the maximum distance between the two points of the peripheral edge 50, 50 ′ of the same hole can be different (ie, the two holes 5, 5 'can have different widths).

  The side walls 3, 3 of the container 1 are adjacent to and connected to each other via a first bend line 6, and the bottom wall 2 and the top wall 4 are each side walls via a second bend line 60. Connected to 3. In other words, the first fold line 6 and the second fold line 60 constitute an edge of the container 1.

  Specifically, the distance between each hole 5, 5 ′ and the proximal (ie, closer) first bend line 6 and / or the proximal second bend line 60 is the respective perimeter. This is proportional to the maximum distance between the two points 50 and 50 '.

  Such a proportional relationship has been calculated in order to avoid damage to the packaging material making the container 1 and is advantageous.

  The distance between each hole 5, 5 'and the proximal first bend line 6 and / or the proximal second bend line 60 is (peripheries 50, 50' of each hole 5, 5 '. 4 to 16.5 mm (depending on the maximum distance between the two points).

  For example, the distance between two adjacent holes 5, 5 'is 11 to 12.5 mm. Advantageously, if two adjacent holes 5, 5 'are required, such a distance is a minimum distance to ensure the integrity of the container 1.

  In the attached figures, the peripheries 50, 50 'of the holes 5, 5' are circular. Therefore, in this case, the maximum distance between the two points of the peripheral edge portions 50 and 50 'corresponds to the diameter of the circular edge portion.

  Obviously, the perimeter can have a non-circular contour (eg square, triangular or rectangular). In FIG. 6, the holes are oval or elliptical.

  Still referring to the figure, the holes 5, 5 'are arranged along a curved path that develops along the longitudinal direction D described above.

  Advantageously, the invention described in this specification makes it possible, on the one hand, to have visibility along the overall development in the longitudinal direction of the container 1, which on the other hand is optimal for the container 1. Be able to provide aesthetic aspects.

  The holes 5, 5 'are preferably arranged along two adjacent parallel rows. Such an aspect not only contributes to providing an optimal aesthetic aspect for the container 1, but also provides high visibility to the interior of the container 1.

  Alternatively, there can be more than one or two rows of holes, i.e., 3, 4, 5, etc. These rows can be longitudinal or transverse with respect to the deployment axis H.

  For example, when there are two or more rows of holes, the distance between two holes 5, 5 'in adjacent rows can be set to 11 to 12.5 mm.

  For example, the number of holes 5, 5 'may be different for each row (seen in the longitudinal or transverse direction with respect to the deployment axis H (see FIG. 5)).

  According to a variant not shown, the container 1 can further comprise at least one symbol arranged along the longitudinal direction next to the hole and representing the amount of food in the container 1.

  This is advantageous because the user can know the corresponding amount by checking the level of the contents in the container 1. This code is, for example, a notch displaying a corresponding amount of value.

  Alternatively, the same result is obtained in the direction transverse to the deployment axis H of the container 1, where each row comprises holes 5, 5 ′ with a different number of holes in proportion to the amount of food in the container 1 at that level. (See FIG. 5).

  According to the alternative shown in FIG. 6, the width of the holes 5, 5 ′ is proportional to the amount of food in the container 1. In other words, the holes 5, 5 ′ closer to the bottom wall 2 are narrower than the holes 5, 5 ′ closer to the top wall 4.

  According to a preferred embodiment shown in FIGS. 2 and 3, the container 1 comprises at least one cover strip 7 made of an opaque material and removably attached to the surface of the holes 5, 5 ′. I have. Advantageously, the cover strip 7 can cover the holes 5, 5 ′ from light and can be removed only when the user needs to check the amount of the contents of the container 1.

  For example, an adhesive that can be easily attached and detached is used for the cover strip 7.

  The cover strip 7 is preferably made of aluminum. By being made of aluminum, it is advantageous because it can reflect light rays.

  FIG. 2 shows the container 1 with cover strips 7 attached to the holes 5, 5 '.

  FIG. 3 shows the same container 1 as in FIG. 2, but the cover strip 7 has been partially removed from the holes 5, 5 '(ie from the side wall 3).

  Referring to FIGS. 5 and 6, the container 1 has at least the auxiliary hole 11 (2 in the figure so that a sufficient amount of light for optimizing the visibility inside the container 1 can be entered for the user. Two auxiliary holes 11).

  For example, the auxiliary hole 11 is provided in the top wall 4 of the container 1. In this case, obviously, the top wall 4 is also made of a multilayer material consisting of a plurality of layers in which at least one layer 30 of opaque material and at least one layer 31 of transparent material are superimposed on each other. As a result, the auxiliary hole 11 is formed of only the opaque material layer 30 and is closed by the transparent material layer 31.

  For example, each auxiliary hole 11 is oval or elliptical as in the case of FIGS. Alternatively, each auxiliary hole 11 can have any other shape suitable for putting sufficient light into the container 1 in order to improve the visibility of the food in the container 1.

  FIG. 4 shows a sheet 8 (for example an assembly element or a punching element) from which the container 1 can be made. As is clear from FIG. 4, the holes 5, 5 ′ are provided in the seat panel constituting the side wall 3 of the container 1 and are closed with a transparent material.

  In FIG. 4, the first bend line 6 and the second bend line 60 that constitute the edge of the container 1 can also be seen.

  Furthermore, in FIG. 4, the opening 9 can be seen. The opening 9 is provided to provide the container 1 with a cap 10 used as a dispensing device (the cap 10 can be seen in FIGS. 1 to 3 and FIGS. 5 to 6).

  FIG. 7 shows a sheet 80 that is similar to the sheet 8 of FIG. In the sheet 80, the two auxiliary holes 11 and the above-mentioned cover strip 7 can be seen. Furthermore, in the sheet | seat of FIG. 7, the 1st bending line 6 has a curved outline instead of a linear outline.

  In this way, the sheets 8, 80 from which the container 1 can be obtained are single sheets 8, 80 which are bent, filled and closed as described above, or a laminate which is unwound from a reel, for example. It can be a continuous strip of material (not shown). Obviously, in the latter case, several containers 1 can be obtained from the continuous strip by pre-arranging the appropriate bending lines described above in order. In this case, the continuous strip is continuously fed to a machine for producing and filling injectable food containers.

  The container 1 and the sheets 8 and 80 proposed in the present invention can always monitor the amount of food in the container 1, and at the same time both damage to the container 1 itself and the incidence of excessive light on the container 1 itself. Can be avoided.
