Abstract
Description
[0001] “Protective packaging”
[0002] DESCRIPTION
[0003] The present invention refers to a protective packaging. The present invention preferably refers to a protective packaging suitable for protecting an article during shipping or transportation, thereof.
[0004] Protective packagings are often used to protect the articles contained therein from collisions and impacts during shipping or transportation. When relatively fragile or precious articles are to be transported or shipped, it is often provided that the article is contained inside the packaging in a cushioned manner to protect it from a physical impact that might be caused by collisions suffered by the packaging during shipping or transportation.
[0005] In most cases, an additional structure placed between the article and the outer walls of the packaging is used to house the article inside the packaging in a cushioned manner. Such additional structures include, for example, crumpled paper, air-filled plastic cushions, moulded foam, or accordion-folded pieces of cardboard.
[0006] The Applicant thinks that the packagings, including protective packagings, should seek to increase, or at least not decrease, the perceived value of the articles contained therein.
[0007] Without wishing to prove any theory, in the Applicant's experience the perceived value can be seen as an overall evaluation of the usefulness of an article, based on the perception of the relationship between price and quality.
[0008] In the Applicant's experience, the unboxing experience (i.e. the action of removing an article from the packaging for the first time) also contributes to the perception of the relationship between price and quality. In particular, a fulfilling unboxing experience (consciously or unconsciously) can increase the perceived steam of an article, while a disappointing unboxing experience can decrease the perceived value of an article.
[0009] In the Applicant's experience, a fulfilling unboxing experience should provide for ease of access to the article and avoid possible damage to the article during removal thereof from the packaging. The Applicant has in fact noted that having to remove the various additional structures from the protective packaging and having to stack them or in any case temporarily store them in order to be able to access the article, as well as having to take special care not to damage the article while the additional structures are being removed, may result in an unfulfilling unboxing experience and therefore decrease the perceived value of the article itself.
[0010] Moreover, a packaging that presents itself with attention to detail even when opened, can make the unboxing experience fulfilling.
[0011] In fact, in the Applicant's experience, an unboxing experience in which the packaging does not have appendages, flaps, visible interlocks, visible joints and the like, can generate a feeling of care and attention in the packaging that can make the unboxing experience rewarding.
[0012] On the contrary, the Applicant thinks that an unboxing experience during which the packaging appears neglected in its detail by exposing appendages, flaps, interlocks, joints to view might give rise to a feeling of inadequacy of the packaging that could negatively impact the unboxing experience.
[0013] Furthermore, the Applicant thinks that the protection of the environment must be taken into extreme consideration also in relation to the manufacture of packagings, including the protective packagings.
[0014] The Applicant is of the opinion that the protective packaging has to be not only as recyclable as possible but should also be designed in such a way that it can be effectively recycled, especially for the protection of the environment and also because this can further increase the perceived value of the article. In this sense, the Applicant considers that an end user must be able to easily and quickly dispose of the protective packaging by separate collection (which constitutes the first step for an effective recycling process).
[0015] The Applicant has perceived that if anchoring structures, interlocks or the like were concealed from view by superimposing on these anchoring structures, interlocks preferably continuous walls that also have a function of containing the article and cushioning it during transport, the protective packaging would be able to adequately protect the article during transport and would appear neat during the unboxing experience. The Applicant has also perceived that by manufacturing such a protective packaging entirely of paper material, the end user would not be obliged to disassemble all the parts of the packaging in order to be able to dispose of it by separate collection, making it possible to effectively recycle the protective packaging.
[0016] The Applicant has found that by using paper material to make a protective packaging which provides for a box that incorporates in two first opposite side structures cushioning structures consisting simply of walls extending between two second opposite side walls of the box and anchoring to the base wall of the box, and which also envisages a structure inserted internally to the box having further walls which create cushioning structures also for the second opposite side walls of the box and which has a back wall concealing from view the anchoring structures of the cushioning structures of the first two side walls of the box, it is possible to obtain a recyclable protective packaging that appears taken care of in the details even when opened to remove the transported article.
[0017] The present invention therefore concerns a protective packaging made of paper material.
[0018] Preferably, the protective packaging comprises a containment box and an inner structure.
[0019] Preferably, the containment box comprises a base wall, a back wall, a front wall, a first side structure and a second side structure.
[0020] Preferably, said first side structure and said second side structure respectively comprise an outer wall, an inner wall parallel to and spaced from said outer wall and extending from said front wall to said back wall.
[0021] Preferably, said first side structure and said second side structure respectively comprise an upper wall which connects and spaces out from each other said inner wall and said outer wall.
[0022] Preferably, said first side structure and said second side structure respectively comprise a lower wall connected to said inner wall on the opposite side with respect to said upper wall, parallel to said base wall and overlapping said base wall. Preferably, the inner structure comprises a first outer side wall and a first inner side wall parallel to said first outer side wall, wherein said first outer side wall is in contact with said back wall and wherein said first inner side wall extends from said inner wall of the first.
[0023] Preferably, the inner structure comprises a second outer side wall and a second inner side wall parallel to said second outer side wall, wherein said second outer side wall is in contact with said front wall and wherein said second inner side wall extends from said inner wall of the first side structure to said inner wall of said second side structure.

[0025] Preferably, said rest wall, said first inner side wall, said second inner side wall, said inner wall of the first side structure and said inner wall of said second side structure define a housing volume for an article.
[0026] The Applicant has verified that in this way the protective packaging has three walls substantially at each perimeter side and two substantially overlapping walls at the back.
[0027] The Applicant believes that this is able to adequately protect the article contained in the packaging volume from any collisions.
[0028] The Applicant has also verified that the inner structure and in particular the first inner side wall, the second inner side wall and the rest wall cover the lower walls of the first side structure and of the second side structure of the containment box from view, defining a housing volume free of unsightly tabs, appendages, flaps, interlocks or joints.
[0029] The expression “paper material” means a material based on paper or paper pulp in the form of single sheets or panels or sheets or panels overlapping on each other or interspersed with one or more corrugated sheets in which the ratio of weight to surface area (grammage) is between about 100 grams per square metre and about 650 grams per square metre. The expression “integral” when referred to two walls means that the two walls are made in one piece, that is, the two walls are made from a single continuous piece and without interruptions or cuts of paper material.
[0030] The expression “height” means a measurement along a direction perpendicular to the base wall of the containment box.
[0031] The expression “width” means a measurement along a direction parallel to the base wall of the containment box and perpendicular to the outer wall of the first side structure of the containment box.
[0032] The expression “length” means a measurement along a direction parallel to the base wall of the containment box and parallel to the outer wall of the first side structure of the containment box.
[0033] The expression “connected” when referred to two or more parts of the protective packaging, means that these two or more parts are joined together in a stable and permanent manner.
[0034] The expression “extends from a (first) wall to a (second) wall” when referred to a wall of the protective packaging, means that said wall at its own first end reaches and preferably comes into contact with the (first) wall and, at its own second end, reaches and preferably comes into contact with the (second) wall.
[0035] The expression “wave direction” means the direction followed by the ridges and by the depressions of the insert of corrugated paper inserted between a first and a second flat sheet in a so-called corrugated cardboard. Such ridges are usually glued to the first flat sheet of corrugated cardboard and such depressions are usually glued to the second flat sheet of corrugated cardboard.

[0143] The containment box 11 further comprises a seal wall 27. The seal wall 27 is integral only with the lid wall 22. The width of the seal wall 27 is equal to the width of the lid wall 22. The seal wall 27 is arranged parallel to the front wall 19 when the lid wall 22 is folded in closure of the containment box 11 . The seal wall 27 overlaps the front wall 19 on the side outside the containment box 11 when the lid wall 22 is folded to be closed. The seal wall height 27 is less than the height of the front wall 19. In the preferred form of the invention, the seal wall 27 is glued to the front wall 19 at least before the first opening of the packaging 10 takes place.
[0144] The seal wall 27 comprises a tear tab 28 (schematized in the accompanying figures) having a width equal to the width of the seal wall 27. The tear tab 28 can be made by two parallel lines of partial incision which are placed on the seal wall 27. The tear tab 28 is placed on the seal wall 27 in a position where no glue is present between the seal wall 27 and the front wall 19.
