FRAME ELEMENT FOR PACKAGING FLAT ITEMS AND WRAPPER MADE FROM SUCH ELEMENTS

The present invention relates to a frame member for packaging a flat article and a packaging connecting these members.

More particularly, the present invention relates to a member configuration for forming an entirety or a part of a frame that protects the flat article or products when storing or transporting substantially flat articles or products, or in all cases.

Flat articles are associated with products that are particularly small compared to areas with different thicknesses of the product. Such articles may generally have parallel hexagonal, cylindrical, polygonal or other complex shapes.

Such frame members are particularly useful in the field of logistics for the transport and packaging of flat and fragile products or devices such as flat screen televisions, glass panels, drawings and the like.

In general, large flat items are packaged in containers such as wooden or cardboard boxes, which are secured through shims to selectively join other packaging members to collect honeycomb materials (polystyrene), fiber particles (grains or beads). Protected from shocks.

However, such protection means has a cost problem because the bulk of the other members and other materials are used to move and sequential processing to the packaging place, and it takes up a large amount of space after recycling after use.

It is an object of the present invention to solve these technical problems in a satisfactory manner, which proposes a solution which can effectively cover and view the thickness of such articles in a small volume.

This object can be achieved according to the invention using a frame member for packaging a flat article, which frame member comprises one or more first and second shapes connected in a single piece in the longitudinal direction via a flexible hinge. Each of the shapes includes a lateral groove that is laterally defined in an arrangement of two notches to receive the article, each notch of the first and second shapes around the hinge having the first and second shapes; A contact stop is formed to block the two shapes at a relative angular position where respective grooves of the shapes open opposite the edge of the article to be protected.

According to an advantageous feature of the invention, the notches are constructed and positioned such that two identical members engage the first and second shapes with one another and overlap in reverse and head-to-tail.

According to another feature, the notches of one of the first shaped arrangements are made of a straight wall and an internal protrusion extending outwardly by a crossing shoulder.

According to another advantageous variant, the notches of one of the second shaped arrangements are separated by an outer flat portion extending into the undercut.

According to another variant, a shock absorbing cell is formed in the notches of one of the first shaped arrangements.

Preferably, the second shape has a single longitudinal space at the bottom for absorbing the impact.

According to one particular embodiment, the frame member comprises two or more associated shapes.

According to one particular variant, stops are formed on both sides of the hinge with inclined surfaces extending inwardly of the first and second shapes.

According to another variant, the frame member according to the invention comprises means for fixing the contact stop.

Such fastening members preferably consist of protrusions supported through the second shape, the surfaces being rotated inwardly of the first shape being supported by shoulders transversely outside the notches next to the corresponding protrusions received in opposing undercuts. .

According to another particular embodiment, the notches are made in the form of triangular saw teeth.

According to another variant, which is configured to be useful for storing and transporting the frame members, the flexible hinge is configured to be able to fold the two shapes 180 °, at least behind one another.

In this case, the inner shapes of the two shapes are mutually adapted to engage or press with each other after folding back 180 °.

Another object of the invention is a packaging material made of one or more of the frame members described above for packaging flat articles.

The frame member according to the invention enables ergonomic and cost effective packaging of fragile products in flat form that is difficult and vulnerable to handling and transport to manufacturers, transporters, users and consumers.

The frame member according to the invention has a simple structure, is formed of a single piece of prop, and is easy to industrially manufacture and apply.

Such frame members may be used in conjunction with a container that is mounted at the outer circumferential edge of the article, or optionally forms a sealed and sealed outer perimeter, depending on the nature of the article to be packaged.

The structure of such a member is a self-supporting structure that is removably secured to the thickness of the article and is adjusted to different sizes and types of flat articles without significant deformation.

Apart from being able to fit and support the article, it is possible to significantly reduce or absorb any impact through dedicated means, supported by the frame itself, and to preserve the packaged article against any damage. The protection that can be obtained is remarkable.

In particular, it is a monolithic prop and can be easily reused many times, resulting in significant material savings.

Finally, many of the same members can be interlocked to make it compact, which is particularly cost effective even during storage.

The invention can be easily understood through the following detailed description and the accompanying drawings.

The frame members described in the figures are usually formed of a monolithic elongated prop comprising one or more first shapes 1 and one or more second shapes 2 having the same width, which are flexible hinges 3. It is assumed to be connected longitudinally through.

Each shape 1, 2 comprises an axial groove 10, 20 on which, like a rim, the outer peripheral edge of the flat article P described in FIG. 4 is mounted.

The frame member is preferably made of a deformable honeycomb material (foamed polystyrene type), through which it is possible to force the edges of the flat article to engage in the grooves 10, 20, and to provide a good mechanical fit of the assembly. Strength can be guaranteed.

The relative elasticity of the material can enhance the grip in the groove and the pressing force of the shapes 1 and 2 against the outer circumferential surface of the object P.

This groove is constrained transversely in each shape through sides made up of two parallel notches 11, 12, 21, 22.

In the embodiment described in FIGS. 1 and 2, the notches are substantially triangular in tooth shape.

However, the present invention does not limit the shape of other forms of such notches as long as it can overlap several members under the conditions disclosed below.

Thus, according to another embodiment not described, one or more of the first and second shapes may have a curved portion to mount the member to all or part of an article whose edge is not straight.

Each notch 12a, 22a of the two shapes 1, 2 adjacent to the hinge 3 is provided with a contact stop connected to the fixing members, which will be described later.

These stops hold the two shapes in such a way that the two shapes extend perpendicular to each other, forming a corner part, as described in FIG. 2.

However, these stops may be secured in an angled arrangement other than 90 ° to suit the particular contour and shape of the flat article to be packaged.

In the case of using the member according to the present invention, the grooves 10 and 20 of each shape 1 and 2 are connected to accommodate the corners and corners of the flat article P, such as a frame, and fasteners facing the inner cabinet. As open, they face each other.

When the hinges 3 are closed, as shown in FIG. 4, they are located at the corners of the flat article.

More generally, it is possible to fasten the frame member according to the invention to the straight edges of the flat article P without folding the hinge 3 as an edge, and to fix the two shapes in corresponding positions respectively. no need.

The flexible hinge 3 is of a type known per se, made of thin regions as part material of the member, and preferably located in the center between the first and second shapes 1, 2. Through this hinge, the two shapes can be elastically folded to each other.

The notches 11, 12, 21, 22 are two identical in the reverse and head-to-tail manner by bending the first and second shapes from each other, as shown in FIGS. 3A and 3B. The member is constructed and positioned so that it can overlap.

The notch 12 of one of the two arrangements of the first shape 1 is made of a straight wall and an internal protrusion 121 extending outwardly by a crossing shoulder 122 (FIGS. 1, 2, 5A and 5B), one of the two arrangements of the second shape 2, notches 22 are separated by an outer flat portion 222 extending into the undercut 221.

The other notches 11, 21 of the two shapes 1, 2 are the same as shown in FIG. 2.

The shape of the undercut 221 of the second shape 2 is, as shown in FIGS. 3A and 3B, the protrusions of the notches 12 of the first shape 1 facing each other when the two members are stacked. 121). At the end, as shown in FIG. 2, the protrusion 121 and the undercut 221 form a first side of the member.

In addition, the show rater 122 of the first shape 1 bears on the flat portion 222 of the second shape 2. This first nesting is very small and can significantly reduce space.

Another method for optimally storing the frame member will be described below.

On both sides of the hinge 3, stops are formed with inclined surfaces 13 and 23 extending inwardly of the first and second shapes, respectively. As shown in FIG. 2, these inclined surfaces are configured to support each other when closing the hinge.

More specifically, in the illustrated embodiment, as shown in FIG. 1, the groove 20 of the second shape 2 is located at a height higher than the groove 10 of the first shape 1. do. In this arrangement, the inclined surface 13 of the notches 11, 12a of the first shape 1 is in contact with the inclined surface 23 of the second shape 2 having a larger surface area.

The fixing members consist of protrusions supported through the notches 22a of the second shape 2, and as shown in FIG. 2, the surface 23a which is rotated into the first shape 1 is The corresponding protrusion 121 is received by the opposite undercut 221 and is supported by the crossing shoulder 122a on the outside of the notch 12a next to it.

One notch of the one or more arrangements of the shape 1 (notch 12 here) is formed with a lower cell 14 which absorbs the impact.

In the second shape 2, one longitudinal space 24 for absorbing the impact is formed at the bottom.

In the illustrated embodiment, in particular in the case of FIG. 2, the cell 14 and the space 24 are formed on the same side of the two shapes 1, 2, and can be positioned to face each other if necessary. . Thus, the cell 14 and the space 24 form an empty space region to absorb kinetic energy that can be delivered directly to the body upon impact (fall, collision, etc.), thereby preserving the integrity of the article. Can be.

If desired, the longitudinal space 24 may be used as an ergonomic space that can accommodate the accessories of the article to be packaged.

According to another variant, not shown, the member comprises more than two shapes. At this time, the first and second shapes are connected to each other like a chain of bicycles and cover the circumference of the article P very close by grounding the article P.

As shown in FIG. 4, the second shape 2 can be mounted to the bottom of the flat article P, forming a base when formed. At this time, the short wall of the longitudinal space 24 may advantageously be arranged in an arch shape and, if possible, reinforced to ensure stability.

In the variant shown in FIGS. 7A and 7B, the first and second shapes 1, 2 are shown in simple form. In this variant, in particular, the flexible hinge 3 is deformed and configured to be elastically folded in both directions.

The fold of the two shapes facing each other in the closing direction has already been described. 7A and 7B show the folding of the two shapes folded back 180 ° to each other (open direction indicated by arrows in FIG. 7A). As mentioned above, an angle of 180 ° is not necessary to close the fold, and this purpose is to protect the corners of the flat article.

However, in this other variant, the fold may be configured to be useful for packaging and conveying the frame member itself. Indeed, in order to reduce the volume of the frame member during storage and transport, ie delivery to the place of use, it is advantageous to fold the two shapes behind one another, as in FIG. 7B.

In this case, when the outer surface or the rear surface 15, 25 of the two shapes 1, 2 are flat (described in Figs. 7A, 7B) or folded back 180 °, their shapes are mutually bent or mutually folded back. May be pressurized.
