Description

  The present invention relates to a frame member for packing a flat article and a packaging material obtained by joining the members.

  In particular, the invention relates to a member designed to form all or part of a frame that protects the article or product when the substantially flat article or product is stored and / or transported.

  A flat article refers to a product whose thickness dimension is particularly small compared to other dimensions.

  The article may have a generally parallelepiped, cylindrical, polygonal, or other complex shape.

  The frame member can be used particularly in the field of physical distribution for the purpose of packing and delivering flat and fragile products and equipment such as flat screen televisions, glass panels, and paintings.

  In general, a large flat article is packed in a container such as a wooden box or a cardboard box, and the article is fixed with a shim in the container, and particles (pellets or beads) or fibers of honeycomb material (polystyrene) are collected. Protected from impact, optionally in combination with other packaging members.

  However, these safeguards mean that a considerable amount of different parts and different materials are used, both in terms of bulk problems, recycling problems, and therefore in both transport to their packaging and management after use. Cause cost problems.

  The present invention solves the above technical problem in a satisfactory manner by proposing a solution that enables efficient and compact covering and protection of thick parts of such flat articles. Objective.

  This object is achieved by the present invention using a frame member for packing flat articles. The frame member includes at least one first profile portion and at least one second profile portion, and the first profile portion and the second profile portion are formed on a single same piece and are elongated by a flexible hinge. Each having an axial groove for receiving the article, connected in a direction and delimited on both lateral sides by two notch rows. The notch teeth corresponding to the profile portion adjacent to the hinge have the relative angular position at which the corresponding groove of the profile portion opens so as to face the end portion of the article to be protected. A contact stop for reliably positioning the two profile portions is provided.

  According to one advantageous configuration of the invention, the notch teeth are head-to-tail compatible in the reverse direction by connecting the first profile part and the second profile part. Configured and positioned to overlap in form.

  According to another advantageous configuration of the invention, one notch row of the two notch rows of the first profile part is a straight wall extending laterally outwards by a lateral shoulder. Consists of inner projections with

  According to another alternative form of the invention, a plurality of lower buffer chambers are provided in at least one of the notched teeth of the first profile portion.

  Preferably, the second profile portion is provided with one longitudinal lower cavity for buffering.

  According to one embodiment of the present invention, the frame member includes two or more connected profile portions.

  According to one specific alternative form of the present invention, the contact stop is inclined on both sides of the hinge and extending from the adjacent inner ends of the first profile part and the second profile part. Formed by.

  According to another alternative, the frame member according to the invention includes means for locking the contact stop.

  The means for locking is preferably constituted by a projecting portion supported by the second profile portion, and a surface of the second profile portion (2) facing the first profile portion is the nearest adjacent cut portion. The corresponding protrusion on the inner side in the lateral direction of the shoulder portion is accommodated in the counterbored portion of the opposing second profile portion (2) while abutting on the outer lateral shoulder portion of the chipped tooth.

  According to yet another particular embodiment of the invention, the notch teeth are made in the form of a triangular tooth.

  According to yet another alternative of the present invention, designed to facilitate storage and transport of the frame member, the flexible hinge is 180 ° relative to each other at least towards the back. Designed to be bent at an angle.

  In that case, the shapes of the inner surfaces of the two profile parts are complementary so that the profile parts can be connected or pressed together after being bent 180 ° toward the back surface.

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

  The frame member according to the present invention is difficult to handle and deliver for manufacturers, transporters, users and consumers due to its flat shape and fragility, and it is ergonomic for products that use nerves. Enables the provision of cost effective packaging based on

  The frame member according to the present invention has a simple structure of integral molding, and manufacture and arrangement of the frame member are industrially easy.

  In particular, since the frame member is integrally formed and can be easily reused many times, material can be saved greatly. Finally, in the storage of the frame member, a plurality of identical members can be connected in a compact manner, so that particularly high cost efficiency can be obtained.

  The invention will be better understood upon reading the following description in conjunction with the drawings.

It is the perspective view shown in the position which expanded one Embodiment of the frame member of this invention. It is the perspective view shown in the position which bent the frame member of FIG. It is the perspective view which showed the state before stacking two frame members which concern on embodiment of FIG. 1 and FIG. It is the perspective view which showed the state after stacking of FIG. 3A. It is a perspective view of the flat article | item packed using the frame member which concerns on embodiment of FIG. 1 and FIG. (A) And (b) is respectively a top view of the 1st profile part of the frame member concerning the present invention, and a transverse cross section along an AA line of (a). (A) And (b) is respectively a top view of the 2nd profile part of the frame member which concerns on this invention, and a cross-sectional view along the BB line of (a). It is the schematic perspective view which showed alternative embodiment of the frame member of this invention. It is a schematic perspective view which shows the state which the frame member of FIG. 7A bent.

  The frame member shown in the figure includes, in a free state, a single member including at least one first profile portion 1 and one second profile portion 2 that are connected by a flexible hinge 3 in the longitudinal direction and have the same width. Take the shape of a strip.

  Each of the profile parts 1 and 2 includes longitudinal grooves 10 and 20 extending in the longitudinal direction, and the grooves accommodate the peripheral edge of a flat article P (shown in FIG. 4) like a flat edge.

  The frame member is preferably made of a deformable honeycomb material (of a polystyrene foam type), which forces the end of a flat article to fit into the grooves 10 and 20 and pushes it away from the frame member and the part. Good mechanical strength of the assembly can be ensured.

  The grip of the groove and the pressing of the profile parts 1 and 2 against the flat surface around the article P may be strengthened by the relative elasticity of the material of the frame member with respect to the part P.

  This groove has two rows of V-shaped notches (notch) 11, 12, 21, 22 in parallel in the lateral direction on each profile part, and the boundary on both sides in the lateral direction (flank). Is stipulated. In the embodiment shown in FIGS. 1 and 2, the notch teeth are made in the shape of a substantially triangular tooth.

  However, the present invention does not exclude different shapes of these notched teeth as long as a plurality of members can be overlapped by the notched teeth under the conditions presented below.

  Similarly, according to an alternative not shown, at least one profile portion may be bent in order to attach the member to all or part of an article whose end is non-linear.

  Each of the notched teeth 12a and 22a of the two profile portions 1 and 2 adjacent to the hinge 3 is provided with a contact stop portion that is coupled to a locking member described later.

  As shown in FIG. 2, these contact stoppers form a corner locally, and lock the two profile portions by engaging with each other at a position extending perpendicularly at 90 °.

  However, it is possible to fit these contact stops in an angular direction other than 90 ° by fitting to the specific contour and profile of the flat article to be packed.

  In this position consistent with the use of the member according to the invention, the corresponding grooves 10, 20 of the profile parts 1, 2 are in the shape of jaws to receive the corners and ends of the flat article P like a frame. , Opening toward the inside of the angle and facing each other.

  The hinge 3 is closed and positioned at the corner of a flat article as shown in FIG. More generally, the frame member according to the present invention can be attached like an edge member along the straight end of the flat article P without bending the hinge 3, and the two profile portions. Need not be locked in their respective positions.

  The flexible hinge 3 is of a known type per se, and is preferably formed of a thin region of the constituent material of the frame member and is located at an intermediate position between the profile portions 1 and 2. This hinge makes it possible to elastically bend the two profile parts with respect to each other.

  The notch teeth 11, 12, 21, and 22 are configured and positioned as shown in FIGS. 3A and 3B, and the first profile portion and the second profile portion are engaged with each other and connected by snapping. Both profile portions are reversed and can be superimposed by a head-to-tail facing method.

  One notch tooth row 12 of the two rows of notch tooth rows of the first profile portion 1 is constituted by an inner protrusion 121. Each projection 122 is accompanied by a straight wall extending laterally outward by the shoulder 122 (FIGS. 1, 2, 5 (a) and 5 (b)). On the other hand, one notch tooth row 22 of the notch tooth row of the second profile portion 2 is separated by an outer flat portion 222 extending inward so as to enter the inside of the first profile portion 1 by the bore portion 221. It is done. As shown in FIG. 2, the notched teeth 11 and 21 of the other notched tooth row of the two profile parts 1 and 2 are the same.

  As shown in FIGS. 3A and 3B, the shape of the counterbored portion 221 of the second profile portion 2 faces the first profile portion 1 when the two members are stacked, and engages with the protrusion 121 of the notched tooth row 12. The protrusion is received by being snapped. For this purpose, the protrusion 121 and the punched portion 221 are formed on the first side portion of the member as shown in FIG.

  In addition, the shoulder 122 of the first profile portion 1 abuts on the flat portion 222 of the second profile portion 2. This first stacking method is very compact and can significantly reduce the bulk.

  Another optimum storage method for the frame member will be described below.

  The said stop part is formed of the inclined surfaces 13 and 23 extended in the inner edge which mutually adjoins the 1st profile part 1 and the 2nd profile part 2 on the both sides of the hinge 3, respectively. The inclined surfaces are designed to abut each other when the hinge is closed, as shown in FIG.

  More specifically, in the illustrated embodiment, the groove 20 of the second profile portion 2 is positioned higher than the groove 10 of the first profile portion 1 as shown in FIG. In this configuration, the inclined surface 13 of the notched teeth 11 and 12a of the first profile portion 1 is in contact with the inclined surface 23 of the second profile portion 2 having a larger surface than the inclined surface.

  Here, as shown in FIG. 2, the locking member is constituted by a protruding portion supported by a notch tooth 22 a (FIG. 1) of the second profile portion 2, and faces the first profile portion 1 of the protruding portion. The face 23a that is in contact with the laterally outer shoulder 122a of the nearest adjacent notch tooth 12a, while the corresponding protrusion 121 is housed in the counterbored portion 221 on the opposite side.

  In at least one notch tooth row (in this case, the notch tooth group 12) of the notch tooth row of the profile portion 1, a plurality of lower chambers 14 for reliably buffering are provided below each notch tooth 12a. It is provided one by one. The second profile part 2 is provided with one longitudinal lower cavity 24 for buffering.

  In the embodiment shown in the figure, in particular in FIG. 2, the chamber 14 and the cavity 24 are made on the same side of the two profile parts 1, 2 but, if necessary, the chamber and the cavity are provided on both sides. It is also possible. Thus, the chamber 14 and the cavity 24 form a cavity region for absorbing kinetic energy that may be incidentally transmitted to the package upon impact (falling, shaking, etc.). Keep it intact.

  If desired, the longitudinal cavity 24 may serve as a storage chamber based on ergonomics, thereby allowing an accessory to be packaged to be received.

  According to an alternative not shown, the member comprises two or more profile parts. In this case, the profile parts are connected to each other like a bicycle chain, and by covering the article P, the periphery of the article is completely covered without any gap.

  As shown in FIG. 4, the second profile part 2 can be attached to the lower part of the flat article P, and as a result, provides a base for the package to be formed.

  To that end, the end walls of the longitudinal cavity 24 are preferably arranged in an arch shape and, where possible, reinforced to ensure better stability.

  In the alternative illustrated in FIGS. 7A and 7B, the profile parts 1 and 2 are simplified. In this alternative, the flexible hinge 3 is set in particular so that it can be bent elastically in both directions.

  It has already been described that the two profile parts are folded together in the closing direction. 7A and 7B illustrate folding the two profile parts 180 ° toward each other toward the back (opening direction indicated by the arrow in FIG. 7A). An angle of 180 °, as already described, was not essential to complete the folding and its purpose was to protect the corners of flat articles.

  However, in this alternative, the folding is specifically designed to allow and facilitate the packaging and transport of the frame member itself. Actually, in order to reduce the bulk of the frame member for storage, transportation, and delivery to the place of use, it is advantageous to fold the two profile portions back to back as shown in FIG. 7B. is there.

  In this case, the outer surfaces of the two profile parts 1 and 2, that is, the back surfaces 15 and 25 are flat (FIGS. 7A and 7B). Alternatively, the shape of the profile portion may be a complementary shape that snaps together after the profile portion is bent 180 ° toward the back surface, or fits together so that the back surfaces can be pressed against each other. To do.
