Description

Lower or upper part of an octavín, and a structure folded in plane thereof

The invention relates to a lower or upper part of an octavin, and a flat folded structure thereof.

In the field of packaging, octavines are known, which are usually made from cardboard or corrugated cardboard. The dimensions of the octavines are such that an octavín occupies a pallet, which makes the octavín useful for transport. In the context of the invention, octavines are conceived that consist of a tubular piece of vertical walls, the ends of the tubular piece being covered by a lower piece and an upper piece that join with the tubular piece. For positioning the lower part or the upper part (also called, hereinafter, capping piece) in connection with the tubular part, the capping piece has an end plate with vertical parts that are more or less perpendicular to the end plate. The vertical parts or side panels fit tightly inside the walls of the tubular part or vice versa.

There is a general need to provide octavines that are easy to assemble before use, and that at the same time are easy to transport when not in use. For example, the tubular piece folds easily to form a flat structure, which easily conforms to form a tubular structure. To this day, the capping piece is made of independent pieces (flat and easy to transport), which therefore must be interwoven or glued together before use. An alternative is known which consists of an eight-corner endplate that has side panels, in which adjacent side panels are glued to each other above a connection flap. The side panels can be folded inwardly so that a zigzag part is formed between adjacent panels. Such a flat-folded lid piece has the advantage that it can be easily deployed to form a structure for use to cover a tubular piece, but it has some disadvantages. First, the flat folding of the capping piece is not perfectly flat: the zigzagging parts have a tendency to unfold automatically. In this way, a stack of stored capping pieces are prone to move and not form a stable stack. Secondly, in the deployed configuration the cover piece has a tendency to fold again to form a closed, flat folded configuration. This makes positioning for joining with a tubular piece less easy, or more cumbersome. In addition, a less stable configuration of a capping piece could jeopardize operation as a cover for the octavin.

Document DE 20 2004 005 667 U1 explains a preform to be erected inside an octavin, the preform comprising alternating male and female parts to be folded so that they engage with each other.

Therefore, there is a need for a capping piece that has a stable configuration when folded flat (for transport), as well as when deployed (for use as a cover for an octagon).

With that aim, the invention provides a flat folded structure of a lower or upper part of an octavin, which can be easily deployed to a stable upright position, comprising:

an end plate of eight corners delimited by eight lateral lines, in which on each lateral line a folding lateral panel is fixed, each lateral panel being able to be folded by the respective lateral line.

the side panels being alternating male and female panels, where a male panel comprises a main part that has two flaps on its side sides, where each flap can be folded by a folding line that separates the flap from the main part, and where a female panel consists of an inner part contiguous to the lateral line, and an outer part contiguous to the interior, the two parts of a female panel being separated by an envelope folding line for the double folding of the two parts a on the other to form an envelope structure, where the flat folded structure has the additional requirements:

the female panels and the male panels are folded by double folding inwards by the respective lateral lines in a sequential order of first folding the female panels and then the male panels, such that the flaps of the male panels are superimposed on top of the female panels, and then the female panels are folded by double folding outwards by the line for folding in the form of an envelope such that the outer parts overlap on the flaps of the male panels,

where each female panel has its outer part in a fixed position oriented towards the inner part by a durable fixation between both parts, in which each female panel forms an envelope structure between which the proximal side flaps of a male panel are secured with The movement allowed.

The fact that a cover piece is provided with side panels comprising an envelope structure permanently fixed to an inner part and an outer part between which a flap of a nearby panel is inserted and secured with the movement allowed, allows a flat folded configuration that is stable, and an unfolded configuration that is stable - that is, a stable perpendicular position of the panels relative to the end plate. In addition, the capping piece can be easily deployed by a user until he adopts an upright configuration for use.

Advantageously, the flaps of a male panel have a basically triangular shape. The triangular shape allows an appropriate freedom of movement inside the envelope structure.

In the invention it is preferable that the outer part of the female panel has a tongue with a fold line of the tongue, for a durable fixation with the respective inner part. The tongue achieves a fixation by means of a mechanical interlocking form with the inner part, or preferably by sticking the tongue to the inner part. Alternatively, the outer part can be glued directly on the inner part without a tongue being provided, or without the use thereof.

In a further preferred variant of the invention, the flaps of a male panel have a cam portion that protrudes on its upper face. The protruding cam part has the function of gripping into the envelope structure once the deployed configuration is complete - thereby contributing further to the stability of the configuration.

In another preferred variant of the invention, the female panels are provided with grooves near the line for folding in the form of an envelope or in said line. The grooves act as a housing means for parts of the flaps when the structure is in an open folded configuration, especially for cam parts of the flaps.

In a following preferred variant of the invention, the main part of the male panel and the outer part of the female panel have a rectangular shape. When placed in the unfolded configuration, these rectangular parts clearly form a closed ring of panels, which contributes to the function of the lower or upper part to ensure a capping of the tubular package as a lid.

In the invention it is further preferable that the inner part of the female panel has a rectangular shape, or has an hourglass shape with a partially reduced width. The freedom of movement for a flap within the envelope structure is influenced by the shape of the inner panel, along which a flap slides. Depending on the specific material, sufficient space is achieved by the specific shape of the inner part as defined.

In another aspect, the invention relates to a lower or upper part of an octavin, which is in an unfolded configuration of the plane folded structure according to one of the preceding claims, in which the side panels are placed in a perpendicular orientation with respect to the end plate of eight corners. The lower or upper part itself has all the advantages indicated above of a stable and durable positioning of the side panels with respect to the end plate, which makes it advantageous for use as a cover for an octavine tubular part. Finally, the cover piece can be folded back to the flat-folded configuration, for example for storage after it has been used as a cover.

Preferably, in the lower or upper part of the invention, the flaps of a male panel have a cam part protruding on its upper face, and the female panels are provided with grooves near the line for folding in the form of an envelope or in said line, and in the deployed configuration, the cam part is brought to an interconnection position with the corresponding slot. Said interconnection between panels also guarantees their stable positioning with respect to each other and with respect to the final plate.

The invention will be explained in greater detail by means of the attached figures, in which:

Figure 7 shows a detail of Figure 6.

Figure 1 shows a preform 1, comprising an end plate 3 of eight corners, delimited by eight lateral lines 5, in which on each lateral line a folding side panel 7, 9 is fixed, each side panel 7, 9 being foldable. along the respective lateral line 5, the side panels being male panels 7 and alternating female panels 9, where a male panel 7 comprises a main part 11 having two flaps 13 on its lateral sides, where each flap 13 can be folded by a line 15 folding that separates the flap from the main part,

and in which a female panel 9 consists of an inner part 21 adjacent to the lateral line 5, and an outer part 23 contiguous to the inner part 21, the two parts 21, 23 of a female panel being separated by a line 25 for Envelope folding for double folding of the two parts 21, 23 over each other to form an envelope structure. The outer part 23 of each female panel 9 also has a tongue 30 with a fold line 32 of the tongue, for a durable fixation with the respective inner part 21.

Figure 2 shows the preform 1 of Figure 1, in which the female side panels 9 are folded by double folding inwards by the respective side lines 5. Each triangular flap 13 has an extension 14 on its upper face, which acts as a cam. Each line 25 for folding in the form of an envelope is provided with two slots 26.

Figure 3 shows the structure of Figure 2, in which the male side panels 7 are folded in double fold inwards by the respective side lines 5, such that the flaps 13 of the male panels 7 are superimposed on top of the 9 female panels. In addition, a line of glue 35 is applied on the uncovered surface of the female panel 9 between the overlapping flaps 13.

Figure 4 shows the structure of Figure 3, in which the outer parts 23 are folded outwardly by the line 25 for folding in an envelope such that the outer parts 23 overlap on the flaps 13 of the male panels, and in which the tongue 30 is folded inwards by the fold line 32, contacting said tongue with the glue line 35, and with the uncovered surface of the inner part 21 between the overlapping flaps 13 .

Figure 5 shows the final phase of the structure 50 folded in plane after the completion of the last folding and fixing step of Figure 4. In this figure, each female panel 9 has its outer part 23 in a permanently fixed position with respect to the inner part by means of a durable fixation between both parts by the glue line 35, in which each female panel forms an envelope structure between which lateral flaps 13 close to a male panel 10 are secured with the allowed movement.

Figure 6 shows a lower or upper part of an octav 60, which is in an unfolded configuration in which the side panels 7, 9 have been placed in a perpendicular orientation with respect to the final plate 3 of eight corners. The configuration of figure 6 is obtained by simple unfolding of the plane-folded structure 50 of figure 5, until a perpendicular orientation of the panels is achieved, and does not require additional manipulation by a user. This orientation is stable due to the interlacing effect between the panels obtained by the mechanical connection between cams 14 which are placed within the grooves 26 of the envelope structure of the female panels 9.

Figure 7 shows a detail of the interlacing structure of a male panel 7 with a female panel 9, in which the cam 14 of a flap 13 protrudes through the groove 26 of the female panel 9, and engages behind a part of the female panel that forms the fold 25 of envelope. By pressing down each cam part 14, the user can unlock the interlocking structures and return the upper or lower cover to a flat folded configuration.
