Description

Cardboard box with folding fins.

Folded cardboard containers are known for package items, such as, for example, cardboard containers for Article distribution. Conventional cardboard packaging for the distribution of items can have a top panel with a distribution device formed therein. Sayings Cardboard containers can be used to contain items, such as beverage containers, for example, that can be distributed through the top panel or through another panel when the Cardboard container is open. Usually the containers Conventional cardboard should be refrigerated to keep cold the containers contained inside. When the containers of cardboard are no longer refrigerated, such as when a container of cardboard is taken out of the refrigerator to distribute the containers, The latter may become undesirably heated. By this, the containers must be refrigerated again or cooled by another mode. In addition, the distribution devices included in the conventional cartons can leave such containers without possibility of closing them again firmly once opened. By Therefore, items retained inside the carton they may fall involuntarily once it has been opened Said container.

Conventional cartons are usually formed from a single layer of cardboard or similar material. Transport handles can be formed in one or several panels of the cardboard container and can be used to take to it. Since cardboard containers are used usually for carrying relatively heavy items, such as beverage containers, the resistance of the handles or other sections of the carton packs must be increased to support the Carton container load. A conventional method to increase the load bearing capacity of a carton is to produce the same from an initial piece of a material different from cardboard, more resistant, or produce the starting piece from the same material of the cardboard container but with greater thickness or caliber. Such conventional methods usually increase costs associated with the manufacture of the carton, increasing from general mode material manufacturing costs in proportion to cost of increasing the strength and / or thickness of the entire piece initial. Some sections of the initial piece, however, may that do not support the load, and additional costs associated with increased resistance of sections of the starting piece that are not load bearing are wasted.

Document FR 2579175 A1 discloses a cardboard container particularly designed to contain meat fresh, whose cardboard container comprises two elements of the packaging of cardboard, namely an inner structure, of the cardboard container, of open top of tray type that receives the meat, whose inner structure of said container is housed in a structure outside, of the cardboard container, open top. Do not There is no union between the two elements mentioned. Rather, the extreme lateral wings of the outer structure of the packaging cardboard are inserted into folded cavities of the structure inside the cardboard container to keep the interior structure of said container.

The present invention aims to avoid the previously identified drawback of the packages conventional cardboard.

Detailed description

The first embodiment of the present invention generally refers to a cardboard container suitable for store and distribute items such as, for example, beverage containers The cardboard container provides a lower container suitable for accommodating, for example, liquids, ice, or other refrigerants in the bottom of said container. In one embodiment, by way of example, ice can be added to the open top of the carton to cool containers of drinks contained within it. As the ice gets melts, all or part of the resulting wastewater can remain inside the lower container. Cardboard packaging it can also include a feature that allows you to return it to close, in which the closing panels can be coupled together to close the open top of the cardboard container. A Secondary reinforcement starting piece can be extended through the bottom of the carton and upwards, entering the handles thereof, to increase the support capacity of the Carton container load.

Items housed within these embodiments of the carton can include such containers such as, for example, petaloid beverage containers bottled, metal beverage cans, glass bottles or plastic, or other containers such as, for example, used in the packaging of food and other products products. In order to show and not to limit the scope of the invention, the following detailed description gives know metal beverage containers in general cylindrical as they are arranged inside the carton. In this descriptive report, the terms "lateral", "extreme", "down", "lower", "upper" and "above" indicate specific guidelines regarding Vertical cardboard containers, fully assembled.

Figure 1 is a plan view of a piece multilayer initial (8) used to form a cardboard container (160) (shown in Figure 11) according to the first embodiment of the invention. The initial piece (8) is formed from a piece main initial (5) and a secondary initial piece (6) of reinforcement, adhered, laminated or otherwise attached to the piece main initial (5). In figure 1 the surface is visible inside or on the underside of the main initial piece (5). In the embodiment shown, the secondary starting piece (6) is adhered to the inner side of the main initial piece (5), although It can be attached to the outer side.

The multilayer starting piece (8) is "multilayer" since the layers of the initial pieces secondary and main together (6) and (5), which comprise the piece Initial multilayer (8), include substantial overlapping parts. In addition, a majority of the overlapping surfaces of the layers of the initial secondary and main parts (6), (5) can be attached adjacent to each other. For example, the pieces initials (5) and (6) have different perimeters or "fingerprints" and they don't have to overlap at all points, but at least substantially the entire surface of the secondary initial piece (6) may be adjacent and / or adhered to the inner side of the main initial piece (5).

As shown in figure 1, the piece initial (8) can be symmetric or almost symmetric with respect to a central transverse line (C_ {T}) and to a central line longitudinal (C L). The main initial piece (5) and the piece Secondary initial (6) may also be symmetrical with respect to the central transverse line (C_ {T}) and to the central line longitudinal (C L). Therefore, certain elements in the drawings may be indicated by reference numerals identical or similar to reflect partial or total symmetries in the initial piece (8).

Figure 2A is a plan view of the piece main initial (5), and Figure 2B is a plan view of the secondary initial piece (6) of reinforcement. Referring to the Figure 2A, the main initial piece (5) comprises a panel bottom (10), a first and second side panels (20) connected foldably on each side of the bottom panel (10) in lines of cross folding (21), respectively, a first panel upper side (32) foldably connected to the first panel lateral (20) in a transverse folding line (31), a first upper closing panel (42) foldably connected to the first upper side panel (32) in a transverse folding line (41), a second upper side panel (34) connected so foldable to the second side panel (20) in a transverse line of folded (33) and a second upper closing panel (44) connected foldably to the second upper side panel (34) in a line cross folding (43). An end panel (60) is connected to folding mode at each end of the bottom panel (10) in a line longitudinal folding (62). A panel (70) of the handle is connected foldably to a distal end of each end panel (60) in a longitudinal fold line (71). A characteristic (75) of racetrack type handle ("racetrack") may be formed on each panel (70) of the handle. Other handle features may be incorporated in the panels (70) of the handle. In this memory descriptive, the terms "extreme" and "lateral" are use to facilitate the reference, and do not imply sizes relative of the panels (20), (60).

A corner fin (80) is located in each bottom panel corner (10), extending between a panel side (20) and an adjacent end panel (60). Each fin of corner (80) comprises a first reinforcement panel (82) connected of folding mode to an end panel (60) in a transverse line of folded (21), a second reinforcement panel (86) connected so foldable to the first reinforcement panel (82) in an oblique line of folded (84), a third reinforcement panel (90) connected so foldable to the second reinforcement panel (86) in a transverse line folding (31) or (33) and a fourth reinforcement panel (94) connected foldably to the third reinforcement panel (90) in a line oblique folding (92). The first and second reinforcement panels (82), (86) can be defined by their edges, for example, by an arched or curved edge (96).

The first closure panel (42) may have a closing opening (48) formed therein. Closing opening (48) can be defined by, for example, a section detachable in the main initial piece (5), a section trimmed, a slit, or by other break lines of separation in the initial piece (5). The second closing panel (44) it can have a panel or a closing flap (50) defined by a distal end of the second closure panel (44) by a pair of transverse folding lines (51) and a curved cut (54) that extends between the fold lines (51). The curved cut (54) defines a closing projection (56) raised from the second panel closing (44). The closing opening (48) in the first panel of closure (42) is sized to receive the closing projection (56) in the assembled cardboard container (160) (figure 13).

Openings (46) for receiving the handle, which are extend longitudinally, can be formed in the panels (32), (42) and in panels (34), (44). The openings (46) of handle receiving are sized to receive handle fins from the handles of the assembled cardboard container (160) (figure 11). The handle receiving openings (46) may be defined by, for example, removable sections in the initial part (5), trimmed sections, crevices, or by other break lines of separation in the main initial piece (5).

Referring to figure 2B, the piece Initial secondary inner (6) reinforcement is configured to coating and / or to reinforce one or more selected parts of the main initial piece (5). The secondary starting piece (6) can have, for example, symmetry with respect to the central lines (C_ {L}), (C_ {T}). The secondary initial piece (6) comprises a secondary lower panel (102) that may have, for example, the same size or slightly smaller than the bottom panel (10) of the main initial piece (5) (figure 2A). A first and second panels secondary ends (104) are foldably connected to each end of the lower secondary panel (102) in fold lines longitudinal (103), and secondary panels (106) of the handle are foldably connected to distal ends of each panel secondary end (104) in longitudinal fold lines (105). Referring also to Figure 2A, each end panel secondary (104) can correspond generally in size and shape with the end panels (60) of the main initial piece (5), and the secondary panels (106) of the handle can correspond in general in size and shape with the panels (70) of the handle. Each secondary panel (106) of the handle can have a characteristic secondary (108) of the handle that generally corresponds in shape and function with a feature (75) of the handle on a panel overlap (70) of the handle. The characteristics (75), (108) of the handle they overlap and cooperate to form handles (144) of two layers in the assembled cardboard container (160) (shown in figure 11).

Referring to figures 1, 2A and 2B, the multilayer starting piece (8) can be formed by adhesion of the secondary initial piece (6) to the inner side of the piece main initial (5). Each of the panels (106), (104), (102), (104), (106) of the secondary starting piece (6) may be adhered to corresponding panels (70), (60), (10), (60), (70), respectively, of the main initial piece (5). Can be use glue strips, molten glue application on hot, or other adhesives and means to adhere to each other main and secondary initial pieces (5), (6). Lines longitudinal folding (105), (103), (103), (105) in the piece Secondary initial (6) will generally coincide with the lines of  longitudinal folding (71), (62), (62), (71), respectively, in the main initial piece (5), so that the initial piece multilayer (8) can be folded along the folding lines of overlap.

A method, by way of example, of assembling the multilayer starting part (8) in the carton (160) and cargo container of the cardboard container (160) with articles will be described to then referring to figures 1 to 11.

Figure 3 shows an initial stage of assembly in the method, by way of example, of assembly, in which the part Initial multilayer (8) is mounted on the cardboard container (160). Referring also to Figure 2A, the panels (34), (44), (50) fold back around the transverse line of folded (33) in the direction of the curved arrow (A). Panels (32), (42) fold back around the transverse line of folding (31) (not visible in figure 3). The first and second side panels (20) fold inwards along the transverse folding lines (21) in the direction of the curved arrows (B). The lower sides of the first panels reinforcement (82) is thus brought into contact with the secondary end panels (104) of the secondary starting piece (6) and adhere to them. The reinforcement panels (82) are they can adhere to opposite surfaces of the end panels secondary (104) by, for example, application glue, glue strips, other adhesives or other media. The stages of folded in the fold lines (21), (31), (33) can be present as discrete stages, or folds in the lines of folding (31), (33) can be carried out simultaneously with the folds in the transverse fold lines (21).

Referring to figure 4, the piece initial (8) folds inwards in the direction of the arrow curved (C) around the longitudinal fold lines (62) in the main initial piece (5) and the folding lines corresponding longitudinal (103) (not visible in figure 4) in the secondary initial piece (6). Figure 4 shows this folding operation at one end of the initial piece (8). He fold will be made at each end of the initial piece (8) to break previously (for example, release) the initial piece (8) by the longitudinal fold lines (62), (103).

Referring to figure 5, the piece Initial multilayer (8) partially mounted opens up exerting upward traction on the side panels (20) (no visible in figure 5) and swinging them around the cross fold lines (21) in the direction of the arrows curved (D). Side panels (20) and fixed panels (32), (42) and (34), (44) are also pivoted upwards around the fold lines (21), so that they extend generally vertical or straight with respect to the lower panel (10) Figure 6 shows the general vertical orientation of the panels (32), (42) and (34), (44).

Referring to figure 6, a end of the initial piece (8) folded around the lines of longitudinal folding (62) in the main initial piece (5) and of the longitudinal fold lines (103) in the initial piece secondary (6) in the direction of the curved arrow (E). Panels overlapping ends (60), (104) and overlapping panels (70), (106) of the handle remain vertical or generally vertical. The extreme opposite of the initial piece (8) will be folded in a similar way. In the Figure 6, the bottom panel (10) and the end panel (60) of the part Main initial (5) are covered by panels (102), (104) of the secondary initial piece (6), respectively, and the reference numerals (10), (60) are placed, therefore, in brackets. As shown in Figure 6, parts free (83) of the reinforcement panels (82) that are adjacent to the oblique fold lines (84) can be maintained without adhering to the secondary end panel (104) and can be curved away from the panel (104). With the end panels (60), (104) in position vertical, the partially assembled cardboard container has a shape substantially parallelepiped with an open top that It can be loaded with items.

Referring to Figure 7, the packaging of Partially assembled cardboard can be loaded with items. In the embodiment shown, the partially assembled cardboard container is loaded with eighteen twelve-ounce beverage containers (C), generally cylindrical, arranged in a 3 x 6 x 1 configuration. Overlapping end panels (60), (104) (shown in the Figures 2A, 2B, respectively) of the main initial pieces and secondary (5), (6) form a first and second end panels of two reinforced layers (110) at each end of the carton, and the overlapping bottom panels (10), (102) (figures 2A, 2B, respectively) form a reinforced two-layer bottom panel (120). The overlapping panels (70), (106) of the handle form panels of two reinforced layers (140) of the handle. The characteristics of overlap (75), (108) of the handle (figures 2A, 2B, respectively) in the respective overlapping panels (70), (106) of the handle are aligned with each other and can be attached to each other to form handles (144) two layers on each panel (140) of the handle.

Referring to Figure 8, a end of the partially assembled cardboard container with the second upper side panel (34), and fixed panels (44), (50), folded over the open top of the carton around the transverse folding line (33) in the direction of the curved arrow (F). The first upper side panel (32) and the First closing panel (42) is then folded around the transverse folding line (31) so that they overlap with the panels (34), (44). Alternatively, the first top panel side (32) can be folded around the fold line (31), followed by the fact that the second upper side panel (34) It folds around the fold line (33). As the panels (32), (34) fold inwards, the panels of reinforcement (90), (94) fold towards each other around the oblique fold lines (92). The opposite end of the container partially assembled cardboard folds similarly.

Referring to figure 9, a end of carton partially assembled with third parties reinforcement panels (90) and fourth reinforcement panels (94) (shown in figure 8) folded around the line longitudinal folding (62) in the direction of the curved arrows (G). The opposite end of the partially assembled cardboard container It folds similarly. In this case, one or both of the first upper side panel (32) and the first closing panel (42) are can adhere to one or both of the second upper side panel (34) and of the second closing panel (44). The panels (32), (34), (42), (44) Close an upper part of the cardboard container.

Referring to figure 10, it is shown one end of the cardboard container partially mounted with the panel (140) two layers of the handle folded around the lines of overlap folding (71) and (105) in the direction of the arrow curved (H). Referring also to Figure 9, the surfaces directed towards the inside of the panels (140) of the handle are contacted in this way with the reinforcement panels (90). Glue or other adhesives can be applied to the panels reinforcement (90), so that the panels (140) of the handle adhere to the same. The opposite end of the carton is folded and paste similarly to form the cardboard container (160), usually in parallelepiped, which houses the containers (C) shown in figure 11.

Referring to figure 11, the first upper side panel (32) and the first closing panel (42) are superimposed on the second upper side panel (34) and the second closing panel (44), although this orientation can be reversed. The  panels (32), (42), (34), (44) can be fixed together by adhesives, such as, for example, glue, to form a top closure (150). In this way, the top of the Cardboard container (160) is closed or substantially closed. Such as shown in figure 11, the panels (140) of the handle are extend in a transport position, generally upwards, from the end panels (110). The cardboard container (160) can be transport using reinforced multilayer handles (144) arranged in the panels (140) of the handle.

The panels (32), (42), (34), (44), which comprise the upper closure (150), can be held in place alternatively or additionally over the open top of the cardboard container, swinging the panels (140) of the handle in the direction of the arrows (I), and holding the fins (146) of the handles (144) into the openings (46) for receiving the handle, on each end of the cardboard container (160). In this configuration, the panels (32), (42), (34), (44) can be substantially flat at the top of the carton (160), forming the upper closure (150). The fins (146) of the handle folded into the opening (46) for receiving the handle can serve, for example, to keep the top panels and closing (32), (42), (34), (44) in a closed position on the top of the cardboard container, so that it is not necessary no adhesive to fix panels (32), (42), (34) in place, (44).

Figure 12 shows the cardboard container (160) in its expanded configuration, with the upper closure (150) open and with ice scattered on the contents of the cardboard container and housed in an interior enclosure (163) of said container. The container of cardboard (160) can be opened, for example, by pulling on the first closing panel (42), so that the panels (32), (42) are pulled by traction up and out in the direction of the arrow (J). Next, the panels (34), (44) can be dragged back in the direction of the another arrow (J). Referring also to Figure 8, a as the panels (32), (34) fold outwards, around the fold lines (31), (33), respectively, the reinforcement panels (94) fold outwards with respect to the reinforcement panels (90) (which adhere to the panels (106) of the handle) around the oblique fold lines (92).

As shown in Figure 12, with the upper part of the open cardboard container, can be introduced ice, cold water, or other cooling media, for example, in the inner enclosure (163) of the cardboard container (160), so that is in contact with the containers (C). Figure 12 shows a first height (H_ {C1}) of the closed cardboard container (160) generally adapted to the height of the side panels (20). The height (H_ {C1}) corresponds to the height of the container of cardboard when it is closed by panels (32), (42), (34), (44), as shown in Figure 11. A second height (H_ {C2}) indicates the height of the inner enclosure of the container of cardboard (160) when the panels (32), (42), (34), (44) extend up, as shown in figure 12. The panels (32), (34), (82), (86), (90), (94), (140) define an upper part of the interior enclosure (163), serving the fins (80), at each corner of the cardboard container (160), to join tightly substantially the corners of said container from the bottom panel (10) to the second height (H_ {C2}) when expanded. The Cardboard container capacity (160) expanded is increased, so both, opening the upper closure (150) and extending upwards the panels (140), (32), (34), (90), (94).

The cardboard container (160) can be transported using the reinforced multilayer handles (144) arranged in the panels (140) of the handle, when the cardboard container is in the Open and expanded configuration shown in Figure 12. Ice or the other refrigerants added, in addition to the containers (C), they can constitute a significant weight that the cardboard container (160). The two-layer section of the cardboard container (160), comprising the sections in which the initial piece secondary (6) overlaps with the main starting piece (5), adds significant resistance to said container in order to allow relatively heavy loads are transported in the packaging of cardboard (160). The reinforcement provided by the initial piece secondary (6) may be selected as target specifically, for example, for areas of the cardboard container (160) that require a reinforcement, so little cardboard is wasted when forming the cardboard container. In the embodiment shown, the panels (106), (104), (102), (104), (106) of the initial part Secondary (6) (Figure 2B) extend from a panel (140) of the handle, down one end panel (110), through the panel bottom (120), and through the opposite end panel (110) and the handle panel (140). Therefore, when a user carries the container cardboard using the handle (144), the initial reinforcement piece (6) is willing to support a significant part of the load.

Figure 13 shows the cardboard container (160) in its expanded configuration with the top of said container closed by panels (42), (44), (50). In this configuration, the panels (32), (34) generally extend vertical, so that the height of the inner container enclosure of cardboard (160) is (H C3). The third height (H_ {C3}) can be slightly smaller than the second height (H_ {C2}). The part top of the cardboard container (160) is closed by folding the first and second upper closure panels (42), (44) around the fold lines (41), (43) over the open top of the carton, respectively, in the direction of the arrows (K) The section of the closing flap (50) of the upper panel of closure (44) is re-curved around the fold lines (51) in the direction of the arrow (L), so that the projection of closure (56) generally extends downwards. The outgoing of closure (56) is moved down and pressed towards the inside the closing opening (48) in the first closing panel (42). The coupling of the closing boss (56) in the opening of closure (48) keeps the upper closure panels in place (42), (44) from the top of the cardboard container (160). He Cardboard container (160) can be transported using the handles reinforced multilayer (144) arranged in the panels (140) of the handle when the carton is in the expanded configuration and closed shown in figure 13. The top of the container cardboard (160) is closed, which reduces the probability that items accidentally fall out of it.

According to one aspect of the present invention, the added interior enclosure that is achieved by increasing the height of the cardboard container up to the second height (H_2) and up to third height (H_ {C3}) can be used to house a significant amount of cooling means such as, for example, ice, or even additional containers or other items which, for example, may require cooling. In addition to having a expanded inner enclosure, the cardboard container (160) can be continue transporting through the panels (140) of the handle on the expanded open configuration shown in figure 12 and in the Expanded closed configuration shown in Figure 13.

According to an embodiment of the present invention, the height of the inner enclosure of the cardboard container (160) increases, at least 10% when changing from closed settings shown in figure 11, which has the height (H_ {C1}), to the open and expanded configuration shown in the Figure 12, which has the height (H_ {C2}). The height (H_ {C3}) of inner enclosure of the cardboard container (160) in the configuration expanded and closed shown in figure 13 can be also at least 10% higher than the first height (H_ {C1}) of the cardboard container in the closed configuration, with a corresponding increase in the inner enclosure of said container. According another embodiment of the invention, the heights (H_ {C2}) and (H_ {C3}) are at least 25% greater than the first height (H_ {C1}).

Referring again to Figure 12, according to an exemplary aspect of the invention, the fins (80) can define, in part, a lower container (165), so less partially liquid tight, in the carton mounted (160). The upper edge or upper margin of the container lower (165) is indicated by dashed lines in the figure 12 and represents an area of the bottom of the carton (160) below which are not sealed seals of glued or glued lines through which water could leak or other liquids. That is, according to the first embodiment, no adhesive seal or other material bonding element through which fluid could escape from the cardboard container (160) is located therein in a position below the upper edge of the lower container (165). Referring also to the Figures 1 and 2A, the lower container (165) may be formed, therefore, from a continuous section of folded material of the initial piece (8). The height of the waterproof part at liquids in the container (165) below which there are no Paste lines are indicated as a height (H_ {R}) in the Figure 12. Referring to Figure 2A, the height (H_ {R}) it can generally coincide with the highest point at which reinforcement panels (82) are foldably connected to the reinforcement panels (84), along the curved edges (96).

The height (H_ {R}) can be defined, by example, as a function of a height of the cardboard container (160). For example, referring to figures 12 and 13, the lower container (165) can define a watertight part liquids that have a height (H_ {R}) that is at least approximately 15% of a height (H1) of the container of cardboard (160). In another embodiment, the height (H_R) of container (165) can be at least about 40% of a height (H_ {C1}) of the cardboard container (160). The height (RH) of the container can be increased or decreased by varying the fin geometry (82), (86), for example, to accommodate expected larger or smaller volumes of liquid in the cardboard container (160).

If desired, items can be placed additional in the cardboard container (160) after being opened. By example, if the containers (C) are beverage containers, it can be place ice on the containers (C) and remain inside of the cardboard container to cool the containers. To the extent that ice melts, the container (165) in the bottom of the container of cardboard (160) serves to retain all or part of the waste water from molten ice. The container (165) can serve also, for example, to accommodate fine particulate matter that they could escape, otherwise, through a glue line. Yes one or more containers (C) are damaged during transport or Cardboard container storage (160), bottom container (165) may serve to retain all or part of the Container contents broken.

The initial piece (8) can be manufactured, by example, of water resistant material to any degree desired, so that the liquid in the bottom of the container of cardboard (160) is kept in the lower container (165) during a selected amount of time. Therefore, the carton (160) may be manufactured so that the liquid retained in the lower container (165) is initially kept in the container of cardboard (160) at least until it reaches the height (H_ {R}).

Cardboard containers, according to the principles of The present invention may be formed from materials such as, for example, cardboard. Therefore, if exposed to water or to other liquids for prolonged periods of time, the carton can allow the passage of liquid through the moistened surfaces of said container due to permeability Partial material of cardboard packaging. In this memory descriptive, the expression "liquid tight" is used in general to define a section of a cardboard container that it is formed from a continuous section of material or a section without any paste line through which you could leak liquid or fine particulate matter, and expression "liquid tight" therefore defines some containers of cardboard that can become partially permeable to water over time due to prolonged exposure to water or other liquids

In the previous embodiments, the packaging of cardboard (160) is described as housing eighteen containers (C) of 12-ounce can type in a 3 x 6 x 1 configuration. However, other provisions of containers, containers, articles, and others elements, can be housed inside a cardboard container manufactured according to the principles of the present invention. For example, a carton package manufactured according to the principles of the present invention would also satisfactorily fulfill its function if said container was sized and shaped to contain items in other configurations, such as 3 x 4 x 1, 4 x 3 x 1, 3 x 6 x 1, 2 x 4 x 1, 2 x 5 x 1, 2 x 6 x 1, 4 x 6 x 1, etc., and variations multi-row of the above mentioned configurations. The dimensions of the initial piece (8) can also be altered, by example, to accommodate various forms of container. For example, it can accommodate 16-ounce petaloid bottles inside a carton package manufactured according to the principles of the present invention.

In the exemplary embodiments described above, the main and secondary initial pieces they can be formed from, for example, newspaper coated with clay (CCN), sulfate cardboard, solid, without whiten (SUS), and other materials. In general, the pieces initials can be made from cardboard with a gauge, at least about 14, for example, so which is heavier and stiffer than plain paper. The pieces initials may also be made of other materials, such as cardboard, or any other material, that have suitable properties to allow the carton to comply its function, at least in general, as described previously.

The initial pieces may be coated, for example, with a clay coating. The lining of clay can be printed for it with products, advertising, and with Other information or other images. The initial pieces can be then coat with a varnish to protect any printed information about them. The initial pieces are they can also cover, for example, with a barrier layer against moisture, on either side of them or in both of them. The initial pieces can also be laminated or coated with one or more sheet-like materials in panels selected or in panel sections.

The above embodiments can be described. as if they have one or several panels attached to each other by glue. The term "glue" is intended to understand all kinds of adhesives commonly used to fix on your Site cardboard container panels.

The term "line", as used in This description includes not only straight lines, but also other types of lines such as, for example, lines curved, curvilinear, angularly displaced or interrupted.

According to the realization by way of example of the present invention, a folding line can be any form of interruption or weakening in the pieces substantially linear initials, although not necessarily straight, which facilitates folding along them. Plus specifically, but not with the aim of reducing the scope of the In the present invention, some examples of folding lines include: incision lines; folding lines; a cut or a series of cuts that extend partially into the material and / or completely through it along a desired line of weakening; and various sequential combinations and / or of overlap of these characteristics by way of example.

In the embodiments shown, they are shown fold lines selected as including separate cuts to facilitate folding along said lines. If the cuts are below the bottom container part of the container of cardboard or adjacent to it, you can use less than 100% of the cuts to prevent leaks along the lines of creased. Alternatively, cuts or cuts can be omitted. incisions in or near the part of the container.

In the present specification, a "panel" or a "fin" does not have to be crushed or be Flat otherwise. A "panel" or a "fin" can comprise, for example, a series of interconnected sections generally crushed or flat.

For the purposes of this description, the expression "separation line" can be used to make general reference, for example, to a cutting line, a incision line, a bending line, a tearing line or a folding line (or various sequential combinations and / or of overlapping them) formed in an initial piece. A "break" line of separation is a line of separation that It is intended to break during normal use of the cardboard container. An example of a separation break line It is a torn line.
