Description

Object of the invention

[0001] The present invention relates to a cylindrical liquid packaging made of recyclable cardboard with a manual disc top closure and cord handle, and its use for containing and dispensing liquids, cardboard being its sole construction material, so that said packaging is fully recyclable.

[0002] We know of cylindrical packages with plastic pouches inside containing liquid and semi-liquid products such as wines, liqueurs, syrups, oils, milk, infusions..., which are distributed through a tap integrated into said pouch, the latter protruding from the packaging through an opening cut in its lower band.

[0003] Similar cylindrical packages are known, made with a cardboard tube and two tinplate closure discs. The upper disc has a tab for manual fastening to close the tube. The lower disc is attached to the tube at the factory using special machines, while the upper disc must be attached by the packer after the liquid pouch has been inserted. Therefore, the packer has no choice but to use a machine to attach the tinplate disc with a tab that seals the top of the package. Handling these tinplate discs presents a high risk of pinching and cuts.

[0004] Because of the composition of these known packages which include a cardboard tube, two tin discs and the plastic bag with tap which protrudes outside of said package, these packages have the disadvantage that their recycling is very complicated and dangerous, since they include three different materials, cardboard, plastic and tin, all three usually ending up in the household waste container and, if the user attempts to recycle them, the removal of the tin discs presents risks during their handling.

[0005] However, the cylindrical recyclable cardboard packaging of the present invention consists of a cardboard tube with inward-folding openings. The upper opening is closed by a cardboard disc with a cord handle attached to the disc itself. This allows the disc to be pulled out after being manually inserted into the tube and adjusted when held by the handle. The lower opening is adjusted by machine at the factory. The manual closing disc is inserted diagonally by the packer with simple pressure and is then secured against the upper rim of the tube by pulling the handle's cord upwards or simply by carrying the packaging by the handle's cord and allowing the closing disc to snap into place under the weight of the load.

[0006] The packer receives the package with the lower cardboard disc factory-attached to the bottom rim of the tube. They insert the liquid-filled pouch through the top opening and then attach the closure disc by inserting it through the same opening and adjusting it under the upper rims of the tube. The packer then secures the closure disc by pulling on the curved cord handle integrated into the disc itself. The tube has a cut-out window in its lower band, allowing it to be ruptured so the packer can remove the dispensing tap through this already open window.

[0007] The advantages of the present invention are, besides the fact that the packaging is fully recyclable, that the assembly of its manual closure does not require any machine, the closure disc being able to be mounted manually, which makes it a packaging suitable for both small and large productions.

[0008] For clarity regarding the packaging description, it is delivered upside down, with a hand-adjustable cardboard disc positioned under the rim of the tube's top opening. The packer simply inserts the liquid-filled pouch into the tube and then, using a slight tilt, inserts the drawstring-handle closure disc through the top opening. The disc's shape facilitates insertion into the tube but hinders removal, as it is horizontally aligned with the rim, preventing it from slipping out. Once the packer has positioned the package, pulling on the handle while manually carrying the package allows the closure disc to slide upwards until it is fully seated under the rim in the tube's top opening.

[0009] Another advantage of this packaging is that once the end user has consumed the contents of the pouch, they simply remove the top sealing disc by gently pressing one side inwards and pulling the handle outwards, then immediately remove the plastic pouch, the materials being separated so that they can be deposited in their corresponding recycling containers, thus ultimately achieving the goal of responsible recycling.

[0010] The materials used consist of fully recyclable structural elements manufactured in an innovative way from cardboard only, making it an original, economical and eco-responsible system as well as biodegradable which adapts the geometry of the invention to the technical requirements of the use.

[0011] The industrial application of the present invention relates to the sectors of packaging recycling, and more specifically to the recycling of one hundred percent recyclable cardboard packaging. Context of the invention

[0012] Although no invention identical to the one described has been found, we present below the documents found which reflect the relevant state of the art.

[0013] Thus, document ES2823925A1 refers to a process for obtaining a recycled material from multilayer polyethylene packaging, which is post-consumer and / or post-industrial packaging. It therefore concerns obtaining a material through the processing of multilayer PET packaging, and not a structural basis, as proposed in the invention applied for.

[0014] Document EP3634865A1 refers to a container for liquids which is made up of at least two layers (11, 12) of a cardboard composite material made from kraft paper (18) wound in a direction perpendicular to its axis to obtain a hollow cylinder as the body of the box (2), wherein the connecting joints (15, 16) of the at least two layers (11, 12) of cardboard composite material are displaced at certain points relative to the circumference of the windings and one side (6) of the open hollow cylinder thus formed is closed by a base element (4) and the other open side (7) of the hollow cylinder or the body of the box can be closed or is closed in the same way by a lid (5) with a closure after packaging, characterized in that, for the innermost layer, the edges are butted together in the winding direction, while the innermost sheet of the innermost layer, i.e. the barrier sheet,overlaps the kraft paper (18) on its edges in the winding direction, or the edge areas of the innermost layer overlap in the winding direction, wherein, in both cases, the overlaps are in contact with each other after being folded at right angles, with their barrier sheets away from the wound layer (11), are welded together and then folded over one side of the layer and glued thereto, while for each additional layer (14, 12), the edge areas overlap in the winding direction, wherein the overlap areas (45) are cut or ground over their entire thickness at an angle on a chamfered surface (44) or forming a bearing (21), so that the overlap areas overlap positively and said overlap areas (45) are no thicker than the thickness of the cardboard compound material itself.

[0015] Document ES2673488A1 proposes a packaging (1) applicable to the storage and preservation of food products, which includes walls (1a, 1b, 1c, 1d, 1e, 1f) arranged to define an enclosure with at least one opening (A) for the introduction of food products into it, where at least a part of said walls (1a, 1b, 1c, 1d, 1e, 1f) allows the passage of air through the wall to ventilate the packaging, the packaging being characterized in that at least one of its walls (1a, 1b, 1c, 1d, 1e, 1f) contains, inside or against one of its faces, at least one preservative agent that is protective against moisture and suitable for food contact.

[0016] Document ES1009842U describes recyclable packaging of the type used to contain small articles, essentially characterized in that it is made from a sheet of flexible material, having a general rectangular configuration, to which is glued by conventional means and in its middle area a second sheet of an identical or similar material, having a series of cutouts on its main branches which generally adopt the trapezoidal configuration, the cutouts located on the various branches being of different sizes.

[0017] Conclusions: As the research conducted shows, none of the documents found solve the problems raised in the same way that the proposed invention does. Description of the invention

[0018] The present invention consists of a cylindrical package made of recyclable cardboard with a manual disc closure at the top, comprising a cord handle, and its use for containing and dispensing liquids. The use of cardboard as the sole construction material adapted to the geometry of the invention renders said package fully recyclable.

[0019] The recyclable cardboard cylindrical packaging of the present invention consists of a cardboard tube with the two openings folded inwards, the upper opening being closed manually by the packer who inserts a cardboard disc with a cord handle under its rim and the lower opening being closed by a simple disc fitted by machine in the factory, the upper disc being sufficiently flexible for the packer to insert it with a simple pressure and wedge it under the upper rim of the tube.

[0020] The packer receives the package with the cardboard disc factory-attached to the bottom closure of the tube. They then insert the liquid-filled pouch into the package through the top opening of the tube, and then attach the disc closure by inserting it through the top opening of the tube under its upper rim. The disc closure is fully engaged by the weight of the package with the liquid pouch when carried by hand. The tube has a cut-out window in its lower band, allowing it to be broken open so that the user can remove the dispensing tap through this already open window.

[0021] The assembly of its manual closure requires no machine, the closing disc is mounted manually.

[0022] For clarity regarding the packaging description, it is delivered upside down, with a factory-fitted, pressure-fitted cardboard bottom disc that is open from the outside. The packer simply inserts the liquid-filled pouch through the top opening, then inserts the disc with the cord-shaped handle through the same top opening of the tube, using a slight tilt. The disc's shape facilitates insertion into the tube, but not removal, as its circular shape fits under the tube's top rim, preventing it from slipping out. Once the packer has positioned the container, under the weight of the liquid pouch, when the package is lifted by hand, the disc with the handle fully locks into place, moving upwards and fitting perfectly into the top of the tube.The end user can also pull the cord handle until the locking disc is manually engaged.

[0023] Once the end user has consumed the contents of the pouch, they remove the disc with handle by gently pressing one side inwards and pulling it outwards by the handle, then immediately remove the plastic pouch, the materials being separated so that they can be deposited in their corresponding recycling containers, thus ultimately achieving the goal of responsible recycling.

[0024] The materials used consist of fully recyclable structural elements manufactured in an innovative way from cardboard only, making it an original, economical and eco-responsible system that adapts the geometry of the invention to the technical requirements of use. Brief description of the drawings

[0025] For a better understanding of this description, drawings representing a preferred embodiment of the present invention are attached: Figure 1 : Perspective view of the cylindrical packaging. Figure 2 : Perspective view of the cylindrical top-closing package with handle and tap for dispensing the liquid contents of the bag. Figure 3 : Perspective view of the closing disc.

[0026] The numerical references appearing on the said figures correspond to the constituent elements of the invention. Description of a preferred embodiment

[0027] A preferred embodiment of the cylindrical recyclable cardboard packaging with a manual disc closure at the top and its uses, which is the subject of the present invention, with reference numerals, is based on a cylindrical structure for containing and dispensing liquids made entirely of recyclable cardboard, consisting of a cylindrical tube (1) with a disc closure at the top (2) made of cardboard with a handle (4) and a bottom closure without a handle. The use of cardboard as the sole construction material of the invention renders said packaging (1) entirely recyclable.

[0028] The openings of the cylindrical tube (1) are folded inwards, the lower opening being closed by a factory-pressed cardboard disc (2) and the upper opening being manually closed by a cardboard disc (2) with a cord-shaped handle (4) sufficiently flexible for the packer to insert the disc with a simple press, said disc (2) remaining wedged under the upper rim of the tube (1).

[0029] The liquid-filled pouch is inserted by the packer into the tube (1) through its upper opening, which is then closed by pulling on the cord-shaped handle (4) of the disc (2) until it is fitted under the rim. This fitting is reinforced by the weight of the pouch when the package is carried. The cylindrical tube (1) has a cut-out window (10) in its lower band, which allows it to be broken open so that the packer can remove the dispensing tap (6) through this window.

[0030] The assembly of its manual closure does not require any machine, the closing disc (2) with handle (4) being assembled manually.

[0031] For clarity regarding the packaging description, it is delivered with the factory-fitted cardboard top closure disc (2). The packer simply inserts the pouch (4) containing the liquid through the top opening, then gently tilts the disc (2) with handle (4) under the rim of the same top opening. The shape of the disc (2) with handle (4) facilitates its insertion into the cylindrical tube (1), but not its removal, as the tube's top rim prevents it. Once the package is in an upright position, the weight of the pouch containing the liquid completes the insertion of the disc (2) with handle (4), moving it upwards and fully fitting it into the top of the tube (1). The packer can also pull the cord handle (4) to manually insert the closure disc (2).

[0032] Once the end user has consumed the contents of the pouch, they remove the upper disc (2) with handle (4) by gently pressing on its side and pulling the handle (4) outwards, then immediately remove the plastic pouch, the materials being separated so that they can be deposited in their respective recycling containers, thus finally achieving the goal of responsible recycling.

[0033] The materials used for the packaging consist of fully recyclable structural elements manufactured in an innovative way from cardboard only, making it an original, economical and eco-responsible packaging that adapts its geometry to the technical requirements of use.
