Description

DESCRIPTION

Container for transporting liquids

Technical sector

The sector in which the invention is framed is that of containers for storage or transport of articles or materials; more specifically of rigid or semi-rigid containers of polygonal cross section, made of paper and plastic materials, to contain semi-liquids or liquids, in individual containers or receptacles.

State of the art

Currently there are "bag-in-box" type solutions on the market, consisting of a bag of flexible thermoplastic material that goes inside a box. The liquid contained in this container is extracted by gravity from the bottom using A tap that is inserted into the container at the moment in which consumption begins. The liquid leaves the bag without air entering the bag and therefore it gradually collapses inside the box. This type of container It has found its scope as a beverage dispenser, but its use is not recommended in certain products, for example oil, because a significant amount of the product would be wasted given its unctuousness or ability to adhere to the walls of the thermoplastic bag. It can be used in cleaning products or products that require some caution during their handling since it is very easy for some liquid to spill. Furthermore, once the tap is placed it cannot be r Remove until the entire contents of the container have been consumed, making it difficult to store from that moment on.

Container-in-box type containers are also known, which are containers with a bottle of rigid thermoplastic material included inside a box. The liquid is extracted by opening a cap and pouring through the upper part of the bottle. Consequently, as the liquid comes out, the air replaces it inside. These containers do not add anything new at a practical level since they work the same as a bottle, but they represent a different and improved presentation of the product, which is why they have also found their market niche.

In the patent literature there are several references to these types of containers; For example, document US2006180643 describes a bag-in-box container that has a recessed piece in the neck of the bag, which is fixed in the outer cardboard box to emulate a rigid neck, so it has the appearance of a drum. .

More recently, collapsible blow molded containers from polyethylene terephthalate (PET), such as those used to make soft drink and juice containers, have been suggested as an alternative to containers with a thermoplastic bag. For example, patent US2005133578 describes a bag in a box in which said bag is made of a PET thermoplastic material. But these boxed PET bag containers are unsuitable for storing and transporting certain products, as when subjected to vibrations, for example during transportation, wrinkles and cracks occur on the walls of the PET container causing fluid leakage, that are not acceptable from both a consumer point of view and safety.

Both the bags and the boxed bottles must be disposable, but unlike the bottles for soft drinks and other beverages that are made from recyclable plastic, such as PET, boxes with bottles and particularly with bags are difficult to recycle. because they are made of different materials that must be separated beforehand and it is almost always impossible because there are internal joints at some points.

In both bags and bottles, the product is first packaged in the bag or bottle, it is closed or capped and then the container is placed in the already assembled box, which is subsequently also closed. The inner container is always filled first and the box is only a secondary package, which may or may not be supplied by the manufacturer of the bottle or bag.

Document JP2012162288A discloses a container formed by a paper box that internally includes a bottle, the neck of which protrudes from the top of the box. It is a one-piece molded PET bottle. This container lacks gripping means which makes it impossible to use given the fragility of the paper box and of the bottle itself. On the other hand, when the box is made of paper, it is formed by gluing several flaps together, which makes it difficult to disassemble the set for recycling.

Explanation of the invention

Based on the prior art, an objective of the present invention is to provide a container for transporting liquids of the bottle-in-box type, which from its manufacture behaves like a container, that is, it is manufactured in a continuous line by first blowing the bottle, to then in parallel assemble the box and introduce the empty bottle without corking and finally glue and close the box around the bottle. The container thus formed is palletized and is ready to be filled and corked in a conventional cannula packaging line, which can be located in the factory of the product contained within, in a totally independent place from the one in which it was manufactured. the container.

Another objective of the present invention is a container that allows shipping and commercialization by electronic commerce without having to use a second outer packaging box for transport, in this case being sufficient to protect the bottle-box by means of a conventional packaging.

Another objective of the invention is to facilitate and simplify the recycling of used packaging. This objective is achieved because the outer cardboard box is easily separable from the inner PET bottle, so that the user can recycle both components separately. In addition, this container uses PET bottles with thicknesses between 0.15 and 0.30 mm, which significantly reduces the generation of waste from this material, while making the bottles more wrinkled so that once empty they occupy a minimum volume.

In order to achieve the proposed objectives, mentioned in the previous section, the invention proposes a container to contain liquids, which has the characteristics of claim 1.

Implementation of the invention

As can be seen in the referenced figures, the container for transporting liquids of the present invention is of the type that consists of a box (1) that has gripping means for its transport and emptying and internally encloses a bottle (2) , whose neck (21) protrudes from the top of the box (1).

The bottle (2) is a single piece, molded in PET, with thicknesses between 0.15 and 0.30 mm depending on its capacity and certain reinforced areas of it. With these thicknesses, the bottle is watertight, but it is not structurally resistant and, by itself, it could not function as a container in retail distribution systems since, as its walls are so thin, it would not be able to withstand the vertical storage load; However, its weight has been reduced to the maximum so that its recycling does not generate a significant amount of waste.

The bottle (2) (see Fig. 3-5) has a special design, in which its substantially parallelepipedic configuration stands out, which on the top has a neck (21) inclined towards one of the sides, with an angle of inclination between 8 and 20 °, so that, once inserted into the box (1), the sides of the box appear on one side in order to facilitate pouring.

On the side opposite the neck (21) the bottle (2) has a recess (22) that accommodates a handle (11) defined in this area of the box (1).

Internally, the bottle (2) also has a recess (23) on the opposite side to that of the neck (21) to make room for a second handle (17) formed in the box (1) in correspondence with said recess.

For its part, the outer box (1) is made of a single piece of paper fiber, stamped and folded, which forms a structurally resistant outer covering in which at least one upper handle (11) has been formed, consisting of a cross section that when sinking inwards allows the introduction of the fingers of the hand underneath in the gap that remains between the upper base of said box and the recess (22) of the bottle (2).

As can be seen in the figures, both the bottle (2) and the box (1) have a substantially parallelepipedic configuration, vertically horizontal, similar to a carton-type carton. The only structural difference is observed in the upper base, since preferably this is not parallel to the lower one since it is inclined in such a way that the opposite side to that in which the neck (21) of the bottle is located is the same the height of the latter once the cap is in place, with the obvious purpose of allowing the stacking of two units of containers of this type, without there being an inclination of the column formed by them.

The box (1) is closed on both bases by four flaps (13, 14, 14, 16) that are an extension of its lateral faces. In the upper base (Fig. 6-7) you can see:

- A flap (16) located on the side coinciding with the neck (21) of the bottle (2), which has a circular window (12) that fits into it, keeping it immobilized.

- Both side flaps (14) that present in correspondence with the neck (21) of the bottle (2) some semicircular cuts (18) that fit in the neck (21), collaborating in its immobilization. Y,

- A flap (13), opposite the side from which the neck (21) of the bottle (2) protrudes, which has a transverse cut-out (11) that defines a window through which the hand is inserted to grasp the container.

The side flaps (14) of the upper base have, in correspondence with the cut-out (11) of the flap (13), windows (15) that allow the hand to pass into the interior hole of the box (1), above of the recess (22) to grip the container (see Fig. 8).

As can be seen in Fig. 9, on the flap or flaps that concur around the neck (21) of the bottle (2) threads or fits a clamping piece (3) in the closed position of said flaps, with the primary objective not having to use any type of glue to join them together and that the container is easier to disassemble for recycling.

The lower base of the box (1) has a set of flaps similar to the upper one, but in the reverse position. The flap located below the recess (23) of the bottle (2) has a transverse cutout (17) that defines a window through which the hand is inserted to be able to grasp the container. And, the side flaps of the lower base have, in correspondence with the die-cut (17), windows (15) that allow the hand to pass into the interior hole of the box (1), above the recess (22) for the grip of the container. Logically there is no circular window equivalent to (12) since the bottle at its lower base does not have another neck (21).

This container is produced in a continuous manufacturing line, first the bottle is blown, then in parallel the box is assembled in such a way that the uncapped and empty bottle is inserted into the cardboard box (1), which is glued and closes around the bottle (2). The container is then palletized and ready to fill and cap on the packaging line.

In summary, the manufacture of the container follows this process: Blowing the bottle >> shaping the box >> inserting the empty bottle >> closing the box >> palletizing the empty containers.

The packaging of the liquid product follows this process: Reception of the empty containers >> filling of the containers >> capping of the containers once filled >>> palletizing of containers filled with the corresponding liquid.

In addition to the aforementioned advantages, this new type of packaging provides several advantages: The packer receives a container ready to fill and cover, already labeled as a cardboard box, it has already been personalized before settling, with which he does not even have to adapt his line conventional packaging. The consumer will find a container with a unique design and an original way of presentation and that is also very easy to use, since not only can it be poured like a bottle, but it can also be grasped by the bottom to facilitate its inclination. and dumped.
