Description

DESCRIPTION

Liquid transport container

Technical sector

The sector in which the invention falls is that of containers for storage or transport of articles or materials; more specifically rigid or semi-rigid containers with a 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 through a tap that is inserted into the container at the moment in which its consumption begins. The liquid leaves the bag without air entering its interior and therefore it collapses inside the box. This type of container has found its field of application as a beverage dispenser, but its use is not recommended in certain products, for example oil, because a significant amount of product would be wasted given its smoothness or ability to adhere to the walls of the thermoplastic bag. It can be used in cleaning products or products that require a certain amount of caution during handling, since it is very easy for the liquid to spill. In addition, once the tap is in place, it cannot be removed. Remove until all the contents of the container have been consumed, making it difficult to store from that moment on.

They are also known "bottle-in-box" containers, 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 provide anything new on a practical level since they work just like 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 piece embedded 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 thermoplastic bag containers. For example, patent US2005133578 describes a bag in a box in which said bag is made of a PET thermoplastic material. But these PET bag-in-box containers are unsuitable for storing and transporting certain products, because when subjected to vibrations, for example during transportation, wrinkles and cracks occur in the walls of the PET container causing fluid leakage, which are not acceptable both from a consumer and safety point of view.

Both bags and bottle-in-boxes should be disposable, but unlike soda and other beverage bottles that are formed from recyclable plastic such as PET, bottle-in-boxes and particularly bags are difficult to recycle. because they are made of different materials that must be separated previously and it is almost always impossible because there are internal joints at some points.

In both bags and bottles, the product is first packed in the bag or bottle, closed or corked, and then the container is placed in the already assembled box, which is also closed later. The inner container is always filled first and the box is only secondary packaging, which may or may not be supplied by the manufacturer of the bottle or bag.

Explanation of the invention

Based on the prior art, an object 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, Then, in parallel, assemble the box and insert the empty, unstoppered bottle into it, and finally glue and close the box around the bottle. The container thus formed is palletized and is ready to fill and stopper in a packaging line of conventional type cannula, which can be located in the factory of the product contained inside, in a place totally independent from the one in which the container was manufactured.

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

Another object of the invention is to facilitate and simplify the recycling of the used container. 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.

Description of the drawings

To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to this specification in which, for illustrative and non-limiting purposes, the following has been represented:

Figs. 1-2 show a bottle-type container (2) in a box (1) closed and the upper flaps (12, 13) of the box (1) partially open.

Figs. 3-5 represent the bottle (2) in perspective and side elevation views.

Fig.6-7 show the box (1) partially assembled, from two opposite angles.

Fig. 8 represents a cross-sectional view of the box (1) closed and with the bottle (2) inside.

Embodiment 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 is made up of a box (1) that has gripping means for its transport and emptying and internally contains a bottle (2). , whose neck (21) protrudes from the upper part 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 thereof. 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, being so thin, its walls could not support 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 parallelepiped configuration stands out, which at 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), its sides protrude from one side 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).

At the bottom, the bottle (2) also has a recess (23) on the opposite side to that of the neck (21) to leave space 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, die-cut and folded, which forms a structurally resistant outer lining in which at least one upper handle (11) has been formed, consisting of a cross section which, when sinking inwards, allows the fingers of the hand to be inserted from below into 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 parallelepiped configuration, vertically horizontal, similar to a carton type brik. The only structural difference is observed in the upper base, since this is preferably not parallel to the lower one since it is inclined in such a way that the opposite side to the one where the neck (21) of the bottle is located is equal height than this once the cap is placed, with the obvious purpose of allowing the stacking of two units of this type of packaging, without there being an inclination of the column formed by them.

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

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

- Respective side flaps (14) that present, in correspondence with the neck (21) of the bottle (2), some semicircular cuts (18) that fit into 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 die-cut (11) that defines a window through which the hand is inserted to grasp the container.

The side flaps (14) of the upper base present, in correspondence with the punching (11) of the flap (13), respective windows (15) that allow the passage of the hand to the interior hole of the box (1), above of the recess (22) for gripping the container (see Fig. 8).

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

This container is produced on a continuous manufacturing line, first the bottle is blown, then in parallel the box is assembled in such a way that the unstoppered and empty bottle is introduced inside the cardboard box (1), which is glued and close around the bottle (2). The container is then palletized and is ready for filling and capping on the packaging line.

In summary, the manufacture of the container follows this process: Bottle blowing >> box shaping >> empty bottle insertion >> box closing >> empty container palletizing.

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 close, already labeled, since the cardboard box 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 with an original form 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 grabbed by the bottom to facilitate tilting. and poured.

Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential characteristics of the invention that are claimed below:
