Description

OBJECT OF THE INVENTION

The present invention relates to a container for liquid bags, which is constituted in cardboard and has a window corresponding to one of its side walls to expose the corresponding discharge mouth of the bag contained inside.

The object of the invention is to achieve a container of the type referred to but of great resistance, which allows large bags to be accommodated, thanks to a reinforced structure, which allows its stacking with other equal ones, as well as its arrangement in a pallet for loading and unloading of the same with the respective bag full of liquid inside.

BACKGROUND OF THE INVENTION

Although cardboard containers for liquid bags are known, such as the classic "bag in box" used for wine, these are suitable for relatively small volumes of liquid, so that a certain volume is exceeded, the very nature of the container makes that it does not support the loads to which it is subjected.

DESCRIPTION OF THE INVENTION

The container that has been recommended has been conceived to solve the problem described above, in a simple way but with great efficiency, allowing to contain large capacity bags, such as 250 and 500 liter bags, without deforming the container in its handling .

To do this, and more specifically, the container of the invention is obtained from the development of two rectangular sheets of cardboard, and in combination with a third sheet whose function will be exposed later, so that the two main sheets have lines cutting and bending to form in one case, the body of the container, with its bottom, its side walls and closing flaps, and in the second case to form an envelope of said body of the container, thus defining a double vertical wall, which reinforces the structure, while the third piece that participates in the constitution of the container is materialized in a rectangular piece, also of cardboard, with three equal sectors, foldable together, to form a triple wall that is positioned in correspondence with the planned window on one of the side walls of the container, to exit the outlet of the inner bag, so that the weakening caused by the axis Ution of said window is seriously reinforced by this piece, also affected by formally and positionally shaped recesses coinciding with said window, so that they are facing in its assembly, together with a similar window practiced on the inner reinforcement piece.

The wrapping piece is mounted on the piece that constitutes the main body of the container by sliding plug on it, so that once both pieces are superimposed, and once the third reinforcement piece is established, said container is closed by means of flaps or extensions that derive from the upper edge corresponding to the body of the container, with the particular feature that said flaps have holes of rectangular configuration for the placement of plastic parts that make a retention in the position of such flaps in the closed position.

In addition, in correspondence with the fold line of one of the side faces of the container body and the respective flap or extension of the upper closure, at least two holes are provided for the passage of respective straps that hold the container in its fully stable closing position for handling, preferably on a pallet or base in question.

As a consequence of the double wall formed by the two pieces that participate in the constitution of the container, as well as the reinforcement that constitute the three superimposed and folded sectors of the piece located in the window of the bag's discharge mouth, the resistance of said container is greatly increased, being sufficient to allow to contain large volumetric liquid bags, and carry out its handling without risks of alterations in the configuration of said container.

DESCRIPTION OF THE DRAWINGS

To complement the description that will then be made and in order to help a better understanding of the features of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where for illustrative and non-limiting purposes, the following has been represented:

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the container of the invention is constituted by a main piece (1), an inner envelope (2), and a reinforcement piece (3), all of them materialized in cardboard, so that the main piece (1) presents a rectangular development, with transverse fold lines to form the respective side walls (4) of the rectangular prismatic configuration body that is obtained in its assembly, counting for it with extensions (5) that define the bottom of the container.

In opposition to said extensions (5) the side walls (4) have extensions that will constitute the flaps (6) of the upper closure of the container.

In correspondence with one of the side walls of the body of the container obtained from the main piece (1), a recess (7) is provided in its lower and middle area of said wall, recess (7) that is faced with another recess (8) defined in the envelope (2) of tubular configuration, and that is internally coupled by plug on the body obtained from the main part (1).

Said envelope (2) presents in correspondence with each of its side walls

(9) with lower flaps (10) that in the assembly fold inwards, reinforcing the bottom of the container, determining a double wall with respect to the side walls of the main body (1) of the container, providing great resistance to container set.

Consequently, in the assembly and assembly of the two pieces (1) and (2) a container is formed in which the recesses (7) and (8) face each other, to form a window through which it is left see the discharge mouth (11) of the bag (12) to be contained in the container, with the particularity that said window is reinforced with the reinforcement piece (3), determined by three sectors (3 ') equal to each other, foldable overlapping to form a triple wall, which corresponds to the window of the envelope (2), said sectors (3 ') being affected by windows (13) for passage of the discharge mouth of the internal bag.

Said bag has an upper filling mouth (14) that is hidden by folding into the upper flaps (6) of the main body (1).

5 On the other hand, it is envisaged that said closing flaps (6) have holes as small rectangular windows (15) facing each other in pairs so that in the closing situation they can insert plastic parts (20) and achieve a perfect immobilization and stabilization of the container.

10 On the other hand, in correspondence with the fold line of one of said extensions or flaps (6) and the respective side wall (4), holes (16) are provided for passage of strips (17), guided by recesses ( 18) on the edges of the flaps (6), which embrace the body of the container in its total closing situation as shown in Figure 6, said container being arranged on a pallet (19).
