INTRINSIC CLOSURE FOR FLEXIBLE WALL CONTAINER

Abstract

 Intrinsic closure for flexible wall container comprising an outlet mouthpiece having at its upper portion a seaming line (2) and a handle (4) for carrying manually the bag, provided with an opening (3) which starts at the top and extends in the form of a tubular neck (5) which can be gradually folded to form a folding (6) which remains housed in a cap (7), said cap forming part of the body of the bag or container (1) and linked to the latter by means of a tether (8), the cap (7) and tether (8) being connected to the bag (1) and obtained in the proper configuration of the latter, in order to impede the outflow of liquid contained in the bag (1), the folding (6) remaining in its position inside the cap (7).

Description

OBJECT OF THE INVENTION

[0001] The invention relates to an intrinsic closing device for flexible wall container, applicable to containers which having any shape and being formed in a flexible material, like resistant plastic, presents the particular feature of including a peculiar closing system which is simple, it does not require any closing means at all and nevertheless it produces an efficient closing in order to hinder the emergence of a liquid contained in the bag itself.

FIELD OF THE INVENTION

[0002] This invention has its application within the closing device manufacturing industrial sector for containers or vessels.

BACKGROUND OF THE INVENTION

[0003] It is known a type of flexible wall bag, preferably formed by plastic material, sufficiently resistant so that the bag can contain a liquid and can be manually transported without breaking.

[0004] This type of bags which can have any geometric shape, presents the peculiarity that in the upper part a handle and a narrow filling and emptying opening is defined, since this type of bags are preferably foreseen to be filled up with a liquid in case of a temporary need, and/or in any required circumstances.

[0005] What it is obvious is that because of being a simple bag and because its manufacturing is inexpensive, it is not commercialized with an efficient closing device, and not even with a closing device that may hinder the emergence of the liquid contained therein at the time in which an inclination of the bag is produced.

[0006] The obvious solution to the existing problem at present on this matter, would be to be able to count on an intrinsic closing device which would allow its application in a flexible wall container, which would avoid the above mentioned existing disadvantages.

DESCRIPTION OF THE INVENTION

[0007] The intrinsic closing device for a flexible wall container that the invention proposes, is applicable to containers that, although being able to have any shape and being formed by a flexible wall of any nature, has the peculiarity that the filling and/or emptying opening thereof is determined by a tubular long neck which allows to successively bend it several times, remaining in that position secured by a cap that preferably will be linked to the container and that can be made out from its wall during the shaping phase thereof.

[0008] In this way a totally efficient closing device is achieved which allows the container to hold a liquid and to avoid its spilling even when such container would be placed in an inclined position, or even lying, which allows its transport loaded with liquid in a vehicle or in any other conventional means, i.e. without needing to continuously carry it held by the handle in the upright position thereof.

[0009] As it can be verified, the closing device is extremely simple, since it is based in a long neck which in virtue of its length allows a succession of foldings thereof, remaining this one, once it is totally folded through these foldings, inside of a cap linked to the container itself, forming such cap an integral part thereof and being sufficient to pull out such cap in order to liberate the neck and to be able to empty the liquid contained in the container itself, that on the other hand having a discharge neck of considerable length, makes possible an emptying action substantially more efficient and rational that when the container includes a simple discharge opening for the liquid.

DESCRIPTION OF THE DRAWINGS

[0010] In order to complement the description which is being made and with the object of helping to achieve a better comprehension of the characteristics of the invention, it is attached to the present specification as integral part thereof, a set of drawings in which with illustrative but not limiting character the following has been represented:

Figure number 1.- Shows a representation according to a lateral elevation view of a bag shape container, made according to the invention, which, having a conventional configuration and handle, includes a long neck for the liquid discharge and a receiving and retention cap for the neck in the phase of multiple folding thereof, which corresponds to the closing position of the bag, being in its context the object of the invention in reference to an intrinsic closing device for flexible wall container.

Figure number 2.- Shows a representation of the object exhibited in figure number 2, that is of the bag, according to a general perspective thereof with the folded neck by successive foldings.

Figure number 3.- Finally shows a view of the bag exhibited in the previous figures, with a folded and retained neck in the interior position of the cap linked to the bag itself and which is an integral part thereof.

PREFERRED EMBODIMENT OF THE INVENTION

[0011] Looking at these figures it can be seen how the intrinsic closing device for a flexible wall container is formed by a bag (1), which as it has been mentioned before it can have any shape or may be provided with flexible walls, although these ones may have shapes of any nature, having the peculiarity that in the upper part thereof, that is of the bag, it includes a welding bead (2) which practically closes it as a whole with the exception of a determinant section (3) of the opening for filling and emptying the bag, having this one above the welding line (2) a handle (4) for the manual transport thereof.

[0012] Now then, the novelty of the bag (1), is that the opening (3) which is originated in the upper part of the bag (1), is extended forming a long tubular neck (5), with a sufficient length that successively allows the folding several times, in order to form or configure a folding (6), which will remain inside a cap (7) that is an integral part of the body of the bag (1) itself and is linked to it through a tie (8), whereby this cap (7) and the tie (8) itself, are permanently linked to the bag and can be obtained in the same shape thereof, that is of the bag.

[0013] As it can be verified, the closing device thus obtained is totally efficient, since the folding (6) of the neck (5) by successive foldings, hinders any discharge of the liquid contained in the bag (1), with the peculiarity that such folding (6) of the neck (5), remains in its position when tightly placed in the inside of the cap (7) itself, being necessary to manually pull up this one to detach it from that folding (6) and be able to carry out the unfolding thereof and, as consequence, the stretching up of the neck (5) in order to allow the discharge of the liquid contained in the bag.

[0014] Although the container represented in the attached drawings, is formed in a bag shape, as it can be understood it can adopt any shape and be intended for containing liquid or semiliquid products, dusty ones or any granular type of products, even of gaseous nature, since the closing device obtained can offer a total sealing.

Claims

1. Intrinsic closing device for a flexible wall container, preferably of plastic material and provided with a discharge opening, characterized in that it is formed by a long tubular neck (5) and by a retention cap (7), which tubular neck (5) starts up from the opening as extension of the wall of the container or bag (1) and it is successively folded several times (6) in transversal direction, forming a folding (6) which hinders the discharge of the container content, and which cap (7) is dimensioned in order to tightly receive the tubular neck (5) in folded position, being the mentioned cap (7) linked to the container or bag (1) through a tie (8) preferably obtained together with the cap (7) in the same forming phase of the container, as an integral part of the wall of the bag or container (1).
