Description

ADDITION TO DISPENSE THE LIQUID CONTAINED IN A BAG FIELD OF THE INVENTION The present invention is related to the packaging industry, and more specifically, with the possibility of distributing certain liquid items, food and cleaners to each other, in plastic bags, and allowing to conveniently serve the use thereof. liquid contained in said bag.

BACKGROUND OF THE INVENTION The production process of filling liquids in bags consists of a series of operations in which the bags are formed simultaneously with the filling of the same. The sheet from which the bag is to be formed is fed, from a roll, into the external upper part of a nozzle. The liquid to be bagged circulates inside this nozzle. When the sheet is fed, it surrounds the nozzle and, continuously, it is sealed longitudinally to transform the sheet into a tube. The tube is continuously moving down and another means of seal, seals and cuts the end of what will be a bag, the liquid is deposited in the interior of the tube that even by the weight of the liquid itself moves down , and then another transversal seal is formed that ends up forming the bag already with the liquid inside it.

This method of filling and forming bags makes the operation quite fast and economical, with a series of additional advantages.

Currently, to facilitate the serving of content, plastic bags containing liquids inside have a valve or any other element integrated or fused to its outer or inner walls, either by means of heat or ultrasound.

This conformation of bags prevents the plastic film from being delivered to the bottler in roll form to manufacture the bags, folding, sealing and filling with liquid in a continuous way, having to form and fill the bag with liquid individually, making the process Manufacturing slower and more expensive accordingly.

A means that allows the bag to be formed simultaneously with the filling and that at the same time allows to be able to serve the content easily and quickly, means a technological advance that will give the possessor of this means an important competitive advantage.

OBJECTIVES OF THE INVENTION One of the objectives of the present invention is to provide certain liquid bagged products, the possibility of being served easily and quickly.

Other objectives of the present invention is to make the packaging interesting in bags, to liquids that are currently distributed in another way of packaging.

Still another objective of the present invention is to make possible the packing processes of certain liquids already packaged in bags with a server system, in a cheaper and more automatic way, Still another objective of the present invention is to provide the market with packaging alternatives that are cheaper and have most of the advantages of current packaging.

Another objective of the present invention is to achieve an add-on that allows multiple reuse of at least the dispenser.

Other objects and advantages of the present invention may be apparent from the study of the following description and the accompanying drawings for illustrative purposes only and not limitation.

DETAILED DESCRIPTION OF THE INVENTION In FIG. 1 In this figure we see the bag for liquids formed with plastic film (1), which has been integrated a plastic copy (2) with application of heat and that goes through the inside of the plastic film, before filling it with liquid , to extract and dose the liquid contained in it.

In FIG. 2 In this figure we see the liquid bag formed with plastic film (1), which has been punctured and a valve (3) has been integrated with heat before filling it with liquid, to extract and dose the liquid contained in it.

In FIG. 3 A section of the independent device is seen that serves to guide a dispensing valve, consisting of a body (4) hollowed inside (5), the shoulder of fixation (6) which has adhesive on its back face (7) and a detachable liner (8) to protect the adhesive.

In FIG. 4 A front view of the independent device is shown which serves to guide a dispensing valve where the outer wall of the body (4) is seen, the inner wall (5) the shoulder (6) and the flange of the removable lainer (8) that protects the adhesive.

In FIG. 5 We observe a cut of the dispensing valve where we see the cutting end (10) the cavities that allow the passage of the liquid (16), the body of the valve (11) and the shoulder (9) that allows the valve to stop .

In FIG. 6 A rear view of the device in which the body (4) is shown is the fixing shoulder (6) with its adhesive on the back (7) and the protective lacer (8) being removed.

In FIG. 7 In this figure we see a front view of the device, which shows us an alternative with a circular shoulder (6) In FIG. 8 It is shown how the independent device that serves to guide a dispensing valve (14) has been stuck firmly (15) by means of the shoulder (6) with adhesive, to the outer wall of the bag with liquid (12) In FIG. 9 It is shown how the dispensing valve (11) has been pushed inside the independent device (14) and has been stopped by the stop of the valve (9) that has hit the end of the device while breaking the plastic film (17). ) of the bag with liquid (13), thus allowing the passage of the liquid (13) through the cavities (16) to the inside of the valve (11) to allow its dosing. Once the bag is empty, the valve (11) is removed and the bag with the device attached to it is discarded, again using the valve (11) in a new sealed bag, filled with liquid and with a new device, repeating the steps previous, In FIG. The plastic bag (1) with liquid inside it is shown with the device (14) adhered to its outer wall (12) and the dispensing valve (11) placed inside the tank (14), piercing the outer wall (12) of the bag, to dispense the liquid (13) contained therein.

In FIG. 11 Another alternative is seen in which the device (14) has integrated a punch (10) at one end with openings (16) that allow the passage of the liquid contained in any bag, and where the shoulder is observed ( 6) with an adhesive on one of its sides (7) which will adhere firmly to the outer wall (12) of the bag and to which a dosing device (18) is fitted on the other end which can be attached by half of a thread (19). In another embodiment not illustrated, the connection between the device (14) and dispenser (18) may be carried out by pressure or by any other mechanical means.

In FIG. 12 We observe the same alternative as in the previous figure but with a dispensing valve (11) which can be coupled by means of a thread (19), under pressure or by any other mechanical means.

In FIG. 13 The device (14) is shown with its dispense valve (11) coupled in an illustrative but non-limiting manner by means of a thread (19) to prevent the liquid (13) contained inside the bag from coming off when the punch (10) of the device (14) is inserted through the outer wall (12) of the bag, and the shoulder of the device (6) is fixed by means of the adhesive placed on its face (7), against the wall outside (12) of the bag with liquid.

In FIG. 14 We observe the operation of this alternative which consists in pre-illustrating but not limiting a dispensing valve (11) to one end of the device (14) and puncturing the outer wall (12) of the bag, fixing it by means of a adhesive (7) placed on the shoulder (6) of the device (14) and thus allow to dispense its contents in a safe and effective way, once the bag is emptied the dispense valve (11) of the device (14) is disconnected discarding the bag (1) with the device (14) adhered to its outer wall (12) by reusing the dispenser or the dispensing valve, with a new bag and a new device.

From the analysis of these figures, it is clear that the elements forming the implement object of the present invention fulfill three functions, one of which is to allow the attachment to the bag to prevent displacement of the dispenser once installed. The other is the seal at the level of the hole generated by the penetration. Another function is to make possible the penetration of the wall of the bag and finally the function of exit control to allow or prevent the exit of the liquid.

In order to carry out these functions, it is then necessary, and is one of the modalities of the present invention, to associate a copy with peripheral shoulders comprising an adhesive. A pointed spike that penetrates the wall of the bag and finally the dispenser.

For reasons of economy, the copy and even the spike can be made disposable, but making the dispenser disposable would be an expensive waste. Therefore, at least one of the embodiments of the invention should have the possibility of separating the dispensing element from the rest of the attachment.

This is achieved by means of threaded or coupled elements of the uncoupling type.

Then, in one of the embodiments of the present invention the attachment consists of the association of a copy with peripheral shoulders with adhesive on the face with which it will be fixed to the outer face of the wall of the bag, said copy will allow a tang pointed hollow, with the opposite end to the open tip, with the possibility of allowing liquid to enter the lower space of the same, slide inside it, tightly creating a seal between the outer face of the spike and the inner surface of copy. At the opposite end to the tip the tang has the possibility of being coupled with a dispensing element. The coupling means, in one of the modes consists of an internal thread and an external thread.

In this embodiment, the copy is adhered to the bag at the point where the liquid is intended to be served, subsequently, the dispenser is attached to the pin and the dispenser is placed in the closed position, then the pin is slid with the pointed end pointed to the bag, inside the copy until the tip has completely entered the bag.

Different modalities of the attachment have been tested and it has been found, for example, that a possible option is to confer on the spike the functions of fixation, sealing and puncture, providing peripheral shoulders to said spike or punch, with an adhesive in a of the faces of said shoulders.

This modality would have the disadvantage of having to carry out the puncture very quickly to avoid that the liquid contained in the bag prevents the subsequent adhesion. However, it is an economic modality.

The invention has been described sufficiently so that a person with average skill in the art can reproduce and obtain the results mentioned in the present invention. However, any person skilled in the art who is competent in the present invention may be able to make modifications not described in the present application, however, if for the application of these modifications in a certain structure or in the manufacturing process thereof, the subject matter claimed in the following claims is required, said structures should be understood within the scope of the invention.
