La presente solicitud se enmarca dentro del sector de los y procedimientos para la fabricación de cajas o bandejas con un recubrimiento impermeable. The present application is framed within the sector of and procedures for the manufacture of boxes or trays with a waterproof coating.
El documento más cercano es la Patente Española nº 9002815. En dicha patente se mejora la productividad en la fabricación de un film con termoadhesivo para su pegado en un recipiente. The closest document is Spanish Patent No. 9002815. In said patent, productivity is improved in the manufacture of a film with thermo-adhesive for bonding in a container.
El problema del documento más cercano es que para engancharse a un recipiente, el film debe precalentarse, las propiedades del adhesivo se cambian y entonces se produce el pegado. Ello lleva a que si se cambia el recipiente, se tiene que tener mucho cuidado con el adhesivo, ya que al fabricarlo debe tener la capacidad de poder engancharse a un papel siliconado y al retirarse no perder propiedades y al propio tiempo que cuando se fusionan no cambien las propiedades. Unos pequeños cambios en la presión o la temperatura (por ejemplo en un día de mucho frío o mucho calor) puede obligar a realizar muchos reajustes. The problem of the closest document is that to be hooked to a container, the film must be preheated, the properties of the adhesive are changed and then the bonding occurs. This leads to the fact that if the container is changed, you have to be very careful with the adhesive, since when manufacturing it you must have the ability to be able to hook it to a siliconized paper and when withdrawing do not lose properties and at the same time that when they merge Change the properties. Small changes in pressure or temperature (for example on a very cold or very hot day) can force many adjustments.
Así, el inventor ha desarrollado un procedimiento que lo que pretende es olvidarse de todos los ajustes y ahorrarse el coste del papel siliconado. Thus, the inventor has developed a procedure that is intended to forget all the adjustments and save the cost of silicone paper.
De este modo, el inventor ha situado la fase de encolado del material impermeable, un film habitualmente, en una fase anterior al pegado. Es decir, la bobina con el film no viene con el adhesivo, con lo que pesa menos. In this way, the inventor has placed the glueing phase of the impermeable material, a film usually, in a phase prior to bonding. That is, the coil with the film does not come with the adhesive, which weighs less.
Así, se consigue que empleando una cola autoadhesiva no sea preciso emplear calor para su pegado. Posteriormente se podrá empelar calor pero será para adaptar el film, pero no para pegar porque el film ya estará pegado al recipiente. Thus, it is achieved that using a self-adhesive glue it is not necessary to use heat for bonding. Later heat may be used but it will be to adapt the film, but not to paste because the film will already be glued to the container.
Es un objeto de la presente invención un procedimiento para la impermeabilización de recipientes del tipo que comprende: una primera fase en la que se pone en funcionamiento un alimentador de material impermeable laminado en continuo, definiendo una primera cara que se unirá después sobre el recipiente y una segunda cara en contacto con el producto que contiene el recipiente, caracterizado porque comprende: una segunda fase en la que se dispone una cola autoadhesiva sobre la primera cara, una tercera fase en la que se sitúa el material impermeable con la primera cara con cola autoadhesiva sobre el lado del recipiente a cubrir, y una cuarta fase en la que se adhiere la cola autoadhesiva de la primera capa al recipiente, uniéndose. An object of the present invention is a process for the waterproofing of containers of the type comprising: a first phase in which a feeder of continuous laminated impermeable material is put into operation, defining a first face that will then be joined on the container and a second face in contact with the product containing the container, characterized in that it comprises: a second phase in which a self-adhesive glue is arranged on the first face, a third phase in which the impermeable material is placed with the first face with glue self-adhesive on the side of the container to be covered, and a fourth phase in which the self-adhesive glue of the first layer adheres to the container, joining.
De este modo, en una concreta realización, el procedimiento objeto de la presente patente se podría configurar con un alimentador de material impermeable, laminado, o en forma de lámina, en continuo, por ejemplo una bobina con un film enrollado. Thus, in a specific embodiment, the process object of the present patent could be configured with a feeder of impermeable, laminated, or sheet-shaped material, in continuous, for example a coil with a rolled film.
Dicho film tiene dos caras, una primera que será donde se impregnará de cola autoadhesiva y una segunda que será la que estará posteriormente en contacto con el producto que contendrá el recipiente. Al ponerse en funcionamiento la bobina, en la primera fase, el film se desenrollará. This film has two faces, a first one that will be impregnated with a self-adhesive glue and a second one that will be the one that will subsequently be in contact with the product that the container will contain. When the coil is put into operation, in the first phase, the film will be unwound.
En la segunda fase se dispone o impregna una cola autoadhesiva sobre la primera cara. Ello se puede hacer de diferentes formas, por ejemplo, mediante un rodillo impregnador con una rasqueta que limita el grosor de la capa de autoadhesivo, por pulverización, mediante un labio laminador, etc.,. In the second phase a self-adhesive glue is arranged or impregnated on the first face. This can be done in different ways, for example, by means of an impregnating roller with a scraper that limits the thickness of the self-adhesive layer, by spraying, by means of a laminating lip, etc.,.
En la tercera fase se sitúa el material impermeable o film con la primera cara con cola autoadhesiva sobre el lado del recipiente a cubrir, es decir, encarado o enfrentado con la zona del recipiente a cubrir. In the third phase, the waterproof material or film with the first face with a self-adhesive glue is placed on the side of the container to be covered, that is, facing or facing the area of the container to be covered.
Posteriormente, en la cuarta fase se adhiere la cola autoadhesiva de la primera capa al recipiente, quedando entonces la primera capa unida al recipiente. Dicha adhesión se puede hacer mediante presión, sin necesidad de emplear temperatura. Subsequently, in the fourth phase the self-adhesive glue of the first layer is adhered to the container, the first layer being then attached to the container. Such adhesion can be done by pressure, without using temperature.
Si luego se precisase que el recipiente disponga de una forma concreta, se podrá aplicar temperatura para dilatar el film, pero no para pegar, ya que el film está pegado al recipiente. If it is later required that the container has a specific shape, temperature may be applied to dilate the film, but not to stick, since the film is glued to the container.
Si fuese preciso introducir signos o caracteres, ése podrían introducir en una fase intermedia, previa a la segunda fase, en la que se imprime sobre la primera cara unos caracteres o signos para ser visibles desde la segunda cara en caso de ser el film transparente. If it were necessary to introduce signs or characters, they could be introduced in an intermediate phase, prior to the second phase, in which characters or signs are printed on the first face to be visible from the second face in case of being the transparent film.
El recipiente podría estar fabricado en un material poroso, por ejemplo en un cartón, pudiendo entonces configurarse de tal manera que el material impermeable se separa del recipiente para poder reciclarse ambos materiales. The container could be made of a porous material, for example in a cardboard, and can then be configured such that the impermeable material is separated from the container so that both materials can be recycled.
El inventor ha calculado que el coste de fabricación de un recipiente según los sistemas que se emplean hoy en día, al coste de fabricación según la presente invención, supone un ahorro de más de un 20% en el costo del recipiente, sin tener en cuenta ni el ahorro del papel siliconado (que de acuerdo con esta invención no se emplea) ni el ahorro de tiempo de los operarios que lo ponen en funcionamiento. The inventor has calculated that the cost of manufacturing a container according to the systems used today, at the cost of manufacturing according to the present invention, represents a saving of more than 20% in the cost of the container, without taking into account neither the saving of the siliconized paper (which according to this invention is not used) nor the saving of time of the operators who put it into operation.
La presente patente de invención describe un nuevo procedimiento para la impermeabilización de recipientes. Los ejemplos aquí mencionados no son limitativos de la presente invención, por ello podrá tener distintas aplicaciones y/o adaptaciones, todas ellas dentro del alcance de las siguientes reivindicaciones. The present invention patent describes a new process for waterproofing containers.
