En la actualidad, los colchones de agua están disponibles comercialmente para su uso en la vida diaria,ycuando un colchón de agua se extiende sobre una cama, un sofá, o los semejantes, él no sólo proporciona confort, sino que también actúa como una herramienta de terapia física. Dicho colchón de agua tiene generalmente una cavidad sellada herméticamente constituida por dos capas de un material de película,y dentro de la cavidad, se inyecta agua para formarun colchóndeagua.Enalgunosdeloscolchonesdeaguaconvencionales,se instalaun calentadororefrigerador en la cavidad para calentar o enfriar el agua para proporcionar una compresa fría o caliente. Los ejemplos incluyen un colchón de agua caliente superconductora según se describe en el Documento dePatente 1. Sin embargo, cuando está en servicio, el colchón de agua se puede romper completamente, siendo perforado mediante un material en punta, At present, water mattresses are commercially available for use in daily life, and when a water mattress is spread over a bed, a sofa, or the like, it not only provides comfort, but also acts as a tool of physical therapy. Said water mattress generally has a hermetically sealed cavity consisting of two layers of a film material, and within the cavity, water is injected to form a water mattress. Some of the conventional water mattresses, a cooler heater is installed in the cavity to heat or cool the water to provide a water cold or hot compress. Examples include a superconducting hot water mattress as described in Patent Document 1. However, when in service, the water mattress can be completely broken, being perforated by a pointed material,

o se abre por reventón, siendo deprimido con una gran presión, lo que da lugar a la fuga de la cavidad, lo que hace inservible el colchón de agua, con lo que el colchón de agua generalmente tiene una vida de servicio corta. Además, debidoala capacidadde ﬂujo del agua,el colchónde agua tiene una estabilidad ligeramente mala,yproporciona una sensación de incomodidad por su oscilación. or it opens by blowout, being depressed with great pressure, which results in the leakage of the cavity, which makes the water mattress unusable, so that the water mattress generally has a short service life. In addition, due to the water ﬂ ow capacity, the water mattress has a slightly poor stability, and provides a feeling of discomfort from its oscillation.

Efectos ventajosos de la invención Advantageous effects of the invention

El método antes mencionado para lafabricación de un colchón de gel adopta un gel en lugar de agua, la cual se usa convencionalmente, para producir un colchón de gel en copos las superﬁcies externas del cual están dentro de una bolsa; el gel es un coloide obtenido mediante polimerización de la materia orgánica; aproximadamente 70% del gel está constituidopor agua;yasíel colchóndegel tiene una capacidad térmicaelevada próximaaladel agua,Porlo tanto,aligualqueel colchónde agua,el colchóndegel tieneun comportamiento endotérmicoextremadamentebueno. Además, el gel no ofrece una capacidad de ﬂujo como el agua, siendo capaz de ser usado de manera estable, e incluso cuando la bolsa se rompe totalmente mediante un material en punta o se revienta para ser agujereado, no dará lugar a fugas,lo que permite quela vidade servicio del colchón se prolongue sustancialmente.El métododefabricación usa la reacción de polimerización; suaviza el colchón de gel plano dentro de la bolsa mediante la aplicación de una presión externa;yasísepuede proporcionarun colchóndegel acabadoquetienelas superﬁciesexterioressuavesypulcras. The aforementioned method for the manufacture of a gel mattress adopts a gel instead of water, which is conventionally used, to produce a gel mattress in flakes the outer surfaces of which are inside a bag; The gel is a colloid obtained by polymerization of organic matter; Approximately 70% of the gel is made up of water, and thus the mattress has a high thermal capacity close to that of the water, therefore, just like the mattress with water, the mattress has an endothermic behavior extremely well. In addition, the gel does not offer a flow capacity like water, being able to be used stably, and even when the bag is totally broken by a pointed material or busted to be pierced, it will not lead to leaks, which allows the service life of the mattress to be substantially extended. The manufacturing method uses the polymerization reaction; It softens the flat gel mattress inside the bag by applying external pressure; and it can also provide a finished mattress that has the surface under the surface and is soft.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement

The object of the patent is a mattress of gel flakes as well as its manufacturing method.

Document D01 discloses a gel mattress where the upper and lower layers of polyethylene are joined at their three sides to form a bag leaving the room open where the highly absorbent polymer mixture with gel-shaped water is introduced (see summary ).

Document D02 discloses a method of obtaining gel flakes of acrylic polymers and polyamides from a sheet

or gel block, so that said flakes do not agglomerate during storage (see column 1, lines 10-35; column 2, lines 15 and 23).

Document D03 discloses a method of manufacturing a mattress with gel bands where the gel in liquid form is cast in the space provided for it and is cured obtaining a solid, soft and elastic material (see paragraphs 5, 6, 9 and 12).

None of the documents D01-D03 cited or any relevant combination thereof discloses a mattress of gel flakes where said flakes are formed in situ by pouring into a sealed bag of a solution in monomer water, a crosslinking agent and a initiator.

Therefore, it is considered that the invention set forth in claims 1-20 meets the requirements of novelty and inventive activity, as set forth in Articles 6.1 and 8.1 of the Patent Law.
