OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

La presente invención se refiere a un cortador de film plástico con la cuchilla oculta para uso 5 doméstico y que es transportable para su uso. The present invention relates to a plastic film cutter with the hidden blade for domestic use and which is transportable for use.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Son conocidos en la actualidad varios dispensadores y cortadores de film plástico, algunos de ellos en pared o muebles, como por ejemplo los modelos: ES-1013248, ES-1053215, ES-10 1057925, ES-1071848 pero tienen la desventaja de que hay que transportar el film plástico desde el cortador hasta los alimentos que se desean tapar o cubrir, con lo que supone que el film plástico se puede arrugar, se pegue entre sí mismo y hace más difícil su uso y aprovechamiento. También existen otros cortadores transportables como por ejemplo el que traen las cajas suministradoras del film plástico. 15 Several plastic film dispensers and cutters are known today, some of them on wall or furniture, such as the models: ES-1013248, ES-1053215, ES-10 1057925, ES-1071848 but they have the disadvantage that there are that transport the plastic film from the cutter to the food that you want to cover or cover, which means that the plastic film can wrinkle, stick together and make it more difficult to use and use. There are also other portable cutters such as the one that bring the plastic film supply boxes. fifteen

Por otra parte los cortadores móviles, cuando se guardan en cajones con otros utensilios, las propias cuchillas pueden rayar y perder vida útil del cortador. On the other hand, mobile cutters, when stored in drawers with other utensils, the blades themselves can scratch and lose the life of the cutter.

Con la presente invención se pretende realizar un cortador de film plástico con la cuchilla oculta 20 para uso doméstico, y que resuelva de forma eficiente las necesidades de realizar un corte limpio, dejando el mismo film plástico listo para el siguiente uso, sin arrugas y garantizando la máxima seguridad. With the present invention it is intended to make a plastic film cutter with the hidden blade 20 for domestic use, and efficiently solve the needs of making a clean cut, leaving the same plastic film ready for the next use, without wrinkles and guaranteeing Maximum security

DESCRIPCIÓN 25 DESCRIPTION 25

La presente invención se refiere a un cortador de film plástico con la cuchilla oculta para uso doméstico. The present invention relates to a plastic film cutter with the hidden blade for domestic use.

Este cortador de film plástico este construido sobre una carcasa en forma rectangular plana, continuada de un semicírculo. 30 This plastic film cutter is built on a flat rectangular housing, continued from a semicircle. 30

Dentro del semicírculo de la carcasa, se aloja el rollo de film plástico que para su uso, sale por la abertura del semicírculo, estando siempre perfectamente visible y practicable para su uso. Inside the semicircle of the housing, the roll of plastic film is housed, which for its use, exits through the opening of the semicircle, being always perfectly visible and practicable for its use.

El rollo de film plástico alojado dentro del semicírculo, se le coloca un eje en su interior que 35 está provisto en un extremo de un cono fijo y en el otro extremo Ileva un cono con rosca, con el que se aprieta el rollo del film plástico, de esta forma podemos colocar todos los rollos de film plástico con pequeñas variaciones tanto en la largura como en diámetro interior del rollo de film plástico (adaptándose a las distintas medidas de los fabricantes de film plástico). The roll of plastic film housed inside the semicircle, an axis is placed inside it that is provided at one end of a fixed cone and at the other end it carries a threaded cone, with which the roll of the plastic film is pressed , in this way we can place all the rolls of plastic film with small variations both in the length and in internal diameter of the roll of plastic film (adapting to the different measures of the manufacturers of plastic film).

Dicho eje que sujeta el rollo de film plástico y que se aloja dentro del semicírculo, se sujeta a la carcasa con dos tapas en los extremos, una fija y otra con rosca para poder cambiar el rollo de film plástico. Estas tapas Ilevan en su interior un orificio un poco superior al diámetro del eje para que pueda este girar libremente. Said shaft that holds the roll of plastic film and that is housed inside the semicircle, is fastened to the housing with two end caps, one fixed and the other with a thread to be able to change the roll of plastic film. These covers have a hole in their interior slightly larger than the shaft diameter so that it can rotate freely.

En la parte rectangular plana de la carcasa y bajo la tapa de mecanismo, se aloja el seguro con su muelle de recuperación que bloquea la cuchilla hasta que se tensa el film, la cuchilla con su batón de empuje, su muelle de recuperación y las guías que hacen que la cuchilla salga de una manera determinada y especifica garantizando el corte del film plástico. In the flat rectangular part of the housing and under the mechanism cover, the safety is housed with its recovery spring that locks the blade until the film is tensioned, the blade with its thrust pad, its recovery spring and the guides that make the blade come out in a specific and specific way guaranteeing the cutting of the plastic film.

Conociendo que el film plástico a pesar de su apariencia frágil, tiene bastante resistencia y elasticidad al corte, y mucho más cuando se intenta cortar todo a la vez. Se ha optado por la siguiente solución: colocar unas guías en la cuchilla para que se deslice sobre las mismas de la siguiente manera. Cuando se presiona sobre el botón empujador de la cuchilla, esta sale de un extremo y avanza hacia el mismo comenzando a cortar y sin dejar de avanzar va saliendo del 5 otro extremo hasta terminar el corte de forma suave y rápida. Knowing that the plastic film despite its fragile appearance, has enough resistance and elasticity to the cut, and much more when trying to cut everything at once. We have opted for the following solution: place guides on the blade so that it slides over them as follows. When pressed on the pusher button of the blade, it comes out of one end and advances towards the same beginning to cut and while continuing to advance it leaves the other end until it finishes cutting smoothly and quickly.

Las guías en este diseño se han colocado sobre las cuchillas pudiendo ser colocadas en la carcasa sin perder ninguna funcionalidad. The guides in this design have been placed on the blades and can be placed in the housing without losing any functionality.

The object of the invention is to achieve a plastic film cutter with the hidden blade so that it can be stored in the drawers, the blade being hidden, so that it does not deteriorate, does not scratch 25 other utensils and thus be able to prolong the life of the blade .

Otro de los objetivos que se consiguen con este utensilio, es que el cortador al ser transportable, puede cortarse el film plástico sobre los alimentos y envases que se deseen cubrir, o sobre una superficie pare colocar los alimentos encima y envolverlos, ya que este 30 cortador tiene la peculiaridad de que al no tener que hacer esfuerzo ni movimientos hacia ningún lado para cortar el envoltorio plástico, deja el mismo plástico liso pan su uso sin las arrugas que este produce cuando se mueve de un sitio a otro pegándose entre el mismo, hasta hacerlo en alguna ocasión poco servible. Permite cortar desde pequeñas hasta largas porciones de envoltorio plástico. La abertura de salida, es suficientemente amplia pan poder 35 acceder al mismo, y siendo el eje adaptable a las distintas medidas de los fabricantes de rollos de envoltorios plásticos. Another of the objectives achieved with this utensil is that the cutter, being transportable, can cut the plastic film on the food and packaging that you wish to cover, or on a surface to place the food on top and wrap it, since it is 30 Cutter has the peculiarity that by not having to make any effort or movements to any side to cut the plastic wrap, the same smooth plastic leaves its use without the wrinkles that it produces when moving from one place to another by sticking between it, until doing it in some occasion little useable. It allows to cut from small to long portions of plastic wrap. The exit opening is wide enough to be able to access it, and the axis being adaptable to the different sizes of the manufacturers of plastic wrap rolls.
