DESCRIPCIÓN DESCRIPTION
Elemento de embalaje para artículos diversos y método para su realización. OBJETO DE LA INVENCIÓNPackaging element for miscellaneous items and method for its realization. OBJECT OF THE INVENTION
La presente invención tiene por objeto un elemento de embalaje para artículos diversos y método para su realización.The present invention has as its object a packaging element for various articles and method for its realization.
CAMPO DE LA INVENCIÓN Para el embalaje de diversos objetos como sanitarios, tal como bañeras, muebles de todo tipo, partes de automóviles, como puertas, etc., se utilizan en general materiales laminares para su protección durante el embalaje, transporte y almacenamiento.FIELD OF THE INVENTION For the packaging of various objects such as sanitary ware, such as bathtubs, furniture of all kinds, car parts, such as doors, etc., laminar materials are generally used for protection during packaging, transport and storage.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Los materiales laminares empleados en el embalaje de diversos tipos de objetos, consisten en materiales laminares del tipo de cartón ondulado y de plástico, el cual puede ser de material laminar muy fino expandido de densidad alta que resulta muy duro. Estos tipos de embalaje presentan el inconveniente de que no proporcionan la protección deseada, en el propio embalado, en el transporte del objeto, y en su almacenamiento.The sheet materials used in the packaging of various types of objects, consist of sheet materials of the type of corrugated cardboard and plastic, which can be of very thin expanded sheet material of high density that is very hard. These types of packaging have the disadvantage that they do not provide the desired protection, in the packaging itself, in the transport of the object, and in its storage.
Asi, el cartón ondulado se rompe fácilmente cuando se dobla, y ello ocurre precisamente en los puntos o lugares donde se desea la mejor protección del objeto en cuestión. En cuanto a los materiales plásticos, si son muy finos no protegen adecuadamente los golpes, y los muy duros dejan espacios vacios y en otro orden no protegen para golpes determinados y según la dirección de los mismos. SUMARIO DE LA INVENCIÓNThus, the corrugated cardboard easily breaks when it is folded, and this occurs precisely at the points or places where the best protection of the object in question is desired. As for the plastic materials, if they are very thin they do not adequately protect the blows, and the very hard ones leave empty spaces and In another order, they do not protect against specific blows and according to their direction.
