Description

DESCRIPCIÓN  DESCRIPTION
CINTA PARA ASAS DE BOLSAS DE PAPEL. Objeto de la invención TAPE HANDLE FOR PAPER BAGS. Object of the invention
La presente invención se refiere a una cinta para asas de bolsas de papel, del tipo de las que comprenden una tira plana y alargada, en continuo, conformada por al menos una lámina de papel y que presentan unas porciones extremas para su fijación a una bolsa de papel. The present invention relates to a tape for handles of paper bags, of the type comprising a flat and elongated strip, continuously formed of at least one sheet of paper and having end portions for attachment to a bag of paper.
Campo de aplicación de la invención. Field of application of the invention.
Esta invención es aplicable en la fabricación de asas para bolsas de papel.  This invention is applicable in the manufacture of handles for paper bags.
Antecedentes de la invención. Background of the invention.
Actualmente existe una tendencia generalizada de reducción o eliminación de las bolsas de plástico, ampliamente utilizadas en supermercados para el transporte de la compra. Una alternativa más adecuada desde un punto de vista ecológico es la sustitución de las bolsas de plástico por bolsas conformadas íntegramente en papel, ya que esto permite su posterior reciclado. Sin embargo, estas bolsas deben de cumplir unos requerimientos de resistencia por el uso al que van destinadas y soportar un peso aproximadamente unos 10 Kg.  Currently there is a general tendency to reduce or eliminate plastic bags, widely used in supermarkets to transport the purchase. A more suitable alternative from an ecological point of view is the replacement of plastic bags with bags made entirely of paper, since this allows subsequent recycling. However, these bags must meet resistance requirements for the use they are intended for and bear a weight of approximately 10 kg.
Por tanto, uno de los inconvenientes principales de fabricación de estas bolsas es dotarlas de unas asas que puedan soportar el peso mencionado y cuya resistencia no se vea mermada en unas condiciones normales de uso; por ejemplo, al humedecerse por la sudoración de las manos o por la existencia de una humedad ambiental muy elevada.  Therefore, one of the main drawbacks of manufacturing these bags is to provide them with handles that can withstand the mentioned weight and whose resistance is not diminished under normal conditions of use; for example, when moistened by the perspiration of the hands or by the existence of a very high humidity.
En estas condiciones desfavorables la utilización de un asa constituida simplemente por una tira de papel no impide la rotura de las asas cuando se aplica a la bolsa una carga de unos 10 Kg. que es lo aconsejable para su uso en bolsas de supermercados. Under these unfavorable conditions the use of a handle consisting simply of a strip of paper does not prevent the breakage of the handles when a load of about 10 kg is applied to the bag, which is advisable For use in grocery bags.
En este sentido es de destacar también la existencia del documento WO2010063851 A1 , del mismo titular, referente a una cinta ecológica reforzada aplicable, entre otros usos, a la fabricación de asas para bolsas preconfiguradas.  In this regard it is also worth noting the existence of document WO2010063851 A1, of the same owner, referring to a reinforced ecological tape applicable, among other uses, to the manufacture of handles for preconfigured bags.
Esta cinta ecológica reforzada está constituida en su totalidad en papel con el fin de facilitar su reciclado. Dicha cinta ecológica reforzada está constituida a partir de, al menos, una lámina de papel y comprende un elemento tubular plano que incorpora interiormente dos o más cordones o tiras de papel dispuestos paralelamente en dirección longitudinal y unidos con el elemento tubular por una franja de adhesivo.  This reinforced ecological tape is made entirely of paper in order to facilitate recycling. Said reinforced ecological tape is constituted from at least one sheet of paper and comprises a flat tubular element that internally incorporates two or more paper cords or strips arranged parallel in longitudinal direction and connected with the tubular element by a strip of adhesive .
Esta estructura de la cinta ecológica reforzada, resulta especialmente idónea para la conformación de asas de bolsas de papel que deban de soportar un peso importante pero hacen que económicamente sean inviables en casos de consumos masivos de bolsas pues esta conformada por dos cordones o tiras de papel.  This structure of the reinforced ecological tape, is especially suitable for shaping paper bag handles that must bear an important weight but make them economically unfeasible in cases of mass consumption of bags because it is made up of two cords or strips of paper .
Descripción de la invención Description of the invention
La cinta para asas de bolsas de papel objeto de esta invención es del tipo de las que comprenden una tira plana y alargada, conformada por al menos una lámina de papel.  The tape for handles of paper bags object of this invention is of the type comprising a flat and elongated strip, formed by at least one sheet of paper.
Esta cinta para asas presenta unas características orientadas a permitir su conformación mayoritariamente en papel combinando este material con un material flexible y resistente o por otra tira de celulosa más estrecha que garantice la integridad del asa cuando se somete a una carga importante y en condiciones desfavorables por ejemplo de humedad.  This tape for handles has characteristics oriented to allow its conformation mostly on paper by combining this material with a flexible and resistant material or by another narrower cellulose strip that guarantees the integrity of the handle when subjected to an important load and in unfavorable conditions. humidity example.
Otro de los objetivos de la invención es posibilitar la separación de los materiales de diferente naturaleza constitutivos de la cinta para asas de forma que puedan ser reciclados por separado una vez utilizada y desechada la bolsa.  Another objective of the invention is to enable the separation of materials of different nature constituting the handle tape so that they can be recycled separately once the bag is used and discarded.
Otro de los objetivos de la invención es la incorporación del mencionado elemento de seguridad en la cinta para asas de forma que ésta mantenga un adecuado confort de uso, consiguiendo un reparto superficial de la presión sobre las manos del usuario. Another object of the invention is the incorporation of said security element in the belt for handles so that it maintain adequate comfort of use, achieving a superficial distribution of pressure on the user's hands.
Para ello, y de acuerdo con la invención, la cinta para asas comprende un elemento de seguridad, de polímero o de celulosa, a modo de cinta o de hilo, flexible y resistente. Dicho elemento de seguridad tiene un ancho menor que la tira plana y está dispuesto longitudinalmente en posición centrada entre dos capas de papel constitutivas de dos caras exteriores opuestas de la tira plana de papel.  For this, and according to the invention, the handle tape comprises a security element, made of polymer or cellulose, as a tape or wire, flexible and resistant. Said security element has a width smaller than the flat strip and is arranged longitudinally in a centered position between two layers of paper constituting two opposite outer faces of the flat paper strip.
La incorporación de este elemento de seguridad, de polímero o celulosa, en la cinta para asas impide la rotura del asa y consiguientemente la caída de la bolsa aunque la tira plana conformada en papel se haya humedecido por cualquier causa.  The incorporation of this security element, of polymer or cellulose, in the handle tape prevents the breakage of the handle and consequently the fall of the bag although the flat strip formed on paper has been dampened for any reason.
La disposición longitudinal y en posición centrada del elemento de seguridad respecto a la tira plana de papel garantiza que los bordes longitudinales del asa estén conformados únicamente en papel proporcionando un mayor confort de uso al deformarse dichos bordes en caso que se produzca una presión excesiva debido al peso de la carga soportada.  The longitudinal and centered position of the safety element with respect to the flat strip of paper ensures that the longitudinal edges of the handle are formed only in paper providing greater comfort of use when said edges deform in case of excessive pressure due to the Load weight supported.
La utilización del elemento de seguridad con una configuración aplanada, a modo de cinta, proporciona un reparto superficial, y no puntual o lineal, de la carga sobre la mano del usuario proporcionando un mayor confort de uso.  The use of the security element with a flattened configuration, as a tape, provides a superficial, and not punctual or linear, distribution of the load on the user's hand providing greater comfort of use.
De acuerdo con la invención las capas de papel conformantes de la tira plana están fijadas entre sí, forma continua o intermitente, a lo largo de la cinta, y fijadas al elemento de seguridad, de polímero o celulosa, al menos por unas zonas destinadas a conformar unas porciones extremas de fijación del asa a una bolsa; de forma que en la posición de montaje la cinta de seguridad se encuentra fijada por sus extremos, conjuntamente con las porciones extremas de la tira plana, a la bolsa.  According to the invention, the layers of paper forming the flat strip are fixed to each other, continuously or intermittently, along the tape, and fixed to the security element, of polymer or cellulose, at least by areas intended for shaping end portions fixing the handle to a bag; so that in the mounting position the safety tape is fixed at its ends, together with the end portions of the flat strip, to the bag.
La fijación de las capas de papel solamente a los extremos opuestos del elemento de seguridad de polímero o celulosa, permite la posterior separación de ambos materiales para su reciclaje por separado. En el caso del polímero la totalidad del tramo central de las capas de papel se puede separar del elemento de seguridad de polímero mediante su rotura.The fixing of the paper layers only to the opposite ends of the polymer or cellulose safety element allows the subsequent separation of both materials for recycling separately. In the case of the polymer, the entire central section of the paper layers is It can separate from the polymer security element by breaking it.
En una realización de la invención la unión de las capas de papel con el elemento de seguridad de polímero se establece mediante un producto adhesivo. In an embodiment of the invention the union of the paper layers with the polymer security element is established by means of an adhesive product.
