 STRAW FOR LIQUID SUCTION

DESCRIPTION

OBJECT OF THE INVENTION

The present specification refers to a utility model related to a straw or cane for the suction of liquids constituted by a single hollow piece in its entire interior perimeter comprising an elongated tubular or rectilinear part and the molding, at any point of its length, of protuberances or plastic deformations, which may consist of different geometric shapes or a shape that represents any standard object such as a bottle, a doll, an airplane, etc. or a special form characteristic of a logo, brand or that represents objects that constitute the packaging of the same that can be used mainly but not exclusively as advertising support. The model that is claimed is a straw or cane, composed of a single piece that combines the typical tubular shape of the straw or cane itself and the geometric deformation that has been made on it that is also hollow by the flow of the liquid to Suction and is obtained mainly by extrusion blow molding.

FIELD OF THE INVENTION

This invention has its application in the promotional and advertising gift industry, in the food industry for the absorption of liquids, creams or purees more specifically, in the industry of alcoholic and non-alcoholic beverages and, in the hospitality and hospitality industries. household.

BACKGROUND OF THE INVENTION

The oldest straws were produced by the Sumerians of plant stems or literally straw to drink beer and filter the barley liquid. With the The advent of the industrial era Marvin Stone, a cigarette producer, found in the way to manufacture cigarette wrappings the basis for starting to manufacture artificial straws, production methods began to be developed that consisted of rolling paper sheets around a rod wax-coated manila (paraftna) that allowed its waterproofing and therefore its use to absorb liquids, so in the 1960s paper and laborious manufacturing processes were largely replaced by plastic. The explosion of plastic technology and the development of new materials has allowed its production to be less expensive and more sophisticated. Initially the straws were offered to the market as an option to prevent contact with the hands and body heat warming cold drinks, to avoid direct contact of the drinkers with the glasses to reduce the risk of contracting diseases, in the field of medicine to provide food and drink to people with an inability to move freely and research has continued to obtain so-called survival or life straws that include a carbon filter or iodine resin that eliminates bacteria and viruses from water whose function consists in purifying the water of some depressed areas of the planet avoiding death by infection of human beings.

Currently the straws are made in a wide variety of shapes and colors: basic straight and elongated texture from beginning to end, flexible, hard plastic with curves at the top (crazy plastic), individually packaged sanitary ware, special for hot drinks , with tapioca flavor that dissolves when milk passes over the tapioca that provides flavor and color, with decorative external elements etc.

However, the present invention, as we will detail in the description, incorporates a protuberance (3 and 4) to the suction tube (2) in such a way that it is part of the tube itself, the entire assembly constituting a single piece (1). The applicant is unaware of the existence of straws or liquid suction rods consisting of a single piece (1) that incorporates into the suction tube (2) a decorative protuberance and / or with the function of advertising support (3 and 4), DESCRIPTION OF THE INVENTION

The straws or reeds as they are generally called consist of a hollow tube inside that is used to suck liquids and / or as mixers or removers of combined and other refreshing drinks. Its use is very widespread to facilitate the absorption of liquids sold in tetrabrík containers, to capture the attention of a very young audience and to decorate cocktails and combinations in all types of hotel establishments, for this reason in a large number of occasions the food industry of Drinks and the plastics industry, order and produce decorated straws and / or that incorporate plastic decorative elements by direct clipping that contain shapes and / or logos.

These decorative and / or advertising elements are, as we have indicated, external and additional elements to the straw itself, they must be placed manually, since they are pieces other than the straw they make their production more expensive and have the risk of falling off falling into the liquid object of suction or excess pressure of the tube through which the liquid is absorbed.

The straw object of the present report (fig., 1, 2, 3, 4 and 5), is constituted by a hollow tube (1) in all its inner perimeter, which comprises an elongated tubular piece (2) that integrates a protuberance (3 and 4) consisting of standard geometric figures (3) or the representation of any object (4). The liquid that is absorbed through this piece (2) runs through the entire interior of it including the molded geometric figure {fig.6) until it reaches the user's mouth.

The geometric figures (3) and the representations of objects (4) constitute decorative elements of the straw (fig., 1, 2, 3, 4 and 5) by themselves and / or an excellent advertising medium for the diffusion of the own ones brands of the beverage industry, hospitality and all kinds of industries.

The manufacturing system preferably used is the so-called extrusion-blowing process whose technique gives plastic materials excellent physical characteristics because it modifies their molecular structure, increasing their resistance and avoiding any porosity of the material. This technology allows the extrusion process to be separated from each layer so that the plastic material more appropriate to the quality of the final product that is intended to be achieved or to the complexity of the reproductions of objects (4) that are intended to be implemented in the absorption tube (1) and allows the production of asymmetric pieces with maximum guarantees, at The products being formed by several layers, the manufacturing process gives them a total tightness and gives the products more efficient mechanical characteristics (lightness, strength, high temperature resistance, durability) and an optimal surface finish.

Blowing is a technique that is especially used for the manufacture of hollow plastic parts, usually containers, without the need to join two or more separately molded parts.

Therefore, the combination of this extrusion blow molding technique allows the production of relatively complex and irregular geometry pieces, variable wall thickness, double layers, high chemical resistance materials, etc. at very reasonable costs because the molds not having to withstand high pressures allow a wide range of materials for their construction.

In figure 7, in an explanatory, non-limiting way, the drawing of a mold assigned for the manufacture of straws with geometric figures (3) is shown and in figure 6 the section of a piece (1) made by this technique is appreciated .

The mechanical characteristics of these pieces (1) allow the protuberances that constitute the standard geometric pieces (3) and the representation of objects (4) to become an ideal advertising support by means of the impiementactón in the same of the images or corporate packages of companies through adhesives and stamping by any means such as screen printing, pad printing, digital, thermography (hot stamping, embossing or IML (In molding labeling)) Production using the technique indicated above allows us to obtain straws with decorative motifs for the suction of liquids constituted by a single piece at reduced costs that favors its commercialization to all kinds of industries whatever the nature of their sector (promotional gift, advertising, hospitality, household goods and health). Also, due to their hardness they can be reused on an x number of multiple occasions in the hospitality industry and can be recycled because they can be pulverized and melted again due to their thermoplastic nature, thus avoiding. To some extent, the creation of waste that affects the environment.

PREFERRED REALIZATION OF THE INVENTION

According to the figures provided and according to their numbering, the preferred and non-limiting embodiment of the invention can be observed, which consists of a straw or cane for the suction of liquids (fig., 1, 2, 3, 4 and 5 ), consisting of a single hollow piece (1) in its entire interior perimeter, comprising an elongated tubular piece (2) that integrates a protuberance constituted by standard geometric figures (3) or the representation of an object (4). The liquid that is absorbed through this piece (2) runs through the entire interior including geometric shapes (fig. 6) until it reaches the user's mouth.

The geometric figures (3) and the representations of objects (4) constitute decorative elements of the straw (figs. 1, 2, 3, 4 and 5) by themselves and / or an advertising support for the inclusion of different techniques such as pasted, stamped by screen printing, pad printing, digital, transfer, thermography (hot stamping), relief or IML (in mold labeiing), of corporate images and / or packaging of companies.

The straws are preferably manufactured using the extrusion-blow molding technique that allows the production of parts of relatively complex and irregular geometry, variable wall thickness, double layers and high chemical resistance materials at low cost because a single mold is used for the elaboration of the pieces (1) and because the range of materials used for the construction of molds that do not have to withstand high pressures is very varied.
