Description

DESCRIPTION

Beverage filtration device

This utility model is part of the substance filtration technologies used in the food industry sector and consists of a filtration device for beverages that is applied to a glass or any other type of container for liquids.

STATE OF THE PRIOR ART

Filtration devices in the food industry sector have been used for a long time in different types and, therefore, in various fields of application. In the field of beverages, its function is to separate solid particles from the liquid mass.

During the preparation of the drink, various instruments are used to filter tea herbs or infusions in general, which usually appear as filters that can be applied directly to containers or glasses, with immersion devices (for example, sachets). For other types of drinks composed of solid-liquid mixtures, such as cocktails, so-called strainers can be used to filter the liquid during mixing and then pour the drink already purified of solid particles. Strainers can also be used when using leaf tea instead of tea bags.

On the other hand, in the beverage tasting phase, when liquids are drunk, the purpose of strainers is to prevent solid substances from being ingested with the drink, which would be unpleasant for the user. Although they are not used exclusively for this purpose, so-called straws are often used to taste drinks, with the function of separating the liquid from ice or other solid substances. These straws, although practical and widespread on the market, are most of the time disposable and therefore cannot be reused, which contributes to increasing environmental pollution. In fact, they consist of a product that is still used, very often, made of plastic material, which is not recyclable, to such an extent that its trade is currently very restricted in many states around the world.

Other filtration systems have been made that adapt solidly to the shape of the glass. A classic example is lids with a spout, well known in the cafeteria sector, used rather to provide an insulating barrier. Other more innovative examples They present a glass that includes a filter, which completely covers a cross section of the glass at a pre-established and non-modifiable height. Together with spout lids and the like, they belong to a category of filters that are closely linked to the design of your glass and are only applicable to it, which prevents its use from being extended to other containers. In particular, by providing the filter built into the glass (which can be decomposed into two blocks), it allows filtration only for the solid-liquid mixture contained in the lower block of the glass, underlying the filter. For example, the difficulty would arise in filtering the ice cubes usually contained throughout the glass. Indeed, ice tends to float and, if the glass is refilled once it has been manufactured, the ice would remain above the filter and would bother anyone drinking from it. Furthermore, as only a part of the volume of the glass can be filtered, limitations could arise in relation to the preparation of the solid-liquid drink and refilling after the first use.

SUMMARY DESCRIPTION OF THE INVENTION

It would be desirable to have a product that acts as a filter, that can be applied directly to the glass, that does not contaminate like a single-use straw, that therefore guarantees its reuse numerous times, and that adapts to different glass shapes.

The problem of replacing the straw, while maintaining its filtration capacity, is solved by making a filter of a rigid material, which has filtering grooves on a surface, which can be applied to any glass or any other type of container for liquids. , characterized by consisting of a conical body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

According to the present model, in order to solve the previous problem with a constructively simple and immediately applicable solution, a filter 1 is made (Figures 1A and 1B), which has a flat and conical shape, in this specific case of truncated conical shape, with a cylindrical blind cavity on one of its faces. Said filter 1 can be made of a rigid material, chosen from plastic, metal, glass or crystal. Examples of plastics could be polyethylene terephthalate (PET), high-density polyethylene (PE), polyvinyl chloride (PVC), low-density polyethylene (LDPE) and polypropylene (PP), while in what Regarding metals, aluminum (coated or uncoated) seems to be the best option due to its lightness and excellent corrosion resistance; However, other types of metals would also be appropriate, such as tinplate, stainless steel or copper.

The upper face (Fig. 1A) appears flat, while the lower face (Fig. 1B) is concave. In particular, the hollow part is constituted by said cylindrical cavity, closed transversely by a flat circular surface 2. The filter 1 is constituted, therefore, by a double lateral layer, an outer lateral layer 3 and an inner lateral layer 4. The lateral layer exterior 3 is designed to adhere during use to the interior part of a glass 6; Its truncated conical shape, as mentioned above, generates a particular slope that confers compatibility with a certain range of vessel diameters. The inner layer 4, part of the cylindrical cavity, constitutes the filtering surface, by cutting into it small filtering slots 5. Such slots 5, in this configuration, are generally a few millimeters wide and rectangular in shape, although they are possible other shapes, such as circular, square, triangular. They are distributed with vertical, oblique or horizontal orientation, regularly throughout the entire circumference of the inner lateral layer 4 of filter 1 (Fig. 1B).

The use of the filter 1 consists substantially of inserting it, coaxially with it, into a glass 6 containing the liquid to be filtered, with the lower face of the filter 1 (Fig. 1B) facing the bottom of the glass 6; The result of this application is illustrated in Figs. 2A and 2B. In this way, the filter can be used by inserting it inside a glass (6), in a transverse position with respect to said glass. The height with respect to the bottom of the vessel 6 in which the filter 1 will be mounted will depend on the external diameter 3 of the filter 1 and the internal diameter of the vessel 6. In fact, the surfaces will come into close contact, being fixed by coupling geometric, thus preventing the passage of liquid between them. The coupling that is created is not permanent, but, on the contrary, the filter can be removed from the glass at any time, before, after or during use. In addition to the geometric coupling, the fixation can be carried out by other means, such as by screwing, forming threads that interact on the inner surface of the glass 6 and on the outer surface of the filter 1. In this way, it is still possible for the liquid to pass only through the filter slots 5 of filter 1, which are, therefore, small enough to prevent the passage of solids, such as ice, leaves and aromatic herbs, fruits and other types of ingredients present in drinks. Substantially, the filter according to the present model allows any solid part to be separated from the drink, without distinction of composition, unlike the straw, which instead must maintain a certain permeability of the solids for functional reasons.

Any type of drink can lend itself to this application; The filtration capacity of filter 1 is determined by the width of its filter slots 5.

The rigid material from which it is made, thanks to good mechanical resistance, allows the filter 1 to be reused countless times, until it breaks, while maintaining perfect washability and adhesion to the interior walls of the glass.

Given its functional, geometric and structural characteristics, filter 1 guarantees a long useful life. It thus constitutes a sustainable and economical product, which effectively replaces disposable straws, which instead consist of a non-recyclable product. Furthermore, the conformation, which includes among other things the conical shape of the filter, allows it to adapt even to glasses that are slightly different in terms of size and function, while maintaining hygiene requirements thanks to the fact that it is washable. For example, it could be used for a cocktail glass, to filter ice and spices, thanks to the fact that it is applied from above, on the solids that may eventually float in the liquid, holding them firmly below it. Another example may consist of applying it to a glass of tea, so that the infused herbs are dispersed throughout the internal volume of the glass, thus also limiting the use of disposable tea bags.

It is understood, however, that the field provided by the model should not be considered limited to the particular provisions illustrated above, which are nothing more than examples of forms of execution thereof, but rather extends to more useful configurations, all of them at the same time. reach of an expert in the field, without thereby exceeding the scope of protection, which is solely defined by the claims that follow.
