ITTA20150003A1 - FOLDING DISPOSABLE CUP WITH HIGH HYGIENIC PROPERTIES - Google Patents

Description

The present document has as its object a foldable disposable cup for drinks and liquids in general, the main peculiarities of which are to have a flat shape before use and to possess high hygienic properties.

STATE OF THE ART

As is known, the market for disposable cups, ie "disposable", is essentially represented by containers having a truncated cone shape; they are mostly made of plastic but there are also some in plasticized paper and polystyrene.

The disposable cups of the known art are already preformed and generally sold in multipacks.

Where it is required to comply with specific hygiene rules, as in the case of fast food, health facilities or hotels, the glasses are packed individually.

In the latter case, the operation of packing the individual glasses represents a significant higher cost; furthermore, the overall dimensions of the packaging are very high when compared to the very low weight, making this type of container very disadvantageous.

The aim of the present invention? to solve the problem and the drawbacks outlined above through a foldable disposable cup with high properties? hygienic products that can be packaged in a flat shape, with minimum bulk characteristics and excellent hygienic guarantees.

It can? advantageously be made of polythene-coated paper material, or other plasticized material.

The present invention does not necessarily compete with the plastic cups currently on the market but assigns itself the task of defining a new market segment in which the traditional disposable cup? absent why? totally unsuitable. Ultimately, in virtue? due to its small footprint, the present invention is intended to represent for the user a personal "pocket-sized" equipment, being able to conveniently pack it for sale, in multiple packs of 5/10 pieces.

And in fact we rarely carry a glass with us, and just as rarely is it found in a bag, in a schoolboy's backpack or even in our car; the reason ? that the disposable glasses currently on the market are bulky and easily damaged.

Of course, by virtue of? of its properties? hygienic and of the minimum encumbrance, with greater value the present invention can? compete with traditional disposable cups for use in fast food restaurants, health facilities, military facilities, hotels and any other public place where drinks are administered.

Within the same task, a particular purpose of the trot? that to make a disposable cup with high hygienic properties that assumes the conformation of use with a simple and quick manual operation.

The glass object of the present invention, due to its particular constructive characteristics, offers the most? ample guarantees of reliability? and safety in use, and? easily achievable using commonly available materials? on the market. Furthermore, the advantages deriving from the minimum footprint in the production cycle and distribution make it competitive from an economic point of view.

The above task as well as? the purposes mentioned above and others, which will appear better highlighted later, are achieved by a foldable disposable cup with high properties. hygienic, according to the invention, characterized by the fact that they can assume two configurations, one of a closed cup, having minimal bulk due to its flat shape, and the other of an open cup for use.

It ? consisting of two casings, one inside the other, in which the internal casing has the function of assuming a three-dimensional shape stabilized through particular folding lines while the external casing has the task of defining a stable support base and a mouth of opening, having a pseudo-circular shape.

The outer shell? consisting of a sheet-like body folded in such a way as to define two faces, preferably rectangular, which are joined together only along the lateral edges while the upper and lower edges are not joined together.

The internal envelope, also made up of a sheet-like body,? employed in order to define two faces; as along the two side edges, along the bottom edge and partially along the top edge.

On the two faces of the internal envelope there are symmetrically provided curvilinear and rectilinear folding lines suitable for determining the weakening of the sheet-like body to allow its folding in order to make it assume a three-dimensional container shape.

The upper edge of the external envelope, which constitutes the mouth of the glass, can? be equipped with a removable seal in order to enhance the propnet? hygiene of the glass itself.

DESCRIPTION OF THE DRAWINGS

Further characteristics and advantages of the invention, object of the present invention, will become more evident through an examination of the detailed description of a preferred, but not exclusive, embodiment of a folding disposable cup with high properties. hygienic, illustrated as an indication, but not limited to, with the help of the attached drawings in which:

? Figures 1 and 2 show, in axonometric view, the socket respectively in the flat configuration and in the opening configuration;

? Figures 3 and 4 show, in axonometric view, the socket respectively in the flat configuration and in the opening configuration, with the internal casing outlined in broken lines;

? Figures 5 and 6 show the open cup, with the internal casing outlined in broken lines, respectively in front and side views;

? Figures 7 and 8 show the open cup, respectively in top view and in bottom view;

? Figure 9 is a front view of the outer casing in a flat configuration;

? Figure 10 is a front view of the internal casing in a flat configuration;

? figure 11 shows, in front view, the internal casing in a flat configuration, with detail of the parts that fold when the cup is opened;

? Figures 12, 13 and 14 show the internal casing in the opening configuration, respectively in an axonometric view, in a front view and in a side view.

With particular reference to the numerical symbols of the aforementioned figures, the disposable cup with high properties? hygienic, according to the invention, indicated in its entirety? with the reference number (1), it includes an external casing (2) and an internal casing (3), both made of polythene paper material, or other plasticized material, so as to give a certain consistency and the due impermeability.

The external envelope (2), in the flat shape, is made up of two faces (4), joined together along the lateral edges (5), which can be obtained by joining two separate sheets or by folding a single sheet presenting the meeting anywhere on the surface; the lateral edges (5) can be parallel to each other or have a convergent trend towards the bottom, being able to give the open glass a pseudo cylindrical or truncated conical shape; the lower (6) and upper (7) edges are not joined together.

The inner shell (3)? also made up of two faces (8) of a width slightly less than those of the external envelope (2), just enough to allow it? gluing inside; they can be obtained by joining two separate sheets or by folding a single sheet that presents the meeting in any point of the surface; the faces (8) have a pseudo-rectangular shape, with the upper edge shaped to define a central part (11) pi? protruding with respect to the two remaining lateral parts (12, 14); the two faces (8) are joined along the two lateral edges (9), along the lower edge (10) and along the pi? protruding upper edge (11).

The curvilinear (15, 16) and rectilinear (17) folding lines present on the faces of the internal casing (3) have the function of weakening the sheet-like body to allow its folding in order to make it take on a three-dimensional form of container in which the peripheral parts (8b, 8c), of the faces (8) which are folded, form curved surfaces suitable to keep the intermediate parts (8a) open.

The curvilinear bending lines (16, 15) of the internal envelope (3) developing respectively between the lower vertices (19) and between the upper intermediate vertices (13), are specifically determined to represent the geometric locus of the points having distance , respectively from the bottom line (10) and from the top line? (11), such that the envelope, in the container configuration, assumes a pseudo-cylindrical shape.

The lower vertical fold lines (17) of the inner casing (3), which develop between the lower edge 10 and the curved line 16 ;, have the function of weakening the lower edge (10) to facilitate the deformation of the casing (3).

The inner shell (3)? pi? lower than the external one (2) and d? joined to it in the position where its lower vertices (19) coincide with the homologous vertices of the external envelope while its upper part corresponds to the intermediate part of the external envelope (2); this because of the necessity? that the upper curved surfaces (8c) of the internal casing (3) which are determined at the opening of the cup, are at a convenient distance from the mouth (7) of the cup itself and do not obstruct its filling.

The union between the two casings, to be made preferably but not exclusively by gluing, will interest? the median part (8a) of the internal envelope (3) or the part delimited by the curvilinear folding lines (15, 16); this is to ensure that the peripheral parts (8b, 8c) of the internal envelope (3), i.e. those external to the said curvilinear fold lines (15, 16), remain free to fold to allow the deformation of the envelope with the assuming a form of container.

The broken parts (12, 14) of the upper edge of the two faces (8) of the inner casing (3), unlike the central part of the same upper edge (11), are not constrained to each other, being free to move away reciprocally to define, in the open casing configuration, two holes (20) having the function of making the volumes of the two casings communicating and allowing the poured liquid to occupy them. also be made in two separate parts or a lower part intended to spread and keep open the bottom of the glass and an upper part designed to spread and keep the mouth of the glass open.

Peculiar characteristic of the present invention? that the opening of the cup (1), once the protection seal has been removed, takes place by pressing the opposite side edges (5) towards each other; the faces of the two envelopes will spread apart, curving; the internal envelope (3), due to its own folding lines (15, 16, 17), will deform? until it stabilizes, inducing to the external faces (4) of the external envelope (2) a pseudo-cylindrical shape of a glass with a stable support base (6) and an opening mouth (7), having a pseudo-circular shape.

From what has been previously described, you can? to note how the invention achieves the intended aim and objects.

The invention thus conceived? susceptible of variants and modifications, all of which are within the scope of the inventive concept.

In practice, the materials used, provided? compatible with the specific food use, as well as? the contingent shapes and dimensions may be any according to requirements.
