Description

Technical Field

The present invention refers to the technical field of containers for beverages in general and in particular it refers to a hygienic protection to prevent external contact contamination and similar.

State of the Art

By now the containers for cold or hot drinks are well known. These could include coffee' cups or glasses in general, and in particular the entire category of one-time disposable glasses or containers.
Specially in the public use, the hygiene is an indispensable prerogative to avoid the contamination by virus and pathogen agents of various nature. It is indeed known by everyone how the use of contaminated glasses could potentially expose everyone at a high risk. Often these last ones result to be very disturbing and weakening and often cause long and expensive antibiotic cures.
All the beverage's containers in general are subject to this risk, and in a particular way all the category of disposable containers, as plastic glasses and similar, caused by the fact that are essentially aimed for a public and crowded use. These last ones are indeed used commonly not only in the bars, but also in the offices or in the different occasions of parties and meetings and can easily become a way of diffusion of viruses when are not adequately protected.
All the disposable glasses are exclusively for individual use and, before using them, are unpacked from their packages and placed stacked on top of the other at user' s disposal. Often, when taking a glass, happens to take out of the stack more than one contemporarily. In this case the common reaction is to remove and replace on top of the stack the exceeding glasses and use only one of them. Unfortunately the handling operation of the glasses implies a contamination of all of their parts especially the ones that will be in contact with the lips of the user. It is clear how everything can be an easy mean of transmission of virus not only for third parties that will use the glasses that have been handled and replaced by the first user, but also for the same user.
Moreover it is clear how the sole and simple exposition to the external environment of all the glasses in general, regardless their being disposable or normal and simply stacked on top of the other or kept into apposite dispensers, can be a cause of contamination. Just thinking to all the glasses and containers in general exposed in a bar and subject to any kind of virus given by sneezes or cough of potential users.
Even the simple handling of the same, for example when the barman takes one in order to serve a drink, could represent a high risk of contamination if his hands are not completely sanitized.
Thus, it is cleat how this kind of contamination is difficult to prevent and almost unavoidable for all the containers in general, regret their being disposable or normal.
DE 567159 describes a protection against reuse of a glass to be removed before drinking.
WO 2005/120966 describes a detachable hygienic cap for a can.
FR 1429168 describes a single use hygienic protection to be fitted on a glass.
The above mentioned devices are however still not satisfactory in providing a protection easy to assemble to a common disposable glass and to handle for the user.

Disclosure of invention

It is therefore the aim on the present invention to give a protection device that resolves all the above mentioned inconvenient for all kinds of containers of beverages.
In particular it is the aim of the present invention to give a protective device that eliminates the risks of infection during the use of the containers and that is economical and easy to use.
These and other aims are reached through the present protection device for beverage's containers in general, particularly for plastic, paper, cardboard and similar disposable glasses and characterized by the fact that it comprises at least an annular collar comprising lateral walls and an upper junction base connected to them defining so an annular site. In this manner the annular collar is appropriate to bind, by means of said annular site and in a removable way, on the upper edge of the glass in such a manner to protect it from external contaminations.
The annular collar so realized can therefore be easily applied on the glass as a common lid. The grip will be guaranteed by the annular site that will receive the upper edge of the glass and a portion of the wall's height constituting the same glass.
Naturally the annular geometry of the collar, simply seen as a crown or annular configuration not exclusively circular but also with other shapes, allows exclusively the protection of the edge of the glass and of its wall's portion directed to the following contact with the lips during the use.
According to the invention the annular site of the above said collar comprises:

A lateral external wall tracing at least approximately the shape of the external face of the glass for a predetermined portion of its entire height and projecting downward from the upper edge of the same glass;
A lateral internal wall tracing at least approximately the shape of the internal face of the glass for a predetermined portion of its entire height and projecting downward from said upper edge of the glass;
The upper junction base to connect to each other said external lateral wall and said internal lateral wall. The connection happens from the side of the upper edge of the glass and in a manner that the upper junction base traces at least approximately the profile of the upper edge of the glass. In this way it is realized a receiving site that is opportunely shaped for the upper edge.

The annular collar, thus, is realized with the lateral external and internal wall that are complied with the shape of the wall. In this way it is obtained a constructive solution that is practically universal and adaptable, in each case, to each different geometry of the container.
The invention provides that the upper junction base comprises:

a first annular portion projecting from the internal wall upward and projecting toward the outside of the glass according to a first convex profile of a predetermined radius R₁;
a second annular portion projecting from the external wall upward and projecting toward the outside of the glass according to a second convex profile of a predetermined radius R2;
A third annular portion of junction of the apex of said first and said second portion defining the receiving site for the upper edge of the glass.

In this manner there is a receiving site that is opportunely shaped to contain the upper edge of the disposable plastic or similar glasses. The need of such shaping is found in the fact that, generally, this last one results typically curled or folded up to create a roundish supporting base for the lips that compensates the very thin thickness of the same glass. If indeed it was not complied this way, the upper edge would become dangerous and could cause painful cut of the lips.
Moreover, many times, the plastic glass presents kind of a collar close to its upper edge on the side of the internal wall. For this aim, then, the present device provides that the first annular portion is connected to the internal wall by means of a projection that gets extended in a radial way from the internal wall towards said first portion defining a step.
In order to remove the collar at the time of its use, are comprised opportune means of disjunction that comprise:

At least a tear-off tongue prolonging from a predetermined point of the external lateral wall and that gets projected downward;
A plurality of notches placed in correspondence of at least a side of said tongue and defining a tear-off line along at least a portion of the entire height of the collar, said notches having a predetermined pitch.

Advantageously the notches are placed in correspondence of both the sides of the tongue. Moreover the height of the notches can coincide to the entire height of the annular collar.
By simply pulling out the tongue, it is realized the tearing and the removal of the collar.
In all cases anyway it is possible to comprise the application of a protective film internally to the annular site of the collar and supplied with sterilizing substances.
In this way, when applying the protective device, there is already a sterilization of the same edge of the glass.
The present device can be produced separately or already integrated in the disposable glasses.
For this aim it is then possible to have a type of disposable glass in plastic, paper, cardboard and similar characterized by the fact that it comprises in correspondence of its upper edge a protection device as described.

Description of some pattern realizations

In figure 1 and figure 3 it is therefore described an appropriate device able to resolve all the above said inconvenient.
In particular, an annular collar 1 is realized through a couple of lateral walls (3, 4) connected to each other by an upper junction base 5, in a way to realize an annular site 6. The annular site so obtained (look at figure 3), will receive in its inside a predetermined portion of the height of the glass' s wall 7 comprising also its upper edge 8.
In particular, figure 3 shows in detail a possible section of the annular collar comprising the external lateral wall 4 and the internal lateral wall 3, which follow the profile of the glass. In this way, the annular denomination of the collar is not exclusively limited to a circular geometry, but also to any geometry tracing the profile of the container. The upper junction base 5 allows then to connect to each other the two walls by following approximately the profile of the upper edge 8 of the glass. In this way it is realized the annular site 6 receiving the wall's portion 7 of the glass and of the same upper edge 8.
The height of the two lateral walls 3 and 4, respectively external and internal, can vary at someone's taste without having to move apart from the present inventive concept. In this way the collar will keep a height of the glass's wall 7 that is more or less wide including, naturally, its upper edge 8.
The section of the collar can also comprise different shapes and geometries, according to the needs and specific applications and, hereinafter, are described few of the preferred ones. The numbering has been increased of a hundred for each preferred described configuration only for the aim of clarity of interpretation and thus in an absolute not limitative manner.
According to a first preferred configuration of the invention (look at figure 4) the upper junction base 5 is adjusted in such a way to realize a receiving site 109 for the upper edge 108 of the glass as described later on. A first annular portion 110 results emerging from the internal wall 103 upwards and projecting toward the outside of the glass according to a first convex profile of predetermined radius R₁. A second annular portion 111 is on the other hand emerging upward from the external wall 104. Also this second portion results projected towards the outside of the glass according to a second convex profile of predetermined radius R₂. The two above mentioned portions are then joined to each other through a straightaway or with a predetermined radius of curvature third junction annular portion 112. In this way it is realized the receiving site 109 for the upper edge of the glass.
Naturally the receiving site 109 has been described by dividing it in the above mentioned portions (110, 111, 112) exclusively for geometry's clearness and thus not limited for the present invention. This first configuration results particularly advantageous in the case of disposable glasses which, often, present an upper edge 108 shaped as a curl. The disposable glasses are all considered one-time glasses in general and commonly realize in materials as plastic, paper, cardboard, polyester and similar.
The disposable glasses, in general, present a sort of step 113 (look at figure 5). For this reason it is then possible to modify the collar in a way that the first annular portion 110 is connected to the internal wall 103 through a portion 114 that gets extended annularly in a radial way from the internal wall towards said first annular portion 110.Indeed, in this case the step can be used and utilized as a stopper step during the insertion of the collar.
Only for comparative purposes figures 6 and 7 illustrate a configuration different from that of the invention. It provides on the other hand that the upper junction base 5 is realized with an annular cup shape 210 or similar with a predermined radius R₃.The cup results, also in this case, projecting from both the external 204 and internal 203 lateral walls defining this way also this other new receiving site 209.
Another configuration different from that of the invention (look at figure 8), preferably usable in all types of container for liquid as cups or glasses in general and thus not only disposable, comprises a very simple upper junction base 5, or rather a junction 310 with a profile that is almost rectilinear to connect the two walls 303 and 304.
In all the preferred configurations of the invention can be provided means of disjunction 17 (look for example figure 1 and 2). These last ones are needed to remove from the glass, at the time of its use, the protective collar. In particular a tear-off tongue 18 gets projected from a predetermined point of the external lateral wall 4 downward; In correspondence to one or both of its sides are then found a plurality of notching 19 that can comprise the entire or a portion of the height of the collar and that define tear-off lines of predetermined steps.
In all the described configuration is possible to apply a protective film inside the annular site of the collar and provided with sterilizing substances as bactericides or disinfectant in general. In this way, the protective film will get in contact to the edge of the glass as soon as the collar is applied, exercising consequently an action of sterilization of the same edge from any external bacterial that can eventually exist.
It is now described the functioning of the device that results common for all the constructive configurations. For this aim, in a non restrictive manner, it is been chosen to refer to some explicative figures.
As described in figure 1 and 2 the collar 1 can be applied on the upper edge 8 of the glass before exposing it to the public. Alternatively nothing would avoid the realization, for example, of disposable glasses already prearranged with the protective collar. Nothing, thus, would avoid the realization at an industrial scale of disposable glasses already prearranged and packed with such protection. In this way, by simply taking them out from the package and by placing them in the specific dispensers, they result to be ready for the use without any risk of contamination.
With the aim to guarantee the holding of the collar (look at figure 10) it is possible to take advantage of the elasticity of the same material and its geometry. In particular for all the solutions applied to the containers that have the upper edge folded (look the cases of figure 4, 5 and 7), the action of insertion causes the opening of the external and internal lateral walls against the upper edge 8. Once the collar is completely inserted, the edge 8 will be contained within its receiving site realizing practically a snap engage.
In other case where the upper edge of the glass is not shaped (look at figure 8 and figure 9), it could be applied a simple insertion or a simple interference. In this case, then, the means of disjunction 17 are not needed anymore being able to remove the collar by simply lifting it (look at figure 9). This, as already said, is a typical case of the use of the invention on common glasses in glass or coffee' cups in ceramics and similar where the edge is linear.
In all the other described cases, the removal of the collar is also a simple operation. Operating simply on the tongue 18 by pulling it, there will be a tearing along the entire predefined tear-off line 19 allowing the complete removal of the collar.
The realization of the present device can consist, for example, in a material moulding. In the case of realization of the annular collar already integrated in the disposable glasses, it is then necessary to have a new additional phase of realization of the glasses that comprises the production and the following application of the collar on the glass within the production run of the glass.
The materials for the realization of the present device can then be, in an absolutely not limitative manner, all the materials suitable to have such protective function.
It is at this point clear how all the aims of the present inventing have been reached. In particular it is clear how the collar resolves all the risks of infection and contamination from the contact of the lips to the edge of a container that is mostly contaminated.
Indeed, in the case of glasses or coffee cups in general, it is possible to replace on them the disposable protective collar once they have been washed, avoiding this way any possible contamination. In the case of disposable glasses is possible to protect the edge in the same manner before arranging them to the public.
