Description

Hygienic closure for boxes containing drinks. The current

invention relates to a closure

  hygienic for boxes containing drinks.

  As is well known, the use of metal boxes is becoming more and more widespread for the presentation of beverages such as refreshments,

  beers, etc. This growing job is easily explained

  because these metal containers together

  many advantages both in terms of

  do not preserve their content in excellent

  that the ease of storage and trans-

  port, the economy, the ease of opening as well as the convenience of consumption, since, in the vast majority of cases, these containers once opened are immediately used as glasses to drink for the consumption of their contents . And it is precisely under this last form of employment that the receptacles in question present the only serious disadvantage of which they suffer. It is indeed obvious that the direct use of these containers as glasses, by applying the lips on their edge, is

  contrary to the most basic principles of

  since, until the moment of their use,

  As a drinking glass, the containers have been transported, stored and handled without the slightest

  precaution and have come into contact with all

  substances and contaminants. The

  lyses performed on the surface of samples of these

  containers offered for consumption have given rise to

  frankly alarming results. The present invention makes it possible to eliminate this disadvantage radically, and this in an extremely simple and economical way, without

  substantially increase packaging costs, and

  it is more difficult for consumers to use containers. In these circumstances, the advantages

  practices resulting from the invention do not require

special applications.

  In order to achieve the above effects, the farm

  hygienic treatment which is the subject of the present invention.

  The invention is characterized in that it consists of a body of laminar structure and of flexible nature, such as plastic, waterproofed paper, a metal foil; this integral body is adapted to the outer surface of the box, to which it is fixed by means of an adhesive which can not alter the taste or any other characteristic of the contents

  container and withstands changes in temperature.

  erated and, as a result, is entirely unsafe for the consumer. This adhesive is preferably incorporated

  to the aforementioned laminar body during the process of

  the latter, which will, therefore,

  as a self-adhesive element. But it is also

  as possible, as it is easy to understand.

  dre, to achieve the contribution of adhesive in the process of placement and fixation of the laminar body on the

corresponding container.

  Said laminar body is placed on the container so that it extends over part of the base

  top of this container by covering and isolating

  lant from the outside, and on a portion of the edge and sidewalls, largely enveloping the area in which the user will apply his lips to consume the content, so that this part is also isolated from the outside. Following an important characteristic of

  the invention, the laminar protective body is

  in order to cover at least part of the

  detachable tongue through which the

  Verture; so when the tongue is torn off and

  detached, there is also a total detachment of

said laminar body.

  In these conditions it is understood that it will be sufficient to operate the opening of the box, in a normal way,

  by pulling on the ring or a similar solidary element

  the tongue, to provoke, at the same time, the

  detachment of the closing blade leaving

  covered an area of the walls of the box which, being

  remain: permanently covered and protected

  that at the moment of opening, will be perfectly

close and sterilized.

  Among the perquisites presented by

  the invention, it can be pointed out that the self-closing

  adhesive can be used once the

  container opening, to determine the fixation of

  the detachable tongue at any lateral point

  than the surface of this container, with advantages

  obvious for the cleanliness of the environment. In-

  and also as an additional benefit, the hygienic closure can be used as a support

  for the printing of all kinds of advertising

  instructions for the consumption of

  held container, etc .; it is also possible to print on it, preferably on its underside, which remains hidden until the opening, games, contests, signs, giving entitlement to specified bonuses, etc. For the sole purpose of clarifying and clarifying

  has just been explained, this Memorial is accompanied by

  a sheet of drawings, on which, in

  schematic and, consequently, without any

  was a concrete example of reali-

  practical use of the hygienic closure which

  destroys the object of the present invention.

  In these drawings: Figure 1 is a perspective view of

  the whole of a box equipped with the system of

according to the present invention.

  FIG. 2 is a detail in section according to a

  plane passing through a diameter, to a larger scale

  the, of the box shown in Figure 1 above.

  The invention will apply, as it has already been

  indicated, to a standard box, of the type used

  for the presentation of drinks. These kinds of boxes generally assume a cylindrical shape with side walls 1 joined to the base 2 by

  a rim 3, and are equipped on this basis with a lan-

  watch 4, united to the rest of the box by a low resistance line 5 easily tearable and endowed

  of a ring or a handle 6, on which one can exert

  the desired traction to cause the opening. However, it is understood that the concrete characteristics of the box (shape, proportions, structure, opening system, etc.) are in themselves totally foreign to the present invention and that, consequently, they

  may vary within the wider limits without

  from the field of protection of the present invention.

  In addition, the present invention is also perfectly applicable to containers made in whole or in part of non-metallic materials, such as plastic, cardboard, etc.

  What is essential, in accordance with the

  verntion is that on the box and in the way

  Ia stated, is arranged and fixed, by means of a suitable adhesive, a flexible laminar body, formed in the concrete example shown in the accompanying drawings,

  two independent rooms, designated respectively

  7 and 8. One, 7, of these parts

  these covers a part of the base 2 and is located, at least partially, on the detachable tongue 4, while the other part 8 covers part of the side walls 1. The part 7 also extends on a high area of these walls and is covered by the piece 8 so that tearing the tongue 4 is

  causes at the same time, automatically and ne-

  necessary, the detachment of the first coin, which

the train and detach the second.

  The division of the protective laminar body

  two independent pieces presents a series of advancements

  especially with regard to the implementation of

  this automatic closing on the box, but it

  It is easy to understand that, without

  important, the laminar body could be

  also made of a single piece, or, alternatively,

  may also consist of three or more rooms, arranged in such a way that the detachment of the first leads to that of the second, and so

right now.

  Finally, it is also understood that the placing and fixing of the protective body on the

  box should be carried out after cleaning and

  sterilization at least

  this box on which the adhesive will have to apply.

  For this purpose, it will also be possible for sterility

  Finally, it is necessary to point out

  general and expresses that, as it is understandable

  In addition to those which have already been indicated, it will be possible to introduce, in the practical embodiment of the hygienic closure for cans described here, all additions and modifications of detail which do not relate to what

  constitutes the essence of the patent applied for.
