Abstract

The invention relates to a protective device for drinks cans. The inventive device consists of a thin, deformable discoid body comprising numerous radia l notches along the periphery thereof. Internally, the device comprises a seri es of curvilinear cuts which are concentric with the edge of the disk, thereby defining peripheral areas which are intended to be positioned below the uppe r rim at the top of the cylindrical body of the can.

Description

FIELD OF THE INVENTION
5 The present invention relates to a protective device for drink cans.
As stated in the title, there is provided an element applicable to a can of the type used for containing soft drinks and the tike, for protecting it against external agents.
io BACKGROUND OF THE INVENTION
As is known, cans of the above type are exposed, while stored, to various agents such as dust, dirt, and other materials, which may 15 contaminate the outer surface of those cans, just at the region that remains in contact with a person's lips when the liquid contained is consumed, as is common practice, by sucking directly from the can.
Until recently, apart from a simple lid in the form of a cyliridrical disk of a very short height relative to its diameter, and Spanish 2 o Utility Model U~1991209, no practical and cost effective device was known that prevents dirt from being formed on a drink can.
A cylindrical lid of the above type has many disadvantages: it must be applied to the outside of the can top rim, so that it may be easily released, and therefore its protective feature may get lost, and in addition it 25 has to be made from a material such as plastic whereby its cost has to be taken into consideration.
SUMMARY OF THE INVENTION
The device which will be now described allows overcoming the 3o above mentioned disadvantages. 1t consists of a discoidal member which is applied to the top of a can for soft drinks or the tike, and is temporarily retained thereto, covering said portion and thus preventing dust and other materials from being farmed thereon.
When the user is going to drink from the can the protective 35 member is first detached, this operation being carried out with hardly any effort, Leaving the can top and the closure member thereof accessible; these will be clean precisely due to the insulating function of the protective device.
For ease of disclosure, the present description is accompanied by drawings in which one case of embodiment of a protective device for drink s cans is shown by way of an illustrative and non-limitative example according to the principles of the claims.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is a top plan and side elevational view of the new to protective device for drink cans.
Fig.2 shows, in an enlarged, fragmentary view, the position of the protective device on a can of the above mentioned type.
DETAILED DESCRIPTION OF THE INVENTION
~s The elements indicated by the reference numerals in the drawings correspond to the parts referenced herein below.
The protective device of this patent consists of a thin body 1 which is preferably circular in shape (even though it could also take other forms, made from an easily deformable material, such as, for example, 2 o cardboard, plastic or metal.
The body 1 has, on its periphery, a number of radial notches 2 which are advantageously angular in shape, with their vertexes facing the center of the piece.
Likewise, the body 1 has curvilinear cuts 3, concentric with the 2s edges of the body itself and at a distance from them similar to the length of the radial notches 2.
The can 4 is of the known type having at the top of its cylindrical body a frustoconical portion 5 and a concentric rim 6.

3 a POSITIONING AND USE OF THE DEVICE
follows:
The described protective device is positioned on a drink can as The disk 1 is positioned overlapping and centred on the rim 6 35 (whereby it will protect the central portion of the upper base of the body 4), and thus the peripheral areas 7 defined by the cuts 3 project from the rim itself. Subsequently, a slight force is applied to said areas 7 resulting in their downward flexion which is facilitated by the radial notches 2. The cuts 3 are positioned with their lower sides located below the rim 6, resulting in that the S disk 1 remains attached to the body 4 of the can.
The frustoconical portion 5, which will also be in contact with the uses lips, is protected by the protruding areas 7 and it is sheltered from dust and other materials.
When the contents of the can is going to be consumed, the to described device is easily detached by applying a slight force in the direction of lifting the flanges formed by the peripheral areas 7.
Furthermore, the device itself may form an excellent advertising carrier, since logos and inscriptions regarding the product contained therein or other products and services may be included on one or both of its two faces.
1s The number of notches 2 and cuts 3 may be varied in accordance with the size of the disk 1 and the can 4.

Claims

1. Protective device for drink cans, of the type intended to be placed on the upper base of a can, characterised in that it consists in a thin body (1) having advantageously a discoidal shape and made from an easily deformable material, provided on its periphery with a number of radial notches (2) which are substantially angular in shape and a number of curvilinear cuts (3), concentric with the edges of the disk (1) and arranged between the notches (2), defining peripheral areas (7) which can be arranged by flexion below the upper rim (6) formed on the upper portion (5) of the cylindrical body (4) of a can.
