Abstract

The plastic capsule, especially for large-volume bottles for use in dispensers, includes an openable zone (4) which is accessible from the outside and closed by a cap (3) is externally protected by a disc (5) which is made in a single piece with the capsule. The cap (3) is peripherally connected to the openable zone by easy-break ribs (6) and also by a thin annular skin (6a) which hermetically closes an annular space existing between the upper surface (1a) of the capsule and the disc (5).

Claims

1. ). A plastic capsule (1) for large bottles (2), comprising:

an openable zone (4), delimited by a cylindrical wall (1d) projecting coaxially from an upper surface (1a) of the capsule, which openable zone (4) is accessible from outside and is closed by a cap (3), and through which openable zone a liquid, usually water, is removed from the bottle;

further comprising a protection element for the openable zone (4);

wherein a disc (5) is provided, located superiorly of the openable zone (4) and made in a single piece with the capsule, which disc (5) is peripherally connected to the cylindrical wall (1d) of the openable zone (4) by means of easy-break ribs (6), and is coplanar to the upper surface (1a) of the capsule (1);

the disc (5) comprising a thin annular skin (6a), made in a single piece with the capsule and being much thinner than the upper surface (1a) of the disc (5) and the easy-break ribs (6), which annular skin (6a) hermetically closes an annular space existing between the upper surface (1a) of the capsule and the disc (5) and together with the disc (5) constitutes the protection element.

2. ). The capsule of claim 1, comprising an external annular hoop (1c) which, when the capsule is mounted on the bottle, rests on an annular projection (2a) of a neck of the bottle in such a way as not to project laterally from the neck of the bottle.

3. ). The capsule of claim 1, comprising:

an internal annular hoop (1b), afforded internally and coaxially of the capsule (1), which projects from an internal surface of the capsule (1) and inserts sealingly internally of a mouth of the bottle (2) when the capsule (1) is applied on the bottle (2).

4. ). The capsule of claim 3, comprising an internal annular projection (1e), afforded internally of the capsule (1), which internal annular projection (1e), together with the internal annular hoop (1b), defines a seating in which an external annular projection (2b) fashioned on an external surface of the neck of the bottle (2) inserts when the capsule is mounted on the bottle (2).

5. ). The capsule of claim 2, wherein an upper part of the capsule (1) has a slightly smaller diameter than a diameter of the external annular hoop (1c) and defines, in the connection zone between the external annular hoop (1c) and the upper part of the capsule (1), an annular projection (1f) having a hook-shaped section.

6. ). The capsule of claim 1, wherein the capsule (1) is manufactured by injection-moulding, and is made of plastic for use with foodstuffs.

7. ). The capsule of claim 1, comprising two easy-break ribs (6) which are in diametrically opposed positions.
