Device for keeping a crown cap on the bottle after opening

Abstract

Device for keeping a crown cap on a bottle after opening, characterized in that the device comprises a ring element for attachment to the bottle neck and a connecting element between the ring element and the crown cap.

Description

1. Technical field

[0001] The invention relates to a device for attaching a crown cap to a beverage bottle after opening, in particular to prevent loss or environmental pollution caused by discarded crown caps. 2. State of the art

[0002] Crown caps are typically removed completely from the bottle after opening and are often not reused. This leads to a significant amount of waste, especially at events or in public spaces. Reusable closures or retention systems for crown caps are currently unknown or only usable in conjunction with specific bottle shapes. 3. Object of the invention

[0003] The object of the invention is to create a simple, cost-effective and retrofittable solution that allows a crown cap to remain permanently attached to the bottle after opening, without significantly impairing its function or use. 4. Solution according to utility model

[0004] This task is solved by a device consisting of: - a ring element that can be placed or attached around the neck of the bottle, - a connecting element (e.g., band, wire, bridge) between the ring element and the crown cap, the crown cap is attached to the connecting element and remains on the bottle after opening.

[0005] For this purpose, the crown cap preferably has a small hole or tab through which the connecting element is guided.

[0006] The ring element can be made of flexible plastic or wire and has a slot or opening mechanism so that it can be applied to standard bottle necks without any additional tools. 5. Advantages of the invention - No modification of the bottle or bottle neck is required - Easy retrofitting for standard crown caps - Low production costs - Contribution to waste prevention and environmental friendliness - Ideal solution for event organizers, breweries and beverage retailers 6. Examples of Implementation

[0007] One embodiment shows a device with a polypropylene ring approximately 5 mm wide and with an inner diameter of approximately 30 mm. A connecting element made of plastic tape, approximately 3 cm long, is inserted through a 2 mm hole in the rim of the crown cap and knotted or welded there. The other end is permanently attached to the ring. After the bottle is opened, the crown cap remains attached to the ring, which is positioned around the bottle neck. When the bottle is returned, the crown cap can thus be recycled.

[0008] Another embodiment shows a device made of wire. A wire loop is placed around the neck of the bottle. The other end of the wire loop is connected to the crown cap by a small tab or through a small hole outside the sealing area. When the bottle is opened, the crown cap remains attached to the wire and can be recycled when the bottle is returned.

Claims

[1] Device for keeping a crown cap on a bottle after opening, characterized by that the device comprises a ring element for attachment to the bottle neck and a connecting element between the ring element and the crown cap. [2] Device according to claim 1, characterized by that the crown cap has an opening for attaching the connecting element. [3] Device according to any one of the preceding claims, characterized by that the ring element is made of flexible plastic and has a slot for clipping onto the bottle neck. [4] Device according to any one of the preceding claims, characterized by that the connecting element is a band, wire, ring, clip, textile thread or a plastic part integrally connected to the ring element. [5] Use of the device according to any of the preceding claims to prevent environmental pollution caused by lost bottle caps.
