Bottle stopper with insect-proof drinking grid and passive leak protection, especially for bottles with crown cap closures

Abstract

Bottle closure (1) for beverage bottles with crown cap mouth, comprising a closure body with a side wall (2) which can be placed on the bottle neck and a lid surface (7) with a central drinking opening (3), characterized in that the drinking opening (3) is closed by an integrated fine mesh grid (4) which prevents the penetration of insects and reduces leakage when the bottle is tipped over due to surface tension.

Description

Technical field

[0001] The present invention relates to a reusable bottle closure for beverage bottles, in particular for bottles with crown cap closures. The closure allows drinking directly from an opened bottle, while simultaneously preventing the ingress of insects and reducing leakage when the bottle tips over, thanks to a special grid structure. The invention belongs to the field of closures for beverage packaging. State of the art

[0002] Various covers and closures designed to protect beverage bottles from insects are known in the prior art. These often consist of removable lids, flaps, or screens that must be removed or operated before drinking. Other solutions completely seal the bottle and require the opening of a separate drinking valve.

[0003] A major problem with these existing solutions is that either direct drinking is not possible, or liquid leaks out freely if the bottle tips over. Furthermore, many systems are multi-part, mechanically complex, and therefore prone to malfunction or expensive to manufacture.

[0004] Therefore, there is a need for a simply constructed, insect-proof drinking closure that allows direct drinking while simultaneously providing leakage protection through surface tension. Object of the invention

[0005] The object of the invention is to provide a bottle closure that: • Universally fits standard beverage bottles with crown cap openings, • reliably prevents the ingress of insects, • leakage when the bottle tips over is reduced by surface tension, • consists of a single-piece plastic component, • inexpensive to manufacture, durable and easy to clean, • and additionally has an eyelet for carabiners or loops to make the closure portable. Solution to the task

[0006] This task is solved by a bottle closure that is manufactured in one piece from PETG (polyethylene terephthalate glycol) using an injection molding process.

[0007] The bottle cap has the following components: • a side wall (2) that can be placed on the neck of a standard crown cap bottle, • a lid surface (7) with a central drinking opening (3), • a fine mesh grid (4) integrated into this opening, • an internal locking projection (6) for engagement under the crimped edge of the bottle mouth, • a side-mounted eyelet (5) for attaching a carabiner or carrying strap.

[0008] The grid prevents insects from entering while still allowing drinking from the bottle. Due to its small mesh size, surface tension prevents the liquid from leaking out if the bottle tips over. Detailed description of the invention (without drawings)

[0009] The bottle closure (1) comprises a side wall (2) that can be placed on the neck of a beverage bottle with a crown cap closure. The side wall (2) has an internal locking projection (6) that engages under the crimped edge of the bottle mouth and secures the closure.

[0010] The lid surface (7) completely seals the bottle opening and contains a central drinking opening (3). This opening is closed by an integrated fine mesh grid (4).

[0011] The grid (4) is designed such that the clear opening of the mesh is less than 2 mm, preferably about 0.3 mm. This ensures that neither bees nor wasps can pass through it. The dimensions are also chosen so that the surface tension of the liquid prevents leakage when the grid is tipped over.

[0012] The grid (4) has a total length of approximately 22.11 mm and a total surface area of ​​approximately 160.7 mm². 2 This dimensioning ensures that sufficient flow is achieved when drinking, without impairing the protective effect.

[0013] An eyelet (5) is provided on the outside of the closure, which allows the attachment of a carabiner or a carrying strap, so that the bottle can be transported conveniently. Advantages of the invention • Insect protection: No bees or wasps can get into the bottle. • Leak protection: The fine mesh prevents the drink from spilling due to surface tension when the container tips over. • Direct drinking: No need to remove the cap. • One-piece design: No individual parts, no assembly required, high robustness. • Universal fit: Suitable for all standard crown cap bottles. • Portability: Eyelet allows attachment to a backpack, belt or bag. • Easy cleaning: PETG is dishwasher safe and food safe.
