Reusable drinking bottle with fully opening halves and removable caps for complete cleaning.

Abstract

Reusable drinking bottle consisting of two completely separable and / or hinged half-shells which, in the closed position, form a tight, liquid-carrying inner contour and, in the open position, allow for full manual cleaning of all inner surfaces.

Description

[0001] The present invention relates to reusable drinking bottles, in particular those that are intended to be completely manually cleanable and represent a hygienic alternative to conventional bottles that are difficult to clean. State of the art:

[0002] Well-known reusable drinking bottles usually consist of one-piece bodies whose interior is only accessible through the top opening.

[0003] This leads to hard-to-reach areas where moisture, bacteria, biofilm, and residue can accumulate. Even cleaning brushes, beads, or cleaning tablets cannot fully reach these areas.

[0004] Self-cleaning bottles with UV technology do remove germs, but they do not eliminate deposits or moisture in mechanical gaps. Purpose of the invention:

[0005] A reusable drinking bottle should be provided that allows all internal surfaces to be fully accessed, enabling hygienic, mechanical cleaning without hidden cavities.

[0006] The bottle should also be leak-proof, robust, suitable for everyday use, drop-proof, and variable in its external shape and choice of material. Solution to the problem:

[0007] The problem is solved by a reusable drinking bottle consisting of two halves that are completely separable and / or hinged around a vertical axis. When open, all interior surfaces are exposed and can be manually cleaned and dried. When closed, the halves form a continuous, liquid-conducting inner contour. The lid and base can each be attached separately.

[0008] They can be attached via bayonet, swivel, clip or plug-in mechanisms, designed to be fully accessible and cleanable without any hidden gaps.

[0009] No internal threads are required. The two halves can be held securely together using an optional top ring, side locks, clips, or other fasteners.

[0010] The sealing surfaces are designed so that they have no internal gaps or moisture-prone cavities. Advantages of the invention:

[0011] Fully open the reusable drinking bottle for mechanical cleaning of all surfaces.

[0012] No hidden cavities, no critical moisture areas.

[0013] Quick drying due to complete accessibility. Modular:

[0014] Suitable for PP versions, stainless steel versions or hybrid versions.

[0015] Compatible with various form factors (sports bottle, thermos bottle, standard shape).

[0016] Robust locking mechanism, suitable for drop-resistant applications. More hygienic than conventional reusable drinking bottles and more sustainable than disposable containers. Examples of implementation:

[0017] A preferred embodiment shows two half-shells connected by external hinges and which can be opened completely by 180 degrees.

[0018] An optional upper ring stabilizes the structure when closed.

[0019] The lid and base are attached using an open bayonet fitting or snap-fit ​​mechanism. The sealing surfaces are smoothly formed and fully accessible manually. Variants include designs without a fixed upper ring, in which the two halves are primarily stabilized by locking points and material rigidity. The invention also includes sports bottle attachments and different external silhouettes, as long as the basic principle of the fully opening two halves is retained. Concluding remark:

[0020] The invention is not limited to the examples shown.

[0021] Deviations in shape, material, locking mechanism or external design that do not change the basic technical principle are also covered by the scope of protection of the invention.
