Abstract
Description
State of the art
[0001] Drinking devices marketed under the names "drinking funnel" or "drinking rocket" are known from the prior art. The so-called drinking funnel... It typically consists of a funnel connected to a drinking spout via a flexible hose and is used to quickly and easily pour liquids – especially beer. to consume in large quantities.
[0002] The “Rauschrakete” pursues the same purpose, but is built on the principle of an oversized syringe, in which liquid is pumped towards the drinking opening by manually operating a piston.
[0003] However, the existing designs have significant drawbacks. With a drinking funnel and hose, the liquid is supplied solely by gravity, which necessitates a vertical orientation. This means the drinker can only use the device from the ground, making it inconvenient and inflexible.
[0004] Furthermore, a syringe-like device, marketed under the name "Rauschrakete" (Rausch Rocket), is known from the prior art. This device is essentially designed like an oversized syringe and delivers the liquid towards the drinking opening by manually operating a piston.
[0005] However, this design has significant technical disadvantages: - Filling is cumbersome and requires complete disassembly of the piston each time, leading to increased wear and material fatigue. - The device does not have a mouthpiece with a membrane, so the drinking opening must be manually closed – usually with a finger – during filling. This is unhygienic and user-unfriendly. - A check valve is missing, which prevents a uniform pressure build-up. This leads to uncontrolled fluid flow and makes dosing difficult.
[0006] Furthermore, these devices are often made of simple plastics that are not always shatterproof or food-safe. An ergonomic drinking opening is also not included, which makes them less comfortable for the user. Solution to the task
[0007] The problem is solved by a drinking device that overcomes the disadvantages of both the funnel system and the syringe-like device. The device according to the invention comprises: - a transparent cylindrical body with an ergonomically shaped drinking opening (mouthpiece) at the front, - a laterally positioned filling funnel near the piston, which allows for quick and convenient filling, - a non-return valve in the drinking opening area that prevents backflow of liquid and ensures a uniform pressure build-up, - a piston mechanism at the rear end of the cylinder body, which generates gentle pressure through manual pressing, - as well as a screw cap with grip profile for sealing the piston end.
[0008] The device is made of food-grade materials, such as Tritan or PETG for the cylinder body, PP or silicone for the funnel, and a silicone membrane for the check valve. Advantages of the invention
[0009] The device according to the invention offers the following advantages: - Horizontal and vertical operability, making the application more flexible and comfortable. - Hygienic filling, as the drinking opening remains closed by the non-return valve and no manual sealing is required. - Uniform pressure build-up through the piston mechanism in conjunction with the check valve, which enables controlled fluid delivery. - Easy filling via the side-mounted funnel without disassembling the piston, thus reducing wear. - Ergonomic drinking opening for comfortable use. - Robust and food-safe materials that ensure break resistance and hygiene.
Claims
