EP1222873A1 - Mouthpiece for a drinking tube - Google Patents

Abstract

The mouthpiece (1) made of a rubber-like material, for the drink line of a drink system, has a main section (3) with substantially elliptical hollow cross section accommodating a valve-like element with an automatically closing outlet which, however, is openable by pressure on the mouthpiece.

Description

The present invention relates to a mouthpiece for the Drinking or suction line of a drinking system.

Drinking systems are becoming increasingly common in sports and leisure more appreciated. They are used for hydration when needed, without doing any sporting or other activity must be interrupted.

In today's hydration systems, the mouthpieces consist of essential cylindrical bodies. It has shown, that such bodies are destroyed relatively quickly by use become and therefore have to be replaced.

The object of the present invention was to close a mouthpiece create which is ergonomic compared to the state of the art is more advantageous to use and which one Closure and general properties more durable is.

This task was defined for a mouthpiece of the type mentioned at the beginning Kind according to the invention by the features according to the characterizing part of claim 1 solved.

Particular embodiments of the subject of the invention are defined in the dependent claims.

Thanks to the special shape of the mouthpiece with the striking Bite groove on its free edge creates an optimal Bite surface, which is an ergonomically good position for drinking allowed. Thanks to the advantageous design of the interior optimal fluid passage is guaranteed, since the passage is not completely closed when gritting can be. This configuration also provides a guarantee for an optimal closure of the outlet at rest of the mouthpiece (optimal elastic closure).

The invention is described below with reference to a drawing illustrated embodiment a little closer explained.

The drawing shows a mouthpiece 1 according to the invention Silicon on an enlarged scale (approx. 4x enlarged), consisting of from an essentially elliptical body 3 with a connecting piece 2 for connecting one Drinking line (not shown), which on the nozzle 2 is plugged in or inserted into the passage 2 '.

The passage 2 'of the nozzle 2 leads into a cavity 4 in the base body 3, at its opposite the nozzle 2 At the end of a valve-like outlet 5 (slot) is provided is. Since the mouthpiece is made of rubber-elastic material, the valve-like outlet 5 becomes automatic in the rest position held in the closed position.

Is on the outer surface of the mouthpiece 1 at the outlet end a striking circumferential bite groove 6 is provided. By external pressure on the mouthpiece, especially due to bite on the bite groove 6, the outlet 5 will open and Allow liquid (which via the inlet or suction line into the mouthpiece).

The passage between the connection piece 2 and the valve-like Outlet 5 is essentially cylindrical. The Both side wings 3 ', 3 "of the base body 3 have one thickened wall (see Figure 5). Also are from the end wall 3 "'rang two stop bodies 7, 8 provided against which the thickened wall when gritting the Mouthpiece get to the system before going through this process the passage is completely closed. So that's one ensures maximum fluid absorption (volume).

The thickened wall also ensures that the outlet 5 remains well closed at rest (support elastic properties).

Figure 6 shows a section similar to Figure 5 through a Base body 3 completely filled with its material Side wings 3 ', 3 ". Also with this variant achieved the advantages mentioned above (prevention a complete closure of the passage at the bite and support for the closing force for the outlet opening 5th

Claims (4)

Mouthpiece for the drinking line of a drinking system, characterized by a substantially elliptical basic body made of rubber-like material, which has a connecting piece at one end for connecting the drinking line and whose passage leads into a cavity of the basic body, which has a valve-like, at the other end Has rest position automatically closing outlet, which, however, opens by external pressure on the mouthpiece, a substantially circumferential biting groove being provided on the outer surface of the outlet end of the mouthpiece. Mouthpiece according to claim 1, characterized in that a substantially cylindrical passage is provided for the liquid transport between the inlet of the connecting piece and the valve-like outlet, and that the two side wings of the base body are filled with the material of the base body. Mouthpiece according to claim 1, characterized in that a substantially cylindrical passage is provided for the liquid transport between the inlet of the connecting piece and the valve-like outlet, and that the two side wings of the mouthpiece cavity have a thickened wall, such that opposing wall parts when the Push the mouthpiece against one another directly or via the stop body before the cylindrical passage is completely closed. Mouthpiece according to one of claims 1 to 3, characterized in that it consists of preferably transparent silicone.
