Abstract

Drinking tubes, which serve for the removal of liquids from a container (4), characterized in that the Trinkröhrchenwandung (1) consists of two circumferentially interlocking grooves (2, 3), which form such a closed tube profile.

Description

The invention relates to a drinking tube for receiving liquid from a container.

Such drinking tubes - usually provided with a kink - are well known. In Germany alone, more than 40 billion such plastic drinking straws are used annually, mostly as disposable products, so that about 2,500 tons of plastic waste have to be disposed of or pollute the environment.

The use of these drinking tubes as disposable products has a major cause, namely the lack of cleaning options, so that forms very quickly in the drinking tube mold.

From the US 2017/02 168 90 A1 and the US 6 039 490 C it is known to pierce drinking tubes with small brushes to clean them. This technique does not work with kinked drinking tubes and is highly unprofitable in view of drinking tube prices.

Thus, the question of alternatives, one does not want to do without drinking tubes.

The object of the invention is therefore to design drinking tubes so that they are reusable under consideration of the hygienic requirements.

This object is achieved with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

For drinking tubes for the removal of liquids from a container, the invention proposes that the Trinkröhrchenwandung consists of two circumferentially intermeshing grooves that form such a closed tube profile.

Thus, a drinking tube for drinking by the suction of liquid from the container is available, which can be divided after use by pushing apart into two grooves, which then z. B. can be cleaned easily in a dishwasher without hygienic residues are to be feared.

Preferably, the grooves each have a longitudinally slotted cylindrical shape, wherein the opening angle α of the slot can be between 30 ° - 170 °. Preferably, the grooves are longitudinally slit in a quadrant with an opening angle of 90 °. Of course, it is also possible to provide the channels with different opening angle for the slot - it is only necessary that when pushing together a closed Trinkröhrchenwandung can be produced

Further, the outer diameter of the inner channel should be the same or slightly larger than the inner diameter of the outer channel, so that there is a tension between the grooves lying inside each other.

Since the two channels must be pushed together again for further use as a drinking tube, it is advantageous if the thickness of the grooves allows elastic deformation of at least the inner channel during mating of the grooves under the force of the human hand.

A further advantageous embodiment provides that the outer channel has fastening means for arranging a seal for the opening of the container with liquid and / or depots with drugs to be administered when drinking, and / or by a float for the drinking tube in the liquid of the container.

The arrangements mentioned are only an excerpt of what can already be connected to the disposable drinking tube today or connected to the drinking tube. Likewise, holes can be introduced into the gutters to z. B. drag in air while sucking. Also on the end located in the container can attach funds that are beneficial for fluid intake.

However, all of these arrangements should be removable so as not to hinder the cleaning process of the separate gutters.

A further advantageous embodiment provides that the edges are rounded at the ends of the grooves. This facilitates pushing together and increases injuries if the grooves are not pushed together in their length exactly.

Preferably, the channels are made of metal z. B. stainless steel and can be disposed of environmentally friendly then after multiple use.

With the drinking tube according to the invention, the kitchen equipment is extended by a new accessory.

In the drawings, the components and the drinking tube are shown in several views.

• 1 die Rinnen, die das Trinkröhrchen durch Zusammenschieben bilden und
• 2 das zusammengesetzte Trinkröhrchen.

Show it:

• 1 the gutters, which form the drinking tube by pushing together and
• 2 the composite drinking tube.

1 shows two grooves 2 . 3 , which form a drinking tube when pushed together. this shows 2 ,

The two gutters 2 . 3 have a longitudinally slotted cylindrical shape, wherein the slot is within a quadrant x, y and here an angle α of approx. 90 ° occupies.

This geometry is sufficient to have sufficient double walledness in the drinking tube wall 1 to dispose without pushing the gutters together 2 . 3 meticulous to perform meticulously.

The outside diameter of the inside gutter 3 is slightly larger than the inner diameter of the outer channel 2 so that between the troughs 2 , 3 is a voltage.

The thickness of the gutters 2 . 3 leaves an elastic deformation of the inner channel 3 during the mating of the grooves 2, 3 under the force of the human hand too.

Next it is shown that the edges at the ends of the gutters 2 . 3 are rounded.
