Definitions

• the invention relates to a two gutters
• Compositable drinking tube which is reusable.
• Drinking tube can also be cleaned inside.
• drinking tubes were developed, which consist of two gutters, the one to drink into each other
• Tube can be connected and separated from each other for cleaning.
• KR 10 2018 000 133 1 A describes a drinking tube in which the two grooves in the edge region each have separately arranged guides, e.g. Dovetail guides have, which are pushed into each other, so that a closed tube is formed.
• Drinking tubes in which the marginal areas of the two channels overlap one after the other and lie on top of each other. This assumes that at least one channel has a cross-section of more than 180 ° shell cross-section.
• the object of the invention is to connect two
• the height (h) of the grooves relative to the axis of symmetry is smaller than the width (b) and / or b) the cross section of the inner groove is the same or slightly larger than the cross section the outer gutter, so that there is tension between the gutters.
• the channel cross sections may be elliptical, arcuate, polygonal, circular and / or trapezoidal.
• a gutter may be formed as a bar.
• Symmetry axis is a perpendicular to Trinkrschreibchen- longitudinal direction.
• the two channels are connected by
• Pushing each other means that one end of a groove is introduced into the end of the other groove and then a displacement of the grooves is made by a force effect in drinking tube longitudinal direction.
• This technique is used for solid channel materials such as steel, stainless steel or solid plastic.
• both channels consist of a highly flexible material.
• the thickness of the grooves allows one
• the edge regions are bent inwardly into the groove at least in the outer channel, so that these edge regions surround the edge regions of the inner groove.
• edge regions of both grooves are executed inwardly cranked, so that the
• Edge regions of the outer groove surround the edge regions of the inner groove and abut the edge regions of the inner groove up to the non-cranked region of the outer groove at this.
• the inner channel is designed as a bar with or without cranks.
• a bar is understood to be such with flat surfaces or slightly curved surfaces.
• Crowning in the sense used here means that an outer longitudinal section of the edge region of the gutters around a
• the grooves in the cross section can follow only one elliptical shape.
• the gutter edges should be rounded at least in the outer gutter.
• Nested grooves should be between 1 and 50 N, preferably between 8 and 20 N.
• the two gutters can be pulled off each other similar to removing a banana skin.
• Troughs over the entire gutter length have a curvature or only in a certain section, preferably in the last third before the drinking opening.
• the groove made of the solid material or a groove made of a highly flexible material are pre-bent, while the second groove in each case adapts when nesting at least positively.
• this adapting channel is designed as a strip, since it thus has the least resistance moment and thus the connection over the entire
• drinking tubes according to the invention having a smaller height (h) than width (b) further advantages: the gutter opening is larger than in the case of cylindrical gutters, which makes cleaning easier,
• Pushing apart is greater, which facilitates this process and makes the use of additional handles as in US 2019/003 80 58 Al superfluous,
• the outer surface of the outer gutter is larger, so that appropriate advertising can be applied more effectively,
• the drinking tubes can also bend without leaking.

• Fig. 2 shows an embodiment with an elliptical shape in four views, including one in cross section. This version has also proven itself in highly flexible gutter materials.
• the gutter edges 7 are rounded.
• edge regions 4 are bent inwardly into the channel 2 in the outer channel 2, so that these edge regions 4 surround the edge regions 4 of the inner channel 3.

• an outer longitudinal section of the edge region 4 of the grooves 2, 3 is bent over by a certain amount. This can be done at an angle with a small bending radius as shown. If the bending radius is larger and has the shape of an arc, the cross section approaches an elliptical shape.
• FIGS. 3 and 4 A special case shown in FIGS. 3 and 4
• Fig. Figure 7 shows a drinking tube 1 in which the outer channel 2 is made of stainless steel and the inner channel 3 is made of a highly flexible material such as silicone. The joining of the grooves 2, 3 takes place by nesting and the separation by removing the inner groove 3 as shown.

• Fig. 9 shows further advantageous cross sections
• cranks or arches Due to the selected geometry of height (h) and width (b), the cranks or arches become guides for the outer channel 2 when the channels 2, 3 are pushed together. This guarantees a constant overlap area over the length of the drinking tube 1.

• Drinking tube 1 or the drinking tubes 1 can be bent while drinking.
• the drinking tube thus also receives a spoon function.
