Description

Drinking tube

Technical Field

The present invention relates to a drinking tube which can be composed of two channels and which can be used several times.

Background

The precondition for multiple use is that the interior of the drinking tube can also be cleaned.

The process of passing a small brush through a drinking tube for cleaning the same is known from US 2017/02 168 90 A1 and US 6 039 490C. This technique of cleaning drinking tubes is complex and very uneconomical in view of the price of the drinking tubes.

In order to obtain a drinking tube usable in a dishwasher, a drinking tube has been developed which consists of two channels which can be connected one inside the other to form a tube for drinking and which can be separated from each other for cleaning.

KR 10 2018 000 133 1A thus describes a drinking tube in which two channels each have separately arranged guides (e.g. dovetail guides) in the edge region, which can be pushed one inside the other to form a closed tube.

The cylindrical drinking tube described in US2019/003 80 A1, in which the edge regions of the two channels each overlap and lie one above the other after being pushed together, is technically easier to produce.

This is provided that the cross section of at least one channel has a sleeve cross section of more than 180 °.

Disclosure of Invention

The object of the present invention is to ensure a closed cross section of a drinking tube safely and cheaply when two channels are connected.

This object is achieved by means of the features of the present invention.

For drinking tubes consisting of two channels which form a closed cross section when connected to one another, wherein the edge regions overlap and lie one above the other in a sealing manner and/or interlock with one another, it is provided according to the invention that the channels are each formed symmetrically with respect to a common axis of symmetry, wherein

a) The height (h) of the channel relative to the symmetry axis is smaller than the width (b) and/or

b) The cross-section of the inner channel is equal to or slightly larger than the cross-section of the outer channel, so that there is tension between these channels one inside the other.

The channel cross-section can be made oval, arcuate, polygonal, circular and/or trapezoidal. In particular special cases, the channels can also be formed as strips.

The symmetry axis is a line perpendicular to the longitudinal direction of the drinking tube.

The two channels are connected by pushing one inside the other or inserting one inside the other.

One pushed inside the other means that one end of the channel is introduced into the end of the other channel and then the channels are displaced relative to each other in the longitudinal direction of the drinking tube by the force of the force. This technique is used with solid channel materials such as steel, stainless steel or solid plastics.

When inserted one inside the other, the channels with open sides are placed one above the other and pressed one inside the other by the action of a force transverse to the longitudinal direction of the drinking tube. For this purpose, at least one channel must be composed of a highly flexible material (e.g. silicon), which then expands as one is inserted inside the other and at least creates a form fit with the other channel.

According to the invention, it is also provided that the two channels consist of a highly flexible material.

The thickness of the channel advantageously allows for elastic deformation of at least the inner channel when the channel is pushed one inside the other or inserted one inside the other under the force of a human hand.

Due to the absence of a circular cross-section design, parallel running guiding edges or guiding arcs are formed in the longitudinal direction of the channels, which advantageously explicitly excludes the possibility of the channels being twisted relative to each other. The result of this is that the width of the overlapping edge region remains constant over the channel length and thus the cross section remains constant closed and sealed on both sides.

In a first embodiment, at least in the case of the outer channel, the edge region is curled inwards into the channel such that it grips the edge region of the inner channel.

In another embodiment, the edge regions of the two channels are made to curl inwardly such that the edge region of the outer channel grips the edge region of the inner channel and the edge region of the inner channel is in direct contact with the outer channel in the area of the outer channel that is not curled.

As a special case of both embodiments, a strip is provided in which the internal channel is made with or without a crimp. A strip is understood to be a strip having a flat surface or a slightly curved surface.

Crimping in the sense used herein means that the outer longitudinal portion of the edge region of the channel is bent a certain amount. This can be achieved at an angle with a small bending radius or in the form of an arc.

Instead of a curl, the channel can also follow only an oval shape in cross section.

It is crucial that no additional guides are arranged on the channel, but that these guides are only produced by the geometry of the channel. This greatly reduces costs, simplifies handling, prevents wear, and is hygienic, such as with the cited KR 10 2018 000 133 1A (where residues of beverage components may still collect in the dovetail guide).

In order to produce a pleasant drinking sensation when using the drinking tube, the channel edges should be formed such that they are rounded at least in the case of the outer channel.

In order to ensure that the connected channels are impermeable, it is advantageous that there is a non-form-and/or frictional engagement between the channels (which are pushed one inside the other or inserted one inside the other) that can be overcome by manual force in order to separate the channels.

The force applied in order to pull the channels pushed one inside the other should be between 1 and 50N, preferably between 8 and 20N.

When using a highly flexible material, the two channels can be pulled away from each other in the same way as banana peels.

Another configuration provides: the combination of the solid channel and the channel made of a highly flexible material or the combination of the channels made of a highly flexible material is provided as a curved drinking tube.

By arc-shaped is meant that the channels that are joined together have a curvature over the entire channel length or only in a certain part, preferably in the last third before the drinking opening.

The channels made of solid material are pre-bent or the channels made of highly flexible material, respectively, and the second channels are in each case at least shape-adapted when the channels are inserted one inside the other.

The adaptive channel is preferably formed as a strip, since in this way it has the lowest moment of resistance and, therefore, the connection remains impermeable over the entire length of the channel.

In addition to the advantages already indicated, the drinking tube according to the invention having a height (h) smaller than the width (b) has the further advantage that:

the passage opening is larger than in the case of a cylindrical passage, which makes cleaning easier,

the attack surface of the human hand is greater when pushing open the channel, which aids the process and renders the deployment of additional grips as in US2019/003 80 58al superfluous,

the outer surface of the outer channel is larger, so that the corresponding advertisement can be applied more efficiently,

the drinking tube can also be bent without becoming impermeable if both channels are made of a highly flexible material.

Detailed Description

Fig. 1 shows a drinking tube with two channels 2,3 which are pushed one inside the other in order to form a drinking tube 1 with a circular cross section.

The cross section of the inner channel 3 is equal to or slightly larger than the cross section of the outer channel 2, so that there is tension between the channels 2,3 one inside the other.

The problem with this embodiment is to achieve the depicted ideal state, i.e. the overlap area is as constant as possible with respect to the length of the drinking tube 1. It may be helpful to display a marker of the correct position.

This problem does not exist in the case of the further depicted solutions, because due to their geometry they guarantee an accurate positioning of the channels 2,3 with respect to each other. In the case of such a drinking tube 1 consisting of two channels 2,3 which form a closed cross section when pushed one inside the other, wherein the edge regions 4 overlap and lie one above the other in a sealed manner or interlock with each other, the channels 2,3 are each formed symmetrically with respect to a common axis of symmetry 5, wherein the height (h) of the channels 2,3 with respect to the axis of symmetry 5 is smaller than the width (b).

Fig. 2 shows an embodiment having an elliptical shape in four views (including one view in cross-section). This embodiment also proves itself well in the case of highly flexible channel materials.

In the case of both channels 2,3, the channel edges 7 are formed such that they are rounded.

In the embodiment according to fig. 3, in the case of the outer channel 2, the edge region 4 curls inwards into the channel 2, so that said edge region 4 grips the edge region 4 of the inner channel 3.

In the embodiment depicted in fig. 4, the edge regions 4 of the two channels 2,3 are made such that they curl inwards, such that the edge region 4 of the outer channel 2 grips the edge region 4 of the inner channel 3, and the edge region 4 of the inner channel 3 is in direct contact with the outer channel 2 in the area of the outer channel 2 which is not curled.

During crimping, as can be clearly seen from the depiction, the outer longitudinal portions of the edge regions 4 of the channels 2,3 are bent a certain amount. This can be achieved at an angle with a small bending radius, as depicted. If the bending radius is large and has the form of an arc, the cross section approximates an oval form.

The special case of the drinking tube 1 depicted in fig. 3 and 4 provides that the internal channel 3 is made as a strip with or without a curl. This is illustrated by fig. 5 with curved outer channels 2 and fig. 6 with trapezoidal outer channels 2.

Fig. 7 shows a drinking tube 1 in which the outer channel 2 consists of stainless steel and the inner channel 3 consists of a highly flexible material, such as silicon. The channels 2,3 are joined together by inserting one inside the other and separated by pulling out the inner channel 3, as depicted.

In both views of fig. 8a curved drinking tube 1 is depicted. The outer channel 2 here too consists of stainless steel. The outer channel is pre-curved in the upper third of the front of the drinking orifice. The internal channel is here a strip of highly flexible material.

The channels 2,3 are joined together by inserting one inside the other and separated by pulling out the inner channel 3. The advantage of using strips as the inner channel 3 is that the strips have the lowest moment of resistance, and when the channels are inserted one inside the other, the strips follow the outer channel 2 and rest in a sealing manner on the crimped region 6 of said outer channel.

Fig. 9 shows a further advantageous cross section of the channels that are joined together: square, hexagonal and triangular, in each case coiled.

Due to the selected geometry of the height (h) and width (b), the curl or arc becomes a guide for the outer channel 2 when the channels 2,3 are pushed together.

This ensures a constant overlap area over the length of the drinking tube 1. The geometry selected and the materials used can also allow the drinking tube 1 to bend or the drinking tube 1 to bend during drinking.

Finally, reference is made to an advantageous configuration in which the channel is formed at the end in the manner of a scoop. Thus, the drinking tube also serves as a scoop. The scoop-like formation is preferably realized at a channel consisting of a solid material.
