Description

Technical field

The utility model relates to the field of light industry, in particular to means for drinking drinks, characterized by the possibility of flavoring the drink in the process of its consumption.

State of the art

The prior art disclosed in the patent of the Russian Federation No. 151320 of 08/05/2014, a tube for flavoring a beverage containing a flavoring concentrate in the form of granules between the filters at the ends of the tube, each filter consists of four channels separated from each other by three heat-welded seams . This known device is a prototype of the claimed tubule for flavoring a drink.

A disadvantage of the known tube for flavoring a beverage is that it does not determine the effect on the strength of the seams of the filter shaping process during thermal welding of opposite sections of the tube wall with a heated tool, leading to deformation of the tube wall in the weld zone.

Utility Model Disclosure

The utility model solves the problem of hardening the filter tubes for flavoring the drink and ensures the achievement of the technical result, which consists in increasing the strength of the seams of the filter tubes for flavoring the drink, including by reducing the tensile strength of the joints transmitted from adjacent sections of the wall of the tube, which are the walls of the filter channels.

The specified technical result is achieved in a tube for flavoring a beverage containing a flavoring concentrate in the form of granules between filters at the ends of a polypropylene tube, consisting of four longitudinal channels separated from each other by three seams, thermally welded while the thickness of the seams, as a result of exposure to heated tools , pressing opposite sides of the wall to each other when performing thermal welding, is from 50% to 75% of the double wall thickness of the tube made of olipropylene, and the wall of the tube is thinned on adjacent to the seams sections of the outer side of the wall of the tube. The following parameters are possible: the outer diameter of the tube is from 8.2 mm to 9.2 mm, the wall thickness of the tube is 0.20 mm, each filter consists of four channels separated by three seams, the thickness of each seam is from 0.20 mm up to 0.30 mm, with a seam width from 0.80 mm to 1.2 mm and a seam length from 2.40 mm to 3.40 mm, and the wall thickness of the tube at the junction with the seam from 0.1 mm to 0, 18 mm

Seams can be made in the form of longitudinal rectangular strips, in particular, with rounded corners.

The outer diameter of the tube may be 8.7 mm.

The diameter of the spherical granules of the flavoring concentrate can be from 1 mm and higher, usually no more than 2.5 mm, the seams separating the channels in the filters can be spaced from each other and from the edge of the tube with the same interval, forming channels with a minimum transverse size of 0, 4 mm to 0.8 mm.

Brief Description of the Drawings

The essence of the utility model is illustrated by drawings, where:

in FIG. 1 shows a general view of a tube for flavoring a beverage;

in FIG. 2 shows an enlarged fragment of a general view of a beverage aroma tube including a filter.

in FIG. 3 shows an even larger enlarged cross-section of a fragment of a general view of the tube shown in FIG. 2.

Utility Model Implementation

In FIG. 1 and FIG. 2 shows a tube 1 and filters 2 formed by seams 3 of a rectangular shape at the ends of the tube. Granules of flavoring concentrate are not shown and are located inside the tube 1 between the filters 2.

In FIG. 3 shows a cross section of the filter in the transverse direction. As a result of thermal welding of the opposite sides of the tube wall pressed against each other by a heated tool, channels 4 are formed. At the same time, the thickness of the welded opposite sections of the tube wall in the seams 3 as a result of the action of the heated tool decreased significantly. The thickness of the wall 5 also significantly decreased as a result of exposure to a heated tool in places 6 adjoining the wall 5 to the seams 3.

The strength of the seams obtained by thermal welding depends not only on the area that the seams occupy, but also on the quality of welding of opposite sections of the tube wall. Since the wall sections melted by the heated tool must be pressed, they become thinner. To prevent the destruction of the wall of the tube, use the limiters of the heated instruments.

In FIG. 3 the dotted line shows the location of the heated tools 7 and 8 relative to the weld 3 formed by them. It has been experimentally established that the thickness of the weld should be from 50% to 75% of the double wall thickness 5 of the tube, which ensures a reliable connection of the welded sections. The wall also thins out in sections 6 adjacent to the seams on the outside of the walls 5, since the heated tools 7 and 8 act, as can be seen in FIG. 3, to the corresponding parts of the walls.

It should be noted that since the opposite sides of the tube wall are partially welded, the welded wall sections (seams) alternate with the channel walls acting on the sections connected by welding. At the same time, the forces applied to the seams are aimed at breaking the sections connected by welding. However, due to the thinning of the wall on the outside of the sections 6 adjacent to the seams 3, the tensile strength of the seams 3 transmitted from the adjacent sections of the wall 5, which are the walls of the channels 4, decreases. It has been experimentally established that if the wall thickness of the tube at the junction from 0.1 mm to 0.18 mm, this contributes to a lower load on the seams when using the duct. This thinning of the wall on the outer side of sections 6 contributes, at the same time, to the bending of the wall of the tube in sections 6 adjacent to the seams 3, and the formation of channels 4 of an oval shape in cross section.

Tests were carried out for the strength of the joints in a tube with an external diameter of 8.7 mm and a wall thickness of 0.20 mm. During testing, the filter of the tube was subjected to a load exceeding the maximum load created by using the tube and the corresponding pressure drop at the inlet and outlet of the filter equal to 1 atmosphere. To test the strength of the seams, tubes were used, at one end of which a filter was made with seams, and through the other open end, water was supplied for 1 minute under a pressure of 1 atmosphere. Thus, the pressure acting on the seams in the tube was exceeded, which was higher than the pressure in the tube when liquid was sucked from it by the mouth. During testing, the value of the parameters of the joints of the tube was changed in increments of 0.1 mm. The values of the parameters and the quality of the seams were checked using an optical microscope.

Tests allowed us to determine the declared parameters of the seams and the values of the wall thickness of the tube at the junction with the seam.

By calculation, the experimental results confirming the strength of the joints with the stated parameters are extrapolated to tubes with a diameter of 8.2 mm to 9.2 mm.
