Description

The invention relates to flexible packaging elements of unlimited length, made of non-metallic flexible materials used to bind or support products.

Known tape metal belt for strapping materials [1], including a locking connection formed by connecting the ends of the lap. The keyhole connection consists of the main and additional cuts, which are made in the form of curly cuts, each of which consists of sections located sequentially at an angle to one another. The disadvantage of this design is that the castle sections at the ends of the interaction region of the covering part are subject to the risk of destruction, since the tensile force exerted on the tape belt in the longitudinal direction acts to this extent to the maximum extent.

Known tape for strapping [2], containing a number of sections with a single cell, each of which includes a small rectangular hole and one or more locking parts. In order to form a closed loop, a section with a unit cell at the first end is inserted into the hole of a predetermined unit cell, and the first end of the tape is tightly drawn, as a result of which the strapping tape with its locking part passes into the hole like a ratchet. The disadvantage of the described design is that for tight tying requires a large tensile force and rotation of the first end of the tape for pulling through the hole by 90 degrees with subsequent rotation to its original position.

The closest technical solution is the strapping tape [3], made as a single unit of a semi-rigid elastic resiliently bending material consisting of repeating single adhesion elements in the form of holes located in series along the belt and protruding to the sides of the locking parts. Tying is carried out by pulling the end of the tape into the selected hole and

by stretching it in the longitudinal direction to impart a packing density, after which the remaining unused end of the tape is cut off.

The disadvantages of the described construction are the unreliability of the mount, due to the fact that the clutch is carried out in only one link and depends entirely on the strength of the material of the tape, as well as the impossibility of uncoupling the tape without damaging it (cutting), i.e. in single use.

The objective of the proposed utility model is to create a design of a flexible tape device of the lock type, which has high reliability of fastening of products, regardless of their size, reducing the cost of packaging means due to the possibility of their multiple use.

The tasks are solved by the fact that in a flexible tape device of the castle type made of semi-rigid elastic elastically bending material and consisting of repeating single clutch elements, each clutch element is a protrusion expanding from the outside and a notch tapering from the outside, having the same shape and the size coaxially located perpendicular to the longitudinal axis on its opposite sides, while in the center of the bottom of the recess in the direction of the longitudinal axis, a cut is made with an opening angle of up to 45 degrees. Depending on the purpose of the flexible tape device and the material from which it is made, the notch can be made in the form of a triangular recess with an angle of up to 45 degrees.

The design of the proposed device and the principle of its operation are illustrated by the drawings: Figure 1 - coupling element (possible configurations of protrusions and recesses); Figure 2 - flexible tape device of the lock type in the working position (for example, when tying the product of cylindrical section).

A flexible tape device forms a locking connection when applying tape with overlap clutch elements. The locking connection is carried out by single clutch elements formed by protrusions 1 and recesses 2, identical in shape and size, and located coaxially on opposite sides of the longitudinal axis of the tape perpendicular to it. To ensure reliable adhesion, the outer part of the protrusions is made expandable, and the outer part of the recesses is tapering, while their shape can be any. As an example, figure 1 shows a rounded and trapezoidal shape. A notch 3 with an opening angle of up to 45 degrees is made in the center of the bottom of each recess toward the longitudinal axis, or if the material of the proposed tape device is not flexible enough or has a large thickness for its purpose, a triangular recess 3 with an angle of up to 45 degrees is made instead of the notch.

A flexible tape device of the lock type operates as follows. The packaged product is tightly covered with a full (inner) turn 4 of the flexible tape device (figure 2), applying a longitudinal force to stretch and open the notches in the recesses. On top of the inner turn 4, directly covering the product, the next turn of the tape with clutch elements is wound. Perforations 3 (or triangular recesses 3) made at the bottom of each recess 2 (or triangular recesses 3) facilitate this task and expand the recesses of the inner turn, ensuring that the protrusions of the next turn are precisely inserted into them. The resulting clutch element is depicted in figure 1 (section aa). The number of engagement clutch elements is determined by the requirements for the strength of the package: it can range from several elements to several turns of the tape. The tight placement of the protrusions of each next turn in the recesses of the previous one accordingly increases the reliability and strength of the package. The shape and size of the grooves or triangular recesses made in each recess depend on the width, thickness of the tape and the material from which it is made. The stiffer and less elastic the tape, the deeper the notch and closer to 45 degrees the required opening angle. In wide and thick flexible tape type lock devices for large products, it is advisable to replace the notches with triangular recesses.

At the end of the packaging, the remaining end of the tape is cut off. If necessary, unpacking is possible (by conventional unwinding in the opposite direction) without damaging the proposed device and its repeated use. The proposed design of a flexible tape device of the lock type can be used as a shock-absorbing and protective device for delicate products: for this it is enough to increase the height of the protrusions (depth of the recesses) and expand the winding (width of the tape) to the entire product.

Thus, the proposed design of a flexible tape device of the lock type provides a solution to all tasks: it has high reliability due to the possibility of multiple and multi-layer gearing; economical - thanks to the possibility of reuse and wastelessness; multifunctional - can be used not only as a binding and supporting device, but also as a shock-absorbing package.
