Abstract

The invention relates to a flexible tubular container (tube) for storing liquid and pasty substances, for the extraction of which said tubular container is subjected to deformation in order to expel the contents of the packaging. The main part of the tube body consists of an external layer and an internal layer, each of which has a line of weakness, wherein the lines of weakness are offset from each other along the axis of the body. The external layer and the internal layer can be separated between the lines of weakness. Such a design makes it possible for the body, once broken open, to be reassembled by inserting part of the internal layer into the external layer in a reattachment region, thus allowing the contents to be preserved from the moment the site of weakness is broken open until the contents of the tube have been completely used.

Description

Tuba

Technical field

The technical solution relates to an elastic tubular container for storing liquid and pasty substances, which is subjected to deformation to extract them to displace the contents of the package.

State of the art

Packages in the form of a tube are known on the website htp: //www.polymery.ru/production.php? Cat_id = ^: 58 & catjparent = 6 & leveT = 2 (accessed 05.15.2018). The tube is a flexible cylinder, one end of which is hermetically closed, and a neck is formed in the other, on which an external thread can be formed. In this case, a cap with a female thread is screwed onto the neck. Also, the neck can be tightly closed by a lid. At the same time, laminate tubes, which consist of several layers, are described on the site.

A disadvantage of the known technical solution is the inability to extract residues of the contents of the tube after the cessation of its displacement by squeezing the walls, since part of it always remains inside and does not exit through the neck when you press the tube.

The closest technical solution (prototype) is a tube according to French patent application FR2697804 A1, publication date 05/13/1994 (pp. 1-4, Figs. 1-6). This tube contains a housing with a bottom, shoulder and neck, as well as a cap. Moreover, the body has a tubular shape, on the one hand it is closed with the formation of the bottom, and on the other hand the body ends with a shoulder passing into the neck. The neck is closed with a cap. At the same time, at least one place of weakened strength is placed on the body. The place of weakened strength is intended for opening the tube and extracting from it residual contents after the cessation of its displacement through the neck by squeezing the walls.

A disadvantage of the known technical solution is the lack of the possibility of retaining residual contents from the moment of opening the place of weakened strength to the full use of the contents of the tube, due to the lack of the possibility of re-closing the tube in place of weakened strength.

The technical result of the proposed technical solution is to increase the efficiency of use of the contents of the tube by ensuring the safety of the contents from the moment of opening along the line of weakened strength to the full use of the contents of the tube.

The specified technical result is achieved due to the fact that in a tube containing a housing with a bottom, a main part, a shoulder and a neck, as well as a cap, the main part having a tubular shape, on the one hand the main part is closed to form a bottom, and on the other hand the main part passes into the shoulder, passing into the neck, which is closed by a cap, the main part is made up of the outer layer and the inner layer, while the first line of weakened strength is made in the inner layer, the second line is made in the outer layer weakened strength, the first line of weakened strength is closed around the imaginary axis of the body, the first line of weakened strength is offset along the imaginary axis of the body relative to the second line of weakened strength, while the outer layer and the inner layer are made with the possibility of separation between the first line of weakened strength and the second line of weakened strength, in the first particular case, the first line of weakened strength and the second line of weakened strength are made in the form of a set of recesses, in the second in the particular case, the first line of weakened strength and the second line of weakened strength are made in the form of a set of holes, in the third particular case the first line of weakened strength and the second line of weakened strength are made in the form of a set of slots, in the fourth particular case the second line of weakened strength is closed, in the fifth In the particular case, the first line of weakened strength and the second line of weakened strength are located in parallel planes, in the sixth particular case, the first line of weakened strength and second th line weakened strengths are located in parallel planes perpendicular to the imaginary axis of the body.

Disclosure of invention

The drawing shows: cap 1, neck 2, outer layer 3, inner layer 4, shoulder 5, first line of weakened strength 6, second line of weakened strength 7, contact area 8, connecting section 9, bottom 10, body 11, cavity 12.

The tube is a consumer packaging having a predominantly cylindrical body that extrudes the contents. The case is made with a narrow neck, sealed with a cap, a shoulder, a main part and a bottom closed after filling with products (the definition of a tube is given, for example, in GOST 17527-2014 Packaging. Terms and definitions).

The housing 11 of the tube is a tubular product. The housing 11 is made up of at least an outer layer 3 and an inner layer 4. The housing 11 is formed by a neck 2, a shoulder 5, a main body and a bottom 10, smoothly turning into each other and made integral with the formation of a cavity 12 from the side of the inner layer 4 . When the main part is deformed, for example, by pressing it, the volume of the cavity 12 changes.

The main part is part of the outer layer 3 and the inner layer 4 from the shoulder to the bottom. The main part is closed. The outer layer 3 and the inner layer 4 are thin layers of material, i.e. layers having a significantly smaller size in one direction, relative to its size in other directions. The outer layer 3 and the inner layer 4 are located to each other in close proximity, with the possibility of joint exposure to them. In the particular case of the outer layer 3 and the inner layer 4 can be connected to each other on adjacent surfaces with the formation of the connecting sections 9 by means of, for example, an adhesive or temperature exposure. The outer layer 3 and the inner layer 4 are made of material that provides the possibility of deformation of the housing 11 when you click on it. In this case, the outer layer 3 and the inner layer 4 means both a single-layer material, for example, plastic or metal, and a multilayer material or its individual layers, for example, a tube laminate (http://www.tuba.ru/up_tube_abl.html, appeal date 05/15/2018). The inner layer 4 is turned towards the cavity 12. On the inner layer 4, a first line of weakened strength 6 is made, described below. The outer layer 3 is located outside the housing AND, i.e. from the side of the opposite cavity 12 with respect to the inner layer 4. On the outer layer 3 there is a second line of weakened strength 7, described below.

The bottom 10 is the closed end of the tube (housing 11) made, for example, by jointly sealing the edges of the outer layer 3 and the inner layer 4. The bottom 10 is made to prevent leakage of the contents of the cavity 12 from the bottom 10.

The neck 2 is a part of the housing 11 of a cylindrical shape, and the diameter of the neck 2 is significantly less than the diameter of the main part. The neck 2 is located on the opposite side of the housing 11 with respect to the bottom 10. An opening is formed in the neck 2. The imaginary axis of the neck 2 coincides with the imaginary axis of the tube body 1 1 and the imaginary axis of the hole. The neck 2 is made with the possibility of issuing the contents of the cavity 12 through the hole by pressing the body 11 of the tube. On the outside of the neck 2 in a particular case, an external thread can be made. The external thread on the neck 2 is made reciprocal with respect to the internal thread of the cap 1, described below.

The shoulder 5 is a narrowing of the housing 11 from the edge of the main part, opposite the bottom 10, to the neck 2. The shoulder 5 is made in the form of a surface of revolution. A rotation surface is a surface described by the rotation of a plane curve around an axis lying in its plane (definition the surface of rotation is given, for example, on the website htp: //dic.academic.ru/dic.nsf/enc_mathematics/856, date of treatment 05.15.2018).

The cap 1 is a part made with the possibility of clogging the neck 2. The cap 1 can be made, for example, in the form of a truncated cone or cylinder with a recess. A thread is made on the surface of the recess. The external thread on the neck 2 and the internal thread on the cap 1 are made so that the cap 1 can be screwed onto the neck 2. If there is no thread on the neck 2, the cap 1 can be made in the form of a cover, which ensures that the neck 2 is sealed by tightly fitting cap hole 1.

The first line of weakened strength 6 is a line of successively located recesses and / or slots and / or holes in the inner layer 4. The first line of weakened strength 6 is closed around the imaginary axis of the housing 11. The first line of weakened strength 6 is located in a plane intersecting the imaginary axis devices.

The second line of weakened strength 7 is a line of successively located recesses and / or slots and / or holes in the outer layer 3, located in a plane intersecting the imaginary axis of the device. In the particular case of the second line of weakened strength 7 can be made closed.

The first line of weakened strength 6 and the second line of weakened strength 7 are tear lines along which part of the body 11 can be torn off. The first line of weakened strength 6 and the second line of weakened strength 7 are offset from each other along the imaginary axis of the body 1 1. In this case, the outer layer 3 and the inner layer 4 between the first line of weakened strength 6 and the second line of weakened strength 7 form a contact area 8. The contact area 8 is made to ensure separation of the outer layer 3 and the inner layer 4 in violation of the integrity of the first lines of weakened strength 6 and a second line of weakened strength 7, i.e. with the possibility of dividing the housing 1 1 into parts. And also providing the possibility of connecting parts of the housing 11, if necessary, due to the tight fit of the edge of the inner layer 4 into the outer layer 3 at the contact area 8. The first line of weakened strength 6 and the second line of weakened strength 7 are made with the possibility of maintaining the tightness of the housing 11 until the violation the integrity of the first line of weakened strength 6 and the second line of weakened strength 7. In the case of the first line of weakened strength 6 and the second line of weakened strength 7 along a closed line it is possible for the pits to detach part of the entire housing 1 1 completely.

Brief Description of the Drawings

The technical solution is illustrated by the figure, which shows a general view of the tube.

Industrial Applicability and Embodiments

In the case of using the above elements and means, the technical solution is implemented as follows.

The outer layer 3 and the inner layer 4 of the housing 11 can be made of the same materials or different. In the particular case, we consider the embodiment of the outer layer 3 of plastics, and the inner layer 4 of metal, which is not mandatory for this type of device.

In the case of the inner layer 4 of aluminum, according to one of the manufacturing options, first form a tubular product, for example, using a press. This product is a blank for the inner layer 4. Then create the first line of weakened strength 6, for example, grind part of the material or perform slots, holes or recesses sequentially arranged in one line. Using the press also form part of the inner layer 4 in the form of a shoulder 5 and neck 2.

If the outer layer 3 is made of plastic, a blank is formed — a tubular product, for example, by extrusion. Extrusion consists in the continuous extrusion of softened material through an opening of a certain section (the definition of extrusion is given, for example, on the website htp: //dic.academic.ru/dic.nsf/enc3p/334430, accessed 05.15.2018). A second line of weakened strength 7 is formed on the tubular product, for example, part of the material is removed. In this case, the second line of weakened strength 7 is performed at a distance from the neck 2, other than the distance at which the first line of weakened strength 6 is made on the inner layer 4.

The blank of the inner layer 4 is inserted into the blank of the outer layer 3. If necessary, with the formation of the connecting sections due to, for example, applying an adhesive to the surface of the inner layer 4, facing the outer layer 3, with the exception of the contact area between the first line of weakened strength 6 and the second line weakened strength 7. To the workpiece of the outer layer 3 of a tubular shape, the shoulder 5 and the neck 2 of the outer layer 3 are welded, which can be made, for example, by casting.

It is also possible to produce rectangular blanks of the same size for the outer layer 3 and inner layer 4. A first line of weakened strength 6 is made on the rectangular blank of the inner layer 4 and a second line of weakened strength 7 is formed on the rectangular blank of the outer layer 3, removing some of the material of the corresponding layer. In this case, the second line of weakened strength 7 is performed at a distance from the neck 2, different from the distance at which the first line of weakened strength 6 is made on the inner layer 4. Then, these rectangular blanks are laid on top of each other and rolled into an overlap or butt-in-butt pipe . Connect the workpieces at the place of application, for example, by heat sealing, forming a seam.

After the manufacture of the tube by any of the proposed methods or by any other of the methods, an external thread is made on neck 2, if one is provided for and has not been previously manufactured when casting neck 2 with shoulder 5.

A cap 1 is made, for example, of plastic, by casting. Next, an internal thread is formed, if provided, in the recess of cap 1. Then, the neck 2 is closed with cap 1. An additional sealing of the neck 2 with a film or foil is possible before closing the cap 1. The tube is filled with contents, for example, toothpaste or expensive cosmetic cream. Next, the end of the tube opposite the neck 2 is brewed by heat sealing, forming the bottom 10.

In the process of using the contents of the tube, a certain amount of substance remains inside it, for example, an expensive cosmetic cream that cannot be squeezed out of the tube when the tube material is deformed. In this case, the material of the tube body 11 is torn off along the first line of weakened strength 6 and the second line of weakened strength 7, for example, by twisting and disconnecting the parts of the body 1 1 relative to each other, and by any means remove the remaining contents from the tube. If the first line of weakened strength 6 and the second line of weakened strength 7 lie in a plane perpendicular to the imaginary axis of the housing 11, then the length of the tear line is the smallest, which allows the fastest and least energy-intensive separation of part of the housing 1 1. Thus, for effective extracting the contents of the tube does not necessarily cut it, but you can tear off part of it along the first line of weakened strength 6 and the second line of weakened strength 7.

In the case of only partial use of the remainder of the contents from the cavity 12, the housing 11 can be reconnected by inserting part of the inner layer 4 into the outer layer 4 at the contact area 8, which will ensure the safety of the remains of the contents of the tube until it is fully used. This prevents drying, fermentation, leakage, evaporation, oxidation or other changes in the chemical and physical composition of the residues of the contents of the tube under the influence of environmental factors Wednesday.

Thus, the implementation of the tube in the above manner provides an increase in the efficiency of use of the contents of the tube and prevents the long-term penetration into the tube of what should not get there (primarily oxygen, water, bacteria and light) from the moment of opening the case 11 to the full use of the contents of the tube . This possibility is provided due to the possibility of re-closing the tube by inserting the edge of the inner layer 4 from the side of the first line of weakened strength 6 into the outer layer 3 from the side of the second line of weakened strength 7 in the contact area 8.
