Description

The utility model relates to multi-chamber deformable packaging means for storing pasty or semi-liquid substances, gels and is used for toothpastes.

Multicamera tubes (tubes) are widely known in the art for distributing multicolor toothpaste, which is two or more products having the same or similar characteristics of their flows. Typically, such tubes are an elastic deformable container made of an outer tube and an inner tube articulated with it, with one of the products in the inner tube and the other in the space between the inner and outer tubes, the neck of the outer tube includes means for fixing inner and outer tubes between each other and is a complex structure for the simultaneous distribution of two products (RU 2253602 C2, 06/10/2005).

The disadvantages of tubes of this design are their complexity and the need for additional efforts when squeezing substances from the tube.

Also known are multi-chamber tubes consisting of elastic outer containers and inner bags with a composition in which the presence of the outer container is determined by the need to maintain the shape of the tube when the inner bag is empty and deformed, while the lid of the tube has a ventilation hole to equalize the pressure in the space between the outer container and an inner bag through which air escapes from the space between the container and the bag (US 6959840 A, 11/01/2005; SU 1805893 A3, 03/30/1993).

The main disadvantage of these tubes is the inconvenience of use, associated with the need to create additional effort to etch excess air from the space between the outer container and the inner bag, as well as the inability to uniformly empty the inner bag.

To enable even emptying of the tubes, some manufacturers make the outer container of the tube transparent or translucent, which makes the inner container with the substance dispensed more accessible to users (JP 8164954 A, 06/25/1996).

However, this does not solve the problem with the uniform distribution of the substance from the tubes, due to the different distribution of the pressure on the walls of the tubes and the different flow rates of the toothpaste products, as well as the need for additional efforts when squeezing the substances out of the tube.

The problem the utility model aims to solve is to create a multi-chamber tube devoid of these drawbacks.

When solving this problem, a technical result is achieved, which consists in increasing the contact area when squeezing pasty or semi-liquid substances from a multi-case tube, which leads to a decrease in the forces when squeezing substances, without complicating the design of the device.

The specified technical result is achieved in that the multi-chamber tube contains an inner chamber for the starting substance, one end of which is closed, and on the other there is a neck (shoulder) with an outlet for the outlet of the substance, and the outer and inner chambers connected to the neck (shoulder) so that between the inner and outer chambers, a hermetically sealed space is formed, filled with a gel or other liquid, or another transparent polymer mass (for example, silicone).

In a preferred embodiment, the outer chamber is made of a transparent or translucent material. Hereinafter, the term translucent material refers to a material with any degree of transparency or having transparent areas.

In this case, a gel or other liquid or another transparent polymer mass (hereinafter gel) filling the space between the inner and outer chambers is also made transparent. Phosphorizing elements or spangles may be added to the gel. Product information is printed on the outer surface of the inner chamber.

An example of a transparent polymer mass is silicone.

The cameras from one end are attached to the neck (shoulder), and from the other end are closed by means of a seam. To the neck (shoulder) of the camera are connected by thermal pressing or gluing.

Light elements can be integrated into the neck to illuminate the gel filling the space between the inner and outer chambers.

The cameras are made of polymer materials. Alternatively, the inner chamber may be made of aluminum or of multilayer polymeric materials.

The multilayer polymer material may consist of an internal moisture-proof layer with a thickness of about 100 microns, a layer that does not allow organic substances to pass through with a thickness of about 25 microns, and an outer protective layer of a thickness of 200 microns or more, made from a mixture of low-pressure polyethylene and high-pressure polyethylene.

The tube contains a cap.

The essence of the utility model is confirmed by the drawing, which shows a multi-chamber tube in a preferred embodiment.

The multi-chamber tube consists of an inner chamber 1 made of a polymeric material or of a multilayer polymeric material, or of aluminum foil, and an outer chamber 2 made of

transparent or translucent plastic, such as PVC (polyvinyl chloride). The diameter of the outer chamber 2 is larger than the diameter of the inner chamber 1. At one end of the inner chamber 1 there is a neck (not shown) with an opening for the exit of toothpaste. An outer chamber 2 is attached to the neck (shoulder) (position 5 in the drawing) by gluing or heat-pressing the end of the outer chamber to the neck (shoulder). On the other hand, both chambers are connected by means of a seam 4 formed by thermal pressing or in another way. Thus, between the cameras formed a hermetically sealed space, which is filled with a transparent gel or other liquid 3.

The presence of a gel or other liquid 3 between the chambers provides an increase in the contact area during deformation of the outer chamber with the inner chamber 1, which leads to a decrease in the forces when squeezing pasty or semi-liquid substances, in our case toothpaste.

To improve visual effects, phosphorizing elements can be added to the gel - dyes containing phosphorizing pigments, which will allow the tube to glow in the dark. In the manufacture of tubes for children's toothpastes, sparkles of the most diverse shapes can be added to the gel, which will lead to increased interest in children in the procedure for brushing their teeth.

A transparent gel or other liquid 3 and a transparent / translucent outer camera 2 allow you to see the outer surface of the opaque inner chamber 1, which can be applied to any, including volumetric or pseudo-volumetric, stereo, vario product information or advertising information.

The neck (shoulder) with a cover can have any geometric shape, be transparent, translucent or colored. Have a threaded connection, a latch, or be fixed in some other way.

The choice of certain materials for the manufacture of the inner chamber is determined by the composition of the substance being distributed.

In the case of using a tube for specialized toothpastes, for example, whitening pastes or tartar pastes containing active substances that can react with some plastics or aluminum, it is advisable to produce an inner chamber from multilayer plastics, the layers of which are not oxidized by contact with active substances , for example, from synthetic organic polymer plastics.

The tube of the proposed design can be used not only for toothpastes, oral care products, but also for any pasty or semi-liquid products, such as cosmetic creams, hair care products, a variety of paints and glues, building pastes, food products (ketchup, mayonnaise, mustard, etc.).
