Definitions
- the invention is in the field of the packaging industry and relates to a closure unit and a method for its production according to the preambles of the corresponding independent claims.
- closure units preferably made of plastic, consisting of a pouring part with a pouring opening and a closing part which closes the pouring opening of the pouring part, are used in an opening of the container.
- closure unit is disclosed, for example, in Swiss patent application No. 2740/91.
- closure units consist of a plastic which is said to have cheap properties which are favorable for the manufacture of the closure unit. This is so that the production can be carried out with tools that enable a large output. This is to ensure that the closure unit increases the price of the container as little as possible and that the container with the closure unit appears attractive to the user from as many points of view as possible. Now it can happen that the goods in the container are additionally protected against influences from the environment should be so that it remains durable for a long time. Such influences which can adversely change the goods are, for example, the moisture in the environment, including the ambient air, and light or other types of radiation.
- gases such as exhaust gases which are mixed with the ambient air can adversely affect foods in such containers and, for example ⁇ oxidize the vitamins contained therein or change the taste of such foods.
- gases such as exhaust gases which are mixed with the ambient air can adversely affect foods in such containers and, for example ⁇ oxidize the vitamins contained therein or change the taste of such foods.
- this film has to be removed or perforated and that afterwards it can no longer fulfill the function originally intended for it. That for example, it is no longer gas-tight or no longer opaque. It can no longer fulfill its function even if a closure part of the closure unit closes the pouring opening again, because when the closure part is closed, the film is not returned to its original state. Seen as a whole, the package as a whole has lost part of its properties as a result of the first opening of the closure unit, as is the case for a package without a closure unit and is also accepted because it seems to be unavoidable here.
- the invention as characterized in the claims, now solves the problem of creating a closure unit for a container with which the original properties of the container, which are used to protect the goods are essential, practically unabated, even after the closure unit has been opened several times.
- the invention solves the problem of creating a closure unit for a container which, in the closed state, is substantially more gas-tight and / or radiation-impermeable even when the closure has already been opened.
- one or more coatings are applied together on the inside of the closure unit, on the outside or on the inside and outside. These coatings adhere to the pouring part and on the closure part and bridge a separation point between the pouring part and the closure part as a thin membrane or at least partially fill them.
- the coating is only interrupted at this comparatively very small separation point and is not restored after the closure.
- the advantages achieved by the invention can be seen, in particular, in the fact that the requirements placed on the container to protect the goods are retained even if further functions are performed with the container for which it is intended.
- the package performs several functions in relation to the good that it is to contain, such as, for example, protecting the good against external influences, handling the good, storing the good, etc.
- one of these functions also becomes not impaired if or because one performs another of the functions provided.
- each function is retained independently of the other functions or properties.
- This is in complete contrast to known containers, in which the exercise of one function has the other functions. inevitably impaired. For example, handling the goods, such as partially removing them from the known container, has a lasting effect on the protective function of the container.
- Another advantage of the solution according to the invention is that the application of the coatings can be integrated into the manufacturing process of the closure unit. A finished closure unit provided with all the desired properties can thus be produced and later attached to a container.
- the invention further makes it possible to adapt the properties of the container and the closure unit together to the most varied of conditions. It is thus possible to provide a first coating which optimally fulfills a first condition (for example sealing against light or barrier against the exchange of oxygen). However, if this coating is mechanically vulnerable, for example due to granular material in the container, a further coating can be provided which protects the first coating against mechanical damage. A third coating can be provided, which has further supplementary properties, etc.
- Properties or functions can thus be assigned to the individual coatings which they optimally fulfill and the missing properties can be assigned by additional. Layers are added that optimally fulfill these additional properties. This means that many conditions that one would like to place on the container and the closure unit can be optimally fulfilled.
- properties that are possibly reduced can, as already mentioned, be at least partially compensated for by other measures. Even if this should not always be possible, the areas which, if at all, do not fully meet the above-mentioned properties are, according to the invention, vanishingly small against the inner surface of the container.
- FIG. 1 shows a container with a closure unit in a perspective view
- Figure 2 shows a closure unit in section.
- Figure 1 shows a closure unit 1 which is inserted into a container 2 made of cardboard.
- the closure unit 1 consists of a pouring part 3, which protrudes from a surface 4 of the container 2, and. a closure part
- the closure part 5 and the pouring part 3 are not releasably connected to one another via a hinge 6.
- the surface 4 has an opening 7, into which the closure unit 1 is inserted, and in this example the closure unit must be pushed through the opening 7 from the inside of the container before it is attached to the wall 4, for example by an ultrasonic welding .
- FIG. 2 shows a section through the closure unit 1 from FIG. 1. This shows the pouring part 3, the closure part 5 and a hinge
- the embodiment shown here also has various details which are not essential to the invention, but which are shown in order to show a fully functional closure unit.
- a detail is, for example, a predetermined breaking point 11, which is destroyed when it is opened for the first time and forms the actual separation point between the pouring part 3 and the closing part 5.
- this closure unit also has sealing surfaces 8 which lie between the pouring part 3 and the closure part 5 where these two parts overlap one another.
- a foot 9 is also visible here, which is fastened to the pouring part 3 and which forms a surface 10 via which the closure unit 1 can be fastened in the wall 4 (FIG. 1).
- a fastener type of supply can be provided, for example, gluing or welding.
- a first coating 12 can also be seen, which is applied here only in the right half of the closure unit on the inside 13 thereof and which is covered by a further coating 14.
- An outer coating 19 can also be seen, which extends here both over the closure part 5 and over the pouring part 3.
- the coating 12, 14 is destroyed in the region of the predetermined breaking point 11, which, shown in FIG. 1, roughly follows line 15.
- the outer coating 19, however, is torn or interrupted in the area of a point 20.
- the exemplary construction of the closure unit 1 shown here ensures, however, that the effect of this destruction remains extremely small, because the closure part 5 encloses the pouring part 3 in the area of the sealing surfaces 8 in such a tight manner that the closure unit 1 also thereby without coating is tight against the passage of gas or liquid.
- baffles which are denoted by 16 and 17 and form additional corners and areas which, for example, improve the seal.
- the coating 12, 14 is intended to improve the closure unit 1 against the diffusion of gas or liquid through its walls, this effect is retained by the intact coating 12, 14 over the entire remaining inner surface 13.
- the material thickness is at least doubled, which means that diffusion is also greatly inhibited by the increased material thickness where the coating is damaged.
- the same effect also results in the area of the separation point 11 with regard to radiation, diffusion, etc.
- an inner and outer coating is required Particularly effective, since both act here over a large area and do not have their separation point 11, 20 at the same location, so that one coating covers the separation point of the other coating.
- Such a closure unit 1 is attached to the container 2 via the foot 9.
- the area 18 must be welded through the coating, which can destroy it there.
- the material from which the base 9 and the wall 4 are made is changed, for example compressed, in this area 18, so that the lost effect of the coating is compensated for by this effect. If this is not the case, it can be glued, for example, so that the coating remains intact. Welding interrupts the coating, while gluing bridges the coating.
- the coatings 12 can consist of a wide variety of materials. Coatings made from mineral substances are particularly cheap. This creates a glass-like coating that is chemically neutral and can therefore come into contact with a wide variety of substances without reacting. Glass-like coatings are also very suitable to avoid undesired gas exchange. In order to protect the material against the influence of radiation or of electrical and magnetic fields, coatings made of metallic materials are well suited. Plastic coatings can be provided as a further coating 14, which, for example, offer protection against thermal and mechanical influences. For example, the properties of the metallic coating, which can be relatively reliable, can be supplemented by also giving them the lack of invulnerability.
- the coatings can be provided on the inside of the closure unit, ie on the inner surface 13, but also on the outside on the outer surface or at both points.
- the coatings have a thickness which ranges from a few angstroms to a few tenths of a millimeter, depending on the type of coating and the task which it is intended to perform.
- the closure unit 1 is first manufactured, for example, by casting in a manner known per se.
- the closure unit is then provided with the first coating in a further device known per se. This is preferably done with the closure part closed.
- a further coating is then applied in the same or in another device.
- the equipment used depends on the type and material of the coating.
- a coating made of aluminum for example, is provided, this is done in a device for evaporating aluminum.
- Coatings based on silicone oxides, which are relatively hard, can be produced by application in a plasma. This is very advantageous because this process does not have to take place at high temperatures.
- plastic coatings can also be easily sprayed on.
