Description

tube package

The invention relates to a tube packaging or tube according to the preamble

Claim 1 or 2.

Tube packaging made of plastic (plastic tubes) are known in different versions and basically consist of a tubular or tubular tube body and a molded part! Tubular shoulder made of plastic, which i.a. forming the tube opening and having a tube opening remote, e.g. flange

Tubenschulterabschnitt used in one of the open ends of the tube body and is connected to this Tubenschulterabschnitt in a suitable manner, for example by welding to the tube body or its wall.

It is also known to perform the wall of the tube body in multiple layers, u.a. with at least one, for example, metallic barrier layer, e.g. against oxygen and with at least one plastic layer. However, an optimal barrier effect is not achievable because of a lack of a barrier layer on the tube shoulder produced as a plastic part. In addition, such plastic tubes are for many products, especially for aggressive, plastic attacking products, e.g. Hair dye not suitable.

The object of the invention is to provide a tube packaging with improved properties. To solve this problem is a tube packaging or tube according to the

Patent claim 1 or 2 is formed. According to one aspect of the invention, the tube body and the tube shoulder with a

Barrier provided, and indeed to achieve a barrier effect and / or to achieve the necessary strength against aggressive products. In a preferred

Embodiment, the barrier layers on the tube body and on the tube shoulder are designed so that these barrier layers not only overlap in the region of the connection between the tube shoulder and tube body, but directly abut each other or connect, so that a continuous total barrier layer from the tube opening to the opposite end of the tube and closed after filling results in tube body end.

The at least one layer designed barrier layer of Tubenschuiter and / or the tube body acts in particular against oxygen and water vapor blocking and looks from a suitable material or material, such as a metallic material, for example Aluminum, and / or aluminum oxide, and / or of an electrically non-conductive material, for example of silicon oxide and / or of EVOH.

According to another aspect of the invention, at least the tube shoulder or the

Tube body internal with an oxygen absorbing or absorbing

Coating, for example with a coating which in a product-neutral matrix, e.g. contains in a plastic matrix a reacting with oxygen and thereby receiving or absorbing filler or additive. Due to the oxygen-absorbing coating, oxygen that is present in the inside of the tube, but also in the product filled with the tube, is removed from the tube and thereby u.a. an impairment of the

Product, in particular a deterioration of the durability and / or quality, and the taste quality of this product by oxygen (oxidation) effectively prevents the (oxygen) in particular when de use or consumption of the in the

Tube packaging bottled product passes with the entering through the tube opening air into the tube interior. In this case, both the tube shoulder and the tube body or its wall are preferably provided with the oxygen-absorbing coating on the inside.

The oxygen-absorbing additive is particularly suitable for base metals in particulate or powder form, e.g. Iron, preferably annealed and / or electrolytically reduced base metals, e.g. Iron, metal halides.

In a preferred embodiment, the oxygen scavenging coating is provided in addition to the barrier layer, so that oxygen that has still passed through the barrier layer or leaks in the barrier layer is also taken up by the oxygen scavenging coating, even before that oxygen becomes in contact with the oxygen scavenging layer

Tube packaging bottled products can react.

For the purposes of the invention, a "tube shoulder" is a molded part made of plastic, which has at least the tube opening which can be closed by a closure cap and forms a closure of the tubular tube-like tube body at one end of this tube body.

For the purposes of the invention, "product-neutral matrix" is to be understood as meaning a matrix of a binder or material that is soft with the product filled into the tube packaging reacts and / or does not affect the properties of the product, in particular its quality and / or durability.

The term "essentially" in the sense of the invention means deviations from respectively exact values by +/- 10%, preferably by +/- 5% and / or deviations in the form of changes which are insignificant for the function,

Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures. All described and / or illustrated features are alone or in any

Combination in principle subject of the invention, regardless of their summary in the claims or their dependency. Also, the content of the claims is made an integral part of the description. The invention is described below with reference to the figure, in a simplified representation of a

Partial section through a tube packaging or tube 1 of plastic shows, explained in more detail. The tube 1 is u.a. from the tube body 2 and from the tube shoulder 3, which closes the tubular or tube-like tube body 2 at one end and in the usual way with the local tube opening 4 forming tube nipple 5 is formed. Schematically illustrated is the tube opening 4 occlusive and, for example, cap-like design

Tube closure 1 .1.

The wall of the tube body 2 is executed in several layers, in the illustrated embodiment with a least one layer barrier layer 6 and with an outer surface of the tube body 2 forming layer 7 made of plastic, which is also designed as a decorative layer or on the outside of the tube body 2 with a Decorative layer 7.1 forming

Plastic film, preferably made of a transparent and back-printed plastic film is provided. The barrier layer 6 is basically made of a material which acts as a barrier, at least to oxygen and water vapor, for example of a metallic material or a metal compound or metal oxide or metal alloy, eg, of aluminum and / or alumina {AIO2), and or of an electrically non-conductive material, for example of silicon oxide (SiO ₂ ) and / or EVOH. The layers 6, 7, 7.1 are connected to each other in a planar manner, for example using adhesion promoters. The tube body 2 is made of the sheets 6, 7, 7.1 having flat material by rolling this

Flat material to a tubular structure and made by connecting the after rolling adjacent edge regions of the sheet. The tube shoulder .3 is a form part! as a plastic and is with the tube axis TA enclosing and the tube opening remote annular or flange-shaped

Tubenschuiter section 8 inserted into the open end of the tube body 2 and connected to this in a suitable manner, for example by welding, gluing, etc., in such a way that the multilayer wall of the tube body 2 not only the

Tubenschuiter section 8 overlaps on its outer side, but also partially against the outer surface of the obliquely running or frustoconical Tubenschulter- section 9 of the tube shoulder 3 is applied, in such a way that a stepless or substantially stepless transition from the outer surface of the tube shoulder. 3 to the

Outside surface of the tube body 2 results.

The tube shoulder 3 made of plastic, for example made of PE by injection molding is provided on its entire inner surface, ie in the region of the tube opening 4, in the region of the tube nipple 5 and in the region of the tube shoulder sections 8 and 9 with a barrier layer 10, which is in the illustrated embodiment also extends beyond the edge 8.1 of the tube shoulder portion 8 to the outer surface of this section and up to the outer surface of the portion 9. The at least single-layer barrier layer 10 basically consists of a material which acts as a barrier, at least to oxygen and water vapor. The at least one-layer barrier layer 10 consists, for example, once again of a metallic material or a metal compound or metal oxide or metal alloy, eg, of aluminum and / or of aluminum oxide (AIO ₂ ), and / or of an electrically non-conductive material, eg of silicon oxide (SiO ₂ ) and / or EVOH. The at least single-layer barrier layer 10 is applied with a suitable technique continuously on the inner surface of the tube shoulder 3 and on the edge 8.1 and on the outer surface of the tube shoulder section 8, for example by vapor deposition, sputtering or electrical and / or chemical deposition.

As the figure clearly shows, connect the barrier layers 6 and 10 in the region of the connection between the tube body 2 and the tube shoulder 3 close to each other, so that the inner space 1 of the tube 1 completely or without interruption, i. is limited not only on the tube body 2, but also in the region of the tube shoulder 3 by an overall barrier layer formed by the barrier layers 6 and 10, respectively.

Although the tube 1 is formed as a plastic tube and the mechanical strength and dimensional stability of the tube 1 is essentially determined by the plastic of the tube body 2, ie by a peaty layer 7 and by the plastic of the tube shoulder 3, the tube 1 is characterized by the continuous or seamlessly adjoining barrier layers 6 and 10 dense or substantially tight to oxygen from the ambient air and in particular also for receiving such products, such as hair dyes suitable for the previously required because of their aggressiveness to plastic tubes made of aluminum. In particular, it is possible to manufacture the barrier layer 6 from the same material as the barrier layer 10 and / or at least one of the barrier layers 6 and 10,

for example, to manufacture the barrier layer 10 in multiple layers of different materials, e.g. made of silicon oxide or aluminum oxide.

In a preferred embodiment, the tube 1 is provided in the original closed state at its tube nipple 5 with a tube opening 4 overlapping or closing and indicated in the figure with 13 film forming a tamper-evident or a tamper evidence and either from the material of the barrier layers 6 or 10, or is internally coated with this material, so that the barrier layer 10 in the case of the originally sealed tube 1 also in the region of the tube opening 4 or in the region of the film there, in particular if instead of the film 13 another, molded on the tube nipple, the tube opening 4 occlusive and separable

Tamperproof is provided, it is possible to apply the barrier layer 10 forming material so that the barrier layer 10 continues seamlessly on the inner surface of the tamper-evident.

Basically, there is still the possibility that the inner surfaces of the tube body 2 and the tube shoulder 3, i. on the local barrier layers 6 and 10 more

Coatings, for example of plastic, e.g. made of polyethylene or epoxy resin are applied. This in the figure with the broken lines 12.1 and 2.2

indicated coatings are then applied so that they do not interrupt the continuous connection between the barrier layers 6 and 10. Preferably, the layers 12.1 and 12.2 are oxygen-absorbing or absorbing layers and each consist of a compound which in a matrix consists of a product-neutral binder or matrix material, e.g. in a plastic matrix,

For example, in a polyethylene matrix have at least one oxygen-absorbing additive, in the form of particles of an oxygen-absorbing material, such as a metal, a metal compound and / or oxygen-reactive and thereby oxygen-absorbing material. The production of the tube body 2 is made of a multilayer Flachmateriai by rolling this material or a blank of this material into a cylindrical blank and by joining the along a Mantell inie the blank each other

adjacent edges of the sheet. The flat material already contains the barrier layer 6 and the oxygen-absorbing layer 12.2, on the inner surface of the tube shoulder 3 and the tube tip! 5 as well as the flange-like portion 8 forming molding is the oxygen-absorbing layer 12.1 or the material forming this layer in a suitable manner, for example applied by spraying. The oxygen-absorbing layer 12.1 on the inside of the tube shoulder 3, the tube nipple 5 and the section 8 in turn consists of the compound which in the matrix consists of the product-neutral binder or matrix material, e.g. have in a plastic matrix, for example in a polyethylene matrix at least one oxygen-absorbing additive, in the form of particles of an oxygen-absorbing material, for example of at least one metal, a metal compound.

Through the oxygen-absorbing layer, oxygen which has entered the tube interior is bound by chemical reaction before this oxygen reacts with the product filled in the tube 1 and this product or its quality and / or durability

can affect.

In principle, there is the possibility that the tube 1 has either only the barrier layers 6 and 10 or only the oxygen-absorbing layers 12.1 and 12.2. However, as also shown, the oxygen-absorbing layers 12.1 and 12 are preferred

12.2 in addition to the barrier layers 6 and 10, so that also such oxygen, through the barrier layers 6 and 10 or by leaks in these barrier layers

has passed, is intercepted by the oxygen-absorbing layer 12.1 and 12.2 and stored in this before he can react with the bottled in the tube 1 product. The layers 12,1 and 12.2 in this case thus support the barrier effect of the barrier layers 6 and 10 with respect to oxygen. If at least the tube body 2 is manufactured from a multilayer flat material which has the barrier layer made of the non-metallic and / or electrically non-conductive material, it is possible to integrate an RFID sensor on the tube body 2, preferably in the multilayer flat material or between its layers. Chip or a circuit with RFID Provide function and an associated antenna structure, namely for non-contact reading and / or storage and / or reading of packmitte! - and / or product-related information. The invention has been described above in an embodiment. explained. It is understood that numerous other changes and modifications are possible without departing from the invention inventive idea. All versions are at least in common that the tube shoulder 3 made of plastic as a molded part is internally provided with the barrier layer 10 and / or with the oxygen-absorbing layer 21.2.
