Description

Self-adhesive container

The invention relates to a self-adhesive equipped container with an opening hole for attachment to an artificially created body opening, wherein the self-adhesive part in the form intended for all-round bonding on the body a self-adhesive label is firmly connected to the container. So concerns the invention in particular a container for supplying an ostomy.

Containers for supplying an ostomy are known.

In addition to standard bags with a fully self-adhesive label, the is glued or welded to the bag, there are already more complex developments, which try to avoid the disadvantages of the standard bag.

Such disadvantages are difficulties with the full-surface film label It can be easily adapted to the stoma exit, as it has no sealing properties. The result is peeling, which leads to extremely unpleasant skin irritations and damage caused by the faeces etc.

leads.

In order to avoid these disadvantages, DE-OS 2,808,717 proposed that the device for attaching an ostomy pouch should be designed in such a way that that there is a sealing ring (7) made of karaya rubber directly around the stoma opening, while further outside around this sealing ring around an adhesive layer (8) * for ensures the necessary adhesion, the whole being arranged on a disc (3) made of plastic is. This part surrounding the opening is relatively stiff, while the edge areas are more flexible. However, this arrangement has not been able to fully satisfy either Although a seal takes place, the adhesion is so low that a additional security with a belt is advisable. This will make this arrangement does not meet the requirements for comfort and safety, especially since an intimate application of the sealing material is made difficult or even prevented will.

The object of the invention was to avoid these disadvantages and a To develop a container in which a carrying belt is completely dispensed with can.

This problem is solved by a container that is characterized by it is that concentric around the circular bag entry opening on the self-adhesive Label surface a sealing ring deviating from this in the composition is applied with its own self-adhesive properties.

A preferred embodiment is characterized in that the self-adhesive label surface made of a polyacrylate or rubber self-adhesive mass consists, with the sealing ring applied to it in the center in the form of a circular ring and consists of a water-absorbent, swellable, thermoplastic, self-adhesive Dimensions consists, which on the side facing the self-adhesive of the label a Has carrier film.

This combination of the adhesive label and the sealing washer on The advantage of being based on a thermoplastic compound is that the container can also be used under Exposure to moisture, urine and faeces adheres firmly and securely that the shape of the adhesive element remains unchanged while maintaining its shape # and that there are no residues on the skin that are difficult to remove. Another The advantage is that the transition from the sealing ring to the self-adhesive label surface on the skin, so to speak, a brake for the passage of liquids or gases represents. Because should ever move between the sealing ring and the skin of the abdomen etc. form channels, folds or the like, through which gas can emerge, for example could, such a channel ends with the end of the sealing ring. There starts relatively soon the next, strong gluing through the label surface, the one Passage prevented. For practical use, this lies on top of one another coordinated function of the two adhesive elements is a decisive step forward.

The good adhesion properties together with the dimensional stability as well in the event of moisture and the flexibility of the sealing ring after application the body also lead to a particularly good permanent seal on irregular skin areas such as scars or inflammation in the stoma area is achieved.

The combination of the sealing ring, which is ideal for the ostomy area is, with an adhesive label, which the skin movements in the more remote skin area Can participate extensively and completely, is therefore a label with more uniform Clearly superior to adhesive surface or full-surface sealing washer. In the area of the This is because stomas are particularly important in terms of sealing, adhesion and non-interference high demands are made by faeces and moisture absorption, while in the surrounding Neighboring area the emphasis except on liability more on maximum flexibility, adaptation to the irregularly structured skin and especially to high shear strength Value is placed.

In particular, there is a permanent sealing function immediately around the stand desirable, while at the same time good adhesion and swellability the moisture given off by the body through sweating are indispensable.

This seal effectively prevents the strongly skin-irritating Faeces lead to unpleasant skin irritation in the ostomy area, and the good adhesion and dimensional stability of the sealing ring on the skin ensure that this sealing function remains fully intact even after the bag has been worn for a long time. This sum of the Properties becomes particularly good with a compound based on rubber and resins fulfilled, which also contains swellable substances. About swellability the sealing ring must have a certain thickness, so that the flexibility is negligible is restricted. The inventive combination of sealing ring with adhesive label represents a successful solution by reducing the flexibility in the interior The adhesive seal is complemented by high adhesive strength and flexibility in the area of the adhesive label.

This adhesive label, in the center of which is the sealing ring is primarily responsible for the large-area, secure adhesion to the skin because it is designed so that it has a good permanent bond strength on the skin (adhesion) and thus the downward direction through the bag Can absorb shear force without peeling off. Because the tensile load on the upper part of the bag is particularly strong, you need a special one in this area permanent and good bonding, which is not in the desired extent from a mass can be provided, which should also assume a sealing function; much more are particularly good for this, the very shear-stable and firmly adhering rubber or polyacrylate compositions of known type are suitable.

Accordingly, the dimensional ratios are: in the case of a square Total foil-based label (but with rounded corners) of 11-13 cm Edge length and an ostomy hole of 25-30 mm in diameter, which is equal to the inner diameter of the sealing ring, the outer diameter of the sealing ring should be, for example 65-90 mm. Disregarding the cancellation hole, the area ratios are from sealing ring to free, adhesive label surface so preferably about 2: 3 to 2: 5, but can also be smaller or smaller, depending on the intended dimensions to be taller. It is particularly important that the label adhesive surface is always around Sealing ring protrudes significantly.

The label itself on which the sealing ring is attached is by welding or gluing in a known manner to the bag part tied together. The bag consists in particular of odor-proof, flexible film.

For qualitative reasons, the connection is expedient via a Welding process produced, preferably according to a welding shape.

DBGM 77 09 687 is chosen. As is known per se, the welding also be arranged in a suitable manner so that a weld flang in) the area of the Stueloches is attached. But it can also be a weld in another more suitable Form will be pretend; furthermore, it can - then be self-adhesive on both sides - Eitkett also fully or partially (e.g. only around the edge) in an appropriate way Way to be glued on the bag.

All common self-adhesive systems are used as the adhesive mass of the label in question, e.g. those based on natural and / or synthetic rubber as well those from the field of polyacrylates. Adhesives are particularly suitable according to DE-OS 2 557 566, since on the one hand they are anti-inflammatory due to the addition of Karaya act, on the other hand also result in good adhesive strength and, in particular, shear strength.

The sealing ring (initially in the form of a round disc) preferably consists of a highly adhesive compound based on synthetic rubber, the one that absorbs liquid and swells slightly for better swellability Contains substances. The following should be mentioned here: carboxymethyl cellulose, pectin, gum arabic, Tragacanth, gelatine, alginate and especially karaya, the karaya portion being preferred 1 - 60%, especially 20 - 40%. This mass lies in particular in a thickness from about 0.2 to 3.0 mm, with the range from 0.5 to 2.0 mm being preferred. On the one hand, this mass is e.g. inseparably glued to a suitable film, wherein a one-sided electrostatically pretreated polyethylene film in a Thickness of 40 - 100 pm has particularly proven itself, as it guarantees a secure bond, otherscits but riocti reasonably [Icxible is to not exhibit the stiffness of combined layers. It can basically be on this film can be dispensed with, but the pure sealing compound is not dimensionally stable, which is compensated for by a laminated film. The just mentioned side of the Sealing ring compound is applied as a round disc to the one that will later be aligned with the body Foil side of the then finished bag already @@@ bound, yellow adhesive tape eb <nde ii kett cjebrdeht - with or without stabilizing film so that this is in his original adhesive surface is reduced by the area portion of this pane. The other side of the sealing ring is covered with a release paper to protect it. This release paper preferably also has a disk shape that extends all around the sealing ring protrudes, e.g. about 3 mm. Either the protruding Part can be used as a handle to make the release paper easier to demolish, or it can after lifting one corner of the cover of the label adhesive surface with a single Handle the cover of the label adhesive area together with the release paper of the sealing ring are removed so that then immediately the entire adhesive surface to Application is exposed, i.e.

Label adhesive surface and O-ring adhesive surface.

To protect the surrounding label adhesive surface, this can also be covered with a release paper.

Then a correspondingly large one must be used before the sealing washer is introduced Circular area can be punched out of the paper and removed so that on the then exposed adhesive surface the sealing washer can be glued.

Or the entire release paper is used before the sealing washer is applied removed from the adhesive label, then the sealing washer is attached centrally to the label, and then an adhesive-repellent film over the entire label surface including Sealing washer placed.

Then the composite - consisting of bag film, is attached to it Adhesive label on which the sealing washer with its release paper is located in the center and, if necessary, a protective film covering everything - the ostomy hole punched in the required diameter.

Further advantageous embodiments are given in the claims.

The invention is illustrated below using examples and drawings will.

Example 1 a) Production of the sealing washer (4).

In a heatable kneader, 45 parts by weight are low molecular weight Polyisobutylene (Oppanol (R) B 15 from BASF) with 34 parts by weight of sodium carboxylmethyl cellulose at approx.

kneaded until (after about 4-6 hours) a homogeneous mixing has taken place; then 8 parts by weight of a hydrocarbon resin softening at approx. 1000C, 9 parts by weight of a polyterpene resin which softens at about 115 ° C. and 4 parts by weight Karaya powder added and everything together at about 1200C in a turn kneaded homogeneous mass. Then the still hot mass (2) under pressure on a siliconized release paper (1) to a thickness of approx. 1.0 mm rolled out and after cooling immediately with a 60 µm thick, electrostatic pretreated PE film (3) covered in such a way that the pretreated film side comes into contact with the free earth side. This sheet-like material (Fig. 1) is either cut into sheets approx. 100 cm in length or rolled up into a lollipop. The sealing washers (4) are then made of circular shapes from this sheet or roll product Punch out the shape with the required diameter by - from the PE film side (3) starting - the multilayer material (Fig. 1) is completely severed. In the present For example, the diameters are 65, 70, 75, 80, 85 or 90 mm.

b) Manufacture of the combination of self-adhesive label and sealing ring.

jin in ilUlicwEler Wcisie coated, for label production provided self-adhesive sheet material with, for example, a film as a carrier material - Consists of siliconized release paper, self-adhesive and a film that can be welded to the bag film in label sheets (5) of 110 x 110 mm with rounded corners <corner radius 36 mm) punched. in the At the same time, the center of the individual label becomes the release paper in a circle up to the adhesive punched through with a diameter that is 2 mm larger than that of the to be applied sealing washer (4) with one of the diameters mentioned under a), e.g. 70 mm.

The label designed in this way is used in the usual operation for the production of self-adhesive collection bags by using a line weld (9) in the form according to DGBM 7 709 687 with that film side (10) of the later Bag is intimately connected, which will be directed towards the body (Fig. 3).

Then the circular punched release paper of the label (5) peeled off, so that the label adhesive surface is freely visible in this form (11) (Fig. 2). The film side (3) of the sealing washer is now placed on this adhesive surface (4) glued (Fig. 4). This sequence of layers is then placed in the center of the sealing washer Punched through a circle with a diameter of 30 mm, with which the ostomy hole (14) is made is. In addition, the sealing washer (4) thus becomes a sealing ring (15). The diameter of the stoma hole (14) is therefore 40 mm smaller than the outer diameter of the Sealing washer (4). The punched-through layer sequence according to FIG. 5 is now more usual Way welded together with a second sheet of film to form a finished ostomy pouch.

Before using an ostomy pouch of the type described above, you must one after the other the protective (separating) papers from the adhesive label (13) and from the sealing ring (15) must be peeled off so that both adhesive surfaces are free for bonding in the ostomy area are, or it will be at over standing cover, the sealing ring Both covers (e.g. protective papers) can be removed with a single movement, such as this is described above.
