Description

The invention relates to a device for providing of hygiene articles, in particular cotton pads, with a for Picking up the hygiene article bag and a Bag-associated hanging element for hanging the bag in a deployment location.

Such devices are for example from DE 298 04 440 U1 known. In this document, one is made of a polyethylene film manufactured tubular bag for cotton pads with a suspension element in the form of a removal opening for the cotton pads surrounding the drawstring. For the production such a tubular bag is usually initially a produced by the shape of the bag predetermined film cut. This foil blank is then turned by turning it over, Folding and welding one open on one side Tubular bag manufactured. To close the for removal the opening of the tubular bag serving the cotton pads is a Drawstring provided in a circumferential the tubular bag opening Channel is recorded. This is the length of the drawstring larger than the circumference of the tubular bag opening or of the channel receiving the drawstring so that part of the drawstring hang out of an opening provided in the channel and to contract the bag opening and thus to Closing the bag can be taken.

It is also known from the cited document that with end of the tubular bag provided with the drawstring closure one at least partially from a line of weakness or perforation to provide all-round pull tab. This will accommodating the habit of drawstring bag packaging for Use on the drawstrings exposed outside the channel hang up, giving access to those in the bag Cotton pads through the bag opening encircled by the drawstring is difficult. However, it has been shown that the manufacture the tubular bag known from the cited document is very time-consuming and therefore costly because of the creation an additional channel that is used to hold the drawstring a high production engineering effort brings.

EP 0 684 922 describes a solution to this problem sealed at its upper end with a film weld Bag suggested with a hanging cord below the connecting seam is pulled through the bag so that the outside of the bag below the seam penetrates and within the bag between opposite Bag wall areas runs. To remove the cotton pads at the bottom of this bag is one of one Circular perforation around the pull tab is provided. The production this bag is also made from one suitable, essentially rectangular film cut through Fold in and seal. However, this can be done by manufacturing a channel suitable for receiving the hanging cord be disregarded because these are from the outside through suitable through openings is inserted into the bag, penetrates it and then out of the bag. Here However, the problem arises that contamination by the Penetrating openings for the hanging cord into the bag can. It can continue in the area of the passage openings damage to the bag for the cord, when it is hung on the hanging cord.

For filling the known foil bags with cotton pads the prefabricated polyethylene bag is usually machined or opened by hand and over a filling tube of a punching machine pushed for the cotton pads, with a given Number of pads filled and then with the pull cord or a suitable weld. This too Procedure is time and cost consuming because it has two steps requires that performed on different machines must be, namely the manufacture of tubular bags on the one hand and the filling of the tubular bags on the other.

Given the problems in the prior art described above The technology is the object of the invention, a easy to manufacture device of the type described Provide way of avoiding the hygiene items unnecessary contamination and damage to the bag can be provided, as well as a simple procedure to specify for the manufacture of such bags.

In terms of device, this task is accomplished by a further development of the known foil bags, which in is essentially characterized in that the suspension element subsequently on a preferably outer fastening surface of the bag that is attached in the area the mounting surface is immovable with respect to the bag.

This invention is based on the knowledge that the Problems in the prior art discussed above essentially are due to the fact that the usual pull or hanging cords always used as a suspension element are attached to the foil bag so that they are theirs originally intended function, namely a bag end can still meet. This gathering is made from the known from DE 298 04 440 U1 foil bags by sliding Recording the pull cord in a corresponding channel of the Bag enables what to the explained production technology Leads to problems. The one specified in EP 0 684 922 B1 This gathering is made possible by foil bags that the hanging bags can be moved through appropriate openings below that for closing the foil bag Serving film weld is performed, which leads to the explained Soiling problems in the bag recorded cotton pads and damage to the bags.

With the present invention, it was recognized that the previously considered necessary to gather the hygiene articles absorbing pouch with regard to that of common devices the possibility provided for at the beginning, the hygiene items through a special, during storage removal opening closed by a pull tab to remove, no longer has to be guaranteed. Then can but the suspension element with respect to a mounting surface of the bag are immovably attached to the bag. Thereby eliminates the need to attach the suspension element to provide a corresponding channel on the bag or to provide appropriate passage openings in the bag and thus also those explained above with the use of such channels or passage openings Problems. Rather, the suspension element of the invention Subsequent device to the mounting surface of the bag glued, welded and / or on the mounting surface be sealed. Such a fastening process can be produced particularly easily in terms of production technology become. Furthermore, it does not prevent the ingress of dirt passage opening in the bag the bag created. Eventually it becomes immovable Attachment of the suspension element to the attachment surface created the possibility of the fastener in flat Attach to the pouch causing damage the bag avoided by a tensile load on the suspension element can be. The bag of the device according to the invention is conveniently in the form of, for example Foil bag made of polyethylene with a substantially cylindrical jacket and at least one their axial ends sealed bag wall, wherein the mounting surface preferably in the area of the closed axial end is arranged.

A method according to the invention for the production of such Devices is essentially characterized by that a web-shaped film with a shape shoulder to an im essential cylindrical jacket-shaped bag wall and the edges of the shaped edges running parallel to the cylinder axis Film connected to form a film tube, preferably be welded together, a front Sealed end of the film tube, preferably welded and the film tube through its open rear End filled with the hygiene products as well as to form the Tubular bag is separated from the ribbon-shaped film.

In this process, the bag is made and the filling with the hygiene articles in one operation. Furthermore, this method enables continuous Production process in which the manufacture of individual Foil blanks and a subsequent folding of these blanks can be dispensed with. Rather, with the invention Process a film tube of any length made from which by closing each other opposite areas of the hose and separating individual Hose sections from the ribbon-shaped film the individual Bags are made. After making the individual, already filled with the hygiene articles with this bag continuous process can then preferably in the form a hook and / or an eyelet present suspension element one preferably in the area of one by welding one another Opposite film tube walls formed cover flap of the bag arranged mounting surfaces attached become.

Although also within the scope of the invention is a fastening element in the form of a to the fastening surface it was a good idea to use a glued hanging cord proven to be particularly useful if the suspension element in Form of a hook and / or an eye is formed because of such Suspension elements are particularly good for flat fastening are suitable on the fastening surface of the bag. With regard to the particular in the area of the suspension element high mechanical stress on the device according to the invention it has proven to be particularly advantageous if the suspension element from a different material from the bag preferably sheet material compared to one to the high strength bag material such as one rigid plastic film and / or coated cardboard.

As already mentioned above in connection with the known Foil bag explained, it is particularly useful if the Bags of the device according to the invention for formation a removal opening for the tear-off tab serving the hygiene articles having. Although the pull tab also in the bottom area of the bag can be arranged, it has in view on a particularly simple removal of the in the bag ingested hygiene items proved to be particularly useful, when the pull tab forms an elongated Discharge opening starting from the wall of the bag into a Suspension of the bag extends the upper lid area of the bag. This allows the top of the in the bag to access the recorded hygiene items. Then one Evasive movement of the hygiene articles in the bag through the after hanging the bag prevents the bottom bottom of the bag making it easier to grasp the hygiene items becomes. The removal opening can be formed particularly easily, if the pull tab at least partially from a Line of weakness and / or perforation in the bag wall and / or the lid area and / or a bottom of the bag is circulating.

In the manufacture of a device according to the invention with the method according to the invention, it has proven to be special proven to be advantageous if, for example, in the form of round, oval or rectangular cotton pads present hygiene products in the form of according to a desired package size prepared batch with a predetermined number of Hygiene products in a horizontal loading direction in the film tube are filled. By preparation the hygiene product stack becomes a particularly fast filling which enables film tubes. On the other hand, through the introduction of the prepared stacks in the horizontal direction prevents the prepared stacks from falling apart.

When executing the method according to the invention facilitates the introduction of the hygiene articles into the film tube when the sheet-like film with the shape shoulder around a substantially cylindrical jacket-shaped filling tube for which hygiene products are laid. The shape shoulder points to this expediently a curved guide surface, starting from an essentially flat management area passes into a cylindrical jacket-shaped guide area, so that the web-shaped passing the guide surface of the form shoulder Foil based on your essentially flat initial state to the essentially cylindrical jacket Bag wall is formed.

To ensure a continuous production process it has proven to be advantageous if the film tube before, during and / or after the introduction of the hygiene products in the loading direction is promoted because this creates the possibility already during or immediately after filling the film tube, if necessary before separating the filled film tube from the web-shaped Foil used to make the following tubular bag required film tube section from the web-shaped To produce foil.

To ensure contamination-free storage the hygiene article in the tubular bag can do that the loading direction at the rear end of the film tube Introduction of the hygiene products closed, preferably welded become. This can separate the film tube from the sheet-like film at the same time as it is closed of the rear end of the film tube. Furthermore, closing the back end of the film tube too still simultaneously with the closing of the front end of a subsequent film tube to make a special ensure a fast production process.
