Laundry transport bag D 5554

The invention relates to a laundry transport bag, in particular for self-emptying in a drum washing machine, consisting of a web of fabric. Such sacks are used to transport laundry, for example for hospitals, hotels and rental laundries. The laundry bag often makes a constant cycle from the place of use to the washing facility and after filling fresh laundry from the washing facility back to the place of use. The sack should optionally be filled with used laundry and at will can be washed with or without used laundry.

Such a laundry transport bag, especially for clinic and Infectious washing is known from DT-GM 1,939,621. This sack however, on the one hand, it has the disadvantage that it can be put in the washing machine only very gradually emptied by itself. On the other hand, its manufacture from a rectangular section requires a considerable needlework. Another known from DT-AS 1 585 726 Laundry transport bag consists of two nested Sack parts that are connected to one another at their lower ends and each sack part with a longitudinal slot is provided, the one longitudinal slot on the longitudinal edge of the other bag part and the other longitudinal slot on the one on the the other side lying longitudinal edge of the second sack part runs. This sack empties relatively quickly in the Washing machine, but this has the disadvantage that the laundry can easily fall out of the slot during transport,

In addition, this laundry bag also requires considerable sewing work in its manufacture.

Finally, a self-emptying laundry transport bag is included a drum washing machine, which has at least one substantially rectangular web of fabric, known from DT-GM 7 533 793. Here, approximately in the middle of the side edge of the rectangular fabric web, another, much narrower fabric web is attached with about the same side length as that of the first web of fabric. When the bag is formed, the two are opposite one another Side edges of the first web of fabric laid overlapping one another to form a tubular structure, and the essential narrower web of fabric is spread over the slit thus formed. The main disadvantages of this laundry bag exist in that the cut to form the sack either - in the one-piece design - in the corners of the abutting web parts can easily tear or requires considerable reinforcements or - in the case of a two-part, sewn-together design, additional Sewing is required without the disadvantages of the one-piece design being eliminated. Furthermore, since the upper The end of the sack has partially double and even triple layers of material lying loosely on top of each other, is the gathering of it difficult to form sack closure, and there is a constant risk of slipping or falling apart of the individual Layers of fabric.

The invention is based on the object of a laundry transport sack to create, which can be produced in an even simpler manner, without particularly vulnerable areas with respect to tearing available. When full, the new sack should be stackable, store its contents safely and be self-sufficient Nevertheless, empty or have emptied quickly and easily in the drum washing machine.

In the case of a laundry transport sack consisting of a fabric web the solution according to the invention is that a single square fabric web is provided to form the sack between the ends of their opposite straight narrow sides

the long sides extend like a flat hyperbola drawn inwards like a waist, that when the sack is full the long sides are placed overlapping each other to form a tubular structure around the sack filling and that the narrow sides for closing provided by gathering and tying.

The invention creates a laundry transport sack which, in terms of both its cut and its handling is extremely beneficial. The cut consists of a single, one-piece piece of fabric that is merely attached to the long sides - symmetrical to the one that intersects the narrow sides Longitudinal axis of the sack - hyperbeiform or also circular segment-shaped Has cutouts. The cut - measured perpendicular to the longitudinal axis of the sack - should be about 15 in the middle to 25 #, preferably on the order of about $ 20, narrower than be on the narrow sides. Because of the peculiar shape of the cut, the new laundry transport sack is also known as the "trumpet sack" designated. This also offers in terms of its handling when clamping in the laundry bin or when closing no problem. Since the new laundry bag has no double-edged layers of fabric, the closure is simple and the closure safe, so that the web of fabric gathered in the fastener does not slip away and the tied sack does not fall apart is to be feared. The very good transport properties should also be emphasized of the laundry transport bag according to the invention. Due to the special shape, the filled sack receives from A uniform diameter from top to bottom, so it can be stored excellently, as was the case with earlier potbellied or round laundry bags difficult

According to a further invention are to be closed by gathering provided narrow sides at a distance from the edge that is just sufficient to be closed with Velcro fasteners scheduled. Preferably ge to close the laundry bag a Velcro fastener sewn on at a distance of about 10 cm to each open side of the bag. The durability of such Velcro fasteners is excellent. Even with greater impact loads, for example when the sack hits from a great height, it remains

the sack closed. With one-sided closure the new sack this can be used as a laundry collector. Optimal emptying of the sack is guaranteed by opening on both sides; this is particularly important for hospital linen to be disinfected, for example.

Further details are explained on the basis of the schematic drawing of an exemplary embodiment of the section of the new sack.

An expanded section is shown in the drawing. This consists of a single square, elongated one Fabric panel. The narrow sides 2 of the cut, which are perpendicular to the longitudinal axis 2, are gathered when the sack is closed and tied together with the help of the Velcro fastener 3. While the narrow sides are straight, each long side is 4 · des Cut than from a corner 5 of the cut towards the Longitudinal axis 1 bent inwards and bent back to the next corner 5 line formed. The long sides 4- are preferred both mirror-symmetrical to the longitudinal axis 1 and mirror-symmetrical to the transverse axis 6 perpendicular to the longitudinal axis 1 shaped. Color stripes 7i especially with a company name.

In one embodiment, the laundry transport sack according to the invention is 120 cm long, on the two outer edges or narrow sides 72 cm and in the middle 62 cm wide, the filling weight is between 10 and 12 kg of dry laundry. The emptying times in the washing machine are two to two and a half Minutes. The Velcro fasteners are sewn on at a distance of 10 cm to each open side of the bag.
