BAG AND RETAINER THEREFOR

Abstract: In order to permit easy and hygienical disposal of e.g. sanitary towels in a cloakroom, a bag retainer can be fitted on the wall, and a bag (4) can be hung on the retainer. The retainer comprises a traversing resilient carrier rail (3) on which a bag is hung (4) which is provided with a flap (5) at its mouth and which is down­ wardly open and designed to fit the reception of the carrier rail (3). The flap (5) and the carrier rail (3) have sloping side edges (7, 8) and are dimensioned so as to allow the bag to slide further down over the carrier rail (3) once the bag is stretched lengthwise with a view to keeping the rim stretched and the bag closed. When the mouth of the bag is to be opened, one pulls out the uttermost part of the mouth, and when the bag is to be closed, one lets go of the mouth part whereby the resilient carrier rail will close the mouth of the bag.

Description: The invention is related to a bag and a retainer for fitting of the bag on a wall or the like, which bag is provided with a folded down collar so as to create a downwardly open pocket along at least one side of the top edge of the bag, and which retainer comprises means allowing the opposite top edges of the bag to be moved between a closed position in which the top edges are in close abutment and an open position in which they are spaced from each other. Ladies' cloakrooms for instance are equipped with such bags and retainers, where the possibility of depositing sanitary towels and the like in a closed bag is appropriate, as it is thus avoided that used sanitary articles are thrown into the toilet where they may cause interruptions of outflow or even chokings. From Danish document No. DK-A-113,625 laid open to public inspection is known a frame comprising two carrier strips which are hinged together and are kept compressed by a spring. A bag can be arranged having a mouth channel on each strip so as to manually open the mouth by pressing one strip with a view to disposal of a towel into the bag, whereupon one lets go of the strip and the mouth will close. However, this carrier frame is difficult to use. It takes some routine to place the bag as there are two channels along the mouth for insertion on each carrier strip while these are in close abutment. Further, the handling of the opening procedure is inconvenient as it it necessary to permanently press against the wall while the towel is taken through the mouth of the bag. The distance between the free part of the strip to be pressed and the mouth of the bag is rather big, and the shape of the mouth is a V-shape. If the frame is mounted in a narrow room, such as a bathroom, such a procedure is difficult and could often cause smudging of the mouth of the bag which is again unhygienic and may give rise to unpleasant odours. From DE-OS No. 2,304,670 and US patent No. 3,912,208 are known bag retainers comprising two resilient strips on to which the mouth of the bag is attachable. By pulling one strip the mouth of the bag will open, and when the pulling ceases, the bag will close again. However, these known retainers are also difficult to handle since it is imperative that the bag is inserted accurately on both strips. Add to this the relatively complex design of the retainer having hinges at the ends of the resilient carrier members, which makes the retainer more expensive and which makes it more difficult to keep the retainer and the suspension clean. From FR-A-2 344 471 is known a bag holder which consists of three parts: a support, an endless elastic band and a handle. The support is an oblong plate having a levelled rear side designed to be fitted onto a wall with its largest length being substantially horizontal. The opposite front side has a longitudinal section which curves in such a manner that the plate is thickest at its centre. In each of the two opposing short end edges two notches are provided so that the centre of each end edge appears as a tongue. The plate is provided with holes for receiving means of attachment such as nails or screws by which the plate can be attached to the wall. The elastic band can be arranged with diametrically opposite parts around the two tongues so that the band between these extends as two parallel band lengths along the curved front side of the plate. The bag is an ordinary bag where one edge at the mouth of the bag is inserted from beneath and squeezed between the plate and the upper of the two parallel band lengths, whereafter the other edge is inserted from beneath between the plate and the lower parallel band length and turned out and down around it. The handle is made of a wire and is designed substantially in the shape of a U where each of the free limbs is curved for the formation of a hook. These two hooks are inserted in the mouth of the bag so as to catch around the folded edge of the bag and the lower parallel elastic band length arranged therein. When waste is to be deposited in the bag, the handle is pulled out whereby the bag is opened so that waste can be put into the bag, whereafter the handle is let go of so that the lower elastic band length will pull the folded edge of the bag inwards towards the curved front side of the plate in order to close the bag again. The applied bag is of a generally known kind and has not previously been provided with pockets along its mouth. When the bag is opened by pulling at the handle, the bag is held partly by means of the force exerted by the upper elastic band length on the curved front side of the plate and partly by the other side edge of the bag which is turned out over the other elastic band length. This fold will, however, tend to straighten itself; the elastic band lengths would seem to provide a poorer fixture of the open bag than of the closed bag. This is most unfortunate since a reliable fixture is required particularly when the bag is open, because the inertia of the waste deposited in the bag will produce a downward force towards the bottom of the bag. The known bag holder is not able to hold a bag when its weight exceeds a certain height, because the known bag holder can only hold the bag by the friction occurring due to the force being exerted by the two elastic band lengths on the side walls of the bag and on the curved front side of the plate when the bag is closed. It should be added that the elastic band lengths tend to collect dirt from waste being deposited in the bag which is a disadvantage. It is the object of the invention to overcome this large number of drawbacks in known frames, which object is achieved in that the retainer comprises a bracket which is to be mounted on a wall and which carries a single traversing carrier strip of a resilient material, and in that the pocket is a seamed pocket along the mouth of the bag, which pocket may be arranged over and be held by the single carrier strip. Contrary to the bag holder known from FR-A-2 344 471 which consists of three parts, the retainer according to the invention only consists of one part. This one part is substantially of the shape of a T where the stem or the vertical line in the T forms the bracket which is provided with holes which can receive attachment means by which the bag holder can be fitted on a wall. The horizontal line of the T makes up a single carrier strip which is received in a pocket already provided on at least one side along the mouth of the bag. The opposing free end edges of the single carrier strip converge upwards in the position for use of the bag holder so that a bag is squeezed over the bag holder; this attachment is gradually reinforced as the weight of the bag increases. As a consequence of this, the bag and retainer according to the invention are considerably easier to produce than is the known bag holder with bag, the retainer is able to hold the bag during its gradual filling in a far more reliable manner, and the retainer and bag are far more hygienic and thus require less maintenance and cleaning. Thus, it is possible by means of only a single carrier strip to both hang the bag and open it by pulling the outer rim of the bag. This procedure ascertains maximum opening, and consequently sanitary towels and similar elongate or rolled up objects will easily pass through the opening into the bag without touching or smudging the rim at all. Further, this design offers a much better contact with the opening of the bag as one actually has a firm grip of the bag and at the same time both sees and feels the opening. Hanging and removal of the bag is extremely simple because only the innermost part of the bag will have to be fitted on the single carrier strip which is easy when the strip is spaced from the wall at a convenient distance whereby it only remains to pull the bag on to the retainer. Removal is likewise easy and hygienic as the bag is suspended in one pocket only. As mentioned in claim 2, the inclined shaping of both the strip and the opposite side edges of the suspension pocket makes it easy to fasten the bag because this is self-centering, and further the tensile stress on the upper rim of the bag will be lower, thus facilitating access for the fingers to grip the rim during opening of the bag. As mentioned in claim 3, the idea of making the pocket higher than the single carrier strip makes it possible for the bag - when it is filled and consequently weighted - to slide lower on the single carrier strip without weakening the closure although the foil has stretched. Finally, it is expedient, as mentioned in claim 4, that the strip is outwardly bent at its centre relative to the wall since this makes handling easier. The invention is further described with reference to the drawing in which Fig. 1 is a rear view of the retainer with a bag, fig. 2 shows a section through the retainer and the bag, seen in the direction of II-II in fig. 3, fig. 3 is a top view of a mounted retainer and bag, fig. 4 shows the retainer and the bag in an open position, and fig. 5 is a front view of the bag. An example of an embodiment of the bag and retainer is shown in fig. 1. The retainer comprises a bracket 1 having at its lower part a mounting 6 with holes for fixing screws, as shown in fig. 2. Further, at its upper part the bracket 1 is bent outwards so as to be outwardly displaced at its top relative to the mounting 6. Moreover, an actual resilient and arcuate single carrier strip 3 is fixed in a horizontal position at the top of the bracket. At the ends of the single carrier strip 3 the edges 7 diverge towards the bottom of the carrier strip 3 having smooth roundings and designed in such a manner that the strip tapers towards its top side. The retainer may be manufactured of various suitable materials, and of metals rustproof steel is preferable, partly because of its keeping qualities in moist surroundings, and partly because of its fine and stable resilient qualities. The ends of the single carrier strip 3 can be provided with bosses as shown or in a similar manner in order to prevent the bag from being cut or torn by the rail. The bag may be shaped as shown in fig. 5. It is mainly manufactured out of plastic foil of a suitably strong quality. Principally, it is produced by welding the side seam of a folded foil lane, and further an outwardly folding of the uttermost piece of foil is provided on the upper part so as to procure a downwardly open pocket 5 on the outside of the bag 4. This pocket 5 will preferably be available on both sides of the bag meaning that any of the two sides of the bag can be placed on the retainer; furthermore, this makes the use of the bag easier as the rim is easilier gripped. Further, the side seam 8 at the sides of the pocket 5 converges upwards rendering the opening of the pocket larger at the bottom than at the top. At the bottom this corresponds to the length and shape of the single carrier strip 3 allowing hanging of the bag at its lower part, as demonstrated in figures 1 and 2. When hanging, the bag and retainer will appear as shown in fig. 3, in which the retainer is fitted on a wall 2. When opening the bag 4 one either inserts one finger into the outer pocket thus totally avoiding contact with the rim part, or one inserts one finger between the rims of the bag at the top. Thereupon, the free rim of the bag is pulled outwards in the direction of the arrow, as shown in fig. 4. This position permits disposal of a sanitary towel or the like in the bag which will subsequently return to the closed position shown in fig. 3 by means of the spring tension of the single carrier strip 3. As the bag is gradually filled or being stretched at its upper part, the pocket 5 will slide down on the single carrier strip 3 and as a consequence of which the pocket and the strip will remain in constant abutment. Thus, the required degree of tension in the rim area of the bag is maintained as is the constant tight closure of the bag whereby unpleasant odour is avoided completely. When the bag is to be replaced, it is lifted off the single carrier strip, i.e. by inserting fingers underneath the pocket, and the bag with its contents is lifted off the single carrier strip. In that way direct contact with the rim area and the contents is completely avoided, which makes the use of the bag hygienic.
