Abstract
A bin for collecting refuse or garbage, for example womens' sanitary towels or napkins, comprises a tall narrow container which is open at the top and closed by a removable cover which has a substantially horizontal top surface. Disposed on the front of the bin, just below the cover, is an insertion opening having a closure flap which can be selectively opened and closed. Disposed in the interior of the bin is a bag for receiving inserted refuse or garbage. The closure flap has a shield means which projects into the interior of the bin and which covers an upper edge of the bag suspended in the bin, in the region of the insertion opening, so that refuse or garbage which is put into the bin can pass into the bag and not between the bag and the adjacent wall of the bin. The bag has suspension means at the sides thereof by means of which it can be suspended from carrying handles which project from the sides of the bin. Desirably, the bag is impregnated with or contains a deodorant and/or disinfectant substance.

Description
Background of Invention
German Utility Model No. 7 930 475 discloses a refuse bin or container which is of tall narrow form and has an insertion flap. The plan outline of this known bin, which is convex all around, is inscribed in a rectangle with a predetermined ratio between the sides, and the sides are connected by portions which are of an arcuated configuration. An insertion opening is arranged on the top and is closable by means of a double flap. A germicidal disinfection fluid is disposed in the bin.
Summary of Invention
This invention relates to refuse bins, for example for womens' sanitary towels or napkins and the like.
According to the present invention there is provided a refuse bin comprising
a tall narrow container having an insertion opening in a side wall thereof,
means enabling a bag to be removably suspended in the bin,
a closure flap which is pivotally mounted at its lower end about a horizontal axis to said side wall of the bin to enable the insertion opening to be selectively opened and closed, the closure flap having a side shield portion adjoining each of two sides of the insertion opening, and the closure flap also having a shield means which projects into the interior of a bag suspended, in use, in the bin, which shield means is in the form of an extension portion and is of such a configuration that refuse inserted through the insertion opening is certain to pass into the interior of the bag suspended in the bin, and
a removable cover which is formed as a storage surface and which normally covers an opening provided at the top of the bin for removal of the bag.
A preferred form of refuse or trash bin embodying the invention and described hereinbelow can be maintained and kept clean more easily than the known bin described above. The preferred bin has the great advantage, from the point of view of maintenance of the bin, that a bag for accommodating the refuse, garbage or trash can be removed, for example by cleaning personnel, when required, that is to say when the bag is fairly full, and can easily be replaced by a fresh, empty bag. In contrast, the known bins, which are filled with disinfecting fluid and which are comparatively large, usually have to be removed by means of a lorry or truck in accordance with a predetermined rota and replaced by fresh, empty bins. The collection rota is generally fixed, but the amount of refuse or garbage thrown into the bin may vary widely from one particular period to another. There is therefore a danger of the above-mentioned known bins either becoming overfull or being changed when they are almost empty, which involves unnecessary work and expense.
A substantial advantage with regard to handling the bins and the bags can be achieved if the bin is provided with projections at two side walls which adjoin the side wall which is provided with the flap, and extension portions of the bag which extend outwardly over the upper edges of the respective side walls of the bin are engaged with the projections.
By virtue of this arrangement, it is possible in a very simple manner and without a substantial increase in cost for the bag which is suspended in the bin or the lateral extension portions thereof to be taken outwardly over the upper edges of the two side walls of the bin and downwardly to the above-mentioned projections, so that the bag or the extension portions can be engaged with the projections.
Other objects and advantages of the present invention will become apparent from a study of the following description and the accompanying diagrammatically simplified drawings which are merely illustrative of the present invention. In the drawings corresponding components are denoted by the same reference numerals throughout.

Description of Preferred Embodiments
The illustrated refuse or garbage bin comprises a bottom housing portion 1, a top housing portion 2 which is in the form of a removable cover or lid, and a closure flap 3 which is pivotally mounted to a substantially vertical front wall of the bottom portion 1. A bag 4 is disposed in the interior of the bottom portion 1 and is engaged by means of a suspension arrangement 5 on projections 6 which are formed on the sides of the bottom housing portion 1 to act as carrying handles. The suspension arrangement may be of a different configuration. For example, two extension portions in the form of strips or bands, connected by a web or limb portion, may be secured to the upper edge of the two side walls of the bag, the strips being taken over the upper edge of the bottom housing portion 1 and the web portion which interconnects the two strips being engaged on the underside of the two projections 6. Alternatively, however, as shown in FIG. 5, the two oppositely disposed side walls may be of suitable increased length and may then be taken over the upper edge of the bottom housing portion 1, and engaged into the projections 6, by means of an opening 4' at each side thereof. In FIG. 5, a broken line 7 indicates the position at which the side wall of the bag 4 is laid over the upper edge of the corresponding side wall of the bin bottom portion 1.
In some cases it is advantageous if the top portion of a bag is modified and provided on two opposite sides with strips 10 as illustrated in FIG. 6.
The closure flap 3 is pivotally mounted at its lower end to the front wall of the bottom housing portion 1 about a horizontal axis 9 (FIGS. 3 and 4). The closure flap 3 can selectively occupy a position in which it closes an insertion opening in the front wall of the bottom housing portion 1, or a position in which it opens the insertion opening to enable rubbish or garbage to be inserted into the bin. In FIG. 1, the closure flap 3 is shown in the closed position, while in FIG. 3 the flap is shown in the open position. The closure flap 3 comprises a substantially flat front plate portion 3A, two side closure plate or shield portions 3B which delimit the front plate portion 3A at the sides thereof and which are of a substantially quarter-circular configuration, and bent strip portions 3C which serve as abutment means in the open position of the flap to limit outward pivotal movement of the front plate portion 3A such that the portion 3A can be pivoted outwardly through 60.degree..
The flat front plate portion 3A, which is directed upwardly at an angle in the open position of the flap (see FIG. 3), has a narrow extension portion 3A' which extends into the interior of the bottom housing portion 1 and which is formed as or acts as a shield means. When the closure flap 3 is in the outwardly pivoted (open) position, the extension portion 3A' is intended to cover an upper edge for a of the bag 4, which is suspended in the bin in the position of use, in such a way that refuse which is put into the bin through the insertion opening is sure to pass into the interior of the bag suspended therein, and cannot therefore pass between the bag 4 and the adjoining wall of the bottom housing portion 1. The shield means 3A' also serves as a counter-weight for producing automatic closing of the closure flap.
The top housing portion 2 which acts as a cover or lid to close the bottom housing portion 1 at the top thereof has a surface which is substantially horizontal in the position of use, so that a person using the bin is able to put a handbag or purse or the like on the top surface of the bin, which can serve as a storage surface.
The bag 4 is desirably impregnated with a deodorant and/or disinfectant substance. It may possibly also be desirable for the bag to contain a fluid with deodorant and/or disinfectant properties, for example a hypochlorite solution with a germicidal action.
