Definitions

• the present invention relates generally to a dust container for a vacuum cleaner, more specifically for the type of vacuum cleaner which employs a bag with a suction opening, the bag being made of a material which, essentially, is permeable only to air, and a mounting plate, which can be attached to the bag, provided with a suction opening aligned with the suction opening of the bag, and which mounting plate is designed specifically for the model of vacuum cleaner in which the dust container is to be used, for the purpose of fitting the dust container in that model.
• dust containers for vacuum cleaners are usually of the disposable type, in addition to which each model of vacuum cleaner normally requires a specially designed dust container .
• a first purpose of the invention is, in the absence of such standardisation, to provide a dust container which is essentially suitable for use in practically all current vacuum cleaner models.
• a second purpose of the invention is to provide a dust container which is also reusable, that is to say, which is not of the disposable type.
• a vacuum cleaner dust container of the type described initially which dust container is characterised in that a front plate enclosing the suction opening of the bag, and being of a shape independent of the model of vacuum cleaner in which the container is to be used, is provided as reinforcement around the suction opening; that the bag material around its (the bag's) suction opening is fixed to the front plate; that means are provided of attaching the mounting plate to the front plate; and that the bag is made of a synthetic material and can be sealed at an end separate from the front plate by folding an open end section adjacent to the said end, and by securing the said end section in the folded position by openable fastening of the opposed, folded surfaces.
• a specifically designed front plate from a commercially available dust container of the disposable type may be used as a purpose-made mounting plate.
• the front plate may suitably be made in two sections, between which the bag material around the suction opening is fixed, for example, by means of a snap-in arrangement.
• the opposed surfaces of the bag created by double folding of the end section may be provided with fastening strips, which may suitably be fastenable to each other and may preferably consist of Velcro tape.
• the means of attaching the mounting plate to the front plate may be of a permanent nature.
• a proposed embodiment of such permanent means of attachment may take the form of double-sided adhesive tape attached to the outer side of the front plate.
• the bag may preferably be made of some type of synthetic material capable of withstanding repeated use.
• the bag may be provided with two oppositely located gripping tabs, between which the front plate is located, to facilitate removal of a dust container from a vacuum cleaner and its fitting in a vacuum cleaner.
• Fig. 1 is a perspective view of an embodiment of a dust container in accordance with the invention.
• Fig. 2 is a partial cutaway view of part of the dust container illustrated in Fig. 1.
• Fig. 3 illustrates the use of a dust container as illustrated in Fig. 1.
• a dust container for a vacuum cleaner in accordance with the invention consists of a bag 1 of a material which, essentially, is permeable only to air.
• the bag may be made of a fabric which, firstly, complies with the requirement of air permeability and, secondly, is sufficiently durable to permit repeated use.
• the bag 1 is provided with an opening 2 at an end 3.
• Double folding of an end section 4, as illustrated in Fig. 3, and securing of the said end section in the folded position, for example, by means of Velcro fastening strips 5, 6, enables the bag to be sealed in a secure manner, while also enabling it to be opened by releasing and unfolding the end section 4 into the position indicated by the broken lines in Fig. 3.
• the bag 1 has a suction opening 7, which is enclosed by a front plate 8.
• the suction opening 7 may, further, be provided with openable sealing flaps 9, which may either be separate or may form part of the material of the bag 1 or the material of the front plate 8.
• the sealing flaps 9 are openable when the dust container is fitted in a vacuum cleaner, to permit the dust to pass through the opening 7.
• the flaps may, furthermore, preferably be spring-loaded to prevent the escape of dust from the opening 7 when removing and emptying the dust container.
• the front plate 8 provides reinforcement around the suction opening 7 and may, as illustrated in Fig. 2, consist essentially of two identical sections,
• the front plate 8 is of a shape which is independent of the vacuum cleaner in which the dust container is to be used.
• the plate may suitably be of smaller dimensions than the front plates in most vacuum cleaner models.
• the suction opening 7 is sufficiently large to suit the suction opening of the front plates in most vacuum cleaner models.
• a double-sided adhesive tape 10, with a protective covering 1 1 is provided on the outer side of the front plate 8.
• the double-sided adhesive tape 10 comprises the means used to attach a mounting plate 12, shown in Fig. 3, designed specifically for the vacuum cleaner in which the dust container is to be used, to the front plate 8.
• the mounting plate 12 is usually of a special shape for each vacuum cleaner model.
• the dust container in accordance with the invention is generally usable and can be adapted simply for each individual model of vacuum cleaner by attachment of a mounting plate 12, designed specifically for the vacuum cleaner in question, to the front plate 8 of the dust container.
• the mounting plate 12 may conveniently be obtained from the specifically designed disposable-type dust container normally used in the vacuum cleaner in question.
• the bag 1 is provided with two oppositely located gripping tabs 13, between which the front plate 8 is located, to facilitate fitting of the dust container in accordance with the invention in a vacuum cleaner and its removal from the cleaner.
• a dust container in accordance with the invention as described above is advantageous, firstly, in that it can be used with any vacuum cleaner model whatever and, secondly, that it can be used repeatedly. This obviously means that the cost to the consumer is greatly reduced, in addition to which the number of variants which must be stocked by dealers can also be reduced substantially.
