Definitions

• This invention relates to storage bins.
• a stored item be separated from its environment.
• an item producing a foul odor such as a used diaper
• a barrier impervious to the odor so as to prevent the odor from being released into the environment.
• a food such as a sandwich or fruit
• a food to be stored should be separated from its environment in order preserve the freshness of the item or to prevent contamination or drying out by the environment.
• the present invention provides a bin for storing items.
• a self-adhering film such as a saran (i.e. a plastic having vinylidine chloride as its principal monomer).
• the bin comprises a base container for storing the wrapped items below a wrapping assembly.
• the wrapping assembly includes two trays configured to receive a roll of self-adhering film.
• the wrapping assembly also includes a first and second cylindrical rollers. Rotation of the rollers are coupled to each other so that rotation of the first roller, for example by means of a knob, in one direction causes simultaneous rotation of the second roller in the opposite directions In use, a small amount of the film is extended by hand from each roll and the ends are pressed together.
• the ends of the two rolls of film are thus bonded together.
• the bonded edge is then manually fed in between the rollers as the rollers are made to rotate. This causes the two sheets of film to pass between the rollers into the base container. As the two sheets of film pass between the rollers they are crimped together by the end sections of the rollers so as to bind the two sheets together along the edges.
• An object to be stored in the bin such as a soiled diaper or food item, is now placed between the two rolls of a film over the rollers.
• the rollers are then rotated so as to draw the bonded edge of film further into the container.
• the object passes between the rollers.
• the object passes between the rollers crimping of the film at the end sections of the rollers seals the two rolls of film around the object.
• the two rolls of film may be cut.
• the rolls of film are preferably perforated at intermittent intervals to facilitate manual cutting of the film by a user.
• the cut ends of the two sheets of film wrapping the object are then manually pressed together so as to bond the ends together. Further rotation of the rollers causes the object, now completely wrapped in the film, to be released from the rollers and to fall into the container.
• the invention thus provides a bin for storing objects comprising: (a) a container;
• each tray configured to receive a roll of self- adhesive film.

• Figs. 1 to 4 show a first embodiment of a bin in accordance with the invention.
• the bin is shown in exploded view in Fig. 1.
• the bin comprises a base container 1 supporting a wrapping assembly 2.
• the wrapping assembly 2 includes two trays 4 and 5 (Fig. 2).
• Each of the trays 4 and 5 are configured to receive a roll of self-adhering film 3.
• the self-adhering film 3 may be formed, for example, from a saran (i.e. a plastic having vinylidine chloride as its principal monomer).
• covers 10 are opened to expose the trays 4 and 5 (Fig. 2). After a roll of film 3 has been placed in each of the trays 4 and 5 (Fig. 1), the covers 10 are closed over the rolls of film 3 (Figs. 3 and 4).
• Adjacent to the rolls of film 3 is a pair of cylindrical rollers 6 and 7.
• the rollers 6 and 7 are constructed in three sections.
• the rollers 6 and 7 have a central section 12 formed from a resiliently compressible material such as foam rubber.
• An end section 11 at each end of both rollers 6 and 7 is formed from a hard material.
• the end sections 11 are toothed into a gear like surface so that surface of each end section of one of the rollers engages the surface in the adjacent end section of the other roller.
• Rotation of a knob 8 rotates the roller 6.
• Rotation of the roller 6 in one direction by the knob 8 causes simultaneous rotation of the roller 7 in the opposite directions by the gear interaction between the rollers 6 and 7 at the end regions 11.
• the knob 8 is used to rotate the rollers 6 and 7 simultaneously in an insertion direction indicated by the arrows 30.
• An object 9 to be stored in the bin such as a soiled diaper or sandwich, is now placed between the two rolls of a film 3, over the rollers 6 and 7, as shown in Fig. 4.
• the knob 8 is then rotated so as to rotate the rollers 6 and 7 in the insertion direction and draw the bonded edge of film further into the container 1.
• the object 9 passes between the rollers 6 and 7.
• the material of the central region on both rollers 6 and 7 is temporarily compressed so as to allow the object 9 to pass between the rollers 6 and 7.
• crimping of the film 3 at the end sections 11 of the rollers 6 and 7 seals the two rolls of film 3 around the object 9.
• the two sheets of film are pressed against the object so as to prevent a significant amount of air from being trapped between the film 3 and the object 9.
• the two rolls of film 3 may be cut.
• the rolls of film 3 are preferably perforated at intermittent intervals to facilitate manual cutting of the film 3 by a user.
• the cut ends of the two sheets of film 3 wrapping the object 9 are then manually pressed together so as to bond the ends together. Further rotation of the rollers 6 and 7 by the knob 8 causes the object 9, now completely wrapped in the film 3, to be released from the rollers 6 and 7 and to fall into the container 1.
• the two sheets of film 3 are not cut after the object 9 has passed between the rollers 6 and 7 into the container 1. Instead, the two sheets of film 3 become bonded together above the object 9 as the film continues to pass between the rollers 6 and 7 after the object 9 has passed between the rollers 6 and 7. In this case, several objects may be wrapped together in the film 3 as shown in Fig. 1.
• Figs. 5 to 12 show a bin in accordance with a second embodiment of the invention.
• the embodiment of Figs. 5 to 12 has elements in common with the embodiment of Figs. 1 to 4, and similar components are referred to by the same reference numeral, without further comment or explanation.
• Figs. 5 to 12 has a lid 13 supported by two arched and toothed supports 15.
• the each support 15 engages a drive gear wheel 17 at a different end of the roller 6.
• each support 15 engages its drive gear wheel 17 in a rack-and-pinion mechanism so as to cause the drive gear wheel 17 to rotate in the direction of the arrow 28.
• An inner wheel 25 is rigidly fixed to an axle 26 of the roller 6.
• the inner wheel 25 supports a series of pawls 18.
• the pawls 18 are positioned so as to engage with teeth 27 on the inner surface of the drive gear wheel 17 in a ratcheted engagement.
• An object 9 to be stored in the bin such as a diaper or sandwich, is now placed between the two rolls of a film 3, over the rollers 6 and 7.
• the lid 13 is then closed so as to rotate the rollers 6 and 7 in the insertion direction and draw the bonded edges of film further into the container 1.
• the object 9 passes between the rollers 6 and 7.
• the material of the central region on both rollers 6 and 7 is temporarily compressed so as to allow the object 9 to pass between the rollers 6 and 7.
• crimping of the film 3 at the end sections 11 of the rollers 6 and 7 seals the two rolls of film 3 around the object 9.
• the two sheets of film are pressed against the object so as to prevent a significant amount of air from being trapped between the film 3 and the object 9.
• the lid 13 may be opened, and the two rolls of film 3 may be cut above the object 9.
• the rolls of film 3 are preferably perforated at intermittent intervals to facilitate manual cutting of the fihn 3 by a user.
• the cut ends of the two sheets of film 3 wrapping the object 9 are then manually pressed together so as to bond the ends together. Further rotation of the rollers 6 and 7 closing the lid 13 causes the object 9, now completely wrapped in the film 3, to be released from the
• the two sheets of fihn 3 are not cut after the object 9 has passed between the rollers 6 and 7 into the container 1. Instead, the two sheets of film 3 become bonded together above the object 9 as the film continues to pass between the rollers 6 and 7 after the object 9 has passed between the rollers 6 and 7.1n this case, several objects may be wrapped l o together in the film 3.
• a cover 14 may optionally be positioned at the rolls of film 3.
• the cover 14 has an aperture 21 in the cover 14 through which an object to be wrapped and stored in the container 1 is passed.
• the aperture 21 is positioned so as to position the object 9 over the central region 12 of the rollers 6 and 7 in order to achieve
