Definitions

• This invention relates to a dispenser for a roll of material, such as plastics material, foil or paper, said dispenser having opposing journal mounting means allowing rotation of the roll about it axis as material is dispensed therefrom.
• One object of the present invention is to provide novel means of inter-engagement between the roll and the journal mounting means of the dispenser.
• the present invention provides a dispenser for a roll of material in combination with said roll, said dispenser have opposing journal mounting means allowing rotation of the roll about its axis and also comprising a diaphragm which fits into or onto one of the journal mounting means so as to be rotatable relative thereto and which lacks an axial well or stub but is provided with a configuration of recesses and/or projections for engagement with corresponding projections and/or recesses at one end of the roll, and said roll having material wrapped around a core and, at one end at least, a bung which abuts or engages with the core and which lacks an axial stub or well but carries the corresponding projections and/or recesses for engagement with the diaphragm.
• the projections and/or recesses which inter-engage are primarily off-centre with respect to the diaphragm and/or the roll axis. In other words, although a portion thereof may pass through the axis in some embodiments, there is no axial well or stub as such on either the diaphragm or the bung.
• the other journal mounting means may conveniently be of cradle type in that it simply provides means for reception and support of the opposing end of the roll, or a shaft or similar projecting therefrom, enabling free rotation of said end, or shaft or similar.
• spring means may also be provided at this end to assist retention of the roll at this end.
• the diaphragm is of resilient material and is a snap fit into or onto the journal means.
• the diaphragm snap fit arrangement is preferably of such a design that once fitted to the journal mounting means the diaphragm cannot be removed without breaking.
• the diaphragm may be spring- loaded.
• the dispenser includes a container for the roll, which container has an interior surface provided with teeth or spikes or the like so that the material of the roll will tend to tear in the event that an attempt is made to pull material from the roll when the roll is not mounted upon the journal mounting means.
• a container for the roll which container has an interior surface provided with teeth or spikes or the like so that the material of the roll will tend to tear in the event that an attempt is made to pull material from the roll when the roll is not mounted upon the journal mounting means.
• journal mounting means are advantageously provided as parts of respective end mounts which engage with the container.
• These end mounts may engage with the container by a snap fit interconnection, and the design may be such that any attempt to disconnect the end mount once so connected would result in its breakage.
• the end mounts, whether connected by snap fit or otherwise, may advantageously include catch means adapted to secure a top or lid of the container.
• the bung projects, at least partially, from the end of the core and the material of the roll is wrapped around the bung as well as the core.
• the bung may be provided, around its exterior, with barbs to prevent its removal from the roll.
• the bung may also be formed in two parts, each part annular, which fall apart upon removal of the bung from the core so that the bung cannot be re-used.

• Figure 3 is a section of the same dispenser viewed along the line B-B in Fig 1;
• Figure 4 is a section of the same dispenser, viewed along the line D-D in Fig 1;
• Figure 5 is a fragmentary transverse cross-section showing roll mounting in another exemplary embodiment of the dispenser of the invention ;
• Figure 6 and 7 are fragmentary perspective views showing how the bung of the Figure 5 embodiment is mounted in a roll.
• Figure 8 is a perspective view showing how the bung of the Figure 5 embodiment engages with the spring loaded diaphragm.
• the exemplary dispenser comprises a trough shaped container (10) having a base (12) and front and rear walls (14, 16) and opposing end walls (18, 20) as well as a lid (22), which is shown only partially.
• Each end wall (18,20) is provided with a respective end mount or fitment (28, 29) which lies primarily inside the container (10) and has a portion (24) engaging in a corresponding aperture in the respective end wall (18, 20) and a portion (26) of cylindrical form providing journal mounting means for a roll of material (30) , which is to be accommodated within the container (10) and dispensed therefrom.
• a diaphragm (40) of resilient plastics material is a snap fit into the cylindrical journal mounting means (26) at one end (18) of the container (10), as shown in Fig 2.
• This diaphragm (40) is configured on its end face so as to have a recess (46) which is in the form of a letter "F" and a surrounding projection (44) defining said recess.
• the specific form of the projection(s) and recess(es) in the end face of the diaphragm are not critical to the invention. They may take any form, of letters, numerals, shapes, whether geometric or otherwise, stripes or dots, etc. The only requirement is that at least a part - or maybe all - of the configuration is off centre with respect to the diaphragm and/or the roll axis. In this way the dispenser can be customised for the rolls of any particular manufacturer.
• the diaphragm (40) is rotatable relative to the journal means (26).
• the other end fitment (29) has a closed end face to its cylindrical portion (26) and projecting therefrom is a U-shaped flange (27), best seen in Fig 4, which provides a cradle support for the other end of the roll (30) .
• the respective portions (24) of the end fitments (28, 29) are designed to make a snap fit connection with the respective end walls (18, 20) . Any attempt to disconnect the fitments (28, 29) is likely to result in their breakage.
• the end fitments (28, 29) also include upper portions (38, 39) which serve as catch means for securement of the lid (22) of the container (10) .
• catch means for securement of the lid (22) of the container (10) .
• Each end fitment (28, 29) is preferably formed integrally as a plastics moulding to incorporate the journal mounting means portion (26), the fitment mounting portion (24) and the lid catch portion (28, 29).
• the roll (30) is wound onto a core (32) , eg of cardboard or fibreboard.
• a cylindrical bung (34) engages as a push fit into the core (32) and projects therefrom, as shown in Fig 2.
• the material of the roll (30) is also wound around the projecting portion of the bung (34) and thereby holds it firmly in place at that end of the roll.
• An outer end face of the bung (34) is formed with a projection (36) which is configured as a letter "F” and sized to fit into the corresponding recess (46) in the diaphragm. In this way a non-rotatable connection is formed between the bung (34) and the diaphragm (40) .
• the core (32) projects and is able to rest in the cradle support (27) .
• the roll In use the roll is inserted by firstly engaging the bung (34) with the diaphragm, then dropping the other end of the core (32) into the cradle support (27) .
• the free end of the material on the roll is pulled out and dispensed via an opening between the housing (10) and its lid (22) or via any other opening provided for that purpose in any conventional manner.
• one or more reinforcing flanges (48) may be provided as shown in Figs 3 and 4.
• the bung may be formed in two part-annular parts and carry barbs to facilitate its retention by the material of the roll.
• the diaphragm and the end fitment may be differently configured, and the diaphragm could be spring-loaded by separate spring means to ensure that inter-engagement with the bung is maintained.
• spring loading at the cradle mount end may be provided to assist retention of the roll in its mounted position ready for dispensing of material therefrom.
• this second illustrated embodiment of roll dispenser may or may not have a similar container and similar end fitments to the first illustrated embodiment.
• a diaphragm (50) is shown which in use will be mounted in or on journal mounting means (not shown) at one end of the container and will be rotatable relative thereto.
• this diaphragm (50) can be springloaded by a compression spring (52) arranged between it and part of the mounting means.
• a compression spring arranged between it and part of the mounting means.
• other manners of springloading are possible.
• the roll (60) is wound onto a core (62) consisting of a tube of cardboard or fibreboard and at one end a bung (64) engages the core as a push fit and projects therefrom.
• the material of the roll (60) is wound around the core (62) and the projecting portion of the bung (64) at the same time.
• the bung is formed of two substantially part-cylindrical parts which are brought together upon the fitting of the bung (64) to the core (62) . When the wall of material is used up, these two parts come apart. Also, a shown, the bung (64) carries barbs (66) which serve to grip the material of the roll and prevent removal of the bung until the material is used up.
• Each half of the bung (64) is formed with a terminal flange (68) extending laterally and carrying a projection (69) which is sized to fit into a corresponding recess (59) in the diaphragm (50) , as shown in Figures 5 and 8.
• These projections (69) and recesses (59) are off-set from the axis of the roll and the centre of the disc-shaped diaphragm. As shown, the projections (69) have sloping faces so as to be able to slide across ramps (54) provided adjacent the recesses to gain entry to the recesses (59) in the springloaded diaphragm (50) .
• the roll (60) is mounted by firstly fitting the protruding end of the core (62) (at the end remote from the bung (64)) over a correspondingly sized projection (56) at that end of the container (see Figure 5) .
• the bung (54) is then engaged with the diaphragm (50) by the projections (69) thereon being pushed across the ramps (54) so as to counter the spring action of the diaphragm until they snap into the recesses (59) .
• Dispensing of the roll (60) is as previously described for the first embodiment and the container may also be provided with teeth or spikes, as in the first embodiment.
• the bung can be formed in one piece and the flanges and projections/recesses be differently configured.
• the bung which carries the projections and/or recesses corresponding with those on the diaphragm to allow for correct mounting of the roll may be simply inserted in one end of the core, possibly slightly projecting therefrom, without having any direct contact with the material which is wrapped around the core. In other words, in these cases the material will be wrapped solely around the core and will not assist in holding the bung in place.
