Abstract

A dispenser for dispensing a web of material spirally-wound about a bore includes a housing which supports a pair of members at spaced locations Each member includes an opening for receiving and frictionally engaging with a cylindrical, plastic insert placed in the bore. The plastic inserts frictionally engage the bore for rotation with the web of material. A
passageway extends upwardly from each opening to permit insertion of the plastic inserts into the openings. The passageways are narrower than the openings to maintain the plastic inserts in the openings.

Description

1 33728~

The present invention relates to a di~pPn~Pr for dispensing a web of matPri~l from a spirally-~und roll of such m~t~Pri~l.

It is common to ~i~pen~P~ web m~teri~l from a container mounted at a convenient location such as a wall. The web m~tPri~l may be a paper towel supplied as a roll and requiring replacement from time to time as the rollof paper towel is used. Such ~ pen~prs must not only be sturdy but must also be able to dispense the web m~teri~l in a controlled manner to avoid wastage and offer m~ximum convenience for the users.

There have been a number of approaches to fii~pen~Prs of this nature but most have utilized relatively complicated mech~ni~m~ to control the supply of web m~tPri~l from a roll. Others require a relatively complicated procedure to replace the roll or inhibit access to the ~lispen~p~r during such replacement.

It is therefore an object of the present invention to provide a novel dispenser which obviates or miti~tPs at least one of the above-identified disadvantages.

According to one aspect of the present invention, there is provided a dispenser to dispense a web of m~tPri~l spirally-wound about a central bore, said dispenser comprising:
a housing;
a pair of generally cylindrical projections adapted to extend from and frictionally engage opposite ends of said bore in a manner to inhibit relative movement between said web of m~tPri~l and said projections; and ~' B

a pair of support members secured to said housing at spaced locations, each support member having an opening therein with a peripheral wall to receive a respective one of said projections, and a passageway extendingupwardly from said openillg to the exterior of said support member to permit insertion of a ~ e one of said projections in said opening, said passageways being na~r~v~;l than said openings to ",~in~i.in said projections insaid openillgs, said peripheMl walls frictionally eng~ging said projections to impart drag thereon during movement of said projections relative to said support members.
PrefeMbly, each of the projections is tubular and passes through the passageway by flexure of the walls of the support member. This permits convenient replacement of the web of m~tPri~l while providing for a simple construction to m~int~in control of the t~i~pencing of the web of m~tlori~l.
It is also pl~rt;lled that each projection is formed on an insert having a flange to limit movement of the insert into the bore.

An embodiment of the present invention will now be described more fully with reference to the accolllpallying drawings in which:
Figure 1 is a geneMI perspective view of a dispenser;
Figure 2 is a front elevation of the dispenser shown in Figure 1 with portions removed for clarity of illustr~tion;
Figure 3 is a view on the line 3-3 of Figure 2 with a roll of web m~teri~l shown in chain dot line for clarity;
Figure 4 is an enlarged view of a portion of the dispenser shown in Figure 3 illustrating ~ ive positions of colllponents of the dispenser;

1 337~89 Figure 5 is a view of the underside of the dispenser shown in Figure l;
Figure 6 is a view on the line 6-6 of Figure 5;
Figure 7 is a view similar to Figure 6 showing the (lispen~pr in an ~ltPrn~tP, position; and Figure 8 is a view on the line 8-8 of Figure 4.

RPf-Prlin~ now to Figure 1, a ~ pçn~Pr is shown and is generally indiç~tPd by reference numeral 10. The dispenser 10 include~ a housing 11 having a base 12 and a lid 14. The base 12 includes a pair of upstanding sidewalls 16 int~l~o~ P~t~P~ by a rear wall 18 and a floor 20. Projecting upwardly and îol~d~dly from the floor 20 is a lip 22 forming a front wall.

The lid 14 has an upper curved panel 24 in~Pgr~lly formed with a pair of side panels 26. The lid 14 is pivotally mounted for movement about a horizontal axis by pivot pins 28 that extend between the upper rear corners of the sidewalls 16 and the side panels 26 respectively.

As can best be seen in Figures 2, 3 and 4, a support member 30 is mounted on the interior face of each sidewall 16. The support members 30 are secured to the sidewalls 16 by intPgr~lly molded clips 32 that pass through apel~ules 34 formed in the sidewalls 16 (see Figure 8). Each support member 30 has a centrally located opening 36 with peripheral sidewalls 38 d~Pfining theopening 36. The openings 36 form the major portion of a circle. A
passageway 40 extends from an upper edge 42 of each support member 30 to the opening 36 and has a pair of convergent sidewalls 44.

, B

Each of the support members 30 is adapted to support a ;speclive one of a pair of tubular plastic inserts 46. RPf~prring now to Figures2 and 4, one of the inserts 46 is illll~tr~tP~. As can be seen, each insert has a cylin-lrit ~l projection 48 encomp~P~ by the peripheral sidewall 38 of one of S the openillgs 36. The sidewalls 38 and the projections 48 are (1imPn~inned so that the projections 48 fit tightly within the openings 36 causing the sidewalls38 to engage frictionally the projections 48 and retard, though not inhibit, rotation of the inserts 46 relative to the support members 30. Each insert 46 also includes a radial flange 60 and a tubular tapered boss 62. Eight ribs 64 project radially from the boss 62. The boss 62 of each insert 46 is adapt_d to fit tightly into an opposite end of a bore 70 at the core of a spirally-~und roll of web m~teri~l 72. The bosses 62 engage frictionally the interior of the bore 70 so that they rotate with the roll of web m~tPri~l 72 rather than the roll of web m~tP.ri~ laling on the inserts 46. The flanges 60 limit axially movement of the inserts 46 in the bore 70 to ensure an applupliate spacing between the cylindrical projections 48 at each end of the roll of web m~tPri~l 72. For convenience, the inserts 46 are supplied with the roll of web m~tPri~l 72.

When the roll of web m~tPri~l 72 is mounted in the housing 11, the m~tPri~l from the roll passes bt;lween the front panel 24 and the leading edge of the lip 22. The lower edge 76 of the front panel 24 is serrated to facilitate separation of portions of m~tPri~l from the roll of web m~tPri~l 72.

The lid 14 is secured in a closed position shown in Figures 1 and 2 by a latch device acting between the lid 14 and the base 12. As may best be seen in Figure 5, the lower edge of each side panel 26 is formed with an inwardly projecting tab 80. The tabs 80 are received in recesses 82 formed by notches in the sidewalls 16 and floor 20. As shown in Figure 6, with the lid B

14 fully lowered, the tabs 80 are engaged in the recesses 82 to prevent upward mavement of the lid 14 about the pivot pins 28 when m~ter1~l is sep~ P~I along the SP~tP,d lower edge 76.

S The tabs are also operable to Ill~in~i,in the lid 14 in an open position by çng~ing the upper edges 88 of the sidewalls 16. In this position, the lid 14 is held in an elevated open position allowing access to the interior of the housing 11 (see Figure 7). The side panels 26 are suffl~iPntly flexible to allow the tabs 80 to be moved out of the recesses 82 in the direction of arrow 90 and pass along the sidewalls 16 when moving the lid 14 belween the closed and opened positions. The resilience of the side panels 26 causes the tabs 80 to return to a position in which they overlap the upper edges 88 once the tabs 80 have cleared the top of the sidewalls 16.

To load the ~ p~Pn~Pr 10 with a roll of web m~tPri~l 72, the lid 14 is moved to the opened position as shown in Figure 7. The roll of m~tPri~l 72, with the inserts 46 fitted tightly in the ends of the bore 70, is inserted into the housing 11 with each projection 48 resting on the convergent sidewalls 44 of one of the passageways 40. The roll of m~tPri~l 72 is then pushed down causing spreading of the sidewalls 44 and entry of the projections 48 into the openings 36 (see Figure 4). The openings 36 and projections 48 are ~lim~pnsioned so that the peripheral sidewalls 38 of the openings frictionally engage the projections 48 to impart drag on the projections 48 as the plastic inserts 46 rotate. l~tPri~l from the roll is then fed over the lip 22 and the lid 14 is moved to the closed position by oulward movement of the side panels 26.
This allows the tabs 80 to (li~Png~ge from the upper edges 88 of the sidewalls 16 and the lid 14 to be returned to the closed position in which the tabs 80 B

engage the lccesses 82. Remaval of the roll of web m~tPri~l 72 is simply the reverse of the aba~e.

In operation, the drag imparted on the inserts 46 permits m~tPri~l S from the roll of m~tPri~l 72 to be ~ pcn~ in a controlled manner and avoids the inertia of the roll ~ispPn~ing an excess qu~ltily of m~tPri~l. Remaval of the inserts 46 from the bore 70 is straight-r~lwd~ and may be accomplished without any specific tools or skills.

The base 12 and lid 14 may be integrally molded from a plastics m~tPri~l allowing a very simple and inexpensive mode of construction.
Similarly, the support members 30 and plastic inserts 46 may also be molded from plastics m~tPri~l to provide the nP~ry control over tolerances and the friction fit. Typically, an inlclrclellce fit of 0.025 inches is provided bclwcen the projections 48 and the openillgs 36. The support members are suitably formed from a plastics m~tPri~l that exhibits high wear char~c~ri~tics such as nylon.

It will be seen therefore that a dispenser is provided which is simple to operate and manufacture.

It will be appreciated that the inserts 46 could be replaced with a tubular roller having an inlc~cnce fit within the bore 70.
