10 Claims.

This invention relates to improvements in interfolded paper dispensers.

It is the principal object of the invention to provide a paper dispenser wherein a web of paper previously withdrawn from the interfolded pack within the dispenser case will extend free of the dispenser side panels so as to present a projecting portion which may be readily grasped for the purpose of its complete withdrawal. In this connection it is an object of the invention to provide a paper dispenser. having edged surfaces adjacent a dispensing slot so oriented as to hold the projecting paper web away from the dispenser side surfaces.

Another object of the invention is to provide a paper dispenser having an internal follower plate construction permitting the interfolded sheets to be readily pulled from the dispenser without binding against the remaining sheets or otherwise disturbing the interfolded relation of the remaining sheets.

Another object of the invention is to provide an interfolded paper dispenser having a follower plate movable to and from a paper dispensing slot on improved channel support and guide elements.

Another object of the invention is to provide a paper dispenser having an improved paper loading door which is held in normally closed position by the weight of the dispenser itself.

Other objects wll be more apparent from an examination of the following disclosure.

In the drawings:

Fig. 1 is a front three-quarter perspective view of the dispenser with a portion of the front of the loading door broken away to show details of interior construction.

Fig. 2 is a plan view largely in cross section along the line 2-2 of Fig. 4 with portions broken away to show further details of construction.

Fig. 3 is a cross sectional view taken along the line 33 of Fig. 2.

Fig. 4 is a cross sectional view taken along the line 4-4 of Fig. 2.

Fig. 5 is a perspective View of the follower plate disassociated from the dispenser.

The paper dispenser is designed to store in readily accessible form a pack ID of interfolded paper sheets. The various interfolded sheets comprising the pack progressively become individually accessible as the next preceding sheet is withdrawn from the dispenser through a slot 13. By virtue of the interfolded relation of succeeding sheets, withdrawal of one sheet automatically brings the next succeeding sheet into projecting relation through the slot whereby its extending Web i I may be readily grasped for the purpose of its withdrawal.

The dispenser comprises a case [2 which is provided at one side surface with a longitudinal dispensing slot l3 through which the webs ll of the interfolded pack progressively extend. The case i2 is provided with a paper loading door indicated generally as it; which forms the lower front corner of the case comprising the lower portion l8 of the front of the case and the front portion I! of the case bottom. The door is swingable to an open pack loading position on hinges 20 which are secured to the fixed portion IQ of the case bottom.

The door It projects forwardly of the plane of the upper front case surface 23 a distance equal to the width of the top marginal edge 24 of the door front Hi. The marginal edge 24 is continued at right angles to itself to form an inner flange 25 parallel to the front [8. An abutment 26 is struck up from the bottom of the door I! to be substantially co-planar with the flange 25, both flange 25 and abutment 26 being substantially co-planar with the upper front surface 23 of the case. The lower edge of front surface 23 is rolled inwardly and upwardly back against itself so as to provide an abutment flange 21.

The interfolded paper pack H! may be inserted through the open door into the case and positioned as best shown in Fig. 4. The closing of the door leat'es the front of the pack abutting the upper flange 2! and the lower door abutment 26. When so inserted within the case the interfolded paper pack is constantly pressed against the flanges 26 and 21 by means of a follower plate 28 which backs up the pack and is slidable toward and away from the dispensing slot It. The follower plate 28 is'provided with a coil spring 29 which normally biases the plate toward the slot. The rear inside surface of the case is provided with an embossed circular abutment 30 which provides a seat upon which the coil spring 29 is located. The end of the coil spring remote from the abutment 3c is engaged with the nibs 33 struck from the rear of the follower plate 28.

With the interfolded pack IE3 so inserted a projecting web of one of the interfolded sheets will extend outwardly of the dispensing slot it. As successive sheets are dispensed the web will project alternately from the top or the bottom of the case, as shown in the dotted and full lines 3i and 32, respectively in Fig. 4. When the web I extends from the bottom of the case as at 32, it

When the web extends from the top of the case, as at 3|, it is held away from the front surfaces of the case by the outward offset of the lower margin 24 of the dispensing slot and is similarly free of the case surfaces and in a convenient position to be grasped by a user.

In order to support and guide the follower plate in its sliding movement, the case i2 is provided with inwardly flanged channels disposed at the insidesurfaces of the case end panels. The channels comprise inwardly extending

flanges

34 and 35 which extend from front to rear of the case and terminate inside the front of the case, immediately adjacent the sloted'ges. The horizontal face of the lower flange 34 is extended, as best shown in Fig. 1, to the outwardly offset surface of the case l2 below the .slot so .as to give apparent thickness to the wall ofthe case below the slot.

The follower plate 28 is provided at its side edges with

guide fingers

36 and 31 which extend at substantially right angles to the plane of the follower plate and which are spaced from each other complementary with the channel flange spacing so as to peripherally engage the inner surfaces of the

guide flanges

34 and 35.

Although the fit between the

guide fingers

36 and 31 and the channel flanges 34 and is sufficiently loose to permit ready sliding of the follower plate along the channel, the lateral extension of the fingers 3B and 31 is sufllciently long to maintain the follower plate in substantially a vertical position within the case.

The shape of the follower plate is ofsome considerable significance. It is noted that the plate is concavely dished in a direction away from the slot so as to present a cavity 38 between the follower plate and the rear sheet of the paper pack Hi. This cavity 38 is located at the lower portion of the plate 28 so as to be disposed relatively adjacent the abutment 26 against which the paper pack is frontally confined. The withdrawal of the front interfolded sheet from pressure contact with the abutment 26 will cause a binding pressure to be exerted laterally of the pack at its lower portion when the next succeeding sheet folded therewithin is curled upwardly. This lateral pressure will be readily absorbed by slight pack deformation into the cavity 38. Inv this manner the smooth withdrawal of the first sheet and the front web of the sheet interfolded therewith is insured while succeeding sheets are firmly held. The upper portion of the plate 28 need not be provided with a similar cavity, as the upper forward portion of the pack [0 is not rigidly confined; thus lateral distortion of the top of the pack will take place for wardly of the front interfolded sheet.

The case is provided with longitudinally paired

feet

39 and 40. The feet 39 are disposed at the fixed bottom portion IQ of the case at one side of the hinges 20, and the feet 40 are disposed in the hinged bottom portion I! of the door 16 at the other side of the hinges 20 The weight of the case pressing downwardly on both sets of paired feet will normally hold the door [6 in closed position, although the case may additionally be provided with a detent holding means (not shown).

From the foregoing description it may be seen that the paper dispensing case having a forwardly projecting portion below the dispensing slot serves to hold a downwardly projecting paper web away from the case front surfaces so as to permits the free and unbinding removal of the several successive interfolded sheets. The hinged door provides a convenient and simple means for loading the case, and the disposal of the feet fore and aft of the hinge line provides for gravity biased closure of the door. In addition the follower plate is provided with an improved means for its support and guidance as it progressively urges the sheets, toward the dispensing slot.
