Singlehandedly operated dispenser for rolled sheets of paper

Abstract

The present invention refers to the singlehandedly operated dispenser for rolled sheets of paper for perforated and unperforated paper sheets alike. The spindle with roll of paper placed over-handedly is moving down and against the back wall along the chutes in the form of elongated slots, grooves or tabs in side walls and providing continuous contact of the outside surface of the paper roll with the back wall covered by antiskid layer, and thus keeping the roll of paper immobilized and in fixed position against the back wall, and preventing run-off when the amount of paper on the roll is getting smaller. Drawing sheet of paper upward from the roll disengages the roll from the back wall, while drawing downward increases engagement of the outside surface of the roll with back wall that allows separating the required length from the roll leaving previously separated edge on top of the roll for easy access at next draw.

AI Technical Summary

Benefits of technology

[0014]control rotation of paper roll to prevent unwinding and spinning while pulled;

[0016]keep the full width of previously separated paper easily and safely accessible irrespectively of the amount of paper remaining on the roll;

[0019]Apparatus disclosed hereby utilizes chutes, stoppers, and spindle to control operation and position of paper on the roll. The dispensing apparatus has a back wall and two side extensions perpendicular to the back wall in the same direction. Stoppers and chutes are derived either from cutouts in side extensions or made by extending inward peripheral edges of inside faces of side extensions. Chutes that are tilted to the ground in 45 degrees allow paper roll on the spindle to glide gravitationally down and always to rest against the back wall, while stoppers located at the top end of chutes prevent separation of the spindle from the dispenser when paper is excessively pulled too far out.

[0020]Dispenser's base has back wall that is covered with antiskid layer to enhance interaction of the paper surface with back wall during separation of desired length of paper. Peripheral edges of lower corners of side extensions are substantially chamfered in 45 degrees angle while leaving the remaining upper corners of peripheral edges untouched.

Problems solved by technology

Each attempt lacks whole solution for the problem and fails at separating material in unperturbed way, and to work well without additional restrictions in respect of the quality and kind of rolled material, especially while using one hand for drawing desired length of material from the roll.

In applications where the rolls of paper are pre-perforated in production process, paper holders are equipped with attachments restricting free spin of the paper roll but fail towards the end of use when paper on the roll depletes and two hands are required to separate the paper from the roll.

Other applications utilizing electronically controlled dispensing operation are inconvenient and impractical in home environment, taking space, energy, and financial resources.

Such dispensers do not operate without electrical power and the roll is completely immobilized inside the container without possibility to reach the material by hand during power shortage.

The applications that allow also manual dispensing without power supply are failing in holding the roll of material in stationary fixed position for effective dispensing and eventually require the use of both hands.

Rolls of paper towel and toilet paper usually perforated while pulled by one hand unwind uncontrollable or even run completely off the dispenser.

Whereas dispensers for paper towels take counter space in the kitchen and fail to work correctly.

While at the beginning of the roll it is possible to draw only one sheet after fumbling for the edge of previously torn towel, at the end of the roll, when the diameter of the roll is reduced, the said dispenser is not functioning at all.
