Sheet roller dispenser
View Patent ↗A sheet roller dispenser has a case with an interior for an accommodating space to receive a sheet roll. The case has an elongated hole longitudinally defined on a side face. An extension plate with a tongue extending upward is formed below the elongated hole at a central section of the elongated hole, and a corresponding pressing block is formed above the elongated hole to align with the extension plate. The sheet roll has a dotted line formed between two adjacent sheet units, and a slit is defined at a center section of the dotted line. When a free end of the sheet roll is pulled out from the case via the elongated hole, the tongue inserts into the slit of the dotted line to act as a stop, so that the pulled out sheet unit is separated apart from sheet roll easily and conventionally in operation by tearing along the dotted line.
1. A sheet roller dispenser comprising:
a case with an accommodating space for receiving a sheet roll, with the case having an elongated hole defined on a side face;
an extension plate with a tongue extending upward and having a width, with the extension plate formed on the case below the elongated hole; and
a pressing block formed on the case above the elongated hole to align with the extension plate;
with the sheet roll composed of multiple sheet units and having multiple dotted lines each between adjacent two of the multiple sheet units; wherein each dotted line has a slit having a width greater than the tongue with the tongue penetrating the slit, wherein a trim plate is formed inside the accommodating space near the elongated hole, with the trim plate located in the accommodating space and spaced from the elongated hole, the extension plate and the pressing block, with the trim plate having a free edge spaced below the elongated hole, the extension plate and the pressing block, with the sheet roll extending from the accommodating space intermediate the free edge of the trim plate and the case to the elongated hole, wherein the tongue extends upwardly from a free edge of the extension plate, with the tongue having an extent above the free edge of the extension plate, with the elongated hole having an extent in the side face parallel to the extent of the tongue, with the free edge of the extension plate being spaced from the elongated hole, with the elongated hole located intermediate the free edge of the extension plate and the accommodating space, with the extent of the tongue being greater than the extent of the elongated hole with the tongue extending from the free edge of the extension plate to the extent of the tongue beyond the elongated hole.
2. The sheet roller dispenser as claimed in claim 1 , wherein the case includes a first case body and a second case body pivotally connected at pivotal ends to allow the case to be open or closed operationally, with the trim plate and the pressing block connected to the second case body, with the extension plate connected to the first case body, with the trim plate extending from the second case body into the first case body; and
wherein a locking structure is formed at free ends of the first case body and the second case body opposite to the pivotal ends.
3. The sheet roller dispenser as claimed in claim 2 , wherein the first case body has an elongated cutout which turns into the elongated hole when the first case body and the second case body are combined.
4. The sheet roller dispenser as claimed in claim 1 , wherein the sheet roll defines an axis, wherein the pressing block includes a first plate extending away from the case parallel to the extension plate above the elongated hole and radially relative to the axis, a second plate extending from the first plate parallel to the tongue and spaced from the case, and the third plate extending from the second plate away from the case and beyond the tongue, with the third plate spaced from the case and having a free edge, with the tongue located intermediate the free edge of the third plate and the first and second plates.
5. The sheet roller dispenser as claimed in claim 4 , wherein the third plate includes a first section connected to the second plate parallel to and spaced from the extension plate and the first plate and a second section extending from the first section at an obtuse angle towards the tongue, with the first section being intermediate the second section and the second plate.
