Abstract: A hygienic dispensing package includes a container having a top panel with a dispensing aperture selectively covered by a slide closure. The closure rides within a flat channel of the top panel and is in tongue and groove engagement with parallel side walls of the channel. One of a pair of spaced sockets in the channel is engaged by a detent formed on the underside of the closure when the aperture is covered; the detent seats in the other socket when the aperture is uncovered. The detent is formed as a protrusion on an integral cantilever leaf of the closure to assure intimate sliding contact between the faces of the channel and the closure and effective sealing of the aperture.

Abstract: A cutter for cutting a pattern in a substrate, said cutter having a base and guide pins disposed on the bottom of the base. The guide pins are placed in a groove on a template. A longitudinally adjustable member supports a blade unit for cutting the pattern into the substrate, where the adjustable member is configured to be slidably positioned within a center track opening region movable towards and away from the guide pins.

Abstract: An ellipse drawing/cutting device is made up a base plate, a driving gear, a coil spring, a driven gear, a position retaining arm, a compression spring, a longitudinal measurement disc, a first fixing ring cover for the longitudinal measurement disc, a lateral measurement disc, a second fixing ring cover for the lateral measurement disc, a slide bracket assembly including a ruler frame, a pair of slide wings and cover two plates; a link bar, a plurality of anti-slip blocks disposed under the base plate, and a plurality of differently spaced pen insertion holes are distributed on the ruler frame which is relatively slidable on the lateral measurement disc.

Abstract: A toilet bowl in combination with a pressurized flush tank is presented wherein the pressurized tank has a spring, a float piston, a water inlet control valve set, a water discharge control unit and a container lid. The water inlet control valve set includes a valve unit, a valve cover, a small spring, a control piston, a seal ring, a float and a control wire. The water discharge control unit has a control handle, a link bar, a seal ring, two link bar fixing seats, a seal cap and a set of discharge fixing ring. When water is discharged, the compressed spring applies a force to the float piston so that the float piston will exert pressure on water which rushes into a toilet bowl as a result.

Abstract: An improved circle drawing tool is equipped with a doughnut-shaped outer board, a circular slide track mounted onto the outer board and an inner circular board provided with rolling balls in a plurality of receiving cavities thereof and having such a diameter that it can be rotarily engaged with the slide track as well as the doughnut-shaped outer board in assembly. On the doughnut shaped outer board are disposed a plurality of round holes distributed one by one consecutively according to their diameters. The are 4 straight lines separated apart at 90 degrees in angle. There are a number of small pen insertion holes consecutively spaced by 4 mm on each line and each starting point of the four lines is 1 mm farther away from the center of the outer board. There are 10 radial lines equally divided on the inner circular board. On each radial line there are a plurality of consecutive pen insertion holes defined thereon with every two neighboring points 10 mm spaced apart.

Abstract: A circle cutter, particularly a cutting instrument, is adapted for cutting circles on objects. It includes a rotary disc assembly and a cutting tool. The rotary disc assembly is made up of an outer ring board, a rotary disc, a fixing ring cap and a plurality of beads. The rotary disc mounted to the outer ring board is movably limited in place by the fixing ring cap and are rotatably supported by the multiple beads received in a tunnel defined between the outer ring board and the rotary disc. On the rotary disc are disposed a plurality of holes marked with a numeral that is the diameter of a circle to be cut. The cutting tool has a hollow pen stick and a cutting knife attached to a knife clip that is movably engaged with a holding head. The holding head is further secured to the bottom end of the hollow pen stick and is free to rotate with respect to the pen stick so that the cutting knife can be smoothly guided in a cutting operation.

Abstract: A file clip having a punching function, includes a base board, a paper hanging member, a leaf spring for fixing the paper hanging member, a paper clip member, two locating springs for locating the paper clip member, a wave spring, two punching rods, two extension springs and two transparent plastic caps. The base board is formed with a pivot channel for pivotally receiving the paper hanging member that has two punching sections at two ends and a middle lug section. A fixing dent is formed in front of a fixing recess which is formed at an upper middle section of the base board for fixing the paper hanging member. Two fixing holes are formed on the rear end of the base board for fixing the file clip. A notch is formed at a middle section of the front end of the base board. Two locating channels are on both sides of the notch for pivotally connecting the paper clip member. Two punching seats extend downward from each punching hole that is formed on the base boards.
