Abstract: A print consumable may include a rotatable core, a roll of dispensable print substrate, and a radio-frequency identification (RFID) tag. The roll of the dispensable print substrate may be dispensably secured to the core. The RFID tag may be secured to the core and configured to rotate about a core axis. The RFID tag includes an RFID antenna coupled to an RFID chip. The RFID chip may include a print counter, a stock-keeping unit (SKU) code, and a consumable authentication code. A print system may include a housing, a holder to hold the print consumable, a print head, a transceiver, a trace antenna for reading an RFID tag of the print consumable, and a controller. The controller may be configured to receive a signal from the transceiver indicative of one or more of the print counter, the SKU code, and the consumable authentication code received from the RFID antenna.

Abstract: High opacity permanent ink formulations comprising a solvent, a polymer-based opacifier, a coloring agent, a resin, and a humectant, wherein the ink formulation displays a viscosity of less than about 50 cP, are provided herein.

Abstract: Reverse photochromic ink formulations containing at least one reverse photochromic colorant, methods of erasing reverse photochromic ink formulations by exposing them to UV light, and writing instruments including a writing tip portion connected to a light-shielding tubular member or refill and a reverse photochromic ink formulation are provided herein.

Abstract: Spinnable packages and package assemblies for products are provided. Spinnable packages include a base having a plate with a top surface and an opposed bottom surface, and a protrusion extending from the top surface of the plate. The packages also include a wheel configured to removably secure a plurality of products, the wheel having an aperture extending therethrough, wherein the wheel and the base are sized and shaped such that the wheel is spinnably mountable on the base when the protrusion is positioned in the aperture, such that the wheel is spinnable about a longitudinal axis of the protrusion.

Abstract: Reverse photochromic ink formulations containing encapsulated reverse photochromic colorant, methods of erasing reverse photochromic ink formulations including encapsulated reverse photochromic colorants by exposing them to UV light, and writing instruments including a writing tip portion connected to a light-shielding tubular member or refill and a reverse photochromic ink formulation including encapsulated reverse photochromic colorant are provided herein.

Abstract: Writing instruments with flexible nibs for reduced writing force in use are provided. A nib includes a nib body having a flexible upper writing portion and a lower portion in communication with the flexible upper writing portion, the lower portion of the nib body being configured to deliver ink to the flexible upper writing portion and the flexible upper writing portion being configured to deliver ink to a writing surface, wherein the flexible upper writing portion of the nib body has a flattened chisel-shaped tip at a superior end of the flexible upper writing portion, and wherein the nib is effective to deliver ink to the writing surface upon application of a force of less than about 0.1 lbs thereto.

Abstract: Compositions for use in writing instruments that provide for an opaque and permanent application and include a unique combination of a hollow particle component, a colorant, a viscosity modifier, a humectant, and an optional dispersant that result in shear-thinning properties.

Abstract: Ink formulations and associated writing instruments are disclosed herein. In some embodiments, an ink formulation is provided which includes an ink resin or polymer and a biobased solvent. In some embodiments, an ink formulation is provided which includes an ink resin or polymer and a solvent comprising at least one lactate ester.

Abstract: A sharpener for a writing instrument includes a receptacle, an entry assembly, and a cutter assembly. The entry assembly is coupled to the receptacle and defines an instrument opening. The entry assembly is configured to receive an end of the writing instrument through the instrument opening along an entry axis. The cutter assembly is configured to revolve about the entry axis in engagement with the entry assembly to sharpen the end of the writing instrument. The cutter assembly is removably engageable with the entry assembly at least by relative translation between the cutter assembly and the receptacle along the entry axis.

Abstract: Embodiments of the disclosure can include writing instruments, nibs for writing instruments, and methods of making the same. In one embodiment, the writing instrument includes a reservoir; an ink solution comprising a pigment, the ink solution being housed within the reservoir; a nib disposed at an end of the reservoir and plugging an opening of the reservoir such that the reservoir is closed, wherein a tip of the nib extends outside of the reservoir; and a filament extending within the reservoir, the filament being in fluid communication with a portion of the nib within the reservoir, such that the ink solution travels along the filament and through the nib, by capillary action, wherein the nib and filament are formed such that no more than 50 percent of the pigment present in the nib and filament flow into the reservoir outside of the nib and filament when the writing instrument is stored with the nib up for a period of one day.

Abstract: A print consumable may include a rotatable core, a roll of dispensable print substrate, and a radio-frequency identification (RFID) tag. The roll of the dispensable print substrate may be dispensably secured to the core. The RFID tag may be secured to the core and configured to rotate about a core axis. The RFID tag includes an RFID antenna coupled to an RFID chip. The RFID chip may include a print counter, a stock-keeping unit (SKU) code, and a consumable authentication code. A print system may include a housing, a holder to hold the print consumable, a print head, a transceiver, a trace antenna for reading an RFID tag of the print consumable, and a controller. The controller may be configured to receive a signal from the transceiver indicative of one or more of the print counter, the SKU code, and the consumable authentication code received from the RFID antenna.

Abstract: Package covers, assemblies, and methods of making the same are provided herein. A package cover is formed of a foldable paperboard blank that has a front panel, a rear panel, a tab extending from the front panel, and a shoulder connecting the front and rear panels, wherein the rear panel defines a notch configured to receive the tab therethrough when the blank is folded into a cover configuration, and wherein the front panel is printed.
