Improved systems and methods for medicine delivery, and in particular, improved insulin pen needles and related devices are provided. Smart injection devices record and transfer data including medicine level, delivered dose, dose confirmation, and dose time and date. Additional data captured may include glucose concentration, insulin level, carbohydrates ingested, stress level, exercise, blood pressure, and glucose high and low excursion events. Various means of data collection and analysis are provided and systems can identify and flag patients who require intervention. Smart sleeves and add sensing capability to standard insulin pens. Pen needles are provided with sensing capability to confirm and measure doses delivered by insulin pen. A two-part pen cap include a primary sleeve that connects to the insulin pen and an end cap that provides for capturing the time of dose delivery, and monitoring the hold time for a dose delivery after plunger movement.

A roller spreading device for spreading a butter substance over a food product is provided. The device includes a basin structure and a roller member. The basin structure is sized to hold the butter substance for melting therein, the basin structure including a lower floor surface extending with an arcuate structure. The roller member includes a cylindrical outer surface with multiple recesses therein sized to capture the butter substance along the multiple recesses. The roller member, suspended within the basin structure, rotates about an axis such that the roller member rotates through the butter substance pooled along the arcuate structure.

A composite thermoformed tableware and preparation method thereof. The preparation method involves a preheating step, a compositing step and a thermoforming step in sequence; the preheating step heats multilayer forming materials at a temperature of 35° C. to 150° C., the forming materials have one or at least two of paper, plastic and inorganic layer; the compositing step involves stacking the preheated forming materials to form a composite material; the thermoforming step involves heat-pressing the composite material at a temperature of 80° C. to 150° C. and a pressure of 0.05 MPa to 0.5 MPa to form a three-dimensional body. The tableware is thermoformed by multiple layers of the same material or different materials, so that the thickness and strength of the tableware are higher.

Provided herein are methods and compositions comprising a non-toxic ferromagnetic ink composition. Also provided herein are plastic objects containing a surface coating of a food-safe ferromagnetic ink composition. The coating imparts functionality to a plastic object such that the object is capable of being mechanically separated from waste stream using a commercial magnetic separator. The food-safe ink composition, which can be printed using high-speed flexographic, intaglio, offset printing or pad printing, combined with heat transfer printing or hot foil stamping consists of an ingestible magnetically susceptible pigment capable of rendering the printed template with magnetically active properties. The surface of the plastic object described can consist of geometric designs which increase printable surface area without significant changes in dimensions of the said object.

The present invention relates to a handheld tool to facilitate removing of an eggshell from a hard-boiled egg quickly and safely without damaging the egg and creating a mess. The tool includes a longitudinally extending handle, a peeler portion having a top concave surface and a bottom convex surface, a fin protrusion attached to the bottom convex surface, and a neck positioned between the handle and the peeler portion. The fin protrusion is used for tapping the eggshell of the hard-boiled egg to crack the eggshell and the peeler portion is configured to insert underneath the eggshell and to move along an exterior of the hard-boiled egg for removing the eggshell therefrom. The tool removes the eggshell quickly within ten seconds without breaking the eggshell into tiny pieces.

Disclosed herein is a method for preparing a low-cost fully-biodegradable plant fiber starch tableware. A plant cellulose material containing dregs of Scutellaria baicalensis is modified to obtain a modified plant fiber starch blank. Konjac gum is subjected to pulverization and ultrafine pulverization to obtain a colloidal binder combined with a deacetylated konjac gum. The colloidal binder is mixed with the modified plant fiber starch blank to obtain a mixture. The mixture is subjected to foam molding in a forming mold to obtain the low-cost fully-biodegradable plant fiber starch tableware.
