A tool-hanging apparatus includes a hanger and a rotor. The hanger includes a ring, an inward flange formed on a rear internal section of the ring, and teeth formed on a front internal section of the ring. An internal diameter of the inward flange is smaller than a diameter of a circular defined by the teeth. The rotor includes elastic strips extending from a tube. Each of the elastic strips includes a groove between a ridge and a barb. One of the elastic strips includes a tooth extending from the ridge of the same. When the rotor is inserted in the ring, the grooves of the elastic strips receive the inward flange to keep the rotor in the ring and allow the rotor to rotate relative to the ring. The tooth is engageable with the teeth to keep the rotor at an angle relative to the ring elastically.

A payment card includes hidden features (e.g., textual messages, graphics, emphasis features associated with conspicuous features of the payment card, or the like) undiscernible under only visible light, but discernable under ultraviolet light. The hidden features can be incorporated into multiple layers of a side of the payment card and can be present with different transparencies, different colors, and different persistence.

A payment card includes hidden features (e.g., textual messages, graphics, emphasis features associated with conspicuous features of the payment card, or the like) undiscernible under only visible light, but discernable under ultraviolet light. The hidden features can be incorporated into multiple layers of a side of the payment card and can be present at different transparencies. The hidden features, applied during manufacturing, can be i) selected (e.g., randomly or sequentially) from an available hidden features list; ii) supplied by user input; and/or iii) selected based on a user's previous hidden feature(s) (e.g., the same as or different from the previous hidden feature). A quality check can include comparing an image of the payment card illuminated under ultraviolet light with the selected hidden feature(s).

The present disclosure relates to a pH-sensitive indicator label using a pH-sensitive color-changing ink composition, and a packaging material, the pH-sensitive indicator label including: a pH-sensitive color-changing ink composition layer including a pH-sensitive color-changing ink composition; a first film on which the pH-sensitive color-changing ink composition layer is formed; and a second film laminated onto the first film to cover the pH-sensitive color-changing ink composition formed on the first film. The pH-sensitive color-changing ink composition of the pH-sensitive color-changing ink composition layer includes a pH-sensitive indicator prepared by mixing a plurality of pH color-changing dyes of which colors change according to the pH ranges thereof and a dissolving ink capable of dissolving the pH-sensitive indicator. The packaging material includes a container into which a product is inserted, a through hole passing through the container in a region not in contact with the product, and a label attached to the through hole.

A container includes a bottom box and a top lid. The bottom box includes a containing space adapted to contain the contents. The bottom box has a tilted shape wherein the bottom box has one side height greater than another side height. The top lid includes an integrally formed lens and formed with a plurality of air holes on a top surface thereof. The top lid is removably assembled with the bottom box.

A weight sensing cooler assembly includes a cooler that is comprised of a thermally insulating material for storing cooled beverages. A scale is movably integrated into the cooler for measuring the weight of the cooler. Moreover, the scale compares the weight of the cooler against a pre-determined baseline weight to determine the number of cooled beverages in the cooler. A display unit is coupled to the cooler wherein the display unit is configured to be visible to a user. The display unit is in electrical communication with the scale thereby facilitating the display unit to display a visual representation of the number of the cooled beverages in the cooler. In this way the display unit can communicate the number of cooled beverages to the user.

A packaged laundry product comprising a flexible package and a plurality of perfume-containing particles contained in the flexible package. Said packaged laundry product comprises perfume-containing particles which contains a carrier; and a perfume; and wherein each of said particles has a mass between 1 mg to 1 g, and has a maximum dimension of less than 10 mm. The flexible package is made of a layered film material and comprises a top end, an opposing bottom end, and two peripheral walls extending between the top end and the bottom end, wherein at least one or more parts of the flexible package is transparent or translucent. The flexible package is characterized that the bottom end of the flexible package comprises one or more holes.

Aspects of the present invention disclose and describe embodiment containers for displaying, visualizing, and aroma sampling botanical material—such as tea, cannabis, and the like including a container body, lid, and lens—which may have various shapes. In a preferred embodiment, lid is shaped to define a recessed area with scent openings permitting aroma sampling of a sample contained within. A removable plug is shaped to fit within the recessed area of the lid. The container body and lid, with removable plug fit within the lid, form an airtight chamber within. A botanical sample may be visualized through the lens.

A device for storing oil or another vaporizable substance can include a porous body adapted to absorb a volume of liquid and to retain the volume of liquid for vaporization. A porous body can include a matrix of pores adapted to take up and retain oil by capillary action. A method of vaporizing oil can include storing the oil in a porous body and heating the porous body.
