Among other things, one or more systems and/or techniques for labeling a refill contain and/or for enabling operation of the refill container by a dispensing system based upon one or more indicia of the label satisfying a dispensing key are provided. In an example, a label may be applied to a refill container. The label may comprise a first region having a first indicia that may correspond to a shape, color, and/or texture (e.g., a yellow star indicia). A dispensing system may enable operation of the refill container (e.g., installation and/or dispensing of material from the refill container) based upon the first indicia satisfying a dispensing key (e.g., a yellow key component and/or a star shape component). Otherwise, the dispensing system does not enable operation of the refill container (e.g., the refill container is not genuine or is not an appropriate refill container type).

A tamper evident tag is provided having a sealant layer, and ink layer and an oxygen barrier layer. The tag may be a film-based tag incorporating a color shifting ink layer located in the sealant layer and a bar code in the ink layer. The tag may be placed over one or more perforations in the bottom end covering of a container. When the container is opened, air enters the interior of the container, passes through the perforations and into the sealant layer. When air reaches the color shifting ink layer, it changes to a color the same as or similar to the bar code, rendering the bar code illegible.

A label to identify an object has an inscribable layer composite for receiving a first, visible inscription to identify an object, an adhesive film for adhering the label to an object, and an active substance, which, when contacting the object surface, penetrates into and/or acts on the object surface. The active substance is disposed on the label rear side in a structured active surface layer, on, in, or underneath the adhesive film. The structured active substance layer includes a partial surface region or multiple partial surface regions of the label base surface. When the label is adhesively affixed to the object surface, the active substance on the label rear side selectively contacts the object surface in the structured active substance surface region. Within the base label surface, the structured active substance layer has the shape and/or contour of a further, initially-invisible inscription, identification or item of information.

Disclosed are various embodiments of multi-layer identifier labels. In one embodiment, a multi-layer identifier label includes an upper layer bearing a public identifier, a lower layer bearing a private identifier, and an adhesive backing below the lower layer. The upper layer may be removably attached to the lower layer, and the lower layer may be non-visible underneath the upper layer. Peeling away the upper layer to reveal the lower layer may be a tamper-evident action.

An ink that is detectable using infrared (IR) light may be used to apply machine readable codes, such as a barcode. The indicia, once applied, may be either invisible or difficult to detect with visible light, such as with the human eye. The ink may include one or more materials such as titanium dioxide (TiO.sub.2), particles of acrylonitrile butadiene styrene (ABS), metals, and so forth. These materials may be used to enhance one or more of the reflectivity to IR light or the fluorescence of the ink under IR light. The fluorescent ink may be deposited in a single pass, or as part of a two-pass process in which a reflective substrate, such as a resin with encapsulated TiO.sub.2, is applied and then the fluorescent ink is deposited atop the substrate. The markings are machine readable even when overprinting markings that are readable under visible light.

A combined primary label and secondary label comprises a first piece of paper, a first release coating disposed on a portion of the first piece of paper, a second piece of paper, a second release coating different from the first release coating and disposed on a portion of the second piece of paper. The combined primary and secondary label further comprises an adhesive layer disposed between the first and second pieces of paper such that (i) a primary label can be peeled away with at least some adhesive of the adhesive layer from the second release coating disposed on the portion of the second piece of paper, and (ii) a secondary label can be peeled away with at least some adhesive of the same adhesive layer from the first release coating disposed on the portion of the first piece of paper.

A label is provided with a warning layer coating integrated or applied to a front side of the label. The warning layer coating is not activated by application of heat; rather, the warning layer coating activates upon a directional force (vertical or horizontal puffing) applied to the label after the label was initially adhered to a container, bag, box, and/or object. Upon activation, visible color or a printed warning indicia is visible on a front surface of the label, providing evidence that the label was removed after initial application or providing evidence that the label was attempted to be removed after initial application.

Disclosed are a label film including a hidden pattern that is displayable through scraping a surface thereof and a manufacturing method thereof. A concealment scraping layer printing ink is formed by mixing, in respect of volume ratio, 1-10% nitrocellulose, 5-15% polyamide resin, 20-30% silver paste, 5-15% pearl powder, 10-20% ethyl acetate, 20-30% toluene, and 5-15% isopropyl alcohol and applied with intaglio printing such that a displayable mark formed of a traditional printing ink and including at least one pattern, character, or mark and at least one concealment scraping layer pattern formed with the concealment scraping layer printing ink are combined together and collectively formed on and attached to at least one surface of a single-layer label film substrate, with the concealment scraping layer pattern set on and covering at least one displayable mark, followed by steps of slitting, bonding, and cutting, to form a label film having at least one concealment scraping layer pattern covering and concealing at least one displayable mark through a combined printing operation.

A combined primary label and secondary label comprises a first piece of paper, a first release coating disposed on a portion of the first piece of paper, a second piece of paper, a second release coating different from the first release coating and disposed on a portion of the second piece of paper. The combined primary and secondary label further comprises an adhesive layer disposed between the first and second pieces of paper such that (i) a primary label can be peeled away with at least some adhesive of the adhesive layer from the second release coating disposed on the portion of the second piece of paper, and (ii) a secondary label can be peeled away with at least some adhesive of the same adhesive layer from the first release coating disposed on the portion of the first piece of paper.

A 3-D label is disclosed including moving patterns using fine patterns and microlenses, including a lens layer in which a pattern display unit having microlenses that are convex in a semicircumferential form arranged at specific intervals and to represent patterns formed in a pattern layer regardless of a visual field focal length and a secret unit placed on one side of the pattern display unit and displaying intended patterns formed in the pattern layer when a predetermined visual field focal length is reached are integrated and formed; and the pattern layer disposed under the lens layer and having patterns formed thereon so that the distance between the central point of each of the microlenses and the central point of an adjacent microlens is matched with the distance between the central point of each of pattern cells and the central point of an adjacent pattern cell in the state.
