Abstract
Description
[0001] The invention relates to a slipcase designed as an Advent calendar for one or more books, in particular from a publisher's catalog. The slipcase serves both for the presentation and interactive use of the contained book during the Advent season. State of the art
[0002] Slipcases are common in publishing and generally serve to store a book decoratively or protectively. Advent calendars, on the other hand, usually contain physical items (e.g., sweets, small gifts) or visual surprises (e.g., illustrations, sayings). A combination of both principles—the integration of a book slipcase with the function of an Advent calendar that references passages within a book—is unprecedented. Object of the invention
[0003] The invention is based on the objective of creating a novel product that presents a book in an appealing way during the Advent season while simultaneously enabling interactive access to the book's content. The book and Advent calendar should form a functional, design-related, and content-related unit that awakens curiosity about the book's content, promotes reading motivation, and offers an additional purchase incentive during the early Christmas season. Solution to the task
[0004] This problem is solved by the features of claim 1.
[0005] The slipcase according to the invention consists of cardboard, card stock, or paper and is preferably rectangular in shape. On one outer side of the slipcase—preferably the front—24 doors are arranged, which are perforated and provided with small tabs for opening. The doors are all the same size and can optionally be arranged linearly, randomly, or in the classic Advent calendar style across the surface.
[0006] Behind each door is a number and text field with a printed number combination. This combination refers to a passage in the book inside and follows the logic of page / line / word. The number combination is printed on the inside of the door and is only visible after it has been opened.
[0007] In addition, behind each door is a question or a short clue that can be answered by referring to the indicated passage. These questions are open-ended, clever, witty, or philosophical, depending on the type of book, and encourage the reader to open the book to the corresponding passage and explore it further.
[0008] The slipcase holds the book loosely, but can be designed to stand or lie stably even without a book. It can be used for individual books as well as book sets and is suitable for all book formats (hardcover, paperback, children's or young adult books).
[0009] The design of the slipcase can be either coordinated with the book cover or executed independently. All common printing techniques are possible as finishing options, in particular hot foil stamping, varnishing, or spot printing.
[0010] Optional enhancements can include graphic elements, QR codes, digital content, or audio / video links that provide additional information or multimedia experiences related to the selected book passages. Advantages of the invention
[0011] The advent calendar slipcase according to the invention creates a novel combination that is convincing both in terms of design and function. The reader experiences the book anew in 24 stages throughout December. The publisher gains an innovative marketing tool for promoting existing titles or new releases.
[0012] The Advent calendar slipcase combines a collectible, a gift item, and a reading game into a product with high emotional and aesthetic value.
