US Patent 8524300: Covered Retracted Confectionery
- Title: Covered retracted confectionery
- Assignee: Imaginings 3 Inc
- Inventors: Sidney Diamond, David Lisowski
- Filing Date: May 3, 2012
- Issue Date: September 3, 2013
- Abstract: The patent describes a covered, retractable confectionery device. It features a housing with hinged covers at the top that move between closed and open positions. A shaft inside the housing carries a confectionery and can move between a retracted (covered) and extended (exposed) position. A flange near the top of the shaft engages tabs on the hinged covers to keep them closed when the shaft is retracted. An actuator, slideably mounted on the exterior of the housing, allows the user to manually move the shaft to the extended position, exposing the confectionery. A bias (e.g., a spring) automatically retracts the shaft and confectionery, and closes the covers, when the actuator is released.
Plain-Language Overview of Independent Claims:
Claim 1: This claim outlines a confectionery device where a candy on a shaft is housed within a casing. Hinged covers at the top protect the candy. When the shaft is in its lowered (retracted) position, a part of the shaft (a flange) keeps the covers closed. An external slider (actuator) pushes the shaft and candy upwards to expose the candy. When the slider is let go, a biasing mechanism (like a spring) automatically pulls the shaft and candy back down, closing the covers. This biasing mechanism becomes stronger when the actuator is used to extend the shaft.
Claim 8: This claim is similar to Claim 1 but specifies that the biasing mechanism is a spring. It further details that this spring is pushed into compression when the actuator is moved to extend the shaft, thereby storing energy to retract the candy and close the covers automatically.
Claim 12: This claim is also similar to Claim 1 but specifies that the biasing mechanism is a spring. However, it distinguishes itself by stating that the spring is pulled into compression (i.e., stretched) when the actuator is moved to extend the shaft. This stretched spring then automatically retracts the candy and closes the covers upon release of the actuator.
Uncertainty Regarding CAFC 2026 Dockets:
A search for US patent 8524300 within CAFC 2026 dockets could not be definitively confirmed. While the U.S. Court of Appeals for the Federal Circuit provides scheduled case calendars in PDF format for April, May, and June 2026, the available search capabilities do not allow for direct querying of specific patent numbers within these documents at this time.
