Abstract
A blister pack may include a containing body with an opening; and a lid sealed over the opening and provided with a weakening pattern, wherein a width of the lid at the weakening pattern is thinner that a width of the lid elsewhere, and wherein the lid is configured to burst at the weakening pattern when the blister pack is subjected to pressure, so as to allow liquid content inside the containing body to be discharged out of the blister pack through the burst weakening pattern. A blister pack holder is also disclosed.
Core Innovation
The invention relates to a blister pack comprising a containing body with an opening and a lid sealed over the opening, where the lid includes a weakening pattern. A width of the lid at the weakening pattern is thinner than a width of the lid elsewhere, so that the lid is configured to burst at the weakening pattern when the blister pack is subjected to pressure. This bursting allows liquid content inside the containing body to be discharged out of the blister pack through the burst weakening pattern.
The weakening pattern is localized and forms a burst weakening region in the lid. Embodiments include lid weakening geometries such as lines, cross, Y, two-part, and continuous forms, and manufacturing approaches that create controlled weakening at the lid. The blister pack also includes a sleeve accommodating the containing body, and the sleeve geometry is described as cooperating with the containing body to expel the contents.
The invention also describes a blister pack holder system for dispensing the contents from multiple blister packs. The holder comprises a block with one or a plurality of bores extending through the block, where each bore is configured to accommodate a blister pack, and pressure applicators apply pressure to cause bursting of the lid and dispensing of liquid from the blister pack through an opening of the bore. Each bore has a cylindrical form and includes a supporting flange at a second opening for supporting the blister pack, with embodiments describing brim support and structural features such as voids.
Claims Coverage
The document provides two independent claim sets, covering a pressure-burst blister pack and a blister pack holder that applies pressure and dispenses burst contents from blister packs into bore openings. Across these independent claims, the inventive features focus on localized lid weakening that bursts under pressure to discharge liquid and a holder architecture that couples multiple blister packs to pressure applicators and bore outlets with a supporting flange.
Localized lid weakening to burst and discharge liquid
A blister pack including a containing body with an opening and a lid sealed over the opening with a weakening pattern, where a width of the lid at the weakening pattern is thinner than a width of the lid elsewhere, and where the lid is configured to burst at the weakening pattern when the blister pack is subjected to pressure to allow liquid content inside the containing body to be discharged out through the burst weakening pattern.
Sleeve accommodating the containing body
The blister pack further comprising a sleeve accommodating the containing body.
Bores-through block with pressure applicators to burst lids and dispense through bore openings
A blister pack holder comprising a block with one or a plurality of bores extending through the block, each bore configured to accommodate a blister pack with a containing body and a lid sealed over the opening, and one of a plurality of pressure applicators applying pressure when actuated on the blister pack to cause bursting of the lid and dispensing of liquid from the blister pack through an opening of that bore.
Cylindrical bores with supporting flange at a bore end
Wherein each bore has a cylindrical form, each bore comprises a first opening at a first end and a second opening at a second end opposite the first end, and the second opening comprises a supporting flange for supporting that blister pack.
Overall, the claim coverage centers on a blister pack whose sealed lid includes a localized weakening pattern that bursts under applied pressure to discharge liquid through the weakened region, and a holder with bores, pressure applicators, cylindrical bore geometry, and a supporting flange that supports the blister pack while enabling dispensing through the bore openings.
Stated Advantages
Allows liquid content inside the containing body to be discharged out of the blister pack through the burst weakening pattern when subjected to pressure.
Enables dispensing of liquid from the blister pack through an opening of a bore when pressure is applied by pressure applicators in the blister pack holder.
Provides support for the blister pack via a supporting flange at a second bore opening.
Documented Applications
Parallel testing of samples using analysis chips and diagnosis chips, where dispensed reagent contents are provided to outlets for processing by a processor.
