NATURAL FIBER BASED LID WITH UNDERCUT
20230151555 · 2023-05-18 ·

The disclosed embodiments relate to a manufacturing component as a first tool in a forming station at least for endforming a preformed lid made from a material to form an undercut comprising natural fibres. The preformed lid includes a top part and a side part circumferencing the top part, where the manufacturing component is adapted to contact an outer side of the preformed lid to endform the preformed lid by exerting a first movement in axial direction along a center axis of the manufacturing component and a later second movement in a second direction towards the side part of the preformed lid. Multiple side forming elements of the manufacturing component are arranged to exert the second movement by applying an outer pressure onto an outer side of the side part to form an undercut into the side part.

DISPENSING CAPSULE AND METHOD AND APPARATUS OF FORMING SAME
20230365322 · 2023-11-16 · ·

In one example, a process for manufacture of a pulp-based dispensing capsule is disclosed. The process includes providing one or more mesh tool sets that are each contoured to one or more preform shapes of the dispensing capsule. Note that each preform shape is a partially shaped version of a final form shape of the pulp-based dispensing capsule. The process also includes providing a holding tank containing a suspension that includes water and pulp fibres; and arranging the mesh tool sets to allow immersion into and withdrawal of the mesh tool sets from the suspension. The process also includes applying a vacuum to the mesh tool sets so as to draw pulp fibres from the suspension onto the mesh tool sets while immersed in the suspension to form a preform pulp fibre mat; and in a second toolset, deforming each preform shape in the preform pulp fibre mat towards the final form shape by the application of pressure.
