Title: Pin-lined cylinder and transfer mixing section in single extruder - has throttling pins in housing channel area with max. vol. and increased output with reduced torque
Inventor: CAPELLE GERD
IPC: B29C48/67
Filed: 1991-05-04
Abstract: A pin transfer extruder combines a pin-lined barrel and transfer mixing section in a single unit.

Abstract: In a sales package for rigid haberdashery articles (34), a container (14, 30) is used which is provided with a transparent container part (30, 30') made of plastic and is attached to a cardboard sheet (10, 10'). The cardboard sheet (10, 10') serves for hanging the sales package on a rod of a self-service device. For dividing the sales package in a simpler manner which is more favourable in terms of material, it is proposed to construct the container (14, 30) from a three-dimensional folding blank (11, 11') of the cardboard sheet (10, 10') itself, specifically as a lower tray (14, 14') which continues in a flat, integral cardboard end piece (12, 12') which serves for hanging up the sales package. The sides (16, 16') of the lower tray project beyond the vertical plane of the cardboard end piece (12, 12') which is effective for hanging up and form the insertable male part of a two-part insertion coupling. The female part of the insertion coupling which is effective as receiver is formed by a cap (30, 30') whose sides (32, 32') grip around the sides (16, 16') of the tray when coupled.
