摘要:
The invention provides a method of co-injection molding. The method includes mixing a plastic inner material and an endothermic-blowing agent to form a core mixture. A plastic outer material is injected from a first injection unit into a co-injection manifold to create a flow of outer material therethrough. The core mixture is injected from a second injection unit into the co-injection manifold to create a flow of core mixture therethrough. The flow of the outer material and the flow of the core mixture are then controlled through the co-injection manifold and into a mold cavity. The core mixture expands as heat is provided for the endothermic-blowing agent to absorb.

摘要:
A co-injection nozzle pin (20) having downstream and upstream ends. The nozzle pin has therein a central bore (30) including an upstream end (32) adapted to communicate with a first material and a downstream end (34) exiting at the downstream end of the pin. The nozzle pin also has an outer surface (36) including a first portion (38) having a diameter D1, a second portion (40) having a diameter D2, wherein D2 is less than D1 and the first portion is rearward of the second portion. The pin further includes a channel (46) spiralling around the outer surface and being adapted to communicate with a second material. The channel (46) includes a first segment (52) defined in the first portion (38) of the outer surface and increasing in depth as it travels in a downstream direction and a second segment (54) defined in the second portion (40) of the outer surface and decreasing in depth as it travels in a downstream direction.
摘要:
A display device that can be used singularly for securing a single open-faced container on a shelf for display of and access to the container contents or in multiples to secure any number of like open-faced containers on a shelf for display of and access to the contents of each container. The display device includes a frame defining an access opening. The frame is dimensioned to surround the open face of the container on which the frame is to be mounted. The display device further includes a releasable lock for removably securing the frame to the open-faced container, and an anchor for attaching the frame to the shelf when the display is in use.
摘要:
A rain gutter assembly including an elongated trough-like rain gutter having a rear wall, a trough and a leaf guard integrally connected by a pair of living hinges, grommets adapted to house a fastener for supporting the rain gutter, and a connector for sealingly connecting a pair of closely-spaced, aligned rain gutters.
摘要:
A U-shaped raceway having bottom and side walls formed as substantially rigid plastic panels, and flexible plastic hinges integrally joined between the lower edges of the side walls and the adjacent edges of the bottom wall. The plastic hinges are soft and flexible, and of substantially less hardness than the walls. The plastic hinges extend across the thickness of the walls. The raceway is formed as a dual extrusion so that the hinges are integrally joined to the rigid walls. During the extruding step, a rigid bridge structure is also extruded so as to span transversely across the hinge outwardly from one of the surfaces of the panels to maintain dimensional stability across the hinge. The bridge structure is severed from the panels following the extrusion operation.

An improved surgical suction probe includes a tubular probe portion and a tubular handle portion joined together to define an internal bore. A reciprocable one-piece valve is disposed within the bore and is movable between flow and non-flow positions for regulating flow of material through the probe. The components of the probe may be easily and inexpensively fabricated from plastic or other suitable material, thus providing a suitable suction probe arrangement with the necessary operational characteristics which may be fabricated inexpensively for single use service.
