The method of continuously manufacturing pencils or crayons consists in coextruding a filled first thermoplastic material referred to as "lead" material, and around it both an intermediate "protective" layer of a thermoplastic material having no expanding agent and a second thermoplastic material containing an expanding agent and referred to as "wood" material, and in cooling said coextruded thermoplastic materials. According to the invention, the thermoplastic material constituting the protective layer is determined so that during cooling it remains deformable while the lead material shrinks. The pencil is constituted by superposing a core of a filled first thermoplastic material referred to as "lead" material, a protective layer of a non-expanded thermoplastic material, and a layer of an expanded second thermoplastic material referred to as "wood" material. According to the invention, the thermoplastic material constituting the protective layer has a solidification point which is lower than that of the thermoplastic material constituting the lead material.

A secure communication system comprises at least one virtual private network (VPN) gateway for managing tunnel information of other VPN gateways that are connected via tunnels for secure communication, and for transmitting the tunnel information to each terminal connected via a secure network. When a packet received from the terminal is destined for the secure network, the VPN gateway encrypts the packet, adds a tunnel header to the packet, and transmits the resultant packet to the corresponding tunnel. At least one terminal stores the tunnel information received from the gateways. When tunnel information identical to the destination address information of the generated packet is not stored, the terminal fragments the packet into a first set packet fragmentation size, and when tunnel information identical to the destination address information of the generated packet is stored, the terminal fragments the packet into a second packet fragmentation size, and transmits the fragmented packets to the VPN gateway connected to a corresponding secure network. The packet fragmentation size can be adjusted when the packet is changed in size according to the type of network, thereby preventing the number of packets on the network from increasing geometrically.

The present invention is a mechanically operating device used for packaging and applying a product. A molded product traverses through a barrel as an actuator sleeve is rotated. The actuator sleeve rotates an actuator, propelling a driver through the barrel. The driver is keyed into the barrel using a clutch washer—the clutch washer prevents the rotation of the driver. Mechanical actuating splines on the actuator engage the threads of the driver. The forward motion of the driver transversely pushes a cup out from an orifice of the barrel. The molded product is fitted within the cup. A cap is hermetically sealed to a barrel to create dynamic vapor chamber that prevents any contamination or alteration of the molded product. Primary and secondary seals between the barrel and the cap as well as between the cup and the barrel maintain the airtight feature of the dynamic vapor chamber.
