Abstract: The present disclosure provides a chemical supply system, including a chamber, a tubing extending into the chamber, an interlock apparatus, including a fixture for fastening the tubing, and means for determining whether the tubing is fastened by the fixture.

Abstract: A squeezable hollow thin walled dispensing container having an open ended main body is provided with a closure plug insertable into the open end, the plug having outwardly projecting ribs engaging the inside of the peripheral wall of the body, a locking member is received exterior of the body around the plug, and the plug and locking member entrapping portions of the wall therebetween to sealingly close the open end.

Abstract: A wind collection apparatus includes an outer tube and an inner tube assembly. The outer tube has a front end and a rear end. The inner tube assembly is installed in the outer tube and has an inner channel and an outer channel. An air-guiding channel is formed between an outer circumferential wall of the inner tube assembly and an inner circumferential wall of the outer tube. The inner channel has two openings. One of the openings is located at the front end and the other one of the openings is located at the rear end. The outer channel is in communication with the inner channel and the air-guiding channel at two ends of the outer channel.

Abstract: A safe device for a squeezable container includes a protective cover, a body, and a bottom cap. The protective cover includes an idle cap, an inner cap, and a mouthpiece. The idle cap is rotatably mounted around the inner cap. The body includes a compartment for receiving a squeezable container. A plurality of non-return blocks are formed on an outer periphery defining an upper opening of the body and meshable with non-return blocks on the mouthpiece to prevent the mouthpiece from disengaging from the container. The bottom cap is engaged in and seals a lower opening of the body. A rotational force applied to the idle cap can only be transmitted to the inner cap when a force greater than a predetermined magnitude is applied to move the idle cap downward to tightly engage with the outer periphery of the inner cap.

Abstract: A crimp tube having a sealed throat opening at one end and an open end crimped close at an opposite end is provided with an internal stiffener which is resilient and will return to its original shape upon release of pressure. The stiffener is generally cylindrical and has generally radial openings therethrough communicating to the space between the outer diameter of the stiffener and the inner diameter of the tube to allow contents to flow to the interior of the stiffener and from the interior of the stiffener to the area between the stiffener and the inner diameter of the tube. The tube being formed of soft material is collapsible against the stiffener and further collapsible with the stiffener to dispense materials from the tube subsequent to opening the closure at the throat. On release of pressure the stiffener will return to its uncompressed condition.

Abstract: A bottle for flowable adhesive includes an outer tube made of soft metal and an inner tube made from a material that allows the inner tube to restore its original shape when an external squeezing force applied to the outer tube is released. The inner tube has an outer diameter the same as an inner diameter of the outer tube, with an outer peripheral face of the inner tube being in intimate contact with an inner peripheral face of the outer tube. When the outer tube is squeezed, the flowable adhesive contained in the inner tube is dispensed through the spout of the dispensing member. The outer tube restores its original shape when the external squeezing force applied to the outer tube is released, as the inner tube pushes the outer tube outwardly when the inner tube is restoring its original shape.
