The surface port device has a tube with a throughbore between its inlet and outlet ends, and an enlarged flat base at the outlet end, suited to be bonded by adhesive securely to a structure surface with the tube bore aligned over a surface crack. The inlet tube end is stepped, having several adjacent generally cylindrical axially extended land areas of progressively smaller diameters I.D. in moving downstream toward the outlet end. The land areas are sized both in diameter and axial length to correspond to certain more common generally cylindrical land areas of conventional available material mixing/dispensing tubes proximate the outlet nozzles thereof. This allows the establishment of a mechanically sound leakproof separable joint between the material dispensing tube end the surface port device. A captive check ball in the tube bore automatically can be shifted between opening the port bore or closing it to preclude material backflow. A cap can cooperate snuggly with the port bore land area for mechanically positive bore port closure, while further unseating the ball check to bleed the port bore beforehand.
The invention teaches a kit-like system and apparatus for dispensing a multiple component reactive material from two cartridges each having an exteriorly threaded semi-cylindrical outlet nozzle, where the respective components need not be mixed together immediately, but only in close proximity of the intended use of the material. Thus, the cartridge nozzles will be spaced from one another, and at least one will be paired up with a dummy nozzle having a like exteriorly threaded semi-cylindrical nozzle, but with no outlet. Special universal fittings are provided in the kit that fit over the paired cartridge and dummy nozzles, and over a separate conventional mixer, and further that allow for hoses to be connected thereto, to define separate component flow paths from the separate cartridges to the remotely located mixer and then to the intended discharge location. A clamp on the common discharge flow path can be used for regulating the material discharged from the component cartridges proximate the end use location.
The disclosed port device has a tube with a base that can be permanently bonded to a surface with its outlet throughbore aligned with a crack therein, for funneling the material into the crack; and the port device tube can have a low silhouette of possibly 3/8" high overall, suited for leaving the device in place after crack filling had been completed. The material under pressure can be communicated to the port device via a flexible hose connected between special fittings, that respectively can be seated across leakproof joints established with the material dispensing system and with the port device. This means that the material dispensing system can be well spaced physically from the crack itself, by almost the hose length, and that the operator need not hold the material dispensing system relative to the crack. A clamp on the hose between the fittings, can operate when closed to preclude or restrict material flow therepast, allowing upon user manipulation of the clamp the control of the material flow into the crack from locations spaced from the dispensing system.
The disclosed port device has a tubular inlet end stepped with progressively smaller land areas sized to establish a leakproof separable joint with outer land areas of conventional material mixing/dispensing tubes. Separate radial base blades hinged from the port device near its outlet end fit either unfolded flush against a flat surface aligned over a crack therein or back-folded into the crack itself, for alternative uses of the port device. The port device beyond the base is beveled across end edges, for cooperating with corner surfaces and guiding material discharge under pressure into an underlying corner crack, where two partly folded base blades can then fit flush against the corner surfaces. An expandable sleeve fitted into the structure crack can be deformed radially upon tightening a nut for retaining the port device in the structure even when dispensing material under high pressures into the crack, as by an accessory fitting mechanically locked to the port device. Another accessory fitting having interior and exterior stepped land areas sized the same as the material tubes and port device land areas, and the inner bore and exterior surfaces of conventional flexible hoses, provide for the remote interconnection of the material tube and port device via such hoses of virtually any length.
An improved non-spill water bottle cap is developed for preventing water spillage when a water bottle is inverted to place on a water dispenser. The improved non-spill water bottle cap comprises a cylindrical plastic tube (10), a spherical float (20) for controlling the water flow, a plastic cap head (30) integrally formed with the cylindrical plastic tube (10), an edge frame (11) disposed at the end of the cylindrical plastic tube (10) and an annular flange (13) with a plurality of peepholes (13a) disposed at the mouth of the plastic cap head (30) for retaining the spherical float (20) inside the cylindrical plastic tube (10), and an annular sealing ridge (12) for momentarily blocking the water flow path by contacting the spherical float (20) to form a seal when the water bottle is inverted.
A method of separately storing, mixing, combining and dispensing reactive two component materials by employing the use of a rotary stop cock that is formed so that in a first selected position it can separate a plurality of compartments, in a second selected position can allow for the flow of material from one or more upstream compartments into a downstream compartment, while also allowing air to vent from the downstream compartment through the stop cock and out to the atmosphere, and in another selected position can allow for the flow of material from what was the downstream compartment to what was the one or more upstream components without venting any of the compartments.
