Abstract:
1. An elongated display device and an elongated delivery tunnel for an aerosol container, the elongated display device and the elongated delivery tunnel extending adjacent and parallel to one another, the elongated display device displaying the amount of product remaining in the aerosol container, one end portion of the elongated delivery tunnel having an input passage adapted to be installed on the top portion of the actuator tube of an aerosol container substantially at a right angle to the length of the actuator tube, the lower portion of the actuator tube, when depressed into the aerosol container, releasing a valve within the aerosol container for enabling the flow of the product through the valve, through the lower portion of the actuator tube, into the top portion of the actuator tube, and into the input passage of the elongated delivery tunnel adapted to be installed thereon, the elongated delivery tunnel having an elastic passage with one end thereof connected to the input passage of the elongated delivery tunnel, and an output passage portion connected to the other end portion of the elastic passage and leading to a discharge opening, the elongated display device being disposed in transparent material extending adjacent to the elastic passage and the output passage of the elongated delivery tunnel, the elongated display device having an elastic passage portion adjacent to the elastic passage of the elongated delivery tunnel and a downstream passage portion extending adjacent to the output passage portion of the elongated delivery tunnel, gel indicating material being disposed within the elastic passage of the delivery tunnel and the downstream passage portion of the elongated display device being disposed in transparent material extending adjacent to the elastic passage and the output passage portion of the elongated delivery tunnel, an increasing pressure and resulting expansion of the elastic passage of the elongated delivery tunnel on the elastic passage portion of the elongated display device as the product is released from the aerosol container, causing the gel indicating material disposed within the elastic passage portion of the elongated display device to advance progressively into the downstream passage portion of the elastic passage portion, with a resulting contraction of the elastic passage portion of the elongated display device, thereby displaying the amount of product remaining in the aerosol container.
