摘要： A device is provided for testing the integrity of each container in a conveyed sequence of containers by individually applying pressure internally of each, sensing that pressure and generating a signal having a magnitude corresponding to the value of that pressure, comparing that signal magnitude to a selected threshold signal value, providing an output control signal indicative of the achievement of that signal magnitude and setting an enablement device in one of two states corresponding to the presence and absence, respectively, of that output control signal. One of those states corresponds to an unacceptable container condition and the other to an acceptable container condition. If the unacceptable container condition or reject state exists, a reject cycle is enabled over at least an enabling duration sufficient to clear the container or broken portion thereof from the position it occupies in the sequence. The reject apparatus enabled during the reject cycle is constrained to apply a reject force such as a jet of air over the space occupied by the unacceptable container as well as space upstream therefrom within the extent of the reject cycle to clear from the conveyor all debris associated with the unacceptable container. A counter is provided in several embodiments for determining the number of acceptable containers in a give sequence. A mechanical reject device extends and retracts within the selected enabling duration while the air is enabled for the duration of the reject cycle to purge the conveyor surface.

摘要： A combined relief valve and lid structure is provided for pre-mix beverage and syrup containers having a tubular body enclosing a relief port in the lid, an annular valve seat surface about the relief port and raised higher than the lid surface and drain ports extending from the valve seat surface down to the lid surface to enhance drainage of the entire internal portion of the valve body. The relief port is closed by a spring biased poppet and has a biasing spring held in place in the top of the tubular body by a one-way detent and retainer clip arrangement which must be destroyed to remove it from the valve body to gain access to the relief valve poppet. The valve cannot be tampered with unless this retainer clip for the valve spring is destroyed. The retainer clip is ported to permit cleaning steam or other fluid to enter the top of the valve and drain off through the drain ports without accumulation of condensate or residual fluid in the valve. The poppet is basically cylindrical with relieved vertical side portions or flats to enhance drainage and exposure of the valve surface for cleaning.
