These easy-squeeze wash bottles feature an integrated tube used to dispense liquid without the need to tilt the bottle. The wide base provides stability when filling. In addition to the screw cap, a plastic plug insert comes with each bottle, providing additional leak-resistance. Simply insert the plug into the mouth of the bottle prior to closing the lid. This ensures a leak-resistant seal and makes these bottles ideal for long-term storage. The cap and bottle neck have molded-in tagging points which are designed for securing the cap to the bottle using wire security ties. This makes the bottle tamper-evident. The bottle is approved for use with food products.  These bottles are easy to clean, extremely durable and chemical resistant.
