Abstract
A trigger spray container that prevents dry firing and solves the problem of interupted spray as the containers contents are dispensed and reduced to a level that allows the end of straw tip of trigger spray apparatus to become disengaged with liquid as the container is tilted towards the users target. As the user inverts or rotates the container from a vertical position, downwardly, towards a horizontal plain and aims the spray tip output nozzel towards the intended target, the liquid level adjusts within the container. Therefore, it becomes advantageous for end of straw tip to be positioned at the lowest point on container base, side of container base nearest target. This is achieved by forming an integral straw guide molded into the container body that provides a passage way or tube for the straw to be guided through, thereby directing the straw tip to this position. The straw length of the trigger spray apparatus is of sufficient length such that it travels through integral straw guide and engages with intended base corner as trigger spray apparatus becomes securably attached to the mouth opening of container. The liquid contents of the container can now be fully consumed, with…
