Abstract
A reclosable box constructed from a flat blank which is cut and folded is featured by a number of different locking devices which may be used alone or in combination. The box can be constructed from a single flat blank and is easily mass produced, and is suited for automated assembly and filling operations. The reclosable portion of the box does not interfere with filling of the box in production. In addition to providing locking devices to keep the box closed until intentionally reopened, devices are disclosed which hold the reclosable portion of the box in an open position to dispense contents of the box. The mouth of the box can be configured to allow redimensioning of the mouth by the user so that selected contents can be dispensed in chosen measured portions.
