Abstract: The present bag-in-a-box package is of a three unit structure, having a top unit, a body unit and a bottom unit. The box has a pair of handles for ease in handling the box and a tear strip structure for opening the box. In a preferred mode the tear strip has a grip that is adjacent one of the handle apertures. The tear strip can be of any known structure such as a series of perforations or serrations, or a separate film, string or filament applied to the top panel. This makes the tear strip easier to grip and the box easier to open. The bag part of the structure will preserve the freshness of the contained product while the box will provide structural integrity and a means for easily handling the box.

Abstract: The reclosable bag has a gusset side structure so that the bag can be self-supporting on its bottom surface. The reclosable structure can be an internal structure or an external structure. As an external structure the front and rear walls extend above the reclosable seal and are bonded together above the reclosable seal. This extended wall structure is removed to remove these tamper evident seal. If within the bag the tamper evident seal is composed of a loop of film extending downward from each side of the reclosable seal to seal the contents of the bag. This loop must be broken to open the bag. The preferred reclosable seal is a zipper with bonded stays or each end to maintain the zipper on the bag. The bag has diagonal seals at the lower corners for forming a flat bottom to the bag and at the upper corners to provide vents for pressure equalization. The bags are made by a process where all processing is on line except for forming the zipper which is constructed off-line.

Abstract: The dispenser is for dispensing viscous products, has an ergonomic shape, and an automatic closure. The closure opens promptly upon initiation of an actuator and before the flow of viscous product from the dispenser. Further, the closure closes the dispenser outlet at the end of the return of the actuator to its rest position. Further, an outlet valve from a pump chamber remains open as an inlet valve to the pump chamber opens. This causes a suckback of viscous product near the dispenser outlet to flow into the dispenser. The automatic closure does not close as dispenser outlet until the suckback of viscous product has occurred. The automatic closure also functions as a knife or blade to assist in cutting the viscous product to maintain cleanliness and hygiene of the package.

Abstract: A closure for a multi-chamber container can have a flow director device that will assist in the dispensing of the products from the multi-chamber tube in a number of product streams that are greater than the number of chambers in the container. This provides versatility in the dispensing of products from such tubes. By the use of several different closures with different flow patterns different products can be delivered in a number of patterns form the same container.
