[0019]Another embodiment includes a dispenser adapted to receive a flexible bag and dispense a product contained in the flexible bag, the dispenser including a housing having a first wall and a second wall movably connected to the first wall and defining a chamber having a first end and a second end; a tacky portion contacting the housing enabling the flexible bag to firmly adhere to a first portion of the tacky portion and loosely adhere to a second portion of the tacky portion; a handle located proximate the chamber first end and having a reversely biasing actuating device; a segmented piston positioned in the chamber and actionably coupled to at least the actuating device enabling the segmented piston to advance in a reversible manner, applying pressure to the flexible bag and dispense the product; and an end cap adapted to be removably received by the housing proximate the second end, the end cap defining at least one outlet adapted to allow flow in only one direction, wherein the handle and segmented piston act in concert, such that upon applying pressure to the flexible bag, everting the flexible bag and dispensing a predetermined amount of the product, and upon completion of dispensing a predetermined amount of the product, relieves any residual pressure on the flexible bag, preventing the product from weeping. The at least one outlet has a valve fitment that allows product to flow there through in only one direction and/or includes the outlet having a predetermined shape allowing product to flow there though in only one direction. The tacky portion is mounted to at least one of the first wall an

Problems solved by technology

While tin cans offer good shelf life performance, tin cans contribute to waste of product that clings to the side of cans.

Further, tin cans are heavy to ship, store, and are heavy and voluminous for disposal.

Additionally, tin cans require can openers to open—retrieving the opener reduces operational speed, and the opener may be difficult to locate, further reducing efficiency.

Opening tin cans may also result in sharp edges that may tear garbage bags and pose a laceration risk.

However, gallon jugs contribute to waste in the same fashion as tin cans, and share many of the negative attributes of tin cans.

Caulk cartridge type cans leave less product in the canister, but require priming of each can and may also generate significant wasted product.

For example, a 25-ounce cartridge delivering a one-ounce payload may waste 4% of the product due to priming.

However, caulk cartridge type cans may not be hermetically sealed, may be more expensive and may take up more room in a landfill.

Devices that use gravity actuated rollers or gears are complicated to manufacture and may involve manipulating the rollers in non-intuitive ways.

Other devices that utilize more complex means for releasing condiment from the bags require that the b
