A bag includes: a bag body at least having a first surface and a second surface facing each other with a storing space formed between the first surface and the second surface; and a tape member provided between the first surface and the second surface and defining one side of the storing space. The tape member includes, in a cross section, a first portion formed of a first resin composition and a second portion formed of a second resin composition different from the first resin composition. The first portion is bonded to both the first surface and the second surface at a first section of a longitudinal direction of the tape member while bonded to only the second surface at a second section of the longitudinal direction, and the second portion is bonded to the first surface at the second section.

Disclosed is a child-resistant bag with an interlocking seal, wherein the seal is comprised of corresponding pods with interlocking hooks. The pods and interlocking hooks are attached and configured in manner that requires specific manipulation of the seal to open, which provides a child-resistant seal.

Described herein is an airtight storage bag mouth assembly defined by opposing first and second elongate panel members. This inventive concept is equipped with adhesive flaps, a slider assembly, and may have a writing label. Unitable coupling members disposed on the opposing first and second elongate panel members are longitudinally disposed substantially along the length of the panel members. A slider assembly is configured to press inward on the unitable coupling members wherein at least one protrusion member disposed on a first unitable coupling member is contiguously and removably disposed within at least one groove member disposed within a second unitable coupling member. The polymer container mouth assembly allows the bag to be in an open or closed state.

A bag body includes a bag main body and a zipper tape heat-sealed to an inner surface of the bag main body. The zipper tape comprises a pair of belt-shaped bases and two pairs of mating portions configured to be mated with each other. One of the belt-shaped bases is attached to the bag main body only at a widthwise side near an opening. First one of the mating portions includes a pair of hooks provided to each of the belt-shaped bases and respectively having nails at ends of the hooks that are configured to be meshed with each other. The second mating portion includes a concave female mating portion provided to the belt-shaped base and a male mating portion having the same shape as the hook and configured to disengageably mate with the female mating portion. The nail of the hook protrudes toward the opening.

A female belt-shaped base is attached to a bag body at a region from a female hook to a first end near an open end of the bag body and to a second end near a housing space. A male belt-shaped base is attached to the bag body only in a bonding region without being attached at a region from a position where an engagement portion is continuously attached to a first end near the open end of the bag body.

The fitting tool (10) includes a first fitting member (12) that includes a first fitting part (18) provided on a strip-shaped first base material (16) in a longitudinal direction of the first fitting member, and a second fitting member (14) that includes a second fitting part (22) provided on a strip-shaped second base material (20) in a longitudinal direction of the second fitting member and is detachably fitted to the first fitting part, the first base material and the second base material each includes an extension part (13, 17) that extends from a first end part (16c, 20c) in a width direction of the first base material and the second base material to an outer surface side opposite to a facing surface (16a, 20a), on which the first fitting part or the second fitting part is provided, the extension part facing to the outer surface (16d, 20d), and a second end part on a side opposite to the first end part is separately arranged from the extension part.

Embodiments include a method of manufacturing a container with a leak resistant seal. The method includes forming an elastomer or a plastic or any combination thereof into a container inside out by forming an outside portion of the container on an internal surface of the container before inverting the container and forming an inside portion of the container on an external surface of the container before inverting the container. In embodiments, the method includes forming or coupling a leak resistant seal on the external surface of the container before inverting the container. The leak resistant seal provides access to the inside portion of the container when the leak resistant seal is open after inverting the container and holds at least liquid internal to the container when applying an external force to the container without use of an external structure to keep the leak resistant seal closed after inverting the container.

The invention provides a bag container with a sealing mechanism including first and second container housings to define an open top. The sealing mechanism includes female and male engagement members respectively positioned on the two container housings. The male engagement member includes a body portion and at least a pair of protrusions extending from opposite sides of the body portion and facing away from each other, the protrusions each having opposite first and second side surfaces, and the second side surface extending at an acute angle relative to an orthogonal direction of the longitudinal axis of the male engagement member. The female and male engagement members are sized and shaped for mating engagement to hermetically seal the open top. The invention also provides a sealing mechanism comprising female and male engagement members having mating wavy cross-sectional profiles in a plane parallel to the respective container housings.

A bag packaging closure and dispensing device is disclosed. The device has first and second legs secured together about a package. The legs include first and second flexible portions biased apart to provide a space therebetween for dispensing. A slider is moveable along the legs to move the first and second flexible portions together to close the packaging. A method for opening and closing packaging for dispensing contents is also disclosed.

A bag container dispenser includes a bag container. The container is formed of resilient material and has a bottom, a top, first and second sides, a front, a back and a removable access panel. The access panel has a top segment that includes a portion of the top and a connected front segment. The front segment has a height that extends from the bottom to the top. Stacked bags are sized and shaped to fit within the bag container. Each of the bags has a front wall, a back wall, an open top and a closure mechanism. The bags are dispensable from the container through an opening provided by removal of the access panel which may have a removable cover. A dispenser rack has a horizontal platform sized and shaped to support the bag container. Peripheral guards extend upward from the platform and constrain movement of the container during dispensing.
