A child resistant zipper closure for a bag includes a slider having a flexible tab with a torpedo. To open a zipper closure, the tab must be held in a downward position to engage the torpedo between male and female tracks and result in separation of interlocked complementary profiles, while the slider is moved along the zipper closure.

A technique for forming a releasable attachment provides first and second latch strips each having an alternating pattern of lobes and troughs. The lobes of the first latch strip are adapted to fit within the troughs of the second latch strip, and vice versa, with the lobes retained within the troughs until sufficient force is applied between the first and second latch strips to separate them.

The invention discloses a flat bottom resin zipper, which injects resin chain teeth onto a core wire or a chain cloth. Each resin chain tooth has a sewing thread slot on the top and a chain cloth embedding groove on the bottom. Then sew the entire resin chain teeth to the chain cloth, so that the sewing threads are tightened in the sewing thread slots, and the chain cloth is embedded in the chain cloth embedding grooves, forming a double fixed structure of injection molding and sewing thread sewing. Afterwards, the inner side of the chain cloth is folded back to form a flat bottom zipper with only the chain cloth on one side of the zipper without any protruding resin chain tooth, which can be used as an anti-pinch zipper or an invisible zipper.

A zipper structure is provided and includes a first zipper component including a first zipper portion, a second zipper component including a second zipper portion, and a sealing end assembly. An end part of the first zipper portion of the first zipper component adjacent to an end of the first zipper component and an end part of the second zipper portion of the second zipper component adjacent to an end of the second zipper component are engaged with each other. The sealing end assembly is connected to the ends of the first zipper component and the second zipper component by injection molding and covers surfaces of the ends of the first zipper component and the second zipper component. A gap between the end parts of the first zipper portion and the second zipper portion is filled with the sealing end assembly. Furthermore, a related zipper bag is also provided.

A fastening system includes two elongated profile parts, one of which includes a guiding surface or ramp for positioning it with respect to the other profile part, for releasably fastening a carrier to a holder. Deformations of a rib of one profile or a clamping hole of the other profile are adapted to position the one profile in substantially clamped state in the other profile in the longitudinal direction.
