The first convex body has two convex ribs and two convex portions disposed on a top side of the first sliding body to respectively adjacent to the two convex ribs. A movable cover body has two sliding portions respectively movably contacting the two convex ribs and respectively separately contacting the two convex portions. A zipper head assembly structure using the sliding member is further provided.

The instant disclosure provides a zip slider structure including a slider body, a tab-holder and a pull-tab arranged between the tab-holder and the slider body. The slider body includes a first slide portion, a second slide portion and a connecting portion including a joint recess. The first slide portion includes a first slide surface, an arranging surface, a first recess, a second recess and a first extension end. The tab-holder includes a body portion, a first bending portion extending from one end of the body portion and passing the first recess, and a second bending portion extending from the other end of the body portion. The first bending portion includes a slot joining with the first extension end, the second bending portion includes a holding end joining with the joining recess, the body portion includes an attaching member extending from the body portion and joining with the second recess.

A continuous element slide fastener, which includes: a pair of support tapes, arranged in parallel, wherein a gap is formed between the pair of support tapes, each of the support tapes is formed with a first surface and a second surface which are oppositely arranged; and a pair of continuous-type coupling elements, respectively disposed at an inner edge of each of the second surfaces of the pair of support tapes, wherein each of the continuous-type coupling elements is formed with a connection surface and a fastening surface which are oppositely arranged, and the connection surface is formed with a first protrusion; when the slide fastener is in a coupled status, the highest positions of the first protrusions of the pair of continuous-type coupling elements are located in the gap, and the highest positions of the first protrusions are higher than the second surfaces.

Access-limiting mechanism limits access to a container. Access is controlled by moving a slider back and forth along a plastic zipper, opening and closing the zipper. The access-limiting mechanism includes, in addition to the slider, a coupler. The coupler can stay fixed, immovable, at a given location, relative to the zipper; or can be moved along the length of the zipper. As the slider moves close to the coupler, the slider and coupler are coupled to each other, limiting the ability of the slider to open the zipper. Access can be further limited by adding a second control mechanism such as a cover which overlies, optionally latches to, one or both of the slider and the coupler. To open the container, the slider and coupler, and/or as applies the cover, are released from respective coupling arrangements. Then, the slider can be moved away from the coupler to open the container.

A zip slider (1) is described comprising a slider body (110); a lock mechanism (200) for locking the sliding movement of the slider (1) that is positioned in the slider body (110) and comprising a movable stop element (210) for stopping the sliding movement of the slider (1) in a longitudinal direction and in the zip opening direction and a release button (300) for unlocking the lock mechanism (200), slidably mounted in the slider body (110) and manually operable to unlock the lock mechanism (200).

A container sealing system and a container feature said container sealing system are disclosed. Said container sealing system comprises one or more seals encompassing a container opening, wherein the one or more seals are interlockable or otherwise engageable to seal the container when activated; a first slider head comprising a male fitting coupled to the one or more seals; and a second slider head coupled to the one or more seals and opposing the first slider head, and comprising a female fitting for receiving and coupling the male fitting. Actuation of at least one of the slider heads such that the male fitting contacts the female fitting couples the one or more seals encompassing the container opening, sealing the container. The container sealing system may be child-resistant, may be resealable, and/or may comprise a tamper-indicating feature. The container comprising the container sealing system may be used for containing, storing, or transporting materials that are not suitable for handling or consumption by a child.

The present disclosure provides a sliding member including a first sliding body, a second sliding body opposite to the first sliding body, a connection body connected between the first sliding body and the second sliding body, a first convex body disposed on the first sliding body, and a second convex body disposed on the first sliding body. The first convex body has two convex ribs and two convex portions disposed on a top side of the first sliding body to respectively adjacent to the two convex ribs. A movable cover body has two sliding portions respectively movably contacting the two convex ribs and respectively separately contacting the two convex portions. The instant disclosure further provides a zipper head assembly structure using the sliding member.
