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 zipper slider with an automatic resetting and locking function comprises an upper plate and a lower plate, further comprises a torsion member, an elastic piece, a first elastic member and a second elastic member, the elastic piece is provided with an acting end and a locking pin end, the torsion member is movably connected to the upper plate and located above the elastic piece; a bottom of the torsion member is provided with an avoidance notch adapted to the acting end, and torsion of the torsion member can drive the second elastic member to undergo elastic deformation; a user only needs to twist the torsion member while pulling the zipper slider in the present invention, and the user releases the hand, the zipper slider automatically resets to be locked, this increases the unlocking difficulty and reduces the probability of articles being stolen.

A container sealing system and a container feature are disclosed. The container sealing system includes 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 including 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 including 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 include a tamper-indicating feature. The container including the container sealing system may be used for containing, storing, or transporting materials that are not suitable for handling or consumption by a child.

A slider for a slide fastener includes a slider body (11) and two pullers (20, 21) pivotally attached to the slider body (11). The slider body (11) forms an upper wing (12), a lower wing (13), a connecting post (14) connecting the upper and lower wings, and side flanges (15). The side flanges protrude from side edges of the upper and lower wings towards a geometrical mid-plane (P) that lies between the wings (12, 13), so as to form a Y-shaped channel (19) between the upper and lower wings. The upper wing (12) and the lower wing (13) have respective opposite outer surfaces (23, 24) which are substantially flat, and are symmetrical with respect to the geometrical mid-plane (P). At least one locking protrusion (30) protrudes inwardly into the Y-shaped channel (19) from at least one of the side flanges (15) of the slider body (11).

A slide fastener slider includes: a lower member; an upper member; a cover; and a pull tab. The lower member includes a lower blade, a guide column, an upper plate portion, and an attachment column. The upper member includes a flat plate portion, an opening portion, and a placement portion. The cover includes, at an end portion thereof in the front and rear direction, an engaging portion engaged with an engaged portion provided on the attachment column. A shaft portion provided at one end of the pull tab is disposed in a space formed between the upper plate portion and the cover. The placement portion is sandwiched between the engaging portion of the cover and the upper plate portion by attaching the cover to the attachment column by engaging the engaging portion of the cover with the engaged portion of the attachment column.
