A baby onesie to be worn by a baby includes a body covering material configured to cover a body of the baby, the body covering material including an opening through which a head of the baby can protrude. The baby onesie further includes a neckline provided around a perimeter of the opening, the neckline including a neckline fastener configured to be fastened and unfastened to thereby close and open the neckline, respectively. The baby onesie also includes a zipper configured to open and close the body covering material, and a zipper locking mechanism configured to selectively attach the neckline fastener and the zipper to lock the zipper in place to the neckline fastener.

A luggage article, such as luggage case, with zipper pull-tabs laterally engaged along inner sides and separably secured by a magnetic force, without interlocking with each other, to allow enhanced manipulation of the zipper pull-tabs, zipper sliders and optionally improved operation of the lock mechanism.

There is provided a slider for a slide fastener. The slider includes a body, a pull tab, a shaft member, and a coil spring. The pull tab has a base portion, a gripper and a claw portion protruding from the base portion. The shaft member is configured to rotatably support the pull tab relative to the body. The coil spring is attached around the shaft member to urge the gripper to be laid down toward the body. A claw guide portion allows a tip end of the claw portion to protrude into the guide groove. A restricting portion of the body restricts rotation of the pull tab when the pull tab is raised by a predetermined angle from the body. A restricted portion of the pull tab comes in contact with the restricting portion when the pull tab is raised by the predetermined angle from the body.

A slider, includes a slider base, a pull-tab, a connecting shaft and a spring; the slider base includes an upper blade, a lower blade, and a connecting pin connecting the upper blade and the lower blade; said pull-tab is integrated with the connecting shaft; the pull-tab includes a pull-tab body, with a spring mounting part and a locking part set at the anterior-end-face of the pull-tab body; the anterior-end-face of the pull-tab body is set as a locking vertical plane and the bottom of the pull-tab body is set as cambered surface; the connecting shaft is fixed to the anterior-end of the pull-tab body and the length of the connecting shaft is larger than the width of the anterior-end-face of the pull-tab body; the connecting shaft runs through the spring mounting part and the locking part and extends to both sides of the anterior-end of the pull-tab body.

Locking pull-tabs for a zipper include a first pull-tab that may be connected to a first slider and a second pull-tab that may be connected to a second slider of the zipper. The first pull-tab and second pull-tab include a first locking coupler and a second locking coupler, respectively. The first locking coupler and second locking coupler may enable the first pull-tab and second pull-tab to engage each other in a manner that secures a zipper in a closed arrangement and, thus, provides some security to contents of an item that are enclosed in the item with the zipper. The first locking coupler and second locking coupler may engage each other in a manner that requires intentional and conspicuous manipulation of the first pull-tab and second pull-tab to uncouple them. Methods for locking a zipper are also disclosed.

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.

An extensible lock pull includes: a pull main body including, at one end thereof, a slider connecting portion; a lock head; and a position limiting buffer member. The pull main body is provided with a sliding groove extending along a length direction thereof. The lock head is movably connected to the sliding groove along an extending direction of the sliding groove. The pull main body is provided with an attachment opening portion in communication with the sliding groove at an end of the sliding groove. The lock head is connected to the sliding groove through the attachment opening portion. The position limiting buffer member is fixed to the pull main body and blocks the attachment opening portion. The pull main body and the lock head are both metal parts. The position limiting buffer member is a plastic part or a rubber part.

A slider for a slide fastener includes: a metal slider body which includes an upper blade, a lower blade, and a connecting column connecting the upper blade and the lower blade at front sides thereof, a stringer passage which allows facing side edge portions of a pair of fastener stringers to pass therethrough being formed on an inner side of the slider body; and a component which is accommodated in the slider body. The slider body includes a recess which is recessed on a surface of the slider body and in which the component is accommodated, and a dedicated vent hole which allows ventilation between an outside of the slider body including the stringer passage, which is outside the slider body, and an inside of the recess.

A baby onesie to be worn by a baby includes body covering material configured to cover a body of the body, the body covering material including an opening through which the baby's head can protrude out from, a neckline provided around a perimeter of the opening, the neckline including a neckline fastener configured to be fastened and unfastened to thereby close and open the neckline, respectively, a zipper configured to open and close the body covering material, and a zipper locking mechanism attached to the zipper, the zipper locking mechanism configured to selectively attach to the neckline fastener and thereby lock the zipper in place according to whether the neckline fastener is fastened or unfastened.
