Abstract
Reclosable zipper arrangements for bags such as thermoplastic bags are described. The reclosable zipper arrangements are configured to advantageously provide a clicking sensory indicator, in the form of a tactile and/or audible indication of sealing, as zipper closure occurs. Package arrangements using the closure arrangements are described. Also, methods of assembly and use are described.
Claims22
A reclosable zipper closure arrangement useable in a reclosable plastic bag;
- the zipper closure arrangement comprising:
- (a) a first elongate base strip having a front side and an opposite back side;
- and,
- (b) a continuous, elongate, first male member on the front side of the first elongate base strip;
- (i) the continuous, elongate, first male member comprising a clicking sensory indictor male strip having a central rib with a continuous peak.
A reclosable zipper closure arrangement according to 1 including:
- (a) a continuous elongate first female member projecting from the front side of the first elongate base strip and spaced from the first male member.
A reclosable zipper closure arrangement for use in a reclosable plastic bag;
- the reclosable zipper closure arrangement comprising:
- (a) a first elongate base strip having a front side and an opposite back side;
- the first elongate base strip including:
- (i) a continuous, elongate, first male member on the front side of the first elongate base strip;
- (A) the continuous, elongate, first male member comprising a clicking sensory indictor male strip having a central rib with a continuous peak;
- and,
- (B) the continuous peak, of the central rib, having a maximum cross-sectional height H, in extension from the back side, that does not vary by any more than 0.2 mm along a length of extension of at least 4 cm, not including any end distortion;
- and,
- (b) a second elongate base strip having a front side and an opposite back side and having:
- (i) a first female member comprising a continuous recess located between first and second, opposite, hook sides;
- (A) the first female member being positioned with the first male closure member projecting into the continuous recess.
A thermoplastic pouch arrangement comprising:
- (a) first and second panels defining a pouch arrangement having:
- opposite, closed, sides;
- a closed bottom end;
- and, an open top end;
- and,
- (b) a reclosable zipper closure arrangement positioned between the first and second panels and comprising:
- (i) a first elongate base strip having a front side and an opposite back side;
- the first elongate base strip including:
- (A) a continuous, elongate, first male member on the front side of the first elongate base strip;
- (1) the continuous, elongate, first male member comprising a clicking sensory indictor male strip having a central rib with a continuous peak;
- and,
- (2) the continuous peak, of the central rib, having a maximum cross-sectional height H, in extension from the back side, that does not vary by any more than 0.2 mm along a length of extension of at least 4 cm, not including any end distortion;
- and,
- (ii) a second elongate base strip having a front side and an opposite back side and having:
- (A) a first female member comprising a continuous recess located between first and second, opposite, hook sides;
- (1) the first female member being positioned with the first male closure strip projecting into the continuous recess.
A method of modifying a closure strip of a reclosable zipper closure arrangement for use in a reclosable plastic bag;
- the method comprises a step of:
- (a) passing a continuous closure strip section comprising a continuous, elongate, male closure member having a continuous rib and continuous peak into a first groove of a roller while distorting the male closure member to create alternating first and second sections;
- (i) in each one of the plurality of first sections, the side arm arrangement comprises opposite side arms projecting away from the central rib and defining female side hook receivers on opposite sides of the central rib between each side arm and the first elongate base strip;
- and,
- (ii) in each one of the plurality of second sections, the side arm arrangement comprises side arms projecting along the rib and toward the first elongate base strip to avoid the presence of female side hook receivers between the side arms and the first elongate base strip;
- and,
- (b) the step of passing including:
- (i) passing the male closure member into a first roller groove having alternating narrow and wide sections, to generate the alternating first and second sections;
- and,
- (ii) providing a resulting male member that has a continuous peak
