Abstract
A zipper tape includes a male member and a female member that bite each other. The male member has a head, a projection at the tip of the head, and a recess located at a connecting portion between the projection and the tip of the head. The female member has first and second claw members facing each other, a valley between the first and second claw members, and a pair of protrusions located at the top of the valley. When the male member and the female member bite each other, at least a part of the inner surface of the first claw member of the female member and at least a part of the inner surface of the second claw member of the female member come into surface contact with at least a part of the surface of the head of the male member. The valley of the female member receives the projection of the male member, and the protrusions of the female member fit into the recesses of the male member.
Description
- The present invention relates to a zipper tape and a zipper-tape-equipped bag.
- A bag that can be freely opened and closed by providing, at its opening portion, a belt-shaped biting tool (zipper tape) comprising a male member and a female member is used principally in the food industry. Such a bag is also used as a bag for bedding or clothing.
- Patent document 1 has disclosed a zipper having a
male member 10 and afemale member 20 that bite each other, whereinpinch valves claw members female member 20, as shown inFIG. 6 . When biting, thepinch valves head 12 of themale member 10 so that themale member 10 and thefemale member 20 are kept in close contact. - However, the sealing performance of this zipper is inadequate because the male and female members are not in surface contact.
- Patent document 2 has disclosed a zipper comprising a
male member 30 and afemale member 40 as shown inFIG. 7 . In this zipper, ahead 32 of themale member 30 comes into surface contact with a part of the inner side surface of aclaw member 42 of thefemale member 40 and a part of the inner side surface of aclaw member 44 of thefemale member 40, and theclaw members head 32. - This zipper is improved in sealing performance because the male and female members are in surface contact, but this zipper has the following various problems.
- As the head of the male member is clamped by the tips of the claw members located apart from the base portion of the female member, clamping force is weak. If a load is applied to the tips of the claw members of the female member, the distance between the claw members increases, and the sealing performance may be impaired. When the claw members of the female member are so long as to touch the shaft of the male member, the claw members of the female member tend to be expanded at the boundary (the expanded claw members of the female member) of a fitted portion and an unfitted portion if the zipper is kept open for a long time, so that the sealing performance may decrease. The head of the male member is arc-shaped, which makes it difficult to align and fit the male and female members. If the zipper deforms at a side seal during the production of a bag, the sealing performance may be impaired, so that an advanced bag production technique is required during the bag production.

If the width a is smaller than the distance E, the male and female members are easily aligned when fitted together, and is easily fitted together. - The length c from the rear end of the male member to the front end of the male member is preferably greater than the length C from the top of the valley of the female member to the base of the clasp (see
FIGS. 3 and 4 ). If the length c is greater than the length C, the head lifts the clasps of the claw members, and contact pressure between the clasps and the clasp receptions increases. - Here, c is not easily recognized in the case of a curve shown in
FIG. 5 , inflection points of R of the projection and R of the recess are defined as ends. - The length D from the clasp of the female member is preferably equal to or less than half the length d of the clasp reception of the male member (see
FIGS. 3 and 4 ). If the clasp is shorter than the clasp reception, the claw members of the female member do not tend to be expanded and the sealing performance does not deteriorate even if the zipper is kept open for a long time. - In the configuration described above, dotted circular marks in
FIG. 2 indicate surface contact, and solid circular marks indicate contact pressure. - Here, if the width b of the head of the male member is greater than the distance B of the inner surfaces of the claw members of the female member (see
FIGS. 3 and 4 ), the contact pressure of surface contact between the claw members of the female member and the head of the male member preferably increases. - The zipper tape according to the present invention may include the arrangement of pairs of male and female zippers.
- The material of the zipper tape may be selected from materials that have heretofore been used for zipper tapes, for example, low-density polyethylene, straight-chain low-density polyethylene, ethylene-vinyl acetate copolymer, and polypropylene. For a high-sealing zipper, a soft resin such as polyethylene or ethylene copolymer is particularly preferable.
- The configuration described above allows the zipper tape according to the present embodiment to maintain sealing performance in various conditions in which the zipper tape is used. As long as the
protrusions 242 are in contact with theprojection 126 or therecesses 128, this zipper tape maintains sealing performance, and is therefore easily squashed. - A bag according to the present invention is equipped with the zipper tape described above.
