Abstract

Disclosed is a zipper tape comprising male elements and female elements that interlock. Each male element has a head, a protrusion at the tip of the head, and concavities at the points where the head and the tip thereof meet. Each female element has first and second claw parts that face each other, a pocket between the first and second claw parts, and a pair of prongs at the top of the pocket. When a male element and a female element interlock, at least part of the inner surfaces of the first and second claw parts on the female element make surface contact with at least part of the surface of the head on the male element; the pocket in the female element receives the protrusion on the male element; and the prongs on the female element engage with the concavities in the male element.

Description

The sack of zipper tape and band zipper tape
Technical field
The present invention relates to the sack of a kind of zipper tape and band zipper tape.
Background technology
The seal opening portion of sack be provided with the clamping device (zipper tape) of the band shape that constitutes by male parts and female part and but the sack of freely openable mainly uses at field of food.In addition, also can be used for bed clothes sack, dress material sack.
As shown in Figure 6, patent documentation 1 discloses a kind of buckle that makes male parts 10 and female part 20 interlocks, this be buckled in female part 20 tine 22, be provided with clamping lobe 25,26 between 24.When interlock, push away the head 12 of male parts 10 in clamping lobe 25,26 clampings also, make male parts 10 and female part 20 keep tight state of contact.
But, because male and female members does not carry out the face contact in this buckle, so sealing is insufficient.
A kind of buckle that is made up of male parts 30 and female part 40 as shown in Figure 7 is disclosed in the patent documentation 2.In this buckle, the head 32 of male parts 30 contacts with a part of generating plane of the inboard side surface of the tine of female part 40 42,44, tine 42,44 fastening heads 32 and sealing.
This buckle improves sealing because male and female members carries out the face contact, yet has following variety of issue.
Through away from the fastening force of the head of the fastening male parts in top basal part, tine of female part a little less than.In case to the top imposed load of the tine of female part, then the interval of tine may become greatly, sealing may be impaired.The tine of female part is long under situation about can touch with being coupling of male parts; If buckle keeps open state for a long time; Then possibly appear at telescoping part and be the defective of enlarged state, cause sealing to descend with the tine of the intersection of telescoping part (tine of female part is enlarged state) female part not.The male parts head is circular-arc, is difficult to make the aligned in position of male and female members to carry out chimeric when chimeric.In the side seal process when bag,, thereby need higher bag technological during bag in case buckle distortion just may damage sealing.

The specific embodiment
Below, with reference to accompanying drawing, the present invention will be described according to embodiment, however embodiment is merely illustration, and the present invention does not receive the restriction of embodiment.
Fig. 1 representes the zipper tape of an embodiment of the present invention.This zipper tape is made up of engaged male parts 100 and female part 200.
Male parts 100 comprises base portion 110, head 120 and the bar-shaped connecting portion 130 that connects base portion 110 and head 120.It is approximate hemispherical that head 120 is, and has top ends 122 and surface, back 124.Approximate hemispherical hemispherical, heart and the arrow-shaped etc. of comprising.
Head 120 back surperficial 124 bigger than the cross section of connecting portion 130, the substantial middle on the back surface of head is connected with connecting portion.Back surperficial 124 of the head that is not connected with connecting portion 130 is formed with hook carrier 124.
Has protuberance 126 on the top ends 122 of male parts 100.In the coupling part of top ends 122 and protuberance 126, be that the root of protuberance 126 has recess 128.
Female part 200 has: base portion 210; Relatively to first and second circular-arc tine 220,230; And the hook portion 222,232 of giving prominence to ground relatively from the top of first and second tine 220,230.The length of this hook portion 222,232 is shorter than the hook carrier 124 of male parts.First and second tine 220, has the recess 240 of the protuberance 126 of the top ends that is used to accept male parts between 230.The top of recess 240, be that the root of tine 220,230 has a pair of projection 242.
As shown in Figure 2, when male parts 100 was inserted into female part 200, the protuberance 126 of the top ends of male parts entered into the recess 240 between first and second tine, and the recess 128 of male parts is chimeric with a pair of projection 242 of female part.In addition, first and second tine 220,230 of female part relatively at least a portion of inner surface contact with at least a portion face on the surface of the head 120 of male parts.Improve tight contact through this state.
In addition, at the recess between female part 240, the fastening force of the protuberance 126 of fastening male parts head is stronger.
In addition, about male parts shown in Figure 7 30, because the top ends of head 32 is more smooth circular-arc; So may occur that the position is mismatched and situation about getting loose, still, in this embodiment; Its top ends 122 is formed with protuberance 126; 222,232 pairs of these protuberances 126 of hook portion lead, and thus, make the position of male and female members 100,200 cooperate more or less freely.
When male parts 100 and female part 200 interlocks, the hook portion 222,232 of female part contacts with the hook carrier 124 of male parts, is preferably the face contact.Thus, further improve sealing.
In this embodiment, preferably, the width a of the protuberance of male parts is than the width A of the projection of female part wide (with reference to Fig. 3,4).Width a is wideer than width A, pushes away male parts on the female part, and projection 242 rises with the contact pressure of recess 128 and the contact pressure of hook portion 222,232 and hook carrier 124.
In addition, preferably, the width a of the protuberance of male parts is than the interval E on the summit, top of the tine of female part little (with reference to Fig. 3,4).During width a ratio interval E, the position of male and female members cooperates easily when chimeric, is easy to chimeric.
In addition, preferably, the length c from the back endmost surface of male parts to the top of male parts than from the top of the recess of female part to the length C big (with reference to Fig. 3,4) of the root of hook portion.When length c is bigger than length C, the hook portion of the parts of pawling on the head, the contact pressure of hook portion and hook carrier rises.
Here because c is as shown in Figure 5, be difficult for during for curve understanding, so with the turning point of the R of the R of protuberance and recess as the top.
Preferably, the length D of the hook portion of female part is (with reference to Fig. 3,4) below length d half the of hook carrier of male parts.Hook portion even buckle keeps open state for a long time, the defective that the tine of female part broadens can not occur than hook carrier in short-term yet, and sealing can not descend yet.
In above-mentioned formation, the circular mark presentation surface contact of the dotted line among Fig. 2, the circular mark of solid line is represented contact pressure.
Here, preferably, when making the width b of head of male parts bigger than the width B of the inner surface of the tine of female part (with reference to Fig. 3,4), the contact pressure that the tine of female part contacts with the face of the head of male parts rises.
Zipper tape of the present invention can be arranged many buckles that negative and positive are paired.
The material of zipper tape selects the employed low density polyethylene (LDPE) of existing zipper tape, straight chain shape low density polyethylene (LDPE), ethylene-vinyl acetate copolymer, polypropylene etc. to get final product; Especially; In the buckle of high leakproofness, the resin that polyethylene or ethylene copolymer etc. are softer is comparatively preferred.
Through above-mentioned formation, the zipper tape of this embodiment can keep sealing in various environments for use.In addition, because this zipper tape can keep sealing as long as protuberance 126 or recess 128 contact with projection 242, so be easy to flatten.
Sack of the present invention is equipped with above-mentioned zipper tape.
