Description
Technical field
The present invention relates to a kind of latch piece, they are the label such as sealing label brand label, price tag, raw material manual, description on the commodity such as clothes, underwear, sundry goods, footwear, bag.Particularly relate to and be configured to following latch piece: for described commodity, once when the latch piece being closed above-mentioned label by ring-type filament is taken off, cannot again close.
Background technology
In order to tie up whole clothes, underwear, sundry goods, boots, sandals, footwear etc., or on these commodity, pasting brand label, price tag etc., all the time, using latch piece as shown in Figure 5.In Fig. 5 (A), latch piece 30 is formed by through label T-shaped filament portion 3 circlewise, the interspersed head 19 with blade (Block レ ー De) portion 6 possessed on one end and the socket part 2 had for the hole 10 through this interspersed head 19 that possesses on the other end in filament portion 3.
These are preferably one-body molded by synthetic resin etc., and especially, filament portion 3 is elongated, and has very strong hot strength.Represent in Fig. 6 (A) that interspersed head 19 is entrenched in the state in socket part 2, as shown in Fig. 6 (B), if the narrow interted in the completely through through hole 10 be arranged on socket part 2 of head 19, i.e. through overshooting shape forming portion etc. 23, the alar part part 6 as blade part then arranged near this interspersed head 19 is opened, thus, be positioned at the lock part 5 of this blade part 6 top ends and the jut 23 be arranged on this socket part 2 inner wall part kayser mutually, this interspersed head 19 is irreversible to shape at this socket part 2 internal fixtion, complete the label installment state of ring-type thus close.
In the past, such latch piece 30 tying up not only for boots, sandals or footwear, was mainly used on commodity, fix brand label or the label T with using method.But produce following problem recently: such latch piece is taken off wrongly, again replace item price label or the Counterfeit Item of itself and classic brands commodity is exchanged, or the classic brands stolen with this latch piece also replaces to other labels etc., the situation that the credit producing customer is deteriorated.
Such as, when department store or supermarket, sales field and cashier are positioned at independently local separately.Under such circumstances, because socket part 2 and the interspersed head 3 of existing latch piece can easily dismounting, therefore, it is possible to simply price tag T is replaced.Namely, such as, in the past due to the top ends of the interspersed head 19 of this latch piece 30, or the structure of the alar part part arranged near head and blade part 6 or jut 23 is more weak, therefore by applying tensile force large a little, then this alar part part and blade part 6 or jut 23 are out of shape, interspersed head can be extracted from this socket part 2, therefore, likely there is following situation: be arranged on label in this filament portion 3 or price tag T etc. and meet with stealing, or be replaced by other labels, price tag T, and again this interspersed head 19 is interted to this socket part 2 to return to original state.
In this case, because this interspersed head 19 there occurs sizable distortion, even if again this interspersed head 19 is interted to socket part 2, mostly can not easily intert, but situation about may intert is also a lot, even and if this interspersed head 19 is interted to this socket part 2, although do not ensure this interspersed head 19 to be firmly held in this socket part 2, but to the eye, owing to seeming as pacified normal latch piece, therefore third party is difficult to differentiate its difference, the problem that the Counterfeit Item of ropy commodity or classic brands commodity is such can be bought.
Therefore, in the past in order to solve the problem, such as known, latch piece 30 described in Unexamined Patent 11-167347 publication (patent document 1), near the junction surface of this filament portion 2 and this interspersed head 19 or in a part for the main part 4 of this interspersed head 19, the direction that central axis C with this latch piece 30 is vertical is formed crack or slit portion or groove 34 energetically, make the part that hot strength is low energetically, make this part 34 have tamper-proof (タ ン パ ー プ ル ー Off) effect.
In described latch piece 30, want the people stealing reputable brand label, or want the Counterfeit Item label people etc. installing reputable brand label in cheaper commodity, even if apply the tensile force of regulation to this latch piece 30, destroy the closed hoop shape of this filament and attempt replace this label or usurp, nubbin due to this interspersed head 19 remains on this socket part 2, and therefore this latch piece 30 cannot be returned to the closed form ring-type as original, therefore this tamper-proof effect normally plays.
On the other hand, in recent years, the extensive stock installing this latch piece 30 is the tendency of miniaturization or slimming, therefore, when StoreFront shows these commodity, the situation of this commodity overlap being shown is more, now, be subject to the thickness of this latch piece 30, the impact of thickness, also the overall volume deriving from the extensive stock of this displaying of sening as an envoy to becomes bulge that is large or this latch piece 30 and damages the problems such as this commodity surface, and then, while the cost of this latch piece 30 self is reduced, the CO produced with the discarded of industrial waste must be suppressed
2gas, for the expansion of green environment contributes, thus, with while must reducing the raw-material use amount of synthetic resin needed for this latch piece 30, for the purpose of the downsizing of this latch piece 30 self, require the miniaturization as shown in dotted line D in Fig. 6 (B), flattening.
Its result, owing to needing the width or the length equidimension that design this socket part 2 smaller, therefore, needs the length and the thickness that correspondingly reduce this interspersed head 19 with it.Now, because above-mentioned shear strength requires to need to maintain intensity as in the past, actual conditions are that the length of this interspersed head 19 can not too reduce.
And, about described latch piece 30 of the present invention, operators etc. are by manual operations, this interspersed head 19 is inserted in the through hole 10 of this socket part 2, require thus to avoid the hot strength of this latch piece 30 to decline, meanwhile, the interspersed possibility that overcomes when preferably being interted to this socket part 2 by this interspersed head 19 is little.
In the past, as the shape of the head 9 of this interspersed head 19, the latch piece 30 that general use is following: the overall latch piece 30 being bullet cut or spindle-type and not there is this blade part 6, such as, United States Patent (USP) No. 4059300 manual (patent document 2), Japanese Unexamined Patent Publication 10-116034 publication (patent document 3), the disclosed latch piece 30 such as Japanese Unexamined Patent Publication 9-207962 publication (patent document 4) or United States Patent (USP) No. 5738265 manual (patent document 5), and there is the latch piece 30 of this blade part 6 on the end of this cardinal extremity face 7, such as, Japanese Patent Publication 60-36588 publication (patent document 6), Japanese Patent Publication 1-36631 publication (patent document 7), United States Patent (USP) No. 5943741 manual (patent document 8), United States Patent (USP) No. 6009997 manual (patent document 9), the disclosed latch piece 30 such as United States Patent (USP) No. 6026544 manual (patent document 10) and United States Patent (USP) No. 6101683 manual (patent document 11), but this latch piece 30 of latter type when this interspersed head 19 is interted to this socket part 2, insertion force is less can be completed, therefore, expect to develop the latch piece 30 of the interspersed head 19 with described type, above-mentioned each problem points can be solved.
Further, in described latch piece 30, in the every profession and trade that commodity in use is different, this tamper-proof effect degree of this latch piece 30 is different, and the level of namely required preferred tamper-proof intensity is different, therefore, in each industry, the requirement for this hot strength degree of this latch piece 30 is different.
Therefore, by manufacturing arbitrarily the latch piece 30 of the regulation hot strength possessed needed for industry-by-industry, individually manufacture this latch piece 30 of this hot strength had needed for specific industry, can provide and also increase according to the necessity of indivedual industry requirement tool this latch piece 30 individual.

This latch piece 30 of the present invention is by suitable synthetic resin material, and such as, the synthetic resin materials such as nylon, polypropylene, polyethylene, forming processing technology that to utilize injection molding manner be main body is carried out one-body molded and formed.
Usually, latch piece 30 of the present invention, intensity is better high as far as possible, if but too improve the hot strength of this filament portion 3 and this interspersed head 19, stretch this filament portion 3 by force, there is breakage or distortion in the blade part 6 be made up of this alar part part etc. of this interspersed head 19 or jut 23, thus this closed solution can be made to remove, and also can carry out again closing as above, therefore it is not preferred, preferably do not occur, in damaged scope, to design this specific part and there is maximum hot strength in lock part 5 grade of this interspersed head 19.
On the other hand, as this latch piece 30, also exist and be used for tying up the situations such as boots, sandals, footwear, in this case, when commodity move, because sizable load is applied on this latch piece 30, therefore must avoid rupturing because of too small hot strength.
Therefore, this latch piece 30 of the present invention is configured to: if this latch piece 30 bears the tensile force of 4.0 ~ 8.0kg, then the fracture at least partially of this interspersed head 19.
Of the present inventionly be designed to the hot strength specific part more weak especially than other parts of this filament portion 3 and this interspersed head 19, be formed in this small diameter part 20 in this interspersed head.
That is, the present invention is configured to make this small diameter part 20 play tamper-proof effect.
And, latch piece 30 of the present invention, arrive observed by existing latch piece, the interspersed head 19 of this latch piece 30, for some reason, rupturing from the slit portion 34 specially arranged, as shown in Figure 5 (B), the inside remaining in this socket part 2 at least partially of this interspersed head 19, simultaneously, if the top ends of this cutting portion 70 is externally given prominence to from the side end edge edge of this socket part 2, the phenomenon then becoming above-mentioned existing issue occurs, but in the present invention, on this small diameter part 20 of this interspersed head 19, owing to have employed the structure that can actively and preferentially rupture, therefore, even if suppose when fracture occurs a part for this small diameter part 20 of this interspersed head 19, also can be as illustrated in fig. 7, the situation that its broken ends of complete wall is outstanding from this side end edge edge of this socket part 2.And, this latch piece 30 of the present invention, this apex 8 of this head 9 of this interspersed head 19 is made up of forniciform spherical surface body mild especially or tabular surface, therefore, it is possible to the thickness of this apex 8 is suppressed for lower, even the socket part 2 of the downsizing therefore as shown in the dotted line D of Fig. 6 (B), as shown in Figure 7, this apex also can be avoided completely to give prominence to such danger from this side end edge edge of this socket part 2.
In addition, in the present invention, can be configured to: even if when fracture occurs a part for the small diameter part 20 of the part as this interspersed head 19, at least the situation of residue in this socket part 2 of this head 9 and this small diameter part 20 also becomes many.
That is, by making a part of parts of this interspersed head 19 remain in the interspersed hole portion 10 of this socket part 2, can easily judge that this latch piece 30 is by damaged wrongly in the future.
That is, this latch piece 30 of the present invention, when being applied on this latch piece 30 by the tensile force of this regulation, can select this small diameter part 20, as the position playing this tamper-proof effect.
Namely, the invention is characterized in, it is designed to: interting to the hole portion 10 of this regulation of this socket part 2 by this interspersed head 19, when a part for this small diameter part 20 bears the tensile force of regulation, optionally form frangible portion for this tensile force energetically, make it easily rupture.

E size ... the part of A size and tamper-proofly have relation
(note: the radius of curvature of E size Expressing bending curve part R1 and R2)
F size ... the part of A size and tamper-proofly have relation
On the other hand, as the requirement project of user, there is project as follows in addition.
That is,
1. to thread a needle (ル ー プ ピ Application as senior hand) hot strength needed for bottom line is necessary for more than 4kg.
2. consider from the versatility of head size, the footpath, insertion hole in main flow hole is
Therefore, study further based on above-mentioned 2, result is:
(1) if consider above-mentioned project 1, in order to ensure the hot strength of this small diameter part 20, must be a certain C size.
Its value is preferably about 0.52mm;
(2) consider above-mentioned project 2, determine external diameter B size.
Its value is preferably about 2.49mm;
(3) in addition, according to the Mould Machining limit and mould strength, D size is determined.
Its value is necessary for about 0.33mm;
Thus, if consider above-mentioned each condition, the size that can be used in A size (having direct relation with tamper-proof) must be about 0.8mm.
That is, according to above-mentioned various research, above-mentioned necessary condition as consider this latch piece 30 ideal structure needed for necessary constitutive requirements occur, therefore, based on these necessary conditions, obtain the ideal form of this small diameter part 20 further.
That is, with reference to Fig. 4 and Fig. 9, further illustrate the preferred given shape of this small diameter part 20, according to the result of the test of type not having blade part, in order to ensure tamper-proof be that more than 4kg, A portion size is necessary for
above thickness.
But in the latch piece 30 of vane type, A portion size only has the space of 0.8mm to set.
Therefore, consider each problem points above-mentioned, the cross sectional shape using the space of 0.8mm can obtain this small diameter part 20 of the tamper-proof particular value of more than 4kg is studied.
As shown in Fig. 4 and Figure 10, about the cross sectional shape of this small diameter part 20, by changing the length of above-mentioned size F, various change is carried out to the section area of this small diameter part 20, to the hot strength how changed under each cross sectional shape, i.e. tamper-proof intensity, be studied in other words as tamper-proof value, as the design information of this part.
Certainly, also can to this small diameter part 20 with the length in the central axis C vertical direction of this length direction, namely the thickness of this small diameter part 20 changes.
In addition, when this F is of a size of zero, the circle that radius is R is become.
Carry out the result tested, as shown below.
From the above results, in the present invention, by adjusting this F size of this small diameter part 20, this latch piece 30 of the tamper-proof value had desired by user can easily be set.
In addition, when designing this latch piece 30 of the present invention, in fact change a little according to shape or shaping raw-material difference.
