Description

The splicing tape that can peel off

Technical field

Thereby the present invention relates to be elongated with base material the splicing tape that can peel off of peeling off from the face of being stuck by what apply that tension load makes to have caoutchouc elasticity, more particularly, relate to the splicing tape that can peel off that can strip simply by less power.

Background technology

As having the splicing tape that can peel off pasting when placard not one of the method that can damage metope as drawing pin etc. and paste.For example, as shown in patent documentation 1 (Japanese Patent Publication 2004-339353 communique), the surface with base material that the splicing tape that can peel off is made up of the snappiness sheet by foamex or rubber-like is coated with the splicing tape of caking agent and makes, and is clipped between metope and placard and uses.

In the time pulling down the splicing tape that this can peel off, catch and be arranged at the handle part of strap end portion and it is pulled out laterally with hand.Thus, band base material extends and is out of shape, and bond area reduces thereupon gradually, and last splicing tape peels off from metope.Thus, can not pollute metope etc. and strip neatly.In addition, also can reclaim simply the band using.

But, in the existing splicing tape that can peel off, there is following problem., the non-cementability sheet of fitting in one end of the face that is stuck of the splicing tape of rectangle of the splicing tape that can peel off up to now, using this non-cementability sheet as handle part dominated by hand.Therefore, handle part is identical with the width of attaching portion, so the stretching force of per unit is large, need to strongly stretch.And, because handle part self also extends, so also there is the long shortcoming of extended distance.

In addition, in the case of using this splicing tape that can peel off as for hook is waited and is arranged on fixed mechanism on metope, in the time of dismounting, the splicing tape that can peel off is also sometimes under the effect of the impetus being stripped from, fly to finger with the base plate of the hard for hook is installed etc., thereby likely do pain finger.

Summary of the invention

Therefore, the present invention completes in order to solve above-mentioned problem, and its object is, provides and can prevent that band is towards the finger splicing tape that can peel off sudden, that also can utilize little power to dismantle simply in the time peeling off.

In order to achieve the above object, the present invention possesses several features shown below.The splicing tape that can peel off described in first aspect present invention is by forming bond layer and form having elastic single or double with base material, thereby this splicing tape is elongated from the face of being stuck above-mentioned band base material to peel off by applying tension load, it is characterized in that, be provided with continuously integratedly along one end of above-mentioned attaching portion of pasting with the above-mentioned face that is stuck of base material the non-bonding handle part of being held by handgrip, the width of above-mentioned handle part is formed as being greater than the width of above-mentioned attaching portion, be provided with the linking part that the width of above-mentioned attaching portion and the width of above-mentioned handle part are gradually changed in the end linking with above-mentioned attaching portion of above-mentioned handle part.

As preferred mode, above-mentioned linking part right and wrong are bonding.In addition, preferably above-mentioned linking part is implemented for making it be difficult for the non-prolonged treatment of extension.In addition, as alternate manner, above-mentioned handle part is arranged at the two ends of above-mentioned attaching portion via above-mentioned linking part.

According to the present invention, by making the width of attaching portion be less than the width with base material of handle part, and the linking part that setting gradually changes its width between attaching portion and handle part, thereby the tensile stress that makes to be applied on handle part concentrates on the root of handle part and attaching portion, thereby can strip efficiently with little power.

Embodiment

Below, with reference to accompanying drawing, embodiments of the present invention are described.Fig. 1 is front view and the side-view of the splicing tape that can peel off of an embodiment of the invention, Fig. 2 is the schematic diagram that represents the variation of the above-mentioned splicing tape that can peel off, Fig. 3 is the front view of the embodiment of splicing tape and the sample of comparative example, and Fig. 4 represents the photo of state the extending with 100% pitch from original state of embodiment and comparative example and the table of the deflection at each position thereof.

As shown in Figure 1, the splicing tape 1 that this can be peeled off, by forming at the elastic two-sided double-sided adhesive tape splicing that is formed with bond layer (attaching portion) 3,3 with base material 2 with appropriateness, is provided with in one end (lower end in Fig. 1) of lengthwise direction the handle part 4 of being held by handgrip in the time peeling off integratedly via linking part 5.

Be preferably easy extension and peel off and have the synthetic resins of appropriate caoutchouc elasticity with base material 2, in this example, formed by the foamed sheet that uses the crosslinked crosslinked polyolefin resin forming of metallocene class catalyzer with base material 2, as long as have but possess the appropriate caoutchouc elasticity that extends separability, the material with base material can at random be selected according to specification.In addition, the formation of foamed sheet can be any in continuous air bubbles and separated foam.

In the time the width of the attaching portion 3 of the face stickup that is stuck along metope etc. being made as to W1, the width of handle part 4 is made as to W2, the width W 2 of handle part 4 is formed as being greater than the width W 1 (W2 > W1) of attaching portion 3.

The linking part 5 being arranged between attaching portion 3 and handle part 4 is formed as, and its lateral margin is reduced to the width W 1 of attaching portion 3 gradually from the width W 2 of handle part 4, be formed as in this example trapezoidal.Linking part 5 is preferably at least than a little less than the bonding force of attaching portion 3, more preferably non-bonding.

In this example, linking part 5 forms with handle part 4, is fitted with polyester film and becomes non-bondingly on the surface of this linking part 5, but in addition, as long as making to comprise that the handle part 4 of linking part 5 is non-bonding method, can suitably select.

Thus, by linking part 5 is set, make, extending the stress concentration applying while peeling off in attaching portion 3, can make thus attaching portion 3 tensile deformation equably.And, by making the bonding force of linking part 5 more weak or become non-bondingly than attaching portion 3, attached thing and peel off and bring the situation of impact to suppress for inferior limit to extension thereby linking part 5 can be pasted on.

As the mode being more preferably, preferably linking part 5 is implemented for making linking part 5 be difficult for the non-prolonged treatment of extension.As non-prolonged treatment, can or assemble integratedly the strengthening part such as sheet and net by the surface at linking part 5 or inner laminating, improve the rigidity of linking part 5.

In addition, the two-sided spacer (not shown) that is provided with

protection bond layer

3,3 of the splicing tape that can peel off 1 in the time not using, in the present invention, spacer can form arbitrarily, therefore omits its diagram and explanation.

Bond layer

3,3 has high retentivity, be coated with have can with the ductile caking agent of synchronizeing with the crosslinked polyolefin resin of base material 2.In this example, caking agent is by being directly coated in the polymkeric substance of SBS segmented copolymer class on the surface with base material 2 and forming equably with pre-determined thickness.In this example,

bond layer

3,3 is formed as the thickness of 0.1mm.

In this example, for caking agent, using the polymkeric substance of SBS segmented copolymer class as female agent, be added with caking agent composition, the naphthenic wet goods such as α pinene vinyl resin and C5C9 petroleum resinoid, and be further combined with the various additives such as oxidation inhibitor and UV light absorber.

More preferably in caking agent, be also added with isocyanate resin, thus, be combined securely with the surface treatment with base material, therefore, boundary strength is higher, can improve anchoring.

Further preferably in caking agent, coordinate the silica bead (silica beads) of predetermined amount.In this example, caking agent is solvent based, therefore, use the silica bead with solvent resistance, but wherein, hydrophobicity silica bead, to the good dispersity of solvent based adhesives, is therefore more preferably.

Handle part 4 is by the synthetic resin film of non-cementability 41,41 is fitted in respectively with the two sides of base material 2 and is formed, and forms symmetrically.In this example, handle part 4 consists of the surface that

polyester film

41,41 is fitted in to

bond layer

3,3, but for dominated by hand, as long as be non-cementability, also can be for example not on band base material 2 adhesive-applying

layer

3,3 ground form.

In this example, handle part 4 is connected integratedly with the one end (lower end) with base material 2, but in addition, also can be arranged at respectively as illustrated in fig. 2 the two ends of the lengthwise direction (bearing of trend) with base material 2.This mode is also contained in the present invention.

Thus, by the

handle part

4,4 at two ends dominated by hand, they are extended to the direction that mutually deviates from, carry out thereby make to peel off from two ends towards central authorities, therefore, can prevent reliably that the bottom of front end or hook etc. of above-mentioned splicing tape is sudden towards on hand.

Then, an example of the use step to this splicing tape 1 describes.In the time using this splicing tape 1, first, strip not shown spacer so that bonding plane (attaching portion 3) exposes, this attaching portion 3 is pasted by attaching face along one.

Then,, by another is fitted in another attaching portion 3 by attaching face, remained on metope thereby will attach thing.Now, linking part 5 and handle part 4 are to configure from the mode of being avoided by attaching thing.

Thus, attached on thing by only attaching portion 3 being sticked on, thereby controlling handle part 4 while stretching, make tensile stress concentrate on attaching portion 3 by linking part 5, can make attaching portion 3 be out of shape equably.

After use, the handle part 4 being stretched out from attaching thing dominated by hand, pushes down lightly on one side and is attached thing, the handle part 4 that stretches on one side, and thus, this tensile stress concentrates on attaching portion 3 by the tapering of linking part 5, thereby can utilize little power that attaching portion 3 is extended.

[embodiment]

Then, the specific embodiment of the splicing tape that can peel off of the present invention is compared to research together with comparative example.

First, as embodiment, prepare the band base material of the foamed sheet of crosslinked polyolefin resin, making stamping-out becomes the sample of No. 3 dumbbell shapes (with reference to Fig. 3 (a)) of recording in JIS-K6251.And, as a comparative example, prepare the sample that utilizes identical band base material stamping-out to become the oblong-shaped (with reference to Fig. 3 (b)) of width 5mm × length 100mm to form.From the medullary ray of the lengthwise direction (bearing of trend) of each sample, draw 4 mark lines in left and right with the interval of 10mm.

[tension test]

The two ends 10mm of each sample is clipped on tensile testing machine, draw speed with 300mm/min offers tension test, elongation with 100% pitch extends 0～700%, measure respectively the interval (embodiment: a1～d1 of the mark line of each elongation state, comparative example: a2～d2) and the width (embodiment: e1, comparative example: e2) of attaching portion.

Below, its result is shown.

Fig. 4 represents the gathering of result of embodiment and comparative example.And Fig. 5 (a) illustrates the chart of the variation of expression extended distance-bandwidth, Fig. 5 (b) illustrates the chart of the relation that represents elongation and fracture.

Can obtain following opinion by foregoing.

For embodiment, the attaching portion of central authorities is thin, and thus, tensile stress concentrates on attaching portion, and therefore, the elongation of central part (a point) is large, and along with towards handle part, elongation diminishes, and thus, uses little power also can strip efficiently.

And, for embodiment, due to from two ends towards central authorities, the thin portion of width also becomes greatly, therefore more easily peels off.

For comparative example, because a point～d point shows uniform elongation, therefore, if start not continue to stretch with constant stretching force to peeling off end from peeling off, cannot peel off.Therefore, owing to extending equably, therefore also not too decay of the thin portion of width.

The splicing tape of embodiment, compared with comparative example, caters to fracture with 60% extended distance.

Thereby the splicing tape 1 that can peel off is as long as at least at one end possessing handle part 4, by stretching handle part 4 by the splicing tape of that face is peeled off from being mounted, the so-called extension stripping type of splicing tape, and these various variation are also contained in the present invention.
