Description

  The present invention relates to a label sheet.

Conventionally, as a label sheet, a release sheet is overlapped so as to cover an adhesive layer of an adhesive sheet having an adhesive layer, and the adhesive sheet is formed with a slit capable of separating the label. (See Patent Document 1).
In order to peel off the label from such a label sheet, for example, a region near the corner of the label is curved with the release sheet side inward, and only the corner of the label is lifted from the release sheet. The label is peeled off from the release sheet by picking and pulling the corner of the label with a finger. At that time, the adhesive material is too strong or the elasticity of the label is weak. In some cases, the corners of the label are difficult to lift from the release sheet, and it is difficult to create an opportunity to peel off the label.

  Therefore, the present applicant has proposed the following configuration in Patent Document 2 in order to solve the above problem. That is, for example, as shown in FIG. 10, a release sheet part removal slit 31 is formed on the release sheet 30 side so as to cut through a plurality of label separating slits 22 formed in the adhesive sheet 20. The perforations 11 are formed so as to continue from the edge portions of the sheet 20 and the release sheet 30 to the label separating slit 22. In addition, an auxiliary slit 32 that connects the perforation 11 and the release sheet portion removal slit 31 is formed at a position in the release sheet 30 that overlaps the label separation slit 22 of the adhesive sheet 20. When the label 23 is peeled off, first, the both sides of the perforation 11 are picked with fingers and pulled so that the perforation 11 is opened, and the label 23 is cut to the slit 22 for separating the label. Then, from the intersection of the perforation 11 and the label separating slit 22, the slit is cut along the auxiliary slit 32 to the release sheet portion removing slit 31. Thereafter, when the release sheet 30 is pulled in the direction in which the release sheet 30 is peeled off from the pressure-sensitive adhesive sheet 20 (the direction along the release sheet part removing slit 31), the right side portion of the release sheet 30 can be peeled off from the pressure-sensitive adhesive sheet 20 23 is in a state in which a part of the pressure-sensitive adhesive layer 21 is exposed while part of the adhesive 23 is attached to the release sheet 30 (see FIGS. 11 and 12). With this state, the label 23 can be easily peeled off from the release sheet 30.

However, in the label sheet 10 having the above-described configuration, when a part of the release sheet 30 is peeled off from the pressure-sensitive adhesive sheet 20, the following problems are concerned. That is, when the adhesive strength of the pressure-sensitive adhesive layer 21 is strong, the label sheet 10 is cut from the edge portion along the perforation 11, and the leading end of the cut portion is released from the label separating slit 22 and the auxiliary slit 32. When trying to connect to the partial removal slit 31, the label 23 may be broken as shown in FIG. 13.
Japanese Patent Laid-Open No. 9-48188 Japanese Patent No. 3773503

  The present invention has been completed based on the above circumstances, and provides a label sheet that can smoothly peel a part of a release sheet from a label without breaking a part of the label or sheet. The purpose is to do.

  As a means for achieving the above object, the invention of claim 1 is characterized in that a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer is laminated so that the pressure-sensitive adhesive contacts the release sheet, The label sheet is formed by arranging a plurality of slits for label separation for separating and sticking to a required place for use, and a plurality of regions surrounded by the slits for label separation are continuously formed on the release sheet A slit for removing the release sheet portion is formed from one edge of the release sheet to the other edge so as to be longitudinally cut, and by removing a part of the release sheet from the slit for removing the release sheet portion In the pressure-sensitive adhesive sheet, in the pressure-sensitive adhesive layer, a part of a region surrounded by the label separation slit can be exposed. Formed on the sheet in a region other than the region surrounded by the label separation slit, and perforated to connect the edge of the pressure-sensitive adhesive sheet and the label separation slit to overlap the release sheet portion removal slit And an auxiliary slit extending along the release sheet partial removal slit at least in a position intersecting with the label release slit in a region of the release sheet that is separated from the release sheet partial removal slit and removed. It is characterized by the formation.

  The invention of claim 2 is a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer that is stacked so that the pressure-sensitive adhesive contacts the release sheet, and a part of the pressure-sensitive adhesive sheet is cut off and pasted to a required location. A label sheet in which a plurality of label separating slits are formed side by side on the release sheet, from one end edge of the label separating slit to the edge opposite to the end edge of the label separating slit. A release sheet part removing slit is formed up to a position intersecting with the label separating slit in a close position, and by removing a part of the release sheet from the release sheet part removing slit, adhesion of the adhesive sheet In the adhesive layer, a part of the region surrounded by the label separating slit can be exposed. In the area other than the area surrounded by the label separation slit, a perforation is formed so as to continue to the release sheet part removal slit, and from the release sheet part removal slit of the release sheet It is characterized in that an auxiliary slit extending along the release sheet part removing slit is formed at least at a position intersecting with the label separating slit in the region to be separated and removed.

  Invention of Claim 3 is a sheet | seat for labels of Claim 2, Comprising: The said perforation formed in the said adhesive sheet and the said peeling sheet slip | deviates with respect to the extension line of the slit for said peeling sheet part removal. And is bent in the vicinity of the label separation slit and continues to the intersection of the label separation slit and the release sheet portion removal slit.

  According to the invention of claim 4, the pressure-sensitive adhesive sheet having the pressure-sensitive adhesive layer is laminated so that the pressure-sensitive adhesive contacts the release sheet, and the label is formed by forming slits for label separation vertically and horizontally on the pressure-sensitive adhesive sheet. A label sheet in which a region surrounded by a separation slit can be separated as a label, and the release sheet has a predetermined interval with respect to a longitudinally formed one of the label separation slits A separation sheet part removal slit is formed from one edge of the release sheet to the other edge so as to be separated from each other, and a part of the release sheet is removed from the release sheet part removal slit. The part of the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet that can be partially exposed by the label separation slit The release sheet portion removing slit has an inclined portion that approaches the longitudinal label separating slit in the vicinity of the one edge, and an intersection with the label separating slit at the tip of the inclined portion. Between the edge of the release sheet and the edge of the release sheet, and a breakable continuous portion is formed in which no slit is formed. Further, the present invention is characterized in that an auxiliary slit extending along the release sheet portion removing slit is formed at a position intersecting with at least one of the label separating slits formed in the lateral direction.

<Invention of Claim 1>
According to the invention of claim 1, when the label sheet is pulled so as to open the perforation by picking both sides sandwiching the perforation, the adhesive sheet and the release sheet are torn along the perforation, and the label separating slit Is cut open. When the label sheet is further pulled, a part of the release sheet is easily peeled off from the label (adhesive sheet) while being separated by the release sheet part removing slit, and only a part of the adhesive layer of the label is exposed.

  During this peeling operation, the release sheet may not be peeled off smoothly from the label, and it may be pulled with force to pull it off, or it may be different from the direction of the slit for removing the release sheet portion. If pulled in the direction, some labels and sheets may be torn. However, according to the label sheet of the present invention, an auxiliary slit is formed along the release sheet portion removal slit in the release sheet, thereby reducing the possibility that an unexpected place is torn. . The mechanism is not clear, but it is probably narrower from the release sheet partial removal slit to the auxiliary slit where peeling starts first than to peel off the entire width direction of the release sheet from the adhesive sheet at once. It is better to peel off the width, and then peel off from the auxiliary slit to the edge of the label with the force of peeling. Since it can be peeled off reliably, it is considered that tearing of labels and sheets can be prevented.

  In addition, the tear as described above is highly likely to occur at a position where the release sheet part removing slit and the label separating slit intersect, but in the present invention, the auxiliary slit is provided at the intersecting position. The possibility of tearing can be further reduced.

  Thus, according to the invention of claim 1, a part of the release sheet can be reliably peeled from the label (adhesive sheet) without breaking a part of the label or sheet.

<Invention of Claim 2 and Claim 3>
Also in the invention of claim 2, as in the invention of claim 1, the adhesive sheet and the release sheet are perforated by pulling the label sheet so as to open the perforation by pinching both sides of the perforation with fingers. And is cut up to the slit for separating the label. When the label sheet is further pulled, a part of the release sheet is easily peeled off from the label (adhesive sheet) while being separated by the release sheet part removing slit, and only a part of the adhesive layer of the label is exposed.

  Moreover, since the release sheet is formed with an auxiliary slit extending along the release sheet portion removal slit at a position intersecting with the label separation slit, it is possible to reduce the possibility that an unexpected place is torn. .

Furthermore, when the label sheet is arranged so that the adhesive sheet is in front and the perforation is located at the top, the perforation is provided on the left side of the extension line of the release sheet part removal slit. And is perforated by being bent in the vicinity of the label separating slit and continuing to the intersection of the label separating slit and the release sheet portion removing slit (invention of claim 3). Since the cutting direction of the sheet accompanying the cutting of the sheet can be gradually changed toward the release sheet removal portion side (to the release direction of the release sheet), the release operation of the release sheet is smoothly started. That is, when the tip of the cut portion reaches the label end, the load of the force applied to the label end is reduced, and the label can be more effectively prevented from being broken.

<Invention of Claim 4>
According to the invention of claim 4, when the label sheet is pulled so as to open the continuous part by grasping both sides of the continuous part with the finger, the continuous part is broken, and the inclination of the release sheet part removing slit is vigorously moved. The part is easily peeled off from the label (adhesive sheet) while the release sheet is separated by the part, and only a part of the adhesive layer of the label is exposed.

  And since the auxiliary slit extended along the peeling sheet part removal slit is formed in the peeling sheet in the position which crosses the slit for horizontal label separation, an unexpected place will be torn like the above-mentioned invention. The possibility can be reduced.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
<First Embodiment>
A first embodiment of the present invention will be described with reference to FIGS.

First, the configuration of the label sheet 10 will be described.
For example, a pressure-sensitive adhesive is applied over the entire surface of a rectangular pressure-sensitive adhesive sheet 20 having an A4 size to form a pressure-sensitive adhesive layer 21. An A4 size release sheet 30 is overlaid on the pressure-sensitive adhesive sheet 20 so as to cover the entire area of the pressure-sensitive adhesive layer 21, and the two sheets are integrated to form a single label sheet 10.

  The adhesive sheet 20 is provided with a plurality of label separation slits 22 having a substantially rectangular shape and arranged in two rows along the long side of the adhesive sheet 20. A plurality of labels 23 are formed so as to be separable from the adhesive sheet 20 surrounded by the label separation slits 22.

  The release sheet 30 is formed with a release sheet portion removing slit 31 extending from one short side edge to the other short side edge and parallel to the long side. A total of two slits 31 for removal are formed one above the other so as to continuously cut each region surrounded by the slits 22 for separating the labels. As shown in FIG. 1, the release sheet portion removing slit 31 is provided so as to cut, for example, a position near the right end of the region surrounded by the substantially rectangular label separating slit 22.

  A perforation 11 is formed at a position overlapping the release sheet portion removing slit 31 in an area other than the area surrounded by the label separating slit 22 of the adhesive sheet 20.

  Further, among the release sheet 30, between the label separating slit 22 formed along the long side direction of the label sheet 10 and the release sheet part removing slit 31, these slits 22, 31 are provided. An auxiliary slit 33 is formed to extend in parallel and intermittently. The auxiliary slit 33 has the same length, etc. at the position intersecting with the label separating slit 22 formed along the short side direction of the label sheet 10 and at the center position of the short side length of the label 23. It forms so that it may become a space | interval.

Next, the operation and effect of the label sheet 10 of the present embodiment will be described.
When the left and right sides of the perforation 11 formed on one short side of the pressure-sensitive adhesive sheet 20 and the release sheet 30 are picked with fingers and pulled so as to open the perforation 11, the pressure-sensitive adhesive sheet 20 and the release sheet 30 are moved to the perforation 11. It is guided and cut, and is cut to the intersection with the label separating slit 22. As it is, the release sheet 30 is pulled along the release sheet portion removal slit 31 in the direction of peeling off the adhesive sheet 20, but at this time, the release sheet portion removal slit 31 was caught for a moment without being smoothly separated. It may become such a state. However, in such a case, in the label sheet 10 of the present embodiment, first, a part of the release sheet 30 from the release sheet part removing slit 31 to the auxiliary slit 33 is peeled off from the adhesive sheet 20 with a small force. Thus, once peeling is started, the remaining portion can be easily peeled off, and thereafter, the auxiliary slit 33 to the label separating slit 22 are peeled off (see FIG. 3).

  In this way, when a part of the release sheet is peeled off from the adhesive sheet along the release sheet portion removal slit, the release sheet portion of the plurality of labels 23 formed in a line on the label sheet 10 is obtained. The release sheet 30 can be peeled off along the removal slit 31. As a result, all of these labels 23 are in a state where a part of the pressure-sensitive adhesive layer 21 is exposed while adhering to the release sheet 30 (see FIG. 4).

  When these labels 23 are affixed to, for example, an envelope or the like, the exposed pressure-sensitive adhesive layer 21 while holding the part where the release sheet 30 remains among the labels 23 from which a part of the pressure-sensitive adhesive layer 21 is exposed. Is pasted to the required location. Then, while separating the label 23 from the adhesive sheet 20 along the label separating slit 22, the remaining part of the release sheet 30 is peeled from the label 23, the adhesive layer 21 is exposed, and the label 23 is attached to a required location. By repeating the same operation as described above for the plurality of labels 23, the labels 23 can be continuously attached.

  As described above, in the present embodiment, by providing the auxiliary slit 33, even if the release sheet cannot be smoothly peeled off, the release sheet 30 can be reliably removed without breaking the label 23 or a part of the label sheet 10. Part can be peeled from the pressure-sensitive adhesive sheet 20.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIGS.
The difference from the first embodiment is that the release sheet part removing slit 31 is provided from the lower end edge in FIG. 1 of the release sheet 30 to the position intersecting with the label separating slit 22 located closest to the upper end edge. From the edge of the short side of the pressure sensitive adhesive sheet 20 and the release sheet 30 on the left side in the figure from the extension line of the release sheet part removal slit 31 and the extension line of the release sheet part removal slit 31 and the release sheet part removal slit 31 The perforation 11 is formed at the intersection with the. The perforation 11 is formed so as to be connected to the label separation slit 22 while being bent in the vicinity of the label separation slit 22 (see FIG. 5).

  Since the other parts are the same as those in the first embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

The operation and effect of the second embodiment will be described.
When the left and right sides of the perforation 11 formed on one short side of the pressure-sensitive adhesive sheet 20 and the release sheet 30 are picked with fingers and pulled so as to open the perforation 11, the pressure-sensitive adhesive sheet 20 and the release sheet 30 are moved to the perforation 11. Guided and cut. At this time, since the perforation 11 is formed to be connected to the label separation slit 22 while being bent in a curved manner, the cutting direction of the label sheet 10 associated with the cutting of the perforation 11 is changed to the release sheet 30 as the adhesive sheet. It can be gradually changed from the direction 20 to the direction of peeling, whereby the part removing operation of the release sheet 30 is started smoothly.

  Moreover, since an auxiliary slit 33 extending along the release sheet portion removal slit 31 is formed in the release sheet 30 at a position intersecting with the label separation slit 22, an unexpected place is torn like the above embodiment. It is possible to reduce the possibility of being lost.

  Since other operations and effects are the same as those in the first embodiment, a duplicate description is omitted.

<Third Embodiment>
Next, a third embodiment of the present invention will be described with reference to FIGS.
The label sheet 10 of the present embodiment is configured by forming a label 23 by forming label separating slits 22 in the vertical and horizontal directions of the pressure-sensitive adhesive sheet 20. Unlike the above-described embodiment, the label sheet 10 is formed on the peripheral edge of the label sheet 10. No blank area other than the label 23 is provided. In the release sheet 30, a release sheet portion removal slit 31 extending along the long side direction of the label sheet 10 extends vertically from one end edge to the other end at a position on the right side of the label 23 in the drawing. Is formed. Among them, the vicinity of one edge (upper part in the drawing) of the release sheet part removing slit 31 on the central part side of the sheet 10 is an inclined part 34 toward the label separating slit 22 extending vertically (up and down). The upper end of the inclined portion 34 reaches a position that intersects with the vertical label separating slit 22. And between the intersection and the upper end edge of the peeling sheet 30, it is set as the breakable continuous part 35 in which no slit is formed.
Further, an auxiliary slit 33 extending in the direction along the release sheet part removing slit 31 is located at a position intersecting with the label separating slit 22 extending laterally (left and right) on the right side of the release sheet part removing slit 31 in the drawing. Is formed.

Next, the operation and effect of the label sheet 10 of the present embodiment will be described.
When using the labels 23 in the right column in the figure, a part of the release sheet 30 is peeled off from the upper right position of the label sheet 10 downward by the release sheet partial removal slit 31, and the adhesive of the adhesive sheet 20 is removed. By exposing a part of the agent layer 21, the label 23 can be easily peeled off from the release sheet 30. Further, when using the label 23 in the left column in the drawing, if the label separating slit 22 extending in the long side direction of the label sheet 10 is grasped with both fingers and pulled to open the label separating slit 22.
