Description

  The present invention relates to a labeled container cap to which a security label that proves the opening history of the container cap is attached, and a security label.

  In recent years, containers having a so-called tamper evidence function for proving the opening history have been adopted in a wide range of beverage containers and the like in order to prevent the containers from being tampered with in the distribution process.

  As a container having such a tamper-evident function, a container cap and a container mouth tube part are collectively covered with a shrink label (see, for example, Patent Document 1), or an opening formed on an upper lid of a container cap Known is one in which a skirt wall of a cap body is provided with a TE (tamper evidence) cover so as to cover the collar (see, for example, Patent Document 2).

  However, when such a shrink label or TE cover is provided, it is possible to recognize the opening history at a glance from the appearance, but in order to attach the shrink label, it is necessary to install dedicated equipment and the equipment. Installation space is required, and the TE cover has a problem that its opening method is difficult to understand, and a problem that it is difficult to convey and chuck.

  Therefore, as one method for avoiding the above problem, it is known to attach a security label that can prove the opening history of the container cap to the container cap. As such a security label, when the security label is peeled off from an adherend such as a container, a part of the printed layer and the adhesive layer remain on the adherend side, and the security label is peeled off from both the security label and the adherend. Those that leave traces are widespread. Such a security label is generally called a transfer type.

  However, when such a security label is used, there is a risk that the adhesive residue remaining on the adherend side may be mixed in the container, and in particular for use in containers such as beverages, foods, pharmaceuticals, and cosmetics. There is a problem that it is not suitable, and there is also a problem that the residual piece adhered to the container side impairs the appearance of the container, and the adhesiveness of the residual piece causes dust or the like to adhere.

  Therefore, a security label (tamper-proof label) described in Patent Document 3 has been proposed as a security label capable of recognizing that the security label has been peeled off but avoiding the adhesive remaining on the adherend. .

  As shown in FIG. 7, the security label 130 described in Patent Document 3 includes a transparent surface film layer 141, a release layer 142 formed in a predetermined pattern on the back surface of the surface film layer 141, a surface film layer 141, and The printed layer 143 formed to cover the back surface of the release layer 142, the cushion layer 144 formed on the back surface of the printed layer 143, and the adhesive layer 145 formed on the back surface of the cushion layer 144 are overlapped in the label layer direction. Have a structure.

  In the security label 130 described in Patent Document 3, as shown in FIG. 7, when the security label 130 is peeled off from the adherend 120 such as a container, the release layer 142 is peeled off from the surface film layer 141. The printed layer 143 </ b> B formed on the back surface of 142 is lifted off from the printed layer 143 </ b> A formed on the back surface of the front film layer 141, and a gap S is formed between the front film layer 141 and the release layer 142. By forming the gap S, the printed layer 143B provided with the release layer 142 becomes translucent, and a predetermined pattern such as characters visible from the outside is displayed on the security label 130. Such a security label is generally called a non-transfer type.

  As described above, in the security label 130 described in Patent Document 3, a force in the label layer direction (label front and back direction), that is, a force for peeling the peeling layer 142 from the surface film layer 141 is applied to the security label 130. In addition, a predetermined pattern such as a character is displayed on the security label 130.

  However, in such a container cap with a label, as shown in an example in FIG. 8, there is a usage mode in which the top cover 122 is forcibly opened with the security label 130 still attached to the container cap 120. In this case, the security label 130 is torn in the label plane direction near the center. In such a case, since no force in the direction of the label layer acts on the security label 130, a predetermined pattern such as characters is not displayed on the security label 130 even though the container cap 120 is opened. There was a problem that it would be.

  Therefore, the present invention solves these problems, and provides a container cap with a label and a security label that can display a predetermined pattern such as characters on the security label with a simple configuration when the container cap is opened. It is intended to do.

The container cap with a label according to the present invention is a container cap with a label including a container cap and a security label attached to an outer surface of the container cap, and the security label is a label adhesive that adheres to the container cap. The label adhesive part is formed to cover the surface film layer, the release layer formed in a predetermined pattern on the back surface of the surface film layer, and the back surface of the surface film layer and the release layer It has a structure in which a printed layer and an adhesive cushion layer formed on the back surface of the printed layer are overlapped in the label layer direction, the label adhesive portion includes a break initiation weakening line extending along a label plane, and the break An induction weakening line extending along the label plane so as to form an angle with respect to the breakage starting weakening line from one end of the starting weakening line; More solves the above problems.
The security label of the present invention is a security label that is affixed to the outer surface of the container cap and proves the opening history of the container cap, and the security label has a label adhesive portion that adheres to the container cap, The label adhesive portion includes a surface film layer, a release layer formed in a predetermined pattern on the back surface of the surface film layer, a print layer formed so as to cover the back surface of the surface film layer and the release layer, It has a structure in which an adhesive cushion layer formed on the back surface of the printed layer is overlapped in the label layer direction, and the label adhesive portion has a break start weakening line extending along the label plane and one end of the break start weakening line. And the induction weakening line extending along the label plane so as to form an angle with respect to the breaking start weakening line. It is intended to attain.

  According to the inventions according to claims 1 and 8, the label adhesive portion of the security label includes the surface film layer, the release layer formed in a predetermined pattern on the back surface of the surface film layer, and the back surfaces of the surface film layer and the release layer. When the security label is peeled off, the surface film layer has a structure in which the printed layer formed so as to cover the adhesive layer and the adhesive cushion layer formed on the back surface of the printed layer are stacked in the label layer direction. The release layer is peeled off, and a gap is formed between the surface film layer and the release layer. By forming this gap, a predetermined pattern such as letters is displayed on the security label, and thus the adhesive remains on the container cap. Without being able to prove the opening history of the container cap, the following effects can be achieved.

  That is, according to the inventions according to claims 1 and 8, in addition to the break start weakening line that is the starting point of the break start, the induction weakening line that extends in the label plane direction so as to form an angle with respect to the break start weakening line. Even if the security label is torn in the direction of the label plane, such as when the container cap is forcibly opened while the security label is still attached to the container cap, When the breakage of the security label starting from the point of origin is induced by an induction weakening line extending at an angle to the breakage start weakening line, a force in the direction of the label layer acts on the security label. The peeling layer can be peeled from the layer, and a predetermined pattern such as letters can be reliably displayed on the security label.

Further, according to the invention according to claim 2, the break initiation weakening line extends from one end connected to the induction weakening line toward the label non-adhesive portion side, in other words, in the direction of peeling the security label. By extending along the line, it is possible to prevent the security label from being broken at the breaking start weakening line when the user grasps the label non-adhesive portion and peels off the security label.
Moreover, according to the invention which concerns on this 3rd, 4th, the break start weakening line is arrange | positioned in parallel with the boundary line between a cap main body and an upper cover, Therefore A security label is still affixed. When the upper lid is forcibly opened in the state, it is possible to suppress the breakage of the security label from a place other than the break start weakening line.
Further, according to the invention according to claim 5, when the upper cover is opened, the guide weakening line extends from the end part of the breaking start weakening line located on the knob side of the upper cover. By placing a guide weakening line on the side of the knob that increases the distance between the container cap and the container cap, if you try to force open the top lid with the security label still attached, the guide weakening line is securely By rupturing, a force in the direction of the label layer can be applied to the security label.
According to the invention of claim 6, the security label is disposed so as to straddle the position displaced by 90 ° from the hinge portion in the circumferential direction of the container cap, so that the security label remains attached. When the upper lid is forcibly opened in this state, the induction weakening line can be reliably broken.
According to the invention of claim 7, the angle between the break start weakening line and the induction weakening line is set to 90 ° or more, so that the security label started from the break start weakening line Can be reliably induced to the induction weakening line.

  Below, the container cap 10 with a label which concerns on one Embodiment of this invention is demonstrated based on drawing.

  As shown in FIG. 1, the labeled container cap 10 includes a container cap 20 configured as a synthetic resin hinged cap attached to a container mouth tube portion of a container (not shown), and a side portion of the container cap 20. It is comprised from the security label 30 affixed on the outer surface.

As shown in FIG. 1, the container cap 20 includes a cap body 21 attached to the container mouth tube portion and an upper lid 22 attached to the cap body 21.
The cap body 21 and the upper lid 22 are connected by a hinge portion 23, and the upper lid 22 is formed at a position shifted from the hinge portion 23 in the circumferential direction of the container cap 20 (180 ° in this embodiment). A portion 24 is formed.

  As shown in FIG. 1, the security label 30 is affixed across the boundary line B between the cap body 21 and the upper lid 22 and is adhered to the container cap 20 as shown in FIGS. 1 and 3. It has an adhesive part 40 and a label non-adhesive part 50 that is formed adjacent to the label adhesive part 40 in the label plane direction and is not adhered to the container cap 20.

As shown in FIG. 1, the security label 30 is arranged such that the boundary line between the label adhesive part 40 and the label non-adhesive part 50 is orthogonal to the boundary line B between the cap body 21 and the upper lid 22. The label adhesive part 40 is arranged on the knob part 24 side, and the label non-adhesive part 50 is arranged on the hinge part 23 side.
The security label 30 is disposed in the circumferential direction of the container cap 20 so as to straddle a position shifted by 90 ° from the hinge portion 23 (more precisely, the center of the hinge portion 23 in the circumferential direction).

  As shown in FIG. 3, the label adhesive part 40 covers the surface film layer 41, the peeling layer 42 formed in a predetermined pattern on the back surface of the surface film layer 41, and the back surfaces of the surface film layer 41 and the peeling layer 42. And the adhesive cushion layer 44 formed on the back surface of the print layer 43 are stacked in the label layer direction.

  Moreover, the label non-adhesion part 50 has the structure which accumulated the surface film layer 51 and the printing layer 53 formed so that the back surface of the surface film layer 51 might be covered in the label layer direction, as shown in FIG. ing.

  As shown in FIG. 3, the surface film layer 41 of the label adhesive part 40 and the surface film layer 51 of the label non-adhesive part 50 are continuous in the label plane direction, and the printing layer 43 of the label adhesive part 40 and the label non-adhesive part The print layer 53 of the adhesive portion 50 is continuous in the label plane direction.

The surface film layers 41 and 51 are formed of a transparent polymer film such as vinyl, polypropylene, or polystyrene.
The release layer 42 has releasability, UV (ultraviolet curable) silicon resin, silicon-based, Teflon (registered trademark) -based, matte particle-based, fat and oil-based typified by acrylic ester of higher alcohol such as stearyl acrylate, It is formed from a cellulose ester represented by nitrocellulose, an ether type or the like. The release layer 42 has a predetermined pattern such as “opened”, and is formed by a plurality of relief printing, flexographic printing, screen printing, and the like at predetermined intervals.
The print layers 43 and 53 are printed when the security label 30 is peeled off.
The adhesive cushion layer 44 has cushioning properties, film properties, and adhesiveness, and has a characteristic of irreversibly elastically changing.

  As shown in FIG. 1 and FIG. 2, the label adhesive portion 40 has a break start weakening line 60 extending along the label plane and an angle from one end of the break start weakening line 60 to the break start weakening line 60 (this embodiment). An induced weakening line 70 is formed that extends along the label plane to form an angle of about 150 °.

  In the present embodiment, the break initiation weakening line 60 and the induction weakening line 70 are configured by a plurality of slits that are intermittently continuous in the label plane direction. Need only be easier to break than the peripheral portion other than the break initiation weakening line 60 and the induction weakening line 70. For example, it is thinner than the peripheral portion, so that it is easy to break. Good.

As shown in FIG. 1 and FIG. 2, the break start weakening line 60 is positioned parallel to the boundary line B between the cap body 21 and the upper lid 22, more specifically, located on the boundary line B. Furthermore, it extends toward the label non-adhesive part 50 side from one end (the knob side end part 62) connected to the induction weakening line 70.
Further, as shown in FIG. 2, the breaking start weakening line 60 is formed on the hinge side end 61 located on the hinge part 23 side (label non-adhesive part 50 side) and the knob part 24 side (label adhesive part 40 side). It has a knob side end 62 located.
The induction weakening line 70 extends from the knob side end portion 62 of the fracture start weakening line 60.

  Next, in the container cap 10 with a label of this embodiment, the state of each part when the security label 30 is peeled from the container cap 20 will be described with reference to FIG.

  First, when the user grasps the label non-adhesive portion 50 and peels off the security label 30, the security label 30 is bent so that the label non-adhesive portion 50 side is lifted from the surface of the container cap 20, as shown in FIG.

  At this time, due to the security label 30 being bent, as shown in FIG. 4, the release layer 42 is peeled from the surface film layer 41, and the printed layer 43 </ b> B formed on the back surface of the release layer 42 is the surface. The printed layer 43 </ b> A formed on the back surface of the film layer 41 is lifted off (cut), and a gap S is formed between the surface film layer 41 and the release layer 42.

  At this time, the peeled release layer 42 and the printed layer 43B bite into the adhesive cushion layer 44 due to the film property and cushioning property of the adhesive cushion layer 44, and the irreversible elastic deformation of the adhesive cushion layer 44 causes the release layer 42 and The state in which the printing layer 43 </ b> B bites into the adhesive cushion layer 44 is maintained.

  Then, by forming a gap S between the surface film layer 41 and the release layer 42, the printed layer 43B provided with the release layer 42 becomes translucent, and is visible from the outside (the surface film layer 41 side). A predetermined pattern such as “” is displayed on the security label 30. The security label 30 of this embodiment is a so-called non-transfer type.

  Next, in the container cap 10 with a label of the present embodiment, the state of each part when the upper lid 22 is forcibly opened with the security label 30 still attached to the container cap 20 is shown in FIG. explain.

  First, when the top lid 22 is forcibly opened with the security label 30 still attached to the container cap 20, the security label 30 starts to break from the break start weakening line 60. The break starting weakening line 60 extends from the hinge side end 61 to the hinge part 23 side, and is guided by the induction weakening line 70 from the knob side end 62 of the breaking start weakening line 60 to the knob part 24 side. .

Since the induction weakening line 70 extends at an angle with respect to the breaking start weakening line 60, when the breakage of the security label 30 is guided by the induction weakening line 70, the security label 30 is directed to the label layer direction. Force, that is, a force for peeling the peeling layer 42 from the surface film layer 41 is generated, and as a result, a predetermined pattern such as characters is displayed on the security label 30.
At this time, the induction weakening line 70 is broken inside because the induction weakening line 70 is formed on the inner side of the outer edge of the label adhesive part 40 (in other words, it does not reach the outer edge of the label adhesive part 40). Sometimes, the surface film layer 41 is pulled more (i.e., the region between the outer edge of the label adhesive portion 40 and the end of the induction weakening line 70 on the breaking start weakening line 60 side is caused by the turning of the upper lid 22 when the cap is opened). Therefore, the force in the direction of the label layer is more likely to act on the security label 30 and the above-described effects are further promoted.

  Note that the specific modes of the fracture start weakening line 60 and the induction weakening line 70 are not limited to the example shown in FIG. 2, and various design changes can be made.

For example, the angle between the break start weakening line 60 and the induction weakening line 70 may be any, and the angle between the break start weakening line 60 and the induction weakening line 70 is 90 ° as in the modification shown in FIG. You may set so that it becomes. It should be noted that setting the angle between the break start weakening line 60 and the induction weakening line 70 to be 90 ° or more indicates that the break of the security label 30 started from the break start weakening line 60 is the induction weakening line 70. It is preferable because it can be guided smoothly.
In the example shown in FIG. 2, one induction weakening line 70 extends from one end of the break initiation weakening line 60. However, as in the modification shown in FIG. 6, the break initiation weakening line 60 and the induction weakening line 70. A plurality of (two) induction weakening lines 70 may extend from one end of the fracture start weakening line 60 so as to form a T shape.
In the example shown in FIG. 2, the induction weakening line 70 is described as extending from the knob-side end 62 of the breaking start weakening line 60, but conversely, from the hinge side end 61 of the breaking start weakening line 60. The induction weakening line 70 may extend.
In the example shown in FIG. 2, the break start weakening line 60 and the induction weakening line 70 are formed on the inner side of the outer edge of the label adhesive portion 40, but at least one of the break start weakening line 60 or the induction weakening line 70 is present. However, the outer edge of the label adhesive part 40 may be reached. From the viewpoint of preventing unexpected breakage of the security label 30, it is preferable that the break start weakening line 60 and the induction weakening line 70 are formed inside the outer edge of the label adhesive portion 40.
Further, at least one of the break initiation weakening line 60 or the induction weakening line 70 may extend to the inside of the label non-adhesive portion 50.
In the example shown in FIG. 2, the break start weakening line 60 is described as being disposed on the boundary line B. However, the position of the break start weakening line 60 may be shifted from the boundary line B, The fracture start weakening line 60 may be arranged non-parallel to the boundary line B.
In the example shown in FIG. 2, both the break start weakening line 60 and the induction weakening line 70 are formed in a straight line, but at least one of the break start weakening line 60 and the induction weakening line 70 is in a curved line shape. It may be formed.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment, A various design change can be performed without deviating from this invention described in the claim. Is possible.

For example, in the above-described embodiment, the security label is described as being pasted across the boundary line between the cap body and the upper lid. However, the position where the security label is pasted is not limited to this, for example, a container It may be affixed across the boundary line between the container cap and the container cap. In this case, the container cap may be configured as a single part that is not separated into the cap body and the upper lid.
In the above-described embodiment, the security label has been described as having a label adhesive portion that is adhered to the container cap and a label non-adhesive portion that is not adhered to the container cap. In other words, the entire security label may be configured as a label adhesive portion.
Moreover, in embodiment mentioned above, although demonstrated as what forms an adhesive cushion layer by 1 layer structure, the specific aspect of an adhesive cushion layer is not limited to this, For example, like the prior art example shown in FIG. Even if the adhesive cushion layer is constituted by a two-layer structure of a cushion layer formed on the back surface of the printed layer and having cushioning properties and film properties, and an adhesive layer formed on the back surface of the cushion layer and having adhesive properties. Good.
In the above-described embodiment, the cap main body and the upper lid have been described as being connected by the hinge portion. However, the specific aspect of the container cap is not limited thereto, and for example, the cap main body and the upper lid are screwed. It may be connected with.
