Description

  The present invention relates to a sealing tack label for sealing a product outlet.

Conventionally, various products such as tissue paper, wet sheets, foods such as confectionery, cosmetics, and medicines are stored and packaged in various packaging materials such as containers and bags.
Among these packaging materials, packaging materials in which a take-out port for taking out a stored product is formed are also widely used.
Such a packaging material is mainly used for storing a product that requires sealing, such as a wet sheet. The packaging material includes a bag body capable of sealingly storing a plurality of wet sheets, and a take-out port for taking out the stored wet sheet is formed in a part of the bag body. The take-out port is usually constituted by a cut line or the like obtained by cutting a part of the bag body. In order to seal the take-out port, a re-sticking tack label (hereinafter sometimes simply referred to as “tack label”) is stuck on the surface of the bag body.
In this tack label, an adhesive is provided on the back surface of the label base material corresponding to the range covering the take-out port, and the end of the label base material is used as a gripping piece so that the end of the label base material is not adhered. It is an area.
Then, the end of the label base material is picked, the sealing tack label is peeled off from the packaging material, the desired wet sheet is taken out from the takeout port, and then the tacking label is reapplied, whereby the packaging material is again Sealed.

However, as described above, since the tack label for sealing can be re-applied after being peeled off, for example, for the purpose of mischief, the tack label is peeled off and the wet sheet is extracted, and then the original state is restored. May be re-applied to Moreover, after peeling off a tack label and mixing in a foreign material from an extraction port, it may be reapplied as it is.
In view of such a problem, conventionally, a measure for attaching a break label separately to a sealing tack label has been taken. Specifically, in this break label, an adhesive is coated on the back surface of a base material (for example, a relatively thin paper base material) that is easily broken by applying a shearing force. For example, as shown in FIG. 7, the broken label 10 is stuck so as to straddle the surface of the sealing piece portion 111 of the sealing tack label 11 and the surface of the packaging material 12. Then, when the sealing tack label 11 is peeled off, the broken label 10 is divided. For this reason, it can be easily recognized that it has once peeled off.
However, in the above means, a break label must be attached separately. Therefore, the manufacturing cost of the broken label itself and the cost for attaching the broken label are required, and there is a problem that the product cost is significantly increased.

  Then, this invention makes it a subject to provide the tack label for sealing which can understand easily that it once peeled, without using a separate label.

The present inventor has conducted intensive research in view of the above problems, and by taking the following measures, it is possible to easily determine whether or not it has been peeled once while suppressing an increase in product cost. Developed a label.
That is, the present invention is a tuck label for sealing that is pasted to seal the take-out port of a packaging material in which a take-out port for taking out stored goods is formed, and at least within a range surrounding the take-out port. For sealing that has an adhesive area that is attached to the surface of the packaging material and that can be re-applied after peeling, and a non-adhesive area is provided on the back of the end of the label base. In the tack label, an adhesive region to be attached to the surface of the packaging material is provided between the adhesive region and the non-adhesive region, and the adhesive region provides a sealing tack label that cannot be re-applied after peeling. .

The sealing tack label is used by sticking the adhesive region on the surface of the packaging material and covering the adhesive region on the surface of the packaging material so as to cover the outlet of the packaging material.
By picking the non-adhesive region of the tack label by hand and peeling it off, the take-out port of the packaging material is opened, and the stored product can be taken out therefrom.
After the product is taken out, the take-out port can be sealed again by reattaching the adhesive area of the tack label to the packaging material.
Since the tack label for sealing of the present invention has an adhesive region that cannot be re-applied after peeling between the adhesive region and the non-adhesive region, the adhesive region adheres to the packaging material when the tack label is re-applied. Without this, the adhesion region is lifted from the packaging material. Accordingly, it can be easily determined that the tack label has been peeled once.

In a preferred aspect of the present invention, the sealing tack label is provided in which an embossed or ruled line is formed on the label base material in the adhesive region.
By providing the emboss or ruled line in this way, the label base material is likely to warp in the adhesion region. For this reason, once the tack label is peeled from the packaging material, the label base material is curved in the adhesion region. Therefore, it becomes easier to determine that the tack label has been peeled once.

Furthermore, in a preferred embodiment of the present invention, there is provided the sealing tack label described above, wherein the adhesive region is composed of a heat-sensitive adhesive having a softening point (ring ball method) of 80 to 130 ° C.
By using the heat-sensitive adhesive having the softening point, the heat-sensitive adhesive does not exhibit tackiness under normal use conditions of the tack label. For this reason, after peeling a tack label once, there exists no possibility that an adhesion | attachment area | region will adhere to a packaging material, and there exists the said effect reliably.

  When the tack label for sealing according to the present invention is reapplied after peeling, the adhesive region is in a state of floating from the packaging material. Since a part of the tack label is peeled off from the packaging material in this way, it can be easily determined that the tack label has been peeled once.

Hereinafter, the present invention will be specifically described with reference to the drawings.
1 and 2, reference numeral 1 denotes a packaging material 3 in which a take-out port 2 for taking out a stored product is formed, and a sealing tack label 5 for sealing the take-out port 2 of the packaging material 3. The package provided is shown.
The packaging material 3 is not particularly limited as long as it can store products, and various types can be used.
For example, the packaging material 3 is formed by forming a flexible sheet in a sealed bag shape. Specifically, the packaging material 3 includes a bag main body 31 having a storage portion for storing a product therein, and an outlet 2 formed in the bag main body 31. The take-out port 2 is formed at a position communicating with the storage portion of the bag body 31.
The bag body 31 is formed in a bag shape by, for example, a three-sided bonding method. That is, the bag main body 31 is composed of a single sheet body, and wraps the product, overlaps both end portions of the sheet body into a cylindrical shape, and bonds the overlapping portion (for example, heat seal). In order to seal both open ends, both open ends are bonded together to form a sealed bag.
Moreover, the bag main body 31 can also be formed from two sheet bodies. In this case, the sealed bag-shaped bag body 31 is formed by adhering the peripheral end portions of the two sheet bodies in a state where the product is interposed between the two sheet bodies.

The take-out port 2 is formed at a predetermined position of the bag body 31, for example, on the upper surface of the bag body 31. The take-out port 2 is formed in a region surrounded by a broken line 21 obtained by cutting a part of the bag body (sheet body) into a linear shape. That is, when the tack label 5 is peeled off, a part of the bag body 31 surrounded by the breaking line 21 is cut off, and the takeout port 2 is formed in the cutout portion.
However, the take-out port 2 is not limited to the one formed by cutting along the breaking line 21. For example, a part of the bag main body 31 is opened in a predetermined shape in advance (for example, an oval opening), and the take-out port 2 can be used as the take-out port. Good. Furthermore, the taking-out port 2 can also be comprised by the linear cut line formed in a part of bag main body, for example.

The sheet body constituting the bag body 31 is not particularly limited, and a synthetic resin sheet (synthetic resin film is also synonymous), a laminated sheet of different types or the same type of synthetic resin, and a laminated layer of a synthetic resin and a metal foil such as an aluminum foil. Sheets (including metal-deposited synthetic resin sheets), laminated sheets of synthetic resin and paper, and other various laminated sheets can be used. It is preferable to use a synthetic resin sheet or a laminated sheet to which a gas barrier property, a light shielding property, etc. are imparted according to the type of product to be stored. The sheet body preferably has a sealant layer so that it can be heat-sealed when formed into a bag shape. The thickness of the sheet is usually about 50 to 300 μm.
The packaging material 3 is not limited to a flexible sheet material formed in a bag shape. For example, an assembly box of paper or a synthetic resin sheet, a synthetic resin molded container, a glass container, a metal container, or the like can be used. It can also be used. Moreover, it is preferable that the packaging material 3 is configured so that the product can be sealed and stored, but depending on the product to be stored, the sealing performance may not be strictly required.

The product stored in the packaging material 3 is not particularly limited, and examples thereof include wet sheets, tissue paper, foods such as confectionery, cosmetics, and medicines.
Since the outlet 3 is sealed with the sealing label 5, the packaging material 3 is particularly effective for storing products that require sealing properties, such as wet sheets, foods, and medicines.
The wet sheet is obtained by impregnating various sheets such as nonwoven fabric, woven fabric, and paper with liquid components and solid components such as water, alcohol, disinfectant, chemicals, and fragrances.

Next, the sealing tack label 5 which is a characteristic part of the present invention will be described in detail.
The tuck label 5 for sealing is a label base material on which a sealing piece portion 61 capable of covering the take-out port 2 and its peripheral portion and a knob piece portion 62 extending from one side 61a of the sealing piece portion 61 are formed. 6, an adhesive region 7, an adhesive region 8, and a non-adhesive region 9 are provided on the label substrate 6.
The sealing piece portion 61 is formed, for example, in a substantially rectangular shape in plan view, and the knob piece portion 62 is formed, for example, in a semicircular shape in plan view. But the sealing piece part 61 and the knob piece part 62 are not limited to these shapes, It can deform | transform into a suitable shape. Further, the size of the sealing piece portion 61 is appropriately designed according to the size of the take-out port 2, and the size of the knob piece portion 62 is designed to be a size that can be picked by a finger.
In addition, in the surface of the sealing piece portion 61, a substantially U-shaped cut line 63 in plan view is formed. This cut line 63 penetrates the sealing piece 61 and is formed in the vicinity of both corners on the other side facing the one side 61a. The cut line 63 functions as a peeling stopper that prevents the tack label 5 from being completely peeled off from the packaging material 3 when the tack label 5 is peeled off.
The material of the label substrate 6 is not particularly limited. For example, a synthetic resin sheet (synthetic resin film is also synonymous) such as a biaxially stretched polyethylene terephthalate sheet or a biaxially stretched polypropylene sheet, a different type or the same type of synthetic resin. A laminated sheet, a laminated sheet of metal foil such as synthetic resin and aluminum foil (including a metal vapor-deposited synthetic resin sheet), a laminated sheet of synthetic resin and paper, and other various laminated sheets can be used. Since the label base material 6 tends to be warped due to the properties of the base material itself, for example, a synthetic resin sheet containing a vinyl chloride resin or an amide resin, and a laminated sheet in which sheets of the material are laminated are used. It is preferable. In addition, when a laminated sheet is used as the label substrate 6, warpage is likely to occur due to the nature of the substrate itself, so that either one of the upper and lower layers constituting the laminated sheet has a room temperature or higher than the other layer. It is preferable to use a material that shrinks greatly depending on the room humidity (upper and lower layers having different shrinkage rates). By using the label base material 6 that can cause such warpage, the adhesive region of the tack label 5 is likely to be curved after the tack label 5 is peeled off. It becomes easy to distinguish.
In addition, it is preferable to use the sheet | seat to which gas barrier property, light-shielding property, etc. were provided for the label base material 6 according to the kind of goods to accommodate.
The thickness of the label substrate 6 is usually about 50 to 300 μm.

An adhesive region 7 and an adhesive region 8 are provided on the back surface of the sealing piece portion 61 of the label base material 6, and a non-adhesive region 9 is provided on the back surface of the knob piece portion 62 of the label base material 6.
The adhesive region 7 is provided at least in the region surrounding the opening edge portion that constitutes the take-out port 2 on the back surface of the sealing piece portion 61.
The adhesion region 8 is provided between the adhesion region 7 and the non-adhesion region 9 on the back surface of the sealing piece portion 61. The adhesion region 8 is provided in a strip shape parallel to one side 61a side (side where the knob piece portion extends) of the sealing piece portion 61. The width W (see FIG. 3) of the adhesion region 8 is not particularly limited, but if it is too short, there is no significance of providing the adhesion region 8, and therefore it is usually 5 mm or more, preferably 10 mm or more. On the other hand, the longer the width W of the bonding region 8 is, the easier it is to visually recognize that it is peeled off. However, if it is too long, a material loss occurs, so it is usually 30 mm or less, preferably 20 mm or less.
The adhesive region 7 is affixed to the surface of the packaging material 3 and can be reapplied after peeling. The adhesion region 8 is affixed to the surface of the packaging material 3 and cannot be reapplied after peeling. The non-adhesion region 9 cannot be attached to the surface of the packaging material 3. The adhesive region 7 is configured by exposing the adhesive applied to the label base 6, and the adhesive region 8 is configured by exposing the adhesive applied to the label base 6. .

Specifically, as shown in FIG. 3, an adhesive layer 71 coated with an adhesive is formed on the entire back surface of the label substrate 6. The pressure-sensitive adhesive is not particularly limited as long as it can be attached to the surface of the packaging material 3 and can be peeled off by hand after sticking and can be re-sticked after peeling. As the pressure-sensitive adhesive, a pressure-sensitive adhesive widely used for tack labels, for example, a known pressure-sensitive pressure-sensitive adhesive such as rubber, acrylic or urethane can be used.
A concealing layer 91 is overlaid on the adhesive layer 71 to conceal the adhesive force of the adhesive layer 71 on the entire back surface of the tab piece 62 of the label substrate 6. By providing the concealing layer 91, a non-adhesive region 9 that does not adhere to the packaging material 3 is formed on the back surface of the knob piece 62. Thus, since the back surface of the knob piece 62 is not bonded, the knob piece 62 does not adhere to the surface of the packaging material 3. Therefore, when the tack label 5 is peeled off, the tab piece 62 can be easily picked.
The formation method of the concealment layer 91 is not specifically limited, For example, well-known non-adhesion processes, such as coating with ultraviolet curable ink (including printing), coating with ink containing silicone, and pasting a film, are performed. It can be provided by doing.

In addition, an adhesive layer 81 is applied over the pressure-sensitive adhesive layer 71 adjacent to the non-adhesive region 9 on the back surface of the sealing piece portion 61 of the label substrate 6. The adhesive layer 81 is provided in a band shape from one side 61 a of the sealing piece portion 61 to a predetermined width and reaching both sides 61 b and 61 b of the sealing piece portion 61. By providing the adhesive layer 81, the adhesive region 8 is configured in a belt-like range surrounded by one side 61a of the back surface of the sealing piece portion 61 and a part of both side sides 61b and 61b continuous to the one side 61a.
The adhesive layer 81 is provided by applying an adhesive. The adhesive is not particularly limited as long as it can be attached to the surface of the packaging material 3 and cannot be re-applied after peeling. For example, an adhesive (solvent type) that is sticky at room temperature and solidifies over time. Adhesives, emulsion-type adhesives, two-component curable adhesives, etc.), heat-sensitive adhesives that are not tacky at room temperature and develop tackiness upon heating and solidify over time after heating, etc. it can. Among these, it is preferable to use a heat-sensitive adhesive. This is because handling of the sealing tack label 5 is simplified.
As the heat-sensitive adhesive, for example, a hot melt type adhesive, a part coat type heat-sensitive adhesive, or the like can be used.
The hot-melt adhesive is not adhesive at room temperature but can be bonded by heating, and can be applied by heating and melting. Examples of the hot melt adhesive include ethylene resins such as ethylene-vinyl acetate copolymers and ethylene acrylic copolymers, and base resins such as styrene-butadiene block copolymers and additives such as tackifiers. Are blended.
In addition, the part coat type heat-sensitive adhesive is not sticky at room temperature but can be bonded by heating, as in the case of the hot melt type adhesive, and can be applied by printing such as gravure coating. It is an agent. Examples of the part coat type heat-sensitive adhesive include a solution in which a heat-adhesive resin such as ethylene-vinyl acetate copolymer and a tackifier are dissolved or dispersed in an organic solvent or the like, and the solution is printed. It is an adhesive that is used after being coated by the method and then dried.

The softening temperature of each of the heat sensitive adhesives is not particularly limited, but those having a softening point of about 80 to 130 ° C are preferable. This is because if a heat-sensitive adhesive having a too low softening point is used, after the sealing tack label 5 is peeled off, the heat-sensitive adhesive exhibits stickiness due to the room temperature or the body temperature of the person, etc. This is because there is a risk of re-sticking to the surface of 3. On the other hand, if a heat-sensitive adhesive having a too high softening point is used, there is a risk of inconvenience such as deformation of the label substrate 6 when the heat-sensitive adhesive is heated.
Here, the softening point refers to a value measured by a ring and ball method softening point (JIS K 6863).

  The adhesive layer 71 is exposed in a region where the adhesive layer 81 is not provided in the back surface of the sealing piece portion of the label base 6. The area where the pressure-sensitive adhesive layer 71 is exposed corresponds to the pressure-sensitive adhesive area 7, and the pressure-sensitive adhesive area 7 is provided so as to sufficiently cover the takeout port and its peripheral part.

In the above example, the adhesive layer 71 is provided on the entire back surface of the label substrate 6, and the concealing layer 91 and the adhesive layer 81 are overcoated on a desired area of the adhesive layer 71, so that each region 7, Although this is a method for forming 8, 9, the following method may be used instead.
As shown in FIG. 3 (c), the adhesive layer 71 is applied only to the area covering the outlet 2 and its peripheral portion of the back surface of the sealing piece portion 61 of the label base 6 to form the adhesive region 7. To do. Further, the adhesive layer 81 is applied to a band-like region surrounded by one side 61a of the sealing piece portion 61 and a part of both side sides 61b and 61b continuous to the one side 61a to form the adhesive region 8. The back surface of the tab piece 62 exposes the back surface of the label base 6 to be a non-adhesive region 9.

The sealing tack label 5 is usually supplied after being temporarily attached to a release paper.
The tack label 5 is used after being peeled off from the release paper. Next, the adhesive region 7 of the sealing piece portion 61 of the tack label 5 is faced to the take-out port 2 of the packaging material 3 and its peripheral portion, and the tack label 5 is stuck to the packaging material 3. When a heat-sensitive adhesive is used as an adhesive for the adhesive region 8 of the tack label 5, after being attached to the packaging material 3, the adhesive region 8 is heated to a predetermined temperature to adhere the heat-sensitive adhesive. . In this way, as shown in FIG. 1, it is possible to produce a package 1 in which the adhesion area 7 and the adhesion area 8 of the tack label 5 are adhered to the surface of the packaging material 3.
Next, when taking out the goods stored in the packaging material 3, the non-adhesive knob portion 62 is picked by hand, and the tack label 5 is peeled off as shown in FIG. In the tack label 5, the adhesive region 8 is first peeled off from the surface of the packaging material 3, and then the adhesive region 7 is peeled off from the surface of the packaging material 3. In addition, when the adhesion area | region 7 peels, the part 33 enclosed by the fracture | rupture line 21 of the bag main body 31 is cut off from the bag main body 31 with adhering to this adhesion area | region 7, and the extraction port 2 opens. After taking out the product X from the take-out port 2, the tack label 5 is attached again as it was. At the time of this reattachment, the adhesive region 7 is attached to the surface of the packaging material 3. On the other hand, since the adhesive region 8 is made of an adhesive that cannot be re-applied after peeling, the adhesive region 8 does not adhere to the surface of the packaging material 3, and a part of the sealing piece portion 61 is made of the packaging material 3 as shown in FIG. It floats from the surface.
Thus, after reattaching, a part of the tack label 5 is lifted from the surface of the packaging material 3, so that it can be easily determined that the tack label 5 has been peeled once in appearance. Although a part of the tack label 5 may not appear to be completely lifted from the packaging material 3, it can be determined that the adhesion region 8 has been peeled off when the tab 62 of the tack label 5 is picked.

In addition, this invention is not restricted to the said embodiment, A design change can be carried out suitably. Hereinafter, although each modification of this invention is demonstrated, about the structure similar to the said embodiment, description is abbreviate | omitted and a term and a figure number may be used.
It is preferable that the label base material 6 of the sealing tack label 5 is subjected to ruled line processing or embossing. For example, as shown in FIG. 5, a crease line 41 is formed in the adhesive region 8 of the label substrate 6. The crease line 41 is preferably formed from one side 61b of the sealing piece 61 to the other 61b opposite to the side 61b. In particular, as shown in the figure, the crease line 41 is a boundary portion between the adhesive region 8 and the adhesive region 7 or a position in the vicinity of the boundary portion (near the adhesive region), from one side 61b of the sealing piece portion 61 to the other. It is preferable that it is formed over 61b.
The crease line 41 is a long line-shaped dent formed in the thickness direction of the label substrate 6 from the upper surface (or lower surface) of the label substrate 6.
Since the crease line 41 is formed on the label base 6, the label base 6 is curved at the crease 41 after the tack label 5 is peeled off. Therefore, after the tack label is peeled off once, the adhesive region 8 is curved so as to warp upward (or downward) from the surface of the packaging material 3, so that it is easier to determine that the tack label 5 has been peeled once.

Further, in combination with the crease line 41 or in place of the crease line 41, the adhesive region 8 of the label substrate 6 may be embossed. For example, as shown in FIG. 6, a concave emboss 42 is formed on the upper surface of the label substrate 6 in the adhesive region 8 of the label substrate 6. A concave emboss may be formed from the lower surface of the label substrate 6. The emboss 42 is a recess having a predetermined shape formed in the thickness direction of the label substrate 6 from the upper surface (or lower surface) of the label substrate 6, and usually by pressing the label substrate 6 using an emboss roll. Can be formed.
Even when the emboss 42 is applied to the adhesive region 8 of the label base 6 in this way, after the tack label 5 is peeled off once, the adhesive region 8 warps upward (or downward) from the surface of the packaging material 3. Since it is curved, it becomes easier to determine that the tack label 5 has been peeled once.
