A second substrate 12 is stacked on the applied surface of the strong adhesive layer 21 and dummy adhesive layer 22, and an adhesive layer 23 and release paper 13 are stacked on the surface of the second substrate 12 so that the release paper 13 serves as the outer surface.

Description

The present invention relates to a sealing seal. Specifically, a sealing seal for the purpose of binding a part of a baggage or a vinyl bag, etc., in which one of the bags is opened and then binding the lower part of the opening. The present invention relates to a sealing seal in which, when an attempt is made to remove the seal, the trace remains and can be seen from the appearance.

In recent years, simple packaging has been performed from the viewpoint of ecological logistics that saves cardboard and cushioning materials. For example, as a simple packing means, pack several small packages in a vinyl bag, tie the part directly under the opening and tie it, seal this part and transport it, or similarly seal the vinyl bag etc. It is also considered to deliver in a foldable container (Oricon) every time. In the latter case, the Oricon itself fulfills the purpose of eco-logistics, since the delivery company collects it and uses it repeatedly.
Such a packing method is often used for handling baggage when passengers use airplanes and for delivering products and souvenirs from rural areas. However, since even a simple package is a personal belonging, it must be prevented from being viewed, used or stolen by others.
For airports and the like for such luggage, sealing seals are conventionally used for bagages, vinyl bags, and the like. However, since these conventional products are intended only for preventing re-sticking, it has been difficult to easily determine whether or not there has been an attempt to open.
Therefore, an object of the present application is to make it easy to visually determine whether or not the sealing seal has been replaced or whether or not the sealing seal is new.

Prior art documents relating to the present application include the following documents. Patent Document 1 is a tape intended to be attached along a closing line generated when assembling a cardboard box, and has a portion having a glue layer over the entire back surface, which is different from the configuration of the present application.

Patent Document 2 is a sealing seal for the purpose of preventing a document such as a sealed letter from being tampered with, and is characterized by having a patterned release agent layer and a colored layer. It differs from the structure of this application in the point which has an adhesive layer in this.

After sealing the contents in a baggage, vinyl bag, cloth bag, etc. that is open on one side, after folding the part close to the opening of the bag and bundling it, and sealing the sealed part so that it cannot be opened. When it is attempted to remove the sealing seal, the trace remains so that it can be easily determined. Or it can be used also for the purpose of proving that it is a new article in an unused state because the pseudo-adhesive part of the sealing seal is not damaged.

The gist of the present invention is that a strong adhesive layer is applied closer to the end of one side surface of the first base material in the form of a tape, and the end is on a plane adjacent to the strong adhesive layer. The strong adhesive layer is formed by forming a pseudo-adhesive layer in parallel on the side far from the part and forming a half-cut part serving as an opening in the first base material of the pseudo-adhesive layer application part. And a second base material is laminated on the coated surface of the pseudo-adhesive layer, and further, an adhesive layer and a release paper are laminated on the second base material surface so that the release paper is an outer surface. There is a seal for sealing.
In the above, a half-cut line is formed on the end side of the first base material to cut the first base material and the strong adhesive layer, and the second base material and the adhesive layer. Alternatively, the second base material may be a thin plastic base material. Moreover, the coloring part may be formed in at least one part of the said half cut part.

When an attempt is made to peel off the sealing seal wrapped around a load or the like, the pseudo-adhesive portion is peeled off, and the pseudo-adhesive filled in the cut portion which is an opening is also removed, so that the history of opening is clarified. Conversely, if the pseudo-adhesive portion is not peeled off or damaged, it can be proved that the sealing seal is unused.
Even if the sealing seal is not forcibly peeled off, as usual, if the first base material on the same side as the adhesive application surface is bonded to the adhesive surface and bound, Due to the swelling force, the pseudo adhesive layer side on the inner side of the bundling portion receives the breaking force earlier and is damaged. Thereby, the use fact of the seal for sealing can be proved reliably.

It is the top view which shows the seal for sealing of this invention, sectional drawing, and a rear view. It is a figure which shows the positional relationship of a strong adhesive bond layer and a pseudo adhesive bond layer. It is a figure which shows the usage method of the seal for sealing. It is a side view which shows the state which wore the seal | sticker for sealing in the load.

Hereinafter, the sealing seal of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view, a cross-sectional view, and a rear view showing a sealing seal according to the present invention. FIG. 1 (A) is a plan view seen from the surface of an adhesive part 2, and FIG. 1A is a cross-sectional view taken along line AA, and FIG. 1C is a rear view.
As shown in the plan view of FIG. 1A, the sealing seal 10 is a first base material in a tape shape (substantially uniform width and length L is 5 to 6 times longer than the width H). An adhesive portion 2 is formed at one end portion of 11. The surface of the adhesion part 2 is covered with the release paper 13 in an unused state.
Usually, the width H is about 5 to 100 mm, and the length L is about 5 to 50 cm although it varies depending on the use object and application.

As shown in the cross-sectional view of FIG. 1B, the bonding portion 2 is formed on the surface of the first substrate 11.
The adhesive part 2 is laminated on the coating surface of the strong adhesive layer 21 and the pseudo adhesive layer 22 applied to the first substrate 11 and the strong adhesive layer 21 and the pseudo adhesive layer 22. It consists of a sheet substrate 12, an adhesive layer 23 laminated thereon, and a release paper 13 (so that the release paper becomes the outer surface).
The second substrate 12 has a width and length that covers the strong adhesive layer 21 and the pseudo adhesive layer 22. The second substrate 12 is provided to hold the pseudo-adhesive layer 22, and there is no difference from a normal adhesive structure when a release paper with an adhesive is directly attached to the first substrate 11. It is. The release paper 13 is a paper that protects the adhesive layer 23.
In FIG. 1, a half-cut line 3 is formed near the end of the first base material 11. However, the half-cut line 3 is not an essential configuration. The half-cut line 3 cuts from the first sheet base material to the adhesive layer 23, and the release paper 13 is not cut. Due to the presence of this half-cut line 3, if the half-cut part on the end side is picked and peeled off together with the release paper, peeling is easier than when there is no picking part for peeling. Become.

As shown in the rear view of FIG. 1C, this sealing seal 10 is characterized in that a half cut portion 6 serving as an opening is formed on the first base material of the pseudo adhesive layer coating portion. In the drawing, the half-cut portions 6 are formed in two triangular shapes, but the shape may be other shapes such as a circle. The size and number can also be changed within a range that fits in the pseudo-adhesive layer coating part. The half cut portion 6 cuts up to the pseudo adhesive layer 22.
A colored portion 7 by printing may be provided on the surface of the half cut portion 6 (the side opposite to the pseudo adhesive layer 22 of the first base material). The colored portion 7 may have the same shape as the half cut portion 6 or may be printed in a slightly larger area. If the pseudo adhesive layer 22 is damaged by forming the colored portion 7, the identification becomes easier.
By forming such a half-cut portion 6 in the first substrate 11 in advance, when the pseudo adhesive layer 22 is peeled off, the half-cut portion 6 is also taken off together with the pseudo adhesive layer. Damage to the agent layer 22 can be distinguished more visually.

FIG. 2 is a diagram illustrating a positional relationship between the strong adhesive layer and the pseudo adhesive layer.
The strong adhesive layer 21 and the pseudo adhesive layer 22 are applied in parallel on the surface of the first substrate 11, but the strong adhesive layer 21 is closer to the end of the first substrate. The pseudo adhesive layer 22 is provided on the side far from the end. This is because it is necessary to provide the pseudo-adhesive layer 22 on the side that is easily subjected to expansion pressure and forced peeling force such as a bundled baggage and a vinyl bag. The pseudo adhesive layer 22 may have a smaller area than the strong adhesive layer 21. This is because the pseudo-adhesive layer 22 itself is not originally intended to bond between the sealing base materials but to determine whether or not it is used.
The strong adhesive layer 21 and the pseudo-adhesive layer 22 may be applied with a slight gap, but a common adhesive material can be used for both by simply providing a release layer on the pseudo-adhesive layer 22. In some cases, there is no need to leave a gap.

The strong adhesive layer 21 is a material that strongly bonds the first base material and the second base material. If the two base materials are to be peeled off, the strong adhesive layer 21 is strong enough to destroy either material. It can be glued. On the other hand, the pseudo-adhesive layer 22 is a layer that pseudo-adheres both base materials and realizes an adhesive state that is easily peeled off when a peeling force is applied between the both base materials. Usually, the adhesive material is not left on the surface after peeling.
Such a pseudo-adhesive structure includes an adhesive made of a vinyl acetate, an ethylene-vinyl acetate copolymer, a vinyl chloride-vinyl acetate copolymer, a urethane resin, an acrylic resin, a cellulose resin, or a mixture thereof. Is preferably used.
This is because the adhesive strength can be adjusted by adjusting the coating amount with one type of adhesive, performing spot-like coating, or using a release agent or a sealing agent in combination.

FIG. 3 is a diagram showing a method of using the sealing seal.
First, as shown in FIG. 3A, the release paper 13 of the sealing seal 10 is peeled to expose the pressure-sensitive adhesive layer 23. Next, it is bent so that the inner surfaces (adhesive application surfaces) of the first base material 11 of the sealing seal 10 are bonded to each other (B). Finally, as shown in FIG. 3 (C), the neck portion 4n of the bag, in which a vinyl or polyethylene bag is packed with a conveyed product and the lower part of the opening is bound, is bound using a sealing seal 10. FIG. 3C is a cross-sectional view of the bag neck 4n as viewed from above.

FIG. 4 is a side view showing a state where the sealing seal is worn on the luggage, and is a state where the sealing seal 10 is attached to the neck portion 4n of the vinyl or polyethylene bag. The bag 4 contains, for example, passenger baggage. In such a bundled state, the folded neck portion of the bag itself expands so as to return to the original state. Therefore, in FIG. Works. As a result, the pseudo-adhesive layer 22 having a weak adhesive force is first destroyed and the trace remains, and the pseudo-adhesive in the cut portion 6 is also removed, so that visual discrimination is easy. The sealing seal 10 may be attached not only to the neck portion at one place but also to two places as shown in FIG. Although not shown, when the neck portion cannot be firmly bound only by the sealing seal, it may be bound using a cloth or paper string.

A vinyl bag or the like with a sealing seal can be used for delivery using an Oricon as described at the beginning. In this case, a management number such as a barcode is attached to the Oricon, the management number is read by a handy reader / writer, and data such as a delivery destination and a client are input and transmitted to the management device at the head office. The barcode is output as a small-sized label (at least the management number is printed) by the reader / writer and the label printer, and affixed to the empty space of the sealing sticker. Thereby, since the integral relationship between the seal for sealing and the Oricon can be confirmed at any time, erroneous delivery can be lost. The delivery destination can be acquired from the management device at the headquarters even if it is not described in the package itself, so there is no mistake in the delivery destination.
A pocket may be provided on the side of the Oricon and a delivery slip and a bar code label may be placed in the pocket.

<Embodiment related to material>
(1) The first base material is generally made of water- and oil-resistant plastic materials such as polyethylene terephthalate (PET) and polyolefin, but tough papers such as kraft paper and water-resistant paper. Coated paper, synthetic paper, paper laminated with a resin film, artificial leather paper, etc. can be used, and non-woven fabric may be used.
(2) The second base material is a material inserted between the adhesive layer 21 and the pressure-sensitive adhesive layer 23, and no special material strength is required. The property that it does not dissolve in the solvent of the adhesive is required. A thin layer (about 6 to 20 μm) of PET, polyethylene, polypropylene, aluminum foil, or the like can be used.
(3) Release layer forming agent For forming the release layer, an ultraviolet curable (UV type) ink for offset printing with a silicone oil added or a silicone acrylate added thereto is used. Ordinary thermosetting release inks can also be used.
(4) A normal pressure-sensitive adhesive having a pressure-sensitive adhesive and release paper pressure-sensitive adhesive action can be widely used for the pressure-sensitive adhesive layer 23. For the release paper, a material that has been subjected to a release treatment with an ultraviolet curable resin, silicon, or the like can be used.

Example 1
A wound biaxially stretched PET film having a width of 220 mm and a thickness of 50 μm was used as the first substrate 11.
A strong adhesive layer 21 having a width of 40 mm and a pseudo-adhesive layer 22 having a width of 10 mm were continuously applied in parallel to the left end portion side of the first substrate 11 from a position 12 mm away from the outermost end portion.
At that time, a wound biaxially stretched polypropylene film having a width of 50 mm and a thickness of 10 μm is used as the second substrate 12, and a substrate having a release paper (width 50 mm) with a rubber-based adhesive layer 23 on the back surface. Was used, and the positions between both substrates were aligned and continuously bonded.
The strong adhesive layer 21 and the pseudo-adhesive layer 22 are made of the same acrylic material, but the pseudo-adhesive layer portion is preliminarily coated with a 10 mm wide release layer on the first base material in advance. Structured.
Thereafter, the half cut line 3 is cut from the first base material 11 to the adhesive layer 23 at a position 15 mm from the leftmost end of the first base material, and the half cut portion 6 is set to the first base material. While putting the base material and the pseudo adhesive layer 22 so as to cut, both ends 10 mm of the first base material were cut and discharged while being cut into a sheet having a length of 300 mm.
Finally, this sheet was cut at intervals of 30 mm to obtain a large number of sealing seals 10 having a length of 200 mm and a width of 30 mm, each having an adhesive portion 2 on the left end side.

(Example 2)
A nonwoven fabric having a width of 160 mm was used as the first substrate 11. In addition, the square-shaped coloring part 7 whose one side is 5 mm was printed on the surface of the pseudo-adhesive application part before application | coating of an adhesive agent.
A strong adhesive layer 21 having a width of 35 mm and a pseudo adhesive layer 22 having a width of 15 mm were continuously applied in parallel on the left end portion side of the first substrate 11 from a position 5 mm away from the outermost end portion.
At that time, a biaxially stretched polypropylene film having a width of 50 mm and a thickness of 10 μm was used as the second base material 12, and a base material having a release paper (width 50 mm) with a rubber adhesive layer 23 on the back surface was used. The positions between the substrates were aligned and bonded together.
The strong adhesive layer 21 and the pseudo-adhesive layer 22 are made of the same acrylic material, but the pseudo-adhesive layer part is preliminarily coated with a release layer having a width of 15 mm on the first substrate. Structured.
Thereafter, the half cut portion 6 was inserted so as to cut the first base material and the pseudo adhesive layer 22 so as to match the shape of the colored portion 7. Further, this sheet was cut at intervals of 25 mm to obtain a large number of sealing seals 10 having a length of 160 mm and a width of 25 mm having the adhesive portion 2 on the left end side.

When the sealing seal 10 obtained in Example 1 and Example 2 is used to seal the neck portion of a polyethylene bag packed with small parcels, and when the sealing seal 10 is a used product, The fact could be reliably determined from the fact that the pseudo adhesive portion 22 was damaged and the pseudo adhesive was removed from the half cut portion 6.
