Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a double-sided adhesive tape,

The present invention relates to a double-sided adhesive capable of high frequency induction heating vessel sutures sealing a container having various types of structures on both upper and lower surfaces.

Description of the Related Art [0002] Techniques for sealing a container for protecting and preserving the contents of a container made of a material such as plastic, metal, or glass have been common, and container sealing bodies having various functions and shapes have been widely used.

A conventional way is shown in FIGS. 1A to 1B.

In the internal structure of the conventional compact cosmetic container, in order to protect the contents and prevent the leakage or evaporation of the contents in the form of a container made of a structure having the container 70 and the cover ring 60 due to the characteristics of the product, 60 are heat sealed with a sealing material 5 made of aluminum or the like, or a sticker having an adhesive function is attached to the upper surface of the sealing member 5.

However, conventional products simply seal the thermal container sealing body 5 made of aluminum material on the upper face of the cover ring 60 covered on the container 70, and then attach the cover ring to a compact cosmetic container filled with the contents, The product was sealed using a method of physically applying force to cover the container. However, there has been a problem with the temperature evidences and heat resistance during distribution and preservation.

A conventional container seal made of aluminum or a seal adhesive can not withstand a high temperature of 50-80 degrees and peels off itself from the cover ring or pinhole phenomenon occurs and the contents leak or evaporate There have been many problems in image damage and function of the product.

1c to 1g.

Another method for solving the above problem is a method of sealing the compact cosmetic container according to the patent No. 10-1455977 developed and developed by the Company. As described above, one of the accessories of the compact cosmetic container, that is, The cover ring which has been sealed by applying the registered product 50 to the applicant can not be sealed but basically the cover ring is assembled while being covered with the container, Due to the structure of the product, it is simply pressurized and assembled. This is because it does not apply sufficient pressure, or because of the dimensional tolerance of these accessories, it is not perfect to keep the airtightness, so that the contents leak and evaporate between the gap between the container and the cover ring. After opening, the upper surface of the cover ring on the outside is thermally bonded There was a disadvantage that the strip remained unpleasant.

The conventional container sealing body 50 is composed of an upper layer 30 and a lower layer 40, which will be described below in order from the top to the bottom.

Thereby forming a polyester film 32 having no heat bonding. Next, after forming the intermediate substrate layer 34 and then the polyester film 36, a first thermal adhesive resin layer 38 having thermal adhesiveness is formed to thermally adhere to the lower portion.

The lower layer 40 constitutes the second polypropylene film layer 42 with the second thermally adhesive resin layer having thermal adhesiveness and the heat sealable layer 46 ).

Since the sealing container sealing member 50 can not be bonded on both sides in the past, the container company will deliver the sealing member 60 to the cosmetics company while sealing the upper part of the covering ring 60.

In cosmetics companies, the contents are filled in the container, and the cover ring, which is sealed (sealed), is put on the container and joined.

Therefore, a compact cosmetic container having a tamper function that completely seals both the cover ring 60 and the container 70 is desperately needed.

A container 200;

And a cover ring (300) on the upper part of the container (200)

Wherein the high frequency induction heating vessel sealing body (100) of the present invention is constructed between the container (200) and the cover ring (300) and is integrally sealed when passing through the induction heating apparatus Frequency induction heating container sealing body (100) is applied.

The inner surface of the container 200 and the lower inner surface of the cover ring 300 are sealed with the both surfaces of the uppermost surface and the lowermost surface of the double-faced high frequency induction heating container sock 100 of the present invention Respectively.

The present invention acts as a tamper evident and provides functions for consumer protection.

Figure 2d is a cross-sectional view of the part of Figure 2c.

Figure 3a is a view showing a condition where the container sachet starts to tear in a compact cosmetic container to which the product of the present invention is applied.

When the opening tab 101 at the upper central portion of the induction heating vessel suture body 100 is pulled in the upward direction, the open end of the container suture, which is on the same position line as the inner circumferential surface at the lower portion of the cover ring 300, The opening tab 101 and the opening induction cutting band 102 along the line 104 begin to separate together with the second aluminum foil layer bonded to the lower portion thereof.

Figure 3b is a cross-sectional view of Figure 3a.

FIG. 3c is an enlarged view of a cross-sectional view in which the opening induction cutting line 104 is formed on the double-sided high-frequency induction heating vessel sewing material applied to FIG. 3a.

FIG. 3D is a cross-sectional view showing the state of FIG. 3B further advancing to tearing. FIG.

4a is a view of a first embodiment showing a top surface and a bottom surface of a road, and a method of joining, according to the method of manufacturing the product of the present invention.

The induction heating vessel envelope 100 of the present invention is broadly divided into an upper layer 10 and a lower layer 20 when each layer is viewed in cross section and the upper layer 10 is divided into upper layers 10, Layer will be described for each layer.

Thereby constituting the first heat sealable sealing layer 10-a. Thereby joining the upper inner surface of the cover ring 300.

The first heat-sealable sealing layer 10-a is a layer for sealing the inner surface of the upper part of the cover ring 300 covering the inner container. In order to seal the cover ring 300, the cover ring 300 is made of thermoplastic plastic And the first thermal bonding seal layer 10-a should be made of a thermoplastic material of the same material. Also, the first heat-sealable sealing layer 10-a is preferably polypropylene or polyethylene.

The first heat-sealable sealing layer 10-a serves to engage the inner surface of the upper portion of the cover ring 300.

Here, a printing film layer for printing a design and a trademark or a name for promoting the product may be further provided between the first heat-sealable sealing layer 10-a and the first aluminum foil layer 10-c.

The print film layer 10-b is a selectable layer depending on the presence or absence of printing.

The print film layer 10-b may be left for printing, or the printing layer may be omitted if printing is not required. Hereinafter, the printing film layer will be described. It is preferable that the printing film layer has a thickness of 0.008-0.03 mm.

The material of the print film layer may be a polyester film or a polypropylene film.

The order of forming the above-described layers is not limited to the fixed order, because the lamination of any of the multilayer films may be carried out by changing the order according to the manufacturing process. However, The laminating operation is performed after the printing process is performed first.

Therefore, the above-mentioned products are first printed on a print film layer (polyester film or polypropylene film) and then laminated with another layer.

In the case of a product which does not require printing, the upper layer is formed by omitting the printing film layer. It is also possible to constitute an upper layer with printing by directly printing on the lower surface of the first heat-bonding resin layer 10-a at the upper end portion and the upper surface of the first aluminum foil layer 10-c without the print film layer have.

However, a separate print film layer is necessary because it is convenient to print on a generally thin polyester or polypropylene film layer and it is more convenient to print on the first thermally adhesive resin layer 10-a or the first aluminum foil layer 10-c It is preferable to use a separate printing film because direct printing is difficult and difficult, such as a problem of expansion and contraction of a fabric.

The first aluminum foil layer 10-c is placed in the next layer.

The first aluminum foil layer 10-c is a layer for generating heat by high-frequency induction heating, and the generated heat dissolves the uppermost first heat-sealable sealing layer 10-a by heat transfer, Ring to the inner surface of the upper part of the ring.

The heat generated by the second aluminum foil layer formed on the lower layer is not transferred to the upper portion due to the intermediate substrate layer 10-d to be described below, and the first aluminum foil layer 10-c).

The first aluminum foil layer 10-c is required because the second aluminum foil layer 20-a is required if there is only a second aluminum foil layer 20-a in the lower layer, And the polyester film layer 10-e composed of a relatively thick layer in which the heat is transferred well but the upper direction is relatively thick because the second heat sealing adhesive layer 20-b is directly laminated in the downward direction, Since the heat is blocked by the intermediate base layer 10-d and the first heat-sealable sealing layer 10-a can not be heated, the upper inner surface of the upper cover ring 300 can not be thermally bonded The first aluminum foil layer 10-c is necessarily required to heat the first heat-sealable sealing layer 10-a.

Hereinafter, the intermediate substrate layer 10-d is formed.

The intermediate substrate layer 10-d is a layer composed of a film or a sheet formed by foaming a material such as polyethylene, polypropylene, or ethylene vinyl acetate, The film or sheet is resilient due to the characteristics of the raw material so that the cover ring 300 is covered with the container 200 to have a function of improving the adhesion between the containers when the pressure is applied, It is possible to feel a comfortable grip feeling when the opening tab 101 of the upper layer is held with the fingers due to the intermediate substrate layer having a proper and variable thickness and to strongly hold the opening tab 101. [

Next, a synthetic resin layer having high tensile strength and hardness is provided.

The synthetic resin layer is preferably composed of a polyester layer 10-e.

It has a hardness and serves to tear the foil layer neatly.

The synthetic resin layer is made of a polypropylene or polycarbonate film in addition to a biaxially stretched polyester film, and has high hardness and tensile strength.

As shown in FIG. 3B or FIG. 3D, when the opening tab 101 is lifted upwards, the opening induction cutting strip 102 connected thereto is also subjected to a force in the upward direction and is thermally adhered to the inlet of the container 200, The polyester film and the polypropylene or the polycarbonate due to the high hardness of the biaxially stretched polyester film and the polypropylene or the polycarbonate used as the synthetic resin layer, The polycarbonate film is composed of a second aluminum foil layer 20-a which serves as a scissors when the open-cut induction cut-off band 102 and the heat-sealable band 103 are staggered and separated, And serves to unseal the double-stick adhesive suture layer 20-b while shear breaking.

The polyester film layer 10-e plays a very important role in function, and the polyester film layer has a relatively thick thickness of 0.05-0.2 mm, and the opening tab 101 including the layer and the opening guide And the upper layer 10 including the cutting band 102 has a strong tensile strength.

Next, the first thermal adhesive resin layer 10-f is sequentially laminated and integrated. This completes the upper layer.

The first heat-bonding resin layer (10-f) which is the lower surface of the upper layer is manufactured using the following materials or methods.

 A resin made of a copolymer of ethylene vinyl acetate or ethylene acrylic acid which is thermally adhered to the second aluminum foil layer 20-a which is the upper portion of the lower layer 20 Polymer.

The first thermally adhesive resin layer is coated with (10-f) extrusion equipment or laminated with a film to form a layer.

When the first thermal adhesive resin layer is formed by using a hot melt adhesive, it is possible to use a nylon, an ethylene vinyl acetate, a polyester or the like on the lower surface of the polyester film layer, And the hot-melt adhesive is directly coated on the second aluminum foil layer (20-a) of the lower layer.

The first thermal bonding resin layer 10-f having the function of integrating the upper layer 10 and the lower layer 20 of the sealing material by applying heat and pressure using the first thermal bonding resin layer 10-f (2 kgf / 15 mm is usually used for bonding strength to the aluminum foil layer on the lower side of the polyester layer of the upper layer and a force of 2 kgf / 15 mm or more. As a unit, for example, when two layers are adhered to each other and a certain degree of force is applied to the film, the sample shows a magnitude of 2 kg when separated by holding a sample of 15 mm in width .)

(Ethylene Vinyl Acetate) or a resin made of a copolymer of ethylene acrylic acid (Ethylene Acrylic Acid) having a good heat-bonding property to a metal layer such as aluminum as described above so as to have a strong thermal adhesive force with a force of 2 kgf / Polymer.

The uncovering tab 101, the unsealed inductive cut bands 102, the thermally adhered bands 103, and the unsealed inductive cut lines 104 are formed in advance by cutting and pressing operations.

The upper layer 10 composed of the finished multi-layer film is cut and pressed to form the opening tab 101 and the opening induction cutting band 102 and unnecessary scraps are removed, The open-cut induction cutting band 102, and the heat-sealing suture band 103 are the same as the above-described single-layer structure of the upper layer.

Next, the lower layer will be described.

The lower layer 20 of the induction heating vessel suture 100 is composed of a second aluminum foil layer 20-a and a second thermal bonding seam layer 20-b as a seal layer at the inlet of the actual vessel, The second aluminum foil layer 20-a which is the upper surface of the lower layer 20 is strongly thermally adhered to the first thermal bonding resin layer 10-f which is the lower end surface of the upper layer 10, (100).

The second aluminum foil layer 20-a is a layer for induction heating, and the second heat-sealable sealing layer 20-b, which is the lowermost part of the lower layer in the downward direction, And has a function to make a melted container and a heat seal,

On the other hand, in addition to the second heat-sealable sealing layer, the layer is sealed substantially in the container. Due to the nature of the metal material, permeation of moisture or oxygen from the outside is prevented from blocking the contents, And evaporation. At the time of opening, the second aluminum foil layer serves as a seal to be opened while being shearly broken together with the second heat sealing seal layer in the lower layer.

The second thermal adhesive sealant layer 20-b at the lower portion is positioned at the bottom of the lower layer or the sealing material so that the sealing material is thermally adhered to the container 200, (200). The material of the lower layer may be a heat sealable resin such as polyethylene, polypropylene, amorphous polyester or ethylene vinyl acetate, which has the same thermal adhesiveness according to the material of the container 200 Polymer.

The second thermal adhesive sealant layer 20-b is positioned at the lowermost part of the lower layer 20, that is, the sealing material, and is a layer for allowing the sealing material to be thermally adhered to the container 200, ). The material of the lower layer may be thermally adhered to one or more materials selected from polyethylene, polypropylene, amorphous polyester, and ethylene vinyl acetate having the same thermal adhesiveness according to the material of the container 200 It is composed of Heat Seal Polymer.

4b is a cross-sectional view of a high-frequency induction machine in which both the opening tab 101, the opening induction cutting strip 102, the heat-sealing suture band 103, and the opening induction cutting line 104 are punched by a press and cut- 1 shows a method of making a top surface 10 of a heating vessel suture 100;

Figure 4c is a cross-sectional view of the attachment of the top and bottom surfaces of Figure 4b.

Figure 4d is a view of the double-sided high frequency induction heating vessel suture of the present invention.

The opening tab 101, the opening induction cutting band 102, the heat-sealing suture band 103, and the opening induction cutting line 104 are formed on the upper layer.

Figures 4e and 4f are cross-sectional views and plan views explaining through the operation of punching and cutting the upper layer of Figure 4d with a press.

After forming the film and the sheet of the upper layer 10, the fingers are cut as shown in Fig. 4F in order to form the opening tab 101, the open induction cut band 102, the thermal bonding band 103 and the opening induction cut line 104 The circular shape 110 is removed by a punching operation and the annular shape 120 is also removed by a punching operation and the opening induction cutting line 104 is also completely cut to complete the upper layer.

The operations may be performed simultaneously or sequentially.

5a and 5b are views of a second embodiment showing a method of manufacturing the top and bottom surfaces of a road surface according to the method of manufacturing the product of the present invention.

5A, a method of constructing a container sealing body by another method for forming a container sealing body 100 in which an upper layer 10 and a lower layer 20 are thermally adhered to each other to form an integrated container sealing body 100, The upper layer 10 is divided into the upper layer 10 and the lower layer 20 and the upper layer 10 is formed such that each layer is separated from the upper surface by the first heat sealable sealing layer 10- ), (The print film layer is selectively described in FIG. 4A).

The first aluminum foil layer 10-c, the intermediate substrate layer 10-d, and the synthetic resin layer are selected to have hardness and tensile strength. In the present invention, the structure of the polyester layer 10-e is preferable.

Next, the first thermal adhesive resin layer 10-g is sequentially laminated and integrated. At this time, the first thermal adhesive resin layer 10-g is formed by laminating a first thermal adhesive resin layer made of polyethylene or polypropylene .

There is a method of thermally adhering to the lower layer 20 because the polyethylene or polypropylene is not thermally adhered to the aluminum foil layer so that the upper surface of the second aluminum foil layer 20- And a second heat-bonding resin layer 20-c made of polyethylene or polypropylene having the same material as the lower surface of the layer. The upper layer and the lower layer thus formed are thermally adhered to each other to form an integrated container sack.

Since the polyolefin resin of polyethylene or polypropylene can not be thermally adhered to a metal material such as aluminum, when lamination or coating with the second aluminum foil layer 20-a using an ordinary adhesive agent (a urethane adhesive agent is frequently used) A primer is first applied to the second aluminum foil layer 20-a and then the resin is coated.

Usually, a polyethylene resin is used as the material of the first heat-bonding resin and the second heat-bonding resin layer as in the second embodiment, but in the case of a product which must withstand a temperature of 120 degrees or more like a retort, Resin is used.

Similarly, in the case of the first embodiment, the first heat-bonding resin layer and the second aluminum foil layer 20-a shown in Figs. 4A to 4D are thermally bonded to each other and can not be used in retort products.

The first thermal bonding seal layer 10-a and the second thermal bonding seal layer 20-b are formed on the cover ring 300 to be applied to the high frequency induction heating container seal, It is preferable to use a thermoplastic adhesive resin having the same material as the thermoplastic resin.

Here, the material of the thermoplastic adhesive resin is preferably composed of polyethylene, polypropylene, polyethylene terephthalate, ethylene vinyl acetate, or the like.

If the cover ring and the container are made of glass or a metallic material, the first heat sealable sealing layer 10-a and the second heat sealable seal layer 20-b may be made of an ionomer or an ethylene acrylic acid (Ethylene Acrylic Acid).

In the case where the material of the container is made of glass or a metallic material, the second thermal bonding sealing layer 20-b is preferably made of an ionomer or an ethylene acrylic acid.

This method is advantageous in that the second aluminum foil layer 20-a of the lower layer 20 is not directly exposed to the air to prevent oxidation.

In the structure of the lower layer, the second aluminum foil layer 20-a is a layer for induction heating, and the second heat sealing seal layer 20-a, which is the lowermost part of the lower layer, (20-b) to heat seal the container. On the other hand, the layer is sealed substantially in the container together with the second heat-sealing seal layer. Due to the nature of the metal material, To prevent the contents from being changed by blocking the permeation of moisture or oxygen in the container, and to prevent the contents of the container from leaking or evaporating.
