Description

Adhesive container {VESSEL FOR STORING ADHESIVE THEREIN}

The present invention relates to a container for adhesives, and more particularly, by stacking a polyethylene layer on the inner side of a flexible film, it is possible to improve chemical resistance and prevent the adhesive properties from being altered even when the adhesive is stored for a long time. It relates to a container for adhesive.

In general, adhesives such as bonds or glues are used for various purposes in the home or industrial field.

Since the adhesive is a highly reactive material, the adhesive may react with the storage container and change its physical properties when stored in the storage container. Therefore, it is necessary to select a container of appropriate physical properties to store the adhesive.

As an example of such an adhesive container, an adhesive container disclosed in Utility Model Registration Application No. 88-6140 filed on April 29, 1988 (name: adhesive container) is proposed. In the utility model registration application, two types of containers for adhesives are posted.

That is, a container which can store an adhesive by having a tubular container formed of a plastic material and having a predetermined strength to have a space therein to store an adhesive, or a tube shape formed of an aluminum material is posted.

Thus, the appropriate container is selected from the two containers to store the adhesive.

However, in such a container for adhesives, when the plastic cube-shaped container is not a cube-shaped place such as a cave, the corner part or the like does not match the container for the adhesive and cannot be stacked because the storage place is wasted. There is a problem.

In addition, the tube-shaped container is not limited to the storage location because the shape of the tube can be deformed to some extent. However, when the tube is made of aluminum, the tube is bent to cause cracking. Since it is difficult to increase the size and the size thereof is limited, it is difficult to inject a large amount of adhesive.

In addition, the tube-shaped container has a problem that the manufacturing process is complicated because most of the components are aluminum and the manufacturing cost increases, and also to process the aluminum.

In addition, when the lid portion is coupled to the tube-shaped container, there is a complicated problem in that the process of integrally bonding the lid portion made of plastic to the tube made of aluminum.

In addition, when the adhesive storage container is disposed, there is a problem in that the box-type storage container or the tubular storage container is pressurized to reduce the volume.

Accordingly, the present invention has been made to solve such a problem, an object of the present invention is to provide a container for an adhesive that can prevent the deterioration of physical properties even after long-term storage by forming a film layer of a material having excellent chemical resistance inside. It is.

In addition, by cutting and bonding the film of a flexible material to provide an adhesive storage space, to provide an adhesive container that can prevent the occurrence of cracks due to bending even when the size is increased.

And it is providing the container for adhesives which can be integrally joined to the film of a flexible material by a simple process.

In addition, to provide a container for the adhesive can be discarded by simply reducing the volume at the time of disposal.

And by manufacturing a container in a hexahedron shape, when an adhesive agent is filled inside, it is providing the container for adhesives which can laminate | stack a container in multiple layers.

In order to achieve the object of the present invention as described above, the present invention is a container for an adhesive comprising a body in which the adhesive is stored, and a lid portion provided at the inlet of the body to open and close the body,

The body has a space formed therein by the edge portion is bonded to the adhesive can be stored, and includes a film having flexibility, the film is a polyester resin layer provided on the outside; A polyamide layer laminated inside the polyester resin layer; An aluminum layer laminated inside the polyamide layer; And laminated to the inside of the aluminum layer when contacted with the adhesive, provides a container for adhesives comprising a polyethylene layer to prevent corrosion.

As described above, the container for adhesives according to the embodiment of the present invention can improve the chemical resistance by forming a film layer such as linear low density polyethylene on the inner surface to prevent deterioration of the physical properties of the adhesive even when the adhesive is stored for a long time There is an advantage.

In addition, the flexible film composed of the polyester resin layer, the polyamide layer, the aluminum layer, and the polyethylene layer is cut and thermally bonded to provide an adhesive storage space, thereby bending even when increasing the size of the container for the adhesive. There is an advantage that can prevent the occurrence of cracks.

In addition, since the adhesive container is manufactured by bonding the film, the film may be pressed by thinning the film when discarded, thereby reducing the volume and discarding the film.

In addition, by manufacturing the container in a hexahedral shape, there is an advantage that can be laminated in a multi-layered container when the adhesive is filled therein.

Hereinafter, an adhesive container according to an embodiment of the present invention will be described in detail with the accompanying drawings.

1 is a perspective view showing a container for an adhesive according to the present invention, Figure 2 is an exploded perspective view of the lid portion shown in Figure 1, Figure 3 is a cross-sectional view "A-A" of FIG.

As shown, the adhesive container (1) proposed by the present invention is flexible, the space is formed inside the body 3 and the adhesive is stored in the inlet 15 of the body (3) It includes a lid portion 5 for opening and closing the body (3).

In the container for adhesives having such a structure, the body 3 may be provided with a space for storing the adhesive therein by cutting the flexible film into a predetermined shape and bonding the edge portion 7.

In this case, the body 3 may be formed by abutting two films, that is, the first and second films 8 and 10, and bonding the edges 7.

Accordingly, the first and second films 8 and 10 may have a predetermined volume of space formed therein, and the adhesive may be stored therein.

Of course, the body 3 may be bonded to each other by bonding the two films as described above, it is also possible to fold one film to bond the rim (7).

The first film 8 or the second film 10 has a structure in which a plurality of layers 17, 19, 21, and 23 are stacked on each other.

That is, the films 8 and 10 may include a polyester resin layer 17 disposed on the outermost side and a polyamide layer PA stacked on the inner side of the polyester resin layer 17; 19), an aluminum layer 21 laminated on the inside of the polyamide layer 19, and a polyethylene layer 23 laminated on the inside of the aluminum layer 21 and in contact with an adhesive. do.

In the film having such a structure, the polyester resin layer 17 may be PET, PBT, or PEN resin, and is preferably a polyethylene terephthalate (PET) component.

The polyethylene terephthalate is a kind of thermoplastics, has a specific gravity of 0.83, and a melting point of 240 ° C., which can be used at high temperatures. In addition, the polyethylene terephthalate may be used as a container (1) for beverages, foods, etc., because of good printability, such that advertisement text may be printed.

Therefore, the polyester resin layer 17 can be easily described by advertising text and the like by forming the outer appearance of the container (1) for the adhesive.

The polyamide layer 19 is made of polyamide, and the polyamide is a kind of synthetic resin such as nylon and has a amide bond in the polymer main chain.

Such polyamides include nylon 6, nylon 12, nylon 66 and the like, with nylon 66 being preferred in terms of strength.

The polyamide has high strength, high heat resistance and light weight, and has excellent mechanical properties, oil resistance and abrasion resistance, and thus is applied to various fields such as clothing or packaging.

In this way, when the polyamide is applied to the container 1 for adhesives, the container 1 for adhesives maintains sufficient strength even when external force is applied to the container 1 and is stretched or the adhesive is excessively injected. Can be prevented.

On the other hand, the aluminum constituting the aluminum layer 21 is in the form of a foil, the aluminum is a silver-white soft light metal, the malleable (ductility), the ductility (large) it can make a thin foil (箔). In particular, the corrosion resistance is strong and light weight is mainly applied to the packaging container (1).

By applying such physical aluminum to the container for adhesives 1 according to the present invention, appropriate strength can be maintained and weight can be reduced.

The polyethylene layer 23 may include materials such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and the like. And especially linear low density polyethylene.

Such polyethylene is a material having excellent chemical resistance, heat adhesion, rigidity and stress crack resistance.

Therefore, the polyethylene layer 23 is laminated on the innermost side of the container for adhesive 1 and is in direct contact with the adhesive, thereby preventing the physical properties of the polyethylene layer 23 from being deteriorated due to excellent chemical resistance, thereby keeping the adhesive for a long time. have.

In addition, the polyethylene has excellent thermal adhesiveness, and thus thermal bonding is possible even at a relatively low temperature.

That is, the polyethylene can be thermally bonded even in a relatively low temperature range of about 60-160 ℃.

Therefore, when the thermal bonding of the edge portion 7 of the film against each other, as described above, the thermal bonding is possible even at low temperatures can be reduced manufacturing costs.

In addition, since the polyethylene is also excellent in rigidity and stress crack resistance, it is applied to the container for adhesives, so that cracks may be prevented from occurring on the surface of the container 1 even when the adhesive container 1 is bent or crushed. have.

In addition, since the polyethylene has good tensile strength, tensile elongation, rigidity, and the like, the polyethylene can be stably maintained even when the lamination thickness is thin.

Therefore, the film constituting the body (3) can maintain a constant strength even if the thickness of the plurality of layers (17, 19, 21, 23), resulting in a thinner thickness of the container for adhesives (1) can do.

In the above description, the edge portion 7 of the container 1 for adhesives has been described as being bonded by thermal bonding, but of course, bonding can also be performed by an adhesive or the like in addition to thermal bonding.

In addition, the adhesive container 1 may be manufactured in a hexahedral shape, and when the adhesive container 1 is manufactured in the hexahedral shape, the container may be laminated in a multilayer when an adhesive is filled in the inside of the container 1. Therefore, a large amount of containers for adhesives can be stored in a narrow space.

On the other hand, the inlet 15 of the body 3 is provided with a lid portion 5 can open and close the container for adhesives (1).

In more detail, as shown in Figure 2, the lid portion 5 is inserted into the tube 11 is thermally bonded to the inlet 15 of the body (3), and screwed to the insertion tube (11) Thereby including a cap 9 for opening and closing the inlet 15.

In the lid part having such a structure, when the insertion tube 11 is thermally bonded to the body 3, the insertion tube 11 is first inserted into the inlet 15 of the body 3.

Then, the outer circumferential surface of the insertion tube 11 is in uniform contact with the inner circumferential surface 13 of the inlet (15). At this time, since the film forming the body 3 is a material having flexibility, it can be easily in contact with the outer peripheral surface of the insertion tube (11).

In this state, heat can be applied to the edge of the inlet 15 so that the outer circumferential surface of the insertion pipe 11 and the inner circumferential surface 13 of the inlet 15 can be thermally bonded to each other.

As a result, the lid part 5 can be easily integrated into the inlet 15 of the container 1 for adhesives by a low temperature thermal bonding.

Hereinafter, with reference to the accompanying drawings will be described in more detail the manufacturing method of the container for adhesives according to the present invention.

2, 3, and 4, the manufacturing method of the container for adhesives proposed by the present invention is to prepare a film consisting of a plurality of layers (17, 19, 21, 23) ( S100); Cutting the film manufactured in the step S100 and manufacturing a body of the container for an adhesive, in which a space for storing the adhesive is provided by bonding the edges 7 of the cut film to each other (S110); And inserting the lid portion 5 into the inlet 15 of the body 3 to close the lid portion 5, and coupling the lid portion 5 integrally by thermal bonding (S120).

In the method for producing a container for adhesives, in the film manufacturing step (S100), the polyester resin layer 17, the polyamide layer 19, the aluminum layer 21, and the polyethylene layer 23 from the outside. By sequentially laminating inwardly, the films 8 and 10 having flexibility can be produced.

The film may be manufactured by various manufacturing processes. That is, in the state where the polyester resin layer 17, the polyamide layer 19, the aluminum layer 21, and the polyethylene layer 23 are each manufactured in the form of a film, the films are thermally laminated in the state of being sequentially stacked. Can be bonded.

Alternatively, after the polyester resin layer 17 is applied and laminated on the outer side of the polyamide layer 19, the aluminum layer 21 is formed inside the polyamide layer 19.

The polyethylene layer 23 may be formed by laminating the linear low density polyethylene inside the aluminum layer 21.

In addition to the above process, the film may be manufactured by various processes such as inflation process, solution casting process, melting process, melt compression process, melt extrusion process, bubble blown film process, calender process, and sintering process.

At this time, since the physical properties of the polyester resin layer, the polyamide layer, the aluminum layer, and the polyethylene layer have been described above, a detailed description thereof will be omitted.

As such, after the four layers 17, 19, 21, and 23 are sequentially stacked, the step S100 of manufacturing the flexible film is completed, and manufacturing the body 3 of the container 1 for the adhesive. S110 is performed.

That is, in the step S110, the flexible first and second films 8 and 10 are cut, and after facing each other, the edge portions 7 are integrally bonded by thermal bonding.

In this case, the polyethylene is a material excellent in thermal bonding, heat bonding may be carried out in a relatively low temperature range of about 80 to 160 ℃.

In addition to the thermal bonding, the edge portion may be joined by an adhesive or the like.

As such, after cutting the first and second films 8 and 10 and bonding the edge portion 7 to manufacture the body 3 of the container 1 for adhesives (S110), the lid is coupled. Step S120 proceeds.

In the lid coupling step (S120), first insert the insertion tube 11 into the inlet 15 of the body (3). Then, the outer circumferential surface of the insertion tube 11 is in uniform contact with the inner circumferential surface 13 of the inlet (15).

At this time, since the film forming the body 3 is a material having flexibility, it can be easily in contact with the outer peripheral surface of the insertion tube (11).

In this state, heat can be applied to the edge of the inlet 15 to thermally bond the outer circumferential surface of the insertion pipe 11 and the inner circumferential surface 13 of the inlet 15.

As a result, the lid part 5 can be easily integrated into the inlet 15 of the container 1 for adhesives by a low temperature thermal bonding.

Through the above steps, a container for an adhesive, which is flexible and thermally bondable even at a low temperature, may be manufactured.
