Description

Adhesive-free eco-friendly container

The present invention relates to a non-adhesive, eco-friendly container, and more particularly, to a non-adhesive, eco-friendly container capable of attaching a lid to the container without using an adhesive.

Containers made of paper or synthetic resin that hold beverages or drinking products such as milk are usually fitted with lids for easy drinking.

At this time, a connecting member having a screw thread for attaching a lid to the container is attached to the container, and then the lid is fastened.

Here, the connection between the connecting member and the container was mainly done with adhesive, which had the problem of being harmful to the human body.

For example, there was a heat fusion manufacturing device and a food container manufactured by the same, as disclosed in Korean Patent Publication No. 10-2198145, etc.

However, in the case of a heat-melting manufacturing device and a food container manufactured by the same, there was a disadvantage in that the special jig and spout required for heat-melting had to be made of heat-resistant materials because the spout was heat-melted and adhered to the pouch.

For the above reasons, the field is attempting to develop a device that can join lids without adhesive, but has not yet achieved satisfactory results.

Republic of Korea Patent Publication No. 10-2198145

The present invention has been proposed to solve the problems of the above-mentioned prior art, and its purpose is to provide an adhesive-free, eco-friendly container in which a lid can be attached by attaching a lid connecting part to the container without using an adhesive on the container.

In order to achieve the above object, the present invention proposes a non-adhesive, eco-friendly container characterized by including: a receiving portion having a receiving space capable of accommodating contents in a packaging container and a discharge port protruding upward to discharge the contents; a lid portion that seals the discharge port to prevent leakage of the contents; and a lid connection portion that is non-adhesively connected to the discharge port and to which the lid portion is fastened.

The above-mentioned receiving portion includes joining holes formed at regular intervals along the periphery of the discharge port.

The above lid connecting part includes a first member that is closely coupled to the inside of the discharge port; and a second member that is integrally formed with the first member and closely coupled to the outside of the discharge port.

According to the present invention, a non-adhesive, eco-friendly container can attach a lid to a lid connection part without using adhesive on the lid connection part and the container by attaching the first member and the second member of the lid connection part to the container.

It should be noted that the same components in the drawings are indicated by the same symbols wherever possible. Unless otherwise defined, all terms in this specification have the same general meaning as those terms understood by a person skilled in the art to which the present invention pertains, and if there is a conflict with the meaning of a term used in this specification, the definitions used in this specification shall apply. Throughout the specification, when a part is said to "include" a certain component, this does not mean excluding other components, but rather that other components may be further included, unless otherwise specifically stated, and also terms such as "... section", "... module" described in the specification mean a unit that processes at least one function or operation, and this may be implemented by hardware, software, or a combination of hardware and software.

As illustrated in Figure 1, the non-adhesive environmentally friendly container (A) according to the present invention includes a receiving portion (2); a lid portion (5); and a lid connection portion (3).

The receiving portion (2) of the present invention can form a receiving space capable of receiving contents within the packaging container (1).

Here, a discharge port (11) protruding from the upper side of the receiving portion (2) and through which contents are discharged may be included.

At this time, the discharge port (11) may be provided with a joining hole (13) formed at a certain interval along the circumference.

Here, the coupling hole (13) can be connected to the lid connection part (3) as shown in Fig. 2.

At this time, a pair of insertion grooves (15) formed to be inserted to a certain depth along the inner and outer periphery of the discharge port (11) may be provided.

Here, the fitting groove (15) can be connected to the lid connection part (3) to prevent leakage of contents.

The lid (5) of the present invention can seal the discharge port (11) to prevent leakage of contents.

At this time, the lid part (5) can be connected to the lid connection part (3).

The lid connecting part (3) of the present invention can be connected to the discharge port (11) in a non-adhesive manner.

At this time, the lid connecting part (3) may include a first member (31) that is tightly coupled to the inside of the discharge port (11), and a second member (33) that is integrally formed with the first member (31) and tightly coupled to the outside of the discharge port (11).

Here, the first member (31) may be formed to protrude at a position corresponding to the joining hole (13) and may be provided with a first joining projection (311) that is inserted into the joining hole (13).

At this time, the first member (31) may be provided with a first insertion projection (313) that protrudes outward to be inserted into the insertion groove (15).

Here, the second member (33) is formed to protrude at a position corresponding to the joining hole (13), and a first joining projection (331) into which the first joining projection (311) is inserted and fastened may be provided.

At this time, the second member (33) may be provided with a second insertion projection (333) that protrudes inwardly to be inserted into the insertion groove (15).

Here, a fastening means (335) formed along the perimeter on the outer side of the second member (33) to which the lid part (5) is fastened may be provided.

At this time, the fastening means (335) is provided with a screw thread (335a) as shown in Fig. 2 (a) as an example, so that the lid part (5) can be fastened or disassembled by rotating it.

Here, the fastening means (335) is provided with a fixing block (335b) as shown in Fig. 2 (b) as another embodiment, so that when the lid part (5) is moved downward and the lid part (5) is connected to the fixing block (335b), the user can consume the contents.

The method for manufacturing a non-adhesive, eco-friendly container (A) according to the present invention is described in detail as follows.

Figure 4 is a block diagram showing a method for manufacturing a non-adhesive, eco-friendly container.

The container cutting step (S10) cuts the fabric according to the development diagram of the packaging container (1) as shown in Fig. 3, and the development diagram can be changed in various ways depending on the packaging container (1).

At this time, the packaging container (1) can have multiple joining holes (13) punched through the joining hole punching step (S15).

Here, the number of coupling holes (13) can be varied depending on the diameter of the discharge port (11) or the lid connection part (3).

At this time, if only the joining hole (13) is punched, no adhesive is used when joining the packaging container and the lid connecting part (3), so leakage of the contents may occur.

Here, after drilling the joining hole (13), the packaging container (1) is pressed to form a fitting groove (15), so that it can be interlocked with the lid connecting part (3) to prevent water leakage.

At this time, the first member (31) can be joined to the joining hole (13) through the first member joining step (S20).

Here, the first coupling protrusion (331) can be coupled to the coupling hole (13).

At this time, the first insertion projection (313) can be inserted into the insertion groove (15).

Here, the first member (31) can be joined to the second member (33) through the second member joining step (S25).

At this time, the second coupling protrusion (331) can be connected to the first coupling protrusion (331).

Here, the first coupling protrusion (331) has a circular hollow structure with one side open, and the second coupling protrusion (331) is provided in a circular protruding shape so that it can be fitted and coupled to the first coupling protrusion (331).

At this time, the second insertion projection (333) can be inserted into the insertion groove (15).

Thus, when the first member (31) and the second member (33) are combined into the packaging container (1), the packaging container (1) is rolled into a cylindrical shape.

At this time, the container (1) can be completed by heat fusing through the container fusion step (S30).

Here, the fusion point (1a) located at the end of the packaging container (1) can be fused with heat, and the bottom surface can be cut into a circle separately and then fused with heat to complete the container.

At this time, as another example, the bottom surface of the container can be completed by cutting the packaging container (1) as a whole, fusing the ends of the packaging container (1) with heat, folding it, and then fusing the bottom surface again.
