Description

Technology Field

[0001] The present invention relates to a paper cap, and more specifically, to a takeout paper cap and a method for molding the same, which can be easily and securely mounted on a container and, as it is made of paper material, can replace conventional synthetic resins and reduce environmental pollution. Background Technology

[0002] Generally, "takeout" refers to the sale of food packaged for carrying and eating, or packaged food.

[0003] In particular, coffee shops store and sell beverages in disposable takeout containers, and these containers consist of a paper cup and a synthetic resin lid that seals the top of the container to prevent overflow and protect the contents, and the contents are stored in the cup and the lid is closed to sell the beverages.

[0004] In addition, as disclosed in Registered Patent No. 10-2019018, the cup lid has an outlet hole formed therein to allow drinking of the beverage contained inside the cup, and this outlet hole allows drinking of the beverage by inserting a straw or by placing one's lips against the cup lid to drink of the beverage contained inside the cup.

[0005] However, conventional takeout cup lids are made of synthetic resin, which poses a problem of causing environmental pollution.

[0006] Accordingly, there is an urgent need for the development of technology that allows for convenient single-use applications while preventing and minimizing environmental pollution. Prior art literature

[0007] Registered Patent No. 10-2019018 {Registration Date: August 31, 2019} The problem to be solved

[0008] Accordingly, the present invention has been devised to resolve the above-mentioned problems, and aims to provide a method for forming a paper cap for takeout that can be easily and securely mounted on a container, and can also replace conventional synthetic resins and reduce environmental pollution by being made of paper material. This is achieved by including an embossing forming step of forming embossing at regular intervals along the edge of a circular paper, a first forming step of forming the paper by a mold to form a first product in which the edge of the embossing formed is folded, and a second forming step of forming a locking part that protrudes in the direction of the center of the first product along the folded edge of the first product. means of solving the problem

Specific details for implementing the invention

[0012] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. The detailed description disclosed below, together with the accompanying drawings, is intended to describe exemplary embodiments of the present invention and is not intended to represent the only embodiment in which the present invention may be practiced.

[0014] Throughout the specification, when a part is described as "comprising" or "including" a component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Furthermore, the term "...part" as used in the specification refers to a unit that performs at least one function or operation. Additionally, "one (a or an)," "one," "the," and similar related terms may be used in the context describing the invention (particularly in the context of the following claims) to include both singular and plural forms, unless otherwise indicated in the specification or clearly contradicted by the context.

[0015] In describing the embodiments of the present invention, specific descriptions of known functions or configurations will be omitted if it is determined that such detailed descriptions could unnecessarily obscure the essence of the invention. Furthermore, the terms described below are defined in consideration of their functions in the embodiments of the present invention, and these definitions may vary depending on the intentions or practices of the user or operator. Therefore, such definitions should be based on the content throughout this specification.

[0016] Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings.

[0017] FIG. 1 is a flowchart illustrating a method for forming a paper cap for takeout according to the present invention, FIG. 2 is a drawing showing paper with embossing formed in the embossing forming step according to the present invention, and FIG. 3 is a drawing showing the first linear step and the second forming step according to the present invention.

[0018] A paper cap for takeout comprises: a circular paper (1); embossing (2) formed at regular intervals along the edge of the circular paper (1); a primary product formed by molding the paper (1) with a mold and folding the edge where the embossing (2) is formed; a catch (4) formed protruding in the direction of the center of the primary product along the folded edge of the primary product and deformed to be more closely attached to the inside by applying additional pressure to the outer surface; and an outflow portion (5) formed on the circular paper (1).

[0019] As illustrated in the drawing, the method for forming a paper cap for takeout includes a coating step (S10), an embossing step (S20), a cutting step (S30), a first forming step (S40), a second forming step (S50), a tight forming step (S60), and a spill forming step (S70).

[0020] The coating step (S10) involves coating at least one side of a paper sheet having a certain thickness to prevent the liquid to be contained in the container from being absorbed.

[0021] The coated paper material is wound into a roll and then unwound and transported, sequentially undergoing an embossing molding step (S20), a cutting step (S30), a first molding step (S40), a second molding step (S50), a close-fitting molding step (S60), and an outflow part forming step (S70).

[0022] The embossing molding step (S20) forms embossing (2) at regular intervals along the edge of the circular paper (1).

[0023] And the cutting step (S30) cuts the coated paper sheet into a circle by a blade.

[0024] This cutting step (S30) can be performed before or after the embossing step (S20). In one embodiment, the paper material is cut into a circle after the embossing step (S20).

[0025] And in the first molding step (S40), the paper (1) is molded by a mold to form a first product (3) with a folded edge and an embossed (2) formed.

[0026] The second molding step (S50) forms a catch (4) that protrudes in the direction of the center of the first product (3) along the bent edge of the first product (3).

[0027] Of course, the embossing molding step (S20), the first molding step (S40), and the second molding step (S50) are equipped with a heating unit (not shown) to maintain a constant temperature, and the paper (1) can be easily molded by this temperature.

[0028] Here, in the embossing molding step (S20), the embossing (2) is formed radially with respect to the center point of the paper (1) as shown in FIG. 2, and is formed with a certain length from the edge.

[0029] And this embossing (2) is molded to protrude 30 to 70% of the thickness of the paper (1).

[0030] Accordingly, when forming with a mold in the first forming step (S40), the edges of the paper (1) that are folded by these embossings (2) can be prevented from being damaged.

[0031] In addition, the catch portion (4) in the second molding step (S50) is formed in the center of the bent edge so that the curling portion (22) of the upper part of the container (20) is caught, as shown in FIG. 3.

[0032] In other words, it is natural that the position of the catch portion (4) is set to correspond to the position of the curling portion (22) of the corresponding container (20).

[0033] Accordingly, the paper cap (10) can be easily and securely attached to the container (20), and since it is made of paper material, it can replace conventional synthetic resin, thereby reducing environmental pollution.

[0034] In the close-fitting molding step (S60), additional pressure is applied to the outer surface of the locking part (4) to deform the locking part (4) so ​​that it is more closely fitted inward, thereby improving the sealing and bonding strength of the paper cap.

[0035] The outflow portion formation step (S70) forms an outflow portion (5) in the center of the circular paper (1).

[0036] This outflow formation step (S70) is formed by cutting other parts so that a part is connected by a blade, and when in use, the cut part is rotated based on the part to open. To prevent the contents from leaking out Thus, the paper cap for takeout is completed. Explanation of the symbols
