Such phrases can only be used to distinguish one component from another. For example, within the scope of the rights of the present invention, the first component may be named the second component, and similarly, the second component may also be named the first component. The phrases "and / or" may include a combination of multiple related description items or any one of multiple related description items.

[0040] The terms used in this application are used solely to describe specific embodiments and are not intended to limit and / or restrict the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as “equipped with” or “having” merely specify the existence of features, figures, stages, operations, components, parts, or combinations thereof described in the specification, and should be understood not to preclude the existence or addition of one or more other features, figures, stages, operations, components, parts, or combinations thereof.

[0041] Throughout the specification, when a part is described as being "connected" or "linked" to another part, this includes not only cases where they are directly connected or linked, but also cases where they are electrically connected with other elements in between. Furthermore, when a part is described as "containing" a certain component, this does not exclude other components unless otherwise specified, but rather means that it may contain other components as well.

[0042] Figure 1 is a perspective view of a contents container according to an embodiment of the present invention, Figure 2 is an exploded view of a contents container according to an embodiment of the present invention, and Figure 3 is a cross-sectional view of a contents container according to an embodiment of the present invention.

[0043] Referring to Figures 1 to 3, the contents container 1000 may include a container section 100, a head section 200, a nozzle 300, and a spout 400.

[0044] The container portion 100 may be made of a packaging sheet, and at least a portion of its peripheral edge may be bonded together to form a storage space inside in which contents are stored. For example, the container portion 100 may be formed by bonding a front packaging sheet and a back packaging sheet together along their peripheral edges, thereby forming a storage space inside in which contents are stored. In this case, the container portion 100 may be called a pouch, but is not limited thereto.

[0045] In embodiments, the contents stored in the container 100 may be liquid, gel, or powder cosmetics. For example, the contents may include lotions, milk lotions, moisturizing lotions, nourishing lotions, skin lotions, skin softeners, skin toners, astringents, massage creams, nourishing creams, moisturizing creams, whitening essences, tone-up creams, sunscreen liquids, sunscreen creams, sunscreen milks, BB creams, makeup bases, foundations, CC creams, concealers, blushers, shading products, eye creams, primers, and the like. However, the present invention is not limited to these, and other dosage forms and types of cosmetics, medical contents, etc., can be applied.

[0046] In this embodiment, the joint area between the front packaging sheet and the back packaging sheet may form a seal. The seal may have enhanced strength, durability, and airtightness compared to other areas of the packaging sheet. Therefore, the seal can prevent the contents from leaking out and maintain the shape of the container 100. Various joining techniques can be applied to form the seal, such as chemical joining using adhesives, internal heat joining (ultrasonic joining, high-frequency joining, etc.), and external heat joining.

[0047] In this embodiment, the front packaging sheet and the back packaging sheet may be separate sheets joined together by bonding. However, this is merely an example, and various configurations are applicable depending on the embodiment. For example, the front packaging sheet and the back packaging sheet may be a single integrated packaging sheet joined together by bonding in a state where at least one region is in contact with the other due to folding and / or bending.

[0048] Depending on the embodiment, a cut-out portion may be formed in the container portion 100. The cut-out portion is intended to facilitate cutting and cutting open the container portion 100, and may be formed by drawing a certain area of ​​the container portion 100 inward.

[0049] The head unit 200 is positioned above the container unit 100, and the contents may be discharged to the nozzle 300 after they have flowed in from the container unit 100.

[0050] In this embodiment, the head portion 200 is formed with an upper and lower section that are in communication, but a storage space may be formed inside so that the contents are temporarily stored and then discharged to the nozzle 300.

[0051] In an embodiment, a biasing portion 210 may be formed on one side of the head portion 200. The biasing portion 210 is made of an elastic material and may elastically deform inward when an external force is applied. Such deformation increases the internal pressure of the head portion 200, which may move the contents inside the head portion 200 to the nozzle 300 and / or facilitate such movement. To facilitate gripping and use, the biasing portion 210 may be formed on the side of the head portion 200. However, the present invention is not limited thereto, and depending on the embodiment, the head portion 200 may not have a biasing portion 210.

[0052] In an embodiment, the head portion 200 may include a body portion 220 and a guide portion 230. The body portion 220 may be vertically penetrating, forming a storage space inside, and biasing portions 210 may be formed on its sides. Alternatively, the guide portion 230 may be positioned at the upper end of the body portion 220 so that the contents are directed toward the nozzle 300 through a communication hole formed in the guide portion 230. Depending on the embodiment, the guide portion 230 and the body portion 220 may be formed integrally or assembled.

[0053] In this embodiment, the communication hole in the guide portion 230 may be formed with a narrow inner diameter. For example, the communication hole may be formed with a narrower inner diameter than the inner diameter of the head portion 200. Since the contents of the head portion 200 are discharged through such a narrow inner diameter communication hole, it is possible to prevent a large amount of contents from flowing into the nozzle 300.

[0054] In one embodiment, the guide portion 230 may include a mounting portion having a locking projection formed along its periphery and placed on the upper end of the body portion 220, an extending portion fitted into the inside of the body portion 220, and a base portion connecting the lower end of the extending portion, with a communication hole formed in a certain area. In this case, the extending portion can be in close contact with the inner surface of the body portion 220 to stably fix the guide portion 230, and leakage of contents along the boundary between the body portion 220 and the guide portion 230 can be prevented. However, the present invention is not limited in any way thereto.

[0055] In an embodiment, the head portion 200 may further include a valve 240 for opening and closing a communication hole in the guide portion 230. Specifically, the valve 240 may seal the communication hole, or, if the internal pressure in the head portion 200 changes due to the biasing portion 210, it may open the communication hole to allow the contents to move toward the nozzle 300. The valve 240 may be, for example, a check valve 240, which may be located within the guide portion 230. However, the present invention is not limited thereto.

[0056] In one embodiment, the valve 240 may include a support portion that is positioned in close contact with the inside of the guide portion 230, an opening / closing projection that moves up and down in response to changes in pressure inside the head portion 200 to open and close the communication hole of the guide portion 230, and at least one bridge connecting the support portion and the opening / closing projection.

[0057] The nozzle 300 is formed above the head portion 200 and may discharge the contents that have flowed in from the head portion 200.

[0058] In this embodiment, the flow velocity of the contents may decrease as they pass through the nozzle 300. The contents with reduced velocity may be discharged in droplet form. Depending on the embodiment, a change in internal pressure due to the biasing unit 210 may promote the discharge of the contents.

[0059] In some embodiments, the inner diameter of the nozzle 300 may be narrowed to prevent the contents from being discharged to the outside of the nozzle 300 due to surface tension. Alternatively, the contents may be discharged after being filled at the upper end of the nozzle 300 (or the nozzle head 320). For this purpose, the inner diameter of the nozzle 300 on the outlet 322 side may be even narrower than other areas (e.g., the nozzle tube 310, the nozzle head 320). However, the present invention is not limited thereto.

[0060] In one embodiment, the nozzle 300 may include a nozzle tube 310 through which contents flow in from the head portion 200 via an inlet 312, and which has a nozzle neck 314 in which the inner diameter decreases and then increases in a certain region, and a nozzle head 320 connected to the nozzle tube 310, with an outlet 322 formed at its upper end.

[0061] In this embodiment, the nozzle neck 314 may have a converging section in which the inner diameter gradually decreases as it moves upward, and a diverging section adjacent to it in which the inner diameter gradually increases upward. The contents passing through the nozzle tube 310 may experience a primary decrease in flow velocity due to the bottleneck effect as they pass through the converging section of the nozzle neck 314. The contents may then enter the diverging section, where the flow velocity may decrease secondarily. In this way, the contents moving along the nozzle tube 310 are prevented from being ejected at high speed (especially due to biasing) by the gradual decrease in flow velocity at the nozzle neck 314.

[0062] In one embodiment, the nozzle head 320 is formed at the upper end of the nozzle tube 310 so as to surround the contents moving from the nozzle tube 310, and an outlet 322 may be formed at the upper end. The contents that have passed through the nozzle tube 310, particularly the nozzle neck 314, move to the nozzle head 320, and at this time, because the flow velocity of the contents is very low, the effect of surface tension can be greatly increased. In addition, since the nozzle head 320 is formed so as to surround the contents, the contents can be filled into the nozzle head 320 without being immediately discharged through the outlet 322. Then, they can be discharged in droplet form through the outlet 322. At this time, the inner diameter of the outlet 322 may be formed to be narrower than, for example, the inner diameter of the nozzle neck 314, to facilitate the formation of droplets of the contents.

[0063] In this embodiment, the contents discharged from the nozzle 300 may pass through the nozzle tube 310, gradually decreasing in speed, before hitting the nozzle head 320 and stopping. The contents inside the nozzle head 320 are difficult to discharge due to surface tension, thereby allowing the contents that have passed through the nozzle neck 314 to gradually fill the inside of the nozzle head 320. A force applied to the filled contents, such as gravity, exceeds the surface tension of the contents at the outlet 322, and consequently, the contents can be gradually discharged from the outlet 322. At this time, the contents can be aggregated into a spherical shape due to surface tension and formed into a droplet shape on the outside of the outlet 322. Subsequently, as the contents are gradually discharged from the outlet 322, the droplet can gradually grow larger, and when the droplet exceeds a predetermined size, it can be pulled away from the outlet 322 and fall. In this case, since the size of the water droplets that are pulled away from the outlet 322 and fall is always the same, the contents can be dispensed in fixed amounts, and the user can finely adjust the amount of contents used by adjusting the number of water droplets that fall.

[0064] In this embodiment, when the user applies force to the biasing unit 210, the internal pressure of the head unit 200 increases, which speeds up the rate at which the contents are filled into the nozzle 300 and promotes the discharge of the contents from the outlet 322.

[0065] In an embodiment, the nozzle 300 may further include a nozzle coupling portion 330 formed on the lower side of the nozzle tube 310 for coupling with the head portion 200. The nozzle coupling portion 330 may include an upper wall covering the upper end of the head portion 200 and a side wall extending downward along the periphery of the upper wall and coupling with the side surface of the head portion 200. The nozzle coupling portion 330 allows the nozzle 300 to be easily coupled with the head portion 200, and in particular, when coupling the nozzle coupling portion 330 with the head portion 200, a guide portion 230 placed inside the body portion 220 may be fitted between the body portion 220 and the nozzle coupling portion 330. However, the present invention is not limited to such shapes.

[0066] In this embodiment, the nozzle tube 310, the nozzle head 320, and the nozzle coupling portion 330 may be formed integrally. Furthermore, at least a portion of the nozzle tube 310, the nozzle head 320, and the nozzle coupling portion 330 may be formed from a transparent or translucent material. However, the present invention is not limited thereto.

[0067] The spout 400 may be connected to the container portion 100 and communicate with the containment space of the container portion 100. Alternatively, it may be connected to the head portion 200 so that the contents flowing in from the container portion 100 move to the head portion 200. Depending on the embodiment, the spout 400 may be formed integrally with the head portion 200 and / or the nozzle 300, or it may be formed by assembly.

[0068] In one embodiment, the spout 400 may include a discharge portion 410, a receiving portion 420, and a connecting portion 430.

[0069] In this embodiment, the discharge section 410 may have a passage for the contents formed through it on its inside, and a coupling section for connecting with the head section 200 may be formed on its outside. The passage for the contents of the discharge section 410 may communicate with the storage space of the container section 100 on its lower side, into which the contents may flow, or the contents may move along the passage for the contents and be discharged on the upper side of the passage for the contents.

[0070] In this embodiment, the receiving portion 420 extends outward from below the coupling portion, but may be formed in a circular, oval, or polygonal flat plate shape. When the head portion 200 is coupled to the discharge portion 410, the receiving portion 420 may support the lower end of the head portion 200 to ensure that the head portion 200 is coupled to the spout 400 more stably. Furthermore, by ensuring that the upper part of the container portion 100 is supported by the bottom surface of the receiving portion 420, it is possible to prevent, for example, the spout 400 from moving into the container portion 100, or conversely, the container portion 100 from moving above the spout 400 (for example, to the discharge portion 410). In addition, when coupling the container portion 100 and the spout 400, the upper end of the container portion 100 may be in contact with the bottom surface of the receiving portion 420 to guide the position of the container portion 100. Depending on the embodiment, when the plug (the plug shown in Figures 7 and 8) 500 is connected to the spout 400, the receiving portion 420 may support the lower end of the plug.

[0071] In this embodiment, the joint portion 430 may be formed to have a predetermined volume below the receiving portion 420 and be joined to the container portion 100. The volume of the joint portion 430 may be formed toward the opposing packaging sheets. Such volume allows the packaging sheets to be separated without sticking together, forming a storage space. Various joining techniques can be applied for joining to the packaging sheets. For example, various joining techniques such as chemical joining using adhesives, internal heat joining (ultrasonic joining, high-frequency joining, etc.), and external heat joining can be applied.

[0072] The contents container 1000 shown in Figures 1 to 3 is merely illustrative, and various configurations can be applied depending on the embodiment to which the present invention is applied.

[0073] Figure 4 is a perspective view of a contents container according to an embodiment of the present invention.

[0074] The contents container 1000' in Figure 4 will be described in the same way as the contents container 1000 in Figures 1 to 3, and any redundant explanations will be omitted below.

[0075] Referring to Figure 4, the container portion 100' of the contents container 1000' may be a pouch formed by joining a front packaging sheet and a back packaging sheet. In this case, the front packaging sheet and the back packaging sheet may be formed integrally and joined together by folding and / or bending so that at least one region is in contact with each other, thereby forming a storage space.

[0076] In this case, the container portion 100' may have a seal formed on only one side in the lateral direction. Since the joining area is reduced, the joining process can be simplified. In particular, extra steps such as arranging separate front and back packaging sheets and spacing them apart can be eliminated.

[0077] The contents container 1000' shown in Figure 4 is merely illustrative, and various configurations can be applied depending on the embodiment to which the present invention is applied.

[0078] Figures 5 and 6 are perspective views of a contents container according to an embodiment of the present invention.

[0079] The contents containers 1000'' in Figure 5 and 1000'''' in Figure 6 will be described in the same way as the contents containers 1000 and 1000'' in Figures 1 to 4, and any redundant explanations will be omitted below.

[0080] Referring to Figures 5 and 6, cut-out sections may be formed in the container sections 100'', 100''''. The cut-out sections are intended to facilitate cutting and opening of the container sections 100'', 100'''', and may be formed by drawing a certain region of the container sections 100'', 100'''' inward.

[0081] The user can use the contents of the container section 100'',100'''' more directly by cutting open the container section 100'',100'''' using the cut-off section. For example, even if a considerable amount of the contents has been used up and it is difficult to dispense any more contents through the spout 400, the user can cut open the container section 100'',100'''' and take out and use the contents remaining inside the container section 100'',100''''. In addition, by separating the container section 100'',100'''' from the spout 400 via the cut-off section, or by separating the remaining container section 100'',100'''' from the spout 400 and some of the container sections 100'',100'''' attached thereto, the separated container sections 100'',100'''' can be recycled. For this reason, the cut-off portion may be positioned within the container portion 100′′,100′′′ adjacent to the underside of the spout 400. However, the present invention is not limited in any way thereto.

[0082] The cut-off portion may be formed in the sealing portion of the peripheral edge of the container portion 100′′,100′′′. Because it is formed in a certain area of ​​the sealing portion, the cut-off portion can prevent the shape of the container portion 100′′,100′′′ from being distorted or the sealing ability of the container portion 100′′,100′′′ from deteriorating.

[0083] The cut sections may be formed so that the spacing gradually narrows as they move inward. In particular, the innermost part of the cut section may be formed to be angular. This is to facilitate cutting open using the cut section.

[0084] The contents containers 1000'', 1000'''' shown in Figures 5 and 6 are merely illustrative examples, and various configurations can be applied depending on the embodiment to which the present invention is applied.

[0085] Figures 7 and 8 are diagrams illustrating a set of containers according to an embodiment of the present invention.

[0086] Referring to Figure 7, the container set 4000 may include a refill container 2000 and an applicator 3000. Specifically, the refill container 2000 may include a container section 100, a spout 400, and a stopper 500. In this case, the refill container 2000 may consist of at least one, and the same or different contents may be stored in each container section 100. The stopper 500 may be attached to the spout 400 in a detachable manner to seal the spout 400. The applicator 3000 may also include a head section 200 and a nozzle 300. In Figure 7, the container section 100 is shown, but this is merely an example, and container sections 100', 100'', 100'''' or other container sections may be provided in the refill container 2000.

[0087] Referring to Figure 8, the contents container 1000 may be manufactured from the container assembly 4000 by removing the stopper 500 of the refill container to expose the spout 400 of the refill container, and then connecting the head portion 200 of the applicator 3000 to the spout 400. For this purpose, the method of connecting the spout 400 to the stopper 500 (e.g., screw-on) and the method of connecting the spout 400 to the head portion 200 (e.g., screw-on) may be the same. This allows the user to easily replace only the refill container while holding the applicator 3000 and using the contents.

[0088] The container set shown in Figures 7 and 8 is merely illustrative, and various configurations can be applied depending on the embodiment to which the present invention is applied.

[0089] Figure 9 shows a perspective view and a front view of an applicator according to an embodiment of the present invention.

[0090] Referring to Figure 9, the applicator 3000' may include a spout 400' and a nozzle 300'. The spout 400' and nozzle 300' of the applicator 3000' will be described in the same manner as the spout 400 and nozzle 300 in Figures 1 to 8.

[0091] In the applicator 3000' of Figure 9, the spout 400' and the nozzle 300' may be formed integrally. That is, the nozzle 300' may extend directly from the spout 400', and therefore, components for connecting with other components (e.g., the head portion), such as the nozzle coupling portion, may be omitted. Similarly, components such as the head portion may also be omitted, and therefore, the contents may flow into the nozzle 300' directly from the discharge portion of the spout 400', rather than from the head portion.

[0092] Furthermore, the applicator 3000' may be made from a recyclable material. The applicator 3000' may be separated from the container and recycled. For example, the applicator 3000' may be made from a single material such as PP or PE, or from a biodegradable material. However, the present invention is not limited in any way to these.

[0093] The applicator 3000' shown in Figure 9 is merely illustrative, and various configurations can be applied depending on the embodiment to which the present invention is applied.

[0094] Figure 10 is a cross-sectional view of a packaging sheet according to an embodiment of the present invention.

[0095] The packaging sheet may be used for the container sections 100, 100', 100'', and 100'''' shown in Figures 1 to 8. However, the present invention is not limited thereto.

[0096] Referring to Figure 10, the packaging sheet 600 may comprise a paper layer 610, a first film layer 620, a second film layer 630, and a printing layer 640.

[0097] The paper layer 610 is a base material made of paper, and for example, the paper layer 610 may be made of chemical pulp such as bleached hardwood kraft pulp, bleached softwood kraft pulp, sulfite pulp, mechanical pulp such as stone-ground pulp, thermomechanical pulp, chemical thermomechanical pulp, deinking pulp (DIP), non-wood fibers obtained from kenaf, bamboo, hemp, etc. For example, the paper layer 610 may be made of Korean paper (Hanji), roll paper, yellow roll paper, kraft paper, white cardboard, tissue paper, art paper, Manila paper, ivory paper, medium-grade paper, rough paper, glassine paper, tracing paper, etc.

[0098] In this embodiment, the paper layer 610 may be compressed. Compression may be performed, for example, by applying heat and pressure while passing the paper layer 610 between two rollers. This allows the surface of the paper layer 610 to be treated and compressed. Compression can improve the density of the paper layer 610 and allow the surface to be formed uniformly. This allows the film layer, printing layer 640, etc. to be uniformly bonded to the paper layer 610, and further improves the barrier function of the paper layer 610 itself.

[0099] In the embodiment, the paper layer 610 may be surface-treated. Surface treatment may be performed by coating the surface of the paper layer 610 with a surface treatment agent. Examples of surface treatment agents include starch, starch derivatives, polyvinyl alcohol (PVA), carboxymethylcellulose (CMC), and latex.

[0100] The first film layer 620 may be placed on the underside of the paper layer 610, preventing the contents inside from being absorbed by the paper layer 610 and blocking gases, oxygen, moisture, ultraviolet rays, etc. from the contents. For example, the first film layer 620 can be made of one or more materials selected from the group consisting of linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), casting polypropylene, polylactic acid, and polybutylene succinate, effectively preventing the contents from being absorbed by the paper layer 610.

[0101] The second film layer 630 can be placed between the first film layer 620 and the paper layer 610 to improve the overall strength of the packaging sheet 600. The placement of the second film layer 630 can effectively improve the problem of the packaging sheet 600 being damaged due to insufficient strength. For example, the second film layer 630 may be made of one or more materials selected from the group consisting of polyethylene terephthalate (PET), glycol-modified polyethylene terephthalate (PETG), post-consumer recycled polyethylene terephthalate (PCR-PET), polyethylene, polypropylene (PP), polyester (PE), polymethyl methacrylate (PMMA), and styrene-acrylonitrile copolymer (SAN).

[0102] In some embodiments, the second film layer 630 may be formed by vapor deposition on the upper surface of the first film layer 620. This ensures that the second film layer 630 is consistent and thin, formed on the upper surface of the first film layer 620, and can then be used integrally with the first film layer 620. For example, the vapor-deposited layer of the present invention may be formed by known vapor deposition techniques such as chemical vapor deposition (CVD) or physical vapor deposition (PVD), and various known vapor deposition techniques can be applied depending on the embodiment.

[0103] In this embodiment, the first film layer 620 and the second film layer 630 may be biodegradable. For this purpose, the first film layer 620 and the second film layer 630 may contain at least one of a biodegradable resin and an oxidative biodegradable resin. Here, the biodegradable resin may include both a natural biodegradable resin produced by polymerizing high molecular weight monomers produced by a fermentation process after producing sugar from biomass through pretreatment and a saccharification process, and a petroleum-based biodegradable resin produced using petrochemical-derived substances. For example, the resin may be selected from the group consisting of polylactic acid (PLA) and its copolymers, polycaprolactone (PCL), polyglycolic acid (PGA), polyethersulfone (PES), polybutylene succinate (PBS), polybutylene succinate adipate (PBSA), cellulosic compounds, polyhydroxyalkylates (PHA), polybutylene adipate terephthalate (PBAT), polybutylene succinate terephthalate (PBST) resins, and mixtures thereof, but is not limited thereto. Furthermore, the oxidative biodegradable resin is manufactured by adding biomass, oxidative biodegrading agents, compatibilizers, biodegradation accelerators, autooxidizing agents, etc., to existing general-purpose plastics, and may contain various types of oxidative biodegradable resins, such as Oxobio-PP (Polypropylene)-based oxidative biodegradable resins and Oxobio-PE (Polyethylene)-based oxidative biodegradable resins, but is not limited thereto.

[0104] In this embodiment, an adhesive layer (not shown) may be provided between the paper layer 610 and the second film layer 630. The adhesive layer is for bonding the second film layer 630 to the paper layer 610 and may be formed, for example, by applying an adhesive to the paper layer 610 and / or the second film layer 630, and then pressing the paper layer 610 and the second film layer 630 together. Since the paper layer 610 is compressed to a high density by the compression process and has high moisture barrier properties, the adhesive can form a single layer between the paper layer 610 and the second film layer 630, and the adhesive can exhibit uniform and improved adhesive properties throughout the entire bonding area.

[0105] In embodiments, the adhesive layer may be formed from a water-degradable adhesive. This makes it easier to separate the second film layer 630 from the paper layer 610 by water decomposition of the adhesive layer. For this purpose, the adhesive may be an emulsion-type aqueous adhesive in which the adhesive is dispersed in water. For example, the adhesive may be an aqueous urethane adhesive. However, the present invention is not limited thereto, and a wide variety of natural aqueous adhesives (e.g., starch, protein, animal glue, casein, natural rubber, latex, etc.) and synthetic aqueous adhesives (e.g., aqueous acrylic adhesives, etc.) can be used.

[0106] In some embodiments, the adhesive layer may be formed from a biodegradable material, similar to the paper layer 610 and the second film layer 630. For example, the adhesive layer may be formed from a biodegradable resin or an oxidative biodegradable resin.

[0107] Depending on the embodiment, the second film layer 630 may be immediately bonded to the paper layer 610. Various bonding techniques can be applied to bond the second film layer 630 and the paper layer 610, such as internal heat bonding (ultrasonic bonding, high-frequency bonding, etc.) and external heat bonding. For example, a heating plate may be pressed against the outside of the second film layer 630 to conduct heat, thereby causing the molten second film layer 630 to adhere to the paper layer 610.

[0108] The printed layer 640 is formed by printing on the upper side of the paper layer 610, and may comprise a first printed layer 641 and a second printed layer 642.

[0109] The first printing layer 641 may be formed by applying water-based ink to the upper surface of the paper layer 610. The first printing layer 641 may form a predetermined pattern, character, picture, or color on the surface of the paper layer 610. Here, water-based ink refers to an environmentally friendly ink containing 90% or more water, such as polyurethane type or acrylic type ink.

[0110] The second printing layer 642 may be formed by overprinting an aqueous coating liquid (for example, an aqueous acrylic coating liquid) onto the upper surface of the first printing layer 641 and the paper layer 610 while the first printing layer 641 is formed. The aqueous coating liquid is overprinted over the entire surface of the paper layer 610, and the second printing layer 642 formed by the aqueous coating liquid can protect the lower first printing layer 641 and the paper layer 610 from external damage. The second printing layer 642 is transparent, and the lower end of the first printing layer 641 can be seen through it from the outside.

[0111] In this embodiment, since the paper layer 610 is compressed to a high density and has high moisture barrier properties, the aqueous ink and aqueous coating liquid are not absorbed by the paper layer 610, or only a very small portion is absorbed by the paper layer 610, and the remaining aqueous ink and aqueous coating liquid can form the first printed layer 641 and the second printed layer 642, respectively.

[0112] Depending on the embodiment, both the aqueous ink forming the first printing layer 641 and the aqueous coating liquid forming the second printing layer 642 may be water-degradable. This allows the printing layer 640 to be separated from the paper layer 610 by water decomposition.

[0113] In this embodiment, a thin film layer (not shown) may be formed on the upper side of the paper layer 610. For example, the thin film layer may be formed by hot stamping a hot stamping foil onto the paper layer 610 and the upper surface of the first printing layer 641 and / or the second printing layer 642. Such a thin film layer can give the packaging sheet 600 a metallic appearance, thereby maximizing its visual appeal to the user.

[0114] In the embodiment, the packaging sheet 600 may further include a water-blocking layer (not shown). The water-blocking layer may be formed by applying a water-blocking liquid to at least one side of the paper layer 610. Since the paper layer 610 is compressed to a high density by compression processing and has high water-blocking ability, even if a water-blocking liquid is applied to the paper layer 610, the water-blocking liquid is not absorbed by the paper layer 610, or only a very small portion is absorbed by the paper layer 610, and the remaining water-blocking liquid can form a single layer on the surface of the paper layer 610. The water-blocking layer may be located between the paper layer 610 and the printed layer 640, and / or between the paper layer 610 and the adhesive layer. That is, by ensuring that the blocking layer is not absorbed by the paper layer 610 and forms a single layer along the paper layer 610, the blocking layer can provide a more uniform and improved water and gas blocking ability. The aqueous barrier liquid may contain a polymer that does not contain hydrophilic groups, such as vinyl chloride polymer, ethylene vinyl alcohol polymer, styrene-butadiene, styrene-acrylic, polyvinyl alcohol, or vinylidene chloride polymer. However, the present invention is not limited to these.

Certain terms have been used here, but these are solely for the purpose of illustrating the invention and are not intended to limit its meaning or the scope of the invention as defined in the claims. Therefore, a person with ordinary skill in the art should understand that a variety of modifications and equivalent other embodiments are possible. Thus, the true technical scope of protection of the invention should be determined by the technical idea of ​​the appended claims.
