Description

Container cap and sealing member equipped with an automatic opening function

[0001] The present invention relates to a container cap and a sealing member equipped with an automatic opening function, wherein an opening hook enters between the gasket layer and the seal membrane layer at the outer insertion part of the opening tab and exits upward into the inner insertion part of the opening tab, and as the container cap opens, the opening hook lifts the opening tab, thereby simultaneously removing the seal membrane layer adhered to the lower part of the gasket layer along the inner and outer opening guide lines of the gasket layer, so as the container cap opens, the gasket layer and the seal membrane layer of the sealing member can be opened simultaneously with the opening of the container cap.

[0002] Generally, containers are made of glass or plastic and are used for various purposes to store or preserve medicines, objects, or substances inside.

[0003] Containers need to be airtight for storage, and a lid is necessary for frequent opening and resealing.

[0004] In daily life, containers of various shapes and sizes are used to store and use medicines, food, nuts, and beverages; for these containers that require lids, screw-type lids are most commonly used.

[0005] A screw-type lid is a lid formed with screw threads on the inner side of the lid and interlocked with screw threads formed on the neck of the container in correspondence.

[0006] However, while these screw-type lids are the most commonly used, consumer psychology leads them to suspect that the contents may have already been used.

[0007] In other words, consumers are purchasing the contents rather than the container, but because the lids of the products being sold are easy to open, they may suspect that the contents are partially missing or damaged.

[0008] There is also a one-touch container lid in which an opening hook is formed on the upper part of the container neck and a corresponding groove is formed on the upper part of the inner surface of the lid, but this also has the same problem as above.

[0009] Therefore, depending on the contents, there are cases where additional sealing is required for the applicable containers; thus, the lip of the container is sometimes sealed by adhesion using a composite sealant made of paper, plastic, aluminum foil, etc.

[0010] In addition, a so-called safety container cap with an inwardly protruding projection is additionally formed on the bottom of the lid, and a stopper is formed on the neck of the container to catch the safety container cap. As a result, when the lid is twisted to open it, the safety container cap gets caught on the neck of the container and remains in place, allowing the use of the product to be easily checked visually. A bridge type has also been developed and is being used.

[0011] The shape and sealing method of a container are determined by its contents, and this also affects marketability. However, it is very inconvenient and economically unfeasible to have to continuously change the container and lid according to the selected method, or to change or manufacture either the container or the lid anew.

[0012] In addition, a sealing material is attached to the opening of the container containing the medicine to store the medicine for a long period of time, and the user must tear off the sealing material while the lid is open, and the sealing material is attached with a diameter equal to the outer diameter of the container.

[0013] Accordingly, the user uses a relatively thin tool, such as a fingernail or a utility knife, to peel off the sealing material.

[0014] At this time, if you tear it with your fingernails, there is a problem that some of the user's fingernails may break, and if you use tools such as a utility knife, you may get cut or pierced.

[0015]

[0016] For example, prior art 1 (Korean Utility Model Registration No. 20-0477735) discloses a ‘container lid and container’.

[0017] According to prior art 1, the container lid and container are configured to be connected to the neck portion of the container in a cylindrical shape having an upper surface and a circumferential surface and an open lower surface, thereby enabling the container to be opened and closed. A screw thread is formed around the circumferential of the inner surface, and a safety container cap is additionally formed at the bottom so as not to detach from the container neck portion when separated from the container. A locking groove is formed laterally around the upper circumferential of the inner surface to correspond to a locking member formed laterally around the upper circumferential of the container neck portion. Thus, the locking member can be connected to the container having the locking member formed thereon by being inserted into the locking groove, and the locking member can be separated from the container having the locking member formed thereon by being tilted upward by an external force to be removed from the locking groove.

[0018]

[0019] Prior art 2 (Korean Patent Registration No. 10-2327329) discloses a ‘container cap for a container’.

[0020] A container cap for a container according to prior art 2 comprises a first container cap member made of plastic material and having a coupling portion formed on the outer edge of the bottom surface, and a second container cap member made of aluminum material and fixedly coupled to the first container cap member by the coupling portion of the first container cap member, so that when the first container cap member is opened, the second container cap member is simultaneously opened by the coupling portion. The first container cap member includes an upper surface portion that covers the upper part of a rubber seal inserted into the opening of the container to seal the container, a rim portion that extends downward from the end of the upper surface portion, and a coupling portion in which a cross-section open outwardly along the perimeter of the outer edge spaced from the center of the bottom surface of the upper surface portion is formed in the shape of an 'L'-shaped groove, and the upper end of the second container cap member is engaged and coupled to the groove and integrated by fusion.

[0021] The second container cap member has a catch formed on the inner surface of the upper and lower sides of the side wall, respectively, and is interposed between the rim and the connecting part of the first container cap member, so that the upper catch is caught and fixed to the connecting part of the first container cap member and the lower catch is caught and fixed to the neck of the container, and during the opening process of the first container cap member, the external force applied to the first container cap member is transmitted to the fused part on the outer side so as not to tear and detaches from the container along the first container cap member.

[0022] The objective of the present invention is to solve the problems described above,

[0023] One objective is to open the sealing member's sealing layer and seal membrane layer simultaneously with the opening of the container cap by having the opening hook come into the space between the sealing layer and the seal membrane layer at the outer insertion part of the opening tab and come out upward from the inner insertion part of the opening tab, and as the container cap opens, the opening hook lifts the opening tab so that the seal membrane layer attached to the lower part of the sealing layer along the inner and outer opening guide lines of the sealing layer is simultaneously removed.

[0024] Another objective of the present invention is to ensure operational reliability for the simultaneous opening of a container cap and a sealing member by forming an entry guide so that the opening tab protrudes upward, thereby allowing the opening hook to be more easily caught on the opening tab.

[0025] Another objective of the present invention is to ensure smooth deformation of the shape by forming the opening hook so that it is inclined downward to correspond to the opening direction of the container cap, and also by making the thickness or width of the opening hook thinner as it goes toward the end.

[0026] Another objective of the present invention is to implement various opening forms of a sealing member by selectively forming an opening guide line as an outer opening guide line, an inner opening guide line, and an extended opening guide line, or by diversifying the shape of the opening guide line, and thereby to implement various opening forms of the container opening by taking into account the state of the contents contained in the container or the state of use.

[0027] To achieve the above-mentioned purpose, the container cap and sealing member equipped with an automatic opening function according to the present invention comprises: a container cap having a screw fastening structure with the opening of the container and at least one opening hook on the inner bottom surface; a sealing member comprising a seal membrane layer having at least one laminated structure bonded to the upper surface of the opening of the container, a sealing layer bonded to the upper surface of the seal membrane layer and composed of at least one plastic film or sheet material, an opening tab formed on the sealing layer, and an opening guide line formed on the sealing layer and connected to the opening tab; wherein, when the container cap is rotated in an opening direction to open the container cap from the container, the opening hook of the container cap catches on the opening tab of the sealing member, causing the opening tab to be lifted upward, and the sealing member is automatically opened together with the container cap from the opening of the container.

[0028] The opening hook according to the present invention is characterized by being formed to protrude downwardly from the inner bottom surface of the container cap and having a thickness or width, or both thickness and width, that narrows as it extends toward the end.

[0029] The above-described packing layer according to the present invention is characterized by being composed of a single layer comprising any one of the plastic materials of polyolefin, polyester, polycarbonate, nylon, polystyrene, and PLA (Poly Lactic Acid).

[0030] The above-described packing layer according to the present invention is characterized by being composed of any one of a film or sheet or a foam film or sheet comprising a multilayer structure in which the plastic material is laminated in multiple layers.

[0031] The seal membrane layer of the sealing member according to the present invention is characterized by comprising an aluminum foil layer on which the gasket layer is laminated on the upper side, and a heat sealing resin layer disposed below the aluminum foil layer and bonded to the upper surface of the opening of the container.

[0032] The sealing layer of the sealing member according to the present invention is characterized by comprising an opening tab inner insertion part disposed on the inner side of the opening tab and an opening tab outer insertion part disposed on the outer side of the opening tab.

[0033] The opening tab according to the present invention is characterized by being always separated from the seal membrane layer through a non-adhesive silicone coating treatment on its lower surface.

[0034] The opening tab according to the present invention is further characterized by having an entry guide formed to protrude upward to facilitate the entry of the opening projection.

[0035] The opening guide line according to the present invention is characterized by comprising an outer opening guide line connected to the outer end of the opening tab and an inner opening guide line connected to the inner end of the opening tab.

[0036] The outer opening guide line according to the present invention is formed in an annular shape along the edge of the gasket layer, and is characterized in that when the container cap and the sealing member are opened, a part of the sealing member is attached in a band shape to the upper surface of the opening of the container.

[0037] The outer opening guide line according to the present invention is formed to start from the opening tab and extend across the outermost part of the sealing member in an outward direction, so that when the container tab and the sealing member are opened, the entire sealing member is completely removed from the opening of the container.

[0038] The outer opening guide line according to the present invention is further provided with a non-circular guide line, at least a portion of which is not circular, and the non-circular guide line is formed so as not to come into contact with the inner opening guide line, wherein the opening portion formed by the sealing member is formed to be non-circular and small in comparison to the shape of the upper surface of the opening of the container by the outer opening guide line and the non-circular guide line.

[0039] The outer opening guide line and the inner opening guide line according to the present invention are characterized by being configured to be non-contacting while maintaining a constant distance to prevent the opening tab from breaking.

[0040] In the present invention, the opening hook is inserted between the gasket layer and the seal membrane layer in the outer insertion part of the opening tab and comes out upward from the inner insertion part of the opening tab, and as the container cap opens, the opening hook lifts the opening tab, and the seal membrane layer adhered to the lower part of the gasket layer along the inner and outer opening guide lines of the gasket layer is simultaneously removed, thereby allowing the gasket layer and the seal membrane layer of the sealing member to be opened simultaneously with the opening of the container cap.

[0041] In addition, the present invention can ensure operational reliability for the simultaneous opening of the container cap and the sealing member by forming an entry guide so that the opening tab protrudes upward, allowing the opening hook to be more easily caught on the opening tab.

[0042] In addition, the present invention allows for smooth deformation of the shape by forming the opening hook so that it is inclined downward to correspond to the opening direction of the container cap, and also by forming the opening hook so that its thickness or width becomes thinner towards the end.

[0043] In addition, the present invention can implement various opening forms of a sealing member by selectively forming an opening guide line as an outer opening guide line, an inner opening guide line, and an extended opening guide line, or by diversifying the shape of the opening guide line, thereby enabling various opening forms of the container opening by taking into account the state of the contents contained in the container or the state of use.

[0044] In addition, the present invention can improve economic efficiency and usability by forming an opening guide line on the sealing member, thereby simplifying the lamination structure of the sealing member, as well as diversifying the lamination structure of the sealing member according to the intended use or material.

[0063]

[0064] A container cap and a sealing member equipped with an automatic opening function according to a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0065] As illustrated in FIGS. 1 to 5, the combination of a container cap (150) and a sealing member (130) equipped with an automatic opening function according to a preferred embodiment of the present invention comprises a container (110) capable of holding contents, a sealing member (130) attached to the upper surface (111a) of the opening so as not to let contents escape to the outside through the opening (111) of the container, and a container cap (150) fastened to the upper part of the container (110) so as to be openable and closable.

[0066] First, the container (110) is formed to a predetermined size to accommodate a certain amount of contents, and an opening (111) is formed at the top to allow the contents to be removed. A fastening part (112) is formed on the outer surface of the opening (111) to allow the container cap (150) to be fastened. In this case, the main body (151) of the container cap has a corresponding fastening part (153) formed to correspond to the fastening part (112) of the container, so that the container cap can be coupled to and separated from the container by a screw fastening method. Here, the contents include liquid, solid powder, etc., and may be various forms of substances such as pharmaceuticals, food, health supplements, nuts, beverages, as well as industrial engine oil, pesticides, etc.

[0067] The sealing member (130) is provided with a seal membrane layer (131) that is bonded to the upper surface of the inlet (111) to maintain a sealed state of the container (110), and a sealing layer (133) having at least one laminated structure may be bonded to the upper surface of the seal membrane layer (131).

[0068] First, as shown in FIG. 5, the seal membrane layer (131) of the sealing member may be composed of an aluminum foil layer (131a) and a heat sealing resin layer (131b) bonded to the lower surface of the aluminum foil layer (131a). In this case, the heat sealing resin layer (131b) may be bonded to the upper surface (111a) of the container's opening through heat compression.

[0069] The seal membrane layer (131) can be composed of various materials, which can be composed of various materials according to the sealing strength required depending on the material of the container (110).

[0070] Next, it is preferable that the backing layer (133) of the sealing member be configured to have at least one laminated structure. That is, the backing layer (133) can be composed of various materials such as plastic film, foamed plastic film or sheet, nonwoven fabric, or paper. Accordingly, the backing layer (133) can be composed of a single layer structure made of the above materials or a multilayer structure bonded with two or more materials.

[0071] For example, as shown in “A” of FIG. 5, if the sealing layer (133) is composed of a single layer structure, it may be composed only of a foam layer if it has sufficient strength to allow the seal membrane layer (131) to be opened smoothly and simultaneously maintains cushioning.

[0072] In this case, the barbing layer (133) may be made of a single layer comprising any one of the plastic materials of polyolefin, polyester, polycarbonate, nylon, polystyrene, and PLA (Poly Lactic Acid).

[0073] In addition, as shown in "B" of FIG. 5, when the barbing layer (133) is configured as a multilayer structure, each layer may be composed of two or more layers utilizing functional features. In this case, the barbing layer (133) may be composed of two or more layers among a surface film layer (133a), an intermediate substrate layer (133b), and a rigid film layer (133c) sequentially from the top, and these may be laminated in an optional combination depending on the application.

[0074] In particular, the rigid film layer (133c) may be formed as a single layer comprising any one of the plastic materials polyolefin, polyester, polycarbonate, nylon, polystyrene, and PLA (Poly Lactic Acid) so as to be a film layer having relatively high tensile strength.

[0075] In this case, the barbing layer (133) may be a multilayer structure in which a plurality of plastic materials as described above are laminated, and in this case, it may be made of a film or sheet, or a foam film or sheet.

[0076] An intermediate substrate layer (133b) composed of one or more materials such as plastic foam resin, paper, and non-woven fabric may be formed to improve the perfect adhesion between the container cap (150) and the container (110) at the bottom of the surface film layer (133a) and to prevent heat generated from the aluminum foil layer (131a) of the seal membrane layer (131) due to high-frequency induction heating from being transferred to the upper layer. In this case, a rigid film layer (133c) capable of increasing the tensile strength and hardness of the barbing layer (133) may be formed at the bottom of the intermediate substrate layer (133b).

[0077] In the barbing layer (133) configured as described above, an opening guide line (135) is formed in the inner direction at an appropriate position or length from the edge portion, more specifically from the outermost edge of the barbing layer (133). The opening guide line (135) functions as a guideline that allows the barbing layer (133) to be smoothly damaged or cut when the sealing member (130) is opened by the opening member (160) to be described later. The opening guide line (135) configured in this way may be in a completely cut shape or in a dotted line shape, such as a perforation line.

[0078] The manufacturing of the sealing member (130) as described above is formed by joining the barbing layer (133) and the seal membrane layer (131) and then cutting and punching it into the shape of the sealing member (130), so the manufacturing process is not only simple but also has the advantage of increasing economic efficiency. In this case, it is preferable that the barbing layer (133) and the seal membrane layer (131) overlap each other so that their planar shapes are identical and their planar areas are identical.

[0079] The barbing layer (133) and the seal membrane layer (131) are bonded to each other by an adhesive layer to form the seal membrane layer (131), and the adhesive layer can be configured so that the lower surface of the barbing layer (133) and the upper surface of the seal membrane layer (131) are bonded with an adhesive strength of about 500gf / width of 15mm or more.

[0080] Bonding methods include dry lamination bonding using an adhesive, bonding using an adhesive resin via extrusion lamination, or bonding using a hot melt adhesive. Among these bonding methods, one appropriate bonding method is selected so that the sealing layer (133) and the seal membrane layer (131) can be bonded. Before the bonding process, an opening guide line (135) is formed on the sealing layer (133) using a cutting knife that completely cuts it or a sewing knife that cuts it in a dotted line shape. Additionally, the heat sealing resin layer (131b) coated with a film or polymer is marked with a laser at the opening point so that it can be torn and opened more easily upon opening, thereby allowing the seal membrane layer (131) to be damaged more easily and making it easier to open the container.

[0081]

[0082] As illustrated in FIGS. 1 to 5, the container cap (150) according to the present invention is configured to open and close the opening (111) of the container.

[0083] The container cap (150) is composed of a main body (151) and a corresponding fastening part (152) formed on the inner side of the main body (151), and the container (110) can be opened and closed by means of a fastening part (112) formed on the outer side of the opening (111) of the container.

[0084]

[0085] The sealing member (130) according to the present invention configured as described above deviates from the conventional opening method mentioned in the background art, and an opening member (160) is applied so that the opening of the container's mouth (111) can be opened as the sealing member (130) is damaged or cut simultaneously with the opening of the container cap (150). Below, the opening member (160) will be described in more detail with reference to the attached drawings.

[0086]

[0087] As illustrated in FIGS. 6 to 8, the opening member (160) according to the present invention may be formed on the sealing member (130) and the container cap (150). In this specification, the opening member (160) is described on the premise that it is formed to correspond to each other on the sealing member (130) and the container cap (150). However, when the opening member (160) is formed on the sealing member (130) or the container cap (150), it may have the same or similar shape or function as the opening tab and opening hook described later, and may be configured to open the opening of the container through independent operation.

[0088] First, the opening member (160) may be configured to include an opening tab (161) formed on the sealing member (130) and an opening hook (163) formed on the container cap (150).

[0089] In this case, the opening tab (161) of the opening member may be formed in the sealing layer (133) of the sealing member, and as shown in FIGS. 7 and 8, it may be composed of an opening tab outer insertion part (161a) disposed on the inner side of the opening tab (161) and an opening tab inner insertion part (161b) disposed on the outer side of the opening tab (161). It is preferable that the opening tab inner insertion part (161b) and the opening tab outer insertion part (161a) be manufactured in the shape of holes as shown in the attached drawings. This is to facilitate the insertion of the opening hook (163). However, the opening tab inner insertion part (161b) and the opening tab outer insertion part (161a) may be formed by cutting the sealing layer (133) instead of being in the shape of holes. In this case, the opening hook (163) can be easily inserted by forming an entry guide (161c) that causes the opening tab (161) to protrude upward so that the opening hook (163) can be easily inserted into the opening tab outer insertion part (161a).

[0090] When the opening cap outer insertion part (161a) and the opening tab inner insertion part (161b) are formed in the shape of holes as shown in the attached drawing, it is preferable that the size of the opening tab outer insertion part (161a) be formed larger than the size of the opening tab inner insertion part (161b). This is to allow the opening hook (163) to be inserted more easily when the container cap (150) is opened. That is, when the container cap (150) is opened, the opening hook (163) must rotate in the opening direction of the container cap (150) and be inserted into the opening tab outer insertion part (161a) first. Therefore, it is preferable that the opening tab outer insertion part (161a) be formed larger than the size of the opening tab inner insertion part (161b).

[0091] Next, as shown in FIGS. 6 and 8, the opening hook (163) of the opening member is integrally formed on the inner bottom surface of the main body (151) of the container cap, in which case the opening hook (163) may be formed of a material having elasticity with at least one protrusion.

[0092] In the attached drawing, the opening hook (163) is formed in the shape of three protrusions. However, the number of protrusions of the opening hook (163) can be increased or decreased depending on the size of the container cap (150) or the size of the container. In this case, the opening hook (163) may not be formed integrally with the container cap (150), and in such a case, it may be manufactured in a form in which this member is inserted into the container cap while being formed on a separate disc-shaped member.

[0093] Additionally, assuming that the opening direction of the container cap (150) is counterclockwise, it is preferable that the opening hook (163) be formed with a downward slope such that the distance from the end of the opening hook (163) increases progressively as it moves counterclockwise from the inner bottom surface of the container cap (15).

[0094] In this case, the opening hook (163) is folded in a pressed state against the sealing member (130) when the container cap (150) is closed on the container (120) before the sealing member (130) is opened, but can protrude by exerting elasticity when the container cap (150) is opened. To this end, the opening hook (163) may be formed of plastic or a thin metal material.

[0095] When the opening member (160) configured as described above is rotated in the opening direction to open the container cap (150), the opening hook (163) also rotates in the opening direction and gradually protrudes downward while exerting elasticity in a pressed state. In this case, any one of the protrusions of the opening hook (163) can be inserted into the opening tab outer insertion part (161a).

[0096] In this way, when the opening hook (163) is inserted into the outer insertion part (161a) of the opening tab and continues to rotate, the opening hook (163) gets caught on the opening tab (161). In this state, when the container cap (150) continues to rotate, the opening hook (163) rises upward and lifts the opening tab (161) upward. When the opening hook (163) rotates while catching and lifting the opening tab (161), the sealing member (130) can be damaged or cut by the rotational force of the opening hook (163). In this case, the opening guide line (135) forms a cutting line of the sealing member (130), so that the sealing member (130) can be easily and conveniently cut along the opening guide line (135) and removed from the upper surface of the container's opening.

[0097] If such an opening guide line (135) is not formed, the sealing member (130) may be damaged as if torn by the opening hook (163), and there is a risk that the opening hook (163) may be bent or broken due to excessive force being applied to it. Therefore, the opening guide line (135) ensures stable cutting of the sealing member (130) and prevents excessive force from being applied to the opening hook (163), thereby enabling the removal of the sealing member to be smooth through stable cutting.

[0098] The opening member (160) configured as described above enables the sealing member (130) to be cut by the opening tab (161) and the opening hook (163) inserted into the opening tab outer insertion part (161a), but to ensure more reliable operation, the opening tab inner insertion part (161b) and the entry guide part (161c) may be formed, and the opening hook (163) may be made easier to exert elasticity through changes in thickness or width, or thickness and width.

[0099] First, an opening tab inner insertion part (161b) is formed in the opening tab (161), and it is preferable that the opening tab inner insertion part (161b) be positioned in front of the opening tab outer insertion part (161a) with respect to the opening direction. That is, the opening hook (163) rotates in the opening direction and is primarily inserted into the opening tab outer insertion part (161a), and through continued rotation, the opening hook (163) can secondarily be inserted into the opening tab inner insertion part (161b). Therefore, the opening tab (161) can be completely hooked by being inserted into the opening tab outer insertion part (161a) and the opening tab inner insertion part (161b) of the opening hook (153). In this way, the opening tab outer insertion part (161a) and the opening tab inner insertion part (161b) allow the opening tab to be completely caught on the opening hook (163), thereby enabling the cutting operation of the sealing member (130) to proceed more easily and smoothly.

[0100] Next, an entry guide (161c) protruding upward can be formed to facilitate insertion of the opening hook (163) into the opening tab outer insertion part (161a) where it is primarily inserted from the opening tab (161). Accordingly, the opening hook (163) can be inserted more easily and conveniently into the opening tab outer insertion part (161a) by means of the entry guide (161c), and can also be caught more easily on the opening tab (161).

[0101] Furthermore, it is desirable that the opening hook (163) be formed so that the thickness becomes thinner towards the end side and the width also becomes thinner.

[0102] This not only ensures the elasticity of the opening hook (163) but also makes it easy to insert into the opening tab (161), thereby minimizing the possibility of failure in joining between the opening hook (163) and the opening tab (161). That is, by forming the thickness or width of the opening hook (163) to become thinner toward the end, the shape of the opening hook (163) can be easily deformed, thereby ensuring stable operation.

[0103] In this case, the entry guide (161c) is formed into a convex shape through thermoforming during the manufacture of the sealing layer (133) of the sealing member, thereby allowing the opening hook (163) to enter the opening tab (161) more easily, and also allowing the opening hook (163) to be easily caught on the opening tab (161).

[0104]

[0105] The container cap and sealing member equipped with an automatic opening function according to the present invention, configured as described above, can easily and conveniently cut or remove the sealing member when the opening member is caught on the opening tab when the container cap is opened.

[0106]

[0107] The illustrations in FIGS. 9 to 11 show various embodiments according to the form in which a sealing member is removed from the opening of a container according to the present invention.

[0108] First, the opening guide line (135) according to the present invention may be configured to include an outer opening guide line (135a) connected to the outer end of the opening tab (161) as shown in FIG. 7 (a), and an inner opening guide line (135b) connected to the inner end of the opening tab (161).

[0109] In the illustration of FIG. 9, the outer opening guide line (135a) is formed in an annular shape along the edge of the sealing layer (133), so that when the container cap (150) and the sealing member (130) are opened, a portion of the sealing member (130) may be left in the form of a band (136) on the upper surface (111a) of the container's opening. This can be achieved by the outer opening guide line (135a) forming an annular shape on the inner part of the edge of the sealing layer (133). This type of opening may be a completely partial opening type in which the opening band (136) remains on the upper surface (111a) of the container's opening. In this case, the sealing strength of the sealing member on the upper surface of the container's opening is configured in the form of a weld seal, which requires strong adhesion.

[0110] The city of FIG. 10 is formed such that an outer opening guide line (135a) starts from the opening tab (161) and crosses the outermost part of the sealing member in the outer direction, so that when the container cap (150) and the sealing member (130) are opened, the entire sealing member (130) can be removed from the opening (111) of the container. This type of opening may be a sealing member that opens completely. In this case, the sealing strength of the sealing member on the upper surface (111a) of the opening of the container is composed of a peelable seal with an appropriate strength of 200gf / 15mm - 1,500gf / 15mm.

[0111] The illustration in FIG. 11 is a case where a non-circular guide line (135c) is formed in at least a portion of the outer opening guide line (135a) that is not circular. In this case, the non-circular guide line (135c) is formed so as not to meet the inner opening guide line (135b), and is formed in a straight line or an arc shape, etc., so that by extending the outer opening guide line (135a), the outer opening guide line (135a) and the non-circular guide line (135c) together form a non-circular guide line. Therefore, when opening the container cap and the sealing member, the cut portion of the sealing member can be opened in a shape that is smaller than the shape of the top surface of the container's opening and is not circular. In this case, the sealing member may be partially opened, thus being a partially open type.

[0112] Meanwhile, it is preferable that the outer opening guide line (135a) and the inner opening guide line (135b) according to the present invention be formed so that a certain distance is maintained so that they do not meet each other. This is because if the outer opening guide line (135a) and the inner opening guide line (135b) meet, the neck of the opening tab (161) may be severed. Therefore, it is preferable to prevent the neck of the opening tab (161) from being severed by ensuring that a certain distance is maintained so that the outer opening guide line (135a) and the inner opening guide line (135b) do not meet each other. In this case, it is preferable that the width of the outer opening guide line (135a) be 3mm or more and that it be formed with an appropriate length in the direction inward from the center of the circle.

[0113]

[0114] As described above, when the opening guide line (135) according to the present invention is formed in various shapes as illustrated in FIGS. 9 to 11, the opening shape of the sealing member (130) can be implemented in various ways. This can be effective in that the opening shape of the container opening (111) can be implemented in various ways by considering the state of the contents contained in the container (110) or the state of use.

[0115]

[0116] Although the invention made by the inventors has been specifically described according to the above embodiments, the invention is not limited to the above embodiments and can be modified in various ways without departing from the gist thereof.
