Description

Technical Field

[0001] This invention relates to a container cap and a sealing component with an automatic opening function. The opening hook enters from the outer insertion part of the opening pull ring between the backing layer and the sealing film layer, and disengages towards the upper side of the inner insertion part of the opening pull ring. When the container cap is opened, the opening hook lifts the opening pull ring, and the sealing film layer adhered to the lower part of the backing layer is removed simultaneously along the inner and outer opening guide lines of the backing layer. Therefore, with the opening of the container cap, the backing layer and the sealing film layer of the sealing component can be opened simultaneously. Background Technology

[0002] Generally, containers are made of glass or plastic and have various uses for storing or preserving medicines, articles, or substances.

[0003] For storage and preservation, containers need to be sealed; for easy opening and sealing, containers need lids.

[0004] In daily life, containers used for storing and using medicines, food, nuts, beverages, etc. come in various shapes and sizes, and the most common type of lid for these containers is the screw-top lid.

[0005] A screw cap is a cap with threads formed on the inside of the cap that connect with corresponding threads formed on the neck of the container.

[0006] However, although this type of screw cap is the most common, consumers may suspect that the contents have already been used.

[0007] That is, consumers buy the contents, not the container, but because the lids of the goods being sold are easy to open, they may suspect that the contents are partially insufficient or damaged.

[0008] Another type is a one-touch container lid with an opening hook formed on the upper part of the container neck and a corresponding groove formed on the upper inner side of the lid, but this also has the above-mentioned problems.

[0009] Therefore, depending on the contents, containers sometimes need to be further sealed by using sealing materials made of composite materials such as paper, plastic, and aluminum foil to seal the inlet surface (lip) of the container through adhesives or other means.

[0010] In addition, a safety container cap with a protrusion on the inside is formed at the lower end of the cap, and a stop is formed at the neck of the container to hook the safety container cap. When the cap is turned to open, the safety container cap will hook onto the neck of the container and remain there. Therefore, a bridging type has been developed that allows for easy visual confirmation of whether the product is in use.

[0011] The shape and sealing method of a container are determined by its contents, which also affects its commercial viability. It is very inconvenient and economically impractical to constantly change the applicable container and lid, or change one of the containers or lids, or remake them based on the chosen method.

[0012] In addition, for the purpose of long-term storage of medicines, a seal should be affixed to the inlet side of the container. Users need to grasp the seal and tear it off while the lid is open. The diameter of the seal should be the same as the outer diameter of the container.

[0013] Therefore, in order to remove the seal, users use thin tools such as fingernails or cutters to tear it off.

[0014] At this point, if you tear it open with your fingernail, not only will your fingernail break off, but you may also cut or puncture your fingers when using tools such as a cutter.

[0015] For example, the following patent document 1 discloses a "container cap and container".

[0016] According to the following patent document 1, a container cap and container have an upper surface and a circumferential surface, and a lower surface that is open and cylindrical. The container cap is attached to the neck of the container, allowing the container to be opened and closed. A thread is formed around the inner side, and a safety container cap is formed at the lower end that will not separate from the container neck when separated from the container. In order to correspond to the hook end that protrudes laterally around the uppermost part of the container neck, a hook groove that is recessed laterally is formed around the uppermost part of the inner side. The hook end is inserted into the hook groove and attached to the container forming the hook end. The hook end is lifted upward by external force to disengage from the hook groove and separate from the container forming the hook end.

[0017] The following patent document 2 discloses a "container cap for a container".

[0018] The container cap of the following patent document 2 includes: a first container cap component made of plastic and having a connecting portion formed on its bottom outer contour; and a second container cap component made of aluminum, which is fixedly connected to the first container cap component through the connecting portion, wherein opening the first container cap component simultaneously opens based on the connecting portion, wherein the first container cap component includes: an upper part covering the upper part of a rubber plug inserted into the container entrance to seal the container; an edge part extending downward from the end of the upper part; and a connecting portion that opens outward from the periphery of the outer contour spaced apart from the center of the bottom surface of the upper part. The second container cap component is attached to the upper end of the groove in the shape of a slot, and the two components are fused together to form a single unit.

[0019] The second container cap component has hooks formed on the inner sides of the upper and lower ends of the sidewall, respectively, sandwiched between the edge and the joint of the first container cap component. The upper hook is hooked to the joint of the first container cap component and fixed thereon, and the lower hook is hooked to the neck of the container and fixed thereon. During the opening process of the first container cap component, the external force applied to the first container cap component is transmitted to the fusion part of the outer contour without cracking, and it detaches from the container along the first container cap component.

[0024] (Patent Document 0003) Korean Patent Publication No. 10-2014-0065248 Summary of the Invention

[0025] The technical problem that the invention aims to solve

[0026] The purpose of this invention is to solve the above-mentioned problems. One of its objectives is to open the hook from the outer insertion part of the opening pull ring between the backing layer and the sealing film layer, and disengage it from the upper side of the inner insertion part of the opening pull ring. When the container cap is opened, the opening hook lifts the opening pull ring, and along the inner and outer opening guide lines of the backing layer, the sealing film layer adhered to the lower part of the backing layer is removed at the same time. Therefore, as the container cap is opened, the backing layer and the sealing film layer of the sealing component can be opened simultaneously.

[0027] Another object of the present invention is that, with the opening pull ring protruding upward to form an entry guide, the opening hook can be more easily hooked onto the opening pull ring, so as to ensure the operational reliability required for simultaneous opening of the container cap and sealing components.

[0028] Another objective of the present invention is that the opening hook is tilted downward in a manner corresponding to the opening direction of the container cap, and the thickness and even the width of the opening hook become thinner as it gets closer to the end side, so that the shape deformation becomes smoother.

[0029] Another object of the present invention is to selectively form an outer opening guide line, an inner opening guide line, and an extended opening guide line for the opening guide line, or to diversify the shape of the opening guide line to present multiple opening forms of the sealing component, and to present multiple opening forms of the container inlet considering the state or usage state of the contents in the container.

[0030] means for solving problems

[0031] To achieve the aforementioned objective, the container cap and sealing component of the present invention with an automatic opening function include: a container cap, which is fastened to the inlet of the container by a screw fastening structure, and has at least one opening hook on its inner bottom surface; and a sealing component, which consists of a sealing film layer joined to the upper end face of the inlet of the container and having at least one layered structure, a backing layer joined to the upper part of the sealing film layer and made of at least one plastic film or sheet material, an opening pull ring formed in the backing layer, and an opening guide line formed in the backing layer and connected to the opening pull ring. In order to open the container cap, when the container cap is rotated in the opening direction, the opening hook of the container cap is hooked by the opening pull ring of the sealing component, and the opening pull ring is lifted upwards. From the inlet of the container, the sealing component and the container cap are automatically opened.

[0032] The invention is characterized in that the opening hook protrudes obliquely downward from the inner bottom surface of the container cap, and the thickness or width, or both, become narrower as it approaches the end.

[0033] The present invention is characterized in that the backing layer is composed of a single layer of a plastic material including polyolefin, polyester, polycarbonate, nylon, polystyrene, and PLA (polylactic acid).

[0034] The present invention is characterized in that the backing layer is composed of one of the following: a multilayer structure comprising a film or sheet or a foam film and sheet, comprising multiple layers of the plastic material.

[0035] The invention is characterized in that the sealing film layer of the sealing component includes an aluminum foil layer stacked on top of the backing layer and a heat-sealing resin layer disposed below the aluminum foil layer and bonded to the upper end face of the inlet of the container.

[0036] The present invention is characterized in that the backing layer of the sealing component includes an inner insertion portion of the opening pull ring disposed on the inner side of the opening pull ring and an outer insertion portion of the opening pull ring disposed on the outer side of the opening pull ring.

[0037] The present invention is characterized in that the lower surface of the opening pull ring is treated with a non-adhesive silicon coating, and is always separated from the sealing film layer.

[0038] The present invention is characterized in that the opening pull ring also has an upwardly protruding entry guide portion to facilitate entry of the opening protrusion.

[0039] The present invention is characterized in that the opening guide line includes an outer opening guide line connected to the outer end of the opening pull ring and an inner opening guide line connected to the inner end of the opening pull ring.

[0040] The invention is characterized in that the outer opening guide line is formed in a ring along the edge of the backing layer, and when the container cap and the sealing member are opened, a portion of the sealing member is attached to the upper end face of the container inlet in a strip form.

[0041] The invention is characterized in that the outer opening guide line starts from the opening pull ring, extends outward from the sealing member, and crosses the outermost side, so that when the container pull ring and the sealing member are opened, the sealing member is completely removed from the inlet of the container.

[0042] The invention is characterized in that the outer opening guide line also has at least a portion of non-circular guide lines that are not circular, and the non-circular guide lines do not contact the inner opening guide line. Based on the shape of the opening portion of the sealing component through the outer opening guide line and the non-circular guide lines, the upper end face of the container entrance is non-circular and smaller.

[0043] The present invention is characterized in that, in order to prevent the opening pull ring from breaking, the outer opening guide line and the inner opening guide line are kept at a certain distance and do not contact each other.

[0044] Invention Effects

[0045] According to the present invention, the opening hook enters from the outer insertion part of the opening pull ring between the backing layer and the sealing film layer, and disengages towards the upper side of the inner insertion part of the opening pull ring. When the container cap is opened, the opening hook lifts the opening pull ring, and the sealing film layer adhered to the lower part of the backing layer is removed simultaneously along the inner and outer opening guide lines of the backing layer. Therefore, as the container cap is opened, the backing layer and the sealing film layer of the sealing component can be opened simultaneously.

[0046] Furthermore, according to the present invention, with the opening pull ring protruding upward to form an entry guide, the opening hook can be more easily hooked onto the opening pull ring, thereby ensuring the operational reliability required for simultaneous opening of the container cap and sealing components.

[0047] Furthermore, according to the present invention, the opening hook is inclined downward in the direction corresponding to the opening direction of the container cap, and the thickness and even the width of the opening hook become thinner as it gets closer to the end side, so that the shape deformation becomes smoother.

[0048] Furthermore, according to the present invention, for the opening guide line, an outer opening guide line, an inner opening guide line, and an extended opening guide line can be selectively formed, or the shape of the opening guide line can be diversified to present multiple opening forms of the sealing component, and considering the state or usage state of the contents in the container, multiple opening forms of the container inlet can be presented.

[0049] Furthermore, according to the present invention, by forming an opening guide line on the sealing component, not only can the stacked structure of the sealing component be simplified, but the stacked structure of the sealing component can also be diversified according to the application or material, thereby improving economy and usability.

[0068] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily implement the invention.

[0069] However, since the description of the invention is only for structural or functional explanation of the embodiments, the scope of the invention should not be limited to the embodiments described herein.

[0070] For example, various modifications can be made to the embodiments and they can have multiple forms, so it should be understood that the scope of the present invention includes equivalents that can realize the technical idea.

[0071] Furthermore, the purposes or effects presented in this invention are not necessarily all or only included in the specific embodiments, and therefore should not be construed as limiting the scope of the invention thereto.

[0072] In this specification, these embodiments are provided to ensure the completeness of the disclosure of the invention and are intended to fully inform those skilled in the art of the scope of the invention. Furthermore, the invention is defined only within the scope of the claims.

[0073] Therefore, in some embodiments, well-known components, well-known operations, and well-known technologies are not specifically described in order to avoid the invention being misinterpreted.

[0074] On the other hand, the meanings of the terms described in this invention are not limited to dictionary definitions and should be understood as follows.

[0075] All terms used herein, unless otherwise defined, have the same meaning as commonly understood by one of ordinary skill in the art.

[0076] Terms defined in commonly used dictionaries should be interpreted as having the meaning consistent with the context of the relevant art, and should not be interpreted as having an idealized or over-formal meaning unless explicitly defined in this invention.

[0077] The preferred embodiments of the container cap and sealing component with automatic opening function of the present invention are described in detail below with reference to the accompanying drawings.

[0078] like Figures 1 to 5 As shown, the preferred embodiment of the present invention comprises a container cap 150 with an automatic opening function and a sealing member 130, which includes: a container 110 for holding contents; a sealing member 130 for engaging with the upper end face 111a of the inlet to prevent contents from flowing out through the inlet 111 of the container to the outside; and a container cap 150 for being openably and closably fastened to the upper part of the container 110.

[0079] First, the container 110 has a predetermined size to hold a certain amount of contents. An inlet 111 is formed at the top to allow the contents to be removed. A fastening part 112 is formed on the outer side of the inlet 111 to secure the container cap 150. In this case, the main body 151 of the container cap forms a corresponding fastening part 153 corresponding to the fastening part 112 of the container, allowing the container cap and container to be joined and separated by screws. The contents include liquids, solid powders, etc., and can include not only medicines, but also food, health foods, nuts, beverages, as well as various forms of substances such as industrial oil and pesticides.

[0080] The sealing member 130 has a sealing membrane layer 131 that is engaged with the upper end face of the inlet 111 to maintain the container 110 in a sealed state, and a backing layer 133 having at least one or more laminated structures is engaged with the upper part of the sealing membrane layer 131.

[0081] First, such as Figure 5 As shown, the sealing film layer 131 of the sealing component is composed of an aluminum foil layer 131a and a heat-sealing resin layer 131b bonded to the underside of the aluminum foil layer 131a. In this case, the heat-sealing resin layer 131b can be bonded to the upper end face 111a of the container inlet by heat pressing.

[0082] The sealing membrane layer 131 is made of a variety of materials, depending on the material of the container 110 and the required sealing strength.

[0083] Secondly, preferably, the backing layer 133 of the sealing component has at least one layered structure. That is, the backing layer 133 is made of various materials such as plastic film, foamed plastic film or sheet, non-woven fabric, and paper. Therefore, the backing layer 133 has a single-layer structure made of the aforementioned materials or a multi-layer structure made of two or more materials joined together.

[0084] For example, such as Figure 5 As shown in “A”, when the backing layer 133 is a single-layer structure, if it has sufficient strength to ensure that the sealing film layer 131 can be opened smoothly while maintaining cushioning, it can be composed of only a foam layer.

[0085] In this case, the backing layer 133 is composed of a single layer of one of the following plastic materials: polyolefin, polyester, polycarbonate, nylon, polystyrene, and PLA (polylactic acid).

[0086] And, as Figure 5 As indicated by "B", when the backing layer 133 has a multi-layer structure, it can be composed of two or more layers by utilizing the functional characteristics of each layer. In this case, the backing layer 133 is composed of two or more layers from the top, namely the surface thin film layer 133a, the intermediate substrate layer 133b, and the rigid thin film layer 133c, and can be selectively combined and stacked according to the application.

[0087] In particular, the rigid film layer 133c is composed of a film layer with high tensile strength, and is composed of a single layer of one of the following plastic materials: polyolefin, polyester, polycarbonate, nylon, polystyrene, and PLA (polylactic acid).

[0088] In this case, the backing layer 133 may have a multilayer structure of multiple layers of plastic materials as described above, and may be composed of films or sheets or foam films and sheets.

[0089] To facilitate a perfect fit between the container cap 150 and the container 110 and the lower part of the surface film layer 133a, an intermediate substrate layer 133b can be formed by transferring heat generated in the aluminum foil layer 131a of the sealing film layer 131 through high-frequency induction heating to the upper layer. This intermediate substrate layer 133b is composed of one or more materials, such as foamed resin made of plastic, paper, and non-woven fabric. In this case, a rigid film layer 133c can be formed below the intermediate substrate layer 133b to increase the tensile strength and hardness of the backing layer 133.

[0090] As described above, more specifically, an opening guide line 135 is formed on the inner side of the outermost portion of the backing layer 133 at an appropriate position and length. This opening guide line 135 guides the smooth breaking or even cutting of the backing layer 133 when the sealing member 130 is opened based on the opening member 160 described later. The opening guide line 135 is formed either in a completely cut shape or as a dotted line, like a zigzag line.

[0091] As described above, the sealing member 130 is formed by cutting and stamping in the shape of the sealing member 130 after joining the backing layer 133 and the sealing film layer 131. Therefore, the manufacturing process is simple and also has the advantage of improving economy. Preferably, the backing layer 133 and the sealing film layer 131 overlap each other and have the same planar shape and planar area.

[0092] The backing layer 133 and the sealing film layer 131 are bonded together by an adhesive layer to form the sealing film layer 131. The adhesive layer is formed by bonding the lower part of the backing layer 133 to the upper part of the sealing film layer 131 with an adhesive strength of about 500gf / width of 15mm or more.

[0093] The bonding methods include dry lamination bonding using adhesives, extrusion lamination bonding using adhesive resins, or bonding using hot melt adhesives. An appropriate bonding method can be selected from these methods to bond the backing layer 133 and the sealing film layer 131. Furthermore, before bonding, the backing layer 133 is pre-cut with a fully cut pair of scissors or a sewing knife with a dotted line to form an opening guide line 135. Additionally, to make the heat-sealing resin layer 131b of the film or polymer coating easier to tear upon opening, a laser marking is applied to the opening section, making the sealing film layer 131 easier to break and facilitating container opening.

[0094] like Figures 1 to 5 As shown, the container cap 150 of the present invention can open and close the container inlet 111.

[0095] The container cap 150 consists of a main body 151 and a corresponding fastening part 152 formed on the inner side of the main body 151. The container 110 is opened and closed by the fastening part 112 formed on the outer side of the container inlet 111.

[0096] The sealing component 130 of the present invention, as described above, eliminates the traditional opening method mentioned in the background art. The opening component 160 is used so that the container cap 150 is opened while the sealing component 130 is damaged or even cut to open the container inlet 111. The opening component 160 is described in more detail below with reference to the accompanying drawings.

[0097] like Figures 6 to 8 As shown, the opening component 160 of the present invention can be formed on the sealing component 130 and the container cap 150. In this specification, the description assumes that the opening component 160 is formed on the sealing component 130 and the container cap 150 respectively, corresponding to each other. However, when the opening component 160 is formed on the sealing component 130 or the container cap 150, it has the same or similar shape and even function as the opening pull ring and opening hook described later, and opens the inlet of the container by independent action.

[0098] First, the opening component 160 includes an opening pull ring 161 formed on the sealing component 130 and an opening hook 163 formed on the container cap 150.

[0099] In this case, the opening pull ring 161 of the opening component can be formed in the backing layer 133 of the sealing component, such as... Figure 7 and Figure 8 As shown, it can be composed of an outer insertion portion 161a of the opening pull ring 161 located inside the opening pull ring 161 and an inner insertion portion 161b of the opening pull ring 161 located outside the opening pull ring 161. Preferably, the inner insertion portion 161b and the outer insertion portion 161a of the opening pull ring are made in the form of holes, as shown in the figure. This is to facilitate the insertion of the opening hook 163. However, the inner insertion portion 161b and the outer insertion portion 161a of the opening pull ring may not be in the form of holes and may be formed by cutting the backing layer 133. In this case, in order to facilitate the insertion of the opening hook 163 into the outer insertion portion 161a of the opening pull ring, an entry guide portion 161c is formed that protrudes upward from the opening pull ring 161, making the insertion of the opening hook 163 easier.

[0100] When the outer insertion portion 161a of the opening cap and the inner insertion portion 161b of the opening pull ring are configured with holes as shown in the attached figures, preferably, the size of the outer insertion portion 161a of the opening pull ring is larger than the size of the inner insertion portion 161b of the opening pull ring. This is to make it easier to insert the opening hook 163 when opening the container cap 150. That is, when opening the container cap 150, the opening hook 163 needs to be rotated in the opening direction of the container cap 150 to first insert into the outer insertion portion 161a of the opening pull ring. Therefore, preferably, the size of the outer insertion portion 161a of the opening pull ring is larger than the size of the inner insertion portion 161b of the opening pull ring.

[0101] Secondly, such as Figure 6 and Figure 8 As shown, the opening hook 163 of the opening component is integrally formed on the bottom inner side of the body 151 of the container cap. In this case, the opening hook 163 is at least one protrusion formed of an elastic material.

[0102] In the attached diagram, the opening hook 163 is formed by three protrusions. However, the 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 is not formed as an integral part of the container cap 150, but is formed as a separate disc-shaped component that is inserted into the container cap.

[0103] Furthermore, assuming that the opening direction of the container cap 150 is counterclockwise, the opening hook 163 is preferably tilted downward so that the distance between the ends of the opening hook 163 gradually increases from the inner bottom of the container cap 150 in a counterclockwise direction.

[0104] In this case, before the sealing component 130 is opened and the container cap 150 is placed on the container 120, the opening hook 163 is folded in a state where it is pressed against the sealing component 130, but when the container cap 150 is opened, it springs out. For this purpose, the opening hook 163 is formed of plastic or a thin metal material.

[0105] When the container cap 150 is rotated in the opening direction to open the container cap 150, the opening hook 163 also rotates in the opening direction and, while being pressed down, elastically protrudes downwards. In this case, one of the protrusions of the opening hook 163 is inserted into the outer insertion portion 161a of the opening pull ring.

[0106] As described above, when the opening hook 163 is inserted into the outer insertion portion 161a of the opening pull ring and continues to rotate, the opening hook 163 hooks onto the opening pull ring 161. In this state, if the container cap 150 is continued to rotate, the opening hook 163 rises upward and lifts the opening pull ring 161. As mentioned above, when the opening hook 163 lifts the opening pull ring 161 and rotates, the sealing member 130 will be damaged or even cut due to the rotational force of the opening hook 163. In this case, the opening guide line 135 forms a cutting line for the sealing member 130, making it easy for the sealing member 130 to be cut along the opening guide line 135, thereby allowing it to be removed from the upper end face of the container inlet.

[0107] Without the opening guide line 135, the sealing component 130 would be damaged as if torn apart by the opening hook 163, and the opening hook 163 would also be at risk of bending or breaking due to excessive force. Therefore, the opening guide line 135 enables stable cutting of the sealing component 130 and prevents excessive force from being applied to the opening hook 163, making the removal of the sealing component smooth through a stable cutting operation.

[0108] The sealing component 160 configured as described above achieves the cutting of the sealing component 130 based on the sealing pull ring 161 and the sealing hook 163 inserted into the outer insertion part 161a of the sealing pull ring. However, in order to ensure more reliable operation, an inner insertion part 161b and an entry guide part 161c can be formed. The sealing hook 163 can be more flexible by varying its thickness or width, or by varying its thickness and width.

[0109] First, an inner insertion portion 161b is formed on the opening pull ring 161. Preferably, the inner insertion portion 161b is positioned in front of the outer insertion portion 161a, with the opening direction as the reference. That is, the opening hook 163 rotates in the opening direction and first inserts into the outer insertion portion 161a. With continued rotation, the opening hook 163 inserts into the inner insertion portion 161b a second time. Therefore, the opening hook 153 is inserted into both the outer insertion portion 161a and the inner insertion portion 161b, thereby completely hooking the opening pull ring 161. As described above, the outer insertion portion 161a and the inner insertion portion 161b allow the opening pull ring to be completely engaged with the opening hook 163, making the cutting operation of the sealing component 130 smoother.

[0110] Secondly, an entry guide 161c may be formed on the pull ring 161, and the opening hook 163 protrudes upward so that it can be easily inserted into the outer insertion portion 161a of the pull ring first. Therefore, the opening hook 163 can be inserted into the outer insertion portion 161a of the pull ring more easily based on the entry guide 161c, and can be more easily hooked onto the pull ring 161.

[0111] Furthermore, preferably, the opening hook 163 is formed such that the thickness and width are thinner as it approaches the end side.

[0112] This ensures the elasticity of the opening hook 163 and allows for easy insertion into the opening pull ring 161, minimizing the possibility of failure in the connection between the opening hook 163 and the opening pull ring 161. In other words, the closer to the end, the thinner and even wider the opening hook 163, making it easier to deform and ensuring stable operability.

[0113] In this case, when manufacturing the backing layer 133 of the sealing component, the protruding entry guide 161c is formed by thermoforming, which not only makes it easier for the opening hook 163 to enter the opening pull ring 161, but also makes it easier for the opening hook 163 to be hooked onto the opening pull ring 161.

[0114] The container cap and sealing component of the present invention, as described above, with automatic opening function, make the opening component easy to cut or even remove when the container cap is opened, as the opening component is caught by the opening pull ring.

[0115] Figures 9 to 11 Various embodiments based on the form of removing the sealing component from the inlet of the container according to the present invention are shown.

[0116] First, the opening guide line 135 of the present invention is as follows: Figure 7As shown in a, it includes an outer opening guide line 135a connected to the outer end of the opening pull ring 161 and an inner opening guide line 135b connected to the inner end of the opening pull ring 161.

[0117] Figure 9 The outer opening guide line 135a is shown to form a ring along the edge of the backing layer 133. When the container cap 150 and the sealing member 130 are opened, a portion of the sealing member 130 remains on the upper inlet face 111a of the container in the form of a band 136. This is achieved by the outer opening guide line 135a forming a ring on the inner portion of the edge of the backing layer 133. This opening form can be a fully partial opening form where the opening band 136 remains on the upper inlet face 111a of the container. In this case, the sealing strength of the sealing member on the upper inlet face of the container requires a weld seal.

[0118] Figure 10 The outer opening guide line 135a is shown to start from the opening pull ring 161, extending outwards from the outermost part of the sealing member, and crossing the outermost edge. When the container cap 150 and the sealing member 130 are opened, the sealing member 130 is completely removed from the container inlet 111. This opening configuration is a complete opening of the sealing member. In this case, the sealing strength of the sealing member on the upper end face 111a of the container inlet is a peelable seal with an appropriate strength of 200gf / 15mm-1 to 500gf / 15mm.

[0119] Figure 11 This illustrates a case where at least a portion of the outer opening guide line 135a forms a non-circular guide line 135c, which is not circular. In this case, the non-circular guide line 135c does not contact the inner opening guide line 135b and is composed of a straight line or an arc shape, etc. 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 the container cap and sealing component are opened, the cut portion of the sealing component opens in a shape smaller than the upper end face of the container entrance and is not circular. In this case, the sealing component is partially opened, which is a partially opened type.

[0120] Furthermore, preferably, the outer opening guide line 135a and the inner opening guide line 135b of the present invention maintain a certain distance and do not contact each other. This is because if the outer opening guide line 135a and the inner opening guide line 135b were to contact each other, the neck of the opening pull ring 161 would break off. Therefore, the outer opening guide line 135a and the inner opening guide line 135b maintain a certain distance and do not contact each other to prevent the neck of the opening pull ring 161 from breaking off. Preferably, the width of the outer opening guide line 135a is 3 mm or more, and it is formed to an appropriate length inward toward the center of the circle.

[0121] As described above, the opening guide line 135 of the present invention is... Figures 9 to 11 When configured in various ways, the sealing member 130 can be presented in various opening forms. This is effective in that it can present various opening forms of the container inlet 111, taking into account the state of the contents of the container 110 or its use.

[0122] The invention made by the inventor has been specifically described above with reference to the embodiments described above. However, the invention is not limited to the embodiments described above, and various modifications can be made without departing from its spirit.
