Description

Technical Field The present invention relates to the field of product packaging containers, and in particular to a container closing device and a packaging container comprising the closing device, wherein the closing device is used to release the contained and independently sealed materials into the independently sealed materials in the container by operating the closing device, so that various materials are automatically mixed together before opening the packaging container, or a packaging container that achieves an automatic mixing and blending effect.

[0001] The packaging container can be widely used for packaging of beverages, drinking wine, health food, special medical formula food, ordinary food, medicine, medical equipment, sanitary products, cosmetics, daily necessities and other products, and is particularly suitable for sealing and storing products containing liquid materials in the packaging container. The present invention also relates to a packaging composition of the packaging container, an assembly method of the sealing device and its application. Background Art In many applications such as the mixing of different materials, it is necessary to release and mix a material into another material shortly before using the material mixture. It is often impossible or undesirable to store products in a pre-mixed form because when the products are stored as a mixture for a period of time, they may react with each other undesirably or cause the quality of the mixture to deteriorate. A common example is, for example, two or more pharmaceutical components, which have better stability and longer shelf life when not mixed than when mixed.

[0002] Of course, it can also be applied to other liquids, liquid-solid, liquid-liquid mixtures, such as water, alcoholic beverages, other beverages, other solvents or solutions, and oily liquids, etc. For beverages, drinking wine, health foods, special medical formula foods, ordinary foods, medicines, medical devices, sanitary products, cosmetics or daily necessities, etc., during the shelf life of the product, two or more different substances or materials in the product need to be stored separately to make it more conducive to the stability, freshness, function assurance or other quality improvements of the product. The existing technical solutions use two or more different packaging bottles / bags / boxes for independent packaging, and they are recombined for use when in use, which is easy to cause many disadvantages such as inconvenience in carrying, inconvenience in use, and easy to cause secondary pollution.

[0003] International publications WO2007 / 129116 and WO2012 / 175934 disclose a closure device for introducing material in a cover member into a container. The device is provided with a fluid chamber in the cover member. The plug member is driven by the lifting of the shell to open the opening of the fluid chamber, thereby releasing the contents in the cover member. However, the above-mentioned known technical solutions have the following disadvantages: (1) Due to the presence of the plug member with a fixed structure, a large amount of contents will remain in the cover member after the contents are released, resulting in incomplete release of the contents; (2) The fluid chamber requires pressurized gas to release the contents therein, which brings inconvenience to production and filling, and also poses a hidden danger to the safe storage and use of the product in the circulation link; (3) When the container closure device is opened to release the contents therein into the container, the container neck opening is also opened at the same time, and the sealing of the container is destroyed at the same time, which cannot meet the requirements that the contents still need to be sealed after mixing and the mixture needs to be further disposed of; (4) Its structural setting can only be used to seal one type of liquid material, and cannot be achieved for sealing solid materials or multiple materials. Summary of the invention In order to overcome the deficiencies of the prior art, the present invention provides a novel container closure device which has a simple structure, is easy to assemble and fill, has accurately controlled release of contents, can seal and store various materials, the materials can be completely released under the action of a piston, no contents remain in the chamber after the materials are released, and the materials are still in a sealed state after being released into the container, and provides a packaging container including the closure device. The container closure device has independent material sealing and storage functions, and can seal the container to form a packaging container, and independently seal the separately configured materials in the container. The user twists or rotates the packaging container before opening the packaging container, and uses the piston to generate displacement so that the independently sealed contents in the container closure device are completely and thoroughly mixed and blended with the materials in the container.

[0004] The container of the present invention comprises a container neck with an opening and a main body chamber, including but not limited to a packaging bottle, a packaging bag, a packaging can, a packaging cup, a packaging box or a packaging barrel, a packaging cup, and the like.

[0005] The present invention provides a container closing device, which is used to discharge the material in the closing device into the container through the operation of the closing device, and mix and prepare with the material in the main chamber of the container, that is, before opening the packaging container, the operation is performed outside the cover member, and the outlet of the cover member and the outlet of the material cavity are mutually displaced and overlapped by rotating the material cavity, and further by rotating the screwing mechanism, the piston member is displaced to release the material in the material cavity into the container, so as to realize the container closing device for closed storage and release preparation of the material in the material cavity, and in addition, the head end and / or the tail end of the material cavity are provided with a positioning control structure.

[0016] The guiding device arranged on the material cavity barrel comprises a groove-shaped structure or a convex-concave structure arranged on the inner wall of the material cavity barrel. The guiding device can prevent the piston member and the material cavity barrel from rotating relative to each other, and the guiding convex buckle slides in the guiding device to cause the piston member to produce a sliding displacement in the material cavity barrel close to or away from the head end of the material cavity barrel.

The positioning control mechanism at the head end of the cover member is arranged on the inner wall at the head end of the cover barrel structure; the positioning control mechanism at the head end of the material cavity barrel is arranged on the outer wall, inner wall or wall body at the head end of the material cavity barrel;

[0019] For example, a groove-shaped structure provided on the inner wall of the head end of the cover cylinder structure and a convex object provided on the outer wall of the head end of the material cavity cylinder, and the convex object can slide in the groove-shaped structure, playing a role in rotation positioning to prevent eccentric rotation;

[0020] For example, a convex object provided on the inner wall of the head end of the cover cylinder structure and a groove-shaped structure provided on the outer wall of the head end of the material cavity cylinder, and the convex object can slide in the groove-shaped structure, playing a role in rotation positioning to prevent eccentric rotation;

[0021] For example, the retaining buckle in the groove-shaped structure on the inner wall of the head end of the cover tube structure and the convex object on the outer wall of the head end of the material cavity tube, and the retaining buckle in the groove-shaped structure and the convex object can produce an engagement or blocking effect, playing a role in rotation positioning;

[0022] For example, a convex object arranged on the inner wall of the head end of the cover tube structure and a groove-shaped structure arranged on the outer wall of the head end of the material cavity tube, and the convex object and the groove-shaped structure can produce an engagement or blocking effect, playing a role in rotation positioning;

[0023] For example, the convex-concave structure on the inner wall of the head end of the cover tube structure and the convex-concave structure on the outer wall of the head end of the material cavity tube can produce an engagement or blocking effect to play a role in rotational positioning.

[0024] Preferably, the positioning control mechanism on the outer wall of the head end of the material cavity and the inner wall of the head end of the cover cylinder structure fit together to prevent eccentric rotation when the material cavity and the cover cylinder structure rotate relative to each other, thereby affecting the accuracy of the chamber outlet and the cover cylinder structure outlet when they overlap or misalign.

[0025] The positioning control mechanism at the rear end of the cover member and the positioning control mechanism at the rear end of the material cavity barrel include mutually matching convex and concave stopper structures, convex and concave blocking structures, or include mutually matching protruding structures, grooved structures, and the convex and concave structures of the two can rotate with each other to produce an engagement or blocking effect, so as to achieve the positioning control effect when the cover barrel structure and the material cavity barrel rotate with each other, wherein the positioning control mechanism at the rear end of the cover member is arranged on the cover surrounding structure, or the positioning control mechanism at the rear end of the cover member is arranged at the rear end of the cover barrel structure, for example, including being arranged on the inner wall, outer wall or wall body of the rear end of the cover barrel structure; the positioning control mechanism at the rear end of the material cavity barrel is arranged on the outer wall of the rear end of the material cavity barrel;

[0026] For example, the convex-concave structure arranged on the rear end of the cover tube structure and the convex-concave structure arranged on the rear end of the material cavity tube can produce an engagement or blocking effect, and play a role in rotation positioning;

[0027] For example, the convex-concave structure arranged on the cover surrounding structure and the convex-concave structure arranged at the rear end of the material cavity can produce an engagement or blocking effect, thereby playing a role in rotational positioning.

[0028] The positioning control mechanism of the cover member and the material cavity tube described in the present invention has a mutually matching convex and concave structure, including mutually matching convex and concave stopper structures, convex and concave blocking structures, protrusion structures, groove structures, etc.; the positioning control mechanism set at the head end or / and tail end of the cover member described in the present invention includes the above-mentioned structures that match each other, and the positioning control mechanism set at the head end or / and tail end of the material cavity tube includes the above-mentioned structures that match each other, wherein mutual matching refers to being able to engage with each other, or properly engage with each other, thereby generating mutual contact, blocking and other effects, and having a mutual matching effect or matching state; in addition, the blocking effect includes two concepts of blocking or hindering, blocking means being blocked and stopping relative movement, and hindering means being blocked, and the relative movement may be stopped, or it may not be blocked, and relative movement can still occur after breaking through the blocking effect.

[0029] On the other hand, preferably, the positioning control mechanism at the head end of the cover member and the positioning control mechanism at the head end of the material cavity include a stop mechanism or a locking mechanism that can engage with each other; the positioning control mechanism at the tail end of the cover member and the positioning control mechanism at the tail end of the material cavity include a stop mechanism or a locking mechanism that can engage with each other;

[0030] Wherein, the stop mechanism is arranged at any contacting position between the cover member and the head end or / and the tail end of the material cavity, and the stop mechanism is engaged when the material cavity rotates to a predetermined position relative to the cover structure to prevent the material cavity and the cover structure from further relative rotation, and the predetermined position includes and is preferably a position where the cover outlet and the chamber outlet are mutually misaligned or overlapped, and the prevention of further relative rotation of the cover structure and the material cavity is preferably that the cover structure and the material cavity block each other and cannot further rotate relative to each other;

[0031] Wherein, the locking mechanism is arranged at any contacting position between the head end of the cover barrel structure and the head end of the material chamber barrel; or, the locking mechanism is arranged at any contacting position between the tail end of the cover member and the tail end of the material chamber barrel. The locking mechanism is engaged when the material chamber barrel rotates to a predetermined position relative to the cover barrel structure to prevent further relative rotation of the material chamber barrel and the cover barrel structure. The predetermined position includes and is preferably a position where the cover barrel outlet and the chamber outlet are mutually misaligned or overlapped. The further relative rotation of the material chamber barrel and the cover barrel structure is prevented, preferably, there is a hindering effect between the material chamber barrel and the cover barrel structure. Increasing the mutual rotation force can make the material chamber barrel and the cover barrel structure rotate relative to each other, but cannot be easily rotated.

[0032] Preferably, the stop mechanism or locking mechanism of the positioning control mechanism of the cover member and the material cavity can be one or more structures that match each other, and it is particularly preferred to be a setting of two structures distributed in symmetrical positions. For example, two convex-concave stopper structures, convex-concave blocking structures or convex-concave groove structures arranged at mutually symmetrical positions at the head end of the cover member match with two convex-concave stopper structures, convex-concave blocking structures or convex-concave groove structures arranged at mutually symmetrical positions at the head end of the material cavity, and can rotate with each other to produce an engagement or blocking effect. For example, two convex-concave stopper structures, convex-concave blocking structures or convex-concave groove structures arranged at mutually symmetrical positions at the tail end of the cover member match with two convex-concave stopper structures, convex-concave blocking structures or convex-concave groove structures arranged at mutually symmetrical positions at the tail end of the material cavity, and can rotate with each other to produce an engagement or blocking effect.

[0033] The container closure can be assembled and filled and sealed with the target material before being installed on the neck of the container.

[0034] When the material in the above-mentioned container closing device is in a storage state, the cover tube outlet and the chamber outlet are misaligned with each other, and the cover tube structure is sleeved on the material cavity tube by a buckle or a thread and tightly closed together, so that the material in the material cavity tube is in an independently sealed state; the container closing device is installed on the neck of the container to form a combined packaging container. Before opening the packaging container, it is only necessary to twist the material cavity tube or rotate the screwing mechanism to make the chamber outlet coincide with the cover tube outlet, and then the screwing mechanism is rotated to make the threaded buckle slide in the threaded track, and under the guiding action of the guide convex buckle sliding in the guide device, the piston member is caused to produce a sliding displacement close to the head end of the material cavity tube in the material cavity tube, and the piston squeezes the material in the material cavity tube and releases it, and mixes it with the material in the container, and then the neck opening of the container is opened for use; before opening the packaging container, only the screwing operation of the screwing mechanism is required to completely mix and blend the material in the material cavity tube with the material in the container, thereby achieving the purpose of mixing and blending the materials before use.

[0035] The cover tube structure is sleeved on the outer wall of the material cavity, and the head end of the cover tube structure can be tightly fitted with the head end of the material cavity, or the inner wall portion of the cover tube structure around the cover tube outlet can be tightly fitted with the outer wall portion of the head end of the material cavity, or the outer wall portion of the material cavity around the chamber outlet can be tightly fitted with the inner wall portion of the head end of the cover tube structure, so as to ensure the sealing of the chamber outlet and the cover tube outlet when they are misaligned, and to ensure that the material cannot leak into the gap between the cover tube structure and the material cavity when their outlets overlap. For example, as needed, a sealing plug or a sealing gasket is provided at the position where the head end of the cover tube structure and the head end of the material cavity contact each other, so as to strengthen the sealing performance between the two when the cover tube structure is sleeved on the outer wall of the material cavity, and the sealing plug or the sealing gasket is usually made of rubber material, preferably silicone, butyl rubber or thermoplastic rubber;

[0036] The sealing plug or sealing gasket includes a method of using injection molding to coat the rubber material on the inner wall of the head end of the cover tube structure; or a method of using injection molding to coat the rubber material on the outer wall of the head end of the material cavity; or a method of dripping glue to apply a layer of rubber pad on the inner wall of the head end of the cover tube structure; or a method of dripping glue to apply a layer of rubber pad on the outer wall of the head end of the material cavity; the sealing plug or sealing gasket can also be made into a separate rubber material accessory, and then the accessory is installed on the inner wall of the head end of the cover tube structure, or the accessory is installed on the outer wall of the head end of the material cavity, but no matter which method is used, the cover tube outlet must be unobstructed, and the chamber outlet must also be unobstructed. Preferably, a sealing gasket or a sealing plug is provided on the outer wall of the head end of the material cavity barrel and around the chamber outlet, or a sealing gasket or a sealing plug is provided on the inner wall of the head end of the cover barrel structure and around the cover barrel outlet, so as to ensure the sealing of the chamber outlet. For example, the sealing gasket or the sealing plug is achieved by fixing a rubber material at the above-mentioned position of one of the components by means of glue dripping or injection molding, or preferably by installing the sealing gasket or the sealing plug at the above-mentioned position of one of the components. The sealing gasket or the sealing plug is usually made of a rubber material, preferably silicone, butyl rubber or thermoplastic rubber.

[0037] It should be explained that regarding the concepts of the head end and tail end of components such as the material chamber, cover member, cover tube structure, cover surrounding structure, piston member or screwing mechanism, their head end refers to the end closest to the material in the container after they are installed on the container, and their other end is called the tail end.

[0038] Preferably, the inner space of the material chamber generally has a chamber structure for accommodating materials.

[0039] Furthermore, the internal space of the material cavity of the container closure device of the present invention has two or more chamber structures, so that at least two materials can be sealed, stored, and released independently in the container closure device, so as to meet the requirements of stability or comprehensive blending of multiple materials, wherein the internal space of the material cavity or the internal space of the cover cylinder structure has at least two chamber structures, and each chamber structure has a separate piston member. For example, the internal space of the material cavity has two or more cylindrical inner cylinder structures, or the internal space of the cover cylinder structure has two or more cylindrical chamber structures, or the internal space of the material cavity has two chamber structures in the form of annular sleeves, one of which is an annular structure and the other is a cylindrical structure.

[0040] Preferably, the internal space of the material cavity or the internal space of the cover cylinder structure includes two chamber structures, and each chamber structure has a respective independent piston member to respectively accommodate two different materials, and the head end of the material cavity is provided with the outlet of the respective chamber, and the head end of the cover cylinder structure is also provided with at least one cover cylinder outlet; preferably, the internal space of the material cavity has three chamber structures, and each chamber structure has a respective independent piston member and a screwing mechanism to respectively accommodate three different materials, and the head end of the material cavity is provided with the outlet of the respective chamber, and the head end of the cover cylinder structure is also provided with at least one cover cylinder outlet.

[0041] The number of outlets of each chamber of the material cavity is at least one, preferably each chamber has one outlet, and the number of outlets of the cover tube structure is at least one, and the number of outlets of the cover tube structure can be the same as or different from the number of outlets of all chambers. The effect and significance of such a setting is that the chamber outlet and the outlet of the cover tube structure can overlap and stagger at different rotation angles and different positions, which is conducive to controlling the order of material release in each chamber in the rotation angle or range of the material cavity before opening the packaging container, and can realize the diversification of material release, so that the allocation of each material is more accurate and scientific. For example, when the cover tube structure has only one outlet, when the cover tube structure and the material cavity rotate with each other, the outlets of each chamber of the material cavity can overlap with the outlet on the cover tube structure in turn, so that the materials in each chamber are released in turn; for another example, when the number of outlets of the cover tube structure is the same as the number of outlets of all chambers, when the cover tube structure and the material cavity rotate with each other, the chamber outlet can overlap with the outlet on the cover tube structure at the same time or with a delay, so that the materials in the chamber are released at the same time or with a delay.

[0042] The material contained in the material cavity or chamber is preferably a liquid material, a mixture of solid and liquid or a slurry, or a solid material, etc. The size of the cover tube outlet and the chamber outlet can be set according to the state of the released material. For liquid materials with good fluidity, the cover tube outlet and the cavity tube or chamber outlet or their channels can be large or small. For materials with poor fluidity, such as high-viscosity liquid materials, slurries, solid powders, solid particles, pills, solid flakes or blocks, the cover tube outlet and the cavity tube or chamber outlet should be set larger to facilitate the smooth release of the material. For example, the diameter of the cover tube outlet is 0.5mm to 25mm, and the diameter of the chamber outlet is 0.5mm to 25mm. Preferably, the diameter of the cover tube outlet is 0.6mm to 8mm, and the diameter of the chamber outlet is 0.6mm to 8mm. For example, the diameter of the cover tube outlet or the chamber outlet is 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm or 8mm.

[0043] If necessary, a non-smooth outer surface is provided on the outer wall of the screwing mechanism, for example, it is provided with convex and concave textures, carved textures, a frosted outer surface, convex and concave lines or convex and concave ribs, etc.

[0044] Furthermore, the container closure device of the present invention has an anti-theft opening structure to prevent the material cavity from being accidentally rotated. Preferably, the portion where the material cavity is close to or in contact with the cover member is provided with an anti-theft opening structure, or the portion where the screwing mechanism is close to or in contact with the material cavity is provided with an anti-theft opening structure, or the portion where the screwing mechanism is close to or in contact with the cover member is provided with an anti-theft opening structure, and the anti-theft opening structure has the function of providing anti-theft protection for the container closure device and preventing it from being accidentally opened. For example, a tearable connection ring with a serrated structure is arranged at the tail end of the material cavity tube, and the tearable connection ring is connected to the tail end of the material cavity tube by contact connection or micro-connection, and forms an integral component with the material cavity tube; and a serrated structure is also arranged on the cover member, and the serrated structure at the tail end of the material cavity tube and the serrated structure on the cover member can be engaged with each other. When the material cavity tube rotates, the serrated structure on the cover member blocks the serrated structure at the tail end of the material cavity tube, and the tearable connection ring is blocked, and its point-connected contacts or micro-connections can be broken, and the tearable connection ring is separated from the material cavity tube, which plays an anti-theft opening role. The serrated structure on the cover member is located at the rear end of the cover tube structure, or on the cover surrounding structure. Preferably, the serrated structure enables the tearable connecting ring to slide through when it rotates in one direction relative to the cover member, but is blocked when it rotates in the opposite direction. This arrangement can match each other when engaged with each other, and is usually made of plastic, rubber, plastic or metal materials to achieve that the tearable connecting ring can only rotate in one direction, but is blocked when it rotates in the opposite direction, thereby allowing the point-connected contacts or micro-connections to break.

[0045] Or, for example, a tearable connection ring with a serrated structure is provided on the screwing mechanism, and the tearable connection ring is connected to the screwing mechanism by means of contact connection or micro-connection, and forms an integral component with the screwing mechanism; and a serrated structure is also provided at the tail end of the material chamber tube, and the serrated structure on the screwing mechanism and the serrated structure at the tail end of the material chamber tube can be engaged with each other. When the screwing mechanism rotates, the serrated structure at the tail end of the material chamber tube blocks the serrated structure on the screwing mechanism, and the tearable connection ring is blocked, and its point-connected contacts or micro-connections can be broken, and the tearable connection ring is separated from the screwing mechanism, thereby playing an anti-theft opening role.

[0046] Or, for example, a tearable connection ring with a serrated structure is provided on the screwing mechanism, and the tearable connection ring is connected to the screwing mechanism by means of contact connection or micro-connection, and forms an integral part with the screwing mechanism; and a serrated structure is also provided on the cover member, and the serrated structure on the screwing mechanism and the serrated structure on the cover member can be engaged with each other. When the screwing mechanism rotates, the serrated structure on the cover member blocks the serrated structure on the screwing mechanism, and the tearable connection ring is blocked, and its point-connected contacts or micro-connections can be broken, so that the tearable connection ring is separated from the screwing mechanism, thereby preventing the opening from being theft. The serrated structure on the cover member is located at the rear end of the cover tube structure, or on the cover surrounding structure. Preferably, the serrated structure enables the tearable connecting ring to slide through when it rotates in one direction relative to the material cavity or the screwing mechanism, but is blocked when it rotates in the opposite direction. This arrangement can match each other when engaged with each other, and is usually made of plastic, rubber, plastic or metal materials to achieve that the tearable connecting ring can only rotate in one direction, but is blocked when it rotates in the opposite direction, thereby allowing the point-connected contacts or micro-connections to break.

[0047] Preferably, the screwing mechanism of the container closure device of the present invention protrudes from the material cavity tube or the cover surrounding structure, and the overall appearance of the container closure device after assembly presents a convex shape. The advantage and importance of this appearance shape lies in that it is conducive to the mutual connection and stability of the cover tube structure and the material cavity tube; it is also conducive to expanding the volume of the material cavity tube outward to facilitate accommodating more materials, and is more conducive to the rotation operation of the screwing mechanism, as well as satisfying the mutual connection and sealing assembly operations of the screwing mechanism and the cover member, and the screwing mechanism and the material cavity tube.

[0048] Further, as needed, a circle of easy-to-tear connecting ring with anti-theft opening function can be set at the front end of the outer periphery of the cover surrounding structure. The easy-to-tear connecting ring is connected to the cover surrounding structure by contact connection or micro-connection, and forms an integral component with the cover surrounding structure. When the container closing device is installed on the container neck and the container needs to be opened and the cover surrounding structure is twisted or rotated, the easy-to-tear connecting ring is blocked by the container neck, and its point-connected contacts or micro-connections are broken, so that the easy-to-tear connecting ring is separated from the cover surrounding structure, thereby playing a role in anti-theft opening.

[0049] Further, as needed, a sealing gasket can be provided on the inner wall of the cover surrounding structure in contact with the opening of the container to ensure the sealing between the opening of the container and the cover surrounding structure. The preferred sealing gasket is a gasket of rubber material, and the most preferred is a silicone gasket. Alternatively, a layer of rubber gasket is preferably applied to the inner wall of the top of the cover surrounding structure by a glue dripping method.

[0050] The various parts, components, mechanisms, devices, settings, etc. of the container closure device or packaging container described in the present invention can be obtained by assembling, connecting, fixing, bonding or welding of individual parts, preferably an assembly or combination of the various parts described in the present invention, or an assembly or combination that can be assembled.

When the container closing device is installed on the neck of the container 1 and the container needs to be opened and the cover surrounding structure 201 needs to be twisted or rotated, the tearable connecting ring 210 is broken at the point-connected contacts due to the anti-theft opening block 102 on the neck of the container, and the tearable connecting ring 210 is separated from the cover surrounding structure 201, thereby playing an anti-theft opening role.

[0147] The piston member 4 comprises a piston 401 and a piston support 402, wherein the piston 401 is mounted at the head end of the piston support 402, a piston stop 405 is provided at the head end of the piston support 402 to strengthen the fixation of the piston 401 at the head end of the piston support 402, and a threaded buckle 403 and a guide convex buckle 404 are provided on the piston support 402;

[0148] The screwing mechanism 5 has a cover-like structure 501, and a screwing mechanism buckle 504 and a driving convex buckle 505 are arranged on the inner wall of the cover-like structure 501. A cylindrical structure 502 is arranged on the inner wall of the top of the cover-like structure 501, and a threaded track 503 is arranged on the inner wall of the cylindrical structure 502. Furthermore, the cover-like structure 501 is provided with an easy-to-tear connecting ring 506, and the easy-to-tear connecting ring 506 is connected to the cover-like structure 501 by contact connection or micro-connection. A serrated structure 507 is arranged on the inner wall of the easy-to-tear connecting ring 506.

[0149] The cover cylinder structure 202 is sleeved on the outer wall of the material cavity cylinder 3, and the cover cylinder structure 202 and the material cavity cylinder 3 are connected by the buckle 205 and the buckle 303. The positioning flange 310 at the head end of the material cavity cylinder is in the positioning groove 207 at the head end of the cover cylinder structure. The cover cylinder structure 202 and the material cavity cylinder 3 can rotate relative to each other, so that the positioning flange 310 slides in the positioning groove 207, and the positioning stop buckle 308 at the tail end of the material cavity cylinder is engaged with the positioning stop buckle 206 at the tail end of the cover cylinder structure, and the positioning stop buckle 308 is in the cover cylinder structure. The positioning stop buckle 206 and the positioning locking buckle 208 at the tail end can ensure that the cover tube structure 202 and the material chamber 3 do not rotate eccentrically when they rotate relative to each other, and ensure the accurate positioning, stopping and locking control operation of the cover tube outlet 203 and the chamber outlet 302 when they are misaligned or overlapped with each other. In addition, the locking structure has the function of preventing the accidental release of materials in storage, transportation and other states, or when the cover tube outlet overlaps with the chamber outlet, the locking mechanism can maintain the stability of the outlet overlap, and also facilitates the user to control the hand feel during the screwing operation;

[0150] The piston 401 at the head end of the piston member 4 is in the material cavity 3, and the guide protrusion 404 is in the guide groove 304 provided on the material cavity and can slide in the guide groove 304;

[0151] The threaded track 503 provided on the screwing mechanism 5 is connected to the threaded buckle 403 provided on the piston support 402, and the threaded buckle 403 is in the threaded track 503 and can slide in the threaded track 503;

[0152] The screwing mechanism buckle 504 arranged on the inner wall of the cover-like structure 501 of the screwing mechanism 5 is connected to the buckle 211 at the rear end of the cover member. The screwing mechanism 5 can be installed on the cover member 2 through the mutual connection of the buckles, and the screwing mechanism 5 and the cover member 2 can rotate with each other. The mutual rotation of the screwing mechanism 5 and the cover member 2 can realize the sliding displacement of the threaded buckle 403 in the threaded track 503, so that the guide protrusion 404 slides in the guide groove 304, and further realizes the sliding displacement of the piston member 4 in the material cavity 3 close to the head end of the material cavity 3, that is, the material in the material cavity 3 can be squeezed and released by the piston action.

[0153] On the other hand, the serrated structure 209 arranged on the outer wall of the rear end of the cover tube structure 202 and the serrated structure 507 arranged on the inner wall of the easy-to-tear connecting ring 506 arranged on the screwing mechanism 5 are matched and engaged with each other. The setting of the serrated structure enables the serrated structure 209 and the serrated structure 507 to generate a mutual blocking force when the screwing mechanism 5 rotates in one direction, thereby breaking the connecting contact between the easy-to-tear connecting ring 506 and the screwing mechanism 5, thereby playing a role in preventing theft and opening.

[0154] When the screwing mechanism 5 is rotated, the driving convex buckle 505 provided on the screwing mechanism 5 can engage with the driving convex buckle 312 provided at the tail end of the material cavity tube 3, thereby generating an obstruction effect, so that the screwing mechanism 5 can drive the material cavity tube 3 to rotate when it rotates, so as to achieve the overlap of the chamber outlet 302 of the material cavity tube 3 and the cover tube outlet 203, so that the chamber outlet 302 is opened, and at this time, the positioning stop buckle 308 is between the positioning stop buckle 206 and the positioning locking buckle 208 at the tail end of the cover tube structure, and the material cavity tube 3 is blocked and cannot be further rotated. When the rotational force of the screwing mechanism 5 is appropriately increased, the driving convex buckle 505 can slide through the surface of the driving convex buckle 312, and finally the screwing mechanism 5 opens the chamber outlet 302 during the screwing process, and further rotates to cause the piston member 4 to generate a sliding displacement in the material cavity tube 3 close to the head end of the material cavity tube 3, and the material in the material cavity tube 3 is squeezed and released by the piston action.

[0155] If necessary, convex and concave patterns are provided on the outer wall of the cover-like structure 501 of the screwing mechanism 5 to facilitate its rotating and screwing operation and neat appearance; if necessary, convex and concave patterns or convex and concave ribs are provided on the outer wall of the cover surrounding structure 201 to facilitate its rotating and screwing operation and neat appearance.

[0156] When the material in the above-mentioned container closure device is in a storage state, the chamber outlet 302 and the cover tube outlet 203 are in a mutually displaced position, the material is in the internal space of the material chamber 3 and is in an independently sealed state. Before opening the packaging container, by twisting the screwing mechanism 5, the driving convex buckle 505 provided on the screwing mechanism 5 engages with the driving convex buckle 312 provided at the tail end of the material chamber 3, which can drive the material chamber 3 to rotate. Under the action of the positioning control structure provided at the head and tail ends of the cover member 2 and the material chamber 3, the chamber outlet 302 of the material chamber 3 is overlapped with the cover tube outlet 203, so that the chamber outlet 302 is opened, and the connection contact point between the easy-to-tear connecting ring 506 and the screwing mechanism 5 is broken, which plays a role in anti-theft opening; further twisting the screwing mechanism 5 causes the piston member 4 to produce a sliding displacement in the material chamber 3 close to the head end of the material chamber 3, and the material in the material chamber 3 is squeezed and released by the piston action, and mixed with the material in the main chamber 103 of the container. Before opening the packaging container, only a twisting operation is required to accurately, completely and conveniently mix the material in the container closing device with the material in the container 1, and then the cover member 2 is further twisted, the container 1 is opened and the prepared mixed material is used, thereby achieving the purpose of mixing and preparing the materials before use.

The tearable connecting ring 210 is connected to the cover surrounding structure 201 by contact connection or micro-connection, and forms an integral component with the cover surrounding structure 201. The characteristic is that the contact connection or micro-connection makes the connecting ring easy to be torn. When the container closing device is installed on the neck of the container 1 and the container needs to be opened and the cover surrounding structure 201 needs to be twisted or rotated, the tearable connecting ring 210 is broken at the point-connected contacts due to the anti-theft opening block 102 on the neck of the container, and the tearable connecting ring 210 is separated from the cover surrounding structure 201, thereby playing an anti-theft opening role.

[0159] The packaging container can be used to package two different independently sealed materials, wherein the main chamber 103 of the container 1 accommodates the first material, and the material cavity 3 accommodates the second material. The packaging container has the functions of independent material storage and instant preparation as described in the present invention, and solves the shortcomings of existing container closing devices and packaging containers.

Before opening the packaging container, the material chamber tube 3 is first twisted to break the connection point between the tearable connection ring and the tube surrounding structure, and under the action of the positioning control structure set at the head and tail ends of the container closure device, the two chamber outlets and their corresponding cover tube outlets are in a properly overlapping position, and the two chamber outlets are opened at the same time; further, by rotating the screwing mechanism 52, the material in its inner tube structure is squeezed and released through the action of the piston, and mixed with the material in the main chamber 103 of the container. Similarly, the other tube surrounding structure is twisted to release the material in the other inner tube structure. It is achieved that before opening the packaging container, only the screwing operation is required to make the two materials in the container closure device accurately, completely and conveniently mixed and blended with the material in the container 1 in turn, and then the cover member 2 is further screwed, and the container 1 is opened to use the prepared mixed material, thereby achieving the purpose of mixing and blending the materials before use.

[0184] If necessary, a sealing plug or a sealing gasket is provided at the position where the head end of the cover tube structure 202 contacts the head end of the material cavity tube 3 to enhance the sealing performance therebetween. The sealing plug or the sealing gasket is usually made of a rubber material, preferably silicone, butyl rubber or thermoplastic rubber. A sealing gasket 311 is preferably provided on the outer wall of the head end of the material cavity tube 3 and around the chamber outlet. The sealing gasket 311 is preferably implemented by fixing the rubber material on the outer wall of the head end of the material cavity tube 3 by glue dripping or injection molding.

[0185] If necessary, a tearable connecting ring 210 is provided at the head end of the periphery of the cover surrounding structure 201. The tearable connecting ring 210 is connected to the cover surrounding structure 201 by contact connection or micro-connection, and forms an integral component with the cover surrounding structure 201. The characteristic is that the contact connection or micro-connection makes the connecting ring easy to be torn. When the container closing device is installed on the neck of the container 1 and the container needs to be opened and the cover surrounding structure 201 needs to be twisted or rotated, the tearable connecting ring 210 is broken at the point-connected contacts due to the anti-theft opening block 102 on the neck of the container, and the tearable connecting ring 210 is separated from the cover surrounding structure 201, thereby playing an anti-theft opening role.

[0186] Furthermore, the dual-chamber container closing device is installed on a container 1 with an open neck to form a packaging container, and the container includes but is not limited to a packaging bottle, packaging bag, packaging can, packaging cup, packaging box or packaging barrel with an open neck, and the neck of the container 1 is provided with a thread 101 or a buckle, and the thread or buckle can be connected and sealed with the thread or buckle provided on the inner wall of the side enclosure of the cover structure; or, the cover structure of the container closing device and the neck of the container are sealed by bonding or welding, for example, the outer wall of the side enclosure of the cover structure and the neck of the packaging bag container are sealed by bonding or welding, preferably by heating or high-frequency hot melting.

[0187] The packaging container can be used to package three different independently sealed materials, wherein the main chamber 103 of the container 1 accommodates the first material, and the inner tube structure 34 and the inner tube structure 35 respectively accommodate the second material and the third material. The packaging container has the function of independent storage and instant preparation of materials as described in the present invention, which solves the shortcomings of existing container closing devices and packaging containers.

[0196] The cover cylinder structure 202 is sleeved on the outer wall of the material cavity cylinder 3, and the cover cylinder structure 202 and the material cavity cylinder 3 are connected by the buckle 205 and the buckle 303. The positioning flange 310 at the head end of the material cavity cylinder is in the positioning groove 207 at the head end of the cover cylinder structure. The cover cylinder structure 202 and the material cavity cylinder 3 can rotate relative to each other, so that the positioning flange 310 slides in the positioning groove 207, so that the positioning stop buckle 308 at the tail end of the material cavity cylinder and the positioning stop buckle 206 at the tail end of the cover cylinder structure are engaged with each other, and the positioning stop buckle 308 is in the positioning stop buckle 206 at the tail end of the cover cylinder structure. 06 and the positioning locking buckle 208, it can ensure that the cover barrel structure 202 and the material chamber barrel 3 do not rotate eccentrically when they rotate relative to each other, and ensure the accurate positioning, stopping, and locking control operations of the cover barrel outlet 2201 and the chamber outlet 3602, and the cover barrel outlet 2301 and the chamber outlet 302 when they are misaligned or overlapped with each other, and the locking structure has the function of preventing the accidental release of materials in storage, transportation, etc., or when the cover barrel outlet overlaps with the chamber outlet, the locking mechanism can maintain the stability of the outlet overlap, and it is also convenient for the user to control the hand feel during the screwing operation;

[0197] The piston 4401 at the head end of the piston member 44 is in the annular chamber structure of the material chamber 3, and the guide convex buckle 4404 is in the guide groove 304 provided on the material chamber and can slide in the guide groove 304; and the piston 4301 at the head end of the piston member 43 is in the cylindrical chamber structure of the material chamber 3, and the guide convex buckle 4304 is in the guide groove 3604 provided on the inner cylinder 36 of the material chamber and can slide in the guide groove 3604;
