Description

Technical Field The present invention relates to the field of product packaging containers, and in particular to a sealing device and a packaging container comprising the sealing device, wherein the sealing device is used to release separately contained and independently sealed materials into independently sealed materials in a container through operation of the sealing device, so that various materials can be mixed together through operation outside the lid of the container before opening the packaging container, thereby achieving an automatic mixing 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. The present invention also relates to a packaging composition of the packaging container, a method for assembling the sealing device and its application. Background Art In many applications such as the mixing of different materials, it is necessary to discharge and mix the materials into other materials shortly before using the material mixture. It is not possible or desirable 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 the quality of the mixture may deteriorate. A common example is, for example, two or more pharmaceutical components, which have a longer stability and shelf life when not mixed than when mixed.

[0002] Of course, it can also be applied to other liquids or mixtures of liquids, solids and liquids, such as water, alcoholic beverages, other beverages, other solvents or solutions, and oily liquids, etc. For products such as beverages, drinking wine, health foods, special medical formula foods, ordinary foods, medicines, medical devices, sanitary products, cosmetics or daily necessities, 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] Chinese patent publications CN101479165A and CN103648923A disclose a closure device for introducing materials in a cover member into a container, wherein a fluid chamber is provided in the cover member, and a plug member is driven by lifting 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: the structure is relatively complex and the degree of industrial assembly is low; the structural setting of the cover member can only be used to seal one liquid material, and cannot be achieved for sealing solid materials or multiple materials; the coordination with the packaging container in the operation of adding a cover and sealing is poor; there are serious deficiencies in the coordination with the packaging container in repeated use of rotating unsealing, and the sequential coordination of the twisting displacement of the cover member and the release of materials.

[0004] International publication WO2004 / 035418 and Chinese patent publication number CN1708438A disclose a two-compartment beverage bottle, which includes an outer bottle and a twist-type inner container, the inner container is filled with a first liquid, and the space between the outer container and the inner container is filled with a second liquid. When the contents are drunk directly from the beverage bottle, each sip contains the first and second liquids in substantially the same proportion; however, the two-compartment beverage bottle can only be used for packaging of liquid substances, and lacks the function of automatic mixing and blending.

[0005] Chinese patent publication number CN101433498A discloses a dual-chamber medicine dispensing bottle, in which a subsidiary bottle body isolated from the main bottle body is provided in the bottle cap on one of the outlets, a positioning device is provided between the subsidiary bottle body and the bottle cap, and a cutting and opening device is provided at the bottom of the bottle cap. When in use, the patient rotates the subsidiary bottle body, causing the serrated protrusions to break and cut the subsidiary bottle body, and opens the bottom of the bottle cap to make the medicine flow into the main bottle body, thereby achieving mixing of the medicine liquid; however, the dual-chamber medicine dispensing bottle mixes the medicine liquid after each independent seal is broken and opened, which is a passive type, and lacks the functions of automatic mixing and rapid preparation when the bottle body is opened or the bottle cap is twisted.

[0006] On the other hand, the prior art solutions cannot implement the intermediate operation step of pre-mixing before mixing and preparing the materials, which is disadvantageous for the mixing and preparation of drugs, especially the mixing and preparation of injectable drugs. Summary of the invention In order to overcome the shortcomings of the prior art, the present invention provides a new container closure device with a simple structure, easy operation, accurate control, and convenient carrying and storage, and a packaging container including the closure device. The container closure device or packaging container not only has the overall commodity sealing property, but also can independently seal two or more materials separately configured in the packaging container. The user operates before opening the packaging container, and the independently sealed contents in the packaging container can be accurately mixed and blended together, or pre-mixed or pre-dissolved before blending together; not only the stability, freshness, functional quality or other quality of the product is guaranteed, but also the user can intuitively feel the special properties of the product contents, and can also let the user get pleasure from the process of automatic product blending. The present invention also relates to the packaging composition, assembly method and application of the packaging container.

[0007] The packaging container of the present invention includes a packaging container with an open container neck, 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.

[0008] The present invention provides a container closing device, which is used to release one or more materials in the closing device into the container through the operation of the closing device, and mix and formulate with the materials in the main chamber of the container, that is, the operation is performed on the outside of the cover member, and the outlet mechanism for releasing the materials is displaced and overlapped with each other, and under the action of the piston in the material cavity, a technical solution for sealing and storing or releasing and formulating the materials in the material cavity before opening the packaging container is realized. Moreover, after the container closing device mixes and formulates the materials in its material cavity with the materials in the main chamber of the container, the mixed materials in the packaging container can still be in a sealed state.

[0009] The present invention adopts the following technical solutions.

[0010] A container closing device, comprising a cover member, a material chamber, a piston member, and a control member, wherein the cover member has a cover surrounding structure and a cover tube structure, wherein the cover surrounding structure and the cover tube structure are connected to each other and are in an annular sleeve-shaped structure, and a thread or buckle that can be connected and sealed with the neck of the container is arranged on the inner wall of the side surrounding of the cover surrounding structure, or the side surrounding of the cover surrounding structure can be sealed with the neck of the container by bonding or welding, for example, preferably, the outer wall of the side surrounding of the cover surrounding structure is sealed with the neck of the packaging bag container by bonding or welding;

[0012] The cover tube structure is sleeved on the outer wall of the material cavity tube, and the cover tube structure and the material cavity tube can rotate with each other. The mutual rotation of the cover tube structure and the material cavity tube can realize that the outlet of the cover tube structure and the outlet of the material cavity tube are mutually misaligned or overlapped. When their outlets are mutually misaligned, the outlet of the material cavity tube is sealed, and when their outlets overlap with each other, the outlet of the material cavity tube can be opened;

[0013] The cover tube structure and the material cavity tube are connected to each other through threads or buckles, and the head end of the cover tube structure is tightly fitted with the head end of the material cavity tube;

[0017] The piston and the piston support member may be made of the same plastic material, for example, the piston is made into a plastic member that fits tightly against the inner wall of the cylinder in which it is located, and is connected to the piston support member or assembled on the piston support member to form a piston member;

[0018] Alternatively, the piston may be made of a separate polymer material or rubber material and mounted on one end of the piston support; or the piston may be formed by encapsulating the rubber material on one end of the piston support using an injection molding method. The piston support is preferably a connecting rod, tubular or columnar structure.

[0019] The control member is connected to the piston support, and the control member can act on the piston support to make the piston slide in the material chamber; on the one hand, the control member and the cover cylinder structure can rotate with each other, and the control member has a setting that can drive the material chamber to rotate when it rotates; or, on the other hand, the control member and the cover cylinder structure can rotate with each other, and the control member has a setting that can drive the piston member to rotate when it rotates. Preferably, the control member is a cylindrical structure. More preferably, mutually matching driving buckles are provided on the outer wall of the control member and the inner wall of the material cavity, or mutually matching driving buckles are provided on the outer wall of the control member and the inner wall of the fixed inner cylinder of the material cavity, or mutually matching driving buckles are provided on the inner wall of the control member and the outer wall of the material cavity, or mutually matching driving buckles are provided on the inner wall of the control member and the outer wall of the fixed inner cylinder of the material cavity, or mutually matching driving buckles are provided on the piston support and the inner wall of the material cavity, or mutually matching driving buckles are provided on the piston support and the inner wall of the fixed inner cylinder of the material cavity; the driving buckles include a structural setting in the form of a protrusion or a groove, which includes but is not limited to a strip, columnar, sheet or groove-shaped setting.

[0020] The cover tube structure and the material cavity tube are connected to each other through threads or buckles, and the head end of the cover tube structure is tightly fitted with the head end of the material cavity tube;

[0021] The head end of the cover tube structure is tightly fitted with the head end of the material cavity tube, including the inner wall portion of the head end of the cover tube structure and the outer wall portion of the head end of the material cavity tube, or the inner wall portion of the cover tube structure at the cover tube outlet is tightly fitted with the outer wall of the head end of the material cavity tube, so as to ensure the airtightness of the outlets of the two when they are misaligned, and to ensure that the material cannot leak into the gap or interlayer between the cover tube structure and the material cavity tube when the outlets of the two overlap; if necessary, a sealing plug or a sealing gasket is provided at the contact portion between the head end of the cover tube structure and the head end of the material cavity tube to strengthen the airtightness between the two after the cover tube structure is sleeved on the outer wall of the material cavity tube. The sealing plug or sealing gasket is usually made of rubber material, preferably silicone or butyl rubber; 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. The sealing plug or sealing gasket can also be made into a separate rubber accessory, and then the accessory is installed at the contact position between the head end of the cover tube structure and the head end of the material cavity. However, no matter which method is used, it is necessary not only to ensure the airtightness of the two outlets when they are misaligned, but also to ensure the smooth flow of the outlet of the cover tube structure and the outlet of the material cavity when the two outlets overlap.

[0022] It should be noted that regarding the concepts of the tail end and the head end of the material cavity tube, the cover tube structure or the control member, the head end refers to the end closest to the material in the container after they are installed on the container, and the other end is called the tail end.

[0023] When the material in the above-mentioned container closing device is in a storage state, the outlet of the cover tube structure and the outlet of the material cavity tube are misaligned with each other, and the cover tube structure is mounted on the material cavity tube by a snap and tightly closed together, so that the material in the material cavity tube or the chamber separated therein 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 or rotate the material cavity tube, or twist or rotate the control member to drive the material cavity tube to rotate, so that the outlet of the material cavity tube coincides with the outlet of the cover tube structure, and then press the control member to make the piston squeeze and discharge the material in the material cavity tube into the main chamber of the container, or pull the control member to make the piston away from the head end of the material cavity tube to generate negative pressure in the chamber, so that the liquid material in the main chamber of the container can be sucked into the material cavity tube or chamber, and pre-mixed or pre-dissolved with the material in the material cavity tube or chamber, and then press the control member to make the piston squeeze and discharge the pre-mixed material in the material cavity tube or chamber into the main chamber of the container, and mix it with the material in the container. Before opening the packaging container, only a simple operation of the material cavity and / or the control member is required to accurately and conveniently mix and prepare one or more materials in the material cavity or chamber with the material in the container, thereby achieving the purpose of mixing and preparing the materials before use; in addition, for special materials, such as materials that dissolve slowly or need to be dissolved step by step, they can be pre-mixed or pre-dissolved and then mixed and prepared with the materials in the main chamber of the container.

[0024] In addition, as described in the present invention, the material cavity and the cover cylinder structure rotate so that the outlet of the material cavity and the outlet of the cover cylinder structure overlap or misalign, which involves the structural connection between the material cavity and the cover cylinder structure and the operation of the control member, and also involves that when the piston member is pressed downward, the control member has a space channel that can be displaced and extended downward to ensure that the piston can slide to the head end of the material cavity and the material is completely discharged. The present invention preferably includes but is not limited to the following four schemes:

[0025] In the first embodiment of the present invention, the cover tube structure is sleeved on the outer wall of the material cavity tube and connected to each other, so that the head end of the cover tube structure is tightly fitted with the head end of the material cavity tube, and the tail end part of the material cavity tube protrudes from the top of the cover surrounding structure. The material cavity tube and the cover tube structure can be rotated by twisting the tail end of the material cavity tube, and the outlet of the material cavity tube and the outlet of the cover tube structure are further overlapped or misaligned. When their outlets are misaligned with each other, the outlet of the material cavity tube is sealed, and when their outlets overlap with each other, the outlet of the material cavity tube can be opened;

[0026] The material cavity tube and the cover tube structure are connected to each other, for example, including but not limited to connecting by snapping a convex buckle provided on the outer wall of the material cavity tube with a convex buckle provided on the inner wall of the cover tube structure, or connecting by snapping a convex buckle provided on the outer wall of the material cavity tube with a concave buckle groove provided on the inner wall of the cover tube structure, or connecting by snapping a concave buckle groove provided on the outer wall of the material cavity tube with a convex buckle provided on the inner wall of the cover tube structure;

[0027] The control member and the piston member are in the material cavity. When the piston member is pressed downward, the control member and the piston member slide in the material cavity toward the head end of the material cavity, ensuring that the control member and the piston member can move smoothly and that the piston can slide to the position of the head end of the material cavity.

[0028] In a second embodiment of the present invention, a fixed inner cylinder is disposed inside the cover cylinder structure, the fixed inner cylinder is connected and fixed to the head end of the cover cylinder structure, and an annular space structure is formed between the outer wall of the fixed inner cylinder and the inner wall of the cover cylinder structure;

[0029] The fixed inner cylinder arranged inside the cover cylinder structure is sleeved on the outer wall of the material cavity cylinder, and the cover cylinder structure and the material cavity cylinder can rotate with each other. The mutual rotation of the cover cylinder structure and the material cavity cylinder can realize that the outlet of the cover cylinder structure and the outlet of the material cavity cylinder overlap or misalign with each other. When their outlets are misaligned with each other, the outlet of the material cavity cylinder is sealed, and when their outlets overlap with each other, the outlet of the material cavity cylinder can be opened;

[0030] The material cavity tube and the fixed inner tube arranged inside the cover tube structure are connected to each other, for example, including but not limited to connecting by snapping a convex buckle arranged on the outer wall of the material cavity tube with a convex buckle arranged on the inner wall of the fixed inner tube, or connecting by snapping a convex buckle arranged on the outer wall of the material cavity tube with a concave buckle groove arranged on the inner wall of the fixed inner tube, or connecting by snapping a concave buckle groove arranged on the outer wall of the material cavity tube with a convex buckle arranged on the inner wall of the fixed inner tube;

[0031] The piston component is in the material cavity. When the piston component is pressed downward, the piston component slides toward the head end of the material cavity in the material cavity, and the control component extends into the annular space formed between the outer wall of the fixed inner cylinder and the inner wall of the cover cylinder structure, ensuring that the control component and the piston component can move smoothly and ensuring that the piston can slide to the position of the head end of the material cavity.

[0032] A third embodiment of the present invention, wherein a fixed inner cylinder is disposed inside the material cavity cylinder, the fixed inner cylinder is connected and fixed to the head end of the material cavity cylinder, and an annular space structure is formed between the outer wall of the fixed inner cylinder and the inner wall of the material cavity cylinder;

[0033] The cover tube structure is sleeved on the outer wall of the material cavity tube, and the cover tube structure and the material cavity tube can rotate with each other. The mutual rotation of the cover tube structure and the material cavity tube can achieve the overlap or misalignment of the outlet of the cover tube structure and the outlet of the material cavity tube.

[0034] The cover tube structure and the material cavity tube can rotate with each other. The mutual rotation of the cover tube structure and the material cavity tube can realize that the outlet of the cover tube structure and the outlet of the material cavity tube overlap or misalign with each other. When their outlets are misaligned with each other, the outlet of the material cavity tube is sealed. When their outlets overlap with each other, the outlet of the material cavity tube can be opened.

[0035] The material cavity tube and the cover tube structure are connected to each other, for example, including but not limited to connecting by snapping a convex buckle provided on the outer wall of the material cavity tube with a convex buckle provided on the inner wall of the cover tube structure, or connecting by snapping a convex buckle provided on the outer wall of the material cavity tube with a concave buckle groove provided on the inner wall of the cover tube structure, or connecting by snapping a concave buckle groove provided on the outer wall of the material cavity tube with a convex buckle provided on the inner wall of the cover tube structure;

[0036] The piston member is in the fixed inner cylinder of the material cavity cylinder. When the piston member is pressed downward, the piston member slides toward the head end of the fixed inner cylinder in the fixed inner cylinder, and the control member extends into the annular space formed between the outer wall of the fixed inner cylinder and the inner wall of the material cavity cylinder, ensuring that the control member and the piston member can move smoothly and ensuring that the piston can slide to the position of the head end of the material cavity cylinder.

[0037] A fourth embodiment of the present invention, wherein the diameter of the cylinder at the head end of the cover cylinder structure is smaller than the diameter of the cylinder at the tail end, the cover cylinder structure is sleeved on the outer wall of the material cavity, and an annular space structure is formed between the inner wall of the cylinder at the tail end of the cover cylinder structure and the outer wall of the material cavity;

[0038] The inner wall of the cylinder at the head end of the cover cylinder structure is connected to the outer wall of the material cavity, so that the head end of the cover cylinder structure is closely fitted with the head end of the material cavity, and the cover cylinder structure and the material cavity can rotate with each other. The mutual rotation of the cover cylinder structure and the material cavity can realize the overlap or misalignment of the outlet of the cover cylinder structure and the outlet of the material cavity. When their outlets are misaligned, the outlet of the material cavity is sealed, and when their outlets overlap, the outlet of the material cavity can be opened.

[0039] The inner wall of the barrel at the head end of the cover barrel structure and the outer wall of the material cavity barrel are connected to each other, for example, including but not limited to connecting by snapping a convex buckle provided on the outer wall of the material cavity barrel with a convex buckle provided on the inner wall of the barrel at the head end of the cover barrel structure, or connecting by snapping a convex buckle provided on the outer wall of the material cavity barrel with a concave buckle groove provided on the inner wall of the barrel at the head end of the cover barrel structure, or connecting by snapping a groove provided on the outer wall of the material cavity barrel with a convex buckle provided on the inner wall of the barrel at the head end of the cover barrel structure;

[0040] The piston component is in the material cavity. When the piston component is pressed downward, the piston component slides toward the head end of the material cavity in the material cavity, and the control component extends into the annular space formed between the inner wall of the cylinder at the tail end of the cover cylinder structure and the outer wall of the material cavity, ensuring that the control component and the piston component can move smoothly and ensuring that the piston can slide to the position of the head end of the material cavity.

[0041] The material contained in the material cavity or chamber of the present invention can be a liquid material, a solid material, a mixture of a solid and a liquid, or a slurry. The solid material is preferably a solid powder material, a solid granular material, or a tablet material. The solid granular material includes but is not limited to effervescent granules, rapidly disintegrating granules, and ordinary granules used in pharmacy, and the tablet material includes but is not limited to effervescent tablets, dispersible tablets, rapidly disintegrating tablets, and ordinary tablets used in pharmacy, and the like. Preferably, at least one of the materials is a liquid material, and the liquid material includes a water-soluble liquid material or a fat-soluble liquid material.

[0042] Preferably, the cover surrounding structure and the cover tube structure are interconnected and fixed. Preferably, the cover surrounding structure and the cover tube structure are an independent integral component, or the cover surrounding structure and the cover tube structure are independent components, and the cover tube structure and the cover surrounding structure are assembled and fixed together to form a cover component. The fixing method includes but is not limited to snap-on fixing, threaded fixing, welding fixing, adhesive bonding fixing, etc. It is most preferred that the cover surrounding structure and the cover tube structure are made into an independent plastic component by injection molding.

[0043] Furthermore, the internal space of the material cavity or the fixed inner cylinder of the material cavity can be divided into at least two chambers to achieve the independent sealing, storage and release of at least two materials or more materials, for example, it can accommodate two materials, three materials, four materials, five materials, six materials, etc. that are independent and sealed to each other, so as to meet the stability requirements or comprehensive deployment requirements of multiple materials. Preferably, a chamber baffle is set in the material cavity or the fixed inner cylinder of the material cavity, and the chamber baffle and the material cavity are an independent component fixed to each other, for example, a material cavity with a chamber baffle inside is made by injection molding to achieve the separation of the internal space of the material cavity into independent chambers, or the chamber baffle is assembled as a separate component inside the material cavity so that each chamber can be independent and easy to seal; the chamber baffle extends from the inner wall of the head end of the material cavity to the tail end of the material cavity, and the volume of the chamber can be freely divided inside the material cavity as needed.

[0044] It should be understood that when there is no separated chamber in the material cavity or the fixed inner cylinder of the material cavity, the spatial structure of the material cavity or the fixed inner cylinder of the material cavity can be regarded as having only one chamber and can only accommodate one type of material.

[0045] When the material cavity or the fixed inner cylinder of the material cavity is provided with separated chambers, each chamber has an outlet, and the outlet is located at the head end of the material cavity.

[0046] Preferably, the internal space of the material cavity or the internal space of the fixed inner cylinder of the material cavity is divided into two independent chambers to respectively accommodate two different materials, and the head end of the material cavity is provided with an outlet of each chamber, wherein each chamber of the material cavity is provided with at least one outlet as a release outlet for the material accommodated in the material chamber, and the head end of the cover cylinder structure is provided with at least one outlet of the cover cylinder structure; for example, the internal space of the material cavity or the internal space of the fixed inner cylinder of the material cavity is divided into an annular cylindrical chamber and a cylindrical chamber, or divided into two semicircular cylindrical chambers, or divided into two fan-shaped cylindrical chambers; and each chamber has a piston component matching the chamber.

[0047] Preferably, the internal space of the material cavity or the internal space of the fixed inner cylinder of the material cavity is divided into three independent chambers to respectively accommodate three different materials, and the front end of the material cavity is provided with an outlet of each chamber, wherein each chamber of the material cavity is provided with at least one outlet as a release outlet for the material accommodated in the material chamber, and the front end of the cover cylinder structure is provided with at least one outlet of the cover cylinder structure, and each chamber has a piston component matching the chamber.

[0048] When the material cylinder has two or more material chambers, each material chamber has a separate piston or piston component.

[0049] When the material cavity has two or more material chambers, preferably, each chamber of the material cavity may have the same control member, so that when the outlet of each material chamber coincides with the outlet of each cover tube structure at the same time, by pressing the independent control member, the materials in each chamber can be released and dispensed at the same time;

[0050] When the material cavity barrel has two or more material chambers, each material chamber may have its own independent control component as needed, so that when the outlets of different material chambers overlap with the outlets of the cover barrel structure, the materials in each chamber can be independently released and adjusted in sequence by pressing the independent control components, thereby achieving the effect of sequential and sequential release of different materials.

[0051] The number of outlets of each chamber of the material chamber is at least one, preferably each chamber has one outlet, 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.

[0052] When the material cavity has two or more material chambers, the number of outlets of the cover tube structure is the same as the number of outlets of all chambers and the corresponding outlets can overlap at the same time, the materials in each chamber can be released simultaneously by pressing the control component.

[0053] When the material cavity has two or more material chambers, the number of outlets of the cover tube structure can be different from the number of outlets of all chambers. Such a setting can achieve the following effects: the outlets of each chamber can overlap and misalign with the outlets of the cover tube structure at different rotation angles and different positions, so that the material cavity can control the order of material release in each chamber by pressing each independent control component within its rotation angle or range, so as to achieve the diversification of material release and make the preparation of each material 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 relative to each other, the outlets on each chamber of the material cavity can overlap with the outlets on the cover tube structure in turn, so that the materials in each chamber are released in turn;

[0054] For another example, when the material cavity barrel has two or more material chambers, when the number of outlets of the cover barrel structure is the same as the number of outlets of all chambers but the corresponding outlets cannot overlap at the same time, when the cover barrel structure and the material cavity barrel rotate relative to each other, the outlet on the material cavity barrel may overlap with the outlet on the cover barrel structure with a delay, so that the materials in the chambers are released sequentially or with a delay.

[0055] The size of the outlet of the cover tube structure and the outlet of the material cavity or chamber can be set according to the state of the released material. For liquid materials with good fluidity, the outlet of the cover tube and the outlet of the material cavity or chamber or their channels can be large or small. For materials with poor fluidity, such as high-viscosity liquid materials, slurries, solid powders, solid particles, solid flakes or blocks, the outlet of the cover tube and the outlet of the material cavity or chamber should be set larger to facilitate the smooth release of the material.

[0056] The outlet of the cover tube structure and the outlet of the material cavity or chamber can be of various shapes to facilitate the smooth release of the material. In particular, when the material contained therein is liquid, the outlet of the cover tube and the outlet of the material cavity or chamber are designed to be of various shapes so that the liquid material presents different shapes when released, including water column or liquid column, spray, etc.

[0057] Further, the container closure device of the present invention is provided with a stop mechanism or a locking mechanism between the cover member and other components, and the stop mechanism or the locking mechanism is engaged when the material cavity is rotated to a predetermined position relative to the cover structure to prevent or hinder the cover structure and the material cavity from further relative rotation, and the predetermined position includes and is preferably a position where the outlet of the cover structure and the outlet of the material cavity or chamber are mutually misaligned or overlapped, and the prevention or hindering of the 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 rotate further relative to each other, or there is an obstruction between the cover structure and the material cavity, and relative rotation can be achieved by increasing the force, but it cannot be easily rotated;

[0058] The stopping mechanism or locking mechanism includes a stopping mechanism or locking mechanism provided between the cover member and the material chamber, or a stopping mechanism or locking mechanism provided between the cover member and the control member, or a stopping mechanism or locking mechanism provided between the cover member and the piston member, and the stopping mechanism or locking mechanism is provided at any contactable position between the cover member and other components;

[0059] Preferably, the stop mechanism or locking mechanism is arranged at any contactable position between the cover tube structure and the material chamber tube;

[0060] Preferably, the stop mechanism or locking mechanism is arranged at any contactable position between the cover surrounding structure and the material cavity;

[0061] Preferably, the stop mechanism or locking mechanism is arranged at any contactable position between the cover tube structure and the control member;

[0062] Preferably, the stop mechanism or locking mechanism is arranged at any contactable position between the cover surrounding structure and the control member;

[0063] Preferably, the stop mechanism or locking mechanism is arranged at any contactable position between the cover cylinder structure and the piston member;

[0064] Preferably, the stopping mechanism or locking mechanism is arranged at any contactable position between the cover surrounding structure and the piston member.

[0065] For example, specifically, the stopping mechanism or locking mechanism can be arranged at any contactable position between the cover sleeve structure and the material cavity, for example, on the inner wall of the cover sleeve structure and the outer wall of the material cavity, or on the inner wall of the cover sleeve structure and the wall of the material cavity, or on the inner wall of the fixed inner sleeve of the cover sleeve structure and the outer wall of the material cavity, or on the inner wall of the fixed inner sleeve of the cover sleeve structure and the wall of the material cavity.

[0066] For the stopping mechanism or locking mechanism, preferably, on the inner wall of the cover barrel structure and the outer wall of the material cavity barrel, or on the inner wall of the fixed inner barrel of the cover barrel structure and the outer wall of the material cavity barrel, in the direction parallel to the central axis of the cover barrel structure or the material cavity barrel, at least one mutually matching rib or buckle is arranged, as a rotation positioning rib or rotation positioning buckle of the cover barrel structure and the material cavity barrel, for positioning the cover barrel outlet and the material cavity barrel or the chamber outlet at a specific position when they are misaligned or overlapped during the mutual rotation process, the rib or buckle includes a convex or groove-shaped arrangement arranged on the inner wall of the barrel of the cover barrel structure and the outer wall of the material cavity barrel, or the rib or buckle includes the inner wall of the barrel of the cover barrel structure and the wall of the material cavity barrel. The convex or concave arrangement is arranged on the cover, and the arrangement includes a strip, a column, a sheet or a concave arrangement. The ribs or buckles arranged on the inner wall of the barrel of the cover barrel structure and the outer wall of the material cavity barrel match each other, and the purpose is that when the cover barrel structure and the material cavity barrel are rotated to a specific position, especially when they are rotated to a position where their outlets overlap or are misaligned, the rotation positioning ribs or rotation positioning buckles prevent the cover barrel structure and the material cavity barrel from rotating relative to each other or being easily rotated, so as to provide accurate positioning and control of the release time for the full release of the material, and to ensure the safe storage of the material in a sealed state; the barrel of the cover barrel structure includes the barrel of the cover barrel structure itself, or the barrel of the fixed inner barrel of the cover barrel structure;

[0067] Preferably, the ribs or buckles are evenly or symmetrically distributed on the outer wall circumference of the material cavity, or preferably, the ribs or buckles are evenly or symmetrically distributed on the inner wall circumference of the cylinder of the cover cylinder structure; this arrangement avoids centrifugal rotation or eccentric rotation of the material cavity and the cover cylinder structure, thereby avoiding the error and uncontrollability when the cover cylinder outlet overlaps with the material chamber outlet due to centrifugal rotation, which plays a vital role in accurately controlling the release of the material in the chamber;

[0068] Preferably, when the cover barrel structure and the material cavity barrel rotate to the rib or buckle position, the cover barrel outlet and the material cavity barrel or chamber outlet are staggered at a preset position to facilitate the sealing and preservation of the material, or the cover barrel outlet and the material cavity barrel or chamber outlet are overlapped to facilitate the release of the material, or when the cover barrel structure and the material cavity barrel rotate to the rib or buckle position, the cover barrel structure and the material cavity barrel can no longer rotate relative to each other or cannot be easily rotated, and the cover barrel outlet and the material cavity barrel or chamber outlet are staggered to ensure that the product will not be accidentally released during storage, transportation, etc.; in addition, when it cannot be easily rotated, when sliding past the rib or buckle, a slight vibration or a subtle sound will be generated, and the user will feel this vibration or sound when rotating or twisting, which is convenient for the user to control the hand feel during operation;

[0069] For example, a rib is provided on the outer wall of the material cavity, and when the cover tube outlet is misaligned with the outlet of the material cavity or chamber, the rib is located in the middle position of two ribs provided on the inner wall of the cover tube structure, so that the cover tube structure and the material cavity cannot be easily rotated, so as to prevent the accidental release of the product in storage, transportation, etc.; or, for example, a rib is provided on the outer wall of the material cavity, and when the cover tube outlet is coincident with the outlet of the material cavity or chamber, the rib is located in the position of a rib provided on the inner wall of the cover tube structure, and the two groups of ribs engage with each other and hinder rotation, so that the cover tube structure and the material cavity can no longer rotate relative to each other or cannot be easily rotated, so as to prevent the disadvantage of the failure of smooth release of the material due to the position deviation of the coincidence of the outlets, which is conducive to the smooth and complete release of the material;

[0070] In addition, the setting of the above-mentioned ribs or baffles can accurately control the rotation distance or range of the cover barrel outlet and the material cavity or chamber outlet when they are misaligned or overlapped with each other. On the other hand, when the cover barrel structure and the material cavity rotate relative to each other, this device can avoid multiple, unnecessary misalignments or overlaps between the cover barrel outlet and the material cavity or chamber outlet. The ribs or baffles determine the movement range of the cover barrel outlet and the material cavity or chamber outlet when they are misaligned or overlapped with each other.

[0071] On the other hand, the stop mechanism or locking mechanism can be arranged at any contactable position between the cover tube structure and the control member, for example, on the inner wall of the cover tube structure and the control member, or on the outer wall of the fixed inner tube of the cover tube structure and the control member, or on the outer wall of the cover surrounding structure and the control member;

[0072] For example, preferably, at least one mutually matching rib or buckle is provided on the inner wall and the control member of the cover barrel structure, or on the outer wall and the control member of the fixed inner barrel of the cover barrel structure, or on the outer wall and the control member of the cover surrounding structure, in a direction parallel to the central axis of the cover barrel structure or the material chamber barrel, as a rotation positioning rib or rotation positioning buckle of the cover barrel structure and the material chamber barrel, for positioning the cover barrel outlet and the material chamber barrel or the chamber outlet at a specific position when they are misaligned or overlapped during the mutual rotation process, and the rib or buckle is provided on the position of the above-mentioned cover member and on the control member. The convex or concave arrangement includes a strip, column, sheet or concave arrangement, and the ribs or buckles arranged on the cover member and the control member match each other, and the purpose is that when the cover cylinder structure and the material cavity cylinder are rotated to a specific position, especially when they are rotated to a position where their outlets overlap or are misaligned, the rotation positioning ribs or rotation positioning buckles prevent the cover cylinder structure and the material cavity cylinder from rotating relative to each other or from being easily rotated, so as to provide accurate positioning and control of the release time for the full release of the material, and to ensure the safe storage of the material in a sealed state;

[0073] Preferably, the ribs or buckles are evenly or symmetrically distributed on the inner wall circumference of the cover cylinder structure, or preferably, the ribs or buckles are evenly or symmetrically distributed on the outer wall circumference of the outer wall of the fixed inner cylinder of the cover cylinder structure, or preferably, the ribs or buckles are evenly or symmetrically distributed on the outer wall of the cover surrounding structure; this arrangement avoids centrifugal rotation or eccentric rotation of the material cavity cylinder and the cover cylinder structure, thereby avoiding the error and uncontrollability of the overlap between the cover cylinder outlet and the material chamber outlet caused by centrifugal rotation, which plays a vital role in accurately controlling the release of the material in the chamber;

[0074] Preferably, when the cover barrel structure and the material cavity barrel rotate to the rib or buckle position, the cover barrel outlet and the material cavity barrel or chamber outlet are staggered at a preset position to facilitate the sealing and preservation of the material, or the cover barrel outlet and the material cavity barrel or chamber outlet are overlapped to facilitate the release of the material, or when the cover barrel structure and the material cavity barrel rotate to the rib or buckle position, the cover barrel structure and the material cavity barrel can no longer rotate relative to each other or cannot be easily rotated, and the cover barrel outlet and the material cavity barrel or chamber outlet are staggered to ensure that the product will not be accidentally released during storage, transportation, etc.; in addition, when it cannot be easily rotated, when sliding past the rib or buckle, a slight vibration or a subtle sound will be generated, and the user will feel this vibration or sound when rotating or twisting, which is convenient for the user to control the hand feel during operation;

[0075] For example, a rib is provided on the inner wall of the cover barrel structure. When the cover barrel outlet is misaligned with the outlet of the material cavity or chamber, the rib is located in the middle position of the two ribs provided on the control member, so that the cover barrel structure and the material cavity cannot be easily rotated, so as to prevent the accidental release of the product in storage, transportation, etc.; or, for example, a rib is provided on the inner wall of the cover barrel structure. When the cover barrel outlet is coincident with the outlet of the material cavity or chamber, the rib is located in the position of a rib provided on the control member, and the two ribs engage with each other and hinder the rotation, so that the cover barrel structure and the material cavity can no longer rotate relative to each other or cannot be easily rotated, so as to prevent the disadvantage of the failure of smooth release of the material due to positional deviation of the coincidence of the outlets, which is conducive to the smooth and complete release of the material.

[0076] Further, on the other hand, the stop mechanism or locking mechanism can be arranged at any contactable position between the cover cylinder structure and the piston support member, for example, arranged on the inner wall of the cover cylinder structure and the piston support member, or arranged on the inner wall of the fixed inner cylinder of the cover cylinder structure and the piston support member;

[0077] For example, preferably, on the inner wall of the cover barrel structure and the piston support, or on the inner wall of the fixed inner barrel of the cover barrel structure and the piston support, in the direction parallel to the central axis of the cover barrel structure or the material chamber, at least one mutually matching rib or stopper is arranged, which serves as a rotation positioning rib or rotation positioning stopper for the cover barrel structure and the material chamber, and is used to position the cover barrel outlet and the material chamber outlet at a specific position when they are misaligned or overlapped during the mutual rotation process. The rib or stopper includes a convex or concave setting arranged on the inner wall of the barrel of the cover barrel structure and the piston support, and the setting includes strips, columns, sheets, etc. The inner wall of the cylinder body of the cover cylinder structure and the ribs or buckles on the piston support match each other, and the purpose is that when the cover cylinder structure and the material cavity cylinder are rotated to a specific position, especially when they are rotated to a position where their outlets overlap or are misaligned, the rotation positioning ribs or rotation positioning buckles prevent the cover cylinder structure and the material cavity cylinder from rotating relative to each other or being easily rotated, thereby providing accurate positioning and release time control for the full release of the material, and ensuring the safe storage of the material in a sealed state; the cylinder body of the cover cylinder structure includes the cylinder body of the cover cylinder structure itself, or the cylinder body of the fixed inner cylinder of the cover cylinder structure;

[0078] Preferably, when the cover barrel structure and the material cavity barrel rotate to the rib or buckle position, the cover barrel outlet and the material cavity barrel or chamber outlet are staggered at a preset position to facilitate the sealing and preservation of the material, or the cover barrel outlet and the material cavity barrel or chamber outlet are overlapped to facilitate the release of the material, or when the cover barrel structure and the material cavity barrel rotate to the rib or buckle position, the cover barrel structure and the material cavity barrel can no longer rotate relative to each other or cannot be easily rotated, and the cover barrel outlet and the material cavity barrel or chamber outlet are staggered to ensure that the product will not be accidentally released during storage, transportation, etc.; in addition, when it cannot be easily rotated, when sliding past the rib or buckle, a slight vibration or a subtle sound will be generated, and the user will feel this vibration or sound when rotating or twisting, which is convenient for the user to control the hand feel during operation;

[0079] For example, a rib is provided on the piston support, and when the cover barrel outlet is misaligned with the outlet of the material cavity barrel or chamber, the rib is in the middle position of two ribs provided on the inner wall of the barrel body of the cover barrel structure, so that the cover barrel structure and the material cavity barrel cannot be easily rotated, so as to prevent the accidental release of the product in storage, transportation, etc., or for example, a rib is provided on the piston support, and when the cover barrel outlet is coincident with the outlet of the material cavity barrel or chamber, the rib is in the position of a rib provided on the inner wall of the barrel body of the cover barrel structure, and the two ribs are engaged with each other and hinder the rotation, so that the cover barrel structure and the material cavity barrel can no longer rotate with each other or cannot be easily rotated, so as to prevent the disadvantage of the material not being released smoothly due to the position deviation of the coincidence of the outlets, which is conducive to the smooth and complete release of the material. The barrel body of the cover barrel structure includes the barrel body of the cover barrel structure itself, or the barrel body of the fixed inner barrel of the cover barrel structure.

[0080] If necessary, the control member may be provided with a screwing mechanism to facilitate screwing or rotating the control member. Preferably, the screwing mechanism is provided in a shape that is convenient for the user to rotate or screw by hand, for example, the screwing mechanism is provided in a shape that is convenient for the user to grasp or press the rear end of the cover member, so as to activate the stop mechanism or locking mechanism by screwing or pressing. Preferably, the screwing mechanism is provided on the outer surface of the control member and has a convex-concave structure, such as a sheet, strip, or cylinder, or is provided on the outer surface of the control member to have a non-smooth outer surface, such as a frosted outer surface, engraved texture, concave-convex lines or concave-convex texture, etc.;

[0081] If necessary, the control member may be provided with a pressing surface interface to facilitate sliding the piston toward the head end of the material chamber by pressing the control member. The pressing surface interface is usually provided as a plane or arc surface at the top of the control member to facilitate the user to perform a pressing operation by hand.

[0082] If necessary, a pulling and pulling mechanism may be provided on the control member to facilitate sliding the piston toward the tail end of the material cavity by pulling or pulling the control member, thereby causing the piston to generate negative pressure in the material cavity or chamber, and sucking the liquid material in the main chamber of the container into the material cavity or chamber, and pre-mixing or pre-dissolving it with the material in the material cavity or chamber; preferably, the pulling and pulling mechanism is arranged at the tail end of the control member, for example, the tail end of the control member is arranged to be a concave or convex mechanism, or a pull ring structure or a pull sheet structure is arranged at the tail end of the control member, so as to facilitate the user to pull or pull it by hand.

[0083] If necessary, a screwing mechanism may be provided on the tail end of the material cavity to facilitate twisting or rotating the tail end of the material cavity. Preferably, the screwing mechanism is provided in a shape that is convenient for the user to rotate or twist by hand, for example, the screwing mechanism is provided in a shape that protrudes from the tail end of the material cavity to facilitate the user to grasp by hand, so as to activate the stop mechanism or locking mechanism by screwing operation. Preferably, the screwing mechanism is provided on the outer surface of the material cavity and has a convex-concave structure, such as a sheet, strip, or column, or a non-smooth outer surface is provided on the outer surface of the tail end of the material cavity, such as a frosted outer surface, engraved texture, concave-convex lines or concave-convex texture, etc.

[0084] If necessary, the portion where the tail end of the material chamber is close to or in contact with the cover member may be provided with a structure having an anti-theft opening, or the portion where the control member is close to or in contact with the cover member may be provided with a structure having an anti-theft opening, such as providing a circle of point-shaped connecting circles or point-shaped connecting points having anti-theft opening, or providing a section or a circle of tear strips that are easy to tear open and remove, etc. The anti-theft opening structure has the function of providing anti-theft protection for the container closure device described in the present invention when it is in the commodity circulation link and preventing the container closure device from being accidentally opened.

[0085] Furthermore, if necessary, a cover can be provided on the outside of the cover member, and the cover is used to protect the tail end of the material cavity tube or the control member to prevent the tail end of the material cavity tube or the control member from being accidentally rotated or pressed. The cover also provides the container closure device of the present invention with overall aesthetics. The cover can be provided above the tail end of the material cavity tube and cover the tail end of the material cavity tube or the control member, and the cover is preferably connected to the cover member;

[0086] Alternatively, the cover is a film material that adheres to the opening at the rear end of the cover tube structure. Preferably, the film material adheres to the cross-section of the wall at the rear end of the cover tube structure to wrap the control member in the cover tube structure. When in use, the film material needs to be torn off or broken to expose the control member, and the control member is twisted or pressed to release the contents in the material cavity. Most preferably, the height of the opening at the rear end of the cover tube structure is not lower than the height of the control member to facilitate the film material to adhere to the cross-section of the wall at the rear end of the cover tube structure, so as to achieve better wrapping effect and neat appearance. Preferably, the film material is polymer plastic, aluminum-plastic composite material, paper-plastic composite material, paper, aluminum foil, for example, a film material of polymer plastic, aluminum-plastic composite or paper-plastic composite is adhered to the cross-section of the wall at the rear end of the cover tube structure.

[0087] Preferably, the tail end component of the material cavity tube of the container closure device of the present invention protrudes from the top of the cover structure, and the overall structural shape is raised. Its advantages and importance are: it is convenient for the cover tube structure to be connected and stabilized with the material cavity tube; it is also beneficial to expand the volume of the material cavity tube outward, to accommodate more materials, and to separate more chambers in the material cavity tube to accommodate more different types of materials, and it is also beneficial to meet the mutual connection and sealing assembly operations between the cover component and the material cavity tube.

[0088] Furthermore, as needed, a circle of easy-to-tear connection ring or point-shaped connection contacts with anti-theft opening can be set at the bottom of the outer periphery of the cover surrounding structure. The easy-to-tear connection 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 closure device is installed on the container neck and the container needs to be opened and the cover surrounding structure needs to be twisted or rotated, the easy-to-tear connection ring is broken due to the blocking effect of the point-shaped connection contacts or micro-connections provided on the outer wall of the container neck, and the easy-to-tear connection ring is separated from the cover surrounding structure, thereby playing a role in anti-theft opening.

[0089] If necessary, a layer of gasket can be provided on the inner surface 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 gasket is a rubber gasket, and the most preferred gasket is a silicone gasket.

[0092] As described above, the container closing device is installed on the neck of the container to form a packaging container. Before opening the packaging container or using the mixed material, only the material in the material cavity or chamber can be released to the main chamber of the container under the squeezing action of the piston by twisting and pressing the control member, or only the material cavity and the control member can be twisted and pressed. The material is mixed with the material in the main chamber of the container, thereby achieving the purpose of mixing and formulating the material before use; in addition, the packaging container of the present invention has the function of premixing or predissolving the material in the container closing device. For example, by pulling the control member to make the piston away from the head end of the material cavity, a negative pressure is generated in the material cavity, and the liquid material in the main chamber of the container is sucked into the material cavity, and premixed or predissolved with the material in the material cavity, and then the piston is pressed by pressing the control member to squeeze the premixed material in the material cavity into the main chamber of the container, and mixed with the material in the main chamber of the container, thereby achieving the purpose of premixing or predissolving special materials first and then mixing and formulating with the material in the main chamber of the container.
