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. The sealing device is used to open an outlet of the sealing device under the action of piston pressure to release materials contained separately and independently into materials in the container through operation of the sealing device, and to mix various materials together through operation outside the lid of the container before opening the packaging container, so as to achieve automatic mixing.

[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, it is necessary to store two or more different substances or materials in the product separately during the shelf life of the product to make it more conducive to the stability, freshness, function assurance or other quality improvements of the product. The existing technical solution uses two or more different packaging bottles / bags / boxes for independent packaging, and recombines them together when using them, which is easy to cause many unfavorable factors 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. 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 performance, 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; 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.

[0006] The container of the present invention includes a 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, a packaging barrel or a packaging cup, and the like.

[0007] 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, so that the materials in the closing device puncture or break the outlet of the closing device under the action of piston pressure, or break through the sealing plug, so that the materials in the closing device are released into the independently sealed materials in the container, so as to achieve the technical solution of sealing and storing or releasing the materials in the closing device before opening the packaging container, and after the materials in the closing device are mixed and formulated with the materials in the main chamber of the container, the mixed materials in the packaging container can still be in a sealed state.

[0008] The present invention adopts the following technical solutions.

[0009] A container closing device, comprising a cover member, a piston member, an outlet sealing device, an outlet opening device, 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;

[0010] The rear end of the cover cylinder structure is connected to the cover surrounding structure, the rear end of the cover cylinder structure is open, and the front end of the cover cylinder structure is provided with an outlet of the cover cylinder structure.

[0011] The piston member comprises a piston and a piston support member, wherein the piston is connected to the piston support member, and the piston is in a cover cylinder structure; preferably, the piston is made of a polymer material, preferably made of rubber, plastic or other materials, and most preferably made of a rubber material, for example, preferably made of a silicone material or butyl rubber;

[0012] The piston can be made of a single polymer material or rubber material, and the piston is installed at one end of the piston support member; or the piston support member can be formed by encapsulating the rubber material at one end of the piston support member by injection molding, and the piston support member is preferably a connecting rod, cylinder or columnar structure;

[0013] Alternatively, the piston and the piston support member may also be made of the same plastic material, for example, the piston may be made into a plastic member that fits tightly against the inner wall of the cylinder in which it is located, and connected to or assembled on the piston support member to form a piston component.

[0014] The outlet sealing device is located at the outlet of the cover tube structure and seals the outlet of the cover tube structure, including sealing the outlet of the cover tube structure by using a thin sheet sealing material or a sealing plug. Preferably, the thin sheet sealing material is a material that is easy to be punctured or broken and has good sealing performance, such as a thin polymer material, including plastic, plastic, aluminum-plastic composite material, etc. Preferably, the cover tube structure and the sealing material at the outlet are made of the same polymer material as a whole, and the thickness of the sealing material is less than the thickness of the barrel material of the cover tube structure, or the sealing material is pressed with convex and concave patterns; or the cover tube structure and the sealing material are made of different materials, for example, the sealing material is sealed with a polymer film material or a thin sheet material to facilitate puncturing or breaking the sealing material, or the part where the sealing material is connected to the outlet of the cover tube structure is set as a groove-type connection, so that it has both sealing performance and easy to be broken; the sealing plug is made of a polymer material, preferably a rubber polymer material.

[0015] The outlet opening device is connected to the piston support or the control member and is located at the outlet of the cover tube structure. It has the function of generating displacement under the action of the piston support or the control member to open the outlet sealing device. Preferably, the outlet opening device includes a piercing member with a puncturing or popping function and a sealing plug valve member with a function of opening the sealing plug. Preferably, the piercing member is connected to the piston support or the control member and is located at a position directly opposite to the outlet of the cover tube structure. The piercing member is provided with a piercing head and a piercing head channel. The piercing head can pierce or pop the outlet of the cover tube structure, and under the action of the piston member, the material in the cover tube structure is released through the piercing head channel; the sealing plug valve member is connected to the piston support or the control member and interacts with the sealing plug, so that the sealing plug has the function of sealing or opening the outlet of the cover tube structure.

[0016] The control member is connected to the piston support member, and the control member can act on the piston support member to enable the piston to slide in the cylinder body of the cover cylinder structure and seal the cylinder body;

[0017] The control member and the cover member can rotate with each other, and the control member has a locking mechanism interconnected with the cover member, the locking mechanism has the function of relatively fixing and protecting the control member, and when the locking mechanism is in the locked position, it can prevent the control member from being accidentally pressed or pulled and thus displaced;

[0018] Preferably, the control member is a cylindrical structure. More preferably, a locking mechanism with a latch structure that matches each other is provided on the outer wall of the control member and the inner wall of the cover cylinder structure, or a locking mechanism that matches each other is provided on the inner wall of the control member and the outer wall of the cover structure, or a locking mechanism that matches each other is provided on the piston support and the inner wall of the cover cylinder structure; the locking mechanism includes a structural setting in the shape of a protrusion, a groove or a track, which includes but is not limited to a strip, a column, a sheet or a groove.

[0019] The inner cavity of the cover barrel structure is used to accommodate materials, and when the materials are sealed in the inner cavity of the cover barrel structure, there is space in the inner cavity of the cover barrel structure that is not occupied by the materials, and there is gas in the space or it is in a vacuum. Preferably, there is gas in the space, and the gas preferably includes nitrogen and air. For example, the air pressure of the space is preferably the same as or lower than the atmospheric pressure, or the air pressure of the space is slightly higher than the atmospheric pressure. Its function is that when the locking mechanism or the latch structure is opened and the control member is pressed, the piston is displaced, the gas in the space is compressed, and the outlet opening device is driven to displace and approach the outlet of the cover barrel structure, further opening the outlet sealing device, and at the same time, the control member pushes the piston to the head end of the cover barrel structure. Under the combined action of the high pressure generated by the compressed gas and the piston pressure, the materials are quickly, smoothly and completely released. For example, pressing the control member drives the piercing member to displace and approach the outlet of the cover barrel structure, further piercing or breaking the sealing material of the outlet of the cover barrel structure. Under the combined action of the high pressure generated by the compressed gas and the piston pressure, the materials are quickly and smoothly released or ejected.

[0020] It should be noted that regarding the concepts of the tail end and the head end of the cover cylinder structure, the control member, the piston support or the piston 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.

[0021] When the material in the above-mentioned container closure device is in a storage state, the material is in the cover tube structure, the piston and the sealing material at the outlet of the cover tube structure seal the inner cavity of the cover tube structure, and a space is reserved in the cover tube structure, and there is gas in the space, and there is a certain distance between the piercing head and the sealing material at the outlet of the cover tube structure, or there is a certain distance between the sealing plug and the outlet head end of the cover tube structure, so that the material in the cover tube structure is in an independently sealed state; the container closure 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 control member to open the locking mechanism or the latch structure, and then press the control member to displace the piston, compress the gas in the space, and drive the piercing member or the sealing plug valve member to displace and approach the outlet of the cover tube structure, further puncture or break the sealing material at the outlet of the cover tube structure, or open the sealing plug. Under the combined action of the high pressure generated by the compressed gas and the piston pressure, the control member also pushes the piston to the head end of the cover tube structure, so that the material is quickly, smoothly and completely released or sprayed out, and mixed with the material in the container. Before opening the packaging container, only a simple operation of the control member is required to accurately, quickly and conveniently mix the material in the cover tube structure with the material in the container, thereby achieving the purpose of mixing and preparing the materials before use.

[0022] The material contained in the cover tube structure 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.

[0023] Furthermore, the internal space of the cover tube structure 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 blending requirements of multiple materials. Preferably, a chamber baffle is provided in the cover tube structure, and preferably the chamber baffle and the cover tube structure are an independent component fixed to each other, for example, a cover tube structure with a chamber baffle inside is made by injection molding to achieve the separation of the internal space of the cover tube structure into independent chambers, or the chamber baffle is assembled as a separate component inside the cover tube structure 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 cover tube structure to the tail end of the cover tube structure, and the volume of the chamber can be freely divided inside the cover tube structure as needed.

[0024] It should be understood that when there is no separated chamber in the cover tube structure, the spatial structure of the cover tube structure itself can be regarded as having only one chamber that can only accommodate one type of material.

[0025] When the cover cylinder structure is provided with separated chambers, each chamber has an outlet, and the outlet is located at the head end of the cover cylinder structure.

[0026] Preferably, the internal space of the cover barrel structure is divided into two independent chambers to respectively accommodate two different materials, and the head end of the cover barrel structure is provided with an outlet of each chamber, wherein each chamber of the cover barrel structure is provided with at least one outlet as a release outlet for the material accommodated in the chamber; for example, the internal space of the cover barrel structure is divided into an annular cylindrical chamber and a cylindrical chamber, or into two semicircular cylindrical chambers, or into two fan-shaped cylindrical chambers; and each chamber has a piston component matching the chamber.

[0027] Preferably, the internal space of the cover cylinder structure is divided into three independent chambers to respectively accommodate three different materials. The head end of the cover cylinder structure is provided with an outlet for each chamber, wherein each chamber is provided with at least one outlet as a release outlet for the material contained in the chamber, and each chamber has a piston component matching the chamber.

[0028] When the cover cylinder structure has two or more material chambers, each chamber has a separate piston or piston component.

[0029] When the cover cylinder structure has two or more chambers, preferably, each chamber of the cover cylinder structure may have the same control member, so that when the outlets of each chamber are opened, by simultaneously pressing the respective independent piston members, the materials in each chamber can be released and dispensed at the same time;

[0030] When the cover cylinder structure has two or more material chambers, each chamber may have its own independent control component as needed, so that when the outlets of different chambers are opened, the materials in each chamber can be released and adjusted independently in sequence by pressing the independent control components in sequence, thereby achieving the effect of sequential and sequential release of different materials.

[0031] The size of the outlet of the cover cylinder structure can be set according to the state of the released material. For liquid materials with good fluidity, the outlet of the cover cylinder structure or its channel 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 cylinder structure can be set larger to facilitate the smooth release of the material.

[0032] The outlet of the cover cylinder structure can be of various shapes to facilitate the smooth release of materials. In particular, when the material contained therein is liquid, the outlet of the cover cylinder structure is designed to be of various shapes so that the liquid material presents different shapes when released, including water column or liquid column, spray, etc.

[0033] If necessary, a pressing surface interface may be provided on the control member to facilitate sliding the piston toward the head end of the cover cylinder structure by pressing the control member. The pressing surface interface is usually set to be a plane or arc surface at the top of the control member to facilitate the user to perform a pressing operation by hand.

[0034] If necessary, 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 function, such as a circle of dot-shaped connecting circles or dot-shaped connecting points having an anti-theft opening function, or 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.

[0035] Furthermore, if necessary, a cover can be provided on the outside of the cover member, and the cover is used to protect the rear end of the cover tube structure or the control member to prevent the control member from being accidentally pressed. The cover also provides the container closure device of the present invention with overall aesthetics. The cover can be connected to the cover member;

[0036] 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 cover tube structure. 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.

[0037] Preferably, the control member of the container closure device of the present invention protrudes from the top of the cover surrounding structure, and the overall structural shape is a raised one. Its advantages and importance lie in: facilitating the cover tube structure to expand the volume of accommodating materials outward, facilitating more accommodating materials, and facilitating pressing the control member and increasing the displacement range of the piston.

[0038] 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.

[0039] Furthermore, as needed, the part of the control member that contacts the cover member can be provided with a device for preventing theft and opening. For example, a circle of easy-to-tear connection rings or point-shaped connection contacts for preventing theft and opening is preferably provided at the bottom of the periphery of the control member. The easy-to-tear connection ring is connected to the control member by contact connection or micro-connection. When the control member is installed on the cover member and connected to a stopper provided on the cover surrounding structure or the cover tube structure, when the control member needs to be twisted or rotated, the easy-to-tear connection ring is broken due to the stopper of the cover surrounding structure or the cover tube structure, and the easy-to-tear connection ring is separated from the cover surrounding structure, thereby preventing theft and opening.

[0040] 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. For example, a layer of rubber gasket is applied on the inner surface of the top of the cover surrounding structure by a glue dripping method.

[0041] Another aspect of the present invention provides a packaging container, comprising the container closure device and a container according to the present invention, wherein the container comprises a container neck with an opening and a main body chamber, and the container closure device is installed on the neck of the container, wherein the container closure device is connected to the neck of the container through a thread or buckle provided on the inner wall of the side enclosure of its cover enclosure structure, or the container closure device is sealed with the neck of the container through the outer wall of the side enclosure of its cover enclosure structure by bonding or welding; the main body chamber of the container accommodates a first material, and the chamber of the cover tube structure in the container closure device accommodates a second material or more materials; the container, for example, comprises a packaging bottle, packaging bag, packaging can, packaging cup, packaging box or packaging barrel, etc., having an open container neck;
