Description

Technical Field The present invention relates to the field of product packaging containers, in particular to a packaging container used for separately accommodating different independently sealed materials. When the packaging container is opened or the bottle cap is twisted, various materials can be automatically mixed together to achieve automatic preparation.

[0001] The packaging container includes a packaging bottle, a packaging bag with a sealing cover, a packaging bag with a sealing plug, and the like.

[0002] 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 and its application. Background Art For products such as beverages, drinking wine, health foods, special medical purpose 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 products separately during the shelf life of the products, so as to make it more conducive to the stability, freshness, function assurance or other quality improvements of the products. The existing technical solutions use two or more different packaging bottles / bags / boxes for independent packaging, and then recombine them for use when in use, which easily causes 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 deficiencies of the above-mentioned prior art, the present invention provides a new type of packaging container with simple structure, accurate control, easy to carry, store and transport, and a material-separated packaging container with automatic mixing and blending functions. The packaging container not only has the overall commodity sealing performance, but also can independently seal two or more materials separately configured in the container. When the user or consumer opens the packaging container or twists the container cover, the independently sealed contents in the container can be automatically mixed and blended together, which not only ensures the stability, freshness, functional quality or other quality of the product, but also allows the user or consumer to intuitively feel the special properties of the product contents, and also allows the user or consumer to get a sense of pleasure from the process of automatic product blending. The present invention also relates to a packaging composition, an assembly method and an application of the packaging container.

[0006] The packaging container of the present invention includes a packaging container with an open container neck, preferably including a packaging bottle, a packaging bag, a packaging can, and the packaging bag especially includes a packaging bag with a sealing cover or a packaging bag with a sealing plug, etc. In order to clearly explain the present invention, the following description focuses on the structure of the packaging bottle to illustrate the technical solution of the present invention, but the technical solution of the present invention is also applicable to packaging bags and packaging cans, especially packaging bags with sealing covers and packaging bags with sealing plugs.

[0013] When the material in the packaging container is in a storage state, the outlet of the inner cylinder of the bottle cap and the outlet of the inner cylinder cap are misaligned with each other, and the inner cylinder cap is mounted on the inner cylinder of the bottle cap by snapping or threading and tightly closed together, so that the second material or more materials are in an independently sealed state; when the packaging container is opened or the bottle cap is twisted, the bottle cap drives the inner cylinder of the bottle cap to rotate together under the action of the reverse rotation blocking device, and the inner cylinder cap cannot rotate due to the obstruction of the rotation blocking device, so that the inner cylinder of the bottle cap and the inner cylinder cap rotate with each other, so that the outlet of the inner cylinder of the bottle cap and the outlet of the inner cylinder cap coincide with each other, and the second material or more materials in the inner cylinder of the bottle cap will be automatically released or ejected under the action of gravity or the extrusion of the elastic body, and mixed with the first material, so that the purpose of automatically and quickly mixing and blending the second material or more materials with the first material can be achieved in the process of opening the packaging container or only by twisting the bottle cap.

[0014] It should be noted that, regarding the concepts of the tail end and the head end of the bottle cap inner tube or the inner tube cap, the tail end of the bottle cap inner tube or the inner tube cap refers to the end connected to or close to the bottle cap, and the head end of the bottle cap inner tube or the inner tube cap refers to the other end, or the end with the chamber opening. The second material or more materials refers to the second material or more materials than the second material, such as the second material, the third material, the fourth material, the fifth material, and so on.

[0015] Among them, the reverse rotation hindering device refers to a concave or convex setting set at the tail end of the inner tube of the bottle cap, and a device that matches the sheet-shaped, inclined sheet-shaped or inverted setting on the inner wall of the bottle cap. Alternatively, the reverse rotation hindering device is a sheet-shaped, inclined sheet-shaped or inverted setting set at the tail end of the inner tube of the bottle cap, and a device that matches the concave or convex setting on the inner wall of the bottle cap. The device can allow the bottle cap to pass when it rotates in one direction, but be blocked when it rotates in the opposite direction. Such settings match each other and are usually made of plastic, rubber or plastic materials. According to the elastic deformation of the material itself and the designed structure, the inner tube of the bottle cap can rotate in one direction, but be blocked when it rotates in the opposite direction. Preferably, the bottle cap can be allowed to rotate in the clockwise direction, while being blocked when rotating in the counterclockwise direction; the concave or convex arrangement includes a serrated, sheet-shaped, oblique sheet-shaped or inverted arrangement, or an arrangement with a concave or convex functional structure formed by a serrated, sheet-shaped, oblique sheet-shaped or inverted member;

After the material is filled into the bottle cap inner cylinder and the elastomer is placed, the tail end of the bottle cap inner cylinder is sealed by the sealing cap. Preferably, the sealing cap has a sealing plug or a sealing gasket to enhance the airtightness of the material and the elastomer in the bottle cap inner cylinder. The sealing plug or the sealing gasket is usually made of a rubber material, preferably made of silicone. The sealing plug or the sealing gasket includes a rubber material encapsulated on the sealing cap by an injection molding method to form an independent integral component. The sealing plug or the sealing gasket can also be made into a separate rubber accessory, and then the accessory is assembled on the sealing cap.

The most preferred opening component is a rubber plug component, or the most preferred opening component is a combination of a rubber plug component and a fixing component, and the rubber plug component has an opening or an opening channel of the bottle cap inner cylinder. The fixing component fixes the rubber plug component and assembles it at the head end of the bottle cap inner cylinder, so that the opening component has both airtightness to the bottle cap inner cylinder and stability after forming an assembly component.

[0019] If necessary, in order to enhance the mutual force between the bottle cap and the reverse rotation hindering device of the bottle cap inner cylinder, the contact force area of ​​the mutually matching reverse rotation hindering devices can be increased, and the setting position of the reverse rotation hindering device on the bottle cap inner cylinder can be combined and selected. For example, preferably, the reverse rotation hindering device is provided on the outer wall of the top of the rear end of the bottle cap inner cylinder or the outer wall of the sealing cover of the bottle cap inner cylinder, or the rear end of the bottle cap inner cylinder is arranged into a connected annular cylinder, and the reverse rotation hindering device is provided on the outer wall of the annular cylinder, or a circular ring-shaped plane structure perpendicular to the central axis of the bottle cap inner cylinder is provided on the outer wall of the rear end of the bottle cap inner cylinder, and the reverse rotation hindering device is provided on the top surface of the plane structure.

[0020] The rotation preventing device refers to a convex setting on the outer wall of the inner cylinder cap, and a concave setting on the inner wall of the bottleneck of the main bottle body, and the two are matched with each other, or the rotation preventing device refers to a concave setting on the outer wall of the inner cylinder cap, and a convex setting on the inner wall of the bottleneck of the main bottle body, and the two are matched with each other, which can relatively fix the inner cylinder cap and the bottleneck of the main bottle body, prevent the inner cylinder cap and the bottleneck of the main bottle body from rotating relative to each other, or at least prevent the inner cylinder cap and the bottleneck of the main bottle body from rotating relative to each other in one direction; preferably, the concave or convex setting includes a serrated, sheet-shaped, oblique sheet-shaped or inverted setting, or a setting with a concave or convex functional structure formed by a serrated, sheet-shaped, oblique sheet-shaped or inverted member;

[0021] The elastomer includes a combination of compressed gas, a spring and a rubber plug or a combination of compressed gas and a rubber plug. Preferably, the elastomer is a compressed gas, wherein the compressed gas is preferably compressed air, compressed nitrogen, compressed carbon dioxide or compressed oxygen, etc. When the elastomer is a compressed gas or a combination of compressed gas and a rubber plug, the pressure of the compressed gas is greater than 0.11MPa. For example, the pressure of the compressed gas is 0.11MPa, 0.12MPa, 0.13MPa, 0.14MPa, 0.15MPa, 0.17MPa, 0.2MPa, 0.22MPa, 0.25MPa, 0.28MPa, 0.3MPa, 0.33MPa, 0.35MPa, 0.37MPa, 0.4MPa, 0.42MPa, 0.45MPa, 0.47MPa, 0.5MPa, 0.53MPa, 0.55MPa , 0.6MPa, 0.62MPa, 0.65MPa, 0.68MPa, 0.7MPa, 0.72MPa, 0.75MPa, 0.77MPa, 0.8MPa, 0.83MPa, 0.85MPa, 0.9MPa, 0.92MPa, 0.95MPa, 0.97MPa, 1MPa, 1.1MPa, 1.2MPa, 1.3MPa, 1.4MPa, 1.5MPa, 1.6MPa, 1.7MPa, and so on. When the elastic body adopts compressed gas, the compressed gas directly acts on the second material or more materials to squeeze the second material or more materials into the inner cylinder of the bottle cap; when the elastic body adopts a combination of a spring and a rubber plug, one end of the spring contacts or is subjected to force on the sealing of the bottle cap or the inner cylinder of the bottle cap, and a spring base can be provided at the inner surface of the bottle cap or the inner cylinder of the bottle cap where the sealing is in contact with the spring as needed, so as to facilitate the compression and stability of the spring and the release of the elastic force, and the other end of the spring contacts the rubber plug, and the elastic force generated by the compression of the spring acts on the rubber plug to squeeze the second material or more materials into the inner cylinder of the bottle cap; when the elastic body adopts a combination of compressed gas and a rubber plug, the compressed gas is sealed in the inner cylinder of the bottle cap and contacts one end of the sealing of the bottle cap or the inner cylinder of the bottle cap, and the force generated by the compressed gas acts on the rubber plug to squeeze the second material or more materials into the inner cylinder of the bottle cap;

[0022] The material 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. Preferably, at least one of the first material, the second material, and more materials is a liquid material, for example, both the first material and the second material are liquid materials, or the first material is a solid material and the second material is a liquid material, or the first material is a liquid material and the second material is a solid material, and the liquid material includes a water-soluble liquid material or a fat-soluble liquid material.

[0023] It should be understood that when there is no separated chamber in the bottle cap inner cylinder, the bottle cap inner cylinder itself can be regarded as having only one chamber and can only accommodate one type of material; when separated chambers are provided in the bottle cap inner cylinder, each chamber has an opening, and the opening is located at the head end of the bottle cap inner cylinder.

[0024] Furthermore, the inner cylinder of the bottle cap can be divided into at least two chambers to achieve the independent sealing, storage and release of the second material or more materials. For example, it can accommodate the second material, the third material, the fourth material, the fifth material, the sixth material, etc. that are independent and sealed to each other, so as to meet the stability requirements or comprehensive blending requirements of various materials. Preferably, the inner cylinder of the bottle cap is divided into two independent chambers to accommodate the second material and the third material respectively, and the head end of the inner cylinder of the bottle cap is provided with the outlet of each chamber, and at least one outlet is also provided on the cap of the inner cylinder; Preferably, the inner cylinder of the bottle cap is divided into three independent chambers to accommodate the second material, the third material and the fourth material respectively, and the head end of the inner cylinder of the bottle cap is provided with the outlet of each chamber, and at least one outlet is also provided on the cap of the inner cylinder;

[0025] The number of outlets of each chamber of the inner barrel of the bottle cap is at least one, preferably each chamber has one outlet, and the number of outlets of the inner barrel cap is at least one, and the number of outlets of the inner barrel cap can be the same as the number of outlets of all chambers, or can be different. The function and significance of such a setting is that the outlet of the chamber and the outlet on the inner barrel cap can overlap and stagger at different rotation angles and different positions, so that when opening the packaging container or twisting the bottle cap, the bottle cap can control the order of releasing materials in each chamber at different twisting angles or ranges, which can not only realize the diversification and novelty of material release, but also make the preparation of each material more accurate and scientific. For example, when the inner cylinder cap has only one outlet, when the bottle cap inner cylinder and the inner cylinder cap rotate relative to each other, the outlets on each chamber of the bottle cap inner cylinder can overlap with the outlet on the inner cylinder cap in sequence, so that the materials in each chamber are released in sequence; for another example, when the number of outlets of the inner cylinder cap is the same as the number of outlets of all chambers, when the bottle cap inner cylinder and the inner cylinder cap rotate relative to each other, the outlets on the chambers of the bottle cap inner cylinder can overlap with the outlets on the inner cylinder cap at the same time or with a delay, so that the materials in the chambers are released at the same time or with a delay.

[0026] The tail end of the bottle cap inner cylinder may be equipped with a sealing cap. After the material is filled into the chamber of the bottle cap inner cylinder, the tail end of the bottle cap inner cylinder and the chamber therein are sealed by the sealing cap. Preferably, the sealing cap has a sealing plug or a sealing gasket to enhance the sealing performance of the material and the elastomer in the bottle cap inner cylinder or the chamber. The sealing plug or the sealing gasket is usually made of a rubber material, preferably made of silicone. The sealing plug or the sealing gasket includes a method of encapsulating the rubber material on the sealing cap by injection molding to form an independent integral component. The sealing plug or the sealing gasket can also be made into a separate rubber accessory, and then the accessory is assembled to the sealing cap.

[0027] Alternatively, the rear end of the bottle cap inner cylinder is the same as the cylinder body, preferably the same integral component, for example, the rear end of the bottle cap inner cylinder and the cylinder body are preferably an integral injection molded part, the bottle cap inner cylinder is equipped with an opening component, the opening component can be assembled at the head end of the bottle cap inner cylinder, and the opening component has a chamber opening or an opening channel, preferably the opening component has a rubber pad or a rubber plug to facilitate the sealing of the opening component and the bottle cap inner cylinder, the rubber pad or the rubber plug is usually made of rubber material, preferably made of silicone; the rubber pad or the rubber plug includes a method of using injection molding to encapsulate The rubber material is coated on the opening component to form an integral and independent opening component. The rubber pad or rubber plug can also be made into a separate rubber accessory, and then the accessory is assembled to the opening component. The most preferred opening component is a rubber plug component, or the most preferred opening component is a combination of a rubber plug component and a fixing component, and the rubber plug component has an opening of a chamber or an opening channel. The fixing component fixes the rubber plug component and assembles it on the head end of the bottle cap inner tube, so that the opening component has both airtightness to the bottle cap inner tube or chamber and stability after forming an assembled accessory.

[0028] As needed, it is preferred that the tail end of the bottle cap inner cylinder is connected to the bottle cap in a snap-fit ​​manner. After the connection, the bottle cap inner cylinder and the reverse rotation hindering device on the bottle cap can contact or realize the function of matching each other, and the bottle cap inner cylinder and the bottle cap can rotate with each other. For example, it is preferred to adopt a snap-fit ​​connection between a convex buckle provided on the bottle cap inner cylinder and a convex buckle provided on the bottle cap, or adopt a snap-fit ​​connection between a convex buckle provided on the bottle cap inner cylinder and a concave buckle groove provided on the bottle cap, or adopt a snap-fit ​​connection between a concave buckle groove provided on the bottle cap and a convex buckle provided on the bottle cap.

[0029] If necessary, a sealing cap is provided at the tail end of the inner cylinder of the bottle cap. After the second material or more materials are respectively filled into the inner cylinder of the bottle cap or the inner cylinder chamber and the elastomer is placed, the inner cylinder of the bottle cap or the inner cylinder chamber is sealed with the sealing cap, so that the material and the elastomer in the inner cylinder of the bottle cap are independently sealed, or different materials in the inner cylinder chamber are independently sealed with the elastomer. Preferably, the sealing cap of the inner cylinder of the bottle cap has a sealing plug or a sealing gasket and can be fixed at the tail end of the inner cylinder of the bottle cap. The sealing plug or the sealing gasket is usually made of rubber material, preferably made of silicone.

[0030] The bottle cap is preferably in the shape of a convex top, and its advantages and importance are: it is convenient for the bottle cap and the rear end of the inner tube of the bottle cap to be connected and stabilized; it is also beneficial for the distribution of relevant settings or components on the inner wall of the bottle cap; it is also beneficial for expanding the volume of the inner tube of the bottle cap to accommodate more materials; of course, it is also beneficial for separating more chambers in the inner tube of the bottle cap to accommodate more different types of materials, and it is also beneficial for the assembly operation of the mutual connection and sealing of the bottle cap thread and the thread of the bottleneck of the main bottle body.

[0031] Further, as needed, as will be understood by those skilled in the art, a circle of dot-shaped connection circles with anti-theft opening functions may be provided at the bottom of the periphery of the bottle cap, and the dot-shaped connection circles are connected to the bottle cap by means of contacts and form an integral component with the bottle cap. When the bottle cap is opened, the dot-shaped connection circles are blocked by the outside of the bottleneck, and the dot-shaped connection circles are separated from the bottle cap, thereby playing an anti-theft opening function.

[0032] If necessary, a layer of gasket can be provided on the inner surface of the bottle cap in contact with the bottle mouth of the main bottle body to ensure the sealing between the bottle mouth of the main bottle body and the bottle cap. 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 bottle cap by a glue dripping method.

[0033] The size of the outlet of the inner cylinder of the bottle cap and the outlet of the inner cylinder cap can be set according to the state of the released material. For liquid materials with good fluidity, the outlet of the inner cylinder of the bottle cap and the outlet of the inner cylinder cap 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 inner cylinder of the bottle cap and the outlet of the inner cylinder cap or their channels should be set larger to facilitate the smooth release of the materials.

[0034] The outlet of the inner cylinder of the bottle cap and the outlet of the inner cylinder cap or the channel thereof 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 inner cylinder of the bottle cap and the outlet of the inner cylinder cap or the channel thereof are designed into various shapes so that the liquid material presents different shapes when released, including water column or liquid column, spray, etc.

[0035] Further, as needed, at least one mutually matching rib or stopper may be provided on the inner wall of the inner tube cap and the outer wall of the bottle cap inner tube in a direction parallel to the central axis of the inner tube cap or the bottle cap inner tube, as a rotation positioning rib or rotation positioning stopper of the inner tube cap and the bottle cap inner tube, for positioning the outlet of the inner tube cap and the outlet of the bottle cap inner tube at a specific position when they are misaligned or overlapped during the mutual rotation process. The rib or stopper is a convex or concave arrangement provided on the inner wall of the inner tube cap and the outer wall of the bottle cap inner tube, and the arrangement includes strips, columns, , sheet-like or groove track-like arrangement, the ribs or buckles arranged on the inner wall of the inner cylinder cap and the outer wall of the inner cylinder of the bottle cap match each other, the purpose of which is that when the inner cylinder cap and the inner cylinder of the bottle cap 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 can prevent the inner cylinder cap and the inner cylinder of the bottle cap 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 provide stability guarantee for the safe storage of the material in a sealed state;

[0036] Preferably, when the inner cylinder cap and the bottle cap inner cylinder are rotated to the rib or buckle position, the outlet on the bottle cap inner cylinder is staggered with the outlet on the inner cylinder cap at a preset position, so as to facilitate the sealing and preservation of the material, or the outlet on the bottle cap inner cylinder is overlapped with the outlet on the inner cylinder cap, so as to facilitate the release of the material, or when the inner cylinder cap and the bottle cap inner cylinder are rotated to the rib or buckle position, the inner cylinder cap and the bottle cap inner cylinder can no longer rotate relative to each other or cannot be easily rotated, and the outlet of the inner cylinder cap is staggered with the outlet of the bottle cap inner cylinder, so as 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 this vibration or sound will be felt by the user when opening the packaging container or twisting the bottle cap, so as to facilitate the user to control the hand feel when opening the packaging container or twisting the bottle cap. For example, a rib is provided on the outer wall of the inner cylinder of the bottle cap, and when the outlet of the inner cylinder of the bottle cap is misaligned with the outlet of the inner cylinder cap, the rib is in the middle position of the two ribs provided on the inner wall of the inner cylinder cap, so that the inner cylinder cap and the bottle cap inner cylinder 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 inner cylinder of the bottle cap, and when the outlet of the inner cylinder of the bottle cap coincides with the outlet of the inner cylinder cap, the rib is in the position of a rib provided on the inner wall of the inner cylinder cap, and the two ribs contact each other and hinder the rotation, so that the inner cylinder cap and the bottle cap inner cylinder can no longer rotate with each other or cannot be easily rotated, so as to prevent the disadvantage that the retention time of the outlet overlap is too short and the material cannot be completely released, which is conducive to the smooth and complete release of the material;

[0037] In addition, on the one hand, the setting of the above-mentioned ribs or buckles can accurately control the range of mutual displacement or overlap between the outlet of the inner tube of the bottle cap and the outlet of the inner tube cap. On the other hand, this setting enables the external thread on the bottleneck of the main bottle body and the internal thread on the bottle cap to better coordinate or cooperate with the rhythm of opening the packaging container and mixing the materials when tightening or unscrewing the circular motion and up and down motion, or even when the bottle cap falls off the bottle mouth. Thirdly, when the inner tube of the bottle cap and the inner tube cap rotate relative to each other, this device can avoid multiple, unnecessary displacement or overlap between the outlet on the inner tube of the bottle cap and the outlet on the inner tube cap. The ribs or buckles determine the moving range of the outlet on the inner tube of the bottle cap and the outlet on the inner tube cap when they are displaced or overlapped.

[0038] Those skilled in the art can understand that the various components, devices, settings, etc. of the packaging container described in the present invention are preferably assemblies or combinations of the various components described in the present invention; of course, those skilled in the art can understand that when some components are produced, such as by injection molds, there are high difficulties, low production efficiency or high production costs, the various components described in the present invention can be obtained by assembling, connecting, fixing or welding individual parts. Undoubtedly, the packaging container described in the present invention, no matter how it is assembled or assembled, belongs to the protection scope of the present invention.

[0039] In particular, the concave or convex setting on the inner wall of the bottleneck of the main bottle body, that is, the rotation preventing device of the bottleneck of the main bottle body, can be an independent component of the main bottle body. The components with the concave or convex setting are assembled and fixed in the inner cavity of the bottleneck to form an assembly. Alternatively, a concave or convex structure can be made on the inner wall of the bottleneck of the main bottle body so that the inner wall of the bottleneck of the main bottle body has the rotation preventing device.

[0040] The bottle cap is preferably an independent integral component. For example, when a convex bottle cap is used, it is preferably prepared into an independent integral component by injection molding. In particular, the protruding part of the bottle cap and the side of the bottle cap can also be made into separate accessories respectively, and then assembled. For example, when a convex bottle cap is used, a reverse rotation hindering device can be provided on the separate accessory on the top of the bottle cap, and a snap device can be provided on the separate accessory on the side of the bottle cap.

[0041] On the other hand, the technical solution of the packaging container described in the present invention is that when the user or consumer opens the packaging container or only needs to twist the bottle cap, the independently sealed contents in the packaging container can be automatically mixed together to achieve the effect of automatic mixing. The materials therein can be automatically mixed without affecting the operation of tightening the container cap after filling the material, nor does it affect the operation of the user to tighten the bottle cap after unscrewing the bottle cap. Its main function is that a reverse rotation hindering device and a rotation preventing device are provided on the container neck and the bottle cap component. The bottle cap component is equivalent to an accessory component of a container cap. Therefore, further, the present invention further provides a packaging container including a main bottle body, a bottle cap and a bottle cap accessory component.
