Description

Technical Field The present invention relates to the field of product packaging containers, and specifically to a cover component of a container closure device, which can be used as a core component of the container closure device; the container closure device is a closed container device that can contain and seal target materials, and the container closure device can release the contained and independently sealed materials into the container to achieve the automatic mixing of various materials before opening the packaging container, or to achieve the automatic mixing and blending effect of a packaging container.

[0001] The cover component can enable the container closure device to achieve accurate positioning, stopping, and locking control operations, and realize the anti-theft opening function of the container closure device. Background Art In many applications such as the mixing of different materials, it is necessary to discharge or release the material and mix it into another material shortly before using the material mixture. It is usually impossible or undesirable to store products in a pre-mixed form because when the products are stored as a mixture for a period of time, they may react with each other undesirably or cause the quality of the mixture to deteriorate. A common example is, for example, two or more pharmaceutical components, which have better stability and longer shelf life when not mixed than when mixed.

[0002] Of course, it can also be applied to other liquids, liquid-solid, liquid-liquid mixtures, such as water, alcoholic beverages, other beverages, other solvents or solutions, and oily liquids, etc. During the shelf life of the product, two or more different materials in the product need to be stored separately to make it more conducive to the stability, freshness, functional 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 together when used, which can easily cause many unfavorable factors such as inconvenience in carrying, inconvenience in use, and easy to cause secondary pollution.

[0003] International patent application WO2007 / 129116 and international patent application WO2012 / 175934 disclose a container closing device, in which a fluid chamber is arranged in a cover member, and a plug member is driven by lifting the shell to open the opening of the fluid chamber, thereby introducing the contents in the cover member into the container; however, the above-mentioned known technical solutions have the following disadvantages: (1) The structural arrangement of the cover member can only be used to seal liquid materials, and the plug member is difficult to seal solid materials, and the fluid chamber needs to be pressurized to release the liquid material; (2) Due to the presence of the plug member, the contents are released after being released. , a large amount of contents will remain in the cover member, resulting in incomplete release of the contents; (3) when the container closure device is opened to release the contents into the container, the container neck opening is also opened at the same time, and the sealing of the container is destroyed at the same time, which cannot meet the requirements of still needing to seal the contents after mixing and further disposing of the mixture; (4) there are defects in the repeated use of the packaging container during rotational opening, the accurate positioning and coordination of the twisting displacement of the cover member and the release of the material, and the control performance is poor; (5) it is difficult to realize the anti-theft opening function of the cover member when it is twisted; (6) the structural components are numerous and complex, and the degree of industrial assembly is low. Summary of the invention In order to overcome the shortcomings of the prior art, the present invention provides a container closure device with a simple structure, easy to twist and open operation control, suitable for being assembled with other components to form various structures, and a cover component with an anti-theft opening structure. For example, it can be assembled with a material cavity tube with a funnel shape to form a container closure device, or assembled with a material cavity tube with a piston pressing structure to form a container closure device, or assembled with a material cavity tube with a sealing plug valve to form a container closure device, and so on.

[0004] The present invention adopts the following technical solutions.

[0015] For example, a convex-concave structure is provided on the inner wall of the rear end of the cover tube structure;

[0016] For example, a convex-concave structure is provided on the cover surrounding structure.

[0017] The positioning control mechanism provided at the head end and / or the tail end of the cover component of the present invention can match with the positioning control mechanism of another component, for example, the above-mentioned structure matches with the positioning control mechanism provided at the head end and / or the tail end of the material chamber, wherein mutual matching refers to being able to engage with each other, or properly engage with each other, thereby producing mutual contact, blocking and other effects, and having a mutual matching effect or matching state; in addition, the blocking effect includes two concepts of blocking or hindering. Blocking refers to being blocked and stopping relative movement, and hindering refers to being blocked, and the relative movement may be stopped, or it may not be blocked, and relative movement can still occur after breaking through the blocking effect.

[0018] On the other hand, the positioning control mechanism at the front end of the cover member includes a stopping mechanism or a locking mechanism that can engage with another component that contacts the cover member, and the stopping mechanism engages when the cover member rotates to a predetermined position relative to the other component to prevent further relative rotation of the cover member and the other component; the locking mechanism engages when the cover member rotates to a predetermined position relative to the other component to hinder further relative rotation of the cover member and the other component, and the hindering of further relative rotation of the cover member and the other component includes an obstructing effect between the cover member and the other component, and increasing the force of mutual rotation can cause relative rotation between the cover member and the other component; for example, the stopping mechanism or the locking mechanism is arranged at any contactable position between the front end of the cover tube structure and the front end of the material chamber tube, and the stopping mechanism at the front end of the cover member and the stopping mechanism arranged at the front end of the material chamber tube can engage with each other, and the locking mechanism at the front end of the cover member and the locking mechanism arranged at the front end of the material chamber tube can engage with each other.

[0019] On the other hand, the positioning control mechanism at the rear end of the cover member includes a stop mechanism or a locking mechanism that can engage with another component that contacts the cover member, and the stop mechanism engages when the cover member rotates to a predetermined position relative to the other component to prevent further relative rotation of the cover member and the other component; the locking mechanism engages when the cover member rotates to a predetermined position relative to the other component to hinder further relative rotation of the cover member and the other component, and the hindering of further relative rotation of the cover member and the other component includes an obstruction effect between the cover member and the other component, and increasing the force of mutual rotation can cause relative rotation of the cover member and the other component; for example, the stop mechanism or the locking mechanism is arranged at any contactable position between the rear end of the cover member and the rear end of the material cavity tube, or the stop mechanism or the locking mechanism is arranged at any contactable position between the rear end of the cover member and the rear end of the screwing mechanism, the stop mechanism at the rear end of the cover member and the stop mechanism arranged at the rear end of the material cavity tube can engage with each other, and the locking mechanism at the rear end of the cover member and the locking mechanism arranged at the rear end of the material cavity tube can engage with each other; the rear end of the cover member includes the rear end of the cover tube structure or the cover surrounding structure.

[0020] Preferably, the positioning control mechanism provided on the cover member, its stop mechanism or locking mechanism can be a setting of one or more structures, and it is particularly preferred to be a setting of two structures distributed in symmetrical positions. For example, two convex-concave stopper structures, convex-concave blocking structures or convex-concave groove structures provided at mutually symmetrical positions on the head end of the cover member match with two convex-concave stopper structures, convex-concave blocking structures or convex-concave groove structures provided at mutually symmetrical positions on the head end of the material cavity, and can rotate with each other to produce an engagement or blocking effect. For example, two convex-concave stopper structures, convex-concave blocking structures or convex-concave groove structures provided at mutually symmetrical positions on the tail end of the cover member match with two convex-concave stopper structures, convex-concave blocking structures or convex-concave groove structures provided at mutually symmetrical positions on the tail end of the material cavity, and can rotate with each other to produce an engagement or blocking effect.

[0021] The cover tube outlet is located at the center position or eccentric position of the head end of the cover tube structure. Preferably, the cover tube outlet is not located at the center position of the head end of the cover tube structure, but is located away from the center.

[0022] If necessary, a sealing plug or a sealing gasket is provided on the inner wall of the head end of the cover tube structure and the surrounding area of ​​the cover tube outlet to enhance the sealing performance of the cover tube outlet. The sealing plug or the sealing gasket is usually made of rubber material, preferably silicone, butyl rubber or thermoplastic rubber;

[0023] The sealing plug or sealing gasket includes a method of coating the inner wall of the head end of the cover tube structure with a rubber material by injection molding; or a method of coating the inner wall of the head end of the cover tube structure with a layer of rubber pad by dripping glue; or the sealing plug or sealing gasket can be made into a separate rubber material accessory, and then the accessory is installed on the inner wall of the head end of the cover tube structure, but no matter which method is used, the cover tube outlet must be unobstructed. The sealing gasket or sealing plug is usually made of rubber material, preferably made of silicone, butyl rubber or thermoplastic rubber.

[0024] It should be noted that regarding the concepts of the head end and the tail end of the cover member, cover tube structure or other components, the head end of the cover member, cover tube structure or other components 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.

[0025] Furthermore, the rear end of the cover member of the container closure device of the present invention has an anti-theft opening structure for protecting the container closure device from theft and preventing it from being accidentally opened. The rear end of the cover member includes the rear end of the cover tube structure or the cover surrounding structure, that is, the rear end of the cover tube structure or the cover surrounding structure is provided with an anti-theft opening structure for protecting the container closure device from theft and preventing it from being accidentally opened. Preferably, a serrated structure is provided at the rear end of the cover member, and the serrated structure can be engaged with the serrated structure of another component, so that the cover member and the other component generate mutual resistance when they rotate relative to each other, and further break the easy-tear connection ring on the other component, thereby playing the role of anti-theft opening. The easy-tear connection ring on the other component is connected to the component by contact connection or micro-connection, and forms an integral component with the component. For example, the other component is preferably a screwing mechanism or a material cavity that can be interconnected with the cover member, which is described in detail in the embodiments and drawings of the present invention. The rear end of the cover member includes the rear end of the cover tube structure or the cover surrounding structure;

[0026] Alternatively, an easy-to-tear connection ring is provided at the rear end of the cover member, and the easy-to-tear connection ring has a serrated structure. The easy-to-tear connection ring can engage with the serrated structure of another component through its serrated structure, so that the cover member and the other component generate mutual resistance when they rotate relative to each other, and further cause the easy-to-tear connection ring on the cover member to break, thereby playing a role in preventing the cover from being opened by theft. The easy-to-tear connection ring is connected to the cover member by contact connection or micro-connection, and forms an integral component with the cover member. The rear end of the cover member includes the rear end of the cover tube structure or the cover surrounding structure.

[0027] Further, as needed, a circle of easy-to-tear connecting ring with anti-theft opening function can be set at the front end of the outer periphery of the cover surrounding structure. The easy-to-tear connecting ring is connected to the cover surrounding structure by contact connection or micro-connection, and forms an integral component with the cover surrounding structure. When the container closing device is installed on the container neck and the container needs to be opened and the cover surrounding structure is twisted or rotated, the easy-to-tear connecting ring is blocked by the container neck, and its point-connected contacts or micro-connections are broken, so that the easy-to-tear connecting ring is separated from the cover surrounding structure, thereby playing a role in anti-theft opening.

[0028] The various components, members, mechanisms, devices, settings, etc. of the cover member described in the present invention can be obtained by assembling, connecting, fixing, bonding or welding of individual parts. Of course, it can be understood by those skilled in the art that when certain components are produced, such as by injection molds, there are situations of high difficulty, low production efficiency or high production cost, or the injection mold cannot realize its structure, the various components described in the present invention can be obtained by assembling, connecting, fixing or welding of individual parts. Undoubtedly, the cover member described in the present invention, no matter how it is assembled, installed or assembled, belongs to the protection scope of the present invention.

[0029] For example, it is preferred that the cover surrounding structure and the cover cylinder structure are an independent integral component, or the cover surrounding structure and the cover cylinder structure are independent components, and the cover surrounding structure and the cover cylinder structure are assembled and fixed together to form a cover member, and the fixing method includes, but is not limited to, snap-fit ​​fixing, threaded fixing, welding fixing, adhesive bonding fixing, etc. It is most preferred that the cover surrounding structure and the cover cylinder structure are made into an independent plastic member by injection molding.

[0030] It is particularly noted that the cover member of the present invention can be made of polymer materials, metals, glass, ceramics, aluminum-plastic composite materials, paper-plastic materials, etc., or composite functional materials of the above materials, or the cover member is an assembly of different parts made of various materials. It is preferably made of polymer materials such as plastics, rubber, and plastic materials, or made of metal materials such as steel, aluminum, tin, copper and other metals or composite metals, or made of glass and ceramic materials. For example, polymer materials include but are not limited to polypropylene (PP), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyethylene terephthalate (PET), polyethylene (PE), polyvinyl chloride (PVC), polycarbonate (PC), polystyrene (PS), as well as paper-plastic composite materials, aluminum-plastic composite materials, etc., but the material is not limited to any specific one.

[0031] Furthermore, the cover member provided by the present invention is used in the preparation of a container closing device. The cover member is assembled with other components, such as two or more components of a material chamber, a screwing mechanism, a piston, a sealing plug gasket, a control mechanism, etc. to form a container closing device. The container closing device can be installed on a container neck with an opening to seal the container and form a packaging container. The packaging container can be used to package and store the following products: food or beverages, drinking wine, health food, special medical formula food, ordinary food, medicine, medical equipment, sanitary products, cosmetics or daily necessities, especially for packaging and storing beverages, drinking wine, health food, special medical formula food, ordinary food, medicine, medical equipment, sanitary products, cosmetics or daily necessities containing liquid materials.

[0032] The cover member provided by the present invention can be easily assembled with other components to form container closure devices of various structural modes, and has an anti-theft opening structure, for example, it can be assembled with a material cavity tube with a funnel shape to form a container closure device, or assembled with a material cavity tube with a piston pressing structure to form a container closure device, or assembled with a material cavity tube with a sealing plug valve to form a container closure device, and so on.

[0033] On the one hand, the container closure device assembled with the cover member of the present invention is convenient to use, simple to operate and accurate to control. The positioning control mechanism of the cover member of the present invention is arranged at the head end or the tail end of the cover member, which is conducive to the rotation operation and positioning control of the container closure device. The positioning control mechanism at the head end of the cover member is close to the cover cylinder outlet, which can effectively control the accuracy of the cover member and other assembly parts during the rotation operation. The positioning control mechanism at the tail end is conducive to the rotation operation, avoiding the centrifugal rotation or eccentric rotation of the cover member and other assembly parts due to material deformation, matching errors between parts, and changes in the conduction of the force when rotating with each other, thereby avoiding errors and uncontrollability in operation.

[0034] On the other hand, the positioning control mechanism provided in the cover member of the present invention can prevent the cover member and other assembly components from rotating relative to each other or being easily rotated, thereby providing accurate positioning of the position and control of the release time for the full release of the material, as well as ensuring the safe storage of the material in a sealed state, which is beneficial to the accurate positioning, stopping and locking control operations of the cover member.

[0035] In addition, the cover member of the present invention has a structure that prevents the cover member from being opened by theft, which is of great significance to the safe storage, use and trading and circulation of the product.
