Description

Technical Field

[0001] The utility model relates to the technical field of wine packaging, in particular to a shutter device in wine packaging and a wine packaging body containing the shutter device. Background Art

[0002] Wine plays an important role in modern life. As it is in liquid form, it is often packaged for convenience when it is sold. The usual method is to use glass containers to fill the wine. In order to make the wine look more upscale, wine manufacturers often need to package it again outside the glass container filled with wine.

[0003] In daily life, there are many kinds of wine. For consumers, the first thing that comes into their eyes is often the outermost packaging box of the wine, rather than the actual wine itself. Therefore, the packaging of wine plays a very important role in the sales of wine, especially in attracting consumers' attention.

[0004] The existing wine packaging, whether the first layer of the wine bottle itself or the second layer of paper, wood, plastic, metal and other materials, is generally sealed after packaging is completed, which is a static state and cannot provide consumers with additional fun and pleasure when consuming wine. At the same time, due to the demand for packaging, a fully enclosed method is often used. When consumers buy wine, they generally cannot check the color of the wine in the box. If they want to observe the color of the wine in the box, they often need to tear open the outer box. In this case, consumers cannot use this method of tearing open the box to check during the selection stage. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problems in wine packaging, and further provide a shutter device on the wine packaging body so that consumers can check the color or other patterns of the wine in the package without destroying the packaging body. In addition, it can also provide consumers with additional fun when consuming wine by setting prizes.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme. The shutter device adopted has a main body on the front and a chassis on the back. The fan blade assembly is located between the main body and the chassis, and the main body covers the fan blade assembly and the chassis. A plurality of column grooves are arranged on the inner side surface of the main body, which are coaxial with the column grooves and corresponding positioning grooves are arranged on the main body, and the middle of the main body is a hollow area. The fan blade assembly is composed of a plurality of fan blades, and when all the fan blades are fully closed, the middle hollow area of ​​the main body can be completely covered. A connecting rod and a limit block are arranged on each fan blade, and a fixed column is arranged at one end of the connecting rod, and the fixed column is fully fitted with the positioning groove on the main body.

[0007] A plurality of movable grooves are arranged on the chassis, and a hollow area is arranged in the middle of the chassis. A movable track is arranged along a circle of the movable groove on the side away from the fan blade assembly. The limit blocks on the fan blades can move back and forth along the movable track in the movable groove. The positions and numbers of the movable grooves and column grooves match the positions and numbers of the fan blades of the fan blade assembly.

[0008] When each blade of the fan blade assembly is in a fully closed state, the front end of the blade points to the center of the hollow area in the middle of the shutter, and the limit block is located at the rear end of the blade. The limit block is set to ensure that it will not rotate in the moving groove of the chassis. A fixing hole is set at the rear end of the blade, and the center of the fixing hole is located in the direction of movement of the limit block on the moving groove of the chassis. A cylindrical protrusion is set at one end of the connecting rod close to the blade. The cylindrical protrusion is perpendicular to the connecting rod and can be completely embedded in the fixing hole and can rotate freely in the fixing hole.

[0009] The fixed column is perpendicular to the connecting rod, and a roller is mounted on the end of the fixed column away from the positioning groove. The roller can rotate freely around the fixed column but does not separate from the fixed column. The width of the end face of the limit block at the end away from the fan blades is greater than the opening width of the movable groove. The direction of the movable groove coincides with the tangent of the circle formed by the projection of the hollow area in the center of the vertical body. The length of the movable groove is sufficient to fully open or close all the fan blades. The outer diameter of the chassis is smaller than the inner diameter of the body. The movable groove on the chassis is provided with a movable track along the opening of the movable groove on the side away from the fan blade assembly. The limit block on the fan blade is embedded in the movable groove and moves back and forth along the movable track. A bottom plate is provided on the chassis, and part of the bottom plate protrudes in the direction away from the fan blade assembly, that is, it is higher than the plane where the movable groove and the lower surface of the body facing the chassis are located.

[0010] A handle is provided on the body, and an opening with an internal thread is provided on the body, which matches the external thread provided at one end of the handle, and a protrusion for easy screwing is provided at the other end of the handle. The length by which the handle can be screwed into the body is greater than the distance between the outer wall of the body and the outer wall of the chassis, so as to facilitate locking the body and the chassis.

[0011] When the wine packaging body is a wine bottle, the shutter device is arranged on the front of the wine bottle. When the wine packaging body is a wine bottle packaging box, the shutter device is arranged on the front of the packaging box. In this case, the handle of the shutter device is provided with a protection mechanism. Only after the protection mechanism is destroyed can the handle be twisted to release the body and the chassis and open the shutter.

[0012] In order to better understand the technical solution of the utility model, it is described in detail as follows:

[0013] The shutter device of the utility model has a circular structure as a whole, and is mainly composed of a body, a chassis, a fan blade assembly, a handle, a decorative surface and other components.

[0014] The fan blade assembly is located between the main body and the chassis, and the main body covers the fan blade assembly and the chassis. During installation, the main body, the fan blade assembly and the chassis can be completely fitted together to form a circular whole of the shutter device of the utility model.

[0015] The center positions of the body and the chassis are concentric circular hollow structures, and the circular radius of the central hollow of the chassis is greater than or equal to the circular radius of the central hollow on the body. The fan blade assembly is composed of a plurality of fan blades, and each fan blade forms a closed circle after closing each other, and the center of the closed circle coincides with the center of the central hollow of the body and the chassis. The area of ​​the circular fan blade surface formed when all the fan blades on the fan blade assembly are fully closed is greater than or equal to the area of ​​the circular hollow in the center of the body.

[0016] The design of the above structure is mainly to ensure that after all the blades of the fan blade assembly are fully opened, the central area of ​​the main body, the fan blade assembly and the chassis is a completely hollow structure without any obstruction.

[0017] The decorative surface is the upper surface of the annular area on the front side of the main body, and various graphics or patterns can be provided to increase its beauty.

[0018] The core structure of the shutter device of the utility model is a fan blade assembly, which is composed of a plurality of fan blades with the same structure. The number of fan blades is determined by the area of ​​the hollow area in the middle of the body and the size of the fan surface of a single fan blade, as long as all the fan blades are fully aligned to completely cover the hollow area in the middle of the body.

[0019] Each blade in the fan blade assembly has the same shape, and the parts connected to each blade are also the same. When the blade is in a fully closed state, its front end points to the center of the hollow area in the middle of the shutter. A limit block is set on the side of the rear end of the blade facing the chassis and close to the edge of the rear end surface. One or more limit blocks can be set, and two are preferably set. When 2 or more limit blocks are set, the limit blocks can be cylindrical or cube-shaped, preferably cylindrical, and the centers of all limit blocks are located on the same straight line and coincide with the tangent of the circle formed by the projection of the hollow area in the center of the vertical body.

[0020] A fixing hole is arranged on the other side of the same straight line of the limit block.

[0021] When only one stop block is provided, in order to prevent the stop block from rotating in the moving groove on the chassis, the stop block is in a square shape, preferably a rectangular parallelepiped shape. The center of the fixing hole is located in the direction in which the stop block moves on the moving groove on the chassis. The fixing hole vertically penetrates the fan blade to the other side of the fan blade away from the chassis.

[0022] The side of the fan blade facing the chassis is called the back side, and the side of the fan blade away from the chassis is called the front side.

[0023] A connecting rod is arranged at the position of the fixing hole on the front side of the fan blade, and a cylindrical protrusion arranged on the side of one end of the connecting rod is completely embedded in the fixing hole, and the cylindrical protrusion and the connecting rod are perpendicular to each other. The cylindrical protrusion passes through the entire fixing hole to reach the back side of the fan blade. The cylindrical protrusion can rotate freely relative to the fan blade in the fixing hole, and the connecting rod can apply a force parallel to the surface of the fan blade to the fan blade through the cylindrical protrusion at one end of the connecting rod embedded in the fixing hole, thereby driving the movement of the fan blade.

[0024] A fixing column is provided at the other end of the connecting rod, the fixing column and the connecting rod are perpendicular to each other, and the fixing column runs through both sides of the connecting rod. A roller is provided on the fixing column on the side facing the back of the fan blade. The roller is sleeved on the fixing column, and the roller can rotate freely around the fixing column, but will not separate from the fixing column. The diameter of the roller at the end facing the back of the fan blade is larger than the diameter of the roller at other positions.

[0025] The main structure of the body includes column slots, positioning slots and a hollow area in the middle. The column slots are arranged on the inner side of the body, and the side facing the center of the body is open. The number, position and size of the column slots match the fixed column at one end of the connecting rod of the fan assembly, and the inner diameter of the column slots matches the diameter of the larger end face of the fixed column facing the chassis. The roller on the fixed column can rotate freely around the fixed column in the column slot space.

[0026] A positioning groove is set on the main body on the side of the column groove away from the fan blade assembly, coaxial with the column groove, and the position, number and size of the positioning groove are completely matched with the position, number and size of the fixing column at one end of the connecting rod of the fan blade assembly, and the fixing column can be completely embedded in the above-mentioned positioning groove.

[0027] When the fixing column and the positioning groove are completely installed in place, the end surface of the roller with a larger diameter facing one end of the fan blade assembly is flush with the end surface of the body facing the chassis.

[0028] When the main body rotates around the center of the main body, the connecting rod is driven by the fixing column embedded in the positioning groove on the main body, and then the fan blade is driven to move through the connecting rod.

[0029] The chassis is mainly composed of a bottom plate, a moving groove and a hollow area in the middle. The outer diameter of the chassis should be smaller than the inner diameter of the body. When the fan assembly, the body and the chassis are installed, the end surface of the roller with a larger diameter facing the chassis covers the outer edge of the chassis, which can buckle the chassis and ensure that the roller body set at one end of the connecting rod of the fan assembly can roll along the outer wall of the chassis.

[0030] The number and position of the moving grooves match the number and position of the fan blades, and a moving track is set along the circumference of the moving groove opening on the side of the moving groove away from the fan blade assembly. The moving groove is long and narrow, and the limit block located on the back of the fan blade is embedded in the moving groove. The end face width of the limit block away from the back of the fan blade is greater than the opening width of the above-mentioned moving groove to ensure that the limit block will not detach from the limit groove. The limit block can move along the moving track in the moving groove.

[0031] The setting direction of the mobile slot must meet the following requirements:

[0032] When the connecting rod of the fan blade is subjected to force, it drives the fan blade to move. Since the limit block is fixed to the fan blade, the limit block is restricted in the moving groove, that is, the movement of the connecting rod will drive the limit block to move on the moving track of the moving groove, so the direction of the moving groove will affect the moving direction of the fan blade. Therefore, the setting direction of the moving groove should ensure that when the limit block is in the initial position of the moving groove, all the fan blades are in a completely closed state, and when the limit block is completely moved to the other end of the moving groove, all the fan blades are in a completely open state. That is, when the limit block moves back and forth in the moving groove, all the fan blades will be in the process of opening or closing.

[0033] The bottom plate on the chassis is located in the area between the above-mentioned moving grooves. Part of the bottom plate is raised in the direction away from the fan blade assembly, that is, higher than the plane where the moving groove and the lower surface of the body facing the chassis are located. The raised part on the bottom plate is connected and fixed to the wine packaging body. The two can be fixed by magnetic connection or by strong adhesive bonding to each other, so that the shutter device is fixed to the wine packaging body, and it can ensure that when the body is manually rotated, there will be no interference with the wine packaging body.

[0034] The handle is arranged on the main body, and the handle is connected to the main body by a thread. An external thread is arranged on one end of the handle, and an internal thread is arranged on the inner side of the opening on the main body, and the external thread and the internal thread match each other. The opening runs from the outer side of the main body to the inner side of the main body. A protrusion is arranged on the other end of the handle for convenient left and right knob handles. When the handle is screwed in one direction, the threaded end of the handle is screwed into the inner side of the main body through the matching of the external thread on the other end of the handle and the internal thread on the opening on the main body. The length that the handle can be screwed into the inside of the main body is greater than the distance between the outer wall of the main body and the outer wall of the chassis, which can ensure that one end of the handle can reach the side wall of the chassis and can resist the chassis, thereby preventing the relative movement between the main body and the chassis.

[0035] When the other end of the handle is twisted in the opposite direction, the handle rotates in the opposite direction, and the threaded end of the handle gradually moves away from the chassis, thereby releasing the mutual locking between the body and the chassis.

[0036] The shutter device of the utility model is opened or closed in the following manner:

[0037] When the shutter is completely closed and needs to be opened, the handle can be twisted to move it away from the chassis to release the mutual lock between the body and the chassis. At this time, the body and the chassis can move freely relative to each other.

[0038] When the main body is manually screwed in one direction (the direction is determined by the orientation of the movable slot provided on the chassis), the main body will drive the movement of the connecting rod of the fan blade assembly through the fixed column in its positioning slot. The movement of the connecting rod will drive the roller on the fixed column in the column slot of the main body to rotate, and the roller will roll along the side wall of the chassis in the direction of the main body being screwed. At the same time, during the movement, the connecting rod will pull the fan blades to move through the cylindrical protrusion at the other end of the connecting rod that is completely embedded in the fixed hole. Since the limit block fixedly connected to the fan blade can only move along the movable track on the movable slot on the chassis, the movement direction of the fan blade is limited to the specified direction. At this time, all the fan blades move in the predetermined direction, gradually opening the middle hollow area of ​​the shutter device.

[0039] When the hollow area is fully opened, the main body is rotated in the opposite direction as mentioned above, and the moving parts all move in the opposite direction. At this time, all the fan blades gradually return to their original state until the hollow area in the middle is completely closed.

[0040] At this time, turn the handle in the opposite direction, screw one end of the handle to the outer wall of the chassis and lock it.

[0041] The utility model can control whether the shutter can be opened by twisting the control handle.

[0042] When the shutter device is set only for opening the fan blades to check the color of the wine or other patterns inside, the handle can be set to a free state, that is, anyone in any state can turn the handle to unlock the shutter and open the shutter for inspection. After the inspection, the shutter is closed and the handle is tightened and locked.

[0043] Of course, if the purpose of the manufacturer setting up the shutter device of the utility model is to give small gifts to consumers who buy wine to achieve the purpose of promotion, the position of the handle can be fixed by sticking a seal or the like when the handle locks the body and the chassis, and the seal or the like protection mechanism must be destroyed when the handle needs to be twisted. That is, only consumers who have purchased the packaged wine can destroy the above-mentioned seal-like protection mechanism, and then twist the handle to open the shutter and take out the gift inside.

[0044] The shutter device can be directly mounted on the wine bottle body, or directly mounted on the wine bottle packaging box body outside the wine bottle.

[0045] When the shutter device is directly mounted on the body of the wine bottle, the shutter device is mounted on the upper part of the front of the bottle body, and a wine information area is set below the shutter device, such as the name of the wine, the alcohol content of the wine, the volume of the wine, and the manufacturer or origin of the wine, etc. Consumers can open the shutter of the shutter device to see the pattern or other text set by the manufacturer in the shutter, such as a positive word, a short cultural story about wine, a funny joke, etc., so that consumers can have a certain amount of fun when consuming wine.

[0046] When the shutter device is installed on the wine bottle packaging box outside the wine bottle, if it is only for the purpose of installing the shutter on the wine bottle, the handle of the shutter device installed on the packaging box body does not need to be provided with a protective mechanism. If the manufacturer sets a storage space inside the shutter of the shutter device to place some promotional gifts, in order to limit the shutter to only consumers who have purchased the wine, it is necessary to set a protective mechanism at the handle position of the shutter device to seal the handle. The protective mechanism can be made of the same material as the packaging box and is set in an easily destructible manner. If the consumer wants to open the shutter, he can only destroy the protective mechanism before twisting the handle to open the shutter.

[0047] The beneficial effects of the utility model are:

[0048] 1. By setting the shutter structure of the utility model on the wine packaging, consumers can open the shutter and observe the color of the wine or other patterns set by the manufacturer from the outside without destroying the packaging when purchasing wine;

[0049] 2. By setting the shutter device of the utility model on the packaging of the wine and setting a certain accommodation space in the shutter device, consumers can see the prizes pre-set by the manufacturer in the shutter after purchasing, which provides consumers with additional fun;

[0050] 3. The shutter device of the utility model is arranged on the wine packaging body, which can improve the grade of the wine packaging, help to attract consumers, increase the added value of the product, further meet the spiritual needs of consumers, and consolidate the brand and corporate image.

[0069] Combined with Figures 1 to 12 The shutter device in this embodiment is a circular structure as a whole, and is mainly composed of a body 11, a chassis 77, a fan blade assembly, a handle 12, a decorative surface 13 and other components.

[0070] The fan blade assembly is located between the body 11 and the chassis 77, and the body 11 covers the fan blade assembly and the chassis 77. During installation, the body 11, the fan blade assembly, and the chassis 77 are completely fitted together to form a circular whole.

[0071] The center positions of the body 11 and the chassis 77 are concentric circular hollow structures, and the circular radius of the central hollow of the chassis 77 is larger than the circular radius of the central hollow on the body 11. The fan blade assembly is composed of 9 fan blades 14, and each fan blade 14 forms a closed circle after closing each other, and the center of the closed circle coincides with the center of the circular hollow of the body 11 and the chassis 77. The area of ​​the circular fan blade 14 surface formed when all the fan blades 14 on the fan blade assembly are fully closed is larger than the area of ​​the circular hollow in the center of the body 11.

[0072] When all the blades 14 of the fan blade assembly are fully opened, the center area of ​​the main body 11, the fan blade assembly and the chassis 77 is a completely hollow structure without any obstruction.

[0073] The decorative surface 13 is located on the upper surface of the annular area on the front side of the main body 11 and is arranged in a strip-shaped bead pattern that radiates in all directions.

[0074] The fan blade assembly of this embodiment is composed of 9 fan blades 14 with the same structure. When all the fan blades 14 are fully matched, they can completely cover the hollow area in the middle of the main body 11.

[0075] Each blade 14 in the blade assembly has the same shape, and the parts connected to each blade 14 are also the same. When the blade 14 is in a fully closed state, its front end points to the center of the hollow area in the middle of the shutter. Two cylindrical stop blocks 76 are set on the side of the rear end of the blade 14 facing the chassis 77 and close to the edge of the rear end surface. The center line of the two stop blocks 76 coincides with the tangent of the circle formed by the projection of the central hollow area of ​​the vertical body 11.

[0076] A fixing hole 81 is provided at the other end of the same straight line as the stop block 76. The fixing hole 81 vertically penetrates the fan blade 14 to reach the other side of the fan blade 14 away from the chassis 77. The center of the fixing hole 81 is located in the direction in which the stop block 76 moves on the moving groove 42 of the chassis 77.

[0077] The side of the fan blade 14 facing the chassis 77 is called the back side, and the side of the fan blade 14 away from the chassis 77 is called the front side.

[0078] A connecting rod 74 is arranged at the position of the fixing hole 81 on the front side of the fan blade 14, and a cylindrical protrusion arranged on the side of one end of the connecting rod 74 is completely embedded in the fixing hole 81, and the cylindrical protrusion and the connecting rod 74 are perpendicular to each other. The cylindrical protrusion passes through the entire fixing hole 81 to reach the back side of the fan blade 14. The cylindrical protrusion can rotate freely relative to the fan blade 14 in the fixing hole 81, and the connecting rod 74 can apply a force parallel to the surface of the fan blade 14 to the fan blade 14 through the cylindrical protrusion of one end of which is embedded in the fixing hole 81, thereby driving the movement of the fan blade 14.

[0079] A fixing column 75 is provided at the other end of the connecting rod 74, and the fixing column 75 is perpendicular to the connecting rod 74, and the fixing column 75 passes through both sides of the connecting rod 74. A roller 43 is provided on the fixing column 75 on the side facing the back of the blade 14. The roller 43 is sleeved on the fixing column 75, and the roller 43 can rotate freely around the fixing column 75, but will not be separated from the fixing column 75. The diameter of the end of the roller 43 facing the back of the blade 14 is larger than the diameter of the roller 43 at other positions. In order to ensure that the roller 43 does not separate from the fixing column 75, a protrusion is provided on the inner side of the end of the roller 43 close to the connecting rod 74 in the direction of the fixing column 75, and matching with the protrusion, a groove is provided around the outer side of the fixing column 75 at the position corresponding to the protrusion, and the above-mentioned protrusion is embedded in the above-mentioned groove.

[0080] The main structure of the body 11 includes a column slot 71, a positioning slot 72 and a hollow area in the middle. The column slot 71 is arranged on the inner side 73 of the body 11, and the side facing the center of the body 11 is open. The number, position and size of the column slots 71 match the fixed column 75 at one end of the connecting rod 74 of the fan assembly, and the inner diameter of the column slot 71 matches the diameter of the larger end face of the fixed column 75 facing the chassis 77. The roller 43 on the fixed column 75 can rotate freely around the fixed column 75 in the column slot 71 space.

[0081] On one side of the column groove 71 away from the fan blade assembly, a corresponding positioning groove 72 is provided on the main body 11 and is coaxial with the column groove 71. The position, number and size of the positioning groove 72 are completely matched with the position, number and size of the fixing column 75 at one end of the connecting rod 74 of the fan blade assembly, and the fixing column 75 can be completely embedded in the above-mentioned positioning groove 72.

[0082] When the fixing column 75 and the positioning groove 72 are completely installed in place, the end surface of the roller 43 with a larger diameter facing the fan blade assembly is flush with the end surface of the body 11 facing the chassis 77 .

[0083] When the body 11 rotates around the center of the body 11 , the connecting rod 74 is driven by the fixing column 75 embedded in the positioning groove 72 on the body 11 , and the fan blade 14 is driven to move through the connecting rod 74 .

[0084] The chassis 77 is mainly composed of the bottom plate 41, the moving groove 42 and the hollow area in the middle. The outer diameter of the chassis 77 is smaller than the inner diameter of the body 11. When the fan assembly, the body 11 and the chassis 77 are installed, the end surface of the roller 43 with a larger diameter facing the chassis 77 covers the outer edge of the chassis 77, which can not only hold the chassis 77, but also ensure that the roller 43 body set at one end of the connecting rod 74 of the fan assembly can roll along the outer wall of the chassis 77.

[0085] The number and position of the moving grooves 42 match the number and position of the blades 14, and the moving grooves 42 are provided with a moving track 421 along a circle of the moving grooves 42 on a side away from the blade assembly. The moving grooves 42 are long strips, and the stopper 76 located on the back of the blades 14 is embedded in the moving grooves 42. The end face width of the stopper 76 away from the back of the blades 14 is greater than the opening width of the moving grooves 42 to ensure that the stopper 76 will not be separated from the stopper. The stopper 76 can move back and forth along the moving track 421 in the moving grooves 42.

[0086] The setting direction of the movable groove 42 is such that, when viewed from the chassis 77 toward the direction of the fan blade assembly, the direction of the movable groove 42 presents a counterclockwise divergent shape. The divergent direction of the movable groove 42 coincides with the tangent of the circle formed by the projection of the central hollow area of ​​the vertical body 11. When the stop block 76 is in the initial position of the movable groove 42, all the fan blades 14 are in a fully closed state, and when the stop block 76 is completely moved to the other end of the movable groove 42, all the fan blades 14 are in a fully open state. That is, when the stop block 76 moves back and forth in the movable groove 42, all the fan blades 14 will be in the process of opening or closing.

[0087] The bottom plate 41 on the chassis 77 is located in the area between the above-mentioned moving grooves 42. Part of the bottom plate 41 is raised in the direction away from the fan assembly, that is, higher than the plane where the moving groove 42 and the lower surface of the body 11 facing the chassis 77 are located. The raised part on the bottom plate 41 is connected and fixed to the wine packaging body, and the two are fixed by bonding and fixing each other with a strong adhesive, so that the shutter device is fixed to the wine packaging body, and it can be ensured that when the body 11 is manually rotated, there will be no interference with the wine packaging body.

[0088] The handle 12 is arranged on the body 11, and the handle 12 is connected to the body 11 by a thread. An external thread is arranged at one end of the handle 12, and an internal thread is arranged inside the opening on the body 11, and the external thread and the internal thread match each other. The opening runs through the outer side of the body 11 to the inner side 73 of the body 11, and a vertical protrusion is arranged at the other end of the handle 12 for convenient left and right knob handle 12. When the handle 12 is screwed to the left, the threaded end of the handle 12 is screwed into the inner side 73 of the body 11 by matching the external thread at the other end of the handle 12 with the internal thread of the opening on the body 11. The length of the handle 12 that can be screwed into the body 11 can ensure that one end of the handle 12 can reach the side wall of the chassis 77 and can resist the chassis 77, thereby preventing the relative movement between the body 11 and the chassis 77.

[0089] When the other end of the handle 12 is twisted in the right direction, the handle 12 rotates in the opposite direction, and the threaded end of the handle 12 gradually moves away from the chassis 77, thereby releasing the mutual locking between the body 11 and the chassis 77.

[0090] The shutter device of this embodiment is opened or closed in the following manner:

[0091] When the shutter is in the fully closed state and needs to be opened, the handle 12 can be turned rightward to move the handle 12 away from the chassis 77 to release the mutual locking between the body 11 and the chassis 77. At this time, the body 11 and the chassis 77 can move freely relative to each other.

[0092] Afterwards, when the body 11 is manually screwed in the clockwise direction, the body 11 will drive the movement of the connecting rod 74 of the fan blade assembly through the fixed column 75 in the positioning groove 72. The movement of the connecting rod 74 will drive the roller 43 on the fixed column 75 in the column groove 71 of the body 11 to rotate, and the roller 43 will roll along the side wall of the chassis 77 in the direction of the body 11 being screwed. At the same time, during the movement, the connecting rod 74 will pull the fan blade 14 to move through the cylindrical protrusion at the other end of the connecting rod 74 that is completely embedded in the fixing hole 81. Since the limit block 76 fixedly connected to the fan blade 14 can only move along the moving track 421 on the moving groove 42 on the chassis 77, the moving direction of the fan blade 14 is limited to the specified direction. At this time, all the fan blades 14 move in the predetermined direction, gradually opening the middle hollow area of ​​the shutter device.

[0093] When the hollow area is fully opened, the main body 11 is rotated in the opposite direction, that is, counterclockwise, and the moving parts move in the opposite direction. At this time, all the fan blades 14 gradually return to their original state until the hollow area in the middle is completely closed.

[0094] At this time, the handle 12 is turned leftward again, and one end of the handle 12 is screwed to the outer side wall of the chassis 77 and fixedly locked.

[0095] In this embodiment, the handle 12 is set to a free state, that is, anyone in any state can twist the handle 12 to unlock the shutter, and open the shutter to check the color or other patterns of the wine inside, and then close the shutter after checking, and then tighten the handle 12 to lock it. It will not affect the normal sales of wine. Example 2
