DETAILED DESCRIPTION
[0016] The present invention will be further described below in conjunction with specific embodiments: Example 1
[0017] like Figure 1-12 As shown, a flexible packaging container comprises a container body 1, a lower cover 2 connected to the container body 1, and an upper cover 3 covering the lower cover 2. In the prior art, a threaded container outlet 5 is formed on the upper end of the container body 1, the lower cover 2 is screwed and sleeved outside the container outlet 5, and the upper cover 3 covers the lower cover 2 to seal the container outlet 5. The container body 1, the lower cover 2, and the upper cover 3 are also made of different materials, so there are many parts to produce, the process and time are increased, and the production cost is also increased.
[0018] In the present application, the upper end of the container body 1 is integrally formed with the lower cover 2, and the lower end of the container body 1 is open. The lower end of the container body 1 is sealed after the material is injected into the container body 1, thereby reducing the overall components, and the production and assembly processes are also reduced accordingly, and the production cost and time are also effectively reduced; a container outlet 5 is formed on the lower cover 2, and the container outlet 5 is offset at the top of the lower cover 2; a rotating covering structure 4 is provided between the upper cover 3 and the lower cover 2, and a protrusion 31 corresponding to the container outlet 5 is offset at the bottom of the upper cover 3, and the rotating covering structure 4 is rotated to the corresponding position so that the protrusion 31 is correspondingly inserted into the container outlet 5; a detachable sealing member 6 is provided in the container outlet 5, and the protrusion 31 is inserted into the container outlet 5 so that the sealing member 6 is detached from the container outlet 5.
[0019] When transporting or not in use, the protrusion 31 and the container outlet 5 are staggered by rotating the rotating cover structure 4, so as to avoid the sealing member 6 being accidentally opened, and it is not easy to cause the material in the container body 1 to flow out or change its nature after opening; when in use, the protrusion 31 is rotated to the corresponding position by the rotating cover structure 4, so that the protrusion 31 can be inserted into the container outlet 5, so that the sealing member 6 falls off, and the container can be used normally, which can greatly improve the sealing safety of the container outlet 5. Example 2
[0020] The difference from Example 1 is that the rotating covering structure 4 includes a ring 41 movably connected to the lower cover 2, a guide block 42 formed at the bottom of the ring 41 and an arc-shaped guide groove 43 formed at the top of the lower cover 2 and arranged around the center, the inner surface of the outer periphery of the ring 41 is formed with a clamping ring 411, and the upper outer periphery of the lower cover 2 is formed with a clamping groove 21 clamped and connected to the clamping ring 411, the upper cover 3 is hingedly or otherwise connected to the ring 41, so that the upper cover 3 rotates with the rotation of the ring 41, and the guide block 42 moves in the arc-shaped guide groove 43, so that the upper cover 3 can rotate relative to the lower cover 2, that is, the relative position of the protrusion 31 and the container outlet 5 can be controlled, so as to achieve the effect of staggered installation or plug-in connection of the protrusion 31 and the container outlet 5. Example 3
[0021] The difference from Example 2 is that: generally, the two ends of the arc guide groove 43 do not overlap, the arc guide groove 43 is formed in an arc shape with a notch on the top of the lower cover 2, and positioning grooves 431 are formed at both ends of the arc guide groove 43. The positioning groove 431 is composed of the end of the arc guide groove 43 and the oblique convex strip 432 formed in the arc guide groove 43. The guide block 42 can be respectively clamped in the positioning groove 431 to play a certain positioning and fixing role.
[0022] When the guide block 42 of the ring 41 rotates to the end of the arc-shaped guide groove 43, the guide block 42 stops rotating and is prevented from rotating after breaking through the oblique convex strip 432. Only when reverse rotation is applied, the guide block 42 disengages from the oblique convex strip 432 of the positioning groove 431 and continues to rotate in the reverse direction to the positioning groove 431 at the other end. Example 4
[0023] The difference from Example 3 is that the rotation angle of the protrusion 31 is the same as the angle formed by the two ends of the arc guide groove 43, and the positioning groove 431 at one end is on the same radius straight line as the protrusion 31 or the container outlet 5, so that when the protrusion 31 rotates to the positioning groove 431 at one end, it can be accurately inserted into the container outlet 5. Example 5
[0024] The difference from Examples 1-4 is that a groove 7 is offsetly formed on the top of the lower cover 2 and is on the same radius as the container outlet 5. The rotating cover structure 4 is rotated to a corresponding position so that the protrusion 31 is correspondingly inserted into the groove 7. The groove 7 is not connected to the inside of the container body 1. The groove 7 is used to accommodate and position the protrusion 31 in the groove 7 when the protrusion 31 is installed in a staggered manner with the container outlet 5. Example 6
[0025] The difference from Example 5 is that a pair of fixing grooves 8 are formed on the top of the lower cover 2, and an insertion strip 32 is formed on the bottom of the upper cover 3 to be plugged and fixed with any of the fixing grooves 8, the insertion strip 32 and the protrusion 31 are on the same radial straight line, and the pair of fixing grooves 8 correspond to the container outlet 5 and the groove 7 on the same radial straight line respectively.
[0026] The insertion of the insert strip 32 into the fixing groove 8 can further fix the positions of the upper cover 3 and the lower cover 2, so that the upper cover 3 can be fixed at different positions during transportation or when not in use and after use, thereby improving the sealing safety of the container outlet 5. Example 7
[0027] The difference from Example 6 is: Fig. 9 As shown, more preferably, the angle between the container outlet 5 and the groove 7 and the center of the lower cover 2 is 180 degrees, the two ends of the arc guide groove 43 and the positioning groove 431 are respectively located on the radius straight line of the container outlet 5 and the groove 7, and the pair of fixing grooves 8 are also respectively located on the radius straight line of the container outlet 5 and the groove 7. Example 8
[0028] The difference from Example 1 is that the sealing member 6 is a plastic block torn downward from the container outlet 5, and the protrusion 31 is formed with a long ridge 311 for piercing the sealing member 6. When in use, the upper cover 3 is covered on the lower cover 2, and the protrusion 31 is inserted into the container outlet 5. The long ridge 311 presses the plastic block downward to tear it downward and open it. Example 9
[0029] The difference from Example 1 is: Fig.13 As shown, the sealing member 6 is a plastic block torn upward from the container outlet 5, and a vertical connecting rod 61 and a horizontal pressure rod 62 are formed on the plastic block. The cantilever end of the horizontal pressure rod 62 extends out of the edge of the container outlet 5, and the protrusion 31 is formed with a pressing portion for pressing the horizontal pressure rod 62 to extend out of the edge of the container outlet 5. When in use, the pressing portion of the protrusion 31 presses the portion of the horizontal pressure rod 62 extending outside the edge of the container outlet 5, and the plastic block is tilted upward through the vertical connecting rod 61 to open.
[0030] Working principle: When transporting or not in use, the upper cover 3 is rotated to the corresponding position, that is, the guide block 42 of the ring 41 moves in the arc guide groove 43 and stops after reaching one end of the arc guide groove 43. The guide block 42 is clamped in the positioning groove 431, and the protrusion 31 of the upper cover 3 is staggered and covered with the container outlet 5. The protrusion 31 is inserted into the groove 7 of the lower cover 2. At this time, the insertion strip 32 of the upper cover 3 can be inserted into the fixing groove 8 at the corresponding position, so that the relative position of the upper cover 3 and the lower cover 2 is stably fixed.
[0031] When in use, after the upper cover 3 is opened, the upper cover 3 is rotated to the corresponding position, that is, the guide block 42 of the ring 41 moves to the other end in the arc guide groove 43 and then stops, the guide block 42 is clamped in the positioning groove 431, and the protrusion 31 of the upper cover 3 is inserted and installed with the container outlet 5. The protrusion 31 can pierce the sealing member 6 of the container outlet 5, so that the material in the container body 1 can flow out. At this time, the insertion strip 32 of the upper cover 3 can be inserted in another position fixing groove 8, so that the relative position of the upper cover 3 and the lower cover 2 is stably fixed.
