Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Fig. 1-2 show that the utility model discloses a soft packing bag flap with good sealing performance, including body 1 and the lid 2 that have the mouth of pipe. The cover body 2 covers the pipe orifice and is in threaded connection with the pipe body 1. The threaded connection between the tube 1 and the cap 2 is common in the prior art. The nozzles include a first nozzle 11 and a second nozzle 12 of an inverted conical shape. The first pipe orifice 11 and the second pipe orifice 12 are both of a structure with a large upper opening and a small lower opening. The second nozzle 12 is located below the first nozzle 11 and communicates with the first nozzle 11. The first pipe orifice 11 and the second pipe orifice 12 are positioned on the same central axis, the diameter of the mouth part of the second pipe orifice 12 is smaller than the diameter of the bottom part of the first pipe orifice 11, and the first pipe orifice 11 and the second pipe orifice 12 are mutually jointed to form a pipe orifice. The first pipe orifice 11 is internally provided with a first sealing plug 4 which is matched with the inner wall of the first pipe orifice 11. The second pipe orifice 12 is internally provided with a second sealing plug 5 which is matched with the inner wall of the second pipe orifice 12. The first sealing plug 4 and the second sealing plug 5 are also in the shape of an inverted cone, and when the first sealing plug 4 moves downwards, the first sealing plug is tightly connected with the inner wall of the first pipe orifice 11 in a conical surface sealing mode, and when the second sealing plug 5 moves downwards, the second sealing plug is tightly connected with the inner wall of the second pipe orifice 12 in a conical surface sealing mode. A pull wire 6 and a spring 61 are connected between the first sealing plug 4 and the second sealing plug 5. The pull wire 6 and the spring 61 are fixed at both ends to the first sealing plug 4 and the second sealing plug 5, respectively. The first sealing plug 4 has a cavity 41 formed therein. A stop 7 is movably arranged in the cavity 41. The stopper 7 is provided with a connecting rod 71. The upper end of the connecting rod 71 movably penetrates through the first sealing plug 4 and is connected with the cover body 2. The concrete structure is that a through hole communicated with the cavity 41 is processed on the top surface of the first sealing plug 4, the connecting rod 71 can move through the through hole, and the stop 7 cannot pass through the through hole and is limited in the cavity 41. Install on the lid 2 and support tight piece 8, support tight piece 8 and the top surface of first sealing plug 4 inconsistent when lid 2 is screwed up with 1 screw thread of body, can oppress first sealing plug 4 and move down simultaneously. Specifically, the cover 2 includes an inner top wall 21 facing the nozzle, and the upper end of the connecting rod 71 is connected to the inner top wall of the cover 2. The abutting block 8 is fixed on the inner top wall of the cover body 2.
In the specific design, the inclination angle of the inner wall of the first nozzle 11 is the same as or different from the inclination angle of the inner wall of the second nozzle 12, so that the tightness degree of the first sealing plug 4 fitted in the first nozzle 11 and the tightness degree of the second sealing plug 5 fitted in the second nozzle 12 can have different sealing effects. In addition, in order to improve the sealing effect, one or more annular grooves are processed on the outer circumferential surfaces of the first sealing plug 4 and the second sealing plug 5, and the sealing ring 3 is installed in the annular grooves. The sealing ring 3 is a sealing part commonly used in the prior art.
Wherein, a fluid channel 13 is arranged in the tube body 2 below the second nozzle 12, the fluid channel 13 is communicated with the second nozzle 12, and the canned materials can flow into the packaging bag through the fluid channel 13.
When the pipe orifice is closed, the cover body 2 is arranged above the pipe orifice, the first sealing plug 4 and the second sealing plug 5 are both positioned in the pipe orifice, the cover body 2 is screwed, when the cover body 2 moves downwards through threaded connection, the first sealing plug 4 and the second sealing plug 5 move downwards along with the downward movement and respectively contact the inner walls of the first pipe orifice 11 and the second pipe orifice 12, the cover body 2 continues to move downwards, the abutting block 8 starts to contact the first sealing plug 4 and generate downward pressure, and the abutting block 8 forces the first sealing plug 4 to continue to move downwards until being tightly matched with the first pipe orifice 11. At the same time, the second sealing plug 5 moves downwards under the spring force of the spring 61 until it is tightly fitted to the second nozzle 12. When the nozzle needs to be opened, according to the operation reverse movement, the cover body 2 moves upwards to drive the stop block 7 to move upwards, the stop block 7 is in contact with the inner wall of the cavity 41 and forces the first sealing plug 4 to move upwards, and the second sealing plug 5 also moves upwards through the traction of the traction rope 6 while the first sealing plug 4 moves upwards, so that the nozzle can be opened.
The mode that the present embodiment seals through first mouth of pipe 11 and the conical surface of first sealing plug 4 and the mode that the conical surface of second mouth of pipe 12 and second sealing plug 5 is sealed, can effectively seal the mouth of pipe, and the leakproofness is good, effectively prevents the material in the soft packaging bag and leaks. In addition, through the cooperation of haulage rope 6, dog 7 and connecting rod 71 use, when opening lid 2, can pull out first sealing plug 4 and second sealing plug 5 in step, make things convenient for orificial opening, labour saving and time saving, the practicality is strong.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
