Technical Field

[0001] This utility model belongs to the field of ton bag technology, and specifically relates to a ton bag. Background Technology

[0002] BOOM (Bulk Unit) bags are flexible transport packaging containers with advantages such as moisture resistance, dust resistance, radiation protection, and robust safety, and they possess sufficient structural strength. BOOM bags are a type of unitized container, used with cranes or forklifts to achieve unitized transport, suitable for transporting large quantities of bulk, granular, or powdery materials. BOOM bags are widely used for transporting powdery, granular, and lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals. Currently, existing BOOM bags typically involve lifting the bag and cutting open the bottom for unloading, which damages the bag, prevents reuse, and causes environmental pollution due to their single-use nature.

[0003] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a ton bag.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this utility model is to provide a ton bag that can solve the problem of waste of ton bag resources caused by unloading from the bottom of existing ton bags.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows: A ton bag includes: a bag body and a discharge valve mechanism.

[0007] A discharge port is cut into the bottom wall of the bag. The discharge valve mechanism is installed at the discharge port and includes: a fixed base, a locking ring, multiple support rods, a slide barrel, a slide rod, and a moving rod. A fixed ring is fixed to the bottom of the fixed base and inserted into the discharge port. The locking ring is fixed to one end of the fixed ring located at the outer end of the bag. Multiple support rods are fixed to the fixed base and have fixed heads at their top ends. The slide barrel slides within the fixed ring. A threaded hole is cut into the top wall of the fixed head. The top end of the slide rod is fixed to the top wall of the threaded hole. The moving rod slides on the slide rod and has a threaded head that matches the threaded hole at its top end. A fixed frame is fixed to the inner side wall of the bottom end of the slide barrel. The moving rod slides on the fixed frame and has a knob head fixed to one end of the fixed frame at its bottom.

[0008] In one embodiment of this utility model, multiple pairs of longitudinal reinforcing strips are fixed on the outer side wall of the bag body to improve the longitudinal toughness of the bag body side wall and play a reinforcing role.

[0009] In one embodiment of this utility model, a pair of transverse reinforcing strips are fixed on the outer wall of the discharge port to improve the transverse toughness of the bag sidewall and to strengthen it.

[0010] In one embodiment of this utility model, each pair of longitudinal reinforcing strips is fixed with a handle at the top, and multiple handles are used to lift the bag.

[0011] In one embodiment of this utility model, multiple bolts are fixed at equal intervals at the bottom of the fixing seat.

[0012] In one embodiment of this invention, a limiting ring is fixed to one end of the slide barrel at the bottom of the fixing ring. The limiting ring serves to limit the highest position of the slide barrel as it slides upward.

[0013] In one embodiment of this utility model, limiting grooves are chiseled on the inner sidewalls of the multiple support rods, and multiple limiting blocks are fixed to the top of the outer sidewall of the slide barrel. The multiple limiting blocks slide within the multiple limiting grooves respectively. By having the multiple limiting blocks slide within the multiple limiting grooves, the slide barrel is prevented from rotating, and the lowest position of the slide barrel is limited, preventing the slide barrel from slipping off the fixing ring.

[0014] In one embodiment of this utility model, a conical head is fixed to the top of the fixing head, and a limiting groove is used to prevent material from accumulating at the top of the fixing head.

[0015] In one embodiment of this utility model, the movable rod is provided with a sliding groove, and a limiting head is fixed at one end of the sliding rod located within the sliding groove. The limiting head slides within the sliding groove to prevent the movable rod from slipping off the sliding rod.

[0016] In one embodiment of this utility model, a spring is installed inside the slide groove, between the limiting head and the bottom wall of the slide groove. When the spring is compressed, its elastic force is used to push the moving rod downward.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0022] like Figures 1 to 6 As shown, a ton bag according to one embodiment of the present invention includes: a bag body 1 and a discharge valve mechanism 2.

[0023] like Figures 1 to 6 As shown, a discharge port 101 is cut into the bottom wall of the bag body 1. A discharge valve mechanism 2 is installed at the discharge port 101. The discharge valve mechanism 2 includes: a fixed base 201, a locking ring 203, multiple support rods 206, a sliding barrel 208, a sliding rod 213, and a moving rod 214. A fixing ring 202 is fixed to the bottom of the fixed base 201 and inserted into the discharge port 101. The locking ring 203 is fixed to one end of the fixing ring 202 located at the outer end of the bag body 1. Multiple support rods 206 are all fixed to the fixed base 201, and a fixing head 207 is fixed to their top ends. The slide barrel 208 slides within the fixed ring 202. A threaded hole 212 is drilled on the top wall of the fixed head 207. The top end of the slide rod 213 is fixed to the top wall of the threaded hole 212. The moving rod 214 slides on the slide rod 213. A threaded head 217 that matches the threaded hole 212 is fixed at the top end of the moving rod 214. A fixed frame 219 is fixed on the inner side wall of the bottom end of the slide barrel 208. The moving rod 214 slides on the fixed frame 219. A knob head 218 is fixed at one end of the fixed frame 219 at the bottom.

[0024] When the bag 1 is filled with material, the slide barrel 208 slides up until its top end is against the bottom wall of the fixed head 207, sealing the gaps between the multiple support rods 206. Simultaneously, the threaded head 217 at the top of the moving rod 214 is screwed into the threaded hole 212, and the knob head 218 at the bottom of the moving rod 214 abuts against the bottom of the fixed frame 219, thus fixing the slide barrel 208 in place. Additionally, the fixed seat 201 is secured to the bottom of the fixed ring 202 by a locking ring 203, thus being installed at the discharge port 101.

[0025] When unloading is required, the knob head 218 drives the moving rod 214 to rotate, causing the threaded head 217 to be turned out of the threaded hole 212. Then, the sliding drum 208 is pulled downwards. As the sliding drum 208 moves downwards, the moving rod 214 slides downwards on the sliding rod 213 via the fixing bracket 219 and the knob head 218. The sliding drum 208 slides downwards until its top surface is flush with the top surface of the fixing seat 201. Then, the material inside the bag 1 flows into the sliding drum 208 through the gaps between the multiple support rods 206, and is then discharged downwards through the sliding drum 208.

[0026] like Figures 1 to 6 As shown, multiple pairs of longitudinal reinforcing straps 102 are fixed to the outer wall of the bag body 1 to improve the longitudinal toughness of the side wall of the bag body 1, thus providing reinforcement. A pair of transverse reinforcing straps 103 are fixed to the outer wall of the discharge port 101 to improve the transverse toughness of the side wall of the bag body 1, thus providing reinforcement. Each pair of longitudinal reinforcing straps 102 has a handle 104 fixed to its top, and multiple handles 104 are used to lift the bag body 1.

[0027] like Figures 1 to 6As shown, multiple bolts 204 are evenly spaced at the bottom of the fixing base 201. Multiple pairs of bolt holes 205, matching the bolts 204, are drilled on the bottom wall of the bag body 1 and the locking ring 203. Nuts are threaded onto the bottom of each bolt 204. By inserting multiple pairs of bolts 204 into the multiple pairs of bolt holes 205 and threading nuts onto the bottom of the locking ring 203, the fixing base 201 and the locking ring 203 are locked at the discharge port 101.

[0028] like Figures 1 to 6 As shown, a limiting ring 209 is fixed to one end of the slide barrel 208 at the bottom of the fixing ring 202. The limiting ring 209 is used to limit the highest position of the slide barrel 208 when sliding upward. Limiting grooves 211 are carved on the inner side walls of multiple support rods 206, and multiple limiting blocks 210 are fixed to the top of the outer side wall of the slide barrel 208. The multiple limiting blocks 210 slide in the multiple limiting grooves 211 respectively. By having the multiple limiting blocks 210 slide in the multiple limiting grooves 211 respectively, the slide barrel 208 is prevented from rotating on the one hand, and the lowest position of the slide barrel 208 when sliding downward is limited on the other hand, preventing the slide barrel 208 from slipping off the fixing ring 202.

[0029] like Figures 1 to 6 As shown, a conical head 221 is fixed to the top of the fixed head 207, and a limiting groove 211 is used to prevent material from accumulating at the top of the fixed head 207. A sliding groove 215 is provided inside the moving rod 214, and a limiting head 216 is fixed to one end of the sliding rod 213 located within the sliding groove 215. The limiting head 216 slides within the sliding groove 215 to prevent the moving rod 214 from slipping off the sliding rod 213. A spring 220 is installed inside the sliding groove 215, between the limiting head 216 and the bottom wall of the sliding groove 215. When the spring 220 is compressed, its elastic force is used to push the moving rod 214 downwards.

[0030] Working principle: When the bag 1 is filled with material, the slide barrel 208 slides up to its top and fits against the bottom wall of the fixed head 207, sealing the gap between the multiple support rods 206. At the same time, the threaded head 217 at the top of the moving rod 214 is screwed into the threaded hole 212, and the knob head 218 at the bottom of the moving rod 214 abuts against the bottom of the fixed frame 219, thereby fixing the slide barrel 208 in place by the moving rod 214.

[0031] When unloading is required, the moving rod 214 is rotated by the knob head 218, which pulls the threaded head 217 out of the threaded hole 212. Then, the spring force of the spring 220 pushes the moving rod 214 downward, and then pulls the slide barrel 208 downward. When the slide barrel 208 slides downward until the multiple limit blocks 210 slide to the bottom of the multiple limit grooves 211, the slide barrel 208 can move to a position where its top surface is flush with the top surface of the fixed seat 201. Then, the material in the bag body 1 can flow into the slide barrel 208 through the gap between the multiple support rods 206, and then be discharged downward through the slide barrel 208.

[0032] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
