[0034] A first embodiment of the present invention will be described below with reference to the drawings, and the first embodiment relates to a bulk container.

[0035] The bulk container includes a box 1, a liner bag 2, and a support member. A discharge port 111 is provided on a side 11 below the box 1, and a discharge valve 33 is provided within the discharge port 111. A flange 4 is connected to the liner bag 2, and the flange 4 is operably connected to and communicates with the discharge valve 33. After the flange 4 is connected to the discharge valve 33, a gap 5a is formed between the liner bag 2 and the side 11 at the discharge port 111. A support member is provided in the gap 5a, and a portion of the support member may be located within the gap 5a. The portion of the support member located within the gap 5a supports the liner bag 2 and prevents damage to the liner bag 2.

[0036] In actual manufacturing processes, as shown in FIGS. 1 to 7, a liner bag 2 is typically placed in a box 1, with a drain port 111 provided on the lower side of the box 1 and a drain valve 3 installed within the drain port 111. To facilitate the smooth drainage of liquid from the liner bag 2, as shown in FIGS. 1 to 3, the liner bag 2 typically has a liner bag body 11a, whose flange 4 communicates with the drain valve 3, allowing the liquid within the liner bag 2 to be easily drained. The inventors discovered that the reason the liner bag 2 is so fragile is that after the flange 4 is connected to the drain valve 3, it becomes separated by a certain distance from the side wall 13 of the box 1. Therefore, during transportation of the liner bag 2 containing liquid, the liner bag 2 shakes, repeatedly impacting the joint between the flange 4 and the liner bag body 11a, causing the joint to rupture and resulting in liquid leakage.

[0037] In order to solve the problems found by the inventors, as shown in Figs. 1 to 4, the liner bag 2 has a liner bag body 11a, and the liner bag body 11a is provided with a liquid discharge port.

[0038] The support member is a reinforcing sheet 4a attached to the outer surface of the liner bag body 11a, and the reinforcing sheet 4a has an opening that communicates with the liquid discharge port. A flange 4 is fixedly connected to the reinforcing sheet 4a, and the flange 4 has a through-hole that communicates with the opening and the liquid discharge port.

[0039] Since the reinforcing sheet 4a is provided on the liner bag body 11a, this reinforcing sheet 4a can strengthen the joint between the liner bag body 11a and the flange 4, thereby increasing the toughness of the joint between the liner bag body 11a and the flange 4 and reducing the risk of leakage from the liner bag 2.

[0040] Specifically, the reinforcing sheet 4a is generally formed using a tough, high-strength film, and in some embodiments, as shown in FIG. 6, the reinforcing sheet 4a may be a rubber sheet, a silica gel sheet, or a plastic sheet.

[0041] Specifically, in the actual process, the reinforcing sheet 4a may be attached to the liner bag body 11a first, and the opening of the reinforcing sheet 4a may be connected to the liquid outlet of the liner bag body 11a, and then the flange 4 may be welded to the reinforcing sheet 4a and the liner bag body 11a by heat fusion welding. As shown in Figures 1 and 2, the flange 4 is pressed against the reinforcing sheet 4a.

[0042] Of course, in some embodiments, as shown in Figures 8 to 10, the reinforcing sheet 4a may be an airbag-type reinforcing sheet 4a. As shown in Figure 8, the reinforcing sheet 4a is a flat airbag located between the flange 4 and the liner bag main body 11a, which not only reinforces the strength of the joint between the flange 4 and the liner bag main body 11a, but also supports the liner bag main body 11a and prevents the liner bag main body 11a from shaking violently.

[0043] Of course, if the reinforcing sheet 4a is in the form of a film, it can also play a role in supporting the liner bag 2, but the effect is far less than that of an airbag-type reinforcing sheet 4a.

[0044] In some embodiments, the reinforcing sheet 4a may be a reinforcing sheet made of a profiled foam material, for example, using a foam material such as EPP or EVA.

[0045] After the liner bag 2 is placed in the box body 1, the reinforcing sheet 4a can be overlapped on the side wall 13 of the box body 1, so that the reinforcing sheet 4a has support points and further strengthens the support force of the reinforcing sheet 4a.

[0046] 6 and 9, the flange 4 includes a disk body 121a and a connecting tube 122a. The disk body 121a is attached to the reinforcing sheet 4a and fixedly connected to the reinforcing sheet 4a. The disk body 121a and the reinforcing sheet 4a may be connected by thermal welding, or, of course, the disk body 121a may be bonded to the reinforcing sheet 4a with an adhesive. The connecting tube 122a is fixedly connected to the disk body 121a coaxially, and after the disk body 121a and the connecting tube 122a are connected, a through hole is formed inside the disk body 121a and the connecting tube 122a. In order to enable the connecting tube 122a to be connected to an external device (e.g., the discharge valve 3), a connecting ring 321a that can be connected to an external product is provided on the outer surface of the connecting tube 122a. In this embodiment, the connecting ring 321a is a snap ring, but the snap ring can connect the connecting tube 122a and the discharge valve 3, and in some embodiments, the connecting ring 321a may be a screw.

[0047] It should be noted that the shape of the liner bag 2 may vary. For example, the liner bag 2 may have a square shape as shown in FIG. 1, or of course, the liner bag 2 may have a polygonal shape as shown in FIG. 2. The shape of the liner bag 2 may be arbitrarily changed as needed.

[0048] The liner bag body 11a is provided with a filling port 112a, through which a liquid can be injected into the liner bag body 11a.

[0049] As shown in Figures 5 to 7 and 9 to 10, a discharge port 111 is provided on the side of the lower part of the box body 1, and a discharge valve 3 is provided inside this discharge port 111. The flange 4 of the liner bag 2 is connected to the discharge valve 3 and communicates with it.

[0050] Since the reinforcing sheet 4a is provided on the liner bag body 11a, this reinforcing sheet 4a can strengthen the joint between the liner bag body 11a and the flange 4, thereby increasing the toughness of the joint between the liner bag body 11a and the flange 4 and reducing the risk of leakage from the liner bag 2.

[0051] Specifically, the connection portions of the flange 4 and the liner bag main body 11a are spaced apart from the side wall 13 of the box body 1, and the reinforcing sheet 4a is superimposed on the side wall 13, so that the reinforcing sheet 4a not only serves to reinforce the liner bag main body 11a, but can also support the liner bag main body 11a.

[0052] 6 and 10, a groove 23a is provided in the bottom surface of the box 1, with the discharge valve 3 positioned on the groove wall of the groove 23a and the flange 4 positioned within the groove 23a. Preferably, as shown in FIG. 5, the groove 23a is provided in the bottom surface of the box 1 at a position close to the side wall 13 of the box 1 so that the distance between the flange 4 and the side wall 13 is not too great.

[0053] As shown in FIG. 6, after the flange 4 is connected to the discharge valve 3, the reinforcing sheet 4a is large and overlaps the side wall 13, so that the reinforcing sheet 4a can provide support to the liner bag body 11a and reduce the risk of the liner bag body 11a being torn.

[0054] When the reinforcing sheet 4a is an airbag-type reinforcing sheet 4a, the airbag-type reinforcing sheet 4a is filled in the gap 5a between the liner body 11a and the side wall 13, thereby achieving the highest support effect. As shown in FIG. 10, after the reinforcing sheet 4a is filled in the gap 5a between the liner body 11a and the side wall 13, the airbag-type reinforcing sheet 4a and the profiled foam-type reinforcing sheet 4a are compressed and bent to form an arc surface 41a that contacts the liner body 11a.

[0055] 10 , the discharge valve 3 includes a valve element 31a and a connecting seat 32a. The valve element 31a is installed in the discharge port 111. The connecting seat 32a is fixed within the valve element 31a. The connecting seat 32a is coaxially installed on the flange 4. The connecting seat 32a includes a connecting ring 321a and a baffle plate 322a. The connecting ring 321a is detachably connected to the flange 4. Specifically, the connecting ring 321a is detachably connected to the connecting tube 122a of the flange 4, for example, by a screw connection or a snap connection. The baffle plate 322a is installed perpendicular to the connecting ring 321a and parallel to the disk body 121a of the flange 4. An airbag-type reinforcing sheet 4a is placed between the baffle plate 322a and the disk body 121a, and when the liner bag main body 11a is pressed against the airbag-type reinforcing sheet 4a, the baffle plate 322a can play a role in supporting the reinforcing sheet 4a, and by preventing the reinforcing sheet 4a from collapsing, the reinforcing sheet 4a can play a role in supporting the bag main body 11a.

[0056] 6 and 10, the bottom of the groove 23a and the bottom plate of the box 1 are connected by inclined surfaces 231a, and each inclined surface 231a is inclined from bottom to top in a direction away from the discharge port 111. That is, the groove wall of the groove 23a is the inclined surface 231a, and since the groove wall of the groove 23a is the inclined surface 231a, the inclined surface 231a plays a role in supporting the liner bag main body 11a and prevents damage to the liner bag main body 11a.

[0057] The present invention also includes a second embodiment, which is substantially similar to the first embodiment. The bulk container according to this embodiment also includes a box body 1 and a liner bag 2. A discharge port 111 is provided on the lower side 11 of the box body 1, and a discharge valve 3 is provided within the discharge port 111. A flange 4 is connected to the liner bag 2; specifically, the liner bag 2 is provided with a discharge port, and the periphery of the discharge port is welded to the flange 4, thereby connecting the liner bag 2 and the flange 4. After the flange 4 is connected to the discharge valve 3, the liquid in the liner bag 2 can be discharged through the discharge valve 3.

[0058] 12 and 13, after the flange 4 is connected to the discharge valve 3, a gap remains between the periphery of the portion where the liner bag 2 and flange 4 are connected and the side portion 11 of the box body 1, and if liquid is present in the liner bag 2, the liner bag 2 is prone to tearing due to the collision of the liquid, resulting in damage to the liner bag 2. Furthermore, the flange 4 in conventional bulk containers is prone to tearing, and according to research by the inventors, it was found that the reason the flange 4 is prone to tearing is because the liner bag 2 pulls on the flange 4 as it swings, causing cracks in the welded portion of the flange 4, which causes liquid leakage from the bulk container.

[0059] Unlike the first embodiment, the support member in this embodiment is a support block 5, at least a portion of which is located above the flange 4, and the support block 5 is capable of filling the gap between the liner bag 2 and the side portion 11. The liner bag 2 is supported by the support block 5 so that it does not shake violently inside the box, thereby preventing the liner bag 2 from breaking.

[0060] Preferably, the upper surface of the portion of the support block 5 located above the flange 4 is an inclined surface, and the inclined surface supports the liner bag 2 by inclining from top to bottom toward the center of the bulk container.

[0061] Specifically, the support block 5 is sandwiched outside the flange 4 and is attached to the side 11 of the box body 1 where the discharge outlet 111 is provided, and the support block 5 can fill the gap between the liner bag 2 and the side 11. Because the support block 5 can fill the gap between the liner bag 2 and the side 11 of the box body 1, the liner bag 2 can abut against the support block 5, and the support block 5 supports the liner bag 2, which prevents the liner bag 2 from being torn and damaged, and reduces the probability of the liner bag 2 being damaged.

[0062] 14 to 16, a locking groove 51 is provided on the underside of the support block 5, penetrating the support block 5 along the axial direction of the flange 4, and at least a portion of the flange 4 toward the side portion 11 is located within the locking groove 51. Of course, in some embodiments, the locking grooves 51 may be provided on the left and right sides of the support block 5. As shown in FIG. 16, the groove bottom of the locking groove 51 is arc-shaped, the openings of the locking grooves 51 are arranged parallel to each other, and the flange 4 is circular. Therefore, when the groove bottom of the locking groove 51 is arc-shaped, it is easy to hook the support block 5 onto the outside of the flange 4, specifically, the outside of the connecting tube of the flange 4.

[0063] As shown in Figures 15 and 16, the upper surface of the support block 5 is an inclined surface 52 that slopes downward from the side 11 toward the center of the bulk container, so that the liner bag 2 can be moved to the side 11 of the box body 1 (i.e., the side wall 13 of the box body 1) by the inclined surface 52.

[0064] On the other hand, as shown in Figures 15 and 16, a storage groove 53 is also provided on the end face toward one end of the side portion 11 of the support block 5, and the part of the discharge valve 3 exposed to the outside of the side portion 11 is stored in this storage groove 53, thereby making it possible to bring the support block 5 and the front of the side portion 11 into closer contact with each other.

[0065] 17, the box 1 includes a base 12 and a side wall 13 attached to the base 12. A groove 121 is provided in the base 12 so that the liquid in the liner bag 2 can be drained as quickly as possible, and the drain port 111 is located in the groove wall of the groove 121. As the groove 121 is positioned at the lowest point, the liquid in the liner bag 2 can be completely drained.

[0066] Of course, it should be noted that in some embodiments, the outlet 111 may also be located in the side wall 13 .

[0067] 17 to 22, the box 1 further includes a support seat 6 located in the recessed groove 121, and is installed facing the flange 4 along the axial direction of the flange 4. A guide groove 61 is provided on the support seat 6 on the side facing the flange 4, and the guide groove 61 connects the flange 4 to the upper surface of the base 12. This makes it easy for the liquid in the liner bag 2 to flow into the flange 4 and the discharge valve 3 via the guide groove 61.

[0068] As shown in Figures 15 and 20, the shape of the bottom of the support seat 6 is adapted to the shape of the groove 121, and the bottom surface of the support seat 6 is a first inclined surface 65, and accordingly, the groove 121 is also provided with a second inclined surface 1211 corresponding to this first inclined surface 65.

[0069] 19, in order to facilitate the introduction of liquid into the flange 4, the guide groove 61 is an arc-shaped recessed groove 121, which is a fan-shaped groove that gradually widens from the flange 4 toward the upper surface of the base 12. It is also preferable that the upper surface of the support seat 6 is flush with the upper surface of the groove.

[0070] 19, in order to facilitate engagement between the support seat 6 and the support block 5, first engagement grooves 54 are provided on both end faces of the support block 5 in the width direction, and both ends of the support seat 6 in the width direction are engaged in the two first engagement grooves 54. Specifically, as shown in FIG. 16, a first engagement groove 54 is provided on the lower part of the side surface of the support block 5, one end of the support seat 6 in the width direction is engaged in the first engagement groove 54, and the upper surface of the support seat 6 and the groove bottom of the first engagement groove 54 in the height direction of the support seat 6 abut against each other.

[0071] As shown in FIG. 19, a second engagement groove 62 is provided at one end of the support seat 6 facing the support block 5, and one end of the support block 5 facing the support seat 6 is engaged within this second engagement groove 62.

[0072] In some embodiments, as shown in FIG. 23, the support block 5 and the support seat 6 are fixedly connected to each other, so that the support block 5 and the support seat 6 are unlikely to be lost when the box 1 is collected.

[0073] 24 and 25, in some embodiments, since the box 1 can be folded, to facilitate collection of the support seat 6 and the support block 5, the inner sides of both widthwise ends of the support seat 6 are positioned outside the widthwise ends of the support block 5, and the inner sides of both widthwise ends of the support seat 6 and the outer sides of both widthwise ends of the support block 5 are hinged to each other, as shown in FIGS. 24 and 25. At the same time, a storage groove 63 is provided at the bottom of the support seat 6, and the support block 5 can be inverted relative to the support seat 6 until it is stored in the storage groove 63.

[0074] 24 and 25, a first hinge hole is provided on the outer side of both ends of the support block 5 in the width direction, and a second hinge hole 64 is provided on the inner side of both ends of the support seat 6 in the width direction. At the same time, the bulk container is provided with two hinge shafts, which are inserted into the corresponding first hinge hole and second hinge hole 64, respectively, thereby enabling the support block 5 and the support seat 6 to be hingedly connected to each other.

[0075] The material of the support block 5 is preferably an elastic material such as rubber, EVA, EPP, etc. At the same time, the material of the support seat 6 is also preferably an elastic material such as rubber, EVA, EPP, etc.

[0076] It should be noted that this embodiment may further include the above-mentioned reinforcing sheet 4a, that is, the reinforcing sheet 4a and the support block 5 exist simultaneously.

[0077] The present invention provides a third embodiment of a bulk container, and as shown in Figures 26 to 29, the bulk container of this embodiment is substantially structurally identical to the bulk container of the second embodiment, with the main difference being that the support block 5 of this application is not structurally identical to the support block 5 of the first embodiment, and this embodiment does not include a support seat 66.

[0078] In particular, it is preferable to make the inclined surface 52 of the support block 5 an arcuate surface in order to make it easier for the support block 5 to support the liner bag 2, thereby allowing the inclined surface 52 to slope more smoothly and preventing damage to the liner bag 2.

[0079] Preferably, in this embodiment, as shown in Figures 26 to 31, the support block 5 is removably fixed to the flange 4, so that in the actual installation process, the support block 5 can first be fixed to the flange 4, and then the flange 4 can be fixed to the discharge valve 3 inside the box body 1, which makes it easy to install and fix the support block 5.

[0080] Specifically, to facilitate connection between the support block 5 and the flange 4, as shown in Figures 30 to 32, the support block 5 is provided with an engagement portion 55 that penetrates the support block 5 along the thickness direction of the support block 5 and opens toward the side of the support block 5 to form an opening 56. The flange 4 is engaged into the engagement portion 55 through this opening 56, and the axial direction of the flange 4 extends along the thickness direction of the support seat 6; that is, the axial direction of the flange 4 is approximately parallel to the thickness direction of the support block 5. By adopting this method, the support block 5 can be sandwiched outside the flange 4.

[0081] Preferably, as shown in FIG. 32 , each of the side walls 13 defining the opening 56 of the support block 5 is provided with a guide portion 57 that guides the flange 4 into the restricting opening 58 and engages with it. Specifically, the guide portion 57 is a single inclined guide surface 52. As shown in FIG. 32 , the inclined guide surface 52 includes an outer inclined surface 57152 and an inner inclined surface 57252. The outer inclined surface 57152 extends from the outside of the opening 56 toward the center of the opening 56 toward the inside of the engagement portion 55, and the inner inclined surface 57252 extends from the outside of the opening 56 toward the inside of the engagement portion 55 in a direction away from the center of the opening 56. At the same time, the outer inclined surface 57152 is located outside the inner inclined surface 57252, and the outer inclined surface 57152 and the inner inclined surface 57252 are connected to each other. The addition of the inclined guide surface 52 makes it easier for the flange 4 to engage with the engagement portion 55 of the support block 5.

[0082] Furthermore, since the support block 5 is preferably made of a flexible and elastic material, when assembling the flange 4 and the support block 5, the guide portion and the flange 4 come into contact, and as the assembly continues, the guide portion deforms and spreads outward, at which time the flange 4 enters the engagement portion 55 until the flange 4 and the flange 55 are properly fitted together.

[0083] 31 to 33, the engagement portion 55 is a single circular hole, and it is preferable that a transition fit or clearance fit is applied between the flange 4 and this circular hole. Of course, an interface fit may also be used between the flange 4 and the circular hole.

[0084] The support block 5 and support seat 6 according to this embodiment and the first embodiment described above may be supported by a plastic material, and may of course also be manufactured from other materials such as wood, silicone, or rubber.

[0085] 27 and 31, to strengthen the discharge valve 3, the discharge valve 3 is generally provided with a limiting plate 31 located on the side of the discharge valve 3 facing the flange 4. A part of this limiting plate 31 protrudes toward the discharge valve 3 to form a protrusion 311, and a storage groove 53312 is formed on the side facing the discharge valve 3, and the valve control switch 32 of the discharge valve 3 is located in this storage groove 53312. Preferably, the support block 5 has a limiting opening 58 on the side facing the limiting plate 31, and the protrusion 311 is located within this limiting opening 58. The inter-fitting restriction between the protrusion 311 and the limiting opening 58 can prevent the support block 5 from rotating relative to the flange 4, and further prevent damage to the liner bag 2 due to relative shaking between the support block 5 and the flange 4 during transportation of the liner bag 2.

[0086] The limiting opening 58 and the open opening 56 are preferably provided facing each other on both sides of the support block 5 along a direction perpendicular to the thickness direction of the support block 5. The limiting opening 58 is an elongated recessed groove 121, and the shape of the protruding portion 311 and the shape of the limiting opening 58 fit together, and the limiting opening 58 extends in the direction from the open opening 56 toward the limiting opening 58, so that when the support block 5 engages with the outside of the flange 4, the limiting opening 58 also engages within the protruding portion 311.

[0087] A fourth embodiment of the present invention further provides a method for manufacturing a liner bag. Specifically, the liner bag may be manufactured by first attaching a reinforcing sheet, which is the reinforcing sheet of the above-described embodiment, to a liner bag body, so that an opening is provided in the reinforcing sheet. At the same time, the liner bag body is also the liner bag body of the above-described embodiment, and the liner bag body is provided with a liquid discharge port, and the opening in the reinforcing sheet is connected to the liquid discharge port of the liner bag body. It is preferable that the opening in the reinforcing sheet is provided coaxially with the liquid discharge port of the liner bag body.

[0088] The flange of the above embodiment is then heat-welded to the reinforcing sheet, and a through hole is provided in the flange. The through hole in the flange, the opening in the reinforcing sheet, and the liquid outlet in the liner bag body are connected, so that the liquid inside the liner bag can be discharged.

[0089] When the reinforcing sheet is a sheet-like reinforcing sheet, i.e., a thin sheet such as a rubber sheet, a silica gel sheet, or a plastic sheet, when the flange is heat-fused to the reinforcing sheet, the reinforcing sheet and the liner bag body are simultaneously heat-fused, thereby reducing the number of welding steps.

[0090] Furthermore, when the reinforcing sheet is an airbag-type reinforcing sheet, the liner bag body and the airbag-type reinforcing sheet may be heat-welded first, and then the flange and the airbag-type reinforcing sheet may be heat-welded, but of course the above welding steps may be interchanged.

[0091] While preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to provide additional embodiments using aspects, features, and concepts of various patents, applications, and publications.

[0092] These and other changes can be made to the embodiments in light of the above detailed description. In general, in the claims, the terms used should not be considered limited to the specific embodiments disclosed in the description and claims, but should be understood to include all possible embodiments along with all equivalents to which these claims are entitled.

[0093] Those skilled in the art will understand that the above embodiments are specific examples for implementing the present invention, and that in actual applications, various changes in form and details are possible without departing from the spirit and scope of the present invention.
