Description

[Technical Field]

[0001] The present invention relates to a connector that assists in the movement of filler when filling a bag-shaped container such as a bean bag with filler or when moving the filler to another bag. More specifically, the present invention relates to a connector for moving filler, which comprises a connecting portion having an inner peripheral surface in the shape of a band surrounding a hollow portion formed in the center and open at both ends, a first hook portion formed along the outer peripheral surface of one open end of the connecting portion and having a rim structure, and a second hook portion formed along the outer peripheral surface of the other open end of the connecting portion, also having a rim structure and a shape symmetrical to the first hook portion, and the minimum distance between the outer peripheral surfaces of the first and second hook portions and the central axis in the direction of both ends of the hollow portion is greater than the distance between the surfaces of both ends of the first and second hook portions. [Background technology]

[0002] A bean bag, which can be used as a sofa, mat, cushion, etc., is made of a bag-shaped fabric or leather storage member filled with a granular filler material, and the filler moves within the internal space of the storage member to fit the user's body shape and support the lower part of the body.

[0003] The filling material moves to match the external shape of the body and supports the body, distributing weight evenly and improving comfort. In particular, if the filling material is made of a highly elastic foam material, the filling material deforms to match the shape of the body, distributing weight more effectively through the filling material and providing a more comfortable feel.

[0004] When a bean bag is used for a long period of time, the volume of the filling material will shrink due to permanent deformation.When this happens, the bean bag's weight distribution and cushioning performance will be reduced, making it less comfortable to use, and the filling material may need to be replaced.

[0005] Furthermore, there may be situations where the bean bag needs to be replaced due to contamination with various foreign objects or damage during use. If the bean bag has only been in use for a short period of time and the condition of the filling material is good, the cost of replacing the bean bag can be reduced and the amount of waste generated can be reduced by replacing only the bean bag's storage component.

[0006] Therefore, an opening is formed in the storage member of the bean bag for filling or separating and discharging the filler material, and Velcro (registered trademark), snap fasteners, or slide fasteners are attached to the opening to open or close the opening of the storage member.

[0007] When transferring filler material from one bean bag to another, or when separating and discharging the existing filler material from the bean bag and then filling it with new filler material, the filler material may leak out of the bean bag or temporary filler storage container into which it is being packed.

[0008] Due to the characteristics of the filler, which is manufactured using a foaming process to provide cushioning, the filler that spills out easily scatters due to the movement of surrounding air and sticks to the bottom due to static electricity, making it difficult to collect and clean the spilled filler.

[0009] In addition, since the bean bag's storage member is made of fabric or leather material that can be freely deformed to fit the user's body shape, the shape of the bean bag's opening is also easily deformed, and the filler material may leak out through the gap created by the deformed opening.

[0010] Furthermore, because bean bags that can be used as sofas, etc., are large in volume, it is difficult for one or a few people to maintain the position of the opening constant when moving the filler material from the opening of one bean bag to the opening of another bean bag that needs to be replaced or to a temporary filler storage container, etc., and if the position of the opening shifts during the process of moving the filler material, the amount of filler material that leaks out can increase even further.

[0011] In order to facilitate the storage of contents stored inside a bag-shaped storage member, which is prone to deformation, Japanese Utility Model Publication No. 46024866 (registered August 27, 1971) proposes a kitchen waste disposal funnel.

[0012] The kitchen waste disposal funnel is configured so that funnel-shaped protrusions are formed on both ends of a hollow cylinder, and kitchen waste put in through the upper funnel is collected inside the cylinder, and the lower funnel is formed with a fixing part for fixing the end of the inlet of a waste disposal bag.

[0013] However, bean bags used as sofas, etc. are much larger in volume and weight than kitchen garbage disposal bags, making it very difficult to lift the bean bag to the position of the funnel formed at the top to separate and discharge the filler.In the process of separating and discharging the filler, the shape of the opening of the bean bag becomes deformed, making it easy for the filler to spill out.

[0014] Furthermore, when the opening of a bean bag or temporary filler storage container into which the filler is to be packed is connected to the lower funnel, the opening fixedly connected to the lower funnel is likely to separate due to the external force acting due to the weight of the large amount of filler, which may result in a large amount of filler spilling out.

[0015] As another solution to prevent filler material from leaking out, U.S. Patent Publication No. 2010006177 (published on January 14, 2010) proposes a filler material movement system that is connected to the opening of the bean bag and has an aileron made of a material that can be freely deformed into any shape.

[0016] The aileron connected to the opening of the bean bag spreads out to form a connecting port that can be inserted into the inside of the opening of another bean bag or temporary filler storage container, and a fixing member such as a slide fastener is attached to the aileron so that it can be fixed onto the opening of another bean bag or temporary filler storage container.

[0017] However, in the above-mentioned filler transfer system, if the size of the aileron differs from the size of the opening of another bean bag or temporary filler storage container to which the filler is to be transferred, gaps may form when the openings on both sides are fixed with fixing members such as slide fasteners, and if the shapes or standards of the slide fasteners between the openings to be connected to each other are different, there is a problem that the openings cannot be fixed using fixing members.

[0018] As another solution to prevent the leakage of filler material, Korean Utility Model Publication No. 20-2023-0000596 (published on March 21, 2023) proposes a filling cap for bean bags that fixes the opening of the packaging container between the outer surface of a tube guide inserted into the opening of the packaging container containing the filler material and the joint between the tube holder, and has a removable cover attached to the tube holder.

[0019] A disk-shaped support portion is formed on the outer periphery of the tube holder of the filling cap for the bean bag, which catches the opening of the bean bag and prevents the filling material from leaking out when moving the filling material inside the packaging container into the inside of the bean bag.

[0020] However, in the case of the filling cap for bean bags, a method is applied in which the opening of the packaging container is clamped and fixed between the outer surface of the tube guide and the joint between the tube holder. Therefore, when transferring the filling material from a bean bag in use to another bean bag for washing, there is a problem in that if the opening of the bean bag is clamped and fixed between the outer surface of the tube guide and the joint between the tube holder, the bean bag may be damaged.

[0021] Furthermore, the connector for moving the filling material of the bean bag as described above can be sold as a standalone product, or can be a component provided as an afterthought to the bean bag, which is a sold product. However, if the connector configuration becomes complex or the volume becomes large, both the manufacturing cost and the cost of product logistics may increase.

[0022] In particular, with the rise of online commerce, the frequency of bean bags purchased from overseas online shops being shipped internationally is gradually increasing. In the case of air freight, if the volume is large compared to the product weight, a volumetric weight charge is applied, which adds shipping charges proportional to the volume. Therefore, if the volume of the connector is large, the shipping charges may increase significantly due to the components provided as ancillary parts to the product.

[0023] The increase in manufacturing costs and shipping costs of connectors, which are secondary components, is causing a decline in price competitiveness in online commerce, so there is a gradually increasing need to develop connectors that can achieve lower product prices by simplifying their structure and reducing their volume. Summary of the Invention [Problem to be solved by the invention]

[0024] The present invention aims to provide a connector structure that can prevent filler from leaking out when moving filler between bean bags or between a bean bag and a temporary filler storage container.

[0025] The present invention aims to provide a connector structure that can securely connect various types of bean bags regardless of the size and shape of the bean bag, the size and shape of the opening of the bean bag, or the type and size of the binding member applied to the opening.

[0046] Furthermore, unless otherwise defined in this specification, technical terms used in this specification should be interpreted in the sense that they are commonly understood by a person having ordinary knowledge in the technical field to which this invention belongs, and should not be interpreted in an overly comprehensive or overly narrow sense.

[0047] Furthermore, as used herein, the singular includes the plural unless the context requires otherwise.

[0048] In this application, terms such as "comprise" or "include" should not be interpreted as necessarily including all of the components or steps described in the specification, but should be interpreted as meaning that some of the components or steps may not be included, or that additional components or steps may be included.

[0049] The connector 100 for moving a filler 12 according to the present invention is connected to an opening 10 formed in a storage member 1 to assist the movement of the filler 12 when filling the bag-shaped storage member 1 with the filler 12, when discharging the filler 12 filled in the storage member 1 to the outside of the storage member 1, or when moving the filler 12 filled in the storage member 1 to another empty storage member 1.

[0050] The container (1) in which the connector (100) of the present invention is used includes various bag-shaped containers such as bean bags, bags, or bedding, and the filler (12) includes cushioning materials used in bean bags and bedding, or various raw materials used for manufacturing processed products.

[0051] The container (1) is made of a woven material or synthetic or natural leather, and is an irregular container that can be changed in shape, and can have a double layer structure with an inner and outer layer combined together, or can be made of a single layer.

[0052] Since the filler (12) moves due to its own weight, the containing member (1) in which the filler (12) is packed is positioned downward of the connector (100), with the opening (10) of the containing member (1) facing upward.

[0053] The containing member (1) from which the filler (12) is discharged is disposed above the connector (100), with the opening (10) of the containing member (1) facing downward.

[0054] (A) First embodiment of the connection between the connector (100) and the opening (10): In a first embodiment of the connection between the connector (100) and the opening (10), as shown in FIG. 1, in the case of a storage member (1) in which a binding member (11) is formed in the opening (10) itself, the opening (10) of the storage member (1) can be hooked onto the first hook portion (130) or the second hook portion (140) of the connector (100).

[0055] Thereafter, when the size of the opening (10) is reduced via the binding member (11), the opening (10) is caught by the first catch portion (130) or the second catch portion (140), and the filler (12) can be moved inside the storage member (1) while being caught between the opening (10) and the binding member (11) via the binding member (11).

[0056] (B) Second embodiment of the connection between the connector (100) and the opening (10): A second embodiment of the connection between the connector (100) and the opening (10) is applicable when a binding member (11) is formed in the opening (10) of the storage member (1) itself, and when a filler (12) stored inside an existing storage member (1) is moved into the inside of a new storage member (1).

[0057] As shown in FIG. 2, after connecting the openings (10) of the storage member (1) to the first and second hook portions (130, 140), respectively, both storage members (1) can be fixed to the first and second hook portions (130, 140), respectively, via a binding member (11).

[0058] (C) Third embodiment of the connection between the connector (100) and the opening (10): When the opening 10 of the receiving member 1 does not itself have a binding member 11 formed therein, a third embodiment of the connection between the connector 100 and the opening 10 can be applied.

[0059] As shown in FIG. 3, the opening (10) of the accommodating member (1) is passed through the hollow portion (110), which is a space formed in the center of the connector (100), and then the opening (10) is turned over and covered with the first hook portion (130) or the second hook portion (140), so that the opening (10) of the accommodating member (1) can be hooked onto the first hook portion (130) or the second hook portion (140) of the connector (100).

[0060] In order to prevent the end of the opening (10) covered by the first hook portion (130) or the second hook portion (140) from being separated, the end of the opening (10) can be fixed with a binding member (11) such as a cable tie.

[0061] According to the first to third embodiments of the connection between the connector (100) and the opening (10), by fixing the opening (10) of the containing member (1) to the connector (100), it is possible to maintain constant the shape and cross-sectional area of ​​the opening (10) of the containing member (1), which is bag-shaped and prone to deformation.

[0062] This prevents deformation of the opening (10) when filling the interior of the storage member (1) with the filler (12) or discharging the filler (12) filled in the storage member (1) to the outside of the storage member (1), and makes it easier to move the filler (12).

[0063] It should be understood that the method of fixing the opening 10 of the receiving member 1 to the connector 100 of the present invention is not limited to the methods of the first to third embodiments of the connection between the connector 100 and the opening 10, but may be a combination of these fixing methods or a different method.

[0064] The structure and shape of the connector 100 of the present invention will be described as follows.

[0065] As shown in Figures 4 and 6, the connector (100) is composed of a support part (120) having a hollow part (110) formed in the center, and first and second hook parts (130, 140) formed along the outer peripheral surface at both ends of the support part (120).

[0066] The hollow portion (110) forms a passage through which the filler (12) moves when the connector (100) is connected to the storage member (1) to move the filler (12), and the support portion (120) supports the opening (10) of the storage member (1) and prevents the filler (12) from leaking out from the widened gap between the connector (100) and the opening (10) or from decreasing the movement speed of the filler (12) due to a narrowing of the area of ​​the opening (10) caused by deformation of the storage member (1).

[0067] The first and second catch portions (130, 140) provide a catch structure that prevents separation between the connector (100) and the accommodating member (1) when the opening (10) of the accommodating member (1) is connected to the connector (100), by causing the opening (10) to catch on the first and second catch portions (130, 140).

[0068] The support part (120) is formed in a ring shape with a closed surface structure, with a band-shaped strip member surrounding the hollow part (110), forming the hollow part (110) which is an empty space inside the inner peripheral surface of the support part (120), and one end and both ends of the support part (120) are open.

[0069] Since the support portion (120) is composed of a strip member having a closed annular surface, as shown in FIG. 8, a central axis (CS) is formed in the direction of both ends of the hollow portion (110), which is an imaginary line segment connecting the centers of both open ends of the support portion (120).

[0070] A first hook portion (130) is formed along the outer peripheral surface of one end of the support portion (120) on the outer peripheral surface of the open end of the support portion (120), and the distance from the central axis (CS) of the hollow portion (110) in the direction of both ends to the outer edge of the first hook portion (130) is greater than the distance from the central axis (CS) of the hollow portion (110) in the direction of both ends to the center of the outer peripheral surface of the support portion (120), so that the first hook portion (130) forms a rim structure protruding in a direction away from the central axis (CS) of the hollow portion (110).

[0071] A second hook portion (140) is formed along the outer peripheral surface of one end of the support portion (120) on the outer peripheral surface of the other open end of the support portion (120), and the distance from the central axis (CS) of the hollow portion (110) in the direction of both ends to the outer edge of the second hook portion (140) is greater than the distance from the central axis (CS) of the hollow portion (110) in the direction of both ends to the center of the outer peripheral surface of the support portion (120), so that the second hook portion (140) forms a rim structure protruding in a direction away from the central axis (CS) of the hollow portion (110).

[0072] The first hook portion (130) and the second hook portion (140) are symmetrical to each other with respect to an imaginary plane (S4) formed by connecting the central portions of both ends of the support portion (120), and the first and second hook portions (130, 140) formed along the edges of one end and the other end of the connector (100) form a hook structure to fix the openings (10) of one or two receiving members (1).

[0073] As shown in FIG. 10b, both ends of the support part 120 are symmetrical with respect to an imaginary plane S4 formed by connecting the central parts of both ends of the support part 120.

[0074] In addition, the minimum distance that the protruding ends of the rims formed by the first and second hooking portions (130, 140) are spaced from the central axis (CS) in the direction of both ends of the hollow portion (110) is greater than the distance that the open ends of the first and second hooking portions (130, 140) are spaced along the central axis (CS) in the direction of both ends of the hollow portion (110), i.e., the length of an imaginary line segment connecting the centers of both open ends of the support portion (120).

[0075] The ratio of the minimum distance that the rim formed by such first and second hook portions (130, 140) protrudes from the central axis (CS) of the hollow portion (110) to the length of both open ends of the first and second hook portions (130, 140) reduces the length of the movement path of the filler (12) inside the connector (100) and can prevent an increase in the volume of the connector (100).

[0076] By reducing the length of the open ends between the first and second hook portions (130, 140) of the connector (100), when the opening portion (10) of the containing member (1) is connected and fixed to the first and second hook portions (130, 140), the opening portion (10) of the containing member (1) can be prevented from moving along the surface of the outer circumferential surface of the support portion (120), thereby improving the convenience of the work of moving the filler (12).

[0077] Furthermore, the connector (100) according to the present invention can be sold as a standalone product, or can be a component provided as a secondary component to a product containing a container (1) such as a bean bag. However, as the volume of the connector (100) increases, both the manufacturing cost and the logistics cost of the product increase.

[0078] In particular, the popularity of online commerce has led to a gradual increase in the frequency of international deliveries, and in the case of intercontinental international deliveries where delivery by cargo vehicle is not possible, air transport is becoming the primary method of choice rather than sea transport, which takes longer to deliver.

[0079] In the case of air transport, since the loading space inside the plane is limited, if the volume is large compared to the weight of the product, a volumetric weight method is applied, which adds shipping charges in proportion to the volume. However, if the volume of the connector (100) is large, the shipping charges will increase significantly due to the connector (100) provided as an accessory to the product, which can cause price competitiveness issues in online commerce that requires international delivery.

[0080] Therefore, it is preferable to manufacture the connector 100 from synthetic resin materials, including plastic, to reduce the cost and weight of the product.

[0081] (1) First embodiment of connector (100): As shown in Figures 4, 6 and 16, the cross-sectional shape of the support part (120) of the connector (100) cut along an imaginary plane (S4) formed by connecting the central parts of both ends of the support part (120) may be circular or regular polygonal.

[0082] If the cross section of the support part (120) is in the form of a regular polygon, there is a possibility that the filler (12) will leak out from the widened gap between the opening (10) of the accommodating member (1) and the outer peripheral surface of the support part (120) during the process of the filler (12) moving through the connector (100), and therefore it is preferable to form a large number of surfaces on the support part (120) to adopt a cross section shape that is close to a circle.

[0083] When the opening (10) of the receiving member (1) is connected to the connector (100), a binding member (11) is used to maintain the size of the opening (10) constant and to prevent the receiving member (1) from being separated from the first hook portion (130) or the second hook portion (140).

[0084] The binding member (11) may be made of a material including various strings or cable ties, or may be made of a slide fastener formed in the opening (10) itself, and the size of the opening (10) is made smaller than the size of the rim formed by the first hook portion (130) or the second hook portion (140).

[0085] This keeps the opening (10) in close contact with the outer peripheral surface of the support part (120), preventing the filler (12) from leaking out through the widened gap between the connector (100) and the opening (10).

[0086] However, when the connector (100) having the circular or regular polygonal cross-sectional shape of the support portion (120) according to the first embodiment is connected and fixed via a slide fastener formed in the opening (10) itself to move the filler (12), the slide fastener moves due to an external force applied to the connector (100) by the weight of the containing member (1) and the filler (12), and as shown in Figure 13, the size of the widened gap between the connector (100) and the opening may increase, and the filler (12) may leak out through the widened gap.

[0087] (2) Second embodiment of connector (100): As shown in Figures 5, 7 and 9, the connector (100) of the second embodiment is configured so that a first bending portion (101) and a second bending portion (102) are connected together, and the first bending portion (101) and the second bending portion (102) are symmetrical to each other with respect to a virtual plane (S1) passing through a central axis (CS) in the direction of both ends of the hollow portion (110).

[0088] The outer and inner surfaces of the support portion (120) of the first bending portion (101) and the first and second hook portions (130, 140) are bent to form a convex shape toward the outside of the hollow portion (110), and the outer and inner surfaces of the support portion (120) and the first and second hook portions (130, 140) of the second bending portion (102) are bent to form a convex shape toward the outside of the hollow portion (110).

[0089] The longitudinal ends of the first and second bending portions (101, 102) are connected to each other on an imaginary plane (S1), and the first and second bending portions (101, 102) form one connector (100) member.

[0090] The distances of the protruding rim ends of the support parts (120) of the first and second bending parts (101, 102) and the first and second hooking parts (130, 140) from the central axis (CS) vary depending on the positions along the length of the first and second bending parts (101, 102).

[0091] The distance from the central axis (CS) is maximum at the connecting portion between the first and second bending portions (101, 102) formed on the imaginary plane (S1) and is minimum at the center portions of the first and second bending portions (101, 102), and the distance between both ends of the connecting portion between the first and second bending portions (101, 102) is greater than the distance between the center portions of the first and second bending portions (101, 102).

[0092] Therefore, the cross-sectional shape of the support part (120) of the connector (100) cut along an imaginary plane (S4) formed by connecting the central parts of both ends of the support part (120) can be in the form of two parabolic ends connected symmetrically to each other, or an elliptical or arch-shaped form in which the ends of two polygonal line segments are connected symmetrically to each other, as shown in Figures 16 and 17.

[0093] The end face shape of the connector (100) as in the second embodiment is such that when the storage member (1) is fixed to the first hook portion (130) or the second hook portion (140) via the slide fastener attached to the opening (10), the connection portion between the first and second bending portions (101, 102) faces the slide fastener (140).

[0094] This narrows the angle at which the containing members (1) on both sides of the opening (10) open apart from each other in the area where the connector (100) is inserted and not closed by the slide fastener, reduces the size of the gap between the connector (100) and the opening (10) caused by external forces applied to the connector (100), and reduces the amount of filler (12) that leaks out during the process of the filler (12) moving.

[0095] In this case, when the cross-sectional shape of each support portion (120) of the first and second bending portions (101, 102) according to the second embodiment is formed in such a manner that the ends of two arcs are connected to be symmetrical with respect to the virtual plane (S1), the central angle of each arc formed by the support portions (120) of the first and second bending portions (101, 102) can be formed within a range of 100° to 150°.

[0096] In addition, when the cross section of the support part (120) constituting the first and second bending parts (101, 102) is formed in a shape in which the ends of two polygonal line segments forming an arch shape are connected to be symmetrical with each other, it is preferable to apply an end face shape that is close to the shape in which the ends of two parabolas are connected to be symmetrical with each other by forming a large number of faces formed on the support part (120) in order to minimize the outflow of the filler (12) to the outside.

[0097] In particular, when the cross-sectional shape of the support part (120) is formed in a form in which the ends of two parabolas are connected symmetrically to each other, or in a form in which the ends of two polygonal lines forming an arch shape are connected symmetrically to each other, the joint between the outer surfaces of the support parts (120) of the first and second bending parts (101, 102) forms a wedge shape.

[0098] One or both ends of the wedge of the joint between the outer surfaces of the support part (120) face the slide fastener applied to the opening (10), and when the opening (10) is closed using the slide fastener, the wedge shape of the joint between the outer surfaces of the support part (120) reduces the angle of expansion between the receiving members (1) on both sides at the portion of the opening (10) that is not closed by inserting the connector (100), thereby minimizing the size of the gap formed between the connector (100) and the opening (10) compared to other cross-sectional shapes of the support part (120).

[0099] More preferably, the central angle of each arc formed by the support portions (120) of the first and second bending portions (101, 102) can be formed within the range of 130° to 135°, and such an angle can appropriately maintain the movement speed of the filler (12) according to the cross-sectional area of ​​the hollow portion (110) of the connector (100), while at the same time reducing the amount of filler (12) that leaks out from the gap at the connection portion between the opening (10) of the accommodating member (1) and the connector (100).

[0100] If the central angle of the arc formed by the support portions (120) of the first and second bending portions (101, 102) is less than 100°, the distance between the central portions of the inner surfaces of the support portions (120) will become narrower, the cross-sectional area of ​​the hollow portion (110) will decrease, and the amount of movement of the filler (12) moving through the internal space of the hollow portion (110) will become excessively small, which may reduce the convenience of using the connector (100).

[0101] If the central angle of the arc formed by the support portions (120) of the first and second bending portions (101, 102) exceeds 150°, the angle at which the containing members (1) on both sides of the opening (10) spread apart in the area not closed by the slide fastener can increase, and as the containing members (1) spread apart, an external force is applied, which may cause the slide fastener to retract, resulting in the filling material (12) leaking out from the widened gap between the connector (100) and the opening (10).

[0102] In addition, when the cross-sectional shape of each support portion (120) of the first and second bending portions (101, 102) according to the second embodiment is elliptical, the ratio DL:DS of the distance DL between the rim ends of the first and second hooking portions (130, 140) at the connecting portion between the first and second bending portions (101, 102) and DS between the rim ends of the first and second hooking portions (130, 140) at the center positions of the first and second bending portions (101, 102) may be within a range of 1:0.4 to 1:0.8.

[0103] The ratio of the distance Ds between the rim ends of the first and second hooking parts (130, 140) at the center of each of the first and second bending parts (101, 102) can be applied not only to the case where the cross-sectional shape of each support part (120) of the first and second bending parts (101, 102) is elliptical, but also to the cross-sectional shape where the ends of two parabolas are connected symmetrically to each other, or the cross-sectional shape where the ends of two polygonal line segments forming an arch are connected symmetrically to each other.

[0104] More preferably, the ratio of DL to DS can be formed within the range of 1:0.60 to 1:0.70, and such a ratio can appropriately maintain the movement speed of the filler (12) according to the cross-sectional area of ​​the hollow portion (110) of the connector (100), while at the same time reducing the amount of filler (12) that leaks out from the gap at the connection between the opening (10) of the accommodating member (1) and the connector.

[0105] If the ratio of DL to DS is less than 1:0.4, the distance between the central portions of the inner surfaces of the support portion (120) will be narrower, the cross-sectional area of ​​the hollow portion (110) will be reduced, and the movement of the filler (12) will be reduced, which may result in a decrease in the convenience of using the connector (100).

[0106] If the ratio of DL to Ds exceeds 1:0.8, the angle at which the containing members (1) on both sides of the opening (10) expand from each other in the area not closed by the slide fastener increases, which may result in an increase in the amount of filler material leaking through the expanded gap between the connector (100) and the opening (10).

[0107] (3) Third embodiment of connector (100): When using the connector 100 to move a large amount of filler material 12, such as when filling a large storage member 1 with filler material 12 or discharging filler material 12 from the storage member 1, the weight of the storage member 1 and the filler material 12 acts as an external force, which may cause deformation of the connector 100.

[0108] In particular, since the connector (100) is manufactured from synthetic resin material to reduce unit cost and weight, it is prone to torsional deformation due to external forces acting on parts of the connector (100). When torsional deformation of the connector (100) occurs, the filler (12) may leak out or the connector (100) may be damaged.

[0109] Therefore, the connector (100) according to the third embodiment can be applied to both the connector (100) according to the first embodiment or the connector (100) according to the second embodiment, and provides a reinforcing structure that increases the rigidity of the connector (100).

[0110] A first deformation prevention rib (131) may be formed on the outer edge of one end of the first catch portion (130), protruding at a certain height in a direction away from the support portion (120) along the longitudinal direction of the central axis (CS) toward both ends of the hollow portion (110).

[0111] A second deformation prevention rib (141) may be formed on the outer edge of the other end of the second catch portion (140), protruding at a certain height in a direction away from the support portion (120) along the longitudinal direction of the central axis (CS) of the hollow portion (110) in the direction of both ends.

[0112] The first and second deformation prevention ribs (131, 141) are symmetrical to each other with respect to an imaginary plane (S4) formed by connecting the central portions of both ends of the support portion (120) of the connector (100).

[0113] (4) Fourth embodiment of connector (100): The connector (100) of the fourth embodiment can be applied to both the connector (100) of the first embodiment and the connector (100) of the second embodiment, and provides a fixing structure that can stably connect the opening (10) of the accommodating member (1) via the first and second hook portions (130, 140).

[0114] As shown in FIG. 10a, the inner surfaces of the opposing rims of the first and second hooking portions (130, 140) are inclined at a certain angle to each other.

[0115] When an imaginary plane tangent to the inner surfaces of the opposing rims of the first hooking portion (130) or the second hooking portion (140) is defined as plane S2, and an imaginary plane tangent to the center point of the outer peripheral surface of the support portion (120) is defined as plane S3, it is preferable that the angle of the inner portion where each plane (S2, S3) intersects is formed within the range of 90° to 140°.

[0116] The connector (100) is manufactured by injection molding using a mold, and the opposing inner surfaces of the first and second hooking portions (130, 140) and the outer peripheral surface of the support portion (120) are formed by the mold, which is separated in a direction away from the central axis (CS) after the injection molding is completed.

[0117] In this case, if the angle of the inner part where each plane (S2, S3) intersects is less than 90°, when the mold is separated after injection molding, the first and second catch portions (130, 140) may catch on the inner surfaces of the opposing rims. If the catch between the mold and the inner surfaces of the rims of the first and second catch portions (130, 140) is avoided by methods such as splitting the mold, this may result in an increase in the mold manufacturing cost, which may increase the unit manufacturing cost of the connector (100).

[0118] Furthermore, when the user connects the connector (100) to the opening (10) of the containing member (1) and then moves the filler (12), in order to prevent the containing member (1) from being separated from the connector (100), it is necessary to fix the size of the opening (10) via the binding member (11).

[0119] Since the fastening of the binding member (11) is performed manually by the user, there must be sufficient free space between the rims of the first and second hooking portions (130, 140) for the user's fingers to enter. However, if the angle of the inner portion where each plane (S2, S3) intersects is less than 90°, the separation distance between the rims of the first and second hooking portions (130, 140) will decrease, reducing the free space required for fastening the binding member (11), which may reduce the convenience of the user in using the connector (100).

[0120] When the openings (10) of the two storage members (1) are connected to the open ends of the connector (100) respectively and the filler (12) is moved, the weight of the storage member (1) arranged downward increases as the filler (12) is packed into it, or an external force applied by the user to the storage member (1) or the connector (100) may act in a direction that separates the openings (10) of the connector (100) and the storage member (1) from each other.

[0121] If the angle of the inner part where each plane (S2, S3) intersects exceeds 140°, the inner inclined surface of the first catch portion (130) or the second catch portion (140) will form a gentle angle, and the catch action of the opening (10) of the receiving member (1) through the first and second catch portions (130, 140) may not be performed properly. When an external force acts in a direction that separates the connector (100) and the opening (10) of the receiving member (1), the receiving member (1) may easily separate from the connector (100), which may significantly reduce the convenience of the user in using the connector (100).

[0122] In addition, the connecting portion between the inner peripheral surface of the support portion (120) and the outer surfaces of the first and second hook portions (130, 140) has a chamfered cross-sectional shape to form a gently curved surface, and the chamfered cross-sectional shape of the curved surface of the connecting portion between the support portion (120) and the first and second hook portions (130, 140) prevents damage to the connecting portion between the support portion (120) and the first and second hook portions (130, 140) due to stress concentration when an external force acts on the connector (100).

[0123] The rims of the first and second hook portions (130, 140) may be configured to have a certain thickness, and thus an external inclined surface may be formed on the outer surface of the rims of the first and second hook portions (130, 140) corresponding to the inclination of the internal inclined surface formed on the inner surface of the rims of the first and second hook portions (130, 140).

[0124] The external inclined surfaces formed on the outer surfaces of the rims of the first and second hooking portions (130, 140) are shaped so that the distance between the outer surfaces of the rims of the first and second hooking portions (130, 140) decreases as the distance approaches the center axis (CS) from the end of the protruding rim of the first and second hooking portions (130, 140), and the connecting portion between the outer peripheral surface of the support portion (120) and the inner surfaces of the first and second hooking portions (130, 140) also has a chamfered cross-sectional shape to form a gently curved surface.

[0125] The external inclined surfaces formed on the rims of the first and second hook portions (130, 140) allow the filler (12) caught on the outer surfaces of the first and second hook portions (130, 140) to move along the inclined surfaces and pass through the openings (10) when the openings (10) of the two receiving members (1) are connected to the open ends of the connector (100) respectively, thereby minimizing the amount of residual filler (12) remaining inside the receiving members (1) and improving the convenience of the user in using the connector (100).

[0126] (5) Fifth embodiment of connector (100): The connector (100) of the fifth embodiment can be applied to both the connector (100) of the first embodiment and the connector (100) of the second embodiment, and provides an ideal shape and standard of the first and second hooking portions (130, 140) that can simultaneously reduce the volume and weight of the connector (100) and ensure the hooking performance of the opening (10) of the accommodating member (1) via the first and second hooking portions (130, 140).

[0127] When the filler (12) is moved through the connector (100), a groove formed by the outer peripheral surface of the support portion (120) and the rims of the first and second hook portions (130, 140) is formed along the periphery of the side surface of the connector (100) depending on the arrangement direction of the connector (100).

[0128] When the distance between the ends of the rims of the first and second hooking portions (130, 140) is defined as the width of the groove, and the shortest distance from the center of the outer surface of the support portion (120) to the imaginary line segment connecting the ends of the rims of the first and second hooking portions (130, 140) is defined as the depth of the groove, it is preferable that the ratio of the width of the groove formed by the outer surface of the support portion (120) and the rims of the first and second hooking portions (130, 140) to the depth of the groove is formed within a range of 1:0.7 to 1:4.

[0129] If the ratio of the groove depth to the groove width is less than 1:0.7, the spacing between the rims of the first and second hook portions (130, 140) will decrease, reducing the free space required for fastening the binding member (11), which may reduce the user's convenience in using the connector (100).

[0130] Furthermore, if the ratio of the depth of the groove to the width of the groove exceeds 1:4, the volume of the connector (100) increases in the process of ensuring the minimum size of the first and second catch portions (130, 140) to prevent separation between the connector (100) and the opening (10) of the accommodating member (1), which may result in an increase in the manufacturing cost of the connector (100) and the shipping cost at the logistics stage.

[0131] In this case, the minimum depth of the groove is 10 mm, and by ensuring the minimum depth of the groove, when the openings (10) of the two accommodating members (1) are respectively connected to the open ends of the connector (100) and the filler (12) is moved, the connector (100) and the openings (10) of the accommodating members (1) can be prevented from being separated from each other.

[0132] (6) Best embodiment of connector (100): The optimal embodiment of the connector (100) ensures the amount of movement of the filler material (12) through the internal space of the hollow portion (110) while providing a range of specifications for the connector (100) to prevent increases in manufacturing costs and logistics costs due to an increase in the volume of the connector (100).

[0133] According to the second embodiment, the cross-sectional shape of the first and second bending portions (101, 102) is such that the two arcs formed by each support portion (120) are connected to each other symmetrically with respect to the plane (S1), and it is preferable that the central angle of each arc is within the range of 130° to 134°.

[0134] The distance DL between the rim ends of the first and second hooking portions (130, 140) at the connecting portion between the first and second bending portions (101, 102) is within the range of 250mm to 270mm, and the distance DS between the rim ends of the first and second hooking portions (130, 140) at the center positions of the first and second bending portions (101, 102) is within the range of 180mm to 200mm.

[0135] The width of the groove, which is the distance between the ends of the rims of the first and second hooking portions (130, 140), is formed in the range of 50 mm to 70 mm, and the depth of the groove, which is the shortest distance from the center of the outer surface of the support portion (120) to the imaginary line connecting the ends of the rims of the first and second hooking portions (130, 140), is formed in the range of 20 mm to 40 mm.

[0136] The method of moving the filler 12 using the connector 100 according to the first to fifth embodiments or the best embodiment configured as described above is as follows.

[0137] In the process of transferring the filler (12) packed in the storage member (1) to another storage member (1) with an open interior by the second embodiment of the connection between the connector (100) and the opening (10), particularly when the binding member (11) made of a slide fastener is formed on the opening (10) of each storage member (1), the transfer of the filler (12) is carried out in the following steps.

[0138] In the first step, the connector (100) is placed adjacent to the opening (10) of the first housing member (1).

[0139] In the second stage, the second hooking portion (140) of the connector (100) is inserted into the opening (10) so that the end of the opening (10) of the first housing member (1) is positioned between the first and second hooking portions (130, 140), and then the binding member (11) consisting of a slide fastener is closed to make the open area of ​​the opening (10) narrower than the cross-sectional area formed by the end of the side of the rim of the second hooking portion (140), thereby fixing the opening (10) on the second hooking portion (140).

[0140] In the third step, the first catch portion (130) of the connector (100) is placed close to the opening of the second housing member (1).

[0141] In the fourth step, the first hooking portion (130) of the connector (100) is inserted into the opening (10) so that the end of the opening (10) of the second accommodating member (1) is positioned between the first and second hooking portions (130, 140), and then the binding member (11) consisting of a slide fastener is closed to make the open area of ​​the opening (10) narrower than the cross-sectional area formed by the end of the side of the rim of the first hooking portion (130), thereby fixing the opening (10) on the first hooking portion (130).

[0142] In the fifth stage, the container member (1) filled with the filler material (12) and the container member (1) with an empty interior are turned upside down, and the container member (1) with an empty interior is turned upside down, and the filler material (12) moves toward the container member (1) with an empty interior due to its own weight.

[0143] Once the transfer of the filler (1) is complete, in the sixth step, the openings (10) of each storage member (1) are separated from the connector (100). In order to prevent the filler (12) newly packed into the storage member (1) from leaking out, the openings (10) of the storage member (1) newly packed with the filler (12) must be kept facing upward during the process of separating the connector (100).

[0144] When the separation of the connector (100) from the opening (10) of the storage member (1) newly filled with the filler (12) is completed, the slide fastener formed on the opening (10) of the storage member (1) newly filled with the filler (12) is closed to completely close the opening (10), thereby completing the transfer of the filler (12).

[0145] In this case, the first and second storage members (1) correspond to either an empty storage member (1) into which the filler (12) is to be filled or a storage member (1) from which the filler (12) is to be separated and discharged.

[0146] In addition, another method of moving the filler (12) using the connector (100) according to the first to fifth embodiments or the best embodiment can be performed as follows, and another type of method of moving the filler (12) is a method in which the first and third embodiments of the connection between the connector (100) and the opening (10) are combined.

[0147] In particular, it can be used in the process of transferring a filler (12) packed in a second storage member (1) that does not include a binding member (11) formed on the opening (10) itself to a first storage member (1) that has a binding member (11) made of a slide fastener formed thereon and is in an empty state inside, or conversely, it can be used in the process of transferring a filler (2) packed in a first storage member (1) that has a binding member (11) made of a slide fastener formed thereon to a second storage member (1) that does not include a binding member (1) formed on the opening (10) itself and is in an empty state inside.

[0148] In the first step, the connector (100) is placed adjacent to the opening (10) of the second housing member (1).

[0149] In the second stage, as shown in FIG. 3, the end of the opening (10) of the second accommodating member (1) is passed into the hollow portion (110) from the side where the first catch portion (130) is formed, and then the part of the second accommodating member (1) on the end side of the opening (10) that has passed through the hollow portion (110) is turned over to cover the outer surface of the connector (100).

[0150] In the third stage, the second accommodating member (1) is separated from the opening (10) and a separately formed binding member (11) is attached around the outer circumferential surface of the support portion (120) of the connector (100), and the outer circumferential surface of the support portion (120) and the portion of the second accommodating member (1) covering the connector (100) are tightly fixed to each other by the binding member (11).

[0151] In this case, the binding member (11) of the second housing member (1) may be any one selected from a cable tie, a string, or a binder, and may also be any other type of member having a similar function.

[0152] In the fourth step, the second hook portion (140) of the connector (100) is inserted into the opening (10) of the first storage member (1), which has an empty interior and is the target for filling with the filler (12), so that the end of the opening (10) is positioned between the first and second hook portions (130, 140).

[0153] Thereafter, the binding member (11) consisting of a slide fastener is closed, and the opening area of ​​the opening (10) is narrower than the cross-sectional area formed by the end of the side surface of the rim of the second hooking portion (140), thereby fixing the opening (10) onto the second hooking portion (140).

[0154] In the fifth stage, the second housing member (1) and the first housing member (1) are turned upside down so that they are positioned vertically, and the filler (12) moves from the second housing member (1) into the inside of the first housing member (1) due to its own weight. When the movement of the filler (1) is completed, the sixth step is carried out, in which the openings (10) of the respective containing members (1) are separated from the connectors (100).

[0155] At this time, if the storage member (1) newly packed with the filler (12) is the first storage member (1), the binding member (11) of the first storage member (1) is closed to completely close the opening (10) of the first storage member (1), and if the storage member (1) newly packed with the filler (12) is the second storage member (1), the opening (10) of the second storage member (1) is closed via another binding member (11), thereby preventing the filler (12) from leaking out.

[0156] Although the embodiments of the present invention have been described with reference to the above, it will be understood by those skilled in the art to which the present invention pertains that the present invention may be embodied in other specific forms without changing the technical spirit or essential characteristics thereof.

[0157] Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not limiting. The scope of the present invention described in the above detailed description is indicated by the claims that follow, and all modifications and variations derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
