Description

Connector for moving charging material and method for moving charging material using the same

[0001] The present invention relates to a connector that assists the movement of a filler when filling the inside of a bag-shaped receiving member such as a bean bag or moving the filler to another bag, and more particularly, to a connector for moving a filler, the connector comprising: a connecting portion having a ring-shaped belt shape surrounding a hollow portion formed in a central portion of an inner circumference and having both ends open; a first engaging portion formed along an outer circumference of the open end of the connecting portion and forming a rim structure; and a second engaging portion formed along an outer circumference of the open other end of the connecting portion and forming a rim structure and having a shape symmetrical to the first engaging portion, wherein the outer circumferences of the first and second engaging portions are formed such that a minimum distance from a central axis in the direction of both ends of the hollow portion is greater than a distance between the surfaces of both ends of the first and second engaging portions.

[0002] Bean bags, which are used as sofas, mats, or cushions, are made of a pouch-shaped fabric or leather material filled with a filling material in the form of granules. The filling material moves within the space of the filling material to fit the shape of the user's body and supports the lower part of the body.

[0003] Since the filler moves to support the body in a state where it conforms to the external shape of the body, the weight is evenly distributed, which improves the feeling of use. In particular, when the filler is composed of a highly elastic foam material, the filler deforms to conform to the shape of the body, and the weight is distributed more effectively by the filler, providing a more comfortable feeling of use.

[0004] If a bean bag is used for a long time, the volume of the filling material will decrease due to permanent deformation. When the volume of the filling material decreases, the weight distribution and cushioning performance of the bean bag will decrease, resulting in a decrease in usability, and therefore, the filling material may need to be replaced.

[0005] In addition, there may be situations where the bean bag needs to be replaced due to contamination by various foreign substances during use or damage to the bean bag, and if the bean bag has a short period of use and the filling material is in good condition, 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 receiving material.

[0006] Accordingly, an opening is formed in the receiving member of the bean bag for filling or discharging the filling material, and a Velcro, snap fastener, or slide fastener is mounted in the opening to open or close the opening of the receiving member.

[0007] When transferring the filling material inside a bean bag to the inside of another bean bag or when removing the existing filling material from the bean bag and filling it with new filling material, the filling material may leak out from the bean bag being filled or from the temporary filling storage container.

[0008] Due to the nature of the filling material manufactured through a foaming process to provide cushioning, the filling material that leaks out is easily scattered by the movement of the surrounding air, and sticks to the floor surface due to the attraction created by static electricity, making it difficult to collect or clean the leaked filling material.

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

[0010] In addition, since bean bags that can be used as sofas, etc., are large in volume, when one or a small number of people move the filling material from the opening of the bean bag to the opening of another bean bag that is to be replaced or to a temporary filling storage container, it is difficult to maintain the position of the opening at a constant level, and there is a problem that the amount of filling material leaking may increase further if the opening position is misaligned during the filling material movement.

[0011] In order to facilitate the storage of contents stored inside a pocket-shaped storage member that can easily change shape, Japanese Utility Model Publication No. 46024866 (registered on August 27, 1971) proposes a funnel for disposing kitchen waste.

[0012] The above kitchen waste disposal funnel is configured to have funnel-shaped protrusions formed at both ends of a hollow cylinder to collect kitchen waste disposed of through the upper funnel into the cylinder, and to have a fixing portion formed at the lower funnel to fix the inlet end of a garbage disposal bag.

[0013] However, bean bags used for sofas, etc. are formed to be much larger in volume and weight than kitchen waste disposal bags, so it is very difficult to lift the bean bag to the position of the funnel formed at the top for separating and discharging the filling, and the filling can easily leak out as the shape of the opening of the bean bag is deformed during the process of separating and discharging the filling.

[0014] And when the opening of a bean bag or temporary filling storage container filled with filling material is connected to the lower funnel, the opening fixedly connected to the lower funnel may be easily separated due to an external force acting due to the weight of a large amount of filling material, resulting in a large leakage of the filling material.

[0015] As another solution to prevent filling material leakage, U.S. Patent Publication No. 2010006177 (published on January 14, 2010) proposes a filling material moving system having auxiliary wings formed of a material that is connected to the opening of the bean bag and can be freely shaped.

[0016] The auxiliary wing connected to the bean bag opening is unfolded to form a connecting port that is inserted into the opening of another bean bag or a temporary filling storage container, and the auxiliary wing is equipped with a fixing member such as a slide fastener so that it can be fixed on the opening of another bean bag or a temporary filling storage container.

[0017] However, in the above-mentioned filling material moving system, if the size of the auxiliary wing and the size of the opening of another bean bag or temporary filling material storage container, which is the target of filling material movement, are different, a gap may be formed when both openings are fixed with a fixing member such as a slide fastener, and if the shape or size of the slide fastener between the openings to be connected are different, there was a problem in that the openings could not be fixed using the fixing member.

[0018] As another solution to prevent leakage of filling material, Republic of Korea Utility Model Publication No. 20-2023-0000596 (published on March 21, 2023) proposes a filling cap for bean bags in which the opening of the packaging container containing the filling material is fixed between the outer surface of a tube guide inserted into the opening of the packaging container and the joint between the tube holder, and a detachable cover is installed on the tube holder.

[0019] A disk-shaped support portion is formed on the outer surface of the tube holder of the filling cap for the above bean bag, so as to catch the opening of the bean bag, and prevent the filling material from leaking when moving the filling material inside the packaging container into the bean bag.

[0020] However, in the case of the filling cap for the above bean bag, since the method of fixing the opening of the packaging container between the outer surface of the tube guide and the joint between the tube holder is applied, there was a problem that the bean bag could be damaged if the opening of the bean bag was fixed between the outer surface of the tube guide and the joint between the tube holder when moving the filling material to another bean bag for washing the bean bag in use.

[0021] In addition, the connector for moving the filling material of the above bean bag may be a product sold independently, or may be a component provided as a secondary component to the bean bag product being sold. If the configuration of the connector becomes complex or its volume increases, the manufacturing cost and product logistics cost may increase together.

[0022] In particular, with the activation of online commerce, the frequency of international shipping for purchases of bean bags from overseas shopping malls is gradually increasing, and in the case of air transportation, the volume weight is applied, which adds shipping costs in proportion to the volume when the volume is large compared to the product weight. Therefore, if the volume of the connector increases, the shipping cost may increase significantly due to the components provided as secondary parts to the product.

[0023] The increasing manufacturing and shipping costs of connectors, which are secondary components, are causing a decline in price competitiveness in online commerce. Therefore, there is a growing need to develop connectors that can achieve product price reductions through structural simplification and volume reduction.

[0024] The purpose of the present invention is to provide a connector structure that can prevent external leakage of filling material when moving filling material between bean bags or between bean bags and a temporary filling material storage container.

[0025] The purpose of the present invention is to provide a connector structure capable of fixing and connecting various types of bean bags regardless of the size or shape of the bean bag, the size or shape of the opening of the bean bag, or the type or size of the fastening member applied to the opening.

[0026] The purpose of the present invention is to provide a connector structure that can improve price competitiveness in online commerce by reducing the manufacturing cost and volume of the connector.

[0063]

[0064] The connector (100) for moving the filler (12) according to the present invention is connected to an opening (10) formed in the receiving member (1) to assist the movement of the filler (12) when filling the filler (12) into the pocket-shaped receiving member (1) in which the filler (12) is filled, discharging the filler (12) filled in the receiving member (1) to the outside of the receiving member (1), or moving the filler (12) filled inside the receiving member (1) to another empty receiving member (1).

[0065] The receiving member (1) in which the connector (100) according to the present invention is used includes various containers in the form of a bean bag, a sack, or a pouch, such as bedding, and the filling material (12) includes cushioning material used in bean bags or bedding, or various raw materials used for manufacturing processed products.

[0066] The receiving member (1) is made of a non-standard container made of fabric material, synthetic or natural leather material and capable of changing shape, and may have a double-layer structure in which the inner skin and the outer skin are combined, or may be made of a single layer.

[0067] Since the movement of the filler (12) is achieved by the weight of the filler (12), the receiving member (1) filled with the filler (12) is placed in the lower direction of the connector (100), and the opening (10) of the receiving member (1) faces upward.

[0068] And the receiving member (1) from which the filler (12) is discharged is arranged in the upper direction of the connector (100), and the opening (10) of the receiving member (1) faces downward.

[0069]

[0070] (A) First embodiment of connection between connector (100) and opening (10):

[0071] In the first embodiment of the connection between the connector (100) and the opening (10), in the case of the receiving member (1) in which the fastening member (11) is formed in the opening (10) itself as shown in FIG. 1, the opening (10) of the receiving member (1) can be caught by the first catch (130) or the second catch (140) of the connector (100).

[0072] Afterwards, when the size of the opening (10) is reduced through the binding member (11), the opening (10) is caught by the first catch (130) or the second catch (140), and the filler (12) can be moved into the receiving member (1) in a state where the opening (10) and the binding member (11) are caught through the binding member (11).

[0073]

[0074] (B) Second embodiment of connection between connector (100) and opening (10):

[0075] The second embodiment of the connection between the connector (100) and the opening (10) is a case where a fastening member (11) is formed in the opening (10) of the receiving member (1) itself, and can be applied when moving the filler (12) stored inside the existing receiving member (1) to the inside of a new receiving member (1).

[0076] As shown in Fig. 2, the openings (10) of the receiving member (1) are connected to the first and second catches (130, 140), respectively, and then the two receiving members (1) can be fixed to the first and second catches (130, 140), respectively, through the fastening member (11).

[0077]

[0078] (C) Third embodiment of connection between connector (100) and opening (10):

[0079] If the fastening member (11) is not formed in the opening (10) of the receiving member (1), the third embodiment of the connection between the connector (100) and the opening (10) can be applied.

[0080] As shown in Fig. 3, by passing the opening (10) of the receiving member (1) through the inside of the hollow portion (110), which is a space formed in the central portion of the connector (100), and then turning the opening (10) over and covering it with the first catch (130) or the second catch (140), the opening (10) of the receiving member (1) can be caught on the first catch (130) or the second catch (140) of the connector (100).

[0081] In order to prevent the end of the opening (10) covered by the first catch (130) or the second catch (140) from being separated, the end of the opening (10) can be fixed with a fastening member (11) such as a cable tie.

[0082] 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 receiving member (1) to the connector (100), the shape and cross-sectional area of ​​the opening (10) of the receiving member (1), which is formed in a pocket shape and is easily subject to deformation, can be maintained constant.

[0083] Through this, when filling the filler (12) into the receiving member (1) or discharging the filler (12) filled in the receiving member (1) to the outside of the receiving member (1), deformation of the opening (10) can be prevented, thereby facilitating the movement of the filler (12).

[0084] 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 method according to the first to third embodiments of the connection between the connector (100) and the opening (10), and it should be understood that a method combining these fixing methods may be applied, or a method other than this may be applied.

[0085] The structure and shape of the connector (100) of the present invention are described as follows.

[0086] As shown in FIGS. 4 and 6, the connector (100) is composed of a support portion (120) having a hollow portion (110) formed in the central portion, and first and second catch portions (130, 140) formed along the outer circumferential surfaces at both ends of the support portion (120).

[0087] The hollow portion (110) forms a passage through which the filler (12) moves when the connector (100) is connected to the receiving member (1) to move the filler (12), and the support portion (120) supports the opening (10) of the receiving member (1), thereby preventing the filler (12) from leaking out through the gap between the connector (100) and the opening (10), or the movement speed of the filler (12) from decreasing due to the area of ​​the opening (10) narrowing due to deformation of the receiving member (1).

[0088] And, when the opening (10) of the receiving member (1) is connected to the connector (100), the first and second catches (130, 140) provide a catch structure that prevents separation between the connector (100) and the receiving member (1) by the opening (10) being caught by the first and second catches (130, 140).

[0089] The support part (120) is formed by a ring-shaped, closed-surface structure of a strip member in the form of a belt surrounding the hollow part (110), and forms a hollow part (110) which is an empty space inside the inner surface of the support part (120), and one end and both ends of the support part (120) are formed open.

[0090] Since the support member (120) is composed of a strip member having a closed surface ring shape, as shown in FIG. 8, a central axis (CS) 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 member (120), is formed.

[0091] A first catch (130) is formed along the outer surface of one end of the open end of the support (120), and the distance from the central axis (CS) of both ends of the hollow portion (110) to the outer edge of the first catch (130) is formed to be greater than the distance from the central axis (CS) of both ends of the hollow portion (110) to the center of the outer surface of the support portion (120), so that the first catch (130) forms a rim structure that protrudes in a direction away from the central axis (CS) of the hollow portion (110).

[0092] A second catch (140) is formed along the outer surface of one end of the support (120) on the open outer surface of the support (120), and the distance from the central axis (CS) of both ends of the hollow portion (110) to the outer edge of the second catch (140) is formed to be greater than the distance from the central axis (CS) of both ends of the hollow portion (110) to the center of the outer surface of the support portion (120), so that the second catch (140) forms a rim structure that protrudes in a direction away from the central axis (CS) of the hollow portion (110).

[0093] The first catch (130) and the second catch (140) are symmetrical with respect to an imaginary plane (S4) formed by connecting the central portions of the two ends of the support (120), and the first and second catch (130, 140) formed along the edges of one end and the other end of the connector (100) form a catch structure to which the opening (10) of one or two receiving members (1) is fixed.

[0094] And as shown in Fig. 10b, the support member (120) has both ends symmetrical to each other based on a virtual plane (S4) formed by connecting the central portions of the two ends of the support member (120).

[0095] In addition, the minimum distance that the protruding ends of the rim formed by the first and second catches (130, 140) are spaced apart from the central axis (CS) of both ends of the hollow portion (110) is formed to be greater than the distance that the open ends of the first and second catches (130, 140) are spaced apart along the central axis (CS) of both ends of the hollow portion (110), i.e., the length of an imaginary line connecting the centers of the open ends of the support portion (120).

[0096] The ratio of the minimum distance that the rim formed by the first and second catches (130, 140) protrudes from the central axis (CS) of the hollow portion (110) and the length of the open ends of the first and second catches (130, 140) can reduce the length of the movement path of the filler (12) inside the connector (100), thereby preventing an increase in the volume of the connector (100).

[0097] By reducing the length of the open ends between the first and second catches (130, 140) of the connector (100), when the opening (10) of the receiving member (1) is connected and fixed to the first and second catches (130, 140), the opening (10) of the receiving member (1) can be prevented from moving along the outer surface of the support member (120), thereby improving the convenience of moving the filler (12).

[0098] And the connector (100) according to the present invention can be a product sold alone, but can also be a component provided as a secondary component to a product such as a bean bag, and as the volume of the connector (100) increases, the manufacturing cost and product logistics cost also increase.

[0099] In particular, with the rise of online commerce, the frequency of international shipping is gradually increasing, and for intercontinental international shipping that cannot be delivered by cargo vehicle, air transportation is mainly used rather than sea transportation, which takes a long time.

[0100] In the case of air transport, since the loading space inside the airplane is limited, if the volume is large compared to the weight of the product, a volume weight is applied that adds a shipping fee in proportion to the volume. However, if the volume of the connector (100) increases, the shipping fee increases significantly due to the connector (100) provided as a secondary part of the product, which may cause a price competitiveness problem in online commerce requiring international shipping.

[0101] Therefore, it is desirable to manufacture the connector (100) from a synthetic resin material including plastic, thereby reducing the unit price and weight of the product at the same time.

[0102]

[0103] (1) First embodiment of connector (100):

[0104] As shown in FIGS. 4, 6, and 16, the cross-sectional shape of the support portion (120) cut along an imaginary plane (S4) formed by connecting the central portions of the two ends of the support portion (120) of the connector (100) may be in the shape of a circle or a regular polygon.

[0105] When the cross-section of the support portion (120) is in the shape of a regular polygon, the filler (12) may leak out through the gap formed between the opening (10) of the receiving member (1) and the outer surface of the support portion (120) during the process of moving the filler (12) through the connector (100). Therefore, it is preferable to apply a cross-sectional shape close to a circle by forming a large number of surfaces on the support portion (120).

[0106] When the opening (10) of the receiving member (1) is connected to the connector (100), a binding member (11) is used to keep the size of the opening (10) constant and prevent the receiving member (1) from being separated from the first catch (130) or the second catch (140).

[0107] The fastening member (11) is made of a member including various strings or cable ties, or is made of a slide fastener formed in the opening (10) itself, and the size of the opening (10) is formed smaller than the rim size formed by the first catch (130) or the second catch (140).

[0108] Through this, the opening (10) is maintained in close contact with the outer surface of the support (120), thereby preventing the filler (12) from leaking out through the gap between the connector (100) and the opening (10).

[0109] However, when moving the filler (12) by connecting and fixing the connector (100) to which the cross-sectional shape of the support portion (120) of the first embodiment is applied through a slide fastener formed in the opening (10) itself, the size of the gap between the connector (100) and the opening (10) may increase as shown in FIG. 13 as the slide fastener moves due to an external force applied to the connector (100) by the weight of the receiving member (1) or the filler (12), and the filler (12) may leak out from the gap.

[0110]

[0111] (2) Second embodiment of connector (100):

[0112] A connector (100) according to the second embodiment is configured such that a first bending portion (101) and a second bending portion (102) are coupled together as shown in FIGS. 5, 7, and 9, and the first bending portion (101) and the second bending portion (102) form a shape that is symmetrical with respect to an imaginary plane (S1) passing through the central axis (CS) of both ends of the hollow portion (110).

[0113] The outer and inner surfaces of the support portion (120) of the first bending portion (101) and the first and second catch 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 catch portions (130, 140) of the second bending portion (102) are bent to form a convex shape toward the outside of the hollow portion (110).

[0114] The longitudinal ends of the first and second bending parts (101, 102) are connected to each other on an imaginary plane (S1), so that the first and second bending parts (101, 102) form one connector (100) member.

[0115] The distance between the protruding rim ends of the supporting portions (120) of the first and second bending portions (101, 102) and the first and second hooking portions (130, 140) from the central axis (CS) varies depending on the length direction of the first and second bending portions (101, 102).

[0116] The distance from the central axis (CS) is maximum at the connection between the first and second bending portions (101, 102) formed on the virtual plane (S1), and minimum at the central portions of each of the first and second bending portions (101, 102), so that the distance between the ends of the connection between the first and second bending portions (101, 102) is formed to be greater than the distance between the central portions of each of the first and second bending portions (101, 102).

[0117] Accordingly, the cross-sectional shape of the support (120) cut along the imaginary plane (S4) formed by connecting the central portions of the two ends of the support (120) of the connector (100) can be formed as shown in FIGS. 16 and 17, in which two parabolic ends are connected symmetrically to each other, or in which two polygonal line segment ends forming an ellipse or an arch shape are connected symmetrically to each other.

[0118] The cross-sectional shape of the connector (100) as in the second embodiment is such that when the receiving member (1) is fixed to the first catch (130) or the second catch (140) through the slide fastener mounted in the opening (10), the joint between the first and second bending portions (101, 102) faces the slide fastener.

[0119] Through this, the angle at which the receiving members (1) on both sides of the opening (10) are separated from each other in a region where the connector (100) is inserted and is not closed by the slide fastener can be narrowed, and the gap size between the connector (100) and the opening (10) due to the external force applied to the connector (100) can be reduced, thereby reducing the amount of filler (12) leaking out during the process of moving the filler (12).

[0120] At this time, when the cross-sectional shape formed by each support portion (120) of the first and second bending portions (101, 102) according to the second embodiment is such that the two arc ends are connected symmetrically with respect to an imaginary plane (S1), the central angle size 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°.

[0121] In addition, when the cross-section of the support portion (120) constituting the first and second bending portions (101, 102) is formed in a form in which the ends of two polygonal line segments forming an arch shape are connected symmetrically to each other, it is preferable to apply a cross-sectional shape close to a form in which the ends of two parabolic lines are connected symmetrically to each other by forming a large number of surfaces formed on the support portion (120) in order to minimize external leakage of the filler (12).

[0122] In particular, when the cross-sectional shape of the support portion (120) is such that the ends of two parabolas are connected symmetrically to each other, or the ends of two polygonal line segments forming an arch shape are connected symmetrically to each other, the connecting portion between the outer peripheral surfaces of each support portion (120) of the first and second bending portions (101, 102) forms a wedge shape.

[0123] One or both ends of the wedge of the outer circumferential joint of the support portion (120) are directed toward the slide fastener applied to the opening (10), and when the opening (10) is closed through the slide fastener, the shape of the wedge of the outer circumferential joint of the support portion (120) further reduces the angle that is opened between the receiving members (1) on both sides in the portion of the opening (10) that is not closed by the insertion of the connector (100), thereby minimizing the size of the gap formed between the connector (100) and the opening (10) compared to other types of cross-sectional shapes of the support portion (120).

[0124] More preferably, the center angle of each arc formed by the support portion (120) of the first and second bending portions (101, 102) can be formed within the range of 130° to 135°, and such an angle allows the filling material (12) to move at an appropriate speed according to the size of the cross-sectional area of ​​the hollow portion (110) of the connector (100), while at the same time reducing the amount of the filling material (12) flowing out through the gap between the opening (10) of the receiving member (1) and the connector (100).

[0125] When 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) becomes narrower, thereby reducing the cross-sectional area of ​​the hollow portion (110), and the amount of movement of the filler (12) moving through the internal space of the hollow portion (110) may be excessively reduced, thereby reducing the usability of the connector (100).

[0126] When 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 receiving members (1) on both sides of the opening (10) are separated from each other in a portion not closed by the slide fastener may increase, and as the receiving members (1) are separated from each other, the slide fastener retreats due to an external force applied, and the filler (12) may leak out through the increased gap between the connector (100) and the opening (10).

[0127] And when the cross-sectional shape of each support part (120) of the first and second bending parts (101, 102) according to the second embodiment is an elliptical shape, the rim ends of the first and second hooking parts (130, 140) of the connecting part between the first and second bending parts (101, 102) are spaced apart from each other by a gap size D L And, the gap size D between the rim ends of the first and second catch portions (130, 140) at the respective central positions of the first and second bending portions (101, 102) s The ratio of D L :Ds can be formed within the range of 1:0.4 to 1:0.8.

[0128] The gap size D between the rim ends of the first and second catches (130, 140) at each central position of the first and second bending parts (101, 102) s The ratio formed by the cross-sectional shape formed by each support portion (120) of the first and second bending portions (101, 102) can be applied not only to a case where the cross-sectional shape is an elliptical shape, but also to a cross-sectional shape where the ends of two parabolic curves are connected symmetrically to each other, or a cross-sectional shape where the ends of two polygonal line segments forming an arch shape are connected symmetrically to each other.

[0129] More preferably D L and D s The ratio can be formed within the range of 1:0.60 to 1:0.70, and such a ratio allows the filling material (12) to move at an appropriate speed according to the size of the cross-sectional area of ​​the hollow portion (110) of the connector (100), while at the same time reducing the amount of the filling material (12) flowing out through the gap between the opening (10) of the receiving member (1) and the connector (100).

[0130] D L and D s When the ratio of the inner surface of the support member (120) is less than 1:0.4, the distance between the central portions of the support member (120) becomes narrower, and the cross-sectional area of ​​the hollow portion (110) decreases, so that the usability of the connector (100) may be reduced due to a decrease in the amount of movement of the filler (12).

[0131] D L and D s When the ratio exceeds 1:0.8, the angle at which the receiving members (1) on both sides of the opening (10) are separated from each other in the area where the closing is not performed by the slide fastener increases, so that the amount of filling material (12) leaking through the increased gap between the connector (100) and the opening (10) may increase.

[0132]

[0133] (3) Third embodiment of connector (100):

[0134] When moving a large amount of filler (12) using a connector (100), such as filling a filler (12) into a large receiving member (1) or discharging a filler (12) from a receiving member (1), the weight of the receiving member (1) and the filler (12) acts as an external force, which may cause deformation of the connector (100).

[0135] In particular, since the connector (100) is manufactured from a synthetic resin material to reduce unit cost and weight, torsional deformation may easily occur due to an external force acting on a part of the connector (100), and when torsional deformation of the connector (100) occurs, the filler (12) may leak out or the connector (100) may be damaged.

[0136] Therefore, in the connector (100) according to the third embodiment, it can be applied to both the connector (100) according to the first embodiment or the second embodiment, and provides a reinforcing structure that increases the rigidity of the connector (100).

[0137] On one outer edge of the first catch (130), a first deformation prevention rib (131) may be formed that protrudes at a certain height in a direction away from the support (120) along the longitudinal direction of the central axis (CS) toward both ends of the hollow portion (110).

[0138] And, on the outer edge of the other end of the second hanging portion (140), a second deformation prevention rib (141) can be formed that protrudes 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).

[0139] The first and second deformation prevention ribs (131, 141) are formed to be symmetrical to each other with an axis of a virtual plane (S4) formed by connecting the central portions of the two ends of the support portion (120) of the connector (100).

[0140]

[0141] (4) Fourth embodiment of connector (100):

[0142] In the connector (100) according to the fourth embodiment, it can be applied to both the connector (100) according to the first embodiment or the second embodiment, and provides a fixing structure that can stably connect the opening (10) of the receiving member (1) through the first and second catches (130, 140).

[0143] As shown in Fig. 10a, the inner surfaces of the rims facing each other of the first and second catches (130, 140) form an inclined surface that is inclined at a certain angle to each other.

[0144] When an imaginary plane that touches the inner surface of the rim facing each other of the first catch (130) or the second catch (140) is defined as plane S2, and an imaginary plane that touches the center point of the outer surface of the support (120) is defined as plane S3, it is preferable that the inner angle at which each plane (S2, S3) intersects is formed within the range of 90° to 140°.

[0145] The connector (100) is manufactured by injection molding using a mold, and the inner surfaces of the first and second catches (130, 140) facing each other and the outer surface of the support (120) are formed by a mold that separates in a direction away from the central axis (CS) after injection molding is completed.

[0146] At this time, if the inner angle at which each plane (S2, S3) intersects is less than 90°, when the mold is separated after injection molding, a catch may occur on the opposing inner surfaces of the rims of the first and second catch portions (130, 140), and 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 a method such as forming a split mold, this may cause an increase in the manufacturing cost of the connector (100) due to an increase in the mold manufacturing cost.

[0147] In addition, when the user moves the filler (12) after connecting the connector (100) to the opening (10) of the receiving member (1), it is necessary to fix the size of the opening (10) through a fastening member (11) in order to prevent the receiving member (1) from being separated from the connector (100).

[0148] Since the fixing of the fastening member (11) is done manually by the user, sufficient free space is required between the rims of the first and second catches (130, 140) for the user's fingers to enter and exit. However, if the inner angle at which each plane (S2, S3) intersects is less than 90°, the spacing between the rims of the first and second catches (130, 140) decreases, thereby reducing the free space required for the fastening of the fastening member (11), which may reduce the user's convenience in using the connector (100).

[0149] And when the openings (10) of the two receiving members (1) are respectively connected to the open ends of the connector (100) to move the filler (12), the weight of the receiving member (1) arranged downward increases as the filler (12) is filled, or a force may be applied in the direction in which the openings (10) of the connector (100) and the receiving member (1) are separated from each other by an external force applied by the user to the receiving member (1) or the connector (100).

[0150] If the inner angle at which each plane (S2, S3) intersects exceeds 140°, the inner slope of the first engaging portion (130) or the second engaging portion (140) forms a perfect angle, so that the engaging action of the opening (10) of the receiving member (1) through the first and second engaging portions (130, 140) may not be properly performed, and when an external force in the direction of separation between the connector (100) and the opening (10) of the receiving member (1) is applied, the receiving member (1) may be easily separated from the connector (100), which may significantly reduce the user's convenience in using the connector (100).

[0151] In addition, the connection portion between the inner surface of the support portion (120) and the outer surface of the first and second catch portions (130, 140) has a chamfered cross-sectional shape to form a gentle curve, and the curved chamfered cross-sectional shape of the connection portion between the support portion (120) and the first and second catch portions (130, 140) prevents the connection portion between the support portion (120) and the first and second catch portions (130, 140) from being damaged due to stress concentration when an external force is applied to the connector (100).

[0152] And the rims of the first and second catches (130, 140) can be configured to have a constant thickness, and accordingly, an external slope corresponding to the slope of the internal slope formed on the inner surface of the rim of the first and second catches (130, 140) can be formed on the outer surface of the rim of the first and second catches (130, 140).

[0153] The external slope formed on the outer surface of the rim of the first and second catch portions (130, 140) is formed in such a way that the distance between the outer surfaces of the rims of the first and second catch portions (130, 140) decreases as it approaches from the protruding rim ends of the first and second catch portions (130, 140) toward the central axis (CS), and the connection portion between the outer surface of the support portion (120) and the inner surface of the first and second catch portions (130, 140) also has a cross-sectional shape that is chamfered to form a gentle curve.

[0154] The external inclined surfaces formed on the rims of the first and second catch portions (130, 140) allow the catch portion (12) caught on the outer surfaces of the first and second catch portions (130, 140) to pass through the openings (10) while moving along the inclined surfaces when the two openings (10) of the receiving member (1) are respectively connected to the open ends of the connector (100) to move the catch portion (12), thereby minimizing the amount of residual catch portion (12) remaining inside the receiving member (1), thereby improving the user's convenience in using the connector (100).

[0155]

[0156] (5) Fifth embodiment of connector (100):

[0157] In the connector (100) according to the fifth embodiment, it can be applied to both the connector (100) according to the first embodiment or the second embodiment, and provides an ideal shape and specification of the first and second engaging portions (130, 140) that can simultaneously achieve reduction in volume and weight of the connector (100) and securing engaging performance of the opening (10) of the receiving member (1) through the first and second engaging portions (130, 140).

[0158] When moving the filler (12) through the connector (100), a concave groove formed by the outer surface of the support portion (120) and the rims of the first and second catch portions (130, 140) is formed along the circumference of the side surface of the connector (100) according to the arrangement direction of the connector (100).

[0159] When the distance between the ends of the rims of the first and second catches (130, 140) is defined as the width of the concave groove, and the shortest distance from the center of the outer surface of the support part (120) to the imaginary line connecting the ends of the rims of the first and second catches (130, 140) is defined as the depth of the concave groove, it is preferable that the ratio of the width of the concave groove formed by the outer surface of the support part (120) and the rims of the first and second catches (130, 140) to the depth of the concave groove be formed within the range of 1:0.7 to 1:4.

[0160] If the ratio of the depth size of the concave groove to the width size of the concave groove is less than 1:0.7, the spacing between each rim of the first and second catches (130, 140) decreases, reducing the free space required for fixing the fastening member (11), which may reduce the user's convenience in using the connector (100).

[0161] In addition, if the ratio of the depth size of the concave groove to the width size of the concave groove exceeds 1:4, the volume of the connector (100) increases in the process of securing the minimum size of the first and second catches (130, 140) to prevent separation between the connector (100) and the opening (10) of the receiving member (1), which may cause an increase in the manufacturing cost of the connector (100) and the unit price of delivery at the logistics stage.

[0162] At this time, the minimum size of the concave groove depth is 10 mm, and by securing the minimum depth size of the concave groove, when moving the filler (12) by connecting the openings (10) of the two receiving members (1) to the open ends of the connector (100), the connector (100) and the openings (10) of the receiving member (1) can be prevented from being separated from each other.

[0163]

[0164] (6) Optimal implementation example of connector (100):

[0165] The optimal embodiment of the connector (100) provides a connector (100) specification range that secures the amount of movement of the filler (12) through the internal space of the hollow portion (110) while preventing an increase in manufacturing cost and logistics cost due to an increase in the volume of the connector (100).

[0166] The cross-sectional shape of the first and second bending portions (101, 102) is formed in a form in which two circular arcs formed by each support portion (120) are connected symmetrically with respect to the plane (S1) according to the second embodiment, and it is preferable that the central angle size of each circular arc is formed within the range of 130° to 134°.

[0167] The gap size D between the rim ends of the first and second hooking parts (130, 140) of the joint between the first and second bending parts (101, 102) L is formed within a range of 250 mm to 270 mm, and the rim ends of the first and second hooking parts (130, 140) at the respective central positions of the first and second bending parts (101, 102) are spaced apart from each other by a gap size D. sis formed within the range of 180 mm to 200 mm.

[0168] The width of the concave groove, which is the distance between the ends of each rim of the first and second catches (130, 140), is formed in the range of 50 mm to 70 mm, and the depth of the concave groove, which is the shortest distance from the center of the outer surface of the support part (120) to the imaginary line segment connecting the ends of each rim of the first and second catches (130, 140), is formed in the range of 20 mm to 40 mm.

[0169]

[0170] The method of moving the filler (12) using the connector (100) according to the first to fifth embodiments or the optimal embodiment configured in this manner is as follows.

[0171] In the second embodiment of the connection between the connector (100) and the opening (10), the filling material (12) filled in the receiving member (1) is moved to another receiving member (1) with an empty interior, and in particular, when the fastening member (11) formed of a slide fastener is formed on the opening (10) of each receiving member (1), the movement of the filling material (12) is carried out in the following steps.

[0172] In the first step, a connector (100) is placed close to the opening (10) of the first receiving member (1).

[0173] In the second step, the second catch (140) of the connector (100) is inserted into the opening (10) so that the end of the opening (10) of the first receiving member (1) is positioned between the first and second catches (130, 140), and then the fastening member (11) formed of a slide fastener is closed to narrow the open area of ​​the opening (10) to a size smaller than the cross-sectional area formed by the rim side end of the second catch (140), thereby fixing the opening (10) on the second catch (140).

[0174] In the third step, the first catch (130) of the connector (100) is placed close to the opening (10) of the second receiving member (1).

[0175] In the fourth step, the first catch (130) of the connector (100) is inserted into the opening (10) so that the end of the opening (10) of the second receiving member (1) is positioned between the first and second catches (130, 140), and then a fastening member (11) formed of a slide fastener is closed to narrow the open area of ​​the opening (10) to a size smaller than the cross-sectional area formed by the rim side end of the first catch (130), thereby fixing the opening (10) on the first catch (130).

[0176] In the fifth step, the receiving member (1) filled with filler (12) and the receiving member (1) with an empty interior are turned over so that the receiving member (1) and the connector (100) are positioned in the vertical direction, and the filler (12) moves toward the receiving member (1) with an empty interior by its own weight.

[0177] When the movement of the filler (1) is completed, in the sixth step, the opening (10) of each receiving member (1) is separated from the connector (100). In order to prevent the filler (12) newly filled in the receiving member (1) from leaking out, the opening (10) of the receiving member (1) newly filled with the filler (12) must be maintained facing upward during the process of separating the connector (100).

[0178] When the separation of the connector (100) from the opening (10) of the newly filled receiving member (1) with the filler (12) is completed, the slide fastener formed in the opening (10) of the newly filled receiving member (1) with the filler (12) is closed to completely close the opening (10), thereby completing the operation of moving the filler (12).

[0179] At this time, the first and second receiving members (1) correspond to either an internally empty receiving member (1) that is filled with filler (12) or a receiving member (1) from which filler (12) is separately discharged.

[0180] In addition, another method of moving the filler (12) using the connector (100) according to the first to fifth embodiments or the optimal embodiment can be performed as follows, and another method of moving the filler (12) is performed by combining the first embodiment and the third embodiment in the connection between the connector (100) and the opening (10).

[0181] In particular, it can be applied in the process of transferring the filler (12) filled in the second receiving member (1) that does not include the self-formed fastening member (11) on the opening (10) to the first receiving member (1) that is empty inside and has the fastening member (11) formed of the slide fastener, or conversely, the filler (12) filled in the first receiving member (1) that is formed with the fastening member (11) formed of the slide fastener, to the second receiving member (1) that is empty inside and does not include the self-formed fastening member (11) on the opening (10).

[0182] In the first step, a connector (100) is placed close to the opening (10) of the second receiving member (1).

[0183] In the second step, as shown in Fig. 3, the end of the opening (10) of the second receiving member (1) is passed through the inside of the hollow portion (110) from the direction of forming the first catch (130), and then a part of the end of the opening (10) of the second receiving member (1) that has passed through the hollow portion (110) is turned over to cover the outer surface of the connector (100).

[0184] In the third step, a separate fastening member (11) separated from the opening (10) of the second receiving member (1) is mounted so as to surround the outer surface of the support member (120) of the connector (100), and the outer surface of the support member (120) and the portion of the second receiving member (1) covering the connector (100) are tightly fixed to each other by the fastening member (11).

[0185] At this time, the binding member (11) of the second receiving member (1) may be made of any one selected from among a cable tie, a string, and a binder, and may also be made of a different type of member than the above-mentioned member as long as it has a similar function.

[0186] In the fourth step, the second catch (140) of the connector (100) is inserted into the opening (10) so that the end of the opening (10) of the first receiving member (1) with an empty interior to be filled with the filler (12) is positioned between the first and second catches (130, 140).

[0187] Afterwards, the fastening member (11) made of a slide fastener is closed to narrow the open area of ​​the opening (10) to a size smaller than the cross-sectional area formed by the rim side end of the second catch (140), thereby fixing the opening (10) on the second catch (140).

[0188] In the fifth step, the second receiving member (1) and the first receiving member (1) are flipped over and the connector (100) is positioned in the vertical direction, respectively, and the filler (12) moves from the second receiving member (1) to the inside of the first receiving member (1) by its own weight.

[0189] When the movement of the filler (1) is completed, the sixth step is performed, in which the opening (10) of each receiving member (1) is separated from the connector (100).

[0190] At this time, if the receiving member (1) into which the filler (12) is vertically filled is the first receiving member (1), the opening (10) of the first receiving member (1) is completely closed by closing the fastening member (11) of the first receiving member (1), and if the receiving member (1) into which the filler (12) is vertically filled is the second receiving member (1), the opening (10) of the second receiving member (1) is closed by a separate fastening member (11), thereby preventing the filler (12) from leaking out.
