Description

[Technical Field]

[0001] The present invention relates to a connector that assists with movement of a filler when the filler is filled inside a pouch-shaped accommodation member such as a bean bag or moved to another pouch, and more particularly, to a connector for moving a filler, which includes a connection part of which an inner circumferential surface has a band-shaped ring shape surrounding a hollow formed in a central portion and both ends are open, a first stopping part formed along an outer circumferential surface of the one open end of the connection part and constituting a rim structure, and a second stopping part formed along an outer circumferential surface of the other open end of the connection part, constituting a rim structure, and having a shape symmetrical to the first stopping part and in which a minimum distance by which the outer circumferential surfaces of the first stopping part and the second stopping part are spaced apart from a central axis toward both ends of the hollow is greater than a distance by which surfaces of both ends of the first stopping part and the second stopping part are spaced apart from each other.[Background Art]

[0002] In a bean bag, which is used as a sofa, a mat, or a cushion, a pouch-shaped fabric or leather accommodation member is filled with a granular filler, and the filler supports a lower portion of the body of a user while moving in a space inside the accommodation member according to the shape of the body.

[0003] Since the filler supports the body while moving according to an external shape of the body, weight is evenly distributed to improve a feeling of use. In particular, when the filler is made of a highly elastic foam material, the filler may be deformed according to the shape of the body, the weight may be more evenly distributed by the filler, and thus a more comfortable feeling of use may be provided.

[0004] When the bean bag is used for a long time, a volume of the filler may be reduced due to occurrence of permanent deformation, and when the volume of the filler is reduced, the feeling of use may be reduced due to the distribution of the weight and a reduction in cushion performance of the bean bag may be reduced, and thus replacement of the filler may be required.

[0005] Further, a situation may occur in which the bean bag should be replaced due to contamination caused by various foreign substances or damage to the bean bag during use of the bean bag. When a use period of the bean bag is short and thus a condition of the filler is good, only the accommodation member of the bean bag may be replaced, and thus costs of replacing the bean bag may be reduced, and the amount of waste generated may be reduced.

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

[0007] In a process of moving the filler filled inside the bean bag to another bean bag or separating and discharging the existing filler from the bean bag and then filling a new filler, the filler may leak from the bean bag in which the filler is to be filled or a temporary filler storage container.

[0008] Due to characteristics of the filler manufactured in a foam processing method to provide a cushion feeling, the filler leaking to the outside is easily scattered according to movement of surrounding air and sticks to a floor due to an attractive force formed by static electricity, making it difficult to collect or clean the leaking filler.

[0009] Further, since the accommodation member of the bean bag is made of a fabric or leather material that may be freely deformed according to the shape of the body of the user, the shape of the opening of the bean bag may also be easily deformed, and the filler may leak out through a gap formed by the deformed opening.

[0010] Further, since a volume of the bean bag used as a sofa is high, when one person or a small number of people move the filler from the opening of the bean bag to an opening of another bean bag which is to be replaced or a temporary filler storage container, it is difficult to maintain a position of the opening constant, and the amount of leaking filler may further increase as the position of the opening is misaligned while moving the filler.

[0011] In order to facilitate accommodation of contents stored inside the pouch-shaped accommodation member that is easily deformed in shape, Japanese Utility Model Registration Publication No. 46024866 (registered on August 27, 1971) presents a funnel for inputting kitchen waste.

[0012] The funnel for inputting kitchen waste is configured such that funnel-shaped protrusions are formed at both ends of a hollow cylindrical body, the kitchen waste input through an upper funnel is collected inside the cylindrical body, and a fixing part for fixing an end of an inlet of a waste disposal bag is formed at a lower funnel.

[0013] However, since a volume and a weight of the bean bag used for a sofa are very high as compared to a kitchen waste disposal bag, it is very difficult to lift up the bean bag for separating and discharging the filler to a position of an upper input funnel. In a process of separating and discharging the filler, the opening of the bean bag may be deformed, and thus the filler may easily leak.

[0014] Further, when the opening of the bean bag filled with the filler or the temporary filler storage container is connected to the lower funnel, the opening fixedly connected to the lower funnel by an external force applied due to a weight of the large amount of the filler may be easily separated, and thus the large amount of the filler may leak.

[0015] As another solution for preventing the leakage of the filler, U.S. Patent Application Publication No. 2010006177 (disclosed on January 14, 2010) proposes a filler moving system that has an auxiliary wing that is connected to the opening of the bean bag and made of a material whose shape is freely deformable.

[0016] A connector inserted into another bean bag or the temporary filler storage container may be formed as the auxiliary wing connected to the opening of the bean bag is unfolded, and the auxiliary wing may be equipped with a fixing member such as a slide fastener and thus fixed to the opening of another bean bag or the temporary filler storage container.

[0017] However, in the filler moving system, when the size of the auxiliary wing is different from the size of the opening of another bean bag to which the filler is to be moved or the temporary filler storage container, when both openings are fixed using a fixing member such as a slide fastener, a gap may be formed, and when shapes and specifications of the slide fastener between the openings connected to each other are different, the opening may not be fixed through the fixing member.

[0018] As still another solution for preventing the leakage of the filler, Korean Open Utility Model Publication No. 10-2023-0000596 (disclosed on March 21, 2023) proposes a bean bag filling cap in which a packaging container opening is fixed between an outer circumferential surface of a tube guide inserted into the packaging container opening including the filler and a coupling part between tube holders and a detachable cover is mounted on the tube holder.

[0019] A disk-shaped support is formed on the outer circumferential surface of the tube holder of the bean bag filling cap to stop the opening of the bean bag and to prevent the leakage of the filler when the filler inside the packaging container is moved into the bean bag.

[0020] However, in the case of the bean bag filling cap, since a method of fixedly inserting the packaging container opening between the outer circumferential surface of the tube guide and the coupling part between the tube holders is applied, when the filler is moved to another bean bag for washing the bean bag in use, when the opening of the bean bag is fixedly inserted between the outer circumferential surface of the tube guide and the coupling part between the tube holders, the bean bag may be damaged.

[0021] Further, the connector for moving the filler of the bean bag may be a product sold alone or a component provided secondarily to the bean bag that is a sold product, and when the connector becomes complicated or a volume thereof is increased, manufacturing costs and product logistics costs may also increase.

[0022] In particular, with the activation of online commerce, the frequency of international deliveries due to purchasing a bean bag from an overseas shopping mall is gradually increasing, and in the case of air transportation, when the volume is large compared to the weight of the product, a volume weight that adds to a transportation fee in proportion to the volume is applied, and thus when the volume of the connector is increased, the transportation fee may greatly increase due to the component secondarily provided in the product.

[0023] Increases in manufacturing costs and delivery costs of the connector that is the secondarily provided component cause a decrease in price competitiveness in online commerce, and thus a need for developing a connector that may achieve a decrease in a product price due to simplification of a structure and a decrease in the volume is gradually increasing.[Disclosure][Technical Problem]

[0024] The present invention is directed to providing a connector structure capable of preventing occurrence of leakage of a filler to the outside when the filler is moved between bean bags or between the beanbag and a temporary filler storage container.

[0025] The present invention is also directed to providing a connector structure capable of fixedly connecting various types of bean bags regardless of a size or shape of a bean bag, a size or shape of an opening of the bean bag, and a type or size of a binding member applied to the opening.

[0026] The present invention is also directed to providing a connector structure capable of improving price competitiveness in online commerce by reducing manufacturing costs and a volume of a connector.[Technical Solution]

[0046] However, even in this case, it does not mean that the corresponding component has different functions according to the embodiments or has the same function in different embodiments, and the function of the component should be determined based on the description of the component in the corresponding embodiment.

[0047] Further, technical terms used in the specification should be interpreted with meanings that are generally understood by those skilled in the art to which the present invention belongs unless otherwise specifically defined in the specification and should not be interpreted with excessively comprehensive meanings or excessively reduced meanings.

[0048] Further, a singular expression used in the specification includes plural expressions unless otherwise indicated in the context.

[0049] In the present application, terms such as "consists of" or "includes" should not necessarily be construed as including all components or operations described in the specification and should be construed as not including some components or some operations or as further including additional components or additional operations.

[0050] A connector 100 for moving a filler 12 according to the present invention is connected to an opening 10 formed in an accommodation member 1 to assist with movement of the filler 12 when the filler 12 is filled into the pouch-shaped accommodation member 1 into which the filler 12 is filled, when the filler 12 filled in the accommodation member 1 is discharged to the outside of the accommodation member 1, or when the filler 12 filled into the accommodation member 1 is moved to another empty accommodation member 1.

[0051] The accommodation member 1 in which the connector 100 according to the present invention is used includes various pouch-type containers such as a bean bag, a bag, or bedding, and the filler 12 includes cushion materials used for the bean bag or the bedding or various raw materials used for manufacturing processed products.

[0052] The accommodation member 1 may be formed as an irregularly shaped container which is made of a fabric material or a synthetic or natural leather material and of which a shape may be changed and may be formed as a double layer structure in which an inner skin and an outer skin are coupled to each other or may be formed as a single layer.

[0053] Since the filler 12 is moved by a self-weight of the filler 12, the accommodation member 1 in which the filler 12 is filled is disposed downward from the connector 100, and the opening 10 of the accommodation member 1 faces upward.

[0054] Further, the accommodation member 1 from which the filler 12 is discharged is disposed upward from the connector 100, and the opening 10 of the accommodation member 1 faces downward.(A) First embodiment for connection between connector 100 and opening 10:

[0055] In the first embodiment for connection between the connector 100 and the opening 10, as illustrated in FIG. 1, in the case of the accommodation member 1 in which a binding member 11 is formed in the opening 10 itself, the opening 10 of the accommodation member 1 may be stopped by the first stopping part 130 or the second stopping part 140.

[0056] Thereafter, when a size of the opening 10 is reduced through the binding member 11, the opening 10 may be stopped by the first stopping part 130 or the second stopping part 140, and the filler 12 may be moved into the accommodation member 1 while the opening 10 and the binding member 11 are stopped therebetween through the binding member 11.(B) Second embodiment for connection between connector 100 and opening 10:

[0057] The second embodiment for connection between the connector 100 and the opening 10 may correspond to a case in which the binding member 11 is formed in the opening 10 itself of the accommodation member 1 and may be applied when the filler 12 stored inside the existing accommodation member 1 is moved into a new accommodation member 1.

[0058] As illustrated in FIG. 2, after the openings 10 of the accommodation members 1 are connected to the first stopping part 130 and the second stopping part 140, both of the accommodation members 1 may be fixed to the first stopping part 130 and the second stopping part 140 through the binding member 11.(C) Third embodiment for connection between connector 100 and opening 10:

[0059] When the binding member 11 is not formed in the opening 10 itself of the accommodation member 1, the third embodiment for connection between the connector 100 and the opening 10 may be applied.

[0060] As illustrated in FIG. 3, after the opening 10 of the accommodation member 1 passes through the inside of a hollow 110 that is a space formed in a center of the connector 100, the opening 10 may be turned over and then covered on the first stopping part 130 or the second stopping part 140, and thus the opening 10 of the accommodation member 1 may be stopped by the first stopping part 130 or the second stopping part 140 of the connector 100.

[0061] In order to prevent an end of the opening 10 covered on the first stopping part 130 or the second stopping part 140 from being separated, the end of the opening 10 may be fixed with the binding member 11 such as a cable tie.

[0062] According to the first embodiment, the second embodiment, and the third embodiment for connection between the connector 100 and the opening 10, the opening 10 of the accommodation member 1 may be fixed to the connector 100, and thus a shape and a cross-sectional area of the opening 10 of the accommodation member 1 that is formed in a pouch shape and is easily deformed may be maintained constant.

[0063] Therefore, when the filler 12 is filled inside the accommodation member 1 or the filler 12 filled in the accommodation member 1 is discharged to the outside of the accommodation member 1, occurrence of deformation of the opening 10 may be prevented, thereby facilitating the movement of the filler 12.

[0064] A method of fixing the opening 10 of the accommodation member 1 to the connector 100 according to the present invention is not limited to the methods according to the first embodiment, the second embodiment, and the third embodiment for connection between the connector 100 and the opening 10, and it should be understood that a method obtained by combining these fixing methods may be applied or a different method may be applied.

[0065] A structure and a shape of the connector 100 of the present invention will now be described.

[0066] As illustrated in FIGS. 4 and 6, the connector 100 includes a support 120 having the hollow 110 formed in a center thereof and the first stopping part 130 and the second stopping part 140 formed along outer circumferential surfaces of both ends of the support 120.

[0067] The hollow 110 connects the connector 100 to the accommodation member 1 to form a passage through which the filler 12 is moved when the filler 12 is moved, the support 120 supports the opening 10 of the accommodation member 1, and thus the filler 12 is prevented from leaking into a gap between the connector 100 and the opening 10 or a moving speed of the filler 12 is prevented from decreasing as an area of the opening 10 narrows due to deformation of the accommodation member 1.

[0068] Further, the first stopping part 130 and the second stopping part 140 provide a stopping structure that prevents separation between the connector 100 and the accommodation member 1 as the opening 10 is stopped by the first stopping part 130 and the second stopping part 140 when the opening 10 of the accommodation member 1 is connected to the connector 100.

[0069] In the support 120, while a strip member in the form of a band surrounding the hollow 110 forms a ring shape having a closed surface structure, the hollow 110 that is an empty space inside an inner circumferential surface of the support 120 is formed, and one end and both ends of the support 120 are open.

[0070] Since the support 120 is configured by a strip member that forms a closed surface ring shape, as illustrated in FIG. 8, a central axis CS in directions of both open ends of the hollow 110, which is an imaginary line segment connecting centers at both open ends of the support 120 is formed.

[0071] The first stopping part 130 is formed along an outer circumferential surface of the one end of the support 120 on the outer circumferential surface of the one open end of the support 120, a separation distance from the central axis CS in directions of both ends of the hollow 110 to an edge at an outer end of the first stopping part 130 is greater than a separation distance from the central axis CS in the directions of both ends of the hollow 110 to a central portion of the outer circumferential surface of the support 120, and the first stopping part 130 forms a rim structure protruding away from the central axis CS of the hollow 110.

[0072] The second stopping part 140 is formed along the outer circumferential surface of the one end of the support 120 on the outer circumferential surface of the other open end of the support 120, a separation distance from the central axis CS in the directions of both ends of the hollow 110 to an edge at an outer end of the second stopping part 140 is greater than a separation distance from the central axis CS in the directions of both ends of the hollow 110 to the central portion of the outer circumferential surface of the support 120, and the second stopping part 140 forms a rim structure protruding away from the central axis CS of the hollow 110.

[0073] The first stopping part 130 and the second stopping part 140 are symmetrical to each other based on an imaginary plane S 4 formed by connecting central portions of the support 120 in directions of both ends, and the first stopping part and the second stopping part 140 formed along edges of one end and the other end of the connector 100 form a stopping structure in which the opening 10 of one or two accommodation members 1 is fixed.

[0074] Further, as illustrated in FIG. 10B, both ends of the support 120 are symmetrical to each other based on the imaginary plane S 4 formed by connecting the central portions of the support 120 in the directions of both ends.

[0075] Further, a minimum distance by which a protruding end of the rim formed by the first stopping part 130 and the second stopping part 140 is spaced apart from the central axis CS of the hollow 110 in the directions of both ends is greater than a distance by which both open ends of the first stopping part 130 and the second stopping part 140 are spaced apart from the central axis CS of the hollow 110 in the directions of both ends, i.e., a length of an imaginary line segment connecting centers of both open ends of the support 120.

[0076] The minimum distance by which the rim formed by the first stopping part 130 and the second stopping part 140 protrudes from the center axis CS of the hollow 110 and a ratio between lengths of the first stopping part 130 and the second stopping part 140 in both open ends may reduce a length of a moving passage for the filler 12 inside the connector 100 to prevent an increase in a volume of the connector 100.

[0077] When a length between both open ends of the first stopping part 130 and the second stopping part 140 of the connector 100 is reduced and the opening 10 of the accommodation member 1 is fixedly connected to the first stopping part 130 and the second stopping part 140, the opening 10 of the accommodation member 1 may be prevented from moving along the outer circumferential surface of the support 120, and therefore convenience of moving the filler 12 can be improved.

[0078] Further, the connector 100 according to the present invention is not only a product sold alone but also a component provided secondarily to a product of the accommodation member 1 such as a bean bag. When the volume of the connector 100 is increased, manufacturing costs and product logistics costs also increase.

[0079] In particular, with the activation of online commerce, the frequency of international deliveries is gradually increasing, and in the case of intercontinental international deliveries in which delivery by freight vehicle is not possible, air transportation is mainly used rather than ship transportation which takes a longer delivery period.

[0080] In the case of air transportation, since a loading space inside an airplane is limited, a volume weight that adds to a transportation fee in proportion to a volume is applied when the volume is large compared to a product weight. When the volume of the connector 100 increases, the transportation fee increases significantly due to the connector 100 provided secondarily to the product, and thus price competitiveness in online commerce that requires international delivery may be reduced.

[0081] Thus, it is preferable to reduce both a unit price and a weight of the product by manufacturing the connector 100 of a synthetic resin material containing plastic.(1) First embodiment of connector 100:

[0082] As illustrated in FIGS. 4, 6, and 16, a cross-sectional shape of the support 120 cut along the imaginary plane S 4 formed by connecting central portions of the connector 100 in the directions of both ends of the support 120 may be a circular shape or a regular polygonal shape.

[0083] When the cross-section of the support 120 has a regular polygonal shape, it is preferable that a cross-sectional shape similar to a circular shape be applied by forming a plurality of surfaces formed on the support 120 because the filler 12 may leak through a gap between the opening 10 of the accommodation member 1 and the outer circumferential surface of the support 120 in a process of moving the filler 12 through the connector 100.

[0084] When the opening 10 of the accommodation member 1 is connected to the connector 100, the binding member 11 is used to prevent the accommodation member 1 from being separated from the first stopping part 130 or the second stopping part 140 by maintaining the size of the opening 10 constant.

[0085] The binding member 11 is formed by a member including various strings or cable ties or formed by a slide fastener formed in the opening 10 itself, and the size of the opening 10 is formed smaller than a size of the rim formed by the first stopping part 130 or the second stopping part 140.

[0086] Therefore, the opening 10 is maintained in close contact with the outer circumferential surface of the support 120, thereby preventing the filler 12 from leaking through the gap between the connector 100 and the opening 10.

[0087] However, when the filler 12 is moved while the connector 100, to which the cross-sectional shape of the support 120 which is a circular shape or a regular polygonal shape according to the first embodiment is applied, is fixedly connected through the slide fastener formed in the opening 10 itself, as the slide fastener is moved by an external force applied to the connector 100 by the weight of the accommodation member 1 or the filler 12, as illustrated in FIG. 13, a size of the gap between the connector 100 and the opening 10 may increase, and the filler 12 may leak from the gap.(2) Second embodiment of connector 100:

[0088] As illustrated in FIGS. 5, 7, and 9, the connector 100 according to the second embodiment is configured such that a first bending part 101 and a second bending part 102 are coupled to each other, and the first bending part 101 and the second bending part 102 are symmetrical to each other based on an imaginary plane S 1 passing through the central axis CS of the hollow 110 in the directions of both ends.

[0089] The outer circumferential surface and the inner circumferential surface of the support 120 of the first bending part 101 and the first stopping part 130 and the second stopping part 140 are bent to form a convex shape toward the outside of the hollow 110, and the support 120 of the second bending part 102 and the outer circumferential surface and the inner circumferential surface of the first and second stopping parts 130 and 140 are bent to form a convex shape toward the outside of the hollow 110.

[0090] Both ends of the first bending part 101 and the second bending part 102 in a longitudinal direction are connected to each other on the imaginary plane S 1 , and thus the first bending part 101 and the second bending part 102 form one member of the connector 100.

[0091] A distance by which protruding rim ends of the first stopping part 130 and the second stopping part 140 and the support 120 of the first bending part 101 and the second bending part 102 are spaced apart from the central axis CS with respect to portions of the first bending part 101 and the second bending part 102 in a longitudinal direction is changed.

[0092] The distance from the central axis CS has a maximum value at a connection portion between the first bending part 101 and the second bending part 102 formed on the imaginary plane S 1 and has a minimum value at central portions of the first bending part 101 and the second bending part 102, and an interval by which both ends of a coupling part between the first bending part 101 and the second bending part 102 are spaced apart from each other is greater than an interval by which the central portions of the first bending part 101 and the second bending part 102 are spaced apart from each other.

[0093] Accordingly, as illustrated in FIGS. 16 and 17, the cross-sectional shape of the support 120 cut along the imaginary plane S 4 formed by connecting the central portions of the connector 100 in the directions of both ends of the support 120 may be a shape in which ends of two parabolas are connected to be symmetrical to each other or a shape in which ends of two polygonal line segments constituting an elliptical shape or an arch shape are connected to be symmetrical to each other.

[0094] In a cross-sectional shape of the connector 100 according to the second embodiment, when the accommodation member 1 is fixed to the first stopping part 130 or the second stopping part 140 through the slide fastener mounted on the opening 10, the coupling part between the first bending part 101 and the second bending part 102 faces the slide fastener.

[0095] Therefore, a size of an angle at which the accommodation member 1 is widened on both sides of the opening 10 at a portion into which the connector 100 is inserted and which is not closed by the slide fastener may be decreased. The size of the gap between the connector 100 and the opening 10 due to an external force applied to the connector 100 may be reduced, and thus the amount of leakage of the filler 12 generated in a process of moving the filler 12 may be reduced.

[0096] In this case, when the cross-sectional shape of the support 120 formed by the first bending part 101 and the second bending part 102 according to the second embodiment is a shape in which ends of two arcs are connected symmetrically to each other based on the imaginary plane S 1 , a central angle of an arc formed by the first bending part 101, the second bending part 102, and the support 120 may be in a range of 100° to 150°.

[0097] Further, when a cross section of the support 120 constituting the first bending part 101 and the second bending part 102 is a shape in which ends of two polygonal line segments constituting an arch shape are connected symmetrically to each other, it is preferable to apply a cross-sectional shape similar to the shape in which the ends of the two parabolas are connected symmetrically to each other so that a plurality of surfaces are formed on the support 120 to minimize the leakage of the filler 12 to the outside.

[0098] In particular, when the cross-sectional shape of the support 120 is a shape in which the ends of the two parabolas are connected symmetrically to each other or a shape in which the ends of the two polygonal line segments constituting the arch shape are connected symmetrically to each other, a coupling part between the outer circumferential surfaces of the support 120 of the first bending part 101 and the second bending part 102 has a wedge shape.

[0099] One end or both ends of the wedge of the coupling part between the outer circumferential surfaces of the support 120 face the slide fastener applied to the opening 10. When the opening 10 is closed through the slide fastener, an angle between the accommodation members 1 at a portion of the opening 10 that is not closed by inserting the connector 100 may be further reduced through the wedge shape of the coupling part between the outer circumferential surfaces of the support 120, and thus the size of the gap formed between the connector 100 and the opening 10 may be minimized compared to the cross-sectional shape of the support 120 having another form.

[0100] More preferably, a size of the central angle of the arc formed by the first bending part 101, the second bending part 102, and the support 120 may be in a range of 130° to 135°, and this angle may appropriately maintain the moving speed of the filler 12 according to the size of the cross-sectional area of the hollow 110 of the connector 100, and at the same time, may reduce the amount of the filler 12 leaking through a gap of a connection part between the opening 10 of the accommodation member 1 and the connector 100.

[0101] When the size of the central angle of the arc formed by the support 120 of the first bending part 101 and the second bending part 102 is smaller than 100°, as an interval by which central portions of inner circumferential surfaces of the support 120 are spaced apart from each other is reduced, the cross-sectional area of the hollow 110 may be reduced, and as the amount of movement of the filler 12 moved through an internal space of the hollow 110 is excessively reduced, use convenience of the connector 100 may be degraded.

[0102] When the size of the central angle of the arc formed by the support 120 of the first bending part 101 and the second bending part 102 is greater than 150°, the size of the angle at which the accommodation member 1 is widened on both sides of the opening 10 at a portion that is not closed by the slide fastener may be increased. The slide fastener retreats due to an external force applied as the accommodation member 1 is widened, and thus the filler 12 may leak out through an increased gap between the connector 100 and the opening 10.

[0103] Further, when the cross-sectional shape of the support 120 of the first bending part 101 and the second bending part 102 according to the second embodiment is an elliptical shape, a ratio between an interval D L by which rim ends of the first stopping part 130 and the second stopping part 140 at the coupling part between the first bending part 101 and the second bending part 102 are spaced apart from each other and an interval D S by which the rim ends of the first stopping part 130 and the second stopping part 140 at central positions of the first bending part 101 and the second bending part 102 are spaced apart from each other, i.e., D L :D S , may be formed in a range of 1:04 to 1:08.

[0104] The ratio of the interval D S by which the rim ends of the first stopping part 130 and the second stopping part 140 at the central positions of the first bending part 101 and the second bending part 102 are spaced apart from each other may be applied when the ends of the two parabolas are connected symmetrically to each other or when the ends of the two polygonal line segments constituting the arch shape are connected symmetrically to each other as well as when the cross-sectional shape of the support 120 of the first bending part 101 and the second bending part 102 is an elliptical shape.

[0105] More preferably, the ratio between D L and D S may be formed in a range of 1:0.60 to 1:0.70, and this ratio may appropriately maintain the moving speed of the filler 12 according to the size of the cross-sectional area of the hollow 110 of the connector 100, and at the same time, may reduce the amount of the filler 12 leaking through the gap of the connection part between the opening 10 of the accommodation member 1 and the connector 100.

[0106] When the ratio between D L and D S is smaller than 1:0.4, the cross-sectional area of the hollow 110 may be reduced as an interval by which the central portions of the inner circumferential surfaces of the support 120 are spaced apart from each other is reduced, and thus use convenience of the connector 100 may be degraded according to a decrease in the amount of movement of the filler 12.

[0107] When the ratio between D L and D S is greater than 1:0.8, the size of the angle at which the accommodation member 1 is widened on both sides of the opening 10 at the portion that is not closed by the slide fastener may be increased, and thus the amount of leakage of the filler 12 may be increased through the increased gap between the connector 100 and the opening 10.(3) Third embodiment of connector 100:

[0108] When a large amount of the filler 12 is moved using the connector 100, for example, when the large accommodation member 1 is filled with the filler 12 or when the filler 12 is discharged from the accommodation member 1, the weights of the accommodation member 1 and the filler 12 may act as an external force, and thus the connector 100 may be deformed.

[0109] In particular, since the connector 100 is manufactured of a synthetic resin to reduce the unit price and the weight, torsional deformation due to an external force applied to a portion of the connector 100 may easily occur, and when the torsional deformation of the connector 100 occurs, the filler 12 may leak to the outside or the connector 100 may be damaged.

[0110] Thus, the connector 100 according to the third embodiment may be applied as the connectors 100 according to both the first embodiment and the second embodiment and provides a reinforcing structure that increases rigidity of the connector 100.

[0111] A first deformation preventing rib 131 protruding away from the support 120 to a predetermined height in a longitudinal direction of the central axis CS in the directions of both ends of the hollow 110 may be formed at an outer edge of one end of the first stopping part 130.

[0112] Further, a second deformation preventing rib 141 protruding away from the support 120 to a predetermined height in a longitudinal direction of the central axis CS in the directions of both ends of the hollow 110 may be formed at an outer edge of the other end of the second stopping part 140.

[0113] The first deformation preventing rib 131 and the second deformation preventing rib 141 may have symmetrical shapes based on the imaginary plane S 4 formed by connecting the central portions of the connector 100 in the directions of both ends of the support 120.(4) Fourth embodiment of connector 100:

[0114] The connector 100 according to the fourth embodiment may be applied as the connectors 100 according to both the first embodiment and the second embodiment and provides a fixing structure capable of stably connecting the opening 10 of the accommodation member 1 through the first stopping part 130 and the second stopping part 140.

[0115] As illustrated in FIG. 10A, inner surfaces of rims that face each other of the first stopping part 130 and the second stopping part 140 form inclined surfaces that are inclined to form a predetermined angle therebetween.

[0116] When an imaginary plane in contact with the inner surfaces of the rims that face each other of the first stopping part 130 or the second stopping part 140 is defined as a plane S 2 , and an imaginary plane in contact with a central point of the outer circumferential surface of the support 120 is defined as a plane S 3 , it is preferable that an angle of an inner side intersecting the planes S 2 and S 3 be formed in a range of 90° to 140°.

[0117] The connector 100 is manufactured in an injection molding method through a mold, and the inner surfaces that face each other of the first stopping part 130 and the second stopping part 140 and the outer circumferential surface of the support 120 are formed by the mold separated away from the central axis CS after the injection molding method is completed.

[0118] In this case, when the angle of the inner side intersecting the planes S 2 and S 3 is smaller than 90° and the mold is separated after the injection molding method, the inner surfaces of the rims that face each other of the first stopping part 130 and the second stopping part 140 may be stopped. When the stopping between the mold and the inner surfaces of the rims of the first stopping part 130 and the second stopping part 140 is avoided through a method of dividing and forming the mold, manufacturing costs of the connector 100 may be increased due to an increase in manufacturing costs of the mold.

[0119] Further, when a user moves the filler 12 after connecting the connector 100 to the opening 10 of the accommodation member 1, a size of the opening 10 needs to be fixed through the binding member 11 to prevent the accommodation member 1 from being separated from the connector 100.

[0120] Since fixing by the binding member 11 is performed manually by the user, spare space sufficient for a finger of the user to enter and exit may be required between the rims of the first stopping part 130 and the second stopping part 140. When the angle of the inner side intersecting the planes S 2 and S 3 is smaller than 90°, an interval by which the rims of the first stopping part 130 and the second stopping part 140 may be spaced apart from each other is decreased, spare space required for fixing by the binding member 11 may be reduced, and thus use convenience of the connector 100 for the user may be reduced.

[0121] Further, when the filler 12 is moved while the openings 10 of the two accommodation members 1 are connected to both open ends of the connector 100, the weight is increased as the filler 12 is filled in the accommodation member 1 disposed on a lower side or the user may apply a force in a direction in which the connector 100 and the openings 10 of the accommodation members 1 are separated from each other by an external force applied to the accommodation members 1 or the connector 100.

[0122] When the angle of the inner side intersecting the plane S2 and S3 is greater than 140°, an inner inclined surface of the first stopping part 130 or the second stopping part 140 has a flat angle, and thus the opening 10 of the accommodation member 1 may not be properly stopped through the first stopping part 130 and the second stopping part 140. When an external force is applied in a direction in which the connector 100 and the opening 10 of the accommodation member 1 are separated from each other, the accommodation member 1 may be easily separated from the connector 100, and thus the use convenience of the connector 100 for the user may be greatly reduced.

[0123] Further, a connection part between the inner circumferential surface of the support 120 and outer surfaces of the first stopping part 130 and the second stopping part 140 forms a chamfered cross-sectional shape to form a smooth curved surface. A curved chamfered cross-sectional shape of the connection part between the support 120 and the first stopping part 130 and the second stopping part 140 prevents damage to the connection part between the support 120 and the first stopping part 130 and the second stopping part 140 due to stress concentration when an external force is applied to the connector 100.

[0124] Further, the rims of the first stopping part 130 and the second stopping part 140 may be configured to have a constant thickness, and accordingly, an external inclined surface corresponding to an inclination of the inner inclined surface formed on the inner surfaces of the rims of the first stopping part 130 and the second stopping part 140 may be formed on the outer surfaces of the rims of the first stopping part 130 and the second stopping part 140.

[0125] An outer inclined surface formed on an outer surface of the rims of the first stopping part 130 and the second stopping part 140 forms a shape in which a separation interval between the outer surfaces of the rims of the first stopping part 130 and the second stopping part 140 is decreased as they are moved from the protruding rim ends of the first stopping part 130 and the second stopping part 140 in a direction of the central axis CS. The connection part between the outer circumferential surface of the support 120 and the inner surfaces of the first stopping part 130 and the second stopping part 140 also forms a chamfered cross-sectional shape to form a smooth curved surface.

[0126] The outer inclined surface formed in the rims of the first stopping part 130 and the second stopping part 140 connects the openings 10 of the two accommodation members 1 to both open ends of the connector 100, and when the filler 12 is moved, the filler 12 stopped by the outer surfaces of the first stopping part 130 and the second stopping part 140 passes through the opening 10 while moving along an inclined surface, the amount of the generated filler 12 remaining inside the accommodation member 1 is minimized, and thus the use convenience of the connector 100 for the user is improved.(5) Fifth embodiment of connector 100:

[0127] The connector 100 according to the fifth embodiment may be applied as the connectors 100 according to both the first embodiment and the second embodiment and provides an ideal shape and standard of the first stopping part 130 and the second stopping part 140 capable of simultaneously reducing the volume and the weight of the connector 100 and securing stopping performance of the opening 10 of the accommodation member 1 through the first stopping part 130 and the second stopping part 140.

[0128] Concave grooves formed by the outer circumferential surface of the support 120 and the rims of the first stopping part 130 and the second stopping part 140 are formed on a side surface of the connector 100 according to an arrangement direction of the connector 100 along a circumference of the side surface of the connector 100.

[0129] When a distance by which the rims ends of the first stopping part 130 and the second stopping part 140 are spaced apart from each other is defined as a width of the concave groove, and a minimum distance from the central portion of the outer circumferential surface of the support 120 to an imaginary line segment connecting the rim ends of the first stopping part 130 and the second stopping part 140 is defined as a depth of the concave groove, it is preferable that a ratio of the depth of the concave groove to the width of the concave groove formed by the outer circumferential surface of the support 120 and the rims of the first stopping part 130 and the second stopping part 140 be formed in a range of 1:07 to 1:4.

[0130] When the ratio of the depth of the concave groove to the width of the concave groove is smaller than 1:0.7, an interval by which the rims of the first stopping part 130 and the second stopping part 140 are spaced apart from each other may be decreased, spare space required for fixing by the binding member 11 may be reduced, and thus the use convenience of the connector 100 for the user is reduced.

[0131] Further, when the ratio of the depth of the concave groove to the width of the concave groove is greater than 1:4, the volume of the connector 100 is increased in a process of securing a minimum size of the first stopping part 130 and the second stopping part 140 for preventing occurrence of separation between the connector 100 and the opening 10 of the accommodation member 1, and thus an increase in manufacturing costs of the connector 100 and an increase in delivery costs in a logistics stage may be caused.

[0132] In this case, a minimum depth of the concave groove is 10 mm, and by securing the minimum depth of the concave groove, when the filler 12 is moved while the openings 10 of the two accommodation members 1 are connected to both open ends of the connector 100, the connector 100 and the openings 10 of the accommodation members 1 may be prevented from being separated from each other.(6) Optimum embodiment of connector 100:

[0133] The connector 100 according to the optimum embodiment provides a standard range of the connector 100 for securing the amount of movement of the filler 12 through the internal space of the hollow 110, and at the same time, preventing an increase in manufacturing costs and an increase in logistics costs due to an increase in the volume of the connector 100.

[0134] It is preferable that the cross-sectional shapes of the first bending part 101 and the second bending part 102 be connected such that two arcs formed by the support 120 are symmetrical to each other based on the plane S1 according to the second embodiment and a size of a central angle of each arc is formed in a range of 130° to 134°.

[0135] The interval D L by which the rim ends of the first stopping part 130 and the second stopping part 140 at the coupling part between the first bending part 101 and the second bending part 102 are spaced apart from each other is formed in a range of 250 mm to 270 mm, and the interval D S by which the rim ends of the first stopping part 130 and the second stopping part 140 at central positions of the first bending part 101 and the second bending part 102 are spaced apart from each other is formed in a range of 180 mm to 200 mm.

[0136] The width of the concave groove, which is a distance by which the rim ends of the first stopping part 130 and the second stopping part 140 are spaced apart from each other, is formed in a range of 50 mm to 70 mm, and the depth of the concave groove, which is a shortest distance from the central portion of the outer circumferential surface of the support 120 to the imaginary line segment connecting the rim ends of the first stopping part 130 and the second stopping part 140, is formed in a range of 20 mm to 40 mm.

[0137] A method of moving the filler 12 using the connector 100 according to the first to fifth embodiments and the optimum embodiment will now be described.

[0138] According to the second embodiment for connection between the connector 100 and the opening 10, in a process of moving the filler 12 filled in the accommodation member 1 to another accommodation member 1 having an empty interior, particularly, when the binding member 11 including the slide fastener is formed on the opening 10 of the accommodation member 1, the filler 12 is moved in the following operations.

[0139] In a first operation, the connector 100 is disposed close to the opening 10 of a first accommodation member 1.

[0140] In a second operation, after the second stopping part 140 of the connector 100 is inserted into the opening 10 so that the end of the opening 10 of the first accommodation member 1 is positioned between the first stopping part 130 and the second stopping part 140, an open area of the opening 10 is decreased as compared to a cross-sectional area formed by an end of a side surface of the rim of the second stopping part 140 by closing the binding member 11 including the slide fastener, and thus the opening 10 is fixed onto the second stopping part 140.

[0141] In a third operation, the first stopping part 130 of the connector 100 is disposed close to the opening 10 of a second accommodation member 1.

[0142] In a fourth operation, after the first stopping part 130 of the connector 100 is inserted into the opening 10 so that the end of the opening 10 of the second accommodation member 1 is positioned between the first stopping part 130 and the second stopping part 140, the open area of the opening 10 is decreased as compared to a cross-sectional area formed by an end of a side surface of the rim of the first stopping part 130 by closing the binding member 11 including the slide fastener, and thus the opening 10 is fixed onto the first stopping part 130.

[0143] In a fifth operation, both the accommodation members 1 and the connector 100 are turned over so that the accommodation member 1 filled with the filler 12 and the accommodation member 1 having an empty interior are positioned in a vertical direction, and the filler 12 moves toward the accommodation member 1 having an empty interior by its own weight.

[0144] When the filler 12 is completely moved, in a sixth operation, the opening 10 of the accommodation member 1 is separated from the connector 100, and to prevent the filler 12 newly filled in the accommodation member 1 from leaking to the outside, the opening 10 of the accommodation member 1 newly filled with the filler 12 should be maintained facing upward in a process of separating the connector 100.

[0145] When the connector 100 is completely separated from the opening 10 of the accommodation member 1 newly filled with the filler 12, the slide fastener formed in the opening 10 of the accommodation member 1 newly filled with the filler 12 is closed, the opening 10 is completely closed, and thus the filler 12 is completely moved.

[0146] In this case, the first and second accommodation members 1 may correspond to any one of the accommodation member 1 having an empty interior and to be filled with the filler 12 and the accommodation member 1 from which the filler 12 is separated and discharged.

[0147] Further, another method of moving the filler 12 using the connector 100 according to the first to fifth embodiments and the optimum embodiment may be performed as follows, and this other method of moving the filler 12 is a combination of the first embodiment and the third embodiment for connection between the connector 100 and the opening 10.

[0148] In particular, this method may be applied to a process of moving the filler 12 filled in the second accommodation member 1 not including the binding member 11 on the opening 10 to the first accommodation member 1 having the binding member 11 including the slide fastener and having an empty interior, or in contrast, a process of moving the filler filled in the first accommodation member 1 having the binding member 11 including the slide fastener to the second accommodation member 1 not including the binding member 11 formed on the opening 10 and having an empty interior.

[0149] In a first operation, the connector 100 is disposed close to the opening 10 of the second accommodation member 1.

[0150] In a second operation, as illustrated in FIG. 3, after the end of the opening 10 of the second accommodation member 1 passes into the hollow 110 from a direction in which the first stopping part 130 is formed, a portion of the second accommodation member 1 at the end of the opening 10 passing through the hollow 110 is turned over to cover an outer surface of the connector 100.

[0151] In a third operation, the binding member 11 that is separated from the opening 10 of the second accommodation member 1 and is separately formed is mounted to surround the outer circumferential surface of the support 120 of the connector 100, and the outer circumferential surface of the support 120 and a portion of the second accommodation member 1 covering the connector 100 are closely fixed to each other by the binding member 11.

[0152] In this case, the binding member 11 of the second accommodation member 1 may be any one selected from a cable tie, a string, and a binder, and may be a different member from the above members as long as the member has a similar function.

[0153] In a fourth operation, the second stopping part 140 of the connector 100 is inserted into the opening 10 so that the end of the opening 10 of the first accommodation member 1 to be filled with the filler 12 and having an empty interior is positioned between the first stopping part 130 and the second stopping part 140.

[0154] Thereafter, the open area of the opening 10 is decreased as compared to the cross-sectional area formed by the end of the side surface of the rim of the second stopping part 140 by closing the binding member 11 including the slide fastener, and thus the opening 10 is fixed onto the second stopping part 140.

[0155] In a fifth operation, both the accommodation members 1 and the connector 100 are turned over so that the second accommodation member 1 and the first accommodation member 1 are positioned in the vertical direction, and the filler 12 moves from the second accommodation member 1 into the first accommodation member 1 by its own weight.

[0156] When the filler 1 is completely moved, a sixth operation is performed, and in the sixth operation, the opening 10 of the accommodation member 1 is separated from the connector 100.

[0157] In this case, when the accommodation member 1 newly filled with the filler 12 is the first accommodation member 1, the opening 10 of the first accommodation member 1 is completely closed by closing the binding member 11 of the first accommodation member 1, and when the accommodation member 1 newly filled with the filler 12 is the second accommodation member 1, the opening 10 of the second accommodation member 1 is closed through a separate binding member 11, and thus leakage of the filler 12 to the outside is prevented.

[0158] Although the embodiments of the present invention have been described with reference to the above content, those skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without changing the technical spirit or essential features thereof.

[0159] Therefore, the embodiments described above should be understood as illustrative and non-limiting in all respects, the scope of the present invention described in the detailed description is defined by the appended claims, and it should be construed that all changes or modifications derived from the meaning and scope of the appended claims and the equivalent concept thereof are included in the scope of the present invention.
