Description

Technical Field

[0001] The present invention relates to a connector coupled to an inlet portion for a liquid container. More specifically, the present invention relates to a connector coupled to an inlet portion for a liquid container, wherein the inlet portion formed at the joint portion of the liquid container is of a retracted type, and the connector coupled to the inlet portion is of a protruding type.

Background Art

[0002] Unless otherwise indicated in this specification, the content described in this section is not prior art with respect to the claims of this application, and even if included in this section, is not recognized as prior art.

[0003] Generally, a liquid container is made of a synthetic resin material having a predetermined space formed therein so as to accommodate a liquid substance. A joint portion is formed on one side of the liquid container, and an inlet portion is sealed and joined to the joint portion, and the contents are injected or discharged through the inlet portion. Here, the inlet portion may have a form protruding a certain length from the joint portion of the liquid container, or may have a form in which a cap is put on in a form retracted inside.

[0004] Among them, in the case of a liquid container containing a liquid beverage, most of the inlet portions are of a protruding type protruding outward, and in a state where the outer cap of the protruding type inlet portion is removed, it is fitted into an upper end connector of a retracted type formed on an upper side of a tubular connecting pipe and interconnected, and the liquid beverage is transmitted to the connecting pipe.

[0005] Here, if the inlet portion is of the protruding type, the protruding inlet portion must be connected to the retracted connector, but the user must lift the liquid container containing the liquid beverage and grasp the inlet portion of the liquid container while connecting, which is inconvenient in terms of use. Also, as shown in Figure 1, in a configuration where the protruding inlet portion is simply connected to the upper end connector formed by the retraction, there is a risk of infection as outside air and foreign matter enter, and if connected by a simple mating method, there is also the problem that the liquid beverage may leak at the connection point.

Mode for Carrying Out the Invention

[0021] Hereinafter, with reference to the accompanying drawings, the configuration, operation, and effects of the liquid container connector according to a preferred embodiment will be described. For reference, in the following figures, each component is omitted or schematically illustrated for convenience and clarity, and the size of each component does not reflect the actual size. Also, throughout the specification, the same reference numerals refer to the same components, and in each individual drawing, the reference numerals for the same configuration are omitted.

[0022] A liquid container connector according to an embodiment of the present invention is adhesively formed at an inlet cut open from one side of a liquid container P in which a space for storing liquid is formed inside, projects a certain length outward, and includes a retractable inlet portion 10 including a hollow joint portion 11, and a connector 20 having an insertion portion 210 formed at the front end thereof inserted into the hollow of the joint portion 11 of the inlet portion 10 and a body portion 220 formed at the rear end thereof having a hollow formed corresponding to the outer diameter of a tube so that the tube through which liquid is transmitted is inserted.

[0023] The liquid container P has a configuration having a space capable of accommodating various forms of liquid, is formed with a space inside by being pasted along the periphery of a pair of sheets made of a synthetic resin material, and transmits liquid to the outside through an inlet cut open on one side of the pasted periphery. A retractable inlet portion is adhesively formed at the cut open inlet, but is interposed between the pair of sheets and sealed by an attachment or heat fusion method or the like, projects a certain length outward, and transmits liquid to the outside through a joint portion 11 having a hollow formed inside.

[0024] Here, the liquid container P not only takes a form in which a pair of sheets form an internal space, but also has a container shape forming an outer shape while having a predetermined strength, and its inlet is of a retractable type that is drawn inward, and a protruding connector may be inserted toward the inlet during use. Different from the protruding inlet portion shown in FIG. 1, by configuring the connector disclosed in the present invention to be inserted into the hollow joint portion 11 as shown in FIG. 2 or FIG. 5, a relatively light connector may be inserted, so that the usability can be increased.

[0025] Next, the connector 20 includes an insertion portion 210 formed at its front end, which is inserted into the hollow of the coupling portion 11 of the inlet portion 10, and a body portion 220 formed at its rear end, which has a hollow corresponding to the outer diameter of the tube into which a tube through which liquid is transmitted is inserted.

[0026] The connector 20 is broadly composed of an insertion portion 210 that is inserted into the hollow of the coupling portion 11 of the inlet portion 10, and a body portion 220 into which a tube is inserted and which forms a handle portion for the user to grasp. A hollow is formed inside from the insertion portion 210 to the body portion 220, and when a tube is inserted into the hollow and fitted, liquid can be transmitted from the liquid container P to the tube via the inlet portion 10 and the connector 20. The inner diameter of the hollow formed in the connector 20 is formed to correspond to the outer diameter of the tube, and when the tube is inserted into the hollow, it is gradually fitted and fixed.

[0027] According to preferred features of the present invention, the front end of the insertion portion 210 of the connector 20 has an inclined surface 211 that is tilted to one side, and a slit 213 that is provided to communicate with the internal hollow from one side of the inclined surface 211.

[0028] The insertion portion 210 is configured to have an inclined surface 211 that is tilted to one side in order to form a sharp front end. The insertion portion 210 having the inclined surface 211 has the advantage of being easy to insert into the inlet portion 10 and having a larger surface area than a horizontal surface, thus allowing more liquid to be transmitted. Here, a slit 213 may be further provided extending along the longitudinal direction of the insertion portion 210 so as to communicate with the hollow from one side of the inclined surface 211. The slit 213 is configured to maximize the discharge of residue that remains around the coupling area without being discharged into the liquid transmitted while the inlet portion 10 and the connector 20 are coupled together. There is a possibility that residue may remain in the gap between the outer circumferential surface of the insertion portion 210 and the inner circumferential surface of the coupling portion 11 while the insertion portion 210 is fitted into the coupling portion 11, and the slit 213 serves as a passage for discharging such remaining residue to the outside. It is preferable that the width of the slit 213 increases from the top to the bottom so as to maximize the discharge of residue that accumulates at the bottom.

[0029] A preferred feature of the present invention is that a central plate 230 separating the insertion portion 210 and the body portion 220 of the connector 20 is formed along the outer circumferential surface of the connector 20, and the invention further includes a pair of flexible fastening wings 231 extending from the central plate 230 toward the insertion portion 210.

[0030] According to preferred features of the present invention, the present invention further includes a fixed step portion 12 formed along the outer peripheral edge of the connecting portion 11 of the retraction port 10, and a fastening projection 232 that protrudes from the flexible fastening wing 231 of the connector 20 toward the insertion portion 210 and fastens the retraction port 10 and the connector 20 while being fitted into the fixed step portion 12 of the retraction port 10.

[0031] The central plate 230 is configured to form the fastening wings 231 while separating the positions of the insertion portion 210 and the fuselage portion 220, and together with the rear end plate 240 formed at the rear end of the fuselage portion 220, it defines the position of the fuselage portion 220. The central plate 230 is disc-shaped and formed along the outer edge of the connector 20, and a pair of fastening wings 231 are formed in the direction from the central plate 230 toward the insertion portion 210. Preferably, there are at least one pair of fastening wings 231, and they are fastened to the coupling portion 11 with flexibility that allows them to be partially expanded and contracted radially.

[0032] The flexible fastening wing 231 has fastening projections 232 projecting in the direction of the central axis of the insertion portion 210, and a ring-type fixed step portion 12 is formed along the outer edge of the connecting portion 11 of the retraction port 10. When the connector 20 is inserted into the retraction port 10, the fastening projections 232 approach the fixed step portion 12 and are fitted into the step portion, fastening it and preventing it from coming loose in the opposite direction.

[0033] A preferred feature of the present invention is that it further includes a leak prevention step 215 which extends from the central plate 230 along the outer circumferential surface of the insertion portion 210 by a predetermined height and contacts the front end of the coupling portion 11 of the intake portion 10 while the connector 20 is fastened to the intake portion 10, thereby preventing the liquid transmitted from the intake portion 10 to the connector 20 from being discharged to the outside.

[0034] The leak-preventing stepped portion 215 takes the form of a stepped portion that extends from the central plate 230 along the outer circumferential surface of the insertion portion 210 by a predetermined height. When the connector 20 is fitted into the inlet portion 10, at the moment the aforementioned fastening projection 232 is fastened to the fixed stepped portion 12, the front end of the leak-preventing stepped portion 215 and the front end of the coupling portion 11 are maintained in contact with each other, completely sealing the internal space from the outside and preventing leakage. The front end of the coupling portion 11 and the front end of the leak-preventing stepped portion 215 can be in contact with each other in a horizontal plane, and can be fastened more securely by methods such as block coupling.

[0035] A preferred feature of the present invention is that it further includes an inner circumferential projection 221 which is provided along the hollow inner circumferential surface of the connector 20 and is fitted onto one end of the tube to prevent the tube from coming off.

[0036] According to preferred features of the present invention, the hollow of the connector 20 is characterized in that its diameter decreases from the tip of the insertion portion 210 toward the inner circumferential projection 221, and increases after passing the inner circumferential projection 221.

[0037] In the process of coupling the tube into the hollow of the connector 20, there is a method in which the inner diameter of the hollow and the outer diameter of the tube are configured to correspond to each other and fit together, but this may cause the tube to detach during use.Therefore, in order to ensure that the tube is coupled more securely, when the tube is inserted up to the inner circumferential projection 221 that protrudes from the inner circumferential surface of the hollow of the connector 20 toward the central axis, the front end of the tube passes through the inner circumferential projection 221 and is fitted without being inserted further, but the inner circumferential projection 221 prevents the tube from coming out.As another embodiment to prevent the tube from coming out, the hollow of the connector 20 is configured so that the diameter decreases toward the insertion portion 210, especially up to the inner circumferential projection 221, so that the tube fits more tightly when inserted, and thereafter the diameter increases again, so that the liquid transmitted from the liquid container P flows in and out rapidly around the central plate 230.
