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 a joint portion of the liquid container has an inwardly recessed type, and the connector coupled to the inlet portion has 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 the present 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 inside 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 by 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 drawn inside.

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

[0005] Here, when the inlet portion is of the protruding type, the protruding inlet portion must be connected to the inserted connector. However, since the user must connect it while lifting the liquid container containing the liquid beverage and gripping the inlet portion of the liquid container, there is inconvenience in use. Further, as shown in FIG. 1, in the form in which the protruding inlet portion is simply connected to the upper end connector in which the inlet portion is recessed, there is a risk of infection while external air and foreign substances flow in. There is also a problem that if it is connected by a simple fitting method, there is a possibility that the liquid beverage may leak at the connection site.

Modes 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 capable of storing liquid is formed, projects a certain length outward, and includes a draw-in type draw-in port portion 10 including a hollow joint portion 11, and a connector 20 having an insertion portion 210 formed at the front end thereof to be inserted into the hollow of the joint portion 11 of the draw-in port portion 10 and a body portion 220 formed at the rear end thereof with a hollow formed to correspond to the outer diameter of a tube into which the tube through which the 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 the liquid to the outside through an inlet cut open on one side of the pasted periphery. A draw-in port 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 the liquid to the outside through a joint portion 11 having a hollow formed inside.

[0024] Here, the liquid container P not only takes the 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 draw-in type that is drawn inward, and a protruding type connector may be inserted toward the inlet during use. Different from the protruding type draw-in port portion shown in FIG. 1, since the connector disclosed in the present invention is configured 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, a connector 20 is included in which an insertion portion 210 to be inserted into the hollow of the coupling portion 11 of the lead-in port portion 10 is formed at the front end, and a body portion 220 having a hollow formed corresponding to the outer diameter of the tube so that the tube through which the liquid is transmitted is inserted is formed at the rear end.

[0026] The connector 20 is mainly composed of an insertion portion 210 inserted into the hollow of the coupling portion 11 of the lead-in port portion 10, and a body portion 220 forming a handle portion for the user to grip with the tube inserted therein. A hollow is formed inside from the insertion portion 210 to the body portion 220. When the tube is inserted and fitted into the hollow, the liquid can be transmitted from the liquid container P to the tube through the lead-in port 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 is gradually fitted and fixed when the tube is inserted into the hollow.

[0027] According to a preferred feature of the present invention, the front end of the insertion portion 210 of the connector 20 has an inclined surface 211 inclined to one side, and is characterized by having a slit 213 provided so as to communicate with the inner hollow from one side of the inclined surface 211.

[0028] The insertion part 210 is configured to have an inclined surface 211 inclined to one side in order to form a sharp front end. The insertion part 210 having the inclined surface 211 has the advantage that it is easy to insert into the draw-in port part 10 and has a larger area than a horizontal plane, so that more liquid can be transmitted. Here, a slit 213 can be further included which extends along the longitudinal direction of the insertion part 210 so as to be communicable with the hollow from one side of the inclined surface 211. The slit 213 is a configuration for discharging residues remaining around the coupling region without being discharged into the liquid transmitted while the draw-in port part 10 and the connector 20 are coupled to each other. There is a possibility that residues remain in the gap between the outer peripheral surface of the insertion part 210 and the inner peripheral surface of the coupling part 11 while the insertion part 210 is fitted into the coupling part 11, and it serves as a passage for discharging the residues remaining in this way to the outside. It is preferable that the slit 213 is wider from the upper part to the lower part so as to discharge the residues accumulating at the lower part to the maximum extent.

[0029] According to a preferred feature of the present invention, a central plate 230 partitioning the insertion part 210 and the body part 220 of the connector 20 is formed along the outer peripheral surface of the connector 20, and further includes a pair of flexible fastening wings 231 extending from the central plate 230 toward the insertion part 210.

[0030] According to a preferred feature of the present invention, a fixed step part 12 formed along the outer peripheral edge of the coupling part 11 of the draw-in port part 10, and a fastening protrusion 232 protruding from the flexible fastening wing 231 of the connector 20 toward the insertion part 210 and fastening the draw-in port part 10 and the connector 20 while being fitted into the fixed step part 12 of the draw-in port part 10 are further included.

[0031] The central plate 230 is configured to form the fastening wings 231 while distinguishing the positions of the insertion part 210 and the body part 220, and partitions the position of the body part 220 together with the rear end plate 240 formed at the rear end of the body part 220. The central plate 230 is disc-shaped, is formed along the outer peripheral 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 part 210. It is preferable that at least a pair of the fastening wings 231 are provided, and they are fastened to the coupling part 11 with flexibility that can be partially expanded and contracted radially.

[0032] The flexible fastening wing 231 has a fastening protrusion 232 protruding in the direction of the central axis of the insertion part 210, and a ring-type fixed step part 12 is formed along the outer peripheral edge of the coupling part 11 of the drawing-in port part 10. When the connector 20 is inserted into the drawing-in port part 10, the fastening protrusion 232 approaching the fixed step part 12 is fastened to the step part while being fitted, and serves to prevent it from detaching in the opposite direction.

[0033] According to a preferred feature of the present invention, it further includes a liquid leakage prevention step part 215 that extends along the outer peripheral surface of the insertion part 210 from the central plate 230 by a predetermined height, and when the connector 20 is fastened to the drawing-in port part 10, it abuts against the front end of the coupling part 11 of the drawing-in port part 10 to prevent the liquid transmitted from the drawing-in port part 10 to the connector 20 from being discharged to the outside.

[0034] The liquid leakage prevention step part 215 takes the form of a step part that extends along the outer peripheral surface of the insertion part 210 from the central plate 230 by a predetermined height. When the connector 20 is fitted into the drawing-in port part 10, at the moment when the aforementioned fastening protrusion 232 is fastened to the fixed step part 12, the front end of the liquid leakage prevention step part 215 and the front end of the coupling part 11 are maintained in contact with each other, and the internal space can be completely blocked from the outside, preventing liquid leakage. The front end of the coupling part 11 and the front end of the liquid leakage prevention step part 215 can be in contact with each other in the form of a horizontal plane, and can also be fastened more reliably by a method such as block coupling.

[0035] According to a preferred feature of the present invention, it further includes an inner peripheral surface protrusion 221 that projects along the hollow inner peripheral surface of the connector 20 and prevents the tube from coming off while being fitted to one end of the tube.

[0036] According to a preferred feature of the present invention, the hollow of the connector 20 has a diameter that becomes smaller from the tip of the insertion portion 210 toward the inner peripheral surface protrusion 221, and becomes larger after passing through the inner peripheral surface protrusion 221.

[0037] In the process of the tube being coupled to the hollow of the connector 20, there is a method in which the inner diameter of the aforementioned hollow and the outer diameter of the tube are configured and fitted to correspond to each other, but this may become detached during use. Thus, in order for the tube to be more securely coupled, when the tube is inserted from the inner peripheral surface of the hollow of the connector 20 toward the inner peripheral surface protrusion 221 projecting in the central axis direction, the front end of the tube is fitted without being inserted any further while passing through the inner peripheral surface protrusion 221, and the inner peripheral surface protrusion 221 can prevent the tube from coming out. As another embodiment for preventing the tube from coming off, the hollow of the connector 20 is configured to have a smaller diameter toward the insertion portion 210, particularly up to the inner peripheral surface protrusion 221, so that it can be more strongly fitted when the tube is inserted, and is configured to have a larger diameter thereafter, and the liquid transmitted from the liquid container P rapidly flows in and out around the central plate 230.

[0038] The preferred embodiments of the present invention have been described above with reference to the accompanying drawings. However, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modifications that can replace them at the time of this application. Accordingly, the embodiments described above should be understood to be exemplary in all respects and not limiting. The scope of the present invention is indicated by the claims described below, rather than the detailed description. All changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included within the scope of the present invention.
