Description

Technical Field

[0001] The present invention relates to a connector connected to an inlet piece for a liquid container, and more particularly, to a connector connected to an inlet piece for a liquid container as follows: in the liquid container, the inlet piece attached to the attachment portion of the liquid container is formed as an insertion type, and the connector connected to the inlet piece is formed as a protrusion type. Background Art

[0002] Unless otherwise indicated herein, what is described in this section is not prior art to the claims in this application and is not admitted to be prior art by inclusion in this section.

[0003] Generally, a liquid container has a predetermined space formed therein for containing a liquid substance, and the liquid container is made of a synthetic resin material. An attachment portion is formed on one side of the liquid container, an inlet piece is sealed and attached to the attachment portion, and a content such as a beverage is injected into or discharged from the space through the inlet piece. Here, the inlet piece may have a shape protruding from the attachment portion of the liquid container by a predetermined length, and may also have a shape in which a cap is placed on one end of the inlet piece and the other end of the inlet piece is inserted into the liquid container.

[0004] Among them, in the case where the liquid container contains liquid beverage, most of the inlet pieces are formed in a protruding type that protrudes outward. When drinking, the protruding portion of the inlet piece is inserted into an insertion type upper connector formed on the upper side of the tubular connecting pipe, and the outer cover of the protruding inlet piece is removed, and the liquid beverage is delivered to the connecting pipe in a mutually connected state.

[0005] Here, if the inlet piece is formed in a protruding type, the protruding inlet piece should be connected to the inserted connector. Since the user must hold the liquid container containing the liquid beverage and hold the inlet piece of the liquid container by hand during the connection, it is inconvenient to use. Figure 1 As shown, in the case where the protruding inlet piece is simply connected to the upper connector formed as an insertion type, there is a risk of contamination when external air or foreign matter is introduced, and if the connection is made by a simple insertion and assembly method, there is also a problem that liquid beverage may leak from the assembly part.

[0030] Hereinafter, the configuration, operation and effect of the connector for a liquid container according to a preferred embodiment will be described with reference to the accompanying drawings. For reference, in the drawings described below, for the sake of convenience and clarity, each component is omitted or schematically shown, and the size of each component does not reflect the actual size. In addition, throughout the specification, the same reference numerals represent the same components, and the reference numerals of the same components in each drawing will be omitted.

[0031] A connector for a liquid container according to an embodiment of the present invention includes: an insertion type inlet piece 10 and a connector 20, the inlet piece 10 is attached to an inlet formed by partially cutting on one side of a liquid container P, the liquid container P having a space formed therein capable of storing liquid, and the inlet piece 10 includes a fitting portion 11, the fitting portion 11 protrudes outward by a predetermined length and has a hollow portion formed therein, the connector 20 includes an insertion portion 210 formed at a front portion and a main body portion 220 formed at a rear portion, the insertion portion 210 is used to be inserted into the hollow portion of the fitting portion 11 of the inlet piece 10, and the main body portion 220 has a hollow portion corresponding to the outer diameter of a tube so that the tube is inserted and liquid is transported through the tube.

[0032] The liquid container P has a space capable of containing various types of liquids. In this configuration, a pair of sheets made of a synthetic resin material are attached along their edges to form an internal space, and the liquid is discharged and transported to the outside through an inlet formed by partially cutting on one side of the attached edge. An inlet piece is attached to the cut inlet. One end of the inlet piece is placed between the pair of sheets and attached to the inlet or sealed by a hot melt method, and the other end protrudes outward by a certain length, and the liquid is discharged and transported to the outside through the fitting portion 11 in which a hollow portion is formed.

[0033] Here, the liquid container P can be formed not only into a shape in which an internal space is defined by a pair of sheets, but also into a container shape having a certain external shape while having a predetermined strength, and the inlet is formed into an insertion type to be inserted into the container so that when used, a protruding type connector can be inserted toward the inlet. Figure 1 Unlike the protruding inlet member shown in FIG. 1 , the connector disclosed in the present invention is configured to be inserted into the interior of the fitting portion 11 having a hollow portion formed therein, such as Figure 2 or Figure 5 Therefore, since a relatively light connector is inserted, the convenience of use can be increased.

[0034] Next, the connector 20 includes: an insertion portion 210 formed at a front portion to be inserted into a hollow portion of the fitting portion 11 of the inlet piece 10, and a main body portion 220 formed at a rear portion, the insertion portion 210 being used to be inserted into a hollow portion of the fitting portion 11 of the inlet piece 10, the main body portion 220 having a hollow portion corresponding to an outer diameter of a tube so that the tube is inserted and liquid is transferred through the tube.

[0035] The connector 20 is roughly divided into an insertion portion 210 and a main body portion 220, the insertion portion 210 being inserted into the hollow portion of the fitting portion 11 of the inlet piece 10, and the tube being inserted into the main body portion 220, forming a grip portion for being gripped by a user. The connector has a hollow portion formed therein from the insertion portion 210 to the main body portion 220, and when the tube is inserted and fitted into the hollow portion, liquid can be transferred from the liquid container P to the tube through the inlet piece 10 and the connector 20. The hollow portion formed in the connector 20 has an inner diameter defined to correspond to the outer diameter of the tube, so that when the tube is inserted into the hollow portion, the tube is gradually inserted and fixed.

[0036] According to a preferred feature of the present invention, the connector 20 may include an inclined surface 211 formed to be inclined to one side at the front end of the insertion portion 210 and a pin hole 213 formed on one side of the inclined surface 211 and communicating with the internal hollow portion.

[0037] The insertion part 210 has an inclined surface 211 inclined to one side to form a sharp front end. The insertion part 210 with the inclined surface 211 has the advantage of being easily inserted into the inlet 10, and has a larger surface area than a horizontal surface, so that more liquid can be transported. Here, the connector may also include a pin hole 213, which is connected to the hollow part on one side of the inclined surface 211 and extends in the longitudinal direction of the insertion part 210. The pin hole 213 is configured to discharge as much residue as possible, which cannot be discharged with the transported liquid when the inlet 10 and the connector 20 are assembled with each other, and remains around the assembly area. When the insertion part 210 is assembled to the assembly part 11, the residue may remain in the gap between the outer periphery of the insertion part 210 and the inner periphery of the assembly part 11, and the pin hole is used as a channel for discharging the remaining residue to the outside. Preferably, the pin hole 213 has a width that increases from the upper side to the lower side, so as to discharge as much residue as possible that accumulates at the lower side.

[0038] According to a preferred feature of the present invention, the connector 20 may also include: a central plate 230 and a pair of flexible fastening wings 231, the central plate 230 is formed along the periphery of the connector 20 to separate the insertion part 210 and the main body part 220 of the connector 20; a pair of flexible fastening wings 231 extend from the central plate 230 toward the insertion part 210.

[0039] According to a preferred feature of the present invention, the inlet piece 10 includes a fixing step 12 formed along the periphery of its assembly portion 11, and the connector 20 may also include a fixing protrusion 232 protruding from the flexible fixing wing 231 toward the insertion portion 210, for fastening the inlet piece 10 and the connector 20 while engaging with the fixing step 12 of the inlet piece 10.

[0040] The central plate 230 is configured to form the fastening wings 231 while distinguishing the relative positions of the insertion portion 210 and the main body portion 220, and defines the geometric configuration of the main body portion 220 together with the rear end plate 240 formed at the rear end of the main body portion 220. The central plate 230 is formed in a disc shape and is formed along the outer circumference of the connector 20, and a pair of fastening wings 231 are formed in a direction from the central plate 230 toward the insertion portion 210. At this time, it is preferred that at least one pair of fastening wings 231 is provided, and the fastening wings 231 are made of a flexible material that can partially expand and contract in the radial direction, thereby being fastened to the fitting portion 11.

[0041] The flexible fastening wing 231 includes a fastening protrusion 232 protruding toward the central axis of the insertion portion 210, and the inlet piece 10 includes a fixing step 12 formed in a ring shape along the outer circumference of the fitting portion 11. Therefore, when the connector 20 is inserted into the inlet piece 10, the fastening protrusion 232 that has approached the fixing step 12 is engaged and fixed to the fixing step 12, thereby preventing the inlet piece from being disengaged in the opposite direction.

[0042] According to a preferred feature of the present invention, the connector may further include an anti-leakage step 215, which extends from the central plate 230 along the periphery of the insertion portion 210 by a predetermined length and contacts the front end of the assembly portion 11 of the inlet piece 10 when the connector 20 is inserted into the inlet piece 10, thereby preventing the liquid delivered from the inlet piece 10 to the connector 20 from leaking to the outside.

[0043] The anti-leakage step 215 may be formed in the shape of a step extending a predetermined length from the central plate 230 along the periphery of the insertion portion 210, and when the connector 20 is inserted into the inlet 10, at the moment when the fastening protrusion 232 is engaged with the fixing step 12, the front end of the anti-leakage step 215 and the front end of the fitting portion 11 are kept in contact with each other, thereby completely blocking the internal space from the outside and preventing liquid leakage. The front end of the fitting portion 11 and the front end of the anti-leakage step 215 may contact each other in the form of mutually horizontal planes, and may be more securely fastened by a method such as block coupling.

[0044] According to a preferred feature of the present invention, the connector 20 may further include an inner peripheral protrusion 221 which protrudes inwardly along the inner periphery of the hollow portion of the connector 20 to prevent the tube from being disengaged and to assemble with one end of the tube when the tube is inserted.

[0045] According to a preferred feature of the present invention, the hollow portion of the connector 20 may have a diameter that decreases from the tip of the insertion portion 210 toward the inner peripheral protrusion 221 and increases after passing the inner peripheral protrusion 221 .

[0046] In the process of inserting the tube into the hollow part of the connector 20, there is a method of inserting and assembling the tube so that the inner diameter of the hollow part and the outer diameter of the tube have corresponding sizes, but there is a possibility that the tube may be detached during use. Therefore, in order to more stably connect the tube to the connector, an inner peripheral protrusion 221 protruding toward the central axis is formed on the inner periphery of the hollow part of the connector 20. Therefore, when the tube is inserted until the inner peripheral protrusion 221, since the front end of the tube passes through the inner peripheral protrusion 221, the tube can no longer be inserted further, and insertion and assembly are performed. At this time, the tube can be prevented from detaching by the inner peripheral protrusion. As another embodiment for preventing the tube from detaching, the hollow part of the connector 20 is formed so that the diameter decreases toward the insertion part 210, especially until the inner peripheral protrusion 221, so that a stronger assembly can be provided when the tube is inserted. The diameter of the tube is formed to increase again after the inner peripheral protrusion, so that the liquid transported from the liquid container P flows in and out at a high rate around the central plate 230.

[0047] Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the embodiments and drawings described and shown in the present disclosure are only the most preferred embodiments and do not represent all the technical spirits of the present invention, and it should be understood that various modifications and equivalents may be made to replace the embodiments when filling this application.
