Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an environmentally friendly spout cap,

The present invention relates to an environmentally friendly cap which is mounted on an outlet of a liquid container and is made usable repeatedly, and an environmentally friendly liquid container having the same.

A liquid container is a container for holding various kinds of liquids and the like. The liquid container is provided with a discharge port to discharge the liquid contained therein to the discharge port.

A cap which can be opened and closed is attached to the outlet of the liquid container. Particularly, a liquid container for containing lubricating oil, cooking oil, or the like is generally equipped with a spout cap having an anti-falsification and sealing function.

The spout cap is a spout of the liquid container and can be pushed or pulled out, and is formed in a structure capable of sealing and unsealing.

1 and 2 are a perspective view and a cross-sectional view of an example of a conventional spout cap.

As shown in these figures, the conventional spout cap 20 comprises an inner stopper 21, an outer stopper 22 and a protective cap 23.

The inner stopper 21 is formed to be foldable so as to be seated on the discharge port 11 of the liquid container 10. The inner cap 21 is provided with a cutable inner cap 21a. When the inner cap 21a is removed, the removed portion forms the discharge hole 21b of the liquid container 10. [

The outer stopper 22 is detachably coupled to the inner stopper 21 and the discharge hole 21b of the inner stopper 21 is opened and closed by the outer stopper 22. [ The outer stopper 22 is formed with a knob 22a for opening and closing the outer stopper 22 by turning it.

The protective cap 23 is tightly coupled to the outlet 11 of the liquid container 10 and the outer cap 22 is concealed by the protective cap 23. A hook 23a is formed in the protective cap 23 and a hooked end 12 is formed in the liquid container 10 so that the hook 23a of the protective cap 23 is caught and tightly coupled.

The protective cap 23 is formed with a separating stopper portion 23a for concealing the handle 22a of the outer stopper 22. The separation cap 23a is detachably connected to the inner circumferential surface of the protective cap 23.

The conventional spout cap 20 as described above is configured such that when the user removes the separating lid portion 23a of the protective cap 23 and turns it while grasping the handle 22a of the outer lid 22, Is separated from the inner stopper 21.

Then, when the inner cap 21a of the inner cap 21 is exposed and the inner cap 21a exposed by the user is pulled and removed, the vent hole 21b of the inner cap 21 is opened.

Then, the user tilts the liquid container 10 and pours the contents contained in the liquid container 10 into the discharge hole 21b of the inner stopper 21 to use as necessary.

After discharging all the contents contained in the accommodation space S of the liquid container 10, the liquid container 10 is placed in a waste oil collecting container (hereinafter abbreviated as waste oil container) with the spout cap 20 removed. Can be recycled.

Here, when the spout cap 20 is removed, the protective cap 23 may be separated from the liquid container 10, and the inner cap 21 may be removed together with the outer cap 22. However, the conventional protective cap 23 is structured so as to be hardly coupled to the latching end 12 of the liquid container 10 to separate the inner stopper 21. Accordingly, the user cuts off the middle portion of the inner stopper 21 and collects the waste oil in a state in which the discharge port 11 of the liquid container 10 is secured.

However, in the conventional spout cap, the outer cap 22 for opening and closing the outlet 11 of the liquid container 10 is attached to and detached from the inner cap 21, but the inner cap 21 is cut off and completely removed The original outer cap 22 can not be used. Therefore, the user frequently clogs the discharge port 11 using a paper cup, plastic, or a temporary stopper that does not meet the standard so that contents contained in the liquid container 10 are not leaked. However, when the outlet 11 of the liquid container 10 is closed with a paper cup, a plastic or a temporary stopper that does not meet the specifications, a gap may be generated between the temporary stopper and the discharge port 11, There is a possibility that the temporary stopper is detached and the contents are poured in the process of moving the liquid container 10 or moving the liquid container 10. In addition, there is a possibility that the foreign matter may flow into the liquid container 10 and contaminate the contents.

Further, in the conventional spout cap 20, when the inner cap 21 is cut and removed, the inner cap 21 can not be reused. Therefore, even if it is necessary to use the inner stopper, the inner stopper 21 which has already been removed can not be used, which causes inconveniences in use and wastes resources.

It is an object of the present invention to provide an environmentally friendly spout cap capable of opening and closing an outlet regardless of whether an inner cap is mounted or not, and an environmentally friendly liquid container having the spout cap.

It is another object of the present invention to provide an environmentally friendly spout cap capable of firmly closing an opened outlet and an environmentally friendly liquid container having the spout cap.

The fixing portion 211 may include a first fixing protrusion 211a and a second fixing protrusion 211b. A seating surface 211c is formed between the first fixing protrusion 211a and the second fixing protrusion 211b so that the upper surface of the common locking end 114a of the liquid container 100 is seated. The first fixing protrusions 211a and the second fixing protrusions 211b are formed at predetermined intervals in the radial direction and are positioned on the inner side and the outer side with respect to the common locking end 114a of the liquid container 100. [

The first fixing protrusion 211a is located inside the second fixing protrusion 211b and the second fixing protrusion 211b is extended from the first fixing protrusion 211a and is located outside the first fixing protrusion 211a As shown in FIG. The first fixing protrusion 211a is inserted and fixed in the inner periphery of the discharge port 114 of the liquid container 100 and the second fixing protrusion 211b is inserted and fixed to the outer periphery of the discharge port 114 of the liquid container 100 .

The first fixing protrusions 211a and the second fixing protrusions 211b may be formed in a ring shape and the first fixing protrusions 211a may be formed thin so as to have a greater elastic force than the second fixing protrusions 211b . The inner stopper 210 can be elastically inserted into the discharge port 114 of the liquid container 100 and can be brought into close contact with the inner peripheral surface of the discharge port 114. [

On the other hand, the second fixing protrusion 211b may be formed to be relatively thicker than the first fixing protrusion 211a, so that the inner cap 210 can be fixed so as not to be easily detached. Thus, it is possible to prevent the inner cap 210 from being removed when the contents of the liquid container 100 are discharged while the inner cap 210 is mounted.

The second fixing protrusion 211b may be inserted into the outer periphery of the discharge port 114 of the liquid container 100 and may be coupled to the common holding end 114a of the liquid container 100. [ The first hook protrusion 211d may be formed on the inner surface of the lower end of the second fixing protrusion 211b so as to be hooked to the common locking end 114a of the liquid container 100. [

The first body part 212 may extend in the middle than the lower end of the first fixing protrusion 211a and may have an elastic force when the end of the first fixing protrusion 211a is press- have.

The first body part 212 may be formed to be thinner than the second body part 213 so that the first body part 212 can be freely bent when the user pulls the inner stopper 210 by pulling it or pushing it in.

The second body part 213 may extend from one end of the folded part 214 and may be formed to protrude in a direction opposite to the accommodation space S by folding.

The inner body of the second body part 213 is provided with a cutable inner cap 215. When the inner cap 215 is removed by the user, the removed part forms an outlet 114 of the liquid container 100 do.

A first thread 213a is formed on an outer circumferential surface of the second body 213 so as to be threadedly engaged with the outer cap 220. The user can use the first cap 213 of the outer cap 220, And the second threaded portion is screwed to close the discharge hole 210a of the second body portion 213. [

The folded portion 214 may extend from the lower end of the first body portion 212 to connect the first body portion 212 and the second body portion 213. The folded portion 214 may be formed to be elastically formed so as to be folded and stretched when the inner stopper 210 is pulled in or pulled out.

The folded portion 214 may be formed in a U-shape as shown in FIG. 5, but may be formed at least one time so as to be smoothly folded.

5 to 7, the outer stopper 220 can be detachably attached to and detached from the inner stopper 210, and can be detachably attached to the liquid container 100 when the inner stopper 210 is removed . The outer stopper 220 not only serves to open and close the discharge hole of the inner stopper 210 but also serves to open and close the discharge hole 114 of the liquid container 100 when the inner stopper 210 is removed.

More specifically, the outer stopper 220 may be formed in a flange shape such that a cover portion 221 covering the discharge hole 210a forming the open end of the inner stopper 210 is formed. The cover portion 221 may be formed such that its outer diameter D1 is at least equal to or greater than the area of the discharge hole 210a but the outer stopper 220 must be capable of opening and closing the discharge port 114 of the liquid container 100 It may be preferable to be formed not only to be larger than the diameter of the discharge hole 210a but also to have an outer diameter larger than the outer diameter D2 of the common holding end 114a.

A first cap portion 222 for opening and closing the discharge hole 210a of the inner stopper 210 is formed at the center of the bottom surface of the cover portion 221 and a discharge port The second cap part 223 may be formed.

The first cap part 222 has a height overlapping the end of the second body part 213 and is screwed to the first thread part 213a of the second body part 213 on the inner circumferential surface of the first cap part 222 A second screw thread 222a may be formed.

The first cap portion 222 has an inner diameter capable of receiving the end portion of the second body portion 213 of the inner stopper 210 and can be formed to have an outer diameter smaller than the inner diameter of the discharge port 114 of the liquid container 100 have. When the user removes the inner stopper 210 and directly opens and closes the outlet 114 of the liquid container 100 with the outer stopper 220, the first cap portion 222 is moved to the outlet 114 of the liquid container 100, .

A first sealing protrusion 224 may be formed on the inside of the first cap 222 at a predetermined distance from the first cap 222. The first sealing protrusion 224 may be formed at an interval enough to be in close contact with the inner circumferential surface of the second body 213 from the first cap 222 to improve the sealing effect.

The first sealing portion 224 may be formed to have a length shorter than or equal to the length of the first cap portion 222 so that the first sealing portion 224 is advantageous from the processing side and does not interfere with the inner cap 215 May be preferably formed. In addition, although the first sealing protrusion 224 can be prevented from being deformed as it is thicker, it may be thinner or thinner than the first cap portion 222.

The second cap portion 223 may be integrally formed to extend downward from the outer periphery of the cover portion 221 and protrude by a predetermined height.

The second hook protrusion 223a may be formed on the inner surface of the lower end of the second cap portion 223 so that the second cap portion 223 is hooked to the common holding end 114a of the liquid container 100. [ The second hook protrusion 223a is hooked to the common hook end 114a in the same manner as the first hook protrusion 211d so that the inner diameters d1 and d2 of the second hook protrusion 223a and the first hook protrusion 211d, And the shape can be formed almost the same.

Although not shown in the drawing, threads may be formed so that hook protrusions are not formed on the second cap portion 223 but are screwed to the common holding end 114a. In this case, a thread may be formed also around the common holding end 114a.

The second cap portion 223 is formed to have a height such that the second screw portion of the first cap portion 222 does not interfere with the first screw portion 213a of the second body portion 213 Lt; / RTI > The center portion of the cover portion 221 may be recessed by a predetermined depth so that the lower end of the second cap portion 223 is positioned higher than the center portion of the cover portion 221. [ The cover portion 221 is formed to have the same thickness and the central portion is formed to be low so that the end portion of the second body portion 213 is in close contact with the bottom surface of the cover portion 221 while lowering the height of the first cap portion 222 . In this case, the interface 225 between the first cap part 222 and the second cap part 223 is inclined so that it is advantageous in terms of processing, and foreign matter accumulation on the central part of the cover part 221 can be reduced.

A second sealing protrusion 226 protruding downward at a predetermined distance from the inside of the second cap portion 223 and closely contacting the inner circumferential surface of the common retaining end 114a of the liquid container 100 may be formed. When the outlet 114 of the liquid container 100 is sealed with the outer cap 220, the second cap portion 223 of the outer cap 220 is formed around the outlet 114 of the liquid container 100 And the second sealing protrusion 226 can be brought into close contact with the inner circumferential surface of the common engaging end 114a. Accordingly, the second cap portion 223 and the second sealing protrusion portion 226 form a kind of labyrinth seal, so that it is possible to prevent the contents from flowing out or from entering foreign matter even if the internal stopper 210 is removed.

The second sealing protrusion 226 may be formed to be lower than the second cap protrusion 223 in the same manner as the first sealing protrusion 224 because it is possible to avoid interference with the second hook protrusion 223a.

As shown in FIGS. 6 and 7, the outer cap 220 may be provided with means for simplifying operation of the spout cap 200 and for opening and closing the spout cap 200 more easily. The means may be embodied by a plurality of elements formed in the outer cap 220.

The cover part 221 of the outer stopper 220 is formed to receive the inner stopper 210 and the outer circumference of the cover part 221 is formed with a coupling protrusion 228 radially protruding from the handle 227, .

More specifically, the handle 227 is extended from the coupling protrusion 228 so as to form a through hole h between the handle 227 and the cover portion 221, so as to surround the outer periphery of the outer cap 220 . That is, the handle 227 is structured not to be cut from the cover 221 of the outer stopper 220 but to be spaced apart from the cover 221 of the outer stopper 220.

The connection protrusions 228 and the grips 227 may be formed in plural numbers, respectively. The plurality of connection protrusions 228 protrude in opposite directions from each other on the plane, and the plurality of handles 227 may be formed on both the left and right sides so as to be symmetrical with respect to each other about the connection protrusions 228. The user bends the plurality of knobs 227 in the direction toward the connection protrusions 228 and then grasps the knobs 227 and then rotates the outer stopper 220 to rotate the outer stopper 220 from the inner stopper 210 It is manipulated to attach and detach.

The handle 227 may be formed with a bent groove 227a, which is recessed from one surface of the handle 227, respectively. The bending groove 227a may be disposed adjacent to the coupling protrusion 228 and may be formed to be parallel to the coupling protrusion 228. [ The knob 227 can be more easily bent in the direction toward the coupling protrusion 228 by the bent groove 227a.

In addition, a grip protrusion 227b may be formed on the outer circumferential surface of the handle 227 so that the user can easily grip the handle 227. The grip protrusion 227b may be formed on the inner circumferential surface of the handle 227. Since there is no separate component on the outer circumference of the outer stopper 220, it is convenient to form the grip protrusion 227b on the outer circumferential surface of the grip 227 .

The process of separating the cap from the environmentally friendly cap and the liquid container having the same according to the present invention will be described as follows.

8A and 8B are operation diagrams showing a process of opening an inner stopper in FIG. Referring to these drawings, the user grasps the gripping protrusion of the handle 227, lifts both grips 227, and bends so that both grips 227 are gathered. At this time, the handle 227 is connected to the circumference of the outer stopper 220 by the connection protrusion 228, and the bending groove 227a is formed at the connection portion thereof, so that the handle 227 can be easily bent.

Next, the user pulls the handle 227 to pull out the second body portion 213 of the inner stopper 210 to the outside.

The user then removes the inner cap 210 from the inner cap 210 by turning the outer cap 220 after the inner cap 210 is drawn out and removes the inner cap 215 of the inner cap 210, To the outside.

Next, when the contents of the liquid container 100 remain, the user rotates the second cap part 223 of the outer cap 220 to the second body part 213 of the inner cap 210 and then reverses the opening direction. The second thread 222a of the outer stopper 220 is engaged and engaged with the first thread 213a of the inner stopper 210. [

When the outer stopper 220 is pushed toward the inner space of the housing 110, the first body portion 212 of the inner stopper 210 is folded and the second body portion 213 is pushed into the discharge port 114 do.

On the other hand, after discharging all the contents from the liquid container 100, the liquid container 100 can be recycled as a waste container. It is convenient to remove the inner stopper 210 in order to recycle the liquid container 100 as a waste oil container.

The user removes the first stopper 211d of the inner stopper 210 from the common stopping end 114a of the liquid container 100 and then removes the inner stopper 210 from the liquid container 100 . Then, the discharge port 114 of the liquid container 100 is completely opened, so that the liquid such as the waste oil can be easily contained in the containing space S of the liquid container 100.

The first stopper protrusion 211a provided on the outer periphery of the inner stopper 210 is inserted into the discharge port 114 of the liquid container 100 and the second stopper protrusion 211b is inserted into the discharge port 114 The first hook protrusion 211d can be relatively easily separated from the common hooking end 114a because the first hook protrusion 211d is not doubly fixed by the other member.

Meanwhile, the outlet 114 of the liquid container 100 can be opened and closed by using the outer stopper 220 in a state where the inner stopper 210 is removed.

FIG. 9 is a cross-sectional view showing the state where the outer stopper is coupled to the liquid container with the inner stopper removed in FIG. When the inner cap 210 is removed, the first cap portion 222 of the outer cap 220 is inserted into the outlet 114 of the liquid container 100, while the second cap portion 223 is inserted into the liquid And is inserted into the common engaging end 114a protruding around the discharge port 114 of the container 100. [ At this time, the second hook protrusion formed at the lower end of the second cap portion 223 is hooked to the common stopping end 114a, so that the outer stopper 220 retains the coupling strength to such an extent that it can not be detached by itself.

Here, the second sealing protrusion provided on the inner side of the second cap portion 223 is in contact with the inner peripheral surface of the discharge port 114 of the liquid container 100. Accordingly, the second sealing portion 226 and the second cap portion 223 are in contact with the inner circumferential surface and the outer circumferential surface of the discharge port 114 with the discharge port 114 interposed therebetween, so that the sealing force can be increased.

Thus, even when the inner stopper 210 is removed, the outer stopper 220 is used to tightly close the outlet 114 of the liquid container 100, thereby preventing the contents inside the liquid container 100 from flowing out to the outside It is possible to effectively prevent foreign matter from entering from the outside.
