Description

Mixing container with dropper

The present invention relates to a mixing container that can be used by using a dropper after mixing two different kinds of substances inside the container.

A mixing container is used that allows two different types of contents to be separated and stored in one container and then mixed when used. For example, when the contents are cosmetics, mixing containers that can be mixed and used are manufactured and sold after each storage of a gel-shaped base and powder so as not to be mixed. In such a mixing container, if two different types of contents are mixed before use, the contents may deteriorate or their performance may deteriorate during a long period of circulation, and a synergy effect in function can be expected by mixing two or more types of contents. It is mainly used when possible.

Meanwhile, in the case of functional cosmetics such as essences, since the contents are expensive, a container capable of discharging the correct amount of contents is used. One of the discharging means capable of discharging the contents quantitatively is a dropper. The dropper is formed with a pocket made of rubber or silicone at the end of a long glass tube, and has the advantage of being able to dispense the contents drop by drop after accurately discharging the contents.

As a conventional mixing container equipped with a dropper, there is a Republic of Korea Utility Model Registration No. 0487631. In the mixing container disclosed in the prior art document, the contents are filled into the inside of the dropper and the inlet is closed using a cap. In addition, when the dropper is removed from the container body during the first use, the cap is separated so that the contents inside the dropper are discharged.

The conventional mixing container as described above has a problem in that it is difficult to insert the dropper to which the cap is attached into the container. In addition, in the conventional mixing container, the cap separated from the dropper is not removed and remains inside the container body as it is, so it is inconvenient to use and causes an adverse effect in terms of aesthetics.

Accordingly, the present invention was derived to solve the above-described problems, and the present invention is to provide a dropper-type mixing container that is simple to manufacture and convenient to use.

Other objects of the present invention will become more apparent through the examples described below.

1 is a cross-sectional view illustrating a mixing container 100 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view illustrating a dropper 190 used in the mixing container 100 illustrated in FIG. 1. And Figure 3 is a cross-sectional view illustrating the first body 110, the second body 130, the piston 160, and the lower cap 180.

1 to 3, the mixing container 100 according to the present embodiment is filled with the first contents 102 and the second contents 104 unmixed therein. And the mixing container 100 may include a dropper 190 as a means for discharging the contents. In the process of coupling the dropper 190 to the upper part of the mixing container 100 illustrated in FIG. 1, the piston 160 It is characterized in that the first content 102 and the second content 104 can be mixed by moving downwardly pressed by the dropper 190.

The mixing container 100 according to an embodiment of the present invention includes a first body 110, a second body 130, a piston 160, and a lower cap 180. In addition, the mixing container 100 according to the present embodiment may be provided with a dropper 190 as a means for discharging the contents.

The first body 110 is a hollow container having a circular cross section and has an inlet 114 formed thereon. And there is a thread 116 is formed around the inlet 114, the eyedropper cap 194 is screwed to the thread.

A guide member 108 is press-fitted into the inlet 114. The guide member 108 has a guide hole 106, and the nozzle 198 of the dropper 190 is inserted into the first body 110 through the guide hole 106. In addition, since the diameter of the guide hole 106 is almost the same as the outer diameter of the nozzle 198, the contents (not shown) adsorbed to the outer circumferential surface of the nozzle 198 are guide members in the process of passing through the guide hole 106. Can be removed by (108).

A first internal space 120 is formed inside the first body 110. The first contents 102 are filled in the first inner space 120. The first inner space 120 is formed by a first circumferential surface 118, a head inclined surface 134 of the insertion head 132, and a center protrusion 136 of the insertion head 132. The open lower part of the center protrusion 136 may be closed while contacting the piston 160.

The lower end of the first body 110 has an open structure, through which the insertion head 132 of the second body 130 can be inserted into the first body 110.

A coupling end 124 is formed at the lower end of the first body 110. The coupling end 124 is inserted into the coupling groove 142 formed around the second body 130, whereby the first body 110 and the second body 130 are coupled to each other.

The second body 130 includes an insertion head 132 inserted into the lower end of the first body 110 and a lower body 146 exposed to the outside. In addition, the piston 160 is movably inserted into the second body 130 and the lower cap 180 is coupled to the lower end.

The insertion head 132 has a hollow cylindrical shape and a head inclined surface 134 is formed on the upper surface thereof. A center protrusion 136 is formed in the center of the head inclined surface 134. In addition, the head inclined surface 134 is formed to be inclined downward in the direction of the center protrusion 136, whereby the first contents 102 filled on the upper part of the head inclined surface 134 can be easily introduced in the direction of the center protrusion 136. I can.

The center protrusion 136 corresponds to a hollow cylinder protruding downward from the center of the head inclined surface 134. Both the upper and lower ends of the center protrusion 136 have through holes 138 formed therein to have an open structure. In addition, referring to Figure 1, the outer diameter of the center protrusion 136, when the center protrusion 136 is inserted into the center insertion groove 166 of the piston 160, the outer diameter is on the inner peripheral surface of the center insertion groove 166 It can be formed to be able to contact. Due to this, the first content 102 inside the center protrusion 136 does not flow into the second inner space 172.

The length of the center protrusion 136 corresponds to the distance between the head inclined surface 134 and the piston inclined surface 162. Therefore, when the length of the center protrusion 136 is large, the distance between the head inclined surface 134 and the piston inclined surface 162 is large, and the volume of the second internal space 172 increases. Conversely, when the length of the center protrusion 136 is small, the volume of the second inner space 172 decreases. Accordingly, the length of the center protrusion 136 can be determined in consideration of the amount of the second contents 104 filled in the mixing container 100.

The diameter of the through hole 138 formed in the center protrusion 136 may be larger than the outer diameter of the nozzle 198 of the dropper 190. Accordingly, the nozzle 198 can easily pass through the center protrusion 136 and press the piston 160 downward.

The insertion head 132 has a head circumferential surface 140. The head circumferential surface 140 has a structure extending downward from the edge of the head inclined surface 134, and the lower end is continuously connected to the lower body 146. The outer circumferential surface of the head circumferential surface 140 is in contact with the inner circumferential surface of the first body 110, thereby preventing leakage of the first contents 102.

The lower body 146 has a larger outer diameter than the insertion head 132 and is continuously connected to the lower end of the first body 110. Since the diameter of the lower body 146 is the same as the diameter of the first body 110, it is possible to form the outer body of the continuous mixing container 100 without forming a step.

The lower cap 180 is coupled to the lower end of the lower body 146.

A coupling groove 142 is formed in the connection portion between the insertion head 132 and the lower body 146 by the difference in outer diameter between the two. The coupling groove 142 is a groove having a certain depth and formed over the entire circumference of the second body 130. And a locking groove 144 is formed on the inner peripheral surface of the coupling groove 142. The coupling end portion 124 of the first body 110 is inserted into the coupling groove 142, and the protrusion 126 formed around the coupling end portion 124 is inserted into the locking groove 144, so that the first body 110 ) And the coupling of the second body 130 is completed.

The piston 160 is located inside the insertion head 132 of the second body 130 and forms a second internal space 172 in which the second contents 104 are filled together with the insertion head 132. In addition, the piston 160 is pressed by the user and moves downward, whereby the first inner space 120 and the second inner space 172 communicate with each other.

The piston 160 has a circular piston inclined surface 162. A center insertion groove 166 is formed in the center of the piston inclined surface 162, and a piston rib 164 is formed at the edge. The piston inclined surface 162 is formed to be inclined downward in the direction of the center insertion groove 166, and thus, the contents can be concentrated in the direction of the center insertion groove 166.

The piston inclined surface 162 corresponds to one of the lower boundary surfaces of the second inner space 172. That is, the upper interface of the second inner space 172 is the insertion head 132 is the head inclined surface 134, the lower interface is the piston inclined surface 162 and the center insertion groove 166, and the interface between them is the insertion head It corresponds to the inner peripheral surface of (132).

The piston rib 164 is formed to protrude vertically upward around the end of the inclined piston 162. The piston rib 164 moves while in close contact with the inner circumferential surface of the insertion head 132, so that the contents do not flow out to the lower cap 180.

The center insertion groove 166 is a groove formed in the center of the piston inclined surface 162 and has a hollow cylindrical shape. The upper surface of the center insertion groove 166 is open and the lower surface is closed. In addition, a piston protrusion 168 is extended on the lower surface of the center insertion groove 166. When the piston 160 does not descend, the center protrusion 136 of the second main body 130 is inserted into the center insertion groove 166, whereby the through hole 138 formed at the lower end of the center protrusion 136 Is closed.

The inner diameter of the center insertion groove 166 is formed equal to or almost the same as the outer diameter of the center protrusion 136, thereby preventing the first contents 102 from leaking through the center protrusion 136 before the lowering of the piston 160 can do.

The piston protrusion 168 protrudes downward from the lower surface of the center insertion groove 166 and has a hollow cylindrical shape. The piston protrusion 168 is inserted into the cap protrusion 186 formed in the center of the lower cap 180 (see FIG. 1). And as the piston 160 descends, the piston protrusion 168 is completely inserted into the cap protrusion 186 (see FIG. 5). In this way, the piston protrusion 168 serves to guide the piston 160 to stably descend together with the cap protrusion 186.

A taper 170 is formed at the lower end of the piston protrusion 168. The taper 170 facilitates the insertion of the piston protrusion 168 into the inside of the cap protrusion 186.

The lower cap 180 is coupled to the lower part of the second body 130 to cover the open lower part of the second body 130. A cap rib 182 is formed at the edge of the circular lower cap 180, and a cap protrusion 186 is formed at the center thereof.

The cap rib 182 is formed to protrude upward from the edge of the lower cap 180 and is in close contact with the inner circumferential surface of the lower body 146 of the second body 130. Since the cap rib 182 is in close contact with the inner circumferential surface of the lower body 146, the detachment of the lower cap 180 is prevented and the contents can be prevented from flowing out of the mixing container 100.

In addition, the cap rib 182 includes a locking protrusion 184 protruding outward, and the locking protrusion 184 is inserted into a groove (no reference numeral) formed on the inner circumferential surface of the lower body 146. Accordingly, the lower cap 180 is firmly coupled to the lower end of the second body 130.

The cap protrusion 186 protruding upward from the center of the lower cap 180 has a hollow cylindrical structure and its upper part is open. In addition, the length of the cap protrusion 186 may be formed equal to or substantially the same as the piston protrusion 168. In addition, the inner diameter of the cap protrusion 186 may be formed somewhat larger than the outer diameter of the piston protrusion 168. Due to this, the piston protrusion 168 can be easily inserted into the cap protrusion 186.

The mixing container 100 according to the present embodiment may include a dropper 190 as a means for discharging the contents. The dropper 190 includes a dropper cap 194 screwed to an upper portion of the first body 110 and a nozzle 198 extending downward from the dropper cap 194.

The dropper cap 194 may be coupled to the first body 110 in place of the cap 112 after the cap 112 coupled to the upper portion of the first body 110 is removed. A pressing part 192 is formed on the upper part of the dropper cap 194. In addition, a nozzle 198 is inserted in the center of the dropper cap 194.

The nozzle 198 is a long hollow tube whose lower end is open and its upper end is connected to the pressing unit 192. The length of the nozzle 198 may be formed such that it can press the piston 160 when the dropper 190 is coupled to the first body 110. For this reason, in the process of coupling the dropper 190 to the first body 110, the nozzle 198 may press the piston 160 to move downward.

The mixing container 100 according to the present embodiment has been illustrated as having a dropper 190 as a discharging means, but the present invention is not limited by the discharging means of the contents. Therefore, the mixing container 100 according to another embodiment of the present invention may be provided with various discharging means such as a spray pump disclosed by Korean Patent No. 1963619.

4 is a cross-sectional view illustrating a state before the dropper 190 is inserted in the mixing container 100 and the

contents

102 and 104 are mixed, and FIG. 5 is a dropper 190 in FIG. 4 so that the contents are completely inserted. It is a cross-sectional view illustrating a mixed state.

4 to 5, after removing the cap 112 from the mixing container 100 illustrated in FIG. 1, the nozzle 198 of the dropper 190 is opened through the inlet 114 of the first body 110. Insert into the interior of the mixing container (100). At this time, since the piston 160 is inserted into the center protrusion 136 of the second body 130, the second inner space 172 does not communicate with the first inner space 120. Therefore, before the piston 160 is separated from the center protrusion 136, the first contents 102 are not mixed with the second contents 104.

When the nozzle 198 moves downward in the process of screwing the dropper cap 194 of the dropper 190 to the first main body 110, the lower end of the nozzle 198 is the center protrusion of the second main body 130 ( After passing through 136, it is inserted into the center insertion groove 166 of the piston 160 to press the piston 160 downward. Accordingly, while the piston 160 moves downward, the piston protrusion 168 is inserted deeper into the inside of the cap protrusion 186. By the downward movement of the piston 160, the contact state between the center protrusion 136 and the center insertion groove 166 is released, and the through hole 138 is opened. In addition, as the first inner space 120 and the second inner space 172 communicate with each other by the opening of the through hole 138, the first contents 102 flow into the second inner space 172 and the second contents ( 104) and intermixed.

The end of the nozzle 198 of the dropper 190 completely screwed to the first body 110 comes into contact with the bottom surface of the center insertion groove 166 of the piston 160 moved downward. In addition, the piston protrusion 168 is also completely inserted into the cap protrusion 186 of the lower cap 180 so that the piston 160 cannot move any more. As shown in Figure 5, even when the piston 150 is completely moved, the piston rib 164 is in contact with the inner circumferential surface of the insertion head 132, whereby a mixture of the first content 102 and the second content 104 It is prevented from flowing out to the lower portion of the piston 160.

The mixing vessel 100 according to the present embodiment is illustrated by pressing the piston 160 downward using the nozzle 198 of the dropper 190, but the present invention is limited by the means for pressing the piston 160 downward. It doesn't work. Therefore, the mixing container 100 according to another embodiment of the present invention may use a nozzle of a spray pump module or a separately provided stick to press the piston 160 downward.

In the mixing container 100 according to the present embodiment, the first contents 102 and the second contents 104 may be mixed by the downward movement of the piston 160 in the process of screwing the dropper 190, which is the discharge means. It has the advantage of being convenient to use. In addition, the mixing container 100 according to the present embodiment is formed by the first body 110, the second body 130, the piston 160, and the lower cap 180, and the configuration is simple and easy to manufacture and assemble. It also has the advantage of doing it.
