  As shown in the drawing, the pump type liquid hermetic container according to an embodiment of the present invention includes a main body 100, a connection cover 200, a check plate 300, an elastic pump 400, and a discharge button 500 (see FIG. 1 and FIG. 1). (See FIG. 2).

  The main body 100 has a cylindrical shape with an open top, has a length, is long, and forms a storage space 101 for storing liquid contents therein. The main body 100 is made of a transparent material having a predetermined strength such as plastic or acrylic and capable of identifying the contents.

  The main body 100 is open at the top, and the connecting cover 200 is coupled to the top of the main body 100 to form the housing space 101. The main body 100 is coupled to the connection cover 200 by various methods, and it is preferable that the main body 100 is detachably coupled to the connection cover 200 by a fitting connection method.

  The main body 100 is made of a transparent material and is detachably coupled to the connection cover 200 so that the user can easily identify the remaining amount of the contents stored in the main body 100. 200 has an advantage that the storage space 101 can be filled with contents.

  The content stored in the storage space 101 of the main body 100 means a liquid substance such as cosmetics and medical reagents, and may also include a gel substance having a predetermined viscosity.

  The connection cover 200 is detachably fitted into an upper portion opened by the main body 100 to define the accommodation space 101 and form an arrangement space 202 having an upper portion opened. The connection cover 200 includes a communication port 201 that allows the accommodation space 101 and the arrangement space 202 to communicate with each other at a lower portion toward the accommodation space 101.

  The connection cover 200 is preferably made of a material such as plastic or acrylic, like the main body 100, and has a cylindrical shape with an open top. In addition, the arrangement space 202 of the connection cover 200 is a space in which the elastic pump 400 is provided and at the same time a fitting space in which the elastic pump 400 is fitted.

  The connection cover 200 further includes a discharge guide tube 204 on the bottom surface. The discharge guide tube 204 is formed to protrude from the bottom surface of the connection cover 200 toward the accommodation space 101 and has a structure that covers and surrounds the communication port 201. The discharge guide pipe 204 is preferably integrated with the connection cover 200 and allows the communication port 201 and the accommodation space 101 to communicate with each other.

  When the pump-type liquid hermetic container is used for the first time, the discharge guide tube 204 discharges the air remaining in the storage space 101 to the outside, so that the content of the discharge guide tube 204 is positioned on the content full line Z. A vacuum pressure is generated in the moving flow path 401 and the accommodating space 101 of the elastic pump 400 by being located below the material full line Z and partially immersed in the contents.

  In addition, the discharge guide tube 204 increases the suction input by the vacuum pressure on the communication port 201 side when the discharge button 500 is driven up and down to discharge the contents, and the contents are moved by the elastic pump 400. It is possible to effectively flow into the path 401.

  The check plate 300 is lifted and lowered by the vacuum pressure generated by the operation of the discharge button 500 in a state of being provided in the communication port 201 provided at the lower part of the connection cover 200, and closes or opens the communication port 201. The check plate 300 is preferably made of a flexible material such as silicon.

  For example, the check plate 300 closes the communication port 201 when the discharge button 500 is pressed, so that the contents accommodated in the elastic pump 400 are discharged to the outside through the discharge button 500 by vacuum pressure. To be.

  On the other hand, when the discharge button 500 is moved up and down and restored to the position before being pushed, the check plate 300 rises to open the communication port 201, and the contents stored in the storage space 101 are It can be moved to the elastic pump 400 side. The check plate 300 descends after the contents are moved, and closes the communication port 201 again.

  The elastic pump 400 is made of a flexible material such as silicon, is formed long, and is provided in the arrangement space 202 of the connection cover 200. The elastic pump 400 includes therein a moving flow path 401 that is formed long along the longitudinal direction.

  As described above, the movement flow path 401 of the elastic pump 400 communicates with the accommodation space 101 when the communication port 201 is opened due to the rising of the check plate 300 so that the contents move to the elastic pump 400 side. To.

  Since the elastic pump 400 has a difference in the thickness of the side surface for each section, when the user pushes the discharge button 500, the thickness is small and the section located in the arrangement space 202 is contracted, and the moving flow path 401 is compressed. A vacuum pressure is generated (see FIG. 3).

  On the other hand, when the external force applied to the discharge button 500 is removed, the elastic pump 400 restores the contracted section to its original form, raises the discharge button 500, returns it to its original position, It flows into the movement flow path 401 (refer FIG. 4).

  The elastic pump 400 is fitted in the arrangement space 202 of the connection cover 200, and the upper part thereof is fastened to the discharge button 500. The form is deformed or restored by an external force, and generates a vacuum pressure for moving the contents. As a result, the structure of the liquid hermetic container can be simplified, and the contents can be effectively discharged.

  The discharge button 500 includes a discharge path 501 and a sealing protrusion ring 502, and is fitted into and coupled to the open upper portion of the connection cover 200.

The discharge tube 402 has the smallest thickness in the elastic pump 400 and is a section adjacent to the discharge path 501. The shape of the discharge tube 402 is deformed when a vacuum pressure is generated.

  The discharge path 501 of the discharge button 500 allows the outside to communicate with the moving flow path 401 so that the contents are discharged to the outside. The discharge path 501 is positioned adjacent to the discharge tube 402 of the elastic pump 400 so that when the discharge tube 402 is warped by an external force, the moving flow path 401 and the outside communicate with each other.

  In the pump-type liquid hermetic container according to the embodiment of the present invention having the above-described configuration, the connection cover 200 in which liquid or gel-like contents are stored in the storage space 101 of the main body 100 and the communication port 201 is provided.

The moving flow path 401 is sealed, the elastic pump 400 causes the contents to flow into the moving flow path 401, and the discharge tube 402 is brought to a vacuum pressure. By discharging the contents into the discharge passage 501, the liquid or gel-like contents can be discharged effectively without any excess, simplifying the structure and increasing the sealing force. Deriving the effect.

  Meanwhile, the discharge button 500 forms a communication channel 503 connected to the discharge channel 501. The communication channel 503 provides a space such that the discharge tube 402 is deformed by the vacuum pressure generated by the pressing operation of the discharge button 500 in a state where the contents are accommodated in the moving channel 401.

  In addition, the communication channel 503 communicates between the discharge channel 501 and the moving channel 401 of the elastic pump 400 when the discharge tube 402 is deformed and warps toward the discharge channel 501 (toward the outside). As a result, the effect of smoothly discharging the liquid or gel-like contents to the outside is derived.

  At this time, the discharge button 500 is in a lowered state so that a vacuum pressure is applied to the check plate 300, the check plate 300 closes the communication port 201 of the connection cover 200, and the contents are discharged. It is made to discharge between the tube 402 and the sealing protrusion ring 502 (refer FIG. 3).

The insertion ring 301 has a ring shape and is fitted into the insertion portion 203 of the connection cover 200. The insertion ring 301 is made of a silicon material and is made of a material having a predetermined strength.

  The opening / closing member 302 has a form corresponding to the internal form of the communication port 201, and is raised and lowered by vacuum pressure to open or close the communication port 201. The opening / closing member 302 is connected to the insertion ring 301 by a connecting rib 303 so that the opening / closing member 302 is not lifted into the accommodation space 101 or the moving flow path 401 together with the contents when the discharge button 500 is pushed up and down.

  The connecting rib 303 is preferably made of a stretchable material, extends from the inner peripheral surface of the insertion ring 301, is connected to the outer peripheral surface of the opening / closing member 302, and includes a plurality. Therefore, the connecting rib 303 leads to the effect of raising and lowering the opening / closing member 302 while being connected to the insertion ring 301 (see FIG. 5).

  In addition, the present embodiment further includes a lifting piston 600 disposed in the accommodation space 101 of the main body 100. The lifting piston 600 has a plate shape and is disposed so as to be freely raised in the housing space 101. The lifting piston 600 is raised by a vacuum pressure and pushes the contents to the moving flow path 401 side of the elastic pump 400.

  The lifting piston 600 divides the accommodation space when it is raised, and forms an air inflow space 103 in the accommodation space 101 through which air flows in through an inlet 102 formed in the lower part of the main body 100.

  That is, when the content is discharged to the outside through the discharge path 501 of the discharge button 500, the lifting piston 600 pushes up the content that moves through the communication port 201 when the position of the discharge button 500 is restored. , It rises in proportion to the amount of movement of its contents. By raising and lowering the discharge button 500, the lifting piston 600 repeatedly discharges the contents to the elastic pump 400 side, thereby allowing the contents of the storage space 101 to be discharged to the outside without leaving a surplus.
