Mode for the Invention [24] Hereinafter, exemplary embodiments of the present invention will be described in detail, with reference to the accompanying drawings. [25] FIG. 1 is a front view illustrating a powder storing container according to one

exemplary embodiment of the present invention, FIG. 2 is a cross-sectional view illustrating a section A as shown in FIG. 1, and FIG. 3 is a perspective view illustrating a powder storing container according to one exemplary embodiment of the present invention.

[26] Referring to FIGS. 1 to 3, the powder receptor portion 110 according to this exemplary embodiment is a portion that contains powder. The powder receptor portion 110 may be formed by attaching two receptor portion forming bodies 111 and 112 to each other. The attachment may be carried out by heat fusion, etc.

[27]

[28] One side, for example a lower portion, of the powder storing container 100 is open to the outside environment, and the powder contained in the powder receptor portion 110 is introduced into the powder receptor portion 110 through the open region. After the introduction of the powder, the open region of the powder-containing powder storing container 100 is attached to hermetically seal a corresponding region of the powder storing container 100. Then, the powder storing container 100 containing the powder is open only in an inflow channel 140 of the check valve 120.

[29] The check valve 120 includes an internal orifice 142 and an external orifice 141. The internal orifice 142 is formed in the powder receptor portion 110, and a certain amount of materials flow in the powder receptor portion 110 through the internal orifice 142. And, the external orifice 141 communicates with the internal orifice 142, and the materials flow in through the external/internal orifices 141 and 142. The internal orifice 142 and the external orifice 141 communicate with each other to form an inflow channel 140.

[30]

[31] The materials flowing in through the check valve 120 may be miscible with the powder contained in the powder receptor portion 110, for example, fluids such as water, etc.

[32] Some region of the check valve 120 other than the internal orifice 142 and the external orifice 141 is attached to each other together with the powder receptor portion 110. Then, the inflow channel 140 formed with the internal orifice 142 and the external orifice 141 is opened to communicate the powder receptor portion 110 with the outside environment. And, the remainders of the powder receptor portion 110 and the check valve 120 are hermetically sealed from the outside environment.

[33] The check valve 120 may be formed by attaching two check valve forming bodies

121 and 122 to each other. In the attachment operation, the external orifice 141 and the internal orifice 142 should not be attached to the two check valve forming bodies 121 and 122. The attachment may be carried out by heat fusion, etc.

[35] The check valve 120 having two check valve forming bodies 121 and 122 attached as described above is disposed between the receptor portion forming bodies 111 and 112 constituting the powder receptor portion 110, and the check valve 120 and the powder receptor portion 110 may be then attached together by attaching the receptor portion forming bodies 111 and 112 together. When the check valve 120 and the powder receptor portion 110 are attached together, the inflow channel 140 communicates with the outside environment through the external orifice 141 and the internal orifice 142, and the remaining region of the powder storing container is hermetically sealed from the outside environment.

[36] The sealing portion 200 hermetically seals at least one of the internal orifice 142 and the external orifice 141 of the check valve 120. Each of the two receptor portion forming bodies 111 and 112 constituting the powder receptor portion 110 extends upward to cover the check valve 120, and the sealing portion 200 may be formed by attaching the extensions to each other. The extensions of the receptor portion forming bodies 111 and 112 may be defined as sealing portion forming bodies 201 and 202. The attachment may be carried out by heat fusion, etc. Of course, the sealing portion 200 may be formed with separate sealing portion forming bodies 201 and 202 attached to the powder receptor portion 110.

[37] The sealing portion 200 has a shape of surrounding the external orifice 141 of the check valve 120, and hermetically seals the external orifice 141 from the outside environment. In this case, materials such as foreign substances may not be introduced through the external orifice 141 of the check valve 120 while the sealing portion 200 is hermetically sealed. Accordingly, as soon as the sealing portion 200 is hermetically sealed, it is recognized from the outside that the foreign substances are not introduced into the powder storing container 100 containing powder. Therefore, it is possible to improve product reliability of the powder storing container 100.

[38]

[39] Meanwhile, when fluids miscible with powder are introduced into the powder receptor portion 110 through the check valve 120 by a user, an upper portion of the sealing portion 200 of the check valve 120 is cut by the user to open the external orifice 141 of the check valve 120.

[40] Then, the fluid is introduced through the opened external orifice 141. The introduced fluid flows then in the powder receptor portion 110 through the internal orifice 142, and the fluid may be mixed with powder contained in the powder receptor portion 110 to form a desired mixture.

[41] Here, the cutting of the sealing portion 200 may be carried out with cutting systems such as knife, scissors, etc. To facilitate the cutting of the sealing portion 200, a cutting-plane line 210 may be marked on the sealing portion 200. The cutting-plane

line 210 may be marked to cut an upper portion of the external orifice 141 of the check valve 120.

[42] Hereinafter, another exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings. Description of the same parts and constitution as described in the one exemplary embodiment is omitted herein for clarity.

[43]

[44] FIG. 4 is a perspective view illustrating a powder storing container according to another exemplary embodiment of the present invention, and FIG. 5 is a cross- sectional view illustrating a section B as shown in FIG. 4.

[45] Referring to FIGS. 4 and 5, the check valve 130 according to this exemplary embodiment may be formed by attaching one check valve forming body 131 to one of the two receptor portion forming bodies 111 and 112. More particularly, one check valve forming body 131 is attached to one of the receptor portion forming bodies without attaching the internal orifice 152 and the external orifice 151. Then, the check valve 130 is formed with the one check valve forming body 131 and one of the receptor portion forming bodies. Then, the check valve 130 and the powder receptor portion 110 may be formed by attaching the other one of the receptor portion forming bodies to the receptor portion forming body in which the check valve 130 has been formed.

[47] Hereinafter, a coupling procedure of the check valve forming body and receptor portion forming body will be described in detail with reference to FIGS. 6 to 9.

[48]

[49] As shown in FIG. 6, the first operation is first to form a check valve 120 by coupling two check valve forming bodies 121 and 122 to each other, and then to couple the check valve 120 to the two receptor portion forming bodies 111 and 112. An inflow channel 140 is formed when the check valve 120 is formed through the attachment operation.

[50] As shown in FIG. 7, the second operation is first to couple one check valve forming

body to one of receptor portion forming bodies 111 and 112, and then to couple another check valve forming body and the other one of the receptor portion forming bodies 111 and 112 to the coupled forming body. An inflow channel 140 is formed when another check valve forming body is coupled to the coupled forming body of the one check valve forming body and the other one of the receptor portion forming bodies 111 and 112.

[51] As shown in FIG. 8, the third operation is first to couple check valve forming bodies

121 and 122 to receptor portion forming bodies 111 and 112 one by one, and then to couple the coupled forming bodies to each other. An inflow channel 140 is formed when the coupled forming bodies, formed by coupling the check valve forming bodies 111 and 112 to the receptor portion forming bodies 111 and 112 one by one, are coupled to each other.

[52] As shown in FIG. 9, the fourth operation is first to couple one check valve forming body 131 to one of receptor portion forming bodies 111 and 112, and then to couple the other receptor portion forming body to the coupled forming body. Here, an inflow channel 150 is formed when the other one of the receptor portion forming bodies 111 and 112 is coupled to the one check valve forming body 131.

[53] In addition to the operations as presented above, various combinations for the attachment of one or two check valve forming bodies and two receptor portion forming bodies 111 and 112 may be proposed to form the check valves 120 and 130.
