Best Mode for Carrying Out the Invention [28] Reference will now be made in detail to the preferred embodiments of the present invention. It is to be understood that the following examples are illustrative only and the present invention is not limited thereto. [29] Referring to FIGs. 1 to 13, a blood sampling container according to embodiments of the present invention includes a sampling container 10 having an internal space 11 filled with blood therein, and a cap 15 coupled to an upper portion of the sampling container by a coupling part 14 for opening and closing the upper portion. [30] The sampling container 10 includes an internal lock part 20 having a hemispheric engaging groove 21 formed on an upper inner periphery of the inner space 11, and an engaging boss 22 formed on an outer periphery of the cap and engaged with the engaging groove. [31] Also, the blood sampling container comprises a lock releasing part 40 having a locking portion 41 protruding vertically from a front end portion of the cap 15, an open lever 42 for pushing up the locking portion 41, and a support 45 protruding inwardly from the open lever 42 and pivoting around a hinge 43 provided on a front end of the sampling container 10. [32] Also, the blood sampling container comprise an external lock part 30 having a locking boss 31 vertically protruding from an outer periphery of the cap 15, and a stepped portion 32 formed on the upper periphery of the blood container 10 and being engaged with the locking boss 31. [33] In this instance, the locking portion 41 has an inclined surface 41' to support the support 45 of the opening lever 42 towards an exterior.

[34] Although two locking bosses 31 of the external lock part 30 are provided in a direction perpendicular to the locking portion 41 of the cap 15 in the figures, the position and number of the locking bosses 31 are not limited. The modification and alternation of the locking boss 31 are not deviated from the scope of the present invention.

[35] Reference numeral 46 denotes a penetrating portion formed on the lock releasing portion 40, and 50 denotes a reinforcing rib.

[36] The operation of the blood sampling container of the present invention will now be described.

[37] The present invention is characterized in that the lock parts 20 and 30 are provided on the inner and outer portions of the cap to easily engage and disengage the cap 15 to or from the blood container 10 in one touch operation and maintain the air tightness between the blood container and the cap.

[38] More specifically, the inner space 11 of the sampling container 10 is filled with the blood, and then the sampling container 10 is closed by the cap 15.

[39] The cap 15 pivots around the coupling part 14 of the cap 15 to engage to the sampling container 10.

[40] In this case, the cap 15 is rigidly locked by the inner and outer lock parts 20 and 30.

[41] With the construction of the inner lock part 20, a plug 16 of the cap 15 is inserted in the inner space 11 of the sampling container 10, and the engaging groove 21 formed on the inner space 11 is resiliently engaged with the engaging boss 22 formed on the outer periphery of the plug 16.

[42] The outer lock part 30 is locked by resiliently engaging the locking boss 31 vertically protruding from the outer periphery of the cap 15 with the stepped portion 32 formed on the upper outer periphery of the sampling container 10.

[43] Consequently, the cap 15 is locked at the inner and outer portions of the sampling container 10, thereby increasing the engaging force of the cap 15 and thus maintaining the air tightness therebetween.

[44] In case of opening the cap 15, the open lever is 42 is pushed down in one touch operation to release the locking state of the cap 15 and thus open the cap 15.

[45] More specifically, the locking portion 41 protruding from the front end of the cap urges the support 45 of the open lever 42 when the cap 15 is engaged, the open lever 42 pivots around the hinge 43 together with the support 45, and the locking portion 41 is supported by the support 45.

[46] In particular, since the inclined surface 41' is formed on the outer surface of the locking portion 41, the support 45 of the open lever 42 is supported by the inclined surface 41' of the locking portion 41. Therefore, the open lever 42 is upwardly and outwardly inclined. [47] Consequently, by pushing down the open lever 42 inclined downwardly, the open lever 42 pivots the hinge 43 to upwardly lift the locking portion 41 supported by the support 45. [48] As the locking portion 41 formed on the front portion of the cap 15 is upwardly lifted, the cap 15 which is locked by the inner and outer lock parts 20 and 30 is released from the lock state, so that the cap 15 is easily detached from the sampling container 10. [49] The blood sampling container of the present invention includes the plurality of inner and outer lock parts 20 and 30 to maintain the air tightness of the cap 15. But, only the inner lock part 20 or outer lock part 30 may be provided to maintain the air tightness. In this instance, the cap 15 can be easily released from the lock state by using the lock releasing part 40 to open the cap 15. [50] Also, the blood sampling container of the present invention may be applied as shown in FIG. 14, in which a cylindrical support 50 is integrally extended from the lower portion of the blood sampling container 10. [51] Since the cylindrical support 50 is integrally formed on the lower portion of the sampling container 10, the sampling container 10 can stand on a table. Also, when the sampling container 10 is inserted in a rod such as a pipe, it can stand therein. [52] In other words, the sampling container 10 can stand on the table, without using a separate nest, with the sampling container 10 being filled with its contents.

Industrial Applicability

[53] As can be seen from the foregoing, according to the blood sampling container of the present invention, it has lock members at the upper portion thereof which are engaged to each other to easily maintain good fluid tightness therebetween, thereby preventing inflow of alien substances and outflow of the blood and maximizing its convenience by easily opening and closing the locking members in one touch operation.

[54] While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiment and the drawings. On the contrary, it is intended to cover various modifications and variations within the spirit and scope of the appended claims.
