Abstract

A clean container having an elastic positioning structure includes a support element and a back positioning element on a base. A cover is disposed for covering the base, and a positioning part is disposed between the cover and the base, which has two elastic arms extended laterally, and each elastic arm extends with a pushing surface respectively. When a plate of brittle material is placed on the base, and the cover is closed, the pushing surfaces are elastically pressed against and push the plate respectively, so that the plate moves backwards and presses against the back positioning element. Therefore, the plate is prevented from being damaged. Additionally, the base, the cover, and the positioning part are made of a conductive material, so that the electrostatic charges for the plate is conducted out of the clean container, and has a protective function of an electrostatic discharge.

Claims (38)

1. A clean container having an elastic positioning structure, comprising:

a base, having an upper surface with at least one support element, at least one lateral positioning element, and at least one back positioning element being disposed thereon;

a cover, for covering the base firmly, and having a top plate with an upper surface and a lower surface; and

a positioning part, disposed on the lower surface of the cover, and having a body, and a front end corresponding to the at least one back positioning element, and a back end opposite to the front end, wherein

the front end has a first elastic arm and a second elastic arm extended laterally, end surfaces of the first elastic arm and the second elastic arm respectively facing downward and backward to form a pushing surface;

the back end has a third elastic arm and a fourth elastic arm extended laterally, the third and fourth elastic arms each having a flange formed on a bottom thereof; and

the back end of the positioning part is further formed with at least one snapping arm having at least one downward groove corresponding to the at least one back positioning element of the base, such that the at least one groove is snapped with the at least one back positioning element after the cover is snapped with the base.

2. The clean container having an elastic positioning structure as claimed in claim 1 , wherein the top plate further comprises at least one through-hole penetrating through the upper surface and the lower surface, the positioning part has at least one stud corresponding to the through-hole on a top surface of the body, and the top plate further has a mounting plate screwed on the upper surface, and the mounting plate is screwed to the stud on the positioning part by means of passing a bolt through the through-hole of the top plate.

3. The clean container having an elastic positioning structure as claimed in claim 1 , wherein the pushing surface is an inclined plane or a curved surface.

4. The clean container having an elastic positioning structure as claimed in claim 1 , wherein the end surfaces of the first elastic arm and the second elastic arm are respectively formed into a positioning surface, adjacent to an external side of the pushing surface.

5. The clean container having an elastic positioning structure as claimed in claim 1 , wherein the third elastic arm and the fourth elastic arm respectively comprise a positioning slant on an external side of an end surface thereon.

6. The clean container having an elastic positioning structure as claimed in claim 1 , wherein the base and the cover further comprise at least one snapping element, so as to snap the cover with the base firmly.

7. The clean container having an elastic positioning structure as claimed in claim 1 , wherein the base, the cover, and the positioning part are made of a conductive material.

8. A cleaning container having an elastic positioning structure, comprising:

a base, having an upper surface with at least one support element, at least one lateral positioning element, and at least one back positioning element being disposed thereon;

a cover, for covering the base firmly, and having a top plate, wherein the top plate comprises an upper surface and a lower surface, and the lower surface of the top plate has a first engaging element; and

a positioning part, disposed on a lower surface of the cover, and having a body, a front end corresponding to the at least one back positioning element, and a back end opposite to the front end, wherein

the front end includes a first elastic arm and a second elastic arm extended laterally, end surfaces of the first elastic arm and the second elastic arm respectively facing downward and backward to form a pushing surface;

the back end has a third elastic arm and a fourth elastic arm extended laterally, the third and fourth elastic arms each having a flange formed on a bottom thereof;

a top surface of the body includes a second engaging element corresponding to the first engaging element, the first engaging element and the second engaging element forming an engaging structure, so as to embed the positioning part to the lower surface of the cover; and

the back end of the positioning part is further formed with at least one snapping arm having at least one downward groove corresponding to the at least one back positioning element of the base, such that the at least one groove is snapped with the at least one back positioning element after the cover is snapped with the base.

9. The clean container having an elastic positioning structure as claimed in claim 8 , wherein the first engaging element is at least one groove, and the second engaging element is a post corresponding to the groove.

10. The clean container having an elastic positioning structure as claimed in claim 8 , wherein the first engaging element is at least one post, and the second engaging element is a groove corresponding to the post.

11. The clean container having an elastic positioning structure as claimed in claim 8 , wherein an upper surface of the top plate further has a mounting plate screwed thereon, and the mounting plate is fixed on the cover through screwing a bolt to a corresponding nut hole in an upper surface of the cover.

12. The clean container having an elastic positioning structure as claimed in claim 8 , wherein the pushing surfaces on the first elastic arm and the second elastic arm are an inclined plane or a curved surface.

13. The clean container having an elastic positioning structure as claimed in claim 8 , wherein the end surfaces of the first elastic arm and the second elastic arm respectively form a positioning surface, adjacent to an external side of the pushing surface.

14. The clean container having an elastic positioning structure as claimed in claim 8 , wherein the third elastic arm and the fourth elastic arm respectively comprise an positioning slant on an external side of an end surface thereof.

15. The clean container having an elastic positioning structure as claimed in claim 8 , wherein the base and the cover further comprise at least one snapping element, so as to snap the cover with the base firmly.

16. The clean container having an elastic positioning structure as claimed in claim 8 , wherein the base, the cover, and the positioning part are made of a conductive material.

17. A clean container having an elastic positioning structure, comprising:

a base, having an upper surface with at least one support element, at least one lateral positioning element, and at least one back positioning element being disposed thereon;

a cover, for covering the base firmly, and having a top plate with an upper surface and a lower surface; and

a positioning part, disposed on the lower surface of the cover, and having a body, and a front end corresponding to the at least one back positioning element,

wherein the front end has a first elastic arm and a second elastic arm extended laterally, end surfaces of the first elastic arm and the second elastic arm respectively facing downward and backward to form a pushing surface, and

wherein the top plate further comprises at least one through-hole penetrating through the upper surface and the lower surface, the positioning part has at least one stud corresponding to the through-hole on a top surface of the body, and the top plate further has a mounting plate screwed on the upper surface, and the mounting plate is screwed to the stud on the positioning part by means of passing a bolt through the through-hole of the top plate.
