3results about How to "Improve drop strength" patented technology

The present invention relates to chemically strengthened glass, a method for producing the same, and glass for chemical strengthening. A chemically strengthened glass is a plate-shaped chemically strengthened glass having a compressive stress layer on a glass surface, in which a compressive stress value (CS0) of the glass surface is 500 MPa or greater, a plate thickness (t) is 400 μm or greater, a compressive stress layer depth (DOL) is (t x 0.15) μm or greater, a compressive stress value (CS1) at a position at a depth of 1 / 4 of the DOL from the glass surface and a compressive stress value (CS2) at a position at a depth of 1 / 2 of the DOL from the glass surface are each 50 MPa or greater, m1 represented by {m1 = (CS1-CS2) / (DOL / 4-DOL / 2)} is -1.5 MPa / μm or greater, m2 represented by {m2 = CS2 / (DOL / 2-DOL)} is 0 MPa / μm or less, and m2 is less than m1.

The utility model relates to the technical field of cosmetic bottles, in particular to an anti-falling cosmetic bottle which comprises an inner bottle body, cosmetic stock solution is filled in the inner bottle body, an inner bottle cap is arranged at the upper end of the inner bottle body, and a liquid outlet is formed in the upper end of the inner bottle cap. An anti-falling assembly is arranged outside the inner bottle body and comprises an outer bottle body, the inner wall of the outer bottle body is connected with the outer wall of the inner bottle body through a plurality of elastic bars, and an outer bottle cap is arranged on the upper portion of the outer bottle body. And the outer bottle cap is covered on the inner bottle cap. According to the anti-falling cosmetic bottle, the cosmetic bottle can be effectively protected through the external anti-falling assembly, the anti-falling strength of the whole cosmetic bottle is practically improved, normal use of cosmetics is protected, the overall service life is prolonged, waste of the cosmetics is reduced, and the anti-falling cosmetic bottle is convenient to widely popularize and use.
