Additive sample bottle

Abstract

The invention discloses an additive sample bottle applied to the field of chemical engineering. The bottle comprises an outer bottle and an inner bottle, wherein an inner cover and an outer cover arearranged on a bottle opening, the outer cover is fixed through lugs on the inner cover, the inner cover is in threaded connection with the sealing bottle opening, and wing edges of the outer bottle are fixed. Pressure springs are arranged in inner step through holes of the inner cover, pressing blocks are arranged in outer steps through holes of the outer cover, and the pressure springs compact the pressing blocks and seal the outer step through holes. The outer bottle is formed by buckling two half-bottle lap joints with observation holes, the observation holes are shielded by a shading piece, and the shading piece can move in a gap between the inner bottle and the outer bottle. The color and smell of additives in the sample bottle are convenient and fast to detect, micro-positive pressure nitrogen in the bottle avoids the long-time contact of the additives and air, the light shielding effect of the outer bottle is good, and the problem of color change of the additives is solved.

Description

technical field [0001] The invention is applied in the field of chemical industry, and relates to a bottle containing lubricating oil additive samples. Background technique [0002] In the chemical industry, lubricating oil is blended by base oil and additives, in which the base oil determines its basic performance, and the additives can effectively make up for and improve the deficiency of the base oil. When selling additives, it is necessary to bring some samples for customers to observe and identify. Typically, customers first identify the color and odor of an additive sample. [0003] The bottle containing the additive sample is the sample bottle, which is made of plastic or glass, usually transparent or brown. The transparent color makes it easy to directly observe the color of the additive sample, but as time accumulates, the additive will deteriorate due to sunlight. The brown color is mainly to prevent direct sunlight, but customers cannot see the color of the add...

AI Technical Summary

Problems solved by technology

Brown is mainly to prevent direct sunlight, but customers cannot see the color of the additive, so they need to pour out part of it for observation, which causes waste of additives

The identification of the odor needs to open the bottle cap of the sample bottle, the additive is inevitably in contact with the air, due to the action of oxygen, together with sunlight, the additive is prone to discoloration and denaturation over time, making the additive scrap

Especially the samples in the product showroom need to be replaced irregularly, resulting in waste of additive samples
