The raw aluminum is well characterized by its ductility, airtightness and safety, and it’s commonly used in the manufacture of packaging such as medicine, ointment, cream, glue and adhesive etc.. and is closely related to people’s daily life. People with normal eyesight can identify the feature, safety and usage of the product visually from the instruction and images on the packaging etc.. But people with visual disability will necessarily request some physical signs or patterns to perceive and identify the products. Some small tangible marks or signs on the aluminum collapsible tube can dramatically increase cause the attention of the people with visual impairments.
The International Standards Organization has specially developed a series of tactile warning signs for the blind. The tactile warning signs are presented with some fixed forms, including three triangles, five triangles or three circles. All these signs are in specific size, and and placed in the certain position like on the shoulder of the aluminum empty tube, so that it is easy to be touched, and identified, instead of be missed or mixed up. For instance when the blind takes a product package such as an aluminum tube with glue, he can feel this sign on the certain position, then immediately gets the warning.
These raised geometric signs specially designed for the blind, although without bright colors, are significant and important for the visually impaired. Blind people will be aware of the dangerous or chemical items contained in the packaging. For example, when the blind touched the triangle signs on the shoulder of the aluminum soft tubes, he will be sensitive that the tubes may contain glue or adhesive etc..
Many manufacturers know that products must meet safety standards, but they rarely pay attention to the packaging of products。 This set of specifications for blind warning signs for packaging aluminum tubes has been followed by many countries in Europe, including Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal , Spain, Switzerland and the United Kingdom. We hoped that more and more countries join in and create more warning signs for vulnerable groups (not just blind people) to help them to easily touch and identify the signs. Let’s get started with the small patterns for packaging aluminum tubes, and bring more people’s attention and create a safer living environment together.
