A non-direct contact bisphenol A protection tool for thermal paper

Abstract

This utility model discloses a non-direct contact bisphenol A (BPA) protection tool for thermal paper. In use, the thermal paper is sandwiched between a cover plate and a base plate and placed within the thermal paper placement area, aligning the output text on the thermal paper with the indicator line. When an indicator pen is used to trace the indicator line, a first magnetic material is attracted and moves towards the upper surface of the bottom, creating a noticeable color difference. The user can then observe through the transparent cover plate that the preset geometric shape corresponding to the output text on the thermal paper has become a marked state. This replaces the current method where most workers use their fingernails to scratch thermal paper documents. Furthermore, the marks can be removed with an eraser, allowing for reuse. The technical solution provided by this utility model is simple in structure, low in cost, and easy to implement, allowing workers in public places to avoid or reduce BPA exposure, which is of great significance in reducing occupational health risks.

Description

Technical Field

[0001] This utility model relates to the field of bisphenol A protection technology, and in particular to a non-direct contact bisphenol A protection tool for thermal paper. Background Technology

[0002] With the rapid development of modern life, thermal paper has been widely used in various fields, such as supermarket receipts, ATM printer paper, restaurant invoices, and other applications requiring instant record generation. However, thermal paper contains bisphenol A (BPA), an important organic chemical raw material widely used in food containers, water bottles, and thermal paper. Studies have shown that BPA poses potential health risks and may have negative effects on human health; long-term low-dose exposure may affect the functions of the endocrine, reproductive, and nervous systems, and is associated with the occurrence of diseases such as obesity, diabetes, and cardiovascular disease, especially posing greater risks to vulnerable groups such as children and pregnant women.

[0003] Among the many applications of thermal paper, the health risks associated with bisphenol A (BPA) exposure are particularly prominent in the catering industry. For example, the practice of catering staff scratching off menus on receipts with their fingernails, seemingly a simple routine, can actually increase the health risk of BPA exposure through various means. Furthermore, when catering staff do not wash their hands properly during serving, the risk of cross-contamination with other customers is increased.

[0004] In response to the problem that the catering industry relies on thermal paper and that service staff are accustomed to scratching thermal paper menus with their fingernails, it is necessary to design a tool that allows employees to avoid direct contact with thermal paper, thereby avoiding or reducing the risk of occupational exposure, while considering environmental protection, health and practicality.

[0022] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Provides a non-direct contact bisphenol A protection tool for thermal paper, such as... Figures 1 to 2 As shown, it includes an indicator pen 300, and a base plate 100 and a cover plate 200 connected together by a bend. The base plate and the cover plate can rotate relative to each other along the bend to form an open or closed state; thermal paper 400 is placed between the cover plate and the base plate.

[0024] The cover plate is made of transparent material; the bottom plate has multiple closed cavities 102, and a first magnetic material 103 is disposed in the closed cavity; the color of the first magnetic material is set to be a contrasting color with the color of the bottom plate. For example, if the bottom plate is white, then the first magnetic material is black or dark blue magnetic powder.

[0025] Multiple cavities are arranged at uniform intervals, either horizontally or vertically, to form indicator lines 101; the intervals of the indicator lines correspond to the intervals of the output characters 401 on the thermal paper. In the default state, the first magnetic material is located at the bottom of the cavity, and the faint indicator lines are faintly visible through the cover plate.

[0026] The base plate has a rectangular thermal paper placement area 105. The length of the indicator line is longer than the length of the thermal paper placement area, and its extension beyond the placement area forms a preset geometric shape, such as a circle or a pentagon. When the thermal paper is placed within the placement area, each line of output text on the thermal paper corresponds to the indicator line and also to the preset geometric shape at the extension of the indicator line.

[0027] The pointer pen contains a second magnetic material 301 with the opposite polarity to the first magnetic material. When the pointer pen approaches and moves along the pointer line, based on the principle of attraction between opposite poles, the first magnetic material moves towards the upper surface of the base plate and gathers to form a noticeable color difference. Users can observe that the pointer line and preset geometric shapes corresponding to the output text are marked on the thermal paper.

[0028] After marking is completed, based on the principle of like poles repelling each other, the marking can be removed by contacting the back of the base plate with an erasing pen containing the third magnetic material 501 and moving it along the indicator line, so that the first magnetic material moves to the lower surface of the cover plate.

[0029] Furthermore, in a preferred embodiment, the cover plate is the same size as the base plate to facilitate their bonding; the cover plate includes a transparent film and a frame surrounding the transparent film, wherein the transparent film is lighter and thinner, making the product more portable.

[0030] Furthermore, the area of ​​the base plate is larger than that of the cover plate, and a groove 104 is provided on the upper surface of the base plate. The groove is used to accommodate the indicator pen, and the groove is convenient for storing the indicator pen.

[0031] Furthermore, a fourth magnetic material 501 with the same polarity as the first magnetic material is disposed inside the end of the pointer pen; when the end of the pointer pen contacts the back of the base plate and moves along the pointer line, the first magnetic material moves toward the lower surface of the cover plate. That is, the functions of the pointer pen and the erasing pen are integrated into one pen barrel, which can save placement space.

[0032] Furthermore, a damped hinge is used at the turning point, making the opening and closing of the cover and base plates more tactile and more stable when holding the thermal paper. This can be understood as the turning point could also use other hinges or hinges, which will not be elaborated upon here.

[0033] The above is a description of the non-direct contact bisphenol A protection tool for thermal paper according to this utility model, which is used to help understand this utility model. However, the implementation of this utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of this utility model shall be considered as equivalent substitutions and shall be included within the protection scope of this utility model.
