Resumo
O design de embalagens de produtos de consumo deve atender a vários aspectos como segurança, conforto, eficácia, estética, entre outros. Estes elementos devem contemplar as características e capacidades dos usuários, considerando especialmente a força manual no design ergonômico das embalagens, com o objetivo de disponibilizar produtos confiáveis e seguros, de fácil acesso para usuários com capacidades limitadas (idosos) ou de difícil acesso para aqueles indivíduos que não são usuários e não deveriam acessar o produto (crianças). A falta de parâmetros biomecânicos adequados e confiáveis, de todas as faixas populacionais, incluindo as crianças, parece ser uma das causas que ainda impede os designers e a indústria de embalagens de desenvolver produtos com tampas que não impedem a ocorrência de acidentes e estão relacionados a elevados números de intoxicações envolvendo crianças. Por este motivo, o propósito desta pesquisa foi verificar as forças de manipulação empregadas durante a abertura de embalagens de água sanitária, especificamente a força de torção, ou torque, exercida por crianças (faixa etária de 2 a 5 anos) na abertura de tampas com sistema de rosca, visando apresentar parâmetros mínimos para o projeto de embalagens com tampas seguras. A metodologia empregada nesta pesquisa envolveu a utilização de três embalagens reais, adaptadas para a mensuração de torque. As três tampas analisadas possuíam dimensões diferentes e os resultados indicam uma forte influência desta variável na capacidade de aplicação de torque pelos sujeitos. Neste sentido, as dimensões recomendadas para as tampas de produtos com potencial tóxico devem ser próximas às apresentadas pela tampa de menor diâmetro desta avaliação, cujo design permitiu menor capacidade de aplicação de torque pelas crianças, o que dificultaria o acesso das mesmas, numa situação...
The design of consumption products packs must take care ofsome aspects, as security, comfort, effectiveness, aesthetic, among others. These elements must especially contemplate the characteristics and capacities of hte users, being considered the manual force in ergonomic design of the packs, with the objective of to make available trustworthy and safe products, or still, easy access for those users with limited capacities (aged) or difficult access for those individuals that are not using and they must not have access the product (children). The lack of adequate and trustworthy biomechanic parameters, of all the population bands, including the childre, seems to be one of the causes that still designers hinders and the industry of packs to developed products with really safe covers. Products with high toxic potential, as the sanitary water, are available in packs with covers that do not hinder the occurrence of accidents and, for this and other reasons are related the raised numbers of poisonings involving children. In this way, the intention of this research was to verify the used forces of manipulation during the opening of sanitary water packs, specifically the torsional force, or torque, exerted for children (age band between 2 and 5 year) in the opening of covers with thread system, aiming at to present minimum parameters for the project of packs with safe covers. The methodology used in this research involved the use of three real packs, adapted for the measure of torque. The three analyzed covers had different and the results indicate one strong influence of this variable in the capacity of aplication of torque for the citizens. In this direction, the dimensions recommended for the covers of products with toxic potential must be next to the presented ones for the cover to lesser diameter of this evaluation, whose design allowed to minor capacity of application of torque...
