Definitions

  • the present invention patent application refers to a hermetic-closing package with a single detachable seal joined by ultrasonic welding, which will be applied to the field of packaging and closing methods.
  • Ultrasonic welding is understood as the ultrasonic welding of thermoplastics by complementary joining or joining of material at a molecular level.
  • packaging will be used as a reference to plastic pots, of the most varied models.
  • jars with pressure-closing lids are commercialized, as presented in patent document BRPI701 105-9, this model of jar is not safe against accidental opening and is mainly contraindicated for packaging liquid or pasty products.
  • pot models are formed by a first threaded lid and internally also feature a second anti-tamper lid in the form of a seal, such as the one presented in patent document BRPI0702715-5, for opening which the seal is broken and discarded and the second lid used as the only lid after opening.
  • This closure model makes the production process costly, whether due to the use of press and machinery for its application which results after opening the bottle in residue to be discarded, as well as requiring the use of the first cap.
  • lid after being opened, can be used again to close the pot.
  • Another objective is to create a pot with a lid that has a ring to facilitate opening and closing handling.
  • Another objective is for the pot to have only a single closing seal, eliminating the need for a second anti-tamper lid in the form of a seal.
  • Figure 1 presents a rear perspective view showing the pot partially opened.
  • Figure 2 shows a sectional view AA, indicated in figure 1, showing the partially open port at the point of rupture of the weakening line.
  • Figure 3 shows a view of the pot with enlarged detail to illustrate and indicate the ultrasonic welding line between the edge of the lid and the pot.
  • Figure 4 shows a sectional view AA, indicated in figure 3, with enlarged details showing the raised ring and the ultrasonic welding line and weakening line.
  • Figure 5 shows a perspective view of the closed pot.
  • Figure 6 shows a top view.
  • Figure 7 shows a top view of the pot with the lid partially open.
  • Figure 8 presents a perspective view of the pot in an alternative construction, showing a recess in the pot rim.
  • Figure 9 shows a partial exploded view of the lid and pot, in their alternative construction.
  • Figure 10 presents an enlarged view showing the recess in the pot rim and the projection of the lid, before ultrasonic welding occurs.
  • Figure 1 1 presents an enlarged view showing the recess in the pot rim and the projection of the lid, after ultrasonic welding has occurred.
  • this application is formed by a container (1) with an upper edge (2) equipped with a smooth and straight flap (3) that projects outwards, contouring the entire upper extension of said edge. top (2).

Description

“EMBALAGEM COM FECHAMENTO HERMÉTICO COM LACRE ÚNICO DESTACÁVEL UNIDO POR SOLDA ULTRASSÓNICA”.
CAMPO DE APLICAÇÃO
[001 ] A presente solicitação de patente de invenção refere- se a uma embalagem com fechamento hermético com lacre único destacável unido por solda ultrassónica, a qual será aplicada ao campo de embalagens e métodos de fechamento.
ESTADO DA TÉCNICA
[002] Entende-se por solda ultrassónica a soldagem por ultrassom de termoplásticos por união complementar ou de material a nível molecular.
[003] O termo embalagem será usado como referência à potes plásticos, dos mais variados modelos. Na técnica atual potes com tampas com fechamento por meio de pressão são comercializados, como apresentado no documento de patente BRPI701 105-9, este modelo de pote não apresenta segurança contra abertura acidental sendo contraindicado principalmente para acondicionar produtos líquidos ou pastosos.
[004] Outros potes são apresentados com tampa e lacre lateral como as tampas utilizadas em potes de sorvete, como apresentado no documento de patente BRMU8502287-0 e BRMU7601554-8, porém estes modelos exigem a necessidade de máquinas especiais para sua produção e não são indicadas para o acondicionamento e transporte de produtos líquidos.
[005] Outros modelos de pote são formados por uma primeira tampa com rosca e internamente ainda apresentam uma segunda tampa anti-violação na forma de lacre, como o apresentado no documento de patente BRPI0702715-5, que para sua abertura o lacre é rompido e descartado e a segunda tampa utilizada como única tampa após sua abertura. Este modelo de fechamento torna o processo produtivo oneroso seja pelo uso de matéria- prima e maquinário para sua aplicação que resulta após a abertura do frasco em resíduo a ser descartado, bem como necessita do uso da primeira tampa.
[006] Nos modelos atuais não se observa o uso de uma única tampa que funciona como um lacre anti-violação em que o mesmo após ser aberto pode ser novamente utilizado para fechar o pote.
[007] Destaca-se que esta técnica se tornou possível através da construção de uma tampa que se encaixa na parte superior do pote para que a mesma receba uma solda ultrassónica lacrando hermeticamente o pote, detalhe construtivo este que será detalhado abaixo.
OBJETIVOS DA INVENÇÃO
[008] Tem como objetivo obter o fechamento de forma hermética entre a tampa e o pote através de um processo de solda ultrassónica.
[009] Outro objetivo é que a tampa após sua abertura possa ser novamente utilizada para fechar o pote.
[010] Outro objetivo é criar um pote com uma tampa que apresente uma argola para facilitar o manuseio de abertura e fechamento.
[01 1 ] Também é objetivo que a tampa possa ser destacada de forma rápida, sem travamentos ou deformações.
[012] Outro objetivo ainda é que o pote tenha apenas um único lacre de fechamento, dispensando o uso de uma segunda tampa anti- violação na forma de lacre.
DESCRIÇÃO DAS FIGURAS
[013] O desenho em anexo expõe o pote plástico com fechamento hermético com tampa destacável unida por solda ultrassónica, que conjuntamente com as referências numéricas detalhadas a seguir, faz-se entender mais facilmente, embora este invento seja susceptível de concretização em muitas formas construtivas diferentes, sempre customizados para cada aplicação, não mostrados nos desenhos que serão aqui descritos em detalhe e formas para a realização do referido invento.
[014] A figura 1 apresenta uma vista posterior em perspectiva mostrando o pote parcialmente aberto.
[015] A figura 2 apresenta uma vista em corte AA, indicado na figura 1 , mostrando o porte parcialmente aberto no ponto de ruptura da linha de enfraquecimento.
[016] A figura 3 apresenta uma vista do pote com detalhe ampliado para exemplificar e indicar a linha de soldagem ultrassónica ente a borda da tampa com o pote.
[017] A figura 4 apresenta uma vista em corte AA, indicado na figura 3, com detalhes ampliados mostrando a argola levantada e a linha de solda ultrassónica e linha de enfraquecimento.
[018] A figura 5 apresenta uma vista em perspectiva do pote fechado.
[019] A figura 6 apresenta uma vista superior.
[020] A figura 7 apresenta uma vista em superior do pote com a tampa parcialmente aberta.
[021 ] A figura 8 apresenta uma vista em perspectiva do pote em uma construção alternativa, mostrando um rebaixo na aba do pote.
[022] A figura 9 apresenta uma vista parcial explodida da tampa e pote, em sua construção alternativa.
[023] A figura 10 apresenta uma vista ampliada mostrando o rebaixo da aba do pote e o ressalto da tampa, antes de ocorrer a solda ultrassónica.
[024] A figura 1 1 apresenta uma vista ampliada mostrando o rebaixo da aba do pote e o ressalto da tampa, após ocorrer a solda ultrassónica. DESCRIÇÃO DETALHADA DA INVENÇÃO
[025] De acordo com as figuras em anexo o presente requerimento é formado por um recipiente (1 ) com borda superior (2) dotado de uma aba (3) lisa e reta que se projeta para fora contornando toda a extensão superior da referida borda superior (2).
[026] A tampa (5) de fechamento em sua parte superior apresenta uma aba (6) que se circunda toda sua extensão e sua largura limitada pelo degrau de rebaixamento (7) onde é projetado um plano rebaixado (8) dotado de um desnível definido por um alojamento rebaixado (9) de posicionamento da argola (10) solidária a superfície do plano rebaixado (8).
[027] Na variante construtiva, a tampa (5) apresenta um ressalto (13) que circunda toda a extensão de sua aba (6), projetada para se encaixar com leve pressão no rebaixo (15) que circunda toda a extensão da aba
(3) do recipiente (1 ).
[028] Nesta construção alternativa, o fechamento do recipiente (1 ) ocorre após o encaixe do ressalto (13) da tampa (5) no rebaixo (15) da aba (3) do pote. Após o encaixe, a superfície externa inferior (14) da tampa (5) fica alinhada sobre a superfície externa superior (16) do pote para o fechamento hermético do recipiente (1 ), por solda ultrassónica, na linha de solda
(4).
[029] O fechamento por solda ultrassónica funde o ressalto (13) no rebaixo (15), fechando hermeticamente o recipiente (1 ) com a tampa (5).
[030] A argola (10) de abertura é fixada no plano rebaixado (8) dentro do alojamento rebaixado (9) e ao ser puxado para cima rompe de forma irreversível a linha de enfraquecimento (12).
[031 ] O posicionamento da argola (10) dentro do alojamento rebaixado (9) possibilita que a referida argola (10) fique nivelada com toda a superfície superior do plano rebaixado (8) facilitando o encaixe do dedo. [032] A parte externa da tampa (5) forma um degrau (1 1 ) que contorna toda a circunferência externa do plano rebaixado (8).
[033] Este degrau (1 1 ) é projetado para se encaixar internamente por leve pressão na borda superior (2) mantendo assim a entrada do recipiente (1 ) fechado.
[034] A linha de enfraquecimento (12) serve de ponto de ruptura para que a tampa (5) possa ser removida quando a argola (10) for puxada para cima.
[035] A linha de enfraquecimento (12) circunda completamente o centro da aba (6) da tampa (5). De modo opcional, a linha de enfraquecimento (12) pode circundar apenas de 70% a 90% o centro da aba (6) da tampa (5), sendo que isto será definido de acordo com a necessidade de fabricação e utilização do produto, não influenciando no escopo do pedido.
[036] O ponto de ruptura ocorre somente na aba (6) próxima ao degrau de rebaixamento (7).
[037] Após o rompimento da linha de enfraquecimento (12) e a completa remoção da tampa (5) a mesma pode ser novamente utilizada para fechar a boca do recipiente (1 ). Este fechamento é possível pois após o rompimento da linha de enfraquecimento (12) uma pequena extensão da aba (6) permanece junto ao degrau de rebaixamento (7), possibilitando que a tampa (5) possa ser novamente encaixada, fechando o recipiente (1 ), porém agora não mais de forma hermética.
[038] O fechamento hermético do recipiente (1 ) ocorre com o alinhamento da aba (3) com a sobreposição do assentamento da aba (6) da tampa (5), após este alinhamento e assentamento a aba (3) e a aba (6) recebe a linha de solda (4) para fechamento por solda ultrassónica que concentram a energia do ultrassom na linha de solda (4). Ou seja, na linha de solda (4) ocorre a fusão entre a aba (3) do pote e aba (6) da tampa (5) para fechamento hermético do recipiente (1 ).
[039] O calor necessário para a selagem por ultrassom é gerado dentro dos materiais somente entre a aba (3) e a aba (6) criando a linha de solda (4) de forma precisa.
[040] A profundidade do derretimento do termoplástico pelo processo de vibração ultrassónica preferencialmente será superficial podendo variar conforme as características do plástico escolhido bem como da espessura da aba (3) e aba (6) escolhida.
[041 ] A linha de solda (4) ocorre em um ponto especifico que circunda toda extensão da referida aba (3) do pote e a aba (6) da tampa (5), para que o recipiente (1 ) seja fechado hermeticamente.
[042] A Abertura do recipiente (1 ) ocorre de forma manual com a ação manual quando a argola (10) é puxada para cima, neste momento no ponto de ruptura da linha de enfraquecimento (12) que ocorre somente na aba (6) posicionada na parte superior é dividida em duas partes ficando uma parte da aba (6) circundando toda a circunferência da tampa (5) a outra parte permanece soldada na aba (3) do recipiente (1 ).
[043] O fechamento após a abertura ocorre no encaixe da tampa (5) no recipiente (1 ) neste momento a parte da aba (6) que ficou soldada na aba (3) volta a se alinhar com a borda (6) da tampa (5).
[044] O formato da tampa (5) do recipiente (1 ) e a forma e a linha de soldagem ultrassónica possibilitou se criar um pote fechado hermeticamente que posteriormente a sua abertura possa ser usado novamente várias vezes, resolvendo os problemas anteriormente destacados obtendo assim rapidez no processo produtivo, redução de custos e redução no descarte partes anteriormente utilizadas como lacres de vedação hermética.
