Description
MEMÕRIA DESCRITIVA
São já conhecidas muitas embalagens de matéria plástica que compreendem um receptáculo rígido que tem ou não alvéolos onde se colocam o produto ou produtos e é fechado com uma folha pelável, quer dizer que pode ser descolada a pouco e pouco por meio de um esforço de tracção exercido sobre uma parte da sua periferia.
Nas embalagens deste tipo, o receptáculo é de cloreto de polivinilo (PVC) e a folha que o fecha é de polietileno, cuja soldadura sobre o PVC permite o arrancamento mas que é maleável.
Como esta matéria não tem rigidez, estas embalagens protegem mal os produtos que contêm, e até agora não era possível realizar uma embalagem que tivesse o fundo e a tampa rígidos de PVC, que protegesse assim de maneira eficaz os produtos ou artigos embalados contra os contactos, choques ou pressões e cuja tampa pudesse ser separada do fundo por descolagem progressiva, isto é, uma tampa pelável, devido ao facto de as soldaduras de PVC sobre PVC não serem separáveis.
objecto da invenção é remediar esta carência, realizando essa embalagem completamente rígida que tem também uma tampa rígida pelável.
Para este fim, a invenção tem como objecto uma embaiag^m do tipo que compreende um fundo rígido de PVC, fechado na sua parte superior por uma parede pelável, caractetizada pelo facto de a tampa ser geralmente de cloreto de polivinilo rígido, tendo pelo menos ura, o fundo ou a tampa, na face no interior da embalagem uma camada delgada de polietileno de qualidade pelável, sendo a rigidez do fundo maior que a da tampa, estando esta fixada no fundo por meio de faixa de soldadura periférica que tem pelo menos uma zona de enfranquecimento.
Preferivelmente, o fundo e a tampa são formados por una folha de PVC revestida, depois de ter sido formada, com uma camada de polietileno sobre a qual se aplica uma película de polietileno de qualidade pelável.

GB/1960
3A invenção tem também como objecto ura tabuleiro-expositor que constitui uma embalagem rígida, caracterizado por compreender ura fundo e uma tampa rígidos de PVC, um dos quais, pelo menos, tem na face interior uma camada delgada de polietileno de qualidade pelável, tendo o fundo alvéolos e uraa rigidez maior que a da tampa, estando esta fixada no fundo por meio de uma faixa de soldadura periférica que tem pelo menos, uma zona de enfraquecimento.
Embora o tabuleiro-expositor de acordo com a invenção possa ser utilizado para todas as espécies de produtos manufacturados, vai ser descrito adiante, como exemplo, na sua aplicação a produtos alimentares e mais particularmente para queijinhos.
De acordo com outra caracteristica da invenção, o fundo e a tampa compreendem ambos um rebordo periférico exterior plano que tem duas orelhas opostas salientes para o exterior e com forma e dimensões iguais, estando os referidos rebordos, sobrepostos, soldados um ao outro por meio de uma linha de soldadura periférica na qual os referidos pontos de enfraquecimento são estreitamente contíguos à base das referidas orelhas.
A descrição que se segue, feita com referência aos desenhos anexos como exemplo não limitativo, permitirá compreender bem a maneira como a invenção pode ser aplicada.
A figura 1 é uma vista em alçado lateral esquemático em corte longitudinal de um tabuleiro-expositor, de acordo com a invenção.
A figura 2 é uma vista de cima em planta.
A figura 3 é uraa vista esquemática parcial em corte pela linha III-III da figura 2.
A figura 4 é uraa vista esquemática parcial era corte pela linha IV-IV da figura 2.
A figura 5 é uma vista parcial em escala muito ampliada que mostra a sobreposição das diversas camadas de matérias do fundo e/ou da tampa.
Com referência ao desenho, o tabuleiro-expositor de acordo com a invenção compreende um fundo 1 e uraa tampa 2 que têm am66.412
GB/19Ó0
-4bos um rebordo periférico plano 3, 3' que se prolonga para o ex terior num plano paralelo ao plano longitudinal mediano X-X do conjunto.
Segundo a forma de realização representada, o fundo 1 é de material compósito que compreende uma folha 10 de cloreto de polivinilo (PVC) de qualidade alimentar, opaca, colorida ou não, formada a quente por um processo conhecido de maneira a ter alvéolos 4 destinados a conter por exemplo queijinhos (bocados), e revestida a seguir com uma camada mais delgada 11 de polietileno de qualidade alimentar sobre a qual se aplica finalmente, por laminagem sob pressão, uma película delgada 12 de polietileno de qualidade pelável.
fundo tem convenientemente um canal periférico 5» com secção em U ou análoga, convenientemente formado pelo mesmo processo que os alvéolos 4 e ao mesmo tempo que estes.
Conforme está representado no desenho, o canal 5 θ imediatamente contíguo ao rebordo periférico 3' do fundo, para o interior era relação do referido rebordo.
Λ tampa 2 é oca e forma uma campânula, que é feita também do mesmo material compósito que o fundo 1, mas transparente: a sua abertura é delimitada pelo rebordo 3, cuja forma e dimensões são iguais às do rebordo 3' do fundo 1.
Os rebordos 3 θ 3’ têm ambos duas orelhas 6, 6' opostas que se prolongam para o exterior no plano dos rebordos 3? 3' respectivamente.
Segundo o exemplo representado, as orelhas 6, 6' tem forma arredondada, mas a sua forma pode ser alongada, rectangular ou outra.
Analogamente, no que diz respeito aos alvéolos 4, compreende-se que a sua forma e número podem ser diferentes do exemplo representado.
Os rebordos 35 3' são colados ou soldados, preferivelmente por alta frequência ou outro processo apropriado não térmico, ao longo de uma faixa contínua 7 sobre os rebordos, com largura constante em toda a periferia da embalagem excepto ao nível das orelhas 6, 6' onde esta soldadura das películas de polietileno εε 412
C-P/196C
ζ peláveis urra com a outra tãm uma parte enfraquecida constituída por uma porção 9 com largura bastante menor, deixando subsistir uma porção notável das orelhas 6, 6' não soldadas conjuntamente z z e que permite afasta-las e pegar-lhes, conforme esta representado na figura 3, a fim de exercer nelas um esforço de tracção em sentido inverso ao nível da zona enfraquecida 9 da soldadura 7. Desta maneira, é possível abrir facilmente o tabuleiro-expositor por descolagem progressiva da tampa.
A
De maneira vantajosa, a tampa 2 tem pelo menos uma saliência voltada para o interior, como representado em 9, com a forma de pirâmide ou cone, para juntar uma possível condensação na face interior da tampa.
A tampa, como não tem meios análogos ao canal 5 do fundo, * f e menos rigioa que este, o que facilita a descolagem quando se procede a abertura do tabuleiro-apresentador. Alem disso, a sua espessura e menor que a do tabuleiro, sendo a proporção das espessuras tampa/tabule iro convenientemente de aproximadamente 7:1C, por exemplo 7 para a tampa e õCO ^um para o fundo.
A rigidez do tabuleiro-expositor de acordo com a invenção permite a embalagem de produtos frágeis, por exemple cueijos, e a sua sobreposição sem perigo de deterioração.
tabuleiro-expositor realizado desta maneira é rígido e impermeável. Por este facto, é preferivelmente cheio com um gas inerte no momento da soldadura, o que proporciona uma ampliação da duração de conservação dos produtos que contém.
Compreende-se, obviam.ente, que a invenção não está limita da a forma representada em planta como exemplo na figura 2, po dendo esta forma ser circular, oval ou outra. Além disso, podem acrescentar-se no tabuleiro motivos decorativos ou publici tários.
