Description

1
Изобретение относитс  к упаковке жидких продуктов, а именно к контейнеру дл  жидкости, например молока.
Известен контейнер дл  жидкости, имеющий герметичный многослойный шов.
Целью изобретени   вл етс  удобство открывани  контейнера. Дл  этого шов выполнен с бороздкой с возможностью разрыва его по последней и имеет над бороздкой толщину превышающую сумму
толщин слоев, а толщина бороздки меньше , чем первоначальна  толщина одного из слоев.
На фиг. 1 изображен герметичный шов из четырех слоев, разрез; на фиг. 2 сварочные зажимы, разрез; на фиг. . 3 форма головки контейнера с одним герметичным швом; на фиг. 4 - то же, с двум  герметичными швами.
Предлагаемый контейнер дл  жидкости имеет герметичный многослойный шов 1, выполненный с бороздкой 2 с возможностью разрыва его по последней.
Часть 3 шва над бороздкой имеет толщину , превышающую сумму толщин слоев 4-7. При этом толщина бороздки 2 меньше , чем первоначальна  толщина одного из слоев.
Шов выполнен из полистиролового пенопласта ТОЛ1Щ1НОЙ каждый примерно 2.5м и плотностью приблизительно 40 кг/м ; Слои 4-7 свариваютс  вместе с помощью нагреваемых; сварочных зажимов 8 и 9, образу  герметичный многослойный шов 1
Зажимы нагреваютс  до температуры
примерно на 20 С выще точки разм гчени  пенопласта, при этом зажим 9 имеет пр моугольный выступ 10 с закругленными углами дл  возможности предотвращени  трени  в слое пенопласта, примыкающем к нему, при сжатии слоев.
Кроме того, сварочные зажимы имеют плоские поверхности 11 и 12, обращенные одна к другой.
При образовании герметичного шва зажимы 8 и 9, между которыми расположены слои пенопласта, движутс  один навстречу другому так, что слои сжимаютс  приблизительно до 20% их первоначальной толщины только в том месте, где в зажиме имеетс  выступ 10, в результате чего слои сжимаютс  менее чем до 2 удельна  поверхность давлени  на них превышает 200 кг/см . При этом высота выступа 10 равна или меньше толщины сло , а высота плоских поверхностей 11 и 12 превышает сумму тол- вдин слоев.. Предпочтительное врем , в течение которого слои Сжимаютс , состал ет. 2-10 сек. При этом при сжатии воздуха в  чейках сло  в месте выступа в плоскост х последних, обращенных друг к другу, температура более высока , вследствие чего бороздка 2 шва 1 легко разрываетс . Головка контейнера 13 может быть вЫ полнена из одного сло  пенопласта и состоит из створок, сваренных по У-образног му контуру. В фальцованных част х 14 и 15 соедин ютс  только по две толщины сло , и герметичные швы не имеют бороздки.. В третьей ветви У-образного контура соеди шютс  четыре сло  пено- .пластовых листов, при этом герметичный шов имеет, бороздку 16, а часть 17 - то шину, превышающую сумму толщин слоев. При этом часть 1 служит как дл  захва та контейнера, так и дл  разрыва его вдоль бороздки 16. Кроме того, фальцованные части соеди н ютс  в виде взаимно перпендикул рных плоскостей 18(см фиг, 4), а герметичный шов выполн етс  в их верхней части во всех четырех или только в двух плоскост х с образованием бороздок 19 и вы тупающей, над ним части 2О. При этом .свариваютс  два сло , и при сварке выступ 10 выходит над поверхностью 11 меньше f чем на ,2О% толщины двух слоев Герметичный шов может быть также выполнен из других материалов, например из четырех слоев м гкого полиэтилена с fзакрытыми  чейками толщиной 2,5мм,с плотностью примерно 45 кг/м и степенью лоперечного св зывани , при которой; 18,6% веса раствор етс  в кип щей кисло-j |те, или двух слоев поперечно св занного ;полипропилена с закрытыми  чейками с плотностью 70 кг/м , степенью попереч;ного св зывани  32,7%, с растворением в кип щей кислоте и йри толцщце 2 мм. 1 Другие пеноплйсты также можно сва|ривать герметичным щврм, содержащим бороздку с условием их термопластичности| и применением нагрева и давлени . При этом предпочтительными материалами  вл ютс  полистирол, полистирол - каучуковые .соединени , поливинилхлорид, сополи- мерЬ виниловых соединений, полирлефины I и соединени  акрилонитрил-бутадиен-стирола и другие - полимеры и сополимеры, полученные из мономеров общей формулы Н или СН„ , а хСу, где X . .у - н.с.е, с,-.н-, соон, соонсн |/- IIDOd i, , В сополимере может быть выстроен диолефин, а также могут использоватьс  модификации из смеси этих полимеров. В контейнерах могут хранитьс  не толь ко молоко, но и другие вещества, не pea:гирующие с пеной, пластификатором,, стабилизатором , образователем пены или кра-, сител ми примен емь1х материалов. ПРЕДМЕТ ИЗОБРЕТЕНИЯ . , Контейнер дл  жидкости, например моjTOKaj имеющий герметичный многослой- ный шов,о т л и ч а   тем, что, с целью удобства открывани  контейнера , щов выполнен с бороздкой с возможностью разрыва его по последней и (имеет над бороздкой толщину, превыща ющую сумму толщин слоев, а толщина |бороздки меньше, чем первоначальна  тол|щина одного из слоев ,
