Description
本發明係與發泡容器有關，詳而言之，係指一種製造發泡容器之射押出製法。 The present invention relates to a foamed container, and more specifically to a method of producing a foamed container by injection.
按，市面上承裝飲料之容器須具有隔絶温度傳導之效果，故常見飲料杯以發泡材料製成，以提供保温或保持冰涼之效果。 According to the container, the container for beverages on the market must have the effect of insulating the temperature, so the common beverage cup is made of foamed material to provide insulation or keep cool.
請參閱第五、六圖，係習知一種以押出方式製造發泡容器之製法，其包含以下步驟：步驟(a)、形成平板狀發泡材60：利用押出機將已發泡材料押出並滾壓成平板狀發泡材60；步驟(b)、貼膜：於該平板狀發泡材60之表面貼上一層膠膜61；步驟(c)、將平板狀發泡材60置入真空成型機；步驟(d)、加熱平板狀發泡材60並將發泡材壓成發泡容器半成品62：將該發泡材60加熱使其軟化容易塑形，接著以模具70之公模71及母模72將該發泡材60壓出多個發泡容器半成品62；最後，步驟(e)、裁切成發泡容器成品63：利用裁切刀具80自該平板狀發泡材60上裁切該等已塑形之半成品，即完成複數發泡容器成品63。 Please refer to the fifth and sixth figures, which are a method for manufacturing a foamed container by extrusion, which comprises the following steps: Step (a), forming a flat foam material 60: extruding the foamed material by using an extruder Rolling into a flat foam material 60; step (b), film: applying a film 61 on the surface of the flat foam material 60; and step (c), placing the flat foam material 60 into vacuum forming Step (d), heating the flat foam material 60 and pressing the foam material into the foam container semi-finished product 62: heating the foam material 60 to soften and easily shape it, followed by the male mold 71 of the mold 70 and The master mold 72 presses the foamed material 60 out of the plurality of foamed container semi-finished products 62; finally, the step (e), cutting into the foamed container finished product 63: cutting from the flat foaming material 60 by the cutting tool 80 The finished semi-finished product is cut, that is, the finished foaming container finished product 63 is completed.
上述習知發泡容器之製法，係利用押出機將已發泡材料押出並滾壓成平板狀發泡材60，於平板狀發泡材60的表面貼設膠膜61，再將平板狀發泡材60置入真空成型機內，加熱發 泡材60並將發泡材60壓成發泡容器半成品62，再經由裁切成所需之發泡容器成品63；該膠膜係為製成品之標籤。製成後，剩餘發泡材60則成為廢料64。依上述製法，原物料中大約只有67%製成發泡容器成品63，其餘的33%則成為廢料，造成發泡材料上的浪費以及製造成本提升。 The above-mentioned conventional foaming container is produced by extruding and rolling the foamed material into a flat foaming material 60 by using an extruder, attaching a film 61 to the surface of the flat foaming material 60, and then forming a flat foaming material. 60 placed in a vacuum forming machine, heated The foam material 60 and the foamed material 60 are pressed into a foamed container semi-finished product 62, and then cut into a desired foamed container finished product 63; the adhesive film is a label of the finished product. After the production, the remaining foamed material 60 becomes the waste material 64. According to the above method, only about 67% of the original material is made into the finished container 63 of the foamed container, and the remaining 33% becomes waste, which causes waste on the foamed material and an increase in manufacturing cost.
習知另一種發泡容器之製法，是利用塑膠射出的方式，如第七圖所示，於模具90合模時，以射料管92將發泡材料95自模具之狹小之射料口93以高速高壓之方式射入模穴94內，以成型發泡容器。於射出成型之製法中，為了將模穴94內之氣體擠出模穴94，故須以高壓高速之方式射料。惟採用此種製法所製成之發泡容器係形成業界俗稱之微細發泡，亦即，於高速高壓射出過程中，發泡材料95內之氣泡會被擠壓、破壞，造成發泡材料95內之氣泡小，製成品之發泡倍率低於5倍，導致發泡容器之絶緣效果(保温、保冷)不佳。 Another method for preparing a foaming container is to use a plastic injection method. As shown in the seventh figure, when the mold 90 is closed, the foaming material 95 is used to feed the foaming material 95 from the narrow injection port of the mold. It is injected into the cavity 94 in a high speed and high pressure manner to form a foamed container. In the injection molding method, in order to extrude the gas in the cavity 94 from the cavity 94, it is necessary to shoot at a high pressure and high speed. However, the foamed container produced by such a method is formed into a micro-foam which is commonly known in the industry, that is, in a high-speed high-pressure injection process, bubbles in the foamed material 95 are crushed and destroyed, resulting in a foamed material 95. The bubble inside is small, and the foaming ratio of the finished product is less than 5 times, resulting in poor insulation effect (insulation, cold preservation) of the foaming container.
針對上述二種先前技術製法之弊端，實有加以解決之必要。 In view of the shortcomings of the above two prior art methods, it is necessary to solve them.
本發明之主要目的在於提供一種發泡容器之射押出製法，將發泡材料以射押出發泡之方式製作發泡容器，以減少廢料。 The main object of the present invention is to provide a method for shooting and extruding a foamed container, which is formed by foaming a foamed material to reduce waste.
