紙塑蓋體及其成形裝置 Paper plastic cover body and forming device thereof

本發明有關於一種紙塑蓋體，特別是關於一種在具有與杯身扣合處扣接的一次成型負角度部之紙塑蓋體及其製造方法以及裝置。 BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a paper-plastic cover, and more particularly to a paper-plastic cover having a primary-formed negative angle portion that is fastened to a fastening portion with a cup body, a method of manufacturing the same, and a device.

紙杯與紙碗是一種在目前日常生活中使用量極大之拋棄式產品，故綜合考量製造素材成本以及製品相異之需求強度之下，製造者已有多種不同相對應之製作方式。 Paper cups and paper bowls are a kind of disposable products that are used in daily life. Therefore, under the comprehensive consideration of the cost of manufacturing materials and the demand intensity of different products, manufacturers have a variety of different corresponding production methods.

但若須追求穩固質感之造型或是厚度相對高之紙製產品時，則需要將紙漿積疊至有一定厚度後才能進行塑形，然而，若按照傳統壓製日常生活中常見厚度較薄之免洗紙杯紙碗之方法以對具有一定厚度之紙漿層進行壓製時，則相當容易發生壓製後積漿呈現被擠出之凸邊或是不規則之皺褶表面，對於產品之美觀以及結構堅固程度皆有影響。 However, if you want to pursue a stable texture or a relatively high-thickness paper product, you need to stack the pulp to a certain thickness before shaping. However, if you press the traditional thinner thickness in daily life, When the method of washing the paper cup is to press the pulp layer having a certain thickness, it is quite easy to produce the extruded embossed or irregular wrinkled surface after pressing, for the beauty of the product and the structural firmness. All have an impact.

另外，對於上述等對厚度有要求之紙漿產品，近年則發展出一種適宜的紙塑成型之製程方法(或稱紙漿模壓成形法)，然而，對於日常生活中最常用的杯蓋而言，這些杯蓋在其邊緣上以與杯身壓合之扣合處部分，大多數具有向內側浮凸或倒鉤部分等等，用以使扣合能夠更加緊密，然而目前以紙塑成型製造杯蓋，該些內側浮凸或倒鉤部分皆係以成形 完後之成品再進行局部滾壓二次加工的方式完成。 In addition, in recent years, a pulp product having a thickness requirement has been developed, and in recent years, a suitable paper-forming process (or a press molding method) has been developed. However, for the most commonly used cup lids in daily life, these are The cup cover has a snap-fit portion on its edge that is pressed against the cup body, most of which has an inwardly convex or barbed portion, etc., to make the fastening more compact, but currently the cup cover is made by paper molding. The inner embossing or barb portions are formed After the finished product is finished by partial rolling secondary processing.

然而，透過該再滾壓方式完成之杯蓋成品須浪費時間成本進行再加工，而滾壓亦有較高可能造成成品瑕疵或不美觀問題。 However, the finished cup cover finished by the re-rolling method is costly to be reworked, and the high rolling pressure may cause defective defects or unsightly problems.

有鑑於先前技術之問題，本發明之目的即是以一體成型方式製成紙塑蓋體，以降低生產時間與生產成本。 In view of the problems of the prior art, the object of the present invention is to form a paper-plastic cover in an integrally formed manner to reduce production time and production cost.

根據發明之目的，係提供一種紙塑蓋體該紙塑蓋體設有一中央部及沿該中央部之邊緣上設有一邊緣部，該邊緣部係於該紙塑蓋體與外部容器扣合時將外部容器的容器外壁上緣納入其中，並且該邊緣部夾持外部容器的容器外壁邊緣。 According to an object of the invention, a paper-plastic cover body is provided, the paper-plastic cover body is provided with a central portion and an edge portion is provided along an edge of the central portion, the edge portion being attached when the paper-plastic cover body is engaged with the outer container The upper edge of the outer wall of the outer container is incorporated therein, and the edge portion holds the outer wall edge of the outer container.

再者，該邊緣部設有與外部容器的容器外壁邊緣下方搭接之一扣合部，且該扣合部係與該中央部及邊緣部整體以一次成型方式所製成的，該扣合部之作用為使該紙塑蓋體與外部容器扣合時，不僅以該邊緣部夾持外部容器的容器外壁上緣，更能以該扣合部與外部容器邊緣之突出部扣接咬合，藉以讓紙塑蓋體能夠更穩固地與外部容器結合。 Furthermore, the edge portion is provided with a fastening portion that is overlapped with the outer edge of the outer wall of the container of the outer container, and the fastening portion is integrally formed with the central portion and the edge portion in a single molding manner. When the paper plastic cover body is engaged with the outer container, the upper edge of the outer wall of the outer container is not only clamped by the edge portion, but also the engaging portion of the outer container edge is buckled and engaged by the fastening portion. This allows the paper-plastic cover to be more firmly bonded to the outer container.

而為了製造上述紙塑蓋體，本發明係提供一種紙塑蓋體之成型裝置，其包括一蓋體成型第一模具及一蓋體成型第二模具，其中，該蓋體成型第一模具內包含有一第一成型單元，該第一成型單元設有一中央成型部，係用以成型前述對應之該紙塑蓋體的該中央部，且該第一成型單元上更設置有一邊緣成型部，以成型對應該紙塑蓋體之該邊緣部；再者，該邊緣成型部相對於該中央成型部之外邊緣上負角度地 向內凹設有一扣合成型部，該扣合成型部係用以成型對應該紙塑蓋體上負角度的的該扣合部。而該蓋體成型第二模具設有一第二成型單元，以成型對應於該第二成型單元之紙塑蓋體完成品的外側之形狀。 In order to manufacture the above-mentioned paper-plastic cover body, the present invention provides a paper-plastic cover body molding apparatus, which comprises a cover-molded first mold and a cover-formed second mold, wherein the cover body is molded into the first mold. The first molding unit is provided with a central molding portion for molding the central portion of the corresponding paper-plastic cover body, and the first molding unit is further provided with an edge molding portion for Forming the edge portion corresponding to the paper-plastic cover; further, the edge forming portion is at a negative angle with respect to an outer edge of the central molding portion The inner concave portion is provided with a buckle forming portion for forming the engaging portion corresponding to a negative angle on the paper plastic cover. And the cover molding second mold is provided with a second molding unit to shape the outer side of the finished product of the paper-plastic cover corresponding to the second molding unit.

據上所述，本發明之紙塑蓋體之製造流程與傳統的紙塑產品於製造流程上大致相同。但由於紙漿熱壓成型時，仍具有一定的彈性，令該紙塑蓋體於脫模的過程中，該紙塑蓋體上之該扣合部將會稍微變型以脫離該扣合成型部，但在脫離後該扣合部形狀，仍會與原先塑型之扣合成型部的形狀相似，才得以使該扣合部和外部容器接合時，該扣合部能扣接在外部容器杯緣向外之突出部，並能符合紙塑蓋體與外部容器結合所應需要符合之產品標準。 According to the above, the manufacturing process of the paper-plastic cover of the present invention is substantially the same as that of the conventional paper-plastic product. However, since the pulp has a certain elasticity during hot press forming, the fastening portion of the paper plastic cover body is slightly deformed to be detached from the buckle composite portion during the demolding process. However, after the detachment, the shape of the fastening portion is still similar to the shape of the buckled synthetic portion of the original molding, so that when the fastening portion and the outer container are engaged, the fastening portion can be fastened to the outer container cup edge. The outward protruding portion can meet the product standard that should be met when the paper-plastic cover is combined with the outer container.

At this time, the rough embryo of the paper-plastic cover body 1 formed by the pressed pulp should be sucked by the cover body to form the second mold. Taking out and completely detaching the cover body to form the first mold 22 and the filter net 226 closely attached thereto, and the fastening portion 14 of the paper plastic cover body 1 has paper elasticity, and it can be seen from the figure that it is completely detached from the cover body. After the first mold is formed, the deformed portion originally formed by the engaging portion 14 will slightly recover, and the degree of recovery will make the shape of the engaging portion 14 substantially the same as the shape of the buckle-shaped portion 2203, but may be somewhat different. Extrusion deformation or the portion to be cut, but the situation will still increase the strength of the fastening portion 14 and the protruding portion of the outer container after the calculation of the process of the present invention, and it is known that the present invention may occur in an actual process. This situation will not affect the effectiveness of the present invention in solving problems.
