本文中描述元件名稱的「上方」、「下方」、「左側」、「右側」、「側邊」之用語，是用以對照並說明各部件的相對位置，並非用以限定本發明的範圍。The terms "upper", "lower", "left", "right" and "side" used to describe component names in this article are used to compare and illustrate the relative positions of each component, and are not intended to limit the scope of the present invention.
第1圖為本發明之一實施例的咖啡濾掛結構100開封前的平面圖。如第1圖所示，咖啡濾掛結構100包括濾袋200與掛耳部300。濾袋200由過濾片材202形成，具有多個濾孔250。作為過濾片材202，可以使用由塑膠母粒經過熔噴製程所製得的不織布。在此實施例中，塑膠母粒的材質可以是聚乙烯、聚丙烯、聚酯、聚醯胺、聚氨酯、甲基丙烯酸甲酯或由上述材料任選兩種所形成的共聚物或共混物。Figure 1 is a plan view of the coffee
掛耳部300由塑膠片經過衝壓製程所形成。此塑膠片是塑膠母粒經過發泡成型製程製得的塑膠片。在此實施例中，塑膠母粒的材質可以是聚乙烯、聚丙烯、聚酯、聚醯胺、聚氨酯、甲基丙烯酸甲酯或由上述材料任選兩種所形成的共聚物或共混物。掛耳部300亦可以是延壓薄片、織布片材或不織布片材。由於掛耳部300是一種塑膠片片、延壓薄片、織布片材或不織布片材，遇水之後不會影響支撐強度，因此不需在掛耳部300的表面塗布濕強劑。The
在此實施例中，濾袋200與掛耳部300選用同一材質。即，當濾袋200使用聚乙烯製成不織布，則掛耳部300使用聚乙烯製成的塑膠片、延壓薄片、織布片材或不織布片材。由於濾袋200與掛耳部300使用同一材質，在丟棄使用完的咖啡濾掛時，可以容易地進行回收。In this embodiment, the
如第1圖所示，位於濾袋200一側的一個掛耳部300包括：支撐部310、兩個跨架部320、多條壓折線330-1、壓折線330-2、壓折線330-3、多條切斷線340。As shown in Figure 1, an
支撐部310具有開口支撐片312、底部支撐片314、中央支撐片316與位於左右兩側的側邊支撐片318。中央支撐片316與兩側的側邊支撐片318連接開口支撐片312與底部支撐片314。由於濾袋200與掛耳部300使用同一材質，將濾袋200與掛耳部300接合時不需使用黏著劑，可以使用超音波熔接或熱壓貼合處理將支撐部310與濾袋200接合。The
兩個跨架部320分別位於掛耳部300的左右兩側。各跨架部320分別具有連接部322與凸部324。各跨架部320透過連接部322與其中一側的側邊支撐片318連接。各跨架部320在靠近中央支撐片316的一側向底部支撐片314形成凸部324。The two
在開口支撐片312中央設置縱向的壓折線330-1。在開口支撐片312左右兩側設置較壓折線330-1短的縱向的壓折線330-2。在各連接部322設置延伸至側邊支撐片318的斜向的壓折線330-3。壓折線330-1、壓折線330-2、壓折線330-3用以引導開口支撐片312與連接部322彎折成預期的形狀。A longitudinal folding line 330-1 is provided in the center of the
在跨架部320緊靠開口支撐片312、底部支撐片314以及中央支撐片316的邊界設置切斷線340。設置切斷線340用以使跨架部320與開口支撐片312、底部支撐片314以及中央支撐片316分離。由於在進行超音波熔接時，僅將支撐部310與濾袋200接合，因此跨架部320也會與濾袋200分離。A
在濾袋200靠近開口支撐片312的一側設置開封線260。開封線260在常態下為封閉狀態，以避免咖啡粉溢出，在使用時則可以輕易地撕開。An
第2圖為本發明之一實施例的咖啡濾掛結構100展開後的立體圖。如第2圖所示，展開後的濾袋200具有開口210、袋壁220、袋狀底部230、容室240與多個濾孔250。開口210位於濾袋200的上方。由袋壁220與袋狀底部230共同定義出容室240，並且開口210與容室240連通。在此實施例中，袋壁220為矩形，並形成方形的袋狀底部230。Figure 2 is an expanded perspective view of the coffee
支撐部310與袋壁220接合，支撐部310用以支撐並維持濾袋200的形狀。由於掛耳部300由具有形狀記憶特性的塑膠片形成，濾袋200展開後，沿著開口210設置的開口支撐片312可以維持開口210展開的狀態，而沿著袋狀底部230設置的底部支撐片314可以維持袋狀底部230展開的狀態。中央支撐片316與側邊支撐片318用以支撐並連接開口支撐片312與底部支撐片314。The
跨架部320分別位於掛耳部300的左右兩側。以左側的跨架部320為例，跨架部320透過連接部322與左側的側邊支撐片318連接。沿著左側連接部322的壓折線330-3彎折左側跨架部320後，左側跨架部320可以向左側展開，並與袋壁220分離。右側的跨架部320則可以向右側展開，並與袋壁220分離。The bridging
在此實施例中，用於製成掛耳部300的塑膠片可以具有形狀記憶特性。如此一來，沿著壓折線330-1、壓折線330-2、壓折線330-3可以彎折開口支撐片312以展開濾袋200的開口210，並彎折連接部322以展開跨架部320。而這些沿著壓折線330-1、壓折線330-2、壓折線330-3彎折的部分可以維持彎折後的形狀。In this embodiment, the plastic sheet used to make the
第3圖至第5圖為本發明之一實施例的咖啡濾掛結構100使用說明圖。在使用咖啡濾掛結構100時，先撕開開封線260，如第3圖所示，用手指捏住兩側的側邊支撐片318，兩側同時向濾袋200中央適當擠壓。經由壓折線330-1、壓折線330-2的引導，可以展開濾袋200，應由壓折線330-3的引導，可以展開跨架部320。如第4圖所示，依照杯口大小調整跨架部320展開程度，再如第5圖將咖啡濾掛結構100跨架於杯緣400。接下來從開口210加水至濾袋200內，便可沖泡容室240內填充的萃取材料，例如咖啡。Figures 3 to 5 are diagrams illustrating the use of the coffee
如第5圖所示，跨架部320的凸部324遠離中央支撐片316的一側用以掛在杯緣400的外側，使得咖啡濾掛結構100可以跨架在杯緣400上。如此一來，即使注入較多水使液面接近杯緣400，由於袋狀底部230高於杯緣400，袋狀底部230而不會碰到液面。As shown in FIG. 5 , the side of the protruding
第6圖為本發明之一實施例的咖啡濾掛結構100的製造用片材的俯視圖。第7圖為本發明之一實施例的咖啡濾掛結構100的製造方法的說明圖。Figure 6 is a top view of a manufacturing sheet of the coffee
如第6圖所示，咖啡濾掛結構100主要包括過濾片材202與掛耳部300。先將掛耳部300靠近底部支撐片314側間隔後彼此相對，再將底部相對的一對掛耳部300間隔排列在長條形的過濾片材202上。以超音波熔接將過濾片材202與掛耳部300的支撐部310進行接合。As shown in FIG. 6 , the coffee
再如第7圖所示，將過濾片材202的長邊重合並對折。在靠近開口支撐片312一側的過濾片材202上，設置開封線260。以濾袋200的寬度d間隔在過濾片材202的短邊方向上重複進行熔接熔斷，並在此期間一邊填充一袋份量的咖啡粉等萃取材料，即可獲得本發明之一實施例咖啡濾掛結構100。As shown in Figure 7, the long sides of the
如上述，本發明之一實施例的咖啡濾掛結構100的濾袋200是將過濾片材202從中間對折而成，濾袋200沒有其他的反折結構。因此，使用具有形狀記憶特性的發泡塑膠片製成掛耳部300，可以有效地維持濾袋200展開後開口210以及容室240的形狀。As mentioned above, the
第8圖為本發明之另一實施例的咖啡濾掛結構100B開封前的平面圖。如第8圖所示，咖啡濾掛結構100B的袋壁220B是五角形，並形成錐形的袋狀底部230B。在此實施例中，壓折線330B-1、壓折線330B-2、壓折線330B-3是縱向的，壓折線330B-4是斜向的。Figure 8 is a plan view of the coffee
第9圖為本發明之另一實施例的咖啡濾掛結構100B使用示意圖。如第9圖所示，將咖啡濾掛結構100B經由跨架部320B跨架在杯緣400上後，五角形的袋壁220B可以使咖啡透過錐形的袋狀底部230B兩個邊線相交的尖端濾出。由於袋狀底部230B的底部面積小於頂部，沖泡時咖啡液體會較快落入杯中，使熱水與研磨好的咖啡粉接觸的時間縮短，達到短時間內迅速萃取咖啡的目的，並使咖啡口感上較為清爽。Figure 9 is a schematic diagram of the use of the coffee
第10圖為本發明之一實施例的咖啡濾掛結構100C的製造用片材的俯視圖。如第10圖所示，在過濾片材202C上掛耳部300C支撐部310C中央處，也就是一對跨架部320C與另一對跨架部320C之間處，形成多條肋狀底部支撐片314C-1以及多個空洞314C-2。在製成掛耳部300C的塑膠片經過衝壓製程時將空洞314C-2的塑膠片移除，形成出空洞314C-2。再以超音波熔接將支撐部310C與過濾片材202C接合。Figure 10 is a top view of a sheet for manufacturing a coffee
第11圖為本發明之一實施例的咖啡濾掛結構100C使用說明圖。如第11圖所示，將咖啡濾掛結構100C經由跨架部320C跨架在杯緣400上後，咖啡可以經由袋狀底部230C上的肋狀底部支撐片314C-1的空洞314C-2濾出。由於方形的袋狀底部230C角落部分的咖啡粉時常未充分浸水，透過肋狀底部支撐片314C-1形成的空洞314C-2可以將水流平均引導至整個袋狀底部230C，使角落的咖啡粉充分浸水。並且肋狀底部支撐片314C-1也能為袋狀底部230C提供支撐力，並維持袋狀底部230C的展開形狀。Figure 11 is a diagram illustrating the use of the coffee
第12圖為本發明之又一實施例的咖啡濾掛結構100D開封前的平面圖。如第12圖所示，跨架部320D-1分別位於掛耳部300D的左右兩側。在支撐部310D上設置壓折線330D-1、330D-2、330D-3。以左側的跨架部320D-1為例，跨架部320D-1透過連接部322D與中央支撐片316D連接。沿著左側連接部322D的壓折線330D-3彎折左側跨架部320D-1後，左側跨架部320D-1可以向右側展開，並與袋壁220D分離。即，左右兩側跨架部320D-1可以向中央支撐片316D的方向展開。Figure 12 is a plan view of the coffee
又如第12圖所示，可以依需求在跨架部320D形成空洞320D-2。在製成掛耳部300D的塑膠片經過衝壓製程時將空洞320D-2的塑膠片移除，形成出空洞320D-2。再以超音波熔接將支撐部310D與濾袋200接合。跨架部320D的空洞320D-2可以減輕加工完成的咖啡濾掛結構100D的重量。As shown in FIG. 12 , a
第13圖為本發明之又一實施例的咖啡濾掛結構100D使用說明圖。如第13圖所示，將咖啡濾掛結構100D經由跨架部320D-1跨架在杯緣400上後，咖啡可以經由袋狀底部230D濾出。在此實施例中，由於左右兩側跨架部320D-1向中央支撐片316D的方向展開，較寬的中央支撐片316D擋住從袋壁220D中央濾出的水，因此能引導水流向兩側流出，進而使兩側的咖啡粉充分浸水。並且中央支撐片316D也能為袋壁220D提供縱向的支撐力。Figure 13 is a diagram illustrating the use of the coffee
綜上所述，本發明之一些實施例所提出的咖啡濾掛結構，濾袋與掛耳部選用同一材質，可以使用超音波熔接或熱壓貼合處理將濾袋與掛耳部接合，因此不需使用噴膠膠黏材質，也不須使用淋膜塗布膠黏材質即可將濾袋與掛耳部接合。並且，掛耳部是由塑膠片形成，也不需在表面塗布濕強劑。本發明之一些實施例的咖啡濾掛結構，在使用時不會有黏著劑與濕強劑釋出於咖啡中，且在使用後可以方便地進行回收。另外，本發明之一些實施例所提出的咖啡濾掛結構的掛耳部跨架在杯緣，因此袋狀底部不會低於杯緣，在使用時袋狀底部不會接觸到液面。To sum up, in the coffee filter hanging structure proposed in some embodiments of the present invention, the filter bag and the hanging ear part are made of the same material, and the filter bag and the hanging ear part can be joined by ultrasonic welding or hot pressing. Therefore, There is no need to use spray adhesive material or lamination coating adhesive material to join the filter bag and the hanging ear part. Moreover, the hanging ears are formed from plastic sheets, and there is no need to apply wet strength agent on the surface. The coffee filter hanging structure of some embodiments of the present invention does not release adhesives and wet strength agents into the coffee during use, and can be easily recycled after use. In addition, the hanging ear portion of the coffee filter hanging structure proposed in some embodiments of the present invention straddles the rim of the cup, so the bottom of the bag will not be lower than the rim of the cup, and the bottom of the bag will not come into contact with the liquid surface during use.
