Description
本發明有關一種具有強化表面之紙餐盒及其製法，尤指一種以兩階段方式所成型，並以水氣使第一階段所成型之紙餐盒之預定位置軟化，再熱壓一體成型具有唇邊及凹凸強化表面之紙餐盒。 The invention relates to a paper lunch box with a strengthened surface and a preparation method thereof, in particular to a two-stage method, which softens a predetermined position of a paper lunch box formed by the first stage with water vapor, and then is integrally formed by hot pressing. Paper lunch box with lip and bump-reinforced surface.
按，傳統的免洗餐具(一次性餐具)大都是塑膠製品、保麗龍(聚苯乙烯)或紙類所製成，其中又以保麗龍(聚苯乙烯)所製成之免洗餐具，遇熱會排放出毒素，對人體健康有害，且該餐具無法自然分解，會造成環境的污染，因已經被很多國家禁止使用。 According to the traditional disposable tableware (disposable tableware), most of them are made of plastic products, styrofoam (polystyrene) or paper, and the disposable tableware made of styrofoam (polystyrene). The heat will emit toxins, which are harmful to human health, and the tableware cannot be naturally decomposed, which will cause environmental pollution, which has been banned in many countries.
因此市場對紙製餐盒需求量大增，遂有業者不斷研發出各種不同結構之紙製餐盒。而傳統紙製餐盒之結構及製法，係如圖1A及1B所示，將紙板裁切成一預定形狀的餐盒紙胚60，該餐盒紙胚60具有盒底61、盒邊板62、四端角之摺片63及蓋體64等，上述各部位皆係相互連結為一體，經一成型模具熱壓合，使上述四端角之摺片63相互貼合，成為一立體紙製餐盒60A。 Therefore, the demand for paper lunch boxes has increased greatly in the market, and many manufacturers have continuously developed paper lunch boxes of various structures. The structure and manufacturing method of the conventional paper lunch box are as shown in FIGS. 1A and 1B, and the paperboard is cut into a predetermined shape of a lunch box paper 60 having a box bottom 61 and a box side board 62. The four-end corner flap 63 and the lid body 64 are integrally connected to each other, and are thermocompression-bonded by a molding die to bond the four-end corner flaps 63 to each other to form a three-dimensional paper system. Lunch box 60A.
惟查，傳統紙製餐盒60A結構，其最大的問題點在於其熱壓合成型後的盒體61a或蓋體64a，因為紙板不具延伸性，所以無法像塑膠或保麗龍餐盒，可以一體成型具有凹凸之補強肋體或表面，因此成型後之紙製餐盒60A，其結構強度相對不足，承放食物時易產生變形；再者，其四端角之摺片63重疊後之結合面利用膠體予以黏著貼合，但此種黏合方式成型後之立體紙餐盒60A的結構較不牢固，若往兩相對框邊稍加施力外拉，容易導致端角之摺片63撕開或損壞，如此一來，當餐盒內盛裝菜餚湯汁時，容易從貼合處滲漏，是故，尚有改善空間。 However, the traditional paper box 60A structure, the biggest problem lies in its hot-pressed type of box body 61a or cover body 64a, because the cardboard is not extensible, it can not be like plastic or styrofoam lunch box, can The reinforcing ribs or surfaces having irregularities are integrally formed, so that the formed paper lunch box 60A has a relatively insufficient structural strength, and is easily deformed when the food is placed; further, the combination of the four-corner flaps 63 is overlapped. The surface is adhered by a colloid, but the structure of the three-dimensional paper lunch box 60A formed by the bonding method is relatively weak, and if the two opposite sides of the frame are slightly applied, the flap 63 of the end corner is easily torn. Or damage, as a result, when the soup is contained in the lunch box, it is easy to leak from the fitting. Therefore, there is still room for improvement.
又按，如圖1C所示，有的紙餐盒70係分隔成數個間格，例如紙餐盒的盒體71被橫隔體72a一分為二，以及在被分隔後的二分之一盒體中，再縱隔體72b分隔成二~三小間格，用以區分飯菜及不同的菜餚，由於紙材料的因素，紙餐盒70不能像以往塑膠餐盒那樣一次壓模成型，其紙餐盒70的生產製程是將紙片材料根據分格餐盒形狀的要求進行模切和壓痕，然後對模切和壓痕後的切片進行壓折、粘合而形成所需形狀的分格紙餐盒，即橫隔體72a一般都是由壓成紙餐盒的紙片材料折疊而成，而兩條縱隔體72b則是需要另外事先模切和壓痕後的分格壁切片從切片經通過輸送系統送進模具中壓合形成的。因此，製造分格紙餐盒時，首先將帶有橫隔體72a的紙餐盒主體模切片模壓成型，同時另將縱隔體72b切片模壓成型，最後將成型的縱隔體72b與帶有橫隔體72a的盒體71模壓熔接。當然也有其他製法，例如：橫隔體72a與縱隔體72b都同時在一部成型機先成型，然後再與盒體71模壓熔接。惟查，無論以何種方式熔接該分格用隔體，其仍然有圖1B所示之紙製餐盒60A的缺點。 Further, as shown in FIG. 1C, some paper lunch boxes 70 are divided into a plurality of compartments, for example, the box 71 of the paper lunch box is divided into two by the transverse body 72a, and one half of the separated compartments. In the box body, the further mediastinum 72b is divided into two to three small compartments for distinguishing between meals and different dishes. Due to the paper material factor, the paper lunch box 70 cannot be molded once like a plastic lunch box. The production process of the box 70 is to die-cut and indent the paper sheet material according to the shape of the divided lunch box, and then press-bond and bond the die-cut and indented slices to form a grid-shaped meal of a desired shape. The box, that is, the cross-body 72a is generally folded from the sheet material pressed into the paper lunch box, and the two mediastinums 72b are separated by the die-cutting and indentation. The system is fed into the mold to form a press. Therefore, when manufacturing the compartment paper lunch box, the paper box body with the cross-body 72a is first molded and molded, and the mediastinum 72b is slice-molded, and finally the formed mediastinum 72b is provided with a diaphragm. The casing 71 of the body 72a is press-welded. Of course, there are other methods. For example, the transverse body 72a and the longitudinal partition 72b are simultaneously molded in one molding machine, and then molded and welded to the casing 71. However, it is checked that no matter how the spacer spacer is welded, it still has the disadvantage of the paper lunch box 60A shown in Fig. 1B.
再按，習用之紙餐盒70之盒體71的周緣73為紙板的裁斷面，並無唇緣構造，因此周緣73的地方非常銳利，易割傷使用者；再者，因缺乏強化作用，承載食物時容易彎折，造成傾倒或變形，但因受限於紙板不具延伸性，所以無法像塑膠或保麗龍餐盒，可以一體成型具有唇緣，是以，仍有改善空間。 Further, the peripheral edge 73 of the box 71 of the conventional paper lunch box 70 is a cut surface of the cardboard, and has no lip structure. Therefore, the peripheral edge 73 is very sharp and easily cuts the user; furthermore, due to lack of strengthening, When carrying food, it is easy to bend, causing dumping or deformation. However, due to the fact that the cardboard is not extensible, it cannot be like a plastic or styrophone lunch box. It can be integrally formed with a lip. Therefore, there is still room for improvement.

本發明之主要特徵在於：接續在第一階段(I)之後的第二階段(II)，其步驟係包括：提供一組具有上模具51、下模具52的熱壓成型設備50，由於該熱壓成型設備50為先前技術，其熱壓成型原理及結構容不詳述。 The main feature of the present invention resides in the continuation of the second stage (II) after the first stage (I), the steps comprising: providing a set of hot press forming apparatus 50 having an upper mold 51 and a lower mold 52, due to the heat The press forming apparatus 50 is a prior art, and the hot press forming principle and structure are not described in detail.
如圖3所示，將前述第一階段(I)所成型之紙餐盒30A(可具有分隔體11)送入該下模具52，該下模具52連接一水氣供給裝置40，且其成型凹模表面，於預定位置設有多數之氣孔41，俾對該紙餐盒30A用水氣噴濕，使該紙餐盒30之預定位置呈現軟化；如圖4所示，該紙餐盒30A在進入局部熱壓合之前，其預定位置已經吸附水氣呈現軟化13a、21a的狀態。 As shown in FIG. 3, the paper lunch box 30A (which may have the separator 11) formed in the first stage (I) is fed into the lower mold 52, and the lower mold 52 is connected to a water gas supply device 40, and is formed. The concave mold surface is provided with a plurality of air holes 41 at predetermined positions, and the paper lunch box 30A is sprayed with water to soften the predetermined position of the paper lunch box 30; as shown in FIG. 4, the paper lunch box 30A is Before entering the local thermocompression, the predetermined position has adsorbed the state in which the moisture exhibits softening 13a, 21a.
本實施例中，該水氣供給裝置40更包括：一水氣室42，其一端連接一汽泵43，且該水氣室42另一端連接一輸氣管路44，藉由該汽泵43將水氣輸送至該下模具52之氣孔41，並經由該氣孔41噴向該紙餐盒30A預備軟化之部位。進一步，該汽泵43與該水氣室42之間更包括設有一單向調節閥45。另該下模具52內部設有電熱管522，且該電熱管522連一溫度控制器523。 In this embodiment, the water gas supply device 40 further includes a water vapor chamber 42 connected to a steam pump 43 at one end, and the other end of the water gas chamber 42 is connected to a gas supply line 44, and the water is pumped by the steam pump 43. The gas is supplied to the air holes 41 of the lower mold 52, and is sprayed through the air holes 41 to the portion where the paper lunch box 30A is to be softened. Further, the steam pump 43 and the water chamber 42 further include a one-way regulating valve 45. In addition, an electric heating tube 522 is disposed inside the lower mold 52, and the electric heating tube 522 is connected to a temperature controller 523.
本發明係在該上、下模具51、52的表面分別設有預定深度的凹凸形體511、521，以該上、下模具51、52對該盒體10及蓋體20之局部軟化位置，進行120℃~160℃的熱壓合。本實施例中，該氣孔41係設在該下模具52的成型凹模表面，俾在該上、下模具51、52進行熱壓合之前， 使該紙餐盒30A預定位置先吸附水氣而軟化13a、21a，如此才能使該預壓合的區域具有延展性。再者，如圖3A所示，該下模具52的上週緣設有一凹面524，作為紙餐盒30A摺唇邊之用。 In the present invention, the surface of the upper and lower molds 51, 52 are respectively provided with concavo-convex shapes 511, 521 of a predetermined depth, and the partial softening positions of the upper and lower molds 51, 52 of the casing 10 and the cover 20 are performed. Thermal compression at 120 ° C ~ 160 ° C. In this embodiment, the air hole 41 is disposed on the surface of the molding die of the lower mold 52, before the upper and lower molds 51 and 52 are thermally pressed. The predetermined position of the paper lunch box 30A is first adsorbed by moisture to soften 13a, 21a, so that the pre-compressed region is malleable. Further, as shown in FIG. 3A, the upper periphery of the lower mold 52 is provided with a concave surface 524 for folding the lip of the paper lunch box 30A.
承上，控制該上、下模具51、52的熱壓合時間，使該盒體10及蓋體20的周緣一體成型具有一唇邊12、22，且其表面分別具有複數凹凸結構之強化表面13、21，一體成型如圖5所示之強化紙餐盒30B。本實施例中，該上、下模具51、52的熱壓合時間，僅需數秒鐘即可使紙餐盒30A上吸附蒸氣而局部軟化13a、21a的區域，延展成具有唇邊12、22及強化表面13、21。該唇邊12、22係分別由該盒體10及蓋體20的開口端面向外翻摺成水平狀所構成。此外，盒體10及蓋體20在熱壓合延展時，可同步使其四個端角修飾成圓弧面14，23，不僅可增加強度，且使用時亦較圓潤滑順。 The thermal compression time of the upper and lower molds 51 and 52 is controlled to integrally form the periphery of the casing 10 and the cover 20 with a lip 12 and 22, and the surface thereof has a reinforcing surface of a plurality of concave and convex structures. 13, 21, integrally formed as shown in Figure 5 of the enhanced paper lunch box 30B. In this embodiment, the hot pressing time of the upper and lower molds 51, 52 can be used to make the portion of the paper lunch box 30A which is vaporized to locally soften 13a, 21a, and extend to have the lips 12, 22 in only a few seconds. And strengthening the surface 13, 21. The lips 12 and 22 are respectively formed by folding the opening end faces of the casing 10 and the lid 20 into a horizontal shape. In addition, when the casing 10 and the lid body 20 are thermally pressed and expanded, the four end angles can be simultaneously modified into the circular arc surfaces 14, 23, which not only increases the strength, but also is smooth and smooth when used.
因此，在該紙餐盒30A之預定位置預先噴射水氣使其軟化具有延展性，再對該局部軟化位置進行熱壓合成型，係為本發明的重要技術手段，如果缺少此一步驟，則無法達成強化紙餐盒30B。再者，在具有分隔體11之紙餐盒30A上，無法在餐盒紙胚階段，就使其吸收水氣軟化，因為軟化的盒體10無法熔接分隔體11；而本發明則在分隔體11熔接完成後，再進行第二階段(II)的局部熱壓合延展成型。 Therefore, it is an important technical means of the present invention to inject water gas in advance at a predetermined position of the paper lunch box 30A to soften it and to expand the local softening position. If this step is absent, The enhanced paper lunch box 30B could not be reached. Further, on the paper lunch box 30A having the separator 11, it is impossible to soften the water vapor absorption at the stage of the paper box, since the softened case 10 cannot weld the separator 11, and the present invention is in the separator. After the completion of the welding, the second hot pressing and forming of the second stage (II) is performed.
是以，本發明依據上揭技術手段所製成之強化紙餐盒30B結構，其包括：一紙餐盒30A，該紙餐盒30A具有一盒體10及蓋體20；該強化紙餐盒30B之預定位置預先噴射水氣使其軟化13a、21a，再對該局部軟化位置進行熱壓合；以及該盒體10周緣一體成型具有一唇邊12、22，且該盒體10及蓋體20的表面，分別具有複數凹凸結構之強化表面13、21，據以構成一強化紙餐盒30B。 Therefore, the structure of the enhanced paper lunch box 30B made by the present invention according to the above technical means comprises: a paper lunch box 30A having a box body 10 and a cover body 20; the reinforcing paper lunch box The predetermined position of 30B is previously sprayed with moisture to soften 13a, 21a, and then the partial softening position is thermocompression; and the periphery of the casing 10 is integrally formed with a lip 12, 22, and the casing 10 and the cover The surface of 20 has reinforcing surfaces 13, 21 each having a plurality of concave-convex structures, thereby constituting a reinforced paper lunch box 30B.
藉助上揭技術特徵，本發明以兩階段方式，將已成型之紙餐盒30A，接續水氣使其局部軟化具有延展性，使得紙餐盒二階段熱壓合成型時，即形成具有唇邊12、22及凹凸之強化表面13、21，具有足夠的結構強度及密合度，有效解決先前技術之問題點。再者，本發明之表面強化方法，可應用於目前的紙餐盒成型機之後面繼續加工，原紙餐盒成型機無須廢棄，具有製作便捷且經濟效益高之功效增進。 By means of the above-mentioned technical features, the present invention in a two-stage manner, the formed paper lunch box 30A is connected to the water gas to soften it locally and has ductility, so that when the paper lunch box is hot-pressed in two stages, the lip is formed.
