Abstract

The invention relates to an environment-friendly paper container which comprises a container body and an inner protective layer combined with the container body. The container body is made of paper and comprises an inner surface defining an accommodating space. The inner protective layer is combined on the inner surface of the container main body and comprises a biodegradable component coated along the inner surface. The biodegradable component comprises a main raw material selected from polybutanediol-1,4-succinate. Therefore, by adopting the water resistance, the heat deformation temperature up to about 90 DEG C and the biodegradability of PBS (PolyButanediol Succinate), the direct contact between the container main body and the liquid in a cup is obstructed by using the protective layer to prevent the container body from being soaked. When the environment-friendly paper container is used for holding hot beverages, the container body can be effectively prevented from damage through the protective layer, and the environment-friendly paper container is environment-friendly and practical as the protective layer can be decomposed in the natural environment.

Description

环保纸容器 Environmentally friendly paper containers

技术领域 FIELD

[0001] 本发明涉及一种纸容器,特别是涉及一种表面披覆有一层耐水耐热的防护层的环保纸容器。 [0001] The present invention relates to a paper container, in particular, relates to a surface protective layer is coated with a layer of green paper container of water-resistant.

背景技术 Background technique

[0002]目前市面上常见的免洗杯主要有塑胶制与纸制二种,随着环保意识日益高涨,不容易在自然环境中分解的塑胶杯逐渐遭到淘汰,并以生物降解性材质或纸质所制成的免洗杯为主。 [0002] Common market of disposable cups made of plastic and paper are mainly two kinds, with the growing awareness of environmental protection, do not break down the plastic cups in the natural environment is gradually being phased out and a biodegradable material or disposable cup made of paper-based. 其中,由于纸制品能在自然环境中分解,又容易回收再制,使免洗纸杯广泛地被一般餐饮店、茶店或咖啡店作为外带杯使用。 Wherein, because paper products can be decomposed in the natural environment, and easy recycling system, so Disposable cups are generally widely restaurants, coffee shops, or as a take-away cup tea shops use.

[0003] 请参阅图I所示,是一说明现有的一个纸杯的结构剖视示意图,现有的一纸杯1, 具有一杯体11,以及一层披覆在该杯体11 一内表面111的防护层12。 [0003] Referring to FIG I, the conventional structure is an explanatory cross-sectional view of a paper cup, a conventional paper cup 1, having a cup member 11, and a layer 11 coated on an inner surface of the cup 111 the protective layer 12. 该防护层12是借由将熔融的低密度聚乙烯(low densitypolyethylene,简称为LDPE)涂布至该杯体11的内表面111而形成,由于LDPE的软化点为80°C〜101°C,且其熔点为108°C〜110°C,又有耐酸、碱腐蚀的特性,因此适合作为该杯体11与液体间的防护层11,可有效阻隔纸质的杯体11受液体影响。 The protective layer 12 is formed by means of a molten low-density polyethylene (low densitypolyethylene, abbreviated as LDPE) is applied to the inner surface 11 of the cup body 111, since the softening point of the LDPE is 80 ° C~101 ° C, and a melting point of 108 ° C~110 ° C, there are acid and alkali corrosion properties, it is suitable as a liquid cup affect the cup 11 between the guard and the liquid layer 11, 11 can effectively block the paper receiving. 借此,当该纸杯I内盛装液体时,可借由该防护层12防止杯内液体浸湿整个杯体11,导致该杯体11松软变形,由于该防护层12熔点较高,使该纸杯I也能用于盛装热饮。 Whereby, when the cup containing liquid I, can be wetted the entire cup body 11 by means of the protective layer 12 prevents the cup of the liquid, resulting in deformation of the soft cup 11, due to the higher melting point of the protective layer 12, so that the cups I can also be used to hold hot drinks.

[0004] 虽然该纸杯I能借由在该杯体11的内表面111披覆该防护层12达到盛装液体时不易被浸湿变形或破损的效果,但由于该防护层12是由LDPE所制成,LDPE虽然有较佳的防水耐热效果,但属于不易在自然环境中分解的塑胶材质,因此,以LDPE为该防护层12所制成的纸杯I仍具有使用上较不环保的缺失。 [0004] Although the cup 111 I can be coated by means of the effect of anti-wetting deformed or damaged when the content liquid 12 reaches the protective layer of the inner surface of the cup body 11, but since the protective layer 12 is prepared from LDPE so, although the preferred LDPE heat waterproofing effect, but are made of plastic material is difficult to decompose in the natural environment, so as to cups made of LDPE I for protective layer 12 still has less environmental deletion use.

[0005] 有鉴于此,现有的另一种纸杯同样具有一杯体及一层披覆在该杯体内表面的防护层,且该防护层改由聚乳酸(polylacticacid,简称为PLA,亦称为聚丙交酯)制成,虽然聚乳酸是能在自然环境分解的生物降解性材料,相对不易造成环保上的问题,但由于聚乳酸的软化点(glass transition,亦称为玻璃转移温度)是约为58°C〜60°C,耐热性不佳,当以该纸杯盛装热饮时,会造成该防护层脱胶,导致纸质的杯体直接接触到液体而浸湿变形,甚至破损而无法使用,使该聚乳酸材质的防护层相对具有防护效果较差的缺失。 [0005] In view of this, another conventional cups having a cup body and a layer of the same coated on the inner surface of the cup of the protective layer, and the protective layer is replaced by polylactic acid (polylacticacid, abbreviated as PLA, also known as polylactide) is made, although the polylactic acid is a biodegradable material able to decompose the natural environment, relatively easy to cause environmental problems, but the softening point of the polylactic acid (glass transition, also referred to as glass transition temperature) of about of 58 ° C~60 ° C, the heat resistance is poor, when the cup containing hot to, the guard will cause debonding layer, resulting in a paper cup is in direct contact with the liquid to wet deformed, damaged or even unusable the material of the protective layer of polylactic acid having a relatively poor protective effect deletions.

[0006] 此外,现有制造纸杯的方式多是将防护层涂在一纸质板体上,再将已涂布有该防护层的纸质板体进一步加工成型为该纸杯,当以PLA为该防护层材质,并将PLA涂覆在该纸质板体上时,由于PLA在常温下质地较硬,且附着力不佳,极容易在加工成型的过程中剥落,导致该纸杯的制造优良率极差,反而会增加制造成本。 [0006] Further, the conventional way of manufacturing a plurality of cups is a protective layer coated on a paper plate, and then the paper is coated with a protective layer of the board is further processed for forming cups, when PLA-based the material of the protective layer, and the PLA coated on the paper plate, since the PLA hard texture at room temperature, and poor adhesion, very easy to peel off during the molding process, resulting in the good manufacturing paper cups poor rate, but it will increase manufacturing costs.

[0007] 为了改善PLA附着力不佳的缺点,现有另一种制造方式是先在该杯体表面涂布一界面活性剂层,再披覆上PLA材质的该防护层,以通过该界面活性剂层增加该防护层与该杯体结合的附着力,虽然可通过这种方式减少该防护层自该杯体剥落的情形发生,但由于界面活性剂多为有毒物质,当以该纸杯盛装液体时,界面活性剂中的毒素可能穿过该防护层渗出并释放到杯内液体中,而具有容易危害人体健康的缺失。 [0007] In order to improve the shortcomings of poor adhesion PLA, another manufacturing method is prior to the first protective layer is applied to the surface of the cup body in a surfactant layer, and then coated on the PLA material, through the interface increase the adhesion of the active agent layer the protective layer is bonded to the cup body, although the protective layer can be reduced in this way from the case of the cup body peeling occurred, but the surfactant, mostly toxic substances to the cup when dressed liquid, surfactant toxins may bleed through the protective layer and is released into the liquid in the cup, and having a deletion readily harmful to human health. [0008] 由此可见,上述现有的纸容器在结构与使用上,显然仍存在有不便与缺陷,而亟待加以进一步改进。 [0008] Thus, the conventional paper containers in structure and use, there is clearly still problems and disadvantages, and the urgent need to be further improved. 为了解决上述存在的问题,相关厂商莫不费尽心思来谋求解决之道,但长久以来一直未见适用的设计被发展完成,而一般产品又没有适切结构能够解决上述问题,此显然是相关业者急欲解决的问题。 In order to solve the above problems, the firms did not dare to think hard and to seek a solution, but has long been seen to be applicable to the design of the development is complete, and general product and no relevance structure can solve the above problems, this is obviously related businesses anxious to solve the problem. 因此如何能创设一种新型结构的环保纸容器,实属当前重要研发课题之一,亦成为当前业界极需改进的目标。 So how can we create a new type of environmentally friendly paper containers structure, it is currently one of the important research and development issues, has become the current industry in dire need of improvement goals.

[0026] 请参阅图2所示,是一说明本发明环保纸容器一第一较佳实施例的剖视示意图。 [0026] Please refer to FIG. 2, it is a schematic cross-sectional view of the paper container of the present invention, a first environmentally preferred embodiment will be described. 本发明的一个第一较佳实施例的环保纸容器2,包含一个容器本体21,以及一层结合在该容器本体21上的内防护层22。 Environmental paper container according to one preferred embodiment of the present invention, the first 2, comprises a container body 21, and a layer bonded to the container body 21 of the inner protective layer 22. 在此是以纸杯型式的纸容器2进行说明,但该纸容器2的型式并不限于纸杯,该纸容器2可以是各种能用于盛装液体101或食物的杯、盒、碗、碟等容器。 In this type of paper container 2 is cup will be described, but the type of paper container 2 is not limited to cups, which may be a paper container 2 for holding a liquid 101 can be a variety of food or cups, boxes, bowls, plates, etc. container.

[0027] 该容器本体21,是由纸质所制成,包括一个界定出一个容装空间210,并形成有一个使该容装空间210与外界相连通的开口212的内表面211,及一个与该内表面211相间隔的外表面213。 [0027] The container body 21, is made of paper, comprising a means defining a receiving space 210, and is formed with an accommodating space 210 so that the inner surface 212 of the opening 211 in communication with the outside, and a the outer surface and the inner surface 211 spaced 213.

[0028] 该内防护层22,是披覆并结合在该容器本体21的内表面211,且是由一个熔融并沿该内表面211涂布的生物降解性组份而形成,该生物降解性组份包括一个主原料,且该主原料是选自于聚丁二酸-I、4_ 丁二醇酯(polybutylene-1、4_succinate,简称为PBS)。 [0028] The inner protective layer 22 is coated and incorporated within the surface 21 of the container body 211, and is formed from a melt and coated with 211 parts along the inner surface of the biodegradable groups of the biodegradable a component comprising a main raw material, and the main raw material is selected from the group polybutylene succinate, -I, 4_ polybutylene terephthalate (polybutylene-1,4_succinate, abbreviated as PBS).

[0029] 将该生物降解性组份涂布至该容器本体21的内表面211形成该内防护层22的方式,与现有的将PE涂布至纸杯杯体的技术相同,在此不再赘述。 [0029] The parts of the biodegradable group is applied to the inner surface 211 of the container body 21 is formed so that the inner protective layer 22, the same technique with conventional paper cups of the cup body applied to the PE, which is not repeat.
