技术领域Technical field
本发明涉及油墨包装技术领域，尤其涉及一种用于紫外线UV固化型油墨的硬纸筒包装容器。The invention relates to the technical field of ink packaging, in particular to a cardboard packaging container for ultraviolet UV curing ink.
背景技术Background technique
油墨是一种由颜料微粒、填料、附加料等均匀地分散在连接料中,具有一定粘性的流体物质。The ink is a fluid substance which is uniformly dispersed in a binder by pigment particles, fillers, additives, and the like, and has a certain viscosity.
油墨按主要干燥方式的不同，可分为挥发干燥型油墨、渗透干燥型油墨、紫外线UV固化型油墨、双液反应型油墨和紫外线固化型油墨等。Ink according to the main drying method, can be divided into volatile drying ink, osmosis drying ink, UV UV curing ink, two-liquid reactive ink and UV curing ink.
因为考虑到油墨储藏需要的防氧化、防挥发、防紫外线等需求，传统的印刷油墨大多使用金属桶或塑料桶硬质密封包装，导致在印刷操作时，需要人工将油墨从金属桶或塑料桶转移至墨斗池内，并且由于油墨与金属桶或塑料桶直接接触，无法将金属桶或塑料桶内的油墨完全清理干净，残留的油墨在金属桶或塑料桶内固化，这些带有固化后的乳胶状油墨的废弃物是不可燃的，并且具有毒性。所以，这些废弃物不能通过一般性焚烧达到无害化处理。而使用溶剂分解，则会由于溶剂的挥发性，造成大气环境的污染。因此，基于目前的硬质油墨包装，还没有有效环保回收的途径。Because of the anti-oxidation, anti-volatilization, anti-ultraviolet and other requirements required for ink storage, traditional printing inks are mostly sealed in metal drums or plastic drums, resulting in manual ink removal from metal drums or plastic drums during printing operations. Transfer to the ink fountain pool, and because the ink is in direct contact with the metal drum or plastic bucket, the ink in the metal drum or plastic bucket cannot be completely cleaned, and the residual ink is solidified in a metal drum or a plastic bucket, which has the cured latex. The waste of the ink is non-flammable and toxic. Therefore, these wastes cannot be harmlessly treated by general incineration. When solvolysis is used, the atmosphere is polluted due to the volatility of the solvent. Therefore, based on the current rigid ink packaging, there is no effective way to recycle the environment.
而对于纸质材质用于紫外线固化型油墨的容器，在废纸回收中也一直是一个非常难处理的问题，因为光固化后油墨渗透到纸张的纤维中，导致紫外 线固化型油墨无法从纸张纤维中脱离出来，因此成为废纸回收的障碍。For paper containers made of UV-curable inks, it has always been a very difficult problem in waste paper recycling, because the ink penetrates into the fibers of the paper after photocuring, resulting in the UV-curable inks not being able to pass from the paper fibers. Disengaged from the middle, it has become an obstacle to the recycling of waste paper.
发明内容Summary of the invention
本发明的目的是提供一种用于紫外线UV固化型油墨的硬纸筒包装容器，能够解决现有技术中油墨转移需要人工操作，且UV油墨残留造成无法环保回收的问题，通过采用纸质的硬纸筒包装容器，配以内密封活塞压盘，实现油墨的转移，通过导向结构尽可能减少油墨残留，并通过水溶性涂层实现油墨挤出使用后的包装物回收，通过水溶解的方式使残留在包装容器内的油墨与包装容器彻底分离，从而实现对纸质包装容器的材料回收，因而实现环保回收处理。The object of the present invention is to provide a cardboard packaging container for an ultraviolet UV-curable ink, which can solve the problem that the prior art ink transfer requires manual operation, and the UV ink residue causes environmentally-friendly recycling, by adopting paper quality.

具体实施方式detailed description
下面通过附图和实施例，对本发明的技术方案做进一步的详细描述。The technical solution of the present invention will be further described in detail below through the accompanying drawings and embodiments.
本发明实施例提供了一种用于紫外线(ultraviolet，UV)固化型油墨的硬纸筒包装容器，用于容置UV固化型油墨。Embodiments of the present invention provide a cardboard packaging container for an ultraviolet (UV) curing ink for accommodating a UV curable ink.
图1为本发明实施例提供的一种用于UV固化型油墨的硬纸筒包装容器的剖面结构示意图。如图1所示，本发明实施例提供的硬纸筒包装容器包括：纸筒本体1、内密封活塞压盘2和水溶性涂层3和抗紫外线遮光层(图中未示出)。1 is a schematic cross-sectional structural view of a cardboard packaging container for a UV curable ink according to an embodiment of the present invention. As shown in FIG. 1, the cardboard package container provided by the embodiment of the present invention comprises: a paper tube body 1, an inner sealing piston pressure plate 2, a water-soluble coating layer 3, and an ultraviolet-resistant light shielding layer (not shown).
纸筒本体1呈桶装结构，一端具有前封口11和出料口12。The paper tube body 1 has a barrel structure, and has a front seal 11 and a discharge port 12 at one end.
前封口11由位于出料口12两侧，具体由两个对称的导向结构111构成，导向结构111的导向壁112在出料口12的管壁与纸筒本体1的内壁之间呈钝角连接。从而纸筒本体1的这端通过导向结构111和出料口12形成一个漏斗形状，其目的在于有利于油墨能够随导向结构尽量完全的排出包装容器。The front sealing 11 is formed on both sides of the discharge opening 12, specifically by two symmetrical guiding structures 111. The guiding wall 112 of the guiding structure 111 is connected at an obtuse angle between the wall of the discharging opening 12 and the inner wall of the paper tube body 1. . Thus, the end of the cylinder body 1 is formed into a funnel shape by the guiding structure 111 and the discharge opening 12, the purpose of which is to facilitate the ink to be discharged out of the packaging container as completely as possible with the guiding structure.
纸筒本体1可以具体由多层纸张卷贴形成的，前封口11与纸筒本体1由水溶性聚乙烯醇(PVA)贴合固定为一体。The paper tube body 1 can be specifically formed by a multi-layer paper roll, and the front seal 11 and the paper tube body 1 are bonded and fixed by water-soluble polyvinyl alcohol (PVA).
进一步的，在油墨储存状态下，纸筒本体1需要保持密封结构，因此出料口12中具有第一密封膜121，用以防止纸筒本体1内存储的油墨外溢。第一密封膜121为与前封口11一起由纸浆压铸一体成型的，因而密封性能可以得到有效保障。优选的,第一密封膜121上也具有抗紫外线遮光层。Further, in the ink storage state, the paper tube body 1 needs to maintain a sealing structure, so that the discharge port 12 has a first sealing film 121 for preventing the ink stored in the paper tube body 1 from overflowing. The first sealing film 121 is integrally molded by pulp die-casting together with the front seal 11, so that the sealing performance can be effectively secured. Preferably, the first sealing film 121 also has an ultraviolet shielding layer.
为了使用时能够方便的刺破第一密封膜121，可以在第一密封膜121的中心打十字压痕，以方便使用。In order to facilitate the puncture of the first sealing film 121 during use, a cross indentation may be applied at the center of the first sealing film 121 for convenient use.
内密封活塞压盘2，设置于纸筒本体1内，内密封活塞压盘2包括密封盘 21和凸部22。The inner seal piston platen 2 is disposed in the paper tube body 1, and the inner seal piston platen 2 includes a seal disk 21 and a convex portion 22.
密封盘21的外径与纸筒本体1的内径相匹配，通过密封盘21的侧壁与纸筒本体1的内壁密封相接，使得纸筒本体1内部形成密闭结构；密封盘21在外力作用下可以沿纸筒本体1的内壁滑动。这里所说的外力，可以包括但不限于：接在出料口12的泵产生的真空吸力，或者由密封盘21底部传入的推力。The outer diameter of the sealing disk 21 is matched with the inner diameter of the paper tube body 1, and the side wall of the sealing disk 21 is sealingly connected with the inner wall of the paper tube body 1, so that the inside of the paper tube body 1 forms a closed structure; the sealing disk 21 acts externally. The lower portion can slide along the inner wall of the paper tube body 1. The external force referred to herein may include, but is not limited to, a vacuum suction generated by a pump connected to the discharge port 12, or a thrust force introduced from the bottom of the sealing disk 21.
凸部22与密封盘21一体连接。凸部22的顶端呈锥体，底端呈圆柱体，锥体的底面与圆柱体的表面尺寸相吻合，从而能够一体连接。凸部22的最大直径与出料口12的内径相匹配，使得在用于挤压油墨时，凸部22能够探入出料口12，实现油墨的全部压出。尽量减少油墨残留在出料口的残留。The convex portion 22 is integrally connected to the sealing disk 21. The top end of the convex portion 22 is a cone, and the bottom end is a cylindrical body, and the bottom surface of the cone is matched with the surface size of the cylindrical body so as to be integrally connected. The maximum diameter of the projection 22 matches the inner diameter of the discharge opening 12 so that when used to squeeze the ink, the projection 22 can be swung into the discharge opening 12 to achieve full extrusion of the ink. Minimize the residue of ink remaining in the discharge port.
在一些具体的应用中纸筒本体1还具有第二密封膜13，设置于纸筒本体1的底端，使得内密封活塞压盘2被密封在纸筒本体1内部。In some specific applications, the paper tube body 1 also has a second sealing film 13 disposed at the bottom end of the paper tube body 1 such that the inner sealing piston platen 2 is sealed inside the paper tube body 1.
水溶性涂层3，至少涂布于纸筒本体1的内壁和导向壁112上，以及第一密封膜12和内密封活塞压盘2的至少一侧。水溶性涂层3的构成至少包括聚乙烯醇(PVA)。PVA具有溶解于水的特性。The water-soluble coating 3 is applied to at least the inner wall of the paper tube body 1 and the guide wall 112, and at least one side of the first sealing film 12 and the inner sealing piston platen 2. The composition of the water-soluble coating 3 includes at least polyvinyl alcohol (PVA). PVA has the property of being dissolved in water.
在一些具体的实现方式中，水溶性涂层3中还可以包括有塑化剂或者活性剂中的一种或全部。通过加入塑化剂，有利于提高包装容器的柔韧性。In some specific implementations, the water soluble coating 3 may also include one or all of a plasticizer or an active agent. By adding a plasticizer, it is advantageous to increase the flexibility of the packaging container.
抗紫外线遮光层，设置于纸筒本体1的外侧或设置于纸筒本体1上，例如具体可以是在多层卷贴形成纸筒本体1的纸张之间，或者是设置于纸筒本体1之外的单独包装容器上。抗紫外线遮光层用于阻隔紫外线进入纸筒本体1内部造成UV固化型油墨干燥固化。The anti-ultraviolet light shielding layer is disposed on the outer side of the paper tube body 1 or on the paper tube body 1 , and may be, for example, between the paper sheets of the multi-layer roll forming the paper tube body 1 or the paper body 1 . On a separate packaging container. The UV-resistant light-shielding layer is used to block ultraviolet rays from entering the inside of the paper tube body 1 to cause drying and curing of the UV-curable ink.
具体的，抗紫外线遮光层由聚乙烯(PE)、双向拉伸聚丙烯薄膜(BOPP)、聚对苯二甲酸乙二酯(PET)和流延聚丙烯薄膜(CPP)中的任一种或几种材料制成。抗紫外线遮光层的颜色优选为黑色或银色。Specifically, the ultraviolet shielding layer is made of any one of polyethylene (PE), biaxially oriented polypropylene film (BOPP), polyethylene terephthalate (PET), and cast polypropylene film (CPP) or Made of several materials. The color of the ultraviolet resistant light shielding layer is preferably black or silver.
通过本发明用于UV固化型油墨的硬纸筒包装容器的结构设计，在使用时只需将出料口12套接在用于抽取油墨的油墨泵泵口上，由泵口刺破第一密封 膜12，即可通过油墨泵抽取其中容置的UV固化型油墨。By adopting the structural design of the cardboard packaging container for the UV-curable ink of the present invention, it is only required to sleeve the discharge port 12 on the pump port of the ink pump for extracting ink, and the first seal is pierced by the pump port. The film 12, that is, the UV curable ink contained therein can be extracted by an ink pump.
随着油墨的抽出，内密封活塞压盘2至前封口11一侧的压力减小，按图1所示方向，内密封活塞压盘2右侧的密闭空间相对于内密封活塞压盘2左侧形成负压，使得内密封活塞压盘2在负压作用下向右侧，即朝向出料口12方向运动，以减小右侧的密闭空间的容积来平衡内密封活塞压盘2左右两侧的压力。As the ink is drawn out, the pressure on the side of the inner seal piston platen 2 to the front seal 11 is reduced, and in the direction shown in Fig. 1, the closed space on the right side of the inner seal piston platen 2 is opposite to the inner seal piston platen 2 The side forms a negative pressure, so that the inner seal piston platen 2 moves to the right side under the action of the negative pressure, that is, toward the discharge port 12, to reduce the volume of the closed space on the right side to balance the inner seal piston platen 2 Side pressure.
当内密封活塞压盘2移动至接近到前封口11时，纸筒本体1内的剩余油墨会随着内密封活塞压盘2的移动而沿着导向壁112流出至出料口12，这样避免了直角式的筒体结构在直角连接处的油墨残存问题。随着内密封活塞压盘2的进一步移动，凸部22探入出料口12，将最后残留在出料口12处的油墨全部挤出。When the inner seal piston platen 2 is moved to approach the front seal 11, the remaining ink in the cylinder body 1 flows out along the guide wall 112 to the discharge port 12 as the inner seal piston platen 2 moves, thus avoiding The right-angled cylinder structure has ink retention problems at right angle joints. As the inner seal piston platen 2 is further moved, the projection 22 penetrates into the discharge port 12, and the ink remaining at the discharge port 12 is completely extruded.
涂布均匀于纸筒本体1的内壁和导向壁112上、第一密封膜12和内密封活塞压盘2的至少一侧的水溶性涂层3，可以有效阻挡纸筒本体1外部的氧气分子穿透水溶性涂层3与容置于水溶性纸筒本体1之内UV固化型油墨相接触而造成油墨的氧化干燥。The water-soluble coating layer 3 uniformly coated on the inner wall of the paper tube body 1 and the guide wall 112, the first sealing film 12 and the inner sealing piston platen 2 can effectively block the oxygen molecules outside the paper tube body 1. The water-soluble coating 3 penetrates into contact with the UV-curable ink contained in the water-soluble paper tube body 1 to cause oxidative drying of the ink.
本发明提供的硬纸筒包装容器，在灌装油墨时，前封口11及第一密封膜121与纸筒本体1已粘合为一体，成密封状态。相反一侧的后端,内密封活塞压盘2与纸筒本体1分离。In the cardboard package container provided by the present invention, when the ink is filled, the front seal 11 and the first sealing film 121 and the paper tube body 1 are bonded together to be in a sealed state. On the opposite side of the rear end, the inner seal piston platen 2 is separated from the cylinder body 1.
当定量油墨注入纸筒本体1后，后端的内密封活塞压盘2可被装配机械推送入纸筒本体1内，内侧与油墨上表面接触。After the metering ink is injected into the paper tube body 1, the inner sealing piston platen 2 at the rear end can be mechanically pushed into the paper tube body 1 with the inner side in contact with the upper surface of the ink.
在此情况下，如有更高密封要求，还可在纸筒本体1的后端粘贴第二密封膜13，以保证密封性能，避免油墨外溢。In this case, if there is a higher sealing requirement, the second sealing film 13 may be attached to the rear end of the paper tube body 1 to ensure the sealing performance and avoid ink overflow.
进一步的，基于UV固化型油墨存储的时间和存储条件的不同，还可以如图1所示在纸筒本体1外层加设防水层4，从而避免空气中的水气对硬纸筒包装容器的性能产生影响。Further, based on the time and storage conditions of the UV-curable ink storage, a waterproof layer 4 may be added to the outer layer of the paper tube body 1 as shown in FIG. 1 to avoid moisture in the air to the cardboard container. The performance has an impact.
具体的，如图1所示，防水层4包裹于纸筒本体1的外表面，呈密封结 构，用于阻隔水分子透过防水层4进入防水层4内部。其中，防水层4的密封可以优选为在惰性气体环境下采用加热密封来实现。Specifically, as shown in FIG. 1, the waterproof layer 4 is wrapped around the outer surface of the paper tube body 1 in a sealed structure for blocking water molecules from entering the waterproof layer 4 through the waterproof layer 4. Among them, the sealing of the waterproof layer 4 can preferably be achieved by using a heat seal under an inert gas atmosphere.
因为在空气湿度较大或者存储时间较长的条件下，水溶性涂层3中的PVA容易与空气中的水分子相结合，产生溶胀现象。因此如果水分子吸入纸筒本体1后，会与水溶性涂层3相接触，造成PVA体积膨胀，从而引起水溶性涂层3对氧气分子的阻隔性能下降，容易造成油墨氧化干燥。因此通过增加防水层4能够进一步提升对UV固化型油墨的存储性能。Since the PVA in the water-soluble coating 3 is easily combined with water molecules in the air under conditions of a large air humidity or a long storage time, a swelling phenomenon occurs. Therefore, if the water molecules are sucked into the main body 1 of the paper, they will come into contact with the water-soluble coating layer 3, causing the volume of the PVA to expand, thereby causing the water-soluble coating layer 3 to have a lower barrier property against oxygen molecules, which tends to cause oxidative drying of the ink. Therefore, the storage performance of the UV curable ink can be further improved by adding the waterproof layer 4.
防水层4可以具体由防水膜材料制成，可以具体为：聚乙烯(PE)、双向拉伸聚丙烯薄膜(BOPP)、聚对苯二甲酸乙二酯(PET)或者流延聚丙烯薄膜(CPP)等。防水层4可以同时作为抗紫外线遮光层，起到对UV进行防护的作用。The waterproof layer 4 may be specifically made of a waterproof membrane material, and may specifically be: polyethylene (PE), biaxially oriented polypropylene film (BOPP), polyethylene terephthalate (PET) or cast polypropylene film ( CPP) and so on. The waterproof layer 4 can simultaneously serve as an ultraviolet-resistant light-shielding layer to protect the UV.
纸筒本体1的外表面与防水层4的内表面可以不相接，在使用中只需去除防水层4即可取出装有UV固化型油墨的纸筒本体1。被去除掉的防水层4能够单独进行环保回收。在图1中仅针对防水层4中装置有一个油墨包装袋的情况进行了示意，在实际应用中，可以按照常规使用量，将多个硬纸筒包装容器置于一个防水层4中进行存储，即方便用户使用，又经济环保。The outer surface of the paper tube body 1 may not be in contact with the inner surface of the waterproof layer 4. In use, the paper tube body 1 containing the UV-curable ink may be taken out by simply removing the waterproof layer 4. The removed waterproof layer 4 can be environmentally recovered separately. In Fig. 1, only the case where an ink package is installed in the waterproof layer 4 is illustrated. In practical applications, a plurality of cardboard containers can be placed in a waterproof layer 4 for storage according to a conventional usage. , that is convenient for users to use, and economic and environmental protection.
