M392811 五、新型說明： 【新型所屬之技術領域】 本創作係有關一種緩衝包裝結構，旨在提供一種可兼顧 硬度及緩衝力之緩衝包裝結構。 【先前技術】 就目前資訊電子產品的產銷型態而言，大多都是在不同 .地點分別進行產品之生產、組裝及配銷等作業，使得資訊電 •子產品的零件或半成品必須在加工廠或廠商間運送。由於資 訊電子類產品的出貨量往往非常大，而為了節省其零件或半 成品的物流運送成本，業界都是將多數個零件或半成品共同 包裝再一起進行運送。但是，多個零件或半成品共同包裝， 使產品在運送的過程中會容易相互碰撞而損壞，而且資訊電 子類產品不僅精密度高且單價昂貴，例如液晶螢幕之液晶_ 不模組’並無法承受外界的撞擊或較大的作用力。 因此’在包裝此類資訊電子類產品時就必須將防護措施 *納入必要考量，例如以保麗龍（E. P.S)、E.P.E發泡聚乙烯 ’ ^^yethyiene Foam)或瓦楞紙板等所製成之緩衝發泡材失 覆於產品外’再將產品連同緩衝材一併置放於包裝箱，以利 用緩衝材吸收運送過程中來自外界的衝擊力，這樣才能確保 出廠後產品之品質及完整性。 如第一圖所示，即為一種利用低密度發泡材料所製成呈 平板狀的緩衝發泡材1，低密度發泡材具有良好的缓衝效果， 在使用上，人員可依待包裝物的體積大小所需，適當裁切緩 衝發泡材1 ;低密度發泡材雖然具有良好的緩衝效果’然而 3 M392811 因密度低，容易被刺破，且荷重承載後，厚度會變薄，造成 包裝品在運輸過程中容易產生滑動及磨擦受損。 當包裝品2屬於耐震程度較低時，例如精密度高之資訊 電子類產品，非常怕碰撞，因此包裝材料必須具有足夠的硬 度，才能提供良好的防碰撞保護，此時如第二圖所示，人員 必須先將多個如第一圖所示之緩衝發泡材1重疊黏接直至足 夠的硬度，才能進行後續的包裝作業。但是多數層緩衝發泡 材1卻會造成包裝後的整體體積變得很龐大，很佔空間，特 別是對於外銷業者而言，一個貨櫃的儲物空間固定，緩衝發 泡材1的體積增加，相對會造成貨櫃的儲物量降低，貨運成 本因而提高。 【新型内容】 有鑑於此，本創作「緩衝包裝結構」之主要目的，係提 供一種兼顧硬度及緩衝力之緩衝包裝結構。 為達上述目的，本創作中緩衝包裝結構係至少設有：高 密度發泡緩衝層、低密度發泡緩衝層以及中密度發泡緩衝 層，該高密度發泡緩衝層係位於該緩衝包裝結構之外側，可 藉由該高密度發泡緩衝層提高整體硬度，可減少因撞擊所受 之傷害以及被穿透之可能性，並利用密度低於高密度發泡緩 衝層之低密度發泡緩衝層及/或中密度發泡緩衝層提供適當 之緩衝力，以提供包裝品最佳之保護效果。 【實施方式】 本創作之特點，可參閱本案圖式及實施例之詳細說明而 M392811 獲得清楚地瞭解。 本創作「緩衝包裝結構」如第三圖之第一實施例所示， 該緩衝包裝結構3，其至少包含有： 一高密度發泡緩衝層31，係為高密度聚乙烯發泡材製 成，其硬度較高而可提供較佳支撐力； 一低密度發泡緩衝層32,係為低密度聚乙烯發泡材製 '成，具有彈性而可提供較佳緩衝力，係設於該高密度發泡緩 - 衝層31 —側；以及 ® —中密度發泡緩衝層33,係為中密度聚乙烯發泡材製 成，係設於該低密度發泡緩衝層32相對於該高密度發泡緩衝 脣31之另側。 其中，整體緩衝包裝結構3由上而下依序為高密度發泡 緩衝層31、低密度發泡緩衝層32以及中密度發泡緩衝層33, 各緩衝層31、32、33間進一步設有黏著層34，用以將各緩 衝層31、32、33間利用熱壓固定成型。 再者，如第四圖所示為本創作之第二實施例，該緩衝包 • 裝結構3同樣包含有：密度發泡緩衝層31、低密度發泡緩衝 • 層32以及中密度發泡緩衝層33，其中，該中密度發泡緩衝 層33，係設於該高密度發泡緩衝層31與該低密度發泡緩衝 層32之間，各緩衝層31、32、33間同樣設有黏著層34，並 利用熱壓固定成型。 上述各實施例中，該高密度發泡緩衝層係位於該緩衝包 裝結構之外側，可藉由該高密度發泡緩衝層提高整體硬度， 可減少因撞擊所受之傷害以及被穿透之可能性，同時可提供 較佳之支撐力，並利用密度低於高密度發泡緩衝層之低密度 5 M392811 發泡緩衝層及/或中密度發泡緩衝層提供適當之緩衝力，如第 五圖所示，藉由該緩衝包裝結構3具有上述三層式緩衝層結 構，以提供包裝品2最佳之保護效果。 綜上所述，本創作提供一較佳可行之緩衝包裝結構，爰 依法提呈新型專利之申請；本創作之技術内容及技術特點已 揭示如上，然而熟悉本項技術之人士仍可能基於本創作之揭 示而作各種不背離本案創作精神之替換及修飾。因此，本創 作之保護範圍應不限於實施例所揭示者，而應包括各種不背 離本創作之替換及修飾，並為以下之申請專利範圍所涵蓋。 【圖式簡單說明】 第一圖係為習有緩衝發泡材之結構立體圖。 第二圖係為習有多個緩衝發泡材組合成一體之結構立體 圖。 第三圖係為本創作中緩衝包裝結構第一實施例之結構示 意圖。 第四圖係為本創作中緩衝包裝結構第二實施例之結構示 意圖。 第五圖係為本創作中緩衝包裝結構與包裝品之結構立體 圖。 M392811 【主要元件符號說明】 緩衝發泡材1 包裝品2 緩衝包裝結構3 高密度發泡緩衝層31 低密度發泡緩衝層32 中密度發泡緩衝層33 黏著層34M392811 V. New description: [New technical field] This creation is about a cushioning packaging structure, which aims to provide a cushioning packaging structure that can balance hardness and cushioning force. [Prior Art] As far as the production and sales types of information electronic products are concerned, most of them are production, assembly and distribution of products at different locations, so that parts or semi-finished products of information electric and child products must be in the processing plant. Or between manufacturers. Since the shipments of electronic products are often very large, in order to save the logistics cost of parts or semi-finished products, most parts or semi-finished products are packaged together and shipped together. However, multiple parts or semi-finished products are packaged together, so that the products can easily collide with each other and be damaged during transportation, and the information electronic products are not only high in precision but also expensive in unit price, for example, the LCD screen of the LCD screen is not modular and cannot withstand External impact or large force. Therefore, 'protective measures* must be taken into account when packaging such information electronic products, such as buffers made of styrofoam (EPS), EPE foamed polyethylene '^^yethyiene Foam) or corrugated cardboard. The foam material is lost outside the product. Then the product is placed together with the cushioning material in the packaging box to absorb the impact force from the outside during the transportation process by using the cushioning material, so as to ensure the quality and integrity of the product after leaving the factory. As shown in the first figure, it is a cushioning foam material 1 made of a low-density foaming material. The low-density foaming material has a good cushioning effect. In use, the personnel can wait for packaging. The volume of the material is required, and the buffer foam 1 is appropriately cut; although the low-density foam has a good buffering effect, '3 M392811 is easy to be punctured due to low density, and the thickness is thinned after the load is loaded. It causes the package to be easily slipped and rubbed during transportation. When package 2 is low in earthquake resistance, for example, high-precision information electronic products are very afraid of collision, so the packaging material must have sufficient hardness to provide good anti-collision protection, as shown in the second figure. The personnel must first overlap a plurality of cushioning foam materials 1 as shown in the first figure until the hardness is sufficient for the subsequent packaging operation. However, most of the layer of buffered foam material 1 will cause the overall volume after packaging to become very large and occupy a large space, especially for the exporter, the storage space of one container is fixed, and the volume of the buffered foam material 1 is increased. Relatively, the storage volume of the container is reduced, and the freight cost is increased. [New content] In view of this, the main purpose of the "buffer packaging structure" of this creation is to provide a cushioning packaging structure that combines hardness and cushioning force. In order to achieve the above object, the buffer packaging structure of the present invention is provided with at least: a high-density foaming buffer layer, a low-density foaming buffer layer, and a medium-density foaming buffer layer, and the high-density foaming buffer layer is located in the buffer packaging structure. On the outer side, the high-density foaming buffer layer can be used to improve the overall hardness, thereby reducing the damage caused by the impact and the possibility of being penetrated, and utilizing the low-density foaming buffer having a lower density than the high-density foaming buffer layer. The layer and/or medium density foaming buffer layer provides a suitable cushioning force to provide optimum protection of the package. [Embodiment] For the characteristics of this creation, please refer to the drawings and detailed description of the embodiment and M392811 is clearly understood. As shown in the first embodiment of the third figure, the buffer packaging structure 3 includes at least one high-density foaming buffer layer 31 made of high-density polyethylene foam material. The hardness is higher and provides better support; a low-density foaming buffer layer 32 is made of low-density polyethylene foam material, which has elasticity and provides better cushioning force, and is set at the height a density foaming buffer layer 31 - side; and a - medium density foaming buffer layer 33 made of a medium density polyethylene foaming material, which is disposed on the low density foaming buffer layer 32 relative to the high density The other side of the foam cushion lip 31. The overall buffer packaging structure 3 is a high-density foaming buffer layer 31, a low-density foaming buffer layer 32, and a medium-density foaming buffer layer 33 from top to bottom, and further disposed between the buffer layers 31, 32, and 33. The adhesive layer 34 is used for fixing the buffer layers 31, 32, and 33 by hot pressing. Furthermore, as shown in the fourth figure, a second embodiment of the present invention, the buffer package structure 3 also includes a density foaming buffer layer 31, a low density foaming buffer layer 32, and a medium density foaming buffer. The layer 33, wherein the medium density foaming buffer layer 33 is disposed between the high density foaming buffer layer 31 and the low density foaming buffer layer 32, and the buffer layers 31, 32, and 33 are also provided with adhesion. Layer 34 is fixed by hot pressing. In the above embodiments, the high-density foaming buffer layer is located on the outer side of the buffer packaging structure, and the high-density foaming buffer layer can improve the overall hardness, thereby reducing damage caused by impact and being penetrated. Properties, while providing better support, and using a low density 5 M392811 foaming buffer layer and / or medium density foaming buffer layer with a lower density than the high density foaming buffer layer to provide appropriate cushioning force, as shown in Figure 5. It is shown that the buffer package structure 3 has the above three-layer buffer layer structure to provide the best protection effect of the package 2.
