Description
本發明係相關於一種複合式儲液桶，尤指一種可減少殘留液體量的複合式儲液桶。The invention relates to a composite liquid storage tank, in particular to a composite liquid storage tank capable of reducing the amount of residual liquid.
一般而言，工業產品生產過程中所需要的藥液會利用特定儲液桶儲存，以避免儲液桶被藥液腐蝕或受到外力破壞而漏液。在面板產業或半導體領域中，對於藥液(例如光阻液)的純淨度要求相當高。在面板製程中通常是利用泵來抽吸或排氣壓送方式以管件將藥液從儲液桶中吸取出來，為了避免吸取藥液的過程中有空氣伴隨藥液被吸出，當藥液的液面在儲液桶中下降到一定高度時，自動化製程會停止吸取藥液，並更換新的儲液桶以繼續供應藥液。然而，由於先前技術之儲液桶的底部是一平面，上述吸取方式會使大量藥液殘留於儲液桶內，進而增加生產成本。In general, the liquid medicine required for the production process of industrial products is stored in a specific liquid storage tank to prevent the liquid storage tank from being corroded by the chemical liquid or being leaked by external force. In the panel industry or the semiconductor field, the purity of chemical liquids (such as photoresist liquids) is quite high. In the panel manufacturing process, the pump is usually used to suck or exhaust the pumping method to suck the liquid medicine from the liquid storage tank. In order to avoid the air in the process of sucking the liquid medicine, the liquid medicine is sucked out, and the liquid medicine liquid is used. When the surface drops to a certain height in the reservoir, the automated process stops taking the liquid and replaces the new reservoir to continue supplying the solution. However, since the bottom of the prior art liquid storage tank is a flat surface, the above-mentioned suction method causes a large amount of chemical liquid to remain in the liquid storage tank, thereby increasing the production cost.
本發明之目的在於提供一種可減少殘留液體量的複合式儲液桶，以解決先前技術的問題。It is an object of the present invention to provide a composite liquid storage tank which can reduce the amount of residual liquid to solve the problems of the prior art.

請參考第1圖，第1圖為本發明複合式儲液桶的示意圖。如第1圖所示，本發明複合式儲液桶100包含一外部容器110以及一內部容器120。內部容器120是容置於外部容器110內用以儲存液體。在本發明一實施例中，外部容器110是由金屬所製成，例如馬口鐵，而內部容器120是由樹脂所製成，較佳地，由高分子樹脂製成，例如高密度聚乙烯。外部容器110可以保護內部容器120，以避免複合式儲液桶100受到外力破壞而漏液。內部容器120可以耐腐蝕，以避免複合式儲液桶100被液體腐蝕而漏液。Please refer to FIG. 1 , which is a schematic view of a composite liquid storage tank of the present invention. As shown in FIG. 1, the composite liquid storage tank 100 of the present invention comprises an outer container 110 and an inner container 120. The inner container 120 is housed in the outer container 110 for storing liquid. In an embodiment of the invention, the outer container 110 is made of metal, such as tinplate, and the inner container 120 is made of resin, preferably made of a polymer resin, such as high density polyethylene.

The inner container 120 can be resistant to corrosion to prevent the composite liquid storage tank 100 from being corroded by liquid and leaking.
請同時參考第2圖和第3圖，並一併參考第1圖。第2圖為本發明複合式儲液桶之內部容器的底部的示意圖，第3圖為本發明複合式儲液桶之內部容器的底部之凹陷部和外部容器之底面相接觸的示意圖。如圖所示，本發明內部容器120之底部形成有複數個凹陷部122，且複數個凹陷部122是從內部容器120之底部中心向內部容器120之底部外緣輻射延伸，較佳地，從內部容器120之底部中心向外輻射延伸至內部容器120之底部外緣。由於複數個凹陷部122會和外部容器110之底面112相接觸，因此內部容器120可平穩地容置於外部容器110內，而不會傾斜。另外，複數個凹陷部122之間相互連通，其中之一凹陷部122至少包含兩相對凹陷部側面124；較佳地，更包含一凹陷部底面126連接於兩相對凹陷部側面124。為了讓液體匯流入凹陷部122，故兩相對凹陷部側面124之間的間隙是由上往下漸縮，其中之一凹陷部側面124可能為斜面、弧面或梯狀或其他型態。Please refer to both Figure 2 and Figure 3, and refer to Figure 1 together. 2 is a schematic view of the bottom of the inner container of the composite liquid storage tank of the present invention, and FIG. 3 is a schematic view of the bottom portion of the inner container of the composite liquid storage tank of the present invention in contact with the bottom surface of the outer container. As shown, a plurality of recesses 122 are formed in the bottom of the inner container 120 of the present invention, and a plurality of recesses 122 are radiated from the center of the bottom of the inner container 120 toward the outer edge of the bottom of the inner container 120, preferably, from The bottom center of the inner container 120 radiates outwardly to the bottom outer edge of the inner container 120. Since the plurality of recesses 122 are in contact with the bottom surface 112 of the outer container 110, the inner container 120 can be smoothly accommodated in the outer container 110 without tilting. In addition, a plurality of recessed portions 122 communicate with each other, wherein one of the recessed portions 122 includes at least two opposite recessed side surfaces 124; preferably, a recessed portion bottom surface 126 is coupled to the two opposite recessed side surfaces 124. In order to allow the liquid to flow into the recess 122, the gap between the two opposite recessed sides 124 is tapered from top to bottom, and one of the recessed sides 124 may be beveled, curved or stepped or otherwise.
請同時參考第4圖和第5圖，並一併參考第2圖。第4圖為本發明複合式儲液桶之內部容器於一第一角度的剖面圖，第5圖為本發明複合式儲液桶之內部容器於一第二角度的剖面圖。如圖所示，本發明內部容器120之頂部形成有一開口128，用以允許內部容器120儲存之液體被排出。內部容器120之開口128對應於複數個凹陷部122其中之一。另一方面，對應於開口128的凹陷部122具有一凹陷結構123，且凹陷結構123的面積對應於一管件(圖未示)管底面積，管件材質不拘可為軟管或硬管，凹陷結構123的面積至少等於管件管底面積，較佳地，凹陷結構123的面積大於管件管底面積，管件長度自內部容器120之頂部起算，至少超出內部容器120的底部高度，另一實施例為管件長度介於內部容器120的底部高度至凹陷部底面126，以利於用吸取方式吸取內部容器120儲存之液體時，可以將管件定位並置放於凹陷結構123中，另一實施例為凹陷結構123對應於開口128形狀(例如環狀)，以利於管件可直順地從開口128插入後直達凹陷結構123定位。Please refer to Figures 4 and 5 at the same time, and refer to Figure 2 together. 4 is a cross-sectional view of the inner container of the composite liquid storage tank of the present invention at a first angle, and FIG. 5 is a cross-sectional view of the inner container of the composite liquid storage tank of the present invention at a second angle. As shown, the top of the inner container 120 of the present invention is formed with an opening 128 for allowing liquid stored in the inner container 120 to be discharged. The opening 128 of the inner container 120 corresponds to one of the plurality of recesses 122. On the other hand, the recessed portion 122 corresponding to the opening 128 has a recessed structure 123, and the area of the recessed structure 123 corresponds to a tube bottom (not shown) tube bottom area, and the tube material is not limited to a hose or a hard tube, and the recessed structure The area of 123 is at least equal to the area of the bottom of the tube. Preferably, the area of the recess 123 is greater than the area of the bottom of the tube. The length of the tube is from the top of the inner container 120, at least beyond the height of the bottom of the inner container 120. Another embodiment is a tube. The length is between the bottom height of the inner container 120 and the bottom surface 126 of the recessed portion, so as to facilitate the suction and storage of the liquid stored in the inner container 120, the tube member can be positioned and placed in the recessed structure 123, and the other embodiment is corresponding to the recessed structure 123. The opening 128 is shaped (e.g., annular) to facilitate straight positioning of the tubular member from the opening 128 to the recessed structure 123.
依據上述配置，當本發明內部容器120儲存之液體被吸取出來時，係利用管件從凹陷結構123中吸取液體。由於複數個凹陷部122具有一預定深度且相互連通，因此當內部容器120儲存之液體的液面下降至接近內部容器120底部之位置時，凹陷部122仍可以使管件之開口浸沒在內部容器120儲存之液體的液面下，以避免空氣伴隨內部容器120儲存之液體被吸出。再者，當內部容器120儲存之液體的液面太低而無法繼續吸取液體時，由於液體大部分會殘留在複數個凹陷部122中，且複數個凹陷部122的面積只占內部容器120底部的面積的一小部分，因此本發明內部容器120內的殘留液體量會較先前技術之儲液桶的殘留液體量大幅減少。另一方面，由於凹陷部122的兩相對凹陷部側面124之間的間隙是由上往下漸縮，因此內部容器120內的殘留液體量可進一步減少，以20公升的儲液桶為例，底部為平面的先前技術，其殘液約為0.92公升，本發明的殘液量少於先前技術的一半，約為0.38公升。According to the above configuration, when the liquid stored in the inner container 120 of the present invention is sucked out, the liquid is sucked from the recessed structure 123 by the tube member. Since the plurality of recessed portions 122 have a predetermined depth and communicate with each other, the recessed portion 122 can still immerse the opening of the tubular member in the inner container 120 when the liquid level of the liquid stored in the inner container 120 drops to a position close to the bottom of the inner container 120. The liquid level of the stored liquid is removed to prevent the air from being sucked out by the liquid stored in the inner container 120. Moreover, when the liquid level of the liquid stored in the inner container 120 is too low to continue to suck the liquid, most of the liquid remains in the plurality of recesses 122, and the area of the plurality of recesses 122 only occupies the bottom of the inner container 120. A small portion of the area, therefore, the amount of residual liquid in the inner container 120 of the present invention is substantially reduced compared to the amount of residual liquid in the prior art reservoir. On the other hand, since the gap between the opposite recessed side faces 124 of the recessed portion 122 is tapered from the top to the bottom, the amount of residual liquid in the inner container 120 can be further reduced, for example, a 20 liter storage tank. The prior art with a flat bottom is about 0.92 liters of residual liquid, and the residual liquid amount of the present invention is less than half of the prior art, about 0.38 liters.
另外，在上述實施例中，複數個凹陷部122是以十字形、賓士形或星形從內部容器120之底部中心向內部容器120之底部外緣輻射延伸，但本發明不以此為限。在本發明其他實施例中，內部容器120之底部可以形成有其他數量的凹陷部(例如兩個、三個或五個)，且凹陷部並不限於對稱配置。In addition, in the above embodiment, the plurality of recesses 122 are radiated from the center of the bottom of the inner container 120 to the outer edge of the bottom of the inner container 120 in a cross shape, a perician shape or a star shape, but the invention is not limited thereto. . In other embodiments of the invention, the bottom of the inner container 120 may be formed with other numbers of depressions (eg, two, three, or five), and the depressions are not limited to a symmetric configuration.
相較於先前技術，本發明複合式儲液桶具有金屬製的外部容器及高分子樹脂製的內部容器，以提高複合式儲液桶的整體強度和耐腐蝕度。再者，本發明複合式儲液桶的內部容器於底部形成有複數個凹陷部，且複數個凹陷部從內部容器之底部中心向內部容器之底部外緣輻射延伸，內部容器之凹陷部不但可以使內部容器平穩地容置於外部容器內，且可以在利用管件吸取內部容器儲存之液體時減少內部容器內的殘留液體量，確能達到減少生產成本，更可因減少殘液量而減少塑膠包材之需求數量，進而達成減少廢棄物、節能減廢之訴求。 以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。Compared with the prior art, the composite liquid storage tank of the present invention has a metal outer container and an inner container made of a polymer resin to improve the overall strength and corrosion resistance of the composite liquid storage tank. Furthermore, the inner container of the composite liquid storage tank of the present invention is formed with a plurality of concave portions at the bottom, and a plurality of concave portions radiate from the center of the bottom of the inner container to the outer edge of the bottom of the inner container, and the concave portion of the inner container can not only The inner container is smoothly accommodated in the outer container, and the amount of residual liquid in the inner container can be reduced when the liquid stored in the inner container is taken up by the pipe member, so that the production cost can be reduced, and the plastic can be reduced by reducing the amount of residual liquid. The demand for packaging materials, in turn, to reduce waste, energy saving and waste reduction. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
