201127714 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種隔熱容器、製造隔熱容器之方法及 裝置，尤其係關於一種由高發泡倍率之發泡材料製得之隔 熱容器、製造隔熱容器之方法及裝置。 【先前技術】 免洗杯廣泛使用於冷、熱飲盛裝，以提供簡便使用及 免洗拋棄之功能，但習知免洗紙杯不具有隔熱及保溫功 *能，如使用於盛裝高溫熱湯或熱飲之場合，則會有烫手而 無法端盛之缺點；而市售常見的免洗塑膠杯，材料剛性強， 但不具有隔熱及保溫功能，且成本較高，環保性低。 亦有於紙杯材料表面直接塗佈發泡劑，再經折疊成 型，最後經加溫發泡製程，使紙杯表面直接發泡而形成紙 杯内外之隔熱保溫結構。以第200914334號台灣專利為 例，其係揭露於紙容器或半成品紙板塗佈發泡材料後，成 $ 型為紙容器，以低於起始發泡溫度烘乾以形成未發泡層， 於紙容器内緣彼附可耐高溫與環保效果之高分子聚對苯二 曱酸乙二酯（簡稱PET)或高分子聚丙烯（簡稱PP)，再對該 發泡材料進行瞬間加熱發泡。此種製程之缺點為步驟複 雜、成本高、不利於產業利兩，此外，發泡材料在紙杯表 面發泡時，會使紙杯表面凹凸不平，破壞美觀，且於紙杯 表面厚度單薄沒有發泡空隙，故僅能以5倍以下之發泡倍 率形成發泡結構，發泡厚度會受限於1微米（mm)以下，熱 傳導率數據偏高，僅能提供瞬間隔熱的效果，而無法提供 111163 201127714 較佳隔熱與保溫功能。 另外，亦有針對杯體結構或特定結構之製法進行夂良 者，例如第 590114、501996、393427、424049、及 1288619 號台灣專利等，係揭示在紙杯本體外部設有凸軌槽或肋 件，並藉由外杯或套筒套設於本體外，而使該内紙杯及外 杯間具有間隙，於該間隙填充發泡劑或發泡材料並進行發 泡，藉此提供局部隔熱或保溫功能。然而，上述前案大幅 改變紙杯原有形狀，必需藉由複雜的加工形成凸執槽或肋 件，使製造成本增加，不易量產製作。而發泡劑或發泡材 料於有限空間進行發泡、或預先發泡後充填至該間隙等製 作方式，使發泡體積或形狀之控制難度大幅增加，精準度 及均勻度控制不易，且無法確保隔熱杯組之外觀形狀美觀 整齊。 另外，由於需使用凸執槽或肋件來區隔發泡空間，會 使隔熱、保溫功能僅侷限於局部，例如，凸軌槽或肋件並 無發泡材料被覆，因而使杯内盛裝熱飲之熱量直接透過這 些隔熱空隙與死角散發出來，熱傳導係數快速昇高，而讓 使用者仍會有執握燙手，以及熱量散失而無法長時間隔熱 及保溫等缺點。 因而，如何透過簡單工序以高發泡倍率之發泡材料製 備熱容器，乃成業界一亟待解決之課題。 【發明内容】 有鑑於此，本發明係提供一種以發泡>1材製得之隔熱 容器，係包括：基底，界定有中央部及位於中央部以外週 A 111163 201127714 緣之第一結合部，且該第一結合部之厚度小於該中央部之 厚度；以及由發泡片材的兩側邊對接所構成之筒形侧壁， 且於該筒形側壁上下兩端分別形成有該開口頂部及用以疊 接於該基底第一結合部的第二結合部。 於一具體實施例中，該筒形側壁表面具有複數條延伸 於該基底端與該開口頂部之間且彼此間隔的凹槽。 於本發明之隔熱容器中，為快速及穩定地結合片材以 及符合美觀上的要求，該第一結合部之厚度小於該中央部 ®之厚度。同樣地，用以對接構成該筒形侧壁之發泡片材的 兩側邊及該筒形側壁之第二結合部的厚度皆小於該筒形側 壁之厚度。當然較佳地，基底第一結合部與側壁第二結合 部之結合厚度不會明顯厚於該容器側壁而造成結合部凸 起。 舉例但非限制，當該隔熱容器之基底與筒形侧壁為相 同厚度之發泡片材時，可令第一結合部之厚度約為中央部 Φ 的一半，且第二結合部之厚度亦約為筒形側壁的一半，藉 此，可得到平坦的結合部位。 本發明之隔熱容器係由發泡材料構成，係採用物理性 發泡處理，將氣體與聚合物混和，再藉由押出機將混和有 氣體的聚合物押製為一片材，由於該聚合物一經壓出後， 該聚合物材料中的氣體隨即因無壓力的束縛而逸散於大氣 中，通常，只要選擇對食品無毒性的氣體即可，較佳地， 可選擇易揮發之氣體，如瓦斯，更具體而言，如曱烷、丙 烷或丁烷等。於實施例中，聚合物可選自聚笨乙烯 5 111163 201127714 (polystyrene，簡稱PS)、聚丙烯、聚對苯二甲酸乙二醇 酿、聚乳酸（polylacticAcid、p〇lylactide，簡稱 pla)、戍 其混合物。則該發泡材料可為選自聚苯乙烯、聚兩婦、聚 對苯二甲酸乙二醇酯、聚乳酸、或其混合物之片材。此外， 一般傳統保麗龍材質係以經發泡之聚苯乙烯顆粒為原料， 再透過重油燃燒蒸氣以製作成型，因此，除了做為原料之 已發泡顆粒因含有瓦斯及重油燃燒製作的成本較高外，其 所製得之產品較重、賴差且容易斷裂，在發泡倍率有限 的情況下，發泡顆粒間的孔隙較大亦影響保溫性能。 另一方面，為使隔熱容器具優異之剛性和隔熱保溫之 效果，該隔熱容器係以發泡倍率為]〇倍至4〇倍之發泡材

Description of the Invention: [Technical Field] The present invention relates to a heat insulating container, a method and a device for manufacturing the heat insulating container, and more particularly to a heat insulating container made of a foaming material having a high expansion ratio, Method and apparatus for making insulated containers. [Prior Art] The disposable cups are widely used in cold and hot drinks to provide easy-to-use and disposable-free functions. However, conventional disposable paper cups do not have heat insulation and heat preservation functions, such as hot soup or hot drinks. In this case, there will be shortcomings that are hot and impossible to produce; and the commercially available disposable plastic cups have strong rigidity, but do not have heat insulation and heat preservation functions, and have high cost and low environmental protection. The foaming agent is also directly coated on the surface of the paper cup material, and then folded and formed. Finally, the surface of the paper cup is directly foamed by the heating foaming process to form an insulation structure inside and outside the paper cup. Taking Taiwan Patent No. 200914334 as an example, it is disclosed in a paper container or a semi-finished paperboard coated foam material, and then formed into a paper container, which is dried at a temperature lower than the initial foaming temperature to form an unfoamed layer. The inner edge of the paper container is provided with high-molecular-weight polyethylene terephthalate (PET) or high-molecular polypropylene (PP), which can withstand high temperature and environmental protection, and the foamed material is instantaneously heated and foamed. The shortcomings of such a process are complicated steps, high cost, and unfavorable to the industry. In addition, when the foamed material is foamed on the surface of the paper cup, the surface of the paper cup is uneven, which is destructive, and the surface of the paper cup is thin and has no foaming gap. Therefore, the foamed structure can be formed only by the expansion ratio of 5 times or less, the foaming thickness is limited to 1 micrometer (mm) or less, and the thermal conductivity data is high, which can only provide the effect of instantaneous heat insulation, and cannot provide 111163. 201127714 Better insulation and insulation. In addition, there are also methods for manufacturing the cup structure or the specific structure, such as the Taiwan patents Nos. 590114, 501996, 393427, 424049, and 1288619, etc., which discloses that a rail groove or a rib member is provided outside the paper cup body. And the outer cup or the sleeve is sleeved on the outside of the body, so that there is a gap between the inner paper cup and the outer cup, and the foaming agent or the foaming material is filled in the gap and foamed, thereby providing partial heat insulation or heat preservation. Features. However, the above-mentioned predecessor greatly changes the original shape of the paper cup, and it is necessary to form a convex groove or a rib by complicated processing, which increases the manufacturing cost and is not easy to mass-produce. The blowing agent or the foaming material is foamed in a limited space, or is pre-foamed and filled into the gap, and the like, so that the control difficulty of the foaming volume or shape is greatly increased, the precision and uniformity control are not easy, and the Make sure that the shape of the insulated cups is neat and tidy. In addition, since the convex groove or rib member is required to separate the foaming space, the heat insulating and heat insulating functions are limited to a part, for example, the convex rail groove or the rib member is not covered with the foaming material, so that the cup is contained therein. The heat of the hot drink is directly emitted through these heat-insulating gaps and dead angles, and the heat transfer coefficient is rapidly increased, so that the user still has the disadvantages of holding hands and heat loss without being able to heat and keep warm for a long time. Therefore, how to prepare a heat container with a foaming material having a high expansion ratio through a simple process is an urgent problem to be solved in the industry. SUMMARY OF THE INVENTION In view of the above, the present invention provides a thermally insulated container made of a foamed material, comprising: a base defining a central portion and a first joint located at a periphery of the central portion A 111163 201127714 And a thickness of the first joint portion is smaller than a thickness of the central portion; and a cylindrical side wall formed by abutting both sides of the foamed sheet, and the opening is formed at upper and lower ends of the cylindrical side wall a top portion and a second joint portion for being attached to the first joint portion of the substrate. In one embodiment, the cylindrical sidewall surface has a plurality of grooves extending between the base end and the top of the opening and spaced apart from each other. In the insulated container of the present invention, the thickness of the first joint portion is smaller than the thickness of the central portion ® in order to quickly and stably bond the sheet and meet aesthetic requirements. Similarly, the thickness of the second joint portion of the foamed sheet for abutting the cylindrical side wall and the second side of the cylindrical side wall is smaller than the thickness of the cylindrical side wall. Of course, preferably, the combined thickness of the first joint of the base and the second joint of the side wall is not significantly thicker than the side wall of the container to cause the joint to protrude. By way of example and not limitation, when the base of the insulated container and the cylindrical side wall are foamed sheets of the same thickness, the thickness of the first joint portion is about half of the central portion Φ, and the thickness of the second joint portion is It is also about half of the cylindrical side wall, whereby a flat joint portion can be obtained. The heat insulating container of the present invention is composed of a foamed material, which is subjected to physical foaming treatment, mixing a gas with a polymer, and then extruding a gas-mixed polymer into a sheet by an extruder, due to the polymerization. After the material is extruded, the gas in the polymer material is then released into the atmosphere due to the lack of pressure. Generally, as long as a gas that is not toxic to the food is selected, preferably, a volatile gas may be selected. Such as gas, more specifically, such as decane, propane or butane. In an embodiment, the polymer may be selected from the group consisting of polystyrene 5 111163 201127714 (polystyrene, PS for short), polypropylene, polyethylene terephthalate, polylactic acid (polylactic Acid, p〇lylactide, pla) Its mixture. The foamed material may then be a sheet selected from the group consisting of polystyrene, polymethylene, polyethylene terephthalate, polylactic acid, or a mixture thereof. In addition, the conventional traditional styrofoam material is made of foamed polystyrene granules and then burned by heavy oil combustion steam. Therefore, in addition to the cost of burning the granulated particles as raw materials due to the combustion of gas and heavy oil. Higher, the products produced are heavier, poorer and easier to break. In the case of limited expansion ratio, the larger pores between the foamed particles also affect the heat preservation performance. On the other hand, in order to make the heat-insulating container have excellent rigidity and heat insulation effect, the heat-insulating container is prepared by foaming materials having a foaming ratio of 4 times to 4 times and is 20 times to 40 times. The foaming magnification is better. • The control system of the doubling rate is well known to those of ordinary skill in the art and will not be mentioned here. The insulated container of the present invention has a thickness of from 5 to 3 microns, more than 3 microns. Specifically, the thickness of the central portion of the substrate and the side wall of the cylindrical shape is preferably 2 to 3 μm. In the embodiment, the thickness of the foam material prepared by the following: the foaming material ratio is 10 times to 40 times [: = the rigidity of the sheet (four), and therefore, the plurality of concave and convex materials are used for the foaming of the butt joints. Formed on both sides of the sheet. = In the usual case, the 凹槽(4) is insulated from the scales of the two, and the grooves are also arranged differently. Example 2 = 7 = the base end is open, extending radially or the other is "1163" 6 201127714 In the embodiment, the rim of the opening portion of the insulated container is formed by partially shallowing and bending a part of the foamed material of the side wall.

In a specific embodiment of the method of the present invention, the side wall region of the second foamed sheet has a plurality of grooves extending between the second joint portion forming portion and the open top portion and spaced apart from each other. In the method of the present invention, the first and second foaming materials used are foamed. The rate is 10 to 40 times, and the thickness of the side wall portion and the central portion is 1.5 to 3 μm and preferably 2 to 3 μm. In the example, the first foamed sheet may be circular or polygonal, preferably circular, square or rectangular; and the second foamed sheet may be square or rectangular. The method of the present invention can be further included in the docking step. The step of the step is to fold the predetermined portion of the opening to the outer edge of the opening, and to extend the rim of the 163 7 201127714. In another aspect, the present invention provides a device for preparing the insulated container of the present invention for tying a second joint of the first joint portion of the base and the cylindrical side wall, the device comprising: a support sleeve a mold having a flat surface at one end for arranging the substrate and corresponding in size to the substrate area, the support mold being disposed in the cylindrical side wall of the substrate not yet laminated, and having a length shorter than the cylindrical side wall; The abutting member is provided with a plurality of rollers for bending the second joint portion of the cylindrical side wall and abutting against the first joint portion of the base; and the first heater is disposed on the flat mold of the support sleeve The side is heated to heat the substrate.

The substrate 12 is composed of the first foamed sheet material, and the foamed material may be polystyrene (10) or the thickness of the sheet material is 丨 5 to 3 μm, preferably 2 to 3 In the case of the esoteric application, the first foaming is not limited. The shape of the first foamed sheet can be roughly; 2 round or square square cup or round cup. Along the first foamed sheet; the appearance of the first foamed sheet is superficially treated with a predetermined width, and the shape of the wheel is the same as that of the original shape, and the original 嶋度方, 川 163 9 201127714 A case, the stencil mold is applied to (4) The definition has the effect of Zhuo Qiu~,,, Zhiyue Yuecai 2, 2, and the pressure of % to the outside of the second W-joining portion forming portions 22, 22, which achieves the effect of shallow layering, in addition, The heating can be applied to the first foamed sheet 2 =:, when: the first ... and the fourth (figure): the layer = = the forming portion and the top portion of the opening portion of the cap portion of the opening forming the insulated container after the first joint and opening top. 13. The foamed sheet 3 is formed of a foamed material from a cylindrical side wall sheet 3 for forming the heat insulating cup 1, the foamed material 3 = sputum (PS) or polylactic acid (PLA), The thickness of the sheet is from .5 to ... preferably from 2 to 3 μm. Referring to Figures 3A to 3D, the second foamed sheet 3 may be rectangular or fan-shaped. When the second two-bubble sheet is rectangular (as shown in the figure), the diameter of the cup is substantially the same as the bottom of the cup. 'When the second foamed sheet is fan-shaped (as in the redundancy diagram), the mouth of the cup is more than the bottom of the cup. In the embodiment shown in FIGS. 3A and 3C, the rim is formed along the outer shape of the second foamed moon material 3, and the three sides are shallowly processed by a predetermined width to form the first The second joint forming portion 32, the loop portions 33 and 3, and the side wall portion 31 for maintaining the thickness of the original sheet. In a specific embodiment, a pressure is applied to the second foam sheet #3 by a mold to define two loop portions 33, 34 and a second joint portion 3 other than the side wall region 31. 2 thinning to achieve the effect of shallow stratification. Of course, it is possible to apply a pure heating to the second foamed sheet 3 for shallow stratification at the time of molding. In another aspect, reference is made to the 3B inverse 3D diagram along the second hair H1163 10 201127714 • the bubble sheet 3 outside the shape wheel temple, (4) the second joint portion forming portion %, the loop portions 33 and 34, and The top portion predetermined portion 35 is opened. β is a rigid sheet having a j degree of 1.5 to 3 U meters prepared by a foaming material having a foaming ratio of 1 to 4 times, so that it is developed in the present invention. The high foaming ratio and the thermal insulation property are better. The container 2 is still prepared with a lower foaming and thickness (four) sheet. Exploring the reason, the main difficulty is that if you want to prepare a high foaming ratio # and a thicker insulated container, it is extremely difficult to heat the sheet to make it eight, = the sheet melts or (4) the joint strength is not good, The paradox broke due to the sheet just folded into the bubble sheet. In addition, the past foam sheet needs to be borrowed! Since: the molding machine rotates the sheet while heating the sheet..."^ The parts are generally in vain in the industry even if the heating method or the manufacturing equipment is improved. However, as shown in Figs. 3A to 3D of the present invention, a plurality of surnames / / > 32 are formed on the surface of the sheet 3, and the top portion of the opening is formed by the joint portions at the ends of the crucible 35, and the grooves are spaced apart from each other. The groove 36 is bent by the temple groove 36 as a foamed sheet to form the cylindrical side wall 13 of the heat insulation extension 1, and the number of 36 is not special U first The foamed sheet 3 is matched with the first hair, and further, as shown in Figures 3A and 3B, the (four) shaped heart is equally spaced, or ♦, such as the first 凹 ^ concave # 36 The second joint portion is formed to extend radially in a radial direction. And finally, the insulating container is finished τ ° 豕 groove 3 ό can form π 1 ΠΙ 63 201127714 on the outer side surface of the cylindrical side wall 13, or formed on the cylindrical side wall 13 for housing the elder. The inner surface of the σ contact. Further, in practice, a plurality of grooves 36 such as longitudinal embossing or longitudinal creases may be formed by applying a force or heat-treating the second foamed sheet 3 by a mold. The formation of the aforementioned second joint portion and the loop portion may be completed simultaneously or sequentially with the formation of the groove. Then, the second foamed sheet 3 is bent, the loop portions 33 and 34 are overlapped with each other, and the two loop portions 33 and 34 are fixed by ultrasonic bonding to make the second foam sheet The material 3 forms a cylindrical structure through which both ends penetrate, that is, the cylindrical side wall 13 of the "black insulating cup 1. In the present invention, although the sheet expansion ratio is two to 10 to 4 Å, the thickness of the side wall portion and the central portion is found to be 15 to j μm, and the thickness of the loop portions 33 and 34 after ringing falls. Between 5 and 10 μm, the thickness after the plucking is preferably about the same as that of the foamed sheet, and it is not necessary to start from one end of the sheet and gradually overlap the other end to heat and fit. After overlapping, the ultrasonic bonding is directly applied to reduce the enthalpy generated by the gradual heating bonding, and /IT ^ <Le-hybrid portion forming portion 22" The second bonding portion forming portion of the foamed sheet 3 32 overlap each other, and the hot air is heated and bonded or the simple ultrasonic wave is applied, and the second joint forming portion 32 of the foaming material 3 is formed with the first foaming sheet.
