Description

絕熱容器的製造方法Method for manufacturing thermal insulation container

本發明係關於一種絕熱容器的製造方法。The present invention relates to a method for manufacturing an insulating container.

以往，已知一種絕熱容器，具有一端開有開口的金屬製外容器及內容器，且在內容器收納於外容器內側的狀態下彼此開口端側相互接合，而於外容器與內容器之間設有真空絕熱層。如此的絕熱容器廣泛運用於飲料容器，如具有保溫和保冷功能的水瓶和水杯，以及具有保溫功能的食品容器和炊具(例如，美國專利申請公開號2019/0231145號)。In the past, an insulated container is known, which has a metal outer container with an opening at one end and an inner container, and the open ends of the inner container are connected to each other when the inner container is stored inside the outer container, and a vacuum insulation layer is provided between the outer container and the inner container. Such insulated containers are widely used in beverage containers, such as water bottles and cups with heat preservation and cold preservation functions, and food containers and cookware with heat preservation functions (for example, U.S. Patent Application Publication No. 2019/0231145).

承上，在上述習知的絕熱容器中，外容器和內容器的開口端相互對接，對接處被熔接在一起。此外，通過在減壓(真空)室中用蠟質材料封住外容器底部的排氣用的孔部，藉此在外容器和內容器之間形成一個真空絕緣層。As described above, in the above-mentioned known insulated container, the open ends of the outer container and the inner container are butted against each other and the butted parts are welded together. In addition, by sealing the exhaust hole at the bottom of the outer container with a wax material in a decompression (vacuum) chamber, a vacuum insulation layer is formed between the outer container and the inner container.

另一方面，習知技術提出了一種通過在減壓下熔接以密封外容器上用於排氣的槽縫來形成真空保溫層的方法。On the other hand, the prior art proposes a method of forming a vacuum insulation layer by welding under reduced pressure to seal a groove for exhausting gas on an outer container.

由於藉由熔接而密封的槽縫，其熔接痕跡會使其變得不雅觀，另一方面，如果減少槽縫的寬度或長度，以使焊接痕跡不那麼明顯，則透過狹縫進行排氣所需的時間就會增加，製造效率亦降低。因此，本發明是鑒於上述習知情況而提出的，目的是提供一種絕熱容器的製造方法，可以不用設置排氣用槽縫就可在外容器及內容器之間形成真空絕熱層。Since the weld marks of the slits sealed by welding make them unsightly, on the other hand, if the width or length of the slits is reduced to make the weld marks less obvious, the time required for exhausting through the slits will increase, and the manufacturing efficiency will also decrease. Therefore, the present invention is proposed in view of the above-mentioned known situation, and its purpose is to provide a method for manufacturing an insulated container, which can form a vacuum insulation layer between an outer container and an inner container without providing a slit for exhausting.

本發明之一目的，係提供一種絕熱容器的製造方法，其中，一絕熱容器具有一端設有開口之金屬製的一外容器及一內容器，且以該內容器收納於該外容器內側的狀態，該外容器及該內容器彼此的開口端會相互接合，該外容器及該內容器之間設有一真空絕熱層，在減壓的情況下，將構成該外容器之其中一構件及構成該外容器之另一構件以熔接的方式相接合，以在該外容器與該內容器之間形成該真空絕熱層。One object of the present invention is to provide a method for manufacturing an insulating container, wherein the insulating container has an outer container made of metal with an opening at one end and an inner container, and when the inner container is accommodated inside the outer container, the open ends of the outer container and the inner container are joined to each other, and a vacuum insulating layer is provided between the outer container and the inner container. Under reduced pressure, one component constituting the outer container and another component constituting the outer container are joined by welding to form the vacuum insulating layer between the outer container and the inner container.

可選地，在減壓狀態下，將構成該外容器之底部的其中一構件及構成該外容器之軀幹部的另一構件以熔接的方式相接合。Optionally, under a depressurized state, one of the components constituting the bottom of the outer container and another component constituting the trunk of the outer container are joined by welding.

可選地，在減壓狀態下，將構成該外容器之肩部的其中一構件及構成該外容器之軀幹部的另一構件以熔接的方式相接合。Optionally, under a depressurized state, one of the components constituting the shoulder of the outer container and another component constituting the trunk of the outer container are joined together by welding.

本發明之另一目的，係提供一種絕熱容器的製造方法，其中，一絕熱容器具有一端設有開口之金屬製的一外容器及一內容器，且以該內容器收納於該外容器內側的狀態，該外容器及該內容器彼此的開口端會相互接合，於該外容器及該內容器之間設有一真空絕熱層，在減壓的情況下，將構成該外容器之其中一構件及構成該內容器之另一構件以熔接的方式相接合，以在該外容器與該內容器之間形成該真空絕熱層。Another object of the present invention is to provide a method for manufacturing an insulating container, wherein an insulating container has an outer container made of metal with an opening at one end and an inner container, and when the inner container is accommodated inside the outer container, the open ends of the outer container and the inner container are joined to each other, and a vacuum insulating layer is provided between the outer container and the inner container. Under reduced pressure, one component constituting the outer container and another component constituting the inner container are joined by welding to form the vacuum insulating layer between the outer container and the inner container.

可選地，該其中一構件與該另一構件係以雷射熔接的方式相接合。Optionally, the one component and the other component are joined together by laser welding.

可選地，該外容器及該內容器係由鈦、鋁、鎂或其合金所製成。Optionally, the outer container and the inner container are made of titanium, aluminum, magnesium or their alloys.

如上所述，本發明可提供一種絕熱容器的製造方法，可以不用設置排氣用槽縫就可在外容器及內容器之間形成真空絕熱層。As described above, the present invention can provide a method for manufacturing an insulating container, which can form a vacuum insulating layer between an outer container and an inner container without providing a slit for exhaust.

為便 貴審查委員能對本發明目的、技術特徵及其功效，做更進一步之認識與瞭解，茲舉實施例配合圖式，詳細說明如下：In order to help you, the review committee, to have a deeper understanding of the purpose, technical features and effects of the present invention, the following embodiments are provided with accompanying drawings for detailed description:

以下，就本發明的實施例，參考圖式加以詳細說明。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(第一實施例)(First Embodiment)

首先，就本發明第一實施例，例如圖1至圖3所示之絕熱容器1A及其製造方法加以說明。First, the first embodiment of the present invention, for example, the insulated container 1A shown in Figures 1 to 3 and its manufacturing method will be described.

其中，圖1係本發明之第一實施例的絕熱容器1A之立體圖；圖2係圖1所示絕熱容器1A之構造之剖面圖；圖3係圖1所示絕熱容器1A之構造之分解剖面圖。1 is a three-dimensional diagram of an insulating container 1A of the first embodiment of the present invention; FIG. 2 is a cross-sectional diagram of the structure of the insulating container 1A shown in FIG. 1; and FIG. 3 is an exploded cross-sectional diagram of the structure of the insulating container 1A shown in FIG. 1.

請參閱圖1至圖3所示，本實施例之絕熱容器1A具有一端開有開口的金屬製外容器2及內容器3，絕熱容器1A以該內容器3收納於該外容器2內側的狀態，使該外容器2及該內容器3彼此的開口端側相互接合，並於該外容器2及該內容器3之間設有真空絕熱層4。As shown in FIGS. 1 to 3 , the insulating container 1A of this embodiment comprises a metal outer container 2 with an opening at one end and an inner container 3. The insulating container 1A is in a state where the inner container 3 is accommodated inside the outer container 2, so that the open ends of the outer container 2 and the inner container 3 are joined to each other, and a vacuum insulating layer 4 is provided between the outer container 2 and the inner container 3.

藉由具有如上所述之真空絕熱構造，可賦予本實施例的絕熱容器1A保溫或保冷的功能，又，在絕熱容器1A中，使外容器2及內容器3經常處於被施加有內壓力(真空壓力)及外壓力(大氣壓力)之差值的狀態，可增加外容器2及內容器3的機械強度。藉此，即使外容器2與內容器3的板金厚度很薄，仍可提高絕熱容器1A的剛性，更可達成絕熱容器1A的輕量化。By having the vacuum insulation structure as described above, the insulation container 1A of this embodiment can be given the function of keeping warm or cold. In addition, in the insulation container 1A, the outer container 2 and the inner container 3 are always in a state where the difference between the internal pressure (vacuum pressure) and the external pressure (atmospheric pressure) is applied, which can increase the mechanical strength of the outer container 2 and the inner container 3. In this way, even if the sheet metal thickness of the outer container 2 and the inner container 3 is very thin, the rigidity of the insulation container 1A can be improved, and the insulation container 1A can be made lighter.

本實施例的絕熱容器1A可以是一種帶蓋容器的容器本體，藉由可對該絕熱容器1A螺合拆裝的蓋體(未圖示)，以開關絕熱容器1A的上端開口部。The insulated container 1A of this embodiment may be a container body with a cover, and the upper end opening of the insulated container 1A can be opened and closed by a cover (not shown) that can be screwed and detached from the insulated container 1A.

本實施例的絕熱容器1A雖然具有全體呈有底大致圓筒狀的外觀形狀，但本發明對絕熱容器1A的外觀形狀配合所需尺寸或設計等可適當變化並無特別限制。又，亦可在外容器2的外表面施加塗裝或印刷等。Although the insulated container 1A of this embodiment has an overall bottomed cylindrical appearance, the present invention is not particularly limited to the appearance of the insulated container 1A and can be appropriately changed to match the required size or design. In addition, the outer surface of the outer container 2 may be painted or printed.

需要特別說明，本實施例的絕熱容器1A，外容器2具有為其中一構件的上側構件2a、以及為另一構件的下側構件2b。其中，上側構件2a係構成外容器2的軀幹部、肩部及頭頸部，下側構件2b係構成外容器2的底部及軀幹部。It is particularly important to explain that the outer container 2 of the insulated container 1A of this embodiment has an upper side member 2a as one of the components and a lower side member 2b as the other component. The upper side member 2a constitutes the trunk, shoulder and head and neck of the outer container 2, and the lower side member 2b constitutes the bottom and trunk of the outer container 2.

本實施例的絕熱容器1A在內容器3收容於上側構件2a之內側的狀態下，將上側構件2a及內容器3的開口端彼此對接，並將對接部分藉由熔接接合。In the insulated container 1A of this embodiment, when the inner container 3 is accommodated inside the upper member 2a, the opening ends of the upper member 2a and the inner container 3 are butted against each other, and the butted portions are joined by welding.

又，本實施例之絕熱容器1A係在將下側構件2b的上端相對於與內容器3接合之上側構件2a嵌入至內側的狀態下，藉由熔接將上側構件2a與下側構件2b之間接合，藉此構成外容器2。In the insulated container 1A of this embodiment, the upper end of the lower member 2b is inserted into the upper member 2a joined to the inner container 3, and the upper member 2a and the lower member 2b are joined by welding to form the outer container 2.

圖2雖圖示有上側構件2a與內容器3的接合部分(邊界)、以及上側構件2a與下側構件2b的接合部分(邊界)，但是在接合之後，藉由熔接來熔融該等接合部分，會於接合部分整圈形成焊珠，又，可透過於熔接後對該焊珠進行研磨及拋光加工以完成平滑表面。Although FIG. 2 illustrates the joint portion (boundary) between the upper member 2a and the inner container 3, and the joint portion (boundary) between the upper member 2a and the lower member 2b, after joining, the joint portions are melted by welding, and weld beads are formed around the entire joint portion. Furthermore, the weld beads can be ground and polished after welding to complete a smooth surface.

除了一般使用的不鏽鋼之外，亦可使用鈦、鋁、鎂或其等之合金來製作外容器2及內容器3。又，熔接接合可使用雷射熔接等熔接方法。In addition to commonly used stainless steel, titanium, aluminum, magnesium or alloys thereof may be used to make the outer container 2 and the inner container 3. In addition, welding methods such as laser welding may be used for welding.

本實施例之絕熱容器1A係在減壓狀態下，藉由熔接接合構成外容器2的上側構件2a與下側構件2b，在外容器2與內容器3之間形成真空絕熱層4。The insulating container 1A of this embodiment forms a vacuum insulating layer 4 between the outer container 2 and the inner container 3 by welding the upper member 2a and the lower member 2b constituting the outer container 2 under reduced pressure.

具體而言，在製造該絕熱容器1A時，係於減壓(真空吸引)之腔室內，使下側構件2b的上端成為相對於上側構件2a更嵌入至內側的狀態，在此狀態下透過設置於腔室的窗部自外部對腔室內的絕熱容器1A照射雷射光。Specifically, when manufacturing the insulating container 1A, the upper end of the lower member 2b is made to be more embedded inward relative to the upper member 2a in a depressurized (vacuum suction) chamber. In this state, the insulating container 1A in the chamber is irradiated with laser light from the outside through a window provided in the chamber.

此時，一邊將絕熱容器1A繞中心軸旋轉，一邊沿著上側構件2a與下側構件2b的邊界照射雷射光，藉此，可精確地接合上側構件2a與下側構件2b。At this time, while rotating the insulating container 1A around the central axis, laser light is irradiated along the boundary between the upper member 2a and the lower member 2b, thereby accurately joining the upper member 2a and the lower member 2b.

要特別說明的是，習知技術中於經減壓(真空吸引)的腔室內對設置於外容器之底面的排氣用孔部以蠟封材料密封的方法，由於需要使蠟封材料融化，因此需要加熱絕熱容器。It should be particularly noted that the method of sealing the exhaust hole provided on the bottom surface of the outer container with a wax sealant in a depressurized (vacuum suction) chamber in the prior art requires heating the insulating container because the wax sealant needs to be melted.

例如，將較不鏽鋼輕的純鈦使用來製作外容器及內容器時，適合純鈦的蠟封材料必須加熱至800°C左右使其熔融。這樣的情況下退火會造成外容器及內容器機械強度低落，因此難以保持與同樣厚度不鏽鋼一樣的機械強度。For example, when pure titanium, which is lighter than stainless steel, is used to make outer and inner containers, wax sealants suitable for pure titanium must be heated to about 800°C to melt them. In this case, annealing will cause the mechanical strength of the outer and inner containers to decrease, making it difficult to maintain the same mechanical strength as stainless steel of the same thickness.

因此，習知的密封方法相較於使用不鏽鋼的情況，必須加厚外容器及內容器的厚度以確保外容器及內容器的機械強度。Therefore, the conventional sealing method requires thicker outer and inner containers than stainless steel to ensure mechanical strength of the outer and inner containers.

相較於上述習知技術，本實施例的絕熱容器1A的製造方法，不需要加熱絕熱容器1A，在使用純鈦製作外容器2及內容器3時不需要退火，因此，可薄化外容器2及內容器3的厚度，另外，亦不需要加熱絕熱容器1A所需要的電力及時間。Compared to the above-mentioned known technology, the manufacturing method of the insulating container 1A of the present embodiment does not need to heat the insulating container 1A, and does not require annealing when pure titanium is used to make the outer container 2 and the inner container 3. Therefore, the thickness of the outer container 2 and the inner container 3 can be thinned. In addition, the electricity and time required for heating the insulating container 1A are not required.

如上所述，本實施例的絕熱容器1A的製造方法可在不設置排氣用之槽縫的情況下，在外容器2與內容器3之間形成真空絕熱層4。As described above, the manufacturing method of the insulated container 1A of this embodiment can form the vacuum insulation layer 4 between the outer container 2 and the inner container 3 without providing a groove for exhaust.

又，本實施例的絕熱容器1A的製造方法比起例如在下側構件2b之底面一部分設置排氣用槽縫的情況，可自上側構件2a與下側構件2b之間整圈排氣，因此，可縮短排氣所需要的時間，而可縮短平均製造時間。Furthermore, the manufacturing method of the insulated container 1A of this embodiment can exhaust air from the entire circle between the upper member 2a and the lower member 2b, compared to, for example, providing an exhaust groove on a portion of the bottom surface of the lower member 2b. Therefore, the time required for exhaust can be shortened, and the average manufacturing time can be shortened.

然而，雖然本實施例的絕熱容器1A的製造方法係例示如上所述在減壓(真空吸引)的腔室內，將上側構件2a與下側構件2b之間整圈接合，但亦可將上側構件2a與下側構件2b之間留下一部分的未熔接部，並且將其等在大氣壓力中熔接接合，而在減壓狀態下，藉由熔接將該未熔接部藉由熔接密封，以在外容器2及內容器3之間形成真空絕熱層4。However, although the manufacturing method of the insulating container 1A of the present embodiment illustrates the method of joining the upper member 2a and the lower member 2b in a completely circle in a depressurized (vacuum suction) chamber as described above, it is also possible to leave a portion of the unwelded portion between the upper member 2a and the lower member 2b, and weld them together under atmospheric pressure, and then seal the unwelded portion by welding under a depressurized state to form a vacuum insulating layer 4 between the outer container 2 and the inner container 3.

具體而言，在密封該未熔接部時，係將密封前的絕熱容器1A收納於已減壓(真空吸引)之腔室內，並透過未熔接部使外容器2與內容器3之間排氣，在此狀態下，透過設置於腔室的窗部自外部對腔室內的絕熱容器1A照射雷射光。Specifically, when sealing the unwelded portion, the insulating container 1A before sealing is placed in a depressurized (vacuum suction) chamber, and air is exhausted from between the outer container 2 and the inner container 3 through the unwelded portion. In this state, the insulating container 1A in the chamber is irradiated with laser light from the outside through a window provided in the chamber.

此時可一邊將絕熱容器1A繞中心軸旋轉，一邊沿未熔接部照射雷射光，藉此可精確密封未熔接部。At this time, the unwelded portion can be accurately sealed by irradiating the unwelded portion with laser light while rotating the insulating container 1A around the central axis.

又，本實施例之絕熱容器1A的製造方法，亦可將上側構件2a與內容器3之間留下一部分的未熔接部，並在減壓狀態下，藉由熔接將該未熔接部藉由熔接密封，藉此在外容器2及內容器3之間形成真空絕熱層4。Furthermore, the manufacturing method of the insulating container 1A of the present embodiment may also leave a portion of the unwelded portion between the upper member 2a and the inner container 3, and seal the unwelded portion by welding under reduced pressure, thereby forming a vacuum insulating layer 4 between the outer container 2 and the inner container 3.

(第二實施例)(Second embodiment)

接著，說明如圖4至圖6所示之本發明之第二實施例之絕熱容器1B及其製造方法。Next, the insulated container 1B and its manufacturing method according to the second embodiment of the present invention as shown in FIGS. 4 to 6 will be described.

其中，圖4係本發明之第二實施例的絕熱容器1B之立體圖；圖5係圖4所示絕熱容器1B之構造之剖面圖；圖6係圖4所示絕熱容器1B之構造之分解剖面圖。又，以下的說明中，與該絕熱容器1A相同的部位省略其說明，且於圖式中標註相同符號。Among them, Fig. 4 is a three-dimensional view of the insulated container 1B of the second embodiment of the present invention; Fig. 5 is a cross-sectional view of the structure of the insulated container 1B shown in Fig. 4; and Fig. 6 is an exploded cross-sectional view of the structure of the insulated container 1B shown in Fig. 4. In the following description, the description of the same parts as the insulated container 1A is omitted, and the same symbols are marked in the drawings.

本實施例之絕熱容器1B，如圖4至圖6所示，外容器2具有為其中一構件的上側構件2c、以及為另一構件的下側構件2d，其中，上側構件2c構成外容器2的肩部及頭頸部，下側構件2d構成外容器2的底部及軀幹部。The insulated container 1B of this embodiment, as shown in Figures 4 to 6, has an outer container 2 having an upper side component 2c as one of the components and a lower side component 2d as the other component, wherein the upper side component 2c constitutes the shoulder and head and neck of the outer container 2, and the lower side component 2d constitutes the bottom and trunk of the outer container 2.

本實施例的絕熱容器1B在內容器3收容於上側構件2c之內側的狀態下，將上側構件2c及內容器3的開口端彼此對接，並將該對接部分藉由熔接接合。In the insulated container 1B of this embodiment, when the inner container 3 is accommodated inside the upper member 2c, the upper member 2c and the opening ends of the inner container 3 are butted against each other, and the butted portions are joined by welding.

又，本實施例之絕熱容器1B係在將下側構件2d的上端相對於與內容器3接合之上側構件2c嵌入至內側的狀態下，使上側構件2c與下側構件2d對接，藉由熔接將該等上側構件2a與下側構件2b之間接合，藉此構成外容器2。In addition, the insulated container 1B of this embodiment is configured such that the upper end of the lower side member 2d is embedded in the upper side member 2c joined to the inner container 3, the upper side member 2c is butted against the lower side member 2d, and the upper side member 2a and the lower side member 2b are joined by welding, thereby forming the outer container 2.

圖5雖圖示有上側構件2c與內容器3的接合部分(邊界)、以及上側構件2c與下側構件2d的接合部分(邊界)，但是在接合之後，藉由熔接來熔融該等接合部分，會於接合部分整圈形成焊珠。又，可透過於熔接後對該焊珠進行研磨及拋光加工以完成平滑表面。Although FIG5 shows the joint portion (border) between the upper member 2c and the inner container 3, and the joint portion (border) between the upper member 2c and the lower member 2d, after joining, the joint portions are melted by welding, and a weld bead is formed around the joint portion. In addition, the weld bead can be ground and polished after welding to complete a smooth surface.

本實施例之絕熱容器1B係在減壓狀態下，藉由熔接接合構成外容器2的上側構件2c與下側構件2d，在外容器2與內容器3之間形成真空絕熱層4。The insulating container 1B of this embodiment forms a vacuum insulating layer 4 between the outer container 2 and the inner container 3 by welding the upper member 2c and the lower member 2d constituting the outer container 2 under reduced pressure.

具體而言，在製造該絕熱容器1B時，係於減壓(真空吸引)之腔室內，使下側構件2d的上端成為相對於上側構件2c更嵌入至內側的狀態，在此狀態下，透過設置於腔室的窗部自外部對腔室內的絕熱容器1B照射雷射光。Specifically, when manufacturing the insulating container 1B, the upper end of the lower component 2d is made to be more embedded inward relative to the upper component 2c in a depressurized (vacuum suction) chamber. In this state, the insulating container 1B in the chamber is irradiated with laser light from the outside through a window provided in the chamber.

此時，一邊將絕熱容器1B繞中心軸旋轉，一邊沿著上側構件2c與下側構件2d的邊界照射雷射光，藉此，可精確地接合上側構件2a與下側構件2b。At this time, while rotating the insulating container 1B around the central axis, laser light is irradiated along the boundary between the upper member 2c and the lower member 2d, thereby accurately joining the upper member 2a and the lower member 2b.

相較於上述習知技術，本實施例的絕熱容器1B的製造方法，不需要加熱絕熱容器1B，在使用純鈦製作外容器2及內容器3時不需要退火，因此，可薄化外容器2及內容器3的厚度，另外，亦不需要加熱絕熱容器1B所需要的電力及時間。Compared to the above-mentioned known technology, the manufacturing method of the insulating container 1B of the present embodiment does not need to heat the insulating container 1B, and does not need annealing when using pure titanium to make the outer container 2 and the inner container 3. Therefore, the thickness of the outer container 2 and the inner container 3 can be thinned. In addition, the electricity and time required for heating the insulating container 1B are not required.

如上所述，本實施例的絕熱容器1B的製造方法可在不設置排氣用之槽縫的情況下在外容器2與內容器3之間形成真空絕熱層4。As described above, the manufacturing method of the insulated container 1B of this embodiment can form the vacuum insulation layer 4 between the outer container 2 and the inner container 3 without providing a groove for exhaust.

又，本實施例的絕熱容器1B的製造方法比起例如在下側構件2d之底面一部分設置排氣用槽縫的情況，可自上側構件2c與下側構件2d之間整圈排氣，因此，可縮短排氣所需要的時間，而可縮短平均製造時間。Furthermore, the manufacturing method of the insulated container 1B of this embodiment can exhaust air from the entire circle between the upper member 2c and the lower member 2d, compared to the case where, for example, a groove for exhaust is provided on a portion of the bottom surface of the lower member 2d. Therefore, the time required for exhaust can be shortened, and the average manufacturing time can be shortened.

然而，雖然本實施例的絕熱容器1B的製造方法係例示如上所述在減壓(真空吸引)的腔室內，將上側構件2c與下側構件2d之間整圈接合，但亦可將上側構件2c與下側構件2d之間留下一部分的未熔接部，並且將其等在大氣壓力中熔接接合，而在減壓狀態下，藉由熔接將該未熔接部藉由熔接密封，以在外容器2及內容器3之間形成真空絕熱層4。However, although the manufacturing method of the insulating container 1B of the present embodiment illustrates the method of joining the upper member 2c and the lower member 2d in a completely circle in a depressurized (vacuum suction) chamber as described above, it is also possible to leave a portion of the unwelded portion between the upper member 2c and the lower member 2d, and weld them together under atmospheric pressure, and then seal the unwelded portion by welding under a depressurized state to form a vacuum insulating layer 4 between the outer container 2 and the inner container 3.

具體而言，在密封該未熔接部時，係將密封前的絕熱容器1B收納於已減壓(真空吸引)之腔室內，並透過未熔接部使外容器2與內容器3之間排氣，在此狀態下，透過設置於腔室的窗部自外部對腔室內的絕熱容器1B照射雷射光。Specifically, when sealing the unwelded portion, the insulating container 1B before sealing is placed in a depressurized (vacuum suction) chamber, and air is exhausted from between the outer container 2 and the inner container 3 through the unwelded portion. In this state, the insulating container 1B in the chamber is irradiated with laser light from the outside through a window provided in the chamber.

此時可一邊將絕熱容器1A繞中心軸旋轉，一邊沿未熔接部照射雷射光，藉此可精確密封未熔接部。At this time, the unwelded portion can be accurately sealed by irradiating the unwelded portion with laser light while rotating the insulating container 1A around the central axis.

又，本實施例之絕熱容器1B的製造方法，亦可將上側構件2c與內容器3之間留下一部分未熔接部，並在減壓狀態下，將該未熔接部藉由熔接密封，以在外容器2及內容器3之間形成真空絕熱層4。Furthermore, the manufacturing method of the insulating container 1B of this embodiment can also leave a portion of the unwelded portion between the upper component 2c and the inner container 3, and seal the unwelded portion by welding under reduced pressure to form a vacuum insulating layer 4 between the outer container 2 and the inner container 3.

(第三實施例)(Third Embodiment)

接著，說明如圖7至圖9所示之本發明之第三實施例之絕熱容器1C及其製造方法。Next, the insulated container 1C and its manufacturing method according to the third embodiment of the present invention as shown in FIGS. 7 to 9 will be described.

其中，圖7係本發明之第三實施例的絕熱容器1C之立體圖；圖8係圖7所示絕熱容器1C之構造之剖面圖；圖9係圖7所示絕熱容器1C之構造之分解剖面圖。又，以下的說明中，與該絕熱容器1A相同的部位省略其說明，且於圖式中標註相同符號。Among them, Fig. 7 is a three-dimensional view of the insulated container 1C of the third embodiment of the present invention; Fig. 8 is a cross-sectional view of the structure of the insulated container 1C shown in Fig. 7; and Fig. 9 is an exploded cross-sectional view of the structure of the insulated container 1C shown in Fig. 7. In the following description, the description of the same parts as the insulated container 1A is omitted, and the same symbols are marked in the drawings.

本實施例之絕熱容器1C，如圖7至圖9所示，在將內容器3收納於外容器2之內側的狀態下，對齊外容器2及內容器3的開口端，並將對齊處以熔接接合。The insulated container 1C of this embodiment, as shown in FIG. 7 to FIG. 9, is in a state where the inner container 3 is accommodated inside the outer container 2, the opening ends of the outer container 2 and the inner container 3 are aligned, and the aligned portions are welded together.

圖5雖圖示有外容器2與內容器3的接合部分(邊界)，但是在接合之後，藉由熔接來熔融該等接合部分，會於接合部分整圈形成焊珠，又，可透過於熔接後對該焊珠進行研磨及拋光加工以完成平滑表面。Although FIG5 shows the joint portion (boundary) between the outer container 2 and the inner container 3, after the joint, the joint portions are melted by welding, and a weld bead is formed around the entire joint portion. Furthermore, the weld bead can be ground and polished after welding to complete a smooth surface.

本實施例之絕熱容器1C係在減壓狀態下，藉由熔接接合構成外容器2與內容器3，以在外容器2與內容器3之間形成真空絕熱層4。The insulating container 1C of this embodiment is formed by welding an outer container 2 and an inner container 3 under reduced pressure to form a vacuum insulating layer 4 between the outer container 2 and the inner container 3.

具體而言，在製造該絕熱容器1C時，係於減壓(真空吸引)之腔室內，使外容器2與內容器3的開口端周邊成為對齊的狀態，在此狀態下，透過設置於腔室的窗部自外部對腔室內的絕熱容器1C照射雷射光。Specifically, when manufacturing the insulating container 1C, the opening ends of the outer container 2 and the inner container 3 are aligned in a depressurized (vacuum suction) chamber. In this state, the insulating container 1C in the chamber is irradiated with laser light from the outside through a window provided in the chamber.

此時，一邊將絕熱容器1C繞中心軸旋轉，一邊沿著外容器2與內容器3的邊界照射雷射光，藉此，可精確地接合外容器2與內容器3。At this time, while the insulating container 1C is rotated around the central axis, laser light is irradiated along the boundary between the outer container 2 and the inner container 3, thereby accurately joining the outer container 2 and the inner container 3.

相較於上述習知技術，本實施例的絕熱容器1C的製造方法，不需要加熱絕熱容器1C，在使用純鈦製作外容器2及內容器3時不需要退火，因此，可薄化外容器2及內容器3的厚度，另外，亦不需要加熱絕熱容器1C所需要的電力及時間。Compared to the above-mentioned known technology, the manufacturing method of the insulating container 1C of the present embodiment does not need to heat the insulating container 1C, and does not require annealing when using pure titanium to make the outer container 2 and the inner container 3. Therefore, the thickness of the outer container 2 and the inner container 3 can be thinned. In addition, the electricity and time required for heating the insulating container 1C are not required.

如上所述，本實施例的絕熱容器1C的製造方法可在不設置排氣用之槽縫的情況下，在外容器2與內容器3之間形成真空絕熱層4。As described above, the manufacturing method of the insulating container 1C of this embodiment can form the vacuum insulating layer 4 between the outer container 2 and the inner container 3 without providing a groove for exhaust.

又，本實施例的絕熱容器1C的製造方法比起例如在外容器2之底面一部分設置排氣用槽縫的情況，可自外容器2與內容器3之間整圈排氣，因此，可縮短排氣所需要的時間，而可縮短平均製造時間。Furthermore, the manufacturing method of the insulated container 1C of this embodiment can exhaust air from the entire circle between the outer container 2 and the inner container 3, compared to the case where, for example, a groove for exhaust is provided on a portion of the bottom surface of the outer container 2. Therefore, the time required for exhaust can be shortened, and the average manufacturing time can be shortened.

然而，雖然本實施例的絕熱容器1C的製造方法係例示如上所述在減壓(真空吸引)的腔室內，將外容器2與內容器3之間整圈接合，但亦可將外容器2與內容器3之間留下一部分的未熔接部，並且將其等在大氣壓力中熔接接合，而在減壓狀態下，將該未熔接部藉由熔接密封，以在外容器2及內容器3之間形成真空絕熱層4。However, although the manufacturing method of the insulating container 1C of the present embodiment illustrates the example of joining the outer container 2 and the inner container 3 in a completely circle in a depressurized (vacuum suction) chamber as described above, it is also possible to leave a portion of the outer container 2 and the inner container 3 unwelded and weld them together under atmospheric pressure, and then seal the unwelded portion by welding under a depressurized state to form a vacuum insulating layer 4 between the outer container 2 and the inner container 3.

具體而言，在密封該未熔接部時，係將密封前的絕熱容器1C收納於已減壓(真空吸引)之腔室內，並透過未熔接部使外容器2與內容器3之間排氣，在此狀態下，透過設置於腔室的窗部自外部對腔室內的絕熱容器1C照射雷射光。Specifically, when sealing the unwelded portion, the insulating container 1C before sealing is placed in a depressurized (vacuum suction) chamber, and air is exhausted from between the outer container 2 and the inner container 3 through the unwelded portion. In this state, the insulating container 1C in the chamber is irradiated with laser light from the outside through a window provided in the chamber.

此時可一邊將絕熱容器1C繞中心軸旋轉，一邊沿未熔接部照射雷射光，藉此可精確密封未熔接部。At this time, the unwelded portion can be accurately sealed by rotating the insulating container 1C around the central axis while irradiating the unwelded portion with laser light.

又，本實施例之絕熱容器1C的製造方法，亦可將外容器2與內容器3之間留下一部分的未熔接部，並在減壓狀態下，將該未熔接部藉由熔接密封，藉此在外容器2及內容器3之間形成真空絕熱層4。Furthermore, the manufacturing method of the insulating container 1C of this embodiment can also leave a portion of the unwelded portion between the outer container 2 and the inner container 3, and seal the unwelded portion by welding under a reduced pressure state, thereby forming a vacuum insulating layer 4 between the outer container 2 and the inner container 3.

然而，本發明不限於上述實施例，在不脫離本發明精神範圍內可加諸各種變化，例如，上述實施例中雖然例示了將本發明之絕熱容器1A、1B、1C應用在帶蓋容器之容器本體的情況，但也可以將本發明應用於廣泛的隔熱容器，如具有保溫和保冷功能的水瓶和杯子等飲料容器，具有保溫功能的食品容器和炊具等。However, the present invention is not limited to the above-mentioned embodiments, and various changes can be made without departing from the spirit and scope of the present invention. For example, although the above-mentioned embodiments illustrate the case where the insulated containers 1A, 1B, and 1C of the present invention are applied to the container body of a container with a lid, the present invention can also be applied to a wide range of insulated containers, such as beverage containers such as water bottles and cups with heat preservation and cold preservation functions, food containers and cooking utensils with heat preservation functions, etc.

按，以上所述，僅係本發明之較佳實施例，惟，本發明所主張之權利範圍，並不侷限於此，按凡熟悉該項技藝人士，依據本發明所揭露之技術內容，可輕易思及之等效變化，均應屬不脫離本發明之保護範疇。The above is only a preferred embodiment of the present invention. However, the scope of rights claimed by the present invention is not limited thereto. Any equivalent changes that can be easily conceived by those familiar with the art based on the technical content disclosed in the present invention should not deviate from the protection scope of the present invention.
