Description
本發明與玻璃瓶的密封蓋有關;本發明密封蓋是塑料外蓋和金屬內蓋的複合體,在塑料外蓋上具有拉環。 The present invention is related to the sealing cap of the glass bottle; the sealing cap of the present invention is a composite of a plastic outer cap and a metal inner cap, and a pull ring is provided on the plastic outer cap.
圖一及圖二描述習知玻璃瓶的密封蓋2,該密封蓋2為鋁蓋,經封蓋機封壓於玻璃瓶瓶口1。在密封蓋2包含一蓋本體3和一捲覆邊4,蓋本體3覆蓋於瓶口1,捲覆邊4密合捲覆固定於瓶口邊側。為達密封效果,蓋本體3內圓周處還包括一彈性密封環5,該彈性密封環5密封於瓶口的頂緣及其外角。兩道預切割線6呈預定間隔的設於該捲覆邊4並分別向蓋本體3的外周緣環狀延伸。在兩道預切割線6之間的捲覆邊更一體連接一拉環7。在密封蓋2與瓶口密封的狀態下,該拉環7垂直的靠合在玻璃瓶外部。
Figures 1 and 2 depict the sealing
圖二揭露開啟密封蓋2的方式。向上拉起拉環7,使捲覆邊4及蓋本體3沿著兩道預切割線6分離,即可從瓶口上取下密封蓋2。
Figure 2 reveals the way to open the sealing
圖一、圖二習知的密封蓋待改善的問題如下: The problems to be improved for the conventional sealing cover in Figure 1 and Figure 2 are as follows:
一是開啟後的密封蓋沿著預切割線形成了鋒利邊,極容易傷及使用者。二是蓋本體密封於瓶口時沒有提供真空辨識,消費者無法經由目視蓋本體而判斷玻璃瓶內是否為真空保鮮狀態。三是開蓋費力,使用者必需用較大的力量才能使拉環與蓋本體沿著預切割線撕開。四是機械封蓋時,往下延伸的拉環容易影響封蓋程序。五是包裝封膜時貼靠在玻璃瓶外部的 拉環使包裝封膜不容易施配,且包裝封膜亦因拉環而極不平整。 One is that the opened sealing cover forms a sharp edge along the pre-cut line, which can easily injure the user. Second, when the lid body is sealed on the bottle mouth, no vacuum identification is provided, and consumers cannot judge whether the glass bottle is in a vacuum preservation state by visually inspecting the lid body. The third is that it is laborious to open the lid, and the user must use a relatively large force to tear the pull ring and the lid body along the pre-cut line. Fourth, when mechanically capping, the downwardly extending pull ring easily affects the capping procedure. Fifth, it is attached to the outside of the glass bottle when packaging and sealing the film The pull ring makes it difficult to dispense the packaging and sealing film, and the packaging and sealing film is also extremely uneven due to the pull ring.
本發明提出一種具拉環的複合密封蓋,具體技術是:一塑料外蓋,包括定義一圓形孔的一內環緣、連接該內環緣的一環肩,以及連接於該環肩的一環側;一拉環位於該圓形孔中,該拉環通過一不斷裂連接部連接著該內環緣;該環側的內壁面凸設有至少兩個第一定位部和至少一第二定位部;一金屬內蓋,為衝壓成型結構,包括一頂部、一側部以及介於該頂部和側部之間的一肩部;該頂部的中心區域成型一可上下浮動的真空識別鈕;該金屬內蓋的內側面從該頂部的外圓周延續至該肩部及該側部上段結合一環狀的密封襯墊,該密封襯墊為TPE(Thermoplastic Elastomer,熱可塑性彈性體)材質製成;該金屬內蓋順形結合於該塑料外蓋的內部,該真空識別鈕顯露於該塑料外蓋的圓形孔的中心位置,該第一、第二定位部位於該金屬內蓋的內捲壓邊之下;該複合密封蓋結合於玻璃瓶的該瓶口,該密封襯墊及該金屬內蓋密合該瓶口,該密封墊圈的該止漏環緊密合該瓶口的內壁,該第一定位部和該第二定位部卡止於該階差。 The present invention provides a composite sealing cover with pull ring. The specific technology is: a plastic outer cover, including an inner ring edge defining a circular hole, a ring shoulder connected to the inner ring edge, and a ring connected to the ring shoulder Side; a pull ring is located in the circular hole, the pull ring is connected to the inner ring edge by a non-breaking connecting portion; the inner wall surface of the ring side is convexly provided with at least two first positioning portions and at least one second positioning A metal inner cover, which is a stamped and formed structure, includes a top, a side, and a shoulder between the top and the side; the central area of the top is formed with a vacuum identification button that can float up and down; the The inner side of the metal inner cover continues from the outer circumference of the top to the shoulder and the upper section of the side combined with an annular sealing gasket made of TPE (Thermoplastic Elastomer) material; The metal inner cover is conformally combined with the inside of the plastic outer cover, the vacuum identification button is exposed at the center of the circular hole of the plastic outer cover, and the first and second positioning parts are located in the inner rolling pressure of the metal inner cover Under the side; the composite sealing cap is combined with the mouth of the glass bottle, the sealing gasket and the metal inner cap are tightly sealed with the mouth, the leak-proof ring of the sealing gasket is tightly sealed with the inner wall of the mouth, the The first positioning portion and the second positioning portion are locked at the level difference.
本發明具拉環的複合密封蓋的優點在於: The advantages of the compound sealing cover with pull ring of the present invention are:
完全沒有封利邊,確保使用安全。 There is no sealing edge at all to ensure safe use.
拉環設於該塑料外蓋的頂部,整個複合密封蓋具有平整的外輪廓,拉環對機械封蓋動作不會造成影響,包裝封膜容易施配且在瓶蓋上趨於平整。 The pull ring is arranged on the top of the plastic outer cover. The entire composite sealing cap has a flat outer contour. The pull ring will not affect the mechanical sealing action. The packaging sealing film is easy to dispense and tends to be flat on the bottle cap.
該第一定位部和該第二定位部具有以下功能,一是將該金屬內蓋保持於該塑料外蓋中,二是將複合密封蓋定位於該玻璃瓶的瓶口,三是開 啟瓶蓋時將該金屬內蓋撥離該玻璃瓶的瓶口。 The first positioning portion and the second positioning portion have the following functions: one is to keep the metal inner cap in the plastic outer cap, the other is to position the composite sealing cap on the mouth of the glass bottle, and the third is to open When opening the bottle cap, pull the metal inner cap away from the mouth of the glass bottle.
該拉環、該第一定位部、該第二定位部之協同作用使開啟複合密封蓋時產生類似槓桿原理的作用,與先前技術相較,本發明使用該拉環拉開該複合密封蓋時較為省力。 The synergistic effect of the pull ring, the first positioning portion, and the second positioning portion produces a lever-like effect when the composite sealing cover is opened. Compared with the prior art, the present invention uses the pull ring to open the composite sealing cover. Less effort.
該金屬內蓋的該密封襯墊為TPE(Thermoplastic Elastomer,熱可塑性彈性體),符合環保和食品安全規範。 The sealing gasket of the metal inner cover is TPE (Thermoplastic Elastomer), which complies with environmental protection and food safety regulations.
取下的複合密封蓋因金屬內蓋與塑料外蓋沒有膠合固定之關係,因此可使金屬內蓋往通過該第一定位部和第二定位部的方向脫離該塑料外蓋,兩者分開做資源回收。 The removed composite sealing cover has no glued and fixed relationship between the metal inner cover and the plastic outer cover, so the metal inner cover can be separated from the plastic outer cover in the direction of passing through the first positioning part and the second positioning part. The two are made separately Recycle.
該金屬內蓋的內壓捲邊開放端被該密封襯墊的側緣包覆,避免該處氧化而影響食品安全。 The open end of the inner pressure crimping edge of the metal inner cover is covered by the side edge of the sealing gasket, so as to avoid oxidation in this place and affecting food safety.
消費者可經由目視該真空識別鈕而判斷玻璃瓶內是否為真空保鮮狀態。 Consumers can judge whether the glass bottle is in a vacuum preservation state by visually viewing the vacuum identification button.

如圖三和圖四,本發明具拉環的複合密封蓋通過封蓋機結合於一玻璃瓶的瓶口51。從外觀上,本發明具拉環的複合密封蓋為塑料外蓋10和金屬內蓋20的複合體,塑料外蓋10是環狀體,其上有一拉環30。玻璃瓶和瓶口51形狀是習知的,在瓶口51與玻璃瓶外壁形成一階差52。
As shown in Figures 3 and 4, the composite sealing cap with pull ring of the present invention is combined with the
如圖五至圖八,該塑料外蓋10包括定義一圓形孔11的一內環緣12、連接該內環緣12的一環肩14,以及連接於該環肩14且呈垂直向的一環側15。
As shown in Figures 5 to 8, the plastic
該拉環30成型於該內環緣12所定義的圓形孔11中。該內環緣12包含斜面朝上的斜切面13,該拉環30位於該斜切面13上,使該拉環30不凸出於該塑料外蓋10。該拉環30通過一不斷裂連接部31連接著該內環緣12。該環肩14設一指凹陷部16,供使用者的手指通過該指凹陷部16接觸該拉環30。通過該塑料外蓋10直徑的一虛擬直徑線L1會通過該指凹陷部16和該不斷裂連接部31的中心點。
The
該環側15的內壁面,凸設有至少兩個第一定位部41和至少一第二定位部42。通過一虛擬直徑線L1來定義該第一定位部41和該第二定位部42
的位置。該虛擬直徑線L1通過該塑料外蓋10的直徑和該不斷裂連接部31中心點。該第二定位部42的中心點位於該虛擬直徑線L1的一端,該二第一定位部41分別位於該虛擬直徑線L1的另一端兩側鏡射位置。
The inner wall surface of the
該第一定位部41包含一第一端411和一第二端412,該第一端411與該虛擬直徑線L1所構成的圓心角θ1為40度至50度,較佳為45度;該第二端412與該虛擬直徑線L1所構成的圓心角θ2為60-70度,較佳為65度。該第二定位部42亦包含一第一端421和一第二端422,該第一端421與第二端422所構成的圓心角θ3為110-130度,較佳為120度。
The
該金屬內蓋20為衝壓成型結構,包括一頂部21、一側部22以及介於該頂部21和該側部22之間的一肩部23。該頂部21的中心區域成型一可上下浮動的真空識別鈕24。該金屬內蓋20的內側面從該頂部21的外圓周延續至該肩部23及該側部22上段結合一環狀的密封襯墊25,該側部22的下段向內捲壓形成一內壓捲邊26,該內壓捲邊26的開放端被該密封襯墊25的側緣包覆住。該密封襯墊25的內緣向下成型凸出一止漏環252。該密封襯墊25為TPE(Thermoplastic Elastomer,熱可塑性彈性體)材質製成。
The metal
該金屬內蓋20順形結合於該塑料外蓋10的內部,該真空識別鈕24顯露於該塑料外蓋10的圓形孔11的中心位置,該第一定位部41和第二定位部42位於該金屬內蓋20的內壓捲邊26之下,擋住該金屬內蓋20,使其不脫離該塑料外蓋10。
The metal
如圖九,該具拉環的複合密封蓋通過封蓋機結合於玻璃瓶的瓶口51,該密封襯墊25密合該瓶口51的頂面和外角,該密封襯墊25的止漏環252緊密合該瓶口51的內壁,該第一定位部41和該第二定位部42卡止於該玻璃
瓶的階差52。玻璃瓶因內容物從熱溫至冷卻而造成瓶內真空,強大的內部吸力使該金屬內蓋20以密封環緊密無縫密封住瓶口51,並且該真空識別鈕24往下伏。
As shown in Figure 9, the composite sealing cap with pull ring is combined with the
如圖十至十二揭露開啟該具拉環的複合密封蓋的方式。首先,使用者以手指的指間通過該指凹陷部16將該拉環30往上挑起,以便於該拉環30能套住一個手指的指尖。接著,施予該拉環30一個越過該指凹陷部16的拉力,該拉環30通過該不斷裂連接部31將拉力施予該塑料外蓋10,該塑料外蓋10以第二定位部42和該階差52的卡位關係做為該具拉環的複合密封蓋的支點,密封蓋依據槓桿原理使受拉力的塑料外蓋10的局部往上移動脫離該瓶口51,該第一定位部41脫離該階差52,同時該第一定位部41將該金屬內蓋20往上撥,使其脫離該瓶口51,解除瓶內的真空狀態。接著,繼續拉該拉環30,使第二定位部42也脫離該階差52,整個具拉環的複合密封蓋即可脫離該瓶口51。而藉著該第一定位部41和第二定位部42的擋止,該金屬內蓋20被保持於該塑料外蓋10中。
