Abstract
Description
本發明是關於一種密封墊結構及密封蓋結構,特別是關於一種用於密封容器的密封墊結構及密封蓋結構。 The invention relates to a sealing pad structure and a sealing cover structure, in particular to a sealing pad structure and a sealing cover structure for a sealed container.
一般裝有不同液體(例如:牛乳、機油、酒精、化學液體、洗腎液及醫療藥水等)之瓶子(或容器),為了達到良好的密封效果,以往在瓶子的開口處會使用鋁箔墊片或鋁箔封口膜等進行密封。使用該些鋁箔製的密封方式,雖然有很好的氣密性與防漏性,然而因鋁箔墊片及鋁箔封口膜是透過加熱及/或黏膠的方式來達到封口的效果,因此對於一般消費者,尤其是小孩及老弱者,常感不易開啟。而且鋁箔墊片及鋁箔封口膜一旦被撕下,若非只能丟棄,即為難以回復密封,故開啟的瓶子立即失去密封效果,因而不僅縮短瓶內液體的保存期限,並且有易於溢漏出來之缺點。 Generally, bottles (or containers) containing different liquids (such as: milk, engine oil, alcohol, chemical liquids, kidney dialysis solution, medical potions, etc.), in order to achieve a good sealing effect, aluminum foil gaskets were used at the opening of the bottle in the past Or aluminum foil parafilm, etc. for sealing. Although these sealing methods made of aluminum foil have good airtightness and leakproofness, because the aluminum foil gasket and aluminum foil sealing film achieve the sealing effect through heating and/or glue, so for general Consumers, especially children and the elderly, often find it difficult to open. Moreover, once the aluminum foil gasket and aluminum foil sealing film are torn off, if they can only be discarded, it is difficult to restore the seal, so the opened bottle immediately loses the sealing effect, thus not only shortening the shelf life of the liquid in the bottle, but also prone to spillage shortcoming.
此外,市面上亦有出現用於瓶口與瓶蓋之間的密封墊結構,然而,該些密封墊雖然設置於瓶口與瓶蓋之間,卻因公差與設計等問題,皆無法有效地將蓋體與瓶子間的空隙填滿,亦或是無法將密封墊完整地覆蓋於瓶口或瓶口周緣外側,故也都不具備良好的密封與防漏的效果。 In addition, there are also gasket structures used between the bottle mouth and the bottle cap on the market. However, although these gaskets are arranged between the bottle mouth and the bottle cap, they cannot be effectively used due to tolerance and design issues. The gap between the cap and the bottle is filled, or the sealing gasket cannot be completely covered on the outside of the bottle mouth or the periphery of the bottle mouth, so it does not have a good sealing and leak-proof effect.
綜上,如何提供一種密封效果良好,又可反覆使用,甚至可重覆使用於不同的瓶子與瓶蓋之間的密封墊結構,乃成為本技術領域中亟待改善的 問題與需求。 To sum up, how to provide a gasket structure that has a good sealing effect and can be used repeatedly, even between different bottles and bottle caps, has become an urgent need for improvement in this technical field. problems and needs.

於本發明之第一較佳實施例中,一種用於密封容器的密封墊結構10A被提出,各元件的技術內容依序說明如下。
In the first preferred embodiment of the present invention, a sealing
請參第1A圖至第1C圖之實施例,係為一種用於密封容器的密封墊結構10A。密封墊結構10A基本上包括本體100,本體100係為一圓形狀,並包含頂板110,而沿著頂板110之一法線方向,頂板100之同一表面周緣上設有外壁111及內壁112,外壁111及內壁112之間形成環狀溝槽113,換言之,外壁111及內壁112係呈連續環狀。
Please refer to the embodiment of Fig. 1A to Fig. 1C, which is a
接著請參閱第1B圖,內壁112於該法線方向之長度係大於外壁111之長度。於其他不同實施例中,內壁112的長度亦可低於或等於外壁111(圖未示)。請參第1C圖及第3B圖,該環狀溝槽113可為凹面、平面或凸面,而環狀溝槽113可因應瓶子10C的瓶口300之設計,而選擇凹面、平面或凸面之設計(圖未示),以達到最佳的密合效果。另外,外壁111包含外壁外表面114及外壁內表面115,而內壁112包含內壁外表面116。其中,密封墊結構10A的材質可為聚乙烯(PE,Polyethylene)、聚丁烯(PB,Polybutene)或低密度聚乙烯(LDPE,Low density Polyethylene)等的高分子聚合材質所構成的塑料材質。
Then please refer to FIG. 1B , the length of the
於第2A圖至第2C圖所示之實施例中,其為本發明的第二較佳實施例,係為一種用於密封容器之密封蓋結構(下稱密封蓋結構)10B,包含蓋子本體200及上述第一實施例的密封墊結構10A,包含內底面210、外表面220及連續圍壁230。其中,密封墊結構10A設置於連續圍壁230之內側232,且貼靠於內底面210。
In the embodiment shown in Fig. 2A to Fig. 2C, it is the second preferred embodiment of the present invention, which is a sealing cap structure (hereinafter referred to as the sealing cap structure) 10B for sealing containers, including the
請復參第2B圖至第2C圖,密封墊結構10A與密封蓋結構10B係為二個獨立的元件,因此密封墊結構10A可反覆拆卸或安裝至密封蓋結構10B中,而當密封墊結構10A裝入至密封蓋結構10B的蓋子本體200時,可將密封墊結構10A押緊至貼靠於內底面210,並且密封墊結構10A的外壁111亦會貼合蓋子本體200之連續圍壁230之內側232,以達到固定貼合的效果。另外,蓋子本體200的連續圍壁230之外側231上可設有複數個突起部233(其功效與實施例容後敘述),其中,複數個突起部233係沿內底面210及外表面220之法線方向延伸。另,蓋子本體200之材質可為聚乙烯(PE,Polyethylene)、聚丁烯(PB,Polybutene)
或高密度聚乙烯(HDPE,High density Polyethylene)等的高分子聚合材質所構成的塑料材質。
Please refer to Fig. 2B to Fig. 2C again, the
如第1D圖所示,於某些實施例的情況中,密封墊結構10A’為高分子聚合材質所構成的塑料材質,因此具有一定的彈性。為了增加密封墊結構10A’與密封蓋結構10B的穩固效果,密封墊結構10A’的外壁111之外緣上設有至少一扣合部117。藉此,當密封墊結構10A’裝入至密封蓋結構10B的蓋子本體200內時(圖未示),扣合部117可透過塑料材質的彈性壓力,使密封墊結構10A’的外壁111因擠壓,而與蓋子本體200的內側232的產生反作用力,進而提升穩固的效果。
As shown in FIG. 1D , in some embodiments, the
藉由扣合部117的設計,因不需將密封墊結構10A’之外壁111尺寸做到完全與蓋子本體200的內側232完全一致,故密封墊結構10A’於製造時,在射出成型階段時亦可節省一定的材料成本,並更易於大量製造。而除了扣合部117以外,因外壁111並非完全地貼合內側232,故使用者可輕易地用手或工具將密封墊結構10A’從蓋子本體200的內底面210上拆除。需另外說明的是,密封墊結構10A亦為具有彈性的塑料材質,因此與密封墊結構10A’皆可從蓋子本體200內輕易地拆卸,而拆卸後的密封墊結構10A、10A’亦可用清水將灰塵、油垢、細菌等髒汙清洗乾淨,而清洗過後的密封墊結構10A、10A’可再度裝回蓋子本體200繼續使用,維持原有的密封效果外,亦可保持該元件上的潔淨與衛生。此外,若密封墊結構10A損壞,亦可直接拆卸下來單獨進行更換,而不需將整個密封蓋結構10B更換。
Due to the design of the
請參閱第3A圖至第3B圖,於某些實施例中,密封蓋結構10B應用於容器之實施態樣,該容器可以是瓶子、桶子、杯子等任何可裝液體之容器(以下以瓶子10C為例)。另外,外側231上的突起部233可讓使用者手指握住蓋子本
體200時,便於增加手指與蓋子本體200之間的摩擦力,進而使蓋子本體200容易旋轉。此外,蓋子本體200的外側231之設計不在此限,外側231亦可設有複數的凹槽或其他可增加蓋子本體200之外側231摩擦力之設計(圖未示)。
Please refer to Fig. 3A to Fig. 3B, in some embodiments, sealing
請復參第3B圖,當密封蓋結構10B(密封墊結構10A設置於蓋子本體200中)裝設於瓶子10C時,密封墊結構10A的外壁111與內壁112將會夾置於瓶口300上,進而使密封墊結構10A會完整地密封於瓶口300之上。具體而言,密封蓋結構10B旋轉裝設至瓶子10C時,會產生一擠壓應力及向下壓力,此時,該擠壓應力會藉由蓋子本體200對外壁外表面114施加壓力,進而使外壁內表面115更加地貼合至瓶口外表面310,而該向下壓力會使外壁111與內壁112之間的環狀溝槽更可緊密貼合至瓶口300上,該向下壓力亦會使內壁外表面116可完整地貼合至瓶口內表面320。藉此,密封墊結構10A可更加地密封住瓶口300的任一縫隙。
Please refer to FIG. 3B again. When the sealing
另外,請參閱第4A圖至第4B圖,於某些實施例中密封墊結構10A”包含本體100,本體100包含底板120,並沿著底板120之一法線方向,於底板120之上表面121之周緣設有內壁112,內壁112的上端之外緣上設有外壁111,內壁112及外壁111之間形成環狀溝槽113。
In addition, please refer to FIG. 4A to FIG. 4B. In some embodiments, the
具體而言,密封墊10A”的外壁111係從內壁112向外延伸出去,且密封墊結構10A”具有外壁111及內壁112,故密封墊結構10A”同樣地具有環狀溝槽113,藉此,當密封墊結構10A”設置於蓋子本體200中(圖未示),同樣地可藉由密封蓋結構10B旋轉時所產生的該擠壓應力及向下壓力,使密封墊結構10A”的外壁111、內壁112及環狀溝槽113完整地密封於瓶口300。另外,密封墊結構10A”也可以輕易地從蓋子本體200中拆除,且密封墊結構10A”亦可具有扣合部117來增加與蓋子本體200之穩固性。此外,因密封墊結構10A”與蓋子本體
200的各實施方式及技術手段與其他實施例相當,且密封墊結構10A”之材質亦跟密封墊材質10A相當,故關於密封墊結構10A”與蓋子本體200使用於瓶子10C的詳細說明予以省略。
Specifically, the
綜上所述,本發明的密封墊結構10A的外壁111之外壁內表面115可完整地貼合瓶口外表面310,完成第一階段的防漏措施;環狀溝槽113可完整地貼合至瓶口300,完成第二階段的防漏措施;內壁112的內壁外表面116可完整地貼合至瓶子10C的瓶口內表面320完成第三階段的防漏措施。值得一提的是,內壁112於該法線方向之長度係大於外壁111之長度,可讓內壁112的部分更加地插入瓶子10C中,藉此提升防漏效果。換言之,因密封墊結構10A具有外壁111及內壁112及環狀溝槽113之設計,故密封蓋結構10B裝至瓶子10C時,密封墊結構10A可以做到完全地防漏效果。除此之外,因本發明的密封墊結構10A為具有彈性的塑料材質,因此可隨時地從密封蓋結構10B上拆卸下來清洗及更換。
In summary, the
上述實施例只是舉例來說明本發明,而非為了限制本發明的保護範圍。任何針對上述實施例進行修飾、改變、調整、整合而產生的其他實施例,只要是本發明所屬技術領域中具有通常知識者不難思及的,都已涵蓋在本發明的保護範圍內。本發明的保護範圍以申請專利範圍為準。 The above-mentioned embodiments are just examples to illustrate the present invention, and are not intended to limit the protection scope of the present invention.
