Description
本發明，是樹脂容器的蓋構造，詳細的話，有關於樹脂容器的蓋構造，具有：在外周面具有公螺紋部的口部、及在內周面具有複數突起部在圓周方向間斷地連結成為母螺紋部的帽，前述公螺紋部，是在至少圓周方向的一部分，具有從前述口部的先端至末端之間的螺峯數量是一條的一螺紋部分，將前述帽的前述母螺紋部螺合在前述口部的前述公螺紋部使前述口部藉由前述帽捲緊而密閉。 The present invention relates to a lid structure of a resin container, and more particularly to a lid structure of a resin container, comprising: a mouth portion having a male screw portion on an outer peripheral surface; and a plurality of protrusion portions on the inner peripheral surface intermittently connected in the circumferential direction a cap of the female screw portion, wherein the male screw portion has a threaded portion having a number of spiral peaks from a tip end to a tip end of the mouth portion in at least a part of the circumferential direction, and the female thread portion of the cap is screwed The male screw portion that is fitted to the mouth portion seals the mouth portion by the cap.
例如，將碳酸飲料充填至樹脂容器的場合，碳酸飲料是由氣氛溫度高的場所被保管的話，內容物會熱膨脹，進一步，碳酸會從液中脫出，伴隨此使樹脂容器內的內壓提高。內壓提高的話，帽的頂面雖成為被推舉的狀態，但是設在口部的公螺紋部及帽的母螺紋部因為是位於螺合狀態，所以公螺紋部可防止其下側的母螺紋部的推舉，由此，帽的頂面的推舉被抑制。此結果，樹脂容器內 是被保持在密閉狀態，碳酸的脫出被抑制。 For example, when a carbonated beverage is filled in a resin container, when the carbonated beverage is stored in a place where the atmosphere temperature is high, the content is thermally expanded, and further, carbonic acid is released from the liquid, thereby increasing the internal pressure in the resin container. . When the internal pressure is increased, the top surface of the cap is in a state of being pushed. However, since the male screw portion of the mouth portion and the female screw portion of the cap are in a screwed state, the male thread portion can prevent the female thread on the lower side thereof. As a result of the recommendation, the push of the top surface of the cap is suppressed. This result is inside the resin container It is kept in a sealed state, and the escape of carbonic acid is suppressed.
對於此，發明人發現，公螺紋部，是在圓周方向的一部分，具有從口部的先端至末端之間的螺峯數成為一條的一螺紋部分的情況，在該一螺紋部分防止母螺紋部的推舉的力會變弱。此情況，樹脂容器內的內壓提高時，樹脂容器內的密閉狀態被妨害，碳酸具有脫出的可能。為了解決此，考慮變更口部設計使一螺紋部分不會產生，但是此也會伴隨帽的設計變更。且，藉由增加螺峯使口部高度增加的成為特殊規格口部規格的話，也有無法泛用等的問題。 In view of the above, the inventors have found that the male thread portion is a portion in the circumferential direction, and has a threaded portion in which the number of the peaks between the tip end and the end of the mouth portion becomes one, and the female thread portion is prevented at the one thread portion. The power of the referral will weaken. In this case, when the internal pressure in the resin container is increased, the sealed state in the resin container is impaired, and carbonic acid may be released. In order to solve this, it is considered to change the mouth design so that a threaded portion does not occur, but this also is accompanied by a design change of the cap. In addition, when the height of the mouth is increased by the increase of the peak, the size of the mouth is a special specification, and there is a problem that it cannot be used in general.
在此，本發明的目的，是提供一種樹脂容器的蓋構造，只有變更帽的構成就可將樹脂容器內的密閉狀態最佳地保持。 Accordingly, an object of the present invention is to provide a lid structure for a resin container which can optimally hold a sealed state in a resin container only by changing the configuration of the cap.
本發明的樹脂容器的蓋構造，是具有：在外周面具有公螺紋部的口部、及在內周面具有複數突起部在圓周方向間斷地連結成為母螺紋部的帽，前述公螺紋部，是在至少圓周方向的一部分，具有從前述口部的先端至末端之間的螺峯數量是一條的一螺紋部分，將前述帽的前述母螺紋部螺合在前述口部的前述公螺紋部使前述口部藉由 前述帽捲緊而密閉，其特徵為：設有延設突起部，其是被載置在前述公螺紋部中的前述一螺紋部分的下側的前述母螺紋部中的前述突起部，圓周方向的長度比其他的前述突起部的圓周方向的長度長。 The lid structure of the resin container according to the present invention includes a mouth portion having a male screw portion on the outer peripheral surface, and a cap having a plurality of projection portions on the inner peripheral surface that are intermittently connected to the female screw portion in the circumferential direction, and the male screw portion is a portion of at least one of the circumferential directions, having a threaded portion having a number of spiral peaks from a tip end to a tip end of the mouth portion, and screwing the female thread portion of the cap to the male thread portion of the mouth portion The aforementioned mouth The cap is wound and tightly sealed, and is characterized in that: the extending protrusion is provided on the protruding portion of the female screw portion on the lower side of the one threaded portion of the male screw portion, and the circumferential direction The length is longer than the length of the other protrusions in the circumferential direction.
通常，為了輕量化的要求、及將在帽裝設時溢出而殘留於母螺紋部的殘留物去除、及為了將內部的壓力效率佳地放出，在帽的母螺紋部中形成間隙，使複數突起部在圓周方向間斷地連結。且，發明人發現，對於上述課題，不需要變更口部的公螺紋部的形狀，在複數突起部間斷地連結帽的母螺紋部的形狀中，對於與一螺紋部分卡合(即被配置於一螺紋部分的下側)的突起部，藉由加長其長度就可以將防止母螺紋部的推舉的力補強。即，母螺紋部的推舉，雖是伴隨突起部的變形，但是藉由加長突起部的長度，就可以抑制突起部的變形，其結果，母螺紋部的推舉被抑制。 Usually, in order to reduce the weight and the residue remaining in the female screw portion when the cap is installed, and to release the internal pressure efficiently, a gap is formed in the female screw portion of the cap to make a plurality of The projections are intermittently connected in the circumferential direction. Further, the inventors have found that, in the above-described problem, it is not necessary to change the shape of the male screw portion of the mouth portion, and the female screw portion of the cap is intermittently coupled to the plurality of projection portions, and is engaged with a threaded portion (that is, disposed on the threaded portion). The protrusion of the lower side of the threaded portion can be reinforced by the lengthening of the length to prevent the pushing of the female thread portion. In other words, the pressing of the female thread portion is accompanied by deformation of the protruding portion. However, by lengthening the length of the protruding portion, deformation of the protruding portion can be suppressed, and as a result, the pushing of the female thread portion is suppressed.
且在上述構成中，因為被配置於一螺紋部分的下側的突起部，是作成圓周方向的長度比其他的突起部的圓周方向的長度長的延設突起部，所以可以抑制母螺紋部的推舉，可以抑制帽的頂面的推舉。因此，只變更帽的構成就可將樹脂容器內的密閉狀態最佳地保持。 In the above configuration, since the projections disposed on the lower side of the threaded portion are formed as the extended projections having a length in the circumferential direction longer than the circumferential length of the other projections, the female thread portion can be suppressed. The recommendation can suppress the pushing of the top surface of the cap. Therefore, it is possible to optimally hold the sealed state in the resin container by changing only the configuration of the cap.
以下，說明本發明的樹脂容器的蓋構造的最佳的態樣。但是，本發明的範圍不是藉由以下揭示的最佳的態樣例被限定。 Hereinafter, the best aspect of the lid structure of the resin container of the present invention will be described. However, the scope of the invention is not limited by the preferred embodiment disclosed below.
其中1個態樣是，前述延設突起部，是被設 在：從將前述帽最大限度捲緊在前述口部的最大捲緊狀態，橫跨為了將前述口部密閉只有最小限度所必要的量將前述帽捲緊的最小捲緊狀態，被配置於前述一螺紋部分的下側的範圍最佳。 One of the aspects is that the aforementioned extension protrusion is provided In the maximum winding state in which the cap is wound up to the maximum extent of the mouth, the minimum winding state in which the cap is wound up in an amount necessary to minimize the sealing of the mouth portion is disposed in the aforementioned state. The range of the underside of a threaded portion is optimal.
即，藉由帽將口部成為密閉狀態，沒有必要將帽成為最大限度為止捲緊口部的狀態(最大捲緊狀態)，只要成為最小限度所必要的捲緊量為止捲緊的話(最小捲緊狀態)，就可將口部成為密閉狀態。即，最大捲緊狀態及最小捲緊狀態之間的捲緊量的話就可以使口部成為密閉狀態。且，依據上述構成的話，因為在從最大捲緊狀態橫跨最小捲緊狀態使延設突起部被配置於一螺紋部分的下側的範圍設置延設突起部，所以無論最大捲緊狀態及最小捲緊狀態之間的任一捲緊量，延設突起部皆位於一螺紋部分的下側，可以更確度高地抑制母螺紋部的推舉。 In other words, when the mouth is in a sealed state, the cap is not required to be wound up to the maximum extent (maximum winding state), and it is required to be wound up as small as necessary (minimum roll) In the tight state, the mouth can be sealed. That is, when the amount of winding between the maximum winding state and the minimum winding state is reached, the mouth portion can be sealed. Further, according to the above configuration, since the extended projection is provided in a range in which the extended projection is disposed on the lower side of the threaded portion from the maximum winding state, the maximum winding state and the minimum are provided. Any winding amount between the crimped states, the extended projections are located on the lower side of the threaded portion, and the pushing of the female thread portion can be suppressed more surely.
其中1個態樣是，前述延設突起部的從前述帽的內周面的突出高度，比其他的前述突起部的突出高度高最佳。 In one of the aspects, the protruding height of the extending projection from the inner circumferential surface of the cap is preferably higher than the protruding height of the other protruding portions.
依據此構成的話，因為延設突起部與一螺紋部分抵接的面積變廣，所以可以更抑制母螺紋部的推舉，可以更抑制帽的頂面的推舉。 According to this configuration, since the area in which the extended projection portion abuts against the one screw portion is widened, the push of the female screw portion can be further suppressed, and the push of the top surface of the cap can be further suppressed.
其中1個態樣是，在前述延設突起部的先端緣具有稜角最佳。 One of the aspects is that the edge of the leading end portion of the extending protrusion is optimal.
依據此構成的話，藉由在延設突起部的先端緣具有稜角，延設突起部可更強地鉤住一螺紋部分。由 此，可以更抑制母螺紋部的推舉，可以更抑制帽的頂面的推舉。 According to this configuration, by providing the corners at the leading end edge of the extended projection, the extended projection can more strongly hook a threaded portion. by Thereby, the pushing of the female thread portion can be further suppressed, and the pushing of the top surface of the cap can be further suppressed.
其中1個態樣是，連接將前述帽中的前述口部的外周面密封的外密封部及前述帽的內周面之間的肋，是至少設在與前述一螺紋部分對應的部分最佳。 In one of the aspects, the rib that connects the outer seal portion that seals the outer peripheral surface of the mouth portion of the cap and the inner peripheral surface of the cap is at least provided in a portion corresponding to the one screw portion. .
即，帽的頂面的推舉，是起因於帽的頂面部分膨脹變形。且，依據此構成的話，因為在外密封部及帽的內周面之間設置肋，所以對於與一螺紋部分對應的部分，可以藉由肋抑制帽的頂面部分膨脹變形。因此，可以更抑制帽的頂面的推舉。 That is, the pushing of the top surface of the cap is caused by the expansion deformation of the top surface portion of the cap. Further, according to this configuration, since the rib is provided between the outer seal portion and the inner peripheral surface of the cap, the portion corresponding to the one screw portion can be expanded and deformed by the rib suppressing portion of the top surface portion of the cap. Therefore, the pushing of the top surface of the cap can be more suppressed.

對於本發明的樹脂容器的蓋構造的實施例參 照圖面進行說明。本實施例的樹脂容器的蓋構造S，是具有：在外周面11具有公螺紋部12的口部10、及在內周面21具有複數突起部23在圓周方向間斷地連結成為母螺紋部22的帽20，公螺紋部12，是在至少圓周方向的一部分，具有從口部10的先端至末端之間的螺峯數量是一條的一螺紋部分13a。且，將帽20的母螺紋部22螺合在口部10的公螺紋部12使口部10藉由帽20捲緊而密閉。且，具有延設突起部24、25，其是被配置於公螺紋部12中的一螺紋部分13a的下側的母螺紋部22中的突起部23，且圓周方向的長度比其他的突起部23的圓周方向的長度長。由此，可以補強防止母螺紋部22的推舉的力，可以抑制帽20的頂面26的推舉。以下詳細說明，將本實施例的蓋構造S，適用於作為樹脂容器的塑膠瓶1(以下稱為瓶1)的例。 Embodiment of the cover structure of the resin container of the present invention Explain according to the drawing. The lid structure S of the resin container of the present embodiment has the mouth portion 10 having the male screw portion 12 on the outer peripheral surface 11 and the plurality of projection portions 23 on the inner peripheral surface 21 intermittently connected to the female screw portion 22 in the circumferential direction. The cap 20, the male thread portion 12, is a portion of at least the circumferential direction, and has a threaded portion 13a having a number of spiral peaks from the tip end to the end of the mouth portion 10. Further, the female screw portion 22 of the cap 20 is screwed to the male screw portion 12 of the mouth portion 10, and the mouth portion 10 is wound by the cap 20 to be hermetically sealed. Further, the projections 24 and 25 are provided, and the projections 23 are disposed in the female thread portion 22 on the lower side of the threaded portion 13a of the male screw portion 12, and the length in the circumferential direction is longer than the other projections. The length of the circumferential direction of 23 is long. Thereby, the force for preventing the pushing of the female screw portion 22 can be reinforced, and the pushing of the top surface 26 of the cap 20 can be suppressed. Hereinafter, the cap structure S of the present embodiment is applied to an example of a plastic bottle 1 (hereinafter referred to as a bottle 1) as a resin container.
如第1圖所示，蓋構造S，是由：瓶1的口部10、及裝設在口部10的帽20所構成。口部10是在外周面11具有公螺紋部12，帽20是在內周面21具有母螺紋部22。且，在蓋構造S中，將帽20的母螺紋部22螺合在口部10的公螺紋部12使口部10藉由帽20捲緊而密閉。 As shown in Fig. 1, the lid structure S is composed of a mouth portion 10 of the bottle 1 and a cap 20 attached to the mouth portion 10. The mouth portion 10 has a male screw portion 12 on the outer peripheral surface 11, and the cap 20 has a female screw portion 22 on the inner peripheral surface 21. Further, in the lid structure S, the female screw portion 22 of the cap 20 is screwed to the male screw portion 12 of the mouth portion 10, and the mouth portion 10 is wound by the cap 20 to be hermetically sealed.
又，瓶1，可以是例如將聚乙烯、聚丙烯、聚對苯二甲酸乙二醇酯等的熱可塑性樹脂作為主材料，藉由二軸延伸吹塑成型等的延伸成形法而一體地成型。瓶1的容量無特別限定，可以是一般流通的200毫升~2升程 度。 Further, the bottle 1 may be integrally molded by, for example, a thermoplastic resin such as polyethylene, polypropylene or polyethylene terephthalate as a main material by an extension molding method such as biaxial stretching blow molding. . The capacity of the bottle 1 is not particularly limited, and may be a general flow of 200 ml to 2 liters. degree.
且充填在瓶1的液體無特別限定，例如可舉例飲料水、茶、果汁、咖啡、可可、清涼飲料水、酒精飲料、乳飲料、湯等的飲料、和高湯和醬油等的液體調味料等。又，本實施例中的蓋構造S，是被保管於氣氛溫度較高的場所時，除了內容物的熱膨脹以外液中藉由碳酸脫出發生，充填在瓶1使瓶1內的內壓變特別高的碳酸飲料情況時最佳。但是，即使不是碳酸飲料，因為也藉由內容物的熱膨脹使瓶1內的內壓提高，所以本實施例中的蓋構造S，對於非碳酸飲料也可以最佳使用。 The liquid to be filled in the bottle 1 is not particularly limited, and examples thereof include beverage water, tea, juice, coffee, cocoa, refreshing drink water, alcoholic beverages, milk beverages, soups, and the like, and liquid seasonings such as broth and soy sauce. . Further, in the case where the lid structure S in the present embodiment is stored in a place where the temperature of the atmosphere is high, the liquid is desorbed by carbonation in addition to the thermal expansion of the contents, and the internal pressure of the bottle 1 is filled in the bottle 1. The case of a particularly high carbonated beverage is optimal. However, even if it is not a carbonated beverage, since the internal pressure in the bottle 1 is improved by thermal expansion of the content, the lid structure S in the present embodiment can be optimally used for the non-carbonated beverage.
口部10中的公螺紋部12，從其外周面11朝徑方向(與外周面11垂直的方向)突出的螺峯13是在圓周方向呈螺旋狀間斷地連結者。且，公螺紋部12，是在至少圓周方向的一部分，具有從口部10的先端至末端間中的螺峯13的數量是一條的一螺紋部分13a。 The male screw portion 12 of the mouth portion 10 is spirally intermittently connected in the circumferential direction from the outer peripheral surface 11 toward the radial direction (the direction perpendicular to the outer peripheral surface 11). Further, the male screw portion 12 is a thread portion 13a having a single one of the number of the spiral peaks 13 from the tip end to the end portion of the mouth portion 10 in at least a part of the circumferential direction.
如第1、2圖所示，帽20中的母螺紋部22，是複數突起部23在圓周方向間斷地連結而成。且，使在形成於在縱方向並列的2個突起部23之間的間隙收容公螺紋部12的螺峯13的方式，使公螺紋部12(螺峯13)及母螺紋部22(突起部23)相補地形成。 As shown in Figs. 1 and 2, the female screw portion 22 of the cap 20 is formed by intermittently connecting the plurality of projections 23 in the circumferential direction. Further, the male screw portion 12 (spike 13) and the female screw portion 22 (protrusion portion) are formed so as to accommodate the peak 13 of the male screw portion 12 in the gap formed between the two projections 23 arranged in the longitudinal direction. 23) Complementary formation.
在母螺紋部22中，突起部23之中，圓周方向的長度比其他的突起部23的圓周方向的長度長的2個延設突起部24、25是連續地設置。且，此延設突起部24、25，是將口部10藉由帽20捲緊而密閉時，位於公螺 紋部12中的一螺紋部分13a的下側(口部10的末端側)地配置。 In the female screw portion 22, among the projection portions 23, the two extended projection portions 24, 25 having a length in the circumferential direction longer than the circumferential length of the other projection portions 23 are continuously provided. Further, the extended protrusions 24 and 25 are located in the male snail when the mouth portion 10 is wound by the cap 20 and sealed. The lower side (the end side of the mouth portion 10) of one of the thread portions 13a in the welt portion 12 is disposed.
又，為了藉由帽20將口部10作成密閉狀態，沒有必要將帽20作成最大限度為止捲緊在口部10的狀態(最大捲緊狀態)，只要成為最小限度所必要的捲緊量為止捲緊的話(最小捲緊狀態)，就可將口部10成為密閉狀態。即，最大捲緊狀態及最小捲緊狀態之間的捲緊量的話就可以將口部10作成密閉狀態。且，在本實施例中的蓋構造S中，最大捲緊狀態及最小捲緊狀態之間的捲緊量的差，是相當於以口部10的外周面11為圓周時的中心角35°的圓弧的長度。 Further, in order to seal the mouth portion 10 by the cap 20, it is not necessary to wind the cap 20 in the state of the mouth portion 10 (maximum winding state), and it is necessary to minimize the amount of winding required. When the winding is tight (the minimum winding state), the mouth portion 10 can be sealed. That is, the mouth portion 10 can be sealed in the case of the amount of winding between the maximum winding state and the minimum winding state. Further, in the cap structure S in the present embodiment, the difference in the amount of winding between the maximum winding state and the minimum winding state is equivalent to a central angle of 35° when the outer peripheral surface 11 of the mouth portion 10 is a circumference. The length of the arc.
在此，此各延設突起部24、25的長度，是相當於以口部10的外周面11為圓周時的中心角35°的圓弧的長度的長度。即，成為在中心角70°的圓弧的範圍設有延設突起部24、25的狀態。且，在最大捲緊狀態(第3圖參照)中，延設突起部24是被配置於一螺紋部分13a的下側，在最小捲緊狀態(第4圖參照)中，延設突起部25是被配置於一螺紋部分13a的下側。且，最大捲緊狀態及最小捲緊狀態之間的捲緊量時(第1圖參照)，兩延設突起部24、25是被配置於一螺紋部分13a的下側。即，延設突起部24、25，是設在：從最大捲緊狀態橫跨最小捲緊狀態，使延設突起部24或是/及延設突起部25被配置於一螺紋部分13a的下側的範圍的狀態。 Here, the length of each of the extended projections 24 and 25 is a length corresponding to the length of an arc of a central angle of 35° when the outer peripheral surface 11 of the mouth portion 10 is a circumference. In other words, the projections 24 and 25 are provided in a range of an arc having a central angle of 70°. Further, in the maximum winding state (refer to FIG. 3), the extended projection portion 24 is disposed on the lower side of the one screw portion 13a, and in the minimum winding state (refer to FIG. 4), the projection portion 25 is extended. It is disposed on the lower side of a threaded portion 13a. Further, in the case of the winding amount between the maximum winding state and the minimum winding state (refer to FIG. 1), the two extending projections 24 and 25 are disposed on the lower side of the one screw portion 13a. In other words, the extended projections 24 and 25 are disposed so as to extend from the maximum winding state to the minimum winding state, and the extended projections 24 or/and the extended projections 25 are disposed under the one threaded portion 13a. The state of the side range.
且第5圖(a)是顯示延設突起部24位於一 螺紋部分13a的下側的狀態，第5圖(b)是顯示其他的突起部23位於一螺紋部分13a的下側的狀態。如第5圖(a)、(b)所示，在延設突起部24中，從帽20的內周面21的突出高度，是比其他的突起部23的突出高度高。且，延設突起部24，是在其先端緣24a具有稜角。又，對於延設突起部25，也與延設突起部24同樣地，將從帽20的內周面21的突出高度，設成比其他的突起部23的突出高度高，在其先端緣具有稜角。 And Fig. 5(a) shows that the extended protrusion 24 is located at one The state of the lower side of the threaded portion 13a, and Fig. 5(b) shows the state in which the other projections 23 are located on the lower side of the threaded portion 13a. As shown in FIGS. 5(a) and 5(b), in the extended projection portion 24, the protruding height from the inner peripheral surface 21 of the cap 20 is higher than the protruding height of the other protruding portions 23. Further, the extended projection 24 has an edge at its leading edge 24a. Further, similarly to the extended projections 24, the protruding protrusions 25 are formed so as to have a higher protruding height from the inner peripheral surface 21 of the cap 20 than the other protruding portions 23, and have a leading edge at the tip end edge thereof. edges and corners.
如第5、6圖所示，在帽20的頂面26的內側面26a中，突出形成將口部10的外周面11密封的外密封部27。且，將連接此外密封部27及帽20的內周面21之間的肋28，設在當將口部10藉由帽20捲緊而密閉時與一螺紋部分13a對應的部分。更具體而言，在各延設突起部24、25的上方，各別設置肋28。 As shown in FIGS. 5 and 6, the outer seal portion 27 that seals the outer peripheral surface 11 of the mouth portion 10 is formed in the inner side surface 26a of the top surface 26 of the cap 20. Further, the rib 28 connecting the other sealing portion 27 and the inner circumferential surface 21 of the cap 20 is provided at a portion corresponding to the one screw portion 13a when the mouth portion 10 is wound by the cap 20 and sealed. More specifically, ribs 28 are provided separately above each of the extending protrusions 24 and 25.
接著，藉由帽20說明將口部10捲緊而密閉時的狀態。此時，如第1、3、4圖所示，在一螺紋部分13a的下側配置有延設突起部24或是/及延設突起部25。即，瓶1內的內壓提高，帽20的頂面26成為被推舉的狀態時，一螺紋部分13a是成為與延設突起部24或是/及延設突起部25卡合。防止對於一螺紋部分13a卡合的母螺紋部22的推舉的力通常會變弱，但是在本實施例中的蓋構造S中，因為卡合的延設突起部24、25是圓周方向的長度長，所以可以抑制其變形，由一螺紋部分13a抑制母螺紋部22的推舉。 Next, the state in which the mouth portion 10 is wound up and sealed is described by the cap 20. At this time, as shown in the first, third, and fourth figures, the extending projections 24 or/and the extending projections 25 are disposed on the lower side of the threaded portion 13a. That is, when the internal pressure in the bottle 1 is increased and the top surface 26 of the cap 20 is pushed, the one screw portion 13a is engaged with the extended projection portion 24 or/and the extended projection portion 25. The force for preventing the pushing of the female screw portion 22 for the engagement of the one threaded portion 13a is generally weakened, but in the cap configuration S in the present embodiment, since the engaged extending projections 24, 25 are in the circumferential direction It is long so that deformation thereof can be suppressed, and the pushing of the female thread portion 22 is suppressed by a threaded portion 13a.
且如第5圖(a)、(b)所示，在延設突起部24中，從帽20的內周面21的突出高度，是比其他的突起部23的突出高度高，由此，延設突起部24與一螺紋部分13a抵接的面積變廣。且，延設突起部24，是在其先端緣24a具有稜角，延設突起部24是藉由一螺紋部分13a被強力地鉤住。藉此，母螺紋部22的推舉更被抑制。又，延設突起部25，也與延設突起部24同形狀，也可達成同樣的作用效果。 Further, as shown in FIGS. 5(a) and 5(b), in the extended projection portion 24, the protruding height from the inner peripheral surface 21 of the cap 20 is higher than the protruding height of the other protruding portion 23, whereby The area in which the extended projection 24 abuts against the one screw portion 13a is widened. Further, the extended projection portion 24 has an edge at the leading end edge 24a, and the extended projection portion 24 is strongly hooked by a threaded portion 13a. Thereby, the pushing of the female thread portion 22 is further suppressed. Further, the extended projections 25 are also formed in the same shape as the extended projections 24, and the same operational effects can be achieved.
且因為將連接外密封部27及帽20的內周面21之間的肋28設在與一螺紋部分13a對應的部分，所以可以抑制帽20的頂面26膨脹變形，由此，帽20的頂面26的推舉更被抑制。 Further, since the rib 28 connecting the outer seal portion 27 and the inner peripheral surface 21 of the cap 20 is provided at a portion corresponding to the one threaded portion 13a, the top surface 26 of the cap 20 can be suppressed from being swollen and deformed, whereby the cap 20 is The pushing of the top surface 26 is more suppressed.
如以上，在本實施例中的蓋構造S中，因為可以將防止一螺紋部分13a中的母螺紋部22的推舉的力補強，並且抑制帽20的頂面26膨脹變形，所以可以抑制帽20的頂面26的推舉。如此，在本實施例中的蓋構造S中，只變更帽20的構成就可以將瓶1內的密閉狀態最佳地保持。 As described above, in the cap configuration S in the present embodiment, since the force for preventing the pushing of the female screw portion 22 in the one threaded portion 13a can be reinforced, and the top surface 26 of the cap 20 is suppressed from being swollen and deformed, the cap 20 can be suppressed. The top 26 is recommended. As described above, in the lid structure S of the present embodiment, only the configuration of the cap 20 can be changed to optimally hold the sealed state in the bottle 1.
