Description
本發明是有關於使用在寶特瓶等的容器之口部的可拆卸的樹脂製蓋子。 The present invention relates to a detachable resin cover for use in the mouth of a container such as a PET bottle.
以如此般樹脂製蓋子而言，廣泛使用具備：頂板部；筒部，其是從頂板部的周緣垂下；外環，其被形成在頂板部的內面且與容器口部的外周面接觸；以及內環，其被形成在頂板部的內面且與容器口部的內周面接觸，藉由以外環及長度(距離頂板部的垂直距離)比外環長的內環挾持容器口部而將容器密封者。 The cover made of such a resin is widely used: a top plate portion; a tubular portion that hangs from a peripheral edge of the top plate portion; and an outer ring that is formed on an inner surface of the top plate portion and that is in contact with an outer peripheral surface of the container mouth portion; And an inner ring formed on the inner surface of the top plate portion and in contact with the inner circumferential surface of the mouth portion of the container, and the inner ring and the length (the vertical distance from the top plate portion) are held by the inner ring longer than the outer ring Seal the container.
再者，近年來由於環保問題的意識高漲因此要求容器輕量化。在輕量化的對象著眼於容器口部的情況下，如專利文獻1所揭示般，有將上端面的厚度減少為形成螺條的部分的厚度的50%以下的手法。 Furthermore, in recent years, due to the high awareness of environmental protection issues, containers have been required to be lightweight. In the case where the lightweight object is focused on the mouth of the container, as disclosed in Patent Document 1, there is a method of reducing the thickness of the upper end surface to 50% or less of the thickness of the portion forming the spiral strip.
專利文獻1日本特開2014-37257號公報 Patent Document 1 Japanese Patent Laid-Open Publication No. 2014-37257
然而，如專利文獻1所揭示般將容器口部的前端部變薄的話，會造成容器口部的剛性降低，因此將樹脂製蓋子裝設在容器口部時，有因從外環來的壓力而發生容器口部的內倒(朝內部倒塌)的情況。 However, if the front end portion of the mouth portion of the container is thinned as disclosed in Patent Document 1, the rigidity of the mouth portion of the container is lowered. Therefore, when the resin cover is attached to the mouth of the container, there is pressure from the outer ring.

以下參照圖式針對本發明之樹脂製蓋子進行 說明。 Hereinafter, the resin cover of the present invention is carried out with reference to the drawings. Description.
本實施方式之樹脂製蓋子10，如第1圖所示般是使用於樹脂製的容器口部20。容器口部20從前端依序具有：藉著從內周面側切除而薄壁化的薄壁部20a、以及未薄壁化的本體部20b。薄壁部20a是形成朝向前端厚度逐漸變薄。 The resin cover 10 of the present embodiment is used for the container mouth portion 20 made of resin as shown in Fig. 1 . The container mouth portion 20 has, in order from the front end, a thin portion 20a that is thinned from the inner peripheral surface side and a body portion 20b that is not thinned. The thin portion 20a is formed to be gradually thinner toward the front end.
本實施方式之樹脂製蓋子10，如第1圖至第3圖所示般，具備：頂板部11；筒部12，其是從頂板部11的周緣垂下；外環13，其被形成在頂板部11的內面且與容器口部20的外周面接觸；以及內環14a、14b，其被形成在頂板部11的內面且與容器口部20的內周面接觸。 The resin cover 10 of the present embodiment includes a top plate portion 11 as shown in Figs. 1 to 3, a cylindrical portion 12 which is suspended from the periphery of the top plate portion 11, and an outer ring 13 which is formed on the top plate. The inner surface of the portion 11 is in contact with the outer circumferential surface of the container mouth portion 20, and the inner rings 14a, 14b are formed on the inner surface of the top plate portion 11 and are in contact with the inner circumferential surface of the container mouth portion 20.
雖然樹脂製蓋子10未特別限定材質、製法等，但可以例如使用聚乙烯、聚苯乙烯等的樹脂，將頂板部11、筒部12、外環13、內環14a、14b藉由一體地射出成型進行製造。 The resin cover 10 is not particularly limited to a material, a method, or the like. For example, the top plate portion 11, the tubular portion 12, the outer ring 13, and the inner rings 14a and 14b can be integrally molded by using a resin such as polyethylene or polystyrene. Molding for manufacturing.
樹脂製蓋子10的頂板部11是配合容器口部20的形狀而形成圓板狀，藉由將螺牙12a設在筒部12的內周面，而與形成在容器口部20的外周面的螺牙20a進行螺合，使樹脂製蓋子10裝設於容器口部20。 The top plate portion 11 of the resin cover 10 is formed into a disk shape in accordance with the shape of the container mouth portion 20, and is provided on the outer circumferential surface of the container mouth portion 20 by providing the thread 12a on the inner circumferential surface of the cylindrical portion 12. The thread 20a is screwed, and the resin cover 10 is attached to the container mouth 20.
外環13及內環14a、14b具有從頂板部11的內面突出的形狀。藉著在外環13的內周面接觸於容器口部20的外周面，內環14a、14b的外周面接觸於容器口部20的內周面，而密封容器。 The outer ring 13 and the inner rings 14a and 14b have a shape protruding from the inner surface of the top plate portion 11. By contacting the outer circumferential surface of the container mouth portion 20 on the inner circumferential surface of the outer ring 13, the outer circumferential surfaces of the inner rings 14a, 14b are in contact with the inner circumferential surface of the container mouth portion 20, and the container is sealed.
分別構成為內環14a與薄壁部20a接觸，內環14b與本體部20b接觸。藉由內環14a與薄壁部20a接觸，因剛性降低的薄壁部20a藉由內環14a支撐，所以可以將容器口部20的內倒予以抑制。再者，因為容器內藉由內環14a、14b形成雙重密封，所以可以使容器的密閉性提昇。 The inner ring 14a is in contact with the thin portion 20a, and the inner ring 14b is in contact with the main body portion 20b. Since the inner ring 14a is in contact with the thin portion 20a, the thin portion 20a whose rigidity is lowered is supported by the inner ring 14a, so that the inner bottom of the container mouth portion 20 can be suppressed. Further, since the inner seals 14a and 14b form a double seal in the container, the airtightness of the container can be improved.
雖然內環14a、14b的長度(距離頂板部11的垂直距離)是配合容器口部20的形狀予以適當設定即可，但較佳為將接觸於薄壁部20a的內環14a的長度，形成比接觸於薄壁部20a以外的部分的內環14b更短。 Although the length of the inner rings 14a and 14b (the vertical distance from the top plate portion 11) may be appropriately set in accordance with the shape of the mouth portion 20 of the container, it is preferable to form the length of the inner ring 14a contacting the thin portion 20a. The inner ring 14b is shorter than the portion other than the thin portion 20a.
外環13的形狀在本實施方式中，例示其外周面的一部分與容器口部20的內周面接觸的情況，但如果是可以與容器口部20進行接觸的形狀的話不特別加以限定，亦可以在第1圖至第3圖所示的形狀以外採用各種形狀。關於內環14a、14b亦相同。 In the present embodiment, the outer peripheral surface of the container mouth portion 20 is in contact with the inner peripheral surface of the container mouth portion 20, but the shape of the outer ring surface is not particularly limited. Various shapes can be employed in addition to the shapes shown in Figs. 1 to 3 . The same applies to the inner rings 14a and 14b.
以具有容器口部20的容器而言，雖未特別加 以限定，但例如可以適用於由聚苯二甲酸乙二酯等的合成樹脂所製造的飲料用等的樹脂製容器上。尤其是適合使用在果汁飲料、運動飲料、及茶等等，在高溫狀態下將內容物進行填充的樹脂製容器。 In the case of a container having a mouth 20 of the container, although it is not particularly added In a limited manner, for example, it can be applied to a resin container made of a synthetic resin such as polyethylene terephthalate or the like. In particular, it is suitable for use in a resin container in which a content is filled in a high temperature state in a fruit juice beverage, a sports drink, a tea, or the like.
外環13係如第4圖所示般，從內周面側傾斜切除成朝向前端厚度逐漸變薄，在平面視中，外環13的基部的徑向內側的端部，亦可構成比前述容器口部20的前端部的徑向外側的端部更靠內側。藉此，以外環13對於容器口部20咬入的方式接觸，可以使容器的密閉性提昇。 As shown in Fig. 4, the outer ring 13 is cut obliquely from the inner peripheral surface side to be gradually thinner toward the tip end, and the radially inner end portion of the base portion of the outer ring 13 may be formed in the plan view as compared with the above. The radially outer end portion of the front end portion of the container mouth portion 20 is located further inside. Thereby, the outer ring 13 comes into contact with the container mouth portion 20, and the airtightness of the container can be improved.
雖然在上述實施方式中，例示容器口部20以薄壁部20a和本體部20b構成的情況，但容器口部20的構造未限定於此，亦可將容器口部20整體予以薄壁化，而將容器口部20僅以薄壁部20a構成。 In the above embodiment, the case where the container mouth portion 20 is configured by the thin portion 20a and the main body portion 20b is exemplified, but the structure of the container mouth portion 20 is not limited thereto, and the entire container mouth portion 20 may be thinned. The container mouth portion 20 is formed only by the thin portion 20a.
雖然在上述實施方式中，例示薄壁部20a是將容器口部20的內周面切除成縱剖面為直線狀的形狀的情況，但薄壁部20a的形狀不限定於此。例如，可為將容器口部20的內周面切除成縱剖面朝內側凸出的曲線狀形狀，亦可為將切除成縱剖面為直線狀形狀的部分和切除成縱剖面朝內側凸出的曲線狀形狀的部分予以組合。 In the above-described embodiment, the thin portion 20a is exemplified in a case where the inner peripheral surface of the container mouth portion 20 is cut into a linear shape in a vertical cross section, but the shape of the thin portion 20a is not limited thereto. For example, the inner peripheral surface of the container mouth portion 20 may be cut into a curved shape in which the longitudinal section protrudes inward, or the portion cut into a linear shape in the longitudinal section and the portion cut out in the longitudinal section may be protruded inward. The portions of the curved shape are combined.
再者，薄壁部20a亦可形成如第5圖所示般，從前端依序具有第1薄壁部20a-1和第2薄壁部20a-2，該第2薄壁部20a-2是與第1薄壁部20a-1形狀不同，並且 最大厚度比第1薄壁部20a-1更厚。在此情況下，較佳構成為內環14a接觸於第1薄壁部20a-1，內環14b接觸於第2薄壁部20a-2。 Further, as shown in Fig. 5, the thin portion 20a may have a first thin portion 20a-1 and a second thin portion 20a-2 sequentially from the front end, and the second thin portion 20a-2 Is different from the shape of the first thin portion 20a-1, and The maximum thickness is thicker than the first thin portion 20a-1. In this case, it is preferable that the inner ring 14a is in contact with the first thin portion 20a-1, and the inner ring 14b is in contact with the second thin portion 20a-2.
此外，如第5圖所示般，在容器口部20是由薄壁部20a及本體部20b所構成的情況下，亦可讓內環14a接觸於第1薄壁部20a-1，讓內環14b接觸於本體部20b，該薄壁部20a是以第1薄壁部20a-1及第2薄壁部20a-2所構成。 Further, as shown in Fig. 5, when the container mouth portion 20 is composed of the thin portion 20a and the main body portion 20b, the inner ring 14a may be brought into contact with the first thin portion 20a-1. The ring 14b is in contact with the main body portion 20b, and the thin portion 20a is composed of the first thin portion 20a-1 and the second thin portion 20a-2.
再者，亦可形成三個內環，讓內環分別一個一個接觸於第1薄壁部20a-1、第2薄壁部20a-2、以及本體部20b。 Further, three inner rings may be formed, and the inner rings may be in contact with the first thin portion 20a-1, the second thin portion 20a-2, and the main body portion 20b, respectively.
雖然在上述實施方式中，針對形成兩個內環的情況及形成三個內環的情況做例示，但內環的數量未限定於此，亦可為一個，或四個以上。在內環的數量為一個的情況下，內環較合適為在前端部形成朝內環的徑向外側且曲面狀凸出的凸曲面部的形狀，或複數個內環形成一體的形狀。 In the above embodiment, the case where the two inner rings are formed and the case where the three inner rings are formed are exemplified, but the number of the inner rings is not limited thereto, and may be one, or four or more. In the case where the number of the inner rings is one, the inner ring is preferably formed in a shape in which the front end portion is formed in a curved outer surface that is convex outward in the radial direction of the inner ring, or a plurality of inner rings are integrally formed.
第6圖是表示將內環的形狀，構成為在前端部形成朝內環的徑向外側且曲面狀凸出的凸曲面部的情況的重要部分擴大圖。在第6圖，內環14c是凸曲面部14c-1形成於前端部，凸曲面部14c-1與薄壁部20a接觸。藉此，對於容器口部20，不只從橫向亦可以從縱向施加壓力。 Fig. 6 is an enlarged view of an important part showing a shape in which the inner ring is formed in a convex curved surface portion in which the front end portion is formed radially outward of the inner ring and curved in a curved shape. In Fig. 6, the inner ring 14c has a convex curved surface portion 14c-1 formed at the front end portion, and the convex curved surface portion 14c-1 is in contact with the thin portion 20a. Thereby, with respect to the mouth portion 20 of the container, pressure can be applied not only from the lateral direction but also from the longitudinal direction.
此外，凸曲面部14c-1只要在內環14c的至少 前端部形成即可，亦可在內環14c的外周面整體形成凸曲面部14c-1。 Further, the convex curved surface portion 14c-1 is only required to be at least in the inner ring 14c The front end portion may be formed, or the convex curved surface portion 14c-1 may be formed on the entire outer circumferential surface of the inner ring 14c.
第7圖是作為複數個內環形成一體的形狀的內環(一體型的內環)的例子，表示將內環的形狀構成為在外周面形成複數個朝內環的徑向外側凸出，並且與容器口部的內周面接觸的凸出部的情況下的重要部分擴大圖。在第7圖，內環14d的外周面，形成朝內環的徑向外側凸出的兩個的凸出部14d-1、14d-2，凸出部14d-1與薄壁部20a接觸，凸出部14d-2與本體部20b接觸。藉此，可以藉著一個的內環14d來接觸於薄壁部20a及本體部20b的雙方，而進行容器口部20的支撐及容器內部的密封。 Fig. 7 is an example of an inner ring (integral inner ring) having a shape in which a plurality of inner rings are integrally formed, and the inner ring is formed to have a shape in which a plurality of inwardly facing inner rings are formed on the outer peripheral surface. Further, an important portion of the projection in contact with the inner peripheral surface of the mouth portion of the container is enlarged. In Fig. 7, the outer peripheral surface of the inner ring 14d is formed with two projecting portions 14d-1 and 14d-2 projecting outward in the radial direction of the inner ring, and the projecting portion 14d-1 is in contact with the thin portion 20a. The projection 14d-2 is in contact with the body portion 20b. Thereby, both the thin portion 20a and the main body portion 20b can be contacted by one inner ring 14d, and the container mouth portion 20 can be supported and the inside of the container can be sealed.
雖然凸出部14d-1、14d-2的長度(距離基部的水平距離)是配合容器口部20的形狀予以適當設定即可，但較佳為將接觸於薄壁部20a的凸出部14d-1的長度，形成比接觸於薄壁部20a以外的部分的凸出部14d-2更長。 Although the length of the protruding portions 14d-1 and 14d-2 (the horizontal distance from the base portion) is appropriately set in accordance with the shape of the mouth portion 20 of the container, it is preferable to have the protruding portion 14d which is in contact with the thin portion 20a. The length of -1 is longer than the projection 14d-2 which is in contact with the portion other than the thin portion 20a.
在如前述之第5圖所示般，將內環14d使用於具有以第1薄壁部20a-1及第2薄壁部20a-2所構成的薄壁部20a的容器口部20的情況下，較佳構成為凸出部14d-1接觸於第1薄壁部20a-1，凸出部14d-2接觸於第2薄壁部20a-2。 As shown in the fifth embodiment, the inner ring 14d is used for the container mouth portion 20 having the thin portion 20a formed by the first thin portion 20a-1 and the second thin portion 20a-2. Preferably, the protruding portion 14d-1 is in contact with the first thin portion 20a-1, and the protruding portion 14d-2 is in contact with the second thin portion 20a-2.
再者，在將內環14d，如前述之第5圖所示般，使用於以薄壁部20a及本體部20b所構成的容器口部20的情況下，亦可讓內環14a接觸於第1薄壁部20a-1， 讓內環14b接觸於本體部20b，該薄壁部20a是以第1薄壁部20a-1及第2薄壁部20a-2所構成。 Further, when the inner ring 14d is used for the container mouth portion 20 formed by the thin portion 20a and the main body portion 20b as shown in the fifth embodiment, the inner ring 14a may be in contact with the inner ring 14a. 1 thin wall portion 20a-1, The inner ring 14b is brought into contact with the main body portion 20b, and the thin portion 20a is composed of the first thin portion 20a-1 and the second thin portion 20a-2.
再者，亦可於內環形成三個凸出部，分別讓凸出部一個一個接觸於第1薄壁部20a-1、第2薄壁部20a-2、本體部20b。 Further, three projections may be formed in the inner ring, and the projections may be in contact with the first thin portion 20a-1, the second thin portion 20a-2, and the main portion 20b, respectively.
此外，之前所說明的一體型的內環的形狀，始終是作為適合的例示而舉出，一體型的內環的形狀不限定於此。例如，亦可如第8圖所示的內環14e般，配置成將外周面形成從前端部側切除的形狀，且切除的部分是面向薄壁部20a和本體部20b的邊界，從而讓內環14e的外周面接觸於薄壁部20a及本體部20b的雙方。 Further, the shape of the integral inner ring described above is always exemplified as a suitable example, and the shape of the integral inner ring is not limited thereto. For example, as in the inner ring 14e shown in Fig. 8, the outer peripheral surface may be formed in a shape cut away from the front end side, and the cut portion may face the boundary between the thin portion 20a and the main body portion 20b, thereby allowing the inner portion The outer peripheral surface of the ring 14e is in contact with both the thin portion 20a and the main body portion 20b.
再者，雖然未圖示，但亦可在內環的外周面，形成一個朝內環的徑向外側凸出的凸出部，而讓此凸出部接觸於薄壁部(或第1薄壁部)，並且讓內環的凸出部以外的外周面接觸於本體部(或第2薄壁部)。 Further, although not shown, a convex portion that protrudes outward in the radial direction of the inner ring may be formed on the outer circumferential surface of the inner ring, and the convex portion may be in contact with the thin portion (or the first thin portion). The wall portion) is in contact with the outer peripheral surface of the inner ring (the second thin portion).
