Description

樹脂製蓋子 Resin cover

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(無可例示該先前技術的適當文獻)。 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 The container is sealed (the appropriate literature of this prior art is not exemplified).

已有將高溫的內容物充填在保特瓶等容器的俗稱熱充填法的方法。在熱充填法中，內環接觸於高溫的內容物，因此時的熱而有導致內環的變形及彈力減弱(劣 化)發生的情況。因此，造成內環對於容器口部的推壓力降低，在容器的密閉性降低的方面尚有改善的餘地。 There is a method known as a hot filling method in which a high-temperature content is filled in a container such as a bottle. In the hot filling method, the inner ring is in contact with the high temperature content, and thus the heat causes the inner ring to be deformed and the elastic force is weakened (inferior (the situation). Therefore, the pressing force of the inner ring against the mouth of the container is lowered, and there is still room for improvement in the sealing property of the container.

本發明是有鑑於如此般狀況而發明，其目地在於提供即使在進行熱充填法的情況下，依舊可以維持容器的閉密性良好的樹脂製蓋子。 The present invention has been made in view of such circumstances, and it is an object of the invention to provide a resin cover which can maintain a good sealing property of a container even when a hot charging method is performed.

本發明之樹脂製蓋子的特徵構造，在於裝設在容器口部，具備：頂板部；筒部，其係從前述頂板部的周緣垂下；以及內環，其係形成在前述頂板部的內面且與前述容器口部的內周面接觸，裝設在前述容器口部時，至少將前述容器口部的內周面予以雙重密封。 The resin cap of the present invention is characterized in that it is attached to the mouth of the container and includes a top plate portion, a tubular portion that is suspended from the periphery of the top plate portion, and an inner ring that is formed on the inner surface of the top plate portion. Further, when it is in contact with the inner peripheral surface of the mouth portion of the container and is attached to the mouth portion of the container, at least the inner peripheral surface of the mouth portion of the container is double-sealed.

根據該構成，藉著至少將容器口部的內周面予以雙重密封，即使密封部的其中一個因與內容物的接觸而發生變形及彈力減弱，因為未與內容物接觸的其他的密封部仍舊確保其密封性，所以可以維持容器的密閉性良好。 According to this configuration, by at least sealing the inner peripheral surface of the mouth portion of the container, even if one of the seal portions is deformed due to contact with the contents and the elastic force is weakened, the other seal portions that are not in contact with the contents are still old. The sealing property is ensured, so that the sealing property of the container can be maintained.

本發明的進一步的特徵構造，在於在前述內環的外周面形成複數個凸出部，藉著裝設在前述容器口部時，前述複數個凸出部與前述容器口部的內周面接觸，而至少將前述容器口部的內周面予以雙重密封。 According to a further feature of the present invention, a plurality of projections are formed on an outer circumferential surface of the inner ring, and the plurality of projections are in contact with an inner circumferential surface of the mouth of the container when the mouth portion of the container is installed. At least the inner peripheral surface of the mouth of the container is double sealed.

根據該構成，利用形成在內環的凸出部，可以容易實現至少將容器口部的內周面予以雙重密封的構造。 According to this configuration, it is possible to easily realize a structure in which at least the inner peripheral surface of the mouth portion of the container is double-sealed by the protruding portion formed in the inner ring.

本發明的進一步的特徵構造，在於裝設在前述容器口部時，前述頂板部是於縱剖面觀看下，在比前述容器口部更靠內側，形成朝著前述容器口部側凸出般凹陷的凹陷部，前述內環是形成在前述凹陷部，藉著裝設在前述容器口部時，前述凹陷部和前述內環與前述容器口部的內周面進行接觸，而至少將前述容器口部的內周面予以雙重密封。 According to a further feature of the present invention, in the case of the mouth portion of the container, the top plate portion is formed on the inner side of the mouth portion of the container in a longitudinal section, and is formed to be convex toward the mouth side of the container. In the recessed portion, the inner ring is formed in the recessed portion, and when the container mouth portion is installed, the recessed portion and the inner ring are in contact with an inner peripheral surface of the container mouth portion, and at least the container mouth portion is The inner circumferential surface is double sealed.

根據該構成，藉著利用內環和凹陷部進行密封(形成密封部)，可以容易實現至少將容器口部的內周面予以雙重密封的構造。 According to this configuration, by sealing (forming the sealing portion) by the inner ring and the depressed portion, it is possible to easily realize a structure in which at least the inner peripheral surface of the container mouth portion is double-sealed.

再者，因為藉著將內環形成在凹陷部，可以讓內環比以往更短，所以可以提高內環的剛性，抑制內環的變形。 Further, since the inner ring is formed in the depressed portion, the inner ring can be made shorter than in the related art, so that the rigidity of the inner ring can be improved and the deformation of the inner ring can be suppressed.

再者，因為可以將內環和容器口部兩者的接觸部分遠離容器口部的前端部，所以可以防止容器的密閉提早解除。 Further, since the contact portion between the inner ring and the mouth portion of the container can be separated from the front end portion of the mouth portion of the container, the sealing of the container can be prevented from being released early.

而且，因為可以藉由凹陷部將容器口部從內周面側予以支撐，所以可以防止在將外環設置在樹脂製蓋子的情況下，因從外環來的推壓力而發生容器口部的內倒情形。 Further, since the container mouth portion can be supported from the inner peripheral surface side by the recessed portion, it is possible to prevent the container mouth portion from being generated by the pressing force from the outer ring when the outer ring is placed on the resin cover. Inside the situation.

以下參照圖式針對本發明之樹脂製蓋子進行說明。 The resin cap of the present invention will be described below with reference to the drawings.

〔實施方式1〕 [Embodiment 1]

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。 The resin cover 10 of the present embodiment is used for the container mouth portion 20 made of resin as shown in Fig. 1 .

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14，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 ring 14 is formed on the inner surface of the top plate portion 11 and is 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14藉由一體射出成型進行製造。 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 ring 14 can be manufactured by integral injection molding using a resin such as polyethylene or polystyrene. .

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裝設在容器口部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14具有從頂板部11的內面凸出的形狀。藉著在外環13的內周面接觸於容器口部20的外周面，內環14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 ring 14 have a shape that protrudes 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 surface of the inner ring 14 contacts the inner circumferential surface of the container mouth portion 20, and the container is sealed.

內環14是在外周面形成兩個朝著內環14的徑向外側凸出的凸出部14a，從縱剖面觀看形狀是呈現梳刀狀。藉著兩個凸出部14a與容器口部20的內周面進行接觸，將容器口部20的內周面予以雙重密封。兩個凸出部14a之中，雖然形成在內環14的前端部側的部分有因為與內容物的接觸而發生變形及彈力減弱的可能性，但因為形成在內環14的基部側的部分未與內容物接觸，所以可以維持良好的密封性。 The inner ring 14 has two projections 14a projecting outward in the radial direction of the inner ring 14 on the outer peripheral surface, and the shape viewed from the longitudinal section is a comb-like shape. The inner peripheral surface of the container mouth portion 20 is double-sealed by the two projecting portions 14a coming into contact with the inner peripheral surface of the container mouth portion 20. Among the two projections 14a, the portion formed on the front end side of the inner ring 14 is deformed by the contact with the contents, and the elastic force is weakened, but the portion formed on the base side of the inner ring 14 is formed. It is not in contact with the contents, so that good sealing can be maintained.

凸出部14a是形成曲面狀凸出，因此可以讓將樹脂製蓋子10裝設在容器口部20時的抵抗(封蓋抵抗)降低。 Since the projections 14a are formed in a curved shape, the resistance (cover resistance) when the resin cover 10 is attached to the container mouth portion 20 can be reduced.

內環14是形成從基部附近朝著基部厚度增 加，在本實施方式中形成為除了凸出部14a的部分之外以基部最厚。因此，可以讓內環14不易彈力減弱。 The inner ring 14 is formed to increase in thickness from the vicinity of the base toward the base In the present embodiment, the base portion is formed to be thickest except for the portion of the projection portion 14a. Therefore, the inner ring 14 can be made less elastic.

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。 The container having the container mouth portion 20 is not particularly limited, and can be applied to, for example, 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.

〔其他實施方式〕 [Other Embodiments]

雖然在上述之實施方式中，針對將凸出部14a形成在內環14的外周面的前端部和大致中央部的情況進行說明，但形成凸出部14a的位置不限定於此。例如，亦可將兩個凸出部14a形成在內環14的外周面的大致中央部。 In the above-described embodiment, the case where the protruding portion 14a is formed at the front end portion and the substantially central portion of the outer circumferential surface of the inner ring 14 will be described, but the position at which the protruding portion 14a is formed is not limited thereto. For example, the two protruding portions 14a may be formed at substantially the center of the outer circumferential surface of the inner ring 14.

雖然在上述之實施方式中，針對將兩個凸出部14a以相同形狀形成的情況進行說明，但亦可形成彼此不同的形狀。 In the above-described embodiment, the case where the two projections 14a are formed in the same shape will be described, but the shapes different from each other may be formed.

在上述之實施方式中，雖然針對藉著讓形成在內環14的兩個凸出部14a與容器口部20的內周面進行接觸而將容器口部20的內周面予以雙重密封的情況進行說明，但將容器口部20的內周面予以雙重密封的手法不限定於此。例如，亦可如第4圖及第5圖所示般，於縱剖面觀看下比容器口部20更靠內側，形成朝著容器口部20側凸出般凹陷的凹陷部15，並且將內環14形成在凹陷部15，藉著讓凹陷部15和內環14與容器口部20的內周面 進行接觸，將容器口部20的內周面予以雙重密封。在該方式中，因為從頂板部11至容器口部20為止的距離變短，可以將內環14變得比以往更短，所以可以提高內環14的剛性，抑制內環14的變形。 In the above-described embodiment, the inner peripheral surface of the container mouth portion 20 is double-sealed by bringing the two projecting portions 14a formed in the inner ring 14 into contact with the inner peripheral surface of the container mouth portion 20. Although the method of double sealing the inner circumferential surface of the container mouth portion 20 is not limited thereto. For example, as shown in FIG. 4 and FIG. 5, the inside of the container mouth portion 20 may be formed on the inner side of the container mouth portion 20 as viewed in the longitudinal section, and a recessed portion 15 which is convexly recessed toward the container mouth portion 20 side may be formed, and The ring 14 is formed in the recess 15 by letting the recess 15 and the inner ring 14 and the inner peripheral surface of the container mouth 20 Contact is made to double seal the inner circumferential surface of the container mouth portion 20. In this aspect, since the distance from the top plate portion 11 to the container mouth portion 20 is shortened, the inner ring 14 can be made shorter than the conventional one, so that the rigidity of the inner ring 14 can be increased and the deformation of the inner ring 14 can be suppressed.

再者，因為可以將內環14和容器口部20兩者的接觸部分遠離容器口部20的前端部，所以可以防止容器的密閉提早解除。 Further, since the contact portion between the inner ring 14 and the container mouth portion 20 can be separated from the front end portion of the container mouth portion 20, the sealing of the container can be prevented from being released early.

而且，因為凹陷部15可以由與從外環13來的推壓力相對向的方向將容器口部20予以支撐，所以可以抑制容器口部20的內倒發生。 Moreover, since the recessed portion 15 can support the container mouth portion 20 in a direction opposed to the urging force from the outer ring 13, it is possible to suppress the occurrence of the inside of the container mouth portion 20.

凹陷15的外周面只要形成沿容器口部的內周面的形狀，且可與容器口部的內周面滑動即可。凹陷15的內周面的形狀未特別限定，可採用圓形、四角形等的各種形狀。 The outer peripheral surface of the recess 15 may have a shape along the inner peripheral surface of the mouth portion of the container, and may slide with the inner peripheral surface of the mouth portion of the container. The shape of the inner circumferential surface of the recess 15 is not particularly limited, and various shapes such as a circular shape and a quadrangular shape may be employed.

雖然在第4圖及第5圖中，內環14在前端部具有朝著內環14的徑向外側凸出的凸出部14a，且讓凸出部14a與容器口部20的內周面進行接觸，但亦可如第6圖所示般，將內環14形成直線狀的形狀，而讓其前端部與容器口部20的內周面進行接觸。在該方式中，因為可以讓內環14相對於容器口部20的軸線方向從傾斜方向接觸於容器口部20，所以可以加強內環14對於容器口部20的推壓力。 In FIGS. 4 and 5, the inner ring 14 has a projection 14a projecting toward the radially outer side of the inner ring 14 at the front end portion, and the inner peripheral surface of the projection portion 14a and the container mouth portion 20 is provided. Although the contact is made, the inner ring 14 may be formed in a linear shape as shown in Fig. 6, and the front end portion thereof may be brought into contact with the inner peripheral surface of the container mouth portion 20. In this manner, since the inner ring 14 can be brought into contact with the container mouth portion 20 from the oblique direction with respect to the axial direction of the container mouth portion 20, the pressing force of the inner ring 14 with respect to the container mouth portion 20 can be enhanced.

雖然在上述之實施方式中，針對將容器口部20的內周面予以雙重密封的情況，換言之將兩個密封部 形成在容器口部20的內周面的情況進行說明，但形成在容器口部20的內周面的密封部的數量不限定於此，亦可三個以上。例如，如果是形成三個密封部的情況的話，只要在內環14的外周面形成三個凸出部14a，且讓三個的凸出部14a與容器口部的內周面進行接觸即可。再者，亦可將具有兩個凸出部14a的內環14形成在第4圖及第5圖所示的凹陷部15，讓凹陷部15和兩個凸出部14a與容器口部20的內周面進行接觸。 In the above embodiment, in the case of double sealing the inner circumferential surface of the container mouth portion 20, in other words, the two sealing portions The case where it is formed in the inner peripheral surface of the container mouth part 20 is demonstrated, However, the number of the sealing part formed in the inner peripheral surface of the container mouth part 20 is not limited to this, and may be three or more. For example, if three sealing portions are formed, three protruding portions 14a are formed on the outer circumferential surface of the inner ring 14, and the three protruding portions 14a are brought into contact with the inner circumferential surface of the container mouth portion. . Furthermore, the inner ring 14 having the two projections 14a may be formed in the recessed portion 15 shown in FIGS. 4 and 5, and the recessed portion 15 and the two projections 14a and the container mouth portion 20 may be formed. The inner peripheral surface is in contact.

此外，到目前為止所說明的至少將容器口部20的內周面予以雙重密封手法，僅作為適合的範例而例舉，亦可使用其他的手法。例如，亦可將內環14的前端部分岔，讓其前端部和容器口部20的內周面進行接觸。 Further, at least the inner peripheral surface of the container mouth portion 20 has been double-sealed as described so far, and is merely exemplified as a suitable example, and other methods may be used. For example, the front end portion of the inner ring 14 may be twisted so that the front end portion thereof comes into contact with the inner circumferential surface of the container mouth portion 20.
