Description

本発明は、注出容器に関する。 The present invention relates to a dispensing container.

従来から、例えば下記特許文献１に示されるような、口部を有する有底筒状の容器本体と、口部から上方に向けて延び、上端開口が容器本体内に連通した注出筒部材と、を備えた注出容器が知られている。 Conventionally, as shown in, for example, Patent Document 1 below, there is known a pouring container that includes a bottomed, cylindrical container body having a mouth, and a pouring tube member that extends upward from the mouth and has an upper end opening that communicates with the inside of the container body.

実開平４－８９７５４号公報Japanese Utility Model Application Publication No. 4-89754

従来の注出容器では、内容物を使い切ったときに、注出筒部材を口部から外して、口部の上端開口を開放した後に、例えば他の内容物を口部から容器本体内に注入し、その後、再び注出筒部材を口部に装着したものが使用される、つまり注出容器が再利用されるおそれが考えられる。
特に、容器本体内の内容物が、化粧品等の薬剤の場合には、用法や用量等の適切な使用が損なわれるおそれがあり、注出容器の前述した再利用が懸念される。 With conventional pouring containers, when the contents are used up, the pouring tube member is removed from the mouth, the upper opening of the mouth is opened, and then, for example, other contents are poured into the container body through the mouth, and then the pouring tube member is attached to the mouth again for use, i.e., the pouring container may be reused.
In particular, when the contents in the container body are medicines such as cosmetics, there is a risk that proper use such as directions for use and dosage may be compromised, and there are concerns about the aforementioned reuse of the pouring container.

本発明は、注出筒部材を口部から外しにくくすることができる注出容器を提供する。 The present invention provides a pouring container that makes it difficult for the pouring tube member to be removed from the mouth.

本発明の一態様に係る注出容器は、口部を有する有底筒状の容器本体と、前記口部に装着され、前記容器本体内に連通する連通孔が形成された中栓部材と、前記口部から上方に向けて延び、上端開口が前記連通孔に連通する注出筒部材と、を備え、前記注出筒部材には、前記口部内に嵌合された嵌合筒が設けられ、前記口部の内周面に、係止凹部が形成され、前記嵌合筒の外周面に、前記係止凹部に係止された係止突部が形成されている。 The pouring container according to one aspect of the present invention comprises a bottomed cylindrical container body having a mouth, a stopper member attached to the mouth and having a through hole that communicates with the inside of the container body, and a pouring tube member extending upward from the mouth and having an upper end opening that communicates with the through hole, the pouring tube member being provided with a fitting tube that is fitted into the mouth, a locking recess formed on the inner circumferential surface of the mouth, and a locking protrusion that is locked to the locking recess formed on the outer circumferential surface of the fitting tube.

注出筒部材の嵌合筒が、口部内に嵌合され、口部の内周面に、係止凹部が形成され、嵌合筒の外周面に、係止凹部に係止された係止突部が形成されているので、例えば注出筒部材と口部との間に工具等を差し込みにくくなり、係止突部と係止凹部との係合を外しにくくすることが可能になり、注出筒部材を口部から外しにくくすることができる。 The fitting tube of the dispensing tube member is fitted into the mouth portion, a locking recess is formed on the inner peripheral surface of the mouth portion, and a locking protrusion that is locked into the locking recess is formed on the outer peripheral surface of the fitting tube. This makes it difficult to insert tools, for example, between the dispensing tube member and the mouth portion, and makes it difficult to disengage the locking protrusion from the locking recess, making it difficult to remove the dispensing tube member from the mouth portion.

前記中栓部材には、前記嵌合筒内に挿入され、前記嵌合筒の内周面に当接、若しくは近接した支持壁部が設けられてもよい。 The plug member may be provided with a support wall portion that is inserted into the fitting tube and abuts against or is close to the inner peripheral surface of the fitting tube.

中栓部材に、嵌合筒内に挿入され、嵌合筒の内周面に当接、若しくは近接した支持壁部が設けられているので、嵌合筒を支持壁部に当接させることで、嵌合筒の縮径変形を規制することが可能になり、係止突部と係止凹部との係合を確実に外しにくくすることができる。 The plug member is provided with a support wall portion that is inserted into the fitting tube and abuts or is close to the inner peripheral surface of the fitting tube. By abutting the fitting tube against the support wall portion, it is possible to restrict the deformation of the fitting tube by reducing its diameter, and it is possible to reliably prevent the engagement between the locking protrusion and the locking recess from coming loose.

前記支持壁部の外周面のうち、上端部は、前記嵌合筒の内周面に当接し、上端部より下方に位置する下部は、前記嵌合筒の内周面から径方向の内側に離れて近接し、前記係止突部は、前記支持壁部の上端部より下方に位置してもよい。 The upper end of the outer peripheral surface of the support wall abuts against the inner peripheral surface of the fitting tube, and the lower portion located below the upper end is close to and spaced radially inward from the inner peripheral surface of the fitting tube, and the locking protrusion may be located below the upper end of the support wall.

支持壁部の外周面のうち、上端部が、嵌合筒の内周面に当接し、上端部より下方に位置する下部が、嵌合筒の内周面から径方向の内側に離れて近接しているので、嵌合筒の上端部内に支持壁部の上端部を嵌合して、注出筒部材および中栓部材を互いに連結した状態で、これらを口部に装着する際、嵌合筒の係止突部が、口部の内周面を摺動して係止凹部に到達するまでの間に、嵌合筒の下部を径方向の内側に向けて弾性変形させることが可能になり、注出容器を容易に組み立てることができる。 The upper end of the outer peripheral surface of the support wall abuts against the inner peripheral surface of the fitting tube, and the lower part, located below the upper end, is close to but away from the inner peripheral surface of the fitting tube in the radial direction. Therefore, when the upper end of the support wall is fitted into the upper end of the fitting tube and the spouting tube member and the inner plug member are attached to the mouth in a state where they are connected to each other, the lower part of the fitting tube can be elastically deformed radially inward while the locking protrusion of the fitting tube slides along the inner peripheral surface of the mouth and reaches the locking recess, making it easy to assemble the spouting container.

前記注出筒部材には、前記嵌合筒から径方向の外側に向けて突出して、前記口部の上端開口縁を覆い、かつ前記口部の上端開口縁に当接、若しくは近接する被覆壁部が設けられてもよい。 The dispensing tube member may be provided with a covering wall portion that protrudes radially outward from the fitting tube, covers the upper opening edge of the mouth portion, and abuts against or is adjacent to the upper opening edge of the mouth portion.

注出筒部材に、嵌合筒から径方向の外側に向けて突出して、口部の上端開口縁を覆い、かつ口部の上端開口縁に当接、若しくは近接する被覆壁部が設けられているので、嵌合筒の外周面と口部の内周面との間に工具等を差し込みにくくすることが可能になり、係止突部と係止凹部との係合を確実に外しにくくすることができる。 The dispensing tube member is provided with a covering wall portion that protrudes radially outward from the fitting tube and covers the upper opening edge of the mouth portion, and abuts or is close to the upper opening edge of the mouth portion, making it difficult to insert a tool or the like between the outer circumferential surface of the fitting tube and the inner circumferential surface of the mouth portion, and reliably making it difficult to disengage the locking protrusion from the locking recess.

本発明の上記態様によれば、注出筒部材を口部から外しにくくすることができる。 According to the above aspect of the present invention, it is possible to make it difficult for the dispensing tube member to be removed from the mouth portion.

以上説明したように、本実施形態による注出容器１によれば、注出筒部材１３の嵌合筒３１が、口部２１内に嵌合され、口部２１の内周面に、係止凹部２２ａが形成され、嵌合筒３１の外周面に、係止凹部２２ａに係止された係止突部３２が形成されているので、例えば注出筒部材１３と口部２１との間に工具等を差し込みにくくなり、係止突部３２と係止凹部２２ａとの係合を外しにくくすることが可能になり、注出筒部材１３を口部２１から外しにくくすることができる。 As described above, according to the dispensing container 1 of this embodiment, the fitting tube 31 of the dispensing tube member 13 is fitted into the mouth portion 21, the locking recess 22a is formed on the inner peripheral surface of the mouth portion 21, and the locking protrusion 32 that is locked to the locking recess 22a is formed on the outer peripheral surface of the fitting tube 31. Therefore, for example, it becomes difficult to insert a tool or the like between the dispensing tube member 13 and the mouth portion 21, and it becomes possible to make it difficult to disengage the locking protrusion 32 from the locking recess 22a, and it becomes difficult to remove the dispensing tube member 13 from the mouth portion 21.

中栓部材１２に、嵌合筒３１内に挿入され、嵌合筒３１の内周面に当接、若しくは近接した支持壁部３４が設けられているので、嵌合筒３１を支持壁部３４に当接させることで、嵌合筒３１の縮径変形を規制することが可能になり、係止突部３２と係止凹部２２ａとの係合を確実に外しにくくすることができる。 The plug member 12 is provided with a support wall 34 that is inserted into the fitting tube 31 and abuts or is close to the inner peripheral surface of the fitting tube 31. By abutting the fitting tube 31 against the support wall 34, it is possible to restrict the deformation of the fitting tube 31 by reducing its diameter, and it is possible to reliably prevent the engagement between the locking protrusion 32 and the locking recess 22a from coming off.

支持壁部３４の外周面のうち、上端部３４ａが、嵌合筒３１の内周面に当接し、上端部３４ａより下方に位置する下部３４ｂが、嵌合筒３１の内周面から径方向の内側に離れて近接しているので、嵌合筒３１の上端部内に支持壁部３４の上端部３４ａを嵌合して、注出筒部材１３および中栓部材１２を互いに連結した状態で、これらを口部２１に装着する際、嵌合筒３１の係止突部３２が、口部２１の内周面を摺動して係止凹部２２ａに到達するまでの間に、嵌合筒３１の下部を径方向の内側に向けて弾性変形させることが可能になり、注出容器１を容易に組み立てることができる。 Of the outer peripheral surface of the support wall portion 34, the upper end portion 34a abuts against the inner peripheral surface of the fitting tube 31, and the lower portion 34b, which is located below the upper end portion 34a, is close to but away from the inner peripheral surface of the fitting tube 31 in the radially inward direction. Therefore, when the upper end portion 34a of the support wall portion 34 is fitted into the upper end portion of the fitting tube 31 and the spouting tube member 13 and the inner plug member 12 are attached to the mouth portion 21 while being connected to each other, the lower portion of the fitting tube 31 can be elastically deformed radially inward while the locking protrusion 32 of the fitting tube 31 slides along the inner peripheral surface of the mouth portion 21 until it reaches the locking recess 22a, and the spouting container 1 can be easily assembled.

注出筒部材１３に、嵌合筒３１から径方向の外側に向けて突出して、口部２１の上端開口縁を覆い、かつ口部２１の上端開口縁に当接、若しくは近接する被覆壁部３３が設けられているので、嵌合筒３１の外周面と口部２１の内周面との間に工具等を差し込みにくくすることが可能になり、係止突部３２と係止凹部２２ａとの係合を確実に外しにくくすることができる。 The dispensing tube member 13 is provided with a covering wall portion 33 that protrudes radially outward from the fitting tube 31, covers the upper opening edge of the mouth portion 21, and abuts or is close to the upper opening edge of the mouth portion 21. This makes it difficult to insert a tool or the like between the outer peripheral surface of the fitting tube 31 and the inner peripheral surface of the mouth portion 21, and ensures that the engagement between the locking protrusion 32 and the locking recess 22a is difficult to disengage.
