特開２００２−３２１７５５号公報JP 2002-321755 A

飲料容器には、持ち運びができるように飲み口に飲料の漏れを防止する漏れ防止機構が設けられていることがあるが、その機構の取外しができないため、部品の交換ができない。さらに、交換可能な部品とする場合には、幼児の誤飲を防止できる構成としなければならない。   The beverage container may be provided with a leakage prevention mechanism for preventing the beverage from leaking at the drinking port so that it can be carried. However, since the mechanism cannot be removed, the parts cannot be replaced. Furthermore, when it is set as a replaceable part, it must be configured to prevent accidental ingestion of infants.

そこで、本発明は携帯時の飲み口の漏れを防止する交換可能な部品を有し、かつその部品の誤飲も防止できる飲料容器を提供することを目的とする。   Then, an object of this invention is to provide the drink container which has the exchangeable part which prevents the leakage of the drinking mouth at the time of carrying, and can also prevent the accidental ingestion of the part.

本発明の飲料容器は、内部に飲料を保持し、飲料が流出する流出部（１５）を有する容器本体（２）と、前記容器本体に対して開閉可能で前記流出部に向かい合う裏面側に取付部（２１）を有する蓋（３）と、前記取付部に固定される固定部（３２）を有し前記蓋の閉時に前記流出部に栓をするパッキン（６）と、前記固定部を前記取付部に固定するパッキン押え部材（７）と、を備えた飲料容器であって、前記パッキン押え部材は、前記取付部に対して着脱可能な着脱位置と前記パッキンを固定する固定位置との間で移動可能で、前記パッキン押え部材及び前記取付部のうち少なくともいずれか一方には、前記パッキン押え部材が前記着脱位置と前記固定位置との間を移動する際に、前記固定位置に存在するときよりも前記固定部の弾性変形量が増加するように前記パッキン押え部材を変位させる凸部（４３ａ）が設けられていることにより上記課題を解決する。   The beverage container according to the present invention has a beverage main body (2) having an outflow portion (15) for holding the beverage therein and through which the beverage flows out, and is attached to the back side facing the outflow portion, which can be opened and closed with respect to the container main body. A lid (3) having a portion (21), a packing (6) having a fixing portion (32) fixed to the mounting portion and plugging the outflow portion when the lid is closed, and the fixing portion A packing presser member (7) that is fixed to the mounting portion, wherein the packing presser member is between a detachable position that is attachable to and detachable from the mounting portion and a fixed position that fixes the packing. When at least one of the packing pressing member and the mounting portion is located at the fixed position when the packing pressing member moves between the attachment / detachment position and the fixed position. Than the elastic deformation of the fixed part To solve the above problem by protrusions amount displacing the gland member to increase (43a) is provided.

本発明の飲料容器によれば、飲料の流出部に対して向かい合う蓋の裏面側に設けられた取付部に、パッキン押え部材によりパッキンが取り付けられる。これにより、蓋を閉めた際に流出部をパッキンで塞ぐことができる。パッキンはパッキン押え部材により固定されるが、凸部が設けられているので、パッキンが弾性変形しないとパッキンの取付け又は取外しができない。凸部がパッキン押え部材及び取付部のうちいずれか一方に設けられていれば、取付部との関係でパッキン押え部材がパッキンを弾性変形させるように変位する。これにより、幼児が容易にパッキンを取り外すことはできない。従って、幼児によるパッキンの誤飲を防ぐができ、かつパッキンを交換することもできる。   According to the beverage container of the present invention, the packing is attached to the attachment portion provided on the back side of the lid facing the beverage outflow portion by the packing pressing member. Thereby, when the lid is closed, the outflow portion can be closed with the packing. Although the packing is fixed by the packing pressing member, since the convex portion is provided, the packing cannot be attached or detached unless the packing is elastically deformed. If a convex part is provided in any one of a packing pressing member and an attaching part, it will displace so that a packing pressing member may elastically deform a packing in relation to an attaching part. Thereby, an infant cannot remove packing easily. Therefore, it is possible to prevent an accidental swallowing of the packing by an infant and to exchange the packing.

本発明の飲料容器の一形態において、前記取付部は円筒形状で、その外周面の一部に突起（２４）を有し、前記パッキン押え部材が、前記固定部を押さえつけながら前記取付部の回りに回転することで、前記パッキン押え部材に設けられた前記凸部が前記突起を回避して前記着脱位置及び前記固定位置の間を移動してもよい。この形態によれば、パッキン押え部材の凸部が取付部の突起を回避するため、パッキンの固定部がパッキン押え部材により押し付けられる。これにより、パッキンが弾性変形されないとパッキン押え部材を着脱位置と固定位置との間で移動させることができないので、幼児による操作を防止して誤飲を防ぐ。   In one form of the beverage container of the present invention, the attachment portion has a cylindrical shape and has a protrusion (24) on a part of the outer peripheral surface thereof, and the packing presser member surrounds the attachment portion while pressing the fixing portion. , The protrusion provided on the packing pressing member may move between the attachment / detachment position and the fixing position while avoiding the protrusion. According to this aspect, since the convex portion of the packing pressing member avoids the protrusion of the mounting portion, the fixing portion of the packing is pressed by the packing pressing member. As a result, since the packing pressing member cannot be moved between the attachment / detachment position and the fixing position unless the packing is elastically deformed, an operation by an infant is prevented to prevent accidental ingestion.

本発明の飲料容器の一形態において、前記固定部の前記パッキン押え部材との接触面には、複数の突出部（３４）が設けられていてもよい。この形態によれば、突出部が弾性変形するのでパッキン押え部材を適切な押込み力で押し付けることができる。突出部の形状や個数を調整することにより、パッキン押え部材の押込み力を幼児には操作不可能な程度に設定することができる。   One form of the drink container of this invention WHEREIN: The some protrusion part (34) may be provided in the contact surface with the said packing pressing member of the said fixing | fixed part. According to this aspect, since the protrusion is elastically deformed, the packing pressing member can be pressed with an appropriate pressing force. By adjusting the shape and number of the projecting portions, the pushing force of the packing pressing member can be set so that it cannot be operated by an infant.

本発明の飲料容器の一形態において、前記容器本体には、飲料を保持するカップ（４）と、前記流出部を有し飲み口が形成されるアダプタ（５）とが設けられ、前記カップに対し前記アダプタが着脱可能であってもよい。この形態によれば、カップとアダプタとが分離するので取り扱いが容易となり、利便性が向上する。   In one form of the beverage container of the present invention, the container body is provided with a cup (4) for holding a beverage and an adapter (5) having the outflow portion and having a drinking mouth, On the other hand, the adapter may be detachable. According to this embodiment, since the cup and the adapter are separated from each other, handling becomes easy, and convenience is improved.

本発明の飲料容器の一形態において、前記アダプタには、コップの縁部の形状を模した飲み口部（１１）が形成されていてもよい。この形態によれば、コップ形状を模した飲み口部が形成されていても、パッキンにより流出部を塞ぐことで飲料の漏れを防止することができる。しかも、パッキンは交換可能なので利便性が向上する。   In one form of the beverage container of the present invention, the adapter may be formed with a drinking mouth part (11) simulating the shape of the edge of the cup. According to this form, even if the drinking mouth part imitating the cup shape is formed, the leakage of the beverage can be prevented by closing the outflow part with the packing. Moreover, since the packing can be exchanged, convenience is improved.

なお、以上の説明では本発明の理解を容易にするために添付図面の参照符号を括弧書きにて付記したが、それにより本発明が図示の形態に限定されるものではない。   In addition, in the above description, in order to make an understanding of this invention easy, the reference sign of the accompanying drawing was attached in parenthesis, but this invention is not limited to the form of illustration by it.

以上、説明したように、本発明の飲料容器においては、飲料の流出部に対して向かい合う蓋の裏面側に設けられた取付部に、パッキン押え部材によりパッキンが取り付けられる。これにより、蓋を閉めた際に流出部をパッキンで塞ぐことができる。パッキンはパッキン押え部材により固定されるが、凸部が設けられているので、パッキンが弾性変形しないとパッキンの取付け又は取外しができない。凸部がパッキン押え部材及び取付部のうちいずれか一方に設けられていれば、取付部との関係でパッキン押え部材がパッキンを弾性変形させるように変位する。これにより、幼児が容易にパッキンを取り外すことはできない。従って、幼児によるパッキンの誤飲を防ぐができ、かつパッキンを交換することもできる。   As described above, in the beverage container of the present invention, the packing is attached to the attachment portion provided on the back side of the lid facing the beverage outflow portion by the packing pressing member. Thereby, when the lid is closed, the outflow portion can be closed with the packing. Although the packing is fixed by the packing pressing member, since the convex portion is provided, the packing cannot be attached or detached unless the packing is elastically deformed. If a convex part is provided in any one of a packing pressing member and an attaching part, it will displace so that a packing pressing member may elastically deform a packing in relation to an attaching part. Thereby, an infant cannot remove packing easily. Therefore, it is possible to prevent an accidental swallowing of the packing by an infant and to exchange the packing.

On the lower surface side of the fixed portion 32, a recess 35 (see FIG. 1) that can be fitted with the protrusion 25 provided on the cap 3 is formed. The protrusion 25 and the recess 35 are fitted together when the packing 6 is attached to the attachment portion 21, thereby preventing the packing 6 from rotating around the attachment portion 21.

図４にパッキン押え部材７の斜視図を示す。パッキン押え部材７は、リング形状で、パッキン６の固定部３２と同様、内周面７ａには取付部２１の小片２４を避けて取付部２１に嵌め込めるように凹部４１が設けられている。また、パッキン押え部材７の外周面７ｂには、キャップ４の取付部２１にパッキン６及びパッキン押え部材７の嵌め込み後、パッキン押え部材７をその軸線方向の回りに回転させるための一対のつまみ４２が対向して設けられている。つまみ４２は、外周面７ｂに突出して設けられ、取付部２１にパッキン押え部材７を取り付けたときに正逆方向に回転操作ができるように構成されている。パッキン押え部材７は、その回転操作時に取付部２１の小片２４がパッキン押え部材７の上面７ｃをスライド可能なように、上面７ｃが軸線方向に後退してパッキン固定部４３を形成している。パッキン固定部４３には、凸部としての押込み部４３ａ及び押え部４３ｂが段差を生じるように設けられている。パッキン固定部４３は、押え部４３ｂに対し押込み部４３ａが凸となるように段差が形成されている。   FIG. 4 is a perspective view of the packing pressing member 7. The packing pressing member 7 has a ring shape and is provided with a recess 41 on the inner peripheral surface 7 a so as to be fitted into the mounting portion 21 while avoiding the small piece 24 of the mounting portion 21, similar to the fixing portion 32 of the packing 6. Further, a pair of knobs 42 for rotating the packing presser member 7 about its axial direction after the packing 6 and the packing presser member 7 are fitted into the mounting portion 21 of the cap 4 on the outer peripheral surface 7b of the packing presser member 7. Are provided opposite to each other. The knob 42 is provided so as to protrude from the outer peripheral surface 7 b, and is configured to be capable of rotating in the forward and reverse directions when the packing presser member 7 is attached to the attachment portion 21. The packing pressing member 7 has a packing fixing portion 43 which is retreated in the axial direction so that the small piece 24 of the mounting portion 21 can slide on the upper surface 7c of the packing pressing member 7 during the rotation operation. The packing fixing portion 43 is provided with a pressing portion 43a and a pressing portion 43b as convex portions so as to form a step. The packing fixing portion 43 is formed with a step so that the pressing portion 43a is convex with respect to the pressing portion 43b.

キャップ３の開閉部２２は、キャップ３の裏面側に設けられ、キャップ３の閉時にアダプタ５の飲み口部１１に引っ掛かって固定されるように構成される。キャップ３の凸部２３は、アダプタ５の支持部１３に嵌め込み可能に形成される。なお、アダプタ５に対してキャップ３を着脱可能となるように構成されていてもよい。   The opening / closing part 22 of the cap 3 is provided on the back side of the cap 3 and is configured to be hooked and fixed to the drinking mouth part 11 of the adapter 5 when the cap 3 is closed. The convex portion 23 of the cap 3 is formed so as to be fitted into the support portion 13 of the adapter 5. Note that the cap 3 may be detachable from the adapter 5.

飲料容器１のパッキン６の取付け手順を説明する。パッキン６は、キャップ３の裏面側に取り付けられる。図５に示すように、パッキン６の固定部３２をキャップ３の取付部２１に嵌める。このとき、固定部３２は、取付部２１の小片２４と固定部３２の凹部３３との位置が一致するように取付部２１に嵌められ、それと同時にキャップ３の突起２５にパッキン６の凹部３５が嵌め込まれる。次に図６に示すようにして、パッキン６が取り付けられた取付部２１に対してパッキン押え部材７をさらに嵌める。パッキン押え部材７もパッキン６と同様、小片２４とパッキン押え部材７の凹部４１との位置が一致するように取付部２１に嵌められる。パッキン押え部材７のこの状態の位置を着脱位置と呼ぶ。   A procedure for attaching the packing 6 of the beverage container 1 will be described. The packing 6 is attached to the back side of the cap 3. As shown in FIG. 5, the fixing portion 32 of the packing 6 is fitted into the attachment portion 21 of the cap 3. At this time, the fixing portion 32 is fitted into the mounting portion 21 so that the position of the small piece 24 of the mounting portion 21 and the concave portion 33 of the fixing portion 32 coincide with each other, and at the same time, the concave portion 35 of the packing 6 is formed on the protrusion 25 of the cap 3. It is inserted. Next, as shown in FIG. 6, the packing pressing member 7 is further fitted to the mounting portion 21 to which the packing 6 is mounted. Similarly to the packing 6, the packing pressing member 7 is also fitted to the mounting portion 21 so that the positions of the small piece 24 and the concave portion 41 of the packing pressing member 7 coincide. The position of the packing pressing member 7 in this state is referred to as an attaching / detaching position.

そして、パッキン押え部材７を押し込みながら右回りに回す（図７）。このとき、パッキン押え部材７が押し付けられることにより、パッキン６が弾性変形する。小片２４が押込み部４３ａの上面を移動することにより、固定部３２の弾性変形量が増加するようにパッキン押え部材７を変位させる。特に、固定部３２の上面３２ｂに設けられた突出部３４により、パッキン６の弾性変形を促し、適切な押込み力でパッキン押え部材７を回転させることができる。突出部３４の高さや面積、個数を調整することで、幼児には操作不可能な固さにできる。そのまま、パッキン押え部材７を小片２４が押え部４３ｂに位置するまで回転させる（図８）。パッキン６の復元力によりパッキン押え部材７は小片２４に押し付けられ、押え部４３ｂに小片２４が嵌まり込む固定位置でパッキン押え部材７が回転不可能な状態で固定される。これにより、パッキン６の取付けが終了する。パッキン６の取外し手順は、取付けと逆の手順により行われる。パッキン押え部材７は、押込み部４３ａにより、固定位置に存在するときよりもパッキン６の固定部３２を弾性変形させないと固定位置と着脱位置との間で移動させることができない。従って、パッキン押え部材７を押し込んで回転させるという二段階操作により、幼児によるパッキン６及びパッキン押え部材７の取外しを防ぎ、誤飲を防止する。   Then, the packing pressing member 7 is rotated clockwise while being pushed in (FIG. 7). At this time, the packing 6 is elastically deformed by pressing the packing pressing member 7. When the small piece 24 moves on the upper surface of the pressing portion 43a, the packing pressing member 7 is displaced so that the elastic deformation amount of the fixing portion 32 increases. In particular, the protruding portion 34 provided on the upper surface 32b of the fixed portion 32 can accelerate the elastic deformation of the packing 6 and rotate the packing pressing member 7 with an appropriate pressing force. By adjusting the height, area, and number of the protrusions 34, it is possible to make the protrusions difficult to operate. As it is, the packing pressing member 7 is rotated until the small piece 24 is positioned at the pressing portion 43b (FIG. 8). The packing pressing member 7 is pressed against the small piece 24 by the restoring force of the packing 6, and the packing pressing member 7 is fixed in a non-rotatable state at a fixed position where the small piece 24 fits into the pressing portion 43b. Thereby, the attachment of the packing 6 is completed. The procedure for removing the packing 6 is performed in the reverse order of the attachment. The packing pressing member 7 cannot be moved between the fixed position and the attaching / detaching position unless the fixing portion 32 of the packing 6 is elastically deformed by the pressing portion 43a as compared with the case where the packing pressing member 7 exists at the fixing position. Therefore, the two-step operation of pushing and rotating the packing presser member 7 prevents the infant from removing the packing 6 and the packing presser member 7 and prevents accidental ingestion.

本発明は、上述した形態に限定されることなく、種々の形態にて実施することができる。本形態では、押込み部４３ａがパッキン押え部材７に設けられている例で説明したがこれに限られない。例えば、取付部２１に設けられていてもよい。パッキン押え部材７又は取付部２１のいずれか一方に押込み部４３ａが形成されていれば、パッキン押え部材７の移動時にパッキン抑え部材が固定部３２を弾性変形させるように変位することができる。一例として、取付部２１の小片２４のパッキン押え部材７との接触面に、凸部を形成し、その凸部が固定位置でパッキン押え部材７と嵌りあうように、取付部２１及びパッキン押え部材７を構成してもよい。この小片２４に形成された凸部を中央が凸となるような傾斜面、つまり断面がＶ字形状あるいはＵ字形状となるように形成すれば、パッキン押え部材７は固定位置及び着脱位置の間をスムーズに移動できる。   The present invention is not limited to the above-described form and can be implemented in various forms. In the present embodiment, the example in which the pressing portion 43a is provided in the packing pressing member 7 has been described, but the present invention is not limited thereto. For example, you may be provided in the attaching part 21. FIG. If the pressing portion 43 a is formed on either the packing pressing member 7 or the attachment portion 21, the packing pressing member 7 can be displaced so as to elastically deform the fixing portion 32 when the packing pressing member 7 moves. As an example, a convex portion is formed on the contact surface of the small piece 24 of the mounting portion 21 with the packing pressing member 7, and the mounting portion 21 and the packing pressing member are fitted with the packing pressing member 7 at a fixed position. 7 may be configured. If the convex portion formed on the small piece 24 is formed to have an inclined surface with a convex center, that is, a cross section having a V shape or U shape, the packing presser member 7 is located between the fixed position and the detachable position. Can move smoothly.

本形態では、パッキン６が弾性体で一体成形された例で説明したがこれに限られず、パッキン６の凸部３１と固定部３２とが別個の素材で形成されていてもよい。本形態では、コップタイプのアダプタ５にパッキン６を取り付ける例を説明したが、これに限られず、スパウトやストロー等からの飲料の流出を防ぐために用いてもよい。パッキン６の凸部３１の形状は、飲み口側の形状に合わせて適宜変更してもよい。容器本体２にカップ４及びアダプタ５が設けられている例で説明したがこれに限られず、例えば、カップ４に流出部１５が設けられていてもよい。つまり、カップ４とアダプタ５とが一体成形されていてもよく、このような場合においても流出部１５を塞ぐ際に本発明のパッキン６及びパッキン押え部材７を適用することができる。小片２４の個数についても２つ設けられた例に限られず、適宜の個数設けてもよい。   In this embodiment, the example in which the packing 6 is integrally formed of an elastic body has been described. However, the present invention is not limited to this, and the convex portion 31 and the fixing portion 32 of the packing 6 may be formed of different materials. In this embodiment, the example in which the packing 6 is attached to the cup-type adapter 5 has been described. However, the present invention is not limited to this, and the cup 6 may be used to prevent a beverage from flowing out from a spout or a straw. The shape of the convex portion 31 of the packing 6 may be appropriately changed according to the shape of the drinking mouth side. Although the example in which the cup 4 and the adapter 5 are provided in the container body 2 has been described, the present invention is not limited to this. For example, the outflow part 15 may be provided in the cup 4. That is, the cup 4 and the adapter 5 may be integrally formed. Even in such a case, the packing 6 and the packing pressing member 7 of the present invention can be applied when closing the outflow portion 15.
