On the other hand, in the present embodiment, a covering wall 70 that covers the outside air introduction hole 5d is provided on the outer peripheral surface of the discharge cylinder portion 51 so as to protrude outward in the radial direction. The covering wall 70 of the present embodiment is formed in an annular plate shape and is formed integrally with the discharge cylinder portion 51.
Here, in this embodiment, the overcap 6 has a lower cylindrical portion 6a whose lower end portion is externally fitted to the peripheral wall portion 50b of the discharge cap body 5, and an annular shape projecting radially inward from the upper end portion of the lower cylindrical portion 6a.

A vertical space is formed between the connecting plate 6b of the overcap 6 and the top wall portion 50a of the discharge cap body 5, and the covering wall 70 is between the connecting plate 6b and the top wall portion 50a. It extends along the connecting plate 6b and the top wall 50a. The covering wall 70 is elastically displaceable in the vertical direction.

被覆壁70は、吐出筒部51の外周面の下端部から径方向の外側に向けて、吐出キャップ本体5の天壁部50aの径方向外側端部の上方まで延び、さらに詳しくは、被覆壁70の径方向外側端部は、径方向外側に向かうに従い次第に下方に湾曲して延びている。   The covering wall 70 extends from the lower end portion of the outer peripheral surface of the discharge cylinder portion 51 to the outside in the radial direction and above the radially outer end portion of the top wall portion 50a of the discharge cap body 5, and more specifically, the covering wall.

本実施形態の被覆壁70は、図1中の二点鎖線で示す状態のように成形直後では、吐出筒部51の先端側に向けて湾曲する状態となっているが、被覆壁70は、オーバーキャップ6が吐出キャップ本体5に装着され、オーバーキャップ6の連結板6bによって下方に向けて湾曲された状態とされることで、径方向に沿って延びるくせがつけられ、オーバーキャップ6が吐出キャップ本体5から取り外された場合であっても、成形直後のように、吐出筒部51の先端側に向けて湾曲する状態に復帰しなくなっている。
なお、本実施形態では、被覆壁70がオーバーキャップ6の装着時に連結板6bによって下方に向けて湾曲された状態とされるが、図1中の二点鎖線で示す被覆壁70の成形直後の状態において、成形時の余熱や成形後の被覆壁70に熱を加えること等によって、被覆壁70を径方向に沿って延びる状態や下方に湾曲された状態に塑性変形させてもよい。

Even when the cap body 5 is removed, it does not return to the state of being curved toward the tip end side of the discharge cylinder portion 51 just after molding.
In the present embodiment, the covering wall 70 is bent downward by the connecting plate 6b when the overcap 6 is mounted, but immediately after the forming of the covering wall 70 indicated by the two-dot chain line in FIG. In the state, the covering wall 70 may be plastically deformed into a state of extending in the radial direction or a state of being curved downward by, for example, applying heat to the covering wall 70 after molding or after forming.

次に、図4を用いて、以上説明した本実施形態による吐出容器1の典型的な使用方法について説明する。   Next, a typical method of using the discharge container 1 according to the present embodiment described above will be described with reference to FIG.

容器本体4の内容器2に収容された内容物を吐出させるとき、本実施形態の吐出容器1では、まずオーバーキャップ6を開け、例えば、吐出口13が下方に向くような吐出姿勢とした状態で容器本体4の外容器3をスクイズ変形(弾性変形)させる。
これにより、内容器2が外容器3とともに変形して減容される。そして、この減容変形に伴い内容器2の内圧が上昇し、この内圧の上昇に伴い、吐出弁36の連結部41が弾性変形して板体40が閉塞板部9の支持板部91の膨出部91xから吐出口13側へ向けて離間し、連通孔9fが開放され、連絡路Xと連通する。これにより、内容器2の内部と吐出口13とが連通し、内容器2に収容された内容物が連絡路Xを通って吐出口13から吐出される。ここで、押圧体60は、板体40の変位に伴って吐出口13側へ弾性変位される。なお、連絡路Xに流入した内容物等は、板体40の径方向の外側を通って吐出口13側へ流れる。
When discharging the contents stored in the inner container 2 of the container body 4, in the discharge container 1 of the present embodiment, the overcap 6 is first opened and, for example, the discharge posture is such that the discharge port 13 faces downward. Thus, the outer container 3 of the container body 4 is squeezed (elastically deformed).
Thereby, the inner container 2 is deformed together with the outer container 3 to reduce the volume. Then, the internal pressure of the inner container 2 rises along with this volume reduction deformation, and with this rise in internal pressure, the connecting portion 41 of the discharge valve 36 is elastically deformed, and the plate body 40 of the support plate portion 91 of the closing plate portion 9 is deformed. Separating from the bulging portion 91x toward the discharge port 13 side, the communication hole 9f is opened and communicates with the communication path X. Thereby, the inside of the inner container 2 and the discharge port 13 communicate with each other, and the contents stored in the inner container 2 are discharged from the discharge port 13 through the communication path X. Here, the pressing body 60 is elastically displaced toward the discharge port 13 as the plate body 40 is displaced. The contents and the like that have flowed into the communication path X flow toward the discharge port 13 through the outer side of the plate body 40 in the radial direction.

また、このとき、外容器3がスクイズ変形(弾性変形)されることで、内容器2と外容器3との間は正圧になり、内容器2と外容器3との間にある空気が、吸気孔7cから吸気通路Yを通って外気導入孔5dから外部に流れようとする。ここで、吸気通路Yの途中にある弁座筒部91bに着座した空気弁45は圧力を受けて外気導入孔5d側へ移動し、外気導入孔5dを閉じる。これにより、外気導入孔5dからの排出を規制された空気は、補助孔95を通って連絡路Xへ流れる。これにより、この吐出容器1では、連絡路Xで気液混合がなされ、吐出筒部51内に設けられた発泡部材100により気液混合体が好適に発泡される。   At this time, the outer container 3 is squeezed (elastically deformed) so that a positive pressure is applied between the inner container 2 and the outer container 3, and the air between the inner container 2 and the outer container 3 is Then, the air tends to flow from the outside air introduction hole 5d through the intake passage Y through the intake hole 7c. Here, the air valve 45 seated on the valve seat tube portion 91b in the middle of the intake passage Y receives pressure and moves to the outside air introduction hole 5d side, and closes the outside air introduction hole 5d. As a result, the air whose discharge from the outside air introduction hole 5 d is restricted flows through the auxiliary hole 95 to the communication path X. Thus, in this discharge container 1, gas-liquid mixing is performed in the communication path X, and the gas-liquid mixture is suitably foamed by the foaming member 100 provided in the discharge cylinder portion 51.

その後、内容器2の内圧が低下すると、連結部41が弾性復元力により復元変形して板体40により連通孔9fが閉じられるとともに、連絡路Xと内容器2の内部との連通が遮断されて内容器2が密封される。このとき、押圧体60は、弾性復元力により復元変形して板体40を押圧した状態に復帰し、板体40の閉じ状態を保持する。
また、さらに上述したスクイズ変形が解除されると、外容器3は復元変形しようとする。このとき、外容器3と内容器2との間に発生した負圧が吸気孔7cを通して空気弁45に作用することにより、この空気弁45が吸気孔7c側へ向けて開いて吸気孔7cと外部とが連通され、外気が吸気通路Yを通して吸気孔7cから外容器3と内容器2との間に吸入される。そして、内容器2の減容形状が保持される。
Thereafter, when the internal pressure of the inner container 2 decreases, the connecting portion 41 is restored and deformed by the elastic restoring force, the communication hole 9f is closed by the plate body 40, and the communication between the communication path X and the inside of the inner container 2 is blocked. The inner container 2 is sealed. At this time, the pressing body 60 is restored and deformed by the elastic restoring force to return to the state where the plate body 40 is pressed, and the closed state of the plate body 40 is maintained.
Further, when the above-described squeeze deformation is released, the outer container 3 tries to restore and deform. At this time, the negative pressure generated between the outer container 3 and the inner container 2 acts on the air valve 45 through the intake hole 7c, so that the air valve 45 opens toward the intake hole 7c and the intake hole 7c The outside communicates with the outside, and the outside air is sucked between the outer container 3 and the inner container 2 through the intake passage Y through the intake hole 7c. And the volume reduction shape of the inner container 2 is hold | maintained.

この状態から、再び容器本体4の外容器3をスクイズ変形させると、空気弁45は外気導入孔5d側へ移動して外気導入孔5dを閉じる。そして、外容器3と内容器2との間の内圧が上昇し、この内圧の上昇によって内容器2が減容変形される。内容器2が減容変形されることにより、上述同様に内容物が吐出される。このように、スクイズ変形された外容器3が復元変形しても、内容器2は内容物の減少とともに減容されていき、しかも内容器2の内部に外気(内容物と一緒に封入された外気は除く)が流入することが防止されている。これにより、内容物の劣化が防止されて、保存性が高められている。
なお、吐出後は、オーバーキャップ6を吐出キャップ24に装着する。
When the outer container 3 of the container body 4 is squeezed again from this state, the air valve 45 moves to the outside air introduction hole 5d side and closes the outside air introduction hole 5d. Then, the internal pressure between the outer container 3 and the inner container 2 rises, and the inner container 2 is deformed and deformed by the increase in the internal pressure. By reducing the volume of the inner container 2, the contents are discharged in the same manner as described above. As described above, even if the squeezed deformed outer container 3 is restored and deformed, the inner container 2 is reduced in volume as the contents decrease, and the outside air (enclosed together with the contents) is contained inside the inner container 2. (Except outside air) is prevented from flowing in. Thereby, deterioration of the content is prevented and the preservability is improved.
Note that the overcap 6 is attached to the ejection cap 24 after ejection.

ここで、本実施形態の吐出容器1では、吐出筒部51の外周面に、外気導入孔5dを覆う被覆壁70が径方向の外側に向けて突設されているため、吐出口13から内容物を吐出した後に、仮に、吐出口13に内容物等が残存した場合であっても、被覆壁70が、吐出キャップ本体5の外側における吐出口13と外気導入孔5dとの間に位置して、吐出口13に残存した内容物等が吐出筒部51の外周面をつたって外気導入孔5dに進入しようとするのをせき止める。   Here, in the discharge container 1 of the present embodiment, since the covering wall 70 covering the outside air introduction hole 5d is provided on the outer peripheral surface of the discharge cylinder portion 51 toward the outer side in the radial direction, the content from the discharge port 13 Even if the contents remain at the discharge port 13 after discharging the object, the covering wall 70 is located between the discharge port 13 and the outside air introduction hole 5d outside the discharge cap body 5. Thus, the contents remaining in the discharge port 13 are blocked from entering the outside air introduction hole 5d through the outer peripheral surface of the discharge cylinder portion 51.

以上に記載したように、本実施形態の吐出容器1によれば、吐出筒部51の先端の吐出口13に付着した内容物等が吐出筒部51の外周面をつたって外気導入孔5d側に流れようとしたときに、内容物等が被覆壁70によってせき止められる。これにより外気導入孔5dに内容物等が進入してしまうのを防止できる。   As described above, according to the discharge container 1 of the present embodiment, the contents and the like attached to the discharge port 13 at the tip of the discharge cylinder portion 51 pass through the outer peripheral surface of the discharge cylinder portion 51 and are on the outside air introduction hole 5d side.

A double container in which the outer peripheral surface and the inner peripheral surface of the outer container 3 are formed separately may be used.

また、上記実施形態では、吐出容器1が泡吐出容器である例を説明したが、発泡部材100及び補助孔95を備えず、内容物と気体とを気液混合させない吐出容器であっても構わない。   Moreover, although the said embodiment demonstrated the example in which the discharge container 1 is a foam discharge container, it may not be provided with the foaming member 100 and the auxiliary hole 95, and may be a discharge container which does not gas-liquid mix the contents and gas. Absent.

また、上記実施形態では、吐出キャップ24の吐出キャップ本体5の雌ねじ部5cが、容器本体4の口部4aの雄ねじ部7bに螺着されることとしたが、これに限定されるものではない。すなわち、雌ねじ部5c及び雄ねじ部7bを用いる代わりに、例えば容器本体4の口部4aと吐出キャップ本体5とにそれぞれ嵌合凸部を形成してこれらをアンダーカット嵌合させることにより、吐出キャップ24を口部4aに装着することとしてもよい。   Moreover, in the said embodiment, although the internal thread part 5c of the discharge cap main body 5 of the discharge cap 24 was screwed by the external thread part 7b of the opening | mouth part 4a of the container main body 4, it is not limited to this. . That is, instead of using the female screw portion 5c and the male screw portion 7b, for example, by forming fitting protrusions on the mouth portion 4a of the container body 4 and the discharge cap body 5 and fitting them undercut, 24 may be attached to the mouth 4a.

また、上述した閉塞板部9は、基板部90と支持板部91とを備える構成としたが、一部材で構成してもよい。   Moreover, although the closing plate part 9 mentioned above was set as the structure provided with the board | substrate part 90 and the support plate part 91, you may comprise with one member.

また、上記実施形態では、吐出弁36が、連通孔9f及び補助孔95と連絡路Xとを連通及び遮断する弁であるが、連通孔9fと補助孔95とがそれぞれ別の弁で開閉される構成であってもよい。
また、上記実施形態の被覆壁70が環板状に形成され、吐出筒部51と一体に形成されるとしたが、外気導入孔5dの形成位置に応じて、被覆壁70は周方向に間隔をあけて複数形成されていてもよい。また被覆壁70は、吐出筒部51と一体に形成されることなく、別体で吐出キャップ24に設けられてもよい。
また、被覆壁70が環板状に形成しつつ、被覆壁70において、径方向外側端部から内側へ延びるスリットを形成する等して、オーバーキャップ6が吐出キャップ24に装着された際に、被覆壁70が好適にオーバーキャップ6と吐出キャップ24との間に収まるようにしてもよい。
また、上記実施形態では、被覆壁70が径方向に沿って延び、その径方向外側端部が径方向外側に向かうに従い次第に下方に湾曲して延びる例を説明したが、被覆壁70は、外気導入孔5dを覆う形状であればよく、例えば、径方向外側に向かうに従い上方に湾曲して延びる形状や、径方向外側に延びるに従い上方または下方に向けて直線的に傾斜して延びる形状でもよい。
さらに、上記実施形態では、被覆壁70は全体として、外気導入孔5dが形成された天壁部50aと上下方向で離間する態様であるが、被覆壁70は、その径方向外側端部が、天壁部50aに接触又は近接するものであってもよい。この場合には、より確実に、外気導入孔5dに内容物等が進入するのを抑制できる。
In the above embodiment, the discharge valve 36 is a valve that communicates and blocks the communication hole 9f and the auxiliary hole 95 and the communication path X. However, the communication hole 9f and the auxiliary hole 95 are opened and closed by separate valves. It may be a configuration.
Moreover, although the covering wall 70 of the said embodiment was formed in the annular plate shape and formed integrally with the discharge cylinder part 51, according to the formation position of the external air introduction hole 5d, the covering wall 70 is circumferentially spaced. A plurality may be formed with a gap. The covering wall 70 may be provided separately from the discharge cap 24 without being formed integrally with the discharge cylinder portion 51.
Further, when the overcap 6 is attached to the discharge cap 24 by forming a slit extending inward from the radially outer end portion in the covering wall 70 while the covering wall 70 is formed in an annular plate shape, The covering wall 70 may be preferably fitted between the overcap 6 and the discharge cap 24.
Further, in the above-described embodiment, an example has been described in which the covering wall 70 extends along the radial direction and the radially outer end thereof extends and curves downward downward as it goes outward in the radial direction. The shape may be any shape as long as it covers the introduction hole 5d. For example, the shape may be curved and extended upward as it goes radially outward, or may be linearly inclined and extended upward or downward as it extends radially outward. .
Furthermore, in the said embodiment, although the covering wall 70 is the aspect separated in the up-down direction from the top wall part 50a in which the external air introduction hole 5d was formed as a whole, the covering wall 70 has the radial direction outer side edge part, It may be in contact with or close to the top wall 50a. In this case, it is possible to more reliably prevent the contents and the like from entering the outside air introduction hole 5d.
