Description

本発明は、練歯磨等を収容する包装チューブに関する。さらに詳しくは、内容物を無駄なく使い切ることのできる包装チューブに関する。   The present invention relates to a packaging tube that contains toothpaste and the like. More specifically, the present invention relates to a packaging tube that can use the contents without waste.

筒状のチューブ本体の一端に開閉キャップを設け、他端を封止して構成される包装チューブは、例えば練歯磨を収容するもの等、従来から広く知られている。   2. Description of the Related Art A packaging tube configured by providing an opening / closing cap at one end of a cylindrical tube body and sealing the other end has been widely known, for example, for housing toothpaste.

そのような包装チューブは内容物を絞り出して使用するものであるが、開閉キャップ近傍の内部空間に最後に残存した内容物を絞り出すのが困難で、ここに残った内容物が無駄に廃棄処分されるという問題がある。   Such a packaging tube is used for squeezing the contents, but it is difficult to squeeze the last remaining contents in the internal space near the opening and closing cap, and the remaining contents are discarded and discarded. There is a problem that.

これを解決するための発明は種々提案されており、例えば、特許文献１および特許文献２がある。   Various inventions for solving this problem have been proposed. For example, there are Patent Document 1 and Patent Document 2.

特許文献１では、チューブ本体の両側に、直線状の凹溝で三辺が構成される三角形領域を２つ対向配置して設けるとともに、両三角形の頂点を別の凹溝で連結している。チューブの周壁が凹溝の位置で簡単に屈曲するので、キャップ近傍の内部空間も小さな力で押し潰すことが可能であり、結果として、内容物を無駄なく絞り出せる。   In Patent Document 1, two triangular regions each having three sides formed by linear concave grooves are provided opposite to each other on both sides of the tube body, and the apexes of both triangles are connected by different concave grooves. Since the peripheral wall of the tube is easily bent at the position of the concave groove, the internal space near the cap can be crushed with a small force, and as a result, the contents can be squeezed without waste.

特許文献２においても、チューブの周壁に、３本の直線状薄肉部を三角形形状に配置して、当該薄肉部においてチューブ周壁が簡単に屈曲するよう構成し、内容物を無駄なく絞り出せるようにしている。
しかしながら、特許文献１および特許文献２のいずれにおいても、最後には、チューブ容器を押し潰して内容物を絞り出すという作業が必要になることに変わりはない。 Also in Patent Document 2, three straight thin portions are arranged in a triangular shape on the peripheral wall of the tube so that the tube peripheral wall can be easily bent at the thin portion so that the contents can be squeezed without waste. ing.
However, in both Patent Document 1 and Patent Document 2, there is no change in the necessity of finally crushing the tube container and squeezing out the contents.

特開２００１−３４１７５８号公報JP 2001-341758 A 実用新案登録第２６０６２１５号Utility model registration No. 2606215

本発明は、上記事情に鑑みて創案されたものであって、内容物を最後まで無駄なく使い切ることができる包装チューブを提供することを目的としている。   The present invention has been made in view of the above circumstances, and an object thereof is to provide a packaging tube that can use the contents without waste until the end.

本発明の包装チューブは、筒状のチューブ本体の一端を塞ぐ封止体に絞出口を設けるとともに、当該絞出口を塞ぐ開閉自在のキャップを備え、他端を封止して構成される。そして、上記封止体をチューブ本体から取外し可能に構成している。   The packaging tube of the present invention is configured by providing a throttle outlet in a sealing body that closes one end of a tubular tube body, and having an openable / closable cap that closes the throttle outlet and sealing the other end. And the said sealing body is comprised so that removal from a tube main body is possible.

上記構成を備えた本発明の包装チューブにおいては、絞出口を備えた封止体がチューブ本体から取外し可能に構成されている。したがって、包装チューブの内容量が少なくなってきて、絞出口から絞り出すことが困難になってきた場合には、当該絞出口を備えた封止体をチューブ本体から取り外すことで、包装チューブの一端を大きく開口させることができる。
このように大きく開いた開口を介して、内容物を最後まで無駄なく使い切ることができる。 In the packaging tube of this invention provided with the said structure, the sealing body provided with the throttle outlet is comprised so that removal from a tube main body is possible. Therefore, when it becomes difficult to squeeze out the squeezing outlet as the inner volume of the wrapping tube decreases, the end of the wrapping tube is removed by removing the sealing body provided with the squeezing outlet from the tube body. It can be opened greatly.
Through such a wide opening, the contents can be used up without waste.

本発明の実施形態を添付の図面を参照して以下に詳細に説明する。
≪第１実施形態≫
図１は、本発明の第１実施形態に係る包装チューブを示す斜視図である。この包装チューブは、チューブ本体１０の一端に設けたキャップ３０の天面を下にして、洗面台等に置いて使用する倒立タイプのものである。
チューブ本体１０の他端１９は、熱融着その他の適宜の方法によりシールされている。 Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
<< First Embodiment >>
FIG. 1 is a perspective view showing a packaging tube according to a first embodiment of the present invention. This packaging tube is an inverted type that is used by placing it on a wash basin or the like with the top surface of the cap 30 provided at one end of the tube body 10 facing down.
The other end 19 of the tube body 10 is sealed by heat sealing or other appropriate methods.

図２（ａ）は、キャップ３０を外した状態を示している。筒状のチューブ本体１０の一端は、絞出口２１を備えた封止体２０により封止されていて、開閉自在のキャップ３０でこれを覆う。
消費者は、チューブ本体１０を握って、絞出口２１から内容物（練歯磨等）を絞り出す。内容物が十分に残存している場合には、簡単に絞り出すことができるが、内容物が少なくなってくると、徐々に絞り出し難くなってくる。 FIG. 2A shows a state where the cap 30 is removed. One end of the tubular tube body 10 is sealed with a sealing body 20 having a throttle outlet 21 and covered with a cap 30 that can be freely opened and closed.
The consumer grasps the tube body 10 and squeezes the contents (toothpaste etc.) from the squeeze outlet 21. If the contents remain sufficiently, it can be easily squeezed out, but as the contents decrease, it becomes difficult to squeeze out gradually.

その場合には、絞出口２１を封止体２０ごと取り外すことで、チューブ本体を大きく開口させる（図２（ｂ））。第１実施形態では、破断除去部４０を介して、封止体２０をチューブ本体１０から取外し可能に構成している。
封止体２０をチューブ本体１０から取り外すと、絞出口２１に比べて非常に大きな開口２３が現れる。この開口２３内に歯ブラシの先端、あるいは指先を挿入して、残存した内容物を無駄なく取り出すことができる。その際に、小さな絞出口から内容物を絞り出すという作業は必要ない。 In that case, the tube main body is greatly opened by removing the throttle port 21 together with the sealing body 20 (FIG. 2B). In the first embodiment, the sealing body 20 is configured to be detachable from the tube main body 10 via the fracture removing portion 40.
When the sealing body 20 is removed from the tube main body 10, a very large opening 23 appears as compared with the throttle outlet 21. By inserting the tip of the toothbrush or the fingertip into the opening 23, the remaining contents can be taken out without waste. At that time, it is not necessary to squeeze the contents from a small squeeze outlet.

図３（ａ）の要部断面図に示したように、破断除去部４０は、全周に渡って延在する薄肉部４３を介して封止体２０に連結された細長い部材であって、摘み部４１を摘んで周方向に引っ張りながら除去することができる。このような構成自体は、「ピルファー」と呼ばれ、一般に知れたものである。   As shown in the cross-sectional view of the main part of FIG. 3A, the fracture removing portion 40 is an elongated member connected to the sealing body 20 through a thin portion 43 extending over the entire circumference, It can be removed while picking the knob 41 and pulling in the circumferential direction. Such a configuration itself is called a “pilfer” and is generally known.

ただし、何らかの方法で封止体２０の周囲を破断し、これにより封止体２０をチューブ本体１０から取り外すことができるものであれば、具体的な構成は、図示したものに限定されない。   However, the specific configuration is not limited to the illustrated configuration as long as the periphery of the sealing body 20 can be broken by some method and the sealing body 20 can be removed from the tube body 10 by this method.

キャップ３０は、チューブ本体１０から封止体２０を取り外す前においても、後においても、チューブ本体１０に係合して絞出口２１（あるいは開口２３）を封止することができる。
すなわち、封止体２０がチューブ本体１０から取り外される前においては、図３（ａ）の要部断面図に示したように、キャップ３０の内面側に設けた弾性突起（第１係合部）３１が絞出口２１に係合することにより、キャップ３０が固定される。
一方、封止体２０がチューブ本体１０から取り外された後においては、図３（ｂ）の要部断面図に示したように、キャップ３０の周壁端部に設けた弾性係合部（第２係合部）３２がチューブ本体１０の端部係合部１０ａと係合することにより、キャップ３０が固定される。 The cap 30 can be engaged with the tube body 10 before and after the sealing body 20 is removed from the tube body 10 to seal the throttle outlet 21 (or the opening 23).
That is, before the sealing body 20 is removed from the tube main body 10, as shown in the cross-sectional view of the main part in FIG. 3A, the elastic protrusion (first engaging portion) provided on the inner surface side of the cap 30. The cap 30 is fixed by engaging 31 with the outlet 21.
On the other hand, after the sealing body 20 is removed from the tube main body 10, as shown in the cross-sectional view of the main part in FIG. The cap 30 is fixed by engaging the engaging portion) 32 with the end engaging portion 10 a of the tube body 10.

≪第２実施形態≫
第１実施形態においては、絞出口２１を備えた封止体２０が一般に「ピルファー」と呼ばれる破断除去部４０を介してチューブ本体１０に取外し可能に連結されていた。
第２実施形態に係る包装チューブでは、封止体をチューブ本体に取外し可能に連結する方法が異なる。第２実施形態では、ネジ係合を利用している。以下に、第１実施形態と異なる点に重点を置いて説明する。 << Second Embodiment >>
In the first embodiment, the sealing body 20 provided with the throttle outlet 21 is detachably connected to the tube main body 10 via a fracture removing portion 40 that is generally called a “pilfer”.
In the packaging tube which concerns on 2nd Embodiment, the method of connecting a sealing body to a tube main body so that removal is possible differs. In the second embodiment, screw engagement is used. The following description will be given with an emphasis on differences from the first embodiment.

絞出口２１を備えた封止体２０’は、その外周部に内ネジ（図示せず）が切られている。一方、チューブ本体１０’の開口端周縁の外表面には外ネジ１５が切られている（図４（ｂ））。これらの内ネジと外ネジとが係合することにより、封止体２０’は、包装チューブ１０’に取外し可能に固定される。
図４（ａ）は、封止体２０’と包装チューブ１０’が連結した状態を、図４（ｂ）は、両者が離れた状態を、それぞれ示している。 An inner thread (not shown) is cut on the outer peripheral portion of the sealing body 20 ′ provided with the throttle outlet 21. On the other hand, an external screw 15 is cut on the outer surface of the peripheral edge of the opening end of the tube body 10 ′ (FIG. 4B). The sealing body 20 ′ is detachably fixed to the packaging tube 10 ′ by the engagement of the inner screw and the outer screw.
FIG. 4A shows a state where the sealing body 20 ′ and the packaging tube 10 ′ are connected, and FIG. 4B shows a state where both are separated.

封止体２０’の外周面２５を多角柱形状としているので、消費者は、この部分を掴んで簡単にネジ係合を利用した係脱作業を行うことができる。   Since the outer peripheral surface 25 of the sealing body 20 ′ has a polygonal column shape, the consumer can easily engage and disengage using the screw engagement by grasping this portion.

封止体２０’をチューブ本体１０’から取り外すと、絞出口２１に比べて非常に大きな開口２３が現れる。この開口２３内に歯ブラシの先端、あるいは指先を挿入して、残存した内容物を無駄なく取り出すことができる。その際に、小さな絞出口から内容物を絞り出すという作業は必要ない。   When the sealing body 20 ′ is removed from the tube body 10 ′, a very large opening 23 appears as compared with the throttle outlet 21. By inserting the tip of the toothbrush or the fingertip into the opening 23, the remaining contents can be taken out without waste. At that time, it is not necessary to squeeze the contents from a small squeeze outlet.

また、第２実施形態では、ネジ係合を利用して封止体２０’をチューブ本体１０’に取外し可能に連結しているので、封止体２０’は、一旦チューブ本体１０’から取り外した後においても、再度、チューブ本体１０’に連結することが可能である。   In the second embodiment, since the sealing body 20 ′ is detachably connected to the tube main body 10 ′ using screw engagement, the sealing body 20 ′ is once removed from the tube main body 10 ′. Later, it is possible to connect to the tube body 10 'again.

キャップ３０’は、第１実施形態と同様に、絞出口２１に係合する弾性突起（係合部）３１を内面側に備えている。キャップ３０’は、ヒンジ連結部２６を介して封止体２０’に連結されているが、第１実施形態におけるキャップ３０と同様に、周壁端部に第２の弾性係合部を設けて、これを利用して封止体２０’と連結するように構成してもよい。   As in the first embodiment, the cap 30 ′ includes an elastic protrusion (engagement portion) 31 that engages with the throttle outlet 21 on the inner surface side. The cap 30 ′ is connected to the sealing body 20 ′ via the hinge connecting portion 26, but like the cap 30 in the first embodiment, a second elastic engagement portion is provided at the peripheral wall end, You may comprise so that it may connect with sealing body 20 'using this.
