図５は、チャック部の１例を示す断面図である。図５を参照してチャック部５の構成について説明する。定量注出部２と内容物収容部４が連通部３を介して連通し、連通部３に
チャック部５が形成されている。チャック部５は、雄型シール部２３と雌型シール部２４とを備えており、雄型シール部２３は、雄型を構成する雄型シート２３ｃの背面と第１シート２１の内面とが互いにシールされて形成され、雌型シール部２４は、雌型を構成する雌型シート２４ｃの背面と第２シートの内面とが互いにシールされて形成されている。
FIG. 5 is a cross-sectional view showing one example of the chuck portion. The configuration of the chuck portion 5 will be described with reference to FIG. A quantitative dispensing part 2 and a content storage part 4 communicate with each other through a communicating part 3 , and a chuck part 5 is formed in the communicating part 3 . The chuck portion 5 includes a male seal portion 23 and a female seal portion 24. The male seal portion 23 is configured such that the rear surface of the male sheet 23c constituting the male mold and the inner surface of the first sheet 21 are mutually connected. The female seal portion 24 is formed by sealing the back surface of the female mold sheet 24c and the inner surface of the second sheet, which constitute the female mold, to each other.
図５に示すように、チャック部５は、雌雄咬合型のチャックであって、雌型シール部２４と雄型シール部２３によって構成されている。雌型シール部２４は、雄型シール部２３を挿入した場合に、雄型部分の上側と下側を挟むようになっている。雌型シール部２４は、内側に向かって突出する雌上側突出部２４ａと雌下側突出部２４ｂを備えている。雄型シール部２３は、その上側に沿って雄上側突出部２３ａ、その下側に沿って雄下側突出部２３ｂがそれぞれ突出する形になっている。ここで、チャック部５に対し、上側とは定量注出部側を指し、下側とは内容物収容部側を指す。 As shown in FIG. 5 , the chuck portion 5 is a male-female interlocking chuck, and is composed of a female seal portion 24 and a male seal portion 23 . The female seal portion 24 sandwiches the upper and lower sides of the male portion when the male seal portion 23 is inserted. The female seal portion 24 includes a female upper protrusion 24a and a female lower protrusion 24b that protrude inward. The male seal portion 23 has a male upper projecting portion 23a projecting along its upper side and a male lower projecting portion 23b projecting along its lower side. Here, with respect to the chuck part 5, the upper side refers to the side of the fixed quantity dispensing part, and the lower side refers to the side of the content storage part.
チャック部５の定量注出部側の嵌合強度を、内容物収容部側の嵌合強度より強めるために、図５に示すように、雄上側突出部２３ａと雄下側突出部２３ｂの断面のそれぞれの先端付近の形状を異なるようにした。すなわち、雄上側突出部２３ａの先端部は、根元方向に折り返すフック状となっているが、雄下側突出部２３ｂの先端部は、折り返し部分がなく、単に山形の外側に向かった出っ張りがあるだけである。このようにすれば、雄下側突出部２３ｂと雌下側突出部２４ｂとの引っかかり具合が浅くなるので、内容物収容側からのチャック部５の咬合解除は、弱い力でなされることとなる。それに比較し、反対側の、雄上側突出部２３ａと雌上側突出部２４ａとの引っかかり具合は深く、定量抽出部側からのチャック部５の咬合解除にはより強い力が必要となる。従って、内容物収容側からのチャック部５は開きやすく、定量抽出部側からのチャック部５は開きにくいこととなる。 In order to increase the fitting strength of the quantitative dispensing portion side of the chuck portion 5 more than the fitting strength of the contents accommodating portion side, as shown in FIG. The shape near the tip of each was made different. That is, the tip of the upper male protrusion 23a has a hook shape that is folded back toward the base, but the tip of the lower male protrusion 23b does not have a folded portion, and has a simple outward protrusion in a chevron shape. Only. In this way, the degree of hooking between the male lower projecting portion 23b and the female lower projecting portion 24b becomes shallow, so that the engagement of the chuck portion 5 from the content accommodation side can be released with a weak force. . In comparison, the engagement between the male upper protrusion 23a and the female upper protrusion 24a on the opposite side is deep, and a stronger force is required to release the engagement of the chuck part 5 from the quantitative extraction part side. Therefore, it is easy to open the chuck part 5 from the content accommodation side, and it is difficult to open the chuck part 5 from the quantitative extraction part side.
チャック部５の定量抽出部側の嵌合強度を、内容物収容部側の嵌合強度より強める方法
として、雄上側突出部２３ａと雄下側突出部２３ｂの断面のそれぞれの先端付近の形状を異なるようにしたが、他の例として、雌上側突出部２４ａと雌下側突出部２４ｂの形状を異なるようにしても良い。図６に示すように、雌下側突出部２４ｂの断面形状を折り返さずストレートな形状にすれば、雄下側突出部２３ｂと雌下側突出部２４ｂとの引っかかり具合が浅くなるので、チャック部５の咬合解除は、弱い力でなされることとなり、前記の例と同様の結果が得られる。
As a method for increasing the fitting strength of the chuck portion 5 on the side of the quantitative extraction portion more than the fitting strength on the side of the contents accommodating portion, the shapes near the tips of the cross sections of the upper male projecting portion 23a and the lower male projecting portion 23b are changed. Although they are made different, as another example, the shapes of the upper female protruding portion 24a and the lower female protruding portion 24b may be different. As shown in FIG. 6, if the female lower projecting portion 24b has a straight cross-sectional shape instead of being folded back, the degree of engagement between the male lower projecting portion 23b and the female lower projecting portion 24b becomes shallow, so that the chuck portion The unoccclusion of 5 will be done with a weaker force, with similar results to the previous example.
次に、このパウチ２０を使用して、一定量の内容物を定量注出して取り出す場合について説明する。パウチ２０は、上部から順に、注出口部１、定量注出部２、連通部３、内容物収容部４に分かれており、連通部３には、チャック部５が形成されている。初期状態では、連通部３に形成されたチャック部５は閉じられていて、内容物を内容物収容部４に封止している。ここで図２のように、このパウチ全体を倒立させると、内容物が連通部３及び定量注出部２のほうに移動するが、内容物の内圧によってチャック部５の咬合解除が起こり、チャック部５は開き、内容物はさらに定量注出部２へと移動する。 Next, the case of using this pouch 20 to dispense and take out a fixed amount of contents will be described. The pouch 20 is divided into, in order from the top, a spout portion 1, a fixed quantity spout portion 2, a communication portion 3, and a content storage portion 4. A chuck portion 5 is formed in the communication portion 3. In the initial state, the chuck portion 5 formed in the communicating portion 3 is closed to seal the content in the content accommodating portion 4 . Here, as shown in FIG. 2, when the entire pouch is turned upside down, the contents move toward the communication part 3 and the fixed-quantity dispensing part 2, but the internal pressure of the contents causes the chuck part 5 to be disengaged and the chuck is released. The part 5 opens and the contents move further to the metered dispensing part 2 .
定量注出部２が内容物で満たされた後、チャック部５を閉じてから、図３に示すように、
正立に戻した場合、チャック部５には、定量注出部２内の内容物の内圧がかかるが、咬合状態を保ち続けるので、チャック部５の咬合解除は起らず、定量注出部２の内容物は定量のまま保持される。このように内容物を定量注出した後、図４に示すように、倒立させて注出口部１の注出口１２のキャップ１１を外すと、内容物を容易に取り出すことができる。
このように、本発明のパウチでは、パウチを単に倒立、正立させる簡単な操作によって、一定量の内容物を精度良く容易に取り出すことが可能となる。また、内容物に手を触れずに手を汚すことなく、一定量の内容物を精度良く取り出すことができる。
After the fixed quantity dispensing part 2 is filled with the contents, after closing the chuck part 5, as shown in FIG.
When the chuck portion 5 is returned to the upright position, the internal pressure of the contents in the quantitative dispensing portion 2 is applied to the chuck portion 5, but the occlusion state is maintained, so the chuck portion 5 is not released from the occlusion, and the quantitative dispensing portion is kept. The contents of 2 are kept constant. After pouring out a certain amount of the contents in this way, as shown in FIG. 4, the contents can be easily taken out by turning upside down and removing the cap 11 of the spout 12 of the spout part 1 .
Thus, with the pouch of the present invention, it is possible to accurately and easily take out a certain amount of contents by simply turning the pouch upside down or upright. In addition, a certain amount of contents can be taken out with high accuracy without touching the contents or getting the hands dirty.
