。To specifically explain one embodiment of the present invention with reference to the drawings, the first embodiment is as follows.
In the figures, A is the tube neck, 1 is the valve body, and the outer peripheral surface of the body 2 has four tall vertical ribs 3 protruding in a cross shape. A double-port airtight valve 4 is attached to the upper end of the body 2, and removal prevention projections 5 are provided at the lower ends of corresponding two of the vertical ribs 3.

次に６は押出チューブ本体であって、その注出ロアの内
底部には前記弁体１を強制的に嵌入し得る孔８を有する
弁座９が取付けられている。Next, 6 is an extruded tube main body, and a valve seat 9 having a hole 8 into which the valve body 1 can be forcefully inserted is attached to the inner bottom of the dispensing lower part.

更に１０は前記弁体１の底面よりチューブ首部Ａの肩部

に形成されている。Further, reference numeral 10 denotes two pairs of bridges extending from the bottom surface of the valve body 1 to the inner surface of the shoulder of the tube neck A, thereby holding the valve body 1 on the inner surface of the shoulder of the tube neck A and integrally holding the valve body 1 on the inner surface of the shoulder of the tube neck A. It is formed.

することが出来る。When assembling and using the tube according to the present invention, as shown in FIG. When A and the tube body 6 are glued together and the tube body 6 is pressed with the contents filled and the tube body 6 bent backward, the valve body 1 will rise due to the internal pressure and a gap will be created between the airtight valve 4 and the valve seat 9. A gap between the ribs 3 of the body 2 of the body 1 and the contents stored in the tube can be taken out from the pouring lower through this gap,
Next, when the tube 6 is released, the elasticity of the bridge 10 causes the valve body 1 to descend and the airtight valve 4 to come into close contact with the valve seat 9, thereby completely preventing outside air from entering the tube. .

上記実施例は弁座９を注出ロアの底部に構成したが、第
５図に示す如く注出ロアの上端に持って来ることも当然
可能である。In the above embodiment, the valve seat 9 is arranged at the bottom of the pouring lower, but it is naturally possible to place it at the upper end of the pouring lower as shown in FIG.

首部と組立てる工程が不要となる等の特徴も有している
。As mentioned above, the extruded tube according to the present invention has a valve body integrally connected to the inside of the tube neck via a bridge, so that by attaching this to the valve seat, stored items can be extruded and outside air can be re-introduced. can be reliably prevented,
In addition, the body is provided with a vertical rib with a diameter that corresponds to the hole in the valve seat, which prevents the valve body from rattling, and the lower end of the body has a protrusion to prevent removal. This protrusion prevents the valve body from being pulled out of the valve seat unnecessarily.Furthermore, since the bridge is attached to the bottom of the valve body, it supports the valve body vertically from the lower end and prevents the valve body from unnecessarily pulling out from the valve seat. In addition to being able to move the body up and down vertically, the tube of this invention completely prevents air from entering the tube, preventing stored items from drying out, discoloring, or becoming dull. Since the pressed tube does not return to its original state, it is possible to check the amount of stored product used, and it is possible to prevent air from entering the stored product, so when dispensing the product. There is no risk of this scattering, and in particular, the tube neck and valve body can be molded into one piece, so there is no need for the conventional process of molding the valve body as a separate piece and assembling it with the tube neck. are doing.
