Description

  The present invention relates to a nozzle-type container, and more particularly, to a low-cost nozzle-type container with a small number of parts, which can prevent dripping of the contents and can extract the contents to the end.

As shown in FIG. 5, the conventional general nozzle type container 60 has a mouth portion 63 having a nozzle portion 64, a shoulder portion 62, and a body portion 61 that are integrally formed, and after the contents are poured out. When the nozzle container 61 is returned to the original vertical position, the contents 65 hang down from the tip of the nozzle portion 64 along the outer peripheral surface of the nozzle portion 64. This is because the residual pressure in the container induces dripping of the contents after the contents are squeezed out or pushed out from a container such as a bottle container or a tube container. In particular, dripping is remarkable when the content is a low-viscosity substance. Then, the container shown in FIG. 4 was proposed as a conventional container which solves this. A conventional nozzle-type container 50 for preventing liquid dripping of the conventional contents is made of aluminum or synthetic resin, and a body part 51 for storing the contents, a shoulder part 52 provided at the tip of the body part 51, The mouth portion 53 is uniformly inclined upward from the shoulder portion 52 and the nozzle portion 54 continuous from the mouth portion 53. The mouth portion 53 having the nozzle portion 54, the shoulder portion 52, and the body portion 51 are integrally formed. It has been. The nozzle portion 54 has a valve chamber 57 having a suction port 55, a projecting port 56, a valve body 58 that reciprocates in the valve chamber 57, and a valve seat 59 that contacts the outer peripheral surface of the valve body 58. Yes. And the trunk | drum 51 which accommodates the content is comprised by uniform thickness. In such a conventional nozzle-type container 50 for preventing dripping, when the container is held by hand and the container is inclined, the contents are extracted by squeezing or extruding, and then the container is returned to the original vertical position. The valve body 58 quickly falls in the valve chamber 57 from the upper part to the valve seat 59, and a part of the contents remaining in the protruding port 56 is sucked into the valve chamber 57 to prevent dripping. It is.

And a body portion 5 that accommodates the content that continues below the shoulder portion 4. The nozzle part 2, the mouth part 3, and the body part 5 have a cylindrical shape, and a male screw 6 that is screwed into a cap (not shown) is formed on the outer peripheral wall of the mouth part 3. The lower end portion is closed by being flattened and bent double or triple toward the mouth 3. Further, a thin-walled portion 7 having a small thickness is formed in the vicinity immediately below the shoulder portion 4, that is, at the upper end position of the body portion 5. The thin-walled portion 7 is preferably formed with a length of 10 to 50 mm, preferably about 20 mm, downward from the shoulder 4. The thin portion 7 is t = 0.07 to 0.15 mm, preferably t = 0.09 to 0.13 mm. The thick portion 8 of the body portion 5 is T = 0.09 to 0.17 mm, preferably T = 0.11 to 0.15 mm. The thick portion 8 is preferably configured to be 10 to 40% thicker than the thin portion 7. The thickness of the thin portion 7 and the thick portion 8 of the trunk portion 5 can be appropriately changed in design depending on the type of contents, particularly the viscosity. That is, the tube container 1 can be of various thicknesses depending on the contents filled in the container. The thick part 8 of the body part 5 is only slightly thicker than the thin part 7 and has the effect of preventing dripping. Further, the thickness of the thin portion 7 must be designed to have a strength that does not cause damage to the trunk portion 5 when the trunk portion 5 is folded.

  The thin portion 7 is formed so that the outer peripheral wall has a stepped shape, but is not necessarily limited to this form, and may be formed thin so that the inner peripheral wall has a stepped shape. By comprising in this way, a restoring force can be given to the trunk | drum formed in the thick wall of the tube container, the air suction function can be generated, and dripping can be prevented. When the contents in the body 5 are squeezed out, the thin part 7 near the shoulder 4 can be easily folded into the shoulder 4 so that the contents in the shoulder 4 can be completely removed. It is possible to squeeze out and reliably prevent the contents from remaining in the tube container 1.
