It is a state diagram at the time of use which concerns on this invention.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  1 to 4 are views illustrating a container having a function of preventing backflow of air in a tube discharge port according to the present invention.

  As shown in FIGS. 1 and 2, the tube container 1 of the present invention includes a tube 10, a neck portion 11, an inner cap 20, a cap 40, a checker 30 and the like.

  The tube 10 is a normal tube tube made of a flexible material, and the inside of the tube 10 is filled with contents, that is, liquid contents with or without viscosity. A neck portion 11 is formed to protrude from the upper end portion of the tube 10.

  The neck portion 11 has a shape in which an upper end portion is opened, and a locking step 24 and a locking groove 11a of an inner cap 20 described later are formed on the inner side surface, and the tube 10 is formed on the inner bottom surface thereof. A discharge port 12 through which contents are discharged is formed.

  The inner cap 20 is formed with a flange 21 projecting outward at the center of the outer side surface thereof, and the lower side portion of the flange 21 is inserted into the neck portion 11 of the tube 10 and joined to the upper side of the flange 21. The portion protrudes outside the neck portion 11. On the other hand, a locking step 24 that is inserted into the locking groove 11 a of the neck portion 11 and locked is formed on the outer surface of the lower side portion of the inner cap 20 that is coupled to the neck portion 11 of the tube 10. The inner cap 20 can be firmly coupled to the neck portion 11. In addition, an O-ring 25 is installed at the upper part of the locking step 24, and improves the sealing effect of the tube 10 by interposing between the inner cap 20 and the neck portion 11, that is, the content of the contents. Leakage can be prevented. A large number of ribs 23 projecting at regular intervals are formed on the inner surface of the inner cap 20 formed as described above, and spaces are provided between the ribs 23, and this space is the upper end of the inner cap 20. It communicates with the discharge port 22 formed in the section. Therefore, when the tube container 1 is used (pushed), the contents inside the tube 10 are discharged from the inner cap 20 through the space between the leaves 23 and the discharge port 22.

  The cap 40 has an outer diameter corresponding to the tube 10, and is screwed to the neck portion 11 of the tube 10, and a pad 41 that closes the discharge port 22 of the inner cap 20 is installed on the inner side of the cap 40. Here, the pad 41 is preferably formed of a flexible material such as rubber in order to maximize the sealing effect.

  That is, when the tube container is pushed regardless of the user's intention to use, the pad 41 is kept in close contact with the discharge port 22 and shuts off. It can be prevented from being discharged.

  As shown in FIG. 3, the checker 30 includes an insertion portion 31 that is inserted and fixed in a central portion that is formed of a large number of leaves 23 formed on the inner surface of the inner cap 20, and extends outward from the insertion portion 31. The expanded portion 32 that is extended to the rib 23 and is extended outwardly from the expanded portion 32 so that the end thereof is in contact with the bottom surface of the neck portion 11 and covers the discharge port 12 of the neck portion 11. Part 33 is included.

  At this time, the wing 33 is formed so that its thickness gradually decreases from the center to the end, and the wing 33 can be easily warped upward by the discharge pressure of the tube 10. Since the discharge port 12 of the neck portion 11 is opened by such warpage of the wing portion 33, the contents inside the tube 10 are easily discharged to the outside. Further, when the discharge pressure of the tube 10 is removed, the wing portion 33 that warps upward is quickly restored to the original state, and the discharge port 12 of the neck portion 11 is closed.

  On the other hand, a space 34 is formed between the checker 30 and the discharge port 12 of the neck portion 11 so that the discharge pressure of the tube 10 can easily act on the wing portion 33. The space part 34 formed in this way is formed in a dome shape by the lower surface of the extension part 32 and the wing part 33, so that the discharge pressure of the tube 10 can be easily distributed to the wing part 33 side. Therefore, the wing portion 33 opens (opens) the discharge port 12 while reacting quickly with the discharge pressure of the tube 10 or closes while being restored to this state.

  The operation relationship of the container provided with the air backflow prevention function in the tube discharge port according to the present invention configured as described above will be described.

  First, when the tube container 1 is not used, the end of the wing 33 of the checker 30 is in contact with the inner bottom surface of the neck 11 and covers the outlet 12 of the neck 11 as shown in FIG. The discharge port 12 is closed, and the contents of the tube 10 are not discharged.

  Thereafter, when the tube container 1 is used, as shown in FIG. 4b, when the tube 10 is pressed, the internal pressure of the tube 10 is increased by the pressing pressure (only the pressing pressure), and the content of the tube 10 is The gas is discharged to the space 34 between the checker 30 and the neck portion 11 through the discharge port 12. The contents discharged in this way secure a flow path by pushing up the wing 33 of the checker 30 upward and warping it by the gradually increasing discharge pressure.

  Therefore, the contents of the tube 10 are discharged to the neck portion 11 through the flow path (indicated by an arrow in FIG. 4B) secured in this manner, and the contents discharged to the neck portion 11 are also inside the inner cap 20. It passes between the leaves 23 and is discharged to the outside through the discharge port 22 of the inner cap 20.

  Thereafter, when the pressure applied to the tube 10 is removed, the pressed tube 10 and the wing 33 of the checker 30 that has warped upward are quickly restored to the original state, and the inner bottom surface of the neck portion 11 By contacting, the discharge port 12 of the neck portion 11 is closed to prevent the discharge of the contents, while the backflow of air is completely blocked to prevent the physical properties from being changed or altered.

  In addition, with the operation of the checker 30 as described above, the O-ring 25 installed between the inner cap 20 and the neck portion 11 of the tube 10 improves the airtightness and watertightness of the tube container 1, The leakage of contents can be reliably prevented.
