Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tube container having a flexible tube body and discharging the contents by a dispenser provided at the mouth.

[0002]

[Prior Art]

 In a tube container filled with a viscous fluid such as cosmetics and pharmaceuticals, instead of squeezing the tube body and pushing out the contents, a pump-type dispenser is provided at the mouth to discharge the contents. It is considered that a dispenser performs a pumping action by pushing a push button like a well-known spray container to discharge the contents (see Japanese Utility Model Publication No. 3-17059).

The dispenser has a structure in which the contents are sucked from the inside of the tube body and discharged from the nozzle opening of the push button to the outside, but the air is not introduced into the tube body from the outside, and the contents are discharged. Accordingly, the tube body is gradually crushed and becomes flat.

In order to discharge the contents from such a tube container, it is necessary to push the push button sufficiently to cause the dispenser to perform a pumping action. Therefore, the tube body must be held stably by hand. However, the tube body is flexible and bends easily as the contents decrease, and it becomes flat and difficult to hold stably, and it becomes difficult to hold it, which makes it difficult to push the push button. Further, there is a case in which the button cannot be pushed, which causes a problem.

[0005]

[Problems to be solved by the device]

 The problem to be solved by the present invention is that the conventional tube container provided with a pump-type dispenser for preventing the introduction of air into the mouth of the flexible tube body is accompanied by a decrease in the content of the tube body. Is easy to bend, and it is flattened, making it difficult to operate the push button of the dispenser.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a rigid suction pipe at the suction port of the dispenser and inserts it into the inside of the tube body, and the contents are obtained from the opening formed at the tip surface of the suction pipe and near the suction port of the peripheral wall With the structure for sucking in the contents, the object of stably and easily holding the tube main body and reliably discharging the contents is achieved even if the contents decrease.

[0007]

[Action]

 The tube body gradually collapses when the content decreases, but when the tube body is gripped, the suction pipe acts as a reinforcing core and does not bend, and the tube body does not become flat below the outer diameter of the suction pipe. It will be held stably and easily. The contents are sucked into the dispenser through one or both of the opening at the tip of the suction pipe and the opening near the suction port.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a tube body made of a soft synthetic resin, 11 is a dispenser mainly made of a hard synthetic resin, 31 is a hard synthetic resin. The tube body 1 has a well-known shape in which the lower part is flattened by the bottom sealing part 2 and the upper part is cylindrical, and the cap is attached to the mouth / neck part 3 protruding upward from the top part. 5 is attached by screw fitting.

The dispenser 11 is installed in a cylinder body 13 fitted with a piston 12, a push button 15 fitted and fixed in a discharge pipe 14 projecting from the piston 12, and a suction port 16 at the lower end of the cylinder body 13. An inlet check valve 17, an outlet check valve 18 installed at the tip of the discharge pipe 14, and a piston spring 19 are provided, and a flange 20 protruding from the outer peripheral surface of the cylinder body 13 is attached to the mouth / neck portion 3. When the cylinder body 13 is inserted into the mouth 4 surrounded by the mouth / neck 3 by placing the cap 5 on the upper surface of the cylinder 13 and the flange 20 and screwing the cap 5 into the mouth / neck 3. It is fixed to the tube body 1.

When the push button 15 is pushed and the piston 12 is pushed down, the contents of the cylinder chamber 21 surrounded by the cylinder body 13 and the piston 12 pass through the discharge pipe 14 and the outlet check valve 18 and the push button 15 is pushed. It is ejected from the nozzle 22. Further, when the push button 15 is released and the piston 12 rises by the spring force of the piston spring 19, the contents of the tube body 1 are fed into the cylinder chamber 21 through the inlet check valve 17, and at this time, the outlet check valve is provided. Since the valve 18 is closed and external air is not introduced into the tube body 1, the tube body 1 is crushed by the amount of the reduced content.

Next, the suction pipe 31 has a considerably large outer diameter so that it can be gripped with a stable hand, and its upper end is fitted and fixed in the suction port 16 and its lower end is in the tube body 1. It reaches the part where it changed from the cylindrical part to the flat part and opens downward. In addition to the downward opening 32, the suction pipe 31 has an auxiliary opening 33 at a position close to the upper end fitted into the suction port 16 of the peripheral wall, and further from the front end face of the lower end to the auxiliary opening 33. There is a + -shaped partition 34 reaching inside the room.

The contents mainly filled in the lower half of the tube body 1 are sucked into the dispenser 11 through the opening 32 at the tip, and the contents mainly filled in the upper half are opened at the upper part 33. Is sucked into the dispenser 11. Therefore, since the tube main body 1 is filled with only the contents by the dispenser 11 that blocks the introduction of air, and the contents can be sucked from both the lower part and the upper part, the push button It is possible to discharge an amount of the content corresponding to the stroke of 15 and without causing waste of leaving the content in the tube body 1. For that purpose, an opening may be additionally installed in the middle portion of the suction pipe 31.

The tube body 1 first has a shape filled with contents as shown in FIG. 2A, and finally has a shape as shown in FIG. 2B after the contents have been discharged. As can be seen from this figure, the tube body 1 has a thickness substantially equal to the outer diameter of the suction pipe 31 at the center where the suction pipe 31 is inserted, and it does not become flat beyond that, and the suction pipe 31 has a reinforcing core. Since the tube body 1 is prevented from bending with respect to the dispenser 11, the tube body 1 can always be held stably and easily, and therefore the push button 15 can be pressed accurately and sufficiently to ensure that the contents Can be discharged.

The dispenser 11 is usually a piston pump type having check valves on the suction side and the discharge side, but its specific configuration is not limited to that shown in FIG. Further, the suction pipe 31 may be configured such that the suction port 16 of the dispenser 11 is extended and formed integrally with the cylinder body 13.

[0015]

[Effect of the device]

 As described above, according to the present invention, in which the rigid suction pipe having the opening for sucking contents at the tip and near the upper end is fixed to the suction port of the dispenser and inserted into the tube body, the contents are reduced. Even if the tube body is stably and easily held and the push button can be operated accurately, the content can be discharged completely.
