[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a tube container which has a flexible tube body and discharges its contents by a pumping action of a dispenser. The present invention relates to a tube container having a configuration that can be used repeatedly.

[0002]

2. Description of the Related Art In a tube container filled with a viscous fluid such as cosmetics and pharmaceuticals, a pump-type dispenser is provided at the mouth instead of squeezing the tube body to extrude the contents. 2. Description of the Related Art A tube container which discharges a tube is known.

[0003] This type of tube container performs the same operation as a well-known spray container, that is, presses a push button of a dispenser to perform a pump action to discharge the contents. The structure is such that the tube body is not squeezed into the tube body from the outside, so the tube body collapses and flattens as the contents decrease, making it difficult to operate the dispenser.The dispenser has a rather complicated structure. The tube body is surrounded by a rigid outer container, the dispenser is fixed to the outer container, and the tube body is inserted into the outer container and screw-fitted to the dispenser so that it is not inexpensive. Is presented in Japanese Utility Model Publication No. 1-25611.

The tube container disclosed in this publication has an outer container so that the dispenser can be operated accurately even if the tube body becomes flat, and the dispenser is repeatedly used by replacing the tube body. By doing so, the effect of economical use can be expected.

However, in this tube container, the bottom surface of the tube body is located inside the bottom surface of the outer container so that the tube container can be left standing and stored.
For this reason, when the tube body is inserted into the outer container from the bottom and the screw at the mouth is screwed into the screw formed at the mouth of the dispenser, the tube body is firmly held and completely screwed. It is difficult to join, and there is a concern that the connection is incomplete and the contents leak. In addition, since the tube body filled with the contents does not have rigidity, it is easy to be crushed by twisting or applying a holding force more than necessary at the time of screw fitting, so that the contents are inadvertently pushed out from the mouth. This causes inconvenience.

[0006]

The problem to be solved by the present invention is that a flexible tube body and a pump-type dispenser for preventing air introduction are provided separately, and an outer container surrounding the tube body is provided. In a conventional tube container in which the dispenser is fixed and the tube body can be replaced, not only is it difficult to completely screw-fit the tube body to the dispenser, but also there is a complete handling problem. The connection is difficult and there is a fear that the contents may leak, and the contents may be accidentally pushed out at the time of screw fitting.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a tube body having flexibility, a threaded mouth, and at least a part having a non-circular cross section, and a non-circular tube. An outer container having a detent portion engaged with the cross-sectional portion and having an open bottom surface, and a cap provided with a screw that is screw-engaged with a screw of the tube body, the cap being rotated on the top of the outer container by the cap. It consists of a pump-type dispenser that prevents air introduction, which is freely mounted, so that the tube body can be completely screwed and connected to the dispenser without leaking or pushing out the contents. Is achieved.

[0008]

[Function] Open the mouth of the tube body, insert the non-circular cross section from the bottom into the outer container in phase with the detent part, and hold the outer container when the mouth is inserted into the cap. And rotate the cap. The tube body is non-rotatably engaged with the outer container, and the screw at the mouth engages with the screw at the cap and is pulled up. It is inserted into the main body, and the contents can be discharged. Also,
When separating the tube body, hold the outer container and rotate the cap in the opposite direction to release the screw fitting.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 denotes a tube body made of a soft synthetic resin. A flat portion is a non-circular cross-sectional portion 3 and a screw 5 is provided on an outer peripheral surface of a mouth portion 4 which protrudes into a cylindrical shape above a top portion, and is in a single state. The lid is screw-fitted to seal the mouth 4.

Reference numeral 11 denotes a rigid outer container made of a hard synthetic resin or metal, and a peripheral wall 12 having an inner diameter for allowing the upper cylindrical portion of the tube main body 1 to be inserted almost densely, and a top wall 14 having an opening 13. And when the tube body 1 is completely screwed into a dispenser 21 described later, the bottom is an open bottom surface 1
It has a height that is inside from 5. This outer container 11
In the embodiment of FIGS. 1 and 2, a non-circular cross section 3 has a detent portion 16 bulging to both sides corresponding to a portion which expands to both sides toward the bottom seal portion 2 in FIGS. In this embodiment, a non-rotating portion 17 formed of a cutout groove for inserting a portion expanding to both sides toward the bottom seal portion 2 and projecting outward.
have.

Referring to FIG. 1, the dispenser 21 has a piston 2
2, a push button 25 fitted and fixed to a discharge pipe 24 projecting upward from the piston 22;
An inlet check valve 27 installed at the suction port 26 at the lower end of the cylinder body 23 and an outlet check valve 28 installed at the tip of the discharge pipe 24
And a cap 30 fixed to the cylinder body 23 over its upper surface and having a skirt wall extending downward around the cylinder body 23.
The opening edge of the top wall 14 of the outer container 11 is fitted into an annular groove 31 provided on the outer peripheral surface of the skirt wall of the outer container 11 so as to be freely rotatable on the top of the outer container 11. A screw 32 is provided on the inner peripheral surface of the skirt wall of the cap 30 so as to be screw-fitted with the screw 5 of the tube body 1.

When the tube body 1 is inserted into the outer container 11 and completely screwed, the mouth 4 is in close contact with the cap 30 and the suction port 26 is inserted into the inside of the tube body 1 as shown in FIG. Is embedded. Push button 2 in this state
5 and the piston 22 is pushed down,
The contents of the cylinder chamber 33 surrounded by 3 and the piston 22 are discharged from the nozzle 34 of the push button 25 through the discharge pipe 24 and the outlet check valve 28. When the push button 25 is released and the piston 22 rises by the spring force of the piston spring 29,
The contents of the tube body 1 are supplied from the inlet 26 to the inlet check valve 2
7, the tube 1 is fed into the cylinder chamber 23. At this time, the outlet check valve 28 is closed to prevent external air from being introduced into the tube body 1, so that the tube body 1 is crushed by the reduced content. .

However, since the operation of discharging the contents is performed by holding the outer container 11 by hand, it can be stably held irrespective of the flattening and flattening of the tube main body 1, and the cap 30 is completely screwed in after fitting. Cannot rotate, so that the push button 25 can be operated accurately with the nozzle 34 directed in a predetermined direction.

Next, when connecting the tube body 1 to the dispenser 21, the mouth 4 is opened and the non-circular cross-section 3 is brought into phase with the detent portions 16 and 17 so as to be connected to the outer container 11. The screw 5 of the mouth part 4 is inserted from the open bottom surface 15,
When the outer container 11 is stopped by hand, the outer container 11 is gripped and held by hand, and the cap 30 is rotated by the other hand. The tube main body 1 is pulled up by the engagement of the screws 5 and 32 without being engaged with the outer container 11 and rotated, so that a complete screw fitting state as shown in FIG. 1 is obtained. When the contents are completely discharged, when the cap 30 is rotated in the opposite direction while holding the outer container 11, the screw fitting is released and the tube body 1 is pulled out from the open bottom surface 15.

Therefore, by preparing a plurality of tube bodies 1 for one set of the outer container 11 and the dispenser 21, it is possible to use the tube economically.

The dispenser 21 is usually of the biston pump type having check valves on the suction side and the discharge side.
The specific configuration is not limited to that shown in FIG.

[0017]

[Effect of the Invention] As described above, the dispenser is rotatably mounted on the outer container that wraps the tube body in a non-rotatable manner, and the book is connected to the dispenser by screw fitting without directly holding the tube body by hand. According to the invention, the tube body can be connected to the dispenser without inconvenience that the contents are leaked due to incomplete connection and the contents are erroneously pushed out at the time of screw fitting, and the tube body can be connected. Even if is flattened, the dispenser can be operated accurately to discharge the content by a predetermined amount, and can be used economically by replacing the tube body.
