However, the conventional container with bellows spout has the following drawbacks. This occurs when, for example, the above-mentioned conventional container with a bellows spout contains a cleaning agent for a toilet bowl or the like. The cleaning agent is usually a chlorine-based solvent, and such a solvent is used for the base 56 and the packing 54. There is a risk of leakage from the space or between the packing 54 and the upper end 53 of the mouth 52. Since chlorine-based solvents are harmful as they come into contact with the skin and are dangerous, the method of pressure welding by screwing the above-mentioned structure is not possible if the outer cylinder is rotated even if it is slightly rotated for some reason. Has a risk of leaking harmful liquid as described above.

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to prevent bellows from leaking out of a liquid content between a container and a bellows body. It is to provide an attached container. Another purpose is that the bellows body generally has little rigidity in the axial direction and the left-right direction, and therefore it is difficult to mechanically hold the bellows body, which makes mounting and assembling in a container troublesome. It is a solution to provide a container with a bellows spout for which the bellows body can be easily attached to the container, that is, assembled and manufactured.

[0005]

The present invention which achieves the above-mentioned object is described as follows: a container 3 having a mouth portion 2 provided with a thread 1 on the outer periphery; a shoulder portion 4 on the upper portion of the mouth portion 2. An opening 6 having a diameter smaller than that of the mouth 2 and having a vertical main locking portion 5 on the outside; an inner cylinder 7 attached to the opening 6 and press-contacting the inside of the opening 6. And a main cylinder 8 having a main engagement portion 8 that press-fits with the main engagement portion 5 and an auxiliary engagement portion 9 on the outside, which is made of synthetic resin integrally formed by an annular end wall 11. Base 12; on the base 12,
Synthetic resin bellows body 14 integrally formed with the base end portion 13 and standing upright; a spout barrel 16 integrally formed at an upper end portion of the bellows body 14 and having a spout 15; the screw A top wall having an outer cylinder 19 having a screw groove 17 that is screwed into the thread 1 and a sub-engaging portion 18 that engages with the sub-locking portion 9, and a tubular middle leg 20 that contacts the spout barrel 16. A container with a bellows spout, characterized in that it comprises a synthetic resin outer lid 22 formed by 21. Further, the base 12 and the base end portion 13 of the bellows body 14 are the container with bellows spout integrally formed by adhesion. Further, the base 12 and the base end portion 13 of the bellows body 14 are the container with the bellows spout which is integrally molded.

The present invention is constructed as described above and has the bellows body 14
Is formed integrally with the base 12, and the base 12
Has its inner cylinder 7 pressed against the inside of the opening 6 of the container 3, thereby sealing this portion, and the main engaging portion 8 of the base 12 is the main locking portion of the opening 6. Since the base 12 is press-fitted to the portion 5, the base 12 cannot move upward, and therefore, for some reason, the base 1 cannot be moved, unlike the conventional example.
Even if 2 is slightly rotated, the sealing is not slightly damaged.

Further, since the bellows body has extremely low rigidity, it was difficult to mechanically mount the bellows body while holding it, but the present invention is constructed as described above, and the bellows provided on the base 12 is constructed. The body 14 is housed in the outer lid 22, the sub-engagement portion 9 of the base 12 engages with the sub-engagement portion 18 inside the outer cylinder 19 of the outer lid 22, and the spout barrel 16 includes the outer lid 22. It is stably accommodated and held in the radial direction and the vertical direction in contact with the inner leg 20, and in this state, the outer lid 22 is screwed onto the thread 1 of the container 3 so that the base 12 is held. Can be pressed into the opening 6 of 3
In this way, the bellows body spout can be attached to the container only by screwing the outer lid 22.

Further, when the base 12 and the base end portion 13 of the bellows body 14 are adhered to each other, when the bellows body 14 is bent to change the pouring direction, a force is applied to the base end portion 13 of the bellows body 14. Even when the pressure is applied, unlike the conventional pressure-contact type, it is possible to eliminate the risk of leakage of the content liquid from the base end portion 13. This action is the base 1
The same applies to the case where 2 and the base end portion 13 of the bellows body 14 are integrally molded.

Further, in the container with bellows outlet formed as described above, the direction of the bellows body 14 can be arbitrarily changed, so that the direction in which the content liquid in the container 3 is poured can be freely selected. For example, in a case where a toilet bowl cleaning agent is housed in this and the back side of the rim of the toilet bowl is washed, the bellows body 14 can be bent and directed in that direction, and the container can be pressed to pour out the washing liquid. . Moreover, in this case, because of the above-mentioned configuration, there is no fear that the cleaning agent will leak from the base portion. When not further used, the spout of the bellows body 14 is
It can be reduced and stored compactly in the outer lid 22.

Next, reference numeral 12 denotes a synthetic resin base, which has an inner cylinder 7 which is pressed against the inside of the opening 6, and a main engagement portion 8 which is pressed against and engaged with the main locking portion 5. The middle cylinder 10 is integrally formed by an annular end wall 11, and is attached to the opening 6 by pressure contact from inside and outside as shown in the figure.
Reference numeral 9 denotes a protrusion-shaped sub-locking portion provided on the outside of the middle cylinder 10. Reference numeral 24 is the upper end of the opening 6, and the upper end 24 is also in pressure contact with the inner surface of the end wall 11.

Next, 14 is a synthetic resin bellows body having a fold portion 25, and the base end portion 13 is formed in a flange shape,
A flange portion of the base end portion 13 is formed integrally with the base 12, and is attached as an example thereof. Further, this adhesion may be performed by an adhesive, or may be performed by high frequency welding, ultrasonic welding or the like. Further, in that case, as shown in FIG. 3, a double-folded flange-shaped base end portion 13 may be used. By forming in this way, the strength of this portion can be increased. It is possible to prevent damage to this portion and leakage of the content liquid. Further, the base 12 and the bellows body 14 are
It may be molded by integral molding of synthetic resin as shown in FIG.

Reference numeral 16 denotes a spouting tube integrally formed at the upper end of the bellows body 14 and having a spout 15 projecting at the upper end thereof. Next, reference numeral 22 denotes an outer lid made of synthetic resin, which is formed by an outer cylinder 19 and a top wall 21, and inside the outer cylinder 19, a screw groove 17 which is screwed with the thread 1 of the mouth portion 2 is formed. And has a sub-engaging portion 18 that engages with the sub-locking portion 9 and is engaged as shown in the drawing. Further, a cylindrical middle foot 20 is provided on the inner surface of the top wall 21, and the middle foot 20 is in close contact with the outside of the spout tube 16 and serves for sealing. Reference numeral 26 denotes a projecting inner member provided on the inner surface of the top wall 21 in the middle foot 20, and when the outer lid 22 is attached to the container 3, as shown in FIG. It has been inserted to seal the spout 15.

In this way, it is possible to surely seal both of the inner leg 20 and the inner leg 26. Next, in the present invention, as shown in FIG. 4, the base 12 and the bellows body 14 may be integrally formed. In this case, the base 12 is first formed by injection molding, and then the bellows body 14 is formed by blow molding. The container with the bellows spout formed in this way is used by unscrewing the outer cover 22 to unscrew the bellows body 14, pressing the container 3, and pouring the content liquid from the spout 15 into the container.

The present invention is constructed as described above, the bellows body 14 is integrally provided on the base 12, and the inner cylinder 7 of the base 12 is pressed against the inside of the opening 6 of the container 3. Has been
Moreover, since the main engaging portion 8 of the injection cylinder 10 is press-engaged with the main engaging portion 5 of the opening 6 in the vertical direction, the base 12 is not supported for some reason like the conventional example. Even if it is slightly rotated, it is possible to prevent the content liquid from leaking out between the bellows body 14 and the base 12, or between the opening 6 and the inner cylinder 7.
Further, since the bellows body 14 has low rigidity in the axial direction and the radial direction and is difficult to be mechanically held, the bellows body 14 which is integrally provided on the base is difficult to mount on the container mouth. Can be easily mounted by locking the sub-engaging portion 9 of the base 12 to the sub-engaging portion 18 of the outer lid 22 and housing the sub-engaging portion 9.

In addition, when the bellows body 14 is attached to the base 12, when the bellows body 14 is bent to change the pouring direction, a force is applied to the single unit 13 of the bellows body 14 by this. Also, unlike the conventional ones in which the contents are simply pressed against each other, it is possible to eliminate the risk of leakage of the content liquid from the base end portion 13. This action is the same as that of the base 12 and the base end 13 of the bellows body 14 integrally molded.

Further, since the direction of the bellows body 14 can be arbitrarily changed, the direction in which the content liquid in the container 3 is poured can be freely selected. For example, when storing a toilet bowl cleaner in a container formed in this way, on the back side of the rim of the toilet bowl,
The cleaning agent can be poured out by bending and pointing the bellows body 14. In that case, it is possible to eliminate the risk of the cleaning agent leaking from between the container 3 and the base 12 or between the bellows body 14.

Reference numeral 27 denotes a packing, and the filling port 15 is closed by this packing 27, but it is also made by sealing the middle leg 20 to the pouring tube 16. That is, it can be doubly sealed. Since the bellows body 14 provided on the base 12 is mounted inside the outer lid 22,
The bellows body 14 can be protected in handling before being fitted to the container and its mouth.

When not used further, the spout of the bellows body 14 can be reduced in the outer lid 22 and compactly stored.
