Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container for discharging an agent such as liquid or powder.
[0002]
[Prior art]
Conventionally, in a container in which an inner container is contained in an outer container, an outer nozzle coupled to the outer container and an inner nozzle coupled to the inner container are fitted to each other.
[0003]
[Problems to be solved by the invention]
A coupling member that is interposed between the outer container and the inner container and couples them is composed of two members that are fitted to each other, the outer nozzle and the inner nozzle. For this reason, if the fitting force between the outer nozzle and the inner nozzle is weak, the fitting of both nozzles is released and divided into two during transportation or use of the container, and the inner container separates from the outer container and falls off.
[0004]
An object of the present invention is to prevent the inner container from falling off in a container in which the inner container is coupled to the outer container.
[0005]
[Means for Solving the Problems]
According to the first aspect of the present invention, the inner container is housed in the outer container, the outer container and the inner container are coupled by a single coupling member, and the coupling member sealed to the outer container is disposed on the inner periphery of the outer intermediate cylindrical portion. A screw portion is provided, and an outer nozzle for the outer container is screwed to the back side of the screw portion, and a cap that covers the outer nozzle for the outer container and the discharge port for the inner container is placed on the front side of the screw portion. It is a container formed by screwing .

In addition, the measuring cap 50 has a cylindrical shape, includes a screw portion 51 to the coupling member 30 (screw portion 35) on the outer periphery of the base end, and a flange portion 52 that seals to the coupling member 30 on the intermediate outer periphery, A seal part 53 that seals to the discharge port 42 of the outer nozzle 40 and a seal part 54 that seals to the discharge port 34 of the inner nozzle 33 are provided on the back side of the ceiling.
[0008]
Here, the container 10 has the outer nozzle 40 and the inner nozzle 33 as cylinders as described above, and their central axes are arranged concentrically. An annular gap between the outer nozzle 40 and the inner nozzle 33 becomes a flow path for the agent A of the outer container 11.
[0009]
Further, the container 10 has the discharge port 34 of the inner nozzle 33 projecting outward from the discharge port 42 of the outer nozzle 40 in the axial direction, and the discharge port 42 of the outer nozzle 40 and the discharge port 34 of the inner nozzle 33 are respectively connected to the outer side. It has a trumpet shape that opens to the side.
[0010]
Moreover, the container 10 also makes the outer container 11 and the inner container 21 into a cylinder, and arrange | positions those center axes concentrically.
[0011]
The container 10 is assembled as follows.
(1) The assembly 60 of the coupling member 30, the outer nozzle 40, and the measuring cap 50 is prepared. The threaded tube portion 40A of the outer nozzle 40 is inserted into the annular recesses of the outer intermediate tube portion 30B and the inner intermediate tube portion 30C of the coupling member 30, and the screw portion 41 of the outer nozzle 40 is screwed to the screw portion 35 of the coupling member 30. Further, the threaded portion 51 of the measuring cap 50 is screwed onto the threaded portion 35 of the outer intermediate cylindrical portion 30B of the coupling member 30, and the threaded cylindrical portion 40A of the outer nozzle 40 is connected to the coupling member 30 at the proximal end of the measuring cap 50. The outer nozzle 40 and the inner nozzle 33 are sealed by the measuring cap 50.
[0012]
(2) Fill the inner container 21 with the agent B. Then, the screw portion 32 of the inner intermediate cylindrical portion 30C of the connecting member 30 constituting the assembly 60 of (1) is screwed to the screw portion 21A of the inner container 21.
[0013]
(3) Fill the outer container 11 with the agent A. Then, the driving portion 31 of the driving cylindrical portion 30A of the coupling member 30 constituting the assembly 60 connected to the outer container 21 of the above (2) is driven and coupled to the driving portion 11A of the outer container 11.
[0014]
According to this embodiment, there are the following operations.
(1) Since the outer container 11 and the inner container 21 are coupled by a single coupling member 30 and the coupling member 30 does not divide into two parts, the outer container 11 and the inner container 21 are two parts of the coupling member 30. Therefore, the inner container 21 can be prevented from falling off.
[0015]
(2) Since the coupling member 30 includes the discharge port 34 from the inner container 21 and the discharge port 42 from the outer container 11, the liquid contents can be discharged simultaneously by simply tilting the container 10.
[0016]
(3) By making the discharge port 34 of the inner container 21 into a trumpet shape, the liquid discharge property of the discharge port 34 of the inner container 21 is improved, and the liquid in the outer container 11 is discharged into the trumpet shape of the inner container 21. It is possible to prevent the wraparound to the inside of the outer side of the door. By making the discharge port 42 of the outer container 11 into a trumpet shape, the liquid discharge property of the discharge port 42 of the outer container 11 is improved.
[0017]
(4) By providing the coupling member 30 with the outer nozzle 40 as a separate member, the coupling member 30 can be provided with a discharge port 42 for the outer container 11 while simplifying the shape of the coupling member 30 as much as possible.
[0018]
(Other effects)
(5) Since the outer nozzle 40 and the inner nozzle 33 are arranged concentrically, as long as the inclination angle of the container 10 is the same, regardless of the circumferential grip position of the container 10 by the user, the agent A of the outer container 11 The agent B in the inner container 21 can be simultaneously discharged from any part in the circumferential direction of the nozzles 40 and 33 at a constant discharge amount ratio.
[0019]
(6) Since the outer container 11 and the inner container 21 are arranged concentrically, as long as the inclination angle of the container 10 is the same, the discharge port 42 of the outer nozzle 40 regardless of the circumferential grip position of the container 10 by the user. Each of the agent A in the outer container 11 and the agent B in the inner container 21 reaching the discharge port 34 of the inner nozzle 33 are set to the same discharge amount in any part of the outer container 11 and the inner container 21 in the circumferential direction, The agent A in the outer container 11 and the agent B in the inner container 21 can be simultaneously discharged from any portion in the circumferential direction of the nozzles 40 and 33 at a constant discharge amount ratio.
[0020]
(7) Since the inner nozzle 33 protrudes outward from the outer nozzle 40, the agent B discharged from the inner nozzle 33 falls in front of the outer nozzle 40, and the agent B in the inner container 21 enters the outer container 11. Can be prevented.
[0021]
(8) The agents A and B having different properties can be simultaneously discharged from the outer container 11 and the inner container 21 to the measuring cap 50 at a fixed discharge rate ratio, and both agents A and B can be mixed at a fixed mixing ratio. .
[0022]
(9) The flow guide 37 provided in the inner nozzle 33 functions as an insertion guide when the agent B is filled into the inner nozzle 33 and as an air replacement guide when the agent B is discharged from the inner nozzle 33.
[0031]
The container of the present invention may be one in which an outer nozzle is integrally formed with an outer container, an inner nozzle is integrally formed with an inner container, and the outer container and the inner container are coupled by a single coupling member.
[0032]
Further, the container of the present invention may be provided with one or more intermediate inner containers between the outermost outer container and the innermost inner container so that three or more multiple agents can be discharged simultaneously.
[0033]
In addition, the container of the present invention can be employed even when the outer container functions only to form the outer shell of the container and does not contain the contents and discharge it.
[0034]
