2. Description of the Related Art Dispensers capable of manually pouring, spraying or spraying a certain amount of liquid such as liquid cosmetics, various liquid detergents, finishing liquids, antifungal / disinfecting liquids, bleaching liquids, and water in containers. A container with a dispenser mounted on the top of the container body has been widely used. This dispenser is roughly classified into the following three types. One is a trigger dispenser that can change the internal volume of the pump by pulling / returning a trigger lever to dispense or eject liquid in a container, and the other is a trigger dispenser that pushes / returns a push head or a push button. A hand-pump type dispenser that can change the internal volume of the pump and dispense or eject the liquid in the container.

[0003]

In general, a container equipped with the above-mentioned trigger dispenser or hand-pump type dispenser has a flat horizontal cross section of the container body due to requirements for convenience, empty space during transportation and storage, and design requirements. They are often deformed. These containers with dispensers are often refilled at home and used repeatedly. However, when mounting the dispenser after filling the liquid in the irregularly shaped container body, if the mounting orientation of the dispenser does not match the direction of the deformed shape of the container body, not only is it not easy to use it, but also the space factor during transportation and storage is low. It will drop significantly and the design will be unsightly. In addition, when the dispenser is rotated by the external force during transportation and the azimuth relative to the container body changes, there is also a problem that the tightening of the screw cap is loosened and the liquid content leaks from the mounting portion. . Furthermore, when the trigger dispenser is mounted on the container body at the production plant, the center of gravity of the trigger dispenser is biased toward the nozzle side, so the neck is inserted with the neck inclined with respect to the container body. In some cases, inconsistencies may occur, which may cause a reduction in product yield.

[0004] The above problem is that the mounting of the dispenser to the container body depends only on the screwing of the screw cap, so that the dispenser can rotate with respect to the container body, and the relative movement between the container body and the dispenser. This is caused by the lack of a specified direction. Then, a container with a dispenser provided with positioning means for defining the mounting orientation of the dispenser with respect to the container body has been proposed. One example is shown in FIGS.

In FIG. 5A, a container 120 with a dispenser includes a container body 121 and a dispenser 1.
22 are connected to each other by a screw cap 123 which is rotatably fitted to a flange formed on the neck of the dispenser. In the vicinity of the opening 124 of the container body 121, an engaging rib 125 extending in the vertical direction is provided.
Are formed. At the base of the dispenser 122, an extension 127 is provided outside the screw cap 123 so as not to hinder the rotation of the screw cap. Inside the extension 127, the dispenser 122 is mounted in a predetermined direction. An engagement groove 126 extending in the vertical direction, which can be engaged with the engagement rib 125 only when the engagement is made, is formed.

In this container 120 with a dispenser, as shown in FIG. 5B, a dispenser 122 is arranged and inserted into the container main body 121 so as to have a specified mounting orientation, and the engaging rib 125 is inserted. When the screw cap 123 is rotated and screwed into the engagement groove 126, the dispenser 122 is fixedly connected to the container main body 121 without changing the mounting orientation, and an external force for rotating the dispenser 122 is applied. Even if added, the mounting orientation does not change.

However, this container 120 with a dispenser
However, since the positioning means consisting of the engaging rib 125 and the extension 127 is provided outside the container, the appearance is rugged, the design is limited, and commercialization is difficult. The present invention has been made to solve the above-described problems, and therefore, has as its object to define the relative orientation when the dispenser is mounted on the container body without affecting the external design, Another object of the present invention is to provide a dispenser-equipped container that prevents a mounting portion of the dispenser from being loosened due to inadvertent rotation of the dispenser and prevents liquid leakage.

[0008]

A flange 13 is formed on the cylindrical neck portion 12 of the dispenser 11, and a cylindrical screw cap 14 is rotatably mounted outside the flange 13. The screw cap 14 has a screw thread on the inner periphery. If this screw is engaged with the screw thread of the opening 2 and screwed in, the edge of the opening 2 and the flange 13 are brought into watertight contact. The container body 1 and the dispenser 11 can be completely separated from each other by completely contacting and mounting the screw, and then unscrewing the screw cap 14.

In this container 10 with a dispenser, a rib-like projection 3 extending vertically is formed inside the side wall of the opening 2 of the container body. On the other hand, a tongue plate 15 is hung down from the bottom of the neck 12 of the dispenser, and a receiving groove 16 is formed on the tongue plate 15 so as to extend vertically with the projection 3 interposed therebetween. 16 and
It serves as positioning means for defining the mutual mounting orientation of the container body 1 and the dispenser 11.

That is, the orientation is determined so that the projection 3 and the receiving groove 16 are engaged with each other, the neck 12 of the dispenser 11 is fitted into the opening 2 of the container body, and the screw cap 14 is screwed in. As a result, the projection 3 and the receiving groove 16 engage with each other inside the mounting portion 5, and the dispenser 11 is always mounted on the container body 1 in a fixed orientation.

In the container 10 with a dispenser, the relative orientation between the container body 1 and the dispenser 11 is fixed by the engagement between the projection 3 and the receiving groove 16 inside the mounting portion 5, so that the The dispenser 11 is separated when filling the liquid or refilling at home.
When the container is mounted on the container main body 1, inconvenience such as the mounting orientation of the dispenser not matching the orientation of the deformed container main body is prevented. In addition, an accident that the dispenser is inadvertently rotated and loosened by an external force during transportation or the like and the contents liquid leaks out is also prevented. Further, by engaging the projection 3 with the receiving groove 16, the problem that when the dispenser is mounted in the factory, the tilted fit of the dispenser into the container body due to the deviation of the center of gravity and the decrease in the product yield is solved. Both the projection 3 and the receiving groove 16 as positioning means are formed inside the side wall of the opening 2 and are inside the mounting portion 5 and cannot be seen from the outside, so that there is no problem in design at all. .

In the container 10 with a dispenser of the first embodiment, the mechanism other than the above-mentioned positioning means is the same as that of a conventional container with a trigger dispenser.

And an internal pressure of the variable capacity chamber 26 can be repeatedly increased or decreased by a trigger operation of the trigger lever 25. This trigger lever 25
Is urged by a spring 27 in a direction to increase the volume of the variable capacity chamber 26. Suction valve 20 and pumping valve 28
Are constituted by ball valves using steel balls, respectively. The liquid supply tube 23 is extended to the vicinity of the bottom 4 of the container so that the liquid in the container body 1 can be poured out without waste.

This container 10 with a trigger dispenser
When the trigger lever 25 is grasped and pulled by the hand, the volume of the variable capacity chamber 26 is reduced by the piston member 29 interlocked with the trigger lever 25 and the liquid therein is pressurized. Since the steel ball of the suction valve 20 closes the liquid passage and prevents the liquid from flowing back, the liquid is pushed up toward the nozzle part 24 by pushing up the steel ball of the extruding valve 28, and the liquid is formed from the nozzle part 24 into a liquid column shape. Dispensed in a mist or mist. Next, when the puller of the trigger lever 25 is loosened, the piston member 29 is pushed back in the direction of making the inside of the variable capacity chamber 26 a negative pressure by the bias of the spring 27. At this time, since the steel ball of the extruder valve 28 closes the liquid passage and prevents backflow from above, the liquid in the container body 1 passes through the liquid feed tube 23 and pushes up the steel ball of the suction valve 20. And is introduced and filled into the variable capacity chamber 26. By repeating the trigger operation, the liquid in the container can be continuously poured or ejected.

In the first embodiment, the trigger dispenser is used as the dispenser. However, the type of the dispenser is not limited to this, and may have a push head type or a push button type hand-pump mechanism. . The configuration and material of each of these members are not particularly limited.
