Abstract

PURPOSE: To prevent a shift between a dispensing direction of a nozzle and a bent direction of a lower end of a suction pipe from occurring to reduce an amount left in a container by making a constitution that a screw cap of a tank is rotated together with a container body when a screw is fit. CONSTITUTION: A tank 2 is positioned near an opening of a container body 1, and a suction pipe 3 is extended on a lower face of the tank. A stem 5 attached to an upper face of the tank 2 is always energized upward by a spring 6, while a nozzle is attached to an upper part of the stem to be set so that a dispensing direction of this nozzle coincides with a bent direction of a lower end of the pipe 3. A screw cap 8 is fit to a screw part 9 in this state to complete attachment of the tank 2 to the container body 1. The screw cap 8 is not integral with the tank 2 at this time and it can be freely rotate with respect to the tank 2, whereby the dispensing direction of the nozzle and the bent direction of the pipe can keep coinciding with each other, resulting in no contents left in the container.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispenser container for discharging cosmetics such as milky lotion and lotion from a nozzle at the tip of the stem by pressing the stem. The present invention relates to a dispenser container that reduces the remaining amount of cosmetics left behind in a container for structural reasons (hereinafter simply referred to as "leftover remaining amount").

[0002]

2. Description of the Related Art Generally, a dispenser container comprises a bottle-shaped container body, a tank having a screw cap, a suction pipe, and a stem with a nozzle, and the tank is located near the mouth of the container body. A suction pipe is extended on the lower surface of the tank, and a stem with a nozzle biased upward is provided on the upper surface of the tank. This tank is attached to the container body by screwing a screw cap into the threaded portion of the container body.

Further, since the tank has a pump function, when the stem is pressed, the inside of the tank is decompressed and the cosmetics inside the container body are stored in the tank via the suction pipe, and then the By pushing out,
The cosmetics once stored in the tank are discharged from the nozzle via the stem.

Generally, the suction pipe of the dispenser container is made of a flexible material, and its length is sufficiently long for the purpose of completely removing the cosmetics in the container body. The tip of the container was in contact with the bottom of the container body and was bent laterally, and the bending direction was directed toward the corner of the bottom of the container body.

Further, the discharge direction of the nozzle and the bending direction of the lower end of the suction pipe must always match. If the directions do not match, the amount of the remaining unfilled portion in the container increases as shown in FIG.

[0006] In the conventional dispenser container, the discharge direction of the nozzle and the curving direction of the lower end of the suction pipe are matched in advance, and in that state, the screw cap provided on the tank is screwed into the screw portion of the container body. It was a match.

By the way, since the conventional screw cap is integrally connected to the tank in a fitted state, when the screw cap is rotated and screwed into the threaded portion of the container body, the tank also rotates together with the screw cap. The stem and the suction pipe, which were also attached to the tank, were also rotating together.

[0008]

In the conventional dispenser container, the container body has a circular cross-sectional shape (that is, the planar shape of the bottom of the container body).
Even when the suction pipe was rotated together with the screw cap in the container body when the screw cap was fitted with the screw, the tip of the suction pipe did not forcibly contact the inner wall of the container body.

However, the container body is not limited to having a circular cross-sectional shape, but may have an elliptical shape (often an elliptical shape), and the above configuration is applied to this elliptical container body as it is. In this case, since the suction pipe rotates together with the screw cap and the tank in the container body when the screw cap is fitted, the curved lower end of the suction pipe is caught on the inner wall in the minor axis direction inside the container body ( Originally, the curved lower end of the suction pipe is adjusted according to the major axis direction inside the container body).

Therefore, if this is forcedly rotated,
There is a problem in that the ejection direction of the nozzles that are aligned with each other and the curving direction of the lower end of the suction pipe are deviated from each other, and as a result, the amount of the remaining unremoved residue increases (see FIG. 6).

An object of the present invention is to provide a dispenser container which solves the above problems.

[0012]

In order to solve the above-mentioned problems, a dispenser container according to the present invention is a dispenser container having an elliptical cross-sectional shape. A suction pipe is extended so as to reach the bottom in a curved state, and a stem with a nozzle is movably attached to the upper surface of the tank, and this stem is always urged upward. It is characterized in that the lower end of the suction pipe is made to coincide with the curved direction and the screw cap is configured to be freely rotatable with respect to the tank.

[0013]

In the present invention, when the screw cap is screwed, the tank does not rotate together with the container body together with the screw cap, and similarly the nozzle and the suction pipe do not rotate together with the screw cap. ing.

Therefore, when the screw cap is screw-fitted into the container body having an elliptical cross-sectional shape, the discharge direction of the nozzle and the curved direction of the lower end of the suction pipe are matched in advance, and the suction pipe is The curved lower end is positioned in the major axis direction of the container body.

In this state, when the screw cap is screw-fitted into the threaded portion of the container body while devising a device such as pressing the nozzle with a hand, the screw cap is in a free rotation state with respect to the tank. Only the nozzle rotates, and the nozzle, tank, and suction pipe are kept in their original position without rotating because of the anti-rotation measures. When the screw cap is screw-fitted, the tank is pressed from above by the pressing piece of the screw cap and is held and fixed to the container body.

[0016]

The present invention will be described in detail below with reference to the embodiments of the drawings, but the present invention is not limited thereto.

FIG. 1 is a front view of the present invention, and FIG. 2 is a side view of the same. The container body 1 may be formed of any transparent, semitransparent or opaque material, and its cross-sectional shape is shown in FIG. It has an elliptical shape.

In the dispenser container of the present invention, a tank 2 is located near the opening of the container body 1, and a suction pipe 3 is extended on the lower surface of the tank 2.

The lower end 3a of the suction pipe 3 is curved in the major axis direction (the direction is indicated by the dimension L) near the bottom 1a of the container body 1 and reaches the corner 4 of the container body 1 in the major axis direction in a curved state. The curved direction thereof coincides with the discharge direction of the nozzle 7. To take out the contents of the cosmetics, tilt the container body in the nozzle discharge direction (that is, if you tilt the container body in the major axis direction, the cosmetics will be collected in the corners of the major axis). It is possible to take it out. Since the material of the suction pipe 3 described here is a material having a certain shape retention property, if it is curved in advance, the curved shape can be sufficiently maintained in a normal use state.

A stem 5 is attached to the upper surface of the tank 2, and the stem 5 is constantly urged upward by a spring 6. When the stem 5 is pressed downward, the spring 6 is compressed and pushed. When the pressure is released, the elastic force for pushing back the stem 5 is stored.

Further, a nozzle 7 for discharging the contents is attached near the upper portion of the stem 5, and the discharging direction of the nozzle 7 is set so as to coincide with the bending direction of the lower end 3a of the suction pipe 3. It

After filling the cosmetics in the factory, the nozzle 7 and the suction pipe 3 are set in the tank 2 as described above, and in this state, the tank 2 is positioned near the opening of the container body 1 and the screw cap 8 is attached. The threaded portion 9 of the container body 1 is screw-fitted to complete the attachment to the container body 1.

In the present invention, since the screw cap 8 is not integrated with the tank 2 and is freely rotatable with respect to the tank 2, the screw cap 8 is screwed into the screw portion 9 of the container body 1. Even if they are combined, the tank 2 does not rotate together with the screw cap and keeps the state as it is.

Therefore, the nozzle 7 and the suction pipe 3 do not rotate with the rotation of the screw cap 8, and the suction pipe 3 forcibly abuts the inner wall of the minor diameter portion of the container body 1 to distort the set position. It doesn't get lost.

Here, an example of a specific structure for allowing the screw cap 8 to freely rotate with respect to the tank 2 will be described with reference to FIG.

A part of the outer wall of the tank 2 is laterally extended to form a collar piece 10, and a pressing piece 11 capable of pressing the upper surface of the collar piece 10 is formed on the screw cap 8. . The pressing piece 11 is formed near the upper end of the screw cap 8 so as to compete inward.

Further, a part of the tank 2 is extended upward to form the locking piece 12, and the locking piece 12 is inserted into the holding groove portion 14 of the ring member 13 to integrate the tank 2 and the ring member 13. Assembling (if necessary, the locking piece 12
It is preferable that the locking step portion 12a is formed on the ring member 13 and the locking projection 13a that can be engaged with the locking step portion 12a is formed on the ring member 13.

Therefore, the holding groove portion 14 of the ring member 13 is
Is put on the locking piece 12 of the tank 2 to engage the locking step portion 12a and the locking recess 13a, and the screw cap is attached to the tank in a freely rotatable state.

The ring member 13 is provided for the purpose of preventing the screw cap 8 from being inadvertently slipped out of the tank 2 after the screw fitting state with the screw portion 9 is released, and the lower end 13b of the ring member 13 is provided. Is located above the pressing piece 11 of the screw cap 8, so that even if the screw cap loosens and moves upward, the pressing piece 1
1 is in contact with the lower end 13b of the ring member so as not to fall off. That is, the ring member 13 serves as a retaining member for the screw cap 8.

When the ring member 13 is integrally attached to the tank 2, the lower end 13b of the ring member 13 can be prepared to prevent the pressing piece 11 of the screw cap 8 from moving upward. It will be a retainer.

Therefore, at the time of assembly, the lower surface of the collar piece 10 of the tank 2 is applied to the mouth of the container body 1 via the sealing member 15, and the screw portion 9 of the container body 1 is covered so that the screw cap 8 is covered from above. Apply to

Then, as the screw cap 8 is screw-fitted into the screw portion 9, the lower surface of the pressing piece 11 of the screw cap gradually presses the upper surface of the collar piece 10 of the tank 2, and finally the tank cap is formed by the screw cap. Will be fixed to the container body.

Next, when the nozzle 7 or the stem 5 is erroneously applied with force during use to rotate the nozzle or the stem with respect to the tank, the above-mentioned set state is disturbed. It is necessary to devise a key and a key groove, a spline shaft fitting, or some other suitable means so that the nozzle and stem do not rotate freely with respect to the tank.

On the other hand, since no accidental force is applied to the suction pipe 3, it is not necessary to provide special free rotation preventing means, but of course, free rotation preventing means may be provided.

A dispenser container employing the present invention,
Table 1 shows the test results comparing the remaining residual amount after the actual use with the conventional dispenser container.

[0036]

[Table 1]

Looking at the results of the above comparison test, the remaining amount of the opaque container is larger than that of the transparent container.
It has been found that the present invention has a smaller residual amount than the conventional one, regardless of whether it is a transparent container, a translucent container or an opaque container.

[0038]

As described above, according to the dispenser container of the present invention, even in the case of a container body having an elliptical cross-sectional shape, the discharge direction of the nozzle and the curved direction of the suction pipe can be stably maintained. Therefore, there is an excellent effect that the contents are not left unnecessarily and economical products can be used.

Further, according to the present invention, when a cosmetic that dislikes light is filled in an opaque container, the discharge direction of the nozzle and the bending direction of the suction pipe always match without being displaced even if the inside of the container body cannot be seen through. Therefore, there is a feature that the container can be used optimally simply by tilting the container body in the discharge direction of the nozzle.
