Description

[Detailed description of the invention] Industrial field of application This invention relates to a dripping container for taking out contents such as cosmetic lotions, liquid detergents, and various liquid medicines little by little, and is particularly suitable as a container for volatile medicines. It is something.

Conventional technology Generally speaking, drop containers for lotion etc. are used by grasping the part near the bottom with one hand, so of course the size is limited. Most of them have an inclined cylindrical shape that expands downward, but in any case, the outlet at the top end is simply a small hole, and is kept covered with a cap when not in use.

Problems that the invention aims to solve: However, in conventional dripping containers, the outlet is just a small hole, so when the container is shaken with the outlet facing downward, a large amount of the contents may inadvertently spill out. Moreover, if one forgets to close the cap after use, there is a risk that the liquid content may evaporate or the container may fall over, causing the liquid content to leak.

The purpose of this invention is to provide a dripping container that can prevent the contents from evaporating to some extent even if the cap is forgotten, and can also prevent the contents from leaking to some extent even if the container falls over. .

Means to Solve the Problems In order to achieve the above objective, the inventor has conducted various research and has designed the outlet of the container to be structured such that a certain amount of the liquid comes out each time the container is shaken. At the same time, they discovered that it is sufficient to have a structure that also functions as a check valve that always prevents the contents from flowing out when not in use, and based on this knowledge, they came up with this invention.

That is, this invention has a short cylindrical outlet 2 at the upper end and a separate outlet 2 in the container main body 1, which has a slanted cylindrical circumferential surface 4 that gradually protrudes outward toward the bottom. A ball cylinder 11 is provided with small holes at the upper and lower ends to form upper and lower valve seats 9, 5, and several ridges 6 vertically arranged on the inner peripheral surface. A dripping container is provided which is surrounded by strips 6 and is rotatably enclosed and fitted.

The container main body 1 and the ball cylinder 11 in this invention are made of a material that is not corroded by the liquid inside, such as metal or plastic. In addition, the balls 8 are made of a material with a certain weight, such as metal or ceramics, in order to improve sealing performance at the upper and lower valve seats when the container is upright, and at the upper and lower valve seats when the container is tipped over. Made.

Embodiment Next, an embodiment of this invention will be explained with reference to the drawings. 1 is the main body of the container, and like the conventional container, a cap 3 is screwed into a short cylindrical outlet 2 provided at the upper end. The circumferential surface 4 is formed into, for example, a conical or pyramidal shape, gradually protruding outward toward the bottom.

Next, in this invention, the outlet 2 is provided with a small hole at the bottom to form a lower valve seat 5, and vertical ridges 6 on the inner peripheral surface, as shown in FIG. After a ball 8 is previously sealed inside the cylindrical container-like member 7, a seat cap 10 having a small hole and forming an upper valve seat 9 is fitted onto the seat cap 10 to form an integrated ball cylinder 11. Formed into a specific valve structure.

Effects and effects of the invention In this invention, due to the above structure, when the ball 8 is located between the upper and lower valve seats 9 and 5, a liquid flow path is formed through the ridges 6. If either seat 9 or 5 is fitted, outflow of liquid is prevented. As a result, it has the following effects and effects when used.

(B) For general use When using lotions, etc., shake the bolt up and down to let the liquid flow out, but in this device, as mentioned above, when the ball 8 hits the upper and lower valve seats 9 and 5, the liquid flows out. The ball 8 pressurizes the liquid in the direction of pushing out the liquid while moving up and down toward the seat cap 10, and the appropriate amount in the ball cylinder 11 is pumped out.
It can be taken out by turning it up and down. Therefore, when using the product, it is possible to determine the appropriate amount by shaking it up and down once, and even if it is shaken several times before use, it is possible to prevent overuse.

(b) When leaving the container without a cap after use It is common to leave the container upright after use, and in this case, the ball 8 fits into the lower valve seat 5, which prevents the volatile liquid from evaporating.

(c) Case of container tipping over (case without cap) As mentioned above, dripping containers for lotions and the like are generally cylindrical with an inclination that expands downward, but this device also has a container that gradually expands outward toward the bottom. Since the container body 1 is shaped to overhang, when the container is overturned, the vertical axis of the container main body 1 is inclined to one side. Therefore, the ball cylinder 1 coaxial with the vertical axis of the container
1 is also inclined. The ball 8 moves along this inclined surface in the direction of the seat cap 10 by connecting the lower valve seat 5 and the upper valve seat 8 in a straight line, and is guided by the ridges 6 stretched around the ball 8, and moves toward the seat cap 10 due to its own weight. The liquid is fed to the upper valve seat 9 by hydraulic pressure to prevent liquid leakage to the outside even without the cap 3.

As described above, this invention has a simple structure, reliable operation, and can be manufactured at low cost.
