Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a variable metering cap for liquid dispensing containers and the like.

"Problems to be solved by conventional techniques and inventions" The present applicant has proposed that the outer cap can be fitted to the neck of the container to create a sense of unity, and by pulling up the outer cap, a measuring chamber can be formed to measure the amount of contents dispensed. We have already proposed a measuring cap with a similar structure (Kokoku No. 52-24192).
This cap includes an inner cap with a top wall that can be removably fitted to the neck of a container, and an outer cap with open upper and lower ends.A mating part is provided on the opposing surfaces of the cap so that they can rotate together and slide in the axial direction. At the same time, an inner cap fitting and holding part is formed on the upper and lower inner walls of the outer cap to prevent the cap from slipping out, and when both the inner and outer caps slide in the axially symmetrical direction, the inner cap top wall and the outer cap peripheral wall are fitted. It consists of an enclosed measuring chamber.

This cap can be opened by pulling up the outer cap.
Since a measuring chamber can be configured inside the cap, the amount of contents stored in the container can be measured using the cap without the trouble of preparing a special cup.Also, the outer cap can be pulled up and held firmly in the depressed position, and shaken. It does not move and has various effects such as ease of measurement, fitting and removal of caps, etc.

However, in this cap, the measuring chamber for measuring the liquid is made up of the top wall of the inner cap and the peripheral wall of the outer cap, so after using the measured liquid, the outer cap can be pushed down and attached to the container. When this occurs, the upper surface of the top wall of the inner cap is exposed while still wet with liquid, which may cause the risk of getting your hands dirty, and there is a risk that dust may adhere to the leaked area. There was room.

The object of the present invention is to propose an excellent variable metering cap that eliminates the drawbacks of the prior art described above.

``Means for Solving the Problems'' In order to solve the above problems, the variable metering cap of the present invention is designed to connect the container from the upper end of the peripheral wall 2, which is removably fitted to the outer surface of the mouth neck of the container, through the inwardly flange-like top wall 3. An inner cylinder 4 to be inserted into the body mouth and neck is vertically provided,
The cap main body 1 has a guide tube 5 that communicates with the inner tube 4 erected from the top wall, and a second inner tube 8 that is suspended from the back surface of the second top wall 7 to the inner surface of the guide tube is watertight and slidable. The second
It consists of an auxiliary cap 6 in which an outer cylinder 9 is vertically disposed vertically from the outer periphery of the top wall 7 and is fitted onto the outer surface of the guide cylinder 5 so as to be movable up and down.
A portion partitioned by the second top wall 7 and the second top wall 7 is configured as a measuring chamber.

``Function'' When not in use, the peripheral wall 2 is fitted to the neck of the container body and used as a cap. Moreover, when measuring the content liquid, after removing it from the container body, the liquid is injected from the upper end surface of the inner cylinder 4 and measured. Also, if the auxiliary cap 6 is rotated in a predetermined direction relative to the cap main body 1,
The auxiliary cap 6 is raised by a screw in the embodiment shown in FIGS. 1 and 2, and by an end cam action in the embodiment shown in FIGS. 3 and 4. As a result, the depth of the measuring chamber A defined by the inner cylinder 4 and guide cylinder 5 of the cap main body, the second inner cylinder 8 of the auxiliary cap, the second top wall 7, etc. increases, and its capacity increases. The above capacity increases according to the amount of rotation (rotation angle) of the auxiliary cap 6.

Of course, if the auxiliary cap 6 is rotated in the opposite direction from the above-mentioned state, the depth of the above-mentioned measuring chamber A will be reduced, and its capacity will be reduced.

Embodiment FIGS. 1 and 2 show an embodiment of the present invention, in which numeral 1 indicates a main cap, and numeral 6 indicates an auxiliary cap.

The main body 1 of the cap has an inner cylinder 4 which is inserted into the neck of the container from the upper end of a peripheral wall 2 which is fitted onto the outer surface of the neck of the container body through an inward flange-like top wall 3, and an inner cylinder 4 which is inserted into the neck of the container from the top wall. A guide tube 5 communicating with the guide tube 4 is erected.

The auxiliary cap 6 is attached to the inner surface of the guide cylinder with a second
A second inner cylinder 8 hanging from the back surface of the top wall 7 is fitted in a watertight and slidable manner, and an outer cylinder 9 hanging from the outer periphery of the second top wall 7 is fitted to the outer surface of the guide cylinder 5. The structure is such that the auxiliary cap can be screwed upward by rotation of the auxiliary cap with respect to the cap main body 1. In addition, 15 in the figure shows a screwing part.

Further, as a means for preventing the auxiliary cap 6 from coming off, a protrusion 11 is provided horizontally on the inner surface of the auxiliary cap outer cylinder 9, and a groove 12 into which the protrusion fits is bored on the outer surface of the cap main guide cylinder 5. has been done.

Further, although grooves 13 are provided on the entire circumference of the upper outer surface of the auxiliary cap outer cylinder 9 to facilitate movable operation, knurling may be provided in place of the grooves.

Also, matching marks 14 are provided on the upper outer surface of the main cap peripheral wall 2 and the lower outer surface of the auxiliary cap outer cylinder 9, so that the capacity when the auxiliary cap is rotated can be immediately determined.

3 and 4 show another embodiment of the present invention. In this embodiment, the upper end surface of the cap main body peripheral wall 2 and the lower end surface of the auxiliary cap outer cylinder 9 are each formed by an inclined surface 10. A cam mechanism is provided to fit the auxiliary cap so that it can move up and down.

``Effect of the invention'' As explained above, the variable metering cap of the present invention has the above-described structure, and the cap capacity can be changed according to the purpose of measurement by simply moving the auxiliary cap up and down relative to the main cap. In addition, the measuring chamber is composed of a portion that is not exposed to the outside and is partitioned by an inner cylinder, a guide cylinder, a second inner cylinder and a second top wall, and the cap is attached to the container body. At this time, since the opening of the measuring chamber opens into the container body, there is no risk of contaminating hands due to residual liquid, allowing for clean handling. or,
When not in use, it can be attached to the container body as a cap, so there is no risk of losing it.
