Description

[Detailed description of the invention] (Industrial application field) This invention relates to liquid containers, and particularly to liquid dispenser containers equipped with a stopper structure that allows a predetermined amount of liquid to be dispensed with each dispense. This is related.

(Prior Art) Various types of liquid dispensing containers of this type have been proposed in the past, each having its own characteristics and effects.

For example, the metering container shown in Utility Model Application Publication No. 48-4163 can be summarized as follows: A metering container is fitted into the opening of the container, and the metering container has a vertical blind tube erected at the center of its bottom. A suction pipe is connected to the container with the other end reaching the bottom of the container.

(Problem to be solved by the invention) However, with such a container, especially when filling with the liquid content, the metering container must be unfitted into the container, and furthermore, the metering container must be fitted again after filling. Furthermore, the work process on the filling operator's side, such as applying the stopper, becomes complicated.

Furthermore, many other operational problems such as overflowing of the liquid contents cannot be avoided when fitting the metering container after filling the container with the liquid contents.

In view of this conventional situation, this invention was developed by squeezing or squeezing the body of the flexible container body from the outside to push out the filled liquid into the stopper metering section and measure it. In a liquid dispensing container of the type in which the measured liquid is poured out by removing the lid, the structure of the stopper measuring part including the lid is simple, and the work process especially when filling the liquid is simplified.
Furthermore, the present invention proposes a practically preferable container structure that eliminates many operational problems such as overflow during filling.

(Means for Solving the Problems) The present invention consists of a container body consisting of a pouring head with an open upper end, a flexible body, and a flat circular shape that can be fitted into the pouring head. formed in a ring shape,
A filling port with an engaging protrusion surrounding the upper part of the inner surface at the inner center of the annular portion, a measuring chamber formed within the annular portion and having an upper end opening as a spout, and a predetermined portion within this measuring chamber. a metering stopper body having a pouring pipe section provided up to a position corresponding to the measuring volume and opened at the bottom; a discharge tube connected to the lower opening of the pouring tube section and extending to the bottom of the container body; an inner stopper having a flange protruding from its periphery, and an engaging ridge that is fitted into the upper end opening of the filling port and that is engaged with the engaging protrusion on the outer circumferential surface; The flange of the inner stopper is attached to the inner circumferential surface of the retaining wall which is removably fitted to the dispensing head and is vertically provided on at least the lower surface, so that the flange of the inner stopper is engaged weaker than the engagement between the inner stopper and the annular part of the metering stopper. This liquid container is characterized by comprising a lid having retaining ridges around the lid for temporarily holding the container in a closed state.

The present invention particularly provides a measuring container as described above.
The metering stopper with a metering chamber that is fitted into the container body has a planar annular shape, and a filling port is formed inside the annular portion, and an engaging protrusion is provided around the inner surface of the annular portion to preliminarily fill the container body. The dispensing head is tightly closed, and the inner stopper is temporarily engaged with the holding ridge of the lid, and this engagement is weaker than the engagement of the inner stopper with the annular portion of the metering stopper, thereby allowing filling. After filling the container body with liquid from the mouth, by fitting the above-mentioned lid to the spout head, the temporarily engaged inner stopper is transferred to the filling mouth and tightly engaged. It was made so that it could be worn.

(Function) In the present invention, due to the above-mentioned configuration, the inner stopper is temporarily attached to the lid side before filling the contents, and after filling the container body with liquid from the filling port. By fitting the lid to the pouring head, the temporarily engaged inner stopper can be transferred to the filling opening and tightly engaged.
Therefore, complicated operations such as fitting and sealing the metering stopper after liquid filling, fitting the inner stopper, and fitting the lid become unnecessary.

Furthermore, after filling the liquid, the operation is as simple as simply fitting the lid on, eliminating the problem of overflowing the contents.

(Example) An example of the liquid dispensing container according to this invention will be described in detail below with reference to FIGS. 1 and 2.

FIG. 1 is a front view showing a main part of the container according to this embodiment in longitudinal section, FIG. 2 is a cross-sectional view taken along the line shown above, and FIG. 3 is a slope view of the metering stopper.

In each of these figures, a pouring head 2 with an open upper end and a threaded outer circumferential surface is formed at the top of a container body 1 consisting of a flexible body blow-molded from a soft synthetic resin material. be. The metering stopper 3, which has a planar annular shape and is fitted into the pouring head 2, has a flange 4 projecting from the upper periphery. A filling port 5 is formed in the upper part with a protruding engaging ridge 6 disposed around the circumference, and a measuring chamber 7 whose upper end opening serves as a pouring port is formed in the annular portion.
A dispensing pipe part 8 is provided in a part of the container body and reaches a predetermined measuring volume surface, and a dispensing pipe 9 extends to the inner bottom of the container main body 1 at a connecting part 8a opened downward at the lower part of the dispensing pipe part 8, A so-called dip pipe is connected.

The inner stopper 10, which is fitted into the upper end opening of the filling port 5 and also serves as a packing, has a flange 11 projecting from the upper periphery, and has the engaging protrusion on its outer circumferential surface. Anchoring ridge 1 tightly anchored to ridge 6
2 protrudes from the periphery. Further, a lid body 13 with an inner circumferential surface thread, which is removably fitted onto the pouring head 2, is attached to an inner upper end wall of the measuring chamber 7, which is located on the lower surface of the lid body 13 and is hung in an annular shape. It has a retaining wall 14 having a diameter slightly larger than that of the retaining wall 14 and a retaining wall 15 corresponding to the upper surface of the flange 4.
A small holding ridge 16 for temporarily holding the flange 11 of the inner stopper 10 is protruded from the inner peripheral surface of the inner stopper 10 .

However, in the case of a container with this embodiment configuration, the container manufacturer must tightly fit the metering stopper 3 to which the outlet pipe 9 is connected to the container body 1 from the upper end opening of the spouting head 2 in advance. At the same time as fitting the lid body 1
3, for the retaining ridge 14a of the retaining wall 14,
By temporarily engaging the flange 11 of the inner stopper 10, it is lightly held and prepared.

Then, at the liquid filling company, after filling the container body 1 in the above state with the desired liquid from the filling port 5 of the metering stopper 3, the lid 13 is placed in the pouring head 2.
Screw them together and fit them. Here, cover body 1 like this
3 is fitted, the inner stopper 10 temporarily held on the lid 13 has its engagement ridge 12 tightly engaged with the engagement protrusion 6 of the filling port 5 due to the screwing pressure. In addition, the flange 11 is pressed against the inner upper end wall surface of the metering chamber 7 to seal the filling port 5, and the retaining wall 15 presses the flange 4 of the metering stopper 3 against the upper end wall surface of the head 2. By doing so, leakage of liquid from each part can be reliably prevented.

Next, in order to use this dispenser container, the lid 13 is first removed, but at this time, the inner stopper 10, which was temporarily held by the holding ridges 16 of the lid 13, is not engaged by the retaining ridges 12. Since it is firmly attached to the mating ridge 6, it comes off from the holding ridge 16 and leaves the filling port 5 closed, leaving only the lid 13 to be removed. By removing the lid 13, the upper end of the measuring chamber 7 is opened as a spout.

Next, when the body of the container body 1 is grasped and squeezed lightly, the liquid inside is pushed out from the outlet pipe 9 through the spouting pipe part 8 and into the measuring chamber 7 of the measuring stopper body 3, filling it. When the squeeze button is released, a predetermined amount of liquid or more is returned into the container body 1 from the end of the spouting pipe section 8 at a predetermined position, and in this way, a predetermined amount of liquid is measured. Then, by tilting the container body 1 again so as to turn it upside down, the measured liquid in the measuring chamber 7 can be poured out.

(Effects of the device) As detailed above, this device forms a measuring chamber in the metering stopper that is tightly plugged into the pouring head of the container body, and pours into a part of this metering chamber to a position corresponding to a predetermined measuring volume. A dispensing pipe section is provided, and after the liquid pushed out by squeezing the container body fills the measuring chamber through this dispensing pipe section, the liquid other than the predetermined amount is returned and dispensed by opening the squeeze. Therefore, you can always measure a predetermined amount of liquid with simple operations.
Pouring is possible.

The above-mentioned metering stopper is made into a planar annular shape, and a filling port is formed inside the annular part, and an engaging protrusion is provided around the inner surface of the stopper, and the stopper is sealed in advance in the pouring head of the container body. By temporarily engaging the inner stopper flange with the holding ridge of the container, filling the container body with liquid from the filling port, and then fitting the lid to the dispensing head. Therefore, the temporarily engaged inner stopper can be transferred to the filling opening and tightly engaged, and the measuring stopper can be fitted and sealed after filling with liquid, and the inner stopper can be fitted and the lid body fitted. There is no need for complicated tasks such as putting on clothes.

In addition, after filling the liquid, the operation is as simple as simply fitting the lid on, eliminating the problem of overflowing the contents.
Furthermore, the filling operation can be simplified and mechanized easily, and the overall structure is relatively simple and can be provided at low cost.
