[0003] [Patent Document 1] JP 2022-157113 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the invention described in Patent Document 1, if liquid from a previous use is still present in the receiving container, the liquid cannot be removed hygienically, and in order to avoid this, it is necessary to always wash the receiving container after use, which creates a problem of complexity. In such cases, the problem of complexity can be eliminated by tilting the container and spraying the liquid directly into the mouth, but there is a possibility that too much liquid may be sprayed or the liquid may overflow from the mouth.

[0005] SUMMARY OF THE PRESENT EMBODIMENT In order to solve the above-mentioned problems in the conventional technology, an object of the present invention is to create a fixed-volume dispensing container that has a simple structure and is capable of reliably dispensing a fixed amount of content. [Means for solving the problem]

[0006] Among the means for solving the above problems, the main means of the present invention is: A measuring and dispensing container having a container body with a main mouth portion for filling and refilling a content and a discharge port portion for discharging the content, and a main cap for closing the main mouth portion, the discharge port portion includes a discharge nozzle that intersects with a container axis passing through the center of the main mouth portion and projects radially outward from the container axis, and a measuring portion that measures the content; a restricting member for restricting the discharge of the content and a discharge cap for closing the discharge nozzle are attached to the discharge nozzle, By squeezing the container body, the restricting member opens the discharge nozzle, allowing the measured content to be discharged. In the main means of the present invention, the container body is tilted to measure the content, and then the container body is squeezed, whereby the measured content can be discharged from the discharge nozzle.

[0007] Another means of the present invention is the above-mentioned main means plus a means in which the measuring section is configured to have a storage chamber provided in the trunk portion on the container body side and a discharge nozzle protruding into the storage chamber, and the storage chamber is formed to have a space surrounded by a peripheral wall and a bottom wall connected to the peripheral wall. In the above-mentioned means, the measured contents can be discharged directly from the discharge nozzle.

[0008] Another aspect of the present invention is any one of the above aspects, further comprising the step of making the restricting member a slit valve. With the above-mentioned means, the contents can be discharged when the container body is squeezed, and when squeezing is stopped, dripping from the discharge nozzle can be prevented and good liquid drainage can be achieved. Effect of the Invention

[0009] According to the present invention, with a simple configuration, the measured contents can be discharged from the discharge nozzle directly into the mouth without transferring the contents from the container body to a receiving container. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The fixed-dose dispensing container 1 of the present invention can be used as a container for dispensing contents L, such as mouthwash (gargle), into the mouth as described below, but can also be used as a container for dispensing gardening liquid (contents L) other than mouthwash. Note that the following description will be given assuming that the contents L is liquid, but the contents L are not limited to liquids and include fine powders and granules. In the following description, the direction along the container axis O passing through the center of the main mouth 11 will be referred to as the axial direction, up-down direction or height direction, and the direction perpendicular to the container axis O will be referred to as the radial direction.

[0012] First, the configuration of the constant volume dispensing container 1 will be described. As shown in Figure 1, the fixed-quantity dispensing container 1 is mainly composed of a synthetic resin container body 10 that contains the contents L and has a main mouth portion 11 for filling and refilling the contents L, such as a mouthwash, and a discharge port portion A for discharging the contents L. The container body 10 is a bottomed, cylindrical container having a cylindrical main mouth 11 standing on the upper part of a cylindrical body 13 connected upward from a bottom 14 via a shoulder 12 having a reduced diameter.

[0013] A male thread 11a is formed on the outer peripheral surface of the main mouth 11, and a main cap 40 having a female thread 42a formed on the inner peripheral surface of a side wall 42 is screwably provided on this main mouth 11. The main cap 40 is a cylindrical member with a top having a side wall 42 at the outer peripheral end of the top wall 41, and a packing 43 is arranged on the inner surface of the top wall 41, making it possible to improve the sealing performance between the main mouth 11 and the side wall 42.

[0014] The body 13 is partially formed with an inclined portion 15 that slopes upward to the right as shown in the figure from approximately the middle position in the height direction toward the container axis O, and the upper end of this inclined portion 15 is formed with a damming portion 16 that prevents the contents L from spilling out by folding it back into an inverted U-shaped cross section.

[0015] The discharge port section A is configured to have a storage chamber 17 provided between the damming section 16 constituting a part of the container body 10 side and the shoulder section 12, and a short cylindrical discharge nozzle 18 that intersects with the container axis O at the end of the storage chamber 17 and protrudes in a direction away from the container axis O. The storage chamber 17 and the discharge nozzle 18 configure the measuring section B. In addition, a restricting member 20 and a discharge cap 30 that closes the discharge nozzle 18 are attached to the open end that is the tip of the discharge nozzle 18.

[0016] The storage chamber 17 is configured to have a space surrounded by a peripheral wall 17A that is folded back from the blocking portion 16 and arranged radially outward from the body portion 13 that constitutes the container body 10, and a bottom wall 17B that is connected to the peripheral wall 17A. The tip portion on the radially outer side of the storage chamber 17 is formed in a cylindrical shape, and a male screw 17a for screwing the discharge cap 30 is formed on the outer circumferential surface. The discharge nozzle 18 is protruded from the tip of the storage chamber 17 with a diameter dimension smaller than that of the storage chamber 17, and an undercut-shaped engaged portion 18a is formed on the outer circumferential surface of the discharge nozzle 18.

[0017] The container body 10 having the above-mentioned configuration is made of a transparent or semi-transparent resin that elastically deforms inward when the body 13 is squeezed and returns to its original state before deformation when the squeeze is released. The container body 10 may also be configured such that at least the storage chamber 17 constituting the measuring section B is partially made of a transparent or semi-transparent resin.

[0018] The regulating member 20 has a drip prevention function and a liquid cutting function, and is composed of, for example, a cylindrical base 21 with an engaging portion 21a that engages with the engaged portion 18a, and a valve body 22 provided at the tip of the base 21, and is composed of, for example, a slit valve in which a cross-shaped opening and closing slit 23 is formed in the valve body 22.

[0019] The discharge cap 30 is formed integrally with a cylindrical side wall portion 31 that covers the tip of the storage chamber 17 and the regulating member 20, and a blocking wall 32 provided at the tip, and a female thread 31a is formed on the inner surface of the side wall portion 31 to screw into the male thread 17a formed at the tip of the storage chamber 17.

[0020] When the discharge cap 30 is screwed onto the outer peripheral surface of the discharge nozzle 18, the discharge outlet portion A can be blocked, and when the discharge cap 30 is unscrewed from the outer peripheral surface of the discharge nozzle 18, the discharge outlet portion A can be opened. Furthermore, the blocking wall 32 of the discharge cap 30 is formed so that its central portion protrudes inward, and when the discharge cap 30 is attached to the discharge nozzle 18 to block it, the protruding central portion of the regulating member 20 deforms the opening / closing slit 23 inward, maintaining it in a slightly open state.

[0021] Next, the function and effect of the constant-volume dispensing container 1 having the above-mentioned configuration will be described. Before use, the constant-volume dispensing container 1 is filled with the content L, the main mouth 11 is closed by the main cap 40, and the discharge nozzle 18 is closed by the discharge cap 30, in an initial state (see FIG. 1).

[0022] To measure and dispense the content L, the fixed-quantity dispenser 1 is tilted by about 90 degrees so that the discharge port A faces downward, as shown in Fig. 2. This operation causes the content L to overcome the blocking portion 16, and so it flows into the measuring portion B consisting of the storage chamber 17 and the discharge nozzle 18, where it can be temporarily stored (measurement start operation).

[0023] Here, if the volume of contents L flowing into the measuring section B is greater than the predetermined volume, it is advisable to tilt the constant-volume dispensing container 1 in the opposite direction to the previous measuring start state, as shown in Fig. 3. By performing this operation, a portion of the contents L will overcome the damming section 16 and return from the measuring section B to the inside of the body section 13, so that the contents L accumulating in the measuring section B can be adjusted to a predetermined volume (measurement adjustment operation).

[0024] Next, as shown in Fig. 4, by returning the constant-volume dispensing container 1 to an upright position, the measuring section B can be filled with the measured predetermined amount of contents L. At this time, it is possible to check whether the contents L accumulated in the measuring section B matches the predetermined amount (measurement confirmation operation). Then, if the contents L is less than the predetermined amount, the measuring start operation can be performed again, and if it is more, the measuring adjustment operation can be performed again to bring the contents closer to the desired predetermined amount.

[0025] After checking, as shown in Fig. 5, the discharge cap 30 is removed from the discharge port A, and the body 13 of the container body 10 is squeezed while the discharge nozzle 18 is directed toward the mouth M of the user. This increases the internal pressure in the body 13, and the contents L move radially outward inside the discharge nozzle 18 in the measuring section B, opening the opening / closing slit 23 constituting the restricting member 20, allowing a predetermined amount of the contents L to be discharged toward the mouth M of the user (discharge operation).

[0026] On the other hand, when the squeeze of the trunk 13 of the container body 10 is released to stop the discharge of the content L, the restricting member 20 closes the opening and closing slit 23. Therefore, this fixed-quantity dispensing container 1 effectively prevents dripping from the discharge nozzle 18 when the squeeze is stopped, and has a good liquid cutting function.

[0027] As described above, in the fixed-quantity dispensing container 1 of the present invention, it is possible to dispense the measured contents L directly into the user's mouth M, etc., without first transferring the contents L from the container body 10 to a receiving container such as a cup. Furthermore, the contents are discharged when the user squeezes the container, regardless of the inclination of the container, so the possibility of the discharged contents L spilling out of the mouth M can be reduced.

[0028] Furthermore, in the fixed-quantity dispensing container 1 of the present invention, the main mouth 11 and the discharge port A formed on the container body 10 are located at separate positions away from each other, and in particular, the main mouth 11, through whose center the container axis O passes, is configured to open upward when the container body 10 is placed on a flat surface. Therefore, operations such as filling and refilling the contents L at the main mouth 11 can be easily performed without being affected by the discharge port A.

[0029] Although the configuration and the effects of the present invention have been described above based on the embodiments, the present invention is not limited to the above embodiments. In the above embodiment, the restricting member 20 is a slit valve having an opening and closing slit 23, but it may be a silicon valve having a backflow prevention function. [Industrial Applicability]

[0030] The present invention can expand the range of applications in the field of fixed-volume dispensing containers to an even wider range. [Explanation of symbols]
