[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a quantitative take-out cap that is attached to an opening of a container body and can take out a certain amount of powder from the container body by directing the opening downward, and in particular, completely inverts the container body. In particular, the present invention relates to a quantitative take-out cap that can smoothly discharge powder particles and can always take out a certain amount of powder particles from a container body.
[0002]
[Prior art]
Conventionally, a container for storing powdery or granular powders such as detergents and bleaches, and a fixed quantity extraction container that can repeatedly take out a certain amount of contents with a simple operation by turning the container upside down. Are known. For example, by placing the container in an inverted state, the particles in the container are stored in a measuring chamber provided in the cap, and then the container in the upright state is used to place the particles in the measuring chamber with the container. When the container is moved to the storage chamber between the cap and the container is turned upside down again, a certain amount of the granular material stored in the storage chamber is discharged from the discharge port, and a certain amount is again stored in the measuring chamber. When it returns to an upright state, it is comprised so that a fixed quantity of the contents can be repeatedly taken out by simple operation by storing a granular material in a storage chamber again from a measurement chamber. (For example, see Patent Document 1).
[0003]
In addition, there is known a container that can perform quantitative discharge to the end. This invention is a powder detergent formed by displacing the central axis of the discharge port portion of the quantitative discharge device from the central axis of the discharge flow channel to the center side of the opening of the container body, thereby remaining in the eccentric bottle Even if the amount of water is reduced, the powder detergent flows into the preparatory chamber from the inflow port by the amount of the inclination angle, so it is customary to tilt the eccentric bottle greatly from the beginning, and the powder detergent is contained in the eccentric bottle. Even if the number is reduced, the powder detergent easily flows into the preparatory chamber as much as the eccentric bottle is tilted, and there is little illusion that the powder detergent has disappeared, and the quantitative discharge is performed until the end. (For example, refer to Patent Document 2).
[0004]
In addition, a lid for closing the discharge port is attached to the discharge port so that the contents such as detergent can absorb moisture and dust does not enter the container. If the lid provided at the outlet is not fixed when opened, it may touch the powder discharged from the outlet and disturb the drop position of the powder. Therefore, conventionally, an opening / closing mechanism such as a three-point hinge has been provided on the lid so that the lid is held at a predetermined position at any position of opening / closing. (For example, see Patent Document 1).

JP-A-9-99966 [Problems to be solved by the invention]
However, in the conventional quantitative extraction container, the upper surface of the cap is formed perpendicularly to the center line of the quantitative extraction container, and the discharge port for the granular material is formed there. For this reason, if the quantitative extraction container is not completely inverted, the powder particles may remain inside the cap, and the predetermined amount of the entire amount of powder particles may not be discharged from the discharge port. Inverted completely downward, and in that state, the lower part of the quantitative extraction container was slightly shaken to the left and right to be discharged.
[0006]
Therefore, it takes time to take out the granular material such as detergent, and the lower part of the quantitative extraction container has been shaken to the left and right, so the granular material cannot be discharged smoothly toward one place, and the discharged granular material My body was scattered all over. On the other hand, if the powdery particles remain in the cap without completely inverting the fixed quantity extraction container, there is a problem that the amount of the powdery particles is not constant and the amount of the powdery particles is different each time the powder is taken out.
[0007]
In the present invention, the above-mentioned problems are solved, and a constant amount of powder particles can be easily and smoothly discharged from a discharge port by inclining the fixed amount extraction container at a predetermined angle without completely inverting the fixed amount extraction container. An object of the present invention is to provide a cap for quantitative removal that can be made to occur.
[0008]
Also, to provide a quantitative take-out cap having a simple and easy-to-use small lid that can hold the lid provided at the discharge port in any state of opening and closing with a simple structure and can obtain an appropriate click feeling with opening and closing. With the goal.
[0009]
[Means for Solving the Problems]
In the present invention, in order to solve the above-described problems, the quantitative removal cap is configured as follows.
[0011]
Specifically, the first configuration of the present invention is a fixed quantity take-out that is attached to the opening at the top of the container body and discharges a certain amount of powder from the container body when the opening is directed downward. A bottom member formed with an opening cylindrical body serving as a spout from which the opening protrudes, an outer cylindrical member extending upward from a peripheral edge of the bottom member, and an upper surface of the outer cylindrical member, A top wall disposed so as not to contact the upper end portion of the open cylindrical body, and an outer peripheral surface of the open cylindrical body so as not to contact the outer cylindrical member and the bottom member from a lower surface of the top wall. A cylindrical skirt portion that is suspended so as to cover the gap, an opening surface that is inclined downward with respect to the center line of the quantitative removal cap on the side of the top wall, and an opening in the opening surface Formed between the skirt portion and the outer cylinder member. An outlet communicating with the storage chamber has constituted the quantitative extraction cap and a lid covering the outlet openably.
[0013]
Further, in addition to the above configuration, the lid is disposed on the top wall with the lid body covering the discharge port and an openable / closable lid body, the lid body being connected to the lid body, and the lid being closed. In contact with the top wall surface in accordance with the opening operation, and when the lid is rotated to the open end, it comprises a middle foot that moves onto the opening surface and contacts the opening surface.
[0014]

It is connected in a flexible manner near the boundary between the opening surface and the top wall, and a U-shaped cut groove is formed in the center of the connecting portion between the lid supporting portion and the lid main body toward the lid supporting portion. The middle leg extending from the lid main body was provided to constitute a quantitative removal cap.
[0015]
According to said structure, since the discharge port is inclined, a predetermined amount can be reliably discharged without completely inverting a container main body, it is easy to use, and a substantially constant amount can always be taken out. In addition, since the discharge port is opened on the inclined opening surface, the lid that covers the discharge port can be made compact, so that it can be used without being obstructed, the amount of resin used can be reduced, and the weight can be reduced. In addition, the lid body can be fixed when opened, and an appropriate click feeling can be obtained when the lid is opened and closed. Further, since the lid can be made smaller, it is possible to improve the usability without being obstructed, and the amount of resin used can be reduced and the weight can be reduced.
[0016]
The container body 2 is a bottomed cylindrical container formed of synthetic resin or glass as shown in FIG. 7, and a fluid powder 50 such as a detergent and a bleaching agent introduced from the upper opening 3. Is housed inside. When the fixed quantity take-out cap 1 is attached to the opening 3 of the container main body 2, a fixed quantity take-out container 5 is formed, and when the fixed quantity take-out container 5 is inverted, the powder particles 50 can be taken out in a fixed quantity.
[0017]
The fixed amount taking-out cap 1 is a molded product made entirely of a covered cylindrical synthetic resin or the like, and is roughly composed of a bottom member 10, an outer cylinder member 11, a top wall 12, a lid 13, and the like, A measuring chamber 20 and a storage chamber 22 are formed.
[0018]
The outer cylinder member 11 is a cylindrical body that forms the outer peripheral wall of the fixed quantity take-out cap 1, and the bottom member 10 is fixed to the inner peripheral surface intermediate portion by undercut, welding, etc., and the lower end inner peripheral surface is A female screw 14 that is screwed into the screw portion 4 of the opening 3 is formed.
[0019]
A top wall 12 is integrally formed at the upper end of the outer cylinder member 11, and a skirt portion 15 is integrally suspended at the lower part of the inner surface of the top wall 12. The skirt portion 15 is disposed so that a lower end portion thereof does not come into contact with the bottom member 10 and covers an outer peripheral surface of an opening cylindrical body 25 described later with a predetermined gap therebetween.
[0020]
The bottom member 10 extends upward in the center of the bottom plate 24, and is formed with an opening cylinder 25 serving as a spout from which the opening 3 protrudes. As described above, the opening cylindrical body 25 has its tip inserted into the skirt portion 15 with a predetermined interval. The opening cylinder 25, the inner periphery of the skirt portion 15, and the inner surface of the top wall 12 constitute a measuring chamber 20 for measuring the powder particles 50. Furthermore, the outer periphery of the opening cylinder 25, the inner periphery of the outer cylinder member 11 (bottom member 10), and the bottom plate 24 constitute a storage chamber 22 in which the powder particles 50 are stored.
[0021]
Further, the top wall 12 has an opening surface 17 whose left side in FIG. 1 faces downward, and is within the surface of the opening surface 17 and between the outer periphery of the skirt portion 15 and the inner periphery of the outer cylinder member 11. As shown in FIG. 2, a discharge port 16 is formed. The inclination angle α of the opening surface 17 is about 20 ° to 60 ° from the horizontal, and when the container body 2 is naturally inclined in order to take out the granular material 50 as the contents, the opening surface 17 facing downward is horizontal. A close angle is preferred. Therefore, the inclination angle α of the opening surface 17 is appropriately determined depending on the diameter, length, overall weight, usage method, and the like of the container body 2.
[0022]
FIG. 2 shows a state in which the quantitative removal cap 1 is molded, that is, a state in which the lid 13 is opened from the connecting portion A of the top wall 12. As shown in FIG. 1, the lid 13 is connected to the top wall 12 by a connecting portion A located at the center of the top wall 12, and is further bent at the boundary between the opening surface 17 and the top wall 12. B is free to bend. Between the connecting portion A and the bent portion B is a lid support portion 29 having a hook 19 on the lower surface, and from the bent portion B to the tip is a lid body 27. That is, when the connecting portion A is bent from the molded state and the hook 19 is fastened, the lid support portion 29 is fixed to the top wall 12, the lid body 27 is supported flexibly by the bent portion B, and the lid 13 is bent. At B, the lid body 27 is bent and opened and closed. An engagement wall 28 that engages with the inner surface of the discharge port 16 is provided on the inner surface of the lid body 27, and the lid body 27 is engaged when the lid 13 is closed.
[0023]
Next, the lid 13 will be described in detail. The lid 13 is formed with folding grooves 31 at both the left and right sides at the position of the bent portion B. Further, between the folding grooves 31, a U-shaped cutting line 32 is formed as a groove as shown in FIG. It is formed in the support part 29. The U-shaped cutting line 32 forms a middle leg 30 on the lid 13 as shown in FIG. The middle leg 30 is bent at an angle α with the lid upper surface 27 and is disposed in parallel with the top wall 12 when the lid 13 is closed.
[0024]
The middle leg 30 does not come into contact with any surface when the lid 13 is closed. When the lid 13 is opened, the middle leg 30 rotates along with the rotation operation and contacts the upper surface of the top wall 12. When the lid body 27 is further rotated, elastic deformation is caused in the middle leg 30 and its peripheral portion, and a resistance force in the opening direction is caused in the lid 13. When the lid 13 is completely opened, the middle foot 30 moves to the opening surface 17 side beyond the boundary between the top wall 12 and the opening surface 17. Therefore, the resistance due to the opening movement is eliminated, and the lid 13 is held open as shown in FIGS. 4 and 5 because it contacts the surface of the opening surface 17.
[0025]
Further, when the lid 13 is closed, the middle foot 30 and the peripheral portion of the middle foot 30 are elastically deformed while the middle foot 30 crosses the boundary between the opening surface 17 and the top wall 12, that is, an appropriate resistance force and a feeling of opening, Make you feel a click.
[0026]
Next, the usage pattern of the quantitative extraction container 5 provided with the quantitative extraction cap 1 will be described with reference to the drawings. First, in order to fill the fixed quantity take-out container 5 with the granular material 50 such as a detergent, the fixed quantity take-out cap 1 is rotated and separated from the container main body 2, and the granular material 50 is removed from the opened opening 3. After that, the fixed quantity taking-out cap 1 is screwed onto the container body 2. The state is shown in FIG.
[0027]
In the case where the powdery particles 50 are taken out from the fixed quantity extraction container 5 filled with the powdery particles 50, as shown in FIG. 8, the fixed quantity extraction container 5 is turned upside down with the lid 13 being closed. . By this operation, the granular material 50 in the container main body 2 passes through the opening cylinder 25 and flows into the measuring chamber 20. When the surface position of the powder body 50 rises in the measuring chamber 20 and closes the opening of the opening cylinder 25, the dropping of the powder body 50 naturally stops. As a result, an almost constant amount of the granular material 50 is always measured by the measuring chamber 20.
[0028]
Subsequently, when the fixed quantity extraction container 5 is erected, as shown in FIG. 9, the powder particles 50 weighed in the measuring chamber 20 are spaced from the outer peripheral surface of the open cylindrical body 25 and the inner peripheral surface of the skirt portion 15. , And flows into a storage chamber 22 formed inside the bottom member 10 and the outer cylinder member 11 and outside the opening cylinder 25. As a result, a predetermined amount of the granular material 50 measured in the measurement chamber 20 is stored in the storage chamber 22.
[0029]
When the lid 13 is opened and the quantitative extraction container 5 is tilted so that the opening 3 is directed downward, the granular material 50 in the storage chamber 22 is discharged from the discharge port 16. Since the discharge port 16 is formed in the opening surface 17 inclined at the angle α, the opening direction of the discharge port 16 is directed directly downward by inclining the quantitative extraction container 5 by the angle α, and the particles from the storage chamber 22 The body 50 is smoothly discharged from the discharge port 16 without remaining in the fixed quantity taking-out cap 1. At this time, even if the granular material 50 in the container main body 2 flows out of the opening cylinder 25, the granular material 50 is accumulated and measured in the measuring chamber 20, and is not discharged from the discharge port 16.
[0030]
Further, since the lid 13 is formed with the middle leg 30, when the lid body 27 is opened and closed, an appropriate click feeling is generated in the opening and closing operation, and the lid body 27 is held in the opened state by the middle leg 30. In addition, since the lid body 27 covers only the opening surface 17, the lid body 27 can be reduced in size, is easy to use, and can discharge the powder body 50 without any trouble without the discharged powder body 50 coming into contact with the lid body 27. Can do. Further, the amount of resin used can be reduced, and the quantitative removal cap 1 can be reduced in weight.
[0031]
Furthermore, the fixed quantity taking-out cap 1 can be integrally molded in a state as shown in FIG. 2 with the inner bottom member 10 removed. In the present invention, instead of integral molding, the lid portion 13 may be individually molded and later assembled to the quantitative removal cap 1.
[0032]
The said embodiment is an example of the preferable cap for fixed quantity extraction of this invention, and this invention is not limited to this structure. For example, the cross-sectional shapes of the container body 2 and the skirt portion 15 as the internal structure, the opening cylinder 25, the bottom member 10 and the like are each independently or uniformly circular, elliptical, rectangular, or a modification thereof. It's okay.
[0033]
In addition to the screw method, the quantitative take-out cap 1 and the container body 2 are joined by, for example, forming corresponding concave / convex ridges on the peripheral surface of the joint between the quantitative take-out cap 1 and the container main body 2, respectively. The structure joined by these engagements, the structure which combined the screw | thread and the concave / convex ridge, etc. may be sufficient. Further, the shape and configuration of the lid 13 are not limited to those of the above embodiment.
[0035]
Furthermore, according to the cap for quantitative removal of the present invention, since the discharge port is opened on the opening surface inclined with respect to the top wall, the quantitative extraction container is tilted at an appropriate angle without being completely inverted. The powder can be smoothly discharged from the outlet without remaining in the cap for quantitative take-out, and a constant amount of powder can be discharged at all times. When opening and closing, a suitable click feeling is generated in the opening and closing operation, and the lid is held in an open state. The body can be discharged. In addition, since the discharge port is opened on the inclined opening surface, the lid that covers the discharge port can be made small, and the usability can be improved without being obstructed. Furthermore, since it is only necessary to provide a lid on the inclined opening surface, the lid can be made small and not in the way, and good usability can be obtained. Further, the amount of resin used in the lid portion can be reduced, and the cap for quantitative removal can be reduced in weight.
