DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed amount discharging cap for discharging a predetermined amount of powder or granules from a container.

[0002]

2. Description of the Related Art Various types of caps for quantitatively discharging seasonings such as salt and pepper, and powders and granules such as powdered detergents have been proposed in various types (for example, see Japanese Utility Model Publication No. 48-78). No. 523, No. 60-13803, No. 4
No. -1093, Japanese Utility Model Publication No. 4-54938). these,
The conventional fixed-quantity discharge cap tilts the container to which the cap is attached to allow the powder to flow out to the primary weighing chamber and raises the container so that the powder in the primary weighing chamber moves to the secondary weighing chamber. A predetermined amount of the granular material is stored in the secondary measuring chamber, and by tilting the container again, the granular material in the secondary measuring chamber is discharged to the outside from the discharge port to perform a constant discharge. At that time, the conventional fixed-quantity discharge cap has a problem in that it is difficult to discharge all the contents weighed into the secondary measuring chamber unless the container is tilted to an almost inverted state, and is difficult to handle. For this reason, the container is not easily tilted sufficiently when discharging, so that the remaining amount is generated in the secondary weighing chamber, and the amount of contents flowing into the primary weighing chamber also varies, so that the quantitative discharge is likely to vary. was there.

The plate reaches the flat portion 7 via the step surface 14 in the thickness direction of the plate.

On the other hand, the upper lid 3 has an annular wall 20, a top wall 22, which engages with the upper lid engaging wall 6 formed on the cap body 2.
And a primary weighing chamber wall 23 formed to hang down from the top wall to form a primary weighing chamber. Bottom of the annular wall 20 is branched to the annular inner wall 20 ₁ and the annular outer wall 20 ₂ to form the engaging groove of the annular and is adapted to engage the upper lid engagement wall 6 of the cap body. Top wall 22, in this embodiment, the low surface portion 22 ₁ low profile facing the opposite side is higher high surface 2 heights
It has a 2 _3, and therebetween an inclined surface portion 22 _2, and is formed as a whole inclined. Outlet 26 to the high surface portion 22 ₃ is formed, hinge-lid 27 for covering the exhaust outlet openably is provided by integral molding. Corresponding to the high surface portion 22 _3, an annular wall 20 that supports the high-surface has also increased, the outer edge 28 of the discharge port 26 is formed so as to match the inner circumferential surface of the annular wall 20.

The inclined plate 3 curved in an arc shape along the inner peripheral surface located below the outlet outer edge 28 of the annular wall 20.

The inclined plate is provided for adjusting the discharge angle at the time of discharging the contents, functions as a guide plate for guiding the contents from the secondary measuring chamber to the discharge port 26, and is preferably as shown in FIG. to, by the same angle theta ₂ between the inclined portion 13 of the cap body is inclined downwardly inward, when engaged with the upper lid to the cap body, a lower end inclined portion 1
3 It is desirable that it rests on the upper step surface 14 and is located on the extension of the inclined portion.

[0009] The primary metering chamber wall 23, as shown in FIGS. 1 and 2, has _two and a sectional semi-cylindrical large-diameter portion 23 and small diameter portion 23 _1, the inner diameter of the small diameter portion 23 ₁ is inlet equal to the opening diameter of 9, provided such that the lower end just located at the top of the cylindrical portion 11 of the insertion slot 9, a connecting portion 23 ₃ which connects the large diameter portion end from the small diameter portion end, turned It is formed so as to be in contact with the outer periphery of the cylindrical portion 11 of the mouth 9. Thereby, when the container is returned to the upright state during the primary weighing and after the primary weighing, the contents are prevented from flowing out to the space 15 of the cap body other than the secondary weighing chamber as shown in FIG. doing.

The fixed-quantity discharge cap according to the present embodiment is configured as described above, and the upper lid 3 is fitted to the cap body 2 to assemble integrally, and as shown in FIG. It is used by being attached to a container mouth of a container 41 filled with contents 40 such as. By tilting the container 41 from the upright state, the contents 40 are transferred from the inlet 9 of the cap body 2 to the primary measuring chamber 1 as shown in FIG.
The primary weighing is carried out until it is mechanically balanced in 8. By causing the container to its original state, the primary metering portion of chamber contents back to the container from the opening 12 of the inlet 9, the outer periphery of the insertion slot 9 mostly a large diameter portion 23 ₂ of the primary metering chamber Then, it flows out into the secondary weighing chamber 19 to perform secondary weighing, and the content of the fixed amount is stored in the secondary weighing chamber (FIG. 5A). When causing the vessel, since the state of the small-diameter portion 23 ₁ of the primary metering chamber is in contact with the top of the cylindrical portion 11 of the insertion slot 9, opposite the contents of the primary metering chamber and the secondary measuring chamber of the cap main body 2 Does not flow out into the space 15, the variation is reduced, and more accurate weighing is performed.

In this state, when the hinge lid 27 of the upper lid 3 is opened and the container 41 is tilted, as shown in FIG. 5B, the contents 40 stored in the secondary measuring chamber are moved by the gravity to the inclined portion 13 due to gravity. The outlet 26 along the inclined plate 30 of the upper lid.
From the container, and a fixed amount of contents can be taken out from the container. At this time, in this embodiment, since the inclined portion 13 of the secondary measuring chamber and the inclined plate 30 of the upper lid are both inclined by θ ₂ and are linear, the angle at which the entire contents can be discharged is θ.
Then, the entire amount can be discharged by tilting by θ ₁ (that is, θ−θ ₂ ). Thus, corner a small discharge angle by theta ₂ in comparison with conventional quantitative dispensing container, the container forcibly 9
Since there is no need to incline it to near 0 ° and turn it upside down, it is possible to discharge it very easily and smoothly. Since the inclination angle is reasonable, the container is discharged at a substantially constant inclination angle when the contents are discharged.

On the other hand, during discharge, the contents flow into the primary weighing chamber 18 through the opening 12 from the inside of the container to perform primary weighing, and after the discharge of the contents from the secondary weighing chamber is completed, the container is removed. When raised, the secondary weighing chamber is moved from the primary weighing chamber to the secondary weighing chamber, and the state shown in FIG. Hereinafter, FIG.
By repeating the state of (b), it is possible to repeatedly discharge the contents by a fixed amount. According to the present invention,
In particular, since the inclined plate 30 is provided, it can be ejected in a comfortable posture with a small inclination. Even when the ejection destination is relatively small, such as a coffee cup, it can be easily ejected without spilling. In addition, since there is no variation in the discharge angle at the time of discharging, the amount of the contents to be charged into the primary measuring chamber during discharging is also stable, and there is an advantage that more accurate weighing is performed.

Although the embodiment of the fixed amount discharge cap according to the present invention has been described above, the present invention is not limited to this embodiment, and various design changes can be made within the scope of the technical idea. For example, as shown in FIGS. 6A and 6B, the measuring chamber wall of the primary measuring chamber of the upper lid is not necessarily provided in the small diameter portion and the large diameter portion, and is formed in a cylindrical shape having only the large diameter portion. Is also possible. In that case, the primary weighing chamber and the secondary weighing chamber extend around the entire periphery of the inlet, but the partition wall 8 of the cap body 2
Is inclined such that the side located below the outlet is the deepest part, so that the secondary weighed contents are collected at the deepest part, so that the contents can be discharged smoothly as in the above embodiment. In addition, in FIG.
Is the primary weighing chamber wall, and the other configuration is the same as that of the above-described embodiment. Therefore, the same portions are denoted by the same reference numerals, and detailed description thereof will be omitted.

In the above embodiment, the inclined portion has the same inclination angle of the inclined plate. However, the inclined portion may not necessarily have the same angle, and may be formed to be larger than the angle θ _{2 of the} inclined plate. Further, the inclined plate 30 may be provided so as to reach near the top of the annular wall 20. Further, in the above embodiment, the top wall of the upper lid is varied in cross section height as a low surface portion, an inclined surface portion, and a rear surface portion, but this is for the purpose of design and material saving, and of course, simply has the same planar shape. May be formed.

[0015]

According to the quantitative discharge cap of the present invention, since the inclined plate is provided below the discharge port, the discharge angle can be made smaller than in the conventional case, and the secondary discharge can be performed without a large inclination of the container. The contents weighed into the weighing chamber can be discharged easily and reliably. Therefore, even when the discharge destination is relatively small, such as a coffee cup, the discharge can be easily performed without spilling. In addition, there is an advantage that the variation in the discharge angle at the time of discharging is reduced, the amount of the contents charged into the primary measuring chamber during discharging is stabilized, and more accurate weighing is performed.

[0016] The inclined portion of the cap body is formed so as to be inclined so as to be the same as or larger than the inclined angle of the inclined plate. By forming the portion located on the extension of the inclined plate so as to be inclined so as to be the deepest portion, the discharge from the secondary measuring chamber becomes smoother. Furthermore, the primary measuring chamber wall of the upper lid is formed with a large diameter portion and a small diameter portion,
By forming the small diameter portion so as to be in contact with the upper end of the inlet of the cap body, the contents in the primary weighing chamber do not flow out to the space portion 15 of the cap body 2 on the side opposite to the secondary weighing chamber, and the variation is reduced. Less and more accurate weighing is performed.
