JP5528055B2 - Inner plug and container for powdered particles using the same - Google Patents

Description

  The present invention relates to an inner plug and a container for a granular material using the same.

Known as powder containers for storing clothes such as laundry detergent for clothes and detergent for automatic dishwashers, box-shaped containers with measuring spoons and bottle-shaped containers with measuring caps are known. ing.
In the usage mode of the box-shaped container, first, the lid is opened, the granular material is scooped up with an attached measuring spoon and weighed, and the measured granular material is put into a washing machine, an automatic dishwasher or the like. In a box-type container, the measuring spoon is put in the container and stored, so that powder particles adhere to the handle of the measuring spoon during repeated use, and the fingers are contaminated by the adhered powder particles. There is a problem that. In addition, when the remaining amount of the granular material is small, there is a problem that it is difficult to scoop with a measuring spoon.

  For bottle-shaped containers, the weighing cap is removed, the bottle is tilted, and the powder particles are swung out to the weighing cap for weighing. The outer circumference (grip part) of the measuring cap is not easily contaminated with powder particles. For this reason, the problem of contaminating fingers such as a box-shaped container is unlikely to occur.

  However, when the diameter of the outlet of the bottle-shaped container is large, a large amount of powder particles flow out instantaneously when the powder is shaken out to a measuring cap or the like, and the diameter of the outlet is small. In addition, although the outflow amount can be controlled, there is a problem that the replenishment of the particulate matter in the replenishment operation is complicated. That is, the bottle-shaped container is difficult to achieve both the ease of the weighing operation and the ease of the replenishment operation.

In order to solve such a problem, for example, a package in which a spout having a flow rate adjusting passage is provided in the mouth portion of the container body has been proposed (for example, Patent Document 1). According to this package, an arbitrary amount of powder particles can be shaken out regardless of the remaining amount of the powder particles and the inclination angle of the container body.
Further, a container with a powdered detergent composed of a cap provided with a tapered discharge port, an upper lid covering the discharge port, and a container body has been proposed (for example, Patent Document 2). According to this container, the granular material can be discharged little by little from the tapered discharge port during the weighing operation, and the cap can be removed to replenish the granular material from the opening during the replenishing operation.
Also, a bottom plate having a cap fitted into the mouth portion of the container body, having a swing hole formed in the top wall of the cap, and having a through hole on the inner surface of the fitting peripheral wall fitted in the mouth portion. There has been proposed a swinging container in which a swinging chamber is formed between the top wall and the top wall (for example, Patent Document 3).

However, in the technique of Patent Document 1, the outflow amount of the powder particles can be controlled. However, if the outflow amount is set to be small, the replenishment speed during the replenishment operation becomes slow. In addition, even if it sets so that the amount of outflow may become small, since a granular material will flow out in a wide state, there exists a problem of being spilled when it shakes out to measuring containers, such as a measuring cap.
In the technique of Patent Document 2, since the discharge port has a tapered shape, the cap is removed when returning excessively sprinkled powder particles to the container body or during replenishment work, and the work is complicated. In addition, the upper lid is small because it covers the tapered outlet, and only a small amount can be measured when functioning as a measuring cap.
In the technique of Patent Document 3, although the amount of powder particles flowing out can be controlled, the plug is removed when returning the powder particles that have been shaken back to the container body or during replenishment work, which is cumbersome.
Therefore, the present invention uses an inner plug that can be shaken out without spilling into a measuring container while controlling the amount of powder outflow, and that can easily replenish powder into the container body even during replenishment work. Aimed at containers for powdered products

Hereinafter, a container for granular materials according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the container 1 for a granular material includes a container main body 2 in which the granular material is accommodated, a lid 3 attached to a mouth 20 of the container main body 2, and a mouth 20 of the container main body 2. And the inner plug 5 fitted in the.

  The upper part of the container body 2 is a mouth part 20, and a male screw is formed on the outer peripheral surface of the mouth part 20.

The lid 3 also serves as a measuring container. As shown in FIGS. 2 (a) to 2 (d), the substantially circular ceiling wall 32 and the outer peripheral edge of the ceiling wall 32 are continuously provided downward. And a lower cylinder portion 34 having an internal thread formed on the inner peripheral surface. As shown in FIGS. 2 (c) to 2 (d), a step portion 36 coaxial with the lower cylinder portion 34 is formed on the inner surface of the top wall portion 32, and this step portion 36 is formed of the inner plug 5 described later. The first fitting portion 51 is fitted.
The lid 3 is attached to the container body 2 having a mouth portion 20 having a male screw formed on the outer peripheral surface.

  The inner plug 5 is formed, for example, by molding a material usually used for a powder container, such as polyethylene, polyethylene terephthalate, polypropylene, vinyl chloride, silicon elastomer, and urethane.

As shown in FIGS. 3 (a) to 3 (h), the inner plug 5 includes a substantially cylindrical main wall portion 50 that fits into the mouth portion 20, and a bottom wall portion that is connected to the lower portion of the main wall portion 50. 60. A flange-like first fitting portion 51 is provided at the upper peripheral edge of the main wall portion 50, and a second fitting that engages with the mouth portion 20 is provided in the vicinity of the upper peripheral edge of the outer peripheral surface of the main wall portion 50. A portion 53 is provided.
An outlet 52 is formed in the main wall portion 50 from the main wall portion 50 to the bottom wall portion 60 so as to communicate the inside and outside of the inner plug 5 and guide the powder in the container body 2 to the outside of the powder container 1. In addition, an inlet 54 is formed at a position facing the outlet 52 across the axis O to guide the powder into the container body 2 when the powder is replenished. The inflow port 54 has an opening area larger than that of the outflow port 52 and an opening width larger than that of the outflow port 52.
The main wall 50 is provided with a guide wall 56 that faces the outlet 52 and extends upward from the bottom wall 60. The guide wall 56 approaches the main wall 50 toward the upper end thereof. An arcuate inclined surface is formed. And when the granular material flows out by the outflow port 52 and the guide wall part 56, the flow path through which the granular material flows is formed.
The bottom wall portion 60 is an inclined surface that is inclined downward from the outlet 52 toward the inlet 54. The inclination angle α (FIG. 3C) with respect to the plane orthogonal to the axis O of the bottom wall portion 60 is preferably 30 to 60 °, more preferably 40 to 50 °.

The opening area of the outflow port 52 can be determined in consideration of the properties (particle diameter, fluidity, etc.) of the powder, the amount of powder used once, and the like. If the opening area of the outflow port 52 is too small, the outflow rate of the granular material will be slow, and if it is too large, it will be difficult to control the outflow amount of the granular material.
The opening width of the outlet 52 can be determined in consideration of the properties of the powder and the amount of powder used once. If the opening width of the outlet 52 is too narrow, the outflow speed of the powder will be slow, and if it is too wide, it will be difficult to control the outflow of the powder.

The opening area of the inflow port 54 can be determined in consideration of the properties of the powder and the like. If the opening area of the inflow port 54 is too small, the replenishment work of the granular material becomes complicated, and if it is too large, the amount of the granular material flowing into the inner plug 5 from the inside of the container body 2 through the inflow port 54 increases. There is a risk of spilling from other than the flow path.
The opening width of the inlet 54 can be determined in consideration of the properties of the powder and the like. If the opening width of the inflow port 54 is too narrow, the replenishment work of the granular material becomes complicated, and if it is too wide, the amount of the granular material flowing into the inner plug 5 from the inside of the container body 2 through the inflow port 54 increases. There is a risk of spilling from other than the flow path.

  Next, the usage aspect of the container 1 for granular materials is demonstrated using FIG. FIG. 4 (a) is a cross-sectional view of the powder container 1 for explaining the weighing operation, that is, the state in which the powder particles in the container body 2 are shaken out to the lid 3, FIG. 4 (b) It is a fragmentary sectional view of container 1 for powders explaining the mode at the time of replenishing granular materials in container main part 2, ie, replenishment operation.

  The granular material 70 to be measured is, for example, a laundry detergent for clothes having an average particle diameter of about 50 to 2000 μm, an automatic dishwashing detergent, or the like. As shown in FIG. 4 (a), the powder body 70 is weighed so that the lid 3 is unscrewed from the container body 2, the container body 2 is tilted so that the outlet 52 is positioned below, and the mouth 20 Is carried out by swinging the powder particles 70 into the lid 3. At this time, a part of the granular material 70 in the container body 2 flows into the inner plug 5 through the outlet 52, and the other part collides with the outer surface of the bottom wall portion 60, and then follows the inclined surface. It behaves so as to sink under the bottom wall portion 60 toward the outflow port 52. The granular material 70 that has entered the inside plug 5 flows out from the granular material container 1 in the flow of the arrow F1 with an arbitrary width while the flow path is restricted by the guide wall portion 56.

  As shown in FIG. 4B, the replenishment work of the granular material 70 into the container body 2 is performed in the inner plug 5 fitted in the mouth portion 20 with the mouth portion 20 facing upward. It is performed by pouring the powdered material 70. At this time, the granular material 70 poured into the inner plug 5 collides with the bottom wall 60 as indicated by an arrow F2, flows toward the inlet 54 according to the inclined surface of the bottom wall 60, and flows through the inlet 54. It circulates and is replenished in the container body 2.

According to the granular material container of the present embodiment, by providing an inlet separately from the outlet, even if the outlet is made smaller and the amount of outflow is controlled, the powder is quickly attached while the inner plug is attached. Can replenish things. In addition, by providing the guide wall portion, it is possible to sprinkle the granular material to the measuring container while being controlled to an arbitrary width. Furthermore, by forming the outflow port from the main wall portion to the bottom wall portion, it is possible to swing out the powder particles more smoothly.
In addition, since the outlet and the inlet are formed at positions facing each other across the axis O, it is easy for the particulate matter to flow out only from the outlet during the weighing operation, and the particulate matter can be covered without spilling. I can swing it into my body.

  Since the bottom wall portion is inclined downward from the outlet toward the inlet, the powder can smoothly flow into the container body from the inlet. In addition, since the bottom wall portion is inclined, in the powder particle measurement work (refer to FIG. 4A), the powder particles get over the bottom wall portion and flow into the inside plug from the inlet. Can be prevented. As a result, the granular material flows through the flow path between the guide walls, and the weighing operation becomes easier.

  Since the container for granular materials of this embodiment is provided with the 1st fitting part and the 2nd fitting part in the inner stopper, at the time of manufacture of the container for granular materials, Easy to attach the stopper. This point will be described with reference to FIG. FIG. 5A is a cross-sectional view of the powder container 1 showing a state before the lid 3 is screwed onto the container body 2. FIG. 5B is a cross-sectional view of the powder container 1 showing a state after the lid 3 is screwed into the container body 2 and the lid 3 is unscrewed again.

First, as shown in FIG. 5 (a), the lid 3 is placed on the upper end of the inner plug 5, and the first fitting portion 51 is fitted to the step portion 36 of the lid 3 to To do. Next, after filling the container body 2 with the powder and granule, the lid 3 is screwed into the container body 2 and the inner plug unit 4 is attached to the container body 2. When the lid 3 is screwed into the container body 2, the inner plug 5 is fitted into the mouth portion 20 and is strongly fitted to the mouth portion 20 by the second fitting portion 53.
When the lid 3 is unscrewed from the container main body 2 after the inner plug 5 is fitted into the mouth portion 20, the fitting strength between the second fitting portion 53 and the container main body 3 becomes the first fitting portion 51. Therefore, the inner plug 5 is detached from the lid 3 and remains in a state of being fitted to the mouth portion 20.

  Thus, the first fitting portion and the second fitting portion are provided in the inner plug, and the fitting strength between the second fitting portion and the container body is set to the first fitting portion and the lid. By making it stronger than the fitting strength, it is possible to increase the efficiency of manufacturing the powder container.

The present invention is not limited to the embodiment described above.

In the above-described embodiment, the opening area of the inflow port is larger than the opening area of the outflow port. However, the opening area of the outflow port may be equal to the opening area of the inflow port. May be larger than the opening area of the inlet. However, it is preferable to make the opening area of the inflow port larger than the opening area of the outflow port from the viewpoint of achieving both the ease of the weighing operation and the easy replenishment operation.
In the above-described embodiment, the opening width of the inflow port is wider than the opening width of the outflow port. However, the opening width of the outflow port may be equal to the opening width of the inflow port. May be wider than the opening width of the inlet. However, it is preferable to make the opening width of the inflow port wider than the opening width of the outflow port from the viewpoint of achieving both the ease of the weighing operation and the ease of the replenishment operation.

In the above-described embodiment, the first fitting portion and the second fitting portion are provided in the inner plug. However, the present invention is not limited to this, and the first fitting portion or the second fitting portion is provided. Only one of the parts may be provided, or none of them may be provided.
Moreover, although the step part which fits with a 1st fitting part is provided in the cover body, the member which fits with a 1st fitting part does not need to be provided in a cover body.

  In the above-mentioned embodiment, although the bottom wall part inclines below toward the inflow port from an outflow port, this invention is not limited to this, and the bottom wall part does not need to incline. However, from the viewpoint of facilitating the replenishment operation, the bottom wall portion is preferably inclined downward from the outlet to the inlet.

In the above-described embodiment, the outflow port is one substantially rectangular opening. However, the present invention is not limited to this, for example, as the inner plug 105 shown in FIGS. 6 (a) to (h). The outlet 152 may be composed of a plurality of slits 151.
In the inner plug 105, a plurality of slits 151 are formed from the main wall portion 50 to the bottom wall portion 60, and an outlet port 152 is configured by the plurality of slits 151. By making the outflow port into a slit shape like the outflow port 152, it is possible to prevent the lump of powder particles solidified in the container body 2 from flowing out. In the present invention, even if the outflow port has a slit shape, since the inflow port is formed, it is easy to replenish powder.
Moreover, the outflow port may have a circular shape, an elliptical shape, a lattice shape, or the like other than the slit shape. When the outlet is in a lattice shape, the same effect as in the case where the outlet is in a slit shape can be obtained.

Further, for example, a substantially fan-shaped guide portion 210 that protrudes upward from a part of the peripheral edge of the upper end of the main wall portion 50 may be provided as in the inner plug 205 shown in FIGS.

In the lid body 3 as shown in FIGS. 1 and 2, in the weighing operation, the powder particles adhere to the female screw of the lower cylinder portion 34, and the adhered powder particles adhere to the male screw of the container body 2. . Thus, the circumference | surroundings of the opening | mouth part 20 will be contaminated with the measured granular material.
On the other hand, in the lid 103 in which the measuring chamber 140 is formed, in order to measure the powder particles in the measuring chamber 140, the adhesion of the powder particles to the female screw of the lower cylinder portion 134 is reduced, and the powder around the mouth portion 20 is reduced. Contamination by particles can be prevented.
The lid 103 is preferably used in combination with the inner plug 205 (FIG. 6). This is because the particulate matter is guided to the measuring chamber 140 without being attached to the female screw or the like of the lower cylinder portion 134 by being guided by the guide portion 210.
In this embodiment, the weighing unit 141 has a bottomed cylindrical shape, but the weighing unit 141 may have a bottomed rectangular tube shape or the like.
