Description

[Technical Field]

[0001] The present disclosure relates to a measuring device, a container with a measuring function, and a method for assembling a container with a measuring function. [Background technology]

[0002] Conventionally, containers with a measuring function have been known that measure the fluid contents stored in a storage chamber within the container within the storage chamber and discharge the measured contents outside the container. In the container with a measuring function described in Patent Document 1, the measuring chamber that measures the contents and the discharge path that discharges the contents outside the container are separated by the container body. As a result, the structure of the container is complex. [Prior art documents] [Patent documents]

[0004] An object of the present invention is to provide a practical container with a measuring function. [Means for solving the problem]

[0005] The measuring device of the present invention is attached to a container and measures the fluid or granular contents stored in the storage chamber of the container in a measuring position in which the container is tilted in a specific direction from a resting position in which the container is placed on a horizontal surface with the bottom of the container facing downward in the direction of gravity.The measuring device comprises: a discharge path partition that partitions a discharge path through which the contents of the storage chamber are discharged from a discharge outlet to the outside of the container via a communication hole that connects the inside and outside of the container; and a measuring chamber partition that is provided on the opposite side of the discharge outlet of the discharge path partition and communicates with the storage chamber and the discharge path via an inlet hole and an outlet hole, respectively, and partitions a measuring chamber that measures the contents of the storage chamber.The inlet hole is provided in the measuring chamber partition at a distance from the outlet hole so that it is located above the outlet hole in the direction of gravity in the measuring position. [Effects of the Invention]

[0006] According to the measuring device of the present invention, the discharge path is defined by the discharge path defining portion of the measuring device, and the measuring chamber is defined by the measuring chamber defining portion of the measuring device, so that the discharge path and the measuring chamber do not need to be defined by the container, which simplifies the structure of the container and ultimately makes the container with measuring function practical.

DETAILED DESCRIPTION OF THE INVENTION

[0008] <Configuration of container with measuring function> 1 is a schematic diagram of a container with measuring function 1. The container with measuring function 1 comprises a container 10 and a measuring tool 20. The container with measuring function 1 has a measuring function of measuring the content 2 stored in the container 10 within the container 10 using the measuring tool 20. The contents 2 are fluids or granules. Fluid contents 2 include beverages such as water or juice, seasonings such as sauce or vinegar, and liquid detergents or medicines. Granular contents 2 include seasonings such as sugar or salt, and granular detergents or medicines.

[0009] <Container> 2 is a schematic diagram of a container 10. The container 10 defines a storage compartment 11. The storage compartment 11 is a space for storing the contents 2. A communication hole 12 is provided above the container 10 in the placed position. The placed position here refers to a position in which the container 10 is placed on a horizontal surface with the bottom 10a of the container 10 facing downward in the direction of gravity. The communication hole 12 is a hole for attaching the measuring tool 20 inside the container 10. The communication hole 12 provides communication between the inside and outside of the container 10. In this embodiment, the container 10 is a plastic bottle. In this case, the communication hole 12 functions as both an inlet for pouring the contents 2 and a drinking spout. Therefore, the opening area of ​​the communication hole 12 is smaller than the horizontal cross-sectional area of ​​the storage chamber 11 when the container 10 is in the placed position. In addition, the container 10 is transparent or translucent.

[0010] <Measuring tools> 3 is a schematic diagram of the measuring tool 20. The measuring tool 20 has a discharge path partition 210, a measuring chamber partition 220, a lid 230, a pouring upper limit display 240, and a measuring posture guide 250.

[0011] The discharge path dividing section 210 is formed in a tubular shape and divides a discharge path 211. Here, the discharge path 211 is a passage for discharging the contents 2 in the container 10 to the outside of the container 10. "Tubular" means a hollow, elongated shape. One end of the discharge path 211 functions as a discharge outlet 212. The contents 2 in the storage chamber 11 are discharged to the outside of the container 10 from the discharge outlet 212 via the discharge path 211. In this embodiment, the discharge path dividing section 210 is assumed to be cylindrical in shape.

[0012] Figure 4 is a schematic diagram of the measuring chamber partition 220. Figure 4(a) is a plan view, and Figure 4(b) is a cross-sectional view taken along the dashed line in (a). The measuring chamber partition 220 defines a measuring chamber 221. The measuring chamber partition 220 is provided with an inlet hole 222 and an outlet hole 223. The inlet hole 222 and the outlet hole 223 are spaced apart from each other. In this embodiment, the measuring chamber partition 220 is configured to have a cylindrical side wall 220a and disk-shaped upper and lower wall portions 220b and 220c. The inlet hole 222 and the outlet hole 223 are provided radially outward from the upper wall portion 220b so as to face each other across the center of the upper wall portion 220b.

[0013] The measuring chamber partition 220 is connected to the other end of the discharge path partition 210 so that the measuring chamber 221 and the discharge path 211 communicate with each other via the outflow hole 223 (see FIG. 3). Here, the other end of the discharge path partition 210 is the end of the discharge path partition 210 opposite the discharge port 212. It is preferable that the measuring chamber partition 220 and the discharge path partition 210 are configured to be detachable. In this embodiment, the measuring chamber partition 220 is configured to have a fixed wall portion 220d that surrounds the outer edge of the outflow hole 223. Furthermore, the outflow hole 223 is slightly smaller than the outer shape of the discharge path partition 210. Therefore, the measuring chamber partition 220 can be attached to the discharge path partition 210 by inserting the discharge path partition 210 into the fixed wall portion 220d, and the measuring chamber partition 220 can be removed from the discharge path partition 210 by pulling the discharge path partition 210 out of the fixed wall portion 220d.

[0014] The lid portion 230 closes the communication hole 12 of the container 10 (see FIG. 1). The lid portion 230 is configured to be detachable from the container 10. The lid portion 230 of this embodiment is formed in substantially the same shape as a plastic bottle cap. The lid portion 230 has a through-hole 231 (see FIG. 3). The lid portion 230 is attached to the discharge path dividing portion 210 with the discharge path dividing portion 210 passing through the through-hole 231. The lid portion 230 and the discharge path dividing portion 210 are in tight contact or sealed so that the contents 2 in the container 10 do not leak out through the through-hole 231.

[0015] The upper pouring limit indicator 240 indicates the upper limit of the content 2 that can be poured into the container 10 when the container 10 is in the placed position. The upper pouring limit indicator 240 is provided in the discharge path partition 210, and is arranged between the measuring chamber partition 220 and the lid 230. Here, the upper limit position does not correspond to the volume of the storage chamber 11, but corresponds to the upper limit capacity described below. The injection upper limit indicator 240 may be a component separate from the discharge path dividing section 210 that is attached to the discharge path dividing section 210, or may be the color or shape of the discharge path dividing section 210. In this embodiment, the upper limit fill indicator 240 is a disc-shaped component separate from the discharge path partition 210.

[0016] The weighing posture guidance unit 250 weighs the contents 2 in the container 10, and when discharging the weighed contents 2 out of the container 10, guides the container 10 in a specific direction in which to tilt the container 10 from the resting posture. Here, the specific direction is a direction in which the container 10 in the placed position is tilted so that the inlet hole 222 of the measuring chamber partition 220 is located higher than the outlet hole 223 in the direction of gravity. The measuring posture guiding section 250 may have the color and shape of the discharge path dividing section 210 or the measuring chamber dividing section 220, or may have the color and shape of a component separate from these components. In this embodiment, the end of the discharge path dividing section 210 on the discharge outlet 212 side is bent in a specific direction. In this case, the measuring posture guiding section 250 is the end of the discharge path dividing section 210 on the discharge outlet 212 side.

[0017] 1, when the measuring tool 20 is attached to the container 10, the discharge port 212 of the discharge path partition 210 is located outside the container 10, and the measuring chamber partition 220 is located inside the container 10. The measuring chamber partition 220 is located below the container 10 in the direction of gravity when the container 10 is placed in the installed position.

[0018] <How to use the measuring container> <How to measure contents> In the placed position of the container 10 shown in FIG. 1, the contents 2 in the storage chamber 11 shown in FIG. 2 flow into the measuring chamber 221 through the inlet hole 222 shown in FIG.

[0019] As shown in Figure 5, when the container 10 is tilted from the placement posture in a specific direction indicated by the measuring posture induction unit 250, the upper surface 2a of the contents 2 in the measuring chamber 221 is separated from the contents 2 outside the measuring chamber 221 within the storage chamber 11. In other words, the contents 2 in the storage chamber 11 are measured to approximately the capacity of the measuring chamber 221. Hereinafter, the posture of the container 10 in which the upper surface 2a of the contents 2 inside the measuring chamber 221 is higher in the direction of gravity than the upper surface 2b of the contents 2 outside the measuring chamber 221 for the first time is referred to as the measuring posture. The measuring posture changes depending on the amount of contents 2 stored in the storage chamber 11.

[0020] <How to remove contents> 6, when the container 10 is further tilted in a specific direction, the upper surface 2a of the contents 2 in the measuring chamber 221 becomes higher in the direction of gravity than the discharge outlet 212 of the discharge path partition 210, and the contents 2 in the measuring chamber 221 are discharged from the discharge outlet 212 to the outside of the container 10. Hereinafter, the attitude of the container 10 in which the upper surface 2a of the contents 2 in the measuring chamber 221 becomes higher in the direction of gravity than the discharge outlet 212 for the first time is referred to as the discharge attitude.

[0021] However, depending on the amount of contents 2 stored in container 10, it is conceivable that upper surface 2a of contents 2 in measuring chamber 221 may become higher in the direction of gravity than discharge port 212 before upper surface 2a of contents 2 in measuring chamber 221 becomes higher in the direction of gravity than upper surface 2b of contents 2 outside measuring chamber 221. In this case, contents 2 in container 10 will be discharged outside container 10 before being measured. For this reason, it is preferable that an upper limit capacity be set in container 1 with measuring function.

[0022] When the measuring tool 20 is applied to a specific container 10, the upper limit volume can be indicated by the height of the contents 2 when the container 10 is in the set position. The upper limit filling display unit 240 indicates the position of the upper surface of the contents 2 when the container 10 is in the set position with the upper limit volume of contents 2 stored therein, or a position lower than the upper surface. This position is the upper limit position mentioned above.

[0023] As described above, the container 10 of this embodiment is a plastic bottle. Therefore, the pouring upper limit display unit 240 of this embodiment indicates a position set based on the position of the upper surface of the contents 2 in the placement position of a plastic bottle of the same type (e.g., a 500 ml plastic bottle) distributed on the market. By checking the amount of contents 2 poured into the container 10 on the pouring upper limit indicator 240, the amount of contents 2 in the container 10 can be adjusted to be equal to or less than the upper limit capacity. Furthermore, if an injection port separate from the communication hole 12 is provided in the container 10, pouring the contents 2 into the container 10 while checking the pouring upper limit indicator 240 can prevent more contents 2 than the upper limit capacity from being poured into the container 10.

[0024] <How to inject the contents> First, with the container 10 placed as shown in Fig. 1, the upper limit position indicated by the pouring upper limit display unit 240 is confirmed. Next, as shown in Fig. 7, the measuring tool 20 of the container with measuring function 1 is removed from the container 10, and the contents 2 are poured into the container 10 through the communication hole 12. At this time, the measuring tool 20 removed from the container 10 may be locked to the container 10 by hooking the pouring upper limit display unit 240 of the measuring tool 20 onto the container 10. This makes it easier to pour the contents 2 into the container 10. Next, the measuring tool 20 of the container with measuring function 1 is attached to the container 10, and it is confirmed that the position of the top surface of the contents 2 in the container 10 does not exceed the upper limit position indicated by the pouring upper limit display unit 240.

[0025] Here, the amount of the contents 2 measured by the measuring chamber partitioning section 220 (hereinafter referred to as the "measured amount") depends on the volume of the measuring chamber 221. Therefore, if an attempt is made to increase the measured amount, the outer shape of the measuring chamber partitioning section 220 becomes larger. Furthermore, the minimum volume of the contents 2 in the storage chamber 11 that can be accurately measured by the measuring chamber partition 220 (hereinafter referred to as the "lower limit volume") depends on the height in the direction of gravity of the measuring chamber 221 in the placed position of the container 10. In more detail, if the upper surface of the contents 2 in the container 10 in the placed position of the container 10 is lower than the upper end of the measuring chamber 221, the measuring chamber 221 cannot be filled with the contents 2, and the measured amount becomes less than the volume of the measuring chamber 221.

[0026] Therefore, in order to achieve both an increase in the measured amount and a decrease in the lower limit capacity, it is necessary to expand the measuring chamber 221 in the horizontal direction of the measuring chamber 221 when the container 10 is placed in the mounted position, and to shrink the measuring chamber 221 in the direction of gravity when the container 10 is placed in the mounted position. On the other hand, the size and shape of the measuring chamber partition 220 are limited by the size and shape of the communication hole 12 of the container 10. In detail, the size and shape of the measuring chamber partition 220 need to be designed within a range that allows the measuring tool 20 to be inserted into the container 10 via the communication hole 12 of the measuring chamber partition 220 when the measuring tool 20 is attached to the container 10. As explained above, the measured amount and the lower limit capacity are limited by the size and shape of the communication hole 12 of the container 10.

[0027] Therefore, in this embodiment, the measuring chamber partition 220 is made of an elastic material or a shape-memory material so that it can be deformed to a size and shape that allows it to pass through the communication hole 12. Shape-memory materials include shape-memory polymers and shape-memory alloys. In addition, the upper injection limit indicator 240 is made of an elastic material or a material that is not a shape-memory material so that it has a size and shape that allows it to pass through the communication hole 12. This makes it possible to relax the restrictions on the above-mentioned metered amount and lower limit capacity.

[0028] <How to assemble a container with measuring function> 8 to 10 are schematic diagrams for explaining a method of assembling the container with measuring function 1. In Fig. 8 and Fig. 9, (a) is a side view of the measuring tool 20, and (b) is a plan view of the measuring tool 20. When attaching the measuring device 20 to the container 10, first, the measuring chamber partition 220 is deformed into a shape that allows it to pass through the communication hole 12 of the container 10, and then inserted into the container 10. These steps correspond to the "deformation step" and the "accommodation step," respectively. For example, as shown in Fig. 8, the measuring chamber partition section 220 is folded toward the discharge path partition section 210, and as shown in Fig. 9, the folded measuring chamber partition section 220 is wrapped around the discharge path partition section 210, and the deformed measuring chamber partition section 220 is inserted into the container 10 via the communication hole 12 as shown in Fig. 10. Subsequently, the shape of the measuring chamber partition section 220 is restored inside the container 10.

[0029] When the measuring chamber partition 220 is made of an elastic material, the shape of the measuring chamber partition 220 is restored inside the container 10 when the external force that has deformed the measuring chamber partition 220 is removed from inside the container 10. When the measuring chamber partition 220 is made of a shape-memory material, the shape of the measuring chamber partition 220 is restored by applying a stimulus such as heat or magnetic force to the measuring chamber partition 220 inside the container 10. Next, the lid portion 230 is attached to the container 10. In this embodiment, the lid portion 230 is fitted onto the drinking spout of a plastic bottle serving as the container 10 and then tightened.

[0030] In this way, when attaching the measuring device 20 to the container 10, the deformed measuring chamber partition 220 can be inserted into the container 10 through the communicating hole 12, thereby increasing the volume of the measuring chamber 221 partitioned by the measuring chamber partition 220 before deformation (after restoration), and thereby increasing the amount to be measured. Furthermore, since the measuring chamber 221 partitioned by the measuring chamber partition section 220 before deformation (after restoration) can be expanded in the horizontal direction when the container 10 is placed in the position, the height of the measuring chamber 221 in the direction of gravity when the container 10 is placed in the position can be lowered, thereby reducing the lower limit capacity. Furthermore, in this embodiment, as described above, the measuring chamber partition 220 and the discharge path partition 210 are configured to be detachable. This allows the container 10 to be replaced even if the container 10 does not have a special configuration for recovering the measuring tool 20.

[0031] <How to replace the container> More specifically, when replacing the container 10, the container 10 is cut as shown in FIG. 11. Next, the measuring chamber partition 220 is removed from the discharge path partition 210. This allows the measuring chamber partition 220 to be recovered. Next, as shown in FIG. 12, the lid 230 is removed from the container 10. This allows the discharge path partition 210 and the lid 230 to be recovered. Next, the recovered measuring chamber partition 220 is attached to the recovered discharge path partition 210. Finally, the measuring tool 20 is assembled into a new container 10.

[0032] <Effects of this embodiment> In this embodiment, the container 10 is made into a container with measuring function 1 by attaching a measuring tool 20 to the container 10. Therefore, a container with a simple structure can be used as the container 10 of the container with measuring function 1. This allows various containers, for example, empty plastic beverage bottles available on the market, to be used as the container 10 of the container with measuring function 1.

[0033] In this embodiment, the measuring chamber partition 220 is configured using an elastic material or a shape-memory material so as to be deformable into a shape that passes through the communication hole 12. This makes it possible to alleviate restrictions on the structure of the container 10 imposed by the structure of the measuring chamber partition 220 and restrictions on the structure of the container 10 imposed by the structure of the measuring chamber partition 220. For example, it is conceivable that the outer shape of the measuring chamber partition 220 will be enlarged in order to increase the measured amount or decrease the lower limit capacity. Even in this case, as long as the deformed measuring chamber partition 220 can pass through the pouring port or drinking spout formed on the container, the container can be used as the container 10 of the container with measuring function 1. Furthermore, as long as the deformed measuring chamber partition 220 can pass through the communication hole 12 of the container 10, the outer shape of the measuring chamber partition 220 can be enlarged, and as a result, the measured amount of the container with measuring function 1 can be increased or the lower limit capacity can be decreased, and containers with measuring function 1 with various measured amounts can be provided.

[0034] In this embodiment, the measuring tool 20 is provided with a lid portion 230. As a result, when a container with a lid that is commercially available, such as an empty PET beverage bottle, is used as the container 10 of the container with measuring function 1, the container with measuring function 1 can be formed simply by removing the lid from the container and attaching the measuring tool 20 to the container. Therefore, there is no need to drill a hole equivalent to the through-hole 231 in the lid of a container that is commercially available, or to tightly or tightly seal the lid of the container that is commercially available and the discharge path dividing portion 210 to prevent the contents from leaking from the container 10.

[0035] In this embodiment, the discharge path partition 210 and the measuring chamber partition 220 are configured to be detachable. As a result, when replacing the container 10, the measuring device 20 can be reused by cutting the container 10, removing the measuring chamber partition 220 from the discharge path partition 210, and removing the lid 230 from the container 10. Furthermore, there is no need to provide the container 10 with a special structure for retrieving the measuring chamber partition 220 from inside the container 10. Such a method of replacing the container 10 is particularly effective when a container that can be recycled even if cut up, such as an empty PET bottle, is used as the container 10 of the container with measuring function 1.

[0036] In this embodiment, the measuring tool 20 is provided with an upper pour limit indicator 240. This prevents the contents 2 from being poured into the container 10 in an amount greater than the upper limit capacity, allowing the contents 2 to be discharged from the container 10 after being correctly measured. In particular, when a container that is distributed on the market, such as a PET bottle, is used as the container 10 of the container with measuring function 1, there is no need to provide a structure indicating the upper limit position on the container that is distributed on the market.

[0037] In this embodiment, the container with weighing function 1 is provided with a weighing posture guiding unit 250. This makes it possible to prevent the container 10 from tilting in a direction completely different from the specific direction when discharging the contents 2 from the container 10 to the outside of the container 10, thereby enabling the contents 2 to be discharged from the container 10 after being correctly weighed.

[0038] In particular, in this embodiment, the measuring posture guiding unit 250 is provided on the measuring tool 20 rather than the container 10. Therefore, it is not necessary to adjust the position where the measuring tool 20 is attached to the container 10. Here, the specific direction is determined by the positional relationship between the inlet hole 222 and the outlet hole 223 of the measuring chamber partition 220. If the measuring attitude guiding unit 250 is provided in the container 10, it is necessary to adjust the position at which the measuring device 20 having the measuring chamber partition 220 is attached to the container 10 provided with the measuring attitude guiding unit 250 so that the specific direction coincides with the direction indicated by the measuring attitude guiding unit 250. In contrast, if the measuring attitude guiding unit 250 is provided in the measuring device 20, the measuring chamber partition 220 that determines the specific direction and the measuring attitude guiding unit 250 that indicates the specific direction are both provided in the measuring device 20, and therefore it is not necessary to adjust the position at which the measuring device 20 is attached to the container 10. Furthermore, when a container that is distributed on the market, such as a PET bottle, is used as the container 10 of the container with measuring function 1, there is no need to provide a structure that indicates a specific direction on the container that is distributed on the market.

[0039] <Other embodiments> In the above embodiment, the holes that function as the inlet and drinking spout of the container 10 are defined as the communicating holes 12. However, the holes that function as the inlet and drinking spout do not have to be defined as the communicating holes 12. For example, a hole that does not function as an inlet may be defined as the communicating hole 12, or a hole that does not function as a drinking spout may be defined as the communicating hole 12.

[0040] In the above embodiment, a plastic bottle is used as the container 10. However, the container 10 may be a container other than a plastic bottle that is distributed on the market, or may be a dedicated container designed for the container 1 with a measuring function.

[0041] In the above embodiment, the measuring chamber partition 220 of the measuring tool 20 is made of an elastic material or a shape-memory material. However, the measuring chamber partition 220 may be made of a material other than an elastic material or a shape-memory material.

[0042] In the above embodiment, the discharge path partition 210 and the measuring chamber partition 220 are configured to be detachable. However, the discharge path partitioning portion 210 and the measuring chamber partitioning portion 220 may be configured to be non-detachable, or the discharge path partitioning portion 210 and the measuring chamber partitioning portion 220 may be configured as an integral unit. Even if the discharge path partitioning portion 210 and the measuring chamber partitioning portion 220 are configured to be non-detachable in this way, when replacing the container 10, the measuring device 20 can be recovered from the cut container 10 by deforming the measuring chamber partitioning portion 220. Furthermore, the discharge path partitioning section 210 and the lid section 230 may be configured to be detachable. Even in this case, when replacing the container 10, the measuring tool 20 can be recovered from the cut container 10 by pulling the discharge path partitioning section 210 out of the lid section 230 toward the measuring chamber partitioning section 220.

[0043] In the above embodiment, the inner diameter of the fixed wall portion 220d is made slightly smaller than the outer diameter of the discharge path dividing portion 210, and the discharge path dividing portion 210 is inserted into the fixed wall portion 220d, thereby attaching the measuring chamber dividing portion 220 to the discharge path dividing portion 210. However, the attachment structure of the measuring chamber dividing portion 220 to the discharge path dividing portion 210 is not limited to this.

[0044] In the above embodiment, the inlet hole 222 and the outlet hole 223 of the measuring chamber partition 220 are provided in the upper wall portion 220b, but at least one of the inlet hole 222 and the outlet hole 223 may be provided in the side wall portion 220a.

[0045] In the above embodiment, the upper injection limit indicator 240 is formed from a material that is neither elastic nor shape-memory. However, the upper limit display section 240 may be made of an elastic material or a shape-memory material so that it can be deformed into a shape that passes through the communication hole 12. In this case, for example, the upper limit display section 240 can be made larger, so that the upper limit position can be clearly indicated by the upper limit display section 240.

[0046] In the above embodiment, the measuring tool 20 is provided with the lid 230, the upper pouring limit display 240, and the measuring posture guide 250. However, the measuring tool 20 does not have to have at least one of the lid 230, the upper pouring limit display 240, and the measuring posture guiding unit 250. Furthermore, the container with measuring function 1 does not have to have the lid 230, the upper pouring limit display 240, and the measuring posture guiding unit 250.
