Description

The present invention relates to a lid for a container.

Conventionally, containers have been known that include a container body that opens upward and a lid that closes the opening of the container body (see, for example, Patent Document 1).

Publication No. 7-2436

However, the container disclosed in Patent Document 1 does not have a portion on the top surface of the lid that can be grasped by the user, making it difficult for the user to grasp the lid and remove it, for example, when trying to remove the lid of a container placed on a high shelf, or the lid and container.

The present invention was invented in consideration of the above-mentioned problems with the conventional technology, and its purpose is to provide a container lid that, when a user raises their hand to lift the lid with one hand and attempts to remove a lid that is positioned above horizontal, can be easily grasped by inserting a finger (index finger, middle finger, ring finger, or little finger) that has passed over the top of the lid from the outside to the inside in a plan view into the finger insertion space.

The invention according to claim 1 is a lid for closing the top opening of a box-shaped container that opens upward. The lid includes a main plate portion. A protruding strip and a positioning protrusion are provided on the peripheral edge of the top surface of the main plate portion in a plan view, protruding above the top surface. The protruding strip includes an upright strip that stands up from the top surface and a horizontal strip that extends from the upper end of the upright strip toward the center of the main plate portion in a plan view. The horizontal strip forms a gripping portion integral with the main plate portion , which opens toward the center in a plan view and has a bottomed finger insertion space inside into which a finger can be inserted. The portion of the underside of the main plate portion where the positioning protrusion is formed is recessed upward.

With the container lid of the present invention, when a user raises their hand to lift the lid with one hand and remove a lid that is located above horizontal, they can easily insert the tip of a finger (index finger, middle finger, ring finger, or little finger) that has passed over the top of the lid from the outside to the inside in a plan view into the finger insertion space to grasp the gripping portion or hook the finger, making it easy to remove a lid that is located at a high position.

The present invention relates to a lid for a container, and more specifically to a lid for closing the top opening of a box-shaped container that opens upward. Below, a first embodiment of a lidded container 1 according to the present invention will be described with reference to Figures 1 to 4B.

As shown in Figure 1, the lidded container 1 consists of a container 2 and a lid 3. That is, the lidded container 1 is a set consisting of the container 2 and the lid 3. The lidded container 1 may of course be used alone, i.e., with one lid 3 placed on one container 2, or it may be used by stacking multiple containers 2 and placing the lid 3 only on the topmost container 2. Furthermore, multiple lidded containers 1, each with one lid 3 placed on one container 2, may be stacked on top of each other.

The container 2 is box-shaped and opens upward. In the first embodiment, the container 2 is rectangular box-shaped, having a bottom plate 21 that is rectangular in plan view and side plates 22 that are rectangular in side view and stand upright from each of the four sides of the bottom plate 21, and has an upper opening 20 surrounded by the upper edges of the side plates 22. The container 2 is integrally molded from resin.

As shown in Figures 2A to 3, the lid 3 closes the top opening 20 of the container 2. The lid 3 is molded from resin. In the first embodiment, the lid 3 includes a main body plate portion 31 and a hanging piece 32.

The main body plate portion 31 has a rectangular shape in plan view, roughly the same shape as the bottom plate 21 of the container 2. The hanging pieces 32 hang down from each of the four sides of the main body plate portion 31, and the entire hanging pieces 32 form a ring shape when viewed from below (in plan). When the top opening 20 of the container 2 is closed with the lid 3, the hanging pieces 32 fit over the upper ends of the side plates 22 of the container 2.

Positioning protrusions 33 are formed on the peripheral edge of the upper surface 310 of the main body plate 31 in a plan view. As shown in FIG. 2A, the positioning protrusions 33 are formed at the four corners of the main body plate 31, which is rectangular in plan view, and at the center of the peripheral edge along the long side 312. The positioning protrusions 33 protrude upward beyond the portions of the upper surface 310 of the main body plate 31 other than the positioning protrusions 33. As shown in FIG. 2C, the portion 331 of the lower surface 311 of the main body plate 31 where the positioning protrusions 33 are formed is recessed upward. Ribs 332 spanning the width of the recess are formed in multiple locations on the portion 331 of the lower surface 311 along the longitudinal direction of the recess.

When multiple lidded containers 1 are stacked, the bottom plate 21 of the upper lidded container 1 is stored between the positioning protrusions 33 formed on the top surface 310 of the lower lidded container 1. As a result, the positioning protrusions 33 restrict movement of the bottom plate 21 of the upper lidded container 1 placed on the top surface 310 of the lid 3, preventing the upper lidded container 1 from moving and falling off the lid 3.

Furthermore, the main body plate portion 31 has portions with different upper and lower surface heights at different positions in a plan view. Specifically, as shown in Figures 1 to 3, it has a low step portion 314 with the lowest upper and lower surface heights, a middle step portion 316 with higher upper and lower surface heights than those of the low step portion 314, and a high step portion 318 with higher upper and lower surface heights than those of the middle step portion 316. The middle step portions 316 are formed in the center of each of four regions formed by dividing the upper surface portion 310 of the main body plate portion 31 in two equal parts along the long side 312 and along the short side 313 in a plan view. Furthermore, the high step portions 318 are formed in the center of each middle step portion 316.

The container has a step 315 between the low step 314 and the middle step 316, and a step 317 between the middle step 316 and the high step 318. The provision of these step portions 315, 317 makes the main body plate 31 less likely to bend or twist, i.e., less likely to deform. Furthermore, water adhering to the upper surface 310 tends to flow from the high step 318 to the middle step 316, from the middle step 316 to the low step 314, and drop from the low step 314 (the edge of the upper surface 310), thereby preventing water from accumulating on the upper surface 310. Water adhering to the upper surface 310 is primarily intended to include rainwater falling on the lid 3 of a lidded container 1 placed outdoors, and cleaning water or cleaning solution used to clean the lid 3. Furthermore, the top surface 310 of the main body plate 31 does not have any recesses formed in any area other than the positioning protrusions 33 and the protruding strips 34 described below. To explain further, the top surface 310 has a low step 314, a middle step 316, and a high step 318 in any area other than the positioning protrusions 33 and the protruding strips 34, but does not have any downwardly recessed areas. Therefore, by tilting the lid 3, water adhering to the top surface 310 can easily fall off the edge of the low step 314.

As shown in Figures 2A to 4B, the gripping portion 4 is provided on the peripheral edge of the upper surface 310 of the main body plate portion 31 in a plan view. In the first embodiment, as shown in Figure 3, the gripping portion 4 is formed in the center of the peripheral edge along the short side 313 of the main body plate portion 31. At least one pair of gripping portions 4 is provided.

The grip portion 4 has an opening 40 that opens toward the center in a plan view, and a bottomed finger insertion space 41 inside which a finger can be inserted. A protruding piece 34 that protrudes above the top surface 310 of the main body plate portion 31 is provided on the top surface 310. The grip portion 4 is provided on this protruding piece 34.

The protruding strip 34 includes an upright piece 341, a horizontal piece 342, an end piece 343, and a rib 344. The upright piece 341 stands upright from the upper surface 310. The upright piece 341 forms the bottom wall of the finger insertion space 41. As shown in Figure 4A, the angle θ1 that the upright piece 341 makes with respect to the upper surface 310 is not particularly limited, but the upright piece 341 is inclined toward the center of the main body plate portion 31 in a plan view.

As shown in FIG. 3 , a horizontal piece 342 extends from the upper end of the upright piece 341 toward the center of the main body plate portion 31 in a plan view. The width of the horizontal piece 342 is constant, and the end edge 3421 is linear. In this embodiment, the width of the horizontal piece 342 is shorter than the length of the upright piece 341 in the vertical direction. End pieces 343 are formed at the longitudinal ends of the upright piece 341 and the horizontal piece 342.

End piece 343 stands upright from top surface 310. As shown in FIG. 4B , the angle θ2 that end piece 343 makes with top surface 310 is not particularly limited, but end piece 343 is inclined toward the center of short side 313 of main body plate 31. As shown in FIG. 3 , the upper end of end piece 343 is connected to the end of horizontal piece 342 facing short side 313, and the outer end of end piece 343 in plan view is connected to the end of upright piece 341 facing short side 313. The main body plate 31, upright piece 341, horizontal piece 342, and end piece 343 surround and form finger insertion space 41 that opens toward the center in plan view.

Finger insertion space 41 is also provided with a reinforcing rib 344. Rib 344 is provided in the center of protrusion 34 in the direction of short side 313. Rib 344 rises from top surface 310, with the upper end of rib 344 connected to horizontal piece 342, and the outer end of end piece 343 in a plan view connected to upright piece 341. By providing rib 344, when a user holds grip portion 4 in their hand, horizontal piece 342 is less likely to bend, and upright piece 341 and horizontal piece 342 are less likely to twist, preventing deformation. If horizontal piece 342 is short, when a user hooks their finger on grip portion 4 to lift lid 3, the finger's gripping margin becomes shorter. If grip portion 4 deforms, the finger may come off grip portion 4, causing lid 3 to fall. However, by providing the rib 344, even if the width of the horizontal piece 342 is short, the grip portion 4 is less likely to deform, making it less likely that your fingers will come off the grip portion 4 and the lid 3 will fall off.

The grip portion 4 is also provided with drainage holes 42. In the first embodiment, the drainage holes 42 are formed in the upstanding piece 341 as through-holes that penetrate the upstanding piece 341 in an inward and outward direction in a plan view. The drainage holes 42 are formed in the center of the short side 313 of each half of the upstanding piece 341 defined by the ribs 344. The provision of the drainage holes 42 allows water that has entered the finger insertion space 41 to be drained.

The gripping portion 4 is composed of a protruding piece 34 having a finger insertion space 41 inside. When lifting the lid 3 placed on the top container 2 of the stack, the user inserts their finger into the finger insertion space 41 through the opening 40 and grasps the protruding piece 34 (mainly the horizontal piece 342) that serves as the gripping portion 4, making it easier to grasp the lid 3 or hook their finger on it.

For example, when a user attempts to remove the lid 3 of a lidded container 1 placed on the floor at their feet from the container 2, they can insert their fingers from above through the opening 40 of the handle 4 into the finger insertion space 41, grasp the horizontal piece 342 of the handle 4, and lift the lid 3 to remove it from the container 2.

When a user attempts to remove the lid 3 from the container 2 of a lidded container 1 that is located high up, such as on an overhead shelf, the user first raises their arm and moves their hand from below toward the top of the lid 3. Next, the user inserts the fingertips of one or more of the index finger, middle finger, ring finger, and little finger through the upper side of the horizontal piece 342 and into the finger insertion space 41 through the opening 40, and grasps the horizontal piece 342 with the fingers. Here, because the finger insertion space 41 opens toward the center in a plan view, it is easy to insert the fingertips of the fingers (index finger, middle finger, ring finger, or little finger) that have passed through the upper side of the horizontal piece 342 from the outside to the inside of the lidded container 1 in a plan view into the finger insertion space 41 through the opening 40 to grasp the handle portion 4 or hook the fingers.

Next, lift the horizontal piece 342 grasped with the fingers and move the hanging piece 32 upward to remove it from the container 2. Next, insert your thumb into the gap between the bottom end of the hanging piece 32 and the top end of the container 2, hook the thumb onto the bottom end of the hanging piece 32, and grasp the horizontal piece 342, the upright piece 341, and the hanging piece 32 with your entire hand. This allows you to grasp the lid 3 with your hand, remove it from the container 2, and lower it. The worker can then remove the contents from the container 2.

Next, the second embodiment will be described with reference to Figure 5. Note that the second embodiment is largely the same as the first embodiment. Therefore, explanations that overlap with the first embodiment will be omitted.

In the first embodiment, the end edge 3421 of the horizontal piece 342 was straight (see Figure 3). In contrast, in the horizontal piece 342 of the second embodiment, the width (length in the direction of the long side 312) is greatest at the center in the direction along the short side 313, and the end edge 3421 is curved so that the center in the direction along the short side 313 bulges most toward the center in a plan view. This makes it easier for the user to hook their finger on the horizontal piece 342.

Next, the third embodiment will be described with reference to Figure 6. Note that the third embodiment is largely the same as the second embodiment. Therefore, explanations that overlap with the second embodiment will be omitted.

In the second embodiment, the horizontal piece 342 is widest at the center along the short side 313, and the end edges 3421 are curved so that they bulge most at the center along the short side 313. In contrast, in the third embodiment, the end edges 3421 are wavy in the direction along the short side 313. In other words, the width of the horizontal piece 342 changes so that it repeatedly increases and decreases in the direction along the short side 313. This makes it easier for the user to hook their fingers onto the horizontal piece 342, compared to horizontal pieces 342 whose end edges 3421 are straight (see Figure 3).

Next, the fourth embodiment will be described with reference to Figure 7. Note that the fourth embodiment is largely the same as the first embodiment. Therefore, explanations that overlap with the first embodiment will be omitted.

In the first embodiment, the grip portion 4 is provided on the protruding piece 34 and has an opening 40 that opens toward the center in a plan view, with a bottomed finger insertion space 41 inside where a finger can be inserted (see Figure 3). In contrast, the grip portion 4 of the fourth embodiment is provided on the recess-forming portion 35 and has an opening 40 that opens upward, with a bottomed finger insertion space 41 inside where a finger can be inserted. The recess-forming portion 35 includes a vertical piece 351, a bottom piece 352, and a vertical piece 353. The opening 40 is formed in a portion of the main body plate portion 31. The vertical piece 351 hangs down from the main body plate portion 31 at a portion that is outer in a plan view than the portion of the main body plate portion 31 where the opening 40 is formed. Furthermore, the vertical piece 353 hangs down from the main body plate portion 31 at the inner end of the opening 40 in a plan view. The lower ends of the vertical piece 351 and the vertical piece 353 are connected by the bottom piece 352. The finger insertion space 41 is formed by the vertical piece 351, bottom piece 352, vertical piece 353, and a part of the main body plate portion 31 that forms the grip portion 4.

In the first embodiment, when a user attempts to remove the lid 3 that is in a high position, the user moves their hand to the upper side of the lid 3 and inserts the fingertips of one or more of their index finger, middle finger, ring finger, and little finger through the top of the horizontal piece 342 and into the finger insertion space 41 from the opening 40 facing outward in a plan view, thereby grasping the horizontal piece 342. This requires the fingers grasping the horizontal piece 342 (index finger, middle finger, ring finger, little finger) to bend back 180 degrees.

In contrast, the grip portion 4 of the fourth embodiment has an opening 40 that opens upward, so the hand is moved to the upper side of the lid 3 and the fingertips of one or more of the index finger, middle finger, ring finger, and little finger are inserted downward through the opening 40 into the finger insertion space 41 to grasp the grip portion 4. As a result, the fingers grasping the grip portion 4 (index finger, middle finger, ring finger, little finger) do not need to bend back 180 degrees, but can be bent by 90 degrees, making it easier to hook the fingers.

In addition, the upper end of the grip portion 4 is at the same height as the upper surface portion 310, so the grip portion 4 does not protrude from the upper surface portion 310.

Next, the fifth embodiment will be described with reference to Figure 8. Note that the fifth embodiment is largely the same as the first embodiment. Therefore, explanations that overlap with the first embodiment will be omitted.

In the first embodiment, the grip portion 4 had a bottomed finger insertion space 41 inside that opened toward the center in a plan view and into which a finger could be inserted (see Figures 1 to 3). In contrast, the grip portion 4 of the fifth embodiment has a finger insertion hole 43 that penetrates vertically through the peripheral edge of the top surface 310 of the main body plate portion 31 in a plan view and into which a finger can be inserted.

The grip portion 4 is provided on the protrusion component 36. The protrusion component 36 includes a vertical piece 361, a horizontal piece 362, and a vertical piece 363. An opening 40 is formed in part of the main body plate portion 31. The vertical piece 361 stands upright from the main body plate portion 31 at a portion that is outer in plan view than the portion where the finger insertion hole 43 is formed. The vertical piece 363 stands upright from the main body plate portion 31 at an end that is inner in plan view than the portion where the finger insertion hole 43 is formed. The lower ends of the vertical piece 361 and the vertical piece 363 are connected by the horizontal piece 362. The finger insertion hole 43 is formed in part of the horizontal piece 362.

The grip portion 4 of the fifth embodiment has a finger insertion hole 43 that penetrates vertically. Therefore, by moving the hand to the upper side of the lid 3 and inserting the fingertips of one or more of the index finger, middle finger, ring finger, and little finger downward through the finger insertion hole 43 into the finger insertion space 41, the grip portion 4 can be grasped with the fingers. Therefore, the fingers grasping the grip portion 4 do not need to bend back 180 degrees; they can be bent by 90 degrees, making it easier to hook the fingers.

Furthermore, there is no need to provide a bottomed finger insertion space 41 as in the first embodiment; instead, it is sufficient to provide a finger insertion hole 43, which is a through-hole, making it easier to mold the lid 3.

Next, the sixth embodiment will be described with reference to Figure 9. Note that the sixth embodiment is largely the same as the first embodiment. Therefore, explanations that overlap with the first embodiment will be omitted.

In the first embodiment, the grip portion 4 had a bottomed finger insertion space 41 inside that opened toward the center in a plan view and allowed for the insertion of a finger (see Figures 1 to 3). In contrast, the grip portion 4 of the sixth embodiment has a finger insertion hole 43 that penetrates toward the center in a plan view on the peripheral edge of the top surface 310 of the main body plate portion 31, allowing for the insertion of a finger.

The grip portion 4 of the sixth embodiment differs from the first embodiment in that it does not include a horizontal piece 342. This eliminates the need to provide a bottomed finger insertion space 41 as in the first embodiment, and only requires the provision of a through-hole finger insertion hole 43, making it easier to mold the lid 3.

Next, the seventh embodiment will be described with reference to Figure 10A. Note that the seventh embodiment is largely the same as the first embodiment. Therefore, explanations that overlap with the first embodiment will be omitted.

The grip portion 4 of the seventh embodiment is configured with a rib 37 that protrudes from the upper surface portion 310. The rib 37 is inclined toward the center of the main body plate portion 31 in a plan view. A triangular rib 38 for reinforcement is connected to the outer side of the rib 37 in a plan view of the main body plate portion 31.

This makes it easy for a user to grasp the rib 37 (grip portion 4) with their hand raised above the lid 3 or hook the rib 37 with their finger when attempting to remove the lid 3 that is in a high position.

Next, the eighth embodiment will be described with reference to Figure 10B. Note that the eighth embodiment is largely the same as the seventh embodiment. Therefore, explanations that overlap with the seventh embodiment will be omitted.

The grip portion 4 of the eighth embodiment is composed of a T-shaped rib 39 that protrudes from the top surface 310. This makes it easy for a user to grasp the rib 39 (grip portion 4) with their hand raised above the lid 3 or hook the rib 37 with their fingers when attempting to remove the lid 3 that is in a high position.

Next, we will explain some modified examples. Note that the following modified examples may be applied to any of the first through eighth embodiments to which they can be applied.

The shape of the container 2 does not have to be a rectangular (rectangular or square) box, and may be a box shape of, for example, a pentagon or a polygon with more than 5 sides, and is not particularly limited. Furthermore, the container 2 does not have to be foldable. Furthermore, the material of the container 2 does not have to be resin, and may be, for example, wood, wood-based material, metal, etc., and is not particularly limited. Furthermore, openings or holes may be formed in parts of the bottom plate 21 and side plates 22 of the container 2.

The material of the lid 3 does not have to be resin, and may be, for example, wood, wood-based material, metal, etc., and is not particularly limited. The planar shape of the main body plate portion 31 does not have to be rectangular, and may be, for example, a box shape such as a pentagon or a polygon with more than five sides, and is not particularly limited. The planar shape of the main body plate portion 31 is preferably the same as the planar shape of the bottom plate 21, but does not necessarily have to be the same as the planar shape of the bottom plate 21.

The gripping portion 4 does not have to be formed on the peripheral portion along the short side 313 of the main body plate portion 31; for example, it may be formed on the peripheral portion along the long side 312 of the main body plate portion 31 or on a corner of the main body plate portion 31. The gripping portion 4 may be formed on each of all long sides 312 and short sides 313 of the main body plate portion 31.

The grip portion 4 does not have to be provided on the protruding piece 34.

The angle θ1 that the standing piece 341 makes with respect to the upper surface portion 310 is not limited; for example, the standing piece 341 may stand perpendicular to the upper surface portion 310. Furthermore, the length of the standing piece 341 in the vertical direction or the length in the longitudinal direction is not particularly limited.

The height of the horizontal piece 342 from the top surface 310 and the width of the horizontal piece 342 are not particularly limited.

The angle θ2 that the end piece 343 makes with respect to the upper surface portion 310 is not limited; for example, the end piece 343 may stand perpendicular to the upper surface portion 310.

The location and number of ribs 344 are not limited, and ribs 344 do not have to be provided.

The location and number of drainage holes 42 are not limited, and drainage holes 42 do not have to be provided.

When a user attempts to remove the lid 3 from the container 2 of a lidded container 1 that is located high up, such as on an overhead shelf, the user can move their hand to the top of the lid 3, insert their thumb into the finger insertion space 41 through the opening 40, and grasp the horizontal piece 342.

As is clear from the above-described embodiments and variations, the first aspect is a lid 3 that closes the upper end opening 20 of a box-shaped container 2 that opens upward. The lid 3 includes a main body plate portion 31. A grip portion 4 is provided on the peripheral edge of the top surface portion 310 of the main body plate portion 31 in a plan view. The grip portion 4 opens toward the center or upward in a plan view and has a bottomed finger insertion space 41 inside where a finger can be inserted.

With the lid 3 of the first aspect, when a user attempts to remove the lid 3 from the container 2 of a lidded container 1 that is located high above the user's head, the user can easily insert the tip of a finger (index finger, middle finger, ring finger, or little finger) that has passed over the top of the lid 3 from the outside to the inside of the lidded container 1 in a plan view into the finger insertion space 41, making it easy to hook the finger on the grip portion 4 or grasp the grip portion 4 with the hand.

The second aspect is a lid 3 that closes the top opening 20 of a box-shaped container 2 that opens upward. The lid 3 includes a main body plate portion 31. A grip portion 4 is provided on the peripheral edge of the top surface portion 310 of the main body plate portion 31 in a plan view, and has a finger insertion hole 43 that penetrates centrally or vertically in a plan view and through which a finger can be inserted.

With the lid 3 of the second aspect, when a user attempts to remove the lid 3 from the container 2 of a lidded container 1 that is located high above the user's head, the user can easily insert the tip of a finger (index finger, middle finger, ring finger, or little finger) that has passed over the lid 3 from the outside to the inside of the lidded container 1 in a plan view into the finger insertion space 41, making it easy to hook the finger on the grip portion 4 or grasp the grip portion 4 with the hand. Furthermore, since there is no need to provide a bottomed finger insertion space 41 and it is sufficient to simply provide a finger insertion hole 43, which is a through-hole, the lid 3 can be easily molded.

The third aspect can be achieved by combining the first or second aspect. A protruding piece 34 that protrudes above the upper surface 310 of the main body plate portion 31 is provided on the upper surface 310. A grip portion 4 is provided on the protruding piece 34.

According to the third aspect, the grip portion 4 is easy to form.

The fourth aspect can be achieved by combining it with any of the first to third aspects. In the fourth aspect, a drainage hole 42 is provided in the grip portion 4.

According to the fourth aspect, water that has entered the finger insertion space 41 can be expelled.

The fifth aspect can be realized by combining it with any of the first to fourth aspects. In the fifth aspect, the main body plate portion 31 has step portions 315, 317 with different upper and lower surface heights at different positions in a plan view.

According to the fifth aspect, the main body plate portion 31 is less likely to bend or twist, i.e., less likely to deform.
