Description

TECHNICAL FIELD The present invention relates to a container with a lid.

2. Description of the Related Art Conventionally, containers with lids, such as trash cans, have been known that can seal the inside of the container so as to contain the odor of the contents inside the container and prevent the contents from leaking out of the container. This container with a lid includes a container body having an opening, a lid for opening and closing the opening of the container body, and a container body and the lid sandwiched between the container body and the lid. It has a packing for sealing, and an engagement mechanism that engages one of the container body and the lid with the other to hold the lid closed with respect to the container body.

The lidded container described in Patent Document 1 includes, as an engaging mechanism, a hinge portion that connects the container body and the lid, and an engaging portion that engages with the container body to hold the lid in a closed state. have. In this trash can, the packing is housed in an annular groove provided in the lid so that the entire packing fits in the depth direction of the groove. The container main body is provided with an annular projection for holding the packing between itself and the lid. When the lid of the trash can is closed and the engaging portion is engaged with the container body, the container body and the lid are sealed with the packing sandwiched therebetween.

JP 2018-090364 A

In the trash can disclosed in Patent Document 1, the packing is sandwiched from both sides by the inner side surfaces of the groove provided in the lid. Therefore, lateral deformation is restricted by the inner surface of the groove of the packing sandwiched between the lid and the ridge. In addition, the deformation of the packing is further restricted at the portion distant from the hinge portion and the engaging portion, since the force with which the ridge is pinched is smaller than at the portion near the hinge portion or the engaging portion. For this reason, in the trash can disclosed in Patent Document 1, there is a portion where it is difficult for the ridges and the packing to come into close contact with each other, and there is a risk that the container body and the lid cannot be sufficiently sealed.

In addition, as described above, since the packing is housed in the groove provided in the lid so that the entire packing can be accommodated in the groove, it is difficult to pick it up or hook it with a finger, making it difficult to remove the packing from the groove. There is also the problem of

The present invention has been made in view of such problems, and the sealing member can sufficiently seal the space between the container body and the lid, and the sealing member can be easily removed. An object of the present invention is to provide a container with a lid.

As a result of various studies, the inventors of the present invention have found that the above objects are achieved by the following inventions.

A container with a lid according to one aspect of the present invention comprises a container body having an opening, a lid capable of opening and closing the opening of the container body, and a first body of either the container body or the lid. provided in the container body and extending in a predetermined direction and opening in one direction in the depth direction; A sealing member capable of sealing between the container body and the lid, and holding the container body and the lid in an engaged state with the sealing member sandwiched between the groove and the projection. and an engaging mechanism, wherein the sealing member has an accommodated portion accommodated in the groove portion and a deformable portion provided outside the groove portion in a depth direction, the sealing member extends in the predetermined direction and has a pair of side walls facing each other in a lateral direction perpendicular to the predetermined direction and the depth direction; The accommodated portion has a reinforcing portion that connects and reinforces the side walls in the lateral direction, and the deformation portion includes the pair of side walls, the first bottom plate, and the reinforcing portion. It has a hollow shape in which a closed space is formed between the parts.

In the lidded container, the deformation portion of the sealing member is open in the width direction of the groove, so that the deformation portion can be easily deformed when the sealing member is sandwiched between the groove and the projection. As a result, it is difficult for the protrusion and the sealing member to form a portion that is difficult to adhere to, and the space between the container body and the lid can be sufficiently sealed. In addition, since the deformable portion is provided outside the groove, it is easy to pick up and the sealing member can be easily removed from the groove. Furthermore, the deformable portion is more likely to be deformed than when it is solid, and it is possible to make it more difficult for the protruding portion and the sealing member to come into close contact with each other.

In the lidded container described above, the first body has an outer wall extending from the outer edge of the groove toward the second body, and the outer wall extends from the outer edge of the groove to the end face of the deformed portion, or It may extend to the second body side from the end face to support the deformable portion from the outside, and the deformable portion may be open to the inside.

In this aspect, the deformation portion is supported by the outer wall from the outside, and the deformation direction of the sealing member sandwiched between the projections can be limited to the inside. As a result, it is possible to stably seal between the container body and the lid, compared to the case where the deformation direction of the deformable portion varies between the inside and the outside.

In the lidded container described above, the protrusions may sandwich the deformable portion inside a widthwise center of the deformable portion.

In this aspect, the radius of rotation of the deformable portion about the outer portion of the deformable portion that is sandwiched between the protrusions is increased, and the portion sandwiched between the protrusions is closer to the end of the deformable portion in the deformation direction. . Therefore, the deformable portion can be deformed with a smaller force than when the deformable portion is sandwiched outside the center of the deformable portion in the width direction, and the container body and the lid can be more stably sealed. can be done.

In the lidded container described above, the deformable portion may have a width wider than that of the groove.

In this aspect, the deformation portion can be deformed with a smaller force than when the width of the deformation portion is equal to or less than the width of the groove portion, and the container body and the lid can be more stably sealed.

In the lidded container described above, the accommodated portion may be solid.

In this aspect, since the rigidity of the accommodated portion is greater than when the accommodated portion is hollow, the accommodated portion can be easily accommodated in the groove portion.

In the lidded container described above, the accommodated portion may further include a second bottom plate connecting the other end portions of the side walls to each other in the horizontal direction.

In the lidded container described above, a tapered portion may be formed at an end of the accommodated portion opposite to the deformed portion.

In this aspect, the portion to be accommodated can be accommodated in the groove more easily.

In the lid-equipped container, the first body may be the lid, and the second body may be the container body.

In this aspect, the container body can have a simple structure in which there is no groove and the protrusion is provided, and the container body can be easily cleaned.

In the lid-equipped container described above, the engaging mechanism includes a hinge portion that connects the lid to the container body so as to be rotatable about a predetermined axis so as to close the opening from the open side; and an engaging portion that is provided on the container body and engages with the lid body so as to hold the lid body in a closed state with respect to the container body.

In this aspect, the lid is connected to the container body by the hinge portion, and the container body and the lid can be engaged with each other by at least one engaging portion. Therefore, the space between the container body and the lid can be easily sealed.

According to the present invention, it is possible to provide a lidded container in which the sealing member can sufficiently seal the space between the container body and the lid, and the sealing member can be easily removed.

It is A pair of insertion holes 21d into which protrusions 6a of the cover 6, which will be described later, can be inserted are provided on both sides of the second through hole 21b in the X direction.

(biasing unit)
The biasing unit 5 includes a first member 51 attached to the container body 2, a second member 52 connected to the first member 51 so as to be rotatable with respect to the first member 51, and a first and a biasing member 53 that biases the second member 52 against the member 51 in the opening direction. The second member 52 is rotatable with respect to the first member 51 around a second axis parallel to the first axis, which is the rotation axis of the lid 3 (parallel to the X direction).

As shown in FIG. 4, the first member 51 has a bottom surface and three side walls extending upward from the bottom surface. Of the three side walls, two side walls facing each other in the X direction are provided with a first shaft 51a extending outward in the X direction to which the second member 52 can be attached, and a biasing member 53 extending inward in the X direction. An attachable second shaft 51b is provided. Both the central axes of the first shaft 51a and the second shaft 51b coincide with the second axis.

Of the three side walls, the side wall perpendicular to the Y direction of the first member 51 is formed with an arm portion 51d functioning as a plate spring with grooves provided around the side wall. The arm portion 51d is rotatable in the Y direction about its upper end, and the lower end of the arm portion 51d can be engaged with the first through hole 21c and the second through hole 21b of the first accommodating portion 21. projection 51e is provided. The protrusion 51e has a shape that widens downward from above. In addition, concave portions 51c are provided on both sides in the X direction of the lower ends of the side walls perpendicular to the Y direction so that protrusions 6a of the cover 6, which will be described later, can escape.

The second member 52 has a trapezoidal body portion 52a and a pair of side walls 52b extending from both ends of the bottom of the body portion 52a. 52 d of arm insertion holes which receive the arm of the biasing member 53 are provided in the X direction center of the lower bottom of the main-body part 52a. The side wall 52 b is provided with a shaft hole 52 c that can be attached to the first shaft 51 a of the first member 51 .

The biasing member 53 has a structure in which two torsion coil springs are combined. Specifically, two coil portions 53b arranged side by side in the X direction, an arm 53a provided inside each coil portion 53b in the X direction and connecting each coil portion 53b, and an arm 53a connecting each coil portion 53b in the X direction It has two arms 53c connected to the outside. The arm 53c is provided with a first convex portion 53d and a second convex portion 53e smaller than the first convex portion 53d, which are formed by bending respective ends. Under no load, the opening angle between the arms 53a and 53c is greater than 180°.

A method of assembling the biasing unit 5 is as follows. First, the coil portion 53b of the biasing member 53 is attached to each of the second shafts 51b of the first member 51 . At this time, the biasing member 53 is arranged so that the arm 53a is positioned outside the first member 51 and the arm 53c is positioned inside the first member. Next, the arm 53a is rotated with respect to the first member 51 in a direction in which the second member 52 is closed from a state in which no load is applied, and the arm insertion hole 52d of the second member 52 is opened with an opening angle of about 180°. , and then the shaft hole 52 c is attached to the first shaft 51 a of the first member 51 . Thereby, the biasing unit 5 is completed. In the urging unit 5 , the urging member 53 is in a state of receiving a load in the direction of closing the second member 52 with respect to the first member 51 . The member 52 is biased in the opening direction.

Next, a method for attaching the biasing unit 5 to the container body 2 will be described. First, as shown in FIG. 7, the biasing unit 5 is inserted from the side of the second member 52 through the opening 21a on the lower side of the first accommodating portion 21. Then, as shown in FIG. When the urging unit 5 is moved upward, the lower end of the side wall facing the +Y direction of the first accommodating portion 21 and the protrusion 51e of the first member 51 come into contact with each other, and the arm portion 51d of the first member 51 is gradually Rotate inward. When the urging unit 5 is further moved upward, as shown in FIGS. 8 and 11, the entire projection 51e is accommodated in the second through hole 21b of the first accommodation portion 21, and the arm portion 51d is extended outward. Rotate. In this state, even if the urging unit 5 is pushed downward, the lower surface of the projection 51e engages with the lower surface of the second through hole 21b, and the arm portion 51d cannot rotate, so the urging unit 5 moves downward. I can't.

Thus, the biasing unit 5 is arranged in the second position. At the second position, the first shaft 51 a and the second shaft 51 b of the first member 51 are housed in the first housing portion 21 . That is, the second axis of the biasing unit 5 is housed in the first housing portion 21 .

When the biasing unit 5 arranged at the second position is further moved upward, the upper surface of the second through hole 21b and the protrusion 51e come into contact with each other, and the arm portion 51d of the first member 51 gradually moves inward. Rotate. When the urging unit 5 is further moved upward, as shown in FIG. 12, the entire projection 51e is accommodated in the first through hole 21c of the first accommodation portion 21, and the arm portion 51d rotates outward. . Even in this state, even if the urging unit 5 is pushed downward, the lower surface of the projection 51e engages with the lower surface of the first through hole 21c, and the arm portion 51d cannot rotate, so the urging unit 5 moves downward. I can't. At this time, as shown in FIG. 18(a), the protrusion 51f extending in the -Y direction from the lower end of the first member 51 of the biasing unit 5 engages the inner wall 21i of the first accommodating portion 21. Therefore, the biasing unit 5 cannot move upward any more.

Thus, the biasing unit 5 is arranged in the first position. At the first position, the second axis of the biasing unit 5 is exposed to the outside. The second member 52 is opened with respect to the first member 51 by the biasing force of the biasing member 53 when no force is applied.

When the biasing unit 5 is arranged at the second position, the user pushes the protrusion 51e through the second through-hole 21b, causing the biasing unit 5 to be extracted from the lower opening 21a. There is a risk. Therefore, in the present embodiment, as shown in FIG. 9, by attaching a cover 6 that closes the second through hole 21b to the first accommodating portion 21, the urging unit 5 arranged at the second position can be pulled out. are preventing.

As shown in FIGS. 10 and 12, the cover 6 has a plate-like main body (no reference numerals) and projections 6a at both ends of the main body in the X direction. It is When the projection 6a is inserted into the insertion hole 21d after the urging unit 5 is arranged at the second position, the barb 6b engages with the inner surface of the first accommodating portion 21 and the cover 6 is fixed. This prohibits access to the projection 51e through the second through hole 21b. At this time, the portion of the first member 51 facing the projection 6a is provided with a recess 51c, which allows the projection 6a to escape and prevents the projection 6a and the first member 51 from interfering with each other.

The first housing portion 21 is provided with a protective portion 21e that protrudes in the +Y direction so as to surround the main body portion of the cover 6 . As shown in FIGS. 10 and 11, the protruding height of the protective portion 21e is substantially the same as the thickness of the main body of the cover 6, so that fingers and tools are less likely to be caught around the main body of the cover 6, and the cover 6 can be easily removed. cannot be removed.

Here, when producing containers 1 with lids of different sizes, the first member 51 and the second member 52 of the biasing unit 5 can be used in common. , it is necessary to use a biasing member 53 having a biasing force corresponding to its weight. In such a case, the biasing force of the biasing member 53 can be distinguished by the size of the convex portion provided at the end of the arm 53c. In the biasing member 53 having a certain biasing force, as shown in FIGS. 4 and 5, the second convex portion 53e in the +X direction is smaller than the first convex portion 53d in the -X direction, and another In the biasing member 53 having the biasing force, as shown in FIG. 6, the biasing force is distinguished by making the fourth convex portion 53g in the −X direction smaller than the third convex portion 53f in the +X direction. can do. Further, as shown in FIGS. 5 and 6, depending on the size of the lidded container 1, the first convex portion 53d can be accommodated in the portion surrounded by the first accommodating portion 21 of the container body 2. A groove 21f or a groove 21g capable of accommodating the third convex portion 53f is provided. 5 and 6, the +Y direction side wall of the first accommodating portion 21 is omitted.

As a result, when the biasing member 53 having a biasing force corresponding to the size of the lidded container 1 is used, when the biasing unit 5 is attached, as shown in FIGS. The third convex portion 53f is accommodated in the first convex portion 53d and the groove 21g, and the respective convex portions do not hinder the mounting of the urging unit 5. As shown in FIG. On the other hand, when the biasing member 53 having a biasing force not corresponding to the size of the lidded container 1 is used, for example, when the biasing member shown in FIG. 6 is used for the container body 2 of FIG. The protruding portion 53f collides with the lower end of the side wall 21h, the biasing unit 5 cannot be attached, and it can be noticed that the biasing member is in error.

In the second housing portion 31, the second member 52 of the biasing unit 5 contacts only the top plate 3a of the lid 3, and the portion of the second member 52 other than the portion facing the top plate 3a is always In this state, there is a gap with respect to the second housing portion 31 . When the biasing unit 5 biases the lid 3, the portion of the second member 52 facing the top plate 3a contacts the top plate 3a, and the biasing force is transmitted to the lid 3 only from this portion. . In this embodiment, the second member 52 extends from the outside to the inside of the area surrounded by the groove 32a, and the second member 52 can be made sufficiently long. Therefore, the urging force in the opening direction can be sufficiently transmitted from the second member 52 to the lid 3 , and the urging unit 5 can reliably open the lid 3 .

Further, in this embodiment, the pair of lid mounting portions 22 are provided so as to sandwich the biasing unit 5, and the lid 3 can be supported on both sides of the biasing portion by the biasing unit 5.

The annular packing 7 is sandwiched between the lid 3 and the container body 2 when the lid 3 is closed, and seals between the lid 3 and the container body 2 . As shown in FIGS. 15, 23, etc., the packing 7 is attached over the entire circumference of the groove 32a of the lid 3. As shown in FIG.

The packing 7 is made of elastic rubber such as silicon rubber, resin, or the like, and as shown in FIGS. and a deformed portion 7b. The deformable portion 7b is supported from the outside by the outer wall 32b provided on the outer edge of the groove portion 32a.

The accommodated portion 7a has a dimension that makes contact with the inner side of the groove portion 32a. In this embodiment, the accommodated portion 7a is hollow, and has a reinforcing portion 7f that joins the inner wall and the outer wall of the accommodated portion 7a to reinforce the accommodated portion 7a.

The deformation portion 7b is also hollow and has a width wider than that of the groove portion 32a. The deformation portion 7b includes an extension portion 7e extending along the lower surface of the inner wall of the groove portion 32a, an inner wall 7d extending from the inner end portion of the extension portion 7e outward in the depth direction of the groove portion 32a, and the depth of the groove portion 32a of the inner wall 7d. It has a bottom plate 7c extending outward from the outer end in the vertical direction, and an outer wall connected to the end of the bottom plate 7c.

As shown in FIG. 21(c), when the lid body 3 is closed, the protrusions 24 provided on the container body 2 sandwich the deformable portion 7b inside the center of the deformable portion 7b in the width direction. there is

A tapered portion 7g is formed at the opposite end of the accommodated portion 7a from the deformed portion 7b.

(Regarding the effect of changing the position of the biasing unit)
When the biasing unit 5 is arranged at the first position, the first shaft 51 a , i.e., the second rotation shaft is exposed above the first housing portion 21 and is positioned at the first position relative to the first member 51 . The second member 52 is rotatable, and biasing force can be transmitted from the second member 52 to the lid body 3 .

At the second position, the biasing unit 5 is arranged below the first position. Therefore, when the lid 3 and the container body 2 are separated during transportation, the biasing unit 5 is moved to the second position. By arranging at the first position, damage to the urging unit 5 can be suppressed as compared with the case where it is arranged at the first position. Moreover, at the second position, the second axis is housed in the first housing portion 21, so that the second axis can also be protected. Furthermore, if the urging unit 5 is arranged at the second position, damage to the urging unit 5 can be suppressed without removing the urging unit 5 from the container body 2 . Loss can also be suppressed.

When the urging unit 5 is placed at the second position, even if the container bodies 2 are stacked as shown in FIG. The two first accommodation portions 21 are separated from each other, and damage to the urging unit 5 can be suppressed.

The first housing portion 21 can house the biasing unit 5 so that the upper end portion of the biasing unit 5 arranged at the second position, that is, the tip portion of the second member 52 is exposed to the outside. preferable. In this case, the distal end portion of the second member 52 of the urging unit 5 arranged at the second position can be easily pinched or hooked with a finger, so that the urging unit 5 can be placed in the second posture. can be easily moved from the position to the first position.

(opening/closing operation)
As the opening/closing operation of the lid 3, first, the operation from immediately after the lid 3 is attached to the container body 2 until it is closed will be described.

FIG. 21 is a cross-sectional view from immediately after attaching the lid to the container body until it is closed, and FIG. 3(b) shows a state in which the opening angle of the cover is 70°, and FIG. 3(c) shows a state in which the cover is closed.

Immediately after the lid 3 is attached to the container body 2, as shown in FIG. Rotation is impeded. From this state, when a certain amount of force is applied in the direction of closing the lid 3, the barrier 37 gradually pushes down the protrusion 23, and the lower end of the barrier 37 climbs over the protrusion 23 as shown in FIG. 21(b). After that, if a force exceeding the biasing force of the biasing unit 5 is applied in the closing direction of the lid 3, the lid 3 can be closed as shown in FIG. 21(c). FIG. 13 shows the upper portion of the lidded container 1 with the lid 3 closed, viewed from the back.

When the lid 3 is closed, as shown in FIG. 22(a), the projection 33 provided on the lid 3 is engaged with the engaging member 4 provided on the container body 2, and the lid 3 is closed. is held to

When closing the lid 3 in the open state, when the lid 3 is pushed down, the upper end of the engaging member 4 and the vertical plate 33b of the projection 33 come into contact with each other. The side wall 4b of the engaging member 4 rotates in the -Y direction. When the lid body 3 is completely closed, the protrusion 33 is fitted into the lateral groove 4c and the longitudinal groove 4d of the engaging member 4, and the engaging member 4 is biased by the biasing member 4a to rotate the side wall 4b in the +Y direction. . In this state, even if the lid 3 is urged in the opening direction by the urging unit 5, the lid 3 does not open because the protrusion 33 and the engaging member 4 are engaged.

When the engaging member 4 is pushed down with the lid 3 closed, the side wall 4b rotates in the -Y direction as shown in FIG. The urging force of the unit 5 enables the lid 3 to rotate in the opening direction. When the cover 3 in the closed state is opened only by the biasing force of the biasing unit 5, the lower end of the barrier 37 cannot get over the protrusion, so the cover 3 rotates at the opening angle shown in FIG. 21(b). stops.

(Action of packing)
Next, the action of the packing in the lidded container of this embodiment will be described.

When the lid 3 is closed to the container body 2, the container body 2 and the lid 3 are held with the packing 7 sandwiched between the protrusion 24 and the groove 32a by the engaging mechanism. At this time, the deformed portion 7b of the packing 7 deforms and comes into close contact with the projection 24, thereby sealing the space between the container body 2 and the lid 3. As shown in FIG.

In this embodiment, the deformed portion 7b of the packing 7 is supported from the outside by the outer wall 32b and is open to the inside in the width direction of the groove portion 32a. Therefore, when the packing 7 is sandwiched between the groove portion 32a and the projection portion 24, the deformation direction of the deformation portion 7b is limited to the inside. As a result, compared to the case where the deforming direction of the deformable portion 7b varies inwardly and outwardly, it is less likely that the protrusion 24 and the packing 7 will be in close contact with each other, and the container body 2 and the lid 3 will be stabilized. can be sealed. In addition, since the deformation portion 7b is provided outside the groove portion 32a, it is easy to pick up and the packing 7 can be easily removed from the groove portion 32a. In addition, the outer wall 32b makes it more difficult for the contents and their odors to leak out of the container.

In the present embodiment, the deformable portion 7b is hollow and deforms more easily than when it is solid.

Further, when the deformable portion 7b is sandwiched between the projecting portions 24, the deformable portion 7b rotates about the outer portion of the deformable portion 7b supported by the outer wall 32b as a central axis. In this embodiment, the outer wall of the deformable portion 7b is thicker than the bottom plate 7c, the inner wall 7d, and the extension portion 7e, and is less deformable than these portions, so that the central axis of rotation of the deformable portion 7b is less likely to be shaken. Further, in the present embodiment, as shown in FIG. 21(c) and the like, the protrusions 24 sandwich the deformed portion 7b inside the center of the deformed portion 7b in the width direction, and the deformed portion 7b is located between the grooves 32a. It has a wider width than the width. Therefore, compared to the case where the deformed portion 7b is sandwiched outside the center of the deformed portion 7b in the width direction and the width of the deformed portion 7b is equal to or less than the width of the groove portion 32a, the radius of rotation of the deformed portion 7b becomes larger. In addition, the portion sandwiched between the projecting portions 24 is closer to the end portion of the deformation portion 7b in the deformation direction (inward direction). For these reasons, the deformable portion 7b can be deformed with a smaller force than when the deformable portion 7b is sandwiched outside the center of the deformable portion 7b in the width direction, and the container main body and the lid can be more stably connected. between can be sealed.

In the present embodiment, the accommodated portion 7a of the packing 7 is hollow, but since the reinforcing portion 7f is provided inside the accommodated portion 7a, it is less likely to be crushed inside the groove portion 32a. Further, the accommodated portion 7a may be solid. If the accommodated portion 7a is made solid, the accommodated portion 7a can be easily accommodated in the groove portion 32a because the rigidity is greater than when it is hollow.

In the present embodiment, a tapered portion 7g is formed at the end of the accommodated portion 7a opposite to the deformed portion 7b, so that the accommodated portion 7a can be more easily accommodated in the groove portion 32a.

(Modification)
In this embodiment, the lid 3 is the first body provided with the groove 32a, and the container body 2 is the second body provided with the protrusion 24. Alternatively, the lid body 3 may be provided with a protrusion to serve as the second body. However, when the container body 2 is provided with the protrusions 24, the structure of the container body 2 can be simpler than when grooves are provided, and the container body 2 can be easily cleaned.

Moreover, in the present embodiment, the engaging member is provided on the container main body 2 , but it may be provided on the lid 3 .

Furthermore, in this embodiment, the engagement mechanism is composed of the hinge portion and the engagement member. , two engaging members may constitute the engaging mechanism.

It should be understood that the embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope of equivalence to the scope of claims.
