JP 2013-154922

The container with a lid of Patent Document 1 is convenient in that the jig for taking out the contents is held inside, but the structure is complicated because the lid is divided into a fixed lid and a movable lid. The manufacturing cost is high.
On the other hand, the lower half of the lid peripheral wall of the lid is simply fitted to the upper part of the cylinder peripheral wall of the container body, and a pair of separation lines are formed from the lower end to the upper end side of the lid peripheral wall to form both separation lines. The peripheral wall portion of the lid between the two is a movable wall portion that can rotate outward with the upper end as a rotation axis, and a butter knife or the like is inserted from an insertion opening that opens by rotating this movable wall portion sideways. , It is also possible to hold it in this inserted state. However, in such a configuration, the movable wall portion must be operated by removing the lid from the container body, which is not convenient.

An object of the present invention is to propose a container lid and a container with a lid, which have a relatively simple structure but are easy to use.

First, the basic configuration of the present invention will be described.
The basic configuration is
A container body 2 having a tubular peripheral wall 6 rising from the outer periphery of the bottom wall 4 and having a flange 8 attached to the upper end of the tubular peripheral wall 6.

It is a partially enlarged view of the cross-sectional view of FIG. It is a front view of the container of FIG. It is explanatory drawing of the use method of the container of FIG.

1 to 5 show a container with a lid according to the first embodiment of the present invention. The container with a lid is formed of a container body 2 and a lid body 10. Each of these members can be made of a synthetic resin material.

The container body 2 has a tubular peripheral wall 6 that opens the upper end from the outer periphery of the bottom wall 4. A collar portion 8 is attached to the upper end of the cylinder peripheral wall 6. The peripheral end portion 9 of the collar portion 8 in the illustrated example is inclined downward and outward. As shown in FIG. 3, a ventilation groove g that crosses the collar portion 8 in the circumferential direction is formed at an appropriate position in the circumferential direction of the collar portion 8.
The tubular peripheral wall 6 of the present embodiment has a substantially square tubular shape, but this structure can be appropriately changed.

The lid body 10 has a lid peripheral wall 12 fitted to the peripheral end portion 9 of the flange portion 8 and a top plate 16 stretched over the upper surface of the lid peripheral wall 12.
The lid body 10 is preferably formed by sheet molding, but it can also be formed by another method, for example, thin-wall molding by injection molding.

In the present embodiment, the lid peripheral wall 12 is formed by projecting a lower half portion 12b that expands downward and outward in a skirt shape from the lower end of the straight tubular upper half portion 12a. Further, as shown in FIG. 2, an engaging convex portion 14 protruding inward is formed in a part of the peripheral wall 12 in the circumferential direction, and the lid body 10 is formed from the position shown by the dotted line in FIG. 3 during the closing operation. The engaging convex portion 14 gets over the peripheral end portion 9 of the flange portion 8 as it is moved to the position shown by the solid line in the figure.

The top plate 16 has a flat outer peripheral portion 18 adjacent to the upper end of the lid peripheral wall 12. The outer peripheral portion 18 is placed on the upper surface of the flange portion 8.
In the present embodiment, the portion of the top plate 16 inward from the outer peripheral portion 18 is a bulging portion 20 that bulges upward. However, this structure is not essential, and for example, the entire top plate 16 may be formed into a flat plate.
As shown in FIG. 2, the top plate 16 shown in the figure has its peripheral portion formed on an arcuate bent plate portion 20a when viewed from the side, and the remaining portion formed on a horizontal plate portion 20b.
From the boundary line b of the outer peripheral portion 18 and the bulging portion 20 when viewed from above, the appropriate position of the bent plate portion 20a (the portion corresponding to both ends and the intermediate portion of the long side of the rectangular lid in a plan view in the illustrated example). A plurality of auxiliary recesses 21 are formed. The auxiliary recess 21 enables the lids to be locked to each other when a plurality of lids are stacked.
Further, a recessed portion 22 that bites into the bulging portion 20 when viewed from above is formed at one location in the circumferential direction of the bending plate portion 20a. The bottom portion of the recessed portion 22 is a flat plate portion 22a that is flush with the outer peripheral portion 18.
A substantially U-shaped separation line 24 is bored in the flat plate portion 22a. The separation line 24 of the illustrated example is formed by a pair of side line portions 24a extending inward from the outer end side of the flat plate portion 22a and a V-shaped front line portion 24b connecting the tip e2 of these side line portions 24a. .. The plate portion partitioned on three sides by the separation line 24 is the operating section 28. The pair of lateral line portions 24a in the illustrated example are parallel lines, but these structures are appropriately formed, for example, by forming the entire shape of the separation line 24 into a substantially V shape so as to intersect the tip e2 of the lateral line portion 24a. Can be changed.
The operational section 28 has a base 28a and a tip 28b. The base portion 28a is located closer to the base end e1 of the lateral line portion 24a and is continuous with the surrounding top plate portion when the operating section 28 is pushed down, and the tip portion 28b is closer to the front line portion 24b. It is located and is the part that descends most by pushing down the operational section 28.
By pushing the operation section 28 from the outside of the top plate 16, the separation line 24 separates the operation section 28 from the surrounding flat plate portion on the three sides, descends from the tip 28b side, and inserts the insertion port. It suffices if A is configured to open. In the present embodiment, it is formed as a break line which is a perforation, but it may be formed as a thin-walled weakening line or a slit, for example.
In the illustrated example, the auxiliary refraction line 26, which is a thin line, linearly connects the base ends e1 of the pair of lateral line portions 24a forming the substantially U-shaped separation line 24. The auxiliary bending line 26 may be any shape as long as it can be easily bent on the base side of the operation section 28. For example, the auxiliary bending line 26 approaches each other from the base end e1 of the pair of lateral line portions 24a. A structure in which a pair of notches protruding in the direction (opposing direction) may be formed may be used. Further, the auxiliary bending line 26 does not have to be provided.
Although not shown, when the separation line 24 is provided at a position in contact with the outer edge of the top plate 16, the shape of the separation line 24 viewed from above is cut in half along the center line. (For example, it can be approximately L-shaped). In this case, the first auxiliary separation line that vertically traverses the peripheral wall of the lid is extended from one end of both ends of the L-shape that is in contact with the outer edge of the top plate, and the auxiliary refraction line is extended from the other end in a direction orthogonal to the center line. It is preferable to provide and hang a second auxiliary separation line that traverses the peripheral wall of the lid from the tip of the auxiliary refraction line. Further, the shape of the separation line 24 is not limited to these as long as the content extraction jig T can be inserted and held.
In the above configuration, as shown in FIG. 5, when the operating section 28 is pushed in with, for example, a jig T for taking out the contents such as a user's finger or a butter knife, the operating section 28 moves downward with the auxiliary refraction line 26 as the center. The insertion port A opens by rotating to. A butter knife T can be inserted and held in the insertion port A.
When taking out the contents, pull out the butter knife T from the insertion port A, remove the lid 10 from the container body 2, and use the butter knife T to cut out both required contents from the container body 2 and take them out. Just do it.
In the present embodiment, since the operating section 28 has elasticity, when the butter knife T is pulled out, the operating section 28 is restored and deformed so as to close the insertion port A.

Hereinafter, a container with a lid according to another embodiment of the present invention will be described. In these explanations, the description of the same configuration as that of the first embodiment will be omitted.

6 to 10 show a container with a lid according to a second embodiment of the present invention. In the present embodiment, the configurations of the separation line and the operation section of the first embodiment are changed.
That is, the separation line 24 is formed in the bent plate portion 20a by omitting the recessed portion 22 and the auxiliary refraction line 26 in the configuration of the first embodiment. In the separation line 24 of the illustrated example, a pair of side line portions 24a to be cut into the bending plate portion 20a are formed from the vicinity of the boundary line b with the outer peripheral portion 18 to the vicinity of the upper end portion of the bending plate portion 20a, and the pair of these side line portions 24a are formed. The tip e2 of the lateral line portion 24a is connected by a linear front line portion 24b, but this configuration can be changed as appropriate. For example, a substantially U-shaped separation line may be formed so as to straddle the stiffening rib described later.
The operating section 28 is formed as an elastic plate portion at a bending plate portion partitioned on three sides by the separation line 24. Since the lid body of the present invention is provided with the separation line 24 on the top plate portion, it can be efficiently manufactured by using sheet molding. That is, in the case of sheet molding, it is difficult to mold in a form having an operation section partitioned by a separation line on the side surface of the molded product due to the structure of the mold, and the separation line is used as post-processing after sheet molding. It had to be drilled. On the other hand, in the present invention, since the separation line is provided on the top plate portion as described above, it can be easily formed by sheet forming.
In a preferred illustrated example, the outer peripheral portion 18 of the top plate 16 is placed on the outer half portion 8b of the flange portion 8, and the tip portion of the operation section 28 is left as the movable plate portion 30, and the rest of the operation section is left. A stiffening protrusion 32 is projected from the back surface of the portion, and the lower surface of the stiffening protrusion 32 is placed on the inner half portion 8a of the flange portion 8.
The stiffening protrusion 32 in the illustrated example is a stiffening rib having a constant width in the inward and outward directions as shown by a dotted line in FIG. The shape of the stiffening rib seen from the side is substantially fan-shaped (see FIG. 7), and the portion of the lower end surface closer to the outer peripheral portion 18 is placed on the inner half portion 8a of the flange portion 8. This structure can be changed as appropriate.
In this configuration, the operating section 28 is connected to the peripheral wall 12 by forming the stiffening protrusion 32. As a result, the elastic deformation force of the operation section 28 can be further strengthened by applying the restoring deformation force of the lid peripheral wall 12 to the operation section 28.
Further, instead of this configuration, by forming the stiffening protrusion 32, the deformable portion of the operation section 28 can be limited to the movable plate portion 30.
As shown in FIG. 10, when the movable plate portion 30 is pushed in from the outside with a user's finger, a butter knife T, or the like, the movable plate portion 30 is bent and deformed inward, and the insertion port A opens. T can be inserted and held. When the butter knife T is pulled out from the insertion port A, the movable plate portion 30 is elastically restored to its original position, and the insertion port A is closed. After that, the lid 10 can be removed from the container 2 to cut out the contents.
Since the stiffening protrusion 32 is provided, when the movable plate portion 30 is elastically deformed downward, the section portion other than the movable plate portion and the stiffening protrusion 32 are also slightly elastically deformed, and these are bent. It exerts a large elastic force as a combination of a leaf spring and a vertical leaf spring. As a result, the elastic restoring force of the entire operating section 28 is increased, so that the insertion port A can be reliably closed.
