DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be briefly described based on the drawings, showing the effects of the present invention.

The upper opening of the container 1 is covered with the lid 4, and the lid 4 is pushed down to removably engage and lock the locking protrusion 5 of the lid 4 into the engagement hole 3 of the outer circumference 2 of the container 1. Then, the lid 4 covers the upper opening of the container 1 and is held in a closed state.

At this time, since the engagement hole 3 is provided at the corner of the outer circumference 2 of the container 1, and the locking convex portion 5 is also provided at the corner of the lid 4, as in Patent Document 1, Compared to a configuration in which the engagement recess of the container and the engagement protrusion of the lid engage and engage over a wide range, the range in which the engagement protrusion 5 engages and engages the engagement hole 3 is small (corner Therefore, for example, by simply pushing down the lid 4 with a light force, the locking protrusion 5 easily engages and locks in the engagement hole 3, making it easy to attach the lid 4 to the container 1. It will be done.

Also, when removing the closed lid 4 from the container 1, the engagement hole 3 and the locking protrusion 5 have a small engagement range, so the locking protrusion 5 can be easily engaged and disengaged from the engagement hole 3. This operation of removing the lid 4 is easily performed.

Further, the engagement hole 3 provided at a corner of the outer circumferential portion 2 of the container 1 so as to intersect with the corner edge of the corner is the above-mentioned Patent Document 1 in which an engagement recess is formed around the entire circumference of the container. Compared to the above structure, the design can be easily realized because the formation range is smaller, and the locking projections 5 provided at the corners of the lid body 4 are also formed in a large area in the circumferential direction of the lid body. Since the formation range is smaller than that of Patent Document 1, the design can be realized easily.

In addition, it is possible to improve the marketability of the container 1 by adding designs and decorations to the outer periphery 2 of the container 1; The engagement hole 3 can be designed and realized so that it does not easily spoil the design or decoration and exhibits a good appearance.

Specific embodiments of the present invention will be described based on the drawings.

The container with a lid of this embodiment includes a container 1 with an open top, and a lid 4 that removably covers and closes the top opening of the container 1.

The container 1 of this embodiment includes an outer circumferential portion 2 formed by bending a band plate portion 6 into an upright rectangular frame shape in a plan view, and a container portion 7 integrally molded from a thin synthetic resin. The container part 7 is housed inside the outer peripheral part 2 so as to be dropped therein, and the container part 7 is assembled to the outer peripheral part 2 in a locked state by locking the edges. (See Figure 1).

Further, the outer circumferential portion 2 of this embodiment has a structure in which the band plate portion 6 constituting the outer circumferential portion 2 is overlaid with an inner plate portion 9 on the outer plate portion 8, and the inner plate portion 9 is overlapped with the outer plate portion 8. The upper edge portion is provided at a lower position than the upper edge portion of the outer plate portion 8.

Specifically, the band plate part 6 is made of a hard horizontally elongated cardboard 19 with a thickness of about 1 mm, and both ends of the band plate part 6 in the length direction are overlapped and connected by a connecting means to form a frame. (see FIG. 1), and as shown in FIG. A shaped frame bending groove 15 is provided (incisions are formed using a groove forming blade), and each part is bent at a right angle using the four frame bending grooves 15 as folding edges. The rectangular frame-shaped outer circumferential portion 2 has these four right-angled bent portions serving as corner portions, and the outer circumferential portion 2 can also be folded into a strip shape through the four frame bending grooves 15. (not shown), and the outer peripheral portion 2 is configured to be packed and shipped in this folded state. In addition, the outer peripheral part 2 (band plate part 6) may be made of foamed synthetic resin.

Further, the two frame bending grooves 15A existing on one diagonal line of the strip plate portion 6 when forming the outer peripheral portion 2 are cut out into relatively wide vertical grooves, and the frame bending grooves 15A are cut out into relatively wide vertical grooves. The two sides of the band plate portion 6 adjacent to the frame bending groove 15A are configured to be bendable in a direction of 90 degrees or more in plan view via the frame bending groove 15A.

Further, the two frame bending grooves 15B existing on the other diagonal of the strip plate portion 6 when forming the outer circumferential portion 2 are cut into longitudinal grooves narrower than the frame bending grooves 15A. and the two sides of the band plate portion 6 adjacent to the frame bending groove 15B are configured to be able to be bent to a position forming an angle of about 90 degrees in plan view via the frame bending groove 15B. has been done. That is, from this 90 degree state, the two sides of the band plate portion 6 adjacent to the frame bending groove 15B are bent through the frame bending groove 15B in a direction in which the two sides are enlarged to more than 90 degrees in plan view. However, it is possible to bend the strip part 6 at an angle of 90 degrees or less in a plan view because one of the edges of the strip part 6 adjacent to the frame bending groove 15B contacts the other or both edges contact each other. It is designed to be difficult.

In other words, the frame bending groove 15B changes from the unfolded state of the outer peripheral portion 2 in which the angle formed by the two sides of the paper material 5 adjacent to the frame bending groove 15B is 90 degrees. The bending range is restricted to only about a 90 degree range up to the folded state of the outer peripheral portion 2 where the angle formed by the two sides of the paper material 5 adjacent to the groove 15B is 180 degrees. Therefore, when folding the outer peripheral part 2 in the unfolded state, the structure is such that it can be folded only in the direction in which the angle formed by the two sides of the band plate part 6 adjacent to the frame bending groove 15B expands to 90 degrees or more. On the contrary, when unfolding the outer peripheral part 2 in the folded state, when the angle formed by the two sides of the band plate part 6 adjacent to this frame bending groove 15B becomes about 90 degrees in plan view, the angle is reduced further. It is configured so that it cannot be folded in any direction (so that the outer circumferential portion 2 does not go beyond the expanded rectangular frame shape and return to the folded state).

Furthermore, to explain the means for connecting both ends of the band plate part 6, a configuration is adopted in which a glue allowance 18 is provided at both ends of the band plate part 6, and both ends are glued via this glue allowance 18. However, a configuration may be adopted in which both ends of the band plate portion 6 are adhered with adhesive tape such as paper tape or vinyl tape, or other connection means may be adopted.

In addition, as shown in FIG. 5, the band plate part 6 constituting the outer circumferential part 2 has four corners that overlap with the frame bending grooves 15, at slightly upper positions in the vertical direction of the corner edges of the corner parts. The engagement hole 3 in the shape of a horizontal slit (horizontal rectangular hole) is formed through the engagement hole 3 so as to intersect with this corner edge.

This engagement hole 3 is formed in the cardboard 19 constituting the band plate part 6 in advance, for example, before the band plate part 6 is bent through the frame bending groove 15 (to form a rectangular frame-shaped body). It is good to form it.

Although not shown in detail, the cardboard 19 constituting the outer circumferential portion 2 (strip plate portion 6) of this embodiment has one side surface (inner side in FIG. 3) of the unfolded state before folding shown in FIG. An exterior sheet (not shown) having functions such as waterproofness, durability, and decoration is pasted on the outer surface (the surface existing in The exterior sheet is configured to be exposed on the outer surface of the plate portion 8, the inner surface of the inner plate portion 9, and the continuous portion (upper and lower portion) of the outer plate portion 8 and the inner plate portion 9. .

Further, the container portion 7 of this embodiment is made of a thin material made of synthetic resin such as polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), etc., and has an upper opening as shown in FIG. It is formed (integrally molded) into a container (box) having a rectangular shape in a plan view that is approximately the same as the outer shape of the outer peripheral part 2 and of a size that can be accommodated within the outer peripheral part 2. Note that the shape of the container portion 7 is not limited to this embodiment, and various shapes such as a hexagon, an octagon, a drum shape, a gourd shape, a round shape, and modified shapes thereof in plan view can be adopted. It is also possible to easily prepare the outer circumferential portion 2 having a shape corresponding to the container portion 7 having various shapes.

Furthermore, as shown in FIGS. 1 and 2, the entire outer periphery of the container portion 7 is provided with a flange-like protrusion outward, and the entire periphery of the flange has an inverted groove shape with the upper part serving as the groove bottom. This inverted groove-shaped full-circumference collar is latched from above to the container-locking upper edge 11 provided on the inner surface of the outer peripheral portion 2 (strip plate portion 6). The locking portion 12 is configured as a lockable locking portion 12 (peripheral locking recess 12), and a wide area of the locking portion 12 excluding the four corners is locked to the upper edge portion 11 for container locking, so that the container locking recess 12 can be locked. The container portion 7 is attached to the inside of the band plate portion 6.

Moreover, this container part 7 is formed in a shape that allows a plurality of containers to be stacked and nested.

The lid 4 of this embodiment is formed into a rectangular shape in a plan view, which is equivalent to the outer shape of the container 1, and the lid 4 covers and closes the upper opening of the container 1 at the four corners. A locking convex portion 5 is provided so as to protrude inwardly and releasably locks into the engagement hole 3 when the lock is engaged.

Specifically, the lid body 4 is made of a transparent synthetic resin board material such as polystyrene (PS), polyethylene terephthalate (PET), or polycarbonate (PC), and as shown in FIG. A fitted edge 16 having an inverted L-shaped side cross section is provided (integrally molded) to be fitted (externally fitted) on the upper edge of the portion 2, and this fitted edge 16 includes: The locking convex portions 5 are provided (integrally molded) on the inner surfaces of the hanging outer edges of the four corners and have a shape that projects inward in the form of a horizontal band.

Further, as shown in FIG. 2, the locking convex portion 5 is formed to have a side cross-sectional shape convexly curved inward, so that it can be easily locked into and disconnected from the engagement hole 3. By locking and fitting the locking protrusion 5 into the engagement hole 3, the lid 4 covers and closes the upper opening of the container 1 (the lid 4 is not fitted into the container 1). It is configured to be held in a locked state).

Further, this lid body 4 has a knob piece 17 protruding from one of the four corners (integrally molded), and the lid body 4 can be easily opened and closed using this knob piece 17. is configured to take place.

Although not shown, it is also possible to add a function to prevent the lid 4 from opening by wrapping around the container with a lid of this embodiment a band displaying (printing) the product name, expiration date, contents ingredients, etc. (The applicant has found that even without such a strap, the locking force of the engaging hole 3 at the four corners and the locking protrusion 5 of the locking protrusion 5 is sufficient to prevent the lid 4 from opening. (This has been confirmed through prototype experiments.)

Moreover, this lid body 4 is formed in a shape that allows a plurality of lids to be stacked and nested. That is, the container with a lid of this embodiment is shipped with the outer peripheral part 2, the container part 7, and the lid 4 separated, but at this time, a plurality of outer peripheral parts 2 folded into strips and a plurality of stacked outer peripheral parts 2 are shipped. It is possible to transport and store the container portion 7 and the plurality of stacked lid bodies 4 without bulking up.

By the way, the applicant has obtained Patent No. 7031864.

Briefly explaining this patent No. 7031864, there is an outer circumferential portion provided with an upper edge portion for locking the container along the circumferential direction of the inner surface like the container 1 of this embodiment, and an upper edge portion for locking the container. A container is assembled into the outer peripheral part by locking a peripheral edge locking recess of the outer peripheral part to the edge, and the outer peripheral part is a decorative body with a pattern or the like applied to the outer surface. A foamed resin board, such as a polystyrene sheet, formed in a strip shape is bent along a bending part formed in advance on the board surface to form a frame-like board with a rectangular shape in plan view surrounding the container part. A groove (horizontal groove) that is recessed outward is cut into the inner surface of this outer circumference, and at the same time, a groove (horizontal groove) that extends downward from the deep part of the lower groove surface of the groove (rear groove) is formed. A notch is formed along the downward extension of the surface, and the inner part is deformed to protrude inwardly from the notch (vertical groove part) formed in the groove, and this inwardly protruding part is formed in the container. It is configured as an upper edge for locking.

In this embodiment, the upper edge portion 11 for retaining the container is provided inside the outer circumferential portion 2 using a simpler structure different from that of this patent No. 7031864.

Specifically, as shown in FIG. 3, the cardboard 19 constituting the horizontally long strip portion 6 has concave grooves having a length in the horizontal and lateral direction at positions near the upper edge and near the bottom of the inner surface. A shaped overlapping notch groove 13 is provided (the cut is formed using a groove forming blade), and as shown in FIG. It is bent inward (when it becomes the outer periphery 2 of the shape).

That is, the horizontally long band plate part 6 has an upper part and a lower part folded over each other, and this folded state is held by a fastening means such as adhesive, so that the inner plate part 9 is superimposed on the outer plate part 8 (the outer part is folded). The upper and lower parts of the plate part 8 are folded inward, and the upper edge of the lower inner plate part 9A of the upper and lower inner plate parts 9 is the upper edge of the outer plate part 8. (See FIGS. 4(b) and 5).

Further, a locking gap 10 is provided between the upper edge of the lower inner plate portion 9A and the outer plate portion 8. Specifically, in the lower inner plate part 9A, a notch groove 14 for tilting in the form of a concave groove having a length in the horizontal direction is provided in advance in the middle of the side surface that overlaps with the outer plate part 8 (groove formation). A notch is formed in advance in the cardboard 19 using a blade (see FIGS. 2 and 4(b)), and the side below the tilting notch 14 is held overlapped with the outer plate part 8 by the fastening means. , the upper side of this tilting notch 14 is not bonded to the outer panel 8, but is provided so that it can freely tilt inward with respect to the outer panel 8 using the tilting notch 14 as a folding edge, and can be tilted to the outside. The gap between the upper edge of the lower inner plate part 9A, which projects inward from the inner surface of the plate part 8, and the outer plate part 8 constitutes the locking gap 10. Note that this tilting notch groove 14 is formed on the inner surface of the lower inner plate portion 9A when the strip plate portion 6 is formed on the outer peripheral portion 2 (in this embodiment, the tilting notch groove 14 is formed). Alternatively, the lower inner plate portion 9A below the tilting notch 14 may not be fixed to the outer plate portion 8 ( A configuration in which the outer plate portion 8 and the outer plate portion 8 are not overlapped and held may be adopted.

The upper edge portion of this lower inner plate portion 9A is configured as the container locking upper edge portion 11, and this container locking upper edge portion 11 covers substantially the entire inner circumference of the band plate portion 6. A locking portion 12 provided on the peripheral edge of the container portion 7, which will be described later, is locked to this upper edge portion 11 for locking the container, and a locking portion 12 is connected to the locking gap 10. By disposing the hanging outer edge portion, the container portion 7 is configured to be assembled inside the strip portion 6 (the outer peripheral portion 2).

Further, a portion of the lower inner plate portion 9A above the tilting notch groove 14 of each of the frame bending grooves 15 (15A, 15B) is formed as a notch 20 penetrating the cardboard 19 in the front and back directions. At the same time, the notch portion 20 is formed with an inclined edge 21 on the left and right edges such that the facing distance increases toward the upper side. By forming the notch 20 and the inclined edge 21, the container locking upper edge 11 does not exist at the corner of the outer peripheral portion 2 (the container locking upper edge 11 is not provided on the entire inner circumference of the strip plate portion 6, but is provided on almost the entire circumference excluding the four frame bending grooves 15), so that the upper edge portion 11 for retaining the container has the following: The container portion 7 is assembled inside the outer circumferential portion 2 by being locked at a portion other than the corner portions of the locking portion 12 of the container portion 7 .

That is, in the container part 7 with the locking part 12 integrally molded from synthetic resin, the locking part 12 at the corner is not a right-angled shape in plan view but has an R shape in consideration of ease of removal during demolding. However, if you try to lock the R-shaped locking part 12 at this corner to the container locking upper edge 11 that is bent at right angles in plan view, the container locking part at this corner will The upper edge 11 for locking easily comes into contact with and interferes with the locking part 12, which could cause insertion resistance and hinder assembly work. In this embodiment in which the portion 11 is not provided, such trouble does not occur and the work of assembling the container portion 7 to the outer peripheral portion 2 is easily performed.

Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
