[0004]

As described above, in the conventional packaging container, since the lid body is merely formed in the substantially hollow truncated pyramid shape, the pressing force is not properly transmitted from the upper side to the lower side of the lid body. However, there is a problem in that the lid cannot be smoothly and easily fitted to the tray. To solve this problem, a method of pressing the lid on the tray a little more strongly may be considered, but if this is done, the lid made of a thin synthetic resin sheet may be crushed and deformed, and it may not return to its original form. There are many. Such adverse effects, for example, when storing high-class Japanese confectionery, the aesthetic balance, the high-class feeling, and the cleanliness of the high-class Japanese confectionery and the packaging container are destroyed, and as a result,
It cannot be left unattended, as the promotional function will be significantly reduced.

The present invention has been made in view of the above, and it is possible to easily cover the tray with the lid, and the lid can be easily deformed even when the lid made of the synthetic resin sheet is strongly covered. It is intended to provide no packaging containers.

[0006]

In order to achieve the above object, in the invention according to claim 1, a tray formed of a flexible resin sheet and a tray formed of a flexible resin sheet are formed into a tray. A transparent lid which is detachably covered, wherein the tray is formed in a substantially rectangular shape in a plan view and has a substantially groove-shaped cross section, and a partition body for dividing a plurality of internal spaces in a longitudinal direction is provided on an inner bottom thereof. Formed, extend the folded outer wall from the upper end of the peripheral wall of the tray and fold outward, and bend the folded outer wall outward to form a step shoulder support for supporting the lid body, in the circumferential direction of the folded outer wall, A plurality of retaining stoppers are formed at predetermined intervals, the lid is formed in a hollow rectangular pyramid trapezoidal plane approximately rectangular shape, and a bent wall that is recessed inward is formed at least in the vertical direction of the short inclined peripheral wall of the lid. form And, in the lower circumferential direction of the inclined peripheral wall of the lid member, it is characterized in that the full retaining holes fitted respectively to the plurality of retaining stopper formed at a predetermined interval. It is preferable that a pattern is formed on the bottom surface of the tray and the bottom surface and the pattern are made uneven.

Here, in the partition body in the claims, the inner space of the tray is mainly divided into two or three, but the partition space is not limited to this, and may be, for example, 4, 5, and 6. It may be divided into individual pieces. The bent wall may be formed at least in the vertical direction of the short inclined peripheral wall of the lid body, or may be formed in the vertical direction of all the inclined peripheral walls of the lid body including the long inclined peripheral wall. In addition, the pattern can be freely formed as long as it does not impair the aesthetic balance, the sense of quality, and the cleanliness suitable for small articles, and is not particularly limited. Further, the packaging container is mainly used for packaging a plurality of foods, specifically, Japanese confectionery and Western confectionery, but is not limited to this, and is a small item such as miscellaneous goods, stationery, toys, and medicines. It can also be used for packaging such as.

According to the present invention, when packaging small articles, a plurality of small articles may be mounted on the bottom surface of the tray and the opening of the tray may be covered with the lid from above. At this time, the bent wall bent inward of the lid exerts a spring function to appropriately apply pressure to the lid from the upper side to the lower side. Further, since the bent curved wall exerts a restoring function, even if the lid made of a thin synthetic resin sheet is slightly strongly covered, the partially deformed lid restores its original form.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 6, the packaging container according to the present embodiment stabilizes two Japanese sweets (not shown). Tray 1 that stores side by side in the
A lid 20 is detachably and tightly fitted on the tray 1.

The tray 1 is formed of a non-polluting thin synthetic resin sheet that does not generate harmful substances such as dioxins, specifically, a PPF sheet, a PET sheet, a PVC sheet, and a PP sheet are vacuum (compressed) molded. By doing
It is shaped like a bottomed cylinder that is lower than the lid 20, and is colored (for example, white or black) so that the Japanese confectionery stands out. As shown in FIG. 1, the tray 1 having excellent flexibility and elasticity is
The four corners are rounded and chamfered into a substantially rectangular plane, and are formed in a groove with a substantially grooved cross section. The flat center of the inner bottom has a substantially U-shaped cross section that divides the internal storage space 2 into two in the longitudinal direction. The partition body 3 is integrally formed to project.

The bottom of the tray 1 divided into two parts is shown in FIG.
As shown in Fig. 4, a pattern 4 consisting of a plurality of continuous waves that creates an aesthetic balance, a sense of luxury, a sense of cleanliness, etc. is integrally formed with the Japanese sweets to be mounted, and unevenness is provided between each bottom surface and the pattern 4. Are formed. Further, as shown in FIGS. 1 and 2, a folded outer wall 6 that extends outward and folds back to the upper end of the peripheral wall 5 that forms the front, rear, left, and right of the tray 1 is a flat and short connection that extends horizontally outward. It is continuously provided through the wall 7, and the folded outer wall 6 has a substantially central portion in the vertical direction.
Step shoulder support 8 that supports the lower end of the inclined peripheral wall 5 of the lid 20
Is formed by being bent outward, and a bulging wall 9 bulging outward is formed below the folding outer wall 6 in the up-down direction, and the bulging wall 9 is formed in the circumferential direction including the four corners of the folding outer wall 6. The rib-shaped retaining stoppers 10 are integrally arranged at a predetermined interval.

The upper ends of the peripheral wall 5, the folded outer wall 6 and the connecting wall 7 are formed so that the center in the left-right direction is high and both sides are low. In addition, each stopper 10 is attached to the tray 1.
The first inclined side 11 that is integrally formed on the upper part of the folded outer wall 6 and gradually expands as it goes from the opening direction (upward direction) to the bottom direction (downward direction) of the tray 1, and the first inclined side The tray 1 and the first bent side 12 that is bent inward of the folded outer wall 6 are connected to the lower end of the side 11. The surface of each retaining stopper 10 is selectively coated with a paint for wear prevention (not shown).

The lid 20 is a thin synthetic resin sheet which is particularly easy to recycle and is transparent and does not generate harmful substances such as dioxins. Specifically, it is made of A-PET, PPF sheet, PET sheet, PVC sheet. It is vacuum (compressed) molded with a sheet and a PP sheet. As shown in FIGS. 1 and 3 to 6, the lid body 20 which is excellent in flexibility and elasticity is formed into a hollow, substantially truncated pyramid trapezoidal shape having four corners vertically long, and has an open bottom surface. It is wide and has a narrow ceiling, and is transparent so that you can grasp the condition of Japanese sweets. The lid 20 has a thick ceiling,
The entire inclined peripheral wall is thinly formed, and the inner surface is subjected to a boarding process so as not to be fogged. In the lower circumferential direction of the entire inclined peripheral wall, the retaining holes 22 fitted and locked to the retaining stoppers 10 have predetermined intervals. And are arranged integrally.

A part of a pair of wide and long inclined peripheral walls of the lid 20 is formed so as to bulge outward, and a space between the part and the remaining part is formed in a semi-circular shape in a side view (FIGS. 1 and 3). , See FIG. 4).
Further, as shown in FIG. 3, a pair of narrow and short slanting peripheral walls of the lid body 20 is formed with a curved wall 21 that is slightly recessed while drawing a gentle curve inward, and is integrally curved in the vertical direction. 21 exhibits a spring function and a restoring function when the lid 20 is fitted.

As shown in FIGS. 5 and 6, each retaining hole 22 is formed by inclining a part of the lower portion of the inclined peripheral wall of the lid body 20 at another angle, and is formed on the first inclined side 11 from the outside. The second inclined side 23 facing and overlapping with each other and the lower end of the second inclined side 23 that gradually inclines while gradually expanding are bent inward of the lid body 20, and are bent to the first bent side 12 from the outside. The second bent side 24 is opposed to and overlaps. A paint for wear prevention (not shown) is selectively applied to each retaining hole 22.

In the above structure, when packaging Japanese sweets, a plurality of Japanese sweets may be mounted and supported side by side on the bottom surface of the tray 1, and the lid 20 may be pushed into the opening of the tray 1 from above to be tightly fitted. At this time, the lid body 20 is smoothly slid and guided without hitting the first inclined side 11 of the retaining stopper 10 so that the lid body 20 gradually descends and spreads to the outer side in the horizontal direction of the tray 1, and thereafter, The second bent side 24 is fitted and locked to the first bent side 12, and the second tilted side 23 overlaps the first tilted side 11. As a result, the lower end portion of the lid body 20 is supported by the step shoulder support 8 of the tray 1, and a plurality of Japanese sweets are packaged.

According to the above construction, since the bent wall 21 that bends very loosely inward when the lid 20 is tightly fitted exerts a spring function, the pressing force is appropriately transmitted to the lid 20 vertically from above and the tray The lid 20 can be smoothly and easily tightly fitted in the first cover 20. Therefore, since a strong fitting force is not required, the thickness of the tray 1 and the lid 20 can be reduced, and reduction in manufacturing cost and weight reduction can be expected. Also,
Since the flexible bending wall 21 exerts a restoring function, even if the lid body 20 made of a thin synthetic resin sheet is fitted to the lid a little, it is possible to easily restore the partially collapsed lid body 20 to the original form. You can Therefore, even when high-quality Japanese sweets are stored, the aesthetic balance, the high-class feeling, the cleanliness, etc. produced by the high-class Japanese sweets and the packaging container are not deteriorated, and the sales promotion function is not deteriorated.

Further, since the retaining stopper 10 of the tray 1 is not merely a semi-elliptical cross section, but the first inclined side 11 having a guiding function is partially inclined, the retaining stopper 10 has a retaining hole. The 22 does not collide strongly and is not caught or caught. Therefore, it is possible to secure the tray 1 without removing it without using a strong fitting force.
The lid 20 can be smoothly and tightly fitted to the
In addition, the tray 1 and the lid 20 are not deformed and the appearance is not deteriorated or damaged. Further, if the pattern 4 is formed on the bottom surface of the tray 1 and the bottom surface and the pattern 4 are in a concavo-convex relationship, the sweets will not be laterally displaced and collapsed due to frictional force.

Next, FIGS. 7 to 12 show a second embodiment of the present invention. In this case, the inner storage space 2 is divided into three compartments in the inner bottom of the tray 1 in the longitudinal direction. The partition bodies 3 each having a substantially inverted U-shaped cross section are integrally arranged side by side, and on the bottom surface divided into these three, from a plurality of continuous waves that create an aesthetic balance, a sense of luxury, a sense of cleanliness, etc. with Japanese sweets. The patterns 4 are formed integrally with each other. The other parts are basically the same as those in the above-described embodiment, and therefore the description thereof is omitted. In this embodiment, the same effects as those of the above embodiment can be expected, and it is obvious that more Japanese sweets can be packaged.

The folded outer wall 6 of the above embodiment is
It may be folded back vertically from the upper end of the peripheral wall 5 downward in the outward direction, or may be folded back while being inclined downward in the outward direction. Also, lower the center of the peripheral wall 5 and the folded outer wall 6,
It is also possible to make the left and right sides high. Further, the second inclined side 23 may be formed by inclining a part of the lower portion of the inclined peripheral wall of the lid body 20 at the same angle.

[0021]

As described above, according to the present invention, the tray is formed in a substantially rectangular shape in a plan view and has a substantially groove-shaped cross section, and a partition body is formed on the inner bottom thereof to divide the internal space into a plurality of parts in the longitudinal direction. ,
Extend the folded outer wall from the upper end of the peripheral wall of the tray and fold it outward, and bend the folded outer wall outward to form a step shoulder support that supports the lid body. The lid is formed at a predetermined interval, and the lid is formed in a hollow rectangular pyramid trapezoidal plane and is substantially rectangular, and a bent wall that is recessed inward is formed at least in the vertical direction of the short inclined peripheral wall of the lid, and the inclination of the lid is formed. Since the retaining holes that fit in the plurality of retaining stoppers are formed at predetermined intervals in the lower circumferential direction of the peripheral wall, the tray can be covered with the lid relatively easily.
In addition, even if the cover is strongly covered, it is possible to prevent the cover made of the synthetic resin sheet from being easily deformed.
