[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, a packaging container according to the present embodiment is a tray for stably storing two not-shown Japanese sweets side by side. 1 and a lid 20 which is removably tightly fitted on the tray 1.
[0010]
The tray 1 is formed by forming a non-polluting thin synthetic resin sheet that does not generate harmful substances such as dioxin, for example, a PPF sheet, a PET sheet, a PVC sheet, and a PP sheet by vacuum (pressure) molding. , Is formed into a bottomed cylindrical shape lower than the lid 20, and is colored (for example, white or black) so as to make the Japanese confectionery stand out. As shown in FIG. 1, the tray 1 having excellent flexibility and elasticity is formed in a substantially rectangular plane with four rounded corners and a substantially groove-shaped cross section. A partition body 3 having a substantially inverted U-shaped cross section for dividing the internal storage space 2 into two in the direction is integrally formed so as to protrude.
[0011]
As shown in FIG. 1, the bottom surface of the tray 1 is divided into two patterns 4 each consisting of a plurality of continuous waves that create an aesthetic balance, a sense of luxury, a clean feeling, etc. It is formed, and irregularities are formed between each bottom surface and the pattern 4. As shown in FIGS. 1 and 2, a folded outer wall 6 that extends outward and is folded downward is flat and short connected to the upper end of the peripheral wall 5 that forms the front, rear, left and right of the tray 1 and extends horizontally outward. A shoulder shoulder 8 that supports the lower end of the inclined peripheral wall 5 of the lid 20 is formed by being bent outward at substantially the center of the folded outer wall 6 in the vertical direction, and is provided continuously with the wall 7 interposed therebetween. A bulging wall 9 bulging outward is formed below the folded outer wall 6 in the vertical direction, and a rib-shaped retaining stopper 10 is provided at a predetermined interval in the circumferential direction including the four corners of the folded outer wall 6. Are arranged integrally.
[0012]
The upper end 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 retaining stopper 10 is integrally formed on the upper portion of the folded outer wall 6 of the tray 1 and gradually inclines while gradually expanding as it goes from the opening direction (upward direction) to the bottom direction (downward direction) of the tray 1. , And a first bent side 12 which is provided at the lower end of the first sloped side 11 and is bent inward of the tray 1 and the folded outer wall 6. A coating (not shown) for preventing wear is selectively applied to the surface of each retaining stopper 10.
[0013]
The lid 20 is particularly easy to recycle, and is a non-polluting thin synthetic resin sheet that does not generate harmful substances such as transparency and dioxin, specifically, A-PET, PPF sheet, PET sheet, PVC sheet, PP Vacuum (pressurized) molding is performed using a sheet made of the material. As shown in FIGS. 1, 3 to 6, the lid 20 having excellent flexibility and elasticity is formed in a substantially rectangular flat truncated pyramid shape having four corners vertically chamfered, and an open bottom surface. It is wide and the ceiling is narrow, and it is transparent so that the state of the Japanese confectionery can be grasped. The lid 20 has a thick ceiling and a thinly inclined peripheral wall, and has a bundling process so that the inner surface is not fogged. Stop holes 22 are integrally provided at predetermined intervals.
[0014]
A part of a pair of wide and long inclined peripheral walls of the lid body 20 is formed to bulge outward, and a part between the part and the remaining part is formed in a semicircular shape in a side view (FIGS. 1, 3, and 4). reference). As shown in FIG. 3, a bent wall 21 that is slightly concave while drawing a gentle curve inward is formed integrally with the pair of narrow and short inclined peripheral walls of the lid body 20 in the vertical direction. 21 exerts a spring function and a restoring function when the lid 20 is fitted.
[0015]
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 20 at another angle and facing the first inclined side 11 from outside. The overlapping second inclined side 23 is connected to the lower end of the second inclined side 23 which gradually expands and inclines, turns inward of the lid 20, and faces the first bent side 12 from the outside. The second bent side 24 overlaps with the second bent side 24. A paint (not shown) for preventing wear is selectively applied to each retaining hole 22.
[0016]
In the above configuration, when packaging Japanese confectionery, a plurality of Japanese confections are arranged and supported on the bottom surface in the tray 1, and the lid 20 may be pushed down from above into the opening of the tray 1 to fit tightly. At this time, the lid body 20 is smoothly slid and guided without sticking to the first inclined side 11 of the retaining stopper 10, so that the lid body 20 is gradually lowered and spreads outward in the horizontal direction of the tray 1. The second bent side 24 fits and locks on the first bent side 12, and the second inclined side 23 overlaps with the first inclined side 11. As a result, the lower end of the lid 20 is supported by the shoulder shoulder 8 of the tray 1, and a plurality of Japanese confections are packaged.
[0017]
According to the above configuration, when the lid 20 is tightly fitted, the bent wall 21 that is bent extremely inwardly to the inside exerts a spring function, so that the pressing force is appropriately transmitted to the lid 20 from above to below vertically, and the lid 1 The body 20 can be fitted smoothly and easily. Therefore, since a strong fitting force is not required, the thickness of the tray 1 and the lid 20 can be reduced, and a reduction in manufacturing cost and weight can be greatly expected. Further, since the flexible bent wall 21 exhibits a restoring function, even if the lid 20 made of a thin synthetic resin sheet is fitted somewhat firmly, the partially collapsed lid 20 can be easily restored to the original form. can do. Therefore, even when high-quality Japanese confectionery is stored, the aesthetic balance, luxury, cleanliness, and the like created by the high-quality Japanese confectionery and the packaging container are not broken, and the sales promotion function is not reduced.
[0018]
In addition, the retaining stopper 10 of the tray 1 is not a simple semi-oval cross section, and the first inclined side 11 having a guiding function is partially formed in an inclined manner. It doesn't stick or hit by collision. Therefore, without using a strong fitting force, the lid 20 can be smoothly and tightly fitted to the tray 1 without resistance while securing the difficulty of removal, and the tray 1 and the lid 20 are deformed to deteriorate the appearance. No damage or damage. Furthermore, if the patterns 4 are formed on the bottom surface of the tray 1 and the bottom surface and the patterns 4 are made to have an uneven relationship, the Japanese confectionery will not be displaced and collapsed in the lateral direction due to frictional force.
[0019]
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 sections in the longitudinal direction at the inner bottom of the tray 1. Inverted U-shaped partitioning bodies 3 are integrally arranged side by side, and a pattern 4 consisting of a plurality of continuous waves that creates an aesthetic balance, luxury, cleanliness, etc. between the three divided bottom surfaces and Japanese confectionery. Are integrally formed. The other parts are basically substantially the same as those of the above-described embodiment, and thus description thereof is omitted.
In the present embodiment, the same operation and effect as those in the above embodiment can be expected, and it is clear that more Japanese confectionery can be packed.
[0020]
In addition, the folded outer wall 6 of the above embodiment may be vertically folded outwardly downward from the upper end of the peripheral wall 5, or may be folded while being inclined outwardly downward. Further, it is also possible to form the center of the peripheral wall 5 and the folded outer wall 6 low, and to form the left and right sides high. Further, the second inclined side 23 may be formed while a part of the lower part of the inclined peripheral wall of the lid 20 is inclined at the same angle.
[0021]
【The invention's effect】
As described above, according to the present invention, there is an effect that the lid can be relatively easily covered on the tray. Further, even if the lid is strongly covered, it is possible to prevent the lid made of the synthetic resin sheet from being easily deformed. In addition, since the flexible bent wall exerts a restoring function, even if the lid is slightly covered, the partially collapsed lid can be easily restored to the original shape. Furthermore, since the first inclined side having the guide function is partially formed in each retaining stopper, it is possible to prevent the retaining hole from strongly colliding with the retaining stopper and sticking or catching.
