Description

  The present invention relates to a packaging container, and more particularly to a packaging container composed of a container main body and a lid suitable for storing cut vegetables (salad) and cut fruits.

  Vegetables, salads, and fruits are generally sold as they are, but in recent years when there are more “living alone”, those that have been subdivided (cut) have come to be preferred. . As a matter of course, a packaging container for subdividing and storing these cut vegetables (salad) and cut fruits has become necessary.

  In general, packaging containers that store cut salads and cut fruits in small portions are generally composed of a container body and a lid that are “sheet-formed” of synthetic resin sheets. There has also been a demand for things that make the contents of fruits and the like look fresh and beautiful.

  For example, Patent Document 1 proposes a packaging container that can be used to store such cut salads and cut fruits.

JP 2001-287725 A, abstract, paragraph 0001

  As described in paragraph 0001 of Patent Document 1, the “packaging container” of this Patent Document 1 is “a container body and a lid body formed of a synthetic resin film material, and the lid body with respect to the container body. Is a disposable lightweight packaging container that is mainly used to store and display small fresh food and fruits such as cherry tomatoes, kumquats, and wrinkles. As shown in FIG. 10, “the container body 1 has an outward projecting portion projecting toward the outer peripheral direction at the upper half of at least the four corners of the hanging wall, and a part of the flange edge in the outer peripheral direction. And a lower knob 15 formed so as to project inward, and the lid 2 has an inward projecting portion 24 projecting in an inner circumferential direction at a lower half portion of at least four corners of the vertical wall 22, and further, Peripheral direction of part of flange 23 It is projected and an upper knob 25 which is formed by "is intended.

  Further, as described in paragraph 0010 of Patent Document 1, the container body 1 of Patent Document 1 is “a horizontal stepped portion having a width of about 6 mm that extends toward the outer peripheral direction of the upper opening peripheral edge 10. 11, a hanging wall 12 having a width of about 7 mm hanging from the outer peripheral edge of the stepped portion 11, and a horizontal flange edge 13 having a width of about 2 mm extending from the lower end of the hanging wall 12 toward the outer periphery. A plurality of outward projecting portions 14 are formed at the four corners and each of the four sides of the hanging wall 12 and arranged in the upper half of the vertical width and projecting in the outer circumferential direction. , A lower knob 15 formed by projecting one corner portion of the flange edge 13 in the outer peripheral direction and lowering it by about 1 mm is provided.

  And, as described in paragraph 0013 of the document 1, the container body 1 of this Patent Document 1 is described as follows: “The container having such a structure puts a cherry tomato in the container body 1 by a required weight. When the lid 2 is placed on the container main body 1 and pressed lightly from above, the fitting of the lid 2 can be completed. Projections that are received by the horizontal step portion 11 and the horizontal flange portion 21 having a predetermined width in the horizontal direction, the horizontal flange edge 13 and the flange portion 23, and are formed on the vertical wall and engage in the vertical direction. 14 ..., 24 ... are acted in the direction in which their positional relations are brought into close contact with each other so that the engagement relation is not released. Pick the upper and lower knobs 15 and 25 and pull them apart. Operation has become to "shall require.

  However, in the container of Patent Document 1, as described above, “in order to open the lid body 2, an operation of picking and pulling the upper and lower knobs 15 and 25 arranged above and below is required”. In addition, when the lid 2 is suddenly removed by this pulling operation, there is a possibility that the cherry tomatoes that are the contents will jump out of the container.

  In addition, in the packaging container of this Patent Document 1, when trying to mix the dressing with the cut salad, “the horizontal step portion 11 having a width of about 6 mm and extending toward the outer peripheral direction on the upper opening peripheral portion 10 and A hanging wall 12 having a width of about 7 mm suspended from the outer peripheral edge of the step portion 11 and a horizontal flange edge 13 having a width of about 2 mm extending from the lower end of the hanging wall 12 toward the outer peripheral direction. Because it has, cut salad and dressing will spill out.

  Also, in general, cut salads and cut fruits are not packed in a container, and it is necessary to improve the appearance, so the assorted state to impress `` fun feeling '' and `` luxury '' Stored in consideration. In that respect, for example, in the case of a general container as shown in FIG. 10, there is no problem in terms of storage efficiency. It is thought that it has become a thing that needs one thought. In particular, it is necessary for containers for storing this type of cut salad and cut fruit to ensure that the assorted state does not collapse when transporting and storing each container after storing cut salad and cut fruit. It becomes.

  Therefore, the present inventors do not have cut salads and dressings, and how to make a packaging container that does not spill out or spill, and that the assorted state is difficult to collapse and can improve the appearance, As a result of various studies on the above, the present invention has been completed.

  That is, the object of the present invention is that the sheet can be molded, the contents do not pop out when the lid is opened, the spill does not occur when the dressing is mixed, and the assorted state is It is an object of the present invention to provide a packaging container that is not easily collapsed and can have a good appearance when displayed.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“A packaging container 100 that integrates the container body 10 and the lid body 20 by fitting the fitting protrusions 21 of the lid body 20 into the fitting recess 11 of the container body 10,
The packaging container 100 is characterized in that a first flare portion 12 is formed integrally with the outer edge of the outer wall 11a forming the fitting recess 11 so as to rise and spread outward.
It is.

  That is, the packaging container 100 according to claim 1 is composed of a sheet body 10 and a lid 20, and the container body 10 is indicated by a dotted line in the figure as shown in FIG. 2. The lid 20 has a fitting recess 11 where the tangent 30 shown in FIG. 4, FIG. 7 and FIG. 9 is located. It has. In this packaging container 100, the lid body 20 is integrated with the container body 10 by fitting the fitting protrusions 21 of the lid body 20 into the fitting recess 11 of the container body 10. By removing the lid 20 from the container main body 10, the cut salad and cut fruit stored in the container main body 10 can be taken out.

  And in this packaging container 100 of this Claim 1, as shown also in FIG. 2, the 1st flare part 12 is integrally formed in the outer edge of the outer side wall 11a in which the fitting recessed part 11 is formed. However, as shown in FIG. 3 (a), the first flare portion 12 rises from the outer edge of the outer wall 11a and spreads outward.

  Generally, the fitting of the lid to the container body is “inner fitting” or “outer fitting”, for example, as shown in FIG. It is performed in a portion called “flange” formed on the outer peripheral edge of the container, and this “flange” forms the outer shape of the conventional container.

  However, in the packaging container 100 according to the present invention, the fitting recess 11 of the container body 10 constituting the packaging container 100 corresponds to a “flange” of a conventional general container. A first flare portion 12 is integrally formed on the outside. In the packaging container 100 according to the present invention, the flange 16 is formed on the outer periphery of the first flare portion 12, but the flange 16 is not a portion for fitting the lid 20, but the first flare portion 12. This is to ensure the rigidity of the flare portion 12.

  As a result of the above, in this packaging container 100, as shown in FIG. 2 and FIG. 3A, at least in the container body 10, the first flare portion 12 greatly expands outside the fitting recess 11. Since the first flare portion 12 exists, the first flare portion 12 plays a role of a “sink”. That is, when the lid 20 is suddenly removed from the container body 10 and vibration is applied to the container body 10, even if the cut salad or cut fruit existing in the storage portion of the container body 10 is about to jump out, It is received by the 1 flare portion 12. Of course, since the first flare portion 12 extends upward from the outer wall 11a of the fitting recess 11, the received cut salad or cut fruit is again guided into the storage portion of the container body 10, Cut salad or cut fruit will not jump out of the container body 10.

  Moreover, since this 1st flare part 12 is expanding upward from the outer side wall 11a of the fitting recessed part 11, it not only prevents the spilling of the dressing when dressing cut salad, but also dressing This also prevents the cut salad from jumping out and spilling out of the container body 10 during the operation of mixing. Since the first flare portion 12 plays a role of a “receiver”, the cut salad that has been tightly packed in the storage portion of the container body 10 can be spread over this to make it “soft”. It can also be made with a soft texture.

  Furthermore, since this packaging container 100 has the first flare portion 12 of the container body 10 spread outward, when the container body 10 is packed with cut salad or cut fruit, it is also shown in FIG. As shown, the first flare portion 12 not only serves as a decoration for cut salad and cut fruit, but also separates the storage portion on the lid 20 side by the amount of the first flare portion 12. As a result, the assorted state is not easily broken, so that the appearance is improved.

  Moreover, since this 1st flare part 12 is a part which protruded largely outward from the side wall of the container main body 10, as shown also in FIG. It is an easy part, and the packaging container 100 can be easily moved and handled.

  And even if the container main body 10 has the 1st flare part 12, this 1st flare part 12 spreads outside from the outer side wall 11a of the fitting recessed part 11, and this packaging container 100 has it. Therefore, a so-called “undercut portion” is not generated in the container body 10 and can be molded from a synthetic resin sheet by ordinary sheet molding.

  Therefore, the packaging container 100 according to claim 1 can be formed into a sheet, and the contents do not pop out when the lid 20 is opened, and no spilling occurs when the dressing is mixed. Moreover, the assorted state is not easily broken, and the appearance at the time of display can be improved.

Moreover, in order to solve the said subject, the means which the invention which concerns on Claim 2 took about the packaging container 100 of the said Claim 1,
“The second flare portion 22 that extends on the first flare portion 12 on the container body 10 side is integrally formed on the outer edge of the ridge 21 of the lid 20.”
It is.

  That is, the packaging container 100 according to the second aspect is formed by integrally forming the second flare portion 22 also on the outer edge of the ridge 21 of the lid body 20, and the second flare portion 22 is formed as shown in FIG. As shown in FIGS. 4 and 5, it spreads on the first flare portion 12 on the container body 10 side.

  Since the lid 20 integrally formed with the second flare portion 22 covers the upper side of the cut salad or cut fruit stored in the container body 10, the second flare portion 22 formed on the lid 20 When the lid 20 is removed from the container body 10, it does not prevent the cut salad or dressing or the cut fruit from jumping out or spilling. However, since the second flare part 22 extends on the first flare part 12 on the container body 10 side, when the container body 10 is packed with cut salad or cut fruit and displayed, it is also shown in FIG. As described above, the first flare portion 12 is covered so as to prevent foreign matters from getting on the first flare portion 12 and preventing dust from adhering thereto, and also serves as a decoration for cut salad and cut fruit. As a result, it looks good.

  Further, as shown in FIGS. 4 and 5, the second flare portion 22 on the side of the lid 20 has a “fork” for eating cut salad and cut fruit on the upper surface of the packaging container 100 and the above dressing. A place can also be formed.

  And even if the lid | cover 20 has the 2nd flare part 22, the 2nd flare part 22 is the 1st flare of the container main body 10 side. Since it spreads on the part 12, what is called an "undercut part" does not generate | occur | produce in the cover body 20, but it can shape | mold from a synthetic resin sheet by normal sheet molding.

  Further, as shown in FIG. 1, the second flare portion 22 is a portion that protrudes greatly outward from the side wall of the lid 20 or the container main body 10, so that the packaging container 100 can be pinched by hand. It is a portion that is easy to hold and carry, and the packaging container 100 can be easily moved and handled.

  In the packaging container 100 according to claim 2, the flange 26 is formed on the outer periphery of the second flare portion 22, but the flange 26 fits the lid 20 into the container body 10. This is for securing the rigidity of the second flare portion 22 instead of the portion.

  Therefore, the packaging container 100 of this second aspect exhibits the same function as that of the above-mentioned first aspect, and also has a good appearance at the time of display by the second flare portion 22 and eats cut salad and cut fruit. The “fork” and the dressing place are secured.

As described above, in the present invention,
“A packaging container 100 that integrates the container body 10 and the lid body 20 by fitting the fitting protrusions 21 of the lid body 20 into the fitting recess 11 of the container body 10,
The first flare portion 12 that rises from the outside and spreads outward is integrally formed on the outer edge of the outer wall 11a forming the fitting recess 11. "
There is a main feature in the structure, of which, of course, the sheet can be molded, the content does not pop out when opening the lid 20, and no spilling occurs when mixing the dressing, In addition, it is possible to provide a packaging container 100 that is not easily collapsed and can have a good appearance when displayed.

It is sectional drawing of the container 100 for packaging which concerns on this invention. The container main body 10 which comprises the packaging container 100 is shown, (a) is a top view, (b) is the front view which made the right half the longitudinal cross-sectional view in the 1-1 line in (a). . The 1st flare part 12 currently formed in the container main body 10 of the packaging container 100 is shown, (a) is a fragmentary sectional view in the 2-2 line | wire part in a part of the container main body 10, (b) ) Is a partial cross-sectional view taken along line 3-3 in (a) when a plurality of container bodies 10 are stacked. 2 is a plan view of a lid 20 that constitutes the packaging container 100. FIG. The lid 20 which comprises the packaging container 100 is shown, and it is the front view which made the right half the longitudinal cross-sectional view. The 2nd flare part 22 currently formed in the cover body 20 of the packaging container 100 is shown, (a) is a fragmentary sectional view in a part of the cover body 20, and a 4-4 wire | line part in it, (b) ) Is a partial cross-sectional view taken along line 5-5 in (a) when a plurality of lids 20 are stacked. The container main body 10 which comprises the other example of the packaging container 100 is shown, (a) is a top view, (b) is the front view which made the right half the longitudinal cross-sectional view. The cover 20 which comprises the other example of the packaging container 100 is shown, (a) is a top view, (b) is the front view which made the right half the longitudinal cross-sectional view. The container main body 10 made into the circular view planar view of the container 100 for the packaging is shown, (a) is a top view, (b) is the front view which made the right half the longitudinal cross-sectional view. It is a perspective view which shows the prior art example described in patent document 1. FIG.

  The present invention configured as described above will be described with reference to a packaging container 100 according to the embodiment shown in the drawings. FIG. 1 shows a packaging container in which a lid 20 is fitted and integrated with a container body 10. A cross-sectional view of 100 is shown.

  The container body 10 is a synthetic resin sheet formed by vacuum or pressure forming, that is, sheet forming. As shown in FIGS. 2A and 2B, a side wall 10a rising from the periphery of the bottom surface, and the side wall 10a. The fitting recess 11 integrally formed at the upper end of the fitting recess 11 and the first flare portion 12 extending upward from the end of the outer wall 11a of the fitting recess 11 are integrally molded.

  As shown in FIG. 2B, the bottom surface of the container body 10 has a so-called raised bottom shape in which the central portion is slightly raised, and the periphery is in contact with a display shelf or the like. A plurality of ventilation portions 15 are formed around the bottom surface, and ventilation between the central portion of the bottom surface and the display shelf or the like can be performed through the ventilation portions 15. In other words, the packaging container 100 slightly raises the central portion of the bottom surface of the container main body 10 and forms a plurality of ventilation portions 15 around the bottom surface, thereby ensuring the circulation of cold air to the entire periphery. It can be done.

  Further, when looking at the side wall 10a of the container main body 10, as shown in FIG. 2A, in the corner portion (in the embodiment, it is rectangular or square in plan view, there are four corners). Is formed with a plurality of small inner ribs 13b between the large inner ribs 13a, and both the small inner ribs 13b and the large inner ribs 13a are both formed. It protrudes into the container body 10.

  These large inner ribs 13a and small inner ribs 13b are naturally formed in order to increase the rigidity of the side wall 10a, but by saying these projecting inward, cut salad and cut fruit This prevents the inner surface of the side wall 10a from contacting too much. If the cut salad or the cut fruit remains in contact with the inner surface of the side wall 10a, it may be discolored by water or may be damaged in some cases. Therefore, the large inner ribs 13a and the small inner ribs 13b are preferable. The contact with the inner surface of the side wall 10a is prevented.

  Further, as shown in FIGS. 2A and 2B, a blocking prevention portion 14 is formed on a part of the side wall 10a. This blocking prevention part 14 prevents the container main bodies 10 from fitting into each other (blocking phenomenon) as shown in FIG. 3B when a large number of the container main bodies 10 are stacked. It is. In the container main body 10 of the packaging container 100 according to the present embodiment, in order to make the anti-blocking function more effective, as shown in FIG. The protruding first step portion 12a and second step portion 12b are formed, and blocking is also prevented by these first step portion 12a and second step portion 12b.

  The first flare portion 12 having the first step portion 12a and the second step portion 12b has a fitting recess 11 of the container body 10 as shown in FIG. 1, FIG. 2, and FIG. Is formed integrally with the outer edge of the outer wall 11a so as to stand up and spread outward. The fitting recess 11 is formed over the entire inner periphery of the opening of the container body 10, and the entire periphery of the fitting protrusion 21 on the lid body 20 formed over the entire circumference can be fitted so that the packaging The container 100 can be hermetically sealed. Therefore, the 1st flare part 12 which stood up from the outer side wall 11a of this fitting recessed part 11, and spread outward spreads over the inner periphery of the opening part of the container main body 10, as shown in FIG.1 and FIG.2. It is what.

  As shown in FIG. 3A, a flange 16 is formed on the outer peripheral edge of the first flare portion 12 over the entire circumference of the first flare portion 12. The flange 16 ensures the rigidity of the first flare portion 12 itself, and unlike the general flange, the fitting protrusion 21 on the lid 20 side is not fitted. Accordingly, the extending direction of the flange 16 is different from the spreading direction of the first flare portion 12, that is, is bent downward at the tip of the first flare portion 12.

  The lid 20 fitted to the container body 10 as described above is also formed by vacuum or pressure molding, that is, sheet molding of a synthetic resin sheet, as shown in FIGS. 4 to 6. As shown in FIG. 5, the lower end of the fitting ridge 21 fitted into the fitting recess 11 on the container body 10 side forms the lower end of the lid body 20. From the outer edge of this fitting convex strip 21, the 2nd flare part 22 extended on the 1st flare part 12 by the side of the container main body 10 is formed, and the front-end | tip of this 2nd flare part 22 becomes the flange 26. .

  Since the second flare portion 22 described above extends toward the first flare portion 12 on the container body 10 side, as shown in FIG. 1, the entire first flare portion 12 on the container body 10 side As a result, the container body 10 not only deposits dirt and dust on the first flare portion 12 but also prevents the condensed water droplets from dripping directly onto the first flare portion 12. It also prevents it from flowing into.

  Further, as shown in FIGS. 1 and 4, a knob portion 27 is formed in a part of the second flare portion 22, and by using the knob portion 27, the lid body 20 can be placed in a container. The force at the time of removing from the main body 10 can be partially applied so that the cover body 20 is not suddenly released.

  In addition, about the 2nd flare part 22 of a present Example, as shown in FIG. 5, similarly to the 1st flare part 12 by the side of the container main body 10, the 1st step part 22a and 2nd which protrude alternately inside and outside A stepped portion 22b is formed, and a blocking preventing portion 24 is formed on a part of the rising wall 23a of the lid 20 as shown in FIG. These blocking prevention parts 24 and the first step part 22a and the second step part 22b prevent so-called blocking when a large number of the lids 20 are stacked, as shown in FIG. 6 (b). .

  On the other hand, as shown in FIG. 6A, the rising wall 23a rises from the inner end edge of the fitting ridge 21 in which the second flare portion 22 is integrated, and the rising wall 23a A top plate 23 is integrally formed at the tip. Of course, when the lid 20 is fitted to the container body 10 side, the top plate 23 covers the upper part of the storage part of the container body 10 as shown in FIG. As shown in FIG. 5, it protrudes slightly above the upper surface of the second flare portion 22. As described above, the top plate 23 is positioned above the second flare portion 22 in order to increase the volume in the container body 10 fitted with the lid 20, but the stored cut salad or This is to improve the appearance of the cut fruit.

  If the position of the top plate 23 is lowered to, for example, the position of the fitting ridges 21, it is natural that the amount of cut salad and cut fruit to be stored is reduced and the appearance is not good. On the other hand, if the position of the top plate 23 is set higher than the second flare portion 22, cut salad and cut fruit appear to be loose in the packaging container 100, which not only looks bad. In some cases, when the lid 20 is removed from the container body 10, the contents may be scattered or spilled. Therefore, as shown in FIG. 5, the top plate 23 is most preferably formed so as to be slightly above the second flare portion 22.

  Further, as shown in FIGS. 4 and 5, a mounting table 25 bulging slightly upward from the top plate 23 is formed at the corner of the top plate 23. Not only increases the rigidity of the top plate 23, but also places the container body 10 of the other packaging container 100 stacked above the packaging container 100 between the top plate 23 and the container body 10. It is supported with a distribution space secured. Each mounting table 25 has a shape that matches the shape of the bottom surface on the container body 10 side, and enables positioning between the packaging containers 100 when stacking a plurality of packaging containers 100. It is.

  The packaging container 100 according to the embodiment shown in FIGS. 1 to 6 exemplifies a container having a “rectangular shape” in plan view. This packaging container 100 is shown in FIGS. 7 and 8. As such, it may be implemented as “square”.

  The packaging container 100 according to the embodiment shown in FIGS. 7 and 8 is the same as that shown in FIGS. 1 to 6 except that the shape in plan view is a square. In FIG. 8, the same reference numerals as those used in the above embodiment are assigned to the same parts, and detailed description thereof is omitted.

  In the embodiment of FIG. 9, the container body 10 having a “circular” shape in plan view is illustrated, but the lid body 20 fitted to the container body 10 is also formed in a circular shape in plan view. Needless to say, the circular packaging container 100 is configured.

  As described above, the container body 10 and the lid body 20 that are “circular” in plan view have almost no directionality, which is convenient not only in manufacturing but also in use. In addition, when a large number of such circular packaging containers 100 are displayed, there are many gaps in which fingers can be inserted between the packaging containers 100. The container 100 can be taken out very easily. If the container body 10 and the lid 20 are circular in plan view, the presence of the first flare portion 12 and the like can ensure liquid-tight fitting between them.
