Description

  The present invention relates to a container in which a sheet is formed, and more particularly to a container having a bottom wall provided with a guide portion for guiding a categorization represented by chopsticks and forks.

  In recent years, various types of containers that are molded from a synthetic resin sheet are proposed because they are inexpensive and hygienic. In addition, since such sheet-formed containers and trays are disposable, they are also targets for reducing dust, and efforts have been made to reduce the thickness of the synthetic resin sheet as a material. ing.

As the thickness of the synthetic resin sheet becomes thinner, the container formed by using this as a material has to have a low rigidity, and in order to secure the necessary rigidity as a container, see Patent Document 1. As has been described, the formation of “ribs” has been performed.
Patent No. 3939837 publication

  According to the technique of the above-mentioned Patent Document 1, “the occurrence of dents and deformation of foods such as konjac” can be prevented, but it is considered that the following problems as containers for foods are not solved.

  Examples of what is stored in this type of container include “sashimi” that easily generates liquid soup and “croquette” that can be stored in a freshly fried state. “Sashimi”, which is easy to generate liquid juice, has a high possibility of a drop in taste due to being soaked in the liquid juice produced by itself for a long time. In addition, when “sashimi” is placed in a container, these “sashimi” stick to each other or to the bottom wall of the container and are removed with chopsticks or forks (hereinafter collectively referred to as cutlery). When trying to do so, it often happens that it becomes difficult to take out.

  On the other hand, in the case of “croquette”, freshly-fried food may be stored in a container, but at that time, heat may be directly transferred to a flat bottom wall surface, or excess oil may drip. Containers with a lot of “heat” transmitted may be deformed, and if the dripping oil adheres to the croquettes again, the taste of the croquettes may deteriorate. In addition, if the bottom wall is flat, when trying to remove a heavy croquette from the container with cutlery, the croquette may jump out of the container and fall to the floor due to the force received from the cutlery.

  Therefore, the present inventors have sufficient rigidity to store food, how to make a container that can be taken out by food cutlery without accidentally jumping out, As a result of various studies on the above, the present invention has been completed.

  That is, the object of the present invention is not only to have sufficient rigidity and heat resistance for storing foods, but also to prevent foods from being soaked in juice or oil, and to cut foods 30 It is an object of the present invention to provide a sheet-molded container that can be easily taken out by simple construction.

In order to solve the above problems, the means taken of this onset Ming is explained with reference numeral used in the description of the best mode described below,
“A sheet-formed container 10,
The bottom wall 11 of the vessel 10, a height of 1.0 mm to 5.0 mm, the amplitude of 5.0Mm～22.0Mm, a plurality of corrugated Li blanking 11a parallel to each other physicians, each of these wavy ribs at 11a side of the corrugated rib 11a on multiple guide the tip of the mosquito Tralee 30 to move together to form a long draft within 17, each of these proposals the unit 17 wavy ribs 11a a container 10 ", characterized in that it has to have a plane along a flat row direction.

  That is, the container 10 according to claim 1 is formed by vacuum or pressure forming (sheet forming) of a sheet material, and the plurality of wave-like ribs 11a formed in parallel to each other on a part of the bottom wall 11 as well as the entire shape. The guide portions 17 formed to guide the front ends of the cutlery 30 typified by chopsticks and forks are also formed at the same time as the sheets are formed. And each guide part 17 is formed as what has a surface along the said parallel direction.

  The container 10 according to the best mode to be described later has a rectangular shape in plan view, but the present invention is not limited to the case where the shape of the container 10 is this rectangular shape, but is a polygonal shape, circular shape, or elliptical shape in plan view. Any of these can be targeted. This is because the corrugated rib 11 a and the guide portion 17 may be formed on the bottom wall 11 in any of the planarly shaped containers 10.

  The corrugated rib 11a may be in various forms as shown in FIGS. 10 to 15, but the basic configuration thereof is that of the container 10 as shown in FIG. 1 and FIG. 2A, or FIG. 7 and FIG. A part of the bottom wall 11 is the corrugated rib 11a, it is parallel to each other, and a guide portion 17 for guiding the tip of the cutlery 30 is present on the side of each corrugated rib 11a. .

  “Parallel” in the case where the plurality of wave-like ribs 11a are formed in parallel to each other means that the wave-like ribs 11a are parallel to the straight side wall 15 of the rectangular container 10 as shown in FIG. 2A. Needless to say, it is curved or bent when viewed straight, but includes the case where the distance between them is the same, that is, the case where each corrugated rib 11a is curved or bent.

  Further, when the wavy ribs 11a parallel to each other are literally considered as “waves”, the height, amplitude, and width can be considered, but the height is preferably in the range of 1.0 mm to 5.0 mm. . This is because if the height of the corrugated rib 11a is lower than 1.0 mm, the rigidity by the corrugated rib 11a is hardly different from the case of the flat bottom wall 11, and it is difficult to ensure the rigidity. In particular, it is preferable to set the thickness within a range of 3.0 mm to 4.0 mm.

  The amplitude of the wavy rib 11a is preferably 5.0 mm to 22.0 mm. This is because if the amplitude of the wavy rib 11a is smaller than 5.0 mm, the “lumpy feeling” when the cutlery 30 is slid is increased, and if it is larger than 22.0 mm, it is difficult to ensure rigidity. When the thickness is 0.0 mm to 15.0 mm, the effect is high. In relation to this amplitude, if the radius of the outer curved surface of each corrugated rib 11a is 3.0 mm to 15.0 mm, particularly 6.0 mm to 10.0 mm, the corrugated rib 11a can be made more effective. it can.

  On the other hand, the guide portion 17 for guiding the tip of the cutlery 30 may be of various forms as shown in FIG. 16 or FIG. 17, but its basic configuration is formed on the side portion of each corrugated rib 11a. That is, it has a surface along the parallel direction of the wavy rib 11a.

  What is important is that there are two kinds of modes as the guide portion 17. First, as shown in FIGS. 1 and 2A, when the guide portion 17 is formed as a “rib” that rises on the bottom wall 11 (in this case, the guide portion 17 has a convex shape in plan view). 7 and FIG. 8, the second case is a case where a “wall” is formed by a part of the bottom wall 11 on the side portion of the wave-like rib 11 a. In either case, the corrugated ribs 11a are located on the sides of the corrugated ribs 11a and have a surface along the parallel direction of the corrugated ribs 11a. As shown in FIG. 6 or FIG. The tip of the cutlery 30 represented by chopsticks and forks is guided.

  It is conceivable that the guide portion 17 is formed as a “rib” that bulges from the bottom wall 11 to the bottom side (in this case, the guide portion 17 is a concave groove in a plan view). A portion formed as a “wall” by a part of the bottom wall 11 on the side of 11a or a concave groove of the guide portion 17 serves as a guide portion at the tip of the cutlery 30 and swells downward from the bottom wall 11. The “guide portion 17” to be brought out mainly contributes to securing rigidity.

  In the case where the first guide portion 17 is formed as a “rib” that rises at the bottom wall 11, the surfaces along the parallel direction (surfaces that the cutlery 30 actually hits) are various as shown in FIG. 16. The thing which becomes a various aspect can be considered. Further, as the cross-sectional shape of each guide portion 17 as a “rib”, various forms as shown in FIG. 17 are conceivable.

  In the case of forming as a “wall” by a part of the bottom wall 11 on the side portion of the second corrugated rib 11a, there are various modes as shown in FIGS. Conceivable. Of course, in this case where each guide portion 17 is formed as a “wall”, this “wall” is formed by a part of the bottom wall 11, and therefore, as shown in FIG. A predetermined interval is required. The distance is preferably about 0.5 mm to 3.0 mm in consideration of “sheet molding”.

  Now, in this container 10 in which the above-described corrugated ribs 11a and guide portions 17 are formed, the bottom wall 11 has a plurality of corrugated ribs 11a formed thereon, and guides formed on the side portions of these corrugated ribs 11a. It is reinforced by the part 17. This is because each corrugated rib 11a and the guide part 17 form a surface perpendicular to the direction of force for bending the container 10 (particularly the bottom wall 11 thereof).

  In particular, the presence of a plurality of the wavy ribs 11a in a row makes the valleys of the wavy ribs 11a also serve as storage portions for relatively small foods such as chili jam cucumbers and pickles, and makes it difficult for the stored items to deviate from the storage position. For this reason, for example, when the container 10 storing the stored items is transported or displayed on an inclined display shelf, the stored items enter the valleys of the corrugated ribs 11a. There is no misalignment.

  In addition, the upper surface of the guide portion 17 when the corrugated ribs 11 a are formed as “mountains” or ribs not only supports the stored food with “lines” but also slightly floats from the bottom wall 11. I will support it. For this reason, not only does the heat from the freshly fried "croquettes" be transmitted to the bottom wall 11, but also supports these foods without immersing them in the juice from "sashimi" or the oil dripping from "croquettes". It becomes.

  Of course, each guide part 17 can guide the tip of the cutlery 30, and the food stored in the container 10 can be easily taken out. That is, as shown in FIG. 6 or FIG. 9, if the tip of the cutlery 30 is brought into contact with the wavy rib 11a and is slid toward the lower side of the stored item such as “sashimi” or “croquette”, Since the leading end of the cutlery 30 is guided by each guide portion 17, the leading end of the cutlery 30 does not move carelessly, and the food to be taken out does not spill from the container 10.

  Moreover, since the tip of the cutlery 30 slides on the surface of the wave-like rib 11a that is waved, it moves up and down slightly according to the wave of the wave-like rib 11a. By this vertical movement, for example, “sashimi” sticking to each other is peeled off, so that “sashimi” can be easily grasped and food can be easily taken out.

  Furthermore, even if a stored item (food item) is clogged between the guide portions 17, the clogged food product can be removed from the cutlery 30 by moving the tip of the cutlery 30 between the guide portions 17. It can be easily removed at the tip.

  Therefore, the container 10 according to the present invention has not only sufficient rigidity and heat resistance for storing food, but also prevents the food from being soaked in juice or oil, and easy removal of the food by the cutlery 30. It has become something that can be done.

As described above, in the present invention,
“A sheet-formed container 10,
The bottom wall 11 of the vessel 10, a height of 1.0 mm to 5.0 mm, the amplitude of 5.0Mm～22.0Mm, a plurality of corrugated Li blanking 11a parallel to each other physicians, each of these wavy ribs at 11a side of the corrugated rib 11a on multiple guide the tip of the mosquito Tralee 30 to move together to form a long draft within 17, each of these proposals the unit 17 wavy ribs 11a flat row as the the to have a plane along a direction "to have features on its configuration, which not only has sufficient rigidity and heat resistance as for storing food, food Ya soup It is possible to provide the sheet-formed container 10 that can be prevented from being soaked in oil and that can be easily taken out by the cutlery 30 with a simple configuration.

  Further, according to the present invention, since a plurality of the wavy ribs 11a are arranged in a row, the valleys of the wavy ribs 11a also serve as storage portions for relatively small foods such as chili jam cucumbers and pickles, and the stored items are stored in the storage positions. Can be made difficult to shift. For this reason, for example, when the container 10 is transported or displayed on an inclined display shelf, the stored items are displaced greatly by being in the valleys of the wavy ribs 11a. It is possible to display products (contained items) neatly.

  Next, the present invention configured as described above will be described with respect to the container 10 which is the best mode shown in the drawings. In FIG. 1 and FIG. 7, the lid 20 is fitted on the container 10 according to the best mode. This state is shown in a sectional view.

  Both the container 10 and the lid 20 are formed by vacuum or pressure molding using a synthetic resin sheet as a material. The thickness of the synthetic resin sheet used in the best mode is 0.1 mm to 2.0 mm. It is. When the thickness of the synthetic resin sheet is less than 0.1 mm, the container 10 can be used for reducing the amount of dust, but the designed wave-like ribs 11a and guide portions 17 cannot be formed by the above sheet molding. Further, when the thickness of the synthetic resin sheet is greater than 2.0 mm, the container 10 cannot be used for reducing the amount of dust, and depending on the sheet molding, the corrugated rib 11a and the guide portion 17 as designed may be used. Cannot be formed. In summary, the thickness of the synthetic resin sheet used is preferably 0.3 mm to 0.5 mm.

  The best shape of the container 10 shown in FIG. 1 is a rectangular shape, but the present invention is applicable to other shapes such as a polygonal shape, a circle, an ellipse, etc. Is something that can be done.

  As shown in FIG. 2A or FIG. 8, the container 10 has a bottom wall 11 on which a stored item (a sashimi or croquette or other food) is placed in a substantially rectangular shape in plan view. In the best mode, a fitting flange 15a to which the fitting flange 21 on the lid 20 side is fitted is formed at the upper part of the side wall 15 formed around the periphery. In other words, the container 10 may be used alone so as to be wrapped with a wrap in a state in which a stored item is put, or may be used by fitting the lid 20.

  In the container 10, as shown in FIG. 6 or 9, a plurality of corrugated ribs 11a parallel to each other are formed on the bottom wall 11, and the tip of the cutlery 30 is formed on the side of each corrugated rib 11a. Guide portions 17 are formed, and these guide portions 17 have a surface along the direction of the wavy rib 11a.

  That is, in the example shown in FIG. 2A, a plurality of rib-shaped guide portions 17 extending in the long side direction are formed on the bottom wall 11 of the container 10 according to the best mode. A wave-like rib 11 a is formed between the layers 17. Moreover, in the example shown in FIG.7 and FIG.8, the several wave-like rib 11a extended in a long side direction is formed so that the vertex of the peak part may correspond with the inner surface of the bottom wall 11, and these As shown in FIG. 7, the portion that becomes the side portion of each of the wavy ribs 11 a is a guide portion 17.

  What is important about the guide portion 17 is that the guide portion 17 has two types of modes. The first is a case where the guide portion 17 is formed as a “rib” that rises on the bottom wall 11 as shown in FIGS. 1 and 2A, and the second is shown in FIGS. 7 and 8. Thus, it is a case where it forms as a "wall" by a part of bottom wall 11 in the side part of the wavy rib 11a.

  In the case where the first guide portion 17 is formed as a “rib” that rises at the bottom wall 11, the surfaces along the parallel direction (surfaces that the cutlery 30 actually hits) are various as shown in FIG. 16. Can be made. Further, the cross-sectional shape of each guide portion 17 as a “rib” can be in various forms as shown in FIG.

  In the case where the second wall is formed as a “wall” by a part of the bottom wall 11 on the side portion of the corrugated rib 11a, it has various modes as shown in each of FIGS. Can be considered. Of course, in this case in which each guide portion 17 is formed as a “wall”, this “wall” is formed by a part of the bottom wall 11, and therefore, as shown in FIG. Further, an interval of about 0.5 mm to 3.0 mm is provided.

  The corrugated ribs 11a may be in various forms as shown in FIGS. 10 to 15, but the basic configuration thereof is a container as shown in FIGS. 1 and 2A, or FIGS. That is, a part of the bottom wall 11 of 10 is made into the corrugated rib 11a, it is made parallel to each other, and the guide portion 17 for guiding the tip of the cutlery 30 is present on the side of each corrugated rib 11a.

  “Parallel” in the case where the plurality of wave-like ribs 11a are formed in parallel to each other means that the wave-like ribs 11a are parallel to the straight side wall 15 of the rectangular container 10 as shown in FIG. 2A. Needless to say, it is curved or bent when viewed straight, but includes the case where the distance between them is the same, that is, the case where each corrugated rib 11a is curved or bent.

  In addition, when the wavy ribs 11a parallel to each other are literally considered as “waves”, the height, amplitude, and width are conceivable. In the best mode, the height is set within a range of 3.0 mm to 4.0 mm. It is. The amplitude of the corrugated rib 11a is preferably 5.0 mm to 22.0 mm, but in the best mode, the amplitude is 10.0 mm to 15.0 mm. In relation to this amplitude, if the radius of the outer curved surface of each corrugated rib 11a is 3.0 mm to 15.0 mm, particularly 6.0 mm to 10.0 mm, the corrugated rib 11a can be made more effective. it can.

  Moreover, in each wave-shaped rib 11a which concerns on the best form shown in figure, as shown, for example in FIG. 2A, the part applicable to the "mountain" of each wave is formed so that it may shift | deviate from that of the adjacent wave-shaped rib 11a. For this reason, the “wave crest” in each wave-like rib 11 a is positioned at random, so that the bottom surface 11 can be reinforced without directionality.

  On the other hand, the guide portion 17 for guiding the tip of the cutlery 30 may be in various forms as shown in FIG. 16 or FIG. 17, but its basic configuration is formed on the side portion of each of the corrugated ribs 11a. In other words, the corrugated rib 11a has a surface along the parallel direction.

  When the upper surface of each guide portion 17 is formed to be higher than the “mountain” of each corrugated rib 11a as shown in FIG. Reinforcement can be performed more firmly than, for example, only the bottom wall 11 or the case of using the corrugated rib 11a.

  As shown in FIGS. 2A and 8, legs 12 are formed at each corner of the bottom wall 11 constituting the container 10 (the total is four because it is rectangular). . Each leg 12 may be formed and implemented as an independent one at each corner, and the adjacent legs 12 are continuously formed in a “U” shape. You may form and implement.

  In the container 10 of the best mode, a plurality of vertical ribs 18 are formed inside the side wall 15 facing each leg 12 as shown in FIGS. 2A and 8. Each of the vertical ribs 18 is formed to have a flat upper end surface in addition to increasing the rigidity of each corner portion of the container 10, so that the corner ribs 22 on the lid 20 side are formed on the upper end surface. The lower surface (also formed on a flat surface) can be placed. In other words, the container 10 of the best mode is one in which the lid 20 is fitted, but another container 10 fitted with the lid 20 is placed (stacked) on the lid 20 of the container 10. In some cases, the vertical ribs 18 on the container 10 side and the corner ribs 22 on the lid 20 side come into contact with each other, so that the lid 20 and the corner ribs 22 serve as a “column” or “base”. Thus, the lid 20 and the container 10 are prevented from being crushed.

  Now, only the first reinforcing rib 13 is formed on the bottom wall 12a of each leg portion 12 facing the vertical ribs 18, or as shown in FIGS. 2B and 8, the first reinforcing rib 13 and the third reinforcing rib 13 are formed. The reinforcing ribs 16 are formed, or the first reinforcing ribs 13 and the second reinforcing ribs are formed.

  The first reinforcing rib 13 is formed on a part of the bottom wall 12a of the leg part 12 and has a bent part 13a. The second reinforcing rib has the leg part 12 on a part of the bottom wall 12a. In the case of having the bent portion 12b, the bent portion 12b is formed so as to cross the diagonal line 12c. The third reinforcing rib 16 is formed on the bottom wall 12 a of the leg portion 12 and is orthogonal to the side wall 15 surface of the container 10.

  The first reinforcing rib 13 needs to have a bent portion 13a, but various shapes can be applied as the shape of the bent portion 13a. In the case of this best mode, the bent portion 13a of each first reinforcing rib 13 is on the diagonal line 12c of the leg portion 12. However, the position of the bent portion 13a is not necessarily on the diagonal line 12c. Each diagonal line 12c passes through each vertex if the container 10 has a square shape, rectangular shape or polygonal shape in plan view, and the center of the leg 12 if the container 10 has a circular shape in plan view. Become a line.

  The shape of each bent portion 13a includes “orthogonal type”, “V-shaped type”, and “U-shaped type”. In the “U-shaped type”, the two first reinforcing ribs 13 are brought into contact with the tip of each bent portion 13 a, the tips of the respective bent portions 13 a of each first reinforcing rib 13 are separated, or the first at the tip. It is possible to form empty portions where the reinforcing ribs 13 do not exist.

  On the other hand, each of the second reinforcing ribs crosses the diagonal line 12c of the bottom wall 12a, and each diagonal line 12c has a rectangular shape, a rectangular shape, or a polygonal shape if the container 10 is a plan view. If the container 10 has a circular shape in plan view, the diagonal line passing through the apex is a diagonal line of the leg 12. The second reinforcing rib as described above can also be implemented as crossing the diagonal line 12c.

  Now, the lid 20 is fitted to the container 10 as described above. As shown in FIGS. 18 to 20, the fitting is to be fitted to the fitting flange 15 a on the container 10 side from above. The flange 21 is formed at the lower end of the side wall of the lid body 20. As shown in FIGS. 1, 7 and 19, the side wall of the lid 20 is formed to have a height higher than the side wall 15 on the container 10 side. In addition to being sufficient, visual recognition from the outside of the stored item is facilitated.

  Further, as shown in FIGS. 18 to 20, corner ribs 22 whose outer end surfaces are inclined from the end of the top plate toward the fitting flange 21 are formed near the corners of the side wall of the lid 20. is there. As described above, each corner rib 22 has a flat bottom surface. This bottom surface is a flat top of the vertical rib 18 on the container 10 side when the lid 20 is fitted to the container 10. It comes into contact with the end face.

  Therefore, when the lid 20 is fitted to the container 10 of the best mode, when another container 10 fitted with the lid 20 is placed (stacked) on the lid 20 of the container 10. In addition, as described above, the vertical ribs 18 on the container 10 side and the corner ribs 22 on the lid 20 side come into contact with each other, so that the lid 20 and the corner ribs 22 are “columns” or “bases”. The vertical ribs 18 on the side of the container 10 and the corner ribs 22 on the side of the lid 20 prevent the lid 20 and the container 10 from being crushed.
