Description

  The present invention relates to a container, and more particularly to a container that can easily combine articles contained in separate containers.

  In recent years, the variety of foods and drinks sold at convenience stores and the like is extremely diverse, and has spread to salads, desserts, noodles, and other processed foods in addition to side dishes, lunch boxes and sandwiches. When such food is sold, a container in which a lid is superimposed on a container body made of a synthetic resin sheet is often used.

  Among the foods listed, it is common for boxed foods to be packaged and sold with all ingredients in one container. This is because the tastes of the ingredients to be packed together are well adapted, and the processing and cooking methods exhibit a delicious taste as a whole. Moreover, it is because the moisture content rate of the foodstuff used is comparatively uniform. On the other hand, in the case of noodles such as buckwheat noodles, udon, and pasta, the noodles may be combined with the ingredients placed on the noodles at the time of manufacture. However, there may be a difference between the noodles and the moisture content of the ingredients placed thereon. For this reason, it is already in a state where it has already become hot when eating, and the taste tends to deteriorate. In recent years, there has been an increasing demand for taste, and this is a problem that cannot be ignored for retailers and sellers in order to differentiate themselves from other vendors and obtain customer satisfaction.

  Therefore, as a relatively simple countermeasure, there is a container using a middle dish (inner lid) in a container including a container body and a lid (for example, Patent Document 1). According to the container of Patent Document 1 or the like, for example, noodles are accommodated in the lowermost part of the container, an intermediate dish is placed thereon, an appropriate food is placed thereon, and the lid is covered at the end. In the case of the container of Patent Document 1 or the like, it is possible to suppress the mixing of ingredients before eating and bring them closer to the fresh taste. In addition, since the topped ingredients are arranged on the inner plate, the appearance is gorgeous.

  However, in the case of the container of Patent Document 1 or the like, it is not easy and time-consuming to move the food on the middle dish to the container body side, but rather it is annoying to the consumer, such as giving the consumer trouble. There is also a risk of letting it go. It takes time and effort as the number of food items subdivided on the middle plate increases. Further, in addition to the container main body and the lid that are indispensable as a container, an intermediate dish and the like are newly added, and therefore, an increase in the materials constituting the container becomes a new problem. This increases the material cost. Furthermore, consideration should be given to the flow of resource saving.

Utility Model Registration No. 3133098

  The present invention has been made in view of the above points, and separately holds the articles accommodated in the container, eliminates the complexity of the work of mixing at the time of use, and further reduces materials and saves resources. The container which makes possible is also provided.

  That is, the invention according to claim 1 is capable of peeling the lower container body whose upper surface is open to form an opening edge, and the housing concave portion for housing the article on the upper surface, and the protective film portion covering the housing concave portion can be peeled off. The lower container is provided with an engaging portion that is combined with the opening edge at a normal position, and is placed on the upper portion of the lower container body. The present invention relates to a container having an upper container body placed on an upper part of the body.

And a reversing engagement portion that is mounted on the upper portion of the lower container body in a normal position and is combined with the opening edge portion in a reversing position. Since it has an upper container body placed on the upper part of the lower container body, while holding the articles accommodated in the container individually, it eliminates the complexity of the work of mixing at the time of use, and further reduces the materials Resource saving can also be achieved.

  According to the container of the second aspect of the invention, in the first aspect of the invention, since there are a plurality of the accommodating recesses, the types of articles that can be combined with the articles accommodated in the lower container can be increased.

  According to the container which concerns on invention of Claim 3, in the invention of Claim 1 or 2, since the said protective film part is stuck by the said upper container body by heat seal, the foreign material at the time of sticking a protective film part There is very little risk of contamination and safety is high.

  According to the container of the invention of claim 4, in the invention of any one of claims 1 to 3, since the protective film part is provided with a tension member, the protective film part can be smoothly put into the upper container body without failure. Can be peeled off.

It is a perspective view which decomposes | disassembles and shows the whole container which concerns on one Example of this invention. It is a partial enlarged plan view of a container. It is a whole perspective view of a protective film. It is an expanded sectional view of the normal position of the upper container body in the XX line of FIG. It is an expanded sectional view of the inversion position of the upper container body in the XX line of FIG. It is 1st sectional drawing which shows the usage condition of the container of an Example. It is 2nd sectional drawing which shows the usage condition of the container of an Example. It is 3rd sectional drawing which shows the usage condition of the container of an Example. It is a 4th sectional view showing the use mode of the container of an example. It is 5th sectional drawing which shows the usage condition of the container of an Example.

  The container 1 defined in the invention including claim 1 is in the lower container body 10 and the upper part of the lower container body 10 in any of the normal position and the inverted position as shown in the exploded perspective views of FIG. The upper container body 30 which can be mounted and the protective film part 50 which protects the upper container body 30 are provided. In the figure, both the lower container body 10 and the upper container body 30 have an octagonal shape in which long sides and short sides are alternated in plan view. In addition, the shape of the lower container body 10 and the upper container body 30 is not restricted to illustration, and is suitable, and the form by which the junction part of edge | sides was chamfered in the curved shape is also contained.

  In the container 1, the lower container body 10 and the upper container body 30 excluding the protective film portion 50 are made of a thermoplastic resin sheet (synthetic resin sheet) such as polyethylene, polypropylene, polystyrene, and polyethylene terephthalate, and further biodegradable such as polylactic acid. It is formed from a sheet of thermoplastic resin. The synthetic resin sheet is formed into various shapes such as illustrated by vacuum forming. Although the thickness of the synthetic resin sheet is appropriate, it is approximately 1 mm or less. In the combination of the lower container body 10 and the upper container body 30, the raw material resins of the synthetic resin sheet may be the same type or different types. The type of resin is appropriately selected depending on the application, contents, and packaging target. In addition, either or both of the lower container body 10 and the upper container body 30 can be manufactured from paper or other flexible materials.

  As for the lower container body 10, the upper surface 11 opens and the opening edge part 12 is formed. A bent wall portion 13 that is folded back from the opening edge portion to the outside of the lower container body is formed at the opening edge portion 12. The inner side of the lower container body of the opening edge 12 is an inner peripheral wall portion 17. In the lower container body 10, a lower container wall 15 and a lower container bottom 16 are arranged immediately below the upper surface 11 to form a lower container body interior 14, thereby forming a container structure. Since the illustrated lower container body 10 has an irregular octagonal shape in plan view, it is a combination of the lower container corner 18 and the lower container side 19.

  In the drawing, it is assumed that the lower container body 10 is used for storing a single type of article (food) such as noodles and cooked rice. Therefore, the lower container body 10 is a single lower container body interior 14. When it is intended to accommodate a plurality of types of articles (foodstuffs) in the lower container body interior 14, a partition part (not shown) for partitioning the container body interior may be provided in the lower container wall part or the lower container bottom part.

  On the upper surface 31 of the upper container body 30, an accommodation recess 34 for accommodating an article such as a foodstuff is disposed. In the illustrated upper container body 30, as defined in the invention of claim 2, a plurality (five places) of the accommodating recesses 34 are provided. The first receiving recess 34a, the second receiving recess 34b, the third receiving recess 34c, the fourth receiving recess 34d, and the fifth receiving recess 34e are clockwise in the drawing. The housing recess 34 is formed in a concave shape by the housing inner wall 35 and the housing bottom 36. Corresponding to the first to fifth housing recesses, the first housing inner wall 35a, the second housing inner wall 35b, the third housing inner wall 35c, the fourth housing inner wall 35d, and the fifth housing inner wall in the clockwise direction in the drawing. 35e, a first receiving bottom 36a, a second receiving bottom 36b, a third receiving bottom 36c, a fourth receiving bottom 36d, and a fifth receiving bottom 36.

  Since there are a plurality of housing recesses 34 as in the upper container body 30, the types of articles combined with the articles housed in the lower container body 10 (lower container body interior 14) can be increased. In particular, when the article is a food product, it is possible to combine ingredients with various tastes and textures, so that the appearance and taste after completion can be enhanced.

  The protective film unit 50 is attached (attached) to the upper surface 31 of the upper container body 30. Therefore, the housing recess 34 (the first housing recess 34a to the fifth housing recess 34e) is covered. Articles such as foodstuffs stored in the storage recess 34 are partitioned from the outside of the upper container body 30 and protected. As will be described later, the protective film portion 50 can be peeled from the upper container body 30. In the figure, reference numeral 51 is a film body, and 52 is a tension member (detailed later).

  A peripheral wall 39 is formed around the upper surface 31 of the upper container body 30. A peripheral edge 32 is formed at a position one step below the upper surface 31 via the peripheral wall 39. Then, a hanging wall portion 33 surrounding the outer edge of the peripheral edge portion 32 is formed. The illustrated upper container body 30 is also provided with an operation portion 20 that is integrated with the peripheral edge portion 32 and the hanging wall portion 33. The operation unit 20 includes a hemispherical knob portion 21, and includes a hollow portion 22 in the knob portion 21. The operation unit 20 is used when removing the upper container body 30 from the lower container body 10. In the figure, reference numeral 37 denotes a reverse engaging portion, and 38 denotes an engaging portion (detailed later).

  FIG. 2 is a partially enlarged plan view of the container 1, wherein the upper container body 30 is a solid line, the lower container body 10 is a thin broken line, and the protective film part 50 is a thin two-dot chain line. The vicinity is enlarged. When the protective film part 50 and the upper container body 30 are attached, as long as an appropriate adhesive strength can be secured between them, the protective film part 50 and the upper container body 30 can be attached using an adhesive, a double-sided tape, or the like. However, taking into account that the article contained in the container 1 of the present invention is food (foodstuff), the protective film portion 50 is attached to the upper container body 30 by heat sealing as defined in the invention of claim 3. . Adhesion by heat sealing does not use an adhesive, a double-sided tape or the like, and the adhesion between the protective film portion 50 and the upper container body 30 is completed by heating a predetermined portion. For this reason, there is very little possibility of foreign matter mixing at the time of sticking, and safety is high.

  In the upper container body 30, the part marked with “*” on the upper surface 31 is the heat seal attachment part 40. The protective film part 50 is piled up on the heat seal sticking site | part 40, and heat seal sticking is implemented by a suitable heat sealer. If the heat seal strength between the protective film part 50 and the upper container body 30 is extremely high, the protective film part 50 cannot be peeled off from the upper container body 30 successfully. Further, if the heat seal strength is too weak, the protective film portion 50 is easily peeled off from the upper container body 30 and is not useful for protecting the article accommodated in the interior of the accommodation recess 34. Therefore, selection of an appropriate heat seal application site, setting of heat seal strength, and further, a resin type and structure for forming a film body of the protective film portion are selected. The film body 51 is composed of a known heat seal film having cohesive fracture properties and interlayer fracture properties.

  The protective film portion 50 of the present invention will be further described with reference to the overall perspective view of FIG. When the protective film part 50 is peeled from the upper container body 30 during eating, the film body 51 can be simply pulled out of the upper container body 30. However, in addition to the film body 51 being caught on the upper surface 31 during the pulling out, the film body itself may be broken. For this reason, as defined in the invention of claim 4, in the protective film unit 50, the film body 51 is provided with the tension member 52. The protective member 50 can be smoothly peeled from the upper container body 30 without failure by the tension member 52. The tension member 52 is made of an appropriate belt-like film. As will be described later, the tension member 52 is pulled after the upper container body 30 is turned to the inverted position. Therefore, the tension member 52 is convenient because it is a thin film and does not receive extra resistance.

  Further, as shown in the drawing, the tension member 52 wraps around the back side of the film body 51 via the folded portion 53 and is bonded to the surface of the film body 51 opposite to the side where the tension member 52 is provided. In the film body 51, it is assumed that the diagonally opposite side of the tensile end 54 of the tension member 52 is also bonded to the same surface side of the film body 51. When the protective film portion 50 is to be peeled off from the upper container body 30 at the time of eating, when the pulling end 54 is pulled, only the tensile member 52 is separated from the film body 51 and the essential film body 51 remains in the upper container body 30 as it is. There is also a risk of doing so. That is, it is a peeling defect of the protective film part 50. As illustrated, since the tension member 52 reaches the back side of the film body 51 via the folded portion 53, the film body 51 can always be peeled from the upper container body 30 starting from the folded portion 53 side. In this peeling method, since it can be gradually peeled from the folded-back portion 53 side, no excessive force is applied. The protective film part 50 can be peeled from the upper container body 30 relatively cleanly.

  The engagement state at each of the normal position and the reverse position of the upper container body 30 will be described using the cross-sectional views of FIG. 2 and FIGS. 2 and 4 show a normal state in which the upper container body 30 is placed at a predetermined position above the lower container body 10, and the upper container body 30 in FIGS. 2 and 4 is in a normal position. In the structure of the container 1, the peripheral edge portion 32 and the hanging wall portion 33 of the upper container body 30 are externally fitted to the opening edge portion 12 and the bent wall portion 13 of the lower container body 10. Therefore, the peripheral edge portion 32 and the hanging wall portion 33 become the engaging portion 38 for the opening edge portion 12 and the bent wall portion 13.

  Since the peripheral edge portion 32 of the upper container body 30 is in contact (surface contact) with the opening edge portion 12 of the lower container body 10, the upper container body 30 is stably placed on the upper portion of the lower container body 10. The And since the outward side of the bending wall part 13 of the lower container body 10 is surrounded by the drooping wall part 33 of the upper container body 30, a fitting is formed between both as shown in the figure. In addition, the hanging wall portion 33 is provided with a plurality of protruding portions 33j that protrude toward the inside of the upper container body 30. When the upper container body 30 is in the normal position, the lower end portion of the bent wall portion 13 is pressed and locked by the protruding portion 33j. From this, a larger engagement force is generated from the hanging wall portion 33 to the bent wall portion 13.

  FIG. 5 is different from FIG. 4 in a state immediately before eating when the upper container body 30 is placed upside down (inverted) at a predetermined position above the lower container body 10, and the upper container body 30 is in the inverted position. . In the structure of the container 1 of the embodiment, the reverse engagement portion 37 of the upper container body 30 abuts on the opening edge portion 12 of the lower container body 10, and the peripheral wall portion 39 immediately below the reverse engagement portion 37 is the inner peripheral wall portion 17. This is a form of engagement that fits at the reverse engagement portion 37 that abuts. As can be grasped from the shape of the container 1 (upper container body 30), the reverse engagement portions 37 are arranged in four places. Therefore, the upper container body 30 in the reverse position is temporarily placed on the upper part of the lower container body 10 at the reverse engagement portion 37. For this reason, a gap is generated between the inner peripheral wall portion 17 and the peripheral wall portion 39 in portions other than the reverse engagement portion 37. As shown in FIG. 9, which will be described later, this gap becomes an escape route for the film body 51 that pulls out the protective film portion 50 again.

  6 to 10 will be used to explain how to handle and use the container 1 of the present invention when containing the food and other items. Incidentally, noodles such as chilled udon, chilled Chinese, chilled noodles, buckwheat noodles, or pasta as sold at convenience stores are exemplified as foods contained in containers. The article C0 accommodated in the lower container body inside 14 of the lower container body 10 is noodles such as udon and is a main ingredient. The other articles C1, C2, and C3 that are housed and held in the housing recess 34 of the upper container body 30 are articles that are topped (added) onto the article C0. Articles C1, C2, and C3 are, for example, boiled egg, broiled egg, green onion, wakame, fried ball, cucumber, tomato, avocado, kimchi, pear, ham, shrimp, shiso, sesame seeds, red ginger, fried chicken, tempura, cheese, olives, It is appropriately selected from various foods such as pickles, bonito and laver.

  FIG. 6 shows a state where the upper container body 30 in the normal position is placed on the upper part of the lower container body 10. The container 1 is in a state of sale or the like, and no operation is added to the upper container body 30. In the drawing, the lower container body interior 14 accommodates the article C0. The second storage recess 34b stores the article C1, the third storage recess 34c stores the article C2, and the fourth storage recess 34d stores the article C3. Since each accommodation recessed part is divided so that it may be obvious, individual articles are not mixed before eating. The upper surface of each housing recess is covered with a protective film part 50 (film body 51) to which heat sealing is applied. The article in each receiving recess is protected from the outside of the container. As described above, the engagement of the upper container body 30 with the lower container body 10 includes the opening edge portion 12 and the bent wall portion 13 of the lower container body 10, the peripheral edge portion 32 and the hanging wall portion 33 of the upper container body 30. The outer fit.

  FIG. 7 shows a state where the upper container body 30 is removed from the upper part of the lower container body 10 in the normal position. As can be seen from the figure, the upper container body 30 itself becomes the lid of the lower container body 10 that houses the article C0. Since the protective film unit 50 covers and protects the articles C1 to C3 accommodated in the upper container body 30, a lid dedicated to the accommodation recess 34 of the upper container body 30 can be omitted. Therefore, the material constituting the container 1 can be reduced.

  FIG. 8 shows a state in which the upper container body 30 that has been lifted is turned over to be in the inverted position. In containers (such as the above-mentioned Patent Document 1) to which the conventional protective film part is not attached, the inner pan for storing the topping article after the outer lid or the inner lid has been removed is inadvertently tilted. Cannot be handled carefully until it is moved to the lower container body. On the other hand, in the embodiment of the present invention, the protective film part 50 is adhered to the upper container body 30. For this reason, even if the upper container body 30 is handled somewhat roughly, the articles C1 to C3 housed in the housing recesses of the upper container body 30 do not immediately fall. That is, handling of the upper container body 30 that accommodates the topping articles C1 to C3 is easy.

  FIG. 9 shows a state where the upper container body 30 is once lifted to the inverted position and placed on the lower container body 10 again. Moreover, the sticking of the protective film unit 50 is starting to be released. The engagement between the upper container body 30 in the inverted position and the inner peripheral wall portion 17 of the lower container body 10 is the same as that described with reference to FIG. For example, in the case of a conventional container (the above-mentioned Patent Document 1, etc.), the middle dish for storing the topping article is lifted and separated from the lower container body, and then is accommodated in the middle dish to the lower container body side. It was necessary to gradually move the articles to the lower container body 10 side with chopsticks, spoons and the like. The work before eating is complicated and time-consuming, and there is a risk of spilling items along the way.

  In order to cope with the above-mentioned problems, the greatest feature of the container 1 of the present invention is that the article in one container (upper container body 30) is replaced with the other container by inverting one container (upper container body 30). It exists in the point which was movable to the (lower container body 10) side. However, the article in one container (upper container body 30) spills off in the middle by simply reversing. Therefore, the articles C1 to C3 can be held in the accommodation recess 34 of the upper container body 30 even when the reversal position is maintained by attaching the peelable protective film 50. Then, the article can fall and move from the upper container body 30 side as the protective film portion 50 is peeled off only at the time of eating.

  The film body 51 is pulled by pulling the tension member 52. And the protective film part 50 begins to peel from the upper container body 30 of an inversion position gradually. In the drawing, the article C3 is falling and moving from the fourth housing recess 34d that becomes the housing recess 34 immediately above the part that has started to peel off first.

  FIG. 10 shows a state after the protective film portion 50 has been completely peeled off. Articles C3, C2, and C1 fall in order from the accommodation recesses 34 (34d, 34c, 34b) of the upper container body 30 located immediately above the protective film portion 50, and the article C0 accommodated in the lower container body interior 14 You can see that it has moved up. As described above, all the articles can be easily moved only through the two steps of reversing the upper container body 30 and peeling the protective film portion 50 (pulling the tension member 52). Accordingly, it is possible to easily and instantly eliminate the complexity of moving the article contained in the conventional container.

  As can be seen from the drawing, since the article moves in substantially the same manner as the arrangement of the accommodation recess 34 of the upper container body 30, the arrangement of the article accommodated in the accommodation recess 34 of the upper container body 30 can be reversed and moved as it is. Therefore, the appearance at the time of eating is not deteriorated and a good atmosphere can be maintained as it is. Moreover, since the protective film 50 can be easily peeled with one hand, it contributes to making the container barrier-free. In addition, it can produce the fun as if drawing a tablecloth. Overall, it can be proposed as a container that can differentiate from other products and appeal to buyers and sellers.

  In addition, the material, size, and shape of the lower container body and the upper container body in the container of the present invention, the number of housing recesses, the strength of sticking of the protective film part, etc. Is selected optimally. For this reason, it is not limited only to the structure and article | item of an Example shown and explained in full detail. For example, it is not limited to the noodles disclosed in the examples and topping articles thereof, and toppings of side dishes such as crackers, omelettes, mapo tofu, etc. can be assumed for lunch boxes, fried rice, nasi goreng, pilaf, or open sandwiches, salads, etc. . Ice cream, hot cakes, cakes, parfaits, sundaes, anmitsu, zenzai, apricot tofu, and other confectionery can be applied to various food packaging such as chestnuts, almonds, chocolates, kojian and grained noodles. Is possible. In fields other than food packaging, the use of blending multiple types of drugs is also promising. For example, a container for dispensing pharmacies such as herbal medicine that contains one basic medicine (herb) in the lower container body and other kinds of medicines in the upper container body and is formulated and finished at the time of use is also considered. . In addition, the use of a storage container in which highly reactive chemical substances are stored separately in the storage state and mixed at the time of use is also considered.
