Description

Specification

Storage container

[Technical field]

The present invention relates to a storage container for storing confectioneries such as chicken eggs or chocolate, cookies, biscuits and the like:

[Background technology]

Storage containers, for example, containers for storing home-use eggs called table eggs, and so-called egg packs, are used to store eggs at poultry farms, etc. for the purpose of selling them to households at supermarkets. When packing in individual units, there are two types of storage container materials that have been widely used in the past: synthetic resin, such as vinyl chloride, and valve mold: Valve mold products are used in many types of products, and are called molded pulp, and egg cartons are called egg cartons.

However, in such a conventional container, there has been a following problem ₃

(1) When the material is made of synthetic resin such as vinyl chloride, it is easy to manufacture and the cost is low, but it must be collected as tedious sorting waste, which is very troublesome and requires Pollution occurs and pollutes the environment: Also, in some municipalities, the frequency of collecting garbage is low, or in some cases, the municipalities' disposal facilities cannot dispose of them. Post-disposal costs are high, and in some European countries, the cost of post-processing is borne by the manufacturer.

(2) If the material is pulp mold, recycled waste paper can be used as the raw material for recycling after disposal, which is an advantage of waste recycling, which reduces pollution and prevents environmental pollution. For that reason, it is very costly.

(a) Barumourd requires a large amount of water because it is manufactured by papermaking.Furthermore, in order to separate and purify residual sludge in the water at the time of drainage, a water treatment facility of the same amount as papermaking equipment is used. Investment is also required.The primary molded pulp product contains more than 70 cents of water by weight, and this water is Requires a large amount of energy to dry in time:

(b) Furthermore, half-molded products are generally thicker than sheet-shaped paper, and irregularities remain on one side, so they cannot be stored or transported in large quantities, and Poor space efficiency: In addition, since the accuracy is not high, it is difficult to remove when tightly piled up, and it is not easy to take out one by one when packing. Therefore, its suitability for automatic packaging machines is low:

[Disclosure of the Invention]

The present invention has been made in order to solve such problems, and it is possible to greatly reduce the occurrence of pollution at the time of disposal. Also, the purpose is to provide storage containers with improved suitability for automatic packaging. -In order to solve the above problem, the storage container of the present invention comprises a paperboard container main body having an article storage section, and a plurality of cup-shaped paperboard article storage cups. A plurality of force-supply mounting holes are formed in the power-supply hole, and an article storage power-supply portion is fitted and mounted in the force-supply mounting hole.

In particular, the article storage cup section has a role of reinforcement by laminating paperboard along the cutting line and laminating so that the extra paper at the edge formed in the required mold is not discarded. To reduce the required material:

Further, when forming the cup mounting hole in the article storage section, a plurality of tongue pieces are formed without punching out the hole, and the tongue pieces are fitted on the side surfaces of the article storage force tap section. It is intended to improve the strength by laminating '),

As described above, the present invention has the following effects:

(1) Since the storage container is made of paperboard, it can be recycled as a raw material for reusing paperboard after use, and the occurrence of pollution during disposal can be greatly reduced.

(2) Since the material is paperboard, there is no need for a water treatment facility or drying oven, and the paperboard is dewatered by rollers compared to the production period of the paperboard as a raw material. Moisture content is overwhelmingly low, saving a great deal of energy required for drying, making it possible to produce storage containers with extremely low cost (3) If the article is egg, egg article storage power Tsu ^off: Part bottom this a force for housing in a state of floating from; because it can prevent cracking of the eggs:

(4) In the article storage section, since the article storage section is attached to the tongue of the tub mounting hole, the paperboard in the section that holds the eggs has a double / triple structure to improve rigidity. In addition, the eggs can be easily broken and stable storage can be achieved:

(5) Since the article storage power lids protrude individually to the outside of the container, if the article storage power hook is formed with an inclination, the storage container will be opened with the lid open. It is possible to superimpose the pouch and the goods collection part, and the thickness of the paper is thin, so the storage efficiency of the storage container production factory and the storage of empty storage containers in, for example, chicken farms In addition, space efficiency when transporting storage containers from a storage container production plant to a poultry farm can be improved, which can greatly reduce costs:

(6) The storage containers can be easily peeled and removed one by one, so stable supply to the automatic packaging machine is possible and work efficiency is high.

(5) Assembling the storage container

The assembly of the storage container from the development view described above will be described with reference to Figs. 7 to 13.

(a) Goods storage

The article storage section 4 has a straight section 12 a, 12 b, 12 c, 12 d and a curved section 12 e, 12 f, 12 g, 1 at the outer periphery of the article storage section 4. Fold 2h slightly inward at the point of the fold curve h, and as shown in Figure 9, as shown in Figure 9, outside the curve edges 12e, 12f, 12g, and 12h Then, the ends of the adjacent straight edges 12a, 12b, 12c, and 12d are overlapped and fixed using glue (or an adhesive, the same applies hereinafter). Fold 13 downward from the fold curve b and turn all tongues 13 downward, as shown in Figures 7 and 8.

Further, the paperboard is extruded from the inner side to the outer side along the two bending points h formed on the projection support portion 9 to form the triangular pyramid-shaped engaging projections 10:

(b) Lid

The lid part 5 folds the partition part 7 to the article storage part 4 side along the two fold curves n at the center part, and the linear edges 14 a and 14 b on the outer periphery of the article storage part 4. , 14c, 14d, and the curved section 14e, 14f, 14g, 14h, are slightly bent inward at the point of the broken curve i, as shown in Figure 10. As shown on the outside of the curved edges 14 e, 14 f, 14 g, 14 h, the ends of the adjacent straight lines 14 a, 14 b, 14 c, 14 d are superimposed. , And fix with glue: Also, the straight edges 14a, 14c are cut by the cutting line p, the first straight edges 14aa, 14ca and the second straight edges 14ab, 144 When the partition 7 is folded up, for example, the first straight edge portions 14 aa and 14 ca are placed outside, and the second straight edge portions 14 ab and 14 cb are pulled out. Glue inside with weights by these. With these, the lid 5 can be assembled and fixed with the edges 14 and the partition 7 raised.

(c) Article storage section

First, all the side pieces 3 b shown in FIG. 6 are folded up from the folding curve g, and the end portions on both sides in the circumferential direction of the side pieces 3 b are sequentially overlapped with each other, As shown in FIG. 11, the upper end is bent by a curved line s-force ^ to form a horizontal flat edge 15: The article storage tub 3 is in this state, as shown in FIG. The overlapping part of the side piece 3b and the flat part 15 is glued together and fixed in a conical shape. With this, the article collecting part 3 is formed by partially and double-plying the paperboard. Strength is improved:

As shown in FIG. 12 and FIG. 13, the assembled article-fixed cut section 3 is inserted into the cup mounting hole 6 of the article storage section 4 of the container body 2, and the flat edge 15 is The outer periphery of the side piece 3 b is glued to the inner surface of the tongue piece 13, and is fixed to the article storage part 4, while being glued around the lip mounting hole 6 of the article storage part 4. In the article storage wrap portion 3, the circumferential ends of the side pieces 3 b overlap with each other to improve strength, and further, a tongue piece 13 is glued to an outer surface of the side piece 3 b. Because the paperboard is partially doubled or tripled, the strength is greatly improved, and the increased strength supports the egg E, ensuring the retention of the egg E:

(6) Egg storage in the collection container

First, as shown in FIG. 1, the egg E is put into the article storage cup 3 with the lid 5 opened. When the egg E is put into the article storage section 3, the outer surface of the egg E comes into contact with the inner peripheral surface of the article storage cup section 3 whose strength is improved by the tongue piece 13 as shown in FIG. Retained: At this time, the egg E does not come into contact with the bottom 3 a of the article storage force tub part 3, and the bottom 3 a is held in a floating state: Therefore, the storage container 1 containing the egg E Even if the bottom 3a of the article storage cup 3 is hit against something during handling, the space between the bottom 3a and the end of the egg will serve as a buffer, and the impact will break the egg E. Hana Re:

Also, even if the storage container 1 is tilted for some reason in a state where the egg E is placed in the container, the strength of the article storage tub 3 is improved, so that the weight of the egg E is withstand. If it breaks and tilts, it will not, ')

Next, after the eggs E are stored in the article storage tub 3, cover the article storage section 4 with the cover section 5. When the cover section 5 is covered, the straight edge of the article storage section 4 on the side opposite to the lid section is used. The projection support portion 9 provided in the portion 12b is inclined slightly inward from the straight edge portion 12b in which the projection support portion 9 is first bent so that the projection support portion 9 can enter the inside of the lid portion 5. At the point of the fold curve f, bend slightly inward and give a reaction force to return to the outside so that the cover 5 is covered. In this manner, the protrusions are supported as shown in FIG. The projection 9 returns to the outside due to the reaction force, and the projection support section 9 comes into close contact with the inner surface of the lid section 5. When the projection support section 9 comes into close contact with the lid section 5, the engagement projection 10 formed on the projection support section 9 is engaged. The cover 5 is sufficiently engaged with the engaging hole 8 and cannot be disengaged. The partition 7 formed on the 內 side of 5 restricts the movement of the eggs E entering between the rows of eggs E. This prevents cracks caused by collisions between the eggs E between the rows of eggs. it can.

Further, the article storage force tap portion 3 of the storage container 1 is manufactured by gluing all side pieces 3 b to form a conical portion, and the conical portion is formed by the tongue piece 1 of the article storage portion 4. Since the glue is reinforced, the glue is reinforced, and even if the egg E breaks, the contents of the egg E will not leak out of the storage area 3:,

(7) Storage and transportation of storage containers

The storage container 1 can open the article storage section 4 and the lid section 5 horizontally even after the assembly and fixing, and the article storage section 4 and the lid section 5 also block the inner and outer spaces formed by bending. It is possible to overlap the concave and convex parts sequentially because the concave and convex parts are still attached.- Therefore, the vertical dimension required for stacking is the thickness of the paperboard of the storage container 1. The dimensions are only the dimensions, and the thickness of the paperboard is very small.

After the storage container 1 manufactured at the manufacturing plant is assembled and fixed, the concave portion and the convex portion are successively overlapped and stacked and stored, and the stacked state is transported from the manufacturing plant to a poultry farm, etc.- [Second embodiment]

In the first embodiment, when the storage container 1 is manufactured, It is also possible to connect the lid 5 and construct a development view, but it is also possible to separate the two and assemble and fix them, and then glue the two parts together. Since the other is not in the way when it is fixed, it has the effect of making each production easier.

[Third embodiment]

In each of the above embodiments, the article storage cuff 3 is formed in a conical shape, but is not limited to a conical shape, and may be a pyramid.

In the case of a pyramid-shaped surface, the corners are convex, and the straight line contacting the egg E is a concave, so even if the article storage 3 hits something, the convex corner The part often hits, and the part of the concave part does not often hit :, Therefore, the egg E in contact with the concave part is hardly directly impacted, and the egg E can maintain a good state

[Fourth embodiment]

In addition to supporting the goods in the middle of the tub 3, the articles can be stored in such a way that they are supported by the bottom 3a and the sides are used as partitions. For example, this is a case in which products such as round or square chocolate, cookies, or broken biscuits such as biscuits, confectionery, and the like are stacked in the article storage space 3 from the bottom 3a. In this case, in order for the article to move in the article storage power box 3 內, the upper and lower inner diameters of the article storage box 3 need to be the same or almost the same:

Therefore, the article storage section 3 is formed not in a cone or pyramid but in a cylindrical or prismatic shape with almost no inclination: This makes it possible to store confectioneries such as chocolate and cookies in the article storage section 3. Can be stored in:

[Fifth embodiment]

In each of the above embodiments, the lid 5 is provided on the container body 2, but when the lid 5 is made of a material other than a transparent resin material, the inside is visible when the lid 5 is closed. Therefore, it is not possible to confirm the presence or absence of goods and the storage status (for example, whether the egg is broken), and consumers are more likely to be worried.

Therefore, the number of article storage cups 3 corresponding to the number of article storage A number of watermark holes are provided so that they can be seen through the watermark hole without opening the lid even after consolidating the articles.The watermark holes are located beside each egg in the diagonal part of the partition. Provided at the location where:

This allows the consumer to visually check the storage status of the goods stored inside at any time: "" The watermark is also provided through a diagonal notch on the top of the lid but on the partition. Because it is formed in the part, foreign matter is hard to enter inside, and foreign matter is hard to collide with the article, so the article is not damaged.

[Example 2]

In the present invention, it is not always necessary to provide the lid, and after storing the article in the article storage section, a separate lid may be put on the article, or the article may be wrapped with a transparent rub or the like. Les ,:

When the lid is covered, a projection support section and an engagement projection 1 may be provided on both sides of the article storage section, and the lid may be engaged on both sides, or a tape may be fixed on both sides. Reply

[Industrial applicability]

INDUSTRIAL APPLICABILITY The present invention can be applied to a container for collecting confectionery such as eggs, chocolate, cookies, biscuits, etc., thereby greatly reducing the generation of pollution during disposal and at a low cost. It can be used in the field of manufacturing and providing storage containers with high base efficiency and high suitability for automatic packaging:
