Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to container-filled bonito flakes in which several grams of bonito flakes are filled into a vertically elongated three-dimensional container, which is then replaced with gas and sealed. It is convenient to use when sprinkling a small amount on food.

(Prior art) The apparent specific gravity of dried fish flakes such as bonito flakes and tuna flakes, or dried sardines such as mackerel, horse mackerel, and sardines, increases in apparent specific gravity and increases the area that comes in contact with the air, which prevents moisture and aroma from dissipating and oxidation phenomena. The drawback is that deterioration in texture, color, taste, and aroma cannot be avoided.

Therefore, in the past, kerifobushi was filled in flat (envelope-like) containers made of synthetic resin, such as a laminated film with good gas barrier properties, together with inert gas, and the opening was sealed. −
(Kerebushi manufactured by the method described in Publication No. 15462)
is widely used.

(Problems with the prior art) However, since this container has an extremely small internal volume, in order to fill it with dried bonito flakes, etc., the opening of the container must be forcibly expanded using a machine, and after filling, a push rod I had to force it in. For this reason, the bonito flakes were destroyed by compression and turned into powder, resulting in a large loss of bonito flakes and poor yield. Also, when pushing the bonito flakes into the container with a push rod or pulling the push rod back, the compressed bonito flakes fly up and adhere to the opening of the container, and when the opening is sealed with heat welding, the bonito flakes get caught. This sometimes resulted in defective products with poor sealing properties.

Furthermore, when inspecting products packaged in small quantities for foreign matter, etc., inspection is difficult because the shavings are compressed and filled, which also has the disadvantage of reducing productivity.

In addition, as mentioned above, containers for small-quantity kerifushi products have a flat, envelope-like shape, and since the container itself does not originally form a regular space, external pressure must be applied after filling it with kerifobushi. Since the pressurizing force is transmitted evenly to all surfaces of the packaging material that are in contact with the volume space, the sealing part cannot avoid the influence.

Therefore, the sealing strength of envelope-shaped container products depends on the sealing area.
The tensile load of cutting into 15mm width is about 3kg. Therefore, in order to use the small quantity of karebushi, it cannot be opened easily with one's fingers and must be cut with scissors or the like. Moreover, since the container is in the form of an envelope, if it is left open on a dining table or countertop, the shavings inside will spill out, or the compressed shavings will become linked together, making it inconvenient to shake out the appropriate amount. It was hot.

In particular, it is difficult to obtain an angle of repose for kerifobushi, and its frictional resistance and repulsive force are relatively large. The volume decreases due to vibration during handling during display, and the volume also decreases over time even when left standing, resulting in an unbalanced container volume, resulting in poor appearance and a significant decrease in product value. descend.

In addition, even if the container has a regular shape with a tapered peripheral wall, if a container that is not vertically elongated (for example, Utility Model Publication No. 55-66972) is used, the volume of dried bonito flakes will decrease less, but due to its shape, the volume of dried bonito flakes will be reduced. It was inconvenient to handle and difficult to shake out, and the productivity was poor.

Therefore, conventional containers for packaging several grams of dried bonito flakes have been three-dimensional containers with a fixed volume, such as cylindrical or prismatic containers, or containers such as those described in Japanese Utility Model Application No. 55-66972. Most of the time, envelope-like containers like those mentioned above were used.

(Objective of the invention) The present invention improves the drawbacks of the conventional examples as described above,
What's more, the quality of the kerifobushi can be maintained for a long period of time, and even if the container is vibrated during transportation or display, the volume of the kerifibushi in the container does not decrease much, and furthermore, it can be shaped like a flat envelope as shown in Figure 1. To provide bonito flakes that are easier to use than those stored in a container A, are difficult to spill out from the opening even when placed on a dining table or cooking counter, and do not take up much space.

(Means for Solving the Problems) The present invention is made of a material with good gas barrier properties and is formed into a vertically elongated conical shape, a vertically elongated truncated conical shape, a vertically elongated pyramidal shape, or a vertically elongated truncated pyramidal shape, and which is made of a material with good gas barrier properties. Several grams of shaved bonito flakes made by cutting fish or dried sardines are filled into a three-dimensional container 1 with an opening 3, and an inert gas is substituted into the container 1. The part 3 is sealed with a lid 6 having good gas barrier properties.

(Example) FIGS. 2 to 5 show examples of the present invention. Second
The container 1 shown in the figure is made of a packaging material with good gas barrier properties, is shaped like a truncated cone, has a tapered peripheral wall 2, and has an open end face with a smaller diameter between both longitudinal end faces to form an opening 3. A flange 4 is formed around the periphery, and a tongue-shaped opening knob 5 is formed in a part of the flange 4.

The container 1 shown in FIG. 3 is formed into the same truncated conical shape as that shown in FIG. 2, and the end face with the larger diameter is opened to form the opening 3, contrary to the case shown in FIG.

What is shown in FIG. 4 is a sheet-like lid 6, which is molded from a material with good gas barrier properties and is adapted to cover the opening 3, flange 4, and opening knob 5 of the container 1.

The lid 6 of the present invention is not limited to a sheet-like one, but may be other than that, for example, one that has a fixed shape so that it can be placed over the outside of the flange 4 from above the opening 3 of the container 1 and tightly attached. But that's fine.

The material of the container 1 in the present invention may be any material as long as it has good gas barrier properties, and therefore includes a synthetic resin alone, a laminate of only a synthetic resin, a laminate of a synthetic resin and paper or aluminum foil, etc. The material of the sheet-like lid may be different.

Container 1 is designed to strengthen its durability against external pressure.
The peripheral wall and bottom surface thereof may be made uneven, and the center portion of the lid 6 may be made uneven in order to provide strength.

Furthermore, the container 1 may be provided with a mouth, a groove, etc. for dispensing.

In the present invention, the above-mentioned container 1 is filled with several grams (for example, about 3 to 5 g) of dried bonito flakes, the inside of this container 1 is placed in a chamber, deaerated, and then filled with inert gas, and then opened. A lid 6 is placed over the portion 3 and the opening 3 is sealed by heat welding or the like.

(Effects of the Invention) (a) Since the container 1 has a conical shape, a truncated cone shape, a pyramid shape, or a truncated pyramid shape, the peripheral wall 2 is tapered. For this reason, the frictional resistance between the inner surface of the peripheral wall 2 and the shavings therein increases, and the shavings inside the container 1 sink downward due to vibration during transportation or the passage of time, making it difficult for the volume to decrease. Therefore, when the lid is opened, the product looks good in appearance, does not lose its commercial value, and can be stored in the same state for a long period of time.

(b) Since the container 1 has a conical shape, a truncated conical shape, a pyramidal shape, or a truncated pyramidal shape and has a constant volume, the kerifushi filled in the container 1 is not directly exposed to external pressure, and therefore the kerifushi is less likely to turn into powder. Therefore, even if the sealing strength for sealing the opening 3 of the container 1 is lowered, the opening 3 will never open by itself. Moreover, if it is set low, it can be opened with a small amount of force, and there is no need to use any other cutlery.

(c) Since the peripheral wall 2 is tapered, when shaking out the bonito flakes from the container 1, the desired amount of bonito flakes can be smoothly taken out by simply tilting the opening 3 and shaking it lightly.

(d) Since the container 1 is vertically long, it is easy to hold even when placed on a table or countertop, and since the opening 3 is formed at either end in the vertical direction, it is easy to shake out.

(e) Since the container 1 is vertically long, the opening 3 is narrow, making it easy to dispense, and is especially convenient for sprinkling a small amount onto food served on a plate.

(F) Since the container 1 is vertically long, it does not take up much space or get in the way even if it is placed on a dining table or cooking counter.

(G) Since the opening 3 has a regular shape, there is no need to open the opening each time when filling with bonito flakes, unlike conventional envelope-shaped containers. In addition, since there is no need to push with a push rod, the filling operation becomes easier, the filling device becomes simpler, and the yield rate also improves because the shaved knots are less likely to break into small pieces or powder.

(h) Since the three-dimensional container 1 with a fixed shape is used, even if the opening 3 is small and vertically long, it is difficult for the bonito flakes to adhere to the periphery of the opening 3 when filling it with bonito flakes, and when the opening 3 is covered with a lid. When the bonito flakes are caught between the periphery and the lid, the airtightness of the lid is insufficient, and oxygen enters from there, preventing the bonito flakes from oxidizing and the flavor from escaping.

(li) Since the container 1 is three-dimensional, when inspecting for foreign substances in the container 1 packed in small quantities, the container 1 can be stably placed on the belt conveyor 7 as shown in FIG. Therefore, the inspection by the foreign object detector 8 becomes easier and more accurate, and the inspection accuracy is greatly improved.

(N) Since the container 1 is a three-dimensional container with a fixed shape, it is stable even when placed on a dining table or cooking counter.

(l) If the lid 6 has a tongue-shaped opening knob 5, it can be opened particularly easily. That is, it is sufficient to open an arbitrary area by peeling off the sheet-like lid 6 and the container 1 along the flange 4 from the opening knob 5, and the contents, shavings, do not spill out to the surrounding area.

(E) Since the container has a fixed shape, it is easy to store even if there is leftovers.
