Description

  The present invention relates to a screwed sealed container comprising a cap containing a substance (A) and a container body containing a substance (B), and the container containing the substance (A) is opened during use. It is related with the container with a storage cap provided with the structure which can be mixed with a substance (B).

Conventionally, transparent plastic bottles have been widely used as many beverage containers such as green tea, coffee, juice, sports drinks, and alcoholic beverages. In this case, green tea and the like are particularly susceptible to alteration, and the flavor and color are impaired over time. For this reason, measures for preventing deterioration such as oxidation prevention measures are taken. However, it is not possible to enjoy the taste just after the adjustment.
Recently, among these beverages, it has been elucidated that green tea is extremely effective from the viewpoint of preventing lifestyle-related diseases. For this reason, the health benefits of green tea have been recognized again and are attracting attention. As is well known, green tea contains a water-soluble component (eg, catechin, vitamin C, etc.) and a fat-soluble component (eg, β-carotene, vitamin E, etc.). For health reasons, it is desirable to consume all of these ingredients.
However, most of the green tea beverages currently on the market are leached green tea leaves with water.
Therefore, it is very unavoidable that the fat-soluble component which is another active ingredient of green tea is not included.
Green tea, especially green tea fine powders such as matcha, are easily altered by water, light, and oxygen, and their flavor and color are impaired over time. For this reason, it is difficult to preserve the mixture of green tea fine powder and water for a long period of time while maintaining the freshness at the time of preparation, and provide it as a beverage.

In order to solve this problem, beverage containers each containing two kinds of substances have been proposed or sold as described below.
For example, recently, a plastic bottle cap made of plastic is provided with an inner cylinder that is integrated with the cap and opened at the lower end, filled with green tea powder, and sealed at the lower end with a pressing lid. ing. The bottle has a parent cap fixed to the mouth portion of the main body, and a child cap integrated with the parent cap attached to the upper drinking mouth portion. On the inner wall side of the bottle, a cylinder for removing the pressing lid integrated with the parent cap is provided so as to contact the outer wall of the inner cylinder of the child cap. When drinking, when turning the child cap in the opening direction, the outer edge of the lid is pushed down at the lower end of the bottle on the inner wall of the bottle, and the green tea powder falls into the bottle together with the lid so that it can be mixed with drinking water Yes.
However, this bottle has a double cap structure, unlike a conventional bottle having an external thread and a cap with an internal thread. A bottle having the same structure as this bottle is disclosed in Japanese Patent Application Laid-Open No. 2004-106888. As described above, the present bottle has a complicated structure, and the production cost is likely to increase due to an increase in the amount of resin for producing the cap portion. Furthermore, the presser lid that has fallen into the bottle appears to be a foreign substance, and there are many problems that people feel uneasy or uncomfortable when drinking.
There exists patent document 2 (Unexamined-Japanese-Patent No. 2004-83022) related to said bottle. The cap portion of this bottle has a double structure as in the above-mentioned Patent Document 1. An inner cylinder 5 is provided for filling the detachable cap main body 1 provided in the bottle main body portion, and a bottom lid that can be opened and closed is provided at the lower end of the cylinder. A cap sub-body 2 provided with an inner cylinder 14 that can be inserted into the inner cylinder 5 is attached to the upper part of the inner cylinder 5 integrally with the cap body 1. When the cap 2 is rotated downward, the lid is opened by the lower end of the inner cylinder 2, and the stored item falls into the bottle. The bottle is not only complicated in structure as in the above-mentioned Patent Document 1, but the lid structure of the inner cylinder 1 has a problem in airtightness.
Patent Document 3 (Japanese Patent Laid-Open No. 2003-12015) (1) is provided with an elliptical partition plate that can be divided by turning the cap around the cap housing. (2) A cap housing that has an openable / closable valve mechanism. (3) A method has been proposed in which the cap housing portion is made into a thin film and a needle-like object is pierced and broken. Of these, the method (3) is particularly difficult to handle.
Patent Document 4 (Japanese Patent Laid-Open No. 2002-249175) includes an easily breakable portion provided on an upper portion of an inner cylinder housing portion integrated with a cap, and a weight attached to the bottom portion of the inner cylinder housing portion. When the cap is rotated in the opening direction, the storage part that is broken at the easily breakable part and attached with a weight is dropped into the bottle body. In this method, since the stored item enters the bottle together with the storage container, there is a problem that the mixed property with the stored item in the bottle is poor depending on the stored item. Moreover, since the broken storage container is in the bottle, there is a sense of incongruity and discomfort. In addition, a diaphragm with a double cone hanging down is installed on the top of the storage unit integrated with the cap. When this diaphragm is pushed down, the bottom of the storage unit is broken by the double cone and the stored item falls into the bottle. Some of them have a complicated opening structure.

JP 2004-106888 (FIGS. 14 to 17) JP-A-2004-83022 (FIGS. 1 and 2) JP 2003-12015 A (FIGS. 1 to 5) JP-A-2002-249175 (FIGS. 1 and 2)

As described above, various methods have been proposed regarding a container that prevents the deterioration of the stored item in the cap portion of the bottle and a method for discharging the stored item. However, it has one of the following problems: complicated structure, high manufacturing cost, poor airtightness, problems with the method of discharging stored items, difficulties in handling, anxiety and discomfort Yes.
The present invention solves these problems, and the container (A) that is easily transformed into the cap part and the substance (B) that is contained in the container main body are integrated, and the structure is simple and the container is stored with high airtightness. It is an object of the present invention to provide a container with a storage cap that prevents deterioration of an object and facilitates discharge and mixing of the stored object.

The present invention relates to a sealed screwed container comprising a female threaded cap 1 containing a removable container 2 containing a substance (A) 3 and a male threaded container body 10 containing a substance (B) 11. The container 2 containing the substance (A) 3 is provided with an easily deformable portion (thin portion) 4 and an easily ruptured portion (notch portion) 5 and is turned downward by turning the cap 1 with the internal thread. In this case, the top of the mouth of the male threaded container body 10 serves as a power point, and the easily deformable part (thin wall part) 4 connected to the skirt 6 of the container 2 serves as a fulcrum. A container with a storage cap having a structure in which the notch portion 5 is broken downward and opened, and the substance (A) 3 falls into the container body 10 with a male screw and can be mixed with the substance (B) 11. It is.
The most characteristic feature of the present invention is the method for opening the container 2, and the opening mechanism uses the “principle principle” as described above.

The container with a storage cap of the present invention has a simple and unique structure. In addition, it is easy to use and has a structure that prevents deterioration of the stored items due to high airtightness, and allows the stored items to be easily discharged and mixed.
In this container with a storage cap, various types of liquids, powders, granules and the like can be stored in each container according to the purpose of use, and these can be mixed at the time of use. That is, the utility value is high as a container for a substance that is easily altered by at least one component, or as a container for a substance that is likely to be altered over time when the substances (A) and (B) are mixed.

The container with a storage cap of the present invention is basically composed of the main structure as described above. However, in the implementation, other structural parts and constituent materials of the container, as well as stored items and methods of use, etc. Is described below.
In the drawings shown below, the dimensions, shapes, materials, geometrical arrangements, and the like of the components are merely conceptual diagrams for explanation, and the present invention is not limited thereby. That is, the size, material, shape, geometric arrangement, etc. of these components can be arbitrarily designed according to the purpose of use.

In FIG. 1, sectional drawing of the container with a storage cap of this invention is shown.
This is a sealed and sealed container comprising a female threaded cap 1 containing a removable container 2 containing a substance (A) 3 and a male threaded container body 10 containing a substance (B) 11.
The cap part is a removable container in which a cap 1 with a female thread provided with a banding stopper 8 and a sealing ring 9 is provided with a skirt 6, an easily deformable part (thin part) 4 and an easily breakable part (notch part) 5. 2 is built in. Here, the easily breakable portion (notch portion) 5 is a notch formed in a cross shape from the center of the top surface and bottom surface of the skirt 6 of the container 2 to the easily deformable portion (thin wall portion) 4 or the end of the skirt 6. . This notching method is merely an example, and is not limited thereto.

FIG. 2 is a cross-sectional view showing a state where the easily breakable portion (notch portion) 5 of the container 2 containing the substance (A) 3 is opened.
Here, when the container 2 containing the substance (A) 3 is displaced downward by turning the female threaded cap 2, the top of the mouth of the male threaded container body 10 becomes the power point, and the container 2 The easily deformable portion (thin wall portion) 4 connected to the skirt 6 is a fulcrum, and the easily breakable portion (notch portion) 5 which is the point of action is displaced downward to open the fracture, so that the substance (A) 3 is maintained. The mechanism falls into the threaded container body 10 and can be mixed with the substance (B) 11.

In this container, in order to maintain high airtightness for a long period of time, the top of the mouth of the container main body 10 with the external thread and the bottom of the skirt 6 in contact with the top of the container 2 and the cap 1 with the internal thread in contact with the top A packing can be inserted between the recesses. The packing material is selected from, for example, materials having rubber elasticity such as silicone rubber, butadiene rubber, isoprene rubber, EPDM rubber, EVA resin, polyurethane rubber, or a material that is more flexible than these containers. In addition, as a method for maintaining airtightness, the material of the cap 1 with the internal thread is made more flexible than the material of the container 2 and the concave portion is formed into an Ω-shaped groove, and the upper outer wall of the container 2 and There is also a method in which the upper inner wall of the female threaded cap 1 that is in contact is screwed together and tightened.
In use, when the container containing the liquid is opened in the container body 10 and then the cap is closed again in a state where there is residual liquid, there is a concern about liquid leakage. In order to prevent this liquid leakage, a packing can be attached to the upper surface of the end of the skirt 6.

In the present invention, the material used for the container 2 is generally a metal material such as plastics, aluminum or an alloy thereof. Examples of the plastic include polyolefins such as polyethylene and polypropylene, polyesters such as PET and PBT, polycarbonate, polyamides, fluororesin, polyvinylidene chloride and a copolymer thereof, polystyrene, high impact polystyrene, AS resin, ABS resin, There are MMA resins and blends thereof. However, it is not limited to these, and may be selected from various materials according to the purpose of use.
As the material of the cap 1 with the internal thread, the above-mentioned plastic or metal such as aluminum is used.
The material of the male threaded container body 10 includes ceramics such as glass in addition to the above-described metals such as plastic and aluminum. In a normal beverage container, polyethylene terephthalate, which is a transparent plastic bottle material whose contents can be observed, is used.

The most important here is the selection and design of the material of the container 2. The material is selected from those used for the cap 2 in consideration of tensile strength, elongation, bending strength, bending elastic modulus, impact strength, hardness, and the like. In the case of plastic, these mechanical properties change depending on the composition, molecular weight, molecular weight distribution, density, and molding conditions of those materials. In particular, the dimensions and shapes of the easily deformable portion (thin wall portion) 4 and the easily breakable portion (notch portion) 5 vary depending on the size of the container 2, the material used, the geometrical arrangement, etc., and therefore cannot be uniquely determined. Here, when a force is applied to the end of the skirt 6 from below, the easily deformable portion (thin wall portion) 4 expands and contracts due to compressive stress and tensile stress, but does not break. The easily breakable portion (notch portion) 5 needs to have a size and shape that can be easily broken by the stress at that time.
Further, in the container in which the substance (A) 3 and the substance (B) 11 are respectively accommodated and integrated, the container 2 can be easily opened in use, but breaks due to an impact during handling such as a normal drop. It is necessary to design so as not to have such strength.
The various components described above can be manufactured by a known molding technique.

In order to prevent deterioration of the contents stored in the container 2 due to light, when plastic is used as the container material, a pigment or inorganic filler fine powder is blended to make it light-blocking. Further, in order to prevent deterioration of the contents stored in the container 2 due to oxygen, the inside of the container can be sealed with the cap 1 after being replaced with an inert gas such as nitrogen.
Note that the container main body 10 can also take measures for preventing deterioration due to light or oxygen, as with the container 2, depending on the contents to be stored and the purpose of use.

  The substance (A) 3 and the substance (B) 11 stored in the container with a storage cap of the present invention are not particularly limited, but usually, different types of liquids, powders and granules are stored. These include, for example, drinking water, black tea liquid, oolong tea liquid, juice, coffee liquid, sports drink, soft drink, milk, alcoholic beverage, edible oil, lotion and the like. Examples of powders and granules include powders such as green tea, coffee, milk, vitamins, various seasonings, pharmaceuticals, chemicals, and the like.

Next, a method of using a container that contains and integrates the substances (A) 3 and (B) 11 will be described.
First, the band stopper 8 attached to the cap 1 with the female screw is removed. Next, when the cap 1 is turned in the closing direction, the easily breakable portion (notch portion) 5 of the container 2 is broken and opened, and the stored item (A) 3 falls. Here, the container body 10 is sufficiently shaken to mix the contents. Then, turn the cap in the opening direction to remove the cap and take out the contents.

It is sectional drawing of the container with a storage cap of this invention. It is sectional drawing which showed the state which the easy-to-break part (notch part) 5 of the container 2 which accommodated the substance (A) 3 opened.
