Description

Insulation container with double cap with air pocket for moisture permeation prevention {CONTAINER EQUIPPED WITH DOUBLE CAP HAVING DAMPPROOF AIR-POCKET FOR ACCEPTOR}

The present invention relates to an insulated container having a double cap having a moisture-proof air pocket,

More specifically, heterogeneous functional tablets, granules or powders of vitamins, such as vitamins and the like, are coupled to an upper portion of a spout of a body having a main storage unit for storing a liquid first internal body such as a soft drink, carbonated water, water, coffee, yoghurt, and milk. An inner cap having an auxiliary storage for storing the second internal body of the inner cap and a double cap consisting of an out cap for hermetically sealing the spout of the body and the auxiliary storage of the inner cap, the lower, upper, side The present invention relates to an insulating container that protects the second internal body from moisture by preventing moisture permeation through a shield that forms an air pocket in part or all of the parts thereof.

In addition to the liquid first internal bodies such as beverages, water, coffee, yoghurt, milk, and the like, various technologies have been proposed in which a heterogeneous functional tablet such as a separate vitamin, a second internal body of granules or powders is introduced into the cap.

For example, Patent Publication No. 10-2004-0017204 (published February 26, 2004) [the sealing device of the container and the cap used in the device],

This patent is used for the sealing device and the sealing device of the container, which allows the liquid consisting of a plurality of raw materials, such as soft drink water, to be separated in each state of the raw materials to be stored in one container in a state that can be mixed in use. It is about the cap provided with the storage chamber of the raw material to become,

This technology belongs to the technology that is not commercialized due to its lack of reality due to problems in mass production, price competitiveness, and above all watertightness.

In addition, there is a patent registration No. 10-0900728 (registration date May 27, 2009) there is a stopper of the container,

This patent discloses a lower portion of the inner tube of the storage member when the end plate is raised and opened at the lower end of the cylindrical end plate, which opens and closes the opening member and discharges the additive contained in the storage member to the opening of the storage member by discharging the opening member. It is about a container stopper which fusion-bonds the easy-fill film body which touches the outer surface and separates from an end plate, prevents penetration of moisture, and is easy to separate.

The product of this patent has problems due to aesthetic disgust and concern about hygiene, such as staining due to moisture or bottled water penetrating into the gap between the piece and the part even before the first opening.

In addition, when drinking the original contents after storing additional drinking water and drinking, there is an aesthetic or hygiene problem due to the original contents remaining between parts of the inner and outer caps afterwards and secondarily.

Furthermore, Patent Publication No. 10-2004-0077839 (published September 07, 2004) [Method and structure of receiving heterogeneous material in the discharge-operated lid] or Patent Publication No. 10-2005-0090112 (Publication) Dated September 12, 2005) [Structure of discharge device containing different materials]

These two patents disclose the contents through the opening and closing portion of the upper portion, but the contents are configured to be introduced into the inner plug portion having a certain area of the lower portion, and the contents are inserted into the contents through the opening portion of the upper portion. This has an improved advantage.

However, these two patents also belong to technologies that are not commercialized due to problems in mass production, cost competitiveness, and watertightness.

In addition, Korean Patent Publication No. 10-2011-0102134 (published September 16, 2011) [container cap with blade guard]

This patent consists of a lower cap having a storage tube accommodated in a container, and an upper cap screwed onto the lower cap, and the upper cap extends a cutting edge of an opening plate border of a storage tube bottom extended to a bottom of an inner cylinder extending downward to the center of the bottom. It has a cutting blade to cut and a blade guard to protect the cutting blade.When the blade guard is separated, it acts as a blade guard to protect the damage from the blade.When the blade is operated, it presses the bottom of the opening plate to easily cut the cutting groove. About a container stopper with a blade protector

This patent discloses a technique for which the cutting reliability of the opening plate by the blade has not been verified and also corresponds to a technique that has not been commercialized.

After all, the prior art, including the conventional literature is a container, in particular, a bottle-type container containing the liquid first internal body, usually moved out of the refrigerator for drinking due to the characteristics of the product stored in the refrigerator or various temperature difference during distribution Water condensation occurs on the outer wall by forming condensation.In this case, the secondary storage part of the inner cap is also spaced apart from the main storage part containing the first internal body and stays near the spout. Moisture condensation occurs as in the outer wall, and this causes moisture permeation into the secondary storage unit containing the heterogeneous functional tablets, such as vitamins, or the second internal body in the form of granules or powders, thereby circulating the dry second internal body. It causes the internal organs to deteriorate within a much shorter period than the deadline. There is a decisive problem that arises.

The present invention is coupled to the top of the spout of the body having a main storage unit for storing a liquid first internal body such as soft drinks, carbonated water, water, coffee, yoghurt, milk, etc., heterogeneous functional tablets, granules or powders of vitamins, etc. An inner cap having an auxiliary storage unit for storing the second internal body, and a double cap consisting of an out cap for hermetically sealing the spout of the body and the secondary storage portion of the inner cap, in particular, the first air By introducing a structure in which the first shield forming the pocket is coupled to the first coupler, the secondary storage unit arranged close to the outside forms water droplets due to temperature difference between the inside and outside of the container due to various factors, that is, condensation occurs due to condensation. The inner cap barrel forming the secondary storage part to have a kind of thermal insulation or heat retention (or cold) property to protect the second storage body from moisture. Having a double cap having a moisture permeation preventing air pockets and an object thereof is to provide a heat-insulating container.

In addition, the present invention forms a second coupler in the upper portion of the second tower covering the barrel opening of the inner cap barrel and the outer cap for tightly sealing the opening of the body spout which forms the secondary storage, the second air in the second coupler Introducing a second shield to form a pocket to form an air pocket structure to the upper portion of the secondary storage of the barrel to protect the second internal body from condensation moisture double cap with a moisture-permeable air pocket for expanding the moisture permeation prevention effect It is an object to provide an insulating container having.

Furthermore, the present invention is configured so that the inner drum in contact with the outer wall of the barrel of the inner cap serves as a third shield to form a third air pocket on the outer wall of the cap to protect the second internal body of the secondary storage unit from moisture. An object of the present invention is to provide a heat insulation container having a double cap to maximize the effect.

Next, the present invention allows the first shield and the second shield to have the same shape, so that the first coupler of the barrel and the second coupler of the second cap of the outcap, respectively, have the same shape, so that the mass productivity and the cost competitiveness are improved. An object of the present invention is to provide a heat insulating container having a double cap having a moisture-permeable air pocket for improving the performance of an important product.
