Description

Liquor Bottle Cap {Liquor Bottle Cap}

The present invention relates to a lid of a bottle of Takju, which is made of a plastic material that is easy to open, and a packing containing a combination of a plastic foam material and a nonwoven fabric therein so as to prevent leakage and deterioration of Takju while fermentation gas is properly leaked during distribution. It's about a table top lid.

As you know, Takju (makgeolli) is a Korean unique grain wine made by mixing glutinous rice, non-glutinous rice, barley, wheat, corn, potato, fermented with yeast and water, and filtering it without leaving the Yakju (Cheongju). It is called sake, rice wine, sake, sake, etc. These takju is white and turbid like hot water, less alcohol content of 6 ~ 7 degrees, sweet, sour, bitter, astringent taste is well suited and features a rich and cool taste.

These liqueurs are commercially mass-produced and distributed in plastic takju bottles.The fermentation proceeds during the distribution process until consumers drink it, especially during high temperature periods such as in summer to produce a large amount of fermented gas. Because of this, Tak-ju will expand.

As the Takju bottle expands, the fermentation gas tries to be discharged through the lid. If the sealing of the lid is not complete, the fermentation gas is discharged in a large amount, and the Takju leaks. If the sealing of the lid is too perfect, the fermentation gas is discharged. This is not done at all because Takju bottles are inflated with excessive pressure, so Takju will overflow when the lid is opened.

Excessive leakage of fermentation gas and Takju not only causes the Takju bottle to slack, but also has a problem in which the unique flavor of Takju is not maintained. There is a problem that the flavor is not maintained.

As a result, Takju can maintain its inherent flavor and preserve it for a long time by properly discharging fermentation gas in its distribution process.

Takju bottle cap is especially important for the release of fermentation gas and leakage of Takju, and conventionally, a non-metallic packing is used between the inner surface of the cap and the bottle cap while applying an aluminum cap screwed to a plastic Takju bottle. It is not suitable for the takju bottle where fermentation gas is generated because it is used as it is suitable for a general plastic lid for drinking water.

In particular, such a conventional aluminum lid, the problem of excessive leakage of takju can be said to be the most serious, which in the case of the aluminum lid by capping (capping) by forming an additional screw is the fastening force or the bottle because the fastening It was confirmed that the sealability is poor, and also because the packing itself is not breathable, causing excessive pressure rise inside the bottle.

In addition, Takju is refrigerated to prevent deterioration. If dew forms on the lid surface of the aluminum material, it is difficult to open it due to slipping of the hand. Since silver is different from plastic bottle, it needs to be changed to plastic for the purpose of giving taste to bottle, giving reliability of product, or to prevent hand injury. Conventional packings are made of aluminum or steel Since it is a structure adapted to the lid, when it is still applied to the plastic lid, there is a problem that the sealing property is low and the ventilation can not be maintained properly.

In addition, by forming a cruciform groove or a propeller-type groove in the aluminum lid and inserting a packing on the inner surface of the lid, the fermentation gas is discharged through the cruciform groove or the propeller-type protrusion, and the tack is not discharged. Due to the complicated structure and large manufacturing error of the lid, it is not possible to keep the emission constant, and in order to solve the non-uniformity caused by the manufacturing error, for example, the structure of the structure becomes more complicated, for example, to form a circular wheel with different steps. It could not escape the basic limitations of aluminum lids.

Therefore, the present invention was devised to solve the above problems, and the lid is made of plastic material so that there is no risk of injuries, and it is formed in a structure that is easy to open without giving a sense of heterogeneity with takju bottles, and the packing is suitable for such plastic lids. The purpose of the fermentation gas is to provide a structure that can be properly discharged and minimize the leakage of Takju to prevent the deterioration of Takju and to provide a long-term storage cap.

Takju bottle cap according to the present invention in order to achieve the above object, a spiral protrusion is formed on the inner surface of the body made of plastic is fastened to the takju bottle bottle, the anti-slip irregularities are formed on the outer periphery of the body, the lower section of the body The cutting band is divided by the blemish line, the lid having an insertion groove extending outward from the inner circumferential surface of the body on the inner upper surface of the body, and at least one surface in contact with the bottle, is waterproofed or maintains overall waterproofness A flexible sealed packing having a vent hole communicating with an inner side of the sealed packing, and a porous air permeable film attached to an opposite side of the surface in contact with the bottle opening of the sealed packing, and the sealed packing with the porous air permeable film attached thereto. Characterized in that inserted into the insertion groove of the lid.

Preferably, the hermetic packing may be made of polyethylene foam so that the opposite surface to which the porous air permeable film is attached is waterproof coated.

Preferably the porous air permeable film uses a nonwoven fabric.

In addition, the insertion groove of the body is inclined to increase in diameter toward the inner upper surface of the body in order to prevent separation of the sealed packing and to maintain a small gap between the outer peripheral surface of the sealed packing.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the accompanying drawings Figure 1 shows a table bottle cap according to the present invention. The basic structure of the plastic lid 10 of the present invention is approximately the same as a typical beverage lid, as shown, a spiral protrusion 22 is formed on the inner surface of the body 20, plastic table bottle (2) bottle (4) It is to be fastened along the spiral portion 6 formed on the outer periphery of the body 20, the anti-slip unevenness 24 is formed, the lower side of the body 20 by the cut line 26 of the circumference The cutting band 28 is divided into the cutting band 28 thereof is connected to the body 20 by the bridge 30, the inner wall of the cutting band 28, the wing 32 is protruded at regular intervals While the outer periphery of the bottle opening 4 is pressed, a projection frame 34 is formed at the lower end of the cutting band 28 to have a basic structure to be caught by the locking jaw 8 of the bottle opening 4.

Therefore, when the lid 10 is rotated, the body 20 is raised, and the close wing 32 of the inner wall of the cutting band 28 is caught by the catching jaw 8 of the bottle cap 4, and the protrusion 34 at the bottom thereof. By being caught by the auxiliary, as the rise of the body 20 is broken line 26 and the bridge 30, the cut band 28 is to be opened to separate from the body 20.

The present invention is particularly in the plastic lid 10 having the basic structure as described above, as shown in Figure 1 and 2, the insertion groove extended outward than the inner peripheral surface of the body 20 on the inner upper surface of the body 20 40 to form a flexible sealed packing 50 which is waterproof or maintains the waterproofness on at least one surface thereof, and maintains the unsealed surface of the sealed packing 50, or waterproofness thereof. The porous air permeable film 60 is attached to one surface of both sides, and the ventilating hole 52 is formed in the center of the sealed packing 50 to communicate with the inside of the bottle opening 4, the porous air permeable film 60 It is made of a structure inserted into the insertion groove 40 of the body 20 to be in close contact with the inner upper surface of the body 20.

Preferably, the hermetic packing 50 is made of porous air permeable polyethylene foam to use a waterproof coating on the opposite side to which the porous air permeable film 60 is to be attached, and the porous air permeable film 60 is made of a nonwoven fabric. In use, the thickness in the state in which the sealed packing 50 and the porous air permeable film 60 is attached to maintain a range of 1.3 ~ 1.7mm.

Also preferably, the insertion groove 40 of the body 20 prevents the detachment of the sealed packing 50 and also maintains a small gap between the outer surface of the sealed packing 50 and the body 20. It is inclined to the diameter toward the inner upper surface of the larger.

Takju bottle cap of the present invention made as described above maintains the blocked state as shown in FIG. When the lid 10 is fastened to the bottle cap 4, the end of the bottle cap 4 is press-tightly adhered to the hermetic packing 50. A vent hole 52 is formed at the center of the hermetic packing 50, and the lid 10 is closed. A porous air permeable film 60 is interposed on the inner upper surface such that the fermentation gas and takju in the takju bottle 2 extends to the porous air permeable film 60. When fermentation of Takju proceeds, the pressure rises inside the Takju bottle (2). In this case, since the sealed packing 50 is compressed by the end of the bottle mouth (4), the Takju is not discharged through them and only fermentation gas is porous. It is discharged through the film 60.

In addition, since the insertion groove 40 is formed to be inclined while extending outward from the inner circumferential surface of the body 20 on the inner upper surface of the lid 10 between the side of the sealed packing 50 and the inner circumferential surface of the insertion groove 40 inserted therein. Since a fine gap is formed in the fermentation gas passed through the porous air permeable film 60 can be smoothly discharged.

If the flexible sealed packing 50 does not have a waterproof function as a whole and is made of porous air-permeable polyethylene foam as described above, and the surface contacting the bottle 4 is coated with water, such as the bottle 4 When the remaining portion except for the contact surface is breathable, even if the sealed packing 50 is compressed by itself very fine air flow path is formed through the fermentation gas can also be discharged through its sealed packing 50.

Furthermore, since the anti-slip unevenness 24 is formed on the outer circumference of the body 20 of the lid 10, and the lid 10 itself is formed of plastic, it is easy to open without slipping even if there is moisture on the surface of the lid 10. .

The table below shows the results of comparative tests of the sealability of the lid according to the prior art and the sealability, breathability and taste alteration state of the lid according to the present invention.

Sealability was evaluated by comparing the amount of lactose to the initial weight after filling the lid with a plastic bottle and sealing the lid and then upside down at room temperature for 4 weeks.

The breathable and taste-changing state was filled with plastic bottle in a bottle of Takju, sealed the lid and stored for 4 weeks at 40 degrees Celsius. The evaluation of breathability was to determine the expansion state of Takju bottles, and the evaluation of the taste alteration state was evaluated by the expert to taste one by one.

Example 1

According to the present invention, a plastic lid, and a sealed packing of a polyethylene foam material having a vent hole in the center thereof were prepared in a form using a nonwoven fabric.

Example 2

The same thing as Example 1 was used, but the thing which did not form the ventilation hole in the center of the sealing packing was prepared.

Comparative Example

Conventionally, inside the aluminum lid, a polyethylene packing without a hole in the center was used.

Table 1 below shows the sealability test results, and Table 2 shows the breathability and taste alteration test results.

Sample number Breathable Taste deterioration Comparative example Example 1 Comparative example Example 1 #One Good Good Not found Not found #2 Good Good Not found Not found # 3 Good Good Not found Not found #4 Good Good Not found Not found # 5 Good Good Not found Not found

As can be seen from the above test results, the sealability of the present invention was found to be very excellent. This is the case of the aluminum lid is capping the cap and the bottle cap by forming an additional screw when capping, but the plastic cap of the present invention is already a complete screw is formed on the inner surface is considered to be the main cause of good fastening state. In addition, <Example 2> in which the vent hole was not formed in the center of the sealed packing showed a poor result compared with the comparative example.

In the case of breathability, both the Example and the comparative example maintained a good state that the degree of turbidity caused by overexpansion or excessive leakage was insignificant, and no taste deterioration was found and was determined to be good.

As a result, by adopting a plastic lid according to the present invention, by applying the airtight packing and the porous air-permeable film that forms the vent holes here, the proper discharge of fermentation gas occurs, less leakage of turbid wine and no taste deterioration.

As described above, according to the lid of the tabletop bottle according to the present invention, the lid is made of a plastic material so that there is no risk of injury even after opening the lid, and it can be easily opened without giving a sense of heterogeneity with the plastic tabletop bottle. By providing a packing of a porous porous air permeable film to be suitable for the plastic lid, fermentation gas can be properly discharged and leakage of turbidity can be minimized. Therefore, according to the present invention, it is preferable to prevent the deterioration of takju compared with the conventional aluminum lid method, and can be stored for a long time.
