Description

{Cap for supplying compressed air}

The present invention relates to an air compression type stopper, and more particularly, to a new stopper capable of compressing air to a container end of a container containing a carbonated beverage and pressing the air into the container.

In addition to ordinary bottled water, various products ranging from juice beverages, carbonated beverages, and ionic beverages to functional beverages have been developed and provided to consumers for a long time.

In the case of carbonated beverages, it is loved by consumers because of the unique taste and refreshing sensation of carbonated carbonated beverages when they drink beverages due to carbonated beverages dissolved in beverages. Especially carbonated beverages are well served with food such as hamburgers and pizzas and are supplied as an important beverage in the food service industry.

Carbonated beverages are mainly produced in disposable cans made of iron or aluminum and large products in PET containers. PET canisters are preferred over PET bottles because they can be used in larger quantities than in canned bottles. Generally, in the case of carbonated beverages, there is a disadvantage that the carbonic acid dissolved in the beverage is evaporated or the pressure in the container is reduced in a state where the cap is once opened, and the refreshing sensation and taste are deteriorated.

In order to overcome such disadvantages, according to Registration Practical Utility Model No. 116509, a structure is designed so that the air can be compressed in the beverage cap, and the compressed air is transferred to the inside of the container by pushing the stopper to increase the pressure of the carbonated beverage. have. Since the pneumatic compression stopper injects air into the carbonated beverage container by pumping while operating the upper end of the upper end, excessive force may be required for the piston action of the stopper depending on the pressure inside the container, Is not large.

On the other hand, according to Laid-Open Publication No. 1998-19500, a liquefied carbon dioxide gas compressed in a PET container which has already been opened and partially eaten to retain the original taste of the carbonated drink is injected into the injection device, A technique has been proposed. However, such a gas injection device merely injects liquefied carbon dioxide gas into the carbonated beverage container, and there is a limit to such an injection action that the carbonic acid is mixed in the beverage or the pressure in the container is maintained to maintain the refreshing feeling.

In the end, the existing technologies allow the carbonic acid to retain the stinging sensation of fresh carbonated beverage after opening the carbonated beverage in the same state as when it was originally purchased, but the compression effect of the actual carbonated beverage is not large and the carbonic acid is properly mixed with the beverage There is a substantial inability to do so.

SUMMARY OF THE INVENTION The present invention has been made in view of the above technical background, and it is an object of the present invention to provide a new carbonated drink stopper which can easily supply air of appropriate pressure to a container containing carbonated beverages.

The present invention relates to a stopper which can be used in a container containing carbonated beverages. The stopper converts the pushing action into rotary motion. The impeller compresses the air by rotating motion. The compressed air To provide a carbonic acid drink that can maintain a constant flavor at all times.

Referring to Figures 1A and 1B, there is shown an exterior view of an air compression stop of the present invention. The air compression stopper 100 is connected to the upper end of the container 150 containing the beverage to seal the beverage inside the container so as to be blocked from the outside, and compressed air is compressed in the container by a simple operation as described later Supply.

The air compression type stopper of the present invention is composed of an upper button 110 and a lower body 120, and mechanical parts for compressing air are mounted inside the button and the body. A spring 112 is inserted between the button and the body to elastically press the button relative to the body.

The body includes a gear portion for compressing air at the top (M region) and a mechanical structure of the compression portion, and a threaded portion can be formed on the inner surface so as to be coupled with the upper end of the beverage container have. Between the upper part and the lower part of the body, a valve part for controlling compressed air to be supplied in only one direction is provided.

In addition, a fine through hole 122 may be additionally provided on the side surface of the body so that external air compressed into the beverage container can be introduced into the body.

2 is a perspective view showing an air compression mechanism mounted inside the plug. The air compression mechanism includes a connecting rod 210 that causes linear motion by a pushing action, a crank arm 220 that converts linear motion into rotational motion, a gear portion 230 that amplifies the amount of change in rotational motion, And a compression unit 240 for compressing air from the motion.

The connecting rod 210 includes a fixed shaft 212 and a connecting bar 214 extending downward perpendicular to the fixed shaft. The fixed shaft is mounted inside the above-mentioned button, and the connection bar is embedded in the inside of the button at the upper part and inside the body at the lower part.

The crank arm 220 is rotatably connected to the lower end of the connecting rod of the connecting rod. The crank arm 220 extends in both directions. The first gear 232 of the gear portion is mounted on the pivot shaft. That is, the crank arm acts as the rotation axis of the first gear.

The gear portion 230 may further include a second gear in addition to the first gear 232. 3 is a perspective view showing the gear portion. As shown in FIG. 3, the first gear 232 and the second gear 234 are coupled to the outer circumferential surface of the first gear, as well as the first gear 232 connected to the rotation shaft of the crank arm. The second gear 234 is mounted on the first shaft 235 corresponding to the rotation shaft, and the second gear rotates in accordance with the rotation of the first gear to cause rotation of the first shaft. A pinion 236 is formed on the central outer circumferential surface of the first shaft or is mounted separately.

As shown in FIG. 3, the diameter of the first gear is made larger than that of the second gear so that the rotation of the first gear and the second gear is larger than the rotation of the first gear, .

The rotation generated in the gear unit is transmitted to the compression unit 240 to instantaneously compress the air introduced from the outside. The compression portion includes an impeller 242 formed in a wing-like structure as shown in FIG. 4A and a spiral gear 243 formed in the center of the impeller. The spiral gear is engaged with the pinion of the above-mentioned gear portion, and the rotation direction of the pinion is changed by 90 degrees so that the impeller is rotated.

4B, a second shaft 245 having a sprocket 246 at its center is inserted into the spiral gear body. The second shaft is fixed to the inner surface of the body to fix the vertical position of the impeller while allowing the impeller to be rotated by the sprocket.

A valve 250 is disposed below the gear portion and the compression portion at a predetermined interval. Figures 5a and 5b show valve appearance and exploded view. The valve largely includes an upper plate 252, a center plate 254 disposed on the lower surface of the upper plate, and a lower plate 256 disposed below the center plate. The center plate and the lower plate are elastically spaced apart by a spring 258. [ The upper plate is provided with an opening 253 through which air can partially pass, and an opening 257 through which air can pass also is provided in the lower plate.

The center plate firstly blocks the air inflow through the top plate while maintaining the state of contact with the top plate by the elastic force of the spring. When the outside air is compressed in the above-described compression unit and pressure is applied to the valve, the elastic force of the spring between the center plate and the lower plate is overcome and the center plate is pushed out of the upper plate. Through this process, the air compressed by the compression unit can be transmitted downward through the valve. On the other hand, the valve is kept in contact with the top plate by the elastic force of the spring, so that the air (inside the beverage container) is prevented from escaping above the valve. The outer circumferential surface of the upper plate and the lower plate is fixed to the inner surface of the body so that the relative positions of the upper plate and the lower plate remain unchanged and the position of the center plate is changed between the upper plate and the lower plate by elastic force and compressed air.

The air compression type stopper of the present invention converts the linear motion into rotational motion through the interaction between the mechanical elements mounted on the upper button and the lower body and causes the compression action by the rotational motion, Closing operation of the valve is controlled to supply compressed air into the beverage container.

Referring to Fig. 6, the compression mechanism of the air compression type cap of the present invention will be described in more detail. When the button (110 in FIG. 1A) of the air compression stopper is pressed in a state of being coupled with the beverage container, the connecting rod mounted therein rotates the crank arm connected downward. That is, it converts a linear motion into a rotational motion. And the first gear mounted on both end shafts of the crank arm rotates in accordance with the rotation of the crank arm.

The rotation of the first gear causes rotation of the second gear interlocked with the first gear. The first gear and the second gear have different gear diameters and number of teeth as described above, so that more rotation than the rotation of the first gear is transmitted to the second gear. For example, when the button is pressed once, the rotation of the crank arm causes the first gear of the gear portion to rotate by one cycle, so that the number of revolutions of the second gear increases to rotate a plurality of times. The rotation of the second gear causes rotation of the first shaft on which the second gear is mounted, thereby rotating the spiral gear of the impeller mechanically interlocked with the pinion of the first shaft, thereby rotating the impeller at a high speed.

The impeller compresses the air in the body rapidly, and the pressure of the compressed air instantaneously opens the lower valve. As a result, the space between the upper plate and the center plate of the valve and the through hole of the lower plate are discharged downward . The air thus discharged is supplied into the beverage container (150 in Fig. 1B) connected to the air compression stopper. If carbonated beverages are contained in the beverage container, the carbonated beverage is well maintained in the beverage. Further, the compressed air supplied into the container through the compression can not escape to the outside, and can be kept in the container only, so that the taste of the beverage can be prevented from deteriorating.

The size of each of the gear portion, the compression portion, the valve, and the like, which implement such a compression mechanism, may be reduced to reduce the overall size of the air compression type plug by machining it into fine parts. On the other hand, the air compression type cap of the present invention can be reused for other beverage containers even after one time use by standardizing the size and size of the engaging portion at the top of the beverage container.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Modified, modified, or improved.
