Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air compression cap, and more particularly to an air compression cap that is attached to the mouth of a drinking water container and can retain the taste of the stored drinking water for a long period of time. The present invention relates to an air-compression type cap that can maintain a fresh aroma and a tingling mouthfeel in almost the original state even after drinking carbonated drinking water to some extent, that is, can preserve the taste of drinking water forever.

[0002]

[Problems to be solved by conventional techniques and devices]

 Soft drinks, such as carbonated drinks, lose their original aroma and tingling sensation after some time has passed (after opening) after removing the cap. This is for the following reason.

That is, normally, the pressure inside a resin bottle or glass bottle containing drinking water is raised to about 3 to 4 atmospheres, but once the cap is opened, the pressure is lowered and dissolved carbonic acid is vaporized. After a certain amount of time has passed in that state, carbonic acid is completely vaporized. As a result, the original aroma and tingling mouthfeel are lost.

Drinking water that has lost its unique taste is often uneconomical because it is often discarded without drinking.

When drinking water is ⅓ or ½ and the cap is closed, dissolved carbonic acid contained in the remaining drinking water remains to some extent, so that the phenomenon of completely eliminating taste and aroma can be prevented.

However, since the dissolved carbonic acid and the like are vaporized and filled as a gas in the space inside the bottle made by discharging (drinking) drinking water, the taste and aroma of the drinking water are significantly lost. Cannot be prevented. Also, as pressure leaks through the cap crevice, the taste and aroma are also erased over time.

Therefore, in order to solve the above problems, a device shown in FIG. 8 has been proposed. This is because the carbon dioxide gas contained in the remaining drinking water is not vaporized by returning the pressure inside the bottle to a state almost similar to the original state after drinking some drinking water. Is based on the scientific evidence that the original taste and aroma are retained.

That is, after inserting an insertion tube (900) having a screw on the outer peripheral surface into a mouse (bottle mouth) of a glass bottle, a bearing (400) and a spring (500) were used on the left and right of the upper part. The main body (100) having the check valve is screwed into the insertion tube (900), or the insertion tube (900) is omitted and directly inserted into the mouse of the bottle.

In this state, when the upper handle (200) is moved up and down to perform pumping, external air flows in through the through hole (300) and enters the inside of the glass bottle through the through hole (600). Is filled.

However, in such a cap, the bearings (400) (700) and the springs (500) (800) are rusted and rusty, and the rusted powder is placed on the pressurizing air and the inside of the glass bottle (1000). There was a sanitary problem to enter.

Furthermore, if the bearings (400) (700) rust, the sealing effect will be reduced, so that in this case the intended purpose can no longer be achieved and for this reason it has to be replaced frequently. It was accompanied by inconvenience. In addition, caps with the above structure tend to be expensive due to the difficulty of manufacturing due to their structure, so cap replacement was uneconomical.

Further, since the insertion tube (900) must be separately provided, it is not economical, and it is quite troublesome to fit or remove the insertion tube (900). The assembly of the main body (100) after fitting was also lacking in convenience.

Furthermore, the conventional cap is limited to use for a glass bottle (1000) in which a recessed groove is formed in a bottle mouth (mouse), and is often used for resin drink containers (for example, so-called PET). It couldn't be used for bottles).

In addition, a scoop-like portion (2 ') extends from the lower end portion of the jaw portion (2).

By screwing the screw part (3) into the screw part on the drinking water container (2000) side, the first pipe body (5) can be automatically fitted into the mouth part (2200).

The first tube body (5), the jaw portion (2), and the chevron-shaped portion (2 ′) form a main body (1).

Reference numeral (24) is a sealing ring made of an elastic body such as rubber. The sealing ring (24) is mounted on the peripheral edge of the opening of the mouth (2200).

The second tubular body (20) is inserted into the hole (4) of the first tubular body (5) through the opening at the upper portion of the first tubular body (5). The second tubular body (20) has a cylindrical shape with an upper part closed. Further, the outer diameter of the second tubular body (20) is smaller than the inner diameter of the first tubular body (5), so that the second tubular body (20) is inserted into the first tubular body (5). In the above, there is a ventilation space (26) between the pipes (5) and (20), and the second pipe (20) is vertically moved in the hole (4) of the first pipe (5). It becomes movable. A soft tubular body (21) made of a soft resin or rubber is coaxially inserted through an opening at the lower end of the second tubular body (20). The soft tubular body (21) is continuous with the attachment portion (21a) inserted into the inner portion of the second tubular body (20) and below it, and is exposed from the second tubular body (20). The large-diameter portion (21b) is further connected to the intermediate-diameter portion (22 ') having an outer diameter substantially the same as the outer diameter of the second tubular body (20), and the lower portion from the intermediate portion (22'). In addition, it is constituted by the lowermost end portion (22) having an outer diameter equal to or slightly larger than the inner diameter of the first tubular body (5). In short, the outer diameter of the lowermost end portion (22) of the soft tubular body (21) is such that the outer peripheral portion of the lowermost end portion (22) is in close contact with the inner peripheral surface of the first tubular body (5). Have

In addition, the soft tubular body (21) is provided with an incision line (23) extending in the circumferential direction in the above-mentioned intermediate portion (22 ′). The incision line (23) is a notch and its length is about half of the entire circumference.

A dome-shaped handle (18) having the upper half of the second tubular body (20) disposed inside extends from the upper portion of the second tubular body (20). The inner diameter of the lower portion of the handle (18) is the same as the outer diameter of the jaw portion (2), and can be fitted into the jaw portion (2). Then, the handle (18) that is pushed down together with the second pipe body (20) is pushed down in the state of being fitted to the outside of the jaw portion (2) from the middle of the pushing down operation of the second pipe body (20). Is configured. On the outer peripheral surface of the lower portion of the handle (18), a plurality of protruding ridges (19) extending in the circumferential direction and arranged in parallel in the vertical direction are provided.

The screw part (3) inside the main body (1) is for screwing with the screw part formed in the mouth part (2200) of the drinking water container (2000), and the sealing ring (24) is connected to the mouth part. If the main body (1) is screwed onto the part (2200) and screwed, the sealing effect is sure.

At this time, the first tubular body (5) is inserted into the drinking water container, and the second tubular body (20) and the soft tubular body (21) of the handle (18) are attached to the main body (1). It is inserted into the hole (4) and the lower part of the handle (18) is lightly inserted and fitted while contacting the outer peripheral surface of the jaw (2) of the main body (1).

The scoop-like portion (2 ′) in the lower portion of the main body (1) covers the protruding blade (2100) of the container (2000) and does not expose it to the outside, which is hygienic and has a good appearance. Has the effect of

When the drinking water (3000) remains half or less of the drinking water container (2000), or more, when the cap having the above-mentioned configuration is assembled as shown and the handle (18) is moved up and down, Pumped to fill the outside air into the drinking water container (2000). This procedure will be described in detail below.

That is, as shown in FIG. 3, when the handle (18) is raised, the soft tubular body (21) rises together with the second tubular body (20), but the lowermost end (22) of the soft tubular body (21). ) Is inserted in close contact with the inner surface of the hole (4) of the first tube (5), so that when the soft tube (21) rises, the hole (4) and the second tube (20) ) The internal space pressure drops temporarily.

Then, the soft tubular body (21) is distorted inward, and the incision line (23) that is thinly incised expands. As a result, outside air flows into the hole (4) and the inside of the second tubular body (20) through the incision line (23).

Next, when the handle (18) is lowered, the pressure inside the hole (4) and the inside of the second tubular body (20) increases, so that the soft tubular body (21) receives the pressure and is pushed outward. As a result, the incision line (23) is in close contact and the crevice is closed.

In this state, when the handle (18) is further lowered as shown in FIG. 4 and is lowered to the lowest position, the compressed air inside the hole (4) and the second pipe body (20) is closed. ) Is pressed to fill the drinking water container (2000) through the hole (8) and the hole (13).

Even without using a spring, the closure (14) is pushed up by the air pressure filled in the drinking water container and surely seals the hole (8) of the ventilation pipe (7). Since the sealing member (14) has a conical portion (15) formed thereon, it ideally adheres to the inclined surface (9) of the ventilation pipe (7). That is, it automatically centers and enhances the sealing effect. The curved portion (16) of the closure (14) is formed so that the closure (14) is well subjected to the rising pressure, and the experimental result is obtained, which is more effective than the flat one.

When the pumping motion is continuously performed, the pressure inside the drinking water container (2000) becomes high, and it becomes impossible to fill the air anymore. At this time, however, it is in a good condition. is there.

In this case, the carbon dioxide gas contained in the remaining drinking water (3000) is not vaporized in the space inside the drinking water container (2000) and stops in the drinking water, so that the drinking water is solid. The taste and aroma are well preserved.

Therefore, after opening, it is possible to maintain the taste and aroma even after a long time has passed, and it is possible to enjoy a fresh flavor and aroma by removing the body (1) and drinking water. come.

Further, the present invention can be constructed entirely of synthetic resin, and can solve the problem that rust may occur. Moreover, since the weight can be reduced, the product price increases.

In addition, since no springs are used, there is no fear of damaging the health, the structure is simple, the unit production cost is low, and the sealing effect is high, so there is almost no risk of pressure leaks. Can be reliably achieved.

As described above, the cap of the present invention forms an incision line in the soft tubular body (21) and has an elaborate structure that allows the outside air to flow in. This is a useful device that can certainly function as a check valve without using.

The drawing of FIG. 7 shows another embodiment of the present invention, in which the jaw-like portion (2 ′) which is expanded like a jaw-like shape of the main body (1) is omitted, and the jaw (25) is shown. And the lower end of the handle (18) contacts.

That is, as shown in FIG. 7, in the main body (1), the conical portion (2 ′) extending from the lower end of the jaw (2) is omitted, and the lower end of the jaw (2) is omitted. It is also possible to provide a jaw (25) extending radially outward.

The caps of the above-described embodiments are characterized by further reducing the production cost, give an externally simple feeling, and are effective in a drinking water container having a small protruding wing (2100).

The conical part (15) of the closure (14) may have a semi-circular spherical shape without apex, and instead of the conical part (15), it is inserted into the hole (8) without any gap. It is also possible to use a rod that can be used, and the incision line (23) can be made longer or slightly shorter than the soft tube (21), and it can be made at several places. It can be formed and the material can be transparent or semi-transparent with a beautiful color. Although such an example will not be described with reference to the drawings, it can be said that matters of such a degree of change belong to the technical scope of the present invention.
