Description

Technical Field

[0001] The present invention relates to being able to re-pressurize a commercially available household carbonated beverage such as a PET bottle to a state sufficient to significantly delay the volatilization of carbon dioxide gas and the like from the contents of the container over time, thereby losing the original refreshing feeling and flavor, and being able to maintain the pressure.

[0002] Further, regarding the pressure maintenance, by being able to use the cap (10) attached to the target container, it is possible to obtain a highly reliable airtight performance and pressure maintenance performance, and it is possible to maintain a desired re-pressurized state for a longer time.

[0003] Also, when storing and preserving it in a refrigerator or the like, it relates to the improvement of its operability, functionality, and hygiene, and the ease of management.

Background Art

[0004] Conventionally, there has been a plug body with a pressurizing function that re-pressurizes a container of carbonated beverage water with a pump, or an elastomer in the shape of a hollow sphere, or an ellipse, or the like, and seals the container with the device itself.

[0005] However, the re-pressurization by these is designed on the premise of being operable only with fingertips by prioritizing compactness. For the average user's muscle strength, the re-pressurization is limited to about 1.5 atmospheres, and even if one has sufficient muscle strength, if one tries to pressurize forcibly, the pressurizing part will be damaged, etc. It was difficult to re-pressurize to about 3.5 atmospheres before opening the plug.

[0006] Since those conventional re-pressurizing and sealing devices also serve as a plug as described above, the plug itself could not be removed from the container when maintaining the pressure.

[0007] Therefore, when storing upright in a door pocket for PET bottles in a household refrigerator, there were problems such as the refrigerator door being difficult to close due to the overall length of the container increased by the plug body. Also, when storing horizontally, there were many reported problems such as the content liquid leaking from the check valve etc. of the plug body, and the airtightness and liquid tightness were lower compared to the cap (10) originally attached to the container.

[0008] Among them, in order to solve the problems related to storage due to the increase in the overall length of the conventional plug body, there were proposals such as putting the plug body itself into the PET bottle container or shortening the overall length of the plug body itself. However, also in those cases, similar to the conventional plug body, since the airtight performance depends on the check valve equipped in the plug body, its performance was inferior to the cap (10) attached to the container.

[0009] Furthermore, all of the above-mentioned conventional plug bodies also functioned as caps that bear the pressure themselves, and during use, they directly touched the container contents to a certain extent. Therefore, when using the plug body, extra consideration for hygiene such as thoroughly cleaning the inside every time was necessary.

[0010] Furthermore, as described above, since the conventional plug bodies cannot be removed from the container body, when there were multiple containers that needed to be repressurized at the same time, it was impossible to perform this with one plug body, and the same number of plug bodies as the number of containers to be repressurized was required.

Summary of the Invention

Problems to be Solved by the Invention

[0012] As described above, the conventional plug body has many problems in terms of functionality, operability, hygiene, etc. However, it is certain that it can be repressurized and maintained at a certain pressure to some extent, and is supported by a certain number of users. However, the repressurization by a device designed to be operated only with fingertips, such as a hollow spherical, elliptical, or similar-shaped elastomer, is limited to about 1.5 atmospheres by the average user's muscle strength, and it was difficult to repressurize to about 3.5 atmospheres before opening the plug.

[0013] In addition, the pressure maintaining function by using a check valve is generally lower than that of the cap (10) attached to the container, and there is a problem that the pressure maintaining period by them is generally short, ranging from only a few hours to at most a few days.

[0014] Furthermore, since the conventional plug body also serves as a cap for pressure maintenance, it comes into direct contact with the contents. Therefore, extra consideration in terms of hygiene, such as thorough cleaning every time it is used, is necessary.

[0015] Furthermore, since it also serves as a cap, when there are a plurality of containers of carbonated beverages to be repressurized at the same time, the same number of such plug bodies are required.

[0016] The present invention has been made in view of the above circumstances, and its object is to enable repressurization with a pump having necessary and sufficient functions to reproduce the internal pressure of the container to the same extent as before opening the plug of carbonated beverages, etc.

[0017] And after repressurization, by enabling sealing with the cap (10) attached to the container, it is possible to reproduce the pressure maintaining period to the same extent as before opening the plug.

[0018] In addition, by enabling pressure retention with the cap (10) attached to the container, it becomes possible to remove the pressure-sealing device from the container after repressurization, and thereby enables storage with a volume as small as that before opening, which is required for storage.

[0019] Furthermore, during storage, the repressurization sealing device is prevented from directly contacting the container contents, realizing a hygienic state equivalent to that of normal storage methods.

[0020] And when there are multiple containers that need to be repressurized simultaneously, it is possible to perform this with a single repressurization sealing device. An object of the present invention is to provide a repressurization sealing device that is thus compact, excellent in repressurization performance and pressure retention performance, hygienic, and also excellent in usability.

Means for Solving the Problems

[0021] The repressurization sealing device according to the present invention has a partition wall or cylinder (25) at the lower end that can collectively seal the periphery (28) of the opening of a container such as a PET bottle for carbonated beverages and the cap (10) attached to the container from the outside air.

[0022] At its lowermost part, it has a packing (7) that is crimped and locked to the flange (14) of the stopper of the cap unopened confirmation ring.

[0023] Also, at its upper end, it can also have a pump (27) via a partition wall (26).

[0024] To explain the usage method of the repressurization sealing device according to the present invention configured as above, the user first loosely screws the cap (10) onto the opening (28) of the container to such an extent that it is not tightly sealed.

[0025] Next, the repressurization sealing device (29) according to the present invention is fitted in the direction of the arrow (30) from above. At this time, it is performed while pushing the hooks a, b (8, 9) in the directions of the arrows (33, 34).

[0026] Press down strongly until the state of Fig. 5 is reached, then release your hands from the hooks a and b (8, 9) to complete the fitting.

[0027] After that, compress the external air with a pump (27) or the like.

[0028] The air compressed by a pump (27) or the like passes from the vents a to d (21 to 24) through the air passages a to d (17 to 20) and heads towards the lower part of the cylinder (1). At this time, since the gap between the cylinder (1) and the flange (14) of the plastic bottle is blocked by the packing (7), there is no leakage to the outside, and there is also no backflow from the vent by the check valve (15). Therefore, it is sent into the container through the gap between the cap (10) of the plastic bottle in the unsealed state and the opening of the plastic bottle container (13).

[0029] The user turns the cylinder (1) within the grace period during which the inside of the container is sufficiently repressurized and temporarily pressurized by the check valve (15), and screws the threaded portion of the cap (10) fitted thereto onto the threaded portion of the plastic bottle container (13) to complete the sealing.

[0030] Remove the entire present invention (29) from the plastic bottle container (13), and after confirming that the cap (10) is sealed again, store it in a refrigerator or the like.

Advantages of the Invention

[0031] After repressurization in the present invention, it is possible to maintain the pressure using only the cap (10) attached to the plastic bottle. As a result, the cylinder (29) of the present invention and the pump or the like used for repressurization can be removed from the container, and the same minimum volume as before opening can be maintained even when storing in a narrow space such as a household refrigerator.

[0032] Furthermore, when repressurizing the container, a pump (27) with a relatively large volume and high efficiency or, as shown in the second embodiment later, any pump can be used.

[0033] As a result, higher recompression performance and a longer pressure holding period can be achieved. During storage, it becomes possible to maintain the refreshing feeling and flavor of the contents for a long time, and waste of the contents can be minimized.

[0034] In addition, the recompression sealing device according to the present invention does not come into direct contact with the contents even during recompression, pressure holding, and further storage. Therefore, hygiene management becomes easier compared to a recompression device that also serves as a conventional pressure holding cap.

[0035] Furthermore, since the recompression sealing device according to the present invention used for recompression can be removed from the container after recompression, it also becomes possible to continuously pressurize a plurality of carbonated beverage containers.
