Description

[Technical Field]

[0001] The present invention relates to a container lid and a filled container suitable for use in storing and transporting UFB (ultra-fine bubble) water. [Background technology]

[0002] Conventionally, a method has been proposed in which the entire polyethylene terephthalate bottle, including the lid, is wrapped in a metal foil laminated film with excellent gas barrier properties and then vacuum-packed to prevent the dissipation of small molecular weight gases and volatile components dissolved in the liquid inside the bottle.

[0003] In contrast, glass containers with lids (glass bottles) have generally been used to store and transport UFB water. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-23363 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with UFB water, there is a risk that air (gas) may get mixed into the glass bottle, causing the dissolved fine bubbles (UFB) in the filled solution to decrease during storage and transportation. For example, the UFB in UFB water decreases during storage by dissolving into the air in the bottle, and decreases during transportation by being destroyed by collisions with the air in the bottle.

[0006] Until now, there have been no dedicated containers for storing or transporting UFB water containing dissolved UFBs, and there has been a long-awaited demand for containers that can prevent gas from entering the container and reduce the risk of UFB loss during storage or transportation.

[0007] The present invention has been made in consideration of the above, and its purpose is to provide a container lid and a filled container that can suppress the intrusion of gas into the container and reduce the risk of the microbubbles dissolved in the filled solution decreasing during storage or transportation. [Means for solving the problem]

[0008] In order to achieve the above object, one aspect of the present invention is a container lid that closes the circular upper opening of a container body, and is characterized by comprising: a circular ceiling surface portion; an outer peripheral surface portion that is provided along the outer peripheral portion of the ceiling surface portion and has a locking portion on the inside that locks onto the opening portion of the container body; and a convex portion that is provided facing downward on the ceiling surface portion and that allows gas within the container body to be discharged to the outside when the container body is closed.

[0009] Another aspect of the present invention is characterized by comprising a container lid comprising: a container body having a circular upper opening; a circular ceiling surface portion provided to correspond to the upper opening of the container body; an outer peripheral surface portion provided along the outer peripheral portion of the ceiling surface portion and having a locking portion on the inside that locks to the opening portion of the container body; and a convex portion provided facing downward on the ceiling surface portion for discharging gas within the container body to the outside when the container is closed. [Effects of the Invention]

[0010] According to the present invention, a container lid and a filling container can be provided that can suppress the intrusion of gas into the container and reduce the risk of the microbubbles dissolved in the filled solution decreasing during storage or transportation.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, a container lid and a filling container according to an embodiment of the present invention will be described with reference to the drawings. Note that in the embodiments, the drawings are intended to show a schematic outline of the invention and may differ from the actual ones.

[0013] First embodiment Figures 1 to 3 show a schematic configuration example of a glass container 1 for UFB (ultra fine bubble) to which a container lid and a filling container according to the first embodiment of the present invention are applied. Figure 1 is a schematic cross-sectional view of the glass container 1 for UFB, Figures 2(a) and (b) show the schematic configuration of the lid 20, and Figure 3 is shown to explain the method of attaching the lid 20 to the container body 10.

[0014] Here, we will explain the case where a UFB glass container 1 is constructed using a general glass bottle, which is suitable for use in storing (accommodating) and transporting UFB water 3, a filling material in which a large amount of UFB is dissolved in a solution.

[0015] The UFB glass container 1 according to this embodiment is a glass bottle with a lid, as shown in FIG. 1, and comprises a cylindrical container body 10 with a bottom, a lid (container lid) 20, and a protrusion (convex portion) 30 provided on the inner ceiling surface of the lid 20.

[0016] The container body 10 is, for example, a colorless, transparent glass bottle, and is composed of a circular bottom 14, a body 16 that is cylindrical and extends along the edge of the bottom 14, and a mouth 18 that has an upper opening 12 that serves as an access port that opens to the top of the body 16.

[0017] The mouth portion 18 has an annular upper opening 12 formed by reducing the diameter of the upper end side of the body portion 16, and is provided with a main body locking portion (thread) 19 on the outer periphery thereof to which the lid body 20 is locked.

[0018] The lid 20 closes (seals) the upper opening 12 of the container body 10, and is composed of a ceiling surface portion 22 whose inner diameter is approximately the same as that of the mouth portion 18, and a cylindrical cap portion 24 provided along the edge of the ceiling surface portion 22. The lid 20 is made of, for example, metal or plastic, and the inside of the cap portion 24 is provided with a lid locking portion (thread) 25 that locks with the body locking portion 19 provided on the outer periphery of the mouth portion 18 of the container body 10 when the container is closed.

[0019] As shown in Figures 2(a) and (b), the protrusion 30 is formed into a conical shape with a predetermined volume using rubber or resin, and the outer diameter of its base (bottom surface) that contacts the inner ceiling surface of the lid body 20 is approximately the same as the diameter of the upper opening 12.

[0020] In other words, when the container is closed, i.e., when the lid 20 is attached to the container body 10, the protrusion 30 enters the internal space of the container body 10 through the upper opening 12 and is immersed in the UFB water 3 filled in the internal space.

[0021] In the UFB glass container 1 configured as described above, the lid 20 is attached to the container body 10 in a state where the internal space of the container body 10 is filled with UFB water 3, as shown in Fig. 3. In particular, it is desirable that the UFB water 3 is filled up to the upper opening 12, but it is sufficient if the empty area (unfilled area) from the upper opening 12 to the top surface of the UFB water 3 is equal to or less than the volume of the protrusion 30.

[0022] As the upper opening 12 of the container body 10 is closed by the lid 20, the protrusion 30 is gradually immersed in the UFB water 3 in the internal space, and the UFB water 3 is drained outside the container body 10 in an amount equal to the volume of the protrusion 30.

[0023] In this way, by causing a portion of the UFB water 3 to overflow through the protrusion 30, even if gas such as air is present near the upper opening 12 of the container body 10, the gas can be pushed out (degassed) to the outside of the container body 10 along with the UFB water 3.

[0024] Therefore, when closed, the internal space of the container body 10 can be filled with only UFB water 3, without any excess gas. This avoids the risk of gas mixing in, which could cause the UFB dissolved in the UFB water 3 to dissolve during storage or be crushed during transportation.

[0025] As described above, the UFB glass container 1 according to the first embodiment can prevent gas from entering the internal space of the container body 10, thereby reducing the risk of the UFB dissolved in the filled UFB water 3 decreasing during storage or transportation.

[0026] That is, a protrusion 30 is provided on the inner ceiling surface of the lid 20, and when the lid 20 is attached to the container body 10, the UFB water 3 is allowed to overflow to the outside of the container body 10 by the volume of the protrusion 30. This makes it possible to push out gas present in the internal space of the container body 10, preventing gas from remaining in the internal space or from being mixed in. Therefore, it is possible to prevent a decrease in the UFB dissolved in the UFB water 3 due to gas mixing in the internal space of the container body 10 during storage or transportation of the UFB water 3.

[0027] In particular, when the container body 10 and the lid body 20 are completely submerged in a tank of UFB water 3, it is possible to easily prevent gas from being mixed in during installation without attaching the lid body 20 to the container body 10.

[0028] Second embodiment Figures 4 to 6 show schematic configuration examples of a UFB glass container 1 to which a container lid and a filling container according to the second embodiment of the present invention are applied, where Figure 4 is a schematic cross-sectional view of the UFB glass container 1, Figures 5(a) and (b) show the schematic configuration of the lid 20, and Figure 6 is shown to explain the method of attaching the lid 20 to the container body 10.

[0029] The UFB glass container 1 of this embodiment is an example in which the protrusion 32 is hemispherical, and other than that it is the same as the first embodiment described above, so detailed explanation will be omitted here.

[0030] That is, in the second embodiment, the protrusion 32 is formed in a hemispherical shape with a predetermined volume, for example, made of rubber material, and the outer diameter of its bottom surface, which contacts the inner ceiling surface of the lid body 20, is approximately the same diameter as the upper opening 12.

[0031] In the case of a UFB glass container 1 having a protrusion 32 of this shape, as in the first embodiment, when the container is closed, it is possible to allow the UFB water 3 filled in the internal space of the container body 10 to overflow.

[0032] Therefore, it is possible to prevent gas from entering the internal space of the container body 10, and to avoid the risk of the UFB dissolved in the UFB water 3 decreasing during storage or transportation of the UFB water 3 due to gas entering the interior space.

[0033] Third embodiment Figure 7 shows a schematic diagram of an example of the configuration of a UFB glass container 1 to which a container lid and a filling container according to the third embodiment of the present invention are applied. More specifically, this is an example in which the cross section of the protrusion 30 is trapezoidal.Other than that, it is the same as in the first embodiment described above, so detailed explanations will be omitted here.

[0034] That is, in the case of a UFB glass container 1 having a protrusion 30 of this shape, as in the case of the first embodiment, when the container is closed, it is possible to allow the UFB water 3 filled in the internal space of the container body 10 to overflow.

[0035] Therefore, it is possible to prevent gas from entering the internal space of the container body 10, and to avoid the risk of the UFB dissolved in the UFB water 3 decreasing during storage or transportation of the UFB water 3 due to gas entering the interior space.

[0036] Fourth embodiment Figure 8 shows a schematic configuration example of a UFB glass container 1 to which a container lid and a filling container according to the fourth embodiment of the present invention are applied. More specifically, this is an example in which the protrusion 30 is cylindrical. Since the rest of the configuration is the same as that of the first embodiment described above, detailed explanations will be omitted here.

[0037] That is, in the case of a UFB glass container 1 having a protrusion 30 of this shape, as in the case of the first embodiment, when the container is closed, it is possible to allow the UFB water 3 filled in the internal space of the container body 10 to overflow.

[0038] Therefore, it is possible to prevent gas from entering the internal space of the container body 10, and to avoid the risk of the UFB dissolved in the UFB water 3 decreasing during storage or transportation of the UFB water 3 due to gas entering the interior space.

[0039] In particular, when the outer diameter of the protruding portion 30 is made substantially the same as that of the upper opening 12 , the protruding portion 30 can also function as a seal plug for the upper opening 12 .

[0040] Fifth embodiment Figure 9 shows a schematic diagram of an example of the configuration of a UFB glass container 1 to which a container lid and a filling container according to the fifth embodiment of the present invention are applied. More specifically, this is an example in which the protrusion 30 is cylindrical. Since the rest of the configuration is the same as that of the first embodiment described above, detailed explanations will be omitted here.

[0041] However, unlike the protrusion 30 shown as the fourth embodiment, the outer diameter of the protrusion 30 is smaller than the upper opening 12 .

[0042] In the case of a UFB glass container 1 having a protrusion 30 of this shape, as in the first embodiment, when the container is closed, it is possible to allow the UFB water 3 filled in the internal space of the container body 10 to overflow.

[0043] Therefore, it is possible to prevent gas from entering the internal space of the container body 10, and to avoid the risk of the UFB dissolved in the UFB water 3 decreasing during storage or transportation of the UFB water 3 due to gas entering the interior space.

[0044] Alternatively, the shape of the protrusions 30, 32 may be, for example, a spherical shape or a prismatic shape, and is of course not particularly limited.

[0045] Furthermore, the container body 10 is not limited to a colorless, transparent glass bottle, but may be a colored glass bottle, and there are no restrictions on its shape or size.

[0046] Furthermore, the object to be stored or transported is not limited to UFB water, but can be applied to the filling of various liquids where the inclusion of gases such as air is undesirable.

[0047] The above describes aspects of the present invention by illustrating an embodiment, but this is only an example, and the scope of the invention described in the claims can be modified in various ways without departing from the gist of the invention. [Explanation of symbols]
