Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lid for a container used for carbonated beverages, and more particularly, to a lid for preventing a carbonated beverage from being evacuated.

[0002]

[Background]

 Leakage of carbonated beverages is caused by the fact that carbon dioxide contained in the beverages is released outside the beverages. If the closed container is full of carbonated beverage, the space inside the container is narrow, and the space is filled with air and a small amount of carbon dioxide gas emitted from the carbonated beverage, and the air pressure is high. By suppressing the emission of carbon dioxide more than the present, it is possible to prevent the carbonated beverage from escaping for a long time. However, when the remaining amount of beverage decreases, the space inside the container becomes larger and the pressure inside the space decreases, so carbon dioxide gas is released until the reduced pressure becomes the pressure that can suppress carbon dioxide gas release. become. In other words, if the carbonated beverage is left behind, even if the lid is tightly closed and sealed, the carbonated gas is released into the space with low atmospheric pressure, so that it is not possible to prevent the carbonated beverage from leaking.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to reliably prevent the carbonated beverage from escaping irrespective of the remaining amount of the carbonated beverage, and to provide a lid capable of solving this problem.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention employs the following technical means. It comprises a lid body 3 which is hermetically attached to a spout 61 of a container 6, a pump 2 for introducing air into the container 6, and a valve 5 which opens only when air enters the container 6. The pump 2 communicates with the inside of the container 6 through a communication hole 4 provided in the lid body 3, and the valve 5 opens and closes the communication hole 4 by the operation of the pump 2. The valve 5 has a structure in which a rubber material is formed in a thin plate shape and one side thereof is fixed to the inside of the lid main body 3 so that the communication hole 4 is always tightly closed by its own elastic force. (Claim 1)

According to the first aspect, when the pump 2 is operated, the pressure of the air causes the valve 5 to bend and deform in a direction away from the communication hole 4 to open the communication hole 4 and allow air to enter the container 6. The pressure inside the container 6 rises. When the operation of the pump 2 is stopped, the valve 5 returns to its original shape by its own elastic force, closes the communication hole 4, prevents the air in the container 6 from leaking, and maintains the air pressure. Further, the pressure of the valve 5 is improved by the air pressure in the container 6 so that the valve 5 is more closely adhered to the communication hole 4, and the effect of preventing air leakage is further enhanced. That is, by raising the pressure in the container 6 and maintaining the raised pressure, the generation of carbon dioxide in the carbonated beverage can be prevented.

[0006]

[Embodiment of the invention]

 In order to efficiently inject air into the container 6, it is important to minimize the leakage of air when the valve 5 returns by making the valve 5 return as quickly as possible. Therefore, in the present invention, in order to speed up the return of the valve 5, at least the elastic force of the turned-up portion 7 of the valve 5 is increased. (Claim 2) According to claim 2, the resilient force acting in the bending state is increased by increasing the elastic force of the turning deformation portion 7, so that the valve 5 that turns up is quickly returned. Therefore, loss due to air leakage can be suppressed when air is introduced, so that air can be efficiently introduced.

As a mode for increasing the elastic force of the turning deformation portion 7, there is a mode in which at least the turning deformation portion 7 of the valve is thickened. (Claim 3) In a third aspect, as shown in FIG. 4, the thickness of the valve 5 is reduced from the fixing surface side to the communication hole 4 side (Claim 4), as shown in FIG. In addition, there is a form in which only the turned-up deformed portion 7 of the valve 5 is thickened (claim 5), and a form in which the entire thickness of the valve 5 is thickened as shown in FIG. . 6 (c), the bulb 5 has a substantially triangular shape in plan view with the fixing surface side being the base 51, as shown in FIG. 6 (c). In both cases, there is a form in which the turned-up deformation portion 7 is curved in the direction along the bottom 51 and the portion that closes the communication hole 4 is flat. (Claim 7)

[0008] The form of the pump 2 is not particularly limited, but is preferably a form that does not hinder the storage and opening and closing when attached to a container. Also, the operation mode is not particularly limited, and examples thereof include an operation mode used for measuring blood pressure, and an operation mode in which a bellows mode is pressed from above. The material is a rubber material if it is used when measuring blood pressure, and a rubber material or a synthetic resin material if it is a bellows type. It is important that the pump 2 and the lid body 3 be integrated so that air leakage does not occur. Basically, there is a method of integral molding for integration, but the lid of the present invention is structurally inconvenient. In addition, there is a difference in material between the pump 2 and the lid body 3 depending on the purpose and method of use, and it is extremely difficult to integrally mold the pump 2 and the lid body 3. Therefore, in the present invention, as shown in FIGS. 1 and 2, the lower peripheral edge of the pump 2 is tightly covered on the upper peripheral edge of the lid body 3 and fixedly attached. (Claim 8) According to claim 8, it is a simple method of covering the pump 2 on the lid body 3, and since the pump 2 is tightly adhered and fixed, it is possible to prevent the occurrence of air leakage. it can. It is preferable that the adhesive is adhered with an adhesive using a rubber-based material. By using this adhesive, the adhesive itself functions as a packing, and is extended to a certain extent, so that it is difficult to be peeled off for a long time. Exhibits the effect of preventing air leakage.

The container 6 of the present invention is a container currently used for carbonated drinks, such as a glass container having a spout with a lid, a polyethylene terephthalate container (called a PET bottle), and an aluminum container. All. Since the spout 61 of these containers 6 is usually closed by a cap of a screw cap type, a crown type, a cork stopper type, etc., in the present invention, the lid main body 3 can correspond to the spout 61 of the container 6. Form. (Claim 9) Specifically, as shown in FIG. 1, by forming the lid main body 3 into a screw cap type, it can correspond to a screw cap type lid container 6. (Claim 10) Further, as shown in FIG. 5, the lid main body 6 is formed by using an elastic material so as to be able to be tightly fitted into the spout 61, so that the cap body and the cork type lid can be used. It can correspond to the container 6. (Claim 11)

【Example】

 Hereinafter, an embodiment will be described with reference to the drawings. FIGS. 1 and 2 show a lid 1 according to the present invention. The lid 1 has a bellows type pump 2 using a rubber material, a screw cap type lid body 3 using a hard synthetic resin material, a communication hole 4 opened at the center of the upper surface of the lid body 3, A valve 5 using a material is provided.

The pump 2 has an air intake port 21 opened at the center of the upper surface. The air intake port 21 is closed with a finger to perform a pushing operation, whereby air is put into the container 6, and the pump 2 is collapsed by releasing the finger. When the air is restored, air is sucked into the pump 2 from the air intake port 21. Since the inner diameter of the lower peripheral edge of the pump 2 is slightly smaller than the outer peripheral diameter of the upper peripheral edge of the lid main body 3, when the pump 2 is put on the upper peripheral edge of the lid main body, it is in close contact with the upper peripheral edge. The parts are adhered to each other with an adhesive using a rubber-shaped material, so that the pump 2 and the lid body 3 are surely integrated.

When the container 6 is described as a PET bottle, the lid body 3 of the present embodiment has the same form as a lid normally used for a PET bottle, and can be adapted to the spout 61 of the container 6. When the container is for a crown-type or cork-type lid, the form of the lid body 3 is tightly attached to the outside of the spout 61 of the container 6 using a rubber material as shown in FIG. It shall be fitted.

As shown in FIG. 2 to FIG. 4, the valve 5 has a communication hole 4 formed in a plate shape having a substantially triangular shape in plan view using a rubber material. By fixing, the communication hole 4 is always in close contact with the inner upper surface of the lid main body 3 and the communication hole 4 is closed, and when air enters, the turning deformation portion 7 is turned and deformed to open the communication hole 4. Further, the valve 5 is inclined so that the thickness of the valve 5 becomes thinner from the fixing surface side toward the communication hole 4 side, thereby increasing the thickness of the turn-up deformation portion 7 of the valve 5 to increase the bending repulsion force. Is increasing. Other forms of the valve 5 include those shown in FIGS. 6A to 6C, and these also have the same effect as the valve 5 shown in FIG.

According to the lid 1 of the present embodiment, air is introduced into the container 6 to raise the air pressure in the container 6 by firmly attaching to the spout 61 of the container 6 and pushing or releasing the pump 2. can do. Therefore, the carbon dioxide gas to be generated from the carbonated beverage in the container 6 is suppressed by the high air pressure and is confined in the carbonated beverage, so that it is possible to prevent the carbonated beverage from escaping.

[0015]

[Effect of the invention]

 As described above, the present invention can reliably prevent the carbonated beverage from escaping by increasing the pressure in the container. In addition, if the pressure in the container increases, the degree of tightness of the valve increases, and the effect of more reliably preventing air leakage increases. Therefore, the taste can be maintained for a long time even if the carbonated beverage is left unreacted. In addition, according to the second to seventh aspects, it is possible to suppress loss due to air leakage when air is introduced, so that air can be efficiently introduced. Therefore, the operation of inflating the air becomes extremely easy, and even a weak child or an elderly person can easily perform the inflating operation. According to the eighth aspect, the pump and the lid main body can be surely, quickly and easily integrated, and the leakage of air can be reliably prevented. Further, according to the ninth to eleventh aspects, it is possible to correspond to the spout of the existing container.
