[Problems to be solved by the invention]
However, since many teapots give priority to the appearance of design, the heat-retaining effect is hardly taken into consideration in the production thereof, and there is a disadvantage that the drink must be immediately consumed after being put in the teapot. . In addition, this type of teapot uses a glass container in the pot body so that the inside can be easily checked, which makes it very easy to break during use and spills when broken. There is a risk of burns due to fresh drinks, or a risk of injury due to broken glass pieces of the pot body, and the user has to ask for careful handling.
[0005]
An object of the present invention is to provide a highly durable teapot that can keep a drink contained therein for a long period of time.
[0006]
[Means for Solving the Problems]
The invention according to claim 1 of the present invention comprises an outer container that covers the pot body at the upper peripheral position of the glass pot body with an airtight sealing member over the entire circumference thereof. A sealed hollow portion is formed between the main body and the outer container, and the outer container is provided with a check valve that can extract only the air in the hollow portion to the outside . The pot main body and / or the outer container Is provided with a lid whose bottom edge reaches a position near the closing member, and a support member for positioning and buffering the pot body in the outer container is provided below the hollow portion. .
[0007]
Here, the teapot is not limited to drinks extracted from tea leaves, but is a concept that means all containers used when putting warm drinks such as coffee in general. Furthermore, the upper position of the pot body is a concept included in at least all the locations above the water level of the drink placed in the pot body. The closing member is not particularly limited as long as it is formed of a material that does not allow air in the hollow portion to escape to the outside. Further, the material of the outer container is not particularly limited, but may be a material that is relatively difficult to break, such as a hard resin. Further, the outer container is preferably formed of a transparent or translucent material so that the user can see the inside of the teapot. The outer container is preferably formed of a material having impact resistance.
[0008]
When formed in this way, a sealed hollow portion is formed between the pot body and the outer container, so that the heat retaining effect of the drink placed in the teapot is dramatically increased.
[0009]
Further, since the closing member is formed of a material having a buffering performance, for example, even when the teapot is dropped on the floor by the carelessness of the user, it is interposed between the outer container and the pot body. The blocking member that absorbs the shock can protect the pot body made of glass, which is relatively easily damaged.
Here, examples of the material having both airtightness and buffering performance include rubber, urethane, and silicon.
[0010]
Further, even if only the heat retaining action by the hollow portion interposed between the pot body and the outer container, a sufficient heat retaining effect can be obtained, but the lower end edge of the pot body or / and the outer container has a closing member. Since the lid that reaches the position near is provided, a hollow portion is formed by the lid and the outer container so as to wrap the entire pot body, thereby further enhancing the heat retaining effect.
[0011]
Further, since the outer container is provided with a check valve that can extract only the air in the hollow part to the outside, for example, when the teapot is heated in a microwave oven or the like, it exceeds the allowable amount expanded in the hollow part. Excess air escapes from the check valve, and the inside of the hollow portion is always kept at a constant pressure.
[0012]
Here, the check valve is a concept including a valve and a vent hole opened and closed by the valve. The check valve is not limited in its shape and size as long as it has a mechanism that allows only the outflow of air from the hollow portion. Further, the portion where the check valve is provided is specifically provided at the bottom of the outer container, but this is not particularly limited.
[0013]
Here, the hanging position of the lower edge of the lid may be a position slightly separated from the closing member, or may be a position in contact with the closing member as long as it does not hinder the opening and closing of the lid. Good.
[0014]
According to the second aspect of the present invention, the lid is provided with a tea strainer that moves up and down in the pot body by the operation of the handle . The tea strainer accommodates tea leaves and contains components of the tea leaves. It is comprised from the housing provided with the extraction part, and the rod which is connected to the handle and supports the housing so that it can move up and down in the pot body, and the housing is formed so that it can be positioned on the top of the pot body. If the degree of extraction of the drink components contained in the pot body is in a moderate state, the casing is positioned closer to the lid, so that the tea leaf components are placed in the pot more than the current state. It can be adjusted so that it is not extracted into the body.
[0015]
Here, the upper part of the pot body refers to a location above the water level position of the drink placed in the pot body. In addition, the means for positioning the housing to the upper part of the pot body is not particularly limited, but specifically, a huge portion is provided in the proximity of the housing in the bar, while the back surface of the lid Examples are provided in which fitting recesses are provided on the side and each is fitted and removed.
[0016]
In the invention according to claim 3 of the present invention, the casing is composed of an upper collar part provided on a bar and a lower collar part provided on the upper collar part via a connecting means, and the connection The means is provided with a connecting part provided in one part so as to be pivotable and detachable to a connected part provided in the other part, and further provided with a stopper for holding each part in a closed state. So, for example, when replacing the tea leaves in the box, by releasing this stopper and making each part openable, the lower cup-shaped parts open downward with gravity, so that Can be easily replaced, and even if the tea strainer is washed, it is possible to divide the parts individually by first releasing the stopper and then removing the connecting part and the connected part. Take out It can be washed to every corner Te.
[0017]
Here, the connecting part and the connected part that constitute the connecting means include those that make it possible to open and close each part and also make the part attachable and detachable. Specifically, The shaft body provided in one of the parts is held rotatably by the clamping part provided in the other part. Similarly, the stopper that constitutes the connecting means may be a means that keeps each part closed, thereby preventing the tea leaves contained in the box from flowing out into the pot body. Specifically, the part provided with the engaging portion is cited.
[0018]
In the invention according to claim 4 of the present invention, the tea leaf extraction part of the casing is provided with a reinforcing member in a state that does not prevent the extraction of the components, so that it can be a relatively low strength portion in the casing. The strength of the area around the extraction unit is reliably maintained, and the casing is not deformed by the influence of heat from the drink.
[0019]
Here, the form of the reinforcing member and the number of the reinforcing members are not particularly limited as long as the casing retains the strength that can withstand the heat of the drink when the reinforcing member is provided. Specifically, there are four reinforcing pieces crossed over the entire open space that forms the extraction part of each part, and further, the crossing part of each reinforcing piece supported by a bar, While increasing the supporting force of the frame centering on the bar, it suppresses the deformation of each part in the front-rear and left-right directions. Moreover, the state which does not prevent extraction of a component specifically means the state in which the communication location between the inside and the pot body is secured in the housing, and the communication state is not particularly limited.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the teapot of the present invention will be described below.
As shown in FIG. 1, the specific configuration of the teapot of the present embodiment is such that a glass pot body 1 having a bottomed cylindrical shape having a tea spout 8 at the upper end portion overlaps the pot body 1. And the resin outer container 2 fixed through the closure member 3 over the entire circumference of the upper position of the pot body 1. By forming in this way, the teapot is connected to the pot body 1. A hermetically sealed hollow portion S is formed between the outer containers 2.
In addition, about the outer container 2 of the teapot of this embodiment, it forms with the translucent resin so that the drink put in can be easily visually recognized from a user.
