Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a lid for a food-drinking container, and particularly to a lid for a disposable food-drinking container for storing hot soup or the like.

[Prior Art] In recent years, with the increase in the number of stores selling prepared foods and the increase in the number of vending machines on the streets, it has become increasingly common for people to carry food containers in their hands and eat and drink them while walking.
2. Description of the Related Art It is becoming more and more common to use food and drink containers and make them disposable, such as when holding and eating food in a car. Furthermore, the types of food and drink that can be placed in disposable food and drink containers are becoming more diverse. In other words, even if we only consider drinking liquids that are put into disposable drinking containers, conventionally,
Cold drinking water, such as juice, cola, etc.
Warm drinks, such as tea and hot coffee, have recently expanded to include miso soup, soup, etc.

On the other hand, disposable food and drink containers used for selling drinks on the street are fitted with lids for hygiene reasons and to protect the food and drink by preventing the contents from overflowing.
In this case, if the food is cold drinking water, the lid of the container is generally provided with a notch for inserting a straw, and the straw can be inserted into the notch, and the lid is attached to the container. It is now possible to drink food and drinks through a straw. On the other hand, when the food is hot such as soup, straws are not used, and the lid of the container is removed after each drink.
When eating or drinking is interrupted, it is necessary to attach the lid to the container each time the food is stopped in order to prevent the food from overflowing due to inadvertent external vibrations, which poses problems such as inconvenience. Furthermore, depending on the variety of foods and drinks, drinking a large amount of hot food at one time may cause burns to the inside of the mouth and tongue of the person eating and drinking.

[Problem that the invention aims to solve] This invention was made based on the above-mentioned circumstances, and its purpose is to remove the device once it is attached to a food-drinking container that holds hot food such as soup. To provide a lid for a food and drink container that allows you to easily eat and drink even hot food and drink without having to worry about it.

[Embodiment] An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 shows an eating/drinking container 10 to which a container lid according to the present invention is attached, and a state in which the lid 20 is removed. This food and drink container 10
is made of a material that does not get wet even when hot food such as soup is placed in the container, and has a rigidity that maintains a constant shape against the weight of the food and drink, and has an insulating effect, such as expanded polystyrene. It is made of plastic material such as paper, or a laminated material of paper coated with plastic material. This food/drink container 10 has a cup-like shape in which a circular bottom wall and a cylindrical side wall are integrally formed and has an opening at the top. The side wall of this container 10 is formed so that its diameter gradually increases from the bottom wall toward the opening, and an opening rim 12 with a thicker wall is formed at the open end of this side wall.

The lid 20 to be attached to this container 10 is
It is integrally formed from a sheet made of polypropylene or the like. The lid 20 has a lid 30 that covers the opening of the container 10 to prevent food from flowing out when the lid 20 is attached to a container. A frame portion 40 is formed on the outer periphery of the lid portion 30 and is fitted to the container 10 in a liquid-tight manner. That is, an inner circumferential wall 42 is formed on the outer periphery of the lid portion 30 and is connected to the inner circumferential wall 42 in a substantially perpendicular manner.
An annular rim 44 is formed on the upper part of the annular rim 44, and an annular rim 44 is formed on the outer periphery of the annular rim 44, and an outer peripheral wall 4 is formed on the outer periphery of the annular rim 44.
6 is formed. When the container 10 is attached, these inner peripheral wall 42, annular rim 44, and outer peripheral wall 46 are engaged with the inner peripheral surface of the side wall of the container 10, the rim surface of the opening rim 12 of the container 10, and the outer peripheral surface of the side wall of the container 10, respectively. As a result, the frame portion 40 is fitted into the open end of the container.

The inner circumferential wall 42 and the outer circumferential wall 46 are formed such that their surfaces are inclined from the upper part to the lower part so that the lid body 20 can be stacked on each other before use.
Further, this frame portion 40 has a locking piece 48 arranged at the lower part of the outer peripheral wall 46. The locking piece 48 shown in FIG. 3 is shown with its end folded in to securely attach the lid 20 to the container 10.

This lid body 20 includes a lower part of the inner circumferential wall 42 and a lid part 3.
0, a part of the lid part 30 is cut out to form a notch opening 32.
is formed. This notch 32 has an amount adjusting piece 34 shaped so as to cover this notch 32 by connecting a part of it to the lid 30 in contact with the notch 32.
is formed. As is clear from FIG. 2, the length of the connecting portion 35 between the lid portion 30 and the amount adjusting piece 34 is set depending on the material of the container 10 and the type of food or drink in the container 10. The lid portion 30 and the amount adjusting piece 34 are connected to each other at a position close to the peripheral wall 42 . Lid 30 in contact with this notch 32
is formed so as to surround the notch 32 together with the inner circumferential wall 42 of the frame portion 40 . That is, as is clear from FIG. 3, the lid part 30 has a steep first slope that rises obliquely from the notch opening. The top of this steep slope is in a plane that substantially includes the opening peripheral edge of the container 10, and from this top, a gentle second slope extends toward the inner peripheral wall 42 of the frame 40, It is connected to the inner circumferential wall 42 and closes the opening of the container 10 other than the area corresponding to the notch 32. A re-inflow hole 36 is formed at the bottom of the second inclined portion of the lid portion 30 by cutting out a portion thereof. The shape and size of the re-inflow hole 36 are such that food or drink that has accidentally flowed onto the lid portion 30 can re-flow into the container 10.

Furthermore, this lid body 20 includes a peripheral portion of the inner circumferential wall 42 corresponding to the notch opening 32, and extends outward from the frame portion 40 over approximately 1/3 of the entire circumference of the inner circumferential wall 42. A portion 50 is formed. The shape and size of the mouthpiece 50 extending outward from the frame 40 are appropriately set depending on the shape of the container 10, the viscosity of the food and drink, and the like. As shown in FIG. 3, the mouthpiece 50 has a hollow interior and is connected to the inner peripheral wall 42 and outer peripheral wall 46 of the frame 40 at an angle, and the lid 20 is laminated before use. This mouthpiece part 5
The circumferential width of the upper rim surface of the container 0 is smaller than the circumferential width of the rim surface of the opening rim 12 of the container.

The functions and effects of this embodiment will be described below. When the lid 20 of this embodiment is attached to the container 10, it is less likely to overflow than when the lid is not attached.

In addition, when this lid body 20 is attached to the container 10, the inner circumferential wall 42 of the mouthpiece 50 and the lid part 30
The notch opening 32 is surrounded by the first steep slope of the container 10, so that food and drink will not flow out. However, in the unlikely event that some vibration occurs, the beverage may leak out from the notch opening 32 of the container 10 into the lid. 30, the inclination of the lid 30 that protrudes beyond the notch 32 and the re-inflow hole 36 allows the beverage to flow through the notch 32 and the re-inflow hole 36, as is clear from FIG. The material will flow into the container 10 again.

In addition, there is no need to remove the lid 20 from the container 10 when eating or drinking and to attach the lid 20 to the container 10 when eating or drinking is interrupted. You can eat and drink food continuously regardless of any interruptions. In addition, the notch 32
When eating or drinking from the container, air from the outside flows into the container 10 through the re-inflow hole, and the food or drink can be continuously eaten from the notch 32.

Further, by making the amount adjusting piece 34 slope with respect to the notch 32, the size of the notch 32 can be adjusted, and the amount of beverage flowing out can be adjusted. Moreover, in this case, the lid part 40 and the amount adjustment piece 3
4 is provided close to the inner circumferential wall 42 of the frame portion 40, the amount adjusting piece 34 can be freely tilted using the connecting portion 35 as a fulcrum.
By doing this, the outward protrusion of the amount adjusting piece 34 can be made as small as possible, and the situation where the amount adjusting piece 34 comes into direct contact with the nose of the person eating and drinking can be avoided. This can be prevented. This is particularly advantageous if a large amount of the beverage is to be drained as it cools.

Furthermore, the mouthpiece 50 allows a longer outflow path passing through the inner circumferential wall 42 of the lid than in conventional lids, so especially when eating hot food, the flow rate of the amount adjusting piece 34 can be increased. To easily eat and drink food while adjusting and cooling the food appropriately. Further, the outer peripheral wall 4 of the frame portion 40 of the lid body 20
An opening rim 1 in which the peripheral wall of the container 10 is made thicker by a locking piece 48 formed at the lower part from 6.
The locking piece 48 is fixed to the lower part of the lid 20, and the lid 20 is fixed to the container 10 with difficulty in removal.
The stability of attaching the lid 20 to the container 10 is increased.
