Description

[Detailed description of the invention] [Industrial field of application] This invention incorporates an exothermic reaction container that generates heat due to a chemical reaction inside a container for storing food and drinks, mainly liquids such as sake that require heating. Regarding the reaction initiation pin attached to the exothermic reaction container, the pin is mainly used to cause the quicklime contained in the exothermic reaction container to react with the water flowing out by piercing the water container of the plastic container containing water. , relating to piercing pins.

[Prior Art] Conventional exothermic reaction containers that contain liquids that require warming, such as alcoholic beverages, and are built into the container as needed, are made of quicklime that generates heat when it reacts with water, and plastic that contains water. Contains manufactured containers. Then, poke the attached pin through the pin piercing hole formed in the container to make a hole in the water container containing this water, and by pulling out the pin, the water will drain from the hole and react with the quicklime. I was heating it up.

However, in this container, water vapor sometimes spouted out from the pin piercing opening after the pin was pulled out, and for this reason, it was necessary to further cover the container with an overcap after the pin was pulled out.

Therefore, in the present application, we have continued to study containers in which water comes out and reacts by simply sticking a pin into the water container. There is a concern that the container may be confused with this and the pin may be pulled out, and in this case, water vapor will be ejected as in conventional containers.

[Problems to be Solved by the Invention] An object of the present invention is to provide a pin that prevents the pin from being pulled out after being stabbed, thereby preventing the above-mentioned accidents.

[Means for Solving the Problems] The present invention is a container containing a liquid beverage that requires heating, and an exothermic reaction container that generates heat due to a chemical reaction is built into the container. The pin consists of a needle part with a sharp end and a grip part at the other end, and near the grip part of the needle part there is a stopper to prevent the pin from being pulled out, which can be latched onto the puncture opening of the container into which the pin is pierced. The present invention provides a pin characterized by being provided with a pin.

[Function] Since the present invention has the above-described structure, when the pin is inserted all the way to the base, the lid of the exothermic reaction container and the water container inside the container are destroyed, causing an exothermic reaction.
An object to be heated can be heated. Then, insert the pin all the way to the base of the pin hole in the container.
The stopper of the pin is locked to the pin piercing opening and cannot be removed, and the pin piercing opening is blocked to prevent water vapor from spewing out.

[Example] The present invention will be explained below with reference to the illustrated examples. Fig. 2 is a cross-sectional explanatory diagram of a container using the pin of the present invention, and the pin in this container is as shown in the cross-sectional view of Fig. 1. It has a shape. 11 is the pin body of the present invention, 12 is a film (adhesion), 14 is a plastic ring, 15 is a needle portion of the pin 11, 13 is a sharp tip of the needle portion, 13a is a shaft of the needle portion, and 16 is a grip. 17 is a stopper. The tip portion 13 is
When this pin is inserted, the water can be drained smoothly from the water container 5 without having to pull it out.
It is desirable that it be in the shape of an arrow as shown in the figure. That is, water travels along the shaft 13a from the hole in the water container 5 that is broken by the pin 11,
However, in order to make it possible to form a hole with a larger shape than the shaft 13a, the tip 13 is connected to the shaft 13a.
It is preferable to have a cross-sectional portion larger than a.

An example of a container to which the pin of the present invention is applied is as shown in the cross-sectional explanatory diagram of FIG. The ring 14 is fitted into the paper tube 1 and fused. 3 is a metal exothermic reaction container, 4 is a metal lid having a small hole 41 in the center, and 12 is a film that seals this small hole 41. Further, 5 is a plastic water container, and 6 is an object to be heated, such as Japanese sake. Therefore, hot sake can be made inside this container. 7 is quicklime, and 8 is cardboard for insulation with a cross cut in the center. In addition, 9 is an overcap, and there is a hole 9 in the center as a pin insertion hole.
1 is formed. When this container is turned upside down and the pin 11 is inserted through the small hole 41 in the center of the metal lid 4 at the bottom and the hole 91 in the overcap to destroy the water container 5, water will be drained from the hole made in the water container 5. , reacts with quicklime and generates heat. Since the pin 11 consists of a sharp tip 13, a grip part 16, and a stopper 17, after being stuck in the pin 11, it locks in the hole 91 and cannot be pulled out.Furthermore, since the stopper closes the hole 91 from which water vapor spouts out, the water vapor does not flow out. No more gushing.

[Effects of the Invention] According to the present invention, since the pin has a stopper, it becomes impossible to pull it out after being stabbed, and since the stopper closes the pin piercing opening, it is possible to prevent an accident in which water vapor is spewed out from the piercing opening.

Furthermore, if the cross section of the tip is shaped like an arrow, water can be more effectively discharged from the water container and generate heat even when the tube is stuck in and not pulled out. Further, when the pin is pushed in until the stopper is activated, a fitting sound is heard, which has the effect of confirming that the pin has been inserted correctly.
