Description

  The present invention relates to a beverage extraction device, and more particularly, to a beverage extraction device including an elastic assembly ring.

  In recent years, due to advances in craft technology and improvement in quality of life, in addition to paying attention to whether products are virtue when people purchase new products, their convenience, ease of use, and even greater safety This is taken into consideration. Due to such changes in market trends, companies in various industries can respond to the needs of the majority of customers by constantly focusing on research and development, renewal, and further advanced products. Taking beverage containers that can be found everywhere in everyday life as an example, when tea or coffee is to be drunk, users can drink tea leaves or coffee powders filtered from the leachate using a tea bag or filter. doing. However, after brewing the beverage in this manner, the user must still discard the tea bag or first move the tea bag, filter, etc. to another container. Otherwise, the moisture remaining in the tea bag and filter will wet the surrounding environment, causing inconvenience to the user.

  In view of this, the inventor has once researched and developed a beverage extraction device that is convenient for a user to carry and that can quickly leach tea or coffee. 1 and 2, a storage space 10 is recessed inwardly on the top side of the beverage extraction device 1, and a through hole 13 and a plurality of assembly holes 18 are opened at the bottom thereof. The water stop plate 2 is assembled at the bottom of the beverage extraction device 1, and a plurality of protruding bars 21 are provided on the periphery thereof, and each protruding bar 21 can be inserted into each assembly hole 18. Can be reciprocated up and down, and a column body 23 is also provided at the center of the water stop plate 2, the column body 23 can be inserted into the through hole 13, and a water stop block 25 is incorporated at the top end thereof.

  When the beverage extractor 1 is placed on the table and the water stop tray 2 naturally falls, each protruding bar 21 can come into contact with the lower edge of each assembly hole 18 and at the same time, the water stop block 25. However, the through-hole 13 (the state shown in FIG. 1) can be completely shielded, and the liquid in the accommodation space 10 cannot flow out of the through-hole 13. When the beverage extraction device 1 is placed on the cup, the water stop plate 2 is stretched by the cup, so that each protruding bar 21 comes into contact with the upper edge portion in each assembly hole 18, and at this time, for water stop. The block body 25 can move away from the position where the through hole 13 is shielded, and the liquid in the accommodation space 10 can flow out of the through hole 13. Thus, the user can easily put in from the tea bag or the coffee powder by the beverage extraction device 1, and does not have to worry about the outflow of the liquid remaining in the beverage extraction device 1.

  The beverage extractor 1 can effectively put a tea bag or coffee powder by the user. However, in recent years, the news that the crisis of plasticizer incidents and safety of various foods has caught many media plates and consumed. Consumers are increasingly placing importance on ensuring food safety, and many beverage consumers are concerned that heat resistance is not high when it comes to beverage extraction devices made of plastic or acrylic material . The beverage extractor 1 can be manufactured from glass, but if the beverage extractor 1 is designed in various different styles, not only the cost of the glass processing process is increased, but the yield is also affected. Therefore, the inventor considered whether the beverage extraction device 1 can be designed as a “separate type” structure, that is, for the style design, the main part on which the brewing liquid in the beverage extraction device 1 is placed is made of glass, The base part is also made of a plastic material. In this way, not only can the consumer's concerns be effectively resolved, but also the manufacturing costs can be considered. In addition, a trader can combine a container body of the same style (with or without glass) with a pedestal of a different style and combine it as a beverage extraction device with different aspects and textures.

  However, after the inventor has actually tested the glass container, it is difficult to control the tolerance, so when the beverage extractor is designed as a separate type, the beverage extractor leaks due to the assembly seam. It is easy and completely detracts from the basic effect requirements of the beverage extraction device. Even if the “separate” beverage extractor is closely coupled with increased assembly accuracy, the glass's thermal expansion and cold shrinkage characteristics are remarkable. The part is damaged due to the thermal expansion characteristic. Therefore, it is possible to assemble as a beverage extraction device with a “separate type” structure, and further to ensure the stability and ease of use in assembly, and how to make a new beverage extraction device structure in which the leachate does not leak through the assembled gap. Designing has become an extremely important and urgent task to be solved by the present invention.

JP 2001-112629 A

When the beverage extractor is designed with a “separate” assembly method, if it cannot be assembled correctly, there is a possibility that the leachate may easily leak from the gap, and the inventor has made extensive research based on years of research and development experience. As a result of repeated testing and improvement, the beverage extraction device having the elastic assembly ring of the present invention is finally designed, and the product structure that can be manufactured and assembled more easily and is more effective is further provided to the user. We want you to brew various beverages with peace of mind.
The present invention has been made in view of the above-described problems, and an object of the present invention is to use an elastic assembly ring and seal a gap between a container main body and a pedestal so as to be watertight, thereby providing flexibility in design and storage. An object of the present invention is to provide a beverage extraction device capable of improving the management of water and ensuring water tightness.

  The beverage extraction device according to the present invention includes a container main body, a pedestal, an elastic assembly ring, a water stopper and a water-proof plug. The container body has an upper opening at the top and a lower opening at the bottom, and the upper opening and the lower opening communicate with each other to form a leaching space in the container body. The pedestal has a communication hole extending therethrough, and an annular annular wall is projected upward at a portion corresponding to the communication hole at the top, and a water flow passage is formed between the inner wall surfaces of the annular wall. The water channel corresponds to the communication hole. The elastic assembly ring is fitted into the annular wall by deformation by matching the inner diameter with the outer diameter of the annular wall, and can be biased to the outer wall surface of the annular wall so that the inner wall surface becomes watertight, In the state where the outer diameter matches the lower opening and the outer wall surface is provided with a plurality of contact portions along the circumferential direction, the bottom of the container body is attached to the top of the pedestal. The inner wall surface close to the bottom of the container body can be biased so that the contact portion is watertight.

This point will be described in advance.

  Referring to FIGS. 3 to 5, FIG. 4 is a cross-sectional view of the beverage extraction device 3, and FIG. 5 is a cross-sectional view of the beverage extraction device 3 after hiding the elastic assembly ring 33 and the waterstop 34. A first assembly groove 321 is provided at the top of the pedestal 32, a second assembly groove 322 is provided at the bottom thereof, and a communication hole H1 is formed between the first assembly groove 321 and the second assembly groove 322 through the communication hole. By matching the structure of the first assembly groove 321 with the bottom structure of the container body 31, the first assembly groove 321 can be fitted to the bottom of the container body 31, and the outer wall surface of the first assembly groove 321 is close to the bottom of the container body 31. Affixed to the inner wall surface. An annular wall 323 is formed so as to project upward at a portion corresponding to the communication hole H1 in the first assembly groove 321. A water flow passage 323a is formed between the inner wall surfaces of the annular wall 323, and the water flow passage 323a communicates. Corresponds to hole H1. An assembly space 320 is formed by maintaining a predetermined distance between the outer wall surface of the annular wall 323 and the inner wall surface (or the inner wall surface of the first assembly groove 321) near the bottom of the container body 31.

  The elastic assembly ring 33 is made of an elastic material (for example, silicon), and its structure matches the assembly space 320 (for example, the diameter of the inner wall surface of the elastic assembly ring 33 is substantially smaller than the diameter of the outer wall surface of the annular wall 323. 33), the elastic assembly ring 33 is deformed to deform the assembly space 320 in a state where the bottom of the container main body 31 is positioned in the first assembly groove 321. The inner wall surface is biased against the inner wall surface near the bottom of the container body 31 so as to be watertight, and the inner wall surface is biased against the outer wall surface of the annular wall 323 so as to be watertight.

  The waterstop 34 is movably mounted in the second assembly groove 322, and is provided with a water blocking column 341 and an opening 342 at a portion corresponding to the communication hole H1 thereon, and the diameter of the water blocking column 341 is a communication hole.
