Description

  The present invention relates to a stopper for a beverage container, and particularly relates to a stopper for a flip-up beverage container.

  A conventional beverage container has an opening, through which liquid can be injected into the beverage container or liquid can be poured out from the beverage container. There are various types of beverage containers such as water bottles and heat insulating cups. Taking a water bottle as an example, a stopper is generally attached to the opening of the water bottle so that when the water bottle shakes, the liquid is prevented from leaking to the outside and a dustproof function is obtained.

  However, when a plug is screwed into the opening of the water bottle using a male screw and female screw structure, the plug is loosened and removed each time the water bottle is drunk, and then the plug is screwed into the opening again after drinking. It was necessary and very inconvenient.

  In order to solve the problems of the prior art as described above, the water bottle of Patent Document 1 is similarly screwed into the opening, but the spout protruding at a certain height on the top of the water bottle lid is provided. It differs in that the spout is in communication with the inside of the water bottle. The dustproof sealing lid is connected to the water bottle, reciprocates between the open position and the closed position, and a push button is provided outside the water bottle.

  When the stopper is in the closed position, the dust-proof sealing lid moves onto the water bottle, the push-button prevents the dust-proof sealing lid from coming off, and the spout is always covered with the dust-proof sealing lid. When the plug is in the open position, the dustproof sealing lid is released with the push button, and the dustproof sealing lid is removed from the spout.

  However, since the structure of the push button is complicated, the assembly is complicated and it is inconvenient to disassemble and clean.

  Therefore, the improvement of the conventional plug structure has been demanded.

  Hereinafter, an embodiment of a stopper for a beverage container according to the present invention will be described with reference to the drawings.

(First embodiment)
Please refer to FIG. As shown in FIGS. 1-3, the stopper 10 of the container for drinks concerning 1st Embodiment of this invention is applicable to opening of drink containers, such as a bottle, a heat insulation cup, and a water bottle.

  The plug 10 according to the first embodiment of the present invention includes a bottom lid 20, a protective lid 40 pivotally attached to the bottom lid 20, and reciprocating between an open position and a closed position, and a protective lid 40. And an elastic member 30 that generates energy to return to the original position.

  The above-described bottom lid 20 has a ring portion 21. A top portion 23 is formed on the upper surface of the ring portion 21. An internal space 24 is formed between the ring portion 21 and the top portion 23 and connected to an opening of a drinking container such as a water bottle or a heat insulating cup. An internal thread 22 is formed on the inner surface of the ring portion 21 to be screwed into or loosened from the opening of the drinking container.

  The top 23 of the bottom cover 20 has a nozzle 25 raised at a certain height on one side, and two pivoting ears 29 project from the other side. These two pivoting ears 29 are separated by a fixed distance, and the shaft 12 is inserted in each. An air hole 27 and two position restricting grooves 31 are formed in the top portion 23 of the bottom cover 20. The air hole 27 is formed between the pivotal ear 29 (or the shaft 12) and the nozzle 25, and communicates with the internal space 24 of the bottom lid 20. These two position regulating grooves 31 are located on both sides of the air hole 27, respectively.

  A spout 26 that communicates with the internal space 24 of the bottom lid 20 is formed at the center of the nozzle 25. A convex portion 28 is formed on the outside of the nozzle 25. The convex portion 28 has a substantially hook shape in the first embodiment, but may have a rectangular block shape in other embodiments.

  As shown in FIGS. 1 to 3, the protective lid 40 has a substrate 41. One end of the substrate 41 is bent to form an engagement piece 49, and the other end adjacent to the substrate 41 is formed with bumps 43 and pins 44 protruding. A sleeve 45 is formed at the intersection of the substrate 41 and the engagement piece 49, and a water stop packing 50 is inserted into the sleeve 45. A concave portion 47 and two slits 48 are formed in the engaging piece 49 protruding from the sleeve 45, and the shape of the concave portion 47 is substantially the same as that of the convex portion 28, and these slits 48 are formed on the same side of the engaging piece 49. The recess 47 that is not formed and is provided around the engagement piece 49 has favorable elasticity.

  The protective lid 40 has two ribs 46 connected to both sides of the substrate 41. The rib 46 is lower than the engagement piece 49, and one end thereof is connected to the engagement piece 49 to increase the structural strength of the protective lid 40. A pivot portion 42 is formed at the other end of each rib 46. The pivot portion 42 has an annular shape and is fitted onto the shaft 12 to support the protective lid 40 that reciprocates between an open position and a closed position.

  The elastic member 30 includes two first leg portions 32, two winding portions 34, and two second leg portions 36. Each winding part 34 is connected to one end of the first leg part 32 and the second leg part 36. The other ends of the plurality of second leg portions 36 are connected to the lateral portion 38.

  The winding portion 34 is fitted to the shaft 12. Each first leg portion 32 is inserted into the position restricting groove 31, and the first leg portion 32 comes into contact with the bottom lid 20 when the protective lid 40 swings with respect to the bottom lid 20. In addition, since the second leg portion 36 is stretched outside the bump 43 by the lateral portion 38, the second leg portion 36 is regulated by the bump 43 and is prevented from moving too much. Since the lateral portion 38 is in contact with the substrate 41, the protective lid 40 can obtain a stored energy that returns to the original position.

  Please refer to FIG. 4 and FIG. As shown in FIGS. 4 and 5, the protective lid 40 in the closed position is located on the top 23 of the bottom lid 20, the sleeve 45 is fitted to the outside of the nozzle 25, and the spout 26 is sealed by the water-stop packing 50. Is sealed, and effects such as leakage prevention and dust prevention can be obtained. At this time, the convex portion 28 is engaged with the concave portion 47 of the engaging piece 49 to prevent the protective lid 40 from being removed. An annular space 52 is formed between the top 23 of the bottom cover 20, the protective cover 40, and the nozzle 25 so that the plug 10 can be suspended from a hook or the like, for example.

  When the spout 26 of the nozzle 25 is sealed by the sleeve 45, the pin 44 is inserted into the air hole 27 of the bottom cover 20 and closed. Since the pin 44 has a substantially conical shape, the greater the depth at which the pin 44 is inserted into the air hole 27, the higher the sealing degree. Further, when the lateral portion 38 is pressed by the substrate 41 and approaches the first leg portion 32, the diameter of the winding portion 34 is reduced and the elastic member 30 is deformed.

  Since the engagement piece 49 is designed wider than the nozzle 25, the engagement piece 49 can be easily tilted outward to open, and the engagement relationship between the convex portion 28 and the concave portion 47 can be released, and the engagement relationship is released. When the elastic member 30 is restored by accumulating, the protective lid 40 moves away from the top 23 of the bottom lid 20 and moves to the open position in FIG. 3, and the spout 26 of the nozzle 25 is not sealed by the sleeve 45.

(Second Embodiment)
Please refer to FIG. As shown in FIG. 6, the structure of the beverage container stopper 10 according to the second embodiment of the present invention is substantially the same as that of the first embodiment, but the substrate 41 is engaged with the two pivotal portions 42. The difference is that the number of ribs 46 is reduced to one.

  In the second embodiment, the position of the rib 46 is changed from the side of the substrate 41 to the center, but the structural strength of the protective lid 40 can still be increased as in the first embodiment.

  Furthermore, the protective lid 40 has a closed portion 54 formed at a location where the substrate 41 and the engagement piece 49 intersect. When the protective lid 40 is in the closed position, the closed portion 54 replaced from the sleeve causes the nozzle to be closed. 25 spouts 26 can be sealed, and effects such as leakage prevention and dust prevention can be obtained.

  The preferred embodiments of the present invention have been disclosed as described above so that those skilled in the art can understand them, but these do not limit the present invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the utility model registration claim of the present invention should be broadly interpreted including such changes and modifications.
