Description

  TECHNICAL FIELD The present invention relates to a beverage container that contains a beverage, and relates to a beverage container plug structure that can drink a beverage in a beverage container simply by opening the plug body of the container body.

  Conventionally, beverage containers such as portable stainless steel bottles that carry beverages such as cold water, hot water, and coffee are known. In the stainless bottle, for example, a container body into which a beverage is placed has a vacuum double structure, and a plug body that closes the opening of the container body is composed of a plurality of members, and a heat insulating space is formed therein to achieve heat insulation.

  An example of a conventional stainless steel bottle is shown in FIG. 9 (the whole container body is the same as that shown in FIG. 1).

  The stainless bottle is composed of a container body 1 and a stopper body 2. The container main body 1 has an inner case 1a and an outer case 1b, the internal space 1c between the inner case 1a and the outer case 1b is evacuated, and a drinking mouth 4 having an opening 3 is formed on the upper portion thereof. As a whole, the container has a vacuum double structure.

  The plug body 2 includes three members, an upper plug 2a, an inner plug 2b, and a plug cover 2c. The upper plug 2a has an upper plug outer peripheral screw 2aa on the outer periphery, and the inner plug 2b has an inner plug on the inner periphery. An inner peripheral screw 2ba is provided, and an inner plug outer peripheral screw 2bb is provided on the outer periphery of the inner plug 2b.

  The upper upper surface of the inner plug 2b and the upper lower surface of the plug cover 2c are welded and integrated, and an annular groove 5 having a narrow lower opening is provided between both members. The upper plug 2a, the integrated inner plug 2b and the plug cover 2c are integrated by screwing the upper plug outer screw 2aa of the upper plug 2a with the inner plug inner screw 2ba of the inner plug 2b. A body 2 is formed.

  At the time of closing, the inner plug outer peripheral screw 2bb of the inner plug 2b is screwed into an inner case inner peripheral screw 1aa provided on the upper inner periphery of the inner case 1a. Then, the drinking mouth 4 is fitted into the annular groove 5 of the plug body 2, and the plug body packing 6 provided on the outer periphery of the lower end of the inner plug 2 b closes the opening 3.

  By the way, in such a plug body 2, the inner plug 2 b and the plug body packing 6 are integrated with the plug body 2, and the plug body packing 6 rotates together with the plug body 2 when the plug body 2 is opened and closed. Then, when the plug body 2 is opened and closed and the plug body packing 6 and the drinking mouth 4 are in contact with each other, an oblique resistance is generated between the plug body packing 6 and the drinking mouth 4, As a result, the plug packing 6 is twisted to generate a so-called squeak between the plug packing 6 and the drinking mouth 4.

  Further, such a plug body 2 tends to accumulate dirt in the annular groove 5, but the annular groove 5 has a narrow width and the inner plug 2b and the plug cover 2c are integrated, so that it is difficult to clean them.

JP-A-10-272068

  The object of the present invention is to disassemble the plug body and further rotate the inner plug so as to eliminate the so-called squeal when the plug body 2 is opened and closed, or to easily wash difficult-to-wash areas such as the annular groove. It is to provide a beverage container.

  In order to achieve the above object, the present invention adopts the following configuration.

In the invention which concerns on Claim 1, it is a drink container which has a container main body and the plug body which opens and closes the opening part of the said container main body, Comprising: The said plug body is an upper plug, an inside plug, a plug cover, and plug body packing. The plug body packing is provided in the inner plug, when the plug body is closed, the plug body packing closes the inside of the container body, and when the plug body is opened, the plug cover rotates, The plug packing and the inner plug move up without rotating.

  In the invention according to claim 1, when the plug body is opened, the plug body packing and the inner plug move up without rotating, so that the plug body packing and the opening are separated from the contact state at the initial stage of plug opening. The so-called squeal that the plug packing is twisted due to frictional force can be eliminated. The same applies when closing the plug.In the case of closing, the plug body packing and the opening rotate together until they come into contact with each other. The stopper is moved down without rotating, so that the so-called squeak generated between the stopper packing and the opening can be eliminated.

In addition , since the upper plug, the inner plug, and the plug cover can be disassembled, cleaning of each component after disassembly can be facilitated. For example, if the upper plug is plated, it is possible to remove the upper plug and avoid washing in a dishwasher that damages the plating.

In addition , since the plug cover can be disassembled into the plug cover main body and the plug ring, the narrow annular groove formed between the plug cover main body and the plug ring can be easily cleaned.

Further , by making the inner plug and the plug cover into a single part, it is possible to more easily clean the inner plug and the plug cover after being disassembled.

The bottom plate 13 is a dish-shaped stainless steel member.

  The lower end of the outer case 12 and the upper end of the bottom plate 13 are welded, and the upper end of the inner case 11 and the upper end of the small-diameter portion 16 of the outer case 12 are welded so that the inner case 11, the outer case 12, and the bottom plate 13 A space 18 is formed, and the internal space 18 is evacuated to form a vacuum double structure having high heat retention performance.

  The plug body 20 has an upper plug 21, a plug cover 30, and an inner plug 50. A partially enlarged sectional view thereof is shown in FIG. 2, an upper perspective view thereof is shown in FIG. 3A, and a lower perspective view thereof. Is shown in FIG. 3B, and the state where each member is removed is shown in FIGS.

  The upper plug 21 further has an upper lid 22 and an inner lid 24, and a state seen from obliquely below is shown in FIG. The upper lid 22 has a flat disk part 22a and a short cylindrical part 22b that hangs downward in the center, and a skirt part that hangs slightly downward in an arc on the outer periphery of the disk part 22a. This is a resin member having 22c.

  The inner lid 24 is a hollow, container-shaped resin member that is open at the top, and has an annular flange portion 24a that protrudes outward at the upper end portion. An inner lid outer peripheral screw 24 b that is screwed into the screw 52 is provided.

  Then, as shown in FIG. 5, the hollow portion of the inner lid 24 is placed on the outer periphery of the tube portion 22 b of the inverted upper lid 22, and the inner bottom surface of the upper lid 22 and the upper surface of the flange portion 24 a of the inner lid 24 are brought into contact with each other. Then, the contact surface is ultrasonically welded, and both members are integrated to form the upper plug 21. Then, the upper surface of the upper lid 22 is plated as necessary. In the case of plating, it is preferable to avoid washing with a dishwasher.

  The stopper cover 30 includes a stopper cover body 31 and a stopper ring 40. The plug cover body 31 is a circular shape in plan view having a skirt portion 33 that hangs downward on the outer periphery of the plug cover main body 31, and is a substantially circular shape in which the upper end of the plug ring 40 is fitted in the upper center. Central opening 34. The central opening 34 is provided with two cavities 35 that are small and outwardly recessed in a U-shape in plan view, and are opposed to each other at a position shifted by 90 degrees from the two dents 35. Two straight portions 36 are provided. Further, a substantially annular projection 37 that slightly protrudes inward is provided at the lower end of the inner periphery of the central opening 34 except for the recess 35.

  The plug ring 40 is a cylindrical resin member that is open at the top and bottom, and is opposed to the outer periphery of the upper end in the radial direction in the form of two U-shaped horizontal flanges 41 protruding outward. Further, two linear portions 41a are provided opposite to the positions shifted from the two flanges 41 by 90 degrees.

  Further, on the outer periphery, there are an upper fitting groove 42 for fitting the inner plug packing 45 from the upper side to the lower side, and a plug ring outer peripheral screw 43 to be screwed into the inner case inner peripheral screw 15 of the inner case 11. The inner circumference is flat.

  The inner plug packing 45 is a ring-shaped silicon member having a low height, and has an annular protrusion 46 projecting outward at the center of the outer periphery (see FIG. 2).

  The inner plug 50 is a bottomed, hollow container-like resin member that is open at the top, and has a lower fitting groove 51 for fitting a plug packing 48 on the outer periphery of the lower end thereof. On the periphery, there is an inner plug inner peripheral screw 52 into which the inner cover outer peripheral screw 24b of the inner cover 24 of the upper plug 21 is screwed.

  The inner plug inner peripheral screw 52 is formed as two upper and lower inclined protrusions arranged facing the left and right to facilitate the formation thereof. Further, by changing the inclination of the last screw of the inner lid outer peripheral screw 24b and / or the inner plug inner peripheral screw 52, it is possible to prevent loosening after screwing. FIG. 8 shows a state where the upper plug 21, the plug cover 30 (the plug cover main body 31 and the plug ring 40) and the inner plug 50 are removed.

  The plug packing 48 is an annular silicon member and is fitted into the lower fitting groove 51 of the inner plug 50. When the stopper 20 is attached to the opening 14 of the container main body 10, the outer peripheral portion abuts against the wall surface of the opening 14 and seals the container main body 10. 7 shows a state where the plug body packing 48 is removed from the inner plug 50, and FIG. 8 (bottom view) shows a state where the plug body packing 48 is attached to the inner plug 50.

  The plug 20 is assembled as follows. Before that, the upper lid 22 and the inner lid 24 are welded to form the upper plug 21, and the inner plug packing 45 is fitted into the upper fitting groove 42 on the upper outer periphery of the plug ring 40, so that the lower outer periphery of the inner plug 50 is formed. The plug packing 48 is fitted into the lower fitting groove 51.

  First, the stopper cover 30 is formed by assembling the stopper cover body 31 and the stopper ring 40. The stopper cover body 31 is placed above the stopper ring 40, the flange 41 of the stopper ring 40 and the recess 35 of the stopper cover body 31, and the straight portion 41 a of the stopper ring 40 and the straight portion 36 of the stopper cover body 31 are aligned. The 40 flanges 41 and the straight portions 41 a are fitted into the recesses 35 and the straight portions 36 of the plug cover main body 31.

  In this state, the stopper cover body 31 is pushed downward. Then, the projection 37 of the central opening 34 of the plug cover main body 31 gets over the annular projection 46 of the inner plug packing 45 and fits therebelow. As a result, the plug cover main body 31 and the plug ring 40 are assembled so as to be non-rotatable and sealed.

  The pressing force at this time can be performed with a small force. Therefore, the disassembly / assembly of the plug cover main body 31 and the plug ring 40 can be easily performed. As described above, the disassembly / assembly of the plug cover main body 31 and the plug ring 40 is performed not by screws but simply by fitting or separating in the vertical direction.

  The plug cover body 31 and the plug ring 40 may be formed as an integral part. In that case, cleaning of the annular groove 55 formed by the plug cover main body 31 and the plug ring 40 becomes slightly difficult.

  Next, the integrated plug cover body 31 and the plug ring 40 are placed above the inner plug 50, and the inner plug 50 is inserted into the plug ring 40. Since the inner periphery of the stopper ring 40 and the outer periphery of the inner stopper 50 are flat and the inner periphery of the stopper ring 40 is slightly larger than the outer periphery of the inner stopper 50, the insertion is easy. It is freely rotatable within 40.

  After the insertion, the upper end portion of the inner plug 50 protrudes slightly above the upper end portions of the plug cover main body 31 and the plug ring 40, and the upper surface of the plug body packing 48 abuts against the lower end portion of the plug ring 40 in a watertight manner. The assembled state is shown in FIG.

  Next, as shown in FIG. 4, the upper plug 21 is placed above the assembled plug cover 30 (plug cover main body 31 and plug ring 40) and the inner plug 50, and the inner lid outer periphery of the inner lid 24 of the upper plug 21 is placed. The screw 24b is screwed and coupled to the inner plug inner peripheral screw 52 of the inner plug 50.

  After the coupling, the lower end portion of the skirt portion 22c of the upper lid 22 is opposed to the upper surface of the outer periphery of the plug cover body 31 with a slight gap, and the lower surface of the flange portion 24a of the inner lid 24 is close to the upper end portion of the inner plug 50. The upper surface of the plug body packing 48 closely contacts the lower end of the plug ring 40.

  As a result, the upper plug 21 and the inner plug 50 are strongly united and unitized (hereinafter referred to as a unit object) and move together, and the plug cover 30 is rotatable with respect to the unit object. That is, the stopper cover 30 and the unit object are relatively rotatable.

  The upper plug 21, the plug cover 30, and the inner plug 50 can be coupled simultaneously by the above screwing. The combined state is shown in FIG. That is, the four members can be easily attached.

  The function of the plug 20 will be described. When the plug body 20 is closed, the plug body packing 48 of the plug body 20 is in contact with the opening 14 in a watertight manner as shown in FIGS. 1 and 2. In this state, when the plug body 20 is rotated in the direction to open the plug (the rotation rotates with the outer periphery of the plug cover 30), the plug cover 30 is attached to the inner case inner peripheral screw of the container body 10. 15 (in fact, the stopper ring outer peripheral screw 43 of the stopper ring 40 moves upward while rotating along the inner case inner peripheral screw 15 of the container body 10). It is lifted upward without rotating in conjunction with the cover 30.

  The reason why the unit object is lifted upward without rotating is that the unit object is prevented from rotating by the frictional force between the plug packing 48 and the opening 14. As a result, the so-called squeal generated by twisting the plug packing 48 is eliminated. After the plug packing 48 is separated from the opening 14, there is no frictional force to prevent rotation, and the unit object moves upward while rotating together with the plug cover 30.

  The same applies to the closing operation. In the closing operation, the unit object rotates with the plug cover 30 until the plug packing 48 and the opening 14 come into contact with each other. The unit object moves down without rotating, and the so-called squeak generated between the plug packing 48 and the opening 14 is eliminated.

  The upper plug 21, the plug cover 30, and the inner plug 50 can be disassembled, and each component can be disassembled and easily washed with a dishwasher or the like. Further, by disassembling the plug cover 30 into the plug cover main body 31 and the plug ring 40, the narrow annular groove 55 (see FIG. 2) formed between both members can be easily washed with a dishwasher or the like. Can do.

  Even if the plug cover 30 is a single member, it can be easily washed with a dishwasher or the like by disassembling into the upper plug 21, the plug cover 30, and the inner plug 50.

  The invention of the present application is not limited to the configuration of the above embodiment, and it is needless to say that the design can be appropriately changed without departing from the gist of the invention.
