Description
- 1. Field of the Invention
- The present invention relates to a cap body of a beverage container capable of directly drinking beverage in a container body by opening a lid with a touch.
- 2. Description of the Prior Art
- For example, a cap body disclosed in Japanese laid-open publication No. Hei 9-299253, which is cylindrically shaped and is releasably provided in a mouth portion of a container body, comprises a lid member connected via a hinge axis for opening and closing an upper opening, a spring for urging the lid member to the opening direction, and a lock member provided in a position diametrically against the hinge axis for maintaining the lid member in a closing state. The cap body is formed with a liquid-pouring passage in a distance from an inlet opening opened to an inside of the container body to an outlet opening reaching an upper opening. When the lock of the lid member is released, the lid member is opened by urging force of the spring, thereby it is possible to directly drink beverage in the container by setting one's lips to an peripheral wall of an upper opening of a drinking mouth member.
- However, in the above-mentioned constructions, since a diameter of the inlet opening of the liquid-pouring passage is large, especially when user tries to drink beverage by inclining the container body while getting on a vehicle, there exists such a problem that a large of amount of the beverage in the container flows out due to vibration or the like, to thereby soil user's clothes. Furthermore when hot beverage is put in the container, since an inlet opening area of the liquid-pouring passage is large, there exists such problem that a pressure applied to an inner cap of the lid member blocking the inlet opening becomes larger and then the lid member is vigorously released when the lock member is pressed. Moreover, in order to cope with the pressure applied to the lid member, strength and accuracy of the lock member are required.
- Furthermore, if the urging force of the spring is strong when the lock member of the lid member is released while user is holding the container body, there exist such problems that the lid member is vigorously opened to clash into a shoulder member of the cap body to thereby make user feel unpleasant impact on its hand or to make user feel unpleasant clash sound. If such clash is repeatedly occurred, there is such problem that an impact load is applied to a hinge axis supporting portion of the cap body, thereby the hinge axis supporting portion is damaged due to its long-time use. In addition, since the container body becomes lighter as the beverage in the container diminishes, the container body is shaken by an impact force to thereby fall down. On this account, it is necessary to consider a weight of the lid and a weight/height of a container body, particularly an impact force when the container body is empty, in selecting a spring. Thus, there exist such problems that it can't help selecting a spring having a limited urging force and a selection range of the spring becomes narrower. To the contrary, when the urging force of the spring is weak, there are such problems that the lid member is not sufficiently opened or the lid member slopingly opened for drinking falls down due to its weight.
- Therefore, the objective of the present invention is to provide a cap body of a beverage container where a large amount of beverage in a container body doesn't flow out due to vibration or the like, and the lid member is not vigorously released even if hot beverage is put in the container, and where a degree of freedom to select a spring for opening the lid member is improved by alleviating impact force in an opening operation of the lid member.
- In order to achieve the above-mentioned objective, according to the present invention, there is provided a cap body of a beverage container comprising: a cylindrically-shaped drinking mouth member releasably provided in a mouth portion of a container body; a lid member connected to the drinking mouth member via a hinge axis for opening and closing an upper opening of the drinking mouth member; a spring for urging the lid member to the opening direction; and a lock member provided in a position against the hinge axis of the drinking mouth member for maintaining the lid member in a closing state, wherein the drinking mouth member comprises a drinking mouth formed in the lock member side of a peripheral wall of the upper opening; a bottom wall where the drinking mouth side thereof is made lower and the hinge axis side thereof is made higher; a liquid hole formed in the drinking mouth side and an air hole formed in a hinge axis side on a connection line between the hinge axis side of the bottom wall and the lock member side; and the lid member comprises an inner cap provided with a seal member for sealing the liquid hole and the air hole. Furthermore, according to the present invention, it is preferred that an uppermost margin of the drinking mouth is formed in an uppermost position of an upper peripheral wall of the drinking mouth member.
- In addition, according to the present invention, there is provided a cap body of a beverage container comprising: a cylindrically-shaped shoulder member releasably provided in a mouth portion of a container body; a lid member for opening and closing an opening portion of the shoulder member; a hinge axis being inserted into a hinge-axis supporting portion of the shoulder member and a hinge-axis receiving portion of the lid member; a spring provided in the hinge axis for urging the lid member to the opening direction; and a lock member provided in a position diametrically against the hinge axis for maintaining the lid member in a closing state, wherein at least one of the hinge axis supporting portion or the hinge axis receiving portion is provided with a protrusion portion to which the lid member or the shoulder member slidably contacts, in an opening operation of the lid member. In the cap body thus constructed, it is preferred that the protrusion portion is such formed that a radial dimension thereof becomes gradually larger toward the opening direction of the lid member, and slidable contact between the protrusion portion and the lid member or the shoulder member is linear contact, and slidable contact area between the protrusion portion and the lid member or the shoulder member increases together with an opening operation of the lid member.

body receiving portion 41, in thelock member 8 side of an upper opening peripheral wall, comprises adrinking mouth 43 which is such formed that the peripheral wall of thelock member 8 side is made higher than the peripheral wall of thehinge axis 5 side. The uppermost margin of thedrinking mouth 43 is formed in the uppermost position of the upper peripheral wall. Furthermore, there is provided in a lower inner side of a cylindrical body of the cap body receiving portion 41 abottom wall 44 where thedrinking mouth 43 side thereof is made lower and thehinge axis 5 side thereof is made higher. In thebottom wall 44, there are respectively provided aliquid hole 45 in thedrinking mouth 43 side and anair hole 46 in thehinge axis 5 side on a connection line between thehinge axis 5 side and thelock member 8 side, to form aliquid passage 47 from thebottom wall 44 to the upper opening. Moreover, the outer periphery of the lower cylindrical body of the capbody receiving portion 41 is provided with apacking 48 for adhering closely to the inner peripheral wall of the mouth portion of thecontainer body 2. The inner periphery of the attachingportion 42 is formed with ascrew portion 49 threadably engaging thescrew portion 24 of thecontainer body 2. - The
lid member 6 comprises alid portion 61 for covering the upper opening of the capbody receiving portion 41 and aninner cap 62 provided in thelid portion 61 to be inserted into theliquid passage 47. Theinner cap 62 is provided with aseal member 63. Theseal member 63 results from integrally forming a flowing-outside seal portion 64 for adhering closely to the inner peripheral wall near the upper opening of theliquid passage 47, a flowing-inside seal portion 65 for closing theliquid hole 45 from the upper direction thereof and an air-hole seal portion 66 for closing theair hole 46 from the upper direction thereof. The tip end of thelid member 61 is provided with a hitchingnail 67 to be hitched to thelock member 8 and anengaging piece 68 to be engaged to alock ring 81 of thelock member 8. - The
lock member 8 comprises ahitching portion 82 at its upper portion and apressing portion 83 at its lower portion. The middle portion of thelock member 8 is rotatably supported by a horizontal supportingaxis 84 provided in the attachingportion 42. The hitchingportion 82 is always urged to the closing direction by aspring 85 wound on the supportingaxis 84. - According to the
cap body 3 thus constructed, when thepressing portion 83 of thelock member 8 is radially inwardly pressed from the closing state shown in FIG. 2, thehitching portion 82 of thelock member 8 is radially outwardly opened, and the engagement between theengaging portion 82 and theengaging nail 67 of thelid member 6 is released. Then, thelid member 6, as shown in FIG. 1 and FIG. 3, is rotatably opened to the upper direction by the urging force of thetorsion spring 7 to thereby make it possible to directly drink the beverage in thecontainer body 2 via thedrinking mouth 43 from theliquid hole 45 by inclining thebeverage container 1 with setting user's lip on thedrinking mouth 43. - At this time, since the uppermost margin of the
drinking mouth 43 is formed in the uppermost position of the upper peripheral wall of the capbody receiving portion 41, visibility of thedrinking mouth 43 is improved. Furthermore, the back surface of thelid member 6 doesn't contact user's face to thereby make it hygienic. In addition, since there exists a distance from theliquid hole 45 to thedrinking mouth 43, there becomes no such occasion that the beverage in the container quickly flows out, thereby it is possible to provide user with relief feeling. Furthermore, even if the beverage container is shakened due to a vibration when user drinks the beverage in container while getting on a vehicle, since the opening area of the liquid hole is narrow and there exists a distance between theliquid hole 45 and thedrinking mouth 43, there becomes no such occasion that a large amount of beverage in the container flows out. Moreover, since an opening area of theliquid hole 45 is narrower than those of prior arts when hot beverage is put in thecontainer body 2, a pressure applied to theinner cap 62 of thelid member 6 becomes smaller and then, there becomes no such occasion that thelid member 6 is vigorously released when thelid member 6 is opened. - Next, hereinafter, the present invention will be explained in detail based on the drawings of the second embodiment where a cap body of a beverage container comprises heat-insulating construction. FIG. 4 to FIG. 7 show the second embodiment of the present invention. A
beverage container 11, of a size capable of holding with one hand, comprises acontainer body 12 of a metallic dual heat-insulating construction, a synthetic-resin cap body 13 releasably mounted in a mouth portion of thecontainer body 12. Since thecontainer body 12 is such constructed that a metallicinner container 121 and a metallicouter container 122, where upper portions thereof are opened, are integrally joined at upper ends thereof, and a heat-insulatingportion 123 of a vacuum heat-insulating construction is provided between thecontainers container body 12 is formed with ascrew portion 124 threadably connecting thecap body 13. - The
cap body 13 comprises a cylindrically-shapedshoulder member 14 releasably attached at the mouth portion of thecontainer body 12 and alid member 17 connected to theshoulder member 14 via ahinge axis 16 for opening and closing an upper opening portion of theshoulder member 14. - The
shoulder member 14 comprises an attachingportion 141 threadably connected to thescrew portion 124 of thecontainer body 12, a capbody receiving portion 142 assembled with the attachingportion 141 to be inserted into the inner periphery of the mouth portion of thecontainer body 12. The attachingportion 141 is formed with a hingeaxis supporting portion 143 at its one side so that the central portion of ahinge axis 16 is supported by the hingeaxis supporting portion 143. Furthermore, a position diametrically against the hingeaxis supporting portion 143 is formed with alock member 18 for maintaining thelid member 17 in a closing state. The capbody receiving portion 142 is formed as a bottomed-cylindrical shape and results from respectively forming adrinking mouth 144 by making the peripheral wall of the upper opening of thelock member 18 side higher, aliquid hole 146 in thedrinking mouth 144 side of abottom wall 145 where the hingeaxis supporting portion 143 side thereof is made higher and thedrinking mouth 144 side thereof is made lower, and anair hole 147 in the hingeaxis supporting portion 143 side, to thereby form a liquid passage 148 from thebottom wall 145 to the upper opening. Furthermore, a lower outer periphery is formed with a packing 149 adhering closely to the inner peripheral wall of the mouth portion of thecontainer body 12. - The hinge
axis supporting portion 143, as shown in the cross-sectional view of FIG. 4, is integrally and continuously formed with the upper portion of the attachingportion 141 to be an approximate cylindrical shape in its cross-sectional plane, and has a horizontal hingeaxis inserting hole 151 at the central portion thereof. The hingeaxis supporting portion 143 is such formed, that when a radial dimension from the hingeaxis inserting hole 151 to the outer periphery may be divided as a front half portion over which thelid member 17 rotates into the opening direction and a rear half portion, the rear half portion is made to have a larger radius, to thereby form aprotrusion portion 152 on the outer periphery thereof. That is to say, a radial dimension R2 from the hingeaxis inserting hole 151 of the rear half portion to the outer periphery is made larger than a radial dimension R1 from the hingeaxis inserting hole 151 of the front half portion to the outer periphery, and theprotrusion portion 152 is such formed that the radial dimension thereof becomes gradually lager from the starting end side toward the rear side thereof. Moreover, the tip end of the starting end side of theprotrusion portion 152 is made as a sharpened triangle shape. - In both sides of the hinge
axis supporting portion 143, thehinge axis 16 is wound with atorsion spring 19 urging thelid member 17 into the opening direction. - The
lid member 17 comprises alid portion 171 covering the upper opening of the capbody receiving portion 142 and aninner cap 172 provided in thelid portion 171 to be inserted into the liquid passage 148. Thelid portion 171 is formed at its one side with hingeaxis receiving portions hinge axis 16, and the middle portion between the hingeaxis receiving portions axis supporting portion 143. The inserting concave portion 174 establishes a depth of aninner end portion 175 such that theinner end portion 175 lineally contacts theprotrusion portion 152 of the hingeaxis supporting portion 143 in the opening operation of thelid member 17. Moreover, in a position diametrically against the inserting concave portion 174, thelid portion 171 is formed with a hitchingportion 176 to be hitched to thelock member 18. Theinner cap 172 is provided with aseal member 177 for sealing theliquid hole 146 and theair hole 147 in a closing state. - The
lock member 18 is rotatably supported by a horizontal supportingaxis 181 provided in the attachingportion 141. An upper portion of the supportingaxis 181 is provided with a hitchingportion 182, and a lower portion thereof is provided with apressing portion 183 respectively. The hitchingportion 182 is always urged into the closing direction by aspring 184 wound on the supportingaxis 181. - According to the
cap body 13 thus constructed, when thepressing portion 183 of thelock member 18 is pressed, the hitchingportion 182 is outwardly opened, and the engagement between the hitchingportion 182 and the hitchingportion 176 of thelid member 17 is released. Then, thelid member 17 is upwardly rotated about thehinge axis 16 to be opened by the urging force of thetorsion spring 19. At this time, in a step that thelid member 17 is opened to be rotated from its upright state to the rear direction, theinner end portion 175 of the inserting concave portion 174 of thelid member 17 lineally and slidably contacts theprotrusion portion 152 of the hingeaxis supporting portion 143. Since the tip end of the starting end side of theprotrusion portion 152 is formed as a sharpened triangle shape, a contact area between theprotrusion portion 152 and theinner end portion 175 increases according to the opening operation of thelid member 17. Thus, a speed toward the opening direction of thelid member 17 decreases and then, the rotation of thelid member 17 is stopped before it collides with theshoulder member 14. - Therefore, an impact force in the opening operation of the
lid member 17 is alleviated, and an unpleasant impact is not applied to user's hand holding thecontainer body 12. Furthermore, since there become no need to consider strength of the urging force of thetorsion spring 19, it is possible to improve a degree of freedom in selecting thetorsion spring 19 to thereby decrease the manufacturing cost. Moreover, there becomes no such problems that the urging force of thetorsion spring 19 is too weak for the lid member to be sufficiently opened, or that thelid member 17 falls down due to failing to sustain its weight or inclining strength when the beverage container is inclined for drinking. - FIG. 8 shows the third embodiment of the present invention where a radial dimension from a hinge
axis inserting hole 151 of aprotrusion portion 152 at the hingeaxis supporting portion 143 to an outer periphery is such formed that a radial dimension R3 of a rear end side is gradually larger than a radial dimension R2 of a starting end portion thereof. Thus, in the opening operation of thelid member 17, as the rotation of thelid member 17 becomes larger, theinner end portion 175 of thelid member 17 strongly, lineally and slidably contacts theprotrusion portion 152 of the hingeaxis supporting portion 143, thereby the rotation of thelid member 17 is stopped before it collides with theshoulder member 14. - Therefore, it is possible to establish a rotation-stopping position of the
lid member 17 by considering changing the dimension from the radial dimension R2 of the starting end side of theprotrusion portion 152 toward the radial dimension R3 of the rear end side thereof. Moreover, it is possible to cope with such a case even that a depth of theinner end portion 175 of thelid member 17 is changed due to assembling error. - FIG. 9 and FIG. 10 show the fourth embodiment of the present invention. In this embodiment, similar to the second embodiment of the present invention, is characterized in that a tip end of a starting end side is formed as a sharpened triangle shape.
Protrusion portions 178, such formed that a radial dimension from a hingeaxis inserting hole 151 toward an outer periphery is made to be gradually larger over a rear half portion, are respectively formed in the hingeaxis receiving portions lid member 17 such that therespective protrusion portions 178 lineally and slidably contact the upper margin of theshoulder member 14 in the opening operation of thelid member 17. By such constructions, it is also possible to achieve the same effects as the previously-mentioned embodiments of the present invention. - As described above, since according to the present invention, the cap body comprises a cylindrically-shaped drinking mouth member releasably provided in a mouth portion of a container body; a lid member connected to the drinking mouth member via a hinge axis; a spring for urging the lid member to the opening direction; and a lock member provided in a position against the hinge axis of the drinking mouth member for maintaining the lid member in a closing state, wherein the drinking mouth member comprises a drinking mouth formed in the lock member side of a peripheral wall of the upper opening; a bottom wall where the drinking mouth side thereof is made lower and the hinge axis side thereof is made higher; a liquid hole formed in the drinking mouth side and an air hole formed in a hinge axis side on a connection line between the hinge axis side of the bottom wall and the lock member side, and the lid member comprises an inner cap provided with a seal member for sealing the liquid hole and the air hole, and since there exists a distance from the liquid hole to the drinking mouth, there becomes no such occasion that the beverage in the container quickly flows out thereby it is possible to provide one with relief feeling. Furthermore, even though the beverage container is shakened due to a vibration or the like when one tries to drink the beverage in the container while getting on a vehicle, since the opening area of the liquid hole is narrow and there exists a distance from the liquid hole to the drinking mouth, there becomes no such occasion that a large amount of beverage flows out. Moreover, since an opening area of the liquid hole becomes narrower than prior arts when hot beverage is put into the container body, a pressure applied to the lid member is smaller thereby there becomes no such occasion that the lid member is vigorously released when the lid member is opened. In addition, by forming the uppermost margin of the drinking mouth in the uppermost position of the upper peripheral wall of the drinking mouth member, it is possible to improve the visibility of the drinking mouth, and the back surface of the lid member doesn't contact one' face to thereby make it hygienic in drinking beverage.
- Moreover, according to the present invention, since the cap body of the beverage container connects a cylindrically-shaped shoulder member releasably provided in a mouth portion of a container body and a lid member for opening and closing an opening portion of the shoulder member by a hinge axis being inserted into a hinge-axis supporting portion of the shoulder member and a hinge-axis receiving portion of the lid member, and since the cap body provides a spring in the hinge axis for urging the lid member to the opening direction, and provides at least one of the hinge axis supporting portion or the hinge axis receiving portion with a protrusion portion to which the lid member or the shoulder member slidably contacts, in an opening operation of the lid member, when the lid member upwardly rotates about the hinge axis to be opened by the urging force of the spring, the lid member or the shoulder member slidably contacts the protrusion portion and a speed to the opening direction of the lid member decreases thereby the rotation of the lid member is stopped before it collides with the shoulder member. Thus, the impact force of the lid member in an opening operation is alleviated, and an unpleasant impact is not applied to one's hand holding the container body. Furthermore, since the urging force of the spring to open the lid member will do only if it is enough to open the lid member, it is possible to improve a degree of freedom in selecting the spring to thereby decrease the manufacturing cost.
