Description

  The present invention relates to a lid suitable for a beverage container such as a tumbler and a decanter, particularly for a container having heat retention.

  As a lid used for a tumbler, there is one disclosed in Patent Document 1 below. This lid is attached so as to fit almost entirely into the upper end opening of the tumbler, and has a cutout having a substantially rectangular shape in a plan view at a part in the circumferential direction. The notch is a liquid passage through which the liquid flows when drinking the liquid inside the beverage container, and a slide lid for opening and closing the liquid passage is provided above the liquid passage.

  Attaching such a lid to the tumbler has the advantages of preventing intrusion of dust and the like and improving the heat retaining function of the beverage container.

  However, after drinking the beverage with the lid attached, there is a possibility that the vicinity of the liquid hole of the lid becomes unsightly. That is, when drinking a beverage, the lips are attached to the upper edge of the beverage container and tilted, but the beverage spreads over the entire width of the liquid passage depending on the capacity of the beverage container. In this case, the beverage remains near the liquid passage when the beverage container is tilted. Beverages may enter between the slide lids. In addition, the remaining beverage is visible even when the slide lid is closed.

  Accordingly, it is a main object of the present invention to maintain a beautiful mouthpiece portion even after once drinking a beverage halfway.

Means for that are a lid body detachably attached to the opening at the upper end of the beverage container, and a lid of the beverage container having an opening and closing member slidably attached to the lid body, wherein the lid body is , and two through-hole penetrating vertically, and a hole forming part of these through-holes are formed, the outer peripheral wall portion erecting at the outer peripheral edge of the hole forming portion is formed, the through-hole, the lid body The through-holes are formed at two locations facing each other across the center of the outer peripheral portion, and one of the through-holes has a different shape as a drinking spout, and the other through-hole has a different shape as a straw insertion port. The hole forming portion having the through hole serving as a mouth has a three-dimensionally curved inclined surface in which the through hole is lowered below the center of the lid main body and the through hole is slightly lower, and the through hole is provided with the straw. The above-mentioned insertion port The through hole, which is formed at the lowest position in the hole forming portion leaving a wall at the through hole side portion and serves as the straw insertion port, is lower than the center of the lid main body and serves as the drinking port. A sliding concave portion is formed at a position higher than the through hole, a sliding concave portion is formed from end to end in a diameter portion passing through the center and the two through holes in the lid body, and the opening and closing member opens and closes the through hole. Attached to the sliding recess above the through hole so as to be slidable, and positioning the opening / closing member between a position where the through hole is opened and a position where the opening is closed between the lid body and the opening / closing member. A lid for a beverage container having a positioning structure formed therein, wherein the opening / closing member has a closed end which is close to the upper end of the outer peripheral wall from above when in the closed position.

  In this configuration, when the lid is attached to the beverage container, the lid closes the upper end opening, and only the through hole is a portion that allows communication between the inside and the outside of the beverage container. The through hole is closed when the opening / closing member is in the closed position, and is opened when the opening / closing member is in the open position. Since the positioning structure positions both the closed position and the open position of the opening / closing member, accidental closing and opening of the opening / closing member even when the opening / closing member is inclined can be prevented. Since the outer peripheral wall portion is provided on the outer peripheral edge side of the hole forming portion having the through hole, the through hole is formed relatively low due to the presence of the outer peripheral wall portion. When the opening and closing member is slid to the closed position, the closed end of the opening and closing member approaches the upper end of the outer peripheral wall from above. In other words, the beverage stops at the hole forming portion located at a position lower than the upper end of the outer peripheral wall portion, so that the beverage is prevented from rising further, and the closed end portion covers and covers the upper end of the outer peripheral wall portion.

Even drinking of the liquid droplets adhering to the straw previously when even removing the straw to drink by interpolating a straw into the through hole for straw fell around the through hole, the droplet in the same manner as described above in the hole forming element It stops and is hidden by closing the opening and closing member.

  ADVANTAGE OF THE INVENTION According to this invention, even if it drinks once halfway, it can suppress that a drink remains in a drinking-mouth part, and it can suppress a drinking-mouth part beautifully.

FIG. 4 is a plan view of a lid body having one through hole. FIG. 4 is a plan view of a lid body having another through hole.

One embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a state in which the lid 31 is attached to the beverage container 11. As shown in FIG. 2 with the lid 31 removed, the beverage container 11 shown in this example is a cup-shaped one having a bottomed cylindrical shape and an opening 12 at an upper end, and is made of a metal called a tumbler. It has a vacuum double structure. A large diameter portion 13 having a slightly larger diameter is formed on the inner peripheral surface of the opening 12 so that the lid 31 can be stably attached. The lower end of the large diameter portion 13 has an inclined surface 13a.

  The beverage container 11 may be a tumbler or another beverage container such as a decanter.

  The lid 31 is configured so that the beverage in the beverage container 11 can be delivered from two locations on the outer peripheral portion. Selection of a location for delivering the beverage is performed by sliding one member as shown by a virtual line in FIG. It can be done by motion.

  Such a lid 31 includes a lid main body 32 detachably attached to the opening 12 of the beverage container 11, and an opening / closing member 33 slidably attached to the lid main body 32. The lid body 32 and the opening / closing member 33 are made of synthetic resin.

  The lid main body 32 has a circular shape in plan view corresponding to the shape of the beverage container 11 in plan view, and a portion below the middle portion in the thickness direction fits into the large diameter portion 13 of the beverage container 11. For this reason, the lid main body 32 is formed on the outer peripheral surface of the lower part of the peripheral wall 35 having a short cylindrical shape, as shown in sectional views in FIGS. It has ribs 36 and 37 all around. FIG. 3 is a vertical cross-sectional view taken at a position passing through two centers for dispensing a beverage, and FIG. 4 is a vertical cross-sectional view taken at a center in a direction orthogonal to the vertical direction.

  The distance between the ribs 36 and 37 substantially corresponds to the height of the large diameter portion 13 of the beverage container 11. Specifically, when the lid 31 is fitted to the large diameter portion 13 of the beverage container 11, the lower rib 36 is located at the lower end of the large diameter portion 13 and the upper rib 37 is It is formed so as to have the same height. A packing 38 for stopping water between the ribs 36 and 37 and the beverage container 11 is held. Although a part of the lower rib 36 is cut off as shown in FIG. 3 (see FIG. 6), this is to make it easier to remove the packing 38.

  The portion of the peripheral wall 35 above the upper rib 37 is formed at an appropriate height so as to protrude upward on the inner peripheral side of the opening 12 of the beverage container 11 as shown in FIGS. 3 and 4. ing. In addition, the peripheral wall 35 is curved so as to slightly spread toward the outer peripheral side toward the upper end side.

  On the inner peripheral side of the peripheral wall 35, a partition wall portion 40 that partitions up and down is formed. Two through holes 41 and 42 penetrating vertically are formed in the partition 40. These through holes 41 and 42 are portions where the beverage is discharged, and have different shapes from each other. The different shape is a meaning including a case where only the size is different.

  Specifically, one through hole 41 has a circular shape in plan view, and the other through hole 42 has a substantially semi-elliptical shape in plan view. The circular through-hole 41 is formed in a size suitable for inserting the straw S, specifically, a size corresponding to the diameter of the straw S, as shown by a virtual line in FIG. The substantially semi-elliptical through hole 42 is used when directly drinking a beverage, and is formed in a shape that is easy to pour. This through hole 42 may be formed in an appropriate shape other than the substantially semi-elliptical shape.

  As shown also in FIGS. 5 and 6 which are perspective views, the formation positions of the through holes 41 and 42 are two locations facing each other across the center of the outer peripheral portion near the peripheral wall 35. A diameter portion passing through the center and the two through holes 41 and 42 is entirely concave with an appropriate width wider than the through holes 41 and 42. This concave portion is a sliding concave portion 43 to which the opening / closing member 33 is attached. The sliding recess 43 is formed to have a size that accommodates the opening / closing member 33.

  The bottom surface of the sliding concave portion 43 has an undulating shape, and the two hole forming portions 44 and 45 in which the through holes 41 and 42 are formed are lower than the height of the intermediate portion 46 therebetween. Further, the two hole forming portions 44 and 45 have different heights depending on the use of the through holes 41 and 42. Specifically, as shown in FIG. 3, one through hole 41 into which the straw S is inserted and used is formed at a position slightly lower than the height of the intermediate portion 46, and the other through hole 42 used to directly drink is , Is formed to be substantially lower than the height of the intermediate portion 46 and to be lowered to a position close to the height of the lower end of the peripheral wall 35. The hole forming portion 44 having the through hole 41 for the straw is formed flat, while the hole forming portion 45 having the through hole 42 for the direct drinking is three-dimensionally lowered toward the through hole 42 side. It has a curved inclined surface 45a. That is, the through hole 42 is formed at the lowest position in the hole forming portion 45. Due to the inclined surface 45a, even if the beverage returns to the hole forming portion 45, the beverage always falls down through the through hole 42.

  On the outer peripheral edge side of the two hole forming portions 44 and 45, outer peripheral wall portions 47 and 48 which are a part of the above-described peripheral wall 35 are formed. Of the outer peripheral wall portions 47, 48, the outer peripheral wall portion 47 adjacent to the straw through hole 41 is, as shown in FIGS. Low. As shown in FIG. 3, the upper end height of the outer peripheral wall portion 47 adjacent to the straw through hole 41 is the same as the upper surface height of the intermediate portion 46 on the bottom surface of the sliding concave portion 43.

  The above-mentioned opening / closing member 33 selectively opens and closes the two through holes 41 and 42, and is attached and detached so as to reciprocate diametrically above the upper surface height of the intermediate portion 46 on the bottom surface of the sliding concave portion 43. Mounted as possible.

  As shown in FIG. 5, the opening / closing member 33 has a substantially rectangular shape provided at both ends in the longitudinal direction with circular arcs in a plan view together with the lid main body 32 when the opening / closing member 33 is fitted in the sliding concave portion 43. A sliding piece 51 protrudes outward on both left and right sides in a direction perpendicular to the sliding direction so as to slide on a straight line. As shown in FIG. 6, the opening / closing member 33 is a pair of left and right urged outward in the left-right direction at a position below a pair of sliding pieces 51, specifically, immediately below a small gap. It has a set of engagement projections 52. The engagement projection 52 is formed on the outer side surface of the elastic frame 53 having a rectangular frame shape in a plan view, and its tip position protrudes slightly outward from the side position having the sliding piece 51, so that it is larger than the tip position of the sliding piece 51. It is the position where it retreated. The engagement protrusion 52 is formed at an intermediate position in the longitudinal direction of the opening / closing member 33.

  In order to attach such an opening / closing member 33, the lid main body 32 is positioned at a position corresponding to the sliding piece 51, that is, as shown in FIG. 5, at an upper end position of the outer peripheral wall portion 48 adjacent to the through hole 42 for drinking directly. A sliding groove 55 is provided on the upper side, and a plurality of sets of engaged portions 56, 57, 58 with which the engaging projections 52 are engaged are provided on both side surfaces below the sliding groove 55.

  As shown in FIGS. 3, 5, and 7, the engaged portions 56, 57, and 58 have an intermediate portion in the longitudinal direction of the sliding groove 55 and an end portion near the through hole 41 for the straw in the longitudinal direction. The position and the position close to the side of the through-hole 42 for direct drinking in the longitudinal direction.

  The engaged portion 56 at an intermediate position in the longitudinal direction positions the opening / closing member 33 at a closed position in which both the through holes 41 and 42 are closed. As shown in FIG. 8, the engaged portion 57 at the end portion close to the straw through hole 41 positions the opening / closing member 33 at an open position where only the drinking through hole 42 is directly opened. . The engaged portion 58 at a position closer to the side of the through hole 42 for drinking directly positions the opening / closing member 33 at an open position where only the through hole 41 for straw is opened as shown in FIG. Even if it is closed, the opening / closing member 33 does not seal hermetically, but has a clearance for sliding between the lid body 32 and the lid body 32, and allows ventilation.

  The engagement protrusion 52 and the engaged portions 56, 57, 58 are formed between the lid body 32 and the opening / closing member 33, and the opening / closing member 33 is closed at a position where the through holes 41, 42 are opened. This is a positioning structure for positioning at a predetermined position.

  As shown in FIG. 3, when the through holes 41 and 42 are in the closed position at the same time, the opening / closing member 33 closes the closed ends 61 and 62 that are close to the upper ends of the outer peripheral walls 47 and 48 from above. Have. Since the outer peripheral wall 48 adjacent to the through-hole 42 for direct drinking is high, the closed end 61 is formed thin, but the outer peripheral wall 47 near the straw through-hole 41 is low, so that the closed end 62 is small. Are formed vertically long. These closed ends 61 and 62 are shaped so as to fit into cutouts for forming the sliding recessed portions 43, and have no large gap other than the clearance. Since the closed ends 61 and 62 approach the upper ends of the outer peripheral walls 47 and 48 from above, the upper ends of the outer peripheral walls 47 and 48 are covered by the closed ends 61 and 62.

  As described above, the peripheral wall 35 having the outer peripheral wall portions 47 and 48 is curved so as to slightly expand toward the outer periphery toward the upper end. For this reason, the eaves 61a and 62a which protrude outward similarly to the peripheral wall 35 are formed in the outer peripheral edge of the upper end of the closed ends 61 and 62.

  The opening / closing member 33 slides in any direction in the longitudinal direction of the sliding concave portion 43, but as described above, the height of the two outer peripheral wall portions 47 and 48 and the height of the two closed end portions 61 and 62. Each is different. For this reason, in order to avoid the occurrence of breakage or the like due to forcible sliding operation, the upper surface of the sliding concave portion 43 on which the opening / closing member 33 slides in the lid main body 32, that is, the intermediate portion 46 on the bottom surface of the sliding concave portion 43. As shown in FIGS. 3 and 9, a stopper 65 that protrudes from the inner surface of the closed end 62 having the longer length of the opening / closing member 33 is protrudingly provided. As shown in FIG. 9, the stopper 65 is formed at a position where the straw through-hole 41 is opened, and more specifically, the engaged portion at a position closer to the aforementioned directly drinking through-hole 42. This is a position where the engaging projection 52 is engaged with the engaging projection 58. The height of the stopper 65 is set to a height less than the height of the sliding groove 55. The stopper 65 does not act in the direction of opening the through hole 42 for drinking directly, and if the opening and closing member 33 is further moved in the direction for opening the through hole 42 for drinking directly as shown in FIG. The opening / closing member 33 can be removed from the lid main body 32.

  In addition, the upper surface of the partition member 40 except for the upper surface of the opening / closing member 33 and the sliding concave portion 43 of the lid main body 32 has a gentle curved surface that is upwardly convex as a whole and has a uniform shape. At the center of the upper surface of the opening / closing member 33, a concave bowl-shaped recess 67 having a circular shape in a plan view is formed. The recess 67 is large enough to accommodate the abdomen of the thumb of the hand.

  The lid 31 configured as described above is used as follows.

  As described above, the thickness of the lid 31 may be set at the opening 12 of the beverage container 11 having the large-diameter portion 13 in the opening 12 or the opening 12 of the beverage container 11 having the size of the opening 12 which does not have the large-diameter portion 13. The lower part of the direction is fitted. In this state, since the peripheral wall 35 of the lid main body 32 extends above the upper rib 36, the opening / closing member 33 is located above the opening 12 of the beverage container 11.

  When the lid 31 is removed, the peripheral wall 35 extends upward and has a shape that spreads to the outer peripheral side, so that the fingertip is easily caught and easy to remove.

  At the time of attachment, the lid body 31 protects the beverage in the beverage container 11 from intrusion of dust and the like, and assists the function of keeping the beverage container 11 warm. Further, even when the beverage container 11 falls down, the lid 31 is attached to the beverage container 11 via the packing 38, so that the lid 31 does not come off easily, and the lid 31 suppresses a sudden outflow of a large amount of beverage. I do.

  When drinking a beverage, select a through hole to open depending on how you drink. When the beverage container 11 is tilted for drinking, the opening / closing member 33 of the lid 31 is horizontally moved to one side as shown in FIGS. 1 and 8 to directly open the through-hole 42 for drinking. The direction of movement of the opening / closing member 33 may be a direction in which the lower end 61 is pushed, and can be immediately recognized by visual observation. The movement of the opening / closing member 33 can be performed by pressing the closed end portion 61 or by hooking a finger on the concave portion 67 on the upper surface, so that any method can be taken according to the situation, and the operation is very convenient. Easy.

  When the opening / closing member 33 engaged in the closed position is moved, the engaging projection 52 is disengaged from the intermediate engaged portion 56, and the engaged projection 57 is moved to the engaged portion 57 near the straw through hole 41. The movement stops when 52 is engaged. By this positioning by the positioning structure, the through-hole 42 for direct drinking is kept open.

  When the beverage container 11 is tilted with a mouth attached to the through hole 42, the beverage flows out of the through hole 42. At this time, the other hole, that is, the straw through-hole 41 functions as an air hole, and enables smooth discharge without pulsation.

  Further, since the through-hole 41 is covered with the opening / closing member 33, the beverage does not splash on the face even if the through-hole 41 is suddenly greatly inclined. Therefore, safety can be ensured even for a hot beverage.

  When the beverage container 11 is set up after tilting the beverage container 11 and drinking a part of the beverage, the beverage to be returned into the beverage container 11 is accommodated in the hole forming portion 45, and passes through the through-hole 42 as it is, and the beverage container 11 Return to That is, it is possible to prevent the beverage from entering the middle portion 46 on the bottom surface of the sliding recess 43. In addition, since the outer peripheral wall 48 extends above the opening 12 of the beverage container 11, it is possible to prevent the beverage from adhering to the opening of the beverage container 11 even if the user drinks with a mouth. Therefore, the beverage does not remain in the peripheral portion of the through hole 42.

  Further, after such a beverage operation, when the opening / closing member 33 is moved to the closed position to directly close the through hole 42 for drinking, the upper end of the outer peripheral wall portion 48 is concealed by the closed end portion 61. Can also make the appearance beautiful. In addition, since the closed end 61 is provided with the eaves 61a, the concealing property is further enhanced, and the dust and the like can be prevented from adhering to the outer peripheral wall 48.

  In the operation of closing the closing member 33, since the longitudinal end of the closing member 33 protrudes to the outer peripheral side from the beverage container 11, the work is performed in comparison with the case where the closing member 33 is within the opening area of the beverage container 11. It's easy to do.

  In the case of drinking a beverage with a straw, the high end portion 62 of the opening / closing member 33 is pushed in and the through hole 41 for the straw is opened as shown in FIG. When the opening / closing member 33 engaged in the closed position is moved, the engaging projection 52 is disengaged from the intermediate engaged portion 56, and the opening / closing member 33 is directly engaged with the engaged portion 58 at a position close to the drinking through hole 42. The movement stops when the engagement projection 52 is engaged. At this time, the opening / closing member 33 is also restricted by the stopper 65. Through the positioning by the positioning structure, the straw through-hole 41 is kept open.

  When drinking, the straw S is inserted into the through hole 41 and sucked. Suction can be performed smoothly even if the through hole 41 is small, because the other hole, that is, the through hole 42 for direct drinking functions as a ventilation hole. Further, since the size of the through hole 41 is a size corresponding to the straw S, the insertion posture of the straw S is stabilized. Therefore, it is very easy to drink even while operating a personal computer or driving a car. Moreover, since the through hole 42, which is the larger hole, is covered with the opening / closing member 33, dust and the like do not enter through the through hole 42.

  Further, since the hole forming portion 44 having the through hole 41 has the outer peripheral wall portion 47, in other words, it is formed one step lower, so that when the straw S is taken out, it adheres to the tip of the straw S. If the liquid falls, it does not run out. If the amount of liquid is sufficient to flow, the liquid returns from the through hole 41 into the beverage container 11. Moreover, as described above, since the closed end portion 62 is formed on the opening / closing member 33, when the opening / closing member 33 is closed, the inside and the upper end of the outer peripheral wall 47 are hidden, and are protected from dust and the like.

  The through-hole 41 for the straw may be used directly for drinking with a mouth.

  As described above, it is possible to suppress the beverage from remaining or being visible in the drinking spout even after the beverage has been drunk halfway, and to keep the drinking spout visually and substantially beautifully. In addition, the beverage can be drunk in two ways, and the above-mentioned advantages can be obtained in any case.

  Further, since the opening / closing member 33 can be detached from the lid main body and the opening / closing member 33 and the lid main body 32 have simple shapes, cleaning is easy.

  The configuration in the above description is one mode for carrying out the present invention, and the present invention is not limited to only the above-described configuration, and other configurations can be adopted.

  For example, the sliding of the opening / closing member does not slide on a straight line but may rotate.

  Further, the opening / closing member may be slid within a range within the plan view of the lid so as not to protrude to the outer peripheral side when the through hole is opened.

  The fitting of the lid to the beverage container may be an outer fitting.
