Description

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

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

  When such a lid is attached to the tumbler, there is an advantage that it is possible to prevent intrusion of dust and the like and to improve the heat retaining function of the beverage container.

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

Japanese Patent Laying-Open No. 2015-166258

  Therefore, the main object of the present invention is to keep the mouth portion beautiful even after the beverage has been drunk halfway.

  Means therefor are a lid body of a beverage container provided with a lid body detachably attached to the opening at the upper end of the beverage container, and an opening / closing member slidably attached to the lid body. At least one through-hole penetrating vertically, a hole-forming portion in which the through-hole is formed, and an outer peripheral wall portion standing on the outer peripheral side of the hole-forming portion, and the opening / closing member passes through the through-hole Positioning that is slidably mounted above the through hole to open and close, and that positions the open / close member between the lid body and the open / close member at a position where the through hole is opened and closed A lid of a beverage container having a structure and having a closed end which is close to the upper end of the outer peripheral wall from above when the opening / closing member is in a 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 becomes a portion that allows communication between the inside and the outside of the beverage container. The through hole is closed when the open / close member is in the closed position, and is opened when the open / close member is in the open position. Since the positioning structure positions both the closing position and the opening position of the opening / closing member, the opening / closing member is prevented from being unexpectedly closed or opened even if it is tilted. And since the outer peripheral wall part is provided in the outer-periphery edge side of the hole formation part which has a through hole, the through hole is formed relatively low by presence of an outer peripheral wall part. When the open / close member is slid to the closed position, the closed end of the open / close member approaches the upper end of the outer peripheral wall from above. That is, the beverage stops at the hole forming portion located at a position lower than the upper end of the outer peripheral wall portion, and is prevented from rising further, and the closed end portion covers the upper end of the outer peripheral wall portion.

  The through hole may have a size corresponding to the diameter of the straw, or may be provided with both a through hole for a straw and a through hole that can be directly drunk with a mouth. Even if a straw is inserted into a through hole for drinking through a straw and the beverage drops attached to the tip of the straw when the straw is pulled out, the liquid droplets remain in the hole forming part as described above. If the opening and closing member is closed, it is concealed.

  According to the present invention, it is possible to prevent the beverage from remaining or visible in the mouth portion even after the beverage has been drunk halfway, and the mouth portion can be kept beautiful.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of the beverage container 11 with a lid 31 attached. As shown in FIG. 2 with the lid 31 removed, the beverage container 11 shown in this example is a cup-shaped cup having a bottomed cylindrical shape and having an opening 12 at the upper end, and is made of a metal called a so-called tumbler. 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.

  In addition to the tumbler, the beverage container 11 may be another beverage container such as a decanter.

  The lid 31 is configured so that the beverage in the beverage container 11 can be taken out from two places on the outer peripheral portion, and the selection of the position where the beverage is taken out is made by sliding one member as shown by the phantom line in FIG. It can be done alternatively.

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

  The lid body 32 has a circular shape in plan view corresponding to the shape in plan view of the beverage container 11, and the lower portion of the lid body 32 is fitted to the large diameter portion 13 of the beverage container 11 in the thickness direction. For this reason, the lid body 32 is formed of two pieces formed on the outer peripheral surface of the lower portion of the peripheral wall 35 having a short cylindrical shape with a vertical interval as shown in FIGS. Ribs 36 and 37 are provided over the entire circumference. FIG. 3 is a longitudinal sectional view cut at a position passing through the center of two places where the beverage is served, and FIG. 4 is a longitudinal sectional view cut at the center in a direction orthogonal to the center.

  The interval 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 positioned at the lower end portion of the large diameter portion 13, and the upper rib 37 is connected to the opening portion 12. It is formed to be the same height. Between these ribs 36 and 37, a packing 38 for holding water with the beverage container 11 is held. As shown in FIG. 3, a part of the lower rib 36 is cut away (see FIG. 6). This is for making it easy to remove the packing 38.

  As shown in FIGS. 3 and 4, 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. ing. Further, the peripheral wall 35 is curved so as to spread slightly toward the outer peripheral side toward the upper end side.

  A partition wall 40 is formed on the inner peripheral side of the peripheral wall 35 to partition vertically. Two through holes 41 and 42 penetrating vertically are formed in the partition wall 40. These through holes 41 and 42 are portions for serving beverages and have different shapes. The different shapes mean that only different sizes are included.

  Specifically, one through hole 41 is circular in plan view, and the other through hole 42 is substantially semi-elliptical in plan view, which is larger than that. 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 indicated by phantom lines in FIG. The substantially semi-elliptical through hole 42 is used when drinking a beverage directly, and is formed into a shape that is easy to pour. The through hole 42 may be formed in an appropriate shape other than a substantially semi-elliptical shape.

  The through holes 41 and 42 are formed at two locations facing each other across the center of the outer peripheral portion close to the peripheral wall 35 as shown in FIGS. 5 and 6 which are perspective views. The diameter portion passing through the center and the two through holes 41 and 42 is entirely recessed with an appropriate width wider than the through holes 41 and 42. This recessed portion is a sliding recess 43 to which the opening / closing member 33 is attached. The sliding recess 43 is formed in a size that can accommodate the opening / closing member 33.

  The bottom surface of the sliding recess 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 used by inserting the straw S is formed at a position slightly lower than the height of the intermediate portion 46, and the other through hole 42 used for direct drinking is The height is considerably lower than the height of the intermediate portion 46 and is lowered to a position close to the height of the lower end of the peripheral wall 35. In addition, the hole forming portion 44 having the through hole 41 for the straw is formed flat, whereas the hole forming portion 45 having the through hole 42 for drinking directly 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. Even if the beverage returns to the hole forming portion 45, the inclined surface 45a always falls down through the through hole 42.

  On the outer peripheral side of the two hole forming portions 44 and 45, outer peripheral wall portions 47 and 48 that are part of the peripheral wall 35 are formed. Of the outer peripheral wall portions 47 and 48, the outer peripheral wall portion 47 adjacent to the straw through hole 41 is more than the outer peripheral wall portion 48 adjacent to the direct drinking through hole 42 as shown in FIGS. Low. As shown in FIG. 3, the upper end height of the outer peripheral wall portion 47 adjacent to the through hole 41 for the straw is the same as the upper surface height of the intermediate portion 46 at the bottom surface of the sliding recess 43.

  The aforementioned opening / closing member 33 selectively opens and closes the two through holes 41, 42, and is attached and detached so as to reciprocate in the diametrical direction above the upper surface height of the intermediate portion 46 at the bottom surface of the sliding recess 43. Installed as possible.

  As shown in FIG. 5, the opening / closing member 33 has a substantially strip shape with arcs that are circular in plan view together with the lid main body 32 when fitted in the sliding recess 43, along the longitudinal direction. In order to slide on a straight line, the slide piece 51 protrudes outward on the left and right sides in the direction orthogonal to the sliding direction. Further, as shown in FIG. 6, the opening / closing member 33 is a pair of left and right urged outwards in the left-right direction at a position below the pair of sliding pieces 51, specifically just below a slight gap. A set of engaging protrusions 52 is provided. The engagement protrusion 52 is formed on the outer side surface of the elastic frame 53 having a rectangular frame shape in plan view, the tip position slightly protrudes from the side surface position having the sliding piece 51, and is more than the tip position of the sliding piece 51. It is a retracted position. 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 body 32 is located at a position corresponding to the sliding piece 51, that is, at the upper end position of the outer peripheral wall portion 48 adjacent to the through hole 42 for direct drinking as shown in FIG. A sliding groove 55 is provided on the upper side, and a plurality of sets of engaged portions 56, 57, and 58 with which the engaging protrusions 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 intermediate positions in the longitudinal direction of the sliding groove 55 and end portions close to the through hole 41 for the straw in the longitudinal direction. There are three positions: a position and a position close to the through hole 42 for direct drinking in the longitudinal direction.

  The engaged portion 56 at an intermediate position in the longitudinal direction is for positioning the opening / closing member 33 at a closed position where both of the through holes 41 and 42 are closed. As shown in FIG. 8, the engaged portion 57 at the end position close to the straw through hole 41 is for positioning the opening / closing member 33 at an open position where only the through hole 42 for drinking is directly opened. . As shown in FIG. 9, the engaged portion 58 at a position close to the direct drinking through hole 42 side positions the opening / closing member 33 at an open position where only the straw through hole 41 is opened. Even if it is closed, the opening / closing member 33 is not hermetically sealed but has a clearance for sliding between the lid main body 32 and ventilation.

  The engaging 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. It is a positioning structure for positioning at a certain position.

  In addition, as shown in FIG. 3, the opening / closing member 33 has closed end portions 61 and 62 that are close to the upper end of the outer peripheral wall portions 47 and 48 from above when the through holes 41 and 42 are simultaneously in the closed position. Have. Since the outer peripheral wall portion 48 adjacent to the directly drinking through hole 42 is high, the closed end portion 61 is formed thin, but the outer peripheral wall portion 47 in the vicinity of the through hole 41 for straw is low, so the closed end portion 62 is formed. Are formed long vertically. These closed end portions 61 and 62 have a shape corresponding to the notch portion for forming the sliding recess 43, and there is no large gap other than the clearance. Since the closed end portions 61 and 62 are close to the upper ends of the outer peripheral wall portions 47 and 48 from above, the upper ends of the outer peripheral wall portions 47 and 48 are covered by the closed end portions 61 and 62.

  As described above, the peripheral wall 35 having the outer peripheral wall portions 47 and 48 is curved so as to spread slightly toward the outer peripheral side toward the upper end side. For this reason, flange portions 61 a and 62 a protruding outward are formed on the outer peripheral edges of the upper ends of the closed end portions 61 and 62 in the same manner as the peripheral wall 35.

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

  Further, the upper surface of the partition wall portion 40 excluding the upper surface of the opening / closing member 33 and the sliding recess 43 of the lid main body 32 is a gently curved surface convex upward as a whole and has a uniform shape. In the center of the upper surface of the opening / closing member 33, a concave recess 67 having a circular shape in plan view is formed. The recess 67 is large enough to accommodate 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 is adjusted to the beverage container 11 having the large diameter portion 13 in the opening portion 12 or the opening portion 12 of the beverage container 11 in which the size of the opening portion 12 matches even if the large diameter portion 13 is not provided. Fit the lower part in the vertical direction. In this state, since the peripheral wall 35 of the lid body 32 extends above the upper rib 36, the opening / closing member 33 is positioned above the opening 12 of the beverage container 11.

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

  At the time of attachment, the lid 31 protects the beverage in the beverage container 11 from intrusion of dust or the like, and helps the heat retaining function of the beverage container 11. Even when the beverage container 11 falls, the lid body 31 is attached to the beverage container 11 via the packing 38, so that the lid body 31 does not easily come off, and the lid body 31 suppresses a sudden flow of a large amount of beverage. To do.

  When drinking, choose a through hole that opens depending on how you drink. When drinking with the beverage container 11 tilted, 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 moving direction of the opening / closing member 33 may be a direction in which the closed end 61 having the lower height is pushed, and can be recognized immediately by visual observation. The opening / closing member 33 can be moved either by pushing the closed end 61 or by hooking a finger to the recess 67 on the upper surface, so that either method can be used depending on the situation, and the operation is very Simple.

  When the opening / closing member 33 engaged in the closed position is moved, the engagement protrusion 52 is removed from the intermediate engaged part 56 and the engagement protrusion 57 is located near the straw through hole 41. The movement stops when 52 is engaged. By this positioning by the positioning structure, the directly drinking through hole 42 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 pouring without pulsation.

  Moreover, since the through-hole 41 is covered with the opening / closing member 33, even if it is suddenly inclined greatly, the beverage does not hit the face. For this reason, even if it is a hot drink, safety can be ensured.

  When the beverage container 11 is stood after the beverage container 11 is tilted to drink 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. Return to the inside. That is, it is possible to prevent the beverage from entering the intermediate portion 46 on the bottom surface of the sliding recess 43. And since the outer peripheral wall part 48 has extended above the opening part 12 of the drink container 11, it can avoid that a drink adheres to the opening part of the drink container 11 even if it attaches and drinks. For this reason, 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 and the through-hole 42 for drinking is directly closed, the upper portion of the outer peripheral wall portion 48 is concealed by the closed end portion 61. The appearance can also be beautiful. In addition, since the flange portion 61 a is formed on the closed end portion 61, the concealing property is further enhanced, and dust and the like can be prevented from adhering to the outer peripheral wall portion 48.

  The operation of closing the closing member 33 is performed in comparison with the case where the end of the closing member 33 in the longitudinal direction protrudes to the outer peripheral side of the beverage container 11, as compared with the case where it is within the opening area of the beverage container 11. It's easy to do.

  When drinking a drink with a straw, contrary to the above, the closed end 62 with a high height of the opening / closing member 33 is pushed in to open the through hole 41 for the straw as shown in FIG. When the opening / closing member 33 engaged in the closed position is moved, the engaging protrusion 52 is removed from the intermediate engaged portion 56 and is directly moved to the engaged portion 58 close to the drinking through hole 42. The movement stops when the engaging protrusion 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, since another hole, that is, the through hole 42 for direct drinking functions as a vent hole. Moreover, 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. For this reason, it is very easy to drink 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 or the like does not enter from the through hole 42.

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

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

  As described above, it is possible to prevent the beverage from remaining or visible in the mouth portion even after the beverage has been drunk halfway, and the mouth portion can be kept visually and substantially beautiful. Moreover, in addition to being able to drink beverages in two ways, the above-described advantages can be obtained in any case.

  In addition, the opening / closing member 33 can be removed from the lid body, and the opening / closing member 33 and the lid body 32 have a simple shape, so that cleaning is easy.

  The structure in the above description is one form for implementing this invention, This invention is not limited only to the above-mentioned structure, Other structures can also be employ | adopted.

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

  Further, the opening / closing member may slide within a range that fits in 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 external fitting.
