Description

  The present invention relates to a cap with a lid lock function that protects a lid body of a cap attached to a mouth portion of a container.

  An advantage of a hinge cap having a lid that is hinged to the cap body so as to be opened and closed is that the lid can be easily opened and closed without applying force. Therefore, such a hinge cap is widely used in the technical fields such as cosmetics and foods as a member from which the internal composition filled in the container can be easily taken out.

  In particular, in the technical field of cosmetics, it is often applied to products that are carried in a basket, such as deodorant lotion and skin lotion.

  However, since the conventional hinge cap can be easily opened and closed, there is a problem that the lid is easily opened due to an external factor that is not human power. Specifically, for example, when carrying in a bag, if the bag hits something while walking, or if the bag is vigorously placed on a desk, floor, etc., the bag is impacted and other storage in the bag There was a problem that the hinge cap was opened by colliding with an object and the internal composition leaked out.

  For this reason, attempts have been made to provide a hinge cap with a locking mechanism for reliably maintaining the closed state in order to prevent unintentional opening (for example, see Patent Document 1).

  In Patent Document 1, a cap body that is attached to a container body neck and neck and includes a lid housing recess that longitudinally cuts the top center portion back and forth, and an opening is provided in the lid housing recess, and a spout And the rear part is pivotably connected to the rear part of the cap body so that it can be opened and closed, and the front part exposed to the opening at the front end of the lid housing recess And a lid that is provided with a finger hook, and is rotatably fitted around the cap body and the lid, and the opening at the front end of the lid housing recess is opened and closed on the base cylinder that surrounds the periphery of the cap body There is disclosed a cap with a lock mechanism provided with a rotating body having a covering plate portion that can be covered upright.

  That is, the cap with a lock mechanism described in Patent Document 1 is provided with a cover plate portion of a rotating body that is a movable wall surface on the side surface of the hinge cap, and the cover plate portion is hinged by rotating the rotary body by 90 degrees. By covering the hinge portion of the cap, the opening / closing operation of the hinge portion is inhibited.

JP 2010-274959 A

  According to the cap with a lock mechanism described in Patent Document 1, in order to suppress the opening and closing of the hinge portion by the covering plate portion, the clearance between the covering plate portion and the lid is made as narrow as possible, and when opening and closing. In addition, it is necessary to closely attach the covering plate portion to the hinge portion of the lid. Therefore, in order to obtain such adhesion, it is necessary to limit the shape of the hinge part and the lid part to a shape with good adhesion, and there is a problem that the degree of freedom in design is limited.

  The cap with a lock mechanism described in Patent Document 1 is a mechanism that covers (locks) only the hinge portion that is the rear end portion of the lid body, and the front end portion of the lid body that is the side to be opened and closed. There is no locking mechanism and it is easy to open. Therefore, when the lock at the rear end portion is weak (that is, the adhesiveness is low), there is a problem that the front end portion side of the lid may be opened due to a slight external factor.

  The present invention was devised to solve such a problem, and its purpose is to be a lock structure that directly presses the lid from above, and even if various external factors are added, it is closed. An object of the present invention is to provide a cap with a lid locking function that can reliably prevent the lid from opening unexpectedly.

  In order to solve the above problems, the cap with a lid lock function according to the present invention is supported by a cap body having a cylindrical outer peripheral portion to be attached to a mouth portion of a container and a lid housing recess provided at an upper portion of the cap body. A lid provided in a freely openable / closable manner through a portion, and a cap cover that is rotatably mounted along the outer peripheral portion of the cap main body and has an inner peripheral portion that is open at the top, and the lid The body is formed in a shape other than a circle in a plan view, and the cap cover has an upper opening edge extended to a position above the closed lid body and extended. A lid pressing piece extends from the opening edge toward the top of the lid.

  According to the invention, the lid pressing piece rotates the cap cover from the opening / closing position without overlapping the upper portion of the lid at the opening / closing position where the cap cover can open / close the lid. It may be configured to move to a position where the upper part of the lid overlaps.

  According to this configuration, when the cap cover is slightly rotated in the right or left direction from the open / closed position, the shape of the opening of the cap cover is shifted in the rotation direction with respect to the shape of the lid. That is, with this rotation, the lid pressing piece moves to the upper part of the lid, and the lid is pressed from above so that the lid is reliably prevented from being opened. That is, the closed lid can be reliably locked.

  Moreover, according to this invention, the said cover body is good also as a structure by which at least one part of the outer peripheral part or two opposing sides was formed in curvilinear form or linear form other than a circular arc.

  Further, according to the present invention, the cap cover has an opening edge recessed downward on a peripheral side surface facing an operation portion for opening and closing the lid body at an opening and closing position where the lid body can be opened and closed. A front opening recess is formed, and on the peripheral side surface facing the support portion of the lid, the opening edge is recessed downward to form a rear opening recess, and the width of the rear opening recess is The width of the support portion is wider than the width of the support portion.

  According to this configuration, since the operation unit on the front side and the support unit on the rear side of the lid body are exposed from the cap cover at the opening / closing position of the lid body, the lid body can be smoothly opened and closed. In addition, since the width of the rear opening recess is wider than the width of the support portion, even if the cap cover rotates unexpectedly with the lid open, the cap cover is not supported by the support portion (for example, resin The hinge part integrally formed in the case is not immediately hit, and there is a slight margin until it hits, so that it is possible to reduce damage to the support part in the event of an unexpected situation such as rotating with the lid open. .

  Further, according to the present invention, a protruding portion is formed on one of the outer peripheral portion of the cap body and the inner peripheral portion of the cap cover, and on the other side, an arc shape in which the protruding portion fits and slides. Or it is good also as a structure in which the annular groove part was formed.

  According to this configuration, the cap cover can be smoothly rotated with respect to the cap body.

  Further, according to the present invention, the groove portion may be formed with a first rib piece over which the protrusion hits and gets over.

  According to this configuration, when the cap cover is rotated, a click feeling is transmitted to the operator's hand as the protruding portion gets over the first rib piece, so that it can be realized that the cap cover is reliably rotated to that position. Therefore, the cap cover can be rotated stepwise by forming such first rib pieces at a plurality of locations in the groove.

  Moreover, according to this invention, it is good also as a structure by which the 2nd rib piece which controls the rotational movement of the said projection part was formed in the said groove part.

  The cap cover may be configured to rotate 360 degrees freely by making the groove part annular, but if it is rotated to a position where it is securely locked, the rotation is restricted there, and no further rotation is performed. Two rib pieces may be formed.

  Further, according to the present invention, the outer peripheral portion of the cap main body or the inner peripheral portion of the cap cover in which the groove portion is formed has a vertical groove reaching the groove portion from the upper end portion at a position corresponding to the protrusion portion. A third rib piece is formed at a position immediately above the groove portion of the vertical groove, and a third rib piece is formed in which the protrusion slides in the vertical groove and climbs to the groove portion side. Is configured such that the protrusion fitted in the groove does not return to the longitudinal groove.

  According to this configuration, the mounting property when the cap cover is mounted on the cap body is improved, and a mounting structure that does not easily come off after being mounted once can be obtained.

  According to the present invention, after the lid is closed, the cap cover is reliably rotated and the upper part of the closed lid is reliably pressed by rotating the cap cover in an arbitrary direction, so that the closed lid opens unexpectedly. This can be suppressed. That is, the closed state can be reliably maintained (locked). Moreover, according to this invention, the upper part of the cover body closed by the cover body pressing piece can be reliably pressed down only by slightly rotating the cap cover.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1A is a perspective view showing a cap with a lid locking function according to an embodiment of the present invention from a perspective from above, and FIG. 1B shows a cap with a lid locking function according to an embodiment of the present invention from a perspective from below. FIG. 1C is a sectional view taken along line AA in FIG. 1A.

  The cap 1 with a lid lock function according to the embodiment of the present invention has a cap body 10 having a cylindrical outer peripheral portion to be attached to the mouth portion of the container and a support portion on the upper portion of the cap body 10 facing the mouth portion of the container. And a cap cover 30 that is rotatably mounted along the outer peripheral portion of the cap body 10. In other words, the cap 1 with a lid lock function of the present invention is composed of two members: a cap body 10 integrally provided with a lid body 20 and a cap cover 30 rotatably mounted on the cap body 10.

(1) Description of Cap Body 10 FIG. 2A is a perspective view showing the cap body 10 constituting the cap 1 with a lid locking function according to the embodiment from a perspective from above, and FIG. 2B is a lid locking function according to the embodiment. FIG. 2C is a plan view of the cap body 10 according to the embodiment, and FIG. 2D is a side view of the cap body 10 according to the embodiment. FIG. 2E is a perspective view showing a state in which the lid 20 of the cap body 10 according to the embodiment is opened from a perspective from obliquely above.

  The cap main body 10 is a portion that is externally fitted to a mouth portion (not shown) that protrudes in a cylindrical shape from the container main body, and is entirely formed in a substantially cylindrical shape according to the mouth portion.

  The lower part of the cap body 10 is a mounting part whose bottom surface to be attached to the mouth part is opened, and the inner peripheral part thereof is screwed into a spiral male screw part formed on the outer peripheral part of the mouth part. A spiral female thread portion 11 is formed. However, the mounting structure between the mouth portion and the cap body 10 is not limited to such a screw structure, and various conventionally known mounting structures can be employed.

  Here, in the present embodiment, in a state where the cap body 10 is mounted on the mouth of the container, the direction viewed from the front of the container is defined as the front-rear direction, and the direction orthogonal thereto is defined as the left-right direction.

  On the upper part of the cap body 10, a lid housing recess 12 for housing the lid 20 so as to be freely opened and closed is provided. In the present embodiment, the lid housing recess 12 is open in the front-rear direction and has a shape in which straight side wall portions are provided in parallel in the left-right direction. The opening in the front-rear direction has an arc shape along the outer periphery of the cap body 10. Accordingly, the lid housing recess 12 has a substantially elliptical shape having a straight portion in plan view, and has a symmetrical shape when viewed from the front side.

  The rear end portion of the lid housing recess 12 is a stepped portion 12a that is recessed inward from the outer peripheral portion of the cap body 10, and is a support portion that supports the lid 20 so as to be freely opened and closed by the stepped portion 12a. A hinge part 13 is provided (refer mainly to FIGS. 2C and 2D). In addition, a discharge port 14 for discharging the internal composition stored in the container is provided on the bottom surface of the lid housing recess 12.

  The lid 20 has a shape that fits into the lid housing recess 12 (that is, a shape other than a circle in plan view). Specifically, the front side is an arc-shaped finger-hanging portion 21, and linear side wall portions 22, 22 are formed in parallel from the left and right sides of the finger-hanging portion 21 toward the rear, and both side wall portions 22, 22 are formed. The rear end portions are connected by a straight rear wall portion 23. That is, the lid 20 has a symmetrical shape when viewed from the front side. And it has the structure by which the hinge part 13 which is an opening-and-closing axis was provided over the back wall part 23 and the level | step-difference part 12a of the cover body recessed part 12. FIG. In the present embodiment, the cap body 10 and the lid body 20 are formed by integral molding with resin including the hinge portion 13. However, the hinge portion 13 may be a structure in which the cap body 10 and the lid body 20 are connected to each other in a freely openable and closable manner using a rod-shaped support shaft (pin) instead of being integrally formed with resin. That is, the opening / closing mechanism of the lid 20 is not particularly limited, and various conventionally known opening / closing mechanisms can be employed.

  The lid 20 is configured to be substantially flush with the upper surface 10b of the cap body 10 in the state of being accommodated in the lid housing recess 12 (that is, the lid 20 is closed). In addition, the lid 20 seals the discharge port 14 provided on the bottom surface of the lid housing recess 12 in the closed state housed in the lid housing recess 12.

  An arcuate or annular groove 15 is formed on the outer peripheral portion of the cap body 10, and a plurality of first rib pieces 16 are formed in the groove 15. In addition, about the groove part 15 and the 1st rib piece 16, it is a part relevant to the cap cover 30, and since it is not a part directly related to the lid lock function which restricts opening and closing of the cover body 20, in the description of the click mechanism mentioned later. Detailed description. Further, in the present embodiment, the case where the groove portion 15 is annular, that is, a case where the groove portion 15 is formed in a series over the entire circumference of the outer peripheral portion of the cap body 10 will be described, and the case where the groove portion 15 has an arc shape will be described later. To do.

(2) Description of Cap Cover 30 FIG. 3A is a perspective view showing the cap cover 30 constituting the cap with a lid lock function according to the embodiment from a perspective from above, and FIG. 3B is a bottom view of the cap cover 30. .

  The cap cover 30 is attached to the cap body 10 so as to be externally mounted, and is provided so as to be rotatable along the outer periphery of the cap body 10. Therefore, the cap cover 30 has both a lower part and an upper part opened, and at least an inner peripheral part is formed in a cylindrical shape. In the embodiment, the entire cap cover 30 is formed in a substantially cylindrical shape according to the shape of the cap body 10. However, the outer peripheral shape of the cap cover 30 is not necessarily a cylindrical shape, and various shapes can be used in consideration of design and operability. For example, in terms of design, it is conceivable to change the outer peripheral shape to a star shape, a petal shape, a continuous waveform shape or the like in plan view. Further, from the viewpoint of operability, it is possible to obtain an effect of preventing finger slipping when the cap cover 30 is rotated by making the outer peripheral surface have such an uneven shape.

  The cap cover 30 has an upper opening edge 31 extending to a position above the closed lid 20, and the upper edge of the lid 20 from the extended opening edges 31 a and 31 a. A pair of lid pressing pieces 32, 32 are extended toward the front.

  In addition, the cap cover 30 is located at a position where the lid 20 can be opened and closed (position shown in FIG. 1; hereinafter, also referred to as an “open / close position”). A front opening recess 33 is formed by recessing the opening edge 31 downwardly on the peripheral side surface, and the opening edge 31 is recessed downward on the peripheral side surface on the rear side facing the hinge portion 13 of the lid 20. A rear opening recess 34 is formed. The front opening recess 33 is formed in a substantially U shape, and the rear opening recess 34 is formed in a horizontally long rectangular shape that is recessed to a height at which the hinge portion 13 is exposed. Thus, at the opening / closing position of the lid 20, the front opening recess 33 is formed in the front circumferential surface facing the finger-hanging portion 21 of the lid 20, and the rear circumferential surface facing the hinge portion 13 of the lid 20. By forming the rear opening concave portion 34 in the opening / closing position, the finger hook portion 21 and the hinge portion 13 of the lid body 20 are exposed from the cap cover 30 at the opening / closing position, so that the lid body 20 can be smoothly opened and closed. .

  Further, by providing the front opening recess 33 and the rear opening recess 34 in this way, the opening edge 31a (31) in which the cap cover 30 is extended is substantially the opening edge 33 which is also an opening edge. The cap cover 30 is provided at two symmetrical positions excluding the rear opening recess 34, and a pair of lid pressing members from the opening edge portions 31a and 31a at the two locations toward the upper portion of the lid body 20. The pieces 32 and 32 are respectively extended. The lid pressing piece 32 is formed in a bow shape in plan view, and the opposite edges 32a and 32a are linear in the front-rear direction.

  The lid pressing piece 32 is provided at a position that completely overlaps the upper surface 10b of the cap body 10 located on both sides of the lid housing recess 12 in the open / close position (see also FIG. 1C). That is, at the open / close position, the edge 32a of the lid pressing piece 32 substantially coincides with the edge of the lid housing recess 12 in plan view, and faces the side wall portion 22 of the lid 20 in plan view. The upper part of the lid 20 does not overlap.

  As a result, the shape of the opening formed by the edges 32a, 32a of the pair of lid pressing pieces 32, 32 and the front opening recess 33 (31) in plan view is different from that of the finger hooking portion 21 of the lid 20 The side wall portions 22, 22 are substantially the same as the shape in plan view.

  That is, when attention is paid to the lid holding piece 32, the lid holding piece 32 is in a position that does not overlap the upper portion of the lid 20 at the open / close position, and the cap cover 30 is rotated from the open / close position to thereby close the lid body. The presser piece 32 also rotates in the same direction and moves to a position where the upper portion of the lid 20 overlaps.

  According to this configuration, the lid 20 can be opened and closed at a position where the shape of the opening of the cap cover 30 matches the shape of the lid 20. On the other hand, when the cap cover 30 is slightly rotated in either the right or left direction from this open / close position, the shape of the opening of the cap cover 30 is shifted in the rotational direction with respect to the shape of the lid 20. That is, with this rotation, the lid pressing piece 32 moves to the upper part of the lid 20 and presses the lid 20 from the upper part, thereby reliably preventing the lid 20 from being opened. That is, the closed lid 20 can be reliably locked. In this case, even if the cap cover 30 is rotated a little, the shape of the opening of the cap cover 30 is shifted in the rotation direction with respect to the shape of the lid 20, so that the corner of the lid 20 is covered with the lid of the cap cover 30. The presser piece 32 can be pressed. That is, it is possible to lock the closed lid 20 by slightly rotating the cap cover 30.

  On the other hand, a lower bottom surface of the cap cover 30 is opened, and a protrusion 35 that fits and slides into a groove 15 formed in the outer periphery of the cap body 10 is formed on the inner periphery thereof. The number of the protrusions 35 to be formed is not particularly limited, but it is preferable that the protrusions 35 are provided at a plurality of locations in the circumferential direction along the groove 15. In this embodiment, it is provided at two symmetrical positions. By providing the protrusions 35 at a plurality of locations, the cap cover 30 can be rotated more smoothly. The protrusion 35 is a portion related to the groove 15 and the first rib piece 16 of the cap body 10 and is not a portion directly related to the lid lock function for restricting the opening and closing of the lid 20, and therefore a click mechanism described later. It will be described in detail in the description of.

(3) Description of Lid Lock Function The cap 1 with lid lock function according to the embodiment is integrally formed by assembling the members having the above-described configuration. That is, the cap cover 30 is externally fitted to the cap body 10 to which the lid 20 is attached, and the protrusion 35 formed on the inner peripheral portion of the cap cover 30 is fitted in the groove portion 15 formed on the outer peripheral portion of the cap cover 30. The cap cover 30 is mounted so as to be rotatable in the circumferential direction along the outer peripheral portion of the cap body 10 without being detached from the cap body 10. FIG. 4 is a schematic plan view when the cap cover 30 is in the open / close position. FIGS. 5 to 9 show the cap cover 30 in the clockwise direction with respect to the open / close position shown in FIG. It is a schematic top view which shows the positional relationship of the cover body 20 and the cover body pressing piece 32 when it rotates each 90 degree | times, 135 degree | times, and 165 degree | times.

  As shown in FIG. 4, in the open / closed position where the front opening concave portion 33 of the cap cover 30 faces the finger-hanging portion 21 of the lid body 20, the lid body pressing piece 32 is in a position that does not overlap the lid body 20. 20 can be freely opened and closed. In this case, as shown in FIG. 4, the rear opening recess 34 is formed with a width W1 that is sufficiently wider than the width W2 of the hinge portion 13. Thus, even if the user inadvertently rotates the cap cover 30 with the lid 20 opened by making the width W1 of the rear opening recess 34 sufficiently wider than the width W2 of the hinge portion 13, the rear side The left and right edge portions of the opening recess 34 do not hit the hinge portion 13 immediately, and there is a slight margin until it hits, so that the hinge portion 13 can be used against an unexpected situation such as rotating the lid 20 open. It is possible to reduce damage even a little.

  On the other hand, when the cap cover 30 is rotated in either the right or left direction from the open / closed position shown in FIG. 4, the lid holding piece 32 is positioned above the lid 20 even if the rotation is slight. Thus, the opening operation of the lid 20 can be suppressed, and the lid 20 can be locked so as not to open unexpectedly.

  More specifically, when the cap cover 30 is rotated 15 degrees in the right direction R1, for example, from the open / closed position shown in FIG. 4, the lid pressing piece 32 also rotates in the same direction as shown in FIG. Will overlap the top of the lid 20. That is, in this case, the right lid pressing piece 32 slightly overlaps the right front corner portion of the lid 20 (the right side portion of the finger hook portion 21), and the left lid pressing piece 32 is left of the lid 20. The lid 20 is slightly overlapped with the rear corner portion, and the lid 20 is pressed by the lid pressing pieces 32 and 32 at these two overlapping portions (in FIG. 5, the overlapping portion is indicated by a broken line). And the lid 20 is locked so as not to open unexpectedly.

  Further, when the cap cover 30 is further rotated and rotated 45 degrees in the right direction R1 from the open / closed position shown in FIG. 4, the lid pressing piece 32 is further rotated in the same direction as shown in FIG. Will overlap the top of the lid 20. That is, in this case, the lower right lid pressing piece 32 overlaps with the right front corner portion of the lid 20 (the right side portion of the finger hook portion 21) over a wide area, and the upper left lid pressing piece 32 is the lid 20. The lid body 20 overlaps with the left rear corner of the lid body 20 in a wide area, and the lid body 20 has the lid body pressing pieces 32, 32 at these two overlapping portions (in FIG. 6, the overlapping portion is indicated by a broken line). And the lid 20 is securely locked so that it does not open unexpectedly.

  Further, when the cap cover 30 is further rotated and rotated 90 degrees in the right direction R1 from the open / closed position shown in FIG. 4, the lid pressing piece 32 is further rotated in the same direction as shown in FIG. The entire portion 32 a overlaps the upper portion of the lid 20. That is, in this case, almost the entire lower lid pressing piece 32 overlaps with the entire finger-holding portion 21 that is the front portion of the lid 20, and almost the entire upper lid pressing piece 32 of the lid 20. The lid 20 overlaps with the entire rear portion including the hinge portion 13, and the lid 20 is overlapped at two upper and lower (front and rear) overlapping portions (in FIG. 7, the overlapping portions are indicated by broken lines). The presser pieces 32 and 32 are surely pressed, and the lid 20 is securely locked so that it does not open unexpectedly.

  Further, when the cap cover 30 is further rotated and rotated 135 degrees in the right direction R1 from the open / closed position shown in FIG. 4, the lid pressing piece 32 is further rotated in the same direction as shown in FIG. Will overlap the top of the lid 20. That is, in this case, the upper right lid holding piece 32 overlaps with the right rear corner portion (the portion where the hinge portion 13 is provided) of the lid 20 over a wide area, and the lower left lid holding piece 32 is formed. The lid 20 overlaps with the left front corner portion (left side portion of the finger hook portion 21) of the lid body 20 in a wide area, and the lid body 20 has these two overlapping portions (in FIG. 8, the overlapping portion is indicated by a broken line). In this case, the lid body is securely pressed by the lid body pressing pieces 32 and 32 and is securely locked so that the lid body 20 is not opened unexpectedly.

  Further, when the cap cover 30 is further rotated and rotated 165 degrees in the right direction R1 from the opening / closing position shown in FIG. 4, the lid pressing piece 32 is further rotated in the same direction as shown in FIG. Will overlap the top of the lid 20. That is, in this case, the right lid pressing piece 32 slightly overlaps the right rear corner portion of the lid 20 (the portion where the hinge portion 13 is provided), and the left lid pressing piece 32 is the lid. The lid 20 is slightly overlapped with the left front corner portion of the body 20, and the lid 20 has the lid holding pieces 32 at these two overlapping portions (in FIG. 9, the overlapping portions are indicated by broken lines). , 32 and the lid 20 is locked so as not to open unexpectedly.

  In the description of the lid lock function, the case where the cap cover 30 is rotated in the right direction R1 has been described. However, the same applies to the case where the cap cover 30 is rotated in the left direction R2. Further, in the explanation of the lid lock function, for easy understanding, the lock state when the cap cover 30 is rotated to a certain angle such as 15 degrees, 45 degrees, 90 degrees, etc. will be described. ing. However, as is clear from the above description, the cap 1 with the lid locking function of the present embodiment moves the lid pressing piece 32 to the upper portion of the lid 20 when the cap cover 30 is slightly rotated from the open / close position. Thus, the lid 20 is locked. That is, the lid 20 can be reliably locked regardless of the position of the cap cover 30 that is rotated except the open / close position.

  In order to realize such a lid locking function, the shape of the lid body 20 is important as described above. When the lid body 20 is circular, the lid body 20 is locked at a position other than the opening / closing position. It is not possible. Therefore, in the present embodiment, the lid 20 has a front-side finger-hanging portion 21 in an arc shape, and the left and right side wall portions 22 and 22 that follow the arc-shaped shape. And the edge part 32a of the cover body pressing piece 32 corresponding to this is also a linear shape so that it may confront the side wall part 22 by planar view. However, such a shape is an example, and in the present invention, any shape can be used as long as the shape of the lid 20 in a plan view is a shape other than a circular shape. Hereinafter, specific examples of other shapes of the lid body 20 and the lid body pressing piece 32 will be described with an example.

(Specific example 1 of other shapes of the lid 20 and the lid pressing piece 32)
FIG. 10 is a plan view showing a specific example 1 of another shape of the lid body 20 and the lid body pressing piece 32.

  In the first specific example, the lid 20 has an elliptical shape that is long in the front-rear direction and does not include a straight line portion on the left and right side walls 22, 22 (however, the rear side is straight due to the provision of the hinge portion 13). The lid pressing piece 32 provided on the cap cover 30 is also curved so that the edge 32a faces the curved side wall 22 of the lid 20 in plan view. As a whole, it has a crescent shape. Even in such a configuration, the lid 20 can be reliably locked regardless of the position where the cap cover 30 is rotated except in the open / close position.

(Specific example 2 of other shapes of the lid 20 and the lid pressing piece 32)
FIG. 11 is a plan view showing a specific example 2 of another shape of the lid body 20 and the lid body pressing piece 32.

  In the above-described embodiment and specific example 1, the lid 20 has a bilaterally symmetric shape, but in specific example 2, the design of the lid 20 is deliberately asymmetrical in consideration of design and the like. .

  That is, in the specific example 2, only the right side wall part 22 of the lid 20 is linear, and the left side wall part 22a is circular. That is, the entire finger-hanging portion 21 and the left side wall portion 22a have an arc shape. Therefore, in the second specific example, the lid pressing piece 32 provided on the cap cover 30 is only one place on the right side facing the right side wall part 22 that is a straight line. In this case, when the cap cover 30 is rotated, there is only one position where the lid pressing piece 32 overlaps the upper portion of the lid 20. Even in this case, the lid 20 is pressed by the lid pressing piece 32. Since there is no change, the lid 20 is locked so as not to open unexpectedly.

  As can be seen from the specific examples 1 and 2, in the cap 1 with a lid locking function of the present invention, the lid 20 has any shape other than a circular shape (except for a shape very close to a circle, etc.). Even if it is a shape, it is characterized in that it can have a locking function.

  In the specific example 1, both the side wall portion 22 of the lid body 20 and the edge portion 32a of the lid body pressing piece 32 opposed thereto are curved, and in the specific example 2, the side wall portion 22 of the lid body 20 is formed. Although the case where both of the edge portions 32a of the lid pressing piece 32 opposed thereto are straight lines is illustrated, it is not limited to such a curve or a pattern of straight lines. For example, the side wall 22 of the lid 20 is a straight line, and the edge 32a of the lid pressing piece 32 facing the straight line is a curved pattern, and the side wall 22 of the lid 20 is curved and the lid pressing the opposite side. Various combinations of patterns, such as a pattern in which the edge portion 32a of the piece 32 is a straight line, can be employed. According to the present invention, the lid 20 can be directly locked by the lid pressing piece 32 by rotating the cap cover 30 in any combination pattern as long as the rotation angle to be locked is not concerned. Is possible.

  Moreover, in the said embodiment and the specific examples 1 and 2, although the number (namely, location provided) of the cover body pressing piece 32 is two places of the left-right symmetrical position, or one place of the left or right, Three or more places may be provided. That is, the lid pressing piece 32 may be further divided into smaller parts and distributed around the cap cover 30. How to arrange may be determined as appropriate in consideration of the shape of the lid 20.

On the other hand, for the user, it is convenient in terms of operability that the lid lock function works regardless of the position, but on the other hand, the lid 20 is securely locked by rotating the cap cover 30. If it can be confirmed by some kind of touch or feeling, it is safe. Therefore, in the present embodiment, the lid lock function is functioning reliably, that is, the lid body pressing piece 32 is at the upper part of the lid body 20 and is in a position that reliably regulates the opening of the lid body 20. In order to inform the user, a click function and a rotation lock function are provided. Hereinafter, the click function and the rotation lock function will be described.
(3) Description of Click Function and Rotation Lock Function As described above, the cap cover 30 has the protrusion 35 provided on the inner peripheral portion fitted in the groove portion 15 provided on the outer peripheral portion of the cap body 10. By sliding, the periphery of the cap body 10 is freely rotated.

  Therefore, in the embodiment, the first rib piece 16 is provided at an appropriate position of the groove portion 15 so that the projection portion 35 hits and gets over. The cap body 10 and the cap cover 30 are made of resin. Therefore, the cap cover 30 can be somewhat deformed by the elastic force of the resin itself, and the protrusion 35 can be configured to get over the first rib piece 16 by this elastic deformation force.

  FIG. 12 is a cross-sectional view along the groove 15 of the cap 1 with a lid locking function, and FIG. 13 is a cross-sectional view along the groove 15 in which the first rib piece 16 is partially enlarged.

  As shown in FIG. 13, a pair of first rib pieces 16 are provided at intervals of a little wider than the width of the protrusion 35 at each click position. As shown in FIG. 13, the pair of first rib pieces 16 a and 16 b are formed in a cross-sectional mountain shape along the rotation direction, and the height H1 is the height H2 of the protrusion 35 (that is, Lower than the depth of the groove 15. Thereby, the projection part 35 can get over the first rib piece 16 in the groove part 15. When the protruding portion 35 sandwiched between the first rib pieces 16a and 16b rotates in the left direction R1, a click feeling (due to the elastic deformation of the resin and the elastic return) is obtained when the left rib portion 16a is overcome. (Elasticity) is obtained, and when it rotates in the right direction R2, it is possible to obtain a click feeling when getting over the first rib piece 16b on the right side. In addition, by providing a pair of first rib pieces 16 at each click position, when the projection 35 is fitted between the first rib pieces 16a and 16b, a feeling of being stopped at that position (lock feeling) is obtained. Can do.

  According to this configuration, when the cap cover 30 is rotated, a click feeling (and a lock feeling) is transmitted to the operator's hand by the protrusion 35 getting over the first rib pieces 16a and 16b, so that the position is surely reached. It is possible to feel that it has been rotated (ie, confirmed by touch). Therefore, the cap cover 30 is formed by forming such a pair of first rib pieces 16a and 16b in the groove portion 15 at intervals of, for example, every 15 degrees, every 30 degrees, every 45 degrees, and the like. It becomes easy to rotate in a stepwise manner to a predetermined angle.

  In addition, in FIG. 12, the case where a pair of 1st rib piece 16a, 16b is formed every 45 degree | times is illustrated. Therefore, in this case, when the cap cover 30 rotates to the open / close position shown in FIG. 4, rotates to the 45 degree position shown in FIGS. 6 and 8, and rotates to the 90 degree position shown in FIG. When you do this, you will get a click feeling.

  In the above description, the case where the cap cover 30 can freely rotate around the cap body 10 by 360 degrees is described as an example. However, the rotation angle of the cap cover 30 is restricted to 90 degrees, for example. May be. In other words, it may be configured such that when it is rotated to a position where it is reliably locked, the rotation is restricted there and no further rotation is performed.

  FIG. 14 illustrates a case where the rotation angle of the cap cover 30 is restricted to 90 degrees.

  In this case, the groove portion 15 is not the entire circumference of the outer peripheral portion of the cap body 10, but the pair of first rib pieces 16a and 16b provided on the left and right sides of the cap body 10 as the center. Each of R2 is formed up to an angle of 45 degrees (that is, a range of a rotation angle of 90 degrees as a whole). And in the end part of the groove part 15 formed in this way, the end wall 15a of the groove part 15 and the one first rib piece 16c opposite to the same function as the pair of first rib pieces 16a and 16b. Plays.

  That is, in this case, when the protrusion 35 fitted between the end wall 15a and the first rib piece 16c gets over the first rib piece 16c toward the end wall 15a on the opposite side of the groove 15. When the protrusion 35 in the groove 15 gets over the first rib piece 16c toward the end wall 15a, the click is locked and the further rotation is restricted against the end wall 15a. A feeling can be obtained. Therefore, in this case, the end wall 15a of the groove portion 15 functions as a second rib piece for restricting the rotational movement of the projection portion described in the claims.

  That is, in the example shown in FIG. 14, a click feeling is obtained when the cap cover 30 is rotated to the open / close position shown in FIG. 1, and when the cap cover 30 is rotated to a 45 degree position shown in FIGS. A feeling will be obtained.

  According to this configuration, after the user closes the lid 20, the user only needs to rotate the cap cover 30 in one direction from the opening / closing position to the position where the rotation stops, and whether or not the lid 20 is locked. It is not necessary to confirm each by visual inspection.

  In addition, 90 degrees of the rotation angle to restrict | regulate is an example to the last, For example, it is possible to set freely, such as 30 degree | times, 60 degree | times, 120 degree | times, 150 degree | times. Further, in the above rotation angle restriction, the cap cover 30 is described as being rotatable in both the left direction R1 and the right direction R2 from the open / close position, but either the left direction R1 or the right direction R2 from the open / close position. For example, it may be configured to be rotatable only by 45 degrees.

  Further, in FIG. 14, the groove portion 15 is formed in a part of the outer peripheral portion of the cap body 10 to restrict the rotation angle of the cap cover 30, but the groove portion 15 itself is the entire periphery of the outer peripheral portion of the cap body 10. The second rib piece that is taller than the first rib piece 16c (that is, the height reaching the outer peripheral surface of the cap body 10) is formed at a location corresponding to the end portion 15a of the groove portion 15. Thus, the configuration may be such that the rotation angle of the cap cover 30 is regulated.

(4) Description of Wearability of Cap 1 with Lid Lock Function In the cap 1 with lid lock function of the present embodiment, the wearability when the cap cover 30 is attached to the cap body 10 is also considered.

  15 is a cross-sectional view taken along line BB in FIG. 2A.

  As shown in FIGS. 2A and 15, the upper end of the opening edge portion 31 a is located on the cap body 10 at the outer peripheral portion where the groove portion 15 is formed and corresponding to the projection portion 35 formed on the cap cover 30. A vertical groove 17 reaching the groove portion 15 from the portion is formed. In addition, a third rib piece 18 is formed in the vertical groove 17 at a position directly above the groove portion 15 so that the projection 35 slides downward in the vertical groove 17 and rides over the groove portion 15 side. The third rib piece 18 is configured such that the projection 35 fitted in the groove 15 does not return to the vertical groove 17 side again. Specifically, the third rib piece 18 is formed on an inclined surface 18a that spreads outward from the opening edge 31a side toward the groove portion 15 side, and a lower surface 18b that continues from the lower end portion of the inclined surface 18a becomes a horizontal plane. ing. That is, even if the projection 35 that has passed over the third rib piece 18 and fitted into the groove 15 is rotated to the position facing the vertical groove 17 by rotation in the circumferential direction in the groove 15, the lower portion of the vertical groove 17 Is closed by the horizontal surface (lower surface) 18b of the third rib piece 18, and the upward movement of the protrusion 35 is restricted by the horizontal surface 18b. Thereby, the mounting property when the cap cover 30 is mounted on the cap body 10 is improved, and a mounting structure that does not easily come off after the cap cover 30 is once mounted can be obtained.

  In the above embodiment, the groove portion 15 is provided on the outer peripheral portion of the cap body 10 and the projection portion 35 is provided on the inner peripheral portion of the cap cover 30. On the contrary, the groove portion 15 is provided on the inner side of the cap cover 30. The protrusion 35 may be provided on the outer periphery of the cap cover 30.

  The present invention can be implemented in various other forms without departing from the spirit or main features thereof. Therefore, the above-mentioned embodiment is only a mere illustration in all points, and should not be interpreted limitedly. The scope of the present invention is set forth in the claims, and is not restricted by the text of the specification. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.
