Description

  The present invention relates to a lid lock structure that can prevent the lid from opening unexpectedly while the lid opening operation is simple, and more particularly to various containers such as a portable thermos The present invention relates to a lid lock structure suitable for being provided in a beverage container.

  As a locking device that prevents the lid from accidentally opening, there is one disclosed in Patent Document 1 below.

  This locking device is such that the lock is released when a force acting in a different direction is applied to the stop element and another lid, and simultaneously pressing the stop element, When the lid engaged with this is moved in a direction different from the pressing direction of the stop element, the lock is released and the lid is opened.

  If the operation | movement for unlocking is shown concretely, while putting a fingertip between a stop element and a cover body and pressing a cover body with the fingertip, the operation | movement is simple.

  However, in such a configuration, if some projection enters between the stop element and the lid and a force that squeezes the lid acts on the projection, the lock is released.

  For this reason, when the said structure is employ | adopted with respect to what has an opportunity which contacts other articles | goods, such as the inside of a bag or a backpack, for example, a cover body may open unexpectedly.

  On the other hand, in beverage containers that are often carried in bags or rucksacks, etc., and having a drinking mouth with a mouth directly attached to drink inside beverages, the lid is accidentally In order to prevent the opening, a lock structure as disclosed in the following Patent Document 2 has been proposed.

  In other words, the lock structure for the beverage container plug body of Patent Document 2 has an engaging portion that can be engaged with and disengaged from an engaging piece provided at the rotating end of the lid member at the top, and the engaging portion is locked. A lock button having a biasing means for biasing in the direction of engagement with the piece, and movement of the lock button in the unlocking direction when inserted between the lower portion of the lock button and the outer peripheral wall of the plug member In addition, it has a slide type stopper that allows the lock button to move in the unlocking direction when it is slid downward and positioned at the non-insertion position. In other words, the lock can be performed when the slide type stopper is positioned inside the lock button, and the lock is released when the slide type stopper is removed from the inside of the lock button.

  According to such a configuration, the lid member can be opened when the slide stopper is pushed down with the fingertip and then the lower part of the lock button is pushed with the finger or another finger.

  However, as described above, the operation of moving the slide stopper up and down and the operation of pressing the lock button cannot be performed as a series of operations. That is, when the lid member is opened, two completely different operations must be performed, and the ease of operation is lacking. For this reason, it is difficult to quickly open with one hand.

  Further, in the configuration of Patent Document 2, a gap is formed between the lock button and the sliding stopper when the sliding stopper is lowered. For this reason, after drinking a beverage, if it is left on the ground without raising the sliding stopper, foreign matter may enter, and if the sliding stopper is operated without knowing it, the operation will be hindered. It will be.

  Furthermore, in the configuration of Patent Document 2, since the slide stopper prevents the lock button from moving at the insertion position, the lock button does not move when the slide stopper is at the insertion position. For this reason, when the lid member is opened and the sliding stopper is mistakenly raised to the insertion position and the lid is to be closed, the lock button and the shaft portion pivotally supporting the lock button are arranged. There is a risk of damage due to excessive load.

  Therefore, the main object of the present invention is to provide a lid lock structure that does not open unexpectedly even when it comes into contact with other articles and that can be opened very easily with one touch.

Means therefor is a lid lock structure for holding a lid pivotally mounted on the main body portion in a closed state by locking with a locking claw of a locking member pivotally mounted on the main body portion. A sliding lock member that slides in the length direction along the locking member inside the locking member, and a biasing means that biases the sliding lock member and / or the locking member toward the outside The sliding lock member includes an operating portion that protrudes to a position outside the outer surface of the locking member, and the locking member is locked when the operating portion is pressed inward and rotated. A rotational force transmitting portion that rotates in the direction in which the pawl is unlocked, and a part of the main body member when the sliding lock member is slid to one side in the length direction of the locking member. contact with or close to the rotation regulating portion for preventing the rotation of the slide lock member is formed Rutotomoni, the sliding Locking member relative to the shank for pivotally said locking member is a lid lock structure which is attached via a long hole.

  The rotational force transmitting portion and the rotational restricting portion transmit rotational force or prevent rotation in a relative relationship with opposing members, and are not only formed in a special shape / structure, It includes those formed in a plate shape or a planar shape.

  In the above configuration, when the lid is opened, the operating portion of the sliding lock member is slid to one side in the length direction of the locking member with the fingertip and moved to the unlocking position, or after sliding. However, it may be pressed toward the inside. That is, by sliding the sliding lock member, the rotation restricting portion is not in contact with or close to a part of the main body member, and the rotation by the pressing is allowed. Since it is pressed and rotated in this state, the rotational force is transmitted to the locking member via the rotational force transmitting portion. As a result, the latching claw of the latching member comes off from the lid, so that the lid can be opened.

  On the other hand, in order to lock the lid so that it does not open unexpectedly, the sliding lock member may be slid to the other side and moved to the lock position with the lid closed. The rotation restricting portion of the sliding lock member comes into contact with or close to a part of the main body member, and the rotation of the sliding lock member and the locking member becomes impossible.

Here, about each said component, it can comprise in the following aspects, for example .

One aspect is the rotation restricting portion is formed in a part of the width direction of the locking member is a protrusion that protrudes inward.
That is, since the rotation restricting portion is a protrusion formed in a part of the locking member in the width direction, the urging means for urging the sliding lock member and / or the locking member is, for example, a rotation restricting portion. They can be provided at positions close to each other. For this reason, the lock structure can be made compact.

  In the above case, a convex portion or a concave portion facing the rotation restricting portion may be formed on the surface of the main body portion facing the sliding lock member. That is, it is a convex part with which the rotation restricting part comes into contact or close when performing rotation restriction, or a concave part with which the rotation restricting part comes into contact with or approaches when rotation restriction is not performed.

In another aspect, the locking member is independent on the inside of the contact portion with the sliding lock member below the pivoting portion of the locking member in a direction in which the locking member releases the locking claw. In order to be displaceable, a space is formed.
In other words, even if the sliding lock member is in the locked position where the locking member is prevented from rotating, the locking member can be operated when the lid is unexpectedly closed and the latching claw receives a load from the lid. Since the lower side than the pivot attachment part is displaced to the space part side, the lid can be allowed to be closed. For this reason, the inconvenience that the lock structure is damaged can be avoided.

In another aspect, a thin recess is formed on the upper surface of the lid on the pivotal attachment side so as to avoid collision with the hand holding the main body when the lid is opened.
In other words, when the lid is opened using the lock structure, even if the lid is opened vigorously, the lid does not hit the hand holding the main body due to the presence of the relief recess, and the operation is performed with peace of mind. be able to.

  As described above, according to the present invention, the lid can be opened by a series of operations that can be performed with one hand, that is, sliding and pressing the sliding lock member. For this reason, it is possible to open the lid very easily with one touch.

Moreover, since the direction of the series of operations is different, even if the sliding lock member comes into contact with another article in the locked state, the lid body does not open unexpectedly under the influence of the lock structure. Assuredly achieve the intended purpose. Further, since the shaft portion for pivotally attaching the locking member can also be used for mounting the sliding lock member, the number of parts can be reduced and the assembling work can be facilitated.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a vertical cross-sectional view (a cross-sectional view taken along the line AA in FIG. 2) of the upper portion of the beverage container 11. As shown in this figure, the beverage container 11 is opened with the lid 12 at the upper end by one touch. It is configured as follows.

  That is, it has the container main body 13 for putting the beverage container 11, the base member 14 that is detachably attached to the upper part of the container main body 13, and the lid body 12 pivotally mounted on the base member 14. The mouthpiece member 14 is provided with a drinking mouth 15 for directly drinking a drink inside, so that the convenience of opening with one touch can be enjoyed.

  The lid body 12 has a substantially inverted bowl shape that hides the drinking mouth 15, and a sealing material 16 that seals the upper end opening of the drinking mouth 15 is attached to the portion corresponding to the drinking mouth 15 on the inner ceiling surface. It has been. As shown in FIG. 3, the lid body 12 is pivotally attached to the pivoting portion 17 on the rear side of the cap member 14 via a cylindrical shaft member 18 and a torsion coil spring 19. That is, the lid 12 is always urged in the opening direction by the torsion coil spring 19.

  The torsion coil spring 19 is housed in a spring housing space 20 formed on the side surface of the pivoting portion 17 of the base member 14 and attached so as not to be seen from the outside. The spring accommodating space 20 may be provided on the lid 12 side.

  The lid locking mechanism 21 holds the lid 12 closed against the urging force of the torsion coil spring 19, and the pivot portion 17 extends over the base member 14 and the lid 12. It is formed on the opposite side.

  The lid locking mechanism 21 locks the locking claw 32 at the upper end of the locking member 31 pivotally attached to the base member 14 with respect to the locked portion 12 a formed on the lid 12. The lid 12 is held in a closed state. In order to prevent an accidental rotation of the locking member 31 and to enable a simple opening operation, the rotation of the locking member 31 is restricted. A sliding lock member 41 is provided. The locking member 31 and the sliding lock member 41 are accommodated in a recess 51 formed in the base member 15. The recess 51 has a substantially vertically long rectangular shape when viewed from the front, and is formed with an outer wall 52 raised in a bank shape around the recess 51.

  The locking member 31 is rotatably mounted in the recess 51, and is stepped from the outer surface portion 33 having a plate shape having a width corresponding to the width dimension of the recess, and the lower portion on the inner surface of the outer surface portion 33. The extended portion 34 is extended and narrower than the outer surface portion 33. The pivoting pieces 35, 35 for attachment are formed on the inner side surface in the intermediate portion in the longitudinal direction of the outer surface portion 33, and the locking claw 32 is formed on the upper end of the outer surface portion 33. The upper inclined surface of the locking claw 32 is a driven surface 32a for rotating the locking member 31 when the lid 12 is closed.

  In addition, a positioning protrusion that holds one end of the spring 61 is formed on the inner side surface of the extended portion 34 as an urging means for urging the sliding lock member 41 and the locking member 31 outward. ing.

  On the other hand, a positioning projection 53 that holds the other end of the spring 61 is formed at a portion of the recess 51 that faces the positioning projection 36.

  The sliding lock member 41 slides in the length direction along the locking member 31, and is formed to have a width corresponding to the width dimension of the recess 51 and is located at the lower end, It has two sliding piece parts 43, 43 extending upward from the left and right sides of the operation part 42. As shown in FIGS. 4 and 5, these two sliding piece portions 43 are located on the outside so as to sandwich the two pivoting pieces 35, 35.

  The operation portion 42 is positioned so as to cover the outer surface of the extending portion 34 and the left and right sides of the locking member 31 and is formed in a gate shape. The inner side surface of the intermediate portion in the left-right direction is a sliding surface 44 that slides on the outer side surface of the extending portion 34. As a result of forming the operation portion 42 in a gate shape, a space portion 54 that can accommodate the spring 61 is formed inside the extended portion 34 of the locking member 31 located below the operation portion 42. Since this space portion 54 is provided, there is nothing that prevents the extended portion 34 of the locking member 31 from being displaced inward, and the sliding lock member 41 is in the unlocked position when it is in the locked position. Regardless, the extension 34 can be displaced inward.

  Further, rotation restricting protrusions 45 as rotation restricting portions that prevent the rotation of the sliding lock member 41 are formed on inner side surfaces of both end portions in the left-right direction of the operation portion 42. The rotation restricting projection 45 prevents the rotation of the sliding lock member 41 when the sliding lock member 41 is slid upward and positioned at the lock position. Correspondingly, on the inner surface of the recess 51, there is a locking protrusion 55 with which the tip surface of the rotation restricting protrusion 45 abuts or approaches when the sliding lock member 41 is slid upward. Is formed.

  The outer surface of the sliding piece 43 that faces the locking member 31 is a sliding surface 46 that slides on the inner surface of the locking member 31. And the upper end part of each sliding piece part 43 is formed large in the inside and outside direction, and the attaching part 47 for attaching so that sliding and rotation are possible is provided. The attachment portion 47 is formed with a long hole 48 extending in the vertical direction through which the pin member 62 pivotally attached to the locking member 31 is formed. The recess 51 is integrated with the locking member 31. Allowing them to be combined and installed.

  The long hole 48 is provided with a structure for providing moderation when the pin member 62 is positioned at both ends thereof. When moderation is given, a click feeling is obtained during operation, the feel when operated is good, and the sliding lock member can be held in its upward movement position (lock position) and downward movement position (lock release position). The configuration can be obtained by setting the diameter of both end portions 48a of the long hole 48 to be smaller than the diameter of the intermediate portion 48b, as shown in FIG. Further, as shown in FIG. 6B, it may be due to the protrusion 48c that holds the pin member 62 in the both end portions 48a. In addition to the above, the structure for obtaining the moderation can be formed in various forms at appropriate portions where the locking member 31 and the sliding lock member 41 are opposed to each other. In addition to providing moderation, it can also be formed to stop at contact resistance.

  The sliding surfaces 44 and 46 are configured so that when the operation portion 42 of the sliding lock member 41 is pressed inward and rotated, the locking member 31 is moved in a direction in which the locking claw 32 is unlocked. It is a rotational force transmission part to rotate.

Further, in the lid body 12 having the lid body locking mechanism 21, the upper surface of the pivot mounting portion 17 side avoids a collision with a hand holding the base member 14 when the lid is opened as shown in FIG. A relief recess 12b is formed. The thin recess 12b is formed by drawing an arc so as to go around the corner of the lid 12.
Furthermore, 12c in the figure is a decorative member for making the appearance beautiful.

  In the beverage container 11 provided with the lid lock mechanism 21 having the above-described configuration, the lid 12 is opened as follows.

  That is, when the operating portion 42 of the sliding lock member 41 is slid downward from the locked state shown by the solid line in FIG. 1, the sliding lock member 41 is lowered to the lowest position. Stops at the release position. When the sliding lock member 41 is pressed inward in this state, the two sliding surfaces 44 and 46 of the sliding lock member 41 rotate the locking member 31 against the urging force of the spring 61, The locking claw 32 of the member 31 is removed from the locked portion 12 a of the lid body 12. Then, the lid body 12 urged by the torsion coil spring 19 is quickly opened as shown in FIG. 7 by the urging force, and the upper end portion of the drinking mouth 15 is opened, so that the beverage can be drunk immediately. When the lid 12 is opened, the hand 71 is located at the position shown by the phantom line in FIG. 7, but the lid 12 hits the hand 71 because the cover 12 is formed with the thin recess 12b. There is no such thing and the lid 12 can be opened with peace of mind.

  To close the lid body 12, the lid body 12 is rotated and pushed down against the biasing force of the torsion coil spring 19. Due to the presence of the driven surface 32 a formed on the upper surface of the locking claw 32, the locking member 31 is rotated and is automatically locked.

  Even if the sliding lock member 41 is slid upward and is positioned at the locked position, the lower portion of the locking member 31 is positioned inside the sliding lock member 41, and there is a space inside Since the portion 54 is formed, if the lid 12 is to be closed, the locking member 31 is passively displaced in the direction of releasing the locking claw 32 and receives the lid 12. For this reason, inconveniences such as accidental damage do not occur.

  After the lid 12 is closed, when the sliding lock member 41 is raised and positioned at the lock position, the rotation restricting projection 45 of the sliding lock member 41 is formed into the locking projection 55 formed in the recess 51. The sliding lock member 41 and the locking member 31 are prevented from rotating in contact with or close to each other. For this reason, it can prevent that the cover body 12 opens unexpectedly.

  As described above, when the sliding lock member 41 is slid, the contact or proximity state between the rotation restricting projection 45 and the locking projection 55 is released. If it pushes toward, the locking member 31 will rotate with the sliding lock member 41, and the cover body 12 will open instantly with urging | biasing force.

  That is, the operation to push down the sliding lock member 41 and the operation to push it inward can be easily performed with one hand as a series. For this reason, opening operation is very simple, and it becomes the drink container 11 which can be drunk immediately when it wants to drink.

  In addition, since the series of operations are performed in different directions, even if the sliding lock member comes into contact with other articles in the locked state, the lid body does not open unexpectedly due to the influence, and the locking is ensured. Can be. For this reason, for example, when the beverage container 11 is carried around in a bag or a rucksack or the like, even if the sliding lock member 41 comes into contact with any article, a state in which the lid 12 does not open unexpectedly is obtained. It is done.

  In addition, the sliding lock member 41 that slides in the vertical direction always exists inside the locking member 31, and there is no gap between the locking member 31 and the locking member 31. For this reason, it is possible to prevent inconveniences such as unexpected entry of foreign matter, which hinders operation or is damaged.

  Further, since the locking member 31 and the sliding lock member 41 are attached by the same pin member 62, the number of parts can be reduced and the assembling work can be easily performed.

  Further, since the rotation restricting protrusion 45 and the locking protrusion 55 and the spring as the biasing means are arranged side by side in the width direction of the recess 51, the lock mechanism 21 can be formed compactly.

  Furthermore, since the rotation restriction protrusion 45 and the lock protrusion 55 restrict the rotation, the spring 61 can be stored and the space portion 54 can be formed well, and the structure can be simplified.

The rotation restricting portion corresponds to the rotation restricting protrusion 45,
The convex portion facing the rotation restricting portion corresponds to the locking projection 55,
The present invention is not limited to the configuration of the above-described one form, and various other forms can be adopted.

  For example, it may be configured to be in the unlocked position when the sliding lock member 41 is slid upward, and to be in the locked position when it is slid downward. The unlocking operation after unlocking is simple because it is an operation that can be performed as a series of operations of pushing the sliding lock member 41 upward while pushing it upward.

  Further, the urging means may be formed integrally with the locking member 31 or the sliding lock member 41, for example, in the form of a leaf spring.

  Further, instead of the torsion coil spring 19, the lid 12 may be urged in the opening direction by a sealing material or other appropriate urging means, and the urging means may be omitted. .
