Description

  According to the present invention, the mouth of the container body is opened by pressing the push button of the operation unit provided at the upper part of the handle while holding the handle attached to the side surface of the container body, and the stored liquid is opened by tilting the container body. It is related with the liquid pot which came to pour from a part.

  This type of liquid pot is provided with an opening / closing interlocking mechanism on the container body side that converts the pushing operation of the operation portion into the opening / closing operation of the mouth portion. Conventionally, as an operation unit, a push button member that is pushed into the container body side with respect to an upper portion of the handle, a button insertion portion that guides the sliding movement of the push button member in the advance and retreat direction, and a push shaft member that advances and retreats integrally with the push button member A mechanism comprising a return spring interposed between the push shaft member and the container body while being passed through the push shaft member is used. When the push button member is pushed while the handle is held, the push shaft member protrudes from a shaft opening formed in the container body to move the opening / closing interlock mechanism.

  With this type of operation unit, when the handle is attached to the container body, the push shaft member through the return spring is inserted from the front end side into the shaft outlet of the container body, and the push button member is pushed into the button compartment. The button member is prevented from coming off by engagement with the button insertion portion. The inner periphery of the shaft outlet supports the container body side of the push shaft member, and the push button member supports the handle side of the push shaft member (Patent Document 1).

  The operation part of the above-mentioned patent document 1 picks the rear end side of the push shaft member, inserts it from the front end side into the shaft outlet of the container body, maintains the return spring in a compressed state, and pushes the push shaft member from the shaft outlet. When the projecting part is fixed, the retaining ring is fixed to the projecting part, and the hand is released, the pushing shaft member moves backward due to the elastic repulsion of the return spring, and the inner periphery of the retaining ring and the shaft outlet, and the outer periphery and the centering of the pushing shaft member. The push shaft member is centered by contact with the inner periphery of the mouth. The centering is set so as to regulate the eccentric amount of the rear end of the push shaft member so that the push button member can be aligned with the shaft support portion of the push button member when the push button member is pushed into the button insertion portion. . Further, the push shaft member is prevented from coming off by the wall portion in which the retaining ring and the shaft outlet are formed. When the push shaft member is temporarily fixed by the above-described retaining and centering, the attachment position of the push shaft member and the push button member can be aligned.

Japanese Examined Patent Publication No. 7-77574

  However, the push shaft member mounting structure as in Patent Document 1 described above is troublesome to attach the retaining ring while causing the push shaft member to protrude from the shaft outlet.

  In view of the above circumstances, an object of the present invention is to make it possible to easily temporarily fix a push shaft member of an operation portion provided on an upper portion of a handle.

  In order to solve the above-described problems, the present invention provides a handle attached to a side surface of a container body, an operation portion provided on an upper portion of the handle, and an opening / closing operation of a mouth portion of the container body by pushing the operation portion. An opening / closing interlocking mechanism for converting to the above, the operation unit, a push button member that pushes into the container body side with respect to the upper portion of the handle, a button insertion unit that guides the sliding movement of the push button member in the forward and backward direction, A push-shaft member that advances and retreats integrally with the push-button member; and a return spring that is interposed between the push-shaft member and the container body while being passed through the push-shaft member. The opening / closing interlock mechanism is moved by protruding from the shaft outlet formed in the body, the inner periphery of the shaft outlet supports the container body side of the push shaft member, and the push button member moves the handle side of the push shaft member. Branch In the liquid pot in which the push button member is pushed in a state where the handle is held and the container body is tilted so that the stored liquid is poured from the mouth portion, the button holder is formed by the push shaft member. And a shaft installation opening for inserting the return spring between the shaft insertion opening and the shaft extraction opening, and the shaft insertion opening includes the push shaft member. The return spring is provided so as to be insertable, and a centering portion that partially contacts the inner periphery of the spring installation space is formed on the outer periphery of the push shaft member so as to protrude from the return spring. The mouth is formed with a notch portion through which the centering portion passes, and the centering portion is detached from the notch portion by rotating the push shaft member while being inserted into the spring installation space. Hang on the wall Ri, and adopt a configuration in which the push rod member is retained by the caught.

  According to the configuration of the present invention, the centering portion of the push shaft member and the notch of the shaft insertion port are aligned, and the return shaft is inserted into the shaft insertion port by inserting the push shaft member together with the return spring from the shaft insertion port. When the push shaft member is supported on the inner periphery of the shaft outlet at the same time as it is inserted into the spring installation space between the shaft outlets, and the push shaft member is rotated in this state, centering and retaining of the push shaft member can be obtained. . Thus, according to the present invention, the push shaft member can be temporarily fixed by a simple operation of inserting and rotating the push shaft member.

Each embodiment of the present invention will be described below.
The liquid pot according to the first embodiment (hereinafter simply abbreviated as “first embodiment”. The other embodiments are also abbreviated as follows) is a state where the push button member is attached to the button slot. The push shaft member is positioned by the push button member so that the centering portion does not retract the notch portion.

  After the push button member is attached as described above, the retracted position of the push shaft member can be limited by the push button member. When the push shaft member rotates for some reason during use and the position of the centering part and the notch part is aligned, the centering part moves backward with the notch part due to the retraction of the push shaft member that has been repelled by the return spring. Then, when the push shaft member rotates for some reason, the centering portion may be caught on the handle wall. In this state, the push button member cannot be pushed.

  In the first embodiment, since the push shaft member is positioned using the push button member so that the centering portion does not retract the notch portion, the push button is not added without adding a detent structure for the push shaft member. It is possible to reliably perform the pushing operation of the member.

  In addition, when a rotation prevention structure is provided, there exists an advantage which can set the retreat range of a centering part freely. If the anti-rotation structure is provided as an uneven structure at the front end of the push button member and the rear end of the push shaft member, the anti-rotation can be prevented only by attaching the push button member.

  In the second embodiment, the push shaft member is pushed by the push button member attached to the button insertion portion, and the centering portion is positioned away from the handle wall.

  In the second embodiment, when the push shaft member is positioned using the push button member as described above, the forming error and the assembly error are managed by the distance of the centering portion away from the handle wall on the forward side. It becomes easier and can absorb secular deformation.

  In the third embodiment, the front end of the centering portion is always positioned closer to the container body than the joint between the container body and the handle existing on the inner periphery of the spring installation space.

  Since a spring installation space for accommodating a return spring is formed between the shaft insertion port and the shaft output port, there is a seam between the handle and the container body on the inner periphery of the spring installation space. If an attempt is made to eliminate the joint, a spring installation space is formed on either the handle or the container body. Since the spring support is performed in the spring installation space, it is very difficult to mold one member, which is not practical.

  In the third embodiment, since the front end of the centering part is always positioned closer to the container body than the seam, the centering part may be caught in the seam when the push button member is pressed. There is no.

  In the fourth embodiment, the centering portion is a spring receiver that holds the rear end of the return spring.

  In the fourth embodiment, since the centering portion also serves as a spring receiver on the rear end side, after the return spring is placed in the spring installation chamber, the push shaft member can be immediately rotated to perform temporary fixing. A short time until the rotation is preferable from the viewpoint of preventing the displacement of the return spring. In the fourth embodiment, it is not necessary to add a centering portion to the push shaft member.

Hereinafter, a liquid pot according to a first embodiment of the present invention will be described with reference to the accompanying drawings (hereinafter simply referred to as “first embodiment”, and other embodiments are also abbreviated).

When the operation unit 50 is pushed while the handle 40 is held, the valve 21 is opened and the outer lid 30 is opened. When the container body 10 is tilted in this state, the storage through the inner plug 20 is performed. The liquid flows out from the spout 12 of the mouth part 11.

  The container body 10 has a double heat insulating container 13 having an open port on the upper surface and an outer container 14 in which the double heat insulating container 13 is accommodated. The outer container 14 has a shoulder member 15 that is closed between the outer insulated container 13 and the outer container 14. The mouth portion 11 is formed by the inner peripheral surface of the shoulder member 15 and the open mouth of the double heat insulating container 13. The spout 12 is formed so as to protrude laterally at a part in the circumferential direction of the mouth 11. The spout 12 can be omitted. The shoulder member 15 is formed by integral injection molding of resin.

  A handle 40 is fixed vertically on the side surface of the outer container 14. The handle 40 is formed by integral injection molding of resin.

  As shown in FIGS. 1 to 3, the operation unit 50 guides the push button member 51 pushed into the shoulder member 15 side of the container body 10 with respect to the upper portion of the handle 40, and the sliding movement of the push button member 51 in the advancing / retreating direction. A button insertion portion 52 to be moved, a push shaft member 53 that moves forward and backward integrally with the push button member 51, and a return spring 54 that is interposed between the push shaft member 53 and the shoulder member 15 while being passed through the push shaft member 53. Consists of. The forward direction of the push button member 51 is a direction from the handle 40 side toward the container body 10 side. The inner periphery of the shaft outlet 16 formed in the shoulder member 15 supports the container body 10 side of the push shaft member 53. The push button member 51 supports the handle 40 side of the push shaft member 53. With these supports, the push shaft member 53 faces the interlocking member 60 incorporated in the inner plug 20 with the push button member 51 attached, as shown in FIGS. 1, 2, and 4.

  Specifically, as shown in FIG. 3, the button slot 52 is integrally formed so as to open rearward. Further, as shown in FIG. 5, the button insertion portion 52 has grooves 52 a and 52 b into which the engaging portions 51 a and 51 b protruding from both sides of the push button member 51 are fitted. The engaging portions 51a and 51b are hooked on the closed ends of the grooves 52a and 52b on the backward side, and prevent the push button member 51 from coming off against the return spring 54.

  As shown in FIGS. 2 and 3, the handle wall portion 55 that forms the front end of the button insert portion 52 includes a shaft insert port 55 a for inserting the push shaft member 53 into the shaft outlet hole 16 of the shoulder member 15, and a handle fixing portion. And a screwing portion 55b. A spring installation space 56 for accommodating the return spring 54 is formed between the shaft insertion port 55 a and the shaft output port 16. The return spring 54 is a coil spring that can be passed through the push shaft member 53 from the front end side. The shaft insertion port 55a is provided so that the push shaft member 53 can be inserted together with the return spring 54 from the front end side.

  Centering portions 57, 57, 57 that partially contact the inner periphery of the spring installation space 56 are formed on the outer periphery of the push shaft member 53 so as to protrude from the return spring 54. The centering portions 57, 57, 57 are spring receivers that hold the rear end of the return spring. Each centering portion 57 is equally distributed in three circumferential directions around the shaft center, and the center of the push shaft member 53 is brought into contact with the inner periphery of the spring installation space 56 regardless of the rotation angle of the push shaft member 53. You can get out. The form, number, and arrangement of the centering portions 57 are not particularly limited as long as a desired centering is obtained regardless of the rotation angle of the push shaft member 53.

  As shown in FIGS. 2 and 3, the shaft insertion port 55a is formed with notches 55c, 55c, and 55c through which the centering portions 57 pass. Each centering portion 57 is inserted into the spring installation space 56, and the push shaft member 53 is rotated in a state where the push shaft member 53 is inserted from the shaft insertion port 55a to the shaft alignment port 16, so that the notch portions 55c and 55c are rotated. , 55c. Even if the hand is released from the push shaft member 53, it is caught by the handle wall 55 due to the rebound of the return spring 54. The push shaft member 53 is prevented from coming off by this catch. As a result, the push shaft member 53 is temporarily fixed by centering and retaining.

  As described above, in the first embodiment, the push shaft member 53 can be temporarily fixed by a simple operation of inserting and rotating the push shaft member 53 from the shaft insertion port 55a to the shaft ejection port 16.

  Further, in the first embodiment, since the centering portions 57, 57, 57 also serve as spring receivers on the rear end side, after the return spring 54 is placed in the spring installation chamber 56, the push shaft member 53 is immediately rotated to temporarily Fixing can be performed.

  In the state temporarily fixed as described above, as shown in FIG. 5, the push button member 51 is pushed into the button insertion portion 52, thereby engaging the engagement portions 51 a and 52 b of the push button member 51 and the button insertion portion 52. Can be engaged. In this way, the rear end of the push shaft member 53 is pushed by the push button member 51 attached to the button insertion portion 52. As a result, each centering portion 57 is positioned away from the handle wall 55. Due to the engagement between the engagement portions 51 a and 52 b of the push button member 51 and the button insertion portion 52, the push shaft member 53 is maintained in a state where it hits the front end 51 c of the push button member 51. For this reason, each centering part 57 does not retreat the notch part 55c.

  As described above, in the first embodiment, the push button member 51 is used to prevent the centering portions 57 from retreating the notch portions 55c, so that a structure for preventing the rotation of the push shaft member 53 is added. Thus, the push operation of the push button member 51 can be reliably performed.

  The relationship between the push button member 51, the button insertion portion 52, and the push shaft member 53 is that each centering portion is closer to the container body 10 than the joint 58 between the shoulder member 15 and the handle 40 existing on the inner periphery of the spring installation space 56. The front end of 57 is always set. “Always” means that the push shaft member 53 can be moved back most. In the first embodiment, it means that the backward restriction by the push button member 51 is effective. For this reason, in the first embodiment, there is no possibility that each centering portion 57 is caught by the joint 58 when the push button member 51 is pushed.

  The operation unit 50 assembled as described above can push the push button member 51 while holding the handle 40, tilt the container body 10, and pour the stored liquid from the spout 12 of the mouth portion 11. . As shown by the solid line in FIG. 1, when the push button member 51 is pushed toward the container body 10 against the return spring 54 as shown in FIG. The front end portion of the push shaft member 53 that advances integrally with the push button member 51 protrudes from the shaft opening 16 formed in the shoulder member 15 to move the opening / closing interlock mechanism. That is, the interlocking member 60 is pushed in the forward direction against the second return spring 61 incorporated in the inner plug 20. 6B, the sliding contact portion 62 of the interlocking member 60 that is pushed and moved by the front end portion of the push shaft member 53 comes into sliding contact with the first tapered surface 31 provided on the outer lid 30. As shown in FIG. 6C, the outer lid 30 is rotated to the opening stop angle by this sliding contact. While the push operation of the push button member 51 is maintained, the outer lid 30 is maintained at the opening stop angle by the stop contact between the sliding contact portion 62 and the first tapered surface 31. When the push operation is lost, the push button member 51 and the push shaft member 53 are retracted by the elastic repulsion of the return spring 54 and the second return spring 61 until the engaging portions 51a and 51b are engaged as shown in FIG. As shown in FIG. 1, the outer lid 30 opens and the angle returns to 0 degrees. As shown in FIG. 6A, the second tapered surface 63 provided on the interlocking member 60 slides on the upper end of the valve 21 at a timing later than the timing at which the sliding contact with the first tapered surface 31 starts. In this sliding contact, the valve 21 moves to the lowering stop position against the third return spring 22 incorporated in the inner plug 20. As shown in FIG. 6B, the sealing surface of the valve 21 is separated from the sealing surface provided on the inner plug 20 by lowering. At this time, if the container body 10 is tilted forward, the stored liquid can flow toward the spout 12 through the flow path in the inner plug 20. As shown in FIG. 6C, while the push operation of the push button member 51 is maintained, the valve 21 is maintained at the lowering stop position by the stop contact between the upper end portion thereof and the second tapered surface 63. As the push operation disappears and the interlocking member 60 moves backward, the valve 21 rises to the ascending stop position due to the elastic repulsion of the third return spring 22. As shown in FIG. 1, when the opening angle is 0 degree, the valve 21 is in the ascending stop position.

  The opening / closing interlock mechanism of the first embodiment performs the above-described series of operations as a result of the operation member 60 being moved by the push shaft member 53 of the operation unit 50, thereby performing the opening / closing operation of the outer lid 30. And the opening / closing operation of the valve 21, that is, the opening / closing operation of the mouth portion 11. The opening / closing interlock mechanism is not limited to the one as in the first embodiment, and any mechanism that can be incorporated into the container body 10 and moved by the push shaft member 53 may be used. When the opening operation of the outer lid 30 is started earlier than the opening operation of the valve 12 as in the above-described opening / closing interlocking mechanism, the pushing operation of the operation unit 50 and the tilting of the container body 10 are performed simultaneously with the handle 40 being held. In the case of an erroneous operation in which the pushing operation is performed in a state where the container body 10 is tilted, it is possible to make it difficult for the stored liquid that has passed through the inner plug 20 to be applied to the inner surface of the outer lid 30 from the spout 12.
