Description

  The present invention relates to a compact container that can be rationalized in the manufacturing stage.

  A compact container generally has a container main body that contains cosmetics or an inner dish that contains cosmetics, and a lid that is hinged around the rear end of the container main body. The container main body and the lid body are configured to be locked with each other by providing a locking portion at the front end. And when the latching | locking part of a container main body and a lid body mutually latches, a compact container maintains the state closed, and the latching state of each other is operated by operating the latching | locking part of a container main body or a lid body When is released, the compact container is opened and ready for use.

  Various types of opening / closing and locking mechanisms between the container body and the lid have been proposed, but easy opening / closing operations are required. For example, the cosmetic container described in Patent Document 1 has been developed and proposed by the applicant of the present application, and releases the engagement between the hooks of the lid and the container body with a small pushing amount of the bush piece, In addition, an auxiliary force that pushes the hook of the lid in the disengagement direction is generated by pushing the bush piece.

  In this technique, the push-in direction and push-in amount of the bush piece are determined by the protrusions projecting on both side surfaces of the bush piece and the engagement recesses extending in the front-rear direction formed on both sides of the recess provided in the container body. It is set by dimensional relationship. The bush piece is integrated with the container body by pushing the bush piece into the recess and fitting the protrusion into the engagement recess.

JP-A-10-113219

  The technique of Patent Document 1 is advantageous because the lid can be opened and closed smoothly. However, since the mechanism that regulates the movement of the bush piece is based on the engagement of the engaging recess provided in the recess of the container body and the protrusion provided on the bush piece, the bush piece is used when the cosmetic container is manufactured. There is a problem that a large force is required because the protrusions are brought into frictional contact with both side surfaces of the recess until the protrusion is engaged with the engaging recess.

  An object of the present invention is to provide a compact container that does not require a large force when assembling a compact container, and can therefore realize assembly with good workability.

  In order to solve the above problems, a compact container according to the present invention includes a compact container body, a lid body that is hinged to an end portion on the rear side of the container body and configured to be openable and closable with respect to the container body; When the lid disposed at the front end of the container body is closed, the hook provided on the lid is locked to keep the closed state, and the hook is locked with the opening operation from the outside. An opening / closing member that releases the lid and releases the lid, and a biasing member that biases the opening / closing member so as to maintain a locked state with a hook provided on the lid. An accommodation recess for accommodating the opening / closing member in a front-rear direction is formed at an end portion on the side, and an engagement hook is formed on a side surface of the accommodation recess, and a piece on the side surface of the opening / closing member An engagement hook formed in the shape of a cantilever and provided at the distal end portion of the receiving recess of the main body; Combined and in which locking hooks to be engaged is formed.

  In the compact container according to the present invention, the opening / closing member is housed in a state in which the opening / closing member is allowed to move in the front-rear direction in the housing recess provided at the front end of the container body, and the opening / closing member is closed by the biasing member. When the lid is closed, the hook provided on the lid can be locked and closed by the opening / closing member, and the closed state is established by the biasing of the opening / closing member by the biasing member. Can be maintained. Then, by operating the opening / closing member in the direction to release the locking with respect to the hook against the biasing by the biasing member, the locking with respect to the hook can be released and the lid can be opened.

  Since a cantilever-shaped locking hook is formed on the side surface of the opening / closing member, the opening / closing member is opened / closed when the opening / closing member is received in the receiving recess of the container body and engaged with the engaging hook provided on the side of the receiving recess. When the member is pushed into the housing recess, the cantilever-like locking hook comes into contact with the side surface of the housing recess and bending occurs. For this reason, the pressing force to the housing recess by the locking hook is reduced, and the operation of housing the opening / closing member in the housing recess can be performed with a small force. That is, the opening / closing member can be easily fitted to the container body.

  Therefore, the workability in the assembly process of accommodating the opening / closing member in the container body can be improved, and a large force is not applied, so that the parts are not broken.

  Hereinafter, the most preferred embodiment of the compact container according to the present invention will be described. The compact container according to the present invention is capable of reliably closing the lid body with respect to the container body, and can be opened by an easy operation. In particular, the assembly process when manufacturing the compact container In this way, it is possible to improve workability.

  The opening / closing member is housed in the housing recess while being allowed to move in the front-rear direction with respect to the container body, and is biased in a direction (front direction) to engage with the hook provided on the lid by the biasing member. The lid can be securely closed, and the lid can be easily opened by moving the closing member in the direction to release the engagement with the hook (rearward) against the biasing of the biasing member. Is possible.

  In particular, the opening / closing member housed in the housing recess of the container body has a function as a cover for the peripheral structure including the urging member, thereby simplifying the design around the front end of the container body. It is possible to show the high-class feeling of a compact container.

  Hereinafter, preferred embodiments of the compact container will be described with reference to the drawings.

  In the figure, reference numeral 7 denotes an urging member, which is made of elastic rubber or a relatively soft synthetic resin, and corresponds to the recess 6a formed in the rear end 1a of the container body 1. It is adhered or fitted to the part to be done. When the lid 2 is closed, the biasing projection 7a provided at a position displaced from the rotation shaft 6c of the hinge projection 6b formed on the lid 2 comes into contact with the biasing projection 7a via the biasing projection 7a. The lid 2 can be always urged in the opening direction.

  A hook 8 is provided at the end 2 b on the front side of the lid 2. The hook 8 is for engaging with a hook 9 provided on the upper surface of the opening / closing member 3 to maintain the closed state of the lid body 2 with respect to the container body 1. The installation position of the hook 8 in the lid 2 is not particularly limited, and is preferably set as appropriate in relation to the installation position of the opening / closing member 3. In the present embodiment, the hook 8 is provided at approximately the center of the lid body 2 (approximately the center of the compact container A).

  Reference numeral 10 denotes a mirror disposed on the surface of the lid 2 facing the container body 1.

  The middle dish 5 is fixed to a recess 1c provided in the container body 1, and is located at a portion facing a front edge 5a, particularly a receiving recess 15 provided at a front end 1b of the container body 1 described later. The edge 5 a is formed so as to protrude forward from the recess 1 c of the container body 1 and cover the receiving recess 15. In addition, the shape, dimension, etc. of the edge part 5a formed in the inner tray 5 are set on the optimal conditions corresponding to the design of the compact container A.

  A housing recess 15 is formed at the front end of the container body 1 and substantially at the center. The accommodating recess 15 accommodates the opening / closing member 3 while allowing the container body 1 to move in the front-rear direction, and can accommodate the opening / closing member 3 so as to move smoothly. The opening / closing member 3 is formed with such a size that a large gap is not generated.

  Engagement hooks 16 are formed on both side surfaces of the housing recess 15, and a guide piece 15 a that is continuous with the bottom surface of the container body 1 is formed on the lower surface. Further, a predetermined distance (opening / closing member 3) from the guide piece 15 a is formed. A plurality of guide protrusions 15b are formed at positions separated from each other by a size substantially equal to or slightly larger than the thickness of the guide portion provided on the outer surface. A projection 15c that positions and holds the biasing member 4 is formed at a predetermined position above the guide projection 15b.

  The engagement hook 16 includes a base portion 16a that protrudes from the side surface of the housing recess 15 and a claw portion 16b that further protrudes from the base portion 16a, and is formed by the base portion 16a and the claw portion 15b. The angle is a right angle or a slightly acute angle. The engagement hook 16 is formed at a position corresponding to the approximate center of the height dimension of the opening / closing member 3.

  The opening / closing member 3 has a width dimension substantially equal to or slightly smaller than the dimension in the width direction of the accommodating recess 15 provided in the container body 1, and when the opening / closing member 3 is accommodated in the accommodating recess 15, the hook 9 is located on the front side of the lid 2. It is comprised so that it may oppose with the hook 8 provided in the edge part 2b.

  The opening / closing member 3 is formed in a U-shape in a side view having an upper piece 3a provided with a hook 9, a front piece 3b, and a lower piece 3c. Further, on both sides in the width direction of the opening / closing member 3, an upper piece 3a and a lower piece 3c are connected to form a side piece 3d, and a pair of slits 3e is formed at a predetermined position of the side piece 3d. A cantilever-like locking hook 17 is formed.

  The upper piece 3a, the front piece 3b, and the lower piece 3c constituting the opening / closing member 3 are configured as a decorative surface that defines the design of the compact container A, and are formed with a design corresponding to the design required for the compact container A. Is done.

  In particular, the lower piece 3c has a function as a guide portion that is inserted between the guide piece 15a and the guide projection 15b constituting the accommodating recess 15 provided in the container body 1 and guided in the moving direction. That is, when the opening / closing member 3 is housed in the housing recess 15, the lower piece 3 c is disposed so as to move in the front-rear direction along the upper surface of the guide piece 15 a and the upper surface of the lower piece 3 c is the guide protrusion 15 b. By being positioned below, when the counterclockwise turning force in FIG. 1 acts on the opening / closing member 3, this rotation is blocked by the guide projection 15b. Therefore, the opening / closing member 3 is allowed to move only in the front-rear direction with respect to the container body 1.

  The locking hook 17 includes a beam portion 17a and a claw portion 17b formed at the tip of the beam portion 17a. The angle formed by the beam portion 17a and the claw portion 17b is formed to be a right angle or a slightly acute angle. Further, the length of the beam portion 17a is not particularly limited, but when the claw portion 17b comes into contact with the claw portion 16b of the engagement hook 16 when the opening / closing member 3 is accommodated in the accommodation recess 15 of the container body 1, It is preferable that the claw portion 17b has a length and a cross-sectional dimension such that the claw portion 17b can be sufficiently bent so as to get over the stuffing portion 16b with a relatively small force.

  The dimension from the front piece 3b of the opening / closing member 3 to the claw portion 17b of the locking hook 17 is such that when the claw portion 17b abuts and engages with the claw portion 16b of the engagement hook 16 of the housing recess 15, the front piece 3b Is set to be flush with the surface of the front end 1b of the container body 1. The length of the lower piece 3c is set so that a sufficient gap 18 can be formed between the end of the lower piece 3c and the depth direction of the guide piece 15a when the opening / closing member 3 is in the position. .

  Prior to housing the opening / closing member 3 in the housing recess 15 provided in the front end 1b of the container body 1, the biasing member 4 is attached to the protrusion 15c. The urging member 4 is urged so that the hook 9 provided in the opening / closing member 3 and disposed in the housing recess 15 can be held in a state of being locked to the hook 8 provided in the lid 2. In this embodiment, the urging member 4 is configured to urge the opening / closing member 3 forward.

  The urging member 4 may be any member that can exhibit the above function, and for example, a push spring, a coil spring, a disc spring, or the like can be selectively employed. Further, it is not always necessary to use a metal spring, and even a tube having sufficient elasticity such as rubber or synthetic resin can be used. In the present embodiment, a synthetic resin tube is used as the urging member 4.

  Next, a procedure for housing the opening / closing member 3 in the housing recess 15 provided in the front end 1b of the container body 1 will be described. First, the urging member 4 is attached to the protrusion 15c of the housing recess 15, and the opening / closing member 3 is pushed in from the front side. As the opening / closing member 3 is pushed into the housing recess 15, the claw portion 17 b of the locking hook 17 provided in the opening / closing member 3 comes into contact with the claw portion 16 b of the engagement hook 16 provided in the housing recess 15. The beam portion 17a of the locking hook 17 is bent and the claw portion 17b gets over the claw portion 16b to be accommodated.

  When the claw portion 17b of the locking hook 17 gets over the claw portion 16b of the engaging hook 16 as described above, the lower piece 3c of the opening / closing member 3 is inserted so as to be sandwiched between the guide piece 15a and the guide projection 15b. Accordingly, the opening / closing member 3 can be guided by the both pieces 15a and 15b so as to move only in the front-rear direction of the container body 1.

  After the opening / closing member 3 is accommodated in the accommodating recess 15 of the container body 1, the compact container A can be assembled through a normal process.

  In the assembled compact container A, the housing recess 15 of the container body 1 is covered by the upper piece 3a, the front piece 3b, and the lower piece 3c of the opening / closing member 3, and the upper portion 3a has an edge portion 5a of the middle plate 5 on the upper portion. Is placed. For this reason, the guide piece 15a which comprises the accommodation recessed part 15, and the biasing member 4 arrange | positioned are not visually recognized from the outside, but it is possible to ensure the designability.

  In the compact container A configured as described above, when the lid 2 is closed by being brought close to the container body 1, the hook 8 provided on the lid 2 is engaged with the hook 9 provided on the opening / closing member 3 to be closed. It is possible to maintain the state. The opening / closing member 3 (hook 9) is urged forward by the urging member 4, so that the hook 9 can be reliably engaged with the hook 8.

  In use, the opening / closing member 3 is pushed backward (in the direction of the arrow shown in FIG. 1) to move the opening / closing member 3 against the urging force of the urging member 4. It is possible to release the engagement with respect to.

  In this embodiment, the engagement hooks 16 are provided on both side surfaces of the housing recess 15 provided in the container body 1 and the engagement hooks 17 for engaging the engagement hooks 16 are also provided on the opening / closing member 3. However, the two engagement hooks 16 and the engagement hooks 17 are not necessarily required, and may be formed on any one of the side surfaces.

  The compact container A according to the present invention can improve the workability at the time of assembly, and the mechanism part for opening and closing the lid body 2 is not visually recognized from the outside. It is advantageous to use as the container A.
