Description

  The present invention relates to a wet tissue container used in a state in which a wet tissue package accommodated in a soft packaging bag or the like is stored, and more particularly to the structure of a push button as an opening / closing mechanism for an outlet of stored items.

  Containers used with wet tissue packages stored in flexible packaging bags, etc., have a certain degree of sealing to prevent the stored items from drying when not in use. Containers that can be easily resealed after opening and removing only the required amount have been used.

  Such a container includes a container main body having an outlet on the upper surface and an open (opened) lower surface, and a bottom lid that fits and seals the lower surface of the container main body. An opening / closing lid that covers the outlet provided in the container in an openable / closable manner, a resilient plate that urges the rear of the opening / closing lid upward from the lower surface of the rear of the opening / closing lid, and the front of the opening / closing lid engaged with the container body to seal or open the outlet A container composed of a push button for performing the above is common.

  Conventionally, however, this type of container has a large number of parts constituting the container, and therefore, the assembly process of the container has many processes, which has been a cause of cost increase. In addition, the complexity of the structure often causes problems with durability and stability.

  As an openable lid that can be assembled easily with a small number of components, in Patent Document 1, the top wall is extended from the container body in which the mouth and neck portions are erected and the peripheral wall upper end edge fitted to the outer periphery of the mouth and neck portions. The cap body has a recess for pushing down the cover plate at the rear of the top wall, and a swing hole is drilled in the front of the top wall. There has been proposed a dispensing container comprising a cover plate that can be covered, and a non-metallic elastic body that can be elastically compressed interposed on the bottom lower surface of the cover plate.

Further, in Patent Document 2, a container body in which an outlet is formed, an opening / closing lid that is swingably attached to the container body, and that seals the outlet, and a swinging portion between the container body and the opening / closing lid are provided. Elastic biasing means for biasing the opening / closing lid in the opening direction,
An operation that pushes the free end of the open / close lid to the free end side of the open / close lid of the container main body is provided with an engaging portion that engages with the lock portion at the free end of the open / close lid. The body is pivotably attached, and a spring material that contacts the container body is provided at the lower end of the operating body,
The operating body is located on the spring material side, and includes a first member extending in the vertical direction and a second member connected orthogonally to the first member and extending in the horizontal direction and having a rotating shaft attached to the container body. The first member and the second member are respectively formed with pressing portions that can be pressed from the outside, and the operating body is pivoted by pressing either the pressing portion of the first member or the pressing portion of the second member. And the second member pushes up the free end of the lid,
An openable / closable container has been proposed in which the spring material provided on the operating body is inclined downward and is in contact with the drop step portion of the container body.

According to these proposed containers, since metal springs are not used as a constituent material, there is no need for separation processing at the time of disposal, the lid plate can be kept closed and automatically closed, and the structure is simple. In addition, an excellent container that can be easily assembled is obtained.
However, as the characteristics in use, problems remain particularly in terms of durability and repulsive stability during repeated use.

  For example, as an example in which there is a spring that imparts cushioning properties in front of the push button, a case in which the shape of the spring is provided in an arc shape perpendicular to the rotation direction of the push button will be described. 1A is a schematic side view, and FIGS. 1B and 1C are schematic front views.

  The opening / closing mechanism of the entire container is shown in FIG. FIG. 5 shows a container main body having an outlet on the upper surface and an opening on the lower surface, and a bottom lid fitted to the lower surface of the container main body. And a resilient plate for urging the rear part of the opening / closing lid upward from the lower surface of the rear part of the opening / closing lid, and a schematic side view of the container comprising a push button for sealing or opening the outlet by engaging the front part of the opening / closing lid with the container body. , (A) shows a state in which the outlet is sealed by the open / close lid, and (B) shows a state in which it is opened.

  FIG. 5 shows a container main body (12) having an outlet (14) on the upper surface and an opening on the lower surface, and a bottom lid fitted to the lower surface of the container main body. An opening / closing lid (9) for covering the outlet (14) of the opening / closing opening, a resilient plate (coil spring) (15) for urging the opening / closing lid rear part upward from the lower surface of the opening / closing lid rear part, and the opening / closing lid front part to the container body ( 12 is a container comprising a push button (10) for engaging with 12) to seal or open the outlet (14).

  In the state where the opening / closing lid (9) of FIG. 5 (A) is sealed, the claw-like protrusion (6) on the rear end surface of the push button (10) is formed in the window hole (7) on the front end surface of the opening / closing lid (9). The opening (14) of the container body (12) is opened by pressing the entire opening / closing lid (9) downward by the repulsive force of the spring (not shown) of the front lower part of the push button (10). Is being prevented.

  In order to change from the state where the opening / closing lid (9) of FIG. 5 (A) is sealed to the state where the outlet (14) of FIG. 5 (B) is opened, the front upper surface of the push button (10) is pushed forward. The lower spring (not shown) is pressed and shrunk to rotate the push button (10) forward, the rear claw-like projection (6) is sprung up, and the window hole (7 ) And the outlet (14) of the container body (12) is opened by the force of the elastic plate (coil spring) (15) that urges the rear of the opening / closing lid (9) upward.

In FIG. 1A, a leaf spring (a) is provided in an arc shape perpendicular to the rotation direction of the push button on the front lower surface of the push button (100). The push button (100) is rotated about the shaft (3) fitted in the shaft hole (not shown) of the main body by pushing the upper front side by hand, and the plate spring (a) is moved accordingly. Compressed vertically.
Corresponding to the compressed amount, the claw-like projection (6) at the rear end of the push button (100) is rotated upward to be detached from the window hole (7) of the opening / closing lid (9). Then, the open / close lid (9) is opened upward by the upward biasing force of a coil spring (not shown), and the outlet is exposed. After the necessary amount of storage is taken out, the upper part of the opening / closing lid is pushed and the window hole (7) of the opening / closing lid (9) is fitted into the claw-like projection (6). Sealing is complete.

  When the push button having the structure shown above is used, the repulsive force of the plate spring (a) varies depending on the push position of the push button (100) during the opening operation. There was a problem that the repulsive force was not stable.

  Further, as shown in FIG. 1B, since the deformation of the portion of the plate spring (a) contacting the main body (13) is large, the repulsive force of the plate spring is strong and difficult to adjust, and the repulsive force When the number of the holes is reduced, there is a problem in durability, such as a gap is generated in a portion in contact with the flange (pedestal) of the main body (13) as shown in FIG. It was particularly difficult to select a material for a repulsive and highly durable leaf spring.
