Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container lid, and more particularly, to a container lid suitable for being attached to a container or the like that contains a volatile substance such as a fragrance.
[0002]
[Prior art]
Some containers for storing volatile substances such as fragrances are configured so that the opening areas of the openings can be made different depending on the change in volatilization amount of the stored items. As such a container, for example, a container having the following lid has been proposed. That is, the top plate portion of the prone lid is divided into a peripheral fixed portion and a central movable portion through a dividing line space, and the movable portion is radially arranged from the high central push portion and the central push portion. Each movable piece portion is coupled to the peripheral fixed portion by a pair of connecting shaft portions on both sides of the intermediate position in the inner and outer directions, and each movable piece portion is connected to the central pushing portion. It has a hinge part at an intermediate position with the connecting shaft part, and when the central push part is pushed down, the tip of each movable piece part opens upward, and when the tip of the movable piece part is pushed down, the central push part and each movable piece The part is configured to return to the original position, and the whole is integrally formed of resin. (Japanese Patent Laid-Open No. 10-291553)
[0003]
This type of lid has the advantage that the opening area of the opening can be widened as necessary, and the amount of volatilization of the stored item is large, so it was used with a normal narrow opening area at the beginning of use, and the volatilization amount decreased. In this case, the same effect can be obtained by widening the opening area. However, in the wide open state where the tip of each movable piece part is open upward, the connecting shaft part is always twisted to return to the original state, and each movable piece part is refracted at the hinge. However, there were still unsatisfactory parts in terms of stably maintaining a wide open state.
[0004]
[Problems to be solved by the invention]
The present invention is a lid that adheres to a container containing a volatile substance such as a fragrance as described above, and the size of the opening can be easily changed as necessary, and the opening area is narrow. In addition, the present invention proposes an excellent container lid that can maintain a stable state with a wide opening area, has an extremely simple structure, and can be integrally formed with a synthetic resin.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
As shown in the drawings, the lid 1 of the container of the present invention is integrally formed of a synthetic resin, and extends the top wall 3 from the upper end edge of the peripheral wall 2 and volatilizes the contents stored in the mounted container. A vent hole 4 and a window hole 5 for volatilization adjustment are provided. Moreover, the movable plate part 6 that closes the window hole 5 so as to be openable and closable is integrally provided so as to be elastically inverted downward.
[0011]
The vent hole 4 in the present invention is for volatilizing the contents of the container deposited in a normal state, and its shape, opening area, opening position, etc. can be appropriately selected. In the embodiment of FIG. 1, a large number of bowl-shaped vent holes extending in a line from the top wall 3 to the peripheral wall 2 are arranged in parallel on both sides. Further, in the embodiment shown in FIG. 4, a narrow band-like vent hole 4 extending in the front and rear sides is provided.
[0012]
The window hole 5 is opened by operating the movable plate portion 6 when the amount of volatilization of the stored contents in the attached container decreases with time or when a large amount of volatilization is desired. The shape of the movable plate portion 6 can be variously selected in accordance with the shape of the movable plate portion 6, for example, a belt-shaped one extending from the peripheral wall 2 to the top wall 3 as in the embodiment of FIG. Various ones having a radial belt-like portion as in the embodiment of FIG. 4 can be employed.
[0013]
Various forms of the movable plate portion 6 can be selected as long as the above-described requirements are satisfied, and the window hole 5 is normally closed by positioning the edge portion along the edge portion of the window hole 5. However, it is not necessary to completely seal the window hole 5 from the gist, and there is no problem in providing a slight gap or a finger-hooking through hole described later. In addition, the downward elastic reversal is possible by pressing the movable plate portion 6 which is stable in a normal state from above, elastically deforming the whole or a part, and further pushing it into a stable state where no load is applied. The shape can be variously adopted as long as the shape of the window hole formed in the peripheral wall 2 and / or the top wall 3 is closed.
[0014]
1 to 3 show an embodiment of the present invention. A lid 1 in this embodiment has a flat top wall 3 extending from an upper end edge of a cylindrical peripheral wall 2, and the peripheral wall 2. A belt-like window hole 5 extending from the lower part to the rear part of the top wall 3 is formed. Further, the lower end edge and the rear end edge of the window hole 5 are formed in an L-shaped plate having the lower end edge and the rear end edge connected through the thin hinge 7, respectively, and the thin hinge 7 crossing the bent portion. And a movable plate portion 6 configured to be elastically inverted downward is provided. Further, a finger hooking hole 8 is formed in the horizontal plate portion of the movable plate portion 6 as a finger locking means for returning the movable plate portion 6 elastically inverted downward. The form of the finger locking means is not limited to such a finger hooking hole, but may be a protrusion form that is gripped by a finger, although not shown.
[0015]
The lid 1 is used by being attached to a container 9 as shown in the drawing. In the illustrated example, the peripheral wall 2 is fitted and attached to the outer peripheral upper end of a cylindrical container 9. When there is a large amount of volatilization of the stored items in the mounted container at the beginning of use, the stored items are volatilized from the vent hole 4 with the window hole 5 shown in FIG. 1 closed. When the volatilization amount of the stored item decreases with time, or when it is desired to increase the volatilization amount specially, when the movable plate portion 6 is pushed down from the state of FIG. Hole 5 is opened. Further, when it is desired to return from the opened state of the window hole 5 to the closed state, the original state can be restored by placing a finger on the finger hole 8 formed in the belt-like plate portion 6d and pulling it up.
[0016]
When the horizontal plate portion 6a is pushed down from the state shown by the solid line in FIG. 2, the elastic reversal of the belt-like plate portion is elastically deformed so as to reduce the length of both the horizontal plate portion 6a and the vertical plate portion 6b. In this case, it is rotated around the point A, and around the point B in the vertical plate portion 6b. Then, as shown by the two-dot chain line in FIG. 2, the plate portions 6a and 6b return to the original state where they are not elastically deformed at the point C, and become stable at this position, and the elastic reversal is completed.
[0017]
4 to 6 show another embodiment of the present invention, and the lid 1 in this embodiment has a dome-shaped top wall 3 extending from the upper end edge of the peripheral wall 2. Further, the window hole 5 in the present embodiment has a pair of belt-like portions 5b extending in the front-rear direction from the pressing portion space 5a in which the front and rear edges form a substantially circular shape. The belt-like portion 5b is not limited to the two places in the illustrated example, and may be three or more places. Further, the shape of the pressing portion space 5a is not limited to this, and various shapes can be adopted according to the shape of the movable plate portion 6.
[0018]
In addition, the movable plate portion 6 is positioned at the edge portion along the edge portion of the window hole 5, and the lower end edge of the strip-shaped strip-shaped plate portion 6 d that is radially extended from the pressing portion 6 c at the center of the top wall 3 is strip-shaped. A thin hinge 7 that is integrally connected to the lower end edge of the portion 5b and traverses the upper and lower portions of each strip-like plate portion 6d is provided so that the movable plate portion 6 can be elastically inverted downward. In the illustrated example, a projecting portion having a hollow truncated cone shape is provided at the center of the pressing portion 6c, and a finger hooking hole 8 as a finger locking means similar to the embodiment of FIG. 1 is formed in the side wall of the projecting portion.
[0019]
Similarly, the lid 1 of this embodiment is used by being mounted on a container 9. Further, when the amount of stored items in the mounted container at the beginning of use is large, the stored items are volatilized from the vent hole 4 while the window hole 5 shown in FIG. 4 is closed. When the volatilization amount of stored items decreases with time or when you want to increase the volatilization amount specially, if you press down the pressing part 6c from the state of Fig. 1, each strip-like plate part 6d is elastic downward. And the window hole 5 is opened. Further, when it is desired to return from the opened state of the window hole 5 to the closed state, the original state can be restored by placing the finger on the finger hooking hole 8 and pulling it up.
[0020]
In the elastic reversal of the belt-like plate portion, when the pressing portion 6c is pushed down from the state shown by the solid line in FIG. 5, each belt-like plate portion 6d is elastically deformed so as to contract, and rotates around the point D, respectively. Then, as shown by a two-dot chain line in FIG. 5, each band-like plate portion 6d returns to the original state where it is not elastically deformed at the point E, becomes stable at this position, and elastic reversal is completed.
[0021]
【The invention's effect】
As described above, the container lid of the present invention is configured as described above, so that an appropriate amount of stored items can be volatilized from the vent hole 4 at the beginning of use. In the case where the amount of the gas is reduced, the window hole 5 is opened by sufficiently pressing down the movable plate portion 6 and elastically reversing, and the decrease in the volatilization amount can be sufficiently compensated. Further, since the movable plate portion 6 is elastically inverted downward, the window hole opening state can be stably maintained, and there is no inconvenience that the strip-like plate portion 6d is naturally closed. Furthermore, the structure is extremely simple and can be integrally formed with a synthetic resin, and there is an advantage that it can be manufactured inexpensively and easily.
[0022]
Also, there is an advantage that it is possible to give directionality to the opening direction of the window opening 5.
[0023]
Furthermore, since the lid of the second means is provided with many thin hinges 7, it has an advantage that the movable plate portion 6 can be reversed relatively easily.
[0024]
Further, the lid of the third means also has an advantage that the movable plate portion that is elastically inverted downward can be easily returned as necessary.
