Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lid structure suitable for being attached to a container main body that stores a wet object or liquid as an object to be stored.
[0002]
[Prior art]
Conventionally, as shown in FIG. 10, for example, a lid structure for a container for containing a liquid or a wet object has been known.
In the figure, the lid 1 is attached to the main body side 2 of the container by a hinge 3 so as to be opened and closed.
The container main body side 2 shown in the figure is actually a cap main body, and is mounted by screwing a screw portion 6 into a container for storing a liquid.
A spout 4 is provided on the container main body side, and is closed by the inner plug 5 when the lid 1 is closed.
[0003]
In such a lid structure as shown in FIG. 10, when the locking mechanism is released after the lid 1 is closed, the lid 1 is opened by the restoring force of the elastic member 7 provided in the vicinity of the hinge 3 to open the lid. It is designed to maintain the state. Thereby, when pouring the liquid which is a storage thing from the spout 4, the cover 1 is made not to become obstructive.
[0004]
[Problems to be solved by the invention]
In the lid structure described above, since the container contents are liquid, the elastic member 7 provided in the vicinity of the hinge 3 is formed of a synthetic resin such as silicone, for example, and the elastic member 7 is loaded with the contents. I try not to rust.
However, in the case of using a synthetic resin such as silicone rubber as a spring, there is not enough elastic force to open the lid 1 at a speed that the user can satisfy with ease of use.
[0005]
In addition, rubber such as silicone rubber and elastic bodies made of synthetic resin have a problem that it is difficult to maintain the initial performance because they are likely to change due to environmental changes and aging.
Therefore, sufficient torsional elasticity can be used by using a generally used metal torsion spring instead of the above-described silicone rubber or the like. However, such a torsion spring is easily rusted and has a problem that it is particularly unsuitable for a lid of a container for storing a liquid or a wet container.
[0006]
The present invention has been made to solve such a problem, and is a lid structure for a container containing a wet object or liquid, which can be opened at a practically sufficient speed, It is an object of the present invention to provide a lid structure for a container that is not easily deteriorated over time.
[0007]
[Means for Solving the Problems]
According to the present invention, the object is to provide a base part that covers at least a part of the upper surface of the container body, an opening formed in the base part for taking out the wet contents or liquid of the container body, and a base part. A lid body that is attached to the base portion to open and close the opening of the base portion, a locking means for the lid body provided on the base portion, and disposed between the lid body and the base portion A metal torsion spring, and a cover member that prevents the torsion spring from being exposed to the outside when the torsion spring is attached, the cover member accommodating the torsion spring and the lid The cover member is attached to and detached from the body or the base portion, and the cover member is used for attaching and detaching the concave portion for accommodating the torsion spring. Includes an inner unit, the lid or the base part, have the guide portion is provided corresponding to the guide means, one of the guide portion and the guide means is a guide groove, the other is A guide protrusion that enters the guide groove, and a rotation center of a hinge that connects the lid body and the base portion by inserting the guide protrusion into the guide groove and mounting a base member, and a center of the torsion spring Is achieved by the lid structure of the container which is configured to substantially coincide with each other.
[0012]
According to the above configuration, the torsion spring is provided between the lid and the base portion. For this reason, when the lid is opened, a torsional stress acts, and a sufficient biasing force is applied to the lid. Therefore, the lid can be opened at a high speed. And since this torsion spring is covered with the cover member, even when taking out wet contents from the container body, the torsion spring does not get wet and rust, so the lid structure may not function. Absent.
[0013]
When the cover member accommodates the torsion spring and can be attached to and detached from the lid or the base member, the torsion spring can be easily attached in the comparative period, and the torsion spring can be removed from moisture. Easily protected.
[0014]
The cover member includes a recess for accommodating the torsion spring and guide means used for attachment and detachment, and the lid or the base part is provided with a guide part corresponding to the guide means. Then, the torsion spring can be more easily mounted using the guide means and the guide portion. In this case, one of the guide means and the guide portion is a guide groove, and the other is a guide protrusion that enters the guide groove, and by inserting the guide protrusion into the guide groove and mounting the base member, If the center of rotation of the hinge connecting the lid and the base and the center of the torsion spring are configured to substantially coincide with each other, the torsion spring can be easily mounted and the positioning can be easily performed. it can.
[0015]
The locking means of the lid is a locking portion that is disposed opposite to the tip of the lid and is formed integrally with the base member, and the locking portion is displaced based on elasticity. Thus, when the lid is configured to be engaged with and disengaged from the front end, the region to be operated by the user is easily grasped when the lid is opened, and the usability is improved.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferable specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention particularly limits the present invention in the following description. As long as there is no description of the effect, it is not restricted to these aspects.
[0017]
FIG. 1 is a schematic perspective view showing an entire container to which a lid structure according to a preferred embodiment of the present invention is applied.
In FIG. 1, a container 10 includes a container main body 13, a base member 11 attached to the container main body 13, a lid 12 fixed to the base member 11, and a retainer that holds the lid 12 in a closed state. Stop means 14.
[0018]
The container main body 13 has a shape and a size required to accommodate the contents. In the case of the container 10, the container main body 13 is made of wet paper or non-woven cloth soaked with liquid. Many types of napkins or tissues are folded and stored. For this reason, the container main body 13 has a rectangular parallelepiped box shape that is long horizontally, and the upper part is open, making it easy to store the contents.
[0019]
The base member 11 is attached to the upper portion of the container body 13 so as to close the opening of the container body 13, and is formed of a material having some elasticity such as polypropylene (PP), and has a thin plate shape as a whole. It is a member. The base member 11 is provided with a fold back at the periphery so that it can be fitted into the upper portion of the container body 13.
[0020]
Near the center of the upper surface side of the base member 11, an elliptical recess 19 is provided as shown in FIG. The concave portion 19 is formed so as to follow the shape of the lid body 12, and a central recess is a second concave portion that is further depressed. The second-stage recess 19a is substantially elliptical, and a bottom surface is provided with a take-out port 18 as an opening in which a slit is formed in an H shape.
[0021]
As a result, the base member 11 seals a large number of wet items contained in the container body 13 while being folded. In addition, when the lid 12 described later is opened, when the contents folded for each usage unit are pulled out for each usage unit from the take-out port 18, this is partially folded and stored for the next time. The H-shaped slit prevents the contained material from being pulled out together. In addition, since the contents to be used for the next use are fully held by the H-shaped slit 18 so that a part of the contents to be used this time is pulled out, the next thing to be withdrawn. Sometimes convenient. In addition, the slit 18 as an extraction port is not limited to an H-shape, and any other configuration may be used as long as it has a similar function.
[0022]
The lid 12 has a shape in which the outer periphery enters the recess 19, and an elliptical ridge 12 a is formed on the inner side. This convex shape 12a is adapted to enter the inner periphery of the second concave portion 19 of the base member 11 without a gap, whereby the water content of the content in the container body 13 evaporates and the content is dried. It is prevented.
The lid 12 is fixed to the back side of the base member 11 in FIG.
Specifically, support shafts 16 a and 16 a extending outward on the left and right sides are formed on the peripheral edge of the back side of the lid body 12, and the support shafts 16 a and 16 a of the recess 19 of the base member 11 are formed. It passes through a shaft hole (not shown) formed near the left and right ends on the back side (see FIG. 7). The lid 12 is fixed to be openable and closable by a hinge 16 constituted by the support shafts 16a and 16a and a shaft hole on the base member 11 side.
[0023]
Further, a torsion spring (torsion coil spring) is mounted between the support shafts 16a and 16a of the lid 12 as shown in FIG.
As shown in FIGS. 3 and 4, the cover member 17 is a holding member for a torsion spring formed of plastic or the like. The cover member 17 has a recess 17 a for accommodating the torsion spring 15. The recess 17a has a groove 17b that completely accommodates one end of the torsion spring 15 and a groove 17c that leads the other end of the torsion spring 15 to the outside.
[0024]
Further, guide projections 17d and 17d are formed on both sides of the cover member 17 so as to project integrally. The guide protrusions 17d and 17d correspond to guide means in the present embodiment.
On the other hand, in FIG. 2, a guide groove 21 shown in FIG. 5 is formed between the support shafts 16 a and 16 a of the lid body 12. This guide groove 21 is a guide part in this embodiment. The guide groove 21 is open at the lower end so as to receive the cover member 17 from below. That is, when the guide protrusions 17 d and 17 d of the cover member 17 are inserted into the guide groove 21 of the lid body 12, the step portions 17 e and 17 e of the cover member 17 come into contact with the terminal end portion of the guide groove 21 to be positioned. ing.
[0025]
As a result, the center of the coil of the torsion spring 15 accommodated in the cover member 17 substantially coincides with the axis of the support shafts 16a and 16a of the lid 12 and substantially coincides with the rotation center of the lid 12. ing. In this state, one end of the torsion spring 15 abuts on the lid body 12 and the other end is led out from the groove 17c of the cover member 17 to form a hole formed in the base member 11 as shown in FIG. By being accommodated in 11b, it is in contact with the base member 11 side.
The base member 11 is provided with a relief groove 11a according to the trajectory of the cover member 17 that moves as the lid body 12 rotates so as not to interfere with the locus.
[0026]
Therefore, the lid 12 is biased in the opening direction based on the torsional elasticity of the torsion spring 15. This urging force is larger than that of an elastic body made of plastic such as silicone rubber as in the prior art, and becomes a rotational torque for opening the lid 12, so the lid 12 opens quickly at a practically sufficient speed. be able to.
Furthermore, since the outer side of the torsion spring 15 is almost completely covered with the cover member in the mounted state, the torsion spring 15 does not get wet when taking out the wet contents accommodated in the container main body 13, and is therefore made of metal. The torsion spring 15 does not rust.
[0027]
Further, the insertion and positioning of the torsion spring 15 can be performed only by inserting the guide protrusion 17d as the guide means of the cover member containing the torsion spring 15 into the guide groove 21 as the guide portion provided as the guide portion provided on the lid 12. Easy to do. As a result, the assembling work becomes very simple, and the manufacturing cost of the container 10 can be reduced accordingly.
It should be noted that the center of the coil of the torsion spring 15 accommodated in the cover member 17 may be substantially coincident with the axis of the support shafts 16a, 16a of the lid body 12, and need not be exactly the same. It only needs to be substantially coincident with the center of rotation of the lid body 12 and may be positioned to such an extent that the torsional elasticity of the torsion spring 15 can be used as the rotational torque of the lid body 12.
Further, the torsion spring 15 mounted in this way is housed in the cover member 17 and is fixed to the accessory body 12 even when the lid 12 is forcibly opened, so that it jumps out toward the user. There is no safety. Further, in such a case, the torsion spring 15 does not come off alone, so that an infant or the like does not accidentally drink it, and can be used safely in this respect.
[0028]
FIG. 8 shows the locking means 14 for the base member 11 and the lid 12. FIG. 8 is a cross-sectional view crossing the base member 11 and the lid body 12 in FIGS. 1 and 2 in the front-rear direction.
In the figure, the locking means 14 is provided at a position facing the tip of the lid 12. Specifically, the locking means 14 has a lever portion 29 which is formed by extending a portion formed integrally with the base member 11 in the right direction in FIG. 8 and folding back at the right end portion 26 of the base member 11 in the arrow A direction. have. As shown in FIGS. 1 and 2, the lever portion 29 appears in a semicircular shape on the front side of the base member 11.
[0029]
Moreover, a gap 8 is formed between the folded lever portion 29 and the upper surface of the base member 11, as shown in FIG. 8, so that the lever portion 29 has a base portion based on its elasticity. 11, the inner side (left side) swings in the direction of arrow B, with the vicinity of the right end portion 26 as the center.
[0030]
In FIG. 8, a locking claw 27 as a locking portion having a gradually descending inclined surface and a downward stepped portion is provided at the inner (left side) tip of the lever portion 29. On the other hand, the front end of the lid 12 is provided with a locking claw 12b as a locked portion having an inclined surface inclined in the opposite direction to the locking claw of the lever portion 29 and an upward stepped portion. Yes.
[0031]
The locking means configured in this way operates as follows. As shown in FIG. 8, when the lid 12 is open and the lid 12 is held open by the biasing force of the torsion spring 15, the user moves the lid 12 to the biasing force of the torsion spring 15. Against this, close it in the direction of mark C. At this time, the inclined surface of the locking claw 12b formed at the front end portion of the lid body 12 and the inclined surface of the locking claw 27 of the lever portion 29 come into contact with each other and slide to each other. By the deformation, the upward stepped portion of the locking claw 12b and the downward stepped portion of the lever portion 29 are engaged and locked (see FIG. 9).
[0032]
On the contrary, as shown in FIG. 9, when the lever portion 29 is pushed from above with the lid 12 closed, the lever portion 29 swings downward in the direction of arrow B in FIG. The engagement between the stepped portions of the locking claws 27, 12b is released. As a result, the lid 12 is opened in the direction of arrow C in FIG. 8 by the urging force of the torsion spring 15.
[0033]
In this case, in the locking means of this embodiment, the lever portion 29 is formed in a substantially semicircular shape as shown in FIGS. 1 and 2, so that the user tries to open and close the lid 12. It is easy to visually recognize a portion to be operated when performing the operation, and the operation can be surely performed.
Moreover, since the lever part 29 is integrally formed by the same material as the base member 11 as mentioned above, manufacture is easy and it can hold down manufacturing cost low.
[0034]
Thus, according to the container lid structure of the present embodiment, the torsion spring 15 is used to open the lid 12, so that the container 12 can be quickly opened with a sufficient urging force.
Further, since the torsion spring 15 is covered by the cover member 17, when the wet contents are taken out, the metal torsion spring 15 does not get wet and the torsion spring 15 can be prevented from rusting. For this reason, the torsion spring 15 does not rust during use of the container 10 and its function is not incomplete, and rust does not come out and it becomes unsanitary.
[0035]
Even when the lid 12 is forcibly opened, the torsion spring 15 is accommodated in the cover member 17, so that the torsion spring 15 is detached and flies in a direction dangerous for the user. Never do.
Further, as shown in FIGS. 1 and 2, the lever member 29 is partitioned so as to be easily visible, so that the lid body 12 can be reliably opened and closed.
[0036]
The present invention is not limited to the above-described embodiment.
The container body 13 may be formed in a bottle shape and contain a liquid. In this case, the base member 11 can be shaped like a cap or a cap body instead of a plate-like one as in the above-described embodiment. That is, as a base member, a cap body as shown in FIG. 10 may be provided, and a lid that is opened by a torsion spring may be provided thereon.
[0037]
A base member that accommodates the torsion spring may be attached to the base member, and one end of the torsion spring may be in contact with the lid.
Further, a guide groove may be provided in the base member, and a guide protrusion may be provided on the lid or the base member side.
[0038]
