Description

  The present invention relates to a storage container for storing a wet wiper for cleaning.

  For wet wipers (also called wet sheets) used for cleaning around kitchens and toilets, so-called waisted sheets based on wood pulp are suitable, and they are folded into a palm-sized rectangle. Things are widely used. Such wet wipers are impregnated with cleaning chemicals such as water and alcohol in advance for easy cleaning. For this reason, the user takes out the wet wiper from the package and refills it into a dedicated storage container.

  As a wet wiper storage container, Patent Document 1 stores rectangular wet wipers stacked in a flat manner in a storage container in which the opening peripheral edge of the container body can be fitted into the inner surface of the lower peripheral edge of the lid. The container which takes out in order from the upper wet wiper is disclosed. Further, Patent Document 2 accommodates the wet wiper so as to lean against the rear surface part in the storage container in which the peripheral part of the lid part is fitted and sealed in the groove part provided in the peripheral part of the opening part of the container body, The storage container which takes out a wet wiper in order from the front part is indicated.

  However, in a storage container having a structure in which a container body and a lid are fitted as in Patent Document 1, it is difficult to seal the entire periphery of the opening with a uniform force. If the container body and the lid are tightly fitted to increase the airtightness, a large force is required to open and close the lid, and it becomes inconvenient to take out and use the wet wipers one by one during cleaning. In addition, since wet wipers are stacked and stored horizontally, there are problems that it is difficult to take out one by one and that it is difficult to intuitively grasp the remaining number.

  Further, when a storage container such as Patent Document 2 is repeatedly used for refilling for a long period of time, if the container body is worn or deformed by repeated opening and closing of the cover body, the container body and the cover body are loosely stored. The airtightness of the container cannot be maintained. In this regard, wet wipers generally consume about 1 pack (10 sheets) per month, but if airtightness cannot be maintained, the moisture impregnated in the wet wiper during storage Some of the volatile components such as alcohol and alcohol evaporate, and after one month, the stains are not easily removed.

  Further, in both Patent Documents 1 and 2, the lid is opened and closed on the long side of the container body, and the depth of the container body is small. Therefore, if the remaining number of wet wipers stored decreases or the weight of wet wipers stored decreases and the stored wet wiper becomes light, the container body will fall over when the lid is opened widely. Problems arise. And if there is no allowance for the opening / closing angle of the lid to avoid falling, there arises a problem that it becomes difficult to take out the wet wiper.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. Note that the same number is assigned to the same element throughout the description of the embodiment.

<First Embodiment>
First, the overall configuration of a wet wiper storage container (hereinafter simply referred to as “storage container”) 100 will be described. As shown in FIG. 1, the storage container 100 according to the present embodiment includes a container body 1 having an opening 10 through which a wet wiper 101 is inserted and removed, and a rear surface 12 of the container body 1 via a hinge portion 8. A lid body 2 that can be opened and closed and closes the opening 10 and a packing 5 that retains airtightness between the container body 1 and the lid body 2 are provided. 1A and 1B show a state in which the lid 2 is closed. As shown in FIG. 1A, the container body 1 has a longitudinal direction in the front-rear direction. Here, in the case of “front-rear”, the side on which the lid 2 is opened is “front”, and the lid 2 is The side held by the container body 1 is referred to as “rear”.

  As described above, the container body 1 has a longitudinal direction in the front-rear direction, and as shown in FIG. 1A, the folded rectangular wet wiper 101 is stored vertically with its long side facing sideways. ing. FIG. 1A shows a state in which five sheets of wet paper 101 are stored, but this is for illustrating a state in which the wet paper 101 is stored, and the number of stored sheets is limited to five. It is not a thing. Considering the thickness of one wet wiper 101 to be stored, for example, the width of the container body 1 is set to such an extent that approximately 10 sheets can be stored in anticipation of normal monthly consumption. By storing the rectangular wet wiper 101 folded in this way vertically, the width of the container body 1 and thus the entire storage container 100 can be reduced, and the space for placing on the shelf or the like can be saved. be able to.

  Moreover, since the long side of the wet wiper 101 is placed horizontally, that is, the short side is vertically oriented, the height of the storage container 100 can be kept low, and the opening / closing angle of the lid 2 can be increased. It is possible to suppress the overturning and to maintain high stability when the lid 2 is opened and closed with the container body 1.

Here, preferred specifications of the wet wiper 101 will be described. As the wet wiper 101, one sheet or two to four sheets containing wood pulp having a weight of 90% or more are used. The total basis weight is preferably 65 to 100 g / m ² , and after cutting into a rectangle of a predetermined size, the short side length is 70 mm to 90 mm and the long side length is 100 mm to 150 mm. Fold it so that This dimension is determined in consideration of a size that can easily fit in the palm of the user. The sheet is impregnated with a liquid containing water, an aqueous solvent, a preservative, and a fragrance at a weight that is 1.3 times or more and 2.0 times or less the weight of the sheet, depending on the degree of dirt in the kitchen or toilet. . If it is less than 1.3 times, the chemical solution does not spread evenly over the entire sheet, making it difficult to remove dirt cleanly. If it exceeds 2.0 times, the strength of the sheet will be reduced, or twice due to the occurrence of uncleaned chemicals. There are problems such as the need for wiping.

  The container body 1 is formed such that the upper edge 11a of the front surface 11 is lower than the upper edge 12a of the rear surface 12, as shown in FIG. As will be described later, the height of the upper edge 12a of the rear surface 12 of the container body 1 is larger than the length of the short side of the wet wiper 101 to be accommodated, and the height of the upper edge 11a of the front surface 11 of the container body 1 is It is set lower than the length of the short side of the wet wiper 101. In this way, the end portion on the front surface 11 side of the wet wiper 101 stored in the container main body 1 with the long side facing sideways is opened from the opening 10 of the container main body 1 after the lid 2 is opened. Will also be exposed to the outside. Therefore, it becomes easy for the user to pick the exposed end portion, and it is possible to easily take out the arbitrary wet wiper 101.

  Returning to FIG. 1A, the front surface 11 of the container body 1 is formed in a curved surface that protrudes outward in plan view. By making the front surface 11 a curved surface, the cosmetics of the storage container 100 is enhanced, and the opening 10 becomes convex outward on the front surface 11 side. This makes it easier to take out the wet wiper 101 from the front surface 11 side. When the front surface 11 is a curved surface that protrudes outward, it is difficult to display a normal adhesive label on the front surface 11 or display by silk printing, but a product display or design is applied to a stretchable film formed in a cylindrical shape. By mounting on the container body 1, it is possible to display on the front surface 11 of the container body 1. As the stretchable film, polyethylene, polyurethane, polyvinyl chloride, or the like can be used.

  Here, FIG. 1C shows an enlarged view of a cross section of the packing 5. The packing 5 has a hollow cross section having an outer diameter and an inner diameter, and maintains the airtightness between the container body 1 and the lid body 2 by utilizing this hollow cross section, as will be described later. .

  Next, a configuration for maintaining the airtightness of the storage container 100 will be described. The broken line in FIG. 1A shows the structure around the opening 10 of the container body 1 covered with the lid 2. A flange-shaped protrusion 10 a is formed around the opening 10, and the first rib 3 that surrounds the entire periphery of the opening 10 in the protrusion 10 a and the second rib that surrounds the entire periphery of the first rib 3. 4 is formed. An annular packing 5 having no end is fitted and attached to a groove-like gap 34 formed between the first rib 3 and the second rib 4.

  The lid 2 is formed with third ribs 6 positioned so as to face the gap 34 with the opening 10 closed, and surrounding the entire periphery of the opening 10 of the container body 1. When the lid 2 is closed, the third rib 6 presses the packing 5. Furthermore, a fourth rib 7 is formed on the lid 2 so as to surround the entire circumference of the opening 10 of the container body 1 along the third rib 6 inside the third rib 6.

  The relationship between the first rib 3, the second rib 4, the third rib 6, the fourth rib 7, and the packing 5 will be described in more detail with reference to FIGS. FIG. 2 is a cross-sectional view of the storage container 100 as viewed from the side, and shows a case where the lid 2 is opened and a case where the lid 2 is closed. When the lid 2 is opened, the wet wiper 101 housed vertically in the container body 1 with the long side facing sideways is, as described above, the upper part of the front end (the left side in the figure) from the container body 1. Exposed to the outside.

  The airtightness when the lid 2 is closed will be described with reference to FIG. 3 and FIG. 3 shows the front end side of the storage container 100, and FIG. 4 shows the rear end side of the storage container 100, and a groove-like gap formed between the first rib 3 and the second rib 4 of the container body 1. The packing 5 is fitted and attached to 34, and the third rib 6 of the lid 2 presses the packing 5. The fourth rib 7 of the lid body 2 is disposed on an extension line of the side wall of the container body 1 in a state where the lid body 2 is closed. As a result, when the lid 2 is closed, the third rib 6 presses the packing 5 and the fourth rib 7 abuts against the container body 1, so that the airtightness of the storage container 100 is further enhanced. This configuration is provided over the entire circumference of the opening 10 of the container body 1.

  The fourth rib 7 protrudes below the third rib 6 and is formed so as to fit inside the first rib 3 of the container body 1. For this reason, even if the container body 1 or the lid body 2 is distorted with the lid body 2 opened, the third rib 7 is fitted inside the first rib 3 when the lid body 2 is closed. The rib 6 is accurately guided on the packing 5. Further, the fourth rib 7 supports the lid body 2 on the extension line of the side wall of the container body 1 and prevents the lid body 2 from being pushed and an excessive force applied to the packing 5 and the third rib 6.

  The packing 5 is formed in a ring shape from an elastic material selected from the group consisting of silicone resin, elastomer resin and urethane resin, and silicone resin is particularly preferable from the viewpoint of durability. The packing 5 is formed in a hollow shape having a cross section having an outer diameter and an inner diameter, and can be easily fitted in the gap 34 formed between the first rib 3 and the second rib 4 of the container body 1. After the fitting, the outer surface is pressed against the side surfaces of the first rib 3 and the second rib 4 and the bottom of the gap 34. Further, along with the closing of the lid 2, the packing 5 is further deformed by being pressed by the third rib 6 of the lid 2, and further strongly against the bottoms of the first rib 3, the second rib 4, and the gap 34. The gap 34 is sealed by being pressed, and the airtightness of the storage container 100 is maintained.

  The packing 5 can be sized according to the specifications of the storage container 100, but assuming the specifications of the storage container 100 derived from the size of the wet wiper 101 described above, the packing 5 is 1.8 mm or more and 2.9 mm or less. It is preferable to have an outer diameter of If the thickness is less than 1.8 mm, the deformable amount in the pressing direction becomes small, and the airtightness due to the pressing of the third rib may not be sufficiently exhibited. If the thickness exceeds 2.9 mm, the deformation amount of the packing increases, The required amount of the gap between the first rib and the second rib to be fitted is enlarged, and the heel portion of the container body is enlarged, which may affect the balance of the center of gravity and the cosmetics of the entire container. The inner diameter of the packing 5 is 70% or more of the outer diameter in consideration of the ease of fitting in the gap 34, the expandability after fitting, and the deformability when pressed by the third rib 6. 80% or less is preferable. If it is less than 70%, it will be difficult to tighten the lid due to the high resilience resulting from the strong elasticity of the packing, and if it exceeds 80%, the elasticity of the packing will be weak, resulting in sufficient airtightness over a long period of time. It becomes difficult to maintain. And when the packing 5 is pressed by the 3rd rib 6 with closure of the cover body 2, it is preferable to have a deformation amount of 20% or more and 30% or less of the outer diameter in the radial direction. If it is less than 20%, a gap is formed between the rib and the packing, and the adhesive force is weakened so that sufficient airtightness is hardly exhibited. If it exceeds 30%, it is difficult to tighten the lid due to excessive elasticity of the packing.

  The gap 34 of the container body 1 is not less than 80% of the outer diameter of the packing 5 in consideration of the ease of fitting the packing 5 and the expandability to the first rib 3 and the second rib 4 after fitting. % Or less is preferable. If it is less than 80%, the workability of the packing mounting process at the time of container production is lowered, and if it exceeds 93%, the packing is not sufficiently fixed, and it is easy to come off in the process of repeatedly opening and closing the lid.

  As described above, in this embodiment, since the elastic packing 5 is pressed and sealed, the entire periphery of the opening 10 can be sealed uniformly. Further, even if the lid 2 is repeatedly opened and closed, the airtightness does not decrease due to wear or deformation of the container body 1 and the lid 2, so that the storage container 100 can be used repeatedly for a long time.

  Next, the opening / closing mechanism of the lid body 2 of this embodiment will be described. The lid body 2 is provided with a top plate portion 21 that covers the opening 10 of the container body 1 and a side plate portion 22 that covers the side surface of the container body 1 continuously from the top plate portion 21. As shown in FIGS. 2 and 4, the rear surface of the lid body 2 is rotatably held by the hinge portion 8 on the rear surface 12 of the container body 1. Since the hinge portion 8 is provided outside the second rib 4, it does not affect the arrangement of the first to fourth ribs that surround the entire periphery of the opening portion 10.

At the center in the lateral direction of the side plate portion 22 on the front surface side of the lid body 2, a fixing portion 9 that engages with the protruding portion 10 b provided on the container body 1 and fixes the lid body 2 is provided. 2, when the opened lid 2 is closed and the opening 10 is closed with the hinge portion 8 as a rotation axis, the fixed portion 9 provided inside the front side plate portion 22 as shown in FIG. Engages with the protrusion 10 b provided on the container body 1. Since the fixing portion 9 engages with the protruding portion 10b provided on the container body 1 and restricts the lid 2 from rotating in the opening direction, the state where the third rib 6 presses the packing 5 is maintained. . When opening the lid body 2, if the end portion P ₃ of the side plate portion 22 is pushed outward, the engagement of the fixing portion 9 is released and the lid body 2 can be opened.

When the user applies a force in a direction to spread the end portion P ₃ of the side plate portion 22 outward in order to open the lid 2, the maximum force connecting the top plate portion 21 and the side plate portion 22 by the force applied to the end portion P _3. deformed portion P ₁ corresponding to the bending point, engagement of the fixing portion 9 is released. The point P _{1 at} which the lid 2 is deformed by the force applied to the end P ₃ (the point at which the lid 2 is deformed when the engagement of the fixing portion 9 is released), the fixing portion P ₂ , and the end P ₃ are: The distance B along the surface of the lid body 2 from P ₂ to P ₃ is 1.4A ≦ B with respect to the distance A along the surface of the lid body 2 from P ₁ to P _{2 in the} vertical direction. It is preferable to set to. By setting the distance B to be 1.4 times the distance A or more, the lid 2 can be opened by releasing the engagement of the fixed portion 9 with a small force, and the wet wiper can be easily taken out during cleaning.

  Moreover, it is preferable that the opening / closing angle of the lid body 2 having the hinge portion 8 as a rotation axis is 90 ° or more and 135 ° or less. When the angle is less than 90 °, it is difficult to take out the wet wiper 101 from the storage container 100. When the angle exceeds 135 °, the storage container 1 may fall over due to the weight of the lid 2.

Second Embodiment
Next, a second embodiment according to the present invention will be described. In 2nd Embodiment, as shown in FIG. 5, it forms so that the inner side of the bottom face 13 of the container main body 1 may become higher in the front surface 11 side rather than the rear surface 12 side. Other points are the same as in the first embodiment. Here, an example is shown in which the inside of the bottom surface 13 is formed in a slope shape so that the thickness of the bottom surface 13 is thicker on the front surface 11 side than on the rear surface 12 side. It is not necessary to limit to the aspect which makes it high on the 11 side. For example, the inner side of the bottom surface 13 may be formed in a stepped shape in which the front surface 11 side becomes higher, or a mountain-shaped convex portion may be provided on the front surface 11 side inside the bottom surface 13.

  It should be noted that the formation of the inner side of the bottom surface 13 of the container main body 1 so as to be higher on the front surface 11 side than the rear surface 12 side as described above is the top surface of the container main body 1 in the first embodiment as shown in FIG. May be combined with an aspect in which the front surface 11 side is set lower than the rear surface 12 side. For example, when the container body 1 is to be deformed into various shapes from a design point of view, the upper surface is different from the first embodiment. May be combined with a mode in which the rear surface 12 side and the front surface 11 side are set to the same height.

  According to the second embodiment, even if the front surface 11 side of the container body 1 is relatively heavier than the rear surface 12 side, and the lid body 2 is greatly opened, the container body 1 is more unlikely to fall than the first embodiment. . The opening / closing angle of the lid body 2 with the hinge portion 8 as the rotation axis can be set to 90 ° or more and 160 ° or less.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to embodiment, A various change is possible in the range which does not deviate from the summary.
