Description

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

  Conventionally, a wet sheet in which a non-woven sheet is impregnated with a liquid component such as water or alcohol (hereinafter referred to as a liquid component) is known as a sanitary product used for cleaning or makeup. The wet sheet storage container for storing the wet sheet wound in a roll shape is, for example, configured such that the container main body can be separated vertically and the upper surface of the upper container main body is a wet sheet having slits and small holes. It is widely known that the takeout portion is formed.

  In the wet sheet, the contained liquid is evaporated by storage conditions such as temperature and humidity, and adheres to the top surface of the container as water droplets. In addition, the wet sheet in a roll-like state moves to the lower part with the passage of time even under appropriate storage conditions, and the liquid fraction in the upper part decreases. That is, it is difficult for the wet sheet in a rolled state to be uniformly impregnated with the liquid component, and tends to be biased downward. When the liquid fraction of the wet sheet is biased, there is a problem that the feeling of use of the portion where the liquid fraction is lowered is lowered. In addition, there is a problem that the storage stability against fungi and molds is reduced.

  With respect to the above problems, by providing a liquid dropping wall at a position around the outlet formed on the upper surface of the upper container body, the wet sheet is squeezed and leaks when the wet sheet is removed from the outlet. A configuration is disclosed in which the liquid component is dropped downward (see, for example, Patent Document 1).

JP, 2009-46179, A

  However, according to the technology described in Patent Document 1 as a result, although the upper part of the roll is re-impregnated with the liquid, the liquid is accumulated only in a part of the upper part of the roll, so the liquid is uniformly dispersed. It can not be impregnated. Therefore, the bias of the liquid fraction of the wet sheet can not be resolved, and the feeling in use and storage stability can not be improved.

  An object of the present invention is to provide a wet sheet storage container capable of suppressing a decrease in usability and storage stability of a wet sheet.

It is a figure which shows the modification of a liquid part guide. It is a figure which shows an example which formed the cover body and the liquid part guide integrally.

  Hereinafter, embodiments of the present invention will be described based on the drawings.

First, the configuration will be described.
A wet sheet storage container (hereinafter, storage container) 100 according to the present embodiment has, for example, an opening 11 as shown in FIG. 1 and FIG. A container body 10 accommodated from the opening 11, and a lid 20 removably attached to the container body 10 so as to open and close the opening 11, and having an extraction portion 21 on the upper surface for extracting the wet sheet P to the outside; It is configured with.
The roll-shaped wet sheets P stored in the storage container 100 have perforations at regular intervals in the length direction, and the wet sheets P having a size separated along the perforations are provided. The user is supposed to use it.

The container body 10 has a substantially cylindrical shape that is substantially constant from the bottom to the vicinity of the upper end, and has an opening 11 that is largely open on the upper surface. Further, on the outer peripheral surface of the upper end portion of the container main body 10, a male screw portion is formed along the circumferential direction.
Since the container main body 10 is cylindrical, it is possible to arrange and store the roll-shaped wet sheet P substantially concentrically. In addition, the wet sheet P is configured to draw out a piece of paper from the center side of the roll.
The container body 10 is integrally formed by injection molding, two-color molding, blow molding, etc. using, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS (Acrylonitrile Butadiene Styrene) resin or the like. Is formed.

The lid 20 has a cylindrical shape with a short length compared to the container body 10, and the upper end side is closed by the top surface portion 22 and the lower end is open. Further, the lid 20 has an outer diameter substantially equal to the outer diameter of the container body 10, and a female screw portion screwed to the male screw portion of the container body 10 is formed on the inner peripheral surface thereof. The lid 20 is detachably attachable to the upper end portion of the container main body 10 by the female screw portion.
Therefore, when the lid 20 is removed from the container main body 10, the inside of the container main body 10 can be filled with the wet sheet P, and when the lid 20 is attached to the container main body 10, the roll of the wet sheet P inside Make it possible to keep the
The lid 20 is integrally formed, for example, by injection molding, two-color molding, blow molding or the like using PE, PP, PET, ABS resin or the like.

A recess 23 is formed in the central portion of the top surface 22 of the lid 20, and a small lid 25 is attached to the top surface 22 so as to fit in the recess 23.
In addition, a cylindrical portion 24 is provided upright at the central portion of the recess 23, and the inside thereof penetrates up and down to form a removal portion 21. At the upper end of the cylindrical portion 24 is formed a flange-like locking portion 24 a that protrudes outward, which allows locking when the small lid 25 is closed.

Here, the takeout unit 21 is for taking out the inner wet sheet P in a state where the lid 20 is attached to the container body 10.
The takeout portion 21 is formed, for example, by cutting in a cross shape in plan view, and appropriately applies sliding resistance to the wet sheet P when the wet sheet P passes the center thereof upward. ing. Thereby, when the wet sheet P is used, the sliding resistance acts on the wet sheet P, and the separation from the perforation is promoted, and the leading end of the next wet sheet P is held in a state of being pinched by the takeout portion 21 As a result, return to the container body 10 is prevented, and the next wet sheet P can be used immediately.
The take-out portion 21 is opened and closed by rotation of the small lid 25 about the Y axis. The small lid 25 is provided with a hinge (not shown) that allows the small lid 25 to be bent along the Y-axis direction in the vicinity of the rear end, and is fitted in the recess 23 to close the takeout part 21 It is possible to stand up from the state and turn the takeout unit 21 to the open state. The small lid 25 is normally kept in the closed state except that it is opened when the wet sheet P is taken out.

Inside the container main body 10, a liquid component guide 30 is provided detachably along the entire circumference of the inner peripheral surface above the roll-shaped wet sheet P and drops the liquid component downward.
As shown in FIG. 1 and FIG. 3, the liquid component guide 30 has a funnel shape which becomes thinner toward the lower end (open end) 32 whose center is open, and the upper end 31 and the lower end 32 are circular. It is open. The outer diameter of the upper end portion 31 of the liquid component guide 30 is slightly shorter than the outer diameter of the container main body 10, and the liquid content guide 30 is fitted and held at the upper end portion of the container main body 10. As shown in FIG. 3, in the liquid component guide 30, the outer diameter (maximum length) d1 of the lower end portion 32 is longer than the core diameter d2 which is the diameter of the core portion P2 of the roll-shaped wet sheet P in the initial state. And it is shorter than the winding diameter d3 which is the diameter of the outer edge part P3 (d2 <d1 <d3). That is, the lower portion 32 of the liquid component guide 30 is positioned outside the core P2 of the roll-shaped wet sheet P in the initial state and inside the outer edge P3.
The liquid component guide 30 is integrally formed by injection molding, two-color molding, blow molding, or the like using a hard material such as PE, PP, or PET, for example. For example, instead of using a hard material, a soft material such as rubber such as silicone rubber, or thermoplastic elastomer such as styrene-based, olefin-based, vinyl chloride-based, polyester-based, polyurethane-based, or nylon-based elastomer may be used. You may
The liquid component guide 30 is more preferable because the liquid component moves smoothly when the surface is water-repellent treated.

Next, the operation will be described.
In the present embodiment, the roll-shaped wet sheet P is placed in the container body 10, and after the liquid component guide 30 is mounted from above, the container body 10 and the lid 20 are screwed together. Inside, the roll-shaped wet sheet P is in a state of being positioned below the liquid component guide 30.
The roll-shaped wet sheet P is uniformly impregnated with the liquid at the beginning of use, but if the storage conditions change or time passes, the contained liquid evaporates or the liquid becomes lower As a result, the liquid fraction of the roll-shaped wet sheet P is biased.
As shown in FIG. 4, the liquid that has evaporated and attached to the top surface 22 of the lid 20 as water droplets is dropped on the upper surface of the roll-shaped wet sheet P along the inner surface of the liquid guide 30. Further, after moving to the lower part, the liquid portion evaporated as water droplets adhering to the outer surface of the liquid guide 30 is transferred to the outer surface of the liquid guide 30 and rolled as shown in FIG. Dropped on top. That is, the liquid component is dropped on the upper side (upper surface) of the roll-shaped wet sheet P from which the liquid component is further lost, and the liquid component is uniformly impregnated.
After that, even if the liquid fraction of the roll-shaped wet sheet P is uneven, the liquid is similarly dropped onto the upper surface of the roll-shaped wet sheet P, so the liquid is uniformly impregnated. It can be done.

As described above, the storage container 100 according to the present embodiment is provided along the entire circumference of the inner peripheral surface above the roll-shaped wet sheet P in the container main body 10, and is a liquid that drops the liquid component downward. A minute guide 30 is provided. The liquid component guide 30 has an open end (lower end 32) opened at the center, and the open end is outside the core P2 of the roll-shaped wet sheet P in the initial state and more than the outer edge P3. It is located inside.
Therefore, according to the storage container 100 according to the present embodiment, the liquid component condensed on the top surface of the container or the liquid component squeezed when the wet sheet P is pulled out is re-impregnated on the upper part of the roll to make it uniform. Since it is possible to impregnate the liquid component, it is possible to suppress a drop in the feeling of use of the wet sheet P. In addition, it is possible to suppress the decrease in storage stability of the wet sheet P against bacteria and mold.

  As mentioned above, although it explained concretely based on the embodiment concerning the present invention, the present invention is not limited to the above-mentioned embodiment, and can be changed in the range which does not deviate from the gist.

For example, in the above embodiment, the liquid component guide 30 is detachably installed inside the container body 10, but the invention is not limited to this. That is, the container body 10 and the liquid component guide 30 may be integrally formed. In this case, the liquid component guide 30 is formed using a soft material, and the slit 33 is formed from the lower end portion 32 (see FIG. 5A) or divided into two (see FIG. 5B). And the opening of the lower end portion 32 of the liquid component guide 30 can be expanded. This is because when the container body 10 and the liquid component guide 30 are integrally formed, the take-up diameter d3 of the roll-shaped wet sheet P is greater than the maximum length (outside diameter) d1 of the lower end portion 32 of the liquid component guide 30. Because the length is also long, the roll-shaped wet sheet P can be accommodated by making the maximum length d1 expandable to the winding diameter d3 or more.
As described above, the liquid component guide 30 is formed integrally with the container body 10, and the lower end portion 32 is formed so as to be able to expand in diameter when the roll-shaped wet sheet P is stored, whereby the roll-shaped wet is formed. The sheet P can be easily stored, and the time and effort required for the storage operation can be reduced.

Also, for example, as shown in FIG. 6A, a plurality of grooves 34 may be formed on the lower end portion 32 side of the liquid component guide 30. Further, as shown in FIG. 6B, a plurality of pleated grooves 35 may be formed from the upper end portion 31 side of the liquid component guide 30 toward the lower end portion 32. Further, as shown in FIG. 6C, a spiral groove 36 may be formed from the upper end 31 to the lower end 32.
According to the example shown in FIG. 6A to FIG. 6C, the dropped liquid portion is concentrated in the groove portion and is likely to be a water drop, so it is easy to be dropped on the upper surface of the roll-shaped wet sheet P. be able to.
Further, for example, as shown in FIG. 6D, the lower end portion 32A of the liquid component guide 30 may be formed in a mountain-valley shape, or may be formed in a wave shape.
According to the example shown in FIG. 6 (D), the dropped liquid is concentrated at the tip of the lower end portion 32A and becomes a water drop easily, so it can be easily dropped on the upper surface of the roll-shaped wet sheet P. . In the example shown in FIG. 6 (D), it is preferable to form at least three or more peaks and valleys or waves.

Further, instead of installing the liquid component guide 30 inside the container main body 10, the lid 20 and the liquid component guide 30 may be integrally formed. In this case, as shown in FIG. 7, by making the shape of the top surface 22 of the lid 20 curved, it is possible to smoothly guide the water droplets attached to the top surface 22 of the lid 20 to the liquid guide 30. it can. The same effect can be obtained even when the configuration in which the shape of the top surface portion 22 is curved is applied to the configuration in which the liquid component guide 30 is installed inside the container main body 10.
As described above, by making the shape of the top surface portion 22 of the lid 20 curved, it is possible to smoothly guide the water droplets attached to the top surface 22 of the lid 20 to the liquid guide 30, and the efficiency is improved. The liquid fraction of the wet sheet P can be increased by dropping the liquid fraction. Further, by forming the liquid component guide 30 integrally with the lid 20, attachment and detachment of the lid 20 and attachment and detachment of the liquid component guide 30 can be performed simultaneously, and it takes time and effort for refilling the wet sheet P. Can be reduced.

Further, when the lid 20 and the liquid component guide 30 are integrally formed, the distance between the lower end portion 32 of the liquid component guide 30 and the upper surface of the roll-shaped wet sheet P can be closely approached to reliably guide the liquid component. In order to set it, it is preferable to make the lower end part 32 of the liquid component guide 30 project below the lower end part of the lid 20. In this case, since the distance between the extraction portion 21 of the lid 20 and the lower end portion 32 of the liquid guide 30 is long, there is a problem that it is difficult for the user to hold the wet sheet P in the extraction portion 21. Therefore, the liquid component guide 30 is formed using a soft material, and as shown in FIG. 7, it is formed in a bellows shape so as to be foldable in the take-out direction of the roll-shaped wet sheet P. By doing so, when holding the wet sheet P in the takeout portion 21, the liquid component guide 30 can be folded to make the distance between the takeout portion 21 and the lower end portion 32 closer. The inner angle θ1 and the outer angle θ2 of the bellows-shaped portion are preferably 100 ° or more, and more preferably 125 ° or more so that the liquid component smoothly moves downward.
As described above, by forming the liquid component guide 30 in the bellows shape so as to be foldable in the takeout direction of the roll-shaped wet sheet P, the distance between the takeout portion 21 and the lower end portion 32 can be made closer. The sheet P can be easily held by the takeout unit 21.

  Moreover, in the said embodiment, although the lower end part 32 of the liquid part guide 30 is opening circularly, it is not limited to this. That is, as long as the core diameter d2 of the roll <the outer diameter d1 of the lower end 32 <the roll diameter d3 of the roll is satisfied, any shape may be used. You may make it open in shape. In addition, when opening in elliptical shape or polygonal shape, let the outer diameter d1 of the lower end part 32 be the largest length of an opening part.

  In addition, the detailed configuration of the storage container 100 can be appropriately changed without departing from the scope of the present invention.
