Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system in which strip-shaped wet tissues perforated at regular intervals in the longitudinal direction are sequentially taken out while being cut and separated through a take-out hole formed in a lid. The present invention relates to a container for wet tissue.

[0002]

2. Description of the Related Art Conventionally, as a container for cutting and separating a perforated strip-shaped wet tissue at regular intervals in the length direction, a notch is provided radially in the center of an elastic lid. There is known a structure in which a wet tissue is taken out from a gap between the cuts. When the wet tissue passes through the cuts, it receives resistance from the thin-walled protruding pieces formed between adjacent cuts, and when the tissue is further raised against this resistance, the perforations are bent by the protruding protruding pieces. , And the wet tissue can be pulled out and cut off in one action.

[0003] The subsequent wet tissue is clamped by the projecting piece with its tip slightly protruding from the lid due to the restoring force of the projecting piece that is going to return to the original state. No need to pull wet tissue from

[0004]

The strength of the wet tissue is not uniform as a whole, but varies from part to part. Therefore, if the resistance due to the protruding pieces becomes too large, the wet tissue may be damaged in portions other than the perforations. The problem of shredding or immersion in the container occurs. Therefore, it is necessary to use a material having a certain degree of flexibility, such as polyethylene or vinyl chloride, as the protruding piece.

However, in the case where a thin-walled protruding piece made of a material having flexibility is formed, the thin-walled protruding piece is repeatedly deformed by pulling out the wet tissue, and plastic deformation occurs during repeated displacement, thereby resulting in resistance to the wet tissue. The force is weakened, cutting failure occurs, and the subsequent wet tissue cannot be held, so that the wet tissue is immersed in the container.

As a solution to such a problem, as disclosed in Japanese Patent Publication No. 55-13245, the resistance required to cut and separate a wet tissue at a perforation without using a protruding piece is used. 2. Description of the Related Art There is known a container in which a round hole having a predetermined diameter that can be provided is formed in a lid.

[0007] The use of the container having the above structure makes it possible to use the container repeatedly. However, if the perforation is to be cut and separated only by the size of the round hole, a container having a considerably small diameter is used. In such containers, it is difficult to first pass the wet tissue through the round hole, and as described above, the tolerance for the variation in the strength of the wet tissue is low, and the wet tissue is not perforated. The problem of shredding at the part and immersion in the container remained.

[0008] In recent years, in particular, due to an increase in environmental awareness, it has been strongly desired to provide a wet tissue container that can be used repeatedly as a refill container. Therefore,
SUMMARY OF THE INVENTION An object of the present invention is to provide a wet tissue container which can be cut and separated at perforations without breakage in the middle and can be used repeatedly.

[0009]

In order to achieve the above object, a container for wet tissue according to the present invention comprises a container body containing a band-shaped wet tissue perforated at regular intervals in a longitudinal direction. And a lid made of a synthetic resin that is detachably fitted to the container body, and a wet tissue extraction hole pierced in the lid, the extraction hole being a wet tissue without cutting and separating perforations. It is characterized by having an opening area enough to take out and a predetermined hole length capable of providing a resistance necessary for cutting and separating perforations formed on the wet tissue.

That is, in the present invention, an opening area is provided in which a perforation, which is considered to be the weakest among the strip-shaped wet tissues, can pass through the wet-tissue extraction hole without being cut and separated. The perforation is cut by frictional resistance of the hole wall by adjusting the length of the extraction hole.

Therefore, if the above configuration is adopted, excessive resistance is not applied to the wet tissue, it is possible to prevent the wet tissue from being cut off in the middle, and it is possible to prevent the wet tissue from being cut off in the middle. C) Since the entire resistance is used, the cutting and separating at the perforation can be reliably performed. The subsequent wet tissue is reliably held in a state in which the distal end slightly protrudes from the outlet hole due to the sufficient resistance of the hole wall without sinking into the container.

[0012] The diameter and length of the take-out hole vary depending on the wet tissue and the material of the container to be used and need to be appropriately adjusted. However, when a general non-woven wet tissue and a polyethylene container are used. Preferably, the diameter of the extraction hole is about 3 to 6 mm and the length is about 2.5 to 4 mm.

Usually, in a container made of a soft resin such as polyethylene, it is necessary to make the thickness of the container about 1 to 2 mm in order to have a certain degree of rigidity. Is not preferred.
Therefore, if the thick part is formed only around the extraction hole and the other part is made the same thickness as a normal soft resin lid, only the extraction hole is drilled in the thick part, and the lid is formed by integral molding. An exit hole can be formed in the body. In addition, the extraction hole does not use a thin protruding piece as in the above-mentioned conventional container, and the extraction hole itself has a simple shape and has a sufficient length. And there is a great advantage that it can be used repeatedly as many times as possible.

However, depending on the material of the lid, the frictional resistance with the wet tissue is small, and it may be necessary to make the length of the extraction hole considerably long in order to provide the resistance necessary for cutting and separating the perforations. is there.

Therefore, in the present invention, a plurality of cuts are formed radially from the extraction hole from the upper end to the lower end of the hole wall, and the ridge formed between adjacent cuts passes through the wet tissue passing therethrough. A structure having a thickness that does not deform due to the stress caused by the stress can be adopted.
Here, the thickness of the ridge portion means the thickness in the length direction of the extraction hole.

With this configuration, the wet tissue introduced into the take-out hole spreads into the cut and receives frictional resistance due to the hole wall and the cut. Therefore, it is possible to provide a greater resistance to the wet tissue as compared with a case in which the removal hole is simply formed, and it is possible to increase the cutting and separating function of the perforation and the function of holding the subsequent wet tissue. it can.

Here, the ridge portion is formed for the purpose of providing resistance to cut and separate perforations of a passing wet tissue, and is provided with a sufficient thickness in the length direction of the takeout hole. This is clearly different from the conventional thin projecting piece in that the projecting ridge itself does not bend or deform when applying resistance.

Therefore, the material for forming the ridge is not limited to a resin having flexibility such as polyethylene as in the case of a thin-walled protruding piece, and a hard synthetic resin such as polystyrene or polycarbonate is used. It is also possible.

The shape of the ridge is inverted U-shaped, inverted V-shaped, M
The shape is not particularly limited, such as a letter shape or an Ω shape, and can be variously changed depending on the shape of the cut, but is preferably formed of a curved surface in order to prevent the wet tissue from being caught. Further, it is preferable to provide a plurality of such members because a large resistance can be given.

The protrusion can be formed so as to connect both ends at the shortest distance from the upper end to the lower end of the extraction hole wall, or may be formed spirally in the hole wall. Forming the ridge in a spiral shape has the advantage that greater resistance can be given to the wet tissue drawn upward.

The extraction hole and the ridge portion described above can be formed in a flat lid. However, in this case, unnecessary friction occurs between the lower edge of the removal hole or the ridge and the wet tissue, and there is a possibility that smooth removal of the wet tissue may be hindered.

Therefore, in the present invention, it is possible to adopt a configuration in which an extraction hole is formed at the top of a dome-shaped bulge provided on the lid. With this configuration, the lifted wet tissue is accurately guided to the extraction hole along the curved surface of the inner surface of the bulging portion.

Further, in the case of forming the ridge, if the lower surface of the ridge is also inclined toward the extraction hole, it is possible to provide a wet tissue container having a smooth extraction feeling.

[0024]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the wet tissue container according to the present invention. The container 1 for wet tissue is made of polyethylene,
The container body 2 includes a lid 3 fitted to an upper portion of the container body 2, and a roll-wound wet tissue 4 is accommodated inside the container body 2. The wet tissue 4 may be, for example, folded in a bellows shape in addition to a roll wound one.

A 3.5 mm diameter take-out hole 5 for taking out the wet tissue 4 is formed in the upper surface of the lid 3, and a cylindrical portion 6 is protruded around the take-out hole 5. A cap 7 that can be fitted to the cylindrical portion 6 is provided at the end of the lid 3.
Are provided continuously, and the inside of the tubular portion 6 can be hermetically sealed, thereby preventing the wet tissue 4 from drying.

Although the thickness of the entire lid 3 is about 1.5 mm, a thick portion 8 having a thickness of about 3 mm is formed around the periphery where the extraction hole 5 is formed. Has become the length. The wet tissue 4 is cut and separated when the perforation passes through the extraction hole 5 due to frictional resistance received from the entire hole wall.

FIG. 2 is a sectional view showing another embodiment of the lid in FIG. This lid 9 has the same structure as the lid of FIG. 1 except for the thick part 8, and has a thickness of 2.5 mm.
A 1.7 mm thick bulged portion 11 is provided at the center of the thick portion 8 and a takeout hole 5 having a diameter of 3.5 mm is drilled at the top. Since the inner surface of the bulging portion 11 is an inclined surface reaching the extraction hole 5, the swelling portion 11 has a function of accurately guiding the wet tissue 4 to the center of the extraction hole 5 as a guide.

The hole wall 12 has a width of 1.5 mm and a depth of 2.
Four 3 mm cuts 13 are formed at equal intervals from the upper end to the lower end of the extraction hole 5, and the adjacent cuts 1 are formed.
A ridge 14 is formed between the three. Ridge 14
Is formed slightly upward, and the wet tissue 4 is smoothly introduced into the extraction hole 5 without being caught by the lower edge of the ridge 14 by the slope formed on the lower surface of the ridge 14. The thickness of the ridge portion 14 is
1 has a thickness of 1.7 mm, and has a sufficient thickness so that it does not deform under the stress caused by passing wet tissue.

The wet tissue 4 introduced into the take-out hole 5 spreads into the cut 13 so that the hole wall 12 and the cut 1
3 receives frictional resistance. Therefore, the lid 9 in the present embodiment has a shorter extraction hole length than the lid body having only the extraction hole 5 as shown in FIG. It becomes possible.

[0030]

As is apparent from the above description, according to the present invention, the present invention has an opening area from which a wet tissue can be taken out without cutting and separating perforations, and is necessary for cutting and separating perforations. By drilling a hole of a length that can provide resistance in the lid, excessive resistance is not applied to the wet tissue, it is possible to prevent the tissue from being cut off in the middle, and to ensure the cutting separation at the perforation Can be done. Further, the subsequent wet tissue is securely held in a state in which the distal end portion slightly protrudes from the outlet hole due to the sufficient resistance of the hole wall without immersing in the container.

Further, if a plurality of cuts are formed in the extraction hole, a greater resistance can be given as compared with a case where the extraction hole is simply formed. At this time, the ridges formed between the adjacent cuts have a thickness that does not deform due to the stress generated by the passing wet tissue, so that the plastic deformation does not occur by pulling out the wet tissue, and it is repeated any number of times. It has a great advantage that it can be used.

Further, by forming an extraction hole at the top of the dome-shaped bulge provided on the lid, the wet tissue can be accurately guided to the center of the extraction hole. Further, if the lower surface of the ridge is slightly inclined upward, the wet tissue can be smoothly introduced into the extraction hole.
