DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet tissue package in which a wet tissue is stored in a bag, and the wet tissue can be taken out one by one.

[0002]

2. Description of the Related Art In recent years, wet tissues have been widely used for home use and business use, and the consumption thereof has been increasing year by year. A wet tissue is obtained by impregnating a fibrous sheet such as a non-woven fabric with an impregnating agent such as a medicine or a cosmetic, and is used for the purpose of removing stains on hands, disinfecting and wiping a baby's ass.

[0003] Conventionally, there have been known those in which a wet tissue is stored in a box-shaped container and those in which a wet tissue is stored in a bag. The box-shaped container is made of a rigid or semi-rigid plastic molded product, and can store a folded wet tissue or a wet tissue wound in a roll. A wet tissue package using this box-shaped container can be refilled with wet tissue. On the other hand, a wet tissue package using a bag is one in which a folded wet tissue is stored in a bag made of an airtight film, which is convenient to carry and can be disposable. There is.

[0004] A wet tissue package having such a bag storage structure is disclosed in Japanese Patent Publication No. 2-30948. This package is a package in which a wet tissue is stored inside a bag made using an airtight film, and has a structure sealed by a center seal portion and both end seal portions. A cutout portion for forming a wet tissue outlet is provided on the upper surface of the flap-shaped lid made of an airtight film, so as to cover the cutout portion, by an adhesive applied to the back surface of the lid. It is stuck.

[0005]

However, in the above-mentioned conventional package, the lid is fixed with an adhesive force, so that the dust adheres to the adhesive surface while the lid is repeatedly opened and closed several times. There is a drawback that the adhesive strength gradually decreases due to the adhesion of dust and consequently the sealing performance when the lid is closed gradually deteriorates. Also, since the bag is made of a flexible material such as a plastic film, the opening and closing operation of the lid tends to cause wrinkles around the take-out opening, so that the adhesive surface of the lid adheres to the wrinkled film surface. It often happens that the lid is closed. The occurrence of such a situation inevitably leads to a decrease in hermeticity.
In a wet tissue package, the tightness of the lid is important. If the sealing property of the lid is incomplete, the impregnating agent such as the medicine impregnated in the wet tissue and the cosmetic will volatilize, causing a fatal defect.

Further, in this type of flap-shaped lid structure, when the lid is opened, the lid is not held in a horizontally inclined position, but in a direction in which the lid is closed by the elastic force at the hinge portion. When the force is applied, the lid touches the hand during the operation of removing the wet tissue. This not only gives the user an annoying feeling, but also causes contamination of the pressure-sensitive adhesive surface since the pressure-sensitive adhesive surface of the lid touches the hand.

On the other hand, in a package in which a wet tissue is stored in a bag, a collar is attached to a take-out opening provided in the bag, a cap is provided on the collar via a hinge, and the take-out opening is sealed by the cap. Such a structure is disclosed in U.S. Pat. No. 4,185,754. The package shown in the above-mentioned U.S. Patent has an outlet having a size necessary for inserting a finger to pick up a wet tissue. For this reason, the take-out opening has an opening area larger than necessary, and when the cap is opened, the amount of the drug and the cosmetic impregnated in the wet tissue is increased. Therefore, it is difficult for the package of the U.S. Patent to keep the wet tissue in good condition for a long period of time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks. In a wet tissue package having a bag housing structure, the hermeticity is excellent when the lid is closed, and the hermeticity is reduced even when the lid is repeatedly opened and closed. It is an object of the present invention to provide a wet tissue package that can maintain a good state for a long time. Another object of the present invention is to provide a wet tissue package in which the wet tissue can be easily taken out.

[0009]

SUMMARY OF THE INVENTION The present invention provides (1) a bag formed of an airtight film, a lid unit component attached to an opening provided in the bag, and an interior of the bag. A wet tissue package comprising a wet tissue laminate housed in the container, the inside of which is formed to be hermetically sealed by a lid unit component, wherein the lid unit component is provided with a substrate provided with a wet tissue take-out port. And a lid provided on the substrate so that the take-out opening can be opened and closed. The lid has a through-hole penetrating the lid, and is used for opening and closing the through-hole. A wet tissue package provided with a small lid; (2) the wet tissue package described above, wherein the shape of the outlet and the lamination of the wet tissue laminate are formed so as to be able to pop up; ) Is summarized as wet tissue package according.

In the figure, 1 is a bag, 2 is a lid unit component, and a wet tissue laminate 3 is housed inside the bag 1 provided with the lid unit component 2 as shown in FIG. The lid unit component 2 is composed of a substrate 5 provided with a take-out opening 4 for taking out a wet tissue, and a lid 6. A lid for supporting the lid 6 is provided around the take-out opening 4 of the substrate 5. A support portion 7 is provided, and the cover 6 is supported by the cover support portion 7 so as to be able to open and close the take-out opening 4. The cover 6 allows a wet tissue to be taken out and penetrates through the cover. A hole 9 is provided, and a small lid 8 for opening and closing the through hole 9 is provided. The inside of the bag is sealed with the lid closed.

As a material for forming the bag 1, an air-tight film, that is, a film having a property of preventing an impregnating agent such as a medicine or a cosmetic in a wet tissue from seeping out or volatilizing can be used. Used. Examples of such a film include a film made of a plastic such as polyethylene, polypropylene, polyester, polyamide, vinyl chloride, vinylidene chloride, cellophane, and acetate, a laminated film composed of a combination of two or more of these, or a single film thereof, A composite film formed by laminating an aluminum foil on a film may be used. In the case of a laminated film or a composite film, it is preferable that one side of the film is a heat sealable material.

The lid unit component 2 is mounted on the upper surface of the bag body facing the opening 1a provided on the upper surface of the bag body 1. The mutual contact portion between the upper surface of the peripheral portion 5a of the substrate 5 and the lower surface of the peripheral portion of the bag opening 1a (the inner surface side of the bag) in the component 2 is joined by joining means such as heat sealing. The part 2 faces the bag opening 1a and is fixed to the upper surface of the bag 1. In addition to heat sealing, high-frequency sealing, ultrasonic sealing, and bonding with an adhesive can be used as the joining means, but heat sealing is preferable. Although not particularly shown, when attaching the lid unit component 2 to the bag 1, the lower surface of the periphery 5a of the substrate 5 may be joined to the upper surface of the peripheral edge of the bag opening 1a. The lid unit component 2 is preferably joined to the inner surface side of the bag body 1 such that the upper surface of the peripheral portion 5a of the substrate of the component comes into contact with the inner surface side of the bag body because the appearance is good.

The lid unit component 2 is joined to a bag-making film in the process of manufacturing the bag 1. That is, an opening 1a is provided by punching a hole in the film, the component 2 is made to face the opening 1a, and the component 2 is joined and integrated with the film by a joining means such as heat sealing. Using the film obtained by joining the lid unit components, the wet tissue laminate 3 is wrapped with the film, and the center overlapping portion 10a of the film is joined by joining means such as heat sealing. The bag body 1 is formed by joining the end overlap portions 10b and 10c formed on both end sides of the center overlap portion 10a by joining means such as heat sealing.

As shown in FIG. 4, the lid unit component 2 comprises a substrate 5 provided with an outlet 4 for wet tissue and a lid 6 provided on the substrate so that the outlet 4 can be opened and closed. The cover 6 is provided with a through hole 9 penetrating through the cover 6 as shown in FIG. 3 and communicating with the take-out port 4, and the through hole 9 as shown in FIGS. 1 and 2. A small lid 8 for opening and closing is provided. In the lid unit part of the package of the present invention, the mounting structure for allowing the lid to open and close the take-out opening and the mounting structure for allowing the small lid to open and close the through hole are shown in FIGS. An embodiment is shown. The package of the present invention is not limited to this structure.

As shown in FIG. 4, a means for sealing the outlet 4 with the lid 6 is provided with a lid support 7 around the outlet 4 of the substrate 5. Part 7
a, and a fitting portion 6a that can be fitted to the fitting receiving portion 7a is provided on the lid 6. Both the fitting portion 6a and the fitting receiving portion 7a have peripheral walls in the form of protrusions. A fitting state is obtained by the inside of one of the peripheral walls entering the other peripheral wall. In the embodiment shown in FIG. 4, the fitting structure is such that the peripheral wall of the lid supporting portion 7 provided on the substrate 5 enters the inside of the peripheral wall provided around the lid 6. It is not limited to this. Conversely, the structure may be such that the peripheral wall provided on the lid 6 enters the inside of the peripheral wall provided on the lid support 7.

When the lid 6 is closed, the take-out port 4 is sealed by fitting the fitting portion 6a and the fitting receiving portion 7a. The tightness of the outlet 4 can be obtained by forming the fitting state of the fitting portion 6a and the fitting receiving portion 7a densely within a range that does not hinder the opening and closing operation of the lid. The shapes of the fitting part and the fitting receiving part are shown in FIG.
5 may be formed in a ring shape as shown in FIG. 5, or may be formed in other shapes. The lid 6 is provided integrally with the substrate 5 via the hinge 12 and is formed so as to be swingable about the hinge 12 in the rotation direction.

The means for sealing the take-out port 4 with the lid 6 is not limited to the above-mentioned fitting structure, and various structures are used. For example, as shown in FIGS. 6 and 7, the lid 6 slides horizontally above the take-out port 4 and fits into the cover support portion 7 provided on the substrate 5 to seal the take-out port. A fitting structure can be used. In the slide fitting structure, for example, as shown in FIG. 6, a concave groove 6 b having a U-shaped cross section that opens inward is provided at an edge of the lid 6, while the concave groove 6 b is A protrusion 7b fitted to 6b is provided so that the cover 6 wraps around the cover support 7 so that the cover 6 slides on the cover support 7 to open and close the take-out opening 4. Also, although not specifically shown, a concave groove is provided on the side of the lid support portion, and a ridge is provided on the periphery of the lid body to fit into the concave groove, and the lid body is held between the concave grooves of the lid support portion. It may be formed so as to slide fit.

The tightness of the outlet 4 in the lid unit component 2 shown in FIG. 6 depends on the fitting state of the ridge 7b of the lid support portion 7 with the concave groove 6b around the lid 6, and the sealing of the lid 6. It is ensured by the state of contact between the lower surface and the upper surface of the lid support 7. Therefore, the fitting state and the abutting state are formed densely within a range that does not hinder the sliding of the lid 6.

In the package of the present invention, the shape of the lid 6 is
Any shape may be used as long as it is large enough to cover the outlet 4. For example, the lid 6 may be formed in any other shape, such as a rectangular shape as shown in FIG. In the case where the lid 6 is formed in a rectangular shape and slide-fitted to the lid support 7, at least two opposing sides of the lid are formed so as to slide fit into the lid support. Good. Further, the lid 6 may be attached to the lid supporting portion so as to open at least to a position where the take-out opening 4 is exposed so as not to be an obstacle when taking out the wet tissue. In the case of a lid unit component in which the lid slide-fits, the lid is usually formed separately from the substrate, and a stopper is provided so as not to come off the lid support when the lid is opened.

In the lid unit part of the package of the present invention,
It is preferable to provide a locking structure so that the lid is not carelessly opened when the lid is closed. That is, although the usual wet tissue is taken out by opening and closing the small lid, it is necessary to form the lid so as not to open when the small lid is opened and closed. As this locking structure, a normal locking means such as a fitting structure with a projection and a concave portion is used.

The package of the present invention is provided with a through hole 9 penetrating through the take-out port 4 when the cover is closed and a small lid 8 for opening and closing the through hole. The through hole 9 is formed to be smaller than the size of the take-out port 4, and may be large enough to pinch the end of the wet tissue protruding outside from the take-out port 4 with a finger. The shape of the through hole 9 is not limited to the square shape shown in FIG. 3, but may be a circle or any other shape as shown in FIG. 5.

The small lid 8 provided in the through hole 9 of the lid 6
The through-hole 9 is opened and closed so that the outlet can be sealed. Specifically, as shown in FIG. 4, a concave groove-shaped slide support portion 13 is provided inside both ends of the lid 6, and both ends of the small lid 8 are supported by the support portion 13. It can be formed to slide to open and close the through hole 9. Further, as a structure capable of opening and closing the small lid 8, a structure in which the periphery of the small lid 8 is fitted to the receiving portion 14 of the through hole 9 as shown in FIGS. Although not particularly shown, a fitting portion made of a ridge is provided on the side of the small lid, and a receiving portion that fits with the ridge is provided around the through hole of the lid body. You may comprise so that a surrounding receiving part may fit.

In the package of the present invention, the lid unit component is
The mounting structure of the lid to the board, and the mounting structure of the small lid,
These can be arbitrarily combined. That is, FIG.
As shown in FIG. 5, the lid is attached to the substrate by a fitting structure with a peripheral wall, and the small lid is attached to the lid by a slide fitting structure. As shown in FIG. 5, the lid is attached to the substrate. 6 and a structure in which the small lid is attached to the lid by a surrounding wall, FIG.
As shown in the figure, a fitting structure and the like in which both the attachment of the lid to the substrate and the attachment of the small lid to the lid are of a slide fitting type,
Either may be used. Further, as shown in FIG. 7, when both the lid and the small lid have a slide fitting structure, the sliding direction of the small lid may be formed to be orthogonal to the sliding direction of the lid. Further, in the case of a method in which the lid is slid and fitted as in the lid unit parts shown in FIGS. 6 and 7, the sliding direction of the lid 6 is the same as the width direction of the package (the direction orthogonal to the longitudinal direction). It is preferable to attach the lid unit component to the package so that the package unit has a lid. When the lid is attached in this manner, the lid that is pulled out when the lid is opened can be prevented from contacting the upper surface of the package, so that the lid can be smoothly opened and closed.

The material of the lid unit component 2 is preferably a rigid or semi-rigid plastic. As the plastic material, a thermoplastic resin such as polypropylene and polyethylene is used. For example, the substrate 5 and the lid 6 can be integrally formed by injection molding using a thermoplastic resin. In the case of the lid unit component having a structure in which the lid is fitted to the lid support portion by the peripheral wall in the mode shown in FIGS. 4 and 5, even if the substrate 5 and the lid 6 are integrally formed by injection molding. Good. Then, in the case of the embodiment shown in FIG. 4, the small lid 8 is fitted into the slide fitting groove 13 later. In the embodiment shown in FIG. 5, the small lid 8 can also be molded integrally. The material is not limited to plastic, but may be formed of other materials.

The wet tissue laminate 3 is formed by stacking multiple layers of square sheet-shaped wet tissues. The wet tissue laminate may be simply a laminated wet tissue,
It is preferable to stack them so that they can be popped up. A stack of wet tissues that can be popped up is obtained by folding a single wet tissue into three folds, with the ends of the wet tissues engaging with the ends of another folded body. As the wet tissue, a sheet material such as paper, woven fabric, nonwoven fabric, cotton, gauze, foamed sheet or the like made of synthetic fiber or natural fiber is impregnated or applied with an impregnating agent such as a medicine or a cosmetic. Examples of the drug include alcohol for disinfection.

The shape and structure of the take-out opening 4 provided in the substrate 5 of the package of the present invention can be appropriately determined as long as the wet tissue inside the bag can be taken out. The take-out opening 4 is preferably formed to the minimum necessary size for taking out the wet tissue from the viewpoint of the tightness of the package. Since the tissue can be taken out by the small lid 8, volatilization of volatile components can be suppressed well.

The take-out port 4 may be formed as a simple circular or rectangular opening, but is preferably of a shape and structure that allows the wet tissue to be taken out by a pop-up method. Here, the pop-up method is 1
When the second wet tissue is completely removed,
A method in which the upper end of the second wet tissue protrudes above the outlet, and in this case, the wet tissue laminate is also used as a laminate that can be popped up. According to this pop-up method, since the upper end of the wet tissue always projects above the take-out opening, the wet tissue can be easily grasped when the small lid 8 is opened, so that the wet tissue can be easily taken out. is there.

The take-out opening 4 from which the wet tissue can be taken out by the pop-up method is, for example, as shown in FIG.
As shown in FIG. 7, the central passage 4a and the end passages 4b, and the narrow passages 4c having a smaller width than the passages 4a and 4b can be formed. The passages 4a, 4b, 4c communicate with each other to form one outlet. Narrow passage 4
Since c has a narrow passage, it has a function of giving an appropriate resistance to the force for pulling up the wet tissue, thereby enabling pop-up when removing the wet tissue. The shape and structure of the pop-up port that can be popped up are not limited to those shown in FIG. 4, and various modes are possible. For example, the outlet may be configured as a slit hole curved in a wave shape. In short, any shape and structure that can provide an appropriate resistance to the force for pulling up the wet tissue may be used.

In the package of the present invention, the cover 6 is attached to the cover support 7 so as to be at a certain height above the take-out opening 4 of the substrate 5, and as shown in FIG. It is preferable that a space portion 11 is formed between the cover 11 and the upper cover 6. The space portion 11 has a space in which the upper projecting portion of the wet tissue can be substantially stored. Therefore, when the wet tissue can be taken out by the pop-up method, the wet tissue is stored in the space 11, and the lid 6 and the small lid 8 can be smoothly opened and closed.

In order to take out the wet tissue of the package using the lid unit component of the first embodiment of the present invention, first, the lid is rotated about the hinge from the state shown in FIG.
The cover 6 is opened as shown in FIG. At the beginning of use,
Although not shown, a seal for sealing is attached to the surface of the take-out port 4, and the seal is peeled off. Next, the wet tissue 3
a of the wet tissue is pulled out by a finger, and the end of the wet tissue is projected above the outlet 4.
To close the upper portion of the wet tissue in the space 11. Next, as shown in FIG. 3, a finger is put on the knob 15 of the small lid 8 and slid to open the small lid 8. Since the upper part of the wet tissue has protruded there, as shown in FIG. 8, by pulling the wet tissue upward from the through hole 9,
Can be taken out one by one.

If the shape of the outlet 4 of the package and the lamination of the wet tissue laminate 3 can be popped up, one wet tissue 3a is taken out.
The second wet tissue, in which the wet tissue and the end portions are engaged, is pulled together by the end portions and is moved upward. 1
When the second wet tissue 3a completely passes through the outlet 4, the upper end of the second wet tissue passes through the outlet 4, and when the upper end reaches an upper position near the outlet 4, The first wet tissue and the second wet tissue are separated. That is, the narrow passage 4c of the take-out opening 4 causes an appropriate resistance to the force for pulling the wet tissue, and the first and second wet tissues are released because the ends of the wet tissue are released. Separate from each other. As a result, the upper end of the second wet tissue was taken out of the outlet 4.
And stays inside the bag body 1 in a posture protruding upward. Since the upper end portion of the wet tissue protrudes above the take-out opening 4 in this manner, it is convenient to take out the wet tissue next time. In particular, it is very easy to open the small lid and take out the wet tissue from the through hole.

After use, the upper projecting portion of the wet tissue is slightly pushed by a finger to be stored in the space portion 11, and then the small lid 8 is slid to close the through hole 9. The wet tissue does not interfere with the sliding of the small lid, and can be stored smoothly. When the wet tissue is to be taken out again, it can usually be taken out by opening and closing the small lid. When the wet tissue is taken out by opening and closing the small lid, the portion of the wet tissue that is exposed to the outside is much smaller than when the lid is opened, and the volatilization of volatile components is much smaller.

The lid 8 is opened only when starting to use the wet tissue and in the following cases. Even in the case of the pop-up method when using the package, an accident that the upper end of the second wet tissue does not protrude above the outlet 7 and it is difficult to take out the wet tissue from the through hole sometimes occurs. Occur. In such a case, the wet tissue can be easily taken out by opening the lid and exposing the whole taking-out opening. That is, in the present invention, it is only necessary to open the lid and expose the entire take-out opening to the outside only when such an accident occurs or at the start of use of the package.

When the cover 6 is closed, the upper portion of the wet tissue that projects upward is stored in the space 11 between the lower surface of the cover 6 and the outlet 4. Therefore, in the case of the structure in which the space portion 11 is provided, when the lid or the small lid is closed, the projecting portion does not become an obstacle, and no extra load is applied. The space 11 may be any as long as it can substantially accommodate the upper protrusion of the wet tissue. Therefore, the space 11
Does not have to have a space for completely storing the upper protruding portion of the wet tissue without deforming the upper protruding portion, but may have a space capable of deforming and storing the upper protruding portion. .

[0035]

According to the present invention, a wet tissue package is constructed by using a lid unit component comprising a wet tissue outlet and a lid provided on a substrate so that the outlet can be opened and closed. There is no need to use an adhesive for the lid. Therefore, as in the case of using a conventional flap-shaped lid, there is no problem that the sealing property is reduced due to the deterioration of the adhesive strength and there is no problem that wrinkles occur around the outlet, and the sealing property is excellent, and when taking out the wet tissue, The wet tissue can be easily taken out without the hassle of opening and closing like a flap-shaped lid, and both the sealing property and the taking-out property are excellent.

Further, the package of the present invention is provided with a through-hole through which the lid unit component penetrates the lid, and a small lid for opening and closing the through-hole. Because it is excellent in property, it is possible to take out the wet tissue only by opening and closing the small lid to take out the normal wet tissue, and it is only necessary to open the lid only at the first removal or when the wet tissue can not be taken out,
Compared to a conventional package having a cap-shaped lid that opens and closes so that the entire outlet is exposed, the entire outlet is not frequently exposed to the outside, and volatilization of wet tissue cosmetics and chemicals. Is minimized, the wet state can be favorably maintained for a long period of time, and even if an accident occurs, the wet tissue can be easily taken out.
