Description

This disclosure relates to a wet tissue storage unit. A wet tissue storage unit that stores wet tissues in a bottle-type container (hereinafter referred to as "bottle container") has the advantage of requiring less frequent replacement (refilling) because it allows long non-woven fabric sheets (wet tissues) to be stored compactly in a roll within the bottle container. Generally, wet wipe containers are manufactured by placing a roll of nonwoven fabric into a bottle container, impregnating it with a liquid, and then sealing the bottle's opening with a film or similar material. The most common sealing method involves heat-welding the film to an adhesive area at the bottle's opening. Patent Document 1 discloses a container with a seal material, comprising a container having a mouth, and a seal material fused to the mouth of the container. The seal material has a sealant layer on the surface fused to the container, and the container has an outermost layer, an intermediate resin layer, and an innermost layer. The outermost and innermost layers contain polyolefin resin and silylated polyolefin, the mouth of the container narrows toward the seal material, and the silylated polyolefin content of the outermost and innermost layers is 1.0 to 20.0% by mass, based on the total mass of the outermost and innermost layers, respectively. Examples of contents stored in this sealed container include viscous condiments such as ketchup, mayonnaise, mustard, and Worcestershire sauce, and viscous detergents such as toothpaste. Patent No. 7469952 This is an external perspective view of a wet tissue storage unit according to one embodiment of the present invention.This is a side view of the bottle container.This is a cross-sectional view taken along the line III-III in Figure 1.This is a top view of the bottle container.This is a plan view of a sealing sticker.This is an explanatory diagram showing an example of the manufacturing process for a wet tissue dispenser. The following describes in detail, based on the drawings, a wet tissue storage unit according to one embodiment of the present invention. Figure 1 is an external perspective view of a wet tissue container according to one embodiment of the present invention. Figure 2 is a side view of the bottle container. Figure 3 is a cross-sectional view taken along the line III-III in Figure 1. Figure 4 is a top view of the bottle container. Figure 5 is a plan view of the seal. Figure 6 is an explanatory diagram showing an example of the manufacturing process of the wet tissue container. In Figures 1 to 3, UP indicates the top, and in Figure 3, IN indicates the radially inward direction. Also, in Figure 3, a cross-section is schematically shown. Also, in Figure 6, the illustration of the male screw is omitted. <Wet tissue storage unit> As shown in Figures 1 to 3, the wet tissue storage unit 10 according to this embodiment comprises a bottle container 20, a roll of wet tissues 1R stored inside the bottle container 20, a sealing seal 30 for sealing the bottle container 20, and a cap 40 that is detachably attached to the bottle container 20. In the following description, the wet tissue storage unit 10 may be referred to as the "product". (Wet wipes) Wet wipe 1 is a nonwoven fabric sheet impregnated with a chemical solution. The material of the nonwoven fabric sheet is not particularly limited, but examples include spunlace nonwoven fabric made by entangling rayon and PET (polyester fiber) with water flow. The nonwoven fabric sheet may or may not have an embossed pattern, but a plain type without an embossed pattern is preferable in order to make it compact when made into a roll 1R. As shown in Figures 3 and 6, the roll body 1R of the wet tissue 1 (hereinafter sometimes simply referred to as "roll body 1R") is made by impregnating a nonwoven fabric sheet, wound into a roll, with a chemical solution. The chemical solution impregnated into the roll body 1R can be any chemical used in general wet tissues 1 (e.g., lotion, alcohol, disinfectant, preservative, etc.). The diameter of the roll body 1R is set to a size that allows it to be inserted into the bottle container 20 through the opening 20a, which will be described later. Perforations (not shown) are provided on the roll body 1R at predetermined intervals in the circumferential direction. (Long volume) The length of the roll 1R of the wet tissue 1 is between 16m and 26m. If the length of the roll 1R is shorter than 16m, the frequency of replacing (replenishing) the roll 1R will increase. On the other hand, if the length of the roll 1R is longer than 26m, the weight of the product will increase, and the sealing seal 30 may peel off unintentionally when the product is dropped, etc. (Bottle container) As shown in Figures 1 to 4, the bottle container 20 is formed in a bottomed cylindrical shape with a circular opening 20a on the upper side (one side in a predetermined direction), and a storage space 21 capable of housing the roll body 1R i
