Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a body fluid absorbent sheet for absorbing menstrual blood during menstrual periods.

[0002]

[Prior Art]

 Conventionally, a device described in Japanese Utility Model Publication No. 59-9615 is known as a body fluid absorbing sheet in which the outer surface of the body fluid absorbing body is individually covered with individual packaging sheets. In this invention, the body fluid absorber is covered with an individual packaging sheet, and the adhesive sheet is coated with the individual packaging sheet without using release paper. Therefore, release paper was unnecessary and the amount of dust generated during use was small.

However, in this invention, the release surface corresponding to the sticking portion is not formed on the individual packaging sheet. Therefore, the sticking portion and the individual packaging sheet are easily firmly fixed, and if the individual packaging sheet is forcibly peeled off, the sticking portion of the body fluid absorber or the individual packaging sheet may be damaged.

In addition, it is desirable that the sticking portion of the body fluid absorbent sheet be formed to have substantially the same length as the body fluid absorbent body in terms of stable sticking property to the shorts. However, in the above-mentioned conventional device, in the folded state, only the outer peripheral surface of the body fluid absorber is covered with the individual packaging sheet, so that the adhesive portion located on the outer peripheral surface side can be covered. However, it is not possible to cover the part that is folded inward. Therefore, when the body fluid absorber is folded in three or more, the adhesive part cannot be formed in the portion that contacts the body fluid absorbing side, and the formed area of the adhesive part is limited to a small size, so that it cannot be attached to shorts. It had the drawback of causing poor adhesion.

Further, as a device proposed for the purpose of eliminating the above-mentioned drawbacks, a method described in Japanese Utility Model Laid-Open No. 2-17127 is known. In the state before use of the body fluid absorbing sheet in this invention, the individual packaging sheet is positioned so as to project outward from at least one end portion in the length direction of the body fluid absorbing body. Then, the body fluid absorber is covered with the individual packaging sheet protruding from the end portion in the length direction.

However, this method has a drawback in that the individual packaging sheet is formed longer than the body fluid absorber, so that the amount of material used for the individual packaging sheet is increased and the cost is increased.

[0007]

[Problems to be solved by the device]

 The present invention is intended to solve the above-mentioned problems, and in the body fluid absorbent sheet, when the outer surface of the body fluid absorbent body is covered with an individual packaging sheet, the entire sticking portion is coated with the individual packaging sheet. By making it possible and obtaining the same effect as covering with release paper, it prevents clogging of water washing and suppresses generation of dust. Even if the individual packaging sheet is formed with the same length as the bodily fluid absorber, and the individual packaging sheet has a smaller dimension in the length direction than the bodily fluid absorber, it is possible to cover the bodily fluid absorber and use less material. It is intended to manufacture a bodily fluid absorption sheet at low cost by utilizing the above.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a body fluid absorbent body with an adhesive applied to the outer surface of the body fluid body absorbent body to form a sticking portion to shorts. Also, the release-treated surface of the heat-sealable individual packaging sheet is formed so that it can be peeled off. From the inside to the inside and fold the folded piece further inside to make a four fold. The body fluid absorber that was folded in four was covered with individual packaging sheets, and the heat-welded parts protruding to both sides of this body fluid absorber were covered. It is made by heating and welding, and individually packaging the bodily fluid absorber with individual packaging sheets.

[0009]

[Action]

 In the body fluid absorbent sheet configured as described above, the body fluid absorbent sheet before use is provided by covering the body fluid absorbent body with the body fluid absorbent side inside in four with individual sheets and projecting on both sides of the body fluid absorbent body. The heat-sealed part of the individual packaging sheet is fixed.

In the present invention, the body fluid absorbing sheet covers the body fluid absorbing body in four-fold with the body fluid absorbing side facing inward by one individual packaging sheet, and is attached on the release treated surface of the individual packaging sheet. The attachment part is coated so that it can be peeled off.

Therefore, as for the body fluid absorbing sheet, the sticking portion can be releasably covered by the individual packaging sheet instead of the release paper without using the release paper. For this reason, the bodily fluid absorption sheet does not require a release paper formed from pulp, and can effectively utilize the wood that is the raw material of pulp to contribute to the prevention of destruction of the natural environment. In addition, since the body fluid absorbent sheet serves as both the body fluid absorbent body packaging and the covering of the sticking portion by one individual packaging sheet, it does not take time and effort to open the body fluid absorbent body, and thus the usability is improved. Can be improved.

In the individual packaging sheet, the sticking portion can be covered with the release-treated surface on the shorts side of the body fluid absorber. For this reason, the individual packaging sheet and the adhesive part do not inadvertently adhere to each other, and the individual packaging sheet and the adhesive part can be easily peeled off during use, so that the body fluid absorber and the individual sheet can be easily separated. Can be prevented.

Further, the body fluid absorbing sheet before use is folded back into four pieces by folding back the body fluid absorbing side from the center part inward, and folding back the folded pieces further inward. For this reason, the individual packaging sheet can cover the entire body fluid absorbing side of the body fluid absorber, and as with conventional products, the individual packaging sheet limits the range of formation of the adhesive portion. It is possible to prevent the gap between the bodily fluid absorber and the shorts by forming the sticking part to a length that is effective.

Further, in the body fluid absorbing sheet, it is preferable that the sticking portion is formed to have the same size as the body fluid absorbing body in order to prevent the shortage with the shorts. In this case, the individualized sheet covering the sticking part is formed with the same length as the body fluid absorber. Also, when it is not necessary to form the adhesive part with the same size as the body fluid absorber, it is not necessary to form the individual packaging sheet with the same length as the body fluid absorber, and it is folded inward in a four-fold state. If the individual packaging sheet is formed until the two shorts contact sides contact each other, the individual packaging sheet can be formed shorter than the body fluid absorber.

When formed in this manner, the bodily fluid absorption sheet enables a hygienic individual packaging of the bodily fluid absorbent body by the individual packaging sheet and good coverage of the sticking portion. In addition, since the body fluid absorbent sheet can be formed to have the same length as the body fluid absorbent body or shorter than the body fluid absorbent body, compared to the conventional body fluid absorbent sheet, the amount of the individual body used sheet is smaller and the amount of dust is smaller. It is effective in protecting the environment from pollution. In addition, because less material is used than conventional products, it is possible to manufacture at lower cost.

Then, in order to open the body fluid absorber, first, the body fluid absorber in the four-fold state is raised outward, and the central portion of the body fluid absorber in the folded state is expanded. Next, deploy the folded piece of the body fluid absorber outward. By the expansion of the body fluid absorber, the heat-welded portions fixed on both sides of the body fluid absorber are peeled off, and the body fluid absorbing side of the body fluid absorber is exposed.

Next, by peeling the release-treated surface of the individual packaging sheet from the sticking part of the body fluid absorber, the sticking part can be fixed to the shorts of the user.
