Description

  The present invention relates to a toothpaste sheet that is attached to a finger and used for cleaning and massaging teeth and gums.

  Toothpaste sheets are often used for cleaning the oral cavity of infants and those who need care. This toothpaste sheet is used by fitting a finger between two pieces of fabric that are pasted together and formed into a bag shape. Is what you do.

  However, the conventional toothpaste sheet as described above is simply formed in a bag shape and is easily detached from the finger, and the removed toothpaste sheet is very dangerous because it may cause suffocation if accidentally swallowed. In addition, the product that does not fit the finger is displaced from the finger and is difficult to use, resulting in a problem that the teeth cannot be brushed cleanly.

  In order to solve such a problem, for example, in Patent Document 1, a sheath-like finger sack portion for inserting a finger to rub the target portion and a locking portion connected to the finger sack portion are formed. A finger suck type rubbing tool is disclosed in which a locking opening for inserting and locking a finger different from the finger inserted into the finger sucking portion is provided in the locking portion.

  According to this technique, the finger sack type rubbing tool is provided with a locking port, so that it does not move or fall out of the finger during use. However, it is necessary to prepare products with different dimensions and positions according to the size of hands and fingers, and there is a problem that the manufacturing cost increases due to the increase in the number of types of products, and the demand is low depending on the seller. There is a problem that the product of the size is not handled and it is difficult for the customer to purchase.

  As a technique for solving such a problem, for example, Patent Literature 2 includes a main fabric that is long in the front and rear direction and a subordinate fabric that matches the front end shape of the main fabric, and the subordinate fabric is stacked on the front end portion of the main fabric. In addition, by binding the outer edges of both fabrics excluding the rear end of the subordinate fabric, a bag-like sheath with a rear end opening for inserting fingers is formed, and the main fabric closer to the rear than the sheath Oral cleaning provided with a slit in the central part in the left-right direction for a long time in the front-rear direction to hang a plurality of fingers other than the fingers inserted in the sheath part to prevent the sheath part from falling off the fingers A tool is disclosed.

  According to this technique, the oral cleaning tool can be attached to the fingers regardless of the size of the hands and fingers, and can be mass-produced at low cost. However, since the method of use is complicated and difficult to understand and can only be used on one side, there has been a problem that several oral cleaning tools are required for each use.

JP 2000-126225 A JP 2005-334065 A

  The present invention has been made in view of such conventional problems. One of the objects of the present invention is a toothpaste that is easy to understand how to use, does not increase the manufacturing cost, and fits the finger firmly during use, and does not slip or come off regardless of the size of the user's finger. To provide a sheet.

Means for Solving the Problems and Effects of the Invention

  According to the toothpaste sheet according to the first aspect of the present invention, the toothpaste sheet has a finger sack-shaped insertion portion formed by fusing a sheet-like base material, and is fitted into a finger via the insertion portion so that the oral cavity is filled. A toothpaste sheet to be cleaned, in which an inner sheet and an outer sheet laminated on the outer side of the inner sheet are integrated through a joint, and the insertion portion is formed between the two integrated inner sheets The non-woven sheet, and the non-woven sheet is fused so as to spread in the direction in which the finger is pulled out at a symmetrical position across the finger inserted in the insertion part, and the fingertip side tip and the finger are in contact with each other In this state, when a force is applied in the direction in which the finger is pulled out from the insertion portion, the non-woven fabric in the direction in which the finger inserted from the insertion portion is pulled out, and a fusion portion that applies a force so that the finger is not pulled out The finger that the sheet is inserted Comprising a stretched clamping portion to be clamped by the finger, the joint between said inner sheet the outer sheet may be provided on the clamping unit. With the above configuration, by providing the fusion part, when the user moves the finger inserted in the insertion part in the direction of pulling out, the fusion part is caught on the finger and the toothpaste sheet is prevented from coming off the finger. Can do.

  Thereby, a toothpaste sheet can be hold | maintained more stably and the possibility that a toothpaste sheet may be swallowed accidentally and suffocate can be reduced. Moreover, since the usage method can be understood sensuously from the shape of the toothpaste sheet and the usage method is simple, it can be used easily even when it is used for the first time. Furthermore, since the fusion part can be formed in the same process as the process of fusing the insertion part, the number of manufacturing processes does not increase, and the cost is not increased while the function is improved.

  In addition, since the clamping part is provided so that it can be pressed at least with the thumb or middle finger, even if a strong force is applied, the toothpaste sheet does not come off, and the inner sheet and the outer sheet are joined in the vicinity of the opening end. Therefore, you can't put your finger between the inner sheet and the outer sheet by mistake.

Furthermore, according to the toothpaste sheet according to the second aspect of the present invention, the inner sheet includes at least one of polypropylene, polyethylene, polyester, nylon, and acrylic, and has a basis weight of 15 g / m ² or more and 30 g. / M ² or less nonwoven fabric, and the outer sheet includes at least one of rayon, cotton, polyester, and pulp, and has a basis weight of 30 g / m ² or more and 100 g / m ² or less. The part can be configured to be 20 mm to 80 mm in length. With the above configuration, the outer sheet having a high water retention rate can well contain a dentifrice, and the inner sheet having a low water retention rate can be made difficult to contain a drug because it can be in contact with the finger. Can be reduced and the feel can be improved.

(Configuration of toothpaste sheet 1)

  The block diagram which shows Example 1 of the toothpaste sheet 1 which concerns on this invention is shown in FIG. As shown in this figure, a toothpaste sheet 1 according to Example 1 includes a nonwoven fabric sheet 2 that forms an insertion portion 4 and a plurality of C-shaped fusion welded so that the insertion portion 4 is formed. Nipping part that is fitted in both the front side and the back side and is stretched so that both sides have the same length in the direction of pulling out the fingers so as to be clamped by a finger different from the finger inserted into the insertion part 4 5 as a main part. The fusion part 3 is not limited to the U-shape, and may take various forms such as being joined linearly along the outer shape of the toothpaste sheet 1 or joined in a semicircular shape. It includes both a fusion part for forming the part 4 and a fusion part for functioning as a stopper that makes it difficult to pull out the finger. Here, a cross-sectional shape will be described as an example, and various forms will be described later as modified examples.

  The non-woven fabric sheet 2 is impregnated with a dentifrice, and is laminated on the inner surface of the outer surface sheet 21 with two layers for wiping off dirt in the oral cavity, and two layers for preventing adhesion of the dentifrice to the finger. The inner sheet 22 is composed of four layers, and the outer sheet 21 and the inner sheet 22 are fused and integrated through the joint 6 so that each of them is symmetrical with the inserted finger interposed therebetween. It is arranged. In the present specification, for convenience, one of the two sets of integrated sheets is referred to as a first sheet and the other is referred to as a second sheet. The nonwoven fabric sheet 2 is not limited to the four-layer structure as described above, and may have a two-layer structure including only the outer sheet 21, and a functional sheet or the like may be added to the outer sheet 21 and the inner sheet 22. A multilayer structure may also be used.

FIG. 2 is a schematic front view showing Example 1 of the toothpaste sheet 1 according to the present invention, FIG. 3 is a schematic cross-sectional view taken along line AA ′ in FIG. 2, and FIG. FIG. 4 is a diagram showing the above, and FIG. 5 is a schematic cross-sectional view taken along the line BB ′ in FIG. Hereinafter, based on FIGS. 1-5, the structure of the toothpaste sheet | seat 1 is demonstrated concretely.
(Outer surface sheet 21)

  The outer surface sheet 21 is a finger-shaped nonwoven fabric sheet 2 that forms the outer surface of the toothpaste sheet 1 and is impregnated with a dentifrice. It is a member used for cleaning and massaging in the oral cavity due to the dentifrice and the unevenness of the sheet surface. The pinching portion 5 of the outer surface sheet 21 is a member that is pinched by fingers other than the finger inserted so that the toothpaste sheet 1 does not come off the finger.

  As shown in FIGS. 1 to 5, the outer sheet 21 includes a first outer sheet 211 and a second outer sheet 212 having the same shape, and is cut into a finger shape with a total length of 120 mm and a width of 50 mm that becomes slightly narrower toward the tip. The nonwoven fabric sheet 2 contains at least one of rayon, cotton, polyester, pulp and the like. The outer sheet 21 is preferably a spunbond nonwoven fabric, a hydroentangled nonwoven fabric, or a thermal bond nonwoven fabric in order to prevent unintended chemical substances from entering the user's body. Moreover, since the outer surface sheet 21 can easily remove dirt if it has irregularities on the surface, a mesh material is suitable. The outer sheet 21 may be provided with irregularities on the surface by embossing or the like, and may be provided with a plurality of through holes by hole processing.

  The first outer sheet 211 and the second outer sheet 212 are laminated outside a first inner sheet 221 and a second inner sheet 222, which will be described later, and are fused together with the inner sheet 22 in the shape of a finger to insert the insertion portion 4. The first inner sheet 221 and the second inner sheet 222 are not fused and formed on the palm side and back of the hand when the toothpaste sheet 1 is mounted. Dividing and forming the pinching portion 5 that is pinched by fingers other than the inserted finger so that the toothpaste sheet 1 does not come off the finger.

  The fibers of the outer sheet 21 are subjected to a hydrophilic treatment so that the water retention rate is 600 wt% or more and 1500 wt% or less. When the water retention rate of the outer surface sheet 21 is less than 600 wt%, the amount of the dentifrice impregnated decreases and the cleaning effect in the oral cavity decreases. The upper limit value of the water retention rate is assumed to be a limit value of the amount of water that can be absorbed by the nonwoven fabric itself.

  As a method for hydrophilic treatment of the fiber, it can be carried out by a method generally employed for making the nonwoven fabric fiber of a paper diaper or a sanitary napkin hydrophilic. For example, it is a long-fiber nonwoven fabric made of thermoplastic fibers, and the thermoplastic fiber constituting the long-fiber nonwoven fabric contains a hydrophilic agent in an amount of 0.05 to 5.0 wt% with respect to the fiber weight, and a hydrophilized oil agent There is a hydrophilic long-fiber non-woven fabric in which 0.1 to 2.0 wt% is attached to the weight of the long-fiber non-woven fabric (see JP-A-2003-201670). In the above-described embodiment, the hydrophilic treatment of the outer sheet 21 is performed. However, for example, if the water retention rate of the nonwoven fabric is within the above-described range, the hydrophilic treatment is not necessary.

The basis weight of the outer surface sheet 21 is preferably 30 g / m ² or more and 100 g / m ² or less. This is because, when the basis weight of the outer surface sheet 21 becomes thinner than 30 g / m ^{2, the} amount of the dentifrice impregnated decreases as the water retention amount decreases. Further, the outer sheet 21 increases the removal rate of plaque and the like per unit area of the nonwoven fabric sheet 2 by increasing the amount of the dentifrice impregnated as the water absorption amount and the water retention amount increase. However, if the basis weight exceeds 100 g / m ² , the thickness of the outer surface sheet 21 becomes thick, which makes the touch when it fits in the hand become worse and the fine work cannot be performed and the plaque is removed. This is because it becomes difficult.
(Inner sheet 22)

  The inner sheet 22 is a finger-shaped non-woven sheet 2 that forms the inner surface of the toothpaste sheet 1 and prevents the toothpaste, saliva, etc. impregnated in the outer sheet 21 from adhering to the finger, and the laminated outer sheet 21 and inner sheet 22 is a member to which 22 is bonded.

  As shown in FIGS. 1 to 5, the inner sheet 22 is a 100 wt% polypropylene non-woven sheet 2 composed of a first inner sheet 221 and a second inner sheet 222 having the same shape as the outer sheet 21. As the inner surface sheet 22, a nonwoven fabric sheet 2 containing at least one of polypropylene, polyethylene, polyester, nylon, and acrylic can be used in addition to the nonwoven fabric sheet 2 of 100 wt% polypropylene. The inner sheet 22 is preferably a spunbond nonwoven fabric, a hydroentangled nonwoven fabric, or a thermal bond nonwoven fabric in order to prevent unintended chemical substances from entering the body of the user.

  The first inner surface sheet 221 and the second inner surface sheet 222 are laminated inside the first outer surface sheet 211 and the second outer surface sheet 212, and are fused integrally with the outer surface sheet 21 in the shape of a finger to form the insertion portion 4. In addition, the finger inserted from the insertion portion 4 is stretched in the direction in which the finger is pulled out, the first inner surface sheet 221 and the second inner surface sheet 222 are not fused, and are separated into the palm side and the back side of the hand when the toothpaste sheet 1 is mounted. A pinching portion 5 is formed to be pinched by a finger other than the inserted finger so that the toothpaste sheet 1 does not come off the finger.

  The fibers of the inner surface sheet 22 are subjected to water repellent (hydrophobic) treatment. As a method for water-repellent treatment of the fibers, a generally adopted method may be used. For example, by depositing an inorganic oxide vapor-deposited film on one side of a fiber material by chemical vapor deposition, various characteristics such as water absorption, water retention, texture, and air permeability that are characteristic of the fiber material are impaired. In addition, a water-repellent effect can be imparted to one side of the fiber material (see JP 2012-246586 A). In the above-described embodiment, the water repellent treatment of the inner surface sheet 22 is performed. However, for example, the water repellent treatment is not necessary if the water retention rate of the nonwoven fabric is within the aforementioned range.

  The water retention rate of the inner surface sheet 22 is preferably 0 wt% or more and 400 wt% or less. This is because if the water retention rate greatly exceeds 400 wt%, the hand gets wet or gets dirty with dentifrice or saliva.

The basis weight of the inner surface sheet 22 is preferably 15 g / m ² or more and 30 g / m ² or less. If the basis weight is less than 15 g / m ² , the toothpaste and saliva impregnated in the outer sheet 21 pass through the inner sheet 22 from the outer sheet 21 and touch the hand to make it sticky. On the other hand, if the basis weight exceeds 30 g / m ² , the inner surface sheet 22 becomes stiff and unpleasant to the touch.

Instead of the inner sheet 22, the outer sheet 21 may serve as a member to be bonded.
(Fusion part 3)

  The fusion part 3 adheres the outer sheet 21 and the inner sheet 22, and when the finger is inserted into the insertion part 4, by guiding the finger to be inserted in the distal direction of the toothpaste sheet 1, When a force is applied in a direction in which the finger is pulled out from the insertion portion 4 in a state where the finger is easy to put in and the fingertip side tip of the fusion portion 3 is in contact with the finger, the finger is the fingertip of the fusion portion 3 It is a member that applies a force so that the inserted finger does not come out of the toothpaste sheet 1 by being caught on the side tip.

  As shown in FIG. 1 to FIG. 5, the first outer surface sheet 211 is formed so that the fusion part 3 spreads in the left-right symmetrical position across the finger inserted in the insertion part 4 in the direction in which the finger is pulled out. The nonwoven fabric sheet 2 laminated | stacked in order of the 1st inner surface sheet | seat 221, the 2nd inner surface sheet | seat 222, and the 2nd outer surface sheet | seat 212 is fuse | melted and formed in a square shape. The fusion part 3 provided such that the fingertip side tip of the fusion part 3 is positioned in the vicinity of the joint of the inserted finger (finger base side) is subjected to a force in the direction in which the finger is pulled out from the insertion part 4. When the fingertip side tip of the fusion part 3 is caught by the joint, the force acts to prevent the finger from moving in the direction in which the finger is pulled out, and it is possible to suitably prevent the finger from coming off the toothpaste sheet 1. it can.

  For example, assuming an average adult, the fusion part 3 is located at a position of about 25 mm to 40 mm near the first joint or a position of about 45 mm to 60 mm near the second joint from the distal end of the insertion part 4. It is preferable that at least one is provided in each.

  As shown in FIG. 1 to FIG. 2, a plurality of fusion parts 3 can serve as the insertion part 4 by being provided in a plurality along the fingers.

It is sufficient that the fusing method has a sealing strength and a sealing temperature so that the inner sheet 22 and the outer sheet 21 do not come off during use. For example, supplying a fiber sheet that can be heat-sealed between a pair of rolls on which at least one outer peripheral surface protrudes a seal projection of a predetermined pattern, heating and pressurizing the fiber sheet by the seal projection, There is a method of heat-sealing to form a fused portion 3 corresponding to the pattern of the seal protrusions on the fiber sheet (see Japanese Patent Application Laid-Open No. 2007-245458).
(Insertion part 4)

  The insertion part 4 is a member for inserting a finger.

  As shown in FIGS. 1 to 5, the insertion portion 4 is formed by fusing a first inner sheet 221 and a second inner sheet 222 into a bag shape. The width of the insertion portion 4 is 20 mm or more and 50 mm or less, and preferably about 45 mm, which is easy to insert even for a user with a thick finger.

In the case where the fusion part 3 and the insertion part 4 are formed separately, the fusion part 3 is provided inside the insertion part 4.
(Nipping part 5)

  The clamping part 5 is a member for holding and holding the toothbrushing sheet 1 from the inserted finger.

  As shown in FIGS. 1 to 5, the sandwiching portion 5 is a region extended from the insertion portion 4 of the outer sheet 21 and the inner sheet 22. In other words, the clamping part 5 consists of the outer surface sheet 21 and the inner surface sheet 22 and is a part where the inner surface sheets 22 are not bonded to each other. The length is preferably 20 mm or more and 80 mm or less. This is because if it is shorter than 20 mm, it will be difficult to hold, and if it is longer than 80 mm, it will protrude from the hand during use and will be in the way.

  The sandwiching portion 5 includes a first outer surface sheet 211 and a first inner surface sheet 221 that are heat-sealed at the joining portion 6 along the end portion to form a first sheet. The second outer sheet 212 is heat-sealed at the joint 6 to form a second sheet. It is possible to prevent a finger from being mistakenly inserted between the outer sheet 21 and the inner sheet 22, and the insertion portion 4 between the first sheet and the second sheet can be easily opened and sandwiched. This is because it can be easily done. Here, the first outer sheet 211 and the first inner sheet 221 are not limited to heat fusion, and may be joined by, for example, ultrasonic fusion. Moreover, although the junction part 6 is joined linearly along the edge part of the clamping part 5, it is not limited to this, For example, you may join to the spot form in several places. In other words, the first outer sheet and the first inner sheet are joined at least in the vicinity of the open end formed between the outer sheet and the inner sheet so that a finger can easily be mistakenly inserted between the outer sheet and the inner sheet. It is good to do so. Note that the open end means the end of the opening of the insertion portion 4 when the toothpaste sheet 1 does not have the gripping portion 5, and the end of the opening of the gripping portion 5 when having the gripping portion 5. Part.

In addition, although the outer surface sheet 21 and the inner surface sheet 22 both explained the case where the role of the clamping part 5 was demonstrated in the present Example, only the outer surface sheet 21 or only the inner surface sheet 22 may play the role of the clamping part 5, and it clamps When only one sheet plays the role of the part 5, the outer sheet 21 and the inner sheet 22 may have different shapes.
(Toothpaste)

  The dentifrice is a member for impregnating the outer surface sheet 21 to easily remove plaque, to give a refreshing feeling to the user, and to impart an antiseptic effect to the sheet.

  For example, dentifrices are water (base material), PG (humectant), PEG-60 hydrogenated castor oil (solubilizer), methyl paraben (preservative), ethyl paraben (preservative), butyl paraben (preservative). , Betaine (humectant), glycerin (humectant), hyaluronic acid Na (humectant), glycyrrhizic acid 2K (flavoring agent), sucralose (sweetener), saccharin Na (sweetener), benzoic acid Na (preservative), Those containing cetylpyridinium chloride (preservative), citric acid (pH adjuster), and sodium citrate (pH adjuster) can be used.

However, the dentifrice is not limited to the above-described ones, and can contain chemical components adjusted to the intended purpose.
(Modification)

Moreover, it is a schematic front view which shows the toothpaste sheet | seat 1 which concerns on this invention, Comprising: Example 2 in FIG. 6A, Example 3 in FIG. 6B, Example 4 in FIG. 6C, Example 5 in FIG. Example 6 is shown in FIG. 6E, Example 7 is shown in FIG. 6F, Example 8 is shown in FIG. 6G, and Example 9 is shown in FIG. 6H. As shown in these drawings, the toothpaste sheet 1 according to the present invention is not limited to the toothpaste sheet 1 described in the first embodiment. In particular, as shown in FIG. 6A, the first sheet and the second sheet can be strongly bonded to each other by fusing them in such a shape that the end points of the C-shaped fusion part 3 are connected to each other. Moreover, as shown in FIGS. 6B to 6E, the insertion portion 4 may not be formed by the fusion portion 3, and the fusion portion 3 only needs to be formed inside the insertion portion 4. Furthermore, as shown in FIGS. 6E to 6G, the fusion part 3 may be further provided inside the fusion part 3. It is also possible to weaken the coupling of the inner fusion part 3 and to release the coupling of the inner fusion part 3 when inserting a thick finger. Furthermore, as shown to FIG. 6H, the melt | fusion part 3 may be a semicircle shape. By adopting a semicircular shape in this way, the lower half of the semicircle in FIG. 6H has a shape close to a C shape, and the effect that the finger is difficult to be pulled out is obtained, and the smooth curved portion is in contact with the finger. Therefore, it is possible to give a smooth feeling to the user without feeling uncomfortable or uncomfortable when inserting or pulling out the finger.
(Manufacturing procedure)

  First, a hydrophilic first outer sheet 211 and a second outer sheet 212, and a hydrophobic or water-repellent first inner sheet 221 and a second inner sheet 222 are prepared. The prepared nonwoven fabric sheet 2 is laminated in the order of the first outer sheet 211, the first inner sheet 221, the second inner sheet 222, and the second outer sheet 212.

  Next, the first outer sheet 211 and the first inner sheet 221 are heat-sealed by the sandwiching unit 5 to form the first sheet, and the second inner sheet 222 and the second outer sheet 212 are sandwiched together. 5 is heat-sealed to form a second sheet.

  Further, the first sheet and the second sheet are heat-sealed so that the fused portion 3 and the finger-shaped insertion portion 4 are formed, and cut into a finger shape by a roll cutter.

Finally, the cut toothpaste sheet 1 is packed in a bag, a toothpaste is injected into the bag in which the toothpaste sheet 1 is placed, and the toothpaste sheet 1 is impregnated with the toothpaste.
(how to use)

The figure which shows the usage example of Example 1 of the toothpaste sheet 1 which concerns on this invention is shown in FIG. As shown in this figure, an index finger is inserted into the insertion section 4, the palm-side holding section 5 is pressed with the thumb or middle finger, and the dirt on the teeth and the entire oral cavity is wiped off. When the surface of the toothpaste sheet 1 in use becomes dirty, the palm side and the back side of the hand are switched, and the teeth and the entire oral cavity are similarly wiped off. If the oral massage is performed together with the cleaning of the oral cavity, the blood circulation is improved, and alveolar pyorrhea and periodontal disease can be prevented. It can also contribute to prevention of dementia and improvement of diabetes.
(Evaluation test of water retention rate)

When the material presented in the present embodiment as the outer sheet and the inner sheet and the basis weight of the material indicates the measured value within the range required by the present embodiment, the measured value of the water retention rate is the present embodiment. In order to check whether it is within the range required by the above, a water retention rate evaluation test was conducted. As the outer sheet and the inner sheet, the water retention was measured by the following measurement method using the nonwoven fabric whose component and basis weight are shown in the table of FIG. Four types of samples of the outer surface sheet, Sample 1 to Sample 4, were prepared. In addition, four types of inner surface sheets, Sample 5 to Sample 8, were prepared.
(Measuring method)

The water retention rate was measured according to JIS L1913. Three test pieces of 100 mm x 100 mm are collected from the above-mentioned nonwoven fabric, put water in a container of an appropriate size, soak the test piece for 15 minutes or more, remove the test piece from the water with tweezers, and water for 1 minute or more. After dripping or dropping, the mass was measured to 1 mg. Thereafter, the water retention rate was calculated by the following formula, and the average value thereof was further calculated, and rounded to one decimal place according to JIS Z8401 rule B (rounding off method).
m = (m ₂ −m ₁ ) / m ₁ × 100
m: Water retention rate (wt%)
m ₁ : Mass of test specimen in standard state (mg)
m ₂ : Mass (mg) after wetting the test piece and draining or dropping water
(Evaluation of water retention rate)

Table 1 shows the result of the evaluation test of the water retention rate of the outer sheet and the inner sheet described above.

As described above, when the water retention rate of the outer sheet is required to be 600 wt% or more and 1500 wt% or less, as shown in Table 1, the value is within the required numerical range. Moreover, when the water retention rate of the inner surface sheet is required to be 0 wt% or more and 400 wt% or less, as shown in Table 1, the value is within the required numerical range.
(Evaluation test on the feeling of use of toothpaste sheet)

  Subsequently, in order to examine the feeling of use of the toothpaste sheet 1 according to the present invention, a commercially available oral care wet tissue (referred to as sample 9), a toothpaste sheet that does not have the fused portion 3 that functions as a stopper when pulling out a finger. (Referred to as sample 10), three kinds of samples of a toothpaste sheet (referred to as sample 11) formed in the embodiment 9 having a fused portion 3 that functions as a stopper when pulling out a finger, These samples are used by users who impose confidentiality and are used in three stages: (1) ease of cleaning, (2) difficulty of finger removal, and (3) comprehensive evaluation. I got the evaluation and obtained statistical data for 30 people.

As for the ease of cleaning in (1), 5 is the easiest to clean, 1 is the hardest to clean, and (2) is the hardest to remove the finger, 5 is the hardest to remove. The case where it is easy is set to 1. For the comprehensive evaluation of (3), in addition to (1) and (2), the case where the overall fit is good, including the feeling of finger fit and the feeling in the oral cavity, etc., 5 Is set to 1.
