Abstract
Description
Technical Field
[0001] The utility model relates to the field of female sanitary products, in particular to a rolled sanitary napkin. Background Art
[0002] Sanitary napkins are commonly used sanitary products for women during menstruation. The body of traditional sanitary napkins is roughly rectangular in shape. In order to facilitate carrying and meet hygiene requirements, such as Figure 6 As shown in FIG. 1 , the outermost layer of the sanitary napkin body is attached with a film layer 30. After the sanitary napkin body and the film layer 30 are combined together, the front and rear ends are folded toward each other once and the two ends folded toward each other are attached together using an easy-to-tear adhesive tape 31, thereby shortening the length of the sanitary napkin body (in the x direction). Figure 6 The left and right sides of the sanitary napkin are respectively compression molded to form a edging 33. The edging 33 and the adhesive label 31 are used together to protect the sanitary napkin body from the invasion of pollutants. However, due to the existence of the edging 33 and the space 32 (the space 32 is the space left between the edging 33 and the sanitary napkin body to avoid damaging the sanitary napkin body when the edging 33 is formed), the width L1 of the wrapped sanitary napkin (y direction, that is, the width of the film layer) is greater than the width L1' of the sanitary napkin body (20%-40% greater). The length L2 of the wrapped sanitary napkin is approximately 1 / 3 of the length of the sanitary napkin body. Several single sanitary napkins packaged in this way are stacked and packaged together to form a sales unit (i.e., a package).
[0003] Even if folded like Figure 6 As shown in the figure, the area of the conventional sanitary napkin is still relatively large, usually larger than the palm size of an average adult female, so it is easy to be exposed from the palm of an average adult female and be observed. Even if it is placed in a pocket of clothing, it is easy to be exposed at the edges and corners. Thus, it causes embarrassment and inconvenience to the user. In addition, women usually carry one or several sanitary napkins instead of a whole pack of sanitary napkins, and these sanitary napkins are easily contaminated after being taken out of the sales unit, which also leads to waste. Utility Model Content
[0004] The utility model aims to provide a roll-shaped sanitary napkin in view of the defects and shortcomings of the prior art, which is clean, hygienic and easy to carry, thereby avoiding waste.
[0005] The utility model discloses a rolled sanitary napkin, comprising a surface layer, a napkin body, a breathable bottom film layer and a film layer stacked in sequence.
[0006] The towel body is composed of a first dust-free paper wrapping layer, an absorbent layer and a second dust-free paper wrapping layer, and the absorbent layer is arranged between the first dust-free paper wrapping layer and the second dust-free paper wrapping layer.
[0007] The envelope layer is adhered to the breathable bottom film layer and can be easily torn off from the breathable bottom film layer. The width of the envelope layer is 2 to 3 times the width of the towel body. Both sides of the envelope layer are folded toward each other to completely wrap the surface layer to form a straight strip towel body.
[0008] Among them, one end of the straight strip of towel body is a first rolling end, the first rolling end is the starting point of rolling up the straight strip of towel body around a first direction, the straight strip of towel body also has a second rolling end, rolling up the second rolling end is the end point of rolling up the straight strip of towel body around the first direction, the second rolling end is also the starting point of rolling up the straight strip of towel body around a second direction opposite to the first direction, the other end of the straight strip of towel body opposite to the one end is the end point of rolling up the straight strip of towel body around the second direction, and the straight strip of towel body forms a rolled towel body after the first rolling and the second rolling.
[0009] Preferably, the rolled sanitary napkin further comprises an easy-tear adhesive tape, and the easy-tear adhesive tape is arranged on the envelope layer.
[0010] Preferably, the rolled sanitary napkin further comprises a sealing sleeve, and the rolled napkin body is placed in the sealing sleeve.
[0011] Preferably, the sealing sleeve is in a cylindrical, tetrahedral or hexahedral shape.
[0012] Preferably, the width of the envelope layer is 2.1 to 2.2 times the width of the towel body.
[0013] Preferably, both sides of the envelope layer can be sealed after being folded to cover the surface layer.
[0014] Preferably, the sealing is a heat and pressure seal.
[0015] Preferably, first wings are arranged on both sides of the breathable bottom film layer, and second wings are arranged at corresponding positions on both sides of the surface layer. After the first wings and the second wings are fixed together, they can be folded toward each other and placed on the surface layer.
[0016] After adopting the above structure, the roll-shaped sanitary napkin of the utility model has the following beneficial effects: the coating layer of the roll-shaped sanitary napkin described in the utility model directly wraps the sanitary napkin body completely, but the size of the coating layer is designed so that the sanitary napkin wrapped with the coating layer is not much different from the size of the sanitary napkin body, so that the overall width of the sanitary napkin is reduced relative to the traditional sanitary napkin. In addition, after the sanitary napkin is rolled into a reel-like cylinder by adopting this folding method after the two rolling operations, the overall length of the sanitary napkin is also reduced relative to the traditional sanitary napkin. Therefore, the roll-shaped sanitary napkin described in the utility model can be wrapped by the hands of most women ("one-handed"), which is convenient to carry and does not affect the cleanliness and hygiene of the sanitary napkin body, and can also avoid the embarrassment caused by taking it in public places.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0029] like Figure 1 As shown, a rolled sanitary napkin of the utility model is a flat sanitary napkin body ( Figure 2 The sanitary napkin body after the layers are combined as shown in the figure is rolled up. An easy-to-tear adhesive sticker 8 is arranged at the end C of the rolled sanitary napkin body to fix the shape of the roll and help maintain the hygiene of the sanitary napkin body.
[0030] like Figure 2 As shown, the sanitary napkin body 100 includes a surface layer 1, a body 7 and a breathable bottom film layer 5 stacked in sequence. The body 7 is composed of a first dust-free paper wrapping layer 2, an absorbent layer 3 and a second dust-free paper wrapping layer 4. The absorbent layer 3 is arranged between the first dust-free paper wrapping layer 2 and the second dust-free paper wrapping layer 4. The shape of the surface layer 1 and the breathable bottom film layer 5 (except for the wings) is roughly the same as that of the body 7, and the size of the two is equal to or slightly larger than the size of the body 7, so as to cover the body 7.
[0031] The surface layer 1 is provided with wings 11 on both sides, and the breathable bottom film layer 5 is also provided with wings 51 at corresponding positions on both sides. The wings 11 and the wings 51 are fixed together and folded toward each other and placed on the surface layer 1.
[0032] The sanitary napkin body 100 further includes a film layer 6, which is adhered to the breathable bottom film layer 5 and can be easily torn off from the breathable bottom film layer 5. The length of the film layer 6 located on the bottom surface of the sanitary napkin body 100 is ( Figure 2 The x direction, and Figure 6The x direction is the same as that indicated by the x direction, which is the length direction of the sanitary napkin body) is slightly larger than the other layers, and the width of the envelope layer 6 ( Figure 2 The y direction of the envelope layer 6 is greater than that of the other layers (e.g., greater than the width of the towel body 7). For example, the width of the envelope layer 6 is 2 to 3 times the width of the other layers (e.g., the towel body 7), such as 2.1 times, 2.2 times, or 2.3 times the width of the towel body 7. Figure 2 The left and right sides of the sanitary napkin 100 can be folded toward each other to completely wrap the surface layer 1 of the sanitary napkin body 100, thereby forming a closed straight strip of napkin body. Figure 3 The two sides of the folded envelope layer 6 are heat-pressed together to form a seal (to form a closed straight strip towel body), so that after wrapping the surface layer 1, the two sides of the envelope layer 6 can be fixed together to ensure the cleanliness of the surface layer 1.
[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the straight strip of towel has an end A and an end C. The straight strip of towel is rolled up from the end A of the straight strip of towel until B (for example, rolled up in a counterclockwise direction), and then from B, the AB segment of the straight strip of towel is rolled up in the opposite direction from B (for example, rolled up in a clockwise direction) until the C end, thereby forming a rolled towel. In other words, A is the first rolling end of the straight strip of towel, which is the starting point of the first rolling operation, and the first rolling operation is the operation of rolling up the straight strip of towel around a first direction. B is the folding point, and is also the second rolling end of the straight strip of towel. B is the end point of the first rolling operation, and is also the starting point of the second rolling operation, and the second rolling operation is the operation of rolling up the straight strip of towel around a second direction opposite to the first direction. End C is the end point of the second rolling operation. The straight strip of towel forms a rolled towel (as shown in FIG. 1 ) after undergoing the first rolling operation and the second rolling operation in sequence. Figure 4 As shown in FIG. 1 ). Thus, the AB section of the straight strip towel body forms a structure similar to a "scroll". After the rolling operation is completed, use the easy-to-tear adhesive tape 8 (as shown in FIG. 1 ). Figure 1 ) Paste the C end with the rest of the rolled up part to form the final scroll-like cylinder (i.e., the roll-shaped towel body, such as Figure 1 Such a rolling method is beneficial to keep the sanitary napkin body originally flat after unfolding a rolled sanitary napkin.
[0034] like Figure 5 As shown, the width L3 of a rolled sanitary napkin of the utility model is substantially equal to the width of the sanitary napkin body, and the length L4 is substantially equal to 1 / 6 of the sanitary napkin body.
[0035] Specifically, a roll-shaped sanitary napkin of the utility model is cylindrical, and its end surface is roughly circular, with a diameter of about 2.5 cm and a width L3 (roughly the width L1' of the sanitary napkin body) of about 9 cm. Therefore, the area of a roll-shaped sanitary napkin is about 22.5 cm 2 , the volume is approximately: 3.14×1.25 2 cm×9cm=44.16cm 3 .
[0036] like Figure 6 As shown, due to the need to set the edge 33 to ensure the hygiene of the traditional sanitary napkin 200 and the existence of the space 32, the width L1 of a single traditional sanitary napkin after packaging is generally about 13cm. In order to ensure the thickness of a single traditional sanitary napkin, the two sides of the traditional sanitary napkin are generally folded once to form a sanitary napkin package with a total thickness of about 5mm. Therefore, the length L2 of a traditional sanitary napkin is generally about 10cm (about 1 / 3 of the total length of the sanitary napkin after unfolding). Therefore, the area of a traditional sanitary napkin is about 130cm 2 About 65cm 3 This is much larger than the palm area of an average adult woman, and it is difficult for a woman's hand to completely cover a traditional sanitary napkin.
[0037] It should be noted that the above dimensions are measured based on the dimensions of sanitary napkins commonly used in the prior art, and other dimensions may be available.
[0038] It can be seen that the rolled sanitary napkin of the utility model is superior to the traditional sanitary napkin in terms of length, width, area and volume. Generally, an adult female can completely wrap the rolled sanitary napkin with one hand, thus avoiding the embarrassment of being exposed when taking it and making it easy to carry.
[0039] Furthermore, if Figure 7 and Figure 8 As shown, a rolled sanitary napkin further comprises a sealing sleeve (also called a "sealing box" or "outer packaging") 9. Figure 1 The illustrated roll-shaped sanitary napkin can be placed in the sealing sleeve 9. After the roll-shaped sanitary napkin is placed in the sealing sleeve 9, the sealing sleeve 9 can be sealed, thereby further ensuring the hygiene of the roll-shaped sanitary napkin. In order to control the size, the sealing sleeve 9 is designed to roughly just accommodate a roll-shaped sanitary napkin, so that the size of a roll-shaped sanitary napkin with the sealing sleeve will not be disadvantageously increased.
[0040] The sealing sleeve 9 can be in the same shape as a cylindrical shape after a rolled sanitary napkin is rolled up, such as Figure 7 and Figure 8 Alternatively, the sealing sleeve 9 may be a quadrilateral or a hexagon (eg Fig. 9As shown). A roll-shaped sanitary napkin with such a sealing sleeve is similar in appearance to a lipstick or a lipstick package, and there is no embarrassment even if it is accidentally seen by a third person when taking it.
[0041] This design aims to solve the problem that traditional sanitary napkins are inconvenient to carry. The sanitary napkin is rolled into a scroll shape and the envelope layer is modified, which reduces the space occupied by a sanitary napkin while ensuring the hygiene of the sanitary napkin.
[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
