Description

The present invention relates to a non-sewn slipper which is constructed by combining footwear, particularly felt, and can be used on one side or both sides, and a method for manufacturing the same.

Slippers are used as simple footwear in hospitals and homes. Recently, it is often used in transportation, especially in airplanes and hotels. The use of slippers on airplanes and hotels is more disposable than using the same slippers repeatedly.
In general, slippers are composed of toes and footrests, and the material is made of plastic, cloth (unemployed cloth), paper, etc., but especially disposable ones are made of cloth or paper. There are many (refer patent document 1).

Disposable slippers are intended for temporary use, and the toe and footrests are simpler and easier to construct than slippers intended for long-term use. . However, for that reason, comfort and satisfaction during use are not high.
In general, slippers include a step of sewing, which makes it difficult to reduce costs.
On the other hand, as a slipper material used in daily life, a felt is often used from the viewpoint of the feel to the human body and the elasticity of the material. For example, a wool fiber for use at the bottom of the slipper. A felt manufactured by shrinking is also used (see Patent Document 2).
JP 2002-186501 A JP-A-9-95845

By the way, since conventional disposable slippers are made of paper or cloth, they have a strong feeling of thinness when used and do not have good appearance and comfort.
In addition, it is conceivable to use a felt because of its characteristics, but it generally includes a sewing step, and is not applied to a simple disposable slipper from the viewpoint of cost and manufacturing.

The present invention provides a disposable slipper that solves the above-mentioned conventional problems. In particular, the present invention provides a slipper that uses felt that has been partially used in ordinary slippers for most parts. is there.

The non-sewn slipper of the present invention is a portion that becomes a bottom portion formed by sandwiching a core material in one linear portion of the substantially cross shape between fiber material layers having different colors from each other in a substantially cross shape, It said generally made from both ends of the cross-shaped other linear portion, wherein a bottom portion and a portion to be the upper portion integrally formed, and the bottom portion to become part of a felt feet to be overlaid on both sides rest portion, the instep It is provided in the both ends of the part used as a part, and the connection member which connects them is provided, It is characterized by the above-mentioned.

In the non-sewn slipper of the present invention, the core material is a nylon cloth.

Further, the non-sewn slipper of the present invention is characterized in that the fiber material layer is a wool having a compaction property.
Further, the non-sewn slipper of the present invention is characterized in that an insole is further bonded onto the footrest portion.

Furthermore, the method for manufacturing a non-sewn slipper according to the present invention includes both sides of a core material made of a nylon cloth sandwiched between two fiber material layers that are compact and have a substantially cross-shaped planar shape. , those obtained by superimposing a felt footrest, and immobilized between the members by fulling, a portion that becomes a bottom portion formed on one of the straight portions of the substantially cross shape, the substantially cross-shaped and a portion to be the upper part consisting of two end portions of the other linear portion formed integrally, then above a felt footrests, condensation and a footrest and the felt and the tape-like felt was cut in the same shape paste with an adhesive to prepare insole by charging, characterized by further providing a connecting portion at both ends of the portion to be the front Kikabuto unit.

The present invention has a good feel to the human body as a simple slipper, and also looks and is easy to use. Further, since the nylon cloth is used as the core material, the strength of the footrest portion is increased, the durability as a slipper is increased, and the temporary use time is increased. Further, when the insole is affixed to the footrest portion, the insole portion absorbs an impact during use, and the uneven portion gives a comfortable stimulus to the sole.
The non-sewing slipper of the present invention can be manufactured without a sewing process, and is therefore effective in reducing costs.

Embodiments of the present invention will be described with reference to the drawings.
1 to 3, the basic members constituting the slipper of the present invention will be described. After carding, the wraps 1a and 1b, which are wool cottons that have been opened, are inserted as core material 2 between the wraps. It consists of nylon cloth and the footrest part 3 piled up on the said wrap.

A method for manufacturing a non-sewn slipper having the above-described configuration will be described below.
First, from a separately manufactured felt fabric (press felt), a foot mold is punched out to make a footrest portion 3 shown in FIG.
Then, the wraps 1a and 1b shown in FIG. 2 are obtained by dyeing carded wool cotton in advance so as to have different colors from each other to obtain a desired thickness (for example, several cm, 3 cm to 5 cm), It is cut by applying (substantially cross shape).

Next, a nylon cloth to be the core material 2 shown in FIG. 3 is prepared. The thickness of the core material 2 and the footrest portion 3 is several mm, but the thickness can be selected as desired.
Next, the above members are overlaid as shown in FIG. First, as shown in FIG. 5, a wrap 1a made of substantially cross-shaped wool cotton is spread on a harder as a compacting machine, and an appropriate number of nylon cloths serving as the core material 2 are arranged on one of the substantially cross-shaped straight portions. Next, a substantially cross-shaped wrap 1b having a color different from that of the wrap 1a is stacked in the same shape as the wrap 1a with the same thickness as the wrap 1a. Then, when the superposed ones are contracted by a harder, the whole is compressed and integrated as shown in FIGS. 5 and 6. As a result of pressure being applied to the wraps 1a and 1b in the process of contraction, the wraps 1a and 1b and the felt fabric are thinned (about 2 to 3 mm) as felt members 11a and 11b, respectively, and the core material 2 is sandwiched between them. The footrest portion 3 is entangled with each other so that the portion that becomes the bottom portion 5 of the slipper and the footrest portion 3 are integrated, and further, both end portions 4a and 4b (substantially) that become the upper portion with respect to the portion that becomes the bottom portion 5. An integrated one in which both ends of the other cross-shaped straight portion are continuous is obtained.

In addition, in order to strengthen the coupling | bonding of the footrest part 3 and the felt members 11a and 11b, you may adhere | attach the front-end | tip part and rear-end part of the footrest part 3 to the felt members 11a and 11b with an adhesive agent. .
In addition, although there is a portion that protrudes from the footrest portion 3 in the bottom portion 5, there is no step of intentionally cutting the protruding portion 7. The thickness of the footrest is about 5 mm, and the other portions are about 2 to 3 mm (the thickness of the cotton of the lower felt 1a and the upper felt 1b before shrinking is about 3 cm, the core material 2 and the footrest 3) Each thickness of about 3 mm).

Next, the connection part for connecting the both ends 4a and 4b used as an upper part is produced. As for a connection part, both ends 4a and 4b may be connected with a hook_and_loop | surface fastener, you may cut | inscribe both ends 4a and 4b, and you may connect with a string. Further, the projection provided on the other hand of the end portions may be connected crowded placed in notches provided on one another. All of these connecting means are conventionally known.

The slippers manufactured as described above can be worn by selecting one of the surfaces as shown in FIG. 7, placing the foot on the footrest 3 and connecting the both ends 4a and 4b. If another surface is selected, it becomes a double-sided slipper. In this case, since the colors of the felt member 11a and the felt member 11b are different from each other, depending on which surface is used, the color at the time of wearing the slippers can be enjoyed different from the case of only one side.

Next, another embodiment will be described with reference to FIG.
In the step (A), a plurality of felts 21 of various colors are prepared, and the corrugated segment 22 is cut therefrom (step B). Next, an appropriate color wrap and a section 22 of various color waveforms obtained in the process B are overlapped, and are applied to a harder to be contracted. Then, on the felt 23, the sections 22 ', 22 ", 22""of various color waveforms appear as irregularities of about 1 mm (step C). If a foot mold is applied to this and punched out, an insole having a section 22 or the like in the foot mold portion 24 is formed (step D).
Next, in the one shown in the cross-sectional view taken along the line AA in FIG. 5, the insole is bonded to the front and back footrest portions 3 with an adhesive. Compared with the first embodiment, this slipper can reduce the impact during use, and can provide irritation to the sole by the unevenness.

Slippers manufactured as described above can be used as appropriate in transportation or hotels,
Because the entire slippers are made of felt, the feel to the foot is very good and can be used easily in terms of disposal after use.
Moreover, if the degree of the protrusion which floats on the surface is increased by the shape and number of the core members or the combination thereof, the acupressure effect on the sole can be given due to the structure of the slipper.

Furthermore, in the slipper manufacturing process, the upper and lower cottons are overlapped and the surface after the shrinking is sufficient if it is larger than the size of the footrest part, and the part that protrudes from the footrest part is provided with a process of cutting off. Absent. The overall shape is indefinite, but this has nothing to do with the function of the slipper, and the manufacturing cost is reduced by reducing the number of processes.
Since there is no sewing process in the entire work process, it can be manufactured in a series of processes by a machine.
