Description

[Detailed explanation of the idea] The present invention relates to a three-dimensional diaper cover.

Flat-knitted fabrics with a double-sided knitting structure have dense stitches that give them a soft feel, and they have high stretchability in the course direction but low restoring force, while low stretchability in the wale direction but low restoring power. It has the characteristic of being strong.

The present invention focuses on the characteristics of the flat knitted fabric produced by such double-sided knitting, and its purpose is to cut and form the flat knitted fabric so that the longitudinal direction of the edge wrapping piece is in the wale direction of the flat knitted fabric. By attaching this hem wrapping piece to the leg circumference of the three-dimensional diaper cover, it is possible to prevent the three-dimensional diaper cover from deforming. The purpose is to prevent damage to the skin caused by the winding pieces.

That is, in order to achieve this objective distantly, the three-dimensional diaper cover of the present invention includes a main body cover 1 in which the curvature of the joint curved edge 1a is smaller than the curvature of the joint curved edge 2a of the side covers 2, 2, and a joint curved edge. The side covers 2, 2 whose curvature is larger than the curvature of the joint curved edges 1a of the main body cover 1 are cut separately, and the double force bars 1.2 are joined along the joint curved edges 1a, 2a. In this three-dimensional diaper cover, in which the edge wrapping piece 3 is attached to the foot surrounding edge 2b of the armpit cover 2, the side cover is knitted into a double-sided knitted structure using stretchable synthetic yarn as a material. The knitted fabric 3a is cut in the wale direction to form a band-shaped edge wrapping piece 3 such that the wale direction of the flat knitted fabric 3a is the longitudinal direction, and the edge wrapping piece 3 is cut into the wale direction of the flat knitted fabric 3a. The armpit cover 2 is attached to the foot circumference edge 2b of the armpit cover 2 in a direction along the foot circumference direction.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a three-dimensional diaper cover A that is an embodiment of the present invention, and FIG. 2 is a developed view of the three-dimensional diaper cover A.

In the figure, 1 is a main body cover, and 2 and 2 are left and right side covers, and these double-sided bars 1 and 2 are cut separately.

Next, 1a and 1a are the joining curved edges of the main body cover 1, and 2
a is the joining curved edge of the side cover 2, and both joining curved edges 1a
, 2a are formed to have the same length, and the main body cover 1
The curvature of the joint curved edge 2a of the side cover 2 is larger than the curvature of the joint curved edge 1a.

The diaper cover A having a three-dimensional structure is formed by joining the main body cover 1 and the side cover 2 along the curved joining edges 1a and 2a by stitching or welding.

Further, reference numeral 2b denotes a foot surrounding edge of the side cover 2, and a band-shaped edge wrapping piece 3 is attached to this foot surrounding edge 2b.

Next, FIG. 3 is a perspective view of a rolled-up flat knitted fabric 3a, which is knitted into a double-sided knitted structure by a circular knitting machine using stretchable synthetic yarn as a material. This is unfolded and rolled up.

Note that the term "stretchable synthetic fiber processed yarn" here refers to filament yarn made of synthetic fibers such as nylon that has undergone special processing such as heat untwisting treatment to impart elasticity to the fibers. Refers to yarns that use composite yarns such as twisted heating, false twisting heating, and conjugate yarns.

Then, the flat knitted fabric 3a knitted as described above is used to cut and form the edge wrapping pieces 3. In this case, as shown by the imaginary line in FIG. 3, the wale direction of the flat knitted fabric 3a is The edge wrapping piece 3 is cut and formed in the longitudinal direction.

Then, the band-shaped edge wrapping piece 3 cut and formed as described above.
is attached to the foot circumference 2b of the side cover 2. In this case, the wale direction of the flat knitted fabric 3a is aligned with the foot circumference direction, and the hem wrap piece 3 is sewn or welded to the foot circumference 2b. It has an attached hem wrap structure.

Incidentally, upon this installation, the edge wrapping piece 3 is folded in half as shown in FIG. 4 so as to wrap around the foot surrounding edge 2b.

Therefore, when the foot circumference hem wrap structure configured as described above is used for the three-dimensional diaper cover A, the required length of the hem wrap piece is shorter than when used for a flat diaper cover.
This means that you can save on fabric.

In addition, in order to obtain a curvature around the legs of a flat diaper cover, it is necessary to attach a highly stretchable hem wrapper in a stretched state, and use the restoring force of this hem wrapper to curve the foot surround.
In the three-dimensional diaper cover A, since the underbody is curved from the beginning, when attaching the hem wrapping piece 3, the hem wrapping piece 3 can be attached in its normal restored state without stretching it.

This means that in a three-dimensional diaper cover, there is no need to provide stretchability to the hem wrapper, but if it were to have a large amount of stretchability, the stitches would become rough when stretched, causing skin damage or causing repeated wear and tear. The inconvenience of sagging occurs due to use, but as a structure to deal with this, the wale direction of the flat knitted fabric 3a knitted on both sides is aligned with the direction of the foot circumference to reduce the extensibility of the foot circumference. The edge-wrap structure of the present invention has a great effect in that it can prevent skin damage while fully taking advantage of the soft feel that is a characteristic of flat-knitted fabrics created by double-sided knitting.

In addition, the three-dimensional diaper cover has a joint curved edge 2 of the side cover 2.
It is formed three-dimensionally by curving the main body cover 1 along the direction a, and therefore, maintaining the shape of the side cover 2 means maintaining the shape of the entire three-dimensional diaper cover A, but in this case , foot surrounding edge 2b of side cover 2
In the proposed edge-wrapping structure in which the edge-wrapping piece 3 with low extensibility and strong restoring force is attached to the edge-wrapping piece 3, the edge-wrapping piece 3 prevents the side cover 2 from sagging or deforming, and this prevents the side cover from deforming due to repeated use such as washing. This prevents deformation and maintains its three-dimensional structure for a long period of time.

Since the leg wrap structure of the present invention is constructed and operates as described above, it has a hem wrap structure that is most compatible with the three-dimensional structure unique to three-dimensional diaper covers, and also prevents damage to the wearer's skin. It is also possible to prevent the three-dimensional diaper cover from deforming.
