Description

Cup manufacturing method

The present invention relates to a method of manufacture, and more particularly to a method of making a cup of foam material into a bra.

Generally, the bras are designed differently according to the functional requirements, and have various shapes and structures. Among them, the design of the cups also differs from the materials used, and there are differences between the foam cups and the silk cups. Generally speaking, The silk cotton cup is made of a cloth with low deformation. The characteristics of the cup are better. However, because the softness, elasticity and ductility of the cloth are not as good as foam, the silk cup is not worn. Comfortable.

The foam cup is made of a foam material, so that it can produce better elasticity, ductility and flexibility, and is more comfortable to wear, but the foam structure has a relatively poor structural strength. In order to improve the structural strength of the foam cup, although the structural strength of the fabric covering the cup can be reinforced, the comfort of the foam cup can be reduced. Therefore, although the currently known cups can hold the breasts, it is difficult to achieve both structural strength and wearing comfort.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of manufacturing a cup which is simple and quick in process and which has a cup having a better structural strength and wearing comfort.

The manufacturing method of the present invention utilizes a mold to make a foam material into a cup body, and includes the following steps: a cutting step: cutting a cup substrate having a thickness variation on the foam material; Hot press forming step: The cup substrate is pressed into a cup body having different density regions by the mold.

The beneficial effect of the invention is that the above process is not only simple and fast, but also can form a high-density region with better structural strength and a low-density region with better softness on the cup body according to different requirements of various parts of the cup. The finished cup has both better structural strength and wearing comfort.

The foregoing and other objects, features, and advantages of the invention are set forth in the <RTIgt;

Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 1, 2, and 3, a first preferred embodiment of the manufacturing method of the present invention is to manufacture a cup 2 by the cooperation of a mold 3, the cup 2 comprising a foam material 1 having substantially the same density. The cup body 20 and a patch 23 attached to the outer surface of the cup body 20.

In the preferred embodiment, the cup body 20 of the cup 2 is arcuate in shape of the same thickness and includes a low density region 21 adjacent the middle and a high density region 22 surrounding the low density region 21. Also in the present invention, the low density region 21 and the high density region 22 are relative values, that is, the density of the low density region 21 is lower than the high density region 22.

The mold 3 includes two mold bases 31 which can be butted and separated, and a cavity 32 which is butted by the mold bases 31. The shape, size and curvature of the mold cavity 32 are matched with the formed cup 2, In the preferred embodiment, the depth H1 of the cavity 32 is uniform.

The manufacturing method of this embodiment includes a laminating step, a cutting step, and a hot press forming step.

The bonding step is to adhere the patch 23 to the foam material 1 , and the cutting step is to cut a cup substrate 10 having a shape substantially matching with the cup 2 on the foam material 1 , the cup The substrate 10 has substantially the same density and has a low-thickness region 101 at the intermediate portion and a high-thickness region 102 surrounding the low-thickness region 101. The applicator 23 is attached to the flat outer surface of the cup substrate 10, and the bonding step may also be after the cutting step in the manufacturing process, that is, the applicator may be attached after the cutting. twenty three.

In the hot press forming step, the cup base material 10 is hot pressed by the mold 3. When the cup substrate 10 is subjected to hot pressing of the mold 3, the cup base material 10 having a thickness change is to be hot-pressed to form a cup body 20 having a uniform thickness, and the depth H1 of the mold 3 is smaller than that of the cup substrate 10. The thickness H2 of the high-thickness region 102, therefore, after the hot pressing is completed, the high-thickness region 102 is hot-pressed and relatively solid, so that the high-density region 22 of the cup body 20 is formed, and the low-thickness region 101 is Since the thickness variation during the hot pressing is smaller than the high thickness region 102, the low density region 21 of the cup body 20 is formed.

That is, after the cup 2 is manufactured, the low-density region 21 of the cup body 20 is relatively soft and elastic, and provides better wearing comfort while surrounding the high density around the low-density region 21. The area 22 is relatively compact, so that it has better structural strength and supporting force. Therefore, the manufacturing method of the embodiment is not only simple and rapid, but also the cup 2 produced has better structural strength and wearing comfort.

Referring to Figures 4, 5 and 6, a second preferred embodiment of the manufacturing method of the present invention is used to manufacture a cup 2' which also includes a resilient cup body 20 and a patch 23, the cup body 20 includes a low density region 21 adjacent the bottom edge and capable of holding the breast, and a high density region 22 having a relatively higher density than the low density region 21, which in the preferred embodiment has a proximity The surrounding portion 221 of the edge and a recess 222 located above the low-density region 21, by the fluffy and holding of the low-density region 21, the breast can be displaced as far as possible to the recess 222 to achieve height and concentration The effect of the breast.

The manufacturing method also includes a patching step, a cutting step, and a hot press forming step, in which a cup substrate 10 having a thickness variation is also cut on the foam material 1. The cup substrate 10 has a high-thickness region 102 and a low-thickness region 101 surrounding the high-thickness region 102. The hot press forming step also heats the cup substrate 10 by a mold 3 and forms the cup 2'.

In the preferred embodiment, the thickness H3 of the low-thickness region 101 is greater than the depth H4 of the relative position on the cavity 32 of the mold 3. Therefore, after the hot pressing, a high density is formed due to compression compaction, that is, The high density region 22 of the cup 2' is formed and has a preferred structural strength. The thickness of the high-thickness region 102 is large, but since the difference between the depth H5 of the relative position of the cavity 32 of the mold 3 and the thickness H6 of the high-thickness region 102 is small, when the cup 2' is formed, the corresponding cup is formed. The density increase of the low density region 21 of the high-thickness region 102 of the substrate 10 is limited (or does not increase the density at all), and therefore, better flexibility and elasticity can be produced.

That is, the manufacturing method of the present embodiment can easily and quickly produce a cup having a height and a concentration effect by changing the shape of the cavity 32 of the mold 3 and the thickness of the cut cup substrate 10. 2'.

As apparent from the above description, the present invention cuts the cup base material 10 having a thickness variation on the foam material 1 by using a cutting step, and at the same time, the hot press forming step is performed on the cup base material 10 by the hot press forming step. In the region of density, the above manufacturing method is not only innovative, but also the high-density region 22 and the low-density region 21 are formed on the cups 2, 2' by a simple and fast process, which may have different flexibility due to different densities. The elastic and structural strengths of the present invention also enable the finished cups 2, 2' to have better structural strength and wearing comfort.

In terms of design, the present invention is not limited to forming a single high-density region 22 and a single low-density region 21 on the cups 2, 2', and the change in density may also be progressive, that is, the present invention may be by the cup The thickness of the substrate 10 varies, or by the change in the depth of the cavity 32 of the mold 3, the density of the formed cups 2, 2' is gradually increased or decreased from a certain area to the set area.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
