Problems solved by technology

[0004] The above-mentioned breast pads of the prior art have the disadvantage that: the body includes a water-absorbing layer (that is, an absorber), and for the convenience of forming the breast pad into a tapered shape during use, the incision 6 must be provided, and the incision The emergence of 6 leads to the loss of the volume of the water-absorbing layer of the breast pad in the case of the same external size, which in turn leads to a reduction in water absorption, which in turn increases the frequency of breast pad replacement and the cost of use for users

Embodiment 1

[0050] The breast pad of this embodiment includes: a water-conducting layer 1 (generally non-woven fabric, spunlace non-woven fabric, pure cotton cloth and other water-conducting materials), a water-absorbing body 2 and a waterproof layer 3 (generally PE film or other non-water-permeable membrane material); the breast pad is folded inward along the center line, so that the water-conducting layer 1 forms adjacent stacks, and the laminated water-conducting layers 1 are connected along a line, so that the breast pad unfolds A substantially conical cavity is formed.

[0051] The water-conducting layer 1 of the laminate is connected along the line (such as Figure 5 with 6 ).

[0052] Such as Figure 9 , the water absorbent body 2 includes a laminated upper absorbent layer 2-2 and a water absorbent core 2-1, and the upper absorbent layer 2-2 and the water absorbent core 2-1 are wrapped by toilet paper 2-3; the upper absorbent layer 2-2 is fluff pulp, and the water-absorbing cor...

Embodiment 2

[0060] On the basis of Embodiment 1, there are the following modifications in this embodiment:

[0061] The laminated water-conducting layers 1 are connected along two lines, so that when the breast pad is unfolded, a substantially tapered cavity is formed.

[0062] The laminated water-conducting layer 1 is along the two lines (such as Figure 7 with 8 ) connected.

[0063] The production method of above-mentioned breast pad, comprises:

[0064] A. Fold the water-guiding layer 1 continuously distributed in a straight line in half along the centerline of the length direction, one side of the water-guiding layer 1 folded in half is the closed side 1-1, and the other side is the open side 1-2;

[0065] B. Forming along the closed side 1-1 of the water-conducting layer 1 by means of glue, heat-synthesizing, or ultrasonic welding: a plurality of fold lines distributed alternately for connecting the laminated water-conducting layers 1 to each other or line-segment-shaped connect...

Embodiment 3

[0070] A breast pad 5, comprising: a water-conducting layer, a water-absorbing body, and a waterproof layer stacked in sequence; the breast pad is folded inward along the center line and shaped so that when the breast pad is unfolded, it forms a substantially conical or hemispherical cavity.

[0071] The shaping refers to connecting the laminated layers of 4 at any end corner of the water-absorbing body in the double-folded breast pad, and the connection method is continuous or intermittent, specifically connected by glue or suture, such as Figure 4 Or 5. Or connect the laminated water-absorbing body 2 at any end corner by nailing (using plastic nails).

[0072] The production method of described breast pad comprises:

[0073] a. Place the water-absorbing body 2 on a water-guiding layer 1, and fold it in half along the center line of the water-absorbing body 2, and make the water-guiding layer 1 inside;

[0074] b. Connect the laminated layers at one or both ends of the wat...

Abstract

The invention relates to a breast pad without a gap in the water-absorbing layer and a production method thereof. The breast pad comprises: a water-conducting layer, a water-absorbing body and a waterproof layer stacked in sequence; there is no gap in the water-absorbing body, and the breast pad moves inward along its center line Fold in half and shape so that the breast pad forms a substantially conical or hemispherical cavity when unfolded. During production, the breast pad is folded inward along the center line, so that the water-conducting layers form adjacent laminates, and the laminated water-conducting layers are connected along one or two lines, so that when the breast pad is unfolded, it forms a basic The tapered cavity eliminates the need to set cuts on the water-absorbing layer, so that the volume of the water-absorbing layer of the breast pad is not lost, thereby increasing the water absorption of the water-absorbing layer, which can reduce the frequency of breast pad replacement and use costs for users.

Description

technical field [0001] The invention relates to the technical field of breast pads, in particular to a breast pad with no gap in the water-absorbing layer and a production method thereof. Background technique [0002] Such as Figure 1-2 , the Chinese patent document CN202095548U discloses a disposable breast milk overflow pad (also called a breast pad), which includes a body 5 (absorbent layer). A cutout 6 is molded, and the edges of the cutout 6 are bonded to form a depression on one side of the body 5 to form a three-dimensional 3D shape, which fits the chest better and is more comfortable to use. [0003] Another breast pad in the prior art is, as Figure 4 A pair of symmetrically distributed fan-shaped cutouts 6 are arranged on the water-absorbing layer, and after the breast pad is folded in half along the center line of the cutout, the water-conducting layer and the waterproof layer at the edge of the cutout are heat-synthesized to form a heat-sealing part 6-1, The b...
