Technical Field

The present invention relates to the field of articles of daily use, and in particular to a tampon applicator.

Background

During the female physiological period, women can select different sanitary products according to different scenes and requirements. At present, most of the sanitary products available on the market are sanitary napkins, tampons, sanitary pads and menstrual cups. A tampon is an in-laid feminine hygiene product. Mainly divided into a hand-push type and a conduit type. The hand-push type is to insert the cotton strip into the body by directly contacting the finger with the cotton strip. The second type is a sanitary catheter using an applicator, by means of which the catheter is inserted. Known tampon applicators generally comprise an outer tube, a middle tube and an inner tube arranged in telescopic relationship to each other, the tampon being arranged in the outer tube, the middle tube being arranged behind the tampon in the outer tube and extending in a rearward direction outside the outer tube, the inner tube being arranged in the middle tube, the outer tube, the middle tube and the inner tube forming a telescopic tube, in use, the applicator is maximized in length by pulling out the inner tube, inserting the outer tube into the body and pushing the rearward extension of the inner tube in a forward direction towards the tampon, and the front part of the middle tube contacting the tampon and pushing it out of the outer tube and into the body of the user. Such applicators are relatively bulky.

Disclosure of Invention

Accordingly, in response to the above problems, the present invention proposes a compact tampon applicator.

In order to achieve the purpose, the invention adopts the following technical scheme: a tampon applicator comprises an outer tube, wherein the outer tube is a hollow cylindrical structure, the outer tube is defined to have an axial direction along a length direction and a radial direction perpendicular to the axial direction, one axial end of the outer tube is defined as an insertion end, the other axial end of the outer tube is a gripping area, a radially protruding buckling bulge is arranged on the inner wall of the outer tube at the gripping area, a radially protruding limiting strip is arranged on the upper side of the buckling bulge,

still including locating left arc section of jurisdiction and the right arc section of jurisdiction in the outer tube, left side arc section of jurisdiction and right arc section of jurisdiction have locate the inside body of outer tube and extend to the pull portion in the regional outside of outer tube gripping along the axial direction, be equipped with the hole of stepping down of dodging spacing on the body of left side arc section of jurisdiction and/or right arc section of jurisdiction, the body accessible pull portion of left side arc section of jurisdiction and right arc section of jurisdiction pulls out the back and coordinates the inner tube that forms to have hollow structure under the effect of lock protrusion, the inner tube is equipped with spacing arch in one side surface that the body of left arc section of jurisdiction and right arc section of jurisdiction is close to the end of inserting, spacing bellied minimum external diameter is greater than the bellied minimum internal.

Further improve, the buckle is protruding to include transition portion and the buckling parts that sets up along the axial, the internal diameter of transition portion reduces gradually to buckling parts direction, the internal diameter of buckling parts equals the external diameter of inner tube.

In a further improvement, the height of the buckling part is 2-8 mm.

Further improve, be equipped with the buffering portion that suits with the bellied transition portion of lock between the body of left side arc section of jurisdiction and right arc section of jurisdiction and the pull portion.

The improved structure is characterized in that the outer surfaces of the two sides of the left arc-shaped duct piece connected with the right arc-shaped duct piece are respectively provided with a convex strip along the axial direction, and the inner surfaces of the two sides of the right arc-shaped duct piece connected with the left arc-shaped duct piece are respectively provided with a concave strip matched and buckled with the convex strips along the axial direction.

Further improve, the both sides edge that the left arc section of jurisdiction is connected to right arc section of jurisdiction extends outwards and forms the perk portion.

The improved inner tube structure is characterized in that the number of the limiting strips is two, the two limiting strips are symmetrically arranged, and the minimum distance between the two limiting strips is larger than the inner diameter of the inner tube.

Further improve, be equipped with the antiskid portion of being convenient for the gripping on the pull portion of left side arc section of jurisdiction and right arc section of jurisdiction.

Further improvement, the width of the axial two ends of the abdicating hole is larger than the width of the middle part of the abdicating hole.

By adopting the technical scheme, the invention has the beneficial effects that:

1. the structure of the invention only comprises the outer pipe and the inner pipe, and when the device is not used, the inner pipe is almost completely accommodated in the outer pipe in the form of the left arc-shaped pipe piece and the right arc-shaped pipe piece, so that the device has compact and small structure and is more convenient to carry;

2. when the invention is used, because the inner pipe formed by buckling the left arc-shaped pipe piece and the right arc-shaped pipe piece is only contacted with the buckling bulge of the outer pipe, the contact area is small, and the friction force in the releasing process is obviously reduced and controlled;

3. the left arc-shaped duct piece and the right arc-shaped duct piece are provided with the abdicating holes which are matched with the limiting strips to play a role in guiding, meanwhile, in the application process, an air exhaust channel can be formed between the outer tube and the inner tube, and the abdicating holes enable the exhaust channel to be communicated with the outside, so that in the process of putting the tampon in, along with the insertion of the outer tube, air in the vagina is exhausted through the channel, the discomfort of a user is reduced, and the application of the tampon is smoother;

4. the height of the buckling part is 2-8mm, so that the inner pipe and the buckling bulges can be in surface contact, and the inner pipe is prevented from shaking to cause difficulty in application;

5. the buffer parts are arranged on the left arc-shaped duct piece and the right arc-shaped duct piece, so that the resistance of the left arc-shaped duct piece and the right arc-shaped duct piece when the left arc-shaped duct piece and the right arc-shaped duct piece just start to be pulled down can be reduced, and the operation is convenient;

6. the width at the two axial ends of the abdicating hole is larger than the width in the middle of the abdicating hole, so that the positioning strip is clamped into the abdicating hole when being assembled and applied, and the operation is more convenient.
