Description

Technical Field

[0001] The utility model relates to a pull-out cylinder, in particular to a pull-out cylinder for non-woven fabrics with disinfectant and cleaning liquid. Background Art

[0002] Currently, disposable disinfected non-woven fabrics, disposable cleaning non-woven fabrics, etc. are widely used. To keep the non-woven fabrics clean, generally, the extraction type is adopted, which is convenient to use and will not contaminate other unused non-woven fabrics. For example, the commonly used plastic bag packaging in the market has a plastic lid combination fixed on the upper surface of the plastic. The plastic lid combination includes a lid piece and a fixing piece. The fixing piece is fixed to the plastic bag, and there is a through hole in the middle of the fixing piece. The upper surface of the plastic bag is open, and the opening is located at the through hole of the fixing piece. The lid piece cooperates with the fixing piece to keep the non-woven fabric in the plastic bag sealed, so that the humidity of the non-woven fabric in the plastic bag is not affected and the loss of moisture is prevented. At the same time, for the best use effect, such non-woven fabrics have a certain thickness and humidity, and functional liquids such as disinfectants or cleaning agents are stored on the non-woven fabrics. The company has previously applied for a pull-out cylinder for break-point non-woven fabrics, with the patent name of Pull-out Cylinder for Break-point Non-woven Fabrics and the application number of 202122446106.2. This pull-out cylinder is for thin non-woven fabrics. However, if this pull-out cylinder is used for thick non-woven fabrics, during the extraction process, the non-woven fabric will be frayed and the functional liquid stored on the non-woven fabric will also be squeezed out, affecting the humidity of the non-woven fabric and thus the use effect. Summary of the Utility Model

[0003] Based on the above description, the utility model provides a pull-out cylinder for liquid-storing and thick non-woven fabrics. The cover body is divided into an outlet hole, a passage and a tearing area, and can draw out the non-woven fabric. The utility model is applicable to break-point non-woven fabrics and extraction non-woven fabrics.

[0004] The technical solution adopted is: a pull-out cylinder for non-woven fabrics, including a cylinder body and a cover body. The cylinder body and the cover body cooperate to form a closed space. The cover body includes a lid and a lid piece. One side of the lid piece is connected to one side of the lid, and the lid piece can cover the lid. The lid cooperates with the cylinder body.

[0005] The lid piece is circular, and a connecting piece is provided on one side. A snap ring is fixed on the lid piece. The snap ring is circular.

[0006] On one side of the upper edge of the lid, a square groove is opened, and on the other side of the corresponding upper edge, a finger-shaped groove is opened. The connecting piece is installed on the square groove. There are an annular concave shape and a circular concave shape on the lid. The annular concave shape is located outside the circular concave shape, and the two are concentric. The diameter of the lid piece is the same as the diameter of the annular concave shape, that is, the lid piece covers the annular concave shape and the two fit together.

[0007] The circular concave shape is located at the center of the lid. A fixing ring is provided on the circular concave shape. There is a gap between the fixing ring and the circular concave shape, and the buckle ring can be placed in the gap.

[0008] The fixing ring is circular. The buckle ring and the fixing ring cooperate to cover the cover sheet on the annular concave shape to seal the cover body. The diameter of the upper edge of the fixing ring is larger than that of the lower edge. There is a pulling hole in the middle of the fixing ring.

[0009] An outlet hole is opened on the pulling hole, and a first elastic piece, a second elastic piece and a third elastic piece are also fixed on the pulling hole. There is a gap between the first elastic piece and the second elastic piece to form a passageway. There are gaps between the third elastic piece and the second elastic piece and the first elastic piece respectively, which is a tearing area. The outlet hole, the passageway and the tearing area are connected.

[0010] The tearing area and the passageway form a "triangle" outlet. The width of the passageway gradually becomes larger in the direction of the tearing area. The width of the tearing area gradually becomes larger in the direction of the lid edge.

[0011] Furthermore, the outlet hole is fan-shaped.

[0012] Furthermore, the first elastic piece and the second elastic piece have the same shape and are fixed on the pulling hole in a mirror image. The first elastic piece and the second elastic piece are arc-shaped.

[0013] Furthermore, the third elastic piece is semi-circular.

[0014] Furthermore, the endpoints of the tearing area are oval.

[0015] The pull-out cylinder for non-woven fabric of the present utility model can be applicable to various thicknesses, high moisture content of pull-out non-woven fabric or break-point non-woven fabric. If it is pull-out non-woven fabric, the non-woven fabric can be directly pulled out from the outlet hole. If it is break-point non-woven fabric, the non-woven fabric passes through the outlet hole and then along the passageway to reach the tearing area. The widths of both sides of the tearing area gradually become wider, which can prevent the functional liquid in the non-woven fabric from being squeezed. At this time, the tearing area will catch the non-woven fabric, and then pulling it obliquely upward can take out the break-point non-woven fabric. If the non-woven fabric is relatively thick and sometimes cannot be pulled off, it can be torn off by external force through the triangular outlet.

[0016] The diameter of the fixing ring gradually becomes smaller from top to bottom. The buckle ring overcomes the uppermost edge of the fixing ring and fixes the buckle ring on the fixing ring. At this time, the buckle ring is located between the fixing ring and the inner wall of the circular concave shape. The cover sheet is fixed on the lid. There are finger-shaped grooves on the lid. The finger passes through the finger-shaped grooves to overcome the upper edge of the fixing ring to open it.

[0017] The present utility model is applicable to liquid storage non-woven fabric with thick thickness and strong toughness, and can be used for both pull-out non-woven fabric and break-point non-woven fabric.

[0018] The present utility model can be reused by replacing the non-woven fabric inside. BRIEF DESCRIPTION OF THE DRAWINGS
