Description

Technical Field

[0001] The present invention relates to the technical field of tipping paper, and in particular to a pair of tipping papers. Background Art

[0002] At present, many cigarette factories make cigarettes meet the needs of more smokers by changing the ventilation amount of the filter tip part. For example, there is a kind of filter tip with one or several circles of perforations in the middle. Smokers can cut off the filter tip at the perforations according to their own needs, so as to form filter tips of different lengths to meet personalized needs. However, the cut-off part formed in this way is relatively rough and not beautiful and practical enough. Summary of the Invention

[0003] The purpose of the present invention is to provide a pair of tipping papers, which have the characteristics of relatively flexible use.

[0004] The technical solution adopted by the present invention is: a pair of tipping papers, the pair of tipping papers includes a left piece and a right piece both prepared from tipping base paper. The left side of the right piece is pressed on the right side of the left piece, and adhesive strips extending in the left-right direction are evenly adhered to the upper surface of the left piece. The adhesive strip includes a base layer and an adhesive coated on the lower surface of the base layer. At the same time, the right part of the adhesive strip extends to the left side of the right piece.

[0005] No adhesive is provided on the lower surfaces of both ends of the base layer.

[0006] The base layer is prepared from a polypropylene film.

[0007] By weight percentage, the raw material components of the adhesive are: 80-90% of aqueous natural latex, and the rest is ethylene-vinyl acetate copolymer emulsion.

[0008] A set of perforations is provided below each adhesive strip on the left piece, and each set of perforations is in a "U" shape with the opening facing left.

[0009] The advantages of the present invention compared with the prior art are: relatively flexible use. The pair of tipping papers of the present invention adopts a two-section structure. When rolled into a filter tip, the acetate fiber inside can also be set into two sections according to needs. Smokers can adopt different filter tip lengths according to needs. Brief Description of the Drawings

[0010] The present invention will be further described below with reference to the drawings and embodiments:

[0011] Figure 1 is a top view of the pair of tipping papers of the embodiment of the present invention;

[0012] Figure 2 is Figure 1 the view in the direction of A-A of

[0013] In the figure:

[0015] 20, right piece;

[0016] 30, adhesive strip; 31, base layer; 32, adhesive. Specific implementation mode

[0017] In the embodiment, see Figure 1 and Figure 2 as shown: The butt-jointed paper includes a left piece 10 and a right piece 20 both prepared from tipping base paper. Obviously, both the left piece 10 and the right piece 20 are square. The left side of the right piece 20 is pressed on the right side of the left piece 10. That is, a part of the right piece 20 and the left piece 10 overlap. An adhesive strip 30 extending in the left-right direction is evenly adhered to the upper surface of the left piece 10. The adhesive strip 30 includes a base layer 31 and an adhesive 32 coated on the lower surface of the base layer 31. At the same time, the right part of the adhesive strip 30 extends to the left side of the right piece 20. That is, the right part of the adhesive strip 30 and the upper surface of the left part of the right piece 20 are pasted together. In this way, when preparing a filter tip, two rod-shaped cellulose acetates are respectively corresponding to the left piece 10 and the right piece 20. Or rather, the left piece 10 is wound around a cellulose acetate rod on the left side, and the right piece 20 is wound around a cellulose acetate rod on the right side. When it is necessary to reduce the resistance of the flue gas passing through, only need to uncover the right part of the adhesive strip 30, then it is very convenient to remove the right piece 20 and the cellulose acetate rod on the relatively right side inside it.

[0018] Optimized:

[0019] The adhesive 32 is not provided on the lower surfaces of the two ends of the base layer 31. That is, both ends of the adhesive strip 30 and the corresponding left piece 10 or right piece 20 are separated, so as to facilitate uncovering the corresponding adhesive strip 30 from the left or from the right.

[0020] The base layer 31 is prepared from a polypropylene film. By weight percentage, the raw material components of the adhesive 32 are: 80 - 90% of aqueous natural latex, and the rest is ethylene-vinyl acetate copolymer emulsion. For example, 80, 85 or 90% of aqueous natural latex, and the rest is ethylene-vinyl acetate copolymer emulsion. Such an adhesive strip 30 is not likely to form a phenomenon that cannot be uncovered with the tipping paper anymore. That is, the adhesive strip 30 is an easily tearable adhesive strip.

[0021] Continue to optimize:

[0022] A set of perforations 11 is provided below each strip of adhesive 30 on the left piece 10, and each set of perforations 11 is in a "U" shape with the opening facing left. That is, when the strip of adhesive 30 is peeled off from left to right, the part of the left piece 10 within the perforations 11 is not easily taken away, and no large opening will be formed; when the strip of adhesive 30 is peeled off from right to left, the part of the left piece 10 within the perforations 11 is very easily taken away, thus forming a relatively large opening. That is to say, the concentration of the smoke can be further adjusted according to the situation, enabling smokers to obtain different smoking experiences.

[0023] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
