Description

Technical Field

[0001] The utility model belongs to the technical field of tissue boxes, and particularly relates to a cutting shell for separating a roll of tissue paper segments. Background Art

[0002] Rolled tissue paper is one of the common daily necessities in life. Usually, the rolled tissue paper is placed on the reel of a tissue box. When extracting the tissue paper, the reel rotates, thereby pulling out the tissue paper. Then, the tissue paper is manually torn off to complete the taking of the tissue paper. However, the occasions for using tissue paper are often not convenient for two-handed operation. It is difficult to tear the tissue paper with only one hand, which causes inconvenience in use.

[0003] Two US patents with publication numbers US2229961A and US4989769A respectively propose a housing for providing a cutting edge. The housing with the cutting edge and the protection device are suitable for laterally cutting a section of tissue paper from the housing, supplying the rolled tissue paper on the housing, and are very effective in cutting polymer sheet layers such as rolled tissue paper. The housing also limits the accidental contact with its cutting edge, thereby greatly limiting the possibility of damage to objects or harm to the users of the equipment with installed blades.

[0004] However, although the above-mentioned disclosed patents can facilitate the cutting of rolled tissue paper, their effects are often not satisfactory. The reason for the poor effect of the outdated method of separating the rolled tissue paper into the required thin sheets is that the cut slices are either serrated, torn or bent, which brings a negative user experience to users, and causes waste of paper or time to a certain extent. People have tried to use cutting tools such as blades, knives and sharper scissors to cut the rolled tissue paper, but these cutting tools are prone to endanger the safety of consumers including children.

[0005] Therefore, a cutting shell for separating a roll of tissue paper segments is needed. A blade is installed below the side of the shell. When the paper is pulled out and passes through the edge of the blade, the paper can be cut by the edge of the blade. In addition, a protection design for the blade is also set on the shell, which limits the accidental contact with its cutting edge. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a cutting shell for separating a roll of tissue paper segments with better cutting effect for the roll of tissue paper segments.

[0007] To solve the above technical problems, the present utility model provides a cutting housing for separating a toilet paper section, including a housing. A toilet paper passage is disposed inside the housing, and the housing has two opposing side edges surrounding the toilet paper passage. The toilet paper passage is used to accommodate toilet paper, and one end of the toilet paper passage has an opening for the toilet paper to pass through. At least one side edge is provided with a cutting passage and a cutting blade. The cutting passage extends along the length direction of the housing and connects the toilet paper passage with the outside of the housing. The cutting blade is disposed in the cutting passage and is used to separate the toilet paper section entering the cutting passage.

[0008] Further, the cutting passage extends along the length direction of the housing from the edge of the side edge to form an opening and a terminal end. Both sides of the cutting passage are open ends, and the two open ends are respectively connected to the toilet paper passage and the outside of the housing.

[0009] Furthermore, the cutting housing further includes a bracket installed at the lower edge of the side edge.

[0010] Furthermore, a groove for installing the cutting blade is formed at a position of the guiding portion close to the terminal end of the cutting passage. The cutting blade is installed in the groove, and the sharp edge of the cutting blade faces the opening of the cutting passage.

[0011] Furthermore, an inclined surface section is provided at one end of the guiding portion close to the opening of the cutting passage. The inclined surface section is used to guide the toilet paper section to enter the cutting passage from the opening of the cutting passage.

[0012] Furthermore, a protective structure is provided on one side of the side edge of the housing. The protective structure is used to block the cutting blade outside the housing.

[0013] Furthermore, the protective structure is a protective portion provided on the side edge. The protective portion extends outward from the side edge and covers the side surface of the cutting passage.

[0014] In addition, the present utility model also provides another cutting housing for separating a toilet paper section. An installation groove is formed on a surface of the side edge away from the toilet paper passage. A blade groove is formed at a position adjacent to the terminal end of the cutting passage in the installation groove. An installation plate is provided in the installation groove.

Specific embodiments

[0029] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Embodiment 1

[0031] As Figures 1 to 3 shown, this embodiment relates to a cutting housing for separating a roll paper section, including a housing 1000. The housing 1000 includes a roll paper channel provided inside it, and two opposite sides 1100 surrounding the roll paper channel. The roll paper channel in this embodiment penetrates the front and rear ends in the length direction of the housing 1, and openings are formed at the front, rear, and lower ends of the roll paper channel. The roll paper channel can accommodate roll paper, and the front opening, rear opening, and lower opening of the roll paper channel can all pass roll paper. A cutting channel 2000 and a cutting blade 1322 are provided on at least one side 1100 of the housing 1000. The cutting channel 2000 extends generally along the length direction of the housing 1000 and communicates the roll paper channel with the outside of the housing 1000. The cutting blade 1322 is disposed in the cutting channel 2000, and the cutting blade 1322 is used to manually separate the roll paper section entering the cutting channel 2000.

[0032] The housing 1000 in this embodiment is generally in an inverted U shape. The housing 1000 can wrap a cylindrical roll paper. A blade is installed below the side 1100 of the housing 1000. The blade is fixedly disposed on the bracket 1300. A gap is formed between the bracket 1300 and the housing 1000, and this gap is the cutting channel 2000. The purpose of setting the cutting channel 2000 is to introduce the roll paper section at the free end of the roll paper. The roll paper section reaches the cutting edge of the cutting blade 1322 through the cutting channel 2000. After pressing down the roll paper section, the roll paper section is cut by the cutting edge and separated from the roll paper in the roll paper channel. The cutting channel 2000 extends generally along the length direction of the housing 1000 and has open two side ends to communicate the roll paper channel with the outside of the housing 1000. In addition, in some other embodiments, the roll paper channel can also be provided with only one or two openings, as long as it is ensured that at least one roll paper channel opening can put roll paper.

[0033] The housing 1000 further includes a connecting portion 1200 connecting two side edges 1100. The connecting portion 1200 and the two side edges 1100 on both sides form a substantially arched shape. The connecting portion 1200 is located between the tops of the two side edges 1100, and the connecting portion 1200 and the two side edges 1100 are integrally formed. The two side edges 1100 are arranged in parallel, and in this embodiment, a gap through which the roll paper can pass is reserved between the two side edges 1100. Cutting channels 2000 and cutting blades 1322 are provided on both side edges 1100, facilitating the user to cut the roll paper in two different left and right directions. Additionally, in some other embodiments, the cutting channels 2000 and the cutting blades 1322 may be provided only on one side edge 1100. Moreover, the above-mentioned connecting portion 1200 may also be detachably connected to the two side edges 1100.

[0034] The cutting channel 2000 extends from the edge of the side edge 1100 substantially along the length direction of the housing 1000 to form an opening and a terminal end. Both sides of the cutting channel 2000 are open ends communicating the roll paper channel with the outside of the housing 1000. The roll paper segment on the free end of the roll paper can pass through the roll paper channel from the two open ends on both sides, or can enter the roll paper channel from the opening of the roll paper channel.

[0035] As Figure 2 and Figure 3 shown, the cutting housing further includes a bracket 1300 installed on the lower edge of the side edge 1100. The bracket 1300 includes a mounting portion 1310 connected to the side edge 1100 and a guiding portion 1320 connected to the mounting portion 1310. The guiding portion 1320 extends outward from the mounting portion 1310 along the length direction of the housing 1000. A certain gap is reserved between the guiding portion 1320 and the side edge 1100 to form the above-mentioned cutting channel 2000. The cutting blade 1322 is installed on the guiding portion 1320.

[0036] A groove 1321 for installing the cutting blade 1322 is formed at a position of the guiding portion 1320 close to the terminal end of the cutting channel 2000. The cutting blade 1322 is installed in the groove 1321, and the sharp edge of the cutting blade 1322 faces the opening of the cutting channel 2000.

[0037] There is an installation column 1120 provided on the lower edge of the side 1100. A slot 1311 for inserting the installation column 1120 is provided on the installation part 1310. The bracket 1300 is installed on the housing 1000 by inserting the installation column 1120 into the slot 1311. In some embodiments (not shown in the figure), the installation column 1120 and the slot 1311 can be set in reverse, that is, the installation column 1120 is provided on the installation part 1310 of the upper bracket 1300, and the slot 1311 is provided on the housing 1000; or the bracket 1300 and the housing 1000 can be realized by setting other connection structures, such as the cooperation of a guide rail and an elastic block, the cooperation of a guide rail and a pin, and threaded connection, etc., which can be used to install the bracket 1300 on the housing 1000. At the same time, in some connection methods, the adjustment of the gap size of the cutting channel 2000 can also be realized.

[0038] By installing the cutting blade 1322 on the bracket 1300 and the bracket 1300 on the housing 1000, it is convenient to replace or maintain the cutting blade 1322 in the bracket 1300 after removing the bracket 1300, making the entire housing 1000 have a longer service life and more convenient maintenance work, and increasing the user experience.

[0039] A protection part 1110 is fixedly provided on the side 1100 away from the paper roll channel. The protection part 1110 extends outward from the side 1100 to cover the side of the cutting channel 2000 to limit the contact between the user's finger and the cutting blade 1322. The protection part 1110 is provided on the side of the side 1100 away from the paper roll channel; the protection part 1110 protrudes and extends from the side 1100 and covers the side of the cutting channel 2000. Generally, the user's finger approaches the housing 1000 from the side or the front end of the housing 1000. No matter approaching the cutting channel 2000 from the side or the front end of the housing 1000, especially when moving along the direction of the cutting channel 2000, the protection part 1110 is in this direction and forms a block. This block limits the user's finger from approaching the cutting blade 1322 from the direction facing the sharp edge of the cutting blade 1322, playing a protective role to prevent the user from being cut by the blade during use and affecting the use experience.

[0040] One end of the guiding part 1320 close to the opening of the cutting channel 2000 is provided with an inclined surface section 1340. The inclined surface section 1340 is used to facilitate the paper roll section to enter the cutting channel 2000 from the opening of the cutting channel 2000. The setting of the inclined surface section 1340 makes it easier for the cutting channel 2000 to receive the paper roll section from the opening.

[0041] Embodiment 2

[0042] Such as Figures 4 to 7As shown, this embodiment relates to another cutting shell for separating roll paper segments, including a shell 1000, the shell 1000 includes a roll paper channel running through the front and rear ends of the shell 1000 in the longitudinal direction and two opposite side edges 1100 surrounding the roll paper channel, the roll paper channel can accommodate the roll paper and the opening at one end thereof can pass the roll paper, at least one side edge 1100 is provided with a cutting channel 2000 and a cutting blade 1322, the cutting channel 2000 extends roughly along the longitudinal direction of the shell 1000 and connects the roll paper channel with the outside of the shell 1000, the cutting blade 1322 is arranged in the cutting channel 2000 for manually separating the roll paper segments entering the cutting channel 2000.

[0043] The housing 1000 also includes a connecting portion 1200 connecting the two side edges 1100. The connecting portion 1200 and the side edges 1100 on both sides form a roughly arched shape. The two side edges 1100 are arranged in parallel, and a gap is retained between the two side edges 1100 to allow the passage of a paper roll. Each side edge 1100 is provided with a cutting channel 2000 and a cutting blade 1322. The cutting channel 2000 extends from the edge of the side edge 1100 roughly along the length of the housing 1000 to form an opening and an end. The two sides of the cutting channel 2000 are open ends connecting the paper roll channel with the exterior of the housing 1000. The paper roll section at the free end of the paper roll can pass through the paper roll channel through the open ends on both sides, or enter the paper roll channel through the paper roll channel opening.

[0044] The difference between this embodiment and the previous embodiment is that:

[0045] like Figures 4 to 7 As shown, a mounting groove 1550 is defined on the side of the side 1100 away from the paper roll passage. A blade groove 1560 is defined in the mounting groove 1550 adjacent to the end of the cutting passage 2000. A mounting plate 1600 is secured within the mounting groove 1550. The mounting groove 1550 presses the cutting blade 1322 against the blade groove 1560 via the mounting plate 1600. The sharp edge of the cutting blade 1322 is positioned within the cutting passage 2000 and faces the opening of the cutting passage 2000. It should be noted that, in this embodiment, both side edges 1100 are defined with mounting grooves 1550. In other embodiments, the mounting groove 1550 may be defined on only one of the side edges 1100.

[0046] On one side of the mounting plate 1600 away from the paper roll channel, a protective plate 1610 is fixedly installed. The protective plate 1610 extends outward from the mounting plate 1600 to cover the side surface of the cutting channel 2000, so as to limit the contact between the user's finger and the cutting blade 1322. The protective plate 1610 protrudes and extends from the side edge 1100 and covers the side surface of the cutting channel 2000. Generally, the user's finger approaches the housing 1000 from the side or the front end of the housing 1000. No matter when approaching the cutting channel 2000 from the side or the front end of the housing 1000, especially when moving along the direction of the cutting channel 2000, the protective plate 1610 is in this direction and forms a barrier. This barrier restricts the user's finger from approaching the cutting blade 1322 from the direction facing the sharp edge of the cutting blade 1322, playing a protective role to prevent the user from being cut by the blade during use and affecting the use experience. The protective plate 1610 in this embodiment and the protective part 1110 in the first embodiment are two protective structures for blocking the cutting blade 1322 outside the housing 1000, and both can provide protection for the user's safety.

[0047] The opening of the cutting channel 2000 is arranged on the edge of the side edge 1100 near the front end of the housing 1000. An inclined surface 1570 is provided at the opening of the cutting channel 2000. The inclined surface 1570 is used to facilitate the paper roll section to enter the cutting channel 2000 from the opening of the cutting channel 2000. The setting of the inclined surface 1570 makes it easier for the cutting channel 2000 to receive the paper roll section from the opening.

[0048] A connecting rib 1580 is formed on the side edge 1100 in the mounting groove 1550, and a connecting groove 1620 adapted to the connecting rib 1580 is provided on the mounting plate 1600. In some embodiments (not shown in the figure), the connecting rib 1580 and the connecting groove 1620 can be arranged in reverse, that is, the connecting rib 1580 is arranged on the mounting plate 1600 and the connecting groove 1620 is arranged on the housing 1000. Or the mounting plate 1600 and the housing 1000 can be connected by other connecting structures not limited to being clamped with the mounting groove 1550, such as magnetic attraction and threaded connection, etc., which can be used to install the mounting plate 1600 to the housing 1000, and at the same time press the cutting blade 1322 in the blade groove 1560.

[0049] In this embodiment, the sharp edge of the cutting blade 1322 is obliquely arranged relative to the horizontal plane, and its facing direction is above the opening. By installing the cutting blade 1322 into the blade groove 1560 and installing the mounting plate 1600 into the mounting groove 1550 to press the cutting blade 1322, the cutting blade 1322 can be set to face obliquely downward at the opening of the cutting channel 2000, so that the setting height of the cutting housing can be relatively low.

[0050] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model.
