DETAILED DESCRIPTION
[0044] The preferred embodiment of the utility model is described below in conjunction with the accompanying drawings. It should be understood that the environmentally friendly plastic bucket with anti-sticking bucket function described here is a preferred embodiment, which is only used to illustrate and explain the utility model and does not constitute a limitation of the utility model.
[0045] The directional words or positional relationships such as "up", "down", "left" and "right" described in the embodiments are based on the human body position when using the embodiments and are only for the convenience of describing the utility model and simplifying the description. They do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the content protected by the utility model.
[0046] Example 1
[0047] like Figures 1 to 12 As shown, this embodiment includes a barrel body 1, a barrel cover 2, an isolating member and a fixing member, wherein the barrel body 1 includes a barrel body 102 and a barrel mouth 101; the barrel cover 2 is detachably arranged at the barrel mouth 101; the isolating member is sleeved in the barrel body 1 for containing materials so as to separate the materials from the inner wall of the barrel body 1; the fixing member is arranged between the barrel mouth 101 and the barrel cover 2, and the fixing member is detachably connected to the barrel mouth 101, and is used to fix the protruding end of the isolating member at the barrel mouth 101 to prevent the isolating member from detaching from the barrel body 1 when pouring materials.
[0048] like Figure 2 As shown, in this embodiment, the spacer is a plastic bag 3, and its size is adapted to the internal size of the barrel body 1. Adaptation here means that the lateral size of the plastic bag 3 is equal to the internal size of the barrel body 1, so that the plastic bag 3 can be completely placed in the barrel body 1. The lateral direction here refers to the left and right directions. At the same time, the height of the plastic bag 3 is greater than the height of the barrel body 1, so that the bag opening 31 can extend from the barrel body 1 and overlap the edge of the barrel opening 101. The extended end of the spacer is the position of the bag opening 31 of the plastic bag 3. Figure 2 , Figure 3 As shown, when in use, the plastic bag 3 is sleeved in the barrel body 1, the bag opening 31 extends from the barrel body 1 and overlaps the edge of the barrel opening 101, and the bag opening 31 is clamped to the barrel opening 101 by a fixing member to prevent the plastic bag 3 from escaping from the barrel opening 101 and being poured out with the material when pouring. The isolation member in this embodiment can also be selected to be a bag body made of aluminum foil material.
[0049] like Figure 3 , Figure 7 As shown, the fixing member is a barrel mouth ring 4, and the barrel mouth ring 4 includes an inner ring 41 and an outer ring 42 which are fixedly connected. The inner ring 41 contacts the inner wall of the barrel mouth 101, and the outer ring 42 contacts the outer wall of the barrel mouth 101. There is a clamping space 44 between the inner ring 41 and the outer ring 42 for clamping the barrel mouth 101, see Fig.10 , 11The size of the clamping space 44 is adapted to the thickness of the barrel mouth 101. Adaptation here means that the width of the clamping space 44 is slightly smaller than the thickness of the barrel mouth 101, so that the barrel mouth ring 4 can be firmly clamped with the barrel mouth 101. Figure 2 , 3 As shown, the bag opening 31 overlaps the upper edge of the barrel opening 101. When the barrel opening ring 4 is clamped on the barrel opening 101 from top to bottom, the bag opening 31 can be clamped between the upper edge of the barrel opening 101 and the barrel opening ring 4. The fixing member in this embodiment can also be a wire, which is used to wrap around the barrel opening 101 to fasten the bag opening 31 to the outer wall of the barrel opening 101. When pouring materials, the barrel opening 101 faces downward, and the plastic bag 3 and the materials are poured out of the barrel body 1 together. See Fig.12 , but the bag mouth 31 of the plastic bag 3 is pressed against the barrel mouth 101 by the barrel mouth ring 4, and the barrel mouth ring 4 and the barrel mouth 101 are firmly connected, so the barrel mouth ring 4 will not fall off from the barrel mouth 101, ensuring that the plastic bag 3 will not separate from the barrel body 1 when pouring the material, and the material will be poured out smoothly. After pouring the material, the residual material will adhere to the plastic bag 3, but will not adhere to the inner wall of the barrel body 1. The plastic barrel is always clean and can be reused after replacing the plastic bag 3, thereby reducing the production links after the waste barrel is recycled, which is more environmentally friendly.
[0050] In order to ensure that the plastic bag 3 can be poured out of the barrel 1 smoothly when pouring the material, Figure 2 , 3 As shown, in this embodiment, a plurality of first air holes 5 are provided at the barrel mouth 101. The plurality of first air holes 5 penetrate the barrel mouth wall and are arranged at intervals along the circumference of the barrel mouth 101. This structure facilitates air to enter between the inner wall of the barrel body 1 and the plastic bag 3, so that the air pressure between the inner wall of the barrel body 1 and the plastic bag 3 is balanced with the external air pressure, which facilitates the pouring out of the plastic bag 3 and prevents the plastic bag 3 from being adsorbed on the inner wall of the barrel body 1 and being inconvenient to pour out. Furthermore, a ventilation structure for allowing air to enter between the inner wall of the barrel body 1 and the isolation member through the first air holes 5 is provided on the barrel mouth ring 4. In this embodiment, the ventilation structure is a second air hole 43 provided at a position corresponding to the first air hole 5 on the barrel mouth ring 4. In this embodiment, the height of the inner ring 41 is less than the height of the outer ring 42, so only the second air hole 43 is provided on the outer ring 42. There are also a plurality of second air holes 43, which are arranged at intervals along the circumference of the outer ring 42. It should be noted that in order to ensure that air can enter between the inner wall of the barrel body 1 and the plastic bag 3, the bag opening 31 of the plastic bag 3 cannot cover the first air hole 5, otherwise the plastic bag 3 will affect the entry of air after the barrel opening ring 4 is fixed.
[0051] In order to further ensure that the barrel mouth ring 4 is firmly connected with the barrel mouth 101, a circle of protrusions 6 is arranged on the outer wall of the barrel mouth 101 along its circumference, see Figure 3-8 Correspondingly, a block 7 is provided at a position corresponding to the protrusion 6 on the inner side of the outer ring 42 of the barrel mouth ring 4, and the longitudinal section of the block 7 is a triangle; Figure 6As shown, the block 7 abuts against the lower edge of the protrusion 6; Figure 6 , 8 As shown, in this embodiment, the working end 8 of the clamp block refers to the top angle position, and the working end 8 of the clamp block contacts the side wall of the barrel mouth 101. When pouring, the barrel mouth 101 faces downward, but the clamp block 7 abuts against the lower edge of the protrusion 6, and the protrusion 6 can prevent the barrel mouth ring 4 from separating from the barrel mouth 101, thereby ensuring that the bag mouth 31 is always clamped at the barrel mouth 101. Figure 7 , 8 As shown in Figures 10 and 11, the outer ring 42 of the barrel mouth ring 4 is a split structure. The outer ring 42 includes a plurality of arc-shaped pieces 421 arranged at intervals along the circumference of the barrel mouth 101. Each arc-shaped piece 421 is bent toward the central axis of the barrel body 1 and is movably connected to the inner ring 41. Each arc-shaped piece 421 is provided with a block 7 adapted to the protrusion 6, and there is no contact between any two adjacent arc-shaped pieces 421. When the plastic bag 3 needs to be replaced, the plurality of arc-shaped pieces 421 are directly opened in the direction away from the central axis of the barrel body 1, and then the barrel mouth ring 4 is removed. In this embodiment, the second air hole 43 includes two semicircular holes, which are arranged on two adjacent arc-shaped pieces 421. The two semicircular holes are arranged relative to each other to form a circular hole. In this embodiment, the longitudinal section of the block 7 can also be adjusted to an arc or other shape, as long as it can abut against the protrusion 6.
[0052] In order to improve this embodiment, Figure 2 , 3 As shown in Figures 5, a circle of reinforcing ribs 9 are arranged around the barrel body 1 along its circumference for reinforcing the barrel body 102 to prevent the barrel body 102 from being deformed after repeated use. The structure of the reinforcing ribs 9 is prior art and will not be described in detail here. In this embodiment, grooves are provided on the reinforcing ribs 9 to enhance the overall aesthetics of the plastic barrel.
[0053] The barrel cover 2 and the barrel mouth ring 4 are detachably connected. In the present embodiment, the barrel cover 2 and the barrel mouth ring 4 are threadedly connected, and the barrel mouth ring 4 is sleeved in the barrel cover 2. Of course, a snap-on connection can also be selected. Both threaded connection and snap-on connection are prior arts and will not be described in detail here.
[0054] In this embodiment, the plastic barrel is made of plastic material. Figure 5 , 6 The section lines in 10 and 11 are oblique lines, and the section lines here do not constitute a limitation on the material.
[0055] When using this embodiment, the material enters the plastic bag 3 during loading, and when emptying the material, Fig.12As shown, the barrel mouth 101 faces downward, and the plastic bag 3 leaves the barrel body 1 together with the material, but the bag mouth 31 of the plastic bag 3 is still clamped at the barrel mouth 101. After the material is poured, the viscous paste material will adhere to the plastic bag 3. At this time, the barrel mouth ring 4 can be removed and the plastic bag 3 can be replaced, which saves time and effort. There is no need to clean the inner wall of the barrel body 1. The plastic barrel is still in a clean state and can be reused, reducing the cost of use.
[0056] Example 2
[0057] like Figure 13-20 As shown, the structure of this embodiment is basically the same as that of embodiment 1, except that:
[0058] 1. The fixing method of the barrel cover 2;
[0059] In this embodiment, the barrel cover 2 is detachably arranged on the barrel body 1. The barrel body 1 is provided with a socket 10, and the shape of the socket 10 is an isosceles trapezoid, such as Fig.14 , 16 As shown, the edges of the barrel ring 4 and the barrel cover 2 are provided with a notch 11 that is compatible with the plug-in seat 10. The notch 11 is also an isosceles trapezoid. A plug-in block 12 is provided at the bottom of the notch 11. Here, the bottom of the notch 11 refers to the position where the notch 11 is away from the barrel body 1. The plug-in seat 10 is provided with a slot 13 at the position corresponding to the plug-in block 12. The size of the slot 13 is compatible with the size of the plug-in block 12. The plug-in block 12 is snapped into the plug-in seat 10. Here, the adaptation means that the height of the slot 13 is equal to the height of the plug-in block 12 to ensure that the plug-in block 12 can be inserted, and the width of the slot 13 is greater than the width of the plug-in block 12. Here, the height refers to the distance in the up and down directions, and the width refers to the distance in the left and right directions. The specific way in which the plug-in block 12 is snapped into the plug-in seat 10 is as follows: Fig.14 , 17 -20, an opening 15 is provided at a position corresponding to the slot 13 on the plug-in seat 10, and a protrusion 16 with a triangular longitudinal section is provided on the plug-in block 12. After the plug-in block 12 is inserted into the slot 13, the protrusion 16 extends into the opening 15. At the same time, the protrusion 16 abuts against the upper edge of the plug-in seat 10 to fix the barrel cover 2. After the barrel cover 2 is fixed, the barrel mouth ring 4 is sleeved in the barrel cover 2. A card slot for the edge of the barrel mouth 101 to be inserted is provided inside the barrel cover 2. This structure is a prior art. When the barrel cover 2 needs to be opened, the plug-in block 12 is pressed in the direction of the central axis of the barrel body 1, and the protrusion 16 enters the slot 13. At this time, the protrusion 16 does not abut against the upper edge of the plug-in seat 10, and the barrel cover 2 can be lifted upward, and then the barrel cover 2 is opened with force to make the barrel mouth 101 disengage from the card slot on the barrel cover 2.
[0060] Of course, the barrel cover 2 and the barrel body 1 can also be connected in another way, such as providing a plug-in block and a protrusion on the barrel cover 2, and only providing a slot adapted thereto on the barrel body 1, and when the plug-in block is inserted into the slot, the protrusion is connected to the slot. Since this method is a prior art, it will not be described in detail in this embodiment.
[0061] For beauty, such as Fig.16 As shown, a baffle 14 is provided at the opening 15, and the baffle 14 is connected to the socket 10 through a connecting rod 17. The connecting rod 17 is made of plastic and is relatively thin, so it can be connected along Fig.18 The blocking piece 14 is turned over in the direction of the middle arrow. When the barrel cover 2 needs to be opened, the blocking piece 14 is first turned over, and then the plug-in block 12 is pressed.
[0062] 2. Ventilation structure;
[0063] like Fig.15 As shown, in this embodiment, the block 7 on the barrel mouth ring 4 is still abutted against the lower edge of the protrusion 6, and a gap 18 is provided between the abutting working position of the outer ring 42 and the side wall of the barrel mouth 101. In this embodiment, the gap 18 is a ventilation structure. Here, the abutting working position of the outer ring 42 refers to the area between the block 7 on the outer ring 42 and the bottom of the outer ring 42. Since the first air hole is located below the protrusion 6, air enters from the bottom of the outer ring 42 and then enters into the space between the inner wall of the barrel body and the plastic bag through the first air hole, and there is no need to provide a second air hole on the barrel mouth ring 4.
[0064] It should be noted that, without setting the second air hole and the gap 18, air can be passed through in another way, that is, the gap between two adjacent arc-shaped pieces on the barrel mouth ring 4 is used as a ventilation structure. As long as the barrel mouth ring 4 is fixed on the barrel mouth 101, the gap between the arc-shaped pieces is aligned with the first air hole to achieve air passage.
[0065] 3. Reinforcement ribs 9;
[0066] like Fig.14 As shown, the difference between the reinforcing rib 9 on the barrel body 102 and that in the first embodiment is that no groove is provided on the reinforcing rib 9 in the present embodiment.
[0067] In addition, the connection method between the barrel mouth ring 4 and the barrel mouth 101 and the structure of the isolation piece are exactly the same as those in Example 1 and will not be elaborated in detail in this embodiment.
[0068] The usage process of this embodiment refers to Embodiment 1.
[0069] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
