Description

Technical Field

[0001] The present invention relates to the technical field of article storage, and in particular to a soft bag set and device for storing articles that are convenient for continuous unfolding and opening for use. Background Art

[0002] A storage bag is a tool for organizing and storing articles, usually made of soft materials such as plastics, non-woven fabrics, nylons, polyesters, etc. They can be designed in various sizes, shapes, and materials according to different uses and requirements.

[0003] Storage bags are classified by use and include clothing storage bags for organizing clothes, shoes, hats, etc., document storage bags for storing documents, materials, bills, etc., kitchen storage bags for storing food, seasonings, tableware, etc., and garbage storage bags for storing garbage.

[0004] When a storage bag is used to store and collect garbage, such as in the Chinese utility model patent with the application number 201921550416.5 and the name of a garbage bag, a garbage bag product, and a trash can applied to the garbage bag, the garbage bag is put on from the bag inlet, and the upper guiding part of the garbage bag is opened and respectively put into the guide rails. By setting a deformation seam, the mouth of the bag body can be conveniently opened, and then the garbage bag is pulled towards the side of the discharge port until the garbage bag is completely inside the trash can; when the garbage bag needs to be replaced, the garbage bag is pulled towards the side of the bag outlet, and the garbage bag is pulled out from the bag outlet to replace it with a new garbage bag.

[0005] When the above storage bag is applied to the storage and collection of garbage and other storage items, the storage items can be gathered in a containing cavity. When the storage items reach the containing value of the containing cavity, a new storage bag is manually placed again to carry new storage items, which not only reduces the efficiency of replacing the storage bag but also reduces the efficiency of collecting the storage items.

[0006] Based on this, a soft bag set and device for storing articles that are convenient for continuous unfolding and opening for use are designed. Summary of the Invention

[0007] The present invention aims to overcome the above-mentioned defects in the prior art and provides a soft bag set and device for storing articles that are convenient for continuous unfolding and opening for use. Only by placing the soft bag set for storing articles once can multiple storage, collection, and processing of different quantities of storage items be completed, which not only improves the efficiency of replacing the storage bag but also improves the efficiency of collecting the storage items.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is as follows: an article storage soft bag group that is convenient for continuous unfolding and opening use, including a plurality of paper or plastic storage bags connected together in sequence.

The opening includes two mutually separated lips, and a bag tube connected to the lip is provided on each lip, which is formed by surrounding with a soft material to form an installation cavity. The installation cavities of the bag tubes on the same side lips of the adjacent two storage bags communicate with each other, and the separation structure passes through the bag tube.

[0009] A device for unfolding the above-mentioned article storage soft bag group includes a three-dimensional frame with an internal volume capable of accommodating at least one unfolded storage bag. A guide rod for passing through the installation cavity of the storage bag is provided at the upper part of the frame. The guide rod includes an insertion end for inserting into the bag tube when starting to use the soft bag group and a detachment end for detaching the bag tube from the guide rod when one storage bag is used up. A support frame for supporting the above-mentioned guide rod is also provided at the upper part of the frame. The support frame includes a support frame entrance for introducing the bag tube, a support frame exit for detaching the bag tube, and a limit structure for preventing the guide rod from moving away from the support frame exit. A rolling component for generating rolling friction between the bag tube and at least one of the guide rod and the support frame when pulling the bag tube to move along the guide rod is provided on the guide rod and / or the support frame. A communication groove allowing the lip of the storage bag to pass through and continuously move along the guiding direction of the guide rod is opened at the lower end of the support frame, and the size of the communication groove is such that the guide rod cannot enter or pass through.

[0010] As a preferred solution of the present invention, there are two support frames, and the two support frames are arranged oppositely and fixed on the frame.

[0011] As a preferred solution of the present invention, there are two support frames, and two slide rails perpendicular to the support frames are further provided on the frame. The slide rails are fixed at the upper end of the frame, and both ends of the support frame are slidably arranged on the slide rails. An elastic structure for pulling at least one support frame to slide along the slide rail so that the two oppositely arranged support frames approach or move away from each other is also provided on the frame.

[0012] As a preferred solution of the present invention, a plurality of notches for reducing the weight of the support frame and thus facilitating the movement of the support frame along the slide rail are formed on the side of the support frame away from the storage bag, and the notches are arranged in an array on the side surface of the support frame.

[0013] As a preferred solution of the present invention, the limiting structure includes a limiting roller arranged at the upper end of the support frame and located above the guide rod, and the disengagement end of the guide rod has a smooth height-dropping end surface. When the bag tube is pulled, the limiting roller can be abutted against the height-dropping end surface to limit the guide rod from detaching from the support frame.

[0014] As a preferred solution of the present invention, the rolling assembly includes a first rolling assembly located on a side of the support frame close to the storage bag and generating rolling friction with the moving bag tube, and the first rolling assembly is arranged opposite to the limiting structure.

[0015] As a preferred solution of the present invention, the rolling assembly includes a second rolling assembly located at both ends of the guide rod and generating rolling friction with the moving bag tube.

[0016] As a preferred solution of the present invention, the upper end of the support frame is provided with a connecting groove that allows the lip of the storage bag to pass through and move continuously along the guide direction of the guide rod. The size of the connecting groove is sufficient to prevent the guide rod from entering or passing through.

[0017] As a preferred solution of the present invention, a side of the support frame close to the storage bag is provided with an arc surface for guiding the bag tube to enter the support frame inlet or guide the bag tube to leave the support frame outlet.

[0018] The beneficial effects of the present invention are: 1. The bag tubes of adjacent storage bags of the present invention are connected in sequence.

[0020] 3. The present invention realizes the pulling out of the storage bag once through the cooperation between the frame, the guide rod and the support frame, that is, the replacement between adjacent storage bags can be realized and the storage bag can be opened automatically, which is convenient for the collection and processing of daily storage items.

[0021] 4. The present invention can realize multiple collection of storage items through the cooperation between the frame, the guide rod and the support frame, without having to reinstall the storage bag multiple times, thereby improving the efficiency of storage item collection.

[0022] 5. In the present invention, the first rolling assembly, the second rolling assembly and the limiting roller generate rolling friction with the bag tube entering or leaving the support frame, which not only plays a guiding role, but also helps the storage bags to quickly enter or leave the relative support frame, so that adjacent storage bags can be quickly replaced, thereby improving the efficiency of storage bag replacement.

[0023] 6. The arc surface of the present invention guides the bag tube, which can fit the bag tube better than a plane or a sharp corner, making it smoother for the bag tube to enter the entrance of the support frame or exit the exit of the support frame, avoiding damage to the bag tube, and improving the safety of replacing the storage bag.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following will describe the embodiments of the present invention in detail with reference to the drawings.

[0029] As Figure 8 shown, an article storage soft bag set facilitating continuous unfolding and opening for use includes a plurality of paper or plastic storage bags 1 connected together in sequence. The storage bag 1 includes two opposite side sealing edges 11 and a bottom sealing edge 12. One side sealing edge 11 of one of the adjacent storage bags 1 and the side sealing edge 11 of the other storage bag 1 are integrally formed to achieve the above connection, and a separation structure 14 for separating the adjacent side sealing edges 11 is provided at the connection; an opening 13 is provided on the side opposite to the bottom sealing edge 12 of the storage bag 1. The opening 13 includes two mutually separated lip edges 131. A bag tube 15 connected to the lip edge 131 is provided on each lip edge 131 after a mounting cavity 151 is formed by surrounding with a soft material. The mounting cavities 151 of the bag tubes 15 on the same side lip edges 131 of two adjacent storage bags 1 communicate with each other, and the separation structure 14 passes through the bag tube 15.

[0030] For specifically using the above article storage soft bag set: Place the article storage soft bag set inside the frame 2, and sleuth the bag tube 15 of the first storage bag 1 in the article storage soft bag set outside the guide rod 3, that is, the guide rod 3 is covered in the mounting cavity 151 of the bag tube 15, and then place the guide rod 3 in the support frame 4. Correspondingly, the first storage bag 1 is located between two opposite support frames 4; when the first storage bag 1 carries an appropriate amount of stored items inside, pull the side of the first storage bag 1 away from the article storage soft bag set. The bag tube 15 of the first storage bag 1 leaves the guide rod 3 under the action of the pulling force, and the bag tube 15 of the next storage bag 1 enters the inside of the support frame 4 under the guiding action of the guide rod 3. Correspondingly, the next storage bag 1 is located between two opposite support frames 4. Further, separate the first storage bag 1 from the next storage bag 1 through the separation structure 14 to complete the replacement between adjacent storage bags 1.

[0031] Similarly, the replacement between other adjacent storage bags 1 is the same as the replacement between the above storage bags 1; thus, several storage bags 1 constituting the article storage soft bag set can be continuously extracted and used inside the frame 2.

[0032] In the present invention, the bag tubes 15 of adjacent storage bags 1 communicate with each other in sequence. By pulling the side of the storage bag 1 away from the article storage soft bag set, the replacement between adjacent storage bags 1 can be realized, which is convenient for the replacement of the storage bags 1 and improves the replacement efficiency of the storage bags 1.

[0033] In the present invention, a separation structure 14 is provided between adjacent storage bags 1, which is convenient for separating the storage bags 1 after replacement and can realize the rapid processing of the stored items inside the storage bags 1.

[0034] Embodiment 1: As Figures 1-4As shown in the figure, a device for unfolding the above-mentioned soft bag set for item storage includes a three-dimensional frame 2 with an internal volume capable of accommodating at least one storage bag after unfolding. A guide rod 3 is provided at the upper part of the frame 2 and is used to pass through the installation cavity 151 of the storage bag. The guide rod 3 includes an insertion end 31 for inserting into the bag tube when initially using the soft bag set, and a separation end 32 for separating the bag tube from the guide rod 3 when a storage bag is used up. The upper part of the frame 2 is also provided with a support frame 4 for supporting the above-mentioned guide rod 3. The support frame 4 includes a support frame inlet 41 for introducing the bag tube, a support frame outlet 42 for separating the bag tube, and a limiting structure 43 for preventing the guide rod 3 from moving away from the support frame outlet 42. A rolling component is provided on the guide rod 3 and / or the support frame 4, which can cause rolling friction between the bag tube and at least one of the guide rod 3 and the support frame 4 when pulling the bag tube to move along the guide rod 3. A communication groove 44 is opened at the lower end of the support frame 4, allowing the lip of the storage bag to pass through and move continuously along the guiding direction of the guide rod 3. The size of the communication groove 44 is sufficient to prevent the guide rod 3 from entering or passing through.

[0035] There are two support frames 4, and the two support frames 4 are arranged opposite to each other and fixed on the frame 2. Correspondingly, a certain distance is spaced between the two support frames 4.

[0036] Specifically, after the current storage bag 1 carries an appropriate amount of stored items, pull the current storage bag 1 away from one side of the soft bag set for item storage. The bag tube 15 of the current storage bag 1 is disengaged from the separation end 32 under the guiding action of the guide rod 3. At the same time, it is also disengaged from the support frame outlet 42 of the support frame 4. The lip 131 of the current storage bag 1 also leaves the support frame 4 through the communication groove 44. Thus, the current storage bag 1 is disengaged from the two opposite support frames 4, and the guide rod 3 is restricted in the support frame 4 by the limiting action of the limiting structure 43 at the support frame outlet 42 and will not be disengaged from the support frame outlet 42. The bag tube 15 of the next storage bag 1 is sleeved outside the guide rod 3 through the insertion end 31. At the same time, the bag tube 15 of the next storage bag 1 enters the inside of the support frame 4 through the support frame inlet 41. The lip 131 of the next storage bag 1 also enters the support frame 4 through the communication groove 44. Thus, the next storage bag 1 is located between the two opposite support frames 4. Since a certain distance is spaced between the two opposite support frames 4, after the next storage bag 1 enters the opposite support frame 4, the opening for receiving stored items will automatically open and start receiving new stored items. During the replacement process of the current storage bag 1 and the next storage bag 1, the rolling friction exerted by the rolling component on the bag tube 15 located on the guide rod 3 and / or the support frame 4 is beneficial to the quick entry or exit of the storage bag 1 from the opposite support frame 4, improving the replacement efficiency between adjacent storage bags 1.

[0037] Among them, the connecting groove 44 is located at the lower end of the support frame 4. Correspondingly, the bag cylinder 15 is replaced and located at the lower end of the support frame 4, and it will not interfere with the structure located at the upper end of the support frame 4, thereby ensuring the stable and safe replacement between the storage bags 1. The distance between two opposite support frames 4 fixed on the frame 2 is certain. Therefore, when the storage bag 1 enters and is located between the two support frames 4, the opening sizes of the sides for receiving the stored items are the same.

[0038] Furthermore, the rolling assembly includes a first rolling assembly 7 located on the side of the support frame 4 close to the storage bag and generating rolling friction with the moving bag cylinder. The first rolling assembly is arranged opposite to the limiting structure 43. At the same time, the above-mentioned first rolling assembly 7 and limiting structure 43 can not only be arranged at the support frame outlet 42, but also one of them or both can be arranged at the support frame inlet 41. The limiting structure 43 located at the support frame inlet 41 prevents the guide rod 3 from disengaging from the support frame inlet 41.

[0039] The above-mentioned limiting structure 43 is preferably a limiting roller.

[0040] The rolling assembly includes a second rolling assembly 8 located at both ends of the guide rod 3 and generating rolling friction with the moving bag cylinder.

[0041] The above-mentioned first rolling assembly 7 and second rolling assembly 8 can be arranged in the support frame 4 and the guide rod 3 at the same time, or one of them can be arranged in the support frame 4 or the guide rod 3.

[0042] Specifically, when the guide rod 3 guides and supports the bag cylinder 15 and enables adjacent bag cylinders 15 to be replaced in the support frame 4, the first rolling assembly 7 located in the support frame 4, the second rolling assembly 8 located on the guide rod 3, and the limiting roller generate rolling friction with the bag cylinder 15 entering or leaving the support frame 4. While playing a guiding role, it is beneficial for the storage bag 1 to quickly enter or leave the opposite support frame 4.

[0043] Furthermore, an arc surface 46 for guiding the bag cylinder 15 to enter the support frame inlet 41 or exit the support frame outlet 42 is provided on the side of the support frame 4 close to the storage bag. The arc surface 46 is closer to the inside of the support frame 4 than the first rolling assembly 7. The arc surface 46 guides the bag cylinder 15 and can fit the bag cylinder 15 better than a plane or a sharp corner, making it smoother for the bag cylinder 15 to enter the support frame inlet 41 or exit the support frame outlet 42 and avoiding damage to the bag cylinder 15.

[0044] The support frame 4 in the present invention can be an integrally formed structure or assembled from multiple components. The integrally formed support frame 4 is convenient for actual processing, and the support frame 4 assembled from multiple components is convenient for the installation of the internal guide rod 3.

[0045] Through the cooperation among the frame 2, the guide rod 3 and the support frame 4, the present invention realizes that by pulling the storage bag 1 once, the replacement between adjacent storage bags 1 can be achieved and the storage bag 1 can automatically open, facilitating the collection and handling of daily storage items.

[0046] Through the cooperation among the frame 2, the guide rod 3 and the support frame 4, the present invention can achieve multiple collections of storage items without reinstalling the storage bag multiple times, improving the efficiency of collecting storage items.

[0047] Embodiment Two: As Figure 5 shown, the difference between Embodiment Two and Embodiment One is that the support frame 4 is not fixed to the frame 2.

[0048] There are two support frames 4, and two slide rails 5 perpendicular to the support frame 4 are further arranged on the frame 2. The slide rails 5 are fixed at the upper end of the frame 2, and both ends of the support frame 4 are slidably arranged on the slide rails 5. An elastic structure 6 is further arranged on the frame 2 for pulling at least one support frame 4 to slide along the slide rail 5 so that the two relatively arranged support frames 4 approach or move away from each other.

[0049] In the present invention, the elastic structure 6 includes an elastic member, and the elastic member is preferably a spring.

[0050] Several notches 45 for reducing the weight of the support frame 4 and thus facilitating the movement of the support frame 4 along the slide rail 5 are formed on the side of the support frame 4 away from the storage bag 1, and the notches 45 are arranged in an array on the side surface of the support frame 4.

[0051] Specifically, when pulling the side of the storage bag 1 away from the item storage soft bag group, the pulling force is decomposed into two forces. One force acts on the bag tube 15, causing the bag tube 15 to leave the support frame 4 under the guiding action of the guide rod 3. Further, the bag tube 15 of the next storage bag 1 enters the support frame 4 under the guiding action of the guide rod 3, and the next storage bag 1 is located between the two relatively arranged support frames 4. The other force acts on the support frame 4, enabling the support frame 4 to move in a straight line closer along the slide rail 5 and under the guiding action of the slide rail 5. At the same time, the spring in the elastic structure 6 is stretched by the pulling force in the same direction, and correspondingly, the stretched spring exerts a reverse acting force, causing the support frame 4 to move in a straight line away along the length direction of the slide rail 5, and thus the opening of the storage bag 1 is opened.

[0052] Compared with Embodiment One, in Embodiment Two, the opening size of the side of the storage bag 1 for receiving storage items is realized by the spring force. Further, the opening of different sizes of the storage bag 1 can be adjusted by adjusting the spring force, and the applicable range is wider.

[0053] Through the movable connection between the support frame 4 and the frame 2, the present invention can open openings of different sizes for storage bags 1 of various sizes, and has a wider applicable range.

[0054] Embodiment Three: As Figure 6 shown, the difference between Embodiment Three and Embodiments One and Two is that the position of the through groove 44 in the support frame 4 is different.

[0055] A communication groove 44 allowing the lip of the storage bag to pass through and capable of continuously moving along the guiding direction of the guiding rod 3 is opened at the upper end of the support frame 4, and the size of the communication groove 44 is such that the guiding rod cannot enter or pass through.

[0056] Specifically, after the bag tubes 15 on both sides of the current storage bag 1 are respectively sleeved outside the guiding rod 3 and the guiding rod 3 is installed in two oppositely arranged support frames 4, since the through groove 44 is located at the top of the support frame 4, it is clearly visible whether the bag tubes 15 and the guiding rod 3 are installed in place in this step, facilitating the installation of the bag tubes 15 and the guiding rod 3 in the support frame 4; When the side of the storage bag 1 away from the article storage soft bag group is pulled, the bag tube 15 of the current storage bag 1 leaves the support frame 4 under the action of the pulling force, or the bag tube 15 of the next storage bag 1 enters the support frame 4 under the action of the guiding rod 3. If other problems such as the storage bag 1 getting stuck or the bag tube 15 breaking occur in these steps, since the through groove 44 is located at the top of the support frame 4, it is convenient to quickly repair the device and the article storage soft bag group.

[0057] By arranging the communication groove 44 at the upper end of the support frame 4, the present invention facilitates the installation of the storage bag 1 and the guiding rod 3 in the support frame 4 and subsequent maintenance.

[0058] Embodiment Four: As Figure 7 shown, the difference between Embodiment Four and Embodiments One, Two, and Three is that the limiting structure 43 is not located at the left and right ends of the support frame 4, but at the upper end of the support frame 4.

[0059] The limiting structure 43 includes a limiting roller 431 arranged at the upper end of the support frame 4 and above the guiding rod 3. The disengaging end 32 of the guiding rod 3 has a smooth height decreasing end face 321, and the limiting roller 431 can abut against the height decreasing end face 321 when pulling the bag tube to limit the guiding rod 3 from disengaging from the support frame 4.

[0060] Specifically, the limiting roller 431 limits the upper part of the separation end 32, so that the guide rod 3 is restricted in the support frame 4 and will not protrude from the support frame outlet 42. Compared with the first to third embodiments, the contact area between the bag tube 15 and the limiting structure 43 is reduced, so that the bag tube 15 can be largely exposed at the support frame outlet 42, facilitating the bag tube 15 to protrude from the support frame outlet 42.

[0061] By providing the limiting structure 43 at the upper end of the support frame 4, the present invention reduces the contact area between the bag tube 15 and the limiting structure 43, so that the bag tube 15 can be largely exposed at the support frame outlet 42, facilitating the bag tube 15 to protrude from the support frame outlet 42.

[0062] In the present invention, the structure of the support frame 4 is not limited to the support frame 4 described in the first to fourth embodiments. Other support frames 4 that can achieve the replacement between adjacent storage bags 1 in the article storage soft bag group of the present invention are also within the protection scope of the present invention.

[0063] More embodiments: Based on the present invention, adding additional mechanisms such as a pulling mechanism for automatically pulling the storage bag 1, or a fan mechanism for completely opening the bottom of the storage bag 1, or a heating mechanism, etc., are also within the protection scope of the present invention.

[0064] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
