Description

Detailed Description of the Invention

[0001] [Technical field] The present invention relates to a clip used to seal the opening of a bag, and more particularly to a clip designed to tightly seal the entire opening of a bag with a simple operation to prevent the contents of the bag from spilling out.

[0002] [Background technology] Generally, when a product is sealed using a plastic bag, there is a risk that air will get inside after opening, which will change the state of the contents, and that insects or dust will get inside the bag and spoil or contaminate the contents, so users usually tighten the opening with a rubber band or a tie string to seal it as much as possible to prevent air from getting in. However, this conventional sealing method has the problem of being very cumbersome to use, and so tools that can seal the opening of a bag have been invented on the market.

[0003] For example, Patent Document 1 is an invention relating to a pack sealing device, which is a tool for sealing the opening of a pack (such as bags and envelopes of various materials, sizes and shapes) containing various substances or objects including liquids, gases and solids, by folding the opening and then pushing the sealing device into the folded part.

[0004] However, this type of sealing tool has the disadvantage that the opening on one side is designed to have a predetermined gap, making it difficult to insert the pack into the opening when the pack to be sealed is relatively thick (such as a bag of rice or pet food).In addition, it is designed to require the opening at the top of the bag to be folded over once in order to seal it, which has been found to be somewhat cumbersome to use. [Prior art document] [Patent documents] [Patent Document 1] Korean Patent No. 10-0416405 [Summary of the Invention] [Problem to be solved by the invention] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a clip that can seal the opening of a bag with a simple operation.

[0005] Another object is to provide a sealing clip that is compatible with a wide range of bags, even those with large sizes or thicker thicknesses. [Means for solving the problem] According to one embodiment of the present invention, a clip for sealing an opening of a bag includes a base extending longitudinally and having fastening pins formed at both ends thereof, a handle portion disposed above the base and extending longitudinally, and a movable frame including a resilient member disposed at both ends of the handle portion, one end of which is connected to the fastening pin and the other end of which is constrained by the handle portion. The handle portion further includes an inner receiving portion extending longitudinally, and the resilient member is slidable along the inner receiving portion, being inserted into the inner receiving portion to a predetermined position and being pulled out to a predetermined position outside the inner receiving portion. The movable frame resiliently deforms in shape in response to an external force and moves toward or away from the base, maintaining its position at a minimum height when it is closest to the base, a maximum height when it is farthest from the base, and an intermediate height between the minimum and maximum heights.

[0006] In addition, a stopper is formed between one end and the other end of the resilient member, and the resilient member is divided into an outer portion between the one end and the stopper and an inner portion between the stopper and the other end. The inner portion is inserted into the inner accommodating portion, and the stopper is attached to the outer end of the inner accommodating portion, so that the inner portion can be inserted into the inner accommodating portion up to a predetermined position.

[0007] In addition, a pair of hook protrusions protrude from the bottom surface of the handle in the inner storage section of the handle, and a closed ring member is provided at the other end of the spring member, and each of the spring members at both ends of the handle can be assembled to the handle so that one hook protrusion is stored in the ring member.

[0008] Furthermore, the inner part of the resilient member is pulled out from the inner accommodating part, but the ring member is caught and constrained by the protrusion, so that the resilient member can be pulled out to a predetermined position outside the inner accommodating part.

[0009] In addition, the minimum height may be a state in which the two elastic members of the moving frame are fully inserted into the inner accommodating portion, causing the moving frame to have its shortest length, but is elastically bent downward and overlapping the base; the intermediate height may be a state in which the moving frame maintains its shortest length but is elastically bent upward and separated from the base by an intermediate height; and the maximum height may be a state in which the two elastic members of the moving frame are fully pulled out from the inner accommodating portion, causing the moving frame to have its longest length, but is further bent upward and separated from the base by the maximum height.

[0010] Additionally, the moving frame may be configured in stages between a minimum height, an intermediate height, and a maximum height. In addition, when the handle portion of the movable frame is pulled upward from the base at the minimum height, the movable frame elastically bulges upward while maintaining its minimum length, thereby deforming to an intermediate height; when the handle portion is pulled upward further at the intermediate height, the inner portion is pulled out from the inner storage portion, extending the length of the movable frame, and the movable frame bulges upward further, thereby deforming to the maximum height.

[0011] In addition, when the handle portion of the movable frame is pushed downward toward the base at the maximum height, the inner portion is inserted into the inner storage portion and the movable frame approaches the base, and when the movable frame reaches its shortest length, it becomes the intermediate height.When the handle portion is pushed downward further at the intermediate height, the movable frame may be deformed to elastically bulge downward while maintaining its shortest length, and may become the minimum height.

[0012] Furthermore, when the moving frame is at the lowest height, the handle portion and the base are in surface contact with each other, and a gap may be present between the pair of resilient members and the base. [Effects of the invention] According to one embodiment of the present invention, an easy-to-use sealing clip is provided that can easily seal and open the opening of a bag with a simple operation.

Below, a clip 100 used to seal the opening of a bag according to one embodiment of the present invention will be described with reference to these drawings.

[0019] The clip 100 of the present invention includes a base 110 and a moving frame 130 . Referring to the drawings, the base 110 extends longitudinally and has fastening pins 111 formed at both ends thereof. The base 110, together with the movable frame 130 as described below, pressurizes and seals the side of the opening of a bag inserted therebetween. The side shape of the base 110 may be configured, for example, as shown in FIG. 1 or 2, with a flat central region and curved upward toward both ends. Fastening pins 111 are formed at both ends of the base 110, and a resilient member 150 of the movable frame 130, described below, is pivotally coupled thereto. For example, as shown in FIG. 1, an L-shaped post with an inwardly curved upper end may be formed at each end of the base 110, and a fastening pin 111 may be formed in each post. A fastening hole is formed at one end of the resilient member 150, and the fastening pin 111 of the base 110 may be inserted into the fastening hole to couple the two together. The base 110 may be formed as a single unit, or alternatively, may be formed by two left and right pieces fixedly joined at the center. Alternatively, a slit may be formed in the center of the width of the base 110, and a reinforcing plate made of a rigid material may be inserted into the slit to provide rigidity to the base 110. At least one raised portion 123 is disposed along the length of the upper surface of the base 110. For example, as shown in FIG. 1, two raised portions 123 may be arranged along the length of the base 110. The raised portion 123 is disposed to face a groove 152 recessed in the lower surface of an outer portion 153 of a resilient member 150 (described later), thereby more firmly fixing a bag therebetween when the base 110 and the moving frame 130 are positioned adjacent to each other.

[0020] Meanwhile, the moving frame 130 includes a handle 140 disposed above the base 110 and extending in the longitudinal direction, and a pair of resilient members 150 disposed at both ends of the handle 140, one end of which is connected to a fastening pin 111 by a screw or other means and the other end of which is constrained to the handle 140. The resilient members 150 can bend to correspond to the shape of the surface of the base 110 when the base 110 and the moving frame 130 are at their lowest height (see FIG. 6a), or can bend upward when the base 110 and the moving frame 130 are at their intermediate or highest heights (see FIGS. 6b and 6c). The bending deformation of the resilient members 150 can flexibly deform the shape of the entire moving frame 130. That is, at its highest height, the moving frame 130 bends upward as shown in FIG. 6c, and at its lowest height, its shape resiliently deforms to bulge downward, approaching the base 110 as shown in FIG. 6a. For this purpose, the resilient member 150 may be made of, for example, POM (polyacetal) material. POM has excellent elastic recovery and fatigue resistance, so it can maintain a long life even when subjected to repeated deformations. Meanwhile, a handle is provided at the center of the handle 140 so that the user can grasp it with their fingers, and a hole for fixing a handle loop may be optionally provided for easier gripping. The handle 140 may be coupled to the base 110 via the resilient members 150 provided at both ends.

[0021] Here, as shown in Fig. 3d, a groove 152 may be formed on the lower surface of the outer part 153 of the resilient member 150. The groove 152 is configured to receive the raised part 123 formed on the upper surface of the base 110 inside. Such a groove 152 may be formed by forming a groove on the lower surface of the resilient member 150 through a separate process, for example, as shown in Fig. 3d, it may be formed by forming the cross section of the resilient member 150 into a U-shape. As a result, when the base 110 and the movable frame 130 approach each other, the bag inserted therebetween is restrained by the raised part 123 and the groove 152, and therefore does not slip out of the base 110 and the movable frame 130.

[0022] The handle 140 further includes an inner accommodating portion 141 extending lengthwise. As shown in FIG. 3e, the inner accommodating portion 141 is a hollow, hexahedral conduit with a rectangular cross section provided inside the handle. The inner accommodating portion 141 slidably accommodates the inner portion 155 of the resilient member 150 therein. The left resilient member 150 is inserted / pulled out through the inner accommodating portion 141 that is open on one side of the handle 140 in the lengthwise direction (the left side in FIG. 3e), and the right resilient member 150 is inserted / pulled out through the inner accommodating portion 141 that is open on the other side of the handle 140 in the lengthwise direction (the right side in FIG. 3e). Therefore, the cross-sectional size of the inner accommodating portion 141 is larger than the cross-sectional size of the inner portion 155 of the resilient member 150.

[0023] Meanwhile, one end of one of the resilient members 150 is pivotally connected to the left fastening pin 111, and one end of the other resilient member 150 is pivotally fixed to the right fastening pin 111. In this way, one end of each resilient member 150 is constrained by the fastening pins 111 on both sides, and the other end of each resilient member 150 is slidable along an inner receiving portion 141 provided in the handle portion 140. The resilient member 150 is divided into an outer portion 153 between one end and the stopper 151 and an inner portion 155 between the stopper 151 and the other end (see FIG. 1 ). The portion of the resilient member 150 that slides along the inner receiving portion 141 is the inner portion 155 of the resilient member 150, and the entire length of the movable frame 130 extending from the handle portion 140 to the resilient members 150 on both sides is adjusted by the inner portion 155 sliding inward and outward along the inner receiving portion 141. At this time, the spring member 150 has a stopper 151 (Fig. 3d) formed between one end and the other end, protruding upward or to the side, and the inner portion 155 is inserted into the inner accommodating portion 141, and the stopper 151 is engaged with the outer end of the inner accommodating portion 141, so that the inner portion 155 can be inserted into the inner accommodating portion 141 up to a predetermined position.

[0024] Meanwhile, a pair of barb protrusions 156 (FIG. 3e) protrude from the bottom surface of the inner accommodating portion 141 of the handle portion 140. A closed ring member 157 is provided at the other end of the resilient member 150. Each of the resilient members 150 provided at both ends of the handle portion 140 is assembled to the handle portion 140 so that one barb protrusion 156 is housed in the corresponding ring member 157. In other words, since the barb protrusions 156 are present in the inner region of the ring member 157, when the resilient member 150 is pulled outward from the inner accommodating portion 141, the ring member 157 is pulled out until it engages with the barb protrusions 156. As a result, the ring member 157 is restrained by the barb protrusions 156, and the resilient member 150 is pulled outward from the inner accommodating portion 141 to a predetermined position.

[0025] The movable frame 130 according to the present invention is elastically deformed by an external force and moves toward or away from the base 110, but maintains its position at a minimum height where it is closest to the base 110, a maximum height where it is farthest from the base 110, or an intermediate height between the minimum and maximum heights. The minimum height is shown in Figure 6a, the intermediate height in Figure 6b, and the maximum height in Figure 6c.

[0026] The minimum height in Figure 6a is the state in which the two resilient members 150 of the moving frame 130 are fully inserted into the inner receiving portion, causing the moving frame 130 to be at the shortest distance, but is resiliently bent downward and overlapping the base 110. The shortest distance state is shown in Figure 5b, where the stopper 151 of the resilient member 150 rests on the outer end of the handle, and the inner portion 155 is inserted deepest into the inner receiving portion 141. In this state, the overall length of the moving frame 130 is at its shortest, and the moving frame 130 is maintained in a resiliently bent downward state.

[0027] At the intermediate height in Figure 6b, the moving frame 130 maintains its minimum length but is elastically bent upward and spaced an intermediate distance from the base 110. The length of the moving frame 130 is the same as at the minimum height in Figure 6a, where the inner part 155 is inserted deepest into the inner receiving part 141, but the outer shape of the moving frame 130 is deformed to be curved upward. For example, when the moving frame 130 is at its minimum height, if the user pulls the handle 140 upward, the downwardly bulging moving frame 130 elastically bounces and deforms to be elastically bent upward.

[0028] 6c is a state in which the two resilient members 150 of the moving frame 130 are fully extended from the inner receiving portions 141, causing the moving frame 130 to be at its longest length, but is further curved upward and spaced apart from the base 110 by the maximum height. For example, when the moving frame 130 is at an intermediate height, if the user further pulls the handle 140 upward, the resilient members 150 are extended from the inner receiving portions 141, increasing the overall length of the moving frame 130, and in the process, the moving frame 130 is further curved upward. In this case, the inner portions 155 of the resilient members 150 are engaged and connected to the inner receiving portions 141 of the handle 140, and the above-mentioned height deformation can occur when the handle 140 is pulled upward with a force stronger than the frictional force between the inner portions 155 and the inner receiving portions 141.

[0029] In this manner, the moving frame 130 is selectively configured between a minimum height, an intermediate height, and a maximum height, and more particularly, is configured in a stepwise fashion therebetween. The position and shape changes of the moving frame 130 will be described in detail below with reference to FIGS. 6a to 6c.

[0030] As described above, the handle unit 140 is provided with a handle, and the user pulls the handle upward with their fingers or pulls upward a handle loop (not shown) additionally provided on the handle unit 140 to unfold the moving frame 130 from the base 110. With the base 110 and the moving frame 130 unfolded, a bag to be sealed is placed between them, and the moving frame 130 is pressed toward the base 110, thereby sealing the open opening of the bag using the firm compressive force between the two members. This operation can be achieved by elastically changing the relative position of the moving frame 130 with respect to the base 110.

[0031] First, at the lowest height in FIG. 6a, the inner portion 155 of the resilient member 150 is disposed in the inner receiving portion 141, and the moving frame 130 overlaps the base 110. Referring to FIG. 2, when the moving frame 130 is at its shortest length, the linear width between both ends is longer than the linear width between both ends of the base 110. Therefore, when the moving frame 130 is assembled to the base 110, the width of the base 110 becomes narrower, and the moving frame 130 is bent upward or downward. When the moving frame 130 is pressed downward, the moving frame 130 resiliently bends and overlaps the base 110. The handle portion 140 at the center of the moving frame 130 and the base 110 are in surface contact, and a gap may be provided between the resilient member 150 on the side of the moving frame 130 and the base 110. To this end, for example, the height of both longitudinal sides of the base 110 may be designed to be lower than the height of the center of the longitudinal direction.

[0032] When the handle 140 of the moving frame 130 is pulled upward from the base 110 at its minimum height, the moving frame 130 resiliently expands upward while maintaining its minimum length, reaching an intermediate height. Specifically, as the user pulls the handle upward, the moving frame 130 gradually lifts from the base 110, and the resilient member 150 continuously presses the handle 140. Next, at the moment the handle 140 separates from the base 110 by a critical distance, the resilient member 150 resiliently bounces off the handle 140, instantly transforming from its downward curve to an upwardly expanded shape. This causes the moving frame 130 to bend upward, as shown in FIG. 6b, creating a space between the moving frame 130 and the base 110. In this state, the moving frame 130 maintains its minimum length.

[0033] On the other hand, when the handle 140 is pulled further upward from the intermediate height, the inner part 155 is pulled out of the inner receiving part 141, extending the length of the movable frame 130, and the movable frame 130 is deformed to bulge further upward, reaching its maximum height. More specifically, when the user pulls the handle further upward, if the force is greater than the frictional force between the inner part 155 and the inner receiving part 141, the inner part 155 begins to slide outward out of the inner receiving part 141. As this sliding continues, the ring member 157 of the inner part 155 engages with the protrusion, stopping the sliding and the movable frame 130 reaching its maximum length. During this process, the movable frame 130 is bent upward and separated from the base 110 by its maximum height. Even as the length of the moving frame 130 increases, the inner part 155 of the elastic member 140 continuously presses the inner wall of the inner accommodating part 141 outward. Therefore, when the external force of the user becomes smaller than the frictional force as the moving frame 130 reaches its maximum height, the moving frame 130 can maintain its state at that moment.

[0034] 6b and 6c, the moving frame 130 maintains its upwardly expanded state, and at this time, the post provided on the base 110 has an L-shaped protrusion at its upper end that is bent inward, so that the protrusion comes into contact with the elastic member 150 of the moving frame 130. As a result, the protrusion restricts the upward movement of the moving frame 130, thereby guiding the moving frame 130 to prevent it from shaking.

[0035] At the intermediate or maximum height, the user places the opening of a bag between the base 110 and the moving frame 130 and presses the handle 140 toward the base 110 to seal the opening of the bag, moving the moving frame 130 toward the base 110. When the moving frame 130 is brought closer to the base 110 at the maximum height, the resilient members 150 on both sides press against the handle 140 between them. If the pressure is greater than the frictional force, the inner part 155 enters the inner receiving part 141, reducing the length of the moving frame 130 and lowering its height from the base 110. During this process, the stopper 151 engages the outer end of the handle 140, shortening its length and positioning the moving frame 130 at the intermediate height (FIG. 6b). When the moving frame 130 is brought even closer to the base 110 at the intermediate height, the resilient members 150 on both sides of the handle 140 are pressed, building up elasticity. As this pressure continues, one or both of the resilient members 150 are resiliently deformed into a downwardly bulging shape, and the handle 140 and the pair of resilient members 150 overlap the upper surface of the base 110 (see FIG. 6a).

[0036] The clip of the present invention can be set to the intermediate height described above, with the opening of the bag positioned in the space between the movable frame 130 and the base 110, and then the clip can be deformed to its minimum height to close the bag's opening. However, a cup used to dispense the contents (e.g., feed) is often placed inside the bag. The user opens the clip to the intermediate height while it is closing the bag's opening, releases the bag, and then removes the cup from the bag to scoop the contents. However, if the cup is large and the space between the movable frame 130 and the base 110 at the intermediate height is smaller than the cup, the cup may not be able to enter or exit this space. In this case, the user would have to detach the entire clip from the bag to scoop the feed and then reinsert the clip into the bag after use, which would be inconvenient. Therefore, the present invention is designed to allow the clip to be set to its maximum height, which is higher than the intermediate height. At the maximum height, the space between the moving frame 130 and the base 110 is large, so that the cup can be taken out of or placed in the bag with the bag open and the clip hanging around the opening of the bag, so that it is not necessary to separate the clip from the opening of the bag in order to take out and use the cup.

[0037] Furthermore, when transforming from the intermediate height state of FIG. 6b to the lowest height state of FIG. 6a, only one of the left and right resilient members 150 may be resiliently deformed downward. Referring to FIG. 6d, when moving frame 130 is pressed downward in the intermediate height state of FIG. 6b, only the left resilient member 150 is deformed to bulge downward and overlap base 110, while the right resilient member 150 remains bulged upward. When pressure is applied at a position slightly deviated from the center of handle 140, only one resilient member 150 is deformed as described above. With this configuration, the space between moving frame 130 and base 110 into which the opening of the bag is inserted is narrower than in the intermediate height state of FIG. 6b. Therefore, when opening and closing base 110 and moving frame 130, if the bag size is small, one resilient member 150 can remain overlapping base 110, and only the remaining resilient member 150 can be deformed, allowing the bag clip of the present invention to be adapted to the size of the bag.

[0038] The above description is merely one embodiment for implementing the clip used to seal the opening of a bag according to the present invention, and the present invention is not limited to the above embodiment. It should be noted that the technical concept of the present invention is within the scope of the following claims, and anyone having ordinary skill in the art to which the present invention pertains can make various modifications without departing from the gist of the present invention.
