Description

Technical Field

[0001] The present application relates to the technical field of packaging, and particularly to a press-to-open lid structure and a package body. Background Art

[0002] In the prior art, contents such as wet wipes, cotton soft towels, paper towels, etc. are usually housed in a packaging box or a packaging bag. An extraction opening is provided on the packaging box or the packaging bag, and the contents are drawn out from the extraction opening. A lid is provided on the packaging box or the packaging bag, and the lid can seal the extraction opening to prevent the contents from losing water or getting soiled.

[0003] In the related art, there are three ways to open the lid as follows: 1. The box lid and the base are fixed by a buckle. When opening, generally one hand needs to press the wet wipes and the other hand opens the box lid. This method is relatively complicated to operate and is not convenient for single-handed operation. 2. By adding a spring piece at the connection, when pressing, the lid is opened by the resilience of the spring piece, and the purpose of the spring lid can be achieved. In this method, the spring piece and the lid are made of different materials and need to be manually installed additionally, with low efficiency and high cost. 3. By providing a lever member on the base, the lid is opened by pressing the lever member. In this method, the lever member is likely to open the lid when accidentally touched.

[0004] It can be seen that all three ways to open the lid have certain defects, so there is an urgent need for a lid structure with a new way to open the lid. Utility Model Content

[0005] Based on this, it is necessary to provide a press-to-open lid structure and a package body that are convenient for single-handed operation and not easily opened by mistake.

[0006] A press-to-open lid structure is used on a package body. The package body is used to house contents and is provided with an extraction opening. The press-to-open lid structure is installed at the extraction opening. The press-to-open lid structure includes:

[0007] A seat body is installed at the extraction opening. A first through hole is provided on the seat body, and the first through hole is used to correspond to the extraction opening.

[0008] A lid body is hinged to the seat body. The lid body has a closed state and an open state. When the lid body is in the closed state, it covers the through hole.

[0009] A lever member has a first end, a second end and a fulcrum. The fulcrum is rotatably connected to the seat body. When a force is applied to the first end, the lever member pivots about the fulcrum as a pivot axis, and the second end moves the lid body from the closed state to the open state.

[0010] Wherein, the first end is installed in the seat body, and in the height direction of the seat body, the top surface height of the first end is lower than / equal to the top surface height of the seat body.

[0011] In one embodiment, the lever member is completely received in the seat body, and a second through hole corresponding to the extraction port is provided on the lever member.

[0012] In one embodiment, when the cover body is in a closed state, the second end portion is located between the cover body and the seat body; the first end portion is exposed from the cover body, and in the height direction, there is a gap between the bottom surface of the first end portion and the seat body.

[0013] In one embodiment, the lever member, the first end portion, the second end portion, and the fulcrum are of an integrally formed structure.

[0014] In one embodiment, a flange is provided on one side of the first end portion close to the cover body, and when the cover body is in a closed state, the flange is in abutting cooperation with the cover body.

[0015] In one embodiment, a recess is provided on the seat body, and the recess is provided on one side of the seat body corresponding to the first end portion.

[0016] In one embodiment, the lever member has a length direction and a width direction, and the fulcrums are provided at both ends in the length direction of the lever member; convex shafts corresponding to the fulcrums are provided on the seat body, and the convex shafts are rotatably inserted into the fulcrums.

[0017] In one embodiment, the pressing and opening cover structure further includes a locking member for locking and positioning the cover body in a closed state.

[0018] In one embodiment, two sets of the locking members are provided, and the two sets of the locking members are symmetrically provided on both sides of the cover body.

[0019] In one embodiment, the locking member includes a clamping portion and a clamping groove, the clamping portion is provided on the cover body, and the clamping groove is provided on the seat body; when the cover body is in a closed state, the clamping portion is in clamping cooperation with the clamping groove.

[0020] The present application also provides a packaging body, including a bag body and the pressing and opening cover structure as described in any one of the above embodiments. The bag body is provided with the extraction port, and the pressing and opening cover structure is located at the extraction port and is installed on the bag body.

[0021] Compared with the prior art, the pressing and opening cover structure has the following technical effects:

[0022] 1. The cover body is opened by pivoting the lever member, and the cover body can be turned over with one hand to expose the extraction port. One-handed operation for opening the cover is realized, which is simple and fast.

[0023] 2. The lever member can be injection-molded from plastic, which is more convenient to process and has a lower cost compared to installing a spring.

[0024] 3. By setting the top surface height of the second end to be lower than or equal to the top surface height of the base, the top surface of the second end will not protrude from the top surface of the base. Thus, when an external object or external force accidentally touches the cover structure, the force will act on the seat body rather than the second end, and thus will not press the second end to open the cover, avoiding accidental opening.

The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.

[0038] Please refer to Figures 1 to 6, the present application provides a package for accommodating the content 10. The package includes a bag body 30 and a pressing-open lid structure 40. The bag body 30 is provided with a drawing opening 20, and the pressing-open lid structure 40 is located at the drawing opening 20 and is installed on the bag body 30.

[0039] Refer to Figures 2 to 6 , the pressing-open lid structure 40 includes a seat body 41, a lid body 42, and a lever member 43. Among them, the seat body 41 is installed at the drawing opening 20. And a first through hole 411 is provided on the seat body 41, and the first through hole 411 is used to correspond to the drawing opening 20. The lid body 42 is hinged to the seat body 41, that is, the lid body 42 can flip up and down relative to the seat body 41 around the hinge. The lid body 42 has a closed state and an open state. When the lid body 42 is in the closed state, it covers the first through hole 411. The lever member 43 has a first end 431, a second end 432, and a fulcrum 433. The fulcrum 433 is rotatably connected to the seat body 41. When a force is applied to the first end 431, the lever member 43 pivots about the fulcrum 433 as the pivot axis, and the second end 432 moves the lid body 42 from the closed state to the open state.

[0040] Among them, the first end 431 is installed inside the seat body 41, and in the height direction of the seat body 41, the top surface height of the first end 431 is lower than / equal to the top surface height of the seat body 41.

[0041] It can be understood that in this structural setting, the top surface of the second end 432 will not protrude from the top surface of the base. Even if an external object or external force accidentally touches the lid structure, the acting force of the accidental touch will act on the seat body 41 rather than the second end 432, and thus the second end 432 will not be pressed to open the lid body 42, avoiding the situation of accidental opening.

[0042] Understandably, the above-mentioned closed state means that the lid body 42 is completely received inside the seat body 41 or completely covers the seat body 41. In this embodiment, it is preferably set to the state of being completely received inside the seat body 41, which is more beautiful in appearance.

[0043] The above-mentioned open state refers to the remaining states in which the lid body 42 and the seat body 41 are separated from the closed state, such as there is a certain gap between the two, or the lid body 42 is turned up to expose part of the first through hole 411, or the lid body 42 is turned over completely to expose the first through hole 411. These states can all be defined as the open state.

[0044] See Figure 2 , the shape of the seat body 41 is in a pattern similar to a cloud, and the seat body 41 is integrally hollowed out. The above-mentioned pattern similar to a cloud is composed of 1-5 circles with a diameter of 2 cm - 7 cm. The specific quantity and size can be selected according to the actual situation.

[0045] Further, the length of the seat body 41 is set to 6 - 12 cm, and the width is set to 3.5 - 7 cm. Specific dimensions can be selected according to the actual situation.

[0046] Further, the first through hole 411 is opened at the position of the seat body 41 corresponding to the extraction port 20, and the shape of the first through hole 411 is set as an irregular hole.

[0047] Further, the lever member 43 is completely received within the seat body 41. The lever member 43 is provided with a second through hole 44 corresponding to the extraction port 20. Thus, the existence of the lever member 43 is not visible from the outside, making the overall appearance more aesthetically pleasing. The setting of the second through hole 44 ensures that the existence of the lever member 43 does not block the extraction port 20, guaranteeing the smooth extraction of the content 10.

[0048] In an embodiment, when the cover body 42 is in a closed state, the second end portion 432 is located between the cover body 42 and the seat body 41. The first end portion 431 is exposed outside the cover body 42, and in the height direction, there is a gap 45 between the bottom surface of the first end portion 431 and the seat body 41.

[0049] Understandably, the exposure of the first end portion 431 facilitates the alignment for pressing. The existence of the gap 45 ensures that there is sufficient space for the first end portion 431 to move downward when it is pressed down, thereby enabling the lever member 43 to pivot by a sufficient angle, and ultimately ensuring that the second end portion 432 can move upward by a sufficient distance to push open the cover body 42.

[0050] Secondly, the second end portion 432 is located between the cover body 42 and the seat body 41, enabling the second end portion 432 to fully abut against the cover body 42 when it moves upward, and thus making it easier to open the cover body 42.

[0051] In this embodiment, the pivoting angle of the lever member 43 is preferably set to be less than 15°. The larger the set angle, the larger the size of the gap 45 needs to be, that is, the higher the height of the base needs to be set. A too high base not only increases the cost but also is not aesthetically pleasing in appearance. Setting a pivoting angle within 15° can already meet the requirement of prying the cover body 42 and satisfy normal use.

[0052] Preferably, the bottom surface of the second end portion 432 is provided with an inclined surface 432a that slopes downward from top to bottom. Without changing the height of the base, the size of the gap 45 is further increased.

[0053] Furthermore, the lever member 43 can be formed by splicing multiple parts, or it can be integrally formed. In this embodiment, an integrally formed structure is preferably adopted to simplify the processing steps.

[0054] Specifically, the lever member 43 has a length direction Y and a width direction X. The fulcrums 433 are provided at both ends of the lever member 43 in the length direction Y. The first end portion 431 and the second end portion 432 are provided at both ends in the width direction X. The fulcrum 433 is located between the first end portion 431 and the second end portion 432 and is close to the central position of the distance between the two.

[0055] It can be understood that the integrally formed structure mentioned above, that is, the lever member 43, the fulcrum 433, the first end portion 431, and the second end portion 432 are all integrally processed. The integrally processing method can be injection molding, cutting, etc. In this embodiment, the lever member 43 is made of plastic and is preferably integrally formed by injection molding.

[0056] Preferably, the outer shape of the lever member 43 fits the shape of the hollow inside the seat body 41. The first end portion 431 has a certain width, and the second end portion 432 is provided as an irregular rod. Both ends of the second end portion 432 are connected to the first end portion 431, and the empty part in the middle after enclosing is the above-mentioned second through hole 44.

[0057] Preferably, the shape of the cover body 42 is also set as an irregular structure. When the cover body 42 is closed, the shape formed by the cover body 42 and the first end portion 431 is preferably the shape of the base, and it is similar to the cloud-like structure of the base in appearance. It forms a cover surface with a length of 6 - 12 cm and a width of 3.5 cm - 7 cm. The specific size of the cover surface can be selected according to the actual situation.

[0058] In this embodiment, the fulcrum 433 is set as a groove on the lever member 43 and extends along the length direction of the lever member 43. A convex shaft 46 is provided on the seat body 41 at the position corresponding to the fulcrum 433. The convex shaft 46 is partially inserted into the fulcrum 433 and can rotate relative to the fulcrum 433.

[0059] Of course, it is not limited to this. In other embodiments, the fulcrum 433 can also be set as a protrusion, and a groove is provided on the seat body 41, and the two can be rotatably inserted.

[0060] Exemplarily, a flange 431a is provided on one side of the first end portion 431 close to the cover body 42. When the cover body 42 is in the closed state, the flange 431a abuts and cooperates with the cover body 42. In this structure, when the cover body 42 is closed, the flange 431a is just located at the gap between the cover body 42 and the first end portion 431, thereby blocking the gap between the two and improving the sealing effect of the structure to prevent the content 10 from losing water.

[0061] Preferably, the flange 431a covers the entire first end portion 431 to ensure the integrity of the cover surface formed by the first end portion 431 and the cover body 42.

[0062] Further, a concave portion 412 is provided on the seat body 41, and the concave portion 412 is provided on one side of the seat body 41 corresponding to the first end portion 431. Preferably, it is provided at a position corresponding to the middle of the first end portion 431. During the process of pressing the first end portion 431 downward with a finger, the presence of the concave portion 412 provides a certain amount of clearance for the finger, avoiding contact between the seat body 41 and the finger, and making the pressing operation more comfortable.

[0063] Exemplarily, the concave portion 412 can be set as an arc-shaped structure, and the transition between the concave portion 412 and the base can also be set as a continuous arc surface, making it softer when in contact with a finger.

[0064] See Figure 2 、 Figure 3 In addition, the pressing and opening cover structure 40 further includes a locking member 50 for locking and positioning the cover body 42 in a closed state.

[0065] Preferably, two sets of locking members 50 are provided, and the two sets of locking members 50 are symmetrically provided on both sides of the cover body 42. The cover body 42 is firmly locked by the two sets of locking members 50, ensuring that the cover body 42 will not be accidentally opened during transportation, and avoiding the situation where the cover body 42 is damaged due to accidental opening and collision.

[0066] Further, each set of locking members 50 includes a clamping portion 51 and a clamping groove 52. Among them, the clamping portion 51 is provided on the cover body 42, and the clamping groove 52 is provided on the seat body 41. When the cover body 42 is in a closed state, the clamping portion 51 is engaged with the clamping groove 52 to realize the position limitation of the cover body 42.

[0067] Of course, it is not limited to this. In other embodiments, the clamping portion 51 can also be provided on the seat body 41, and the clamping groove 52 can be provided on the cover body 42. As long as the position limitation and locking of the cover body 42 are satisfied.

[0068] In this embodiment, the content 10 refers to wet wipes, paper towels, etc., which are generally made of a single layer or multiple layers of materials such as opp, pet, and pe, and the quantity is set to be 10 - 100 sheets. The size of the extraction opening 20 is set to 40 * 20 mm, and the specific value can be selected according to actual needs.

[0069] Of course, a sealing sticker 60 can also be provided on the bag body 30, and the sealing sticker 60 is adhered to the bag body 30 by an adhesive. The size of the sealing sticker 60 is set to be larger than the size of the extraction opening 20, so that when it is adhered to the bag body 30, it can close the extraction opening 20. When the sealing sticker 60 is torn or removed, the extraction opening 20 can be opened.

[0070] Preferably, the size of the sealing sticker 60 is set to be more than 7 mm larger than the extraction opening 20, and the specific value can be selected according to actual needs.

[0071] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0072] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
