Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bags, in particular to a novel self-sealing bag. Background Art
[0002] The types of food bags are diversified. For example, in a common self-sealing bag, a self-sealing strip mechanism is installed at the bag opening of the bag body, that is, a concave strip and a convex strip are engaged to seal the bag opening. In some cases, items that are not suitable for children to eat are stored in the self-sealing bag. The common self-sealing strip mechanism is easy to be opened by children, which poses a safety hazard.
[0003] In response to this, a sound bone type self-sealing strip mechanism appears on the market, that is, a plurality of grooves are formed on the convex strip, and convex ends are formed on both sides of the bottom of the groove, such as a sheet body. The convex ends protrude outside the side surface of the convex strip. When tearing after the concave and convex engagement, a sound can be emitted to play a reminder role, but it cannot directly prevent the opening of the bag opening, and there is still a safety hazard, which needs to be improved. Summary of the Utility Model
[0004] To solve the above at least one technical defect, the utility model provides the following technical solutions:
[0005] This application document discloses a novel self-sealing bag, including a bag body. At least two groups of self-sealing strip mechanisms are provided at the bag opening of the bag body. The self-sealing strip mechanism at the upper part is of the sound bone type. A locking mechanism is provided at the upper bag opening of the sound bone type self-sealing strip mechanism. The locking mechanism includes a left plate body, a right plate body, a sliding plate, and a hook body. The left plate body and the right plate body are respectively fixed on both sides of the bag opening. The sliding plate is slidably connected to the right plate body along the length direction. A dial rod is provided at the position where the sliding plate protrudes from the top surface of the right plate body, and a hook body is provided on the surface facing the left plate body. An accommodating cavity is formed along the length inside the left plate body, and an L-shaped groove is provided on the plate surface facing the right plate body. The longitudinal end of the L-shaped groove allows the hook body to enter the accommodating cavity, and its transverse end enables the hook body to form a sliding fit with the left plate body.
[0006] In this solution, the structure is improved. On the basis of the conventional self-sealing strip mechanism and the sound bone type self-sealing strip mechanism, a locking mechanism is added. During use, the left and right plate bodies are close to each other, so that the hook body enters the accommodating cavity from the L-shaped groove, and the dial rod is used to slide the sliding plate, so that the hook body is misaligned with the longitudinal end groove opening of the L-shaped groove. After misalignment, the hook body is hooked to the left plate body to limit the separation of the left and right plate bodies, then the opening of the bag opening is restricted, preventing children from opening it. The sound bone type self-sealing strip mechanism will make a sound when opened, which can give a sound warning. The normal self-sealing strip mechanism mainly plays a role in sealing.
[0007] Further, a chute is provided on the right plate body along the length direction, and the sliding plate is slidably connected to the chute, forming a sliding connection between the chute and the sliding plate, which is convenient for assembly.
[0008] Furthermore, the longitudinal interface of the sliding plate is T-shaped. The top end of the sliding plate extends out of the sliding groove, and the horizontal end at the bottom of the sliding plate is located below the sliding groove. The length of the horizontal end at the bottom of the sliding plate is greater than the width of the sliding groove. The T-shaped sliding plate restricts detachment and improves stability.
[0009] Furthermore, the lever extends longitudinally, facilitating the application of force to slide the sliding plate.
[0010] Furthermore, the sliding plate, the hook body, and the lever are integrally formed, facilitating assembly and molding.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. On the basis of the normal state and the sound bone type self-sealing strip mechanism, the present utility model adds a locking mechanism. By applying force to the lever to slide the sliding plate, the hook body is displaced to hook up with the left plate body to restrict the opening of the bag mouth, avoiding children from accidentally opening the self-sealing bag and improving safety.

[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments.
[0021] Embodiment 1
[0022] As Figure 1 ,Figure 2 , Figure 3 , Figure 4 As shown, the new self-sealing bag in this example includes a bag body 1, and two sets of self-sealing strip mechanisms are arranged at the bag mouth of the bag body 1. The self-sealing strip mechanism 2 at the bottom is a common concave-convex bite type, and the self-sealing strip mechanism at the top is a bone-sounding type. The bone-sounding type self-sealing strip mechanism 3 is formed with grooves on the convex strips at intervals, and convex ends are formed at both sides of the bottom of the grooves and the convex ends protrude outside the side surfaces of the convex strips. After the concave-convex bite, a sound can be made when it is torn open, which is not elaborated here.
[0023] A locking mechanism 4 is installed at the bag opening above the rattling bone-type self-sealing strip mechanism 3. The locking mechanism 4 includes a left plate 41, a right plate 43, a slide plate 44, and a hook 46. The left plate 41 and the right plate 43 are respectively glued and fixed to the two side walls of the bag opening. The left plate 41 and the right plate 43 both extend along the width direction of the bag opening.
[0024] The right plate body 43 is slidably connected to the slide plate 44 along the length direction. For example, a through hole is longitudinally formed on the right plate body 43 and the through hole extends along the length direction, that is, a slide groove. The slide plate 44 passes through the slide groove and forms a sliding connection with clearance fit. The slide groove reserves space for the slide plate to move in the width direction of the bag opening. The slide plate 44 is integrally formed with a strip-shaped lever 45 at the end surface protruding from the top surface of the right plate body 43, and the lever extends longitudinally.
[0025] The longitudinal interface of the slide plate 44 is T-shaped, the top of the slide plate 44 extends from the slide slot and the bottom transverse end of the slide plate 44 is below the slide slot. The bottom transverse end of the slide plate is longer than the width of the slide slot. The T-shaped slide plate limits separation and improves stability.
[0026] The slide plate 44 is integrally formed with a hook body 46 on the plate surface facing the left plate body 41, such as a common L-shape. An accommodating cavity is formed in the left plate body 41 along the length direction, and an L-shaped groove 47 is formed on the plate surface of the left plate body 41 facing the right plate body 43. The longitudinal end of the L-shaped groove 47 allows the hook body 46 to enter the accommodating cavity and its transverse end extends along the length direction of the left plate body 41. The hook body and the left plate body form a sliding fit through the transverse end of the L-shaped groove 47.
[0027] When in use, if the force lever is used to slide the skateboard until it cannot move, and the left and right boards are approached toward each other, the hook body on the skateboard enters the accommodating cavity from the longitudinal end notch of the L-shaped groove, and the force lever is used to slide the skateboard in the opposite direction to dislocate the hook body from the longitudinal end notch of the L-shaped groove, the hook body is hooked with the cavity wall of the left board, and the separation of the left and right boards is restricted. Children cannot separate the left and right boards, and the bag mouth cannot be opened, which helps to improve safety.
[0028] Even if a child separates the left and right panels, the sound-bone-shaped self-sealing strip mechanism will make a sound when the bag is opened, which can further serve as a reminder.
[0029] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
