Implementation mode one

The first embodiment of the present invention provides a sealed container and a sealed locking snap-fit lid, as shown in fig. 1, the sealed locking snap-fit lid comprises a sealed locking snap-fit lid 10 and a container body 20, which are used cooperatively, an opening edge 21 is provided on the outer side wall at the opening end of the container body 20, and the container body 20 is clamped and fixed with the lid 10 by the opening edge 21. The container body 20 is used for storing articles therein, and the sealing and locking snap-fit lid 10 (hereinafter, also referred to as the lid 10) is used for sealing the opening of the container body 20, thereby playing a role in water and dust prevention. The sealed container with high sealing performance also has the functions of preventing leakage and preventing burglary.

As shown in fig. 1 and 2, the snap-fit lid 10 includes a lid body 1 and a lid rim 2 protruding from an edge of the lid body 1, wherein the lid rim 2 and the lid body 1 are formed in a groove shape with one side opened so as to cover the opening of the container body 20 when being engaged with the container body 20. The lid rim 2 may be provided along the edge of the lid body 1 in a full-covering manner as in the present embodiment, or may be provided partially along the edge of the lid body 1, as long as it can seal the opening of the container body 20 with the container body 20.

In particular, in the present embodiment, the sealing and locking snap-fit lid 10 further includes a locking snap 3, the locking snap 3 is detachably disposed on the lid rim 2, and when the lid 10 is covered on the periphery of the container body 20, the locking snap 3 is used to lock the lid rim 2 with the container body 20 to form a locking structure. Thus, the cover 10 and the container body 20 are not easy to be opened, and once the cover 10 is opened, the deformation or the breakage of the cover is inevitably caused, so that the user is reminded that the sealed container is opened by others, and the sealing performance and the anti-theft performance of the sealed container are improved.

Specifically, as shown in fig. 2 and 3, the locking buckle 3 includes a buckle body 3a, an insertion portion 3b and a buckling portion 3c, and the cover edge 2 is provided with an insertion port 2a adapted to the insertion portion 3 b. The insertion part 3b is disposed at one end of the buckle body 3a, and when the buckle body is connected with the cover rim 2 in an assembling manner, the insertion part 3b extends into the cover body 10 through the insertion port 2a, and when the cover body 10 covers the container body 20, the insertion part 3b extends into the lower part of the opening edge 21 of the container body 20. More preferably, the socket 3b abuts on an outer wall of the container body 20. The lower side of the opening edge 21 of the container body 20 means that the orthographic projection of the opening edge 21 partially coincides with the insertion part 3b in the direction in which the container body 20 is perpendicular to the plane of the lid body 10. When the locking buckle 3 moves towards the opening direction of the container body 20, the opening edge 21 will intercept the plug part 3b, and further movement of the plug part 3b is prevented.

The buckling parts 3c are arranged at the positions of the buckling body 3a far away from the insertion part 3b, preferably at two sides of the middle part of the buckling body 3a, so that when the locking buckle 3 is connected with the cover edge 2 in an assembling way, the buckling parts 3c extend into the cover edge 2 from the insertion opening 2a and are abutted against the inner wall of the cover edge 2. The rounded corner 3c1 is provided on the side of the fastening portion 3c facing the insertion portion 3b, and when the locking clip 3 is mounted, the rounded corner 3c1 facilitates the fastening portion 3c to pass through the insertion opening 2 a. The outer diameter of the buckling part 3c is larger than the inner diameter of the insertion opening 2a, and here, the width of the locking buckle 3 including the buckling part 3c is larger than the width of the insertion opening 2 a. The fastening of the locking buckle 3 and the cover rim 2 is realized by the arrangement of the fastening part 3c, and the locking buckle 3 which is installed on the cover rim 2 is prevented from falling off from the outer part of the cover rim 2.

Compared with the prior art, the assembled cover body 10 with the sealing and locking buckle provided by the embodiment has the advantages that by arranging the locking buckle 3, when the cover body 10 covers the opening of the container body 20, the locking buckle 3 extends into the lower part of the opening edge 21 of the container body 20, when the cover body 10 is tried to be opened, the opening edge 21 of the container body 20 plays a limiting role in the upward movement of the insertion part 3b, and the difficulty is increased for the opening of the cover body 10.

The specific flow of the sealing locking buckle assembly type cover body 10 during installation and use is as follows:

insert part 3b of locking buckle 3 stretches into the inside of lid reason 2 from interface 2a earlier to load locking buckle 3 in lid reason 2 department, leave the space (the space is filled by opening border 21, not shown) between insert part 3b and the inner wall of lid body 1. In the process of sealing the lid 10 and the container body 20, the lid 10 is pressed downward in the direction opposite to the opening direction of the container body 20. In the process of pressing down the cover 10 and gradually sealing the container body 20, the opening edge 21 of the container body 20 contacts with the insertion part 3b of the locking buckle 3 and slides relatively. Along with the continuous push down of lid 10, opening border 21 slides to aforementioned space to keep bayonet joint portion 3b to insert the below of opening border 21, even the state that the tip tightly supported in the outer wall of container body 20, container body 20 is fixed with locking buckle 3 block at opening border 21, forms the card dead structure between lid 10 and the container body 20, thereby plays the effect of blocking the opening lower limb of container body 20, lid 10 and container body 20 are difficult for being opened.

Briefly, the cover 10 is assembled in place in advance to form the locking buckle 3, and in the pressing process of tightly covering the container body 20 with the cover 10, the locking buckle 3 assembled in place in advance slides down between the cover 10 and the upper opening of the container body 20 along the tightly covering direction of the cover 10 by using the gap between the cover 10 and the upper opening of the container body 20, so that the container body 20 is completely covered tightly, and the specified position required for the structure designed for blocking and playing the role of blocking is just reached.

In this embodiment, the locking buckle 3 is first assembled on the lid 10, and then the lid 10 with the locking buckle 3 is covered on the container body 20. In other embodiments it may also be: the cover body 10 without the locking buckle 3 assembled in advance is completely covered on the container body 20, and then the locking buckles 3 are respectively installed in the reserved insertion ports 2a on the cover edge 2 of the cover body 10, so that the same sealing and the function of preventing others from opening without permission are achieved.

In particular, there are various ways of pre-mounting the locking clip 3 on the sealing cover 10 during the production process, including but not limited to manual mounting, manual mounting using various tools, mechanical full-automatic mounting, etc., which are not limited to a certain method or methods and are not necessarily exemplified in detail.

When the user uses great force to remove the cover body 10, certain damage such as deformation, breakage and the like to the cover body 10, particularly the cover edge 2 is inevitable, whether the cover body 10 is opened or not can be intuitively perceived from the appearance, and the condition that the user is unaware of the fact that food is stolen to be opened, and articles are stolen or damaged is avoided. At the same time, the anti-theft device can also play a role in deterring people who attempt to steal or destroy the articles in the sealed container, and reduce the possibility of the attempted steal and destruction.

In addition, the locking buckle 3 and the cover edge 2 are detachably connected, so that the production process flow of the cover body 10 and the installation steps of the locking buckle 3 can be simplified, and the production efficiency is improved. Locking buckle 3 and lid are along 2 detachable connections, can also reduce the degree of difficulty and the cost of the mould preparation of production lid 10, promote the life of mould greatly. Once the locking buckle 3 or the cover body 1 and the cover edge 2 are damaged, only the damaged part can be replaced.

The number of the locking buckles 3 is more than one, and the preferred number is 3-8, and the plurality of locking buckles 3 can be uniformly or non-uniformly arranged on the periphery side of the cover edge 2.

The cover edge 2 is provided with a vertical slot 2b, and the vertical slot 2b is connected with the edge of the cover edge 2 through a breakable connection point 2 c. Due to the arrangement of the vertical slots 2b, the breakable connection points 2c are easily broken under the action of external force. When the lid body 10 is opened, the lid edge 2 is forced to break the breakable connection point 2c, and the lid body 10 can be opened smoothly by continuing the force. Thus, after the lid body 10 is opened, the breakable connection point 2c is broken, the side edge of the lid edge 2 is tilted outward, and the original shape cannot be restored, so that whether the lid body 10 is opened or not can be clearly distinguished from the appearance. The sealing and locking snap-fit type cover body 10 provided by the embodiment can effectively prevent the opening of the container body 20 from being opened intentionally or unintentionally before being delivered to the user's hand during the transportation of the sealed container, thereby increasing the sealing performance and the anti-theft performance of the sealed container.

It should be noted that the destructive opening of the lid rim 2 during the opening process may be varied, including and not limited to all forms described herein, and other forms related to the technical design of the patent structure, which are not specifically illustrated and described herein for reasons of descriptive space and limited space.

The cover edge 2 is provided with a reinforcing rib 2d at the edge of the vertical slot 2b and/or the socket 2a, and in the embodiment, the cover edge 2 is provided with a reinforcing rib 2d at the edge of the vertical slot 2b and the socket 2 a. Through set up strengthening rib 2d in vertical type fluting 2b department, improve the structural strength of here, when trying to open lid 10, the application of force is concentrated and is shifted to breakable tie point 2c department, and the fracture takes place in breakable tie point 2c for lid 10, reminds user's lid 10 to be destroyed, opened.

And through set up strengthening rib 2d in interface 2a department, improve the structural strength of this department, then can be in locking buckle 3 and lid reason 2 assemble or the in-process of dismantling, guarantee that lid reason 2 is difficult for taking place to warp in this department, protect the structural stability of lid reason 2 in this department.

The insertion portion 3b includes an insertion section 3b1 and an abutment section 3b2, and the insertion section 3b1, the abutment section 3b2 and the buckle body 3a are formed in a U-shaped groove shape with the buckle body 3a as a groove bottom. When the locking catch 3 is assembled with the lid edge 2, the insertion section 3b1 is arranged closer to the lid body 1, and the length of the abutment section 3b2 extending into the lid edge 2 is greater than the length of the insertion section 3b1 extending into the lid edge 2. Preferably, the abutment section 3b2 is preferably spaced from the insertion section 3b1 by 1-1.2 mm. More preferably, the distance between the abutting section 3b2 and the outer wall of the container body 20 is not more than 2 mm.

Thus, when the cover 10 is used to close the container body 20, the insertion section 3b1 is just clamped under the opening edge 21 of the container body 20, the length of the insertion section 3b1 can ensure the smoothness of the closing process of the cover 10, and the cover 10 can also be clamped with the opening edge 21 of the container body 20 when the cover 10 is closed in place, so as to firmly clamp the cover 10 and the container body 20 together. The abutment section 3b2, which is longer than the insertion section 3b1, extends toward the container body 20, and when the cover 10 is attempted to be opened, the abutment section 3b2 moves upward, gradually abuts against the edge of the container body 20 and is caught by the opening edge 21 of the container body 20, and if the cover 10 is further opened, the cover 10 and even the container body 20 are inevitably damaged. In other words, the provision of the abutting section 3b2 ensures that the cover 10 is not opened without spoiling the appearance.
