DETAILED DESCRIPTION OF THE EMBODIMENTS

The concept, specific structures, and produced technical effects of the disclosure are clearly and thoroughly described below with reference to the embodiments and the accompanying drawings for thorough understanding of the objectives, features, and effects of the disclosure.
Obviously, the described embodiments are merely some embodiments of the disclosure, rather than all the embodiments of the disclosure. Based on the embodiments of the disclosure, all other embodiments derived by a person skilled in the art without any creative efforts shall fall within the protection scope of the disclosure.
In addition, all connection relationships involved herein do not merely mean that members are directly connected, but instead, a connection accessory may be added or reduced according to specific implementation cases to form a preferred connection structure. All technical features in the disclosure can be combined with each other without causing any contradictions.
As shown in FIG. 1, a storage jar in this embodiment includes a jar body 10 and a lid body 20.
The jar body 10 is provided with an accommodating cavity for accommodating stored substances. The accommodating cavity is provided, at a top of the cavity, with an opening for filling or taking out the stored substances.
The lid body 20 is arranged at the top of the jar body 10 and may cover the accommodating cavity, so that substances in the accommodating cavity are separated from outside.
As shown in FIG. 1, the jar body 10 has a cross section of approximately rectangular shape. Certainly, circular, elliptical, polygonal designs, among other designs, may all be possible.
As shown in FIG. 1, FIG. 2, and FIG. 4, in some embodiments, a first groove 12 is provided in a side wall of the jar body 10, and the first groove 12 is provided in an outer surface of the jar body 10. Therefore, the first groove 12 increases the strength of the jar body 10, and the jar body 10 is less susceptible to deformation, so that the jar body 10 can be vertically placed.
The first groove 12 may have a triangle shape as shown in the figures or may be of another design, which is set according to requirements.
For convenient manufacturing, the first groove 12 may be communicated with the bottom wall of the jar body 10. In this way, the first groove 12 can be directly demolded without having to arranging a complex structure such as a wedge.
To make it convenient to move the storage jar, the cross sectional area of the first groove 12 may increase in a direction towards the bottom wall of the jar body 10.
The increase of cross sectional area of the first groove 12 in the direction towards the bottom wall of the jar body 10, on one hand, is convenient to demold the jar body 10, and on the other hand, facilitates a finger to extend into the first groove 12 to lift the storage jar, and the finger tends to move towards the top of the first groove 12. However, in this case, the cross sectional area of the first groove 12 gradually decreases, and the jar body 10 does not fall off easily from a hand, so that it is convenient to move the storage jar with both hands.
Furthermore, when a protrusion is formed in the accommodating cavity to form the first groove 12 in the jar body 10, the cross sectional area corresponding to the protrusion decreases in the direction towards the top of the jar body 10, so that substances are conveniently poured from the accommodating cavity.
Certainly, different positions of the first groove 12 may be held according to the size of a hand to satisfy an actual requirement.
To make it convenient to hold the jar body 10, the first groove 12 may be provided in the side wall of the jar body 10 in the thickness direction. People tend to hold the jar body 10 in the thickness direction to move the storage jar, and therefore, the provision of the first groove 12 in the side wall of the jar body 10 in the thickness direction makes it very convenient to put a finger in the first groove 12.
Certainly, there may be a plurality of first grooves 12 distributed on two opposite sides of the jar body 10.
As shown in FIG. 1, FIG. 2, and FIG. 4, in some embodiments, the jar body 10 is provided with an end surface abutting the lid body 20, a first turnup 11 is provided at an edge of the end surface, and the lid body 20 is accommodated within an inner side of the first turnup 11.
On one hand, the first turnup 11 expands the sectional profile of the jar body 10 to facilitate the entry of the stored substances into the accommodating cavity without scattering and leakage. On the other hand, the first turnup 11 enables an inner side of the jar body 10 to be arranged in a step form, and gradually becomes smaller from the first turnup 11 to the bottom wall of the jar body 10, so that the jar body 10 may be manufactured using a process other than blow molding. In addition, the jar body 10 has uniform wall thickness, high quality, and low costs. Furthermore, the first turnup 11 does not impede the discharge of substances in the accommodating cavity during being poured, so that the accommodating cavity can be completely emptied.
The jar body 10 may be made of a transparent plastic material. Through the transparent jar body 10, the number and quality of substances in the jar body 10 can be conveniently observed, so that it is convenient to estimate how long the substances can last and make a preparation in advance.
As shown in FIG. 1, FIG. 2, and FIG. 3, in some embodiments, the lid body 20 may be provided with a second turnup 22 covering an end portion of the first turnup 11. The second turnup 22 covers the end portion of the first turnup 11, that is, covers the top of the first turnup 11, so as to prevent dust or the like from entering the accommodating cavity through a gap between the lid body 20 and the first turnup 11, thereby protecting stored substances from pollution.
In addition, the lid body 20 may further be taken out from a space defined by the first turnup 11 by tilting the second turnup 22, so that the lid body 20 is conveniently opened and closed.
In some embodiments, the lid body 20 may be provided with a raised portion 21 which is arranged on a side of the lid body 20 facing away from the jar body 10.
The raised portion 21 is raised towards the side of the lid body 20 facing away from the jar body 10. Therefore, the raised portion 21 may serve to form a portion for a hand to pick up and put down the lid body 20 conveniently. In addition, the raised portion 21 may be designed as a thin shell to increase the storage space of the storage jar. Certainly, the raised portion 21 may also help to increase the strength of the lid body 20.
In some embodiments, the lid body 20 may be provided with a second annular groove 23, and the raised portion 21 is arranged on an inner side of the second annular groove 23. The second annular groove 23 can increase the strength of an edge of the raised portion 21, thus reducing the risk of breakage of the edge of the raised portion 21 during disassembling.
The second annular groove 23 and the raised portion 21 may be arranged at the same side of the lid body 20 or at different sides. That is, one of the second annular groove 23 and the raised portion 21 is located at a side of the lid body 20 facing the jar body 10, and the other is located at the other side of the lid body 20 facing away from the jar body 10.
The second annular groove 23 may be a single groove or may be a plurality of grooves arranged in a circle surrounding the raised portion 21 to produce the same effect.
As shown in FIG. 1 and FIG. 2, in some embodiments, a buckling structure 30 is provided between the lid body 20 and the jar body 10 for detachably connecting the jar body 10 to the lid body 20.
Specifically, the buckling structure 30 includes a buckling arm 31 and a buckling portion 32 engaged with each other. The buckling arm 31 is provided with a hand-held portion 33. The hand-held portion 33 may be a half-moon arc-shaped plate as shown in the figures. Certainly, the hand-held portion 33 may have another shape provided that a force-applying point for a hand is provided.
When the lid body 20 needs to be removed, the hand-held portion is pulled with a finger 33 to further disengage the buckling arm 31 from the buckling portion 32 to open the buckling structure 30.
When the lid body 20 needs to be assembled, the hand-held portion 33 is pulled in the opposite direction to bring the buckling arm 31 to approach the buckling portion 32, so as to buckle the buckling structure 30 to fixedly connect the lid body 20 to the jar body 10.
To achieve more reliable buckling, the buckling arm 31 may be provided with a first hole portion 35 for accommodating the buckling portion 32.
Therefore, the buckling arm 31 is pulled to allow the buckling portion 32 to be inserted into the first hole portion 35 so as to connect the buckling portion 32 to the buckling arm 31 accurately and reliably, and it is convenient to visually confirm the connection.
In some embodiments, to prevent the buckling arm 31 from naturally disengaging from the buckling portion 32, as shown in FIG. 2, the buckling portion 32 may be provided with an anti-disengaging convex portion 34 or an anti-disengaging concave portion.
The anti-disengaging convex portion 34 or the anti-disengaging concave portion abuts an edge of the first hole portion 35, so that on one hand, the buckling portion 32 is prevented from being disengaged from the first hole portion 35 under the effect of a static force, and on the other hand, the anti-disengaging convex portion 34 or the anti-disengaging concave portion may further guide the buckling portion 32 to pass through the first hole portion 35, thus reducing resistance of the buckling portion 32 passing through the first hole portion 35.
The buckling portion 32 has a plate form, and the cross sectional shape of the buckling portion 32 is set to be curved and/or bent. By being curved and/or bent, it is meant that the cross section of the buckling portion 32 may have an arc shape, a semicircular shape, a shape of a door frame, a frame shape or a shape formed of a plurality of straight segments connected sequentially.
Such unique design of the buckling portion 32 not only facilitates the manufacturing of the buckling portion 32, but also increases the strength of the buckling portion 32, so that the buckling portion 32 is durable and less susceptible to damage.
Certainly, the number of the buckling structure 30 is not limited to one and may be increased or reduced according to the shape of the storage jar.
In the process of opening and closing the storage jar, due to the fact that it is necessary to tile the buckling arm 31 and overcome the resistance of the buckling portion 32, the buckling arm 31 are at the risk of fracturing after repeated use. In addition, when there are more buckling structures 30, the buckling arm 31 is more likely to fracture.
As shown in FIG. 2, a limiting structure 40 is further provided between the jar body 10 and the lid body 20. The limiting structure 40 and the buckling structure 30 are arranged offset from each other in a circumferential direction of the jar body 10. The limiting structure 40 and the buckling structure 30 cooperate to fix the lid body 20 to the jar body 10.
The limiting structure 40 and the buckling structure 30 being arranged offset from each other in the circumferential direction of the jar body 10 means that the limiting structure 40 and the buckling structure 30 are arranged at an outer edge of the jar body 10 and do not overlap, thus the limiting structure 40 and the buckling structure 30 can fixedly connect the lid body 20 to the jar body 10. Because the jar body 10 may have various shapes, the limiting structure 40 and the buckling structure 30 are not necessarily located on opposite sides of the jar body 10.
In this embodiment, taking a line vertically passing through the center of the opening of the accommodating cavity as an axis, the direction of rotation around the axis on an periphery of the jar body 10 is the circumferential direction of the jar body 10, and the direction of a vertical connecting line of the periphery of the jar body 10 and the axis is the radial direction of the jar body 10.
The limiting structure 40 and the buckling structure 30 are preferably arranged on opposite sides of the jar body 10 in the thickness direction, so that the number of the limiting structures 40 and the number of the buckling structures 30 are reduced.
In some embodiments, the limiting structure 40 includes a limiting member 41 and a limiting hole 42 for accommodating the limiting member 41, and the limiting hole 42 has an axis extending in the radial direction of the jar body 10.
The limiting member 41 is conveniently disengaged from the limiting hole 42 to facilitate the disassembling of the storage jar. Moreover, the limiting member 41 and the limiting hole 42 are conveniently formed during manufacturing, and the process is simplified.
In some embodiments, the limiting member 41 has a plate form, and the limiting hole 42 extends in the circumferential direction of the jar body 10 and is strip-shaped.
In this way, on one hand, the strength of the limiting member 41 can be increased to prevent the limiting member 41 from being broken, and on the other hand, it can be ensured that the lid body 20 reliably covers the jar body 10 without increasing the number of limiting structures 40.
In some embodiments, the limiting member 41 has a plate form, and the cross sectional shape of the limiting member 41 is set to be curved and/or bent, which has the same advantage as described with respect to the buckling portion 32, and it further allows for varied designs.
Certainly, the limiting structure 40 is not limited to the limiting member 41 and the limiting hole 42 for accommodating the limiting member 41. The limiting hole 42 may be alternatively a concave groove, an opening, a hook portion or the like.
By such improvement, when removing the lid body 20 from the jar body 10, the lid body 20 may be pushed towards or pushed away from one side of the buckling structure 30, and the buckling structure 30 is then operated to complete the removal, so that the required travel distance of the buckling structure 30 can be reduced, which in turn reduces the deformation of the buckling structure 30 and the possible damage of the storage jar during opening and closing, and thus increases the reliability of the storage jar. In another aspect, by arrangement of fewer buckling structures 30 on the storage jar, it reduces the difficulty to manufacture the storage jar and thus reduces the manufacturing costs. In addition, the foregoing structure is also applicable to containers such as food containers and crispers, which achieves the same effect and can be widely applied and popularized.
As shown in FIG. 2 and FIG. 3, in some embodiments, the lid body 20 is provided with a flange within the accommodating cavity, a sealing ring 50 is sleeved on an outer side of the flange, and the sealing ring 50 and the accommodating cavity fit together to form a seal.
Because the buckling structure 30 and the limiting structure 40 fixedly connect the lid body 20 to the jar body 10, the direction of a force experienced by the buckling structure 30 and the limiting structure 40 is the direction of a connecting line between the lid body 20 and the jar body 10, and the direction of a force experienced by the sealing ring 50 on the flange is perpendicular to a side wall of the accommodating cavity. Therefore, the directions of the two forces are approximately perpendicular. That is, the force experienced by the sealing ring 50 and the force experienced by the buckling structure 30 and the limiting structure 40 affect each other slightly or do not affect each other. The sealing performance of the storage jar is only related to the sealing ring 50 and is insusceptible to the opening and closing of the structure. Moreover, the opening and closing of the structure is not affected by the sealing ring 50, so that it is less difficult to open or close the storage jar. In addition, the sealing ring 50 is sleeved on the outer side of the flange, and the sealing ring 50 and the lid body 20 can be securely fixed without any glue, so that the storage jar is sanitary and environmentally friendly.
In some embodiments, the lid body 20 is provided with a first annular groove, and the flange is arranged on an inner side of the first annular groove. The first annular groove may have the same features as the second annular groove 23 or may be additionally arranged.
Similarly, the first annular groove increases the strength of the lid body 20 which is therefore less susceptible to deformation during assembly, so that it is ensured that the lid body 20 can tightly cover the jar body 10.
In some embodiments, the jar body 10 is provided with an end surface abutting the lid body 20, and a sealing ring 50 is provided between the end surface and the lid body 20. The arrangement of the sealing ring 50 on the end surface enables that the space of the accommodating cavity is not occupied. In addition, it is convenient to replace the sealing ring, and suitable resilience of a sealing gasket further keeps the buckling structure 30 and the limiting structure 40 from loosening easily.
In some embodiments, the buckling structure 30 and/or the limiting structure 40 is arranged at the first turnup 11, so that the formation of the accommodating cavity is not affected and the volume of the accommodating cavity is not reduced. The first turnup 11 may further deform to increase the elasticity of the buckling structure 30 and the limiting structure 40, and the buckling structure 30 and the limiting structure 40 are less susceptible to partial deformation and thus less likely to fracture. In addition, the entire storage jar has a simple and elegant appearance.
The buckling structure 30 and/or the limiting structure 40 being arranged at the first turnup 11 means that the buckling structure 30 and limiting structure 40 may be separately arranged on the first turnup 11 or may be both arranged on the first turnup 11.
The foregoing embodiments are not limited to the technical solutions in the embodiments, and the embodiments may be combined with each other to form a new embodiment. The foregoing embodiments are only intended to describe the technical solutions of the disclosure rather than to limit the technical solutions. Any modification or equivalent replacement made without departing from the principle and scope of the disclosure shall fall within the scope of the technical solutions of the disclosure.
