Description
Technical Field
The utility model relates to a drinking container, in particular to a cup structure.
Background
The thermos cup is one of the most commonly used drinking vessels in people's life, and the thermos cup generally comprises an inner container and a shell, wherein the shell is formed by welding after aligning the upper part of the shell with the bottom of the shell, but because the shell is thinner, the upper part of the shell and the bottom of the shell are not perfectly round, more air gaps can exist after aligning the upper part of the shell and the bottom of the shell in practice, and the joint of the upper part of the shell and the bottom of the shell is sometimes not completely sealed after the welding is finished, so that the heat preservation effect of the thermos cup is affected. In addition, because the bottom of the existing shell is too high, after welding is finished, an obvious welding line is reserved at the welding part at the lower part of the side of the cup body, so that the whole appearance is influenced, and improvement is needed.
Disclosure of Invention
Aiming at the defects that the joint between the upper part of the shell and the bottom of the shell is sometimes not completely sealed after welding in the prior art, thereby affecting the heat preservation effect of the vacuum cup, and an obvious welding line is reserved at the lower part of the side part of the cup body after the welding is finished, the utility model provides a novel cup structure.
In order to solve the technical problems, the utility model is realized by the following technical scheme:
the utility model provides a cup structure, includes shell upper portion, shell bottom and inner bag, and the oral area on shell upper portion is connected with the oral area of inner bag, and the shell bottom is provided with the vacuum hole, and vacuum hole department is provided with the solder, the bottom of shell upper portion incurvate form upper portion connecting portion, be provided with the through-hole on the upper portion connecting portion, the upper surface of shell bottom with the laminating of the lower surface of upper portion connecting portion just the shell bottom covers the through-hole, the edge of shell bottom with upper portion connecting portion welding.
On the one hand, the bottom of the upper part of the shell is inwards bent to form the upper connecting part, the welding part of the upper part of the shell and the bottom of the shell can be transferred to the bottom of the whole cup, and then the welded welding line only appears at the bottom of the cup, so that the side of the whole cup is flat and as one, and the aesthetic property of the cup is improved. On the other hand, because the upper surface of shell bottom is laminated with the lower surface of upper portion connecting portion, then be the laminating of face and face between shell bottom and the upper portion connecting portion, greatly reduced the counterpoint requirement before the welding, can not lead to there is air gap after upper portion connecting portion and the shell bottom counterpoint, then the edge of shell bottom and upper portion connecting portion post-weld leakproofness are better, have realized full seal, have promoted welded qualification rate, can reach better heat preservation effect.
Preferably, in the cup structure, the upper surface of the bottom of the shell is a plane, and the area of the lower surface of the upper connecting portion, which is attached to the upper surface of the bottom of the shell, is a plane.
The upper surface of the bottom of the shell and the lower surface of the upper connecting part are both arranged to be plane, so that the contact area of the upper surface of the bottom of the shell and the lower surface of the upper connecting part is greatly increased, the air gap after alignment can be better eliminated, and the sealing effect after welding is better.
Preferably, in the cup structure, the middle part of the bottom of the shell is concaved inwards to form a cap, the cap surrounds to form a groove, and the vacuum cavity and the solder are located in the groove.
Through the arrangement of the structure, after vacuumizing is finished, the vacuum cavity can be better blocked by the solder.
Preferably, in the cup structure, the upper connecting portion forms a step, a step straight surface is formed on the step, the bottom of the shell is located in the step, the upper surface of the bottom of the shell is attached to the step straight surface, and the edge of the bottom of the shell is welded with the step.
The step formed by the upper connecting part is attached to the upper surface of the bottom of the shell, so that the position of the bottom of the shell is more stable and no deviation occurs.
Preferably, in the cup structure, the width of the step straight surface is 5.5 mm to 6.5 mm.
Through limiting the width of the step straight surface to the above range, the plane contact area of the bottom of the shell and the step straight surface can be ensured on one hand, the occurrence of an air gap is avoided, and on the other hand, a space for giving way can be provided for a vacuum cavity, so that the vacuumizing effect is ensured.

fig. 2 is a partial enlarged view of the portion a in fig. 1.
Detailed Description
The utility model is described in further detail below in connection with figures 1-2 and the detailed description, which are not intended to limit the utility model:
example 1
As shown in fig. 1 and 2, a cup structure comprises an upper shell portion 1, a bottom shell portion 2 and a liner 3, wherein the opening of the upper shell portion 1 is connected with the opening of the liner 3, a vacuum cavity 4 is formed in the bottom shell portion 2, a solder 11 is arranged at the vacuum cavity 4, the bottom of the upper shell portion 1 is bent inwards to form an upper connecting portion 5, a through hole 6 is formed in the upper connecting portion 5, the upper surface of the bottom shell portion 2 is attached to the lower surface of the upper connecting portion 5, the bottom shell portion 2 covers the through hole 6, and the edge of the bottom shell portion 2 is welded with the upper connecting portion 5.
Preferably, the upper surface of the housing bottom 2 is a plane, and the area of the lower surface of the upper connecting portion 5 that is bonded to the upper surface of the housing bottom 2 is a plane.
Preferably, the middle part of the bottom 2 of the shell is concaved inwards to form a cover cap 7, the cover cap 7 surrounds to form a groove 8, and the vacuum cavity 4 and the solder 11 are positioned in the groove 8.
Preferably, the upper connecting portion 5 forms a step 9, a step straight surface 10 is formed on the step 9, the housing bottom 2 is located in the step 9, the upper surface of the housing bottom 2 is attached to the step straight surface 10, and the edge of the housing bottom 2 is welded to the step 9.
Preferably, the width of the step surface 10 is 5.5 mm to 6.5 mm.
Specifically, before welding, an operator places the housing bottom 2 with the vacuum cavity 4 on the step 9 formed by the upper connecting portion 5, so that the upper surface of the housing bottom 2 is attached to the step straight surface 10 on the step 9, and the housing bottom 2 is stably limited by the step 9, so that the housing bottom 2 is prevented from being deviated during welding. Because the upper connecting part 5 is formed by inwards bending the bottom of the upper part 1 of the shell, the step 9 is also positioned at the bottom of the whole cup in practice, so that the welding line after the subsequent welding is positioned at the bottom of the cup, the welding line can not be observed from the side of the cup, and the aesthetic degree of the finished product is improved. And as the step straight surface 10 and the bottom 2 of the shell form surface-to-surface contact, the requirement on alignment is greatly reduced, the possibility of forming an air gap is eliminated, the difficulty in welding is lower, and the product qualification rate is improved.
Then, the edge of the case bottom 2 is welded, and the edge of the case bottom 2 is connected to the step 9. Then, solder 11 is placed in the groove 8 of the bottom 2 of the shell and vacuumized, and the vacuum cavity 4 is blocked by the solder 11 after vacuumization is completed, so that the heat preservation function is realized.
In summary, the foregoing description is only of the preferred embodiments of the present utility model, and all equivalent changes and modifications that come within the scope of the present utility model are desired to be covered thereby.
