Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Example 1
As shown in fig. 1 and 2, the utility model discloses a cup joint combination container lid, including the enclosing cover 1 of top, the interior stopper 2 of below, the enclosing cover 1 has upper and lower through-hole, and interior stopper 2 has the appearance chamber of the cylindricality that link up of non-that corresponds with the enclosing cover through-hole, and enclosing cover 1 cup joints together with interior stopper 2 by the fixed lid 3 of cylindricality in order to connect the plug-in mode. The inner plug 2 can also be sleeved with the fixed cover in an injection molding mode, and the cylindrical containing cavity of the inner plug 2 can also be changed into a through hole.
The upper opening of the through hole of the outer cover 1 is expanded to form a flared part 11, and the upper periphery of the fixed cover 3 is provided with a convex edge 31 matched with the flared part 11 of the outer cover 1. The structure plays a role in positioning the insertion depth of the fixed cover 3, thereby not only avoiding the situation of not-in-place insertion, but also preventing the fixed cover 3 from sliding down along the through hole of the outer cover 1 due to the non-fastening of the matching when the cover is pulled out from the container.
In the embodiment, the through hole of the outer cover 1, the cylindrical containing cavity of the inner plug 3 and the fixed cover 3 are all cylindrical, and the sleeve joint parts of the through hole, the cylindrical containing cavity of the inner plug 3 and the fixed cover 3 are convenient to process. As another alternative, the through hole of the outer cover 1, the cylindrical cavity and the fixing cover 3, which are sleeved with each other, are all non-cylindrical, which has the advantage that they do not rotate with each other due to the insufficient tightness of the combination.
In the embodiment, in order to increase the reliability of the insertion between the fixed cover 1 and the inner plug 2 and prevent the axial sliding, the contact surfaces of the fixed cover 1 and the inner plug 2 are provided with the circumferential concave- convex structures 21 and 32 which are matched with each other.
The inner plug 2 is made of flexible materials, and sealing reliability is improved. The upper part of the inner plug 2 extends outwards horizontally to form a sheet ring to form a gasket 22 between the outer cover 1 and the container mouth 4.
The lateral surface of the outer cap 1 is provided with a circumferential annular groove 12, as shown in fig. 3 and 4: the annular groove 12 is matched with the outer edge above the container opening 4 and is provided with a fixing ring 5. The section of the fixing ring 5 is T-shaped, and the upper edge and the lower edge are respectively clamped inwards below the annular groove 12 and the outer edge of the container port 4, as shown by the small circle in figure 3. The fixing ring 5 is used for locking the container cover on the container and can be added with an anti-counterfeiting function. Fig. 4 shows a fixing ring with an anti-counterfeiting tear strip, which is opened in a tearing and destroying manner and cannot be restored after being opened, so that the anti-counterfeiting effect is achieved.
Example 2
The present embodiment is different from embodiment 1 only in the manner of inserting the inner plug 2 into the fixing cap 3, and the rest is the same as embodiment 1.
As shown in fig. 5 to 7, the fixing cover 3 is in the shape of an inverted cylindrical cup, and has four through holes 33 uniformly distributed in the circumferential direction on the lower wall thereof. After the fixed cover is inserted into the outer cover, the inner plug 2 is sleeved on the fixed cover 3 in an injection molding mode. During the injection molding process, the material of the inner plug 2 can enter the inner part of the fixing cover 3 through the through hole 33 and the opening of the fixing cover 3, and as a result, the inner plug 2 wraps the fixing cover 3 inside and outside. Since the material of the inner plug 2 penetrates the through hole 33 of the fixing cap 3, the two are fixed together. As in fig. 7, the left-hand section passes through the through-hole 33, and the material of the inner plug fills the through-hole (see the circled position); the right-hand section does not pass through the through-hole 33, it being possible to clearly see that the inner plug wraps around the wall of the fixed cover.
