Description

Glue caps and glue bottles

technical field

The invention belongs to the technical field of packaging, and in particular relates to a packaging bottle and a bottle cap of glue.

Background technique

In the prior art, glue such as anaerobic glue is usually put into the bottle body, and the bottle cap is a combined structure composed of an inner cover and an outer cover. The inner cover is fixedly connected to the bottle body, and the outer cover is fixedly connected to the inner cover. The inner cover is opened to facilitate the filling of glue in the production line. The glue outlet is set on the upper end of the inner cover. When in use, the bottle is squeezed to make the glue flow out. The function of the outer cover is to close the glue outlet on the inner cover, so that the unused glue can be reused once. Such glue products are, for example, 271 glue, 270 glue, 222 glue, 340 glue, 680 glue, 555 glue, etc.

The disadvantage of such a glue bottle is that the glue bottle cannot be placed upright after the glue outlet is sealed by the outer cover once the glue is not used up. Once the glue bottle is toppled or deflected, glue will flow into the area between the glue outlet and the outer cover. After opening the outer cover again, this part of the glue will be lost and wasted, and the flowing glue will also cause pollution. Not only caused inconvenience but also wasted cost. Especially for low-viscosity glue, this kind of imaging is more obvious.

In the prior art, in order to solve this problem, there is a structure in which a tapered plug is arranged in the outer cover at a position corresponding to the glue outlet. When the outer cover is tightened, the tapered plug is inserted into the glue outlet to close the glue outlet. . However, in such a structure, when using the outer cover, a centering operation is required, which is still inconvenient to use.

Contents of the invention

The object of the present invention is to provide a more convenient glue bottle cap and a glue bottle using the glue bottle cap.

In order to achieve the above object, the present invention adopts the following technical solutions: a glue bottle cap, which is characterized in that: it includes an inner cover, a middle cover and an outer cover coaxially arranged, the inner cover is used to be fixedly connected to the bottle body, and the middle cover and the The parts between the inner covers are socketed and a flow control mechanism is set, the middle cover slides relative to the inner cover and the linkage flow control mechanism opens or closes the fluid channel arranged in the axial direction, and the fluid channel communicates with the glue outlet and the inner cavity of the inner cover; The outer cover and the inner cover are threadedly connected, and elastic buckles are provided between the outer cover and the middle cover. During the threaded connection process of the outer cover and the inner cover, the elastic buckles make the positions of the outer cover and the middle cover relatively fixed.

The technical scheme of the glue bottle using the glue bottle cap is: the glue bottle is threadedly connected by the internal thread on the inner cover and the external thread on the mouth of the bottle body.

The beneficial effects of the present invention are: in the above structure, a middle cover is added, so that the middle cover slides axially or radially, and the flow control mechanism can be opened, so that the fluid channel is opened, and the glue can flow from the bottle to the glue outlet. ; or keep it closed to avoid glue from staying out. In order to utilize this sliding mechanism to control whether the glue can flow out, it is easy to use. The present invention is equipped with an elastic buckle; the elastic buckle can keep the middle cover and the outer cover relatively fixed in the axial or radial position, so that in the process of screwing in the outer cover, when the buckle is engaged, the inner cover , the outer cover is kept in sync, and the continuous rotation of the outer cover will make the middle cover slide with it relative to the inner cover, so that the fluid channel is closed and the glue cannot be left; otherwise, in the process of loosening the outer cover, the outer cover will naturally drive the middle cover. The cover moves, and the middle cover slides in reverse to open the fluid channel so that the glue can be poured out again after removing the outer cover. Such a structure prevents the glue from being lost and wasted, and at the same time, it is very convenient to use and can maintain the same use method as the prior art.

Detailed ways

A kind of glue bottle cap as shown in Fig. 1 to 5, comprises inner cap 20, middle cap 30 and outer cap 40 arranged coaxially, and inner cap 20 is used for being fixedly connected with bottle body 10, and the present invention is preferred and most A convenient technical solution is that the glue bottle is threaded through the inner thread on the inner cover 20 and the outer thread of the mouth of the bottle body 10 to form a glue packaging bottle. The middle cover 30 is socketed with the inner cover 20 and a flow control mechanism is provided. The socket of the middle cover 30 and the inner cover 20 is specifically, the inner ring 21 on the upper part of the inner cover 20 is inserted into the lower end of the middle cover 30, and both The pipe diameters match. The flow control mechanism is affected by the sliding action of the middle cover 30 and the inner cover 20 to open or close the fluid channel arranged in the axial direction; the inner wall of the lower end of the outer cover 40 is provided with internal threads, and the outer ring 22 on the upper part of the inner cover is provided with external threads , the two form a threaded connection; an elastic buckle is provided between the outer cover 40 and the middle cover 30, and the elastic buckle is engaged with the outer cover 40 and the middle cover 30 when the outer cover 40 is screwed onto the inner cover 20 or disassembled. The location is relatively fixed. There are many specific implementations of the flow control mechanism and the elastic buckle in the above technical solution, which are mainly divided into: when the middle cover 30 and the inner cover 20 can slide radially, the elastic buckle is designed to make the outer cover 40 and the inner cover 20 slide The radial position of the middle cover 30 is relatively fixed, so that when the outer cover 40 is screwed in, the middle cover 30 is driven to slide in the radial direction and close the fluid passage; otherwise, the fluid passage is opened during the unscrewing process. As long as the direction in which the outer cover 40 is screwed in or out is corresponding to the opening or closing of the fluid channel when the structure is set.

In other words: the flow control mechanism and the elastic buckle of the present invention are mainly arranged in two ways: the flow control mechanism is a structure that opens or closes the fluid channel when the middle cover 30 slides in the axial direction; The elastic buckle is a structure for relatively fixing the positions of the outer cover 40 and the middle cover 30 along the axial direction. Alternatively, the flow control mechanism is a structure that opens or closes the fluid channel when the middle cover 30 slides in the radial direction; the elastic buckle is a structure that makes the outer cover 40 and the middle cover 30 relatively fixed in the radial direction.

Specifically, taking the technical solution of sliding in the axial direction as an example, the preferred embodiment can be as shown in Figures 1 and 2. The bump 41 is matched with the annular groove 31; the flow control mechanism includes a round hole provided on the upper end of the inner cover 20, and a number of slits 11 are set in the round hole divergent outward, and the inside of the middle cover 30 is passed through the supporting legs or belts. The support plate of the through hole is fixedly connected with a core rod 33, and the bottom of the core rod 33 is inserted in the round hole in an anastomotic manner, and the end of the core rod 33 located in the inner cover 20 is fixed with a stopper 331; the stopper ( 331) is in the shape of a stepped shaft arranged coaxially with the core rod (33), the upper end of which is a truncated cone whose size gradually increases downwards, the middle is a circular shaft section whose diameter coincides with the lower end of the truncated cone, and the lower end is the end with the largest diameter head.

Combining the state shown in Figures 1 and 2, in such a structure, the outer cover 40 is threadedly connected to the outer thread 21 on the inner cover 20 through the inner thread of the inner wall, at this time, the protrusion 41 and the annular groove 31 constituting the elastic buckle They are fastened together. When glue is to be used, unscrew the outer cover 40. When the outer cover 40 is first rotated, the outer cover 40 and the middle cover 30 must maintain a relatively fixed position in the axial direction. As the rotation proceeds, When the outer cover 40 moves upward as shown in the figure, the fixed core rod 33 in the middle cover 30 must also move upward, and since the upper part of the stopper 331 is in the shape of a truncated cone, this movement must be very smooth. Of course, in such a structure, because the core rod 33 is in the shape of a rotating body, whether the outer cover 40 and the middle cover 30 rotate with each other does not affect the use of glue. Therefore, the annular groove 31 only needs to be arranged axially along the middle cover 30 to ensure that the projection 41 can be snapped in, and it does not matter whether the annular groove 31 penetrates along the peripheral surface. When the core rod 33 rises to the center of the circular shaft section and contacts the edge of the circular hole, the end of the stopper 331 will otherwise form a position-limiting structure for the centering cover 30 because the size is too large. At this time, the projection 41 and the annular groove 31 Under the force of further rotating the outer cover 40, they are separated from each other, and the purpose of opening the bottle cap and opening the fluid passage is completed. On the stopper 331, the circular shaft section and the end end cooperate with the edge of the circular hole so that the middle cover 30 will not slide and fall. As shown in Fig. 5, the plurality of sealing sheets 12 formed by the cutout 11 on the inner cover 20 must be separated from each other, then the glue can flow out through the cutout 11, and then leave through the glue outlet 32 provided on the upper end of the middle cover 30, which is very convenient to use. convenient.

After use, in the process of screwing in the outer cover, the elastic buckle snaps in, and the middle cover 30 is pushed by the outer cover and moves downward to return to the state shown in Figure 1, realizing the sealing of the fluid channel and preventing the glue from being It is reserved by the glue outlet 32 under the situation of use. Because the inner cover 20 , the middle cover 30 and the outer cover 40 are all made of plastic, they have better elasticity and are more convenient for fastening of the elastic buckles.

A further improvement is: 3 to 5 cutouts 11 are provided. In this way, the number of sealing pieces 12 is reasonable, which can reduce the rising resistance of the stopper 331, the core rod 33 and the entire middle cover 30, and facilitate processing at the same time.

The circular hole on the inner cover 20 and the core rod 33 are arranged along the axis of the inner cover 20 , and at least three supporting legs are arranged symmetrically along the core rod 33 . Such a symmetrical structure is more conducive to uniform stress on each component, reduces the possibility of local damage, and improves product life. The supporting legs or the supporting plate to the through hole are all for ensuring fluid circulation, and there is no special requirement for the specific structure.

At least two of the protrusions 41 are evenly arranged along the inner peripheral surface of the outer cover 40 . Although the middle cover 30 and the outer cover 40 are all made of elastic materials such as plastic, the structure of the middle cover 30 will not be damaged when the bump 41 squeezes the middle cover 30, but in order to reduce wear and reduce elasticity For buckle fastening and separation force, it is more appropriate to evenly arrange 2 to 4 bumps 41 .

The bump 41 is in the shape of a hemisphere or a prismatic shape with a U-shaped cross section. As shown in Figure 3 and 4. That is to say, the surfaces in contact with the annular groove 31 have a smooth transition, and the wear and resistance of fastening or separation are relatively small.

As for the structure that slides in the radial direction, because the middle cover 30 can be rotated radially to communicate with the fluid channel, there are many ways for the glue to flow out. Usually, a through hole is set on the middle cover and the inner cover, and when it is rotated to the position corresponding to the empty opening, the Glue can be produced, and the orifice will be closed when the position is staggered. Correspondingly, the technical concept of the present invention should be used to facilitate the use. The corresponding elastic buckle only needs the corresponding ribs on the inner walls of the middle cover 30 and the outer cover 40, so that when the outer cover 40 is screwed in, the middle cover 30 Rotate in sync with it.

In the various preferred embodiments described above, a further improvement that can be made is: the glue outlet 32 at the upper end of the middle cover 30 is in a sharpened shape. Combined with those shown in Figures 1 and 2. The glue outlet 32 itself can be closed, and then cut to form by the user; but because the general anaerobic adhesive does not need to be strictly isolated from the air, the present invention preferably pre-sets the liquid outlet 32, which is convenient for the user to directly use. And the liquid outlet 32 is processed into a sharpened shape, which is designed in conjunction with anaerobic adhesives that are generally applied to anaerobic environments such as slits. The sharpened shape can facilitate glue coating into the slit.

The invention is suitable for the packaging of most glues, especially for anaerobic glues with low viscosity, and can also be used for product packaging with similar physical and chemical properties, and achieves corresponding technical effects.
