Description

Screwless sealing cup cover

The present invention relates to the field of sealed vessels, and more particularly to a threadless sealed cup cover.

In the prior art, the cup of the sealing cup and its lid are usually threaded, that is, at the junction of the two, a thread that can be used in combination is made. For example, an external thread is provided at the mouth of the cup, and an internal thread is provided on the inner wall of the cup cover; or an internal thread is provided at the mouth of the cup, and an external thread is provided on the outer side wall of the cup cover. In the life, the former is used more, but no matter which of the above two structures is used, the following disadvantages cannot be avoided: First, the cup mouth needs to be made into a threaded cup mouth, which increases the manufacturing cost of the cup, and the cup mouth Threads can make the referrer feel uncomfortable and reduce the consumer experience. Second, the thread on the cup and the lid is difficult to clean, which is prone to bacterial problems such as bacterial growth, dust and dirt accumulation.

A non-threaded sealing cup is disclosed in the patents of the Chinese patents ZL201020102745.6 and ZL201010172687.9, and is intended to solve the problem of inconvenient cleaning between the screw-connected sealing cup and the cup cover in the prior art.

For example, as shown in FIG. 1 , a cup cover 40, a sealing gasket 41, a cup body 42, an external thread sleeve 43, a cup holder sleeve 44, a cup handle 45, The hexagonal screw 46 and the positioning piece 47 are formed, the positioning piece 47 is connected with the external thread sleeve 43, the positioning piece 47 is inserted into the cup holder fixing sleeve 44, and the cup sealing is combined by the external thread sleeve 43, the inner threaded buckle of the cup cover 40, and the sealing washer 41. carry out. It can be seen that the opening is completely completed by operating the cup handle 45. The structure of the cup handle 45 is easy to open the cup cover due to misoperation such as collision, extrusion, etc., and the sealing and safety of the cup cover are poor.

Another type of cup is disclosed in Chinese Patent No. ZL201010172687.9, which includes a cup body 30 and a lid 31, and a sealing surface 32 is provided between the cup body 30 and the lid 31. The inner side of the cup body is provided with a slot 33. The cup cover comprises: an upper cover body 34 and a lower cover body 35, and a connecting sleeve 36 is disposed between the upper and lower cover bodies, and the lower cover body is provided with a sliding slot 37, and the slider 38 can be Moving in the chute 37, the slider 38 is provided with a slot 381 which cooperates with the slot. The slider 38 is provided with a return spring 382. One end of the return spring 382 is in contact with the slider 38, and the other end and the lower cover of the return spring 382 are closed. The stoppers 351 on the body 35 are in contact with each other, and the upper and lower covers are rotatable. The upper cover 34 is provided with a push block 341, and the push surface 342 of the push block 341 pushes the slider 38 outward. Due to the non-threaded fit between the cup body 30 and the lid 31 of the Chinese patent ZL201010172687.9, the sealing surface between the cup body and the lid is sealed, eliminating the trouble of repeatedly screwing the lid, the operation is convenient, and the sealing performance is relatively It has been improved, but the mouth of the inside of the cup still needs to be grooved. The grooved part will replace the original thread to cause bacterial problems such as bacterial growth and dirt accumulation, and it still cannot solve the cup mouth hygiene problem fundamentally.

Most of the current sealing cups use a threaded structure to connect the cup body and the cup cover, because the threaded connection is relatively tight in sealing, and the screwed cup lid does not fall off at random, and the safety is also good. However, such a sealed cup inevitably has a thread that is not easy to clean, and the accumulation of dirt is serious, and long-term use is bound to cause bacterial growth, which is not conducive to the health of the drinker.

As a result, the non-threaded sealing cup came into being. Some patents represented by Chinese patents ZL201020102745.6 and ZL201010172687.9 have made research on the field of screwless sealing cups, and developed a series of non-threaded sealing cup products.

However, as mentioned above, the biggest development obstacle facing the current non-threaded sealing cup is how to balance the problems of easy opening and closing and strengthening sealing performance. For example, the non-threaded sealing cup in the Chinese patent ZL201020102745.6, although easy to open and close, but the sealing is not high, easy to be accidentally opened, and the safety is not good.

However, in the Chinese patent ZL201010172687.9, the cup cover is lacking in sealing performance and safety performance, and the main performance is as follows: the cover body is sealed only by the friction of the contact portion with the cup mouth, and the sealing performance is not high, and After long-term use, the inner plug and the rubber sleeve and the like will be aged, and the sealing property will also be lowered; if the cover body does not have a good sealing effect, the liquid inside the cup body is easily splashed by knocking down the cup body. Out, it is detrimental to the security of its use.

In view of the technical problems still existing or potentially more difficult to overcome in the current unthreaded sealed cups, the present invention emerges as the times require.

In view of the above-mentioned existing or potential deficiencies in the prior art, the present invention provides a screwless sealed cup cover, which can effectively avoid the hygiene problems such as bacterial growth, dust and dirt accumulation caused by inconvenient cleaning at the lid and the cup mouth; It can also effectively improve the sealing and safety of the sealed cup.

The production of the unthreaded cup mouth can also enhance the experience of the drinker, and can also fundamentally solve the health problems such as easy to breed bacteria and accumulate dirt due to inconvenient cleaning at the cup mouth, so the drinker can safely divert water. In addition, the advantage of the non-threaded cup lid compared to the threaded cup lid is that the thread of the cup lid in the threaded cup lid rubs against the thread of the cup mouth to produce powder. If it is accidentally drunk, it will hurt the body and the friction will produce sound. There is noise, and the new type adopts a screwless cup cover. Since there is no screw friction, no friction powder will be generated, and no sound and noise will be emitted. At the same time, the inner plug and the rubber sleeve provided on the inner layer structure of the cover body can be stuffed in the mouth of the cup during use, and can function well to seal the mouth of the cup, and can be arranged through the elastic piece and the rib.

The outer layer structure 111 of the cover body 11 is only wrapped on the outer side of the cup mouth, and the contact portion of the outer layer structure 111 with the cup mouth does not need to be provided with a thread. In terms of simplifying the production of the cup mouth, and the unthreaded cup mouth can enhance the experience of the drinker, on the other hand, it can fundamentally solve the health problems such as easy to breed bacteria and accumulate dirt due to inconvenient cleaning at the cup mouth, therefore, the drinker You can safely divert water.

In addition, the advantage of the non-threaded cup lid compared to the threaded cup lid is that the thread of the cup lid in the threaded cup lid rubs against the thread of the cup mouth to produce powder. If it is accidentally drunk, it will hurt the body and the friction will produce sound. There is noise, and the new type adopts a screwless cup cover. Since there is no screw friction, no friction powder is generated, and no sound and noise are emitted. At the same time, the inner plug and the rubber sleeve provided on the inner layer structure of the cover body can be stuffed into the mouth of the cup during use, and can function well to seal the mouth of the cup, and through the elastic piece 14 and The rib 15 is disposed to push the rib 15 outward when the lid body 11 is rotated downward to bring the inner lid of the lid into contact with the rib 15, and is elasticized outwardly with the elastic piece 14. Opening, thereby expanding the outer rubber sleeve 13 , the rubber sleeve 13 fully abuts against the inner wall of the cup opening, so that the lid body 11 is not pulled out; otherwise, rotating the lid body 11 to leave the inner lid of the lid The rib 15 is restored to the original shape, and the cover 11 is loosened, the cover 11 can be pulled out, the operation is convenient, the sealing performance is high, and the use safety is good.

The detailed construction of the present invention is further illustrated by two specific embodiments.

Embodiment 1 : As shown in FIG. 4 to FIG. 7 , the outer wall of the inner plug 12 is provided with a first external thread, and the inner wall of the inner ring of the inner cover structure 112 is provided with a first internal thread, the first outer portion a thread is screwed to the first internal thread, thereby causing the inner plug 12 to be screwed onto the inner layer structure 112, and because the two are screwed to each other, therefore, in the direction in which the first internal thread is disposed The inner plug 12 is movable along the inner ring of the cup cover so as to be close to or away from the cover body 11.

The inner layer structure 112 of the cover body 11 further includes a positioning post 113 located on the inner side of the inner ring of the cup cover, and the inner plug 12 is located between the positioning post 113 and the inner ring of the cup cover. The positioning post 113 is further provided with a stopper stopper 16 . Correspondingly, a slot 160 is defined in the inner plug 12 , and the inner stopper limiting member 16 is locked in the slot 160 and can be along the card. The slot 160 is moved, and the moving direction of the inner stopper limiting member 16 in the latching slot 160 coincides with the moving direction of the inner plug 12 on the inner ring of the cap. The inner plug limiting member 16 is disposed on the positioning post 113. The one end away from the cover body 11 serves to prevent the inner plug 12 from coming off the inner ring of the cup cover, but does not affect the free movement of the inner plug 12 on the inner ring of the cup cover.

Preferably, the inner stopper restricting member 16 is an elastic limiting member, and the lower end of the positioning post 113 is provided with a locking hole 1130. In the embodiment, the positioning post 113 is an inner hollow tubular column, and the inner portion thereof is formed through. The vertical hole can be used in conjunction with the locking hole 1130.

The inner stopper limiting member 16 includes at least one first elastic wing 161 and at least one second elastic wing 162. The first end a of the first elastic wing 161 and the first end b of the second elastic wing 162 are elastically connected and Locked in the locking hole 1130 of the positioning post 113, the second end c of the first elastic wing 161 and the second end d of the second elastic wing 162 are away from each other and extend to the outside of the inner plug 12; The outer walls of the first wing 161 and the second wing 162 are resiliently engaged in the slot of the inner plug 12.

Specifically, the locking mechanism between the first end a of the first elastic wing 161 and the first end b of the second elastic wing 162 and the locking hole 1130 of the positioning post 113 may be: disposed at the mouth of the locking hole 1130 a first locking hook, the first locking hook is inward; a second locking hook is disposed on the outer wall of the first elastic wing 161 and the second elastic wing 162, and the second locking hook is outwardly connected with the first locking hook match. When the first locking hook and the second locking hook are engaged, the two hooks are locked, and the inner stopper limiting member 16 cannot be disengaged from the locking hole 1130. As shown in FIG. 5, at this time, the first elastic wing 161 And the outer wall of the second elastic wing 162 is elastically engaged with the slot 160 of the inner plug 12, and the limiting protrusions are further disposed on the outer walls of the first elastic wing 161 and the second elastic wing 162 respectively to make the limiting convex The outer wall of the first wing 161 and the second wing 162 protrudes from the card slot 160. Preferably, a circumferential first locking hook is disposed along the mouth of the locking hole 1130, so that the second locking hook on the first elastic wing 161 and the second elastic wing 162 can be quickly matched after entering the locking hole 1130. Go to the first lock hook to lock.

When unlocking, since the first wing 161 and the second wing 162 are elastically connected, and are elastic materials themselves, they have elasticity, and the inner plug 12 is extended by opposing the first and second wings 161 and 162. The second ends c, d are such that the first elastic wing 161 and the second elastic wing 162 are brought closer together by the elastic force. At this time, the first end a of the first elastic wing 161 and the first end of the second elastic wing 162 b will be reduced in size due to relative closeness, detached from the first locking hook of the locking hole 1130, and further by pinching the second end c of the first elastic wing 161 and the second end d of the second elastic wing 162, The inner plug 12 is screwed downward, the elastic connecting member is disengaged from the locking hole 1130, and the inner plug 12 is separated from the inner layer structure 112 of the cover body 11. The rubber sleeve 13 is sleeved on the outer side of the inner plug 12, and the inner portion The plug 12 was removed together. Thus, the inner plug 12 and the rubber sleeve 13 can be removed from the cover 11 for cleaning and replacement. The elastic limiting element can control the inner plug 12 and the rubber sleeve 13 from the cover body 11 (when locked) on the one hand, and facilitate the inner plug 12 and the rubber sleeve 13 from the other side. The cover 11 is taken out for cleaning (when unlocked).

Example 2:

As shown in FIG. 8 and FIG. 9 , the inner wall of the inner plug 12 is provided with a second internal thread, and the positioning post 113 is provided with a second external thread, and the second internal thread is screwed to the second external thread, thereby The inner plug 12 is screwed onto the positioning post 113, and since the two are screwed to each other, the inner plug 12 can be moved along the positioning post 113 in the direction in which the second outer thread is disposed, so as to be close to Or away from the cover 11.

Specifically, the cover body 11 has a sealed first side and an open second side, and the positioning column 113 is disposed from the first side to the second side, that is, vertically disposed in the cover body 11. The positioning post 113 in the example is disposed at the center of the lid 11. The inner plug 12 has a ring shape, and a second internal thread is disposed in the central hole, and is screwed onto the second external thread on the surface of the positioning post 113, and is realized by screwing along the positioning post 113, that is, along the cover body 11. The inner structure 112 moves.

As shown in FIG. 9 to FIG. 11 , the elastic piece 14 is disposed on the outer side of the inner plug 12 . In the embodiment, a total of six pieces of the elastic piece 14 are evenly distributed around the outer side of the inner plug 12 . The six elastic pieces 14 are spaced apart from each other by a distance, and the bottoms of the six elastic pieces 14 are joined together and connected to the bottom of the inner plug 12, and the elastic piece 14 is aligned with the inner plug 12 in an unstressed manner. When the elastic piece 14 is subjected to a force, it will be deformed toward the biasing force, similar to the elastic fin.

The inner cover of the inner layer structure 112 is located between the inner plug 12 and the elastic piece 14. The distance between the inner plug 12 and the elastic piece 14 is appropriately larger than the thickness of the inner ring of the cup cover, so that the inner ring of the cup cover The inner plug 12 is inserted between the inner plug 12 and the elastic piece 14, but the difference is not too large, so that the whole cover is not too wide and the outer shape is not beautiful. The specific size can be determined according to the size of the cup to be sealed.

The rubber sleeve 13 is a single-sided open rubber sleeve, and the opening side is sleeved on the outer side of the inner plug 12 and the elastic piece 14. The rubber sleeve 13 is filled in the cup mouth when used in conjunction with the sealing cup to seal the cup. mouth. The rubber sleeve is made of silicone rubber, and the outer diameter is similar to the inner diameter of the cup. Therefore, after the rubber sleeve 13 is inserted into the mouth of the cup, under the rubbing of the rubber, the relative rotation between the cup and the mouth is not easily performed. The inner plug 12 and the elastic piece 14 are wrapped inside by the rubber sleeve 13, and naturally do not easily rotate under the action of static friction.

Further, the outer wall of the rubber sleeve 13 may be disposed as an irregular outer wall with irregularities to improve the sealing effect of the rubber sleeve. The inner wall of the elastic piece 14 is provided with the rib 15 protruding from the inner side of the elastic piece 14, and the inner plug 12 is moved along the connecting stud 113. The rib 15 will contact or be away from the inner ring of the cup cover, and the rib 15 will be pushed outward by the inner ring of the cup to open the outer sleeve 13 when it contacts the inner ring of the cup.

Preferably, as shown in FIG. 9 , the positioning post 113 of the cover 11 further includes a stud upper portion 1131 and a stud lower portion 1132 . The stud upper portion 1131 is located at a position of the positioning post 113 adjacent to the cover 11 . On the side, the stud lower portion 1132 is located on a side of the positioning post 113 away from the cover body 11. The second external thread on the positioning post 113 is disposed on the upper portion 1131 of the stud. Therefore, the inner plug 12 is screwed to the second external thread of the upper portion 1131 of the stud by its second internal thread. Moreover, the length of the second internal thread on the inner plug 12 is appropriately smaller than the length of the upper portion 1131 of the stud so that the inner plug 12 can move up and down along the upper portion 1131 of the stud.

The inner stopper restricting member 16 is disposed at a lower portion of the stud. The inner wall of the inner plug 12 is provided with the latching slot 160. The inner plug limiting member 16 is disposed in the latching slot 160 and can be mounted along the latching slot 161. mobile. The inner stopper restricting member 16 serves to prevent the inner plug 12 from being disengaged from the positioning post 113. The inner stopper limiting member 16 can adopt a nut.

Further, the second external thread disposed on the upper portion 1131 of the stud of the positioning post 113 is a first direction thread, and the second direction thread is disposed on the lower portion 1132 of the stud, and the first direction thread and the second direction thread are The spiral direction is opposite. In this embodiment, the column diameter of the lower portion 1132 of the stud is slightly smaller than the column diameter of the upper portion 1131 of the stud, and the first direction thread on the upper portion 1131 of the stud is a normal rotation large thread, and the second direction thread on the lower portion 1132 of the stud. To reverse the small thread.

The above two embodiments mainly provide the arrangement structure between the two inner plugs and the inner layer structure 112 of the cover body 11. The present invention is not limited to the two arrangement structures, and can be obtained under the suggestion of the present invention. Similar solutions are due to the scope of protection of this new model. In the following, the installation structure in the above embodiment 2 is taken as an example to further illustrate the use of the screwless sealing cup cover of the present invention.

8, FIG. 9 and FIG. 12, wherein FIG. 8 is a schematic view showing the assembly of the screwless sealing cup cover and the cup body 20 in the above embodiment 2, and FIG. 12 is the threadless sealing cup in the second embodiment. An exploded view of the cover and the cup 20.

First, the cover 11 of the unthreaded sealing cup cover shown in FIG. 12 is assembled into the assembled structure shown in FIG. 8;

Then, the assembled cover 11 is pressed into the cup opening 21 of the cup body 20, and the outer layer structure 111 of the cover body 11 is wrapped on the outer wall of the cup opening 21 to make the inside of the cover body 11 The layer structure 112, the inner plug 12 and the rubber sleeve 13 are inserted into the inner wall of the cup opening 21; since the rubber sleeve 13 and the inner wall of the cup opening 21 have a large static friction, the lid body 11 is rotated at this time. The rubber sleeve 13 does not rotate with the cover body 11, and the inner plug 12 and the elastic piece 14 are covered in the rubber sleeve 13, and naturally do not rotate.

At this time, the cover body 11 is rotated forward, and the cover body 11 is moved downward along the inner plug 12 by the screw connection of the connection stud 113 and the inner plug 12, when moving to the cup of the inner layer structure 112. When the inner ring of the cover contacts the rib 15 on the inner wall of the elastic piece 14, since the width of the inner ring of the cover is larger than the width of the narrow space between the rib 15 and the inner plug 12, at this time, the inside of the cover The continuation of the downward movement of the ring pushes the rib 15 and the elastic piece 14 outward from the contact portion, and the plastic sleeve 13 which is placed outside is enlarged, so that the rubber sleeve 13 is fully filled. The mouth 21 ensures that the cover 11 is not easily pulled out of the cup mouth, and has high sealing property and good safety;

On the contrary, when the cover 11 is reversed to release the cover 11, the cover 11 is slightly away from the positioning pin 113 and the inner plug 12 as the cover 11 is reversed. The inner plug 12 is until the inner ring of the inner layer structure 112 is disengaged from the rib 15 on the inner wall of the elastic piece 14, and the outward pushing of the rib 15 is released, and the elastic piece 14 is elastically restoring Returning to the initial state under the action, the rubber sleeve 13 is also returned to the initial state, as shown in FIG. 9, thereby releasing the sealing of the rubber sleeve 13 to the cup opening 21, and then the unthreaded sealing cup cover can be pulled out upward. .

In the above process of rotating the cover 11, since the lower portion of the connecting stud 113 has the inner stopper restricting member 16, it can be ensured that the inner plug never detaches from the connecting positioning post 113.

The novel non-threaded sealing cup cover can effectively avoid the hygiene problems such as bacterial growth, dust and dirt accumulation caused by inconvenient cleaning at the lid and the cup mouth; at the same time, it is convenient to use, and can effectively improve the sealing and safety of the sealing cup. .

In addition, the non-threaded sealing cup cover of the present invention further improves the arrangement of the elastic piece 14 and the rib 15 between the inner plug 12 and the inner layer structure 112 of the cover body 11 as follows:

Preferably, as shown in FIGS. 9 and 11, the rib 15 on the inner wall of the elastic piece 14 is strip-shaped and disposed along the moving direction of the inner plug 12, and, in the embodiment, the convex The rib 15 extends from the middle of the elastic piece 14 to the side of the elastic piece 14 away from the cover 11 to the bottom of the elastic piece 14. The rib 15 may also be only one bump or a laterally disposed ridge, or any other shape such as a circle, an ellipse, a triangle, or the like, and the shape and position are not limited as long as they protrude from the inner wall of the elastic piece 14 and The cover inner ring can be contacted at a certain position in the process of the inner cover 12 and the inner plug 12 moving relative to each other. At this time, under the elastic action of the elastic piece 14, the outer cover is naturally bounced outward. The rubber sleeve 13 is wrapped around the outside to achieve the effect of tightening the mouth seal.

Preferably, as shown in FIG. 9 and FIG. 10, the outer wall of the elastic piece 14 is provided with a supporting convex portion 141, and the positioning position of the supporting convex portion 141 is located at the position of the convex rib 15, when the convex portion is convex. When the rib 15 is a bump, the erecting convex portion 141 is disposed at a position corresponding to the rib 15 and is disposed on both side walls of the elastic piece 14. When the rib 15 is strip-shaped, the It is only necessary to hold the convex portion 141 to a certain portion within the length of the convex rib 15, and it is not necessary to perform full-length alignment. The function of the supporting protrusion 141 is to increase the supporting effect of the elastic piece 14 on the outer rubber sleeve 13.

Preferably, the rib 15 on the elastic piece 14 has a first end adjacent to the cover 11 and a second end away from the cover 11, and the inner cover of the cover is from the same. The first end begins to contact the rib 15. Also, from the first end, an outwardly pushing thrust is applied to the rib 15 so that the rib 15 is pushed outwardly with the elastic piece 14 to open the outer rubber sleeve 13.

Further, as shown in FIG. 9 , the first end of the rib 15 is provided with a first oblique guiding surface (not shown), and the first inclined guiding surface functions to guide the inner ring of the cup cover to gradually contact the convex portion. The rib 15 enters the narrow space between the rib 15 and the inner plug 12; and the bottom of the inner ring of the cup is provided with a second inclined surface 1121, and the inclined direction of the second inclined surface 1121 is first The inclined directions of the inclined faces are the same, and the side from the side far from the cover 11 is gradually inclined outward toward the side close to the cover 11. By providing the first oblique guiding surface and the second oblique guiding surface 1121, the inner lid 112 of the cup cover is further moved down to contact the first end of the protruding rib 15 to slowly enter the convex rib 15 along the inclined surface and the In the narrow space between the inner plugs 12, the ribs 15 and the elastic piece 14 are pushed outward with a little bit.

FIG. 13 is a cross-sectional view showing a third embodiment of a novel non-threaded sealing cup cover. In the figure, one or more tenons 210 are disposed on the inner wall of the cup opening of the cup body 20, Two paths are set in the figure. The two protrusions 210 are arranged up and down along the inner wall of the cup mouth. The distance between the adjacent tenons 210 should be controlled so that the distance between the two protrusions 210 should not be too close. The rubber sleeve 13 in the cup mouth acts as a friction reinforcement to prevent the rubber sleeve 13 from coming out of the cup mouth and to enhance the sealing property. Moreover, since the number of the ridges 210 at the cup opening is small and the spacing is large, the problem of inconvenient cleaning of the cup and accumulation of dirt is not caused. At the same time, a plurality of supporting protrusions 141 may be disposed on the outer wall of the elastic piece 14 on the inner plug 12, and the supporting protrusions 141 can not only support the reinforcing of the elastic piece 14 to the outer rubber sleeve 13 The effect is also to prevent the outer rubber sleeve 13 from coming off. The erecting convex portion 141 may be disposed at a position opposite to the convex rib 15, and one or more of the erecting convex portions 141 may be disposed above or below the position, and in FIG. 13, along the outer wall of the elastic piece 14. Two upright protrusions 141 are provided between the upper and lower sides to reinforce the joint between the elastic piece 14 and the rubber sleeve 13 to prevent the two from coming off.

In addition, the cover 11 in the embodiment of the present invention may be a transparent cover, which is made of a transparent material, so as to observe the subtle and interesting between the positioning post 113 and the inner plug 12 of the inner cover 12 through the cover 11 .
