Description

Sanitary cover with can lid open function {Sanitary cover with can lid open function}

The present invention relates to a sanitary cover having an opening function for a can lid, and more specifically, to an invention in which the upper lid plate of a can container is wrapped by a sanitary cover to hygienically store the can, and the beverage can be easily drunk by opening the lid plate with an action of separating the sanitary cover to drink the beverage.

In general, cans of alcohol and various beverages have been widely used in daily life due to their convenience in storage and use.

However, since the top lid of conventional cans is always exposed to the outside, dust and other foreign substances accumulate when stored for a long time, and users have to wipe the foreign substances off with their hands or with tissue paper before drinking the beverage from the can, which poses a sanitary problem.

Accordingly, as a method to improve the above-mentioned problem, a sanitary cover made of synthetic resin material is provided to be assembled on the top of the can, and the sanitary cover is placed over the lid plate on the top of the can to prevent external contaminants from entering in advance.

However, the sanitary cover simply has a circular shape and is assembled to cover the top of the can container, so after removing the sanitary cover, a step of lifting the can hook again to open the cap plate is still required in order for the user to drink the beverage, which causes inconvenience to the user.

In addition, since the sanitary cover is assembled by hanging on the lid plate of the can container, there are still problems in use, such as the sanitary cover being easily separated due to movement or impact, or the sanitary cover being forcibly fitted on the lid plate, making it difficult for the user to separate the sanitary cover.

Republic of Korea Utility Model Registration No. 20-0418272. Protective cover for can lid (Registration date: June 1, 2006)

In order to solve the problems of the prior art as described above, the present invention provides a sanitary cover having an opening function of a can lid, which is configured such that the can ring is pulled and the cap plate is folded when the sanitary cover assembled to the upper part of the can container is separated, thereby allowing the user to drink the beverage right away.

In addition, the present invention aims to provide a sanitary cover having an opening function of a can lid, in which a cover projection of the sanitary cover is fitted into a seaming groove of a can container so that the sanitary cover is not easily separated during storage and transportation, and a gap with the lid plate is maintained so as to prevent damage to a ring fitting assembled to a can ring.

To solve such technical problems, the present invention,

In a sanitary cover (30) assembled to a lid plate (11) of a can container (10) to prevent the inflow of external foreign substances;

The above sanitary cover (30) is provided with a cover projection (32a) that is assembled by being hooked onto a seaming processing protrusion (12) formed on the outer circumference of the can container (10), and a ring fitting hole (33) is formed protruding from the center toward the outside on the bottom surface of the cover portion (31), so that the can container (10) and the sanitary cover (30) are assembled by hooking the ring fitting hole (33) from the inside of the ring hole (14a) of the can hook (14) to the outer bottom surface of the can hook (14).

In addition, the sanitary cover (30) may be configured such that a pull handle (36) is formed to extend in the horizontal direction of the outer circumference (32) along the same line as the ring fitting (33), so that when the pull handle (36) is pulled, the can hook (14) caught on the inside of the ring fitting (33) is lifted, and a stacked groove (31a) in which the bottom surface of another can container (10) is received may be formed on the upper surface of the cover portion (31).

In addition, the ring fitting (33) of the sanitary cover (30) may be provided as a flat plate and may be provided with an elastic part (33a) bent downward at the tip, so that the elastic part (33a) is supported by the lid plate (11) of the can container (10) and may be configured to support the lower surface of the can hook (14) fitted inside the ring fitting (33).

In addition, the ring fitting (33) of the sanitary cover (30) can be configured by forming the tip of a flat plate into a spire shape, while forming an inclined portion (33b) on the upper surface of the spire shape, so that the inclined portion (33b) is guided and inserted between the ring holes (14a) of the can hook (14) at the top of the lid plate (11) of the can container (10).

In addition, the ring fitting (33) of the sanitary cover (30) can be configured such that at least one downwardly protruding reinforcing portion (33c) is formed in the longitudinal direction on a flat plate.

In addition, the ring fitting (33) of the sanitary cover (30) is formed to have a bent portion (35) in the shape of a lying down "S", so that the bent support surface (35a) is supported on the lid plate (11) of the can container (10), and the fitting end (35b) is fitted into the ring hole (14a) of the can hook (14), so that the can hook (14) can be assembled so that it is positioned in the ring fitting space (35c) on the inside.

In addition, in the cover part (31) of the sanitary cover (30), a folding line (37) is further formed vertically with the can hook (14) centered on the rivet (13) that fixes the can hook (14) to the lid plate (11), so that it can be configured to be divided into a first separation part (38a) including the can hook (14) and a second separation part (38b).

In addition, the outer circumference (32) of the sanitary cover (30) may further include a cover portion (34) extending downwards and covering the upper circumference including the seaming processing ridge (12) of the can container (10), and a cutting line (34a) that is distinct from the outer circumference (32) and the pull handle (36) may be further formed so that the cover portion (34) may be cut and separated along the cutting line (34a).

According to this invention, the sanitary cover assembled on the top of the can container is separated while simultaneously lifting the can hook to fold the cap plate, thereby improving the convenience of use by allowing the user to drink the beverage right away.

In addition, since the cover projection of the sanitary cover is fitted into the seam processing groove of the can container, the sanitary cover is not easily separated during storage and transportation, and since the cover projection is fitted into and fixed to the outer diameter of the can container, the method of inserting a ring fitting between the lid plate and the can hook improves work convenience and marketability, thereby also increasing product competitiveness.

The present invention can be modified in various ways and can take various forms, and the embodiments are described in detail in the text. However, this is not intended to limit the present invention to a specific disclosed form, and it should be understood that it includes all modifications, equivalents, or substitutes included in the spirit and technical scope of the present invention.

Hereinafter, the features of a sanitary cover having an opening function of a can lid according to the present invention will be understood through embodiments described in detail with reference to the attached drawings.

First, the sanitary cover (30) having the open function of the can lid described in the present invention has a shape in which the lower part is opened so that a thin cover part (31) made of synthetic resin can cover the lid plate (11) of the can container (10), as shown in FIGS. 1 to 4, and a cover projection (32a) that is caught on a seaming processing step (12) provided on the outer periphery of the can container (10) is folded and integrally formed on the outer surface of the cover part (31).

The can container (10) is sealed at the top with a lid plate (11) to prevent outside air from flowing into the cylindrical can body with an open top. The edge of the opening of the can body and the edge of the lid plate (11) are wrapped together and pressed, and the work of wrapping the lid plate (11) around the can body and pressing it in this way is generally called a can seaming work.

Here, the can seaming operation will be briefly explained. As the seaming means, which is composed of a seaming chuck and a seaming roll, descends, the seaming chuck fixes and rotates the can body and the lid plate, while the seaming roll presses the edges of the can body and the lid plate together to seal the can. Through the seaming operation, a concave seaming processing protrusion (12) is formed on the outer surface of the can container (10).

In addition, the lid plate (11) is configured such that a can hook (14) is fixed using a rivet (13) and a cap plate (15) is bent downward along a fine cut groove formed in the lid plate by a load that pulls the can hook (14) upward, thereby allowing the beverage stored in the can to be discharged. This configuration can be applied in various ways according to the needs of those skilled in the art with respect to the configuration of the lid plate (11), and is not limited to a specific one.

At this time, since it is already a common configuration to form the can hook (14) with a ring hole (14a) having a ring shape such as a circle or an oval on the inside, a detailed description will be omitted.

The sanitary cover (30) of the present invention is configured such that a cover part (31) is positioned on the upper part of the lid plate (11) of the can container (10), and a cover projection (32a) formed by folding on the inner side of the cover part (34) is fitted into a seaming processing protrusion (12) formed on the outer circumference of the can container (10) to prevent external foreign substances from entering the lid plate (11), and at the same time, a ring fitting hole (33) is provided on the lower surface of the cover part (31) so that the ring hole (14a) of the can hook (14) is fitted from the inner side to the outer lower surface of the can hook (14), thereby assembling the can container (10) and the sanitary cover (30).

The above-mentioned ring fitting (33) is formed in an outward direction from the center of the bottom surface of the cover part (31), and allows the can hook (14) to be inserted into the inner groove of the bottom surface, so that when the ring fitting (33) is pulled, the can hook (14) is also pulled.

In addition, the cover part (31) of the sanitary cover (30) is formed transparently or semi-transparently so that the user can recognize the inner lid plate (11) and the can hook (14) inserted into the hook fitting (33), and check for contamination and incorrect assembly.

In addition, the outer circumference of the cover part (31) is provided with an outer circumference part (32) that is bent downwards to wrap around the outer circumference of the upper part of the can container (10), and a cover projection (32a) that protrudes inwardly of the outer circumference part (32) is further provided, so that the cover projection (32a) is caught in the groove of the seaming processing jaw (12) and the sanitary cover (30) is assembled to the upper part of the can container (10).

At this time, the outer peripheral portion (32) is formed to be inclined in the outward direction from the lower end of the cover projection (32a), so that the cover projection (32a) of the outer peripheral portion (32) can be inserted into the seaming processing protrusion (12) more easily when assembling the sanitary cover (30) to the upper part of the lid plate (11) of the can container (10).

Here, the sanitary cover (30) is configured so that a pull handle (36) is extended in the horizontal direction of the outer circumference (32) along the same line as the ring fitting (33), so that when the pull handle (36) is pulled, the can hook (14) caught on the inside of the ring fitting (33) is lifted, thereby allowing the user to more easily pull the can hook (14) and flip the cap plate (15), thereby allowing the user to more easily consume the contents of the can container (10).

In addition, a concave stacking groove (31a) is further formed on the upper surface of the cover part (31) so that the bottom surface of another can container (10) can be stacked and stored, thereby improving the convenience of storing the can container (10).

Here, the ring fitting (33) of the sanitary cover (30) is provided as a flat plate and is formed to have a spire shape so that the tip can be easily inserted between the lid plate (11) of the can container (10) and the ring fitting (33), so that the can hook (14) is positioned inside the ring fitting (33).

In addition, the ring fitting (33) is provided with an elastic part (33a) bent downward at the plate tip, so that the elastic part (33a) is supported by the lid plate (11) of the can container (10) and supports the lower surface of the can hook (14) fitted inside the ring fitting (33), thereby forming a gap equal to the height of the lid plate (11) and the elastic part (33a), so that the ring fitting (33) can then pull the can hook (14) with less force.

And, as an embodiment of the present invention, as shown in FIG. 5, the ring fitting hole (33) of the sanitary cover (30) is formed with an "S" shaped curved portion (35) that is laid down on the bottom surface of the cover portion (31), so that the curved support surface (35a) is supported on the lid plate (11) of the can container (10), and the fitting end portion (35b) on one side is fitted into the ring hole (14a) of the can hook (14), and the can hook (14) is assembled so that it is positioned in the inner ring fitting space (35c) where the curved support surface (35a) is formed.

Accordingly, the detachment of the can hook (14) located in the ring-fitting space (35c) of the above-mentioned bent portion (35) is prevented, and the lid plate (11) and the can hook (14) are configured to have a certain gap through the bent support surface (35a).

In addition, as another embodiment of the present invention, as shown in FIG. 6, the ring fitting (33) of the sanitary cover (30) is formed by forming the tip of a flat plate into a spire shape, and forming an inclined portion (33b) on the upper surface of the spire shape, so that the inclined portion (33b) is guided and inserted between the ring holes (14a) of the can hook (14) at the upper part of the lid plate (11) of the can container (10). This is also included in the present invention.

In addition, the ring fitting (33) of the sanitary cover (30) is configured so that at least one downwardly protruding reinforcing portion (33c) is formed in the longitudinal direction of the ring fitting portion (33) on a flat plate, thereby reinforcing the rigidity of the ring fitting portion (33), and at the same time, the bottom surface of the reinforcing portion (33c) is supported by the lid plate (11), so that the lid plate (11) and the can hook (14) have a certain gap.

In addition, the reinforcing part (33c) of the above-mentioned ring-fitting hole (33) is formed to have a curved shape to match the shape of the can hook (14), so that the can hook (14) is inserted into the reinforcing part (33c) and secured, so that when the above-mentioned sanitary cover (30) is lifted, the can hook (14) is not detached from the ring-fitting hole (33) but is pulled together so that the stopper plate (15) can be folded.

In addition, the sanitary cover (30) of the present invention can be reassembled on the upper part of the can (10) even after the cap plate (15) of the can (10) is folded, thereby preventing foreign substances from entering the interior of the can (10) with remaining contents, and preventing the contents from leaking out.

Hereinafter, the process of reassembling the sanitary cover (30) to the can container (10) as described above will be described. As shown in (a) of FIG. 7, the can hook (14) is positioned so as to be inclined upward, the sanitary cover (30) is positioned on the upper side, and as shown in (b) of FIG. 7, the hook fitting hole (33) is moved so as to be inserted into the hook hole (14a) of the can hook (14), and then one side of the sanitary cover (30) is pressed toward the seaming projection (12) of the can container (10) so that the cover projection (32a) of the outer circumference (32) is fitted and assembled, and then, as shown in (c) of FIG. 7, the other side of the sanitary cover (30) is pressed so that the cover projection (32a) of the outer circumference (32) is caught on the seaming projection (12) so that the sanitary cover is reassembled.

In addition, as an example of the use of the present invention, as shown in FIG. 8, the cover part (31) of the sanitary cover (30) is configured to further have a folding line (37) having a 'v' groove shape formed on the upper surface in a direction perpendicular to the pull handle (36), so that one side where the pull handle (36) is located can be divided into a primary separation part (38a), and the other side can be divided into a secondary separation part (38b).

That is, the cover part (31) further forms a folding line (37) vertically with the can hook (14) centered on the rivet (13) that fixes the can hook (14) to the lid plate (11), so that when the user pulls the pull handle (36), the primary separation part (38a) including the can hook (14) is pulled first, causing the cap plate (15) to fold, and then when the pull handle (36) is pulled once more, the secondary separation part (38b) is pulled, causing the sanitary cover (30) to be separated from the can container (10), allowing the user to consume the contents of the can container (10).

In addition, in the process of reassembling the cover part (31) to the can container (10), the present invention also includes inserting the ring fitting (33) included in the first separation part (38a) into the can ring (14) while folded along the folding line (37), then unfolding the second separation part (38b), and then simply reassembling the outer circumference part (32) to the seaming processing jaw (12).

And, as another embodiment of the present invention, as shown in FIG. 9, it is preferable that the outer peripheral portion (32) of the sanitary cover (30) further includes a cover portion (34) that is closely fixed to the upper peripheral surface including the seaming processing jaw (12) of the can container (10).

The above cover part (34) is formed to extend downward further along the outer circumferential surface of the can (10) from the lower end of the cover projection (32a) so as to be in close contact with the upper circumferential surface of the can (10), thereby preventing the sanitary cover (30) from being arbitrarily separated from the can (10) and also preventing the contents inside the can (10) from leaking.

In addition, the cover part (34) is provided to extend from the outer circumference part (32) and wrap around the upper outer diameter part of the can container (10), thereby preventing external contaminants from being applied to the can container and preventing damage to the painted surface and coating surface, etc., due to impact between the can containers during storage and movement.

In addition, the cover part (34) is further formed with a cutting line (34a) that is distinguished from the outer circumference (32) and the pull handle (36) of the sanitary cover (30), so that when a user wants to consume a beverage, he/she first cuts and separates the cover part (34) along the cutting line (34a), and then pulls the pull handle (36) to fold the cap plate (15) so that the beverage can be consumed. This is also included in the present invention.

As described above, the above-described embodiments have described the most preferred examples of the present invention, but they are not limited to the above-described embodiments, and it is obvious to those skilled in the art that various modifications are possible within a scope that does not depart from the technical idea of the present invention.
