Description

Detachable handle that attaches to the composite container}

The present invention relates to a composite container, and more particularly, to a detachable handle coupled to a composite container, in which a release prevention protrusion protruding from the container body does not protrude outward from the handle when the handle is coupled to the container body. it's about

In general, when shipping paint, etc. from the factory, the filler is put in a standardized metal container or plastic container, and then the lid is combined and shipped in a sealed state, and the user opens the lid when using the filler. When transporting or storing, the contents should not leak, and the lid can be closed again when storing or transporting after using some of the filling in the container instead of all.

Therefore, it should be easy to combine the lid of the container, and the lid should not be separated arbitrarily even if an impact is applied to the container during transportation or storage, and even if deformation occurs as the bottom of the container swells due to a rise in temperature, the deformed container does not wobble. When taking out some containers from stacked containers, the anti-leaving protrusion protruding from the main body of the container should not interfere with the anti-leaving protrusion of the adjacent container or the handle, so that the adjacent container does not move. .

Utility model registration No. 201673 "Combination structure of liquid container and synthetic resin wale", Utility model registration No. 407248 "Packing can with enhanced sealing function by double sealing", etc. Many technologies such as these have appeared, but the above technologies install a '∪'-shaped concave groove along the edge of the wat and form a '∩'-shaped projection along the edge of the lid, so that the concave groove and projection to be combined are suppressed While being fitted, both sides are configured to come into close contact with each other to form a sealing portion.

In addition, in order to minimize the deformation of the bottom of the container when the outside temperature rises, as in Patent Registration No. 2033424 "Packing Container", reinforcing ribs are formed in a circular and radial shape at the bottom of the container, and when the handle and the container body are connected, heavy weight In order to support the load, a technology of forming reinforcing protrusions, support protrusions, and departure prevention protrusions on the side of the container body has appeared.

However, technologies related to containers that have appeared so far, including the above technology, have the following problems: There is a problem in that the lid is easily detached and separated when an impact is applied during transportation or storage, so that a separate plastic member is coupled to the top of the container to prevent the lid from being separated.

Second, since the coupling part and the sealing part are not separated, and the coupling part of the lid and the warp is a structure in which the surface is in contact with each other, especially when some contents remain after use and the lid is combined and stored, the entire coupling part is in the same contact Since it is difficult to combine while doing so, there is a problem that the contents may leak while the airtightness is weakened because the entire sealing is not uniform.

Third, even if the container uses plastic, the wire and lid use a metal steel plate and apply resin to the steel plate to prevent corrosion. Since the thickness of the coated resin is thin, the applied resin is the sealing material when the wire and lid are combined. Not only can it not play a role, but it has a problem that it is vulnerable to corrosion because it is easy to scratch due to its low strength.

Fourth, when the outside temperature rises, the bottom of the container swells outward and deformation occurs. Even if a reinforcing rib is formed on the bottom surface of the container body to prevent deformation, deformation occurs such that the bottom swells and the deformed container balances. There is a problem that it cannot maintain the position and wobbles or tilts.

Fifth, when the handle is combined with the container body, in order to prevent the handle from escaping, the anti-separation protrusion protrudes from the outer circumferential surface of the container body to the outside than the handle. There is a problem that the separation prevention protrusion protruding more outward is caught on the separation prevention protrusion or the handle of the container stored adjacently, causing interference, causing the adjacent container to move along, disturbing the storage state or causing the container to fall.

The present invention has been made to solve the above problems, and an object of the present invention is to form anti-protrusion ribs at both ends of the handle so that when the handle is coupled to the container body, protrusion from the container body It is to provide a detachable handle that is coupled to a composite material container so that the formed release prevention protrusion does not protrude outward than the handle.

A detachable handle coupled to a composite material container according to the present invention is a strip shape having a certain width made of plastic, and a grip portion provided with a reinforcing portion in which a gripping portion is formed thicker than other portions; It is composed of coupling holes formed by perforation at both ends of the grip portion, and the coupling holes are formed by perforating circular shapes having a predetermined diameter at both ends of the strip of the grip portion, respectively. wealth; an insertion part which is formed on the inner side of each coupling part and is perforated and formed in the shape of a long hole whose width increases toward the inside; It is configured with hooking parts disposed on both sides of a portion where the fastening part and the insertion part are connected, the width between the hooking parts is smaller than the diameter of the fastening part, and the largest part of the insertion part is larger than the diameter of the fastening part. It is characterized by being formed.

Preferably, protrusion prevention ribs thicker than other parts are further formed on the outside of the circular shape of the coupling part and the outside of the locking part.

Preferably, when coupling the fastening part of the handle to the container body, the fastening protrusion formed on the container body is inserted into the insertion part of the handle and the grip part is pulled so that the fastening protrusion is fastened to the fastening part.

Preferably, the container body has a cylindrical shape with a closed bottom surface, and on an outer surface near the upper end of the cylindrical shape, binding protrusions having a predetermined diameter are formed protruding outward at opposite positions, respectively, and each binding protrusion is formed. Separation preventing protrusions having a larger diameter than the binding protrusions are formed at the ends of the protrusions, and the outermost surface of each anti-leaving protrusion is formed to be flat, so that the detachable handle is fastened to the binding protrusions.

In the detachable handle coupled to the composite container according to the present invention, since the protrusion prevention ribs are formed at both ends of the handle thicker than other parts, when the handle is coupled to the container body, the separation prevention protrusion protruding from the container body is formed on the handle. Since it does not protrude further outward, when taking out or moving some containers from among the stored containers, the anti-leaving protrusion protruding outward from the handle does not get caught or interfere with the anti-leaving protrusion of the adjacent container or the handle. , the storage conditions of adjacent containers will not be disturbed or tipped over.

The technical characteristics of the composite container according to the present invention are that the corrosion resistance, chemical resistance, and preservation of contents are significantly improved by using laminated steel plates for the container's warp and lid, and by separating the joint and sealing portion of the warp and lid, Even if an impact is applied, the lid is not easily separated and airtightness is significantly improved, and by forming inner ribs with a certain size and height on the bottom of the container, the deformed container does not wobble or tilt even when the temperature rises. The point is that by forming a protrusion prevention rib on the handle coupled to the container body, the separation prevention protrusion formed on the container body does not protrude outward from the handle.

The container body 21 of the container 20 has a cylindrical shape with a closed bottom surface, which is made of plastic (synthetic resin), and a wate 22 integrally coupled to the top of the container body and a lid coupled to the wate 22 (23) uses a laminated steel plate made by laminating a film of PE, PT or PET material on a stone plate. In this way, since the material of the container body 21 and the material of the warp 22 and the lid 23 are different from each other, it is named 'composite material container'. Since the laminated steel sheet is used for the wat 22 and the lid 23, there is an advantage in that the corrosion resistance and chemical resistance of the container are excellent. In addition, in the prior art, resin was applied to a metal plate and used, but when a laminated steel plate is used as in the present invention, scratches do not occur during handling of the container because the thickness of the laminated film is much thicker than the thickness to which the resin is applied, and the warp and lid When combined, the laminated film serves as a sealing material, so it has the advantage of improving the airtightness of the container and preserving the contents.

Wate 20 is composed of a seaming portion 221, a coupling groove portion 222, and a winding portion 223. The seaming part 221 is a part formed by seaming the upper end of the container body 21 and the outer end of the warp 22, and the seam of the warp made of laminating steel plate to the container body 21 made of plastic Since the end of the ming part 221 is embedded and integrally coupled, it is not separated under any circumstances and leakage through the seaming part 221 is fundamentally blocked. The coupling groove 222 is formed on the inside of the seaming part 221, is spaced apart from the seaming part 221 at a predetermined interval, is formed to have a lower height than the seaming part inside the seaming part, and is formed in a 'c' shape that is open upwards, that is, a recessed part. (concave) is formed.

The winding portion 223 is configured to be wound at a predetermined interval from the upper end of the sidewall located inside the coupling groove 222 toward the inside of the sidewall. The winding part 223 is formed by outer winding, and since the position of the winding part 223 is formed to be located at a higher position than the upper end of the coupling groove 222, it is located inside from the coupling groove 222. Since the winding part 223 is formed in an upwardly inclined direction from the upper end of the side wall, the winding part 223 applies the force applied while pressing the lid 23 when coupling the lid 23 to the warp 22 It will be able to withstand without sinking. In addition, since the winding portion 223 is formed by outer winding, the cutting surface generated when cutting the laminated steel sheet is located outside the sealing portion of the lid 23 and the wale 22, so that the container body 20 Corrosion of the cut surface can be fundamentally prevented because the stored contents do not come into contact with the cut surface, which is the end of the rolled steel sheet.

The lid 23 is manufactured by bending a plate-shaped laminated steel sheet, and includes coupling protrusions 231, rims 232, and bent protrusions 233. The coupling protrusion 231 is a downwardly bent portion and is formed in a shape corresponding to the coupling groove 222. The coupling protrusion 231 is inserted into the coupling groove 222 of the wate to be coupled. When the lid 23 is coupled to the wat 22, the outer surfaces of both side walls of the coupling protrusion 231 are closely inserted into the inner surfaces of both side walls of the coupling groove 222, and the lid 23 and the wate 22 To form a coupling portion, the gap between both side walls of the coupling protrusion 231 should be formed slightly larger than the interval between both side walls of the coupling groove 222 so that the lid 23 and the wate 22 are in close contact at the coupling portion can be combined.

The rim 232 is formed by winding outward from the upper end of the side wall located outside the coupling protrusion 231, and when the lid 23 is coupled to the wale 22, the coupling groove formed on the wale 22 ( 222) and the lower end of the rim 232 formed on the lid 23, a certain gap d must be formed to open the lid 23. A tool can be easily opened by inserting it into the gap (d). Here, the height of both side walls of the coupling protrusion 231 must be formed higher than the height of both side walls of the coupling groove 222 so that a gap d can be formed between the upper end of the side wall of the coupling groove 222 and the lower end of the rim 232. . In addition, when the container 20 is loaded, the outer rib 24 protruding from the lower end of the container placed on the top is inserted into the space formed between the outer circumferential surface of the rim 232 and the seaming portion 221 of the wate to stabilize the container. can be loaded with

The bent protrusion 233 is bent horizontally from the upper end of the side wall located inside the coupling protrusion 231 toward the inside and then bent downward again to form a 'c' shape open downward, the lid ( When 23) is coupled to the wale 22, the outer circumferential surface located at the innermost side of the winding portion 223 formed on the wale 22 adheres to the inner wall 233a of the bent protrusion 233 formed on the lid 23. to form a sealing portion, and in the sealing portion, the innermost outer circumferential surface of the winding portion 223 is in close contact with the wall surface of the inner wall 233a, and the surface and the line meet to form a sealing portion (sealing line), and the lid 23 ) and the film laminated to the warp 22 serve as a sealing material, thereby significantly improving airtightness.

In this way, the coupling structure of the lid 23 and the wire 22 is coupled by closely inserting the outer surfaces of both side walls of the coupling protrusion 231 into the inner surfaces of both side walls of the coupling groove 222, and the lid 23 and the wire 22 ) Forms a coupling portion, and the outer circumferential surface located on the innermost side of the winding portion 223 formed on the wale 22 is in close contact with the inner wall 233a of the bent protrusion 233 formed on the lid 23 to form a sealing portion (sealing line), the coupling part and the sealing part (sealing line) are distributed in different positions and formed in double contact, so it is easy to combine the lid 23 with the wate 22, and transport or storage of the container Even if shock or vibration is applied to the container during the lid 23 is not easily separated from the warp 22. In addition, since the contents stored in the container body 21 cannot flow out to the outside of the sealing part (sealing line), corrosion of the cut surface of the laminated steel sheet is prevented, and since the contents do not flow into the coupling part at all, a strong connection can be maintained.

Since the composite material container is configured such that the upper part of the container body 21 made of plastic is tightly coupled to the warp 22 and the lid 23 made of metal to maintain airtightness, when the outside temperature rises, the stored container As is expanded, deflection occurs as the bottom surface of the container body 21 made of plastic forms a convex outward arc. In this way, when the bottom surface is swollen and the bottom surface sags, the container body cannot maintain a horizontal state and tilts to the side while waddling, making it impossible to maintain a stable posture. will roll down to the floor. In order to prevent such a phenomenon, generally, a rib is formed on the bottom surface of the container body and circular and/or radial reinforcing ribs are formed on the inside thereof, but the container body is in a horizontal state when the outside temperature rises. The problem of being unable to maintain a stable posture due to waddling and tilting to the side still remains.

In order to solve this problem, one of the important technical features of the composite material container according to the present invention is that the circular outer rib 24 and the inner rib 25 are formed on the bottom surface of the container body 21 according to certain conditions. One. That is, when the outside temperature rises and the bottom surface of the container body 21 swells outward and sags downward, the outer rib 24 is separated from the base surface on which the container is placed and floats in the air. In this state, the inner rib 25 supports the container body 21 on the base surface, so that the container body 21 maintains a horizontal state while preventing the container from wobbling or tilting to maintain a stable posture. It becomes (see FIG. 5).

When the bottom surface of the container body 21 is convexly deformed outwardly and inflated to form an arc shape, the size of the radius R of the arc shape when the bottom surface sags to the maximum is It is designed to be twice the size of the outer diameter D of the container body 21.

The outer rib 24 has a predetermined height (H) along the edge of the bottom surface of the container body 21 and is formed in a circular shape protruding outward from the bottom surface. However, when the bottom surface of the container body 21 is deformed and swells outward convexly to form an arc shape, the maximum deflection of the deformed arc shape bottom surface is greater than the height H of the outer rib 24. Therefore, since the bottom surface of the container body 21 formed in an arc shape comes into contact with the base surface on which the container body is placed, a phenomenon in which the container body wobbles and tilts occurs. Therefore, by forming an inner rib 25 that meets certain conditions inside the outer rib 24, the arc-shaped bottom surface does not touch the base surface, but instead the inner rib 25 touches the base surface on which the container body is placed. By supporting the container body, it is possible to maintain a stable posture (see Fig. 5 (b)).

The inner rib 25 is spaced apart from the outer rib 24 at a predetermined interval and is formed in a circular shape protruding outward from the bottom surface with a predetermined height (h) and an outer diameter (d) on the inside of the outer rib 24, the container body Even if deformation occurs on the bottom surface of the container body in order to maintain a stable posture in a horizontal state, the size of the outer diameter (d) of the inner rib 25 is 50 to 75% of the size of the outer diameter (D) of the container body 21 should be formed as If the size of the outer diameter (d) of the inner rib 25 is smaller than 50% or larger than 75% of the outer diameter (D) of the container body, when the maximum deflection occurs on the bottom surface of the container body, the circular arc shape of the container body Since only the bottom surface touches the base surface and the inner rib 25 is spaced apart from the base surface and is in a state of floating in the air, a problem arises in that the container body does not maintain a horizontal state and is tilted while waddling.

In addition, the height (h) of the inner rib 25 is formed to be smaller than or equal to the height (H) of the outer rib, and the maximum deflection amount and It should be equal or larger. If the height (h) of the inner rib 25 is formed to be larger than the height (H) of the outer rib 24, only the inner rib 25 touches the base surface and the outer rib 24 does not deform the container body. There is a problem that it is always separated from the background surface and floats in the air. On the other hand, if the height (h) of the inner rib 25 is formed smaller than the maximum deflection of the bottom surface of the container body, only the bottom surface of the container body formed in an arc shape touches the base surface when the maximum deflection occurs on the bottom surface of the container body, Since the ribs 25 are spaced apart from the base surface and float in the air, a problem arises in that the container body does not maintain a horizontal state and is tilted while waddling.

As shown in FIG. 6, when the containers are stacked and deformation does not occur at room temperature, the outer rib 24 of the container body placed on the upper side is connected to the seaming portion 221 of the warp of the lower container and the coupling groove 222 ) Placed on the connecting part between the upper ends, the inner rib 25 floats on the inner bottom surface of the circular shape formed by the bent protrusion 233 in the lid 23 as the circumference of the outer rib 24 Due to the support, it is possible to maintain a stable state (see ⒜ of FIG. 6).

On the other hand, when the containers are stacked and deformation occurs at high temperature, the bottom surface of the container body swells outward to form an arc shape, and the portion where the maximum deflection occurs on the bottom surface is the circumference of the bent protrusion 233 in the lid 23. The inner rib 25 touches the inner bottom surface of the circular shape formed by contacting or slightly floating, and the inner rib 25 touches the inner bottom surface of the circular shape formed by the bent protrusion 233 in the lid 23 as a circumference, support to keep it stable. At this time, the outer rib 24 of the upper container body is spaced apart from the portion connecting the upper end of the coupling groove 222 and the seaming portion 221 of the wate of the lower container and is in a floating state (b in FIG. 6 Reference).

The composite material container according to the present invention may have a detachable handle 10 for convenience in handling and transporting the container. In order to detach the handle 10 from the container body 21, the container body 21 must have a locking projection 211 and a separation prevention projection 212 formed thereon. The container body 21 has a cylindrical shape with a closed bottom surface, and on the outer surface near the upper end of the cylindrical shape, binding protrusions 211 having a predetermined diameter are formed to protrude outward at positions facing each other, respectively, At the end of each coupling protrusion 211, a separation preventing protrusion 212 having a larger diameter than the coupling protrusion 211 is formed, and the outermost surface exposed to the outside of each separation preventing protrusion 212 is flat. It is formed so that the detachable handle 10 is fastened to the fastening protrusion 211.

The handle 10 detachably coupled to the container body of the composite container according to the present invention includes a grip part 11 and coupling holes 12 drilled at both ends of the grip part 11. The grip part 11 is made of plastic and has a band shape with a certain width, and is composed of a reinforcement part 111 in which a part to be gripped by the user is thicker than other parts, and the reinforcement part 111 is provided. Because of this, the handle 10 is not only strong, but also has a good grip, and even if the user holds the container containing the contents for a long time, the hand does not hurt. In addition, coupling holes 12 are perforated at both ends of the grip portion 11, respectively.

The coupling hole 12 includes a coupling portion 122 coupled to the coupling protrusion 211 formed on the container body, an insertion portion 121 located inside the coupling portion 122, and the insertion portion 121 and the coupling portion. It is configured with a hooking portion 123 disposed between (122). The binding part 122 is formed at both ends of the strip shape of the grip part 11, and is perforated in a circular shape having a certain diameter. It is preferable to form slightly larger than the diameter of (211).

The insertion part 121 is formed to be positioned on the inner side of the fastening part 122 and formed by being perforated in the shape of a long hole whose width increases toward the inside. The part with the largest width in the insertion part 121 is It is formed larger than the diameter of the circular shape constituting the fastening portion 122 . In addition, the hooking part 123 is configured to be disposed on both sides of a portion where the fastening part 122 and the insertion part 121 are connected, and the width between the two hooking parts 123 is smaller than the diameter of the fastening part 122. It must be formed so that the coupled coupling part 122 coupled to the coupling protrusion 211 does not easily come off (see FIG. 3). If the width between the hooking parts 123 is larger than the diameter of the fastening part 122, a problem arises in that the handle coupled to the container body is easily separated.

When fastening the handle 10 to the container body 21, insert the fastening protrusion 211 formed on the container body into the insertion portion 121 of the handle, and then pull the grip portion 11 of the band shape to the container body ( After the fastening protrusion 211 protruding from 21) passes through the hooking part 123 and is fastened to the fastening part 122, the width between the two hooking parts 123 is smaller than the diameter of the fastening part 122. Because of this, the fastening protrusion 211 does not fall out of the fastening part 122 . In addition, since the portion having the largest width in the insertion portion 121 is formed larger than the diameter of the coupling portion 122, it is convenient when the coupling protrusion 211 is inserted into the coupling hole 12 and fastened.

In the present invention, one of the technical characteristics of the composite material container 20 to which the detachable handle 10 is coupled is to form the anti-protrusion rib 13. The anti-protrusion rib 13 is a part formed thicker than other parts on the outside of the circular outer portion of the fastening portion 122 and the outer side of the locking portion 123. The thickness of the anti-protrusion rib 13 is the thickness of the anti-separation protrusion 212. It is preferable to form as follows (see FIG. 3). Binding protrusions 211 protrude from the upper portion of the container body at positions facing each other, and after fastening the handle 10 to the binding projection 211 of the container body 21, the binding protrusions 211 In order to prevent the handle 10 from escaping, a separation prevention protrusion 212 having a diameter greater than the diameter of the binding protrusion 211 is formed at the end of the binding protrusion 211 .

However, if the anti-protrusion rib 13 is not formed on the handle, after the handle is fastened to the locking protrusion 211, the anti-release protrusion 212 protrudes outward more than the handle. ) protrudes outward from the handle 10, so when taking out or moving some containers from stacked storage containers, the release prevention projection 212 protruding outward from the handle is adjacent to the separation prevention projection 212 of the container stored ) or being caught on the handle, causing interference, causing adjacent containers to move along, resulting in a problem of disturbing the storage state or causing the container to fall. However, in the present invention, since the anti-protrusion rib 13 is formed around the fastening part 122 of the handle, the anti-protrusion rib 13 surrounds the outer side of the anti-detachment protrusion 212, and the anti-detachment protrusion 212 Since ) does not protrude outward from the handle and the outermost surface exposed to the outside of the anti-protrusion rib 13 and the anti-departure protrusion 212 form the same surface, the anti-departure protrusion 212 is the anti-departure protrusion of another container 212) or it does not interfere with being caught on the handle (see FIGS. 2 and 3).

The above description is illustrative of the present invention, and the embodiments disclosed in the specification are not intended to limit the technical idea of the present invention, but are for explanation. Various modifications and variations will be possible without departing from the technical idea of Therefore, the protection scope of the present invention should be construed by the matters described in the claims, and technical matters within the scope equivalent thereto should be construed as being included in the scope of the present invention.
