Description

[0001] CONSTRUCTIVE ARRANGEMENT IN A COLLAPSIBLE DRUM WITH ANCHORING

[0002] Introduction

[0003]

[0001] This Utility Model patent application refers to a novel “CONSTRUCTIVE ARRANGEMENT IN A COLLAPSIBLE DRUM WITH ANCHORING”, comprising a packaging formed by a collapsible body of cardboard or cellular plastic or even raffia with the insertion of cellular plastic plates, equipped with creases, with fastening straps with locks and rigid plastic lids, equipped with a nozzle for filling and emptying products, also equipped with guides for anchoring, resulting in a collapsible drum with a capacity to transport from 100 to 250 liters, bringing economic, logistical, operational and environmental advantages in relation to known models.

[0004] Field of application

[0005]

[0002] Innovation is applied in the logistics segment for the storage and transport of granulated, liquid and pasty products.

[0006] Persuasion

[0007]

[0003] It is known to those skilled in the art that the chemical and food industries make extensive use of rigid drums, made of metal, plastic, cardboard, or even collapsible drums, mainly for the transport of liquid and pasty products.

[0008]

[0004] Thus, the market provides cylindrical and rigid packaging, in the above materials, cellulose cardboard, or metal or plastic, also popularly known as barrels, drums and jerrycans, respectively, in addition to semi-flexible packaging made of cardboard or cellular plastic, with or without a rigid plastic lid and flexible raffia packaging.

[0009]

[0005] Semi-flexible and foldable cardboard or honeycomb plastic packaging has the disadvantage of having a flat and fragile bottom lid, which makes it difficult to tilt the packaging and move it individually directly on the floor or on rollers, requiring the use of pallets or sheets for support and carts or forklifts for handling.

[0010]

[0006] Semi-flexible and foldable cardboard or honeycomb plastic packaging with a rigid plastic bottom lid has the disadvantage that its bottom lid does not facilitate reverse logistics and reuse, as they are tall, take up a lot of space, and increase return freight costs. Another drawback is that they do not have a device for anchoring straps / lashing tapes, thus making the operation of threading the strapping tapes, which are welded together to secure the assembly by friction and thermal means or by metal staples, and in both cases, these tapes are broken after use and cannot be reused.

[0011]

[0007] Flexible raffia packaging has the disadvantage of not having a rigid top and bottom lid, as well as a body with rigid walls, which causes a lack of stability in handling, transport and stacking, especially of liquid and pasty products.

[0012]

[0008] Metal drums, plastic containers and barrels are rigid packaging that take up more space during transport, especially when empty.

[0013]

[0009] Collapsible drums comprise a transport packaging structure that generally has a cylindrical or octagonal shape, featuring a body, a top lid, and a bottom lid. Collapsible drums are intended for filling, storing, manually or mechanically handling, and transporting granulated, liquid, and pasty materials, preferably in volumes ranging from 100 liters to 250 liters. They have the disadvantage of requiring a long assembly time, and even more time is spent closing them with strapping tapes, which are necessary for safe handling and transport after filling and during use.

[0014]

[0010] In this context, new technologies that enable the elimination of strapping tapes, speed up and make the assembly of drums more practical, and optimize reverse logistics are welcome in the segment in question.

[0015] State of the art

[0011] The current state of the art includes some patent documents that deal with collapsible drums, such as document PI 0505874-0 entitled “CONSTRUCTIVE ARRANGEMENT IN DRUM CONTAINER” - comprising a lid positioned at the top and bottom of a drum container, said lid following the shape of the drum container body characterized by the fact that the lid has a surface with a circular projection and the octagonal projection of a flange that surrounds the edge of the drum container body, said surface having a central recess and concentric channels to accommodate the tie straps, said concentric channels starting from the central recess and having recesses and ribbed grooves arranged between the channels, with said lid including edges of the upper surface with a chamfered region; to feature recesses arranged on the lid flange that coincide with the through holes arranged on the surface of the drum container body.

[0016]

[0012] The drum container described in the document above has channels in the lids for securing the lids to the body, but there is no option for anchoring them to the body itself. Furthermore, the tie-down straps used are not reusable because they lack any mechanical coupling system. Another drawback is that the previous design does not have an opening / nozzle for filling when already tied, which creates problems such as increased safety risks during filling and the impossibility of pre-tying the containers before filling, making the operation more time-consuming.

[0017]

[0013] Document BR 212016015073-8 entitled “CONSTRUCTIVE ARRANGEMENT IN DRUM CONTAINER” - comprises a cardboard lid positioned on top and a plastic lid positioned on the base of the drum container body, said lid following the shape of the drum container body, characterized by the fact that the lid has an orthogonal projection with a flap equipped with carrying handles arranged in an alternating manner, describing between the flaps grooves for accommodating tie straps, which have a positive projection facing the lower portion of the cardboard lid that coincide with the through holes described in the drum container body;The plastic bottom cover has a surface with a circular projection and an orthogonal projection with a flange, concentric channels, a central recess, indentations, and ribbed grooves arranged throughout the circular projection of the cover. Said cover has a chamfered area on the edge of the surface, embossed grooves, longitudinal reinforcing grooves, and carrying handles that have transverse grooves with a negative inclination on their lower portion, originating from the circular projection to the edge of the flange, coinciding with the through holes described in the body of the drum container, the inner face of the cover.

[0018]

[0014] The drum container shown in the document above has a banding on the upper and lower edges, which allows for drainage points in the body area.
