A concave barrel opening seat positioned at the center of a cover disk at the top of the plastic cover barrel and a barrel opening tube are arranged according to the plastic cover barrel of the present invention, and the diameter of a barrel opening is at least 100mm or over 100mm (the picture 1).

Description

Plastic Drum

The present invention relates to a kind of Plastic Drum, it mainly is columniform bucket wall that this bucket has, at the bottom of the flat dish-shaped bucket and a corresponding bung, a sealable bung can also be arranged, and have one to be used to the hoop that supports and carry, outer barrel wall near the bucket top have a level down with the vertical areal of support of gripper that is used to support claw grasping device inwardly.

Have the plug type bucket of conventional bung only to be suitable for storing and transport liquid, this is owing to bung little (2 inches), so such bucket is unsuitable for viscosity or particle shape article.

Owing to need auxiliary equipment (large-scale lid and clamping ring), so be generally used for storing and transporting viscosity or solid article, as: pitch prill, coating, inspissated juice, the lid type bucket of particle and bulk product etc., expense is relatively more expensive, particularly in some simple application, as: stone transporting English sand mold product, plastic grain [as expanded polystyrene (EPS)], and its dropping characteristic is poorer than leak free plug type bucket.

Task of the present invention just provides a kind of Plastic Drum thickness or the quarz sand series products that is specially adapted to transport.

This task is to produce the bucket of low production cost, and just can carry with common folder bucket instrument.

According to the present invention, the solution of this task is that a bung attaching parts is installed on sunk bung seat, and this attaching parts is coaxial with the bung of general Plastic Drum, and bung bonded assembly diameter is at least 100 millimeters or more.

The bung attaching parts diameter that a kind of preferred designing institute provides is about 150 millimeters.In another special case, the diameter of bung attaching parts is about 225 millimeters.Its advantage is, only the specification of these diameters just can be used on the bucket in various buckets footpath, (as 1201,2201) according to the bucket that reaches L type hoop that a coaxial screw top is arranged of the present invention, its productive costs is lower than standard cap bucket, and the better dropping characteristic than the latter is arranged, and compares with big bung, the helix cover also can be produced (because they only have two kinds of specifications) under low cost, and the cost of an auxiliary clamping ring also can be ignored.Therefore it is feasible providing a kind of bucket of screw top cheaply, this barrel promptly is applicable to the loading of above-mentioned quarz sand series products of mentioning and granular pattern article respectively, can be used for loading inspissated juice in heaps and food or thickness again, compare with the cylinder of lid type, screw top type bucket of the present invention is because its top is useful on the hoop (MauserL one ring) of supporting and transportation, and making it that more advantage be arranged, it can use and carry steel or screw top type bucket is carried and handled to the identical gripping tool of plastic plug type bucket.

In decision design, the blowing of the part of whole staving forms.In fact, bucket is welded by two parts (or three parts), i.e. the column type staving of the top of an independent injection mo(u)lding (＜perhaps be the bottom of mold pressing) and an extrusion forming.

In addition, according to bucket of the present invention, also can equip a kind of annular on the bucket base, firm convex type rolls ring, and it is positioned at the turning point at outer barrel wall and the smooth barrel end.

A key character of the present invention is: no matter have the volume of the bucket of L type hoop how to change (as 601,1201,1501,1601 even 2201), the specification of preferred two kinds of screw tops is unmodifieds.The external diameter of bigger screw top is about 270 millimeters, and the external diameter of more small-sized screw top is about 180 millimeters.

At this, it is in order to have the screw top of inward turning screw thread to match with of the present invention that the bung attaching parts has an outside thread, and 2 inches little bung attaching parts of common plug type bucket always has negative thread, and attached plug screw has a corresponding outside thread.

Stipulated to be screwed to the height of the screw top on the bung attaching parts in order to realize the present invention.The top of screw top is pushed up high or almost concordant with bucket together with bucket or is lower than the bucket top.

Just in case bucket when falling, a spiral that recessed bucket top core barrel stomatodeum is fallen into the position is stamped a best protection like this, and will be never and the ground direct contact.

The present invention is further illustrated and description below in conjunction with drawings and Examples:

Figure 1 shows that lateral plan, the part sectional view of a kind of screw top bucket of the present invention; Figure 2 shows that the bucket top margin cross sectional drawing of king bolt lid; Figure 3 shows that the bucket top margin cross sectional drawing of minor spiral lid; The section that the minor spiral lid is arranged and be used for the additional bung of material in the complete emptying bucket shown in Figure 4

Figure; Figure 5 shows that the top view of a kind of screw top bucket of the present invention; Figure 6 shows that the transparent view of another kind of screw top bucket according to the present invention; Fig. 7 is the cutaway view at bucket shown in Figure 6 top; And Fig. 8 is the top view of another kind of screw top bucket.

In Fig. 1, reference number 10 expression is according to a kind of Plastic Drum of the present invention, and this bucket has 14 and corresponding barrel tops 16 at the bottom of 12, one dish-type buckets of a column type bucket wall.Break over region between outer barrel wall 12 and bucket top 16 has one to be used to the hoop 22 that supports and transport, and this hoop has the vertical areal of support 26 inwardly with of level areal of support 24 down, as commercial barrel of gripper equipment claw, above steel drum is molded.

At the center on bucket top 16, the bung seat 28 that bung attaching parts 30 is arranged, this bung attaching parts rise from the baseplane 40 of bung seat or protrude, and outside thread is arranged above.

The internal diameter of bung connection 30 and the internal diameter of bung 20 (18) are respectively 100 millimeters or bigger at least, and have the screw top 34 (32) of screwing on of corresponding negative thread to realize airtight and the watertight function by one.

The minimum diameter of bung attaching parts must not be lower than 100 millimeters, because bung should pass through even as big as the hand that makes the people at least.If after this bucket had used several times certainly, the bung that this is minimum was very easily to thorough washing bucket inside.

On the contrary, bung can not arrive half of bucket footpath greatly, such work, and the resistance that will lose and drip of the advantage on the cost may reduce.For example, because the strong elastic deformation in top can cause the seepage of screw top.

Figure 2 shows that the top graph of big bung 18, the internal diameter of its bung attaching parts 30 is 225 millimeters.Summit on the bucket top is measured, and the diameter of bung is between 300 millimeters to 400 millimeters, and the best is about 330 millimeters.The baseplane diameter of bung seat is between 250 millimeters to 330 millimeters.The best is about 270 millimeters.The bulge loop that is used to connect Wrench is equipped with on the surface that external diameter is about 270 millimeters bigger screw top 32.

Figure 3 shows that the optimum design that another has less bung 20, the internal diameter of its bung attaching parts 30 is about 150 millimeters.The diameter of measuring the bung seat on the summit at bucket top is between 200 to 300 millimeters, and the best is about 230 millimeters.The diameter of the baseplane of bung seat is between 180 millimeters to 250 millimeters, and the best is about 190 millimeters.External diameter is about 180 millimeters less screw top 34 horizontal surface, and smooth disc-shaped surface and screw top meet at right angle highly being about on 40 millimeters the flange.Go out the flange of some flutings in the mold pressing of the outside of flange, when covering, can increase the grip of hand when screwing on.Flange has a screw thread, and bung attaching parts 30 has an outside thread that adapts with it, with flange at a distance of a bit of distance, be molded with second bulge loop, it is short slightly, also meets at right angle with it.The U type groove that an annular is arranged between interior outward flange.A sealing member is arranged in this groove, be used for the bung attaching parts 30 that faces toward with screw top towards top edge.

In this design, the top that is screwed in the screw top on the bung attaching parts is between the top, top of bucket top and supporting and transportation hoop 22.

In a design of not drawing in detail, the top on bucket top will be higher than the height that is used to the hoop limit face that supports and transport.

When similar bucket stacks, just produce a kind of interior pressure of load-bearing before being sent to supporting and transportation hoop in an advantageous manner stacking load.

Figure 4 shows that cutaway drawing according to another aspect of the present invention, bucket top 16 also has second closed keg mouth 38 except having outside the large diameter screw top mouth (18,20), and it is near edge of lid mouthful, so that be emptied completely the material in the bucket.In the blowing mould process, keeping the bottom (inside) of bung 38 is useful for closed state.Only can drill the side opening of threaded connector when needed, or perforate on the chassis of threaded connector.Bung 38 can be close with a unsuitable commercially available plug screw envelope.Shown in the present, the top on bucket top 16 is lower than the top of supporting and transportation hoop 22 limit faces 36, and screw top 34 a little higher than bucket tops 16.

This design has produced that a central pivot point and one are stacked by bucket of the same type and the annular fulcrum that produces.

Yet, in the design's a remodeling, the limit face 36 of hoop 22, the threaded

cap

32,34 on bucket top 16 and the bung attaching parts 30 also can roughly be installed in sustained height.

Fig. 5 is the top view of bucket shown in Figure 4, additional bung 38 can be set, but always not need, and for example, can be provided with when being used to load particle shape article.

In a kind of further improved design shown in Figure 6, bucket top 16 has a drainage channel 42 radially at least, and it leads to in-to-in bung seat 28 and leads to clamping slot 44, and draw-in groove 44 is positioned at the hoop rear side, towards its outer circumference.

If this type of bucket stores outside, its radially drainage channel 28 accumulate in bung seat 28 with regard to having prevented a large amount of rainwater, use the method, the rainwater that bung seat 28 accumulates just can enter into the draw-in groove 44 of hoop 22 back from groove 42 outflows.At least in a place, best all have drain gutter for several places, and the drain gutter that leads to draw-in groove 44 bottoms passes the face of joint of hoop, and like this, rainwater just can not accumulate in the draw-in groove 44 of itself.

In Fig. 7, another feature of the present invention realizes.To discharge the bung article fully and need state in order to improve 180 ° of bucket upsets, top some inclination slightly of bucket, be the normal position of bucket seen in the figure, while interior the resistates of bucket removing mouth 38 arranged be higher than about 2 millimeters～12 millimeters relative with it, the best is 8 millimeters.

The diff-H of about 8mm also shows in Fig. 4.A segment distance of arrow indication among promptly following barrel top dotted line and the perpendicular figure.When this type of bucket stacks, by screw top 32 central pivot point is arranged, and become the circumference fulcrum by the hoop 22 of end bucket.

In order to realize a barrel top zone line stacking strong point, crown part 46 can be installed in the surface on bucket top, and as shown in Figure 8, the top of crown head parts 46 flushes with supporting hoop 22.In design shown in Figure 8, the crown part 46 of 8 boss types is equally spaced.In fact, crown part can have difformity, for example: and rectangle or square, and can make with bucket while blowing mould, or as the bonding or welding with bucket of independent injection-moulded component.Be easy to have the whole bucket top of hoop, bung attaching parts and crown element, then the bucket overhead welding received staving and get on the molding process manufacturing.

So screw top bucket according to the present invention is specially adapted to granular pattern and liquid article, big bung mixer also easy to use (splash bar).For example: have the product (as zinc oxide coating) that separates tendency to need to mix and make it even before being transported, this bucket also is suitable for repeated use, and is because compare with common plug type bucket, capable of washing clean in its bucket.

In addition, using the thin-walled plastic internal layer as a kind of osed top the bucket of L type ring to be arranged on big mouthful of container first is the problem that do not have.

At last, in order to enlarge the field of application of the screw top bucket that L type ring is arranged, make article that the trend of exhaust be arranged, threaded cap 32 as shown in Figure 8 has a plug screw 50 that sets exhaust gear 48 on it, is to prevent to produce in the bucket overvoltage.

The bucket that screw top and L type hoop arranged according to the present invention naturally also can device has the ring that rolls of circular table.
