Description

The field of technology to which the utility model belongs A plastic barrel with a lid relates to containers for packing, storing and transporting liquid, pasty, bulk substances.

State of the art.

Known plastic barrel (RF patent No. 2268210, class IPC B65D 21/02, published date 10.06.2005), for storage and transportation of liquid, granular and powdery aggregates, containing a conical, stackable body, which is divided into ring segments, the diameter of which increases in steps from the bottom of the barrel to the upper filling opening, and a locking lid for the upper filling opening. In the area of the bottom, inwardly directed stacking stops are embedded in the wall of the blown barrel body, which are in the form of a prism with a triangular support surface to support the barrel bottom of the stackable barrel body. The disadvantage of this design is the complexity of manufacture and the absence of stiffeners.

The closest in design and practical purpose is the "Square can" (produced by the "Samara Plant of Packaging Products" https://www.zti.ru/category/bidony/), including a body, bottom, neck, two symmetrically located handles, a lid ... The body is made symmetrical about the central vertical axis, tapering at the top and turning into a cylindrical neck. On the outer surface of the neck there is a single-start stop thread, by means of which the neck is sealed with a threaded cap through an elastic gasket. The cross-section of the can is made close to square, the profiles of the sides are made arcuate, passing into each other through the lateral vertical oriented projections located along the entire height of the canister, until the lateral sides pass into the base of the neck. In the bottom of the can there is a small round recess with parallel linear projections in the central part. The disadvantage of this design of the barrel is that due to the uneven shrinkage of the plastic during its formation, the upper end of the neck is not flat, and the threads are not located on the helical spiral. This greatly complicates screwing the lid without distorting it at large angles of rotation, requires great effort and the need to deform the lid to fit the shape of the neck for hermetic sealing of the can. Due to the large rotation angles of the lid, there is a high probability of scuffing the elastic gasket mounted in it during its prolonged sliding along the end of the neck, which worsens the tightness of the can closure.

Disclosure of the essence of the utility model.

The technical result of the proposed utility model is to increase the degree of tightness of a closed plastic barrel.

The specified technical result is achieved due to the fact that the barrel includes a body consisting of walls, a neck and a bottom, a lid, two handles, while the neck is made in the form of a hollow cylinder, on the outer surface of which and the inner surface of the barrel lid, along a helical spiral, is made with with the same pitch a four-start trapezoidal persistent thread, interrupted by diametrically located small smooth areas on the neck surface, while the approach from both sections of each of the four threads is unevenly offset by an angle of 10 to 80 degrees.

The technical result is also achieved by the fact that on the inner surface of the lid with a four-way stop trapezoidal thread, in the U-shaped annular recess of the inner surface of the lid, an elastic seal is installed, which provides additional tightness of the closed container.

Implementation of the utility model.

A plastic barrel with a lid includes a body 1, a lid 2, two handles 3 (Fig. 1). The body 1 (Fig. 2) consists of four walls 4, the neck 5, the bottom 6. The walls 4 (Fig. 2, 3) of the body 1 are made identical, including the upper part 7 connecting the base of the neck 5 with the middle part 8 of the wall 4, and the lower part 9 of the wall 4, connecting the middle part 8 of the wall 4 with the bottom 6. The upper part 7 of the housing 1, passing into the neck 2, has diametrically located recesses 10 with the handles placed in them 3. The transition of the upper part 7 into the neck 5 along the rest of the perimeter is made rounded at an angle slightly exceeding 90 ° (Fig. 2).

The cross-section of the body 1 of the plastic barrel is made close to square, the profiles of the sides 4 are made slightly arcuate, passing into each other through the lateral vertical oriented projections 11 located along the entire height of the canister, until the upper part 7 passes into the base of the neck 5 (Fig. 4).

The lower part 9 of the walls 4 with the ratio of the overall height to the middle part 8 of the wall 4 is of the order of 1: 3, with a slight narrowing it smoothly passes into the bottom 6.

The side walls 4 are interconnected by a section in the form of protrusions 11 vertically oriented along the entire height of the body 1, which are also stiffening elements of the barrel body 1.

The neck 5 (Fig. 2, 3) is made in the form of a hollow cylinder. On the outer surface of the barrel neck 5, a four-start trapezoidal thread 12 is made along a helical spiral. The threads 12 on the neck 5 in the area of the handles are interrupted by two small smooth sections 13 located diametrically to each other. The start of each of the four, different in length, threads 12 is unevenly displaced from the generatrix of the neck 5 at an angle of 10 to 80 degrees.

On the inner surface of the cover 2, there is also a four-start trapezoidal thrust thread 14. The threads of the cover 2 are located at 90 degrees. An elastic seal 16 is mounted in the U-shaped annular recess 15, which provides additional tightness of the closed container (Fig. 5).

The threads made in the body 1 of the plastic barrel made in this way greatly facilitate the entry of the threaded surfaces of the cover 2 at the initial moment and prevents the cover 2 from skewing when screwing it in. The multi-start thread ensures the sealing of the closure at small angles of rotation of the lid, which facilitates the process of sealing the barrel and reduces the likelihood of scuffing the elastic seal of the lid with its short sliding path along the end of the neck. This ensures reliable sealing of the barrel closure.

The bottom 6 of a plastic barrel (Fig. 6, 7) is made with a central circular recess and a conical profile of a circular transition from the bottom 10 of the side sides 4 to the bottom 6 of the barrel body 1. Several parallel rectilinear protrusions 17 are made in the central recess of the bottom 6, which are elements for stacking the barrel.

The plastic barrel is made by extrusion blow molding. The cover is made of plastic by injection molding. The capacity of bulk products or liquids for this type of barrels is up to 60 liters. The proposed utility model provides reliable tightness of the closure with less labor costs, which, together with the increased strength and rigidity of the structural elements of the barrel, enables long-term safe storage and transportation of various products in it.
