Description

The inventive utility model relates to containers for storing and transporting liquid, grease and bulk solids and can be used in food, pharmaceutical, chemical, oil refining and other industries, as well as in agriculture.

For packaging, storage and transportation of various food products, medicines, perfumes and cosmetics, household chemicals, paints and varnishes, industrial oils and lubricants, industrial and household products, as well as dangerous goods, hermetically sealed containers are used. In the production of plastic shipping containers, one of the leading places is the production of cans. Everywhere, transportation containers are subject to certain requirements: safety, inadmissibility of leakage of contents, transportation requirements - impact resistance, withstanding pressure, load, vibration, temperature and humidity differences.

Known canister containing a housing including side walls, a bottom, an upper wall with a handle and a neck located in the central recess, stiffeners, stacking elements on the upper wall and the bottom of the housing, characterized in that the transition from one side surface to another is made at an angle of 90º by smoothly rounding a surface section with a wave contour in cross section with the number of oval, longitudinal along the canister body, protrusions of at least 2, which are stiffness elements of the canister body, p At the same time, the height of the oval protrusions does not extend beyond the dimensions of the canister body in width and thickness, and the side walls of the canister are formed by external rounded surfaces with a radius of curvature significantly exceeding the overall dimensions of the canister, while the stacking elements are made in the form of two symmetrically located rectilinear support-fixing protrusions located on the upper wall of the canister, and opposite the recesses located in the bottom of the canister, repeating the shape of the support-fixing protrusions (RF patent for Utility Model. 114035, IPC B65D 1/00, publ. 03/10/2012).

 The disadvantage of such a canister is, for example, the absence of a recess at the bottom, which facilitates the capture of the canister from below by hand, which can lead to damage to the canister when it falls, which does not preclude the spill of liquid. Another significant drawback is the execution of the side walls of the flat and vertical edges of the canister straight, which can lead (and in practice leads) to a change in its shape (shape transformation) after pouring liquid and stacking during transportation and storage of canisters.

  Also known is a canister containing a body formed by side, upper and bottom walls, with a neck and a handle made in the upper part of the body, characterized in that the neck and handle are located in a recess formed in the middle of the upper wall, the body ribs are provided with profile stiffeners , on the upper and bottom walls of the housing stacking elements are made in the form of support-fixing protrusions and nests, while the bottom wall of the housing has a recess for gripping the canister, a rectangular recess in the middle part with rounded walls and opposing recesses, one of which is made lowering relative to the other and is associated with a recess for gripping the canister (utility model patent 146336, IPC B65D1 / 00, published on 10/10/2014).

  According to the patent, the body has the shape of a parallelepiped, which is a section in the form of a rectangle with rounded corners.

Also, according to the patent, profile stiffeners are made in the form of at least two grooves parallel to each rib of the housing, and the grooves are oval.

Also, according to the patent, the stacking elements are made in the form of vertical truncated cones, pairwise mounted relative to the handle on the upper wall of the housing, and conical recesses opposite to them on the bottom wall, while the latter has two supporting protrusions in the form of vertical truncated cones.

Also, according to the patent, the recess of the upper wall is made along the longitudinal axis of symmetry of the canister, gradually expanding towards the neck and passing into the seat under it.

Also, according to the patent, the recess for capturing the canister is made in the form of half an ellipsoid formed by different radii.

Also, according to the patent, on the outer surface of the neck a resistant thread is made with a profile of an unequal trapezoid and an angle between the sides of 45 °.

Also, according to the patent, a ring gear with a protrusion and tooth pitch equal to 30 ° is located at the base of the neck.

Also, according to the patent, the handle is made in the form of a hollow rectangle with rounded ribs, while one end of the handle is paired with the upper wall and is parallel to the excess of its plane, and the other is bent at an obtuse angle to the latter, and forms an acute angle with the base of the recess.

Also, according to the patent, the canister is made of low pressure polyethylene by extrusion blow molding.

The disadvantages of this canister is the design and arrangement of the stacking elements, in which even a slight deformation of the upper or lower bottom significantly interferes with the docking of the elements. In this case, the docking of the elements should be carried out carefully, which is difficult to do when manually installing the canisters in the stack. Practice has shown that the shape of the parallelepiped at the base of the canister provokes deformations in the region of the upper and lower quarters of the ribs, with an increase in internal pressure and simultaneously load from above. The shape of the canister in this case tends in the middle to the ball, and the upper and lower bottom hold the parallelepiped shape, creating creases on the ribs inward. Another disadvantage is the low stability of the rounded shape of the ribs against squeezing of canister groups from stretch-film winding, which favors deformations with a characteristic crease of the ribs inward. In addition, all the side walls of the canister in the middle part are made flat, and the ribs of the body with profile stiffeners are also straight in the middle part, which means that the side walls and vertical ribs can transform (they tend to transform), changing the shape of the canister after filling liquids and stacking during transportation and storage of cans.

Also known is a canister containing a housing formed by the front, rear, side, upper, and bottom walls, with a recess in the middle part made in the upper wall, in which the neck and handle are arranged, vertical ribs are made with profile stiffeners, in the upper and bottom walls the hulls are made with stacking elements, the front and rear walls are made without flat sections and in the longitudinal section are barrel-shaped-arched, and:

 Stacking elements are made on the upper and bottom walls of the body:

on the upper wall - in the form of a U-shaped protruding rim with rounded

corners, forming a recess for the handle, and two protrusions on the long sides of the rim, facing outward and connected together with a U-shaped protruding rim, and in the bottom wall there is a recess of rectangular shape with rounded corners corresponding to the protruding rim in the upper wall for stacking the canister, in the front and rear parts of this recess there are continuing recesses in the form of strips with slightly rounded corners, and in the middle of the recess perpendicular to the longitudinal axis, recesses extending from the recess are made, with tvetstvuyuschie protrusions in the central part of the top wall,

- in the bottom recess are made perpendicular to the longitudinal axis of three rectangular recesses on each side, increasing the rigidity of the bottom wall,

- in the bottom recess from the side opposite the neck, inside it and adjacent to its rear border, a recess is made to capture the canister by hand,

- the left and right side walls in the middle part have flat slightly recessed surfaces, and in the lower part there are vertical and semicircular recesses in the cross section, forming stiffeners (http://www.zti.ru/category/kanistry-21-5-litr/ to-21-5-l-ks /).

As already noted, in practice, the shape of the parallelepiped at the base of the canister provokes deformations in the region of the upper and lower quarters of the ribs, with an increase in internal pressure and simultaneously load from above. The shape of the canister in this case tends in the middle to the ball, and the upper and lower bottom hold the parallelepiped shape, creating creases on the ribs inward. Therefore, a canister can be considered approaching the ideal shape, in which, initially, when designing, a certain spherical or barrel-like shape in the middle of the canister is combined with a reinforced configuration of the zones of the upper and lower parts of the ribs. Therefore, a certain disadvantage of the above analogue can be considered insufficient implementation of the above concept of the shape of the canister, due to the small curvature of the vertical ribs. In terms of stacking, the disadvantage of an analogue is the implementation of a U-shaped protrusion in the form of a continuous long line with roundings, which provoked a possible difficulty in stacking cans in the rounding zone.

Those. the analog is a prototype of the more advanced design of the canister described in this application. Structural and technological changes in the claimed utility model concerned the configuration of vertical ribs in terms of increasing curvature (increasing barrel shape) and reinforcing the upper and lower parts to increase their stiffness and preventing creases in the corners of the canister, increasing the curvature of the front and rear walls (increasing barrel shape), a significant change in elements stacking on the principle of creating these elements on the upper wall is not in the form of a single solid element, which is subjected to greater deformation in the process e operation of the analogue, and in the form of intermittent stacking elements (claimed utility model), as well as significant processing of the upper and lower walls of the canister, as described below. The inventive utility model is a significant development of the prototype and the new concept of the canister. The author and applicant of the utility model is directly related to the development of an analogue.

Known canister containing a housing formed by the front, rear, side, upper and bottom walls, a recess is made in the middle wall in the middle part, in which the neck and handle are arranged, the housing contains vertical ribs, stacking elements are made in the upper and bottom walls of the housing, the front and the rear walls are made without flat sections and in longitudinal section - barrel-shaped arcuate (US 7059486 B2, 06/13/2006, Fig. 1, 2 [0025] - [0039]).

  A subject of the invention according to the US patent is the creation of vertical ribs expanding in the upper and lower parts of the canister and with smooth curvature in the upper and lower parts of the ribs when moving from the rib to the upper or lower wall, when viewed in vertical sections. This is done to reduce the collapse of the corners of the ribs. The essence of the technique for rounding the corners of ribs in plastic cans has long been known. In this case, the vertical ribs in the middle part are made almost straight, especially in versions using a removable plug-in middle part of the mold to change the volume of the product during blow molding, as described in the patent. This design of the ribs is a definite disadvantage of this analogue.

In addition, the canister of the patent is characterized in that in the recess of the upper wall there are protrusions or concavities of an oval shape in the direction perpendicular to the handle.

The author and patent owner of the patent of the Russian Federation 188035 is the author and applicant of this utility model.

The decision on the patent of the Russian Federation 188035 is taken as a prototype.

The problem is that the patented ratios for the parameters of the side barrel-shaped ribs, as well as the structural stacking elements and the profiles of the upper wall and the bottom, are typical for certain standard sizes of cans. Calculations and experimental verification show that for other sizes of cans, for example, with a small volume of about 5 liters, structural changes are necessary.

The technical result of the claimed utility model is to improve the strength characteristics of the canister of relatively small volumes (about 5 liters) due to the rigidity of the body and ribs with increasing the resistance of the canister to deformation under pressure from above.

The above generalizing technical result, in particular, is to increase the rigidity of the side barrel-shaped ribs by changing the parameters of the longitudinal and transverse dimensions of the ribs, tied respectively to the longitudinal length of the canister and its width. Such ratios of the longitudinal and transverse dimensions of the ribs in the projection are preferable for canisters with a volume of about 5 liters.

In addition, the above generalizing technical result, in particular, is to optimize the stacking elements by changing their design, providing them with additional reinforcement.

In addition, the above generalizing technical result, in particular, consists in additional special profiling of the bottom surface, thereby excluding the possibility of deformation of the bottom of the refilled canister, including during loading and unloading and during storage.

An additional technical result of the canister is to ensure simplicity and possible freedom (with a 180 degree turn) of stacking the canister during operation.

The technical result is achieved by solving the technical problem of creating

a canister containing a body formed by the front, rear, side, top and bottom walls, a recess is made in the upper wall in the middle part, in which the neck and handle are arranged, the body contains vertical ribs, stacking elements are made in the upper and bottom walls of the body, the front and the rear walls are made without flat sections and in the longitudinal section are barrel-shaped arcuate, the vertical edges of the body have a convex barrel-shaped arcuate profile in the longitudinal section from above and below, including the profile element stiffness, while the optimal convexity (K) of the rib is from 0.005 to 0.02 of the height of the canister (N) and is measured in the projection of the rib on the plane as the distance between the points at the levels of 0.06 N and N / 3 in the lower part of the canister and between the points at the levels of 0.08N and H / 3 in the upper part of the canister, the vertical ribs in the middle part being made straight and the dimensions of the canister ribs in cross section are calculated as follows:

1) the longitudinal size of the ribs in the projection (L Ave.) = L / 5 ± L / 8,

2) the transverse size of the ribs in the projection (L cross.) = B / 4 ± B / 6,

where L is the length of the canister in the longitudinal direction in a plan view;

B is the width of the canister in the longitudinal direction in a plan view.

As already described in the prototype, the barrel-shaped shape of the ribs and walls is the main feature of the claimed utility model. The product loses in volume, but acquires the greatest strength under the action of pressure from the inside and from the top. In contrast to the previously developed and manufactured canisters having a parallelepiped shape, the inventive canister has a shape based on it that approximates the shape of a flattened barrel.

Those. the shape of the ribs ideally and the canisters in the longitudinal section are barrel-shaped, without flat sections. Due to the barrel-shaped ribs and the roundness of the upper and lower bottoms in cross section, the shape of the canister is close to the ball, which makes it less likely to deform at the corner / body transitions under pressure from the inside and under load from above

Thus, the concept of the canister developed by the applicant, according to the claimed utility model, is based on the desire of the canister, under internal and external influence, to acquire a shape approaching in the middle to the shape of a ball (theoretically) or a barrel, i.e. to barrel-shaped form. Therefore, used in relation to the claimed utility model, the term "barrel-arcuate" in relation to the front and rear walls and vertical edges of the canister is justified, as it most fully reflects the essence and feature of the claimed design of the canister.

      The execution of the ribs in the middle part is straight due to the small size of the canister, although they can be made with a slight curvature, which does not change the essence of the claimed utility model.

In addition, the canister is characterized in that the vertical ribs of the body have three protrusions extending from both sides to the base surface of the ribs, while the middle protrusion is made larger than the others. As a rule, the protrusions have small radii of curvature.

Those. the shape of the ribs in cross section has three distinct protrusions, playing perhaps the main role in increasing the rigidity of the ribs as a whole. The increased width of the ribs and the small radii of the side / rib transition increase the rigidity of the canister and the resistance of the ribs to compression from stretching with a stretch film of a group of canisters, before sending them to consumers, as well as during operation of filled canisters.

The main thing is that the vertical ribs of the body have a convex barrel-shaped arched profile in a longitudinal section, ideally along the entire length, while the number of protrusions is not critical.

 In addition, the canister is characterized in that the base surface of the rib is calculated in horizontal section in accordance with the longitudinal and transverse dimensions of the rib in the projection and is in this section a convex or straight line connecting the edges of the side walls with the edges of the front or rear walls of the canister, This protrusion along the ribs go to the radii of the transitions of the rib-bottom, reaching the bottom of the canister. This ensures maximum rigidity of the canister in these places.

In this case, the baseline can be visible or virtual, but it is used in the construction of the edges. According to experts, it is the combination of the base surface and the shape of the protrusions that plays an important role for stiffness.

In addition, the canister is characterized in that the stacking elements on the upper wall of the canister are made in the form of three support-fixing protrusions.

In addition, the canister is characterized in that three supporting-fixing protrusions on the upper wall are made along the boundaries of the recess:

- rear protrusion - in the form of an arched protrusion, repeating inside the notch border, having approximately the same width, adjacent to the handle and having fillets with radii of at least half the width of the protrusion from the sides in the adjoining zones, the upper parts of the handle and the rear protrusion being on the same surface protrude above the upper wall of the canister;

- two oblong protrusions on both sides of the handle, and the protrusions are located at the same distance from the longitudinal axis of the canister and in the middle of the length of the canister.

From the point of view of the utility model, this means that the three support-fixing protrusions on the upper wall protrude above its surface and are made mainly outside the recess, since part of the handle for gripping it with your hand can be either protruding and flush with the rear protrusion, or slightly submerged. This is due to the essence of the utility model: the main support-fixing protrusion in the link “handle - rear protrusion” is the rear protrusion.

For a possible variant of the canister with free stacking, side protrusions can be made in the middle of the canister.

So the implementation of the rear protruding side, which is a continuation of the handle and the handle itself, protruding above the horizontal surface of the upper wall serves to securely lock the canister when stacking, including when choosing the option with free installation of it with a possible turn of 180 degrees.

 The fixing protrusions on the upper wall and the recesses on the bottom wall of the canister are located in the zone of best control from the standpoint of blowing technology. The wall thickness on two lateral protrusions (stops) can be controlled by the PWDS system (dynamic adjustment of the workpiece thickness in cross section), and the rear protrusion (emphasis) is located in the area of the closing line, where the thickness is always guaranteed.

In addition, the canister is characterized in that the bottom wall has a profile and recesses, including, for the appropriate placement in them of the support-fixing protrusions of the upper wall of the canister, namely:

- front recess located under the neck,

- a rear recess made in the rear of the bottom wall,

- a recess made along the longitudinal axis of the bottom wall of the canister and connecting the front and rear recesses,

- two oblong recesses made on both sides of the longitudinal axis of the bottom wall of the canister and located opposite to the corresponding elongated protrusions on the upper wall of the canister,

- the middle part of the bottom recess of an approximately flat surface, passing along the perimeter of the recess to the rising part of its surface to the border of the bottom recess with the supporting surface of the bottom, while the middle part of the bottom recess has transverse elongated corrugations, and their length can be constant for medium corrugations and increased for the corrugations located next to the front and rear recesses in the bottom, and mainly, the corrugations are concave inward,

- the raised part of the bottom in the middle part in a front view in the area of the holes for the rear protrusion and neck.

In addition, the canister is characterized in that the side walls have upper and lower protruding parts and a middle recessed part, while the lower part has vertical elongated lengths and semicircular recesses in the cross section, increasing its rigidity.

In addition, the canister is characterized in that the recess of the upper wall is made along the longitudinal axis of symmetry of the canister, gradually tapering towards the neck, covering its seat and ending on the front wall of the canister body.

In addition, the canister is characterized by the fact that a handle in the form of a hollow rectangle with rounded ribs is made in the recess of the upper wall, while one end of the handle (rear) is flush with an arched protruding side, parallel to the upper wall and its plane is exceeded, and the other is bent under obtuse angle to the latter and forms an acute angle with the base of the recess,

In addition, the canister is characterized in that the front and rear recesses in the bottom wall of the canister are made in a shape close to the shape of a trapezoid with a rounded long side.

In addition, the canister is characterized in that the stacking elements are made as follows:

- lateral protrusions on the upper wall of the canister are located at the same distance from the longitudinal axis of the canister, in addition, they are located in the direction along the longitudinal axis and are located in the middle of the bottom wall of the canister, on the transverse axis of the canister;

- front and rear recesses in the bottom part at any of the canister positions: both the “cork above the cork” and with a 180-degree turn are in opposition with the neck and rear protrusion on the upper wall of the canister body.

    Of course, the configuration and dimensions of the support-fixing protrusions in the upper wall and the corresponding configuration and dimensions of the recesses in the bottom wall are made with gaps that provide reliable stacking of the canister as a “cork over the cork”, and subject to the above conditions, with its 180 ° turn as well as a comfortable and free grip with her hand.

The canister can be made both for free stacking and in a fixed version, with one or two recesses, as well as in the case when a recess is made in the bottom wall only in the back.

The preferred embodiment is the execution of the canister for free stacking, i.e. with two recesses in the bottom wall. The advantage of this option also lies in the fact that the implementation of the "optional" recesses in the bottom wall, for example, under the neck, leads to an increase in the rigidity of the bottom wall of the canister, because the presence of two recesses at the bottom reduces the area of a flat section at the bottom and prevents deformation of the bottom under load.

In addition, the canister is characterized by the fact that on the outer surface of the neck a resistant thread is made with a profile of an unequal trapezoid and an angle between the sides of 45 °.

In addition, the canister is characterized in that the canister is made of low pressure polyethylene by extrusion blow molding.

Figure 1 presents the canister with a neck, without a lid. The canister contains a housing 1, consisting of a front 2, a back 3, side 4 and 5, an upper 6 and a bottom 7 walls, a carry handle 8 made in the upper wall 6 and passing through the longitudinal axis of the canister, a neck 9. The body has a horizontal section an approximate shape of a rectangle with cropped corners on which vertical ribs are made. The body of the canister is made of low pressure polyethylene. The vertical ribs 10 of the body have a generally convex barrel-shaped arcuate profile in longitudinal section along the entire length and are equipped with profile stiffeners made in the horizontal section B-B (Figs. 7 and 8) in the form of three protrusions - teeth 11 that extend outside in a line 12 (Fig. 8), which are part of the cross section of the base surface of the ribs, with the middle protrusion-tooth made the largest, and the edges of the protrusions-teeth made rounded small radii. The middle protrusion-tooth is made in a vertical section of a pronounced barrel-shaped arched shape (Fig.7). Other profile elements are also made barrel-shaped-arc-shaped, but may have a slightly different curvature from the middle protrusion-tooth.

The middle parts of the side walls 4 and 5 are made almost straight or may have slight curvature in the vertical section and with a large radius of curvature in the horizontal section, and are recessed into the body, i.e. sidewalls have protruding upper and lower parts. This was done specifically for the convenience of sticking labels and tags with information about the contents of this canister and for the greatest safety of these labels and tags during transportation, as damage due to friction is reduced (the contact area is reduced due to the diminution of this area). The front 2 and rear 3 walls are made of convex barrel-shaped with radii in the longitudinal and transverse sections, and in the cross section is the radius of large curvature.

The upper wall 6 has a recess 13 formed in the center along the longitudinal axis of symmetry of the canister and having straight sides on the top view, an arched shape at the back with relatively large radii of curvature and a front part covering the seat of the neck 9 and facing the front wall of the canister body. Thus, the upper part of the handle 8, in the presented embodiment, is made protruding above the plane of the upper wall 6 (Figure 5). Stacking elements are made on the upper wall 6 of the housing 1 - support-fixing protrusions 14 in the form of a T-shape, as well as a rear protrusion (side) 15 of an arcuate shape, which is a continuation of the rear of the handle 8. In the main version, all three protrusions are made along the border of the recess thirteen.

On the bottom wall are made, respectively, protrusions on the upper wall, sockets 16 (Figure 2), as well as the front 17 and rear 18 recesses. These recesses can be made slightly different or the same depending on the task. Under certain conditions, in the embodiment for free stacking, the recesses can be made of the same shape, which allows stacking to be placed in any of them - both the neck 9 with a stopper (not shown) and the rear protrusion (side) 15. Front 17 and rear 18 recesses connected by a longitudinal groove 19 (Figure 2, Figure 4) to accommodate the protruding part of the handle 8 when stacking.

In a longitudinal section, the handle 8 of the canister has a different profile and the middle and rear parts are raised relative to the horizontal surface 6, and the back part goes into the rear protrusion (side) 15. Thus, the handle and side 15 play the role of the back support-fixing protrusion, and the corresponding opposed the recesses 17 or 18 in the bottom wall 7 of the canister for the rear protrusion and the groove 19 connecting the recesses 17 and 18 for the handle 8, further contribute to the improvement of the stacking of the canister.

The described stacking elements prevent distortions and are designed to ensure that when stacking the canister is more stable in a horizontal position and is evenly stacked on top of one another for more even load distribution. The support-fixing protrusions 14 of the upper wall 6 of the body when stacking cans enter into sockets 16 on the bottom wall 7 of the canister, and the side 15 enters the back (in variants - any) of the recesses 17 or 18 with a minimum gap, which together prevent the canisters from slipping off relative to each other during storage and transportation. When stacking canisters, recesses 17 or 18, in which the horseshoe-shaped rim 15 does not fit, are used to grip the canister by hand. This is a useful constructive advantage of the canister. A variant of a canister with one lower recess is also allowed, although with this design the rigidity of the bottom wall decreases and the variability during stacking decreases.

The handle 8 is made in the form of a hollow rectangle with rounded ribs and is formed in the center of the upper wall of the canister, while one end of the handle is connected to the upper wall 6 and is located in excess of its plane, and the other is bent at an obtuse angle to the latter, and forms an acute angle with the base notches 13.

The lateral walls 4 and 5 of the canister have in the middle part flat or slightly arched recessed surfaces, and in the lower protruding part there are vertical oblong and semicircular recesses 20 in section, forming stiffeners.

Figures 9-19 show views of a canister depicting a portion of significant zones, as well as places of significant sections and corresponding sections.

Significant areas are indicated by a square hatch or a dashed line. When designating zones, the letter “a” is added to the number of the corresponding position (Fig. 1-8). Sections are indicated by capital letters of the Russian alphabet. Sections disclose in detail technical solutions that generally allow to obtain the necessary technical result.

In FIG. 12 shows the zones of the recesses 17a and 18a in the bottom wall of the body, affecting the increase in rigidity of the bottom wall 7, as well as the zones of the lateral vertical recesses 20a, affecting the increase of rigidity of the lower parts of the side walls 4 and 5 of the canister body.

On Fig shows the area 10A of the vertical ribs, significantly affecting the stiffness of the housing as a whole. The dimensions of the ribs calculated for this utility model provide their optimal design and the design of the canister as a whole. An important element is the execution of the ribs in the upper and lower parts, where in combination with the protruding upper and lower parts of the side walls, these parts of the ribs form a reliable execution of the corners of the canister from jamming them during operation.

In FIG. 14 presents the parameters for calculating the edges according to the utility model, taking into account the length (L) and width (B).

In FIG. 15, the place of the vertical section C along the middle (central) protrusion of the rib is indicated, and in FIG. Figure 16 shows the corresponding CC section with parameters for determining the curvature of the rib depending on the height of the canister body (H). In FIG. 15 also shows the location of the vertical section T along the front wall 2 of the canister body, and in FIG. 16 shows the corresponding TT section.

In FIG. 17 shows a zone 14a with a lateral support-fixing protrusion 14 on the upper wall, FIG. 18 shows the cross-sectional point FF along this protrusion, taking into account stacking on a canister on top of another similar canister, and FIG. 19 shows the cross section FF itself.

In FIG. 17 also shows the area 15a of the rear protrusion 15 on the upper wall.

In FIG. 18 is a cross-sectional location XX, and FIG. 19 shows section XX itself, along with a section above the canister to be installed.

In FIG. 17 also shows the location of section P, and its section PP is shown in FIG. 10.

The canister is made by extrusion blow molding.

The material melted and homogenized in the extruder (low-pressure polyethylene) is squeezed out in the form of a tubular billet, which falls into the mold that is open by this moment. After the length of the workpiece reaches the required value, the half-molds are closed, clamping the lower and upper edges of the workpiece with their sides. When this occurs, the welding of the upper end of the workpiece and the design of the hole for the neck. After the mold closes, compressed air is supplied into this hole through the blow-out pin, under the influence of which the softened material of the sleeve is stretched in all directions and takes the configuration of the internal cavity of the form. As a result of contact with the cold walls of the mold, the polymer solidifies, then the mold opens, the finished product is removed and sent for final processing - additional cooling, removal of burr, checking for leaks and mass. All stages of production are fully automated. If the leak test results are unsatisfactory or when weighing, the cans are rejected automatically. The volume of manufactured cans can be from 3 to 60 liters.

Due to its high strength, both liquid (including high-density) and solid substances can be transported in canisters. This utility model, having high strength, is less prone to deformation during storage and transportation, respectively, there are no leaks and loss of content. This allows you to achieve comparable strength with less polymer consumption. Thanks to this, the maximum economic effect is achieved.

Technical advantages are the creation of a canister that provides maximum body rigidity, increased strength characteristics, reliability and durability, as well as ease of manufacture and operation, simplicity and freedom of stacking.
