BACKGROI~ND OF T~l~ INVENTIOI~
This invention relates to a plastic protective ~ carrier or a breakable or otherwise fragile container, r particularly a glass container used to store labGratory ; solvents, acids, or other fluids.
Containers used in the sale and storage of laboratory solvents are often made of glass for a variety of reasons.
Glass pGssesses an inherent lack of chemical reactivity with mGst solvents, glass can be made transparent or relatively opaque depending upon the application, and glass is inexpensive to manufacture. ~lowever, glass containers are also easily broken bv physical shGck, anc means must usually be provided to ensure that the glass container will be protected from bumps, falls, and other physical jostling, both during shipmen-t and in the course of use in the laboratory. This is particularly important where the glass container is carrying a solvent ~hich is corrosive, to~ic, or is one which must be maintained at a pr2cisely defined level of purity or chemical concentration, for in those cases any accidental spillage or unintended b~^eak in container inteqrity could have serious consequences in terms of safety, i~roperty damage, or e.~perimental accuracy.
Protective carriers made of a semi-rigid plastic such as polyethylene have been used for this purpose, these carriers consisting essentially of a large bucket-like container, with a lid and a handle, into which tne glass container may be placed. The polyethylene carrier is made to accommodate standard sized glass solvent containers with only a slight clearance, so that the glass container is held in a relatively stationary position within the container, and is protected from 11;Z2909 ,.
exterllal shock by the walls of the carrier. In !~ractice, inwardly-di~-ected ribs are sometimes used in the walls and the bot~om to position the container within the carrier, thereby allowing for a cushioning airspace hetween most of the inner wall of the carrier and the container.
Protective carriers of existing desiyn, however, have not been totally satisfactory because of one or more shor~comings which relate either to their relative safety or ease of use.
S~ RY OF T~IE INVENTIOi`~
..
The present invention provides an improved protective carrier in the form of a generally cylindrical body for housing a fragile container. The bottom of the carrier is integrally formed on one end of the body. The carrier is provided with a cover which includes a circumrerential lip for engaging a cooperating circumferential flange on the top of the carrier body with a snap fit to hold the lid tightly on-to the body. A handle with an interlockirlg feature is provided for the carrier.
The lid normally inclucles a c3enerally truncated cone-shaped celltral portion. The inside surface of this central portion is dimensioned so as to accomodate a portion of the bottle neck which projects into this central porticn.
A keyway extends generally laterally from this central portion ,or housing the jug-type handle that is often included on the kind of containers that this carrier is intended to house. This keyway serves to protect the handle, and restrict rotational movement of the containers.
The body of the carrier has inwardly projecting ribs whicn extend generally in an axial direction for enga{3ing the side of the container whicn is intencled to be housed by the carrier. The inside diari~eter of the carrier is a predetermined amount grea-ter than the outside diar,~eter of the container intended to be housed so that an air space is provided between the container and the wall of the carrier. The ribs project inwardly a sufficient dis-tance to restrict movement of the con-tainer so as to hold it in a relatively fixed position within the carrier.
The bo-ttom of the carrier also has ribs which are aligned with the ribs on the body of the carrier for supporting the container above the bottom of the carrier.
Although the ribs on the side of the body and the ribs on the bottom are usually aligned with one another to form a generally continuous indentation, it is possible that the bottom ribs could be angularly offset from the side ribs.
The side ribs have a generally U-shaped construction to provide a ~reater contact surface between the rib and the container. The bottom ribs have a generally rounded V-shaped cross section to provide yreater strength for supporting the weight of the container.
The handle for the carrier projects throuyh holes provided on yenerally opposing sides of the upper portion of the carrier. Each end of the handle has a serpentine configuration including a generally inwardly projecting, radially extendiny portion and a portion wnich extends generally tanyentially to the circumferential direction.
The tangentially extending portion of one side of the handle points in the opposite direction from that of the other end of the handle so as to minimize the possibility of the handle twisting loose from the carrier during use.
ll~Z909 The upper surface of the truncated cone-shaped central portion of the carrier lid includes an access hole th~ough which a siphon may be introduced. The carrier of the present invention therefore provides a shock-protection to the container not only during shipment but also while it is being used in the laboratory. The entire container is completely encased within the carrier so that even if laboratory tools are dropped in the vicinity of the container, no part of the container is exposed to possible breakage. The lid can be removed, the container may be opened and a siphon inserted. The lid may then be replaced onto the carrier and the siphon fed through the access hole in the lid.
The method of making the container of the present invention includes a blow-molding process by which the container is made in one piece. The lid is then separated from the carrier and trimmed so that the cooperating portions of the lid and body may conveniently enga~e one another to form a tight lid for the carrier.
The design herein disclosed is believed to be superior in several major respects to those presently available. These design advantages, to be discussed below, can be more easily appreciated by referring to the accompanying drawings.

DESCRIDTION OF T~IE PREFERRED EMBODI.r~ENT
Referring -to the Figures wherein like numerals are employed for like components in the several views, Figure 1 shows the projective carrier with its lid in piace.
The carrier body 10 and lid 30 are made from a low density polyethylene, and are of a thickness sufficient to give a hiyh degree of structural rigidity. Carrier body 10 is generally bucket-shaped, with a series of spaced, linear ribs 12 and 13 molded into the sides and bottom of the carrier body. These in~ardly-directed ribs reinforce the structural rigidity of the carrier body, and, in addition, act as contact surfaces between the carrier body and the glass container being carried, and thereby serve to isolate the glass container within the carrier body from one another. In situations in which the glass container would be subjected to crushing-type forces, these ribs, of generally U-shaped cross section, would act as stiffening agents around the peripllery of the carrier and tend to resist carrier body wall deformation. Under situations in which the glass container would be vulnerable to impact-type forces, includiny those generated by dropping, the ribs maintain a protective air space around most of the glass container and allow the local deformation of the carrier body to absorb energy from the impact with minim.-ll ~amage to the glass container within.
As can be seen from Figure 3, the shape of the side ribs 12 is somewhat different from the shape of the ribs 13 found on the bottom of the carrier body. This was _~;_ ll;~Z909 found advan-tageous in view of the probable weignt distribution withill the c~arrier. In an upright position, the entire weigllt of the glass container will rest on the bottom ribs. By sharpening the apex of the rib on the outside bottom of the carrier body, the corresponding inner rib surface, upon blow-molding, approaches a semicir~ular or V-shaped cross section, which would maximize rib strength with respect to forces directed to the bottom of the carrier body.
Again referring to Figure 3, the bottom of the container body 14 has been designed to maximize container stability when the container is in an upright position.
This has been accomplished in two ways. First, the bottom has been designed to present a relatively flat surface, substantially free of bumps or other surface projections such as rnold marks, identification numbers, etc. In addition, the bottom design calls for a ~elatively small radius of curvature where bottom and side wall meet, as at 15.
This will allow for more contact and support around the outer edges of the bottom, and will greatly increase the carrier's resistance to tipping.
Referring now to Figure 2, handle 20 is made of a single piece of heavy gage metal rod having opposite ends 23 and 24. The rod should be of sufficient strength to resist permanent deformation under maximum forseeable loads--a mild steel rod of approximately 3~16 inch has been found staisfactory. A plastic covering on the handle is suggested to reduce slippage and ofrer some cushioning for the hand.
1~L2Z909 The handle 20 i5 prebent and attached to the carrier body 10 through a pair of opposing holes 21 and 22 in the body 10. Each end of handle 20 is prebent in two places, with a small portion of the handle projecting approximately perpendicular through the carrier wall, and the end-most segment of each said projecting portion being bent so that each end segment of the handle ultimately lies along the inside surface of the carrier. It should be noted that the opposite ends of the handle 20, noted as 23 and 24 in Figure

DESCRIDTION OF T~IE PREFERRED EMBODI.r~ENT
Referring -to the Figures wherein like numerals are employed for like components in the several views, Figure 1 shows the projective carrier with its lid in piace.
The carrier body 10 and lid 30 are made from a low density polyethylene, and are of a thickness sufficient to give a hiyh degree of structural rigidity. Carrier body 10 is generally bucket-shaped, with a series of spaced, linear ribs 12 and 13 molded into the sides and bottom of the carrier body. These in~ardly-directed ribs reinforce the structural rigidity of the carrier body, and, in addition, act as contact surfaces between the carrier body and the glass container being carried, and thereby serve to isolate the glass container within the carrier body from one another. In situations in which the glass container would be subjected to crushing-type forces, these ribs, of generally U-shaped cross section, would act as stiffening agents around the peripllery of the carrier and tend to resist carrier body wall deformation. Under situations in which the glass container would be vulnerable to impact-type forces, includiny those generated by dropping, the ribs maintain a protective air space around most of the glass container and allow the local deformation of the carrier body to absorb energy from the impact with minim.-ll ~amage to the glass container within.
As can be seen from Figure 3, the shape of the side ribs 12 is somewhat different from the shape of the ribs 13 found on the bottom of the carrier body. This was _~;_ ll;~Z909 found advan-tageous in view of the probable weignt distribution withill the c~arrier. In an upright position, the entire weigllt of the glass container will rest on the bottom ribs. By sharpening the apex of the rib on the outside bottom of the carrier body, the corresponding inner rib surface, upon blow-molding, approaches a semicir~ular or V-shaped cross section, which would maximize rib strength with respect to forces directed to the bottom of the carrier body.
Again referring to Figure 3, the bottom of the container body 14 has been designed to maximize container stability when the container is in an upright position.
This has been accomplished in two ways. First, the bottom has been designed to present a relatively flat surface, substantially free of bumps or other surface projections such as rnold marks, identification numbers, etc. In addition, the bottom design calls for a ~elatively small radius of curvature where bottom and side wall meet, as at 15.
This will allow for more contact and support around the outer edges of the bottom, and will greatly increase the carrier's resistance to tipping.
Referring now to Figure 2, handle 20 is made of a single piece of heavy gage metal rod having opposite ends 23 and 24. The rod should be of sufficient strength to resist permanent deformation under maximum forseeable loads--a mild steel rod of approximately 3~16 inch has been found staisfactory. A plastic covering on the handle is suggested to reduce slippage and ofrer some cushioning for the hand.
1~L2Z909 The handle 20 i5 prebent and attached to the carrier body 10 through a pair of opposing holes 21 and 22 in the body 10. Each end of handle 20 is prebent in two places, with a small portion of the handle projecting approximately perpendicular through the carrier wall, and the end-most segment of each said projecting portion being bent so that each end segment of the handle ultimately lies along the inside surface of the carrier. It should be noted that the opposite ends of the handle 20, noted as 23 and 24 in Figure
2, are bent so that, with the handle in the lifting position, ends 23 and 24 will be roughly horizontal, and will face in opposite circumferential directions. This serves to lock the handle to the carrier body by resisting any tendency for the handle to deform and pull free under extreme loads. Lip 25 extends around the circumference of the rim of carrier body 10, and is designed to afford a seal in cooperation with a corresponding circumferential rib, depicted as feature 32 on lid 30 in Figure 4, and discussed in more detail below.
Lid 30 is depicted in Figures 1, 4 and 5. It is made of the same material, and in the same relative thick-ness, as carrier body 10. As can be seen in Figure 4, the lid comprises a flange or skirt 31 extending from a circumferential inwardly pro~ecting rib 32. Rib 32 is designed to be engaged underneath the circumferential lip 25 on carrier body 10 to removably hold the lid in place with the upper rim of the carrier body engaging the underside of the top of the lid. With the lid 30 placed on top of carrier bod~
10, downward pressure on the lid will cause rib 32 on lid 30 to "snap" over the protruding lip 25 of the carrier body, thus sealing the lid 30 to ~Z2909 the carrier body 10. Subsecluent release of this seal is ~acil -tated by sXirt 31, which increases available pur-chase and allows finger pressure to be more easily and directly applied to the seal to force rib 32 back over lip 25, permitting removal of the lid.
Lid 30 also comprises dome 33, which is of generally conical shape except for integral keyway area 34. The shape, position, and proportion of this dome are designed to protect the neck and carrying handle of standard glass laboratory solvent containers; when the lid is secured to the carrier body, this dome becomes part of a carrier system which can provide total protection ayainst mechanical shock or other handling ha~ards. Keyway area 34 can accommodate a jug-type carrying handle, thereby protecting the handle of the container and constraining rotational motion of the container. The central aperture 35 in the top of dome 33 p-ovides access to the container and its contents without having to compro.~ise this total protection. The container in -the carrier may either be opened conventiollally and the lid to the carrier replaced after tubiny or other delivery means has been ins-talled -throuc~h aperture 35, or a hole may be drilled or punched -through aperture 35 into the top of the container, and tubing or other means installed without haviny to unseal lid 30 at all.
r~ith respect to the method of manufacture, a blow-molding process has been used with considerable success, although it is not intended that fabrication of the subject carrier be limited to this process. In the blow-molding process, the selected material of composition, for exarlple a polyethylene plas-tic, is heated to a molten state and formed into a hollow tube or parison. This hollow parison is suspended above a relatively thin hollow rod called a blow pin, and the parison is allowed to flow down around the blow pin in a cylindrical sheet.
llZZ909 The molten plastic is not of uniform thickness to com-pensalie for differences in the desired thickness or~ the final container, e.g., a relatively thick, strong bottom, and to compensate for the forees of gravity. At a precisely eontrolled time, a relatively air-tight mold is elamped around this eylindrical sheet of molten plastic, and air at high pressure is introduced from an aperture in the end of the blow pin. The resulting pressure forces the molten plastic to conform to the inside surfaces of the ~old, thereby formincJ the plas-tic ir.to the desired shape. It has been found eonvenient to form the earrier body and the lid as one structure, with a eircumferential band of expendable rslaterial connecting the carrier body with the lid. The hole in the to2 of the lid is made as a convenient by-product of the overall blow-molding process. The blow pin, protrudinc3 into the eentral area of the mold from above, automatically forms a rouc~h hole in the top of the earrier. This rough hole may then be trimmed during subsequent operations.
Once the plastic in the mold has cooled, the carrier-~lus-lid structure is removed from the mold, and the lid is separated from the carrier body by cutting along a line parallel to the earrier body top and che lid bottom, direetly through the aps-~roximate midpoint of the circum-ferential band oE eY.pendable material. The expendable material may then be trimmed from both lid and carrier body so that lid and carrier body may then be snapped together and used as a unit.
Lid 30 is depicted in Figures 1, 4 and 5. It is made of the same material, and in the same relative thick-ness, as carrier body 10. As can be seen in Figure 4, the lid comprises a flange or skirt 31 extending from a circumferential inwardly pro~ecting rib 32. Rib 32 is designed to be engaged underneath the circumferential lip 25 on carrier body 10 to removably hold the lid in place with the upper rim of the carrier body engaging the underside of the top of the lid. With the lid 30 placed on top of carrier bod~
10, downward pressure on the lid will cause rib 32 on lid 30 to "snap" over the protruding lip 25 of the carrier body, thus sealing the lid 30 to ~Z2909 the carrier body 10. Subsecluent release of this seal is ~acil -tated by sXirt 31, which increases available pur-chase and allows finger pressure to be more easily and directly applied to the seal to force rib 32 back over lip 25, permitting removal of the lid.
