Defendant appeals his conviction for possession of methamphetamine, a controlled substance. ORS 475.992-(4)(b). He assigns error to the denial of his motion to suppress evidence of controlled substances seized from a coin purse in a briefcase. We affirm.
Police received a telephone call that a suspicious person was loitering around an inoperative phone booth for about 45 minutes. An officer was dispatched to the location. When he arrived, he saw defendant with a bicycle near the booth. The officer contacted defendant, who identified himself. Based on that identification, the officer learned that there was an outstanding warrant for defendant’s arrest. He arrested defendant and then searched defendant for weapons before placing him in his patrol car. In defendant’s pocket, he found a glass jar with green vegetable material in it. In the officer’s experience, the empty can with holes punched in it was consistent with a can that is used to smoke marijuana. The officer then turned his attention to the bicycle, on which there was a briefcase. At that point, police department policy required the officer to impound the bicycle together with any personal property in the possession of defendant. The officer asked defendant about the briefcase on the bicycle. The trial court found that, “[t]he defendant disclaimed any interest in a briefcase that was attached to the bicycle and said it did not belong to him.”
The officer removed the briefcase from the bicycle because it was to be stored at a different location from the bicycle. While handling the briefcase, the officer felt a heavy cylindrical object in it that was consistent with the size and shape of a beverage can. The officer thought that the object might be a can containing an alcoholic beverage, a beverage not permitted to be kept in the j ail facility to which defendant would be transported. On opening the briefcase, the officer discovered an unopened can of beer and another empty can with holes punched in it. The officer also found a coin purse located in a pocket of the briefcase. He opened the coin purse and discovered a powdery substance that he suspected to be methamphetamine. The officer put the coin purse back inside *538the briefcase and took defendant, the bicycle and the briefcase to the Marion County Correctional Facility.
At the correctional facility, defendant was booked by another officer. The booking officer was not informed about the contents of the coin purse. As part of the booking process, the officer inventoried the property that defendant had with him. He opened the briefcase, searched its contents, discovered the coin purse, opened it and found the powdery substance. Defendant told the officer conducting the inventory that the briefcase was his. The contents of the coin purse were subsequently seized and tested positive for methamphetamine, resulting in the indictment in this case.
Before trial, defendant moved for an order suppressing the evidence of the methamphetamine under Article I, section 9, of the Oregon Constitution, and the Fourth Amendment of the United States Constitution. He did not claim a personal possessory or ownership interest in the briefcase in support of his motion1 and did not testify in the hearing on the motion to suppress. The state offered the testimony of the officer who made the arrest and the testimony of the officer who conducted the inventory. On redirect examination of the officer conducting the inventory, the prosecutor elicited testimony that, during the inventory, defendant admitted that the briefcase was his. The trial court denied defendant’s *539motion, reasoning that defendant’s disclaimer of any interest in the briefcase at the scene of the arrest “might in and of itself be enough to deny the motion here. Assuming arguendo that I’m wrong * * * then I’m going onto the second bas[i]s of the inevitable discovery in the administrative search process.”
Defendant then waived a jury trial and entered into a stipulation of facts. The stipulation does not mention the officer’s observation of methamphetamine at the scene of the arrest. On appeal, defendant assigns error to the trial court’s rulings. He argues that the trial court erred in denying his motion as to the officer’s observation at the scene of the arrest and makes several arguments regarding the inventory at the correctional facility. Assuming without deciding that the trial court’s ruling about the officer’s observation at the scene of the arrest is error, it is harmless. That evidence was not part of the evidence that led to defendant’s conviction because it was not part of the stipulated facts at trial. Also, the arresting officer did not tell the inventory officer about his observation, and, therefore, the inventory is not derivative of the observation.
As to the inventory process, defendant told the trial court:
“This matter could have been inventoried as a closed container. In fact, should have been inventoried as a closed container. The jail people have access to the courts. They had these facts to constitute probable cause to get a search warrant to search that item.”
In his memorandum to the trial court, defendant relied in part on our holding in State v. Ridderbush, 71 Or App 418, 426, 692 P2d 667 (1984). In that case, we held that section 9 required that a small black box being inventoried by police, pursuant to an inventory policy, was to be listed by its outward appearance and that no closed, opaque container could be opened to determine what, if anything, was inside. Id. at 426.
We followed our holding in Ridderbush in State v. Maynard, 149 Or App 293, 942 P2d 851 (1997), in which we *540held that it was unlawful to open a match box during an inventory. We said:
“In this context, opening a container to determine its contents is not part of an inventory but is a search: it is an attempt to learn whether the container holds contraband or a threat to the officer’s security. As Ridderbush holds, the Oregon Constitution does not permit a search unless the officer has a warrant or there is an exception to the warrant requirement.” 149 Or App at 297.
The state argues that our holding in Ridderbush is not dispositive, relying on State v. Mundt/Fincher, 98 Or App 407, 780 P2d 234, rev den 308 Or 660 (1989). In that case, we held:
“Ridderbush does not control the inventory of a wallet or a purse. Neither a wallet nor a purse is a ‘closed, opaque container.’ * * * [A] wallet typically has openings for inserting money, credit cards and other valuables; even when folded shut, it is not ‘closed’ in the way that the box in Ridderbush was. A purse usually has compartments for storing money and other valuables and frequently holds a wallet. Because wallets or purses are primarily intended to be used to store valuables, it may be important to discover what is in them, both to protect the owner’s property and to prevent the assertion of false claims against the police. See ORS 133.455. Both are legitimate purposes for inventories of impounded property.” Id. at 412 (emphasis supplied).
Similarly, the briefcase and the coin purse in this case are not “closed, opaque containers” because they are typically used to store valuables in the same way as a purse or a wallet. In that way, they are unlike the match box in Maynard or the small black box in Ridderbush. There, the opening of those containers constituted an “unreasonable” search under section 9 because, in an objective sense, those containers are generally not receptacles for valuables. On the other hand, a briefcase and a coin purse, when viewed objectively, are containers in which a reasonable person could expect to find valuables and to which an administrative policy designed to account for valuables would apply.2
*541The difference between the majority and the dissenting opinion in this case is in the characterization given to defendant’s briefcase. The dissent would hold that the officer conducting the inventory was required to inventory the briefcase as “one briefcase” without opening it to examine its contents. It reasons that “[u]nlike a wallet, a purse and even a fanny pack, a briefcase is not ‘uniquely designed’ to hold valuables. It is uniquely designed to carry papers or books.” 153 Or App at 549.
In State v. Bean, 150 Or App 223, 225, 946 P2d 292 (1997), the defendant was walking down the street wearing a fanny pack when he was taken into custody on a civil detoxification hold. At the police station, the police conducted an inventory of his wallet and the fanny pack. As a result of the inventory process, the defendant was charged with possession of a controlled substance. Id. at 227. On appeal, he challenged the validity of the inventory on the same grounds that defendant asserts in this case. We held that the Mundt/ Fincher rule was applicable and rejected the argument that the inventory of the fanny pack was unconstitutional in light of the holding in State v. Perry, 298 Or 21, 688 P2d 827 (1984).3 We held, “Like a wallet or a purse, a fanny pack is intended primarily to store valuables. Discovery and inventory of the items contained within those containers is important to protect the owner’s property and to prevent the assertion of false claims.” Bean, 150 Or App at 229.
Unlike the dissent, we discern no difference in function between the fanny pack in Bean and the briefcase in this case. Under the circumstances that existed in each case, each is a closed container that appears objectively to be intended primarily to store valuables in the same manner as a wallet or purse contains valuables. Those circumstances did not exist in State v. Keller, 265 Or 622, 625-26, 510 P2d 568 (1973), where a fishing tackle box in the defendant’s vehicle, typically used to store fishing tackle and not valuables, was required to be inventoried as “one fishing box.” Similarly, Perry was standing in front of a bus station with his suitcases *542or “steamer trunk” in his possession. Perry, 298 Or at 24. Under those circumstances, those containers would typically not be considered as receptacles for valuables in lieu of a wallet or purse.
In contrast, Bean was walking down the street wearing a fanny pack and defendant was next to a public phone booth in possession of a bicycle with a briefcase on it, when the officers observed them. Bean’s fanny pack was being worn in circumstances in which it could function like a wallet or purse. Similarly, defendant’s briefcase typically could have performed the same function and contained articles like money, credit cards, valuable papers, a lap top computer or a calculator. That is why the briefcase falls into a category of containers that are subject to an inventory to protect the owner’s property and to prevent the assertion of false claims and why a briefcase is distinguishable from articles like a matchbox, a steamer trunk and a fishing tackle box. The trial court did not err in denying defendant’s motion to suppress on the ground that the briefcase should have been inventoried without opening it.
Also on appeal, defendant argues for the first time that “the record does not establish a valid inventory policy” on which the inventory was based because “it does not demonstrate what politically accountable authority promulgated the inventory policy” and that the policy “was not ‘noninvestigative.’ ” A valid inventory policy consists of a properly authorized administrative program, designed and systematically administered so that it involves no exercise of discretion by the officer taking the inventory. State v. Atkinson, 298 Or 1, 11, 688 P2d 832 (1984).
As part of his motion to suppress, defendant’s counsel initially offered an affidavit in which he averred, “[t]hat any inventory associated with the Defendant which is a closed container should not have been searched and must be inventoried as a closed cor twiner when the Defendant is lodged at the jail.” In its resj. se in the trial court to defendant’s motion and the affida’ the state supplied the court with excerpts of the Marion nnty Department of Correction Policy which provides, in ¡art, for the inventory of personal property of an inmate f r valuables including jewelry *543and money. Thereafter, defendant filed a further memorandum in support of his motion in which he did not contest the lawfulness of the inventory policy, its scope or whether it was promulgated by politically accountable officials. At the hearing on the motion, defendant argued only that “this matter should have been inventoried as a ‘closed container.’ ” The trial court concluded that a “valid inventory search was conducted.”
The trial court has never had an opportunity to decide the issues presented by defendant’s new argument on appeal. Moreover, in the absence of such a challenge below, the state has had no opportunity to meet those issues other than through its proffer in its initial memorandum, a proffer that was uncontested in the trial court. In State v. Custer, 126 Or App 431, 435, 868 P2d 1363 (1994), we said that, “even when the issue is not raised by the parties, a reviewing court must make a determination as to the authority under which the police impounded and inventoried the vehicle, as a prerequisite to declaring the inventory valid.” See also State v. Cook, 136 Or App 525, 529 n 4, 901 P2d 911, rev allowed 322 Or 420 (1995). We relied on the following language in Atkinson for that proposition: “Apparently the parties and the court assumed that the vehicle was lawfully impounded. However, as a prerequisite to a lawful inventory, a determination as to the authority under which the police impounded the vehicle is necessary.” 298 Or at 11. In Atkinson, the court remanded so that the trial court could make such a determination. Here, the trial court in its oral ruling said: “[The arresting officer] then took the defendant to * * * jail where a valid inventory search was conducted of all the defendant’s property including this briefcase.”
The rule of preservation of issues below for purposes of appeal is a judicially created rule of utility. It should only be applied where its purpose is fulfilled, and it should be applied across the board to all issues. Moreover, there is no discussion in Atkinson that suggests that the court contemplated creating an exception to ORAP 5.45(2) for inventory issues. Those concerns lead us to conclude that our application of the Atkinson language to the circumstances in Custer and the cases that follow it was error. If we were to adopt the rule of Custer under the circumstances of this case, it would *544permit defendant to challenge on appeal for the first time what had not been contested below, the court’s implicit ruling on the sufficiency of the state’s evidence about its inventory policy. Such a result would effectively eviscerate ORAP 5.45(2). Under the circumstances, we hold that defendant did not preserve the issue that he now raises on appeal about the validity of the inventory policy. ORAP 5.45(2). In sum, the trial court did not err in denying defendant’s motion to suppress.
Affirmed.
